Can beneficial antecedents to self‐employment be detrimental to entrepreneurial performance?

We hypothesize that risk aversion, plasticity, stability, and locus of control have different effects on a person's decision to enter entrepreneurship and the person's entrepreneurial performance. Empirical results reveal that plasticity and risk tolerance have positive effects on selection but negative effects on income derived in entrepreneurship. Stability, on the other hand, deters entry but has an inversely u‐shaped relation with income. Locus of control has a positive impact on the decision but an insignificant effect on entrepreneurial income. These new insights may guide policy makers on how to help aspiring entrepreneurs overcome the negative effects of their personality traits.     

Risk, uncertainty, and option exercise

Many economic decisions can be described as an option exercise or optimal stopping problem under uncertainty. Motivated by experimental evidence such as the Ellsberg Paradox, we follow Knight (1921) and distinguish risk from uncertainty. To capture this distinction, we adopt the multiple-priors utility model. We show that the impact of ambiguity on the option exercise decision depends on the relative degrees of ambiguity about continuation payoffs and termination payoffs. Consequently, ambiguity may accelerate or delay option exercise. We apply our results to investment and exit problems, and show that the myopic NPV rule can be optimal for an agent having an extremely high degree of ambiguity aversion.     

Risk aversion in Entrepreneurship Panels: Measurement Problems and Alternative Explanations

In this study, we investigate the pitfalls associated with measuring risk aversion within studies of entrepreneurial behavior. First, we raise substantial concerns as to whether standard questions employed can be used to infer risk aversion among nascent entrepreneurs. In our work we show that the US, Canadian and Swedish panel study datasets do not offer evidence that entrepreneurs are more risk averse than non‐entrepreneurs. In fact, we show that the measurements used for risk aversion in these studies are not compatible with classic expected utility theory. Furthermore, our analysis reveals that probability weighting may even counteract the respondent's risk attitude. Therefore, inferring the respondent's risk attitude from choices in the panel study datasets can be misleading in the presence of probability weighting. We therefore suggest that alternative theories of decision making under risk, like prospect theory, are relevant and should be taken into account in future studies on entrepreneurship.

Strategic and Natural Risk in Entrepreneurship: An Experimental Study

We report on the results of experiments where participants choose between entrepreneurship and an outside option. Entrepreneurs enter a market and then make investment decisions to capture value. Payoffs depend on both strategic risk (i.e., the investments of other entrepreneurs) and natural risk (i.e., luck). Absent natural risk, participants endogenously sort themselves into entrepreneurial and safe types, and returns from the two paths converge. Adding natural risk fundamentally changes these conclusions: Here we observe excessive entry and excessive investment so that entrepreneurs earn systematically less than the outside option. These payoff differences persist even after many repetitions of the task. With a risky outside option, entry further increases and about one‐third of entrepreneurs adopt a passive strategy, investing little or nothing. Finally, we examine an environment where an individual must become an entrepreneur but chooses the stakes over which she will compete. Due to under‐entry and under‐investment in the high stakes setting, the returns gap grows to over 15 percentage points. A two‐factor model incorporating loss aversion and love of winning can rationalize these returns patterns.     

The Entrepreneurial Organization of Heterogeneous Capital*

abstract Transaction cost, property rights, and resource‐based approaches to the firm assume that assets, both tangible and intangible, are heterogeneous. Arranging these assets to minimize contractual hazards, to provide efficient investment incentives, or to exploit competitive advantage is conceived as the prime task of economic organization. None of these approaches, however, is based on a systematic theory of capital heterogeneity. In this paper we outline the approach to capital developed by the Austrian school of economics and show how Austrian capital theory provides a natural bridge between theory of entrepreneurship and the theory of the firm. We refine Austrian capital theory by defining capital heterogeneity in terms of subjectively perceived attributes, the functions, characteristics, and uses of capital assets. Such attributes are not given, but have to be created or discovered by means of entrepreneurial action. Conceiving entrepreneurship as the organization of heterogeneous capital provides new insights into the emergence, boundaries, and internal organization of the firm, and suggests testable implications about how entrepreneurship is manifested.     

Uncertain dynamics,correlation effects,and robust investment decisions

We analyze a firm׳s investment problem when the dynamics of project value and investment cost are uncertain. We provide an explicit solution using a robust method for an ambiguity averse firm taking this into account. Ambiguity aversion regarding a common risk factor impacts differently than ambiguity aversion regarding investment cost residual risk. Correlation between project value and investment cost matters; ambiguity aversion regarding common risk can decrease the investment probability only if correlation is positive. Ambiguity aversion regarding residual risk always increases the investment probability. When only project value is risky, volatility can monotonically decrease the investment threshold; this does not hold with the multiple prior method.     

Optimal Two‐part Pricing under Cost Uncertainty

This paper examines the optimal two‐part pricing under cost uncertainty. We consider a risk‐averse monopolistic firm that is subject to a cost shock to its constant marginal cost of production. The firm uses two‐part pricing to sell its output to a continuum of heterogeneous consumers. We show that the global and marginal effects of risk aversion on the firm's optimal two‐part pricing are to raise the unit price and lower the fixed payment. We further show that an increase in the fixed cost of production induces the firm to raise (lower) the unit price and lower (raise) the fixed payment under decreasing (increasing) absolute risk aversion. The firm's optimal two‐part pricing is unaffected by changes in the fixed cost under constant absolute risk aversion. Finally, we show that a mean‐preserving spread increase in cost uncertainty induces the firm to raise the unit price and lower the fixed payment under either decreasing or constant absolute risk aversion.

Heterogeneous ambiguity attitudes: a field experiment among small-scale stock investors in China

We conducted quasi-field experiments in Chinese brokerage houses to investigate how investors react to ambiguity relative to quantifiable risks and the degree of heterogeneity in these reactions. Our experiment consists of three sections; a background survey; individual self-reports of emotional states; and a series of individual portfolio choice questions involving ambiguous assets and assets with a known probability of success. We calculate an index of ambiguity aversion that controls for risk aversion through a series of simple choices and demonstrate its outside validity. We find a significant degree of heterogeneity in ambiguity attitudes and discuss some demographic or emotional factors that might contribute to this heterogeneity. We also discuss the correlation between ambiguity attitudes and risk attitudes. By conducting these experiments in China, we were able to measure the degree of ambiguity aversion among a sample of experienced and accessible investors who face ambiguous decisions on a daily basis.     

The principal-agent problem with smooth ambiguity

We study a principal-agent model in which the (effort-dependent) realisation of output levels is ambiguous, and the agent is ambiguity averse (while the principal is ambiguity neutral). We show that introducing ambiguity aversion will lower profits if the action that the principal wants to implement is the most ambiguous one, while they may increase otherwise. Regarding the design of the optimal contract, we show that under ambiguity aversion the optimal incentive scheme may not be monotone even if a natural generalization of the monotone likelihood ratio property is satisfied, and illustrate how this fact could affect the design of contracts in an applied economic context. We also find that the individual rationality constraint need not bind in the presence of ambiguity aversion unless preferences satisfy constant absolute ambiguity aversion.     

Time and the Entrepreneurial Journey: The Problems and Promise of Studying Entrepreneurship as a Process

We examine the growing disconnect between the process‐oriented conception of entrepreneurship taught in the classroom and theorized about in premier journals and the variance‐oriented conception of entrepreneurship that characterizes empirical studies of the phenomenon. We propose that a shift in inquiry from entrepreneurship as an act to entrepreneurship as a journey could facilitate process‐oriented research by initiating a dialogue about the nature of the entrepreneurial journey, when it has begun and ended, whether it might be productively subdivided into variables or events, and what if anything remains constant throughout the process. Finally, we propose that a clearer understanding of the entrepreneurial journey is necessary to distinguish the field horizontally from research on creativity and strategy, and vertically from research on more practical business functions or more abstract systems‐level concepts.     

Risk Preferences and Asset Ownership: Integrating Prospect Theory and Transaction Cost Economics

We integrate prospect theory into the discussion of Transaction Cost Economics (TCE) to illustrate how risk aversion may affect integration decisions. In particular, we argue that risk aversion creates incentives to acquire assets in situations where neither opportunism nor transaction‐specific investments are present, provided the assets in question can change in value unpredictably during their use. Our theory illustrates that risk aversion could connect opportunism, asset specificity, and uncertainty with integration decisions in the presence of incomplete contracts. Our theory complements and extends TCE by showing the role of risk aversion in integration decisions under bounded rationality and contract incompleteness.

Uncertain tax rules and futures hedging

This paper considers the optimal futures hedging decision under uncertain tax treatment. If the Corn Products (CP) rule applies, gains or losses from futures trading can offset business gains or losses. However, under the Arkansas Best (AB) doctrine, offsetting is not allowed. We show that the risk neutral firm will not trade futures contracts if the probability the CP rule prevails is small. When the probability is sufficiently large, the firm will assume an underhedge. A risk averse firm is likely to trade, even if the AB rule prevails. As long as the CP ruling is not a sure thing, the firm will engage in underhedge. The effects of average business profits, the volatility of business profits, and risk aversion on the optimal futures position are provided. Copyright © 1999 John Wiley & Sons, Ltd.     

Homeownership and mixed-asset portfolio allocations

Homeownership represents both a consumption and an investment decision for individuals. Considering the investment benefits of the home, we estimate the total returns and risk associated with the investment in single-family homes. Then, using a mean–variance utility function, we consider the impact of homeownership and mortgage loan financing on the optimal asset allocation decisions of individuals and contrast this with advice that does not include the home as part of the portfolio. While optimal portfolio weights are dependant upon both the degree of risk aversion of the individual investor and the relative importance of the home in the overall net worth picture, we show that, in general, the higher the home-to-net worth ratio, the higher the optimal portfolio allocation to stock. For most investors, including the home in the optimization decision leads to higher allocations to risky stock than suggested by traditional advice that ignores the home.     

International corruption and its impacts across entrepreneurship types

Using a large cross‐country sample, this paper examines the impact of corruption on entrepreneurial activities by uniquely addressing two questions: (a) Does the impact of corruption on entrepreneurship vary across entrepreneurship type? (b) How does the effect of corruption differ across nations with varying prevalence of entrepreneurship? Considering three dimensions of entrepreneurship, nascent entrepreneurship, new business owners, and established new business owners, results, accounting for possible two‐way causality, show that entrepreneurship is negatively affected by corruption across entrepreneurship types, with differences in the relative magnitudes of effects. This sanding effect of corruption, however, varies across the prevalence of corruption and switches to greasing for nascent entrepreneurs.     

Optimal Two‐Part Pricing under Demand Uncertainty

This paper examines the pricing behavior of a risk‐averse monopolistic firm under demand uncertainty. The firm produces a single good at a constant marginal cost. To facilitate sales, the firm uses a two‐part pricing contract that includes a membership fee and a selling price per unit. The good is sold to a continuum of heterogeneous consumers who are subject to a common demand shock. We show that the global and marginal effects of risk aversion are to push the unit price closer to the constant marginal cost and to shrink the market coverage so as to limit the firm’s risk exposure to the demand uncertainty. The more risk‐averse firm as such charges a higher membership fee to consumers. We further show that an increase in the fixed cost of production induces the firm to lower (raise) the unit price, to raise (lower) the membership fee, and to shrink (enlarge) the market coverage under decreasing (increasing) absolute risk aversion. The firm’s optimal two‐part pricing contract, however, is unaffected by changes in the fixed cost under constant absolute risk aversion. Finally, we show that a mean‐preserving‐spread increase in the demand uncertainty induces the firm to lower the unit price, to raise the membership fee, and to shrink the market coverage under either decreasing or constant absolute risk aversion. The firm’s risk preferences as such play a pivotal role in determining the optimal two‐part pricing under demand uncertainty. Copyright © 2013 John Wiley & Sons, Ltd.     

Cross-sectional implications of dynamic asset pricing with stochastic volatility and ambiguity aversion

Building on recent research that highlights the importance of macroeconomic volatility and ambiguity aversion in explaining the dynamics of stock returns, in this paper we propose a dynamic asset pricing model that simultaneously accounts for stochastic macroeconomic volatility and ambiguity, assuming that investors deal with uncertainty about the mechanics of macroeconomic fluctuations using first-release consumption and revisions to aggregate consumption on vintage data. Our results show that the proposed model captures a large fraction of the cross-sectional variation of excess returns for a wide range of market anomaly portfolios. Furthermore, while the price of risk for ambiguity is positive and significant for the vast majority of assets under study, macroeconomic volatility yields ambiguous outcomes, although it significantly increases the explanatory power of the model for specific assets. Our results suggest that macroeconomic volatility and ambiguity complement each other in explaining the cross-sectional behavior of stock returns.     

Optimal investment and reinsurance policies for an insurer with ambiguity aversion

In this paper, we study the optimal investment and reinsurance problem for an insurer based on the variance premium principle, in which three cases are considered. First, we assume that the financial market does not exist. The insurer only holds an insurance business, and the optimal reinsurance problem is studied. Subsequently, we assume that there exists a financial market with an accurately modeled risky asset. The optimal investment and reinsurance problem is investigated under these conditions. Finally, we consider the general case in which the insurer is concerned about the model ambiguity of both the insurance market and the financial market. In all three cases, the value function is set to maximize the expected utility of terminal wealth. By employing the dynamic programming principle, we derive the Hamilton–Jacobi–Bellman (HJB) equations, which are satisfied by the value functions and obtain closed-form solutions for optimal reinsurance and investment policies and the value functions in all three cases. Most interestingly, we elucidate how investment improves the insurer’s utility and find that the existence of ambiguity can significantly affect the optimal policies and value functions. We also compare the ambiguities in the two markets and find that ambiguity in the insurance market has much more significant impact on the value function than the ambiguity in the financial market. It implies that it is more valuable for insurer to precisely evaluate the insurance risk. We also provide some numerical examples and economic explanations to illustrate our results.     

Resources,Capabilities and Entrepreneurial Perceptions*

abstract We review and develop a subjectivist theory of entrepreneurship that focuses on individuals, their knowledge, resources and skills, and the processes of discovery and creativity, which constitute the heart of entrepreneurship. First, we establish the fundamental importance of subjectivity in entrepreneurial discovery and creativity. Second, we build on Penrose (1959 ) to elaborate how entrepreneurs' perceptions and personal knowledge shape a firm's subjective productive opportunity set. Third, we explain that entrepreneurial perceptions and knowledge partly originate from entrepreneurs' experiences in specific business settings such as the firm, the management team, and the industry. Fourth, we highlight the causal connections between subjectivity in entrepreneurship and observed heterogeneity in firm‐level economic performance. Lastly, we suggest directions for further advancing a subjectivist resource‐based approach to future entrepreneurship research.     

System‐Spanning Values Work and Entrepreneurial Growth in Family Firms

Culture and values are key drivers of corporate entrepreneurship in early stages of family firm development, but value conflicts often arise over time that progressively inhibit their entrepreneurial efforts. How can family firms reconcile conflicting values to sustain corporate entrepreneurship over time? Our 45‐year longitudinal case study of a large global family firm shows that family business leaders’ practices of invoking and flexibly using family and business values were crucial to achieve sustained entrepreneurial behaviour and growth over an extended period of time. We theorize these efforts as system‐spanning values work enfolding through specific family, business, and temporal mechanisms. By identifying and elucidating three types of values work (i.e., rooting, revitalizing, and spreading), our study advances current understanding of the micro‐foundations underpinning the relationship between values and entrepreneurship in family firms.     

Rationalizing investors’ choices

Assuming that agents’ preferences satisfy first-order stochastic dominance, we show how the Expected Utility paradigm can rationalize all optimal investment choices: the optimal investment strategy in any behavioral law-invariant (state-independent) setting corresponds to the optimum for an expected utility maximizer with an explicitly derived concave non-decreasing utility function. This result enables us to infer the utility and risk aversion of agents from their investment choice in a non-parametric way. We relate the property of decreasing absolute risk aversion (DARA) to distributional properties of the terminal wealth and of the financial market. Specifically, we show that DARA is equivalent to a demand for a terminal wealth that has more spread than the opposite of the log pricing kernel at the investment horizon.
