Riordan and Sappington (JET, 1988) show that in an agency relationship in which the agent's type is correlated with a public ex post signal, the principal may attain first best (full surplus extraction and efficient output levels) if the agent is faced with a lottery such that each type is...

We examine the combined effects of asymmetric taxation and limited liability on optimal risk taking of investors. Given an optimal risk level in the pre-tax case under full liability, loss-offset restrictions reduce, and limited liability enhances the incentives for taking risk. For every degree...

We analyze a multitasking model with a verifiable routine task and a skill-dependent activity characterized by moral hazard. Contracts negotiated by firm/employee pairs follow from Nash bargaining. High- and low-skilled employees specialize, intermediate productivity employees perform both...

Loss aversion, risk aversion, and the probability weighting function (PWF) are three central concepts in explaining decisionmaking under risk. I examine interlinkages between these concepts in a model of decisionmaking that allows for loss averse/tolerant stochastic reference dependence and...

We consider income-source-dependent tax evasion and show that this is a generalization of the well-known endowment effect. We show that loss aversion, moral costs, mental accounting, and risk preferences play a key role in explaining key features of source-dependent tax evasion. We provide...

We derive the optimal contract between a principal and a liquidity-constrained agent in a stochastically repeated environment. The contract comprises a court-enforceable explicit bonus rule and an implicit fixed salary promise that must be self-enforcing. Since the agent's rent increases with...

Civil servants have a bad reputation of being lazy. However, citizens' personal experiences with civil servants appear to be significantly better. We develop a model of an economy in which workers differ in laziness and in public service motivation, and characterise optimal incentive contracts...

The paper develops an axiomatic framework for rational decision making. The von Neumann-Morgenstern axioms give rise to a richer risk attitude than that captured in the standard discounted expected utility model. I derive three models that permit a more comprehensive risk evaluation. These...

We introduce a simple, easy to implement instrument for jointly eliciting risk and ambiguity attitudes. Using this instrument, we structurally estimate a two-parameter model of preferences. Our findings indicate that ambiguity aversion is significantly overstated when risk neutrality is assumed....

Evidence from hypothetical scenarios strongly suggests the existence of a sunk cost bias, the tendency to ‘throw good money after bad money.’ However, the few studies using incentives are inconclusive. In addition, evidence on potential psychological channels underlying such a bias is...
