This paper gives a relatively simple, well behaved solution to the problem of many instruments in heteroskedastic data. Such settings are common in microeconometric applications where many instruments are used to improve efficiency and allowance for heteroskedasticity is generally important. The...

It is often suggested that incentive schemes under moral hazard can be gamed by an agent with superior knowledge of the environment, and that deliberate lack of transparency about the incentive scheme can reduce gaming.  We formally investigate these arguments.  Ambiguous incentive schemes...

We propose a probabilistic numerical algorithm to solve Backward Stochastic Differential Equations (BSDEs) with nonnegative jumps, a class of BSDEs introduced in [9] for representing fully nonlinear HJB equations. In particular, this allows us to numerically solve stochastic control problems...

We study the contractual interaction between the fathers of a prospective groom and a prospective bride in a traditional society. Based on his valuation of the groom, the bride's father approaches the groom's father with an offer of marriage. The groom's father does not know the quality of the...

In 2009 the Australian government delivered approximately $8 billion in direct payments to households. These payments were preannounced and randomly allocated to households based on postal codes over a 5-week period. We exploit this random allocation to estimate the causal response of...
