I study the welfare implications of size-dependent firm regulation policies (SDPs) in the presence of entrepreneurial risks. Although SDP has been considered a source of misallocation, I show that, once entrepreneurial risks are taken into account, SDP can improve efficiency. Quantitatively, I...

We analyze a dynamic principal-agent problem in which the agent's effort in each period has strong persistent effects. We show that a simple contract, where the reward depends only on the final outcome, is explained as the optimal contract derived in the principal's optimization problem. The...

The marketing literature refers to the concept of brand capital and provides empirical evidence that firms with a large stock of well-established brands have an advantage in introducing new products. This paper develops a theory of brand extension as a mechanism for informational leverage in...

In the model there are two types of financial auditors with identical technology, one of which is endowed with a prior reputation for honesty. We characterize conditions under which there exists a 'two-tier equilibrium' in which 'reputable' auditors refuse bribes offered by clients for fear of...

In dynamic principal-agent relationships, it is sometimes observed that the agent's reward depends only on the final outcome. For example, a student's grade in a course quite often depends only on the final exam score, where the performance in the problem sets and the mid-term exam is ignored....

The purpose of this paper is to investigate contract renegotiation in multi-agent situations where risk averse agents negotiate a contract offer to the principal after they observed a common, unverifiable perfect signal about their actions. Renegotiation gives the agents gains from mutual insurance.

The purpose of this paper is to examine how tasks should be allocated in a simple hierarchy consisting of an organizational designer and subordinates, in the framework of a principal-agent relationship with moral hazard.

The purpose of the paper is to investigate how side track (or collusion) among agents affects the principal's welfare in a hidden action model. We assume that the agent's actions are mutually observable but not contradictable among them and hence direct coordination of actions via side...

This paper reexamines the paradoxical aspect of the electronic mail game (Rubinstein, 1989). The electronic mail game is a coordination game with payoff uncertainty. At a Bayesian Nash equilibrium of the game, players cannot achieve the desired coordination of actions even when a high order of...

Previous theoretical researches show that learning from good performers yields intense competition and results in the low profitability of firms. These researchers do not take into account differentiation strategies being referred as a useful strategic tool to mitigate competition. We introduce...
