摘要：Motivated by the growing discussion on the resemblance of multilevel marketing schemes to pyramid scams, we compare the two phenomena based on their underlying compensation structures. We show that a company can design a pyramid scam to exploit a network of agents with coarse beliefs and that this requires the company to charge the participants a license fee and pay them a recruitment commission for each of the people that they recruit and that their recruits recruit. We characterize the schem...

摘要：We extend the theory of optimal redistributive taxation to economies with an informal sector. In particular, in our model, workers can supply labor simultaneously to the formal and the informal sectors, which we call moonlighting. The optimal tax formula contains two novel terms capturing informality responses on an intensive and an extensive margin. Both terms decrease the optimal tax rates. We estimate the model with Colombian data and find that informality strongly reduces tax rates at all ...

摘要：The founder of a start-up (principal) who has a project with uncertain returns must retain and incentivize an agent using promise of future payments and information gathering. The agent's effort incrementally advances production and such advance is a prerequisite for gathering new information. The principal decides how much information to gather based on these incremental advancements. The principal faces cash constraints. The agent's outside option is large relative to his effort cost. Equili...

摘要：This paper characterizes those preferences over bounded infinite utility streams that satisfy the time value of money principle and an additivity property, and the subset of these preferences that, in addition, are either impatient or patient. Based on this characterization, the paper introduces a concept of optimization that is robust to a small imprecision in the specification of the preference, and proves that the set of feasible streams of payoffs of a finite Markov decision process admits...

摘要：What are the value and form of optimal persuasion when information can be generated only slowly? We study this question in a dynamic model in which a sender provides public information over time subject to a graduality constraint, and a decision maker takes an action in each period. Using a novel viscosity dynamic programming principle, we characterize the sender's equilibrium value function and information provision. We show that the graduality constraint inhibits information provision relati...

摘要：A sender sells an object of unknown quality to a receiver who pays his expected value for it. Sender and receiver might hold different priors over quality. The sender commits to a monotone categorization of quality. We characterize the sender's optimal monotone categorization, the optimality of full pooling or full separation, and make precise a sense in which pooling is dominant relative to separation. As an application, we study the design of a grading scheme by an educational institution th...

摘要：This paper shows that in some axioms regarding the mixture of random variables, the requirement that the conclusions hold for all values of the mixture parameter can be weakened by requiring the existence of only one nontrivial value of the parameter, which need not be fixed. This is the case for the independence, betweenness, and mixture symmetry axioms. Unlike the standard axioms, these weaker versions cannot be refuted by experimental methods.

摘要：Matchings in a market may have varying degrees of compromise from efficiency, fairness, and or stability. A distance function allows to quantify such concepts or the (dis)similarity between any two matchings. There are a few attempts to propose such functions; however, these are tailored for specific applications and ignore the individual preferences completely. In this paper, we construct a normative framework to quantify the difference between outcomes of market mechanisms in matching market...

摘要：In this paper, we study the conditions under which termination is a useful incentive device in the canonical dynamic principal-agent moral hazard model of Sannikov (2008). We find that temporary suspension of the agent after poor performance dominates termination if the principal's outside option is low and the agent's outside option is moderate. In suspension, the agent performs tasks free of moral hazard and receives no compensation, which rebuilds his skin in the game and allows for incenti...

摘要：This paper develops an integer programming approach to two-sided many-to-one matching by investigating stable integral matchings of a fictitious market where each worker is divisible. We show that a stable matching exists in a discrete matching market when the firms' preference profile satisfies a total unimodularity condition that is compatible with various forms of complementarities. We provide a class of firms' preference profiles that satisfy this condition.
