The majority of results in the literature on general equilibrium are not for an economy (i.e. given an endowment and preferences), but rather, for a set of economies (i.e. a set of endowments given preferences). Therefore, we argue that the most appropriate robustness result requires perturbing...

We argue that when fiscal policy is endogenously determined, the incentives of redistributive politics associated with its formulation can endogenously add to the uncertainty and volatility that an economy faces. In particular, small shocks may get translated into large fluctuations. Our...

We examine the roles and values of honesty and advocacy in communication by studying two closely-related variants of the standard cheap-talk game. In the honesty model, the sender is behavioral and honestly reveals the state with a positive probability. In the advocacy model, the sender is...

We study and compare the behavioral consequences of honesty and white lie in communication. An honest agent always recommends the ex post optimal policy to the principal, while a white liar may manipulate information but only for the sake of the principal. We identify the effects of honesty and...

We study the problem of efficient auction design in environments with interdependent values, under arbitrary common knowledge assumptions. We propose a simple mechanism and show that, under a rather mild condition, it "robustly" achieves efficiency. Our mechanism consists in a standard Vickrey...

Dynamic factor models and dynamic stochastic general equilibrium (DSGE) models are widely used for empirical research in macroeconomics. The empirical factor literature argues that the co-movement of large panels of macroeconomic and financial data can be captured by relatively few common...

When estimating DSGE models, the number of observable economic variables is usually kept small, and it is conveniently assumed that DSGE model variables are perfectly measured by a single data series. Building upon Boivin and Giannoni (2006), we relax these two assumptions and estimate a fairly...
