ROLE OF RELATIVE AND ABSOLUTE PERFORMANCE EVALUATIONS IN INTERGROUP COMPETITION

We investigate the moral hazard problem in which a principal delegates multiple tasks to multiple workers. The principal imperfectly monitors their action choices by observing the public signals that are correlated with each other through a macro shock. He divides the workers into two groups and makes them compete with each other. We show that when the number of tasks is sufficiently large, relative performance evaluation between the groups accompanied by absolute performance evaluation results in eliminating unwanted equilibria. In this case, any approximate Nash equilibrium nearly induces the first‐best allocation.     

Innovation management in organizations

This paper poses the question of how a firm should optimally choose both its organization and its compensation in the pursuit of innovation. One key result is that incentive pay arises as a robust instrument of innovation management both with and without delegation, although in the present model its primary purpose is not to elicit more effort for the creation of new ideas, but to ensure that new ideas are implemented if and only if this is efficient. While without delegation, the firm may “underinvest” in innovation, with delegation the opposite bias may arise as new ideas may be implemented too often (“overinvestment”). The optimal organizational choice trades off these two biases.     

A general equilibrium analysis of software development: Implications of copyright protection and contract enforcement

We develop a general equilibrium model to study the implications of a legal environment on the organization of software production. We show that contract enforcement determines the organizational mode (i.e., in-house versus outsourcing) of customized software development while copyright protection affects both packaged software as well as customized software development. We obtain some testable results: when copyright protection is weak, only customized software will be developed; when copyright protection is strong, both customized software and packaged software will be developed; environment changes in one software market affect the equilibrium in the other software market.     

Collusion and the organization of delegated expertise

We study the optimal design of incentive contracts for experts in different collusion environments, and explore implications for the organization of delegated expertise. We consider a principal relying on experts to gather and report two signals about a project's value. The principal can have a single expert gather both signals or two experts gather one signal each. We show that absent collusion, the multiexpert organization dominates the single expert organization. However, this ranking is reversed when the experts can collude among themselves (horizontal collusion) and with the principal (vertical collusion).     

Can Agents Be Better Off with Pay Caps?

A popular way to discipline the managers of companies or banks that got into trouble during the recent financial crisis has been to impose caps on managers' pay. Using a small extension of the standard principal–agent model, we argue that pay caps might serve the opposite purpose, because the agent might be better off with a pay cap. Specifically, we show that, given a fixed effort level to be implemented, the agent's expected utility can be decreasing in an upper bound for the agent's reward. The effect of pay caps on the general structure of optimal incentive contracts is also characterized. While an improvement of contracting information always helps the principal, it might increase or decrease the marginal cost of imposing pay caps.     

Risk Taking in Asymmetric Tournaments

Abstract. A tournament is examined in which two agents with different abilities choose efforts as well as risks. According to the previous literature, the more (less) able agent should choose a low (high) risk strategy, because the first one does not want to imperil his favorable position, whereas the last one can only gain by increasing risk. We show that this is not necessarily true. Risk taking affects equilibrium efforts as well as winning probabilities. Depending on both effects diverse equilibria are possible. For example, the low and the high ability agent may both choose high risks or both choose low risks.     

Unemployment insurance with hidden savings

This paper studies the design of unemployment insurance when neither the searching effort nor the savings of an unemployed agent can be monitored. If the principal could monitor the savings, the optimal policy would leave the agent savings-constrained. With a constant absolute risk-aversion (CARA) utility function, we obtain a closed form solution of the optimal contract. Under the optimal contract, the agent is neither saving nor borrowing constrained. Counter-intuitively, his consumption declines faster than implied by Hopenhayn and Nicolini (1997) [1]. The efficient allocation can be implemented by an increasing benefit during unemployment and a constant tax during employment.     

How does employment protection legislation influence hiring and firing decisions by the smallest firms?

This paper examines the impact of employment protection legislation (EPL) on hiring decisions by own-account workers and firing decisions by very small firms (one to four employees). Using data from the EU-15 countries, our results show that the strictness of employment protection legislation is negatively related to both these types of decisions, and hence, to labour mobility among the smallest firms. This new evidence may be useful for governments aiming to create a more enabling macro-environment for employment and productivity growth.     

Public procurement in times of crisis: The bundling decision reconsidered

The government wants two tasks to be performed. In each task, unobservable effort can be exerted by a wealth-constrained private contractor. If the government faces no binding budget constraints, it is optimal to bundle the tasks. The contractor in charge of both tasks then gets a bonus payment if and only if both tasks are successful. Yet, if the government has only a limited budget, it may be optimal to separate the tasks, so that there are two contractors each in charge of one task. In this case, high efforts in both tasks can be implemented with smaller bonus payments.     

Stochastic mechanisms in settings without monetary transfers: The regular case

We analyze relative performance of stochastic and deterministic mechanisms in an environment that has been extensively studied in the literature on communication (e.g., [Vincent P. Crawford, Joel Sobel, Strategic information transmission, Econometrica 50 (6) (1982) 1431-1451]) and optimal delegation (e.g., [Bengt Holmström, On the theory of delegation, in: M. Boyer, R.E. Kihlstrom (Eds.), Bayesian Models in Economic Theory, North-Holland, 1984, pp. 115-141]): a principal-agent model with hidden information, no monetary transfers, and single-peaked preferences. We demonstrate that under the common assumption of quadratic payoffs and a certain regularity condition on the distribution of private information and the agent's bias, the optimal mechanism is deterministic. We also provide an explicit characterization of this mechanism.     

Multinational companies, backward linkages, and labour demand elasticities

Abstract .  This paper investigates the link between nationality of ownership and wage elasticities of labour demand at the level of the plant. In particular, we examine whether labour demand in multinationals becomes less elastic with respect to the wage if the plant has backward linkages with the local economy. Our empirical evidence, based on a rich plant level dataset, shows that the extent of local linkages does indeed generally reduce the wage elasticity of labour demand. This result is economically important and holds for a number of different specifications.     

Unemployment Benefits and Entrepreneurship

Several recent empirical papers show that unemployment benefits crowd out nascent entrepreneurs. In the present paper provide theoretical support in favour of this interesting result. Over fairly general preference patterns we obtain a measure of the opportunity cost of entrepreneurs in the presence of unemployment benefits and derive conditions under which potential entrepreneurs suffer as unemployment benefits rise. We formulate a clear transmission mechanism in the labour market that links unemployment benefits to occupational choice for a group of risk‐averse individuals.     

Optimal ownership of public goods reconsidered

Consider a non-governmental organization (NGO) that can invest in a public good. Should the government or the NGO own the public project? In an incomplete contracting framework with split-the-difference bargaining, Besley and Ghatak (2001) argue that the party who values the public good most should be the owner. We demonstrate the robustness of their insight when the split-the-difference rule is replaced by the deal-me-out solution. Our finding is in contrast to the private good results of Chiu (1998) and De Meza and Lockwood (1998), who show that the optimal ownership structure crucially depends on whether the split-the-difference rule or the deal-me-out solution is used.     

Managerial incentives and collusive behavior

I characterize the effects of empirically observed managerial incentives on long-run oligopolistic competition. When managers have a preference for smooth time-paths of profits - as revealed by the empirical literature on “income smoothing” - manager-led firms can sustain collusive agreements at lower discount factors. Capped bonus plans and incumbency rents with termination threats make collusion supportable at any discount factor, independent of contracts' duration. When managers have these preferences/incentives and demand fluctuates, “price wars during booms” need not occur: the most collusive price may then be pro-cyclical.     

The impact of Sunday shopping on employment and hours of work in the retail industry: Evidence from Canada

Between 1980 and 1998 every Canadian province passed legislation that in some way relaxed restrictions on Sunday shopping. This study exploits the variation in deregulation dates between provinces to identify how retail employers adjust employment and hours of work when deciding to open on Sundays. A major complication of this analysis is to first determine for which provinces the deregulation dates are useful indicators of increases in Sunday store openings. This paper uses a unique trading-day regression approach to identify these provinces and then uses aggregate data from the selected provinces to estimate a simple dynamic labour demand model that allows employment and hours to be imperfect substitutes in production. The results suggest that retailers’ needs for Sunday labour were disproportionately satisfied through increases in employment levels. Comparison of the estimates at three levels of the retail industry suggests that the employment and hours gains were larger among general merchandise stores than among more specialized retail establishments and relatively modest at the aggregate retail industry level. In addition, despite evidence of an immediate shortfall in the employment level below the long-run optimal level, the results suggest that firms were unable to compensate by temporarily increasing the hours of their existing employees.
