Ich bin eher so ein wandelndes Bachelor-Studium.The resulting instruments will be valuable to researchers and practitioners investigating the relationship between opportunity recognition and opportunity exploitation and, in turn, their relationships with other variables.
As such, they could advance research examining the antecedents and consequences of both concepts. This study therefore contributes to the literature on opportunity research in three important ways.
First, researchers clearly define both constructs in a rigorous way, thus informing the theoretical discussion around opportunity recognition and opportunity exploitation.
Second, rigorously developed measurement scales for both constructs will allow future research to investigate these constructs in a plethora of different research settings.
Finally, the analysis contributes to the research stream of entrepreneurial opportunities by painting an elaborate nomological net around these constructs illustrating important relationships with other key constructs in opportunity research.
Such situations may appear as unmet customer and market needs, or under-employed resources and are likely to emerge when change occurs, new information becomes available, or the marketplace is subject to incongruence.
Following this logic, the current research treats opportunity recognition and opportunity exploitation as distinct Jarvis, , but often consecutive, steps in the entrepreneurial process.
Nevertheless, a closer look at the burgeoning number of studies on opportunity recognition and opportunity exploitation reveals serious issues impeding improved understanding.
Many studies do not, for example, specify the content domain of the concepts, and make implicit assumptions on what constitutes opportunity recognition or opportunity exploitation Kuratko et al.
Sambasivan et al. Many studies use single-item measures that are often purely numerical e. Singh et al. Tumasjan and Braun, Some studies develop ad hoc scales without reporting rigorous reliability and validity testing e.
Nicolaou et al. Many studies that use opportunity recognition or opportunity exploitation as the independent or dependent variable refer to existing measures to justify their measures, but are not clear on how the measures employed were altered or extended e.
Ozgen and Baron, ; Sambasivan et al. Marked differences exist among the measures between the content domains of the constructs. For example, some studies indicate opportunity recognition is about innovative opportunities e.
Tumasjan and Braun, , while others exclude that dimension e. Another example is that some studies differentiate between opportunity-recognition perceptions and opportunity-recognition behaviors e.
Gibbs, , whereas others see both aspects as part of the same construct e. The vast majority of studies exclusively examine either opportunity recognition or opportunity exploitation, but do not address how the two concepts are interrelated, which may be related to the observation that literature has not provided a universally applicable distinct pair of measures for opportunity recognition and opportunity exploitation.
Shane and Nicolaou provide an initial step by capturing a tendency to recognize entrepreneurial opportunities and a tendency to start businesses in the same study.
However, they link both concepts to creativity as an anteceding factor and abstain from discussing their direct relationship. Overall, the lack of distinct measures for opportunity recognition and opportunity exploitation hinders obtaining an understanding of the similarities and differences concerning their antecedents and consequences.
There is a lack of consensus over: the definition and understanding of the content domains of opportunity recognition and opportunity exploitation, and the measurement of the two constructs.
Both issues hinder efforts to build a solid knowledge base on opportunity recognition and opportunity exploitation, one that would include aspects such as identifying the distinct antecedents of both constructs.
The current study addresses both issues. In order to clarify the assumptions relating to the meanings of the constructs, this study uses as its starting point the initial theoretical considerations and then surveys researchers familiar with the domain of entrepreneurship on which activities involve opportunity recognition and which involve opportunity exploitation.
This approach is in line with suggestions in the literature calling for topic experts to be involved in the process of scale development DeVellis, ; Slavec and Drnovsek, Accordingly, the research team developed an online survey and sampled academics with a professional interest in entrepreneurship research who subscribed to the Entrepreneurship-PhD mailing list [1].
Opportunity recognition and opportunity exploitation were considered to be behavioral, activity-based concepts that take place on the individual level.
Thus, apart from some descriptive elements, the survey predominantly comprised two open questions: Please share your ideas about opportunity recognition.
Assuming somebody perceives an entrepreneurial opportunity, be it a potential entrepreneur or corporate entrepreneur, what kind of activities would be involved?
If somebody has perceived an entrepreneurial opportunity and decided to act upon it, this step is usually called opportunity exploitation.
Assuming somebody acts upon a perceived entrepreneurial opportunity, be it a potential entrepreneur or corporate entrepreneur, what kind of activities would be involved?
Overall, usable responses had been received, commensurate with a response rate of Viewed alongside the high response rate, the non-significant results of a wave analysis comparing early respondents to late respondents on the demographic variables Armstrong and Overton, indicate non-response bias should not be an issue.
Academics from 37 countries provided responses, with researchers from Germany, the UK, and the USA dominating the first 40 percent of the sample.
With an average professional interest in entrepreneurship of 7. The respondents ranged from doctoral students As more than 84 percent of the respondents had at least 2.
Specific activities related to opportunity recognition and opportunity exploitation were compiled by two researchers in the author team from the qualitative data.
MAXQDA 10, a comprehensive software program for qualitative data analysis, was utilized to analyze the responses to the two open questions in an open-coding process based on the initial theoretical considerations.
Content analysis assisted the identification of 12 key activities: six activities reflecting opportunity recognition and six reflecting opportunity exploitation.
This result supports the assumption that the categories developed were appropriate. The six activities defining opportunity recognition in general were: being alert, searching, gathering information, communicating, problem solving, and evaluating.
These activities included but were not limited to cognitive processes involved in the entrepreneurial process Gregoire et al. First, being alert refers to creative and strategic thinking, which allows opportunity recognition Shane and Nicolaou, or having an open mind in terms of business opportunities Tang et al.
Second, searching is defined through the regular scanning of the environment and a systematic search for business opportunities, or by doing market research to identify business opportunities Fiet, Third, gathering information activities for instance relate to acquiring knowledge and information on business opportunities or to looking for new ideas on products or services Ozgen and Baron, Fourth, communicating refers to talking to friends, colleagues, potential customers, mentors, entrepreneurs, or experts about business opportunities Dimov, a.
Fifth, addressing customer needs refers to the generation of a business opportunity based on a perceived customer problem Ardichvili et al.
Sixth, evaluating involves assessing the feasibility of business ideas or whether proposed opportunities fit individual experience, skills, capabilities, and knowledge McMullen and Shepherd, As a consequence, a preliminary definition of the construct can be proposed; however, this definition might be modified in the scale-development process Slavec and Drnovsek, : Preliminary Definition 1.
Opportunity recognition is characterized by being alert to potential business opportunities, actively searching for and gathering information about them, communicating on them, addressing customer needs, and evaluating the viability of such potential entrepreneurial activities.
The six activities recorded as defining opportunity exploitation in general were: developing a product or service, acquiring human resources, planning the business, understanding customers and the market, gathering resources, and setting up the organization.
Just as with opportunity recognition, the activities identified perfectly aligned with but were not limited to existing concepts of nascent entrepreneurial activities and engaging in the startup and new venture development process.
First, developing a product or service involves, for instance, the innovative destruction of current products or services, prototyping and testing, and reacting to feedback Gartner et al.
Second, acquiring human resources is related to searching for or hiring employees, and assembling an entrepreneurial team to pursue business opportunities McGee et al.
Third, planning the business is based on the business model and the written business plan Shane and Delmar, Fourth, understanding customers and the market is defined through discussing and identifying customer needs, the evaluation of the acceptance of products or services by customers, and the comparison between the business opportunity and existing solutions Foss et al.
Fifth, gathering resources refers to building up a network, approaching investors or the government, and raising money from family and friends Haynie et al.
Sixth, setting up the organization is defined through the setting up of formal structures Gartner et al. The identified activities led to the following preliminary definition: Preliminary Definition 2.
Opportunity exploitation is characterized by developing a product or service based on a perceived entrepreneurial opportunity, acquiring appropriate human resources, planning the organization, understanding customers and the market, gathering financial resources, and setting up the organization.
Based on Preliminary Definitions 1 and 2, and the twelve activities they encapsulate, researchers developed a large initial item pool of candidates for inclusion in the scales DeVellis, Following suggestions in the literature, items were generated by conducting a literature review and examining existing scales related to the constructs Churchill, , as well as by obtaining expert input DeVellis, ; Slavec and Drnovsek, This resulted in 81 item candidates.
To evaluate content validity, the research team conducted another online survey and sampled additional active subscribers of the Entrepreneurship-phd mailing list who had not participated in the first stage of the scale development.
This step was intended to establish the content validity of each proposed item DeVellis, , that is, to clarify the extent to which experts on entrepreneurship would relate each single item to the two constructs under investigation.
Participants were asked to evaluate each of the 81 items with respect to the question of whether a specific item would reflect opportunity recognition or opportunity exploitation.
To help them do so they were presented with a five-point scale anchored with clearly describes opportunity recognition 1 and clearly describes opportunity exploitation 5.
The research team received 95 usable responses with similar demographics and quality criteria as in the first sample.
Participants placed each of the initial 81 items somewhere on the continuum between opportunity recognition and opportunity exploitation.
Inter-rater reliability was excellent: the average intra-class correlation of the ratings is 0. Figure 1 shows the aggregated results for the 12 key activities by visualizing the mean value of the activity captured by the average of the items belonging to that particular activity and its respective standard deviation.
Clearly, the activities can be ordered into a sequence from searching for an entrepreneurial opportunity at one end of the continuum toward gathering resources as the most unambiguous activity related to opportunity exploitation at the other.
This sequence is in line with other conceptualizations of entrepreneurial activities e. McGee et al. In summary, the expert evaluation found that 11 items described opportunity recognition and 13 items described opportunity exploitation.
These items are analyzed in greater detail in the next step. In this section, the 24 items retained are examined for construct validity in order to develop the final scales.
For this, researchers chose to collect data first in a corporate entrepreneurship setting before retesting the scales in an entrepreneurship setting.
This was done for several reasons. First, and in line with recent scale-development practice Tang et al. Second, literature suggests that not only researchers, but also practitioners should participate in the scale-development process Slavec and Drnovsek, Third, the rationale behind preferring a corporate entrepreneurship sample to a more entrepreneurial sample in the item-refinement step of the scale-development process relates to the generalizability requirement Tang et al.
From one perspective, in order to create sufficient variance, the goal was to select a population of which a substantial part could be expected to be recognizers of entrepreneurial opportunities and another substantial part could be expected to be non-recognizers of the same Kuratko et al.
By contrast, researchers were aware the final scales should be applicable in both the pure entrepreneurship and the corporate entrepreneurship context, for instance to assess the relationship between organizational design and opportunity recognition and opportunity exploitation in established firms.
An online questionnaire including the 24 items was administered in English to executive managers working in firms included on the Dow Jones Global Titans 50 Index.
Executive managers are known to play an important role in the success of corporate entrepreneurship initiatives Hornsby et al.
Recruitment was conducted through an international professional online network boasting more than 11 million members at the time of data collection. Its comprehensive nature allowed the identification of network members employed in Global Titans 50 firms proportionate to the coverage of the firm in the index.
We received usable responses from executive managers, commensurate with a satisfying response rate of In a wave analysis Armstrong and Overton, comparing all 24 items in addition to the key descriptive variables in the data did not return a single significant difference.
Again, non-response bias should therefore not be considered an issue. Respondents were on average The number of male respondents substantially exceeded that of female respondents The sample consists of well-educated people, with only The reliability and validity of the measurement were established by examining the psychometric properties of the constructs, in particular, by employing exploratory and confirmatory factor analyses alongside other correlational analyses.
The final scales were identified following several iterations refining the model. First, all items loaded on their respective factor, and no item had to be eliminated because of substantial cross-loadings.
Moreover, 13 items were eliminated as either their measurement errors were substantially correlated or their wording seemed theoretically redundant.
The final scales consisted of five items on the opportunity recognition scale and four items on the opportunity exploitation scale.
Corrected item-total correlations ranged from 0. In this sample, the minimum value of opportunity recognition was 1 and the maximum value 7 measured on a seven-point Likert scale , with a mean value of 4.
Corrected item-total correlations range from 0. In this sample, the minimum value of opportunity exploitation is 1, the maximum is 6.
The mean values suggest that the scales adequately reflect the corporate setting. In the CFA, as suggested in the literature, multiple indices were used to assess fit Beauducel and Wittmann, Given established standards Hair et al.
The square roots of the variance extracted for each measure are greater than the correlation, suggesting that opportunity recognition and opportunity exploitation are distinct.
Furthermore, to statistically assess the mode reflective vs formative of the relevant scales, the research team ran a confirmatory tetrad analysis CTA Gudergan et al.
The CTA returned insignificant results for every single tetrad, which suggests that both measurement models are reflective. Table I presents the final scales.
Next, researchers conducted a retest of the validity of the newly developed scales, using a different sample with an entrepreneurial background to enhance the credibility of the measures and to support generalizability across samples Tang et al.
The process continued with an evaluation of the convergent, discriminant, and nomological validity of the newly developed scales.
The scales for opportunity recognition and opportunity exploitation were included in a survey targeting UK entrepreneurs.
To identify those entrepreneurs, the research team chose an internet panel provider, which selected survey participants based on its master data.
On average, the respondents had been entrepreneurs for Hence, the team concluded the sample had sufficient experience to report on entrepreneurial phenomena.
This section demonstrates that the scales for opportunity recognition and opportunity exploitation relate to other measures they would theoretically be expected to relate to.
However, this relatedness should not be of a magnitude that would signal construct redundancy. Kirzner established that alertness is an ability central to the entrepreneurial process because it makes individuals aware of changes, shifts, and opportunities overlooked by others Tang et al.
Entrepreneurial alertness involves not only gathering, associating, and evaluating information on business opportunities, but is also linked to action and as such with the willingness to act on the business opportunity Tang et al.
Hence, it can be assumed that entrepreneurial alertness is strongly related to both opportunity recognition and opportunity exploitation. However, the relationship of entrepreneurial alertness with opportunity recognition will be stronger than with opportunity exploitation, as the activities of gathering, associating, and evaluating information are more proximate to recognizing an opportunity than to exploiting it: H1.
Opportunity recognition will demonstrate a stronger positive correlation with the entrepreneurial alertness dimensions than opportunity exploitation.
Following Aldrich and Martinez , nascent entrepreneurial behaviors are meant to result in a feasible business startup.
Such behaviors encompass growing and assembling various resources, including knowledge, which can be combined into an organization Gartner et al.
Nascent entrepreneurial behaviors thus involve both acquiring knowledge about the opportunities available to start a business and combining resources to pursue an opportunity once identified McGee et al.
Opportunity exploitation will demonstrate a stronger positive correlation with nascent entrepreneurial behaviors than opportunity recognition.
Testing H1 and H2 was conducted using the sample detailed in the section on retesting. Entrepreneurial alertness dimensions were captured with the scales developed by Tang et al.
With respect to nascent entrepreneurial activities, a variety of lists of behaviors have been developed in the extant literature see Gartner et al.
Researchers decided to apply the six behaviors depicted by McGee et al. This study applies a structural equation modeling approach using AMOS to test its hypotheses.
With respect to H1 , researchers ran a series of confirmatory factor analyses and a correlation analysis. Researchers began with a one-factor model in which all the items of opportunity recognition, opportunity exploitation, and the three alertness dimensions loaded on the same factor.
Next, a five-factor model with one factor representing each of the variables was estimated. For computing correlations, AMOS was employed to benefit from incorporating the different weights of the items of a given construct.
Opportunity recognition correlated with alert scanning and search at 0. Opportunity exploitation correlated with alert scanning and search at 0.
As expected, opportunity recognition correlated more strongly with all entrepreneurial alertness dimensions than did opportunity exploitation.
Given the stronger relationship between entrepreneurial alertness and opportunity recognition than with opportunity exploitation, researchers excluded the opportunity exploitation factor from additional testing.
Again, the multi-factor model outperformed the model in which the entrepreneurial alertness dimensions and opportunity recognition were collapsed into one factor.
This also holds true for any pairwise combination of a single alertness dimension and opportunity recognition. Viewed as a whole, the results reveal that opportunity recognition, opportunity exploitation, and entrepreneurial alertness are strongly related but distinct concepts.
With respect to H2 , researchers ran a series of confirmatory factor analyses, and a correlation analysis.
Researchers began with a one-factor model in which all the items of the three scales opportunity recognition, opportunity exploitation, and nascent entrepreneurial activities loaded on the same factor.
Next, a three-factor model with one factor representing each of the variables was estimated. Supporting H2 , opportunity exploitation 0.
Given the stronger relationship between nascent entrepreneurial activities and opportunity exploitation than between nascent entrepreneurial activities and opportunity recognition, the opportunity recognition factor was excluded from additional testing.
Again, the multi-factor model outperformed the model in which nascent entrepreneurial activities and opportunity exploitation were collapsed into one factor.
Taken together, convergent validity of the scales was established, as the results show that opportunity recognition, opportunity exploitation, and nascent entrepreneurial activities were closely related but distinct concepts.
Any construct validation process involves demonstrating nomological validity. To do so, researchers assessed how opportunity recognition and opportunity exploitation behave within systems of related constructs i.
Specifically, researchers established nomological validity by applying two samples and multiple models. The chosen antecedent and consequent variables are grounded in extant theories of human capital, innovation, and organizational emergence and revealed the similarity and differences in the links between opportunity recognition and opportunity exploitation with other variables.
Following the prospect theory logic presented by Baron , corporate entrepreneurs can be risk takers who aim not to overlook an opportunity; that is, they tend to recognize opportunities.
Furthermore, they act upon opportunities to avoid losses they would incur if they were not to act; that is, they tend to exploit opportunities.
This theory is also about a tendency to overemphasize small probabilities. Indirect support is provided by the work of Sambasivan et al.
Risk taking is positively associated with opportunity recognition and directly and indirectly associated with opportunity exploitation. The concept of originality is strongly associated with the concepts of innovativeness and creativity Miron-Spektor et al.
In order to identify business opportunities corporate entrepreneurs have to be able to find innovative solutions to customer problems Baron, ; Hansen et al.
The literature includes many theoretical assertions linking creativity and opportunity recognition Dimov, b. In line with these theoretical assertions, Gielnik et al.
Dess and Lumpkin theoretically link innovativeness to the exploration of business opportunities, but not to their exploitation.
Only recently, Shane and Nicolaou have found that creative personalities exhibit a greater tendency to recognize business opportunities.
They also found that creative personalities are more likely to start a new business. However, given these contradictory assertions, and because these studies do not directly address originality and opportunity exploitation, they cannot be interpreted as clear indications of a relationship between these variables.
As there are neither theoretical assertions nor empirical findings directly and indisputably linking originality and opportunity exploitation, researchers do not hypothesize this direct relationship: H4.
Originality is positively associated with opportunity recognition and indirectly positively associated with opportunity exploitation.
Prior knowledge refers to the information individuals hold on a subject matter and it increases the likelihood of a person successfully recognizing and exploiting a business opportunity Shepherd and DeTienne, Prior knowledge is positively associated with opportunity recognition and opportunity exploitation.
Positive affect refers to feelings or emotions reflecting a pleasurable engagement with the environment, such as enthusiasm, excitement, or joy Watson et al.
Positive affect influences how information is retained and processed and has been found to play a role in alertness and opportunity recognition, and its consequences, such as the acquisition of essential financial and human resources, or innovation Baron, : H6.
Positive affect is positively associated with opportunity recognition and opportunity exploitation. From a process perspective, innovation usually refers to the identification and utilization of business opportunities to create new products, services, or markets.
Innovation begins with the selection of an idea identified as a business opportunity and ends with the commercialization of the invention Amabile et al.
The act of exploiting an opportunity should lead to an innovation, whether truly radical or less so. Tang et al. Was hast du bei den bisherigen Dreharbeiten alles erlebt?

In order to identify business opportunities corporate entrepreneurs have to be able to find innovative solutions to customer problems Baron, ; Hansen et al.
The literature includes many theoretical assertions linking creativity and opportunity recognition Dimov, b. In line with these theoretical assertions, Gielnik et al.
Dess and Lumpkin theoretically link innovativeness to the exploration of business opportunities, but not to their exploitation. Only recently, Shane and Nicolaou have found that creative personalities exhibit a greater tendency to recognize business opportunities.
They also found that creative personalities are more likely to start a new business. However, given these contradictory assertions, and because these studies do not directly address originality and opportunity exploitation, they cannot be interpreted as clear indications of a relationship between these variables.
As there are neither theoretical assertions nor empirical findings directly and indisputably linking originality and opportunity exploitation, researchers do not hypothesize this direct relationship: H4.
Originality is positively associated with opportunity recognition and indirectly positively associated with opportunity exploitation. Prior knowledge refers to the information individuals hold on a subject matter and it increases the likelihood of a person successfully recognizing and exploiting a business opportunity Shepherd and DeTienne, Prior knowledge is positively associated with opportunity recognition and opportunity exploitation.
Positive affect refers to feelings or emotions reflecting a pleasurable engagement with the environment, such as enthusiasm, excitement, or joy Watson et al.
Positive affect influences how information is retained and processed and has been found to play a role in alertness and opportunity recognition, and its consequences, such as the acquisition of essential financial and human resources, or innovation Baron, : H6.
Positive affect is positively associated with opportunity recognition and opportunity exploitation. From a process perspective, innovation usually refers to the identification and utilization of business opportunities to create new products, services, or markets.
Innovation begins with the selection of an idea identified as a business opportunity and ends with the commercialization of the invention Amabile et al.
The act of exploiting an opportunity should lead to an innovation, whether truly radical or less so. Tang et al. Both opportunity recognition and opportunity exploitation are positively associated with innovations.
Starting a new business can be considered a central objective of entrepreneurship Gartner, Consequently, engaging in the entrepreneurial process and succeeding in the recognition and exploitation of a business opportunity should ultimately lead to starting a new business in the end.
We assume that people with the capability to recognize and exploit opportunities matched with a willingness to do so, will found more new businesses than people lacking such capability and willingness: H8.
Both opportunity recognition and opportunity exploitation are positively associated with the number of businesses started. The testing of H3 and H4 relied on the sample detailed in the section on item refinement, while testing H5 - H8 relied on the sample detailed in the section on retesting.
In both samples, opportunity recognition and opportunity exploitation were captured using the items developed in this study. To measure originality, corresponding items of the Kirton-Adoption-Innovation inventory were included in the analysis Kirton, ; Kuckertz and Wagner, Items taken from the instrumental risk-taking scale of Zaleskiewicz were adopted to provide an entrepreneurship-relevant measure of attitude to risk.
Prior knowledge was measured in the same way as described by Tang et al. The number of businesses started is a single item taken from Nicolaou et al.
This study applied a structural equation modeling approach using AMOS to test its hypotheses. With respect to H3 , researchers conducted a mediation analysis.
As had been anticipated, risk-taking propensity associated with opportunity recognition 0. Equally, as hypothesized, risk-taking propensity 0.
The indirect effect of risk taking on opportunity exploitation via opportunity recognition was also significant 0. A further mediation analysis was conducted to test H4.
Again as assumed, originality did not affect opportunity exploitation 0. The indirect effect of originality on opportunity exploitation via opportunity recognition was significant 0.
With respect to H5 - H8 , researchers created a more complex model that included multiple antecedents positive affect, prior knowledge and consequences innovation, number of businesses started of opportunity recognition and opportunity exploitation.
The results obtained from evaluating the hypotheses indicate that prior knowledge is positively linked to both opportunity recognition 0.
H6 was also supported, because positive affect was positively associated with both opportunity recognition 0. Notably, prior knowledge and positive affect are significantly correlated 0.
As expected, opportunity recognition was associated with opportunity exploitation 0. Prior knowledge, positive affect, and opportunity recognition explained 55 percent of the variance in opportunity exploitation.
Moving to the consequences of opportunity recognition and exploitation, H7 was supported in that both opportunity recognition 0.
Both variables explained 55 percent of the variance in innovation. H8 was partially supported as 10 percent of the variance in numbers of businesses started can be explained by opportunity recognition and opportunity exploitation.
As expected, opportunity exploitation was linked to the number of business started 0. Contrary to the proposed hypothesis, however, no direct link was found between opportunity recognition and the number of businesses started —0.
An analysis of the indirect association between opportunity recognition and number of businesses started via opportunity exploitation did however reveal a significant indirect effect 0.
Consequently, not finding a direct effect should not be taken as an indication that opportunity recognition is irrelevant in explaining the number of businesses started.
Rather, it indicates that recognized opportunities have to be exploited to culminate in new businesses.
Taking the results of the examination of H3 - H8 together, one can conclude that how opportunity recognition and opportunity exploitation behave in a nomological net is in line with extant theory, indicating nomological validity.
The preceding sections already provided an initial indication of discriminant validity, because both opportunity recognition and opportunity exploitation had insignificant relationships with other variables and because those non-significant relationships are in line with theoretical considerations.
The following section offers additional evidence of discriminant validity by reporting the results of testing the relationships to variables, which theoretically should not be present for either opportunity recognition or opportunity exploitation.
Contrary to positive affect, which has been found to relate both to opportunity recognition and to opportunity exploitation, negative affect should relate to neither.
Negative affect refers to feelings or emotions that reflect an unpleasant engagement with the environment, such as one resulting in distress, upset, or fear Watson et al.
It has also been linked to behaviors aiming to reduce risks Iyengar et al. In line with recent research Tang et al. Both opportunity recognition and opportunity exploitation will demonstrate discriminant validity with negative affect.
Contrary to the number of businesses started, this study argues that the time an individual has spent being self-employed will not relate to either opportunity recognition or opportunity exploitation.
An individual with the ability and willingness to recognize or exploit opportunities, or to combine both is more likely to become self-employed.
It follows that after a period of time such an individual is likely to identify a new opportunity and may decide to pursue it. An individual with a weak or moderate tendency to recognize and exploit opportunities may stay in their current employment area.
In both cases, the time in self-employment would be same, precluding a clear correlation: H Both opportunity recognition and opportunity exploitation will demonstrate discriminant validity with the length of time an individual has been self-employed.
H9 and H10 were tested using the sample detailed in the section on retesting. Opportunity recognition and opportunity exploitation were captured using the items developed in this study.
Time spent self-employed is a single item taken from Nicolaou et al. A structural equation modeling approach using AMOS was adopted to test the hypotheses.
With respect to H9 , negative affect correlated significantly with neither opportunity recognition 0. Taken together, the results help to establish discriminant validity.
Figure 2 summarizes all relationships discussed and illustrates the elaborate nomological net of opportunity recognition and opportunity exploitation.
The current research underlines the importance of differentiating between opportunity recognition and opportunity exploitation. Its aims were to develop definitions for both constructs and also to generate distinct measures to capture them.
The findings reveal that opportunity recognition and opportunity exploitation are in fact multifaceted activities.
Initially, research identified six activities defining opportunity recognition and six defining opportunity exploitation, and accordingly initial definitions of both constructs were adopted.
Given the results obtained in the item-positioning task, the need for distinct definitions and measures, and the validity testing of the proposed scales, it seemed wise to refine those preliminary definitions.
Those refinements are presented below: Final Definition 1. Opportunity recognition is characterized by being alert to potential business opportunities, actively searching for them, and gathering information about new ideas on products or services.
Opportunity exploitation is characterized by developing a product or service based on a perceived entrepreneurial opportunity, acquiring appropriate human resources, gathering financial resources, and setting up the organization.
Redefining constructs after further process steps is commonplace in understanding constructs and developing appropriate measures Slavec and Drnovsek, It is important that any new definitions are in line with the basic idea of what the construct should represent and are also reconcilable with theory; and the new definitions above meet both criteria.
As can be seen in Figure 1 , the evaluation activity was not positioned as describing opportunity recognition, but rather somewhere in the indeterminate zone between opportunity recognition and opportunity exploitation.
This insight is in line with basic assumptions on the entrepreneurial process. As a distinct process, it should be separated both theoretically and empirically from opportunity recognition and opportunity exploitation.
Recent experimental research by Welpe et al. In addition, the communication and customer-understanding activities that were part of the initial definitions have been removed.
In Figure 1 , both activities were placed close together and around the indeterminate area. In addition, the communicating and customer-understanding activities that were part of the initial definitions were subsequently removed because they proved vague.
From a conceptual point of view, it is hard to see relevance of opportunity recognition in communicating with other people when it is not aimed at gathering information on the opportunity which is a different activity.
Communicating may help corporate entrepreneurs to evaluate the viability of an idea, but that would be a different construct. Additionally, some people tend not to talk about their ideas for fear of others stealing them.
In the same manner, understanding customers is, at least to some extent, included in the activities of gathering information and developing a product or service.
Was hast du bei den bisherigen Dreharbeiten alles erlebt? Ich bin in einer vierzig Kilo schweren Ritterrüstung auf ein Riesenpferd gestiegen und habe alleine eine Ritterburg gestürmt, hab mich auf einen knapp 50 Meter hohen Baukran getraut und musste für die Sendung über unsere Sinne Eis aus Senf und Bratensauce erschmecken — das war ganz schön eklig.
Wie viel "Checker" steckt in dir? Darum: Prozent! Versuchst du, dich an Can zu orientieren — oder bist du ganz anders?
Can und ich sind auf jeden Fall sehr unterschiedlich, was auch gut ist: er hat seinen Stil, ich meinen, und das macht das Format noch bunter und unterhaltsamer.
Can und ich haben aber auch was gemeinsam: Wir haben beide tierisch Höhenangst. Du hast ja vorher schon als Moderator gearbeitet — was ist bei "Checker Tobi" neu für dich?
Mit einem Regisseur beim Dreh ist es für mich leichter, mich auf meine Fragen und meine Gesprächspartner zu konzentrieren. Ich kann mich komplett darauf einlassen, Sachen rauszufinden und muss mich nicht ständig fragen, ob ich vielleicht diese oder jene Einstellung vergessen haben könnte.
