There is a growing body of evidence that many entrepreneurs seem to enter and persist in entrepreneurship despite earning low risk-adjusted returns. This has lead to attempts to provide explanations—using both standard economic theory and behavioral economics—for why certain individuals may be attracted to such an apparently unprofitable activity. Drawing on research in behavioral economics, in the sections that follow, we review three sets of possible interpretations for understanding the empirical facts related to the entry into, and persistence in, entrepreneurship. Differences in risk aversion provide a plausible and intuitive interpretation of entrepreneurial activity. In addition, a growing literature has begun to highlight the potential importance of overconfidence in driving entrepreneurial outcomes. Such a mechanism may appear at face value to work like a lower level of risk aversion, but there are clear conceptual differences—in particular, overconfidence likely arises from behavioral biases and misperceptions of probability distributions. Finally, nonpecuniary taste-based factors may be important in motivating both the decisions to enter into and to persist in entrepreneurship.
This paper explores the limitations of intention-based social preferences as an explanation of gift-exchange between a firm and a worker. In a framework with one self-interested and one reciprocal player, gift-giving never arises in equilibrium. Instead, any equilibrium in a large class of multistage games must involve mutually unkind behavior of both players. Besides gift-exchange, this class of games also includes moral hazard models and the rotten kid framework. Even though equilibrium behavior may appear positively reciprocal in some of these games, the self-interested player never benefits from reciprocity. We discuss the relation of these results to the theoretical and empirical literature on gift-exchange in employment relations.
To examine the impact of globalization on managerial remuneration, we consider a matching model where firms compete both in the product market and in the managerial market. We show that globalization, i.e., the simultaneous integration of product markets and managerial pools, leads to an increase in the heterogeneity of managerial salaries. Typically, while the most able managers obtain a wage increase, less able managers are faced with a reduction in wages. Hence our model is consistent with the increasing heterogeneity of CEO remuneration that has been observed in the last few decades.
An increasingly influential "technological-discontinuity" paradigm suggests that IT-induced technological changes are rapidly raising productivity while making workers redundant. This paper explores the evidence for this view among the IT-using US manufacturing industries. There is some limited support for more rapid productivity growth in IT-intensive industries depending on the exact measures, though not since the late 1990s. Most challenging to this paradigm, and to our expectations, is that output contracts in IT-intensive industries relative to the rest of manufacturing. Productivity increases, when detectable, result from the even faster declines in employment.
China wird sich nicht von der EU abwenden, nur weil es einen Gasdeal mit Russland schließt. Das sagt der italienische Ökonom und Chinakenner Fabrizio Zilibotti. Interview: Axel Hansen
Wenn die EU gerettet werden soll, muss im Spitzenpersonal eine «Verschrottung» à la Renzi stattfinden. Nun ist Mut gefragt, und Deutschland muss die Führung übernehmen. Ein Kommentar von Fabrizio Zilibotti.
We discuss the two-way link between culture and economic growth. We present a model of endogenous technical change where growth is driven by the innovative activity of entrepreneurs. Entrepreneurship is risky and requires investments that affect the steepness of the lifetime consumption profile. As a consequence, the occupational choice of entrepreneurship hinges on risk tolerance and patience. Parents expecting their children to become entrepreneurs have an incentive to instill these two values in their children. Cultural transmission is Beckerian, i.e., parents are driven by the desire to maximize their children's happiness. We also consider, in an extension, a paternalistic motive for preference transmission. The growth rate of the economy depends on the fraction of the population choosing an entrepreneurial career. How many entrepreneurs there are in a society hinges, in turn, on parental investments in children's patience and risk tolerance. There can be multiple balanced-growth paths, where in faster-growing countries more people exhibit an "entrepreneurial spirit." We discuss applications of models of endogenous preferences to the analysis of socio-economic transformations, such as the British Industrial Revolution. We also discuss empirical studies documenting the importance of culture and preference heterogeneity
for economic growth.
This paper analyzes two-stage rank-order tournaments. A principal decides (i) how to spread prize money across the two periods, (ii) how to weigh performance in the two periods when awarding the second-period prize, and (iii) whether to reveal performance after the first period. The information revelation policy depends exclusively on properties of the effort cost function. The principal always puts a positive weight on first-period performance in the second period. The size of the weight and the optimal prizes depend on properties of the observation error distribution; they should be chosen so as to strike a balance between the competitiveness of first- and second-period tournaments. In particular, the principal sets no first-period prize unless the observations in period one are considerably more precise than in period two.
We construct an extensive form game that captures competitive markets with adverse selection. It allows firms to offer any finite set of contracts, so that cross-subsidization is not ruled out. Moreover, firms can withdraw from the market after initial contract offers have been observed. We show that a subgame perfect equilibrium always exists. In fact, when withdrawal is costless, the set of equilibrium outcomes may correspond to the entire set of feasible contracts. We then focus on robust equilibria that continue to exist for small withdrawal costs. We show that the Miyazaki–Wilson contracts are the unique robust equilibrium outcome.
