This paper studies optimal monetary policy in a DSGE model with supply side strategic complementarity, as arising from oligopolistic competition, and nominal rigidities. Firms' oligopolistic rents induce inefficient fluctuations through both, intra-temporal and intertemporal time-varying wedges....

Recent estimates of the output Euler equation for the United States indicate that the elasticity of aggregate demand to interest rates is not significantly different from zero. We first argue that this result may hide a structural break: the estimated elasticity is a convolution of two...

This paper presents a monetary model in which interbank markets have limited commitment to contracts. Limited commitment reduces the proportion of assets that can be used as collateral, and thus banks with high liquidity demands face borrowing constraints in interbank markets. These constraints...

This paper models the gold standard as a state contingent commitment technology that is only feasible during peace. Monetary policy during war, when the gold convertibility rule is suspended, can still be credible, if the policymaker's plan is to resume the gold standard in the future. The DSGE...

The rate of information diffusion and, consequently, price discovery are conditional not only upon the design of the market microstructure but also the informational structure. This paper presents a market microstructure model showing that an increasing number of information hierarchies among...

The presence of excess covariance in financial price returns is an accepted empirical fact: the price dynamics of financial assets tend to be more correlated than their fundamentals would justify. We advance an explanation of this fact based on an intertemporal equilibrium multi-assets model of...

This paper formulates a continuous-time information transmission model in which an altruistic sender privately observes a stochastic state variable, and incurs a communication cost when she broadcasts a message. We characterize the sender's optimal announcement strategy using an ordinary...

This paper explores the link between the leverage of the US financial sector, of households and of non-financial businesses, and real activity. We document that leverage is negatively correlated with the future growth of real activity, and positively linked to the conditional volatility of...

We propose an evolutionary analysis of a voting game where citizens have a preference for conformism that adds to the instrumental preference for the electoral outcome. Multiple equilibria arise, and some generate high turnout. Simulations of best response dynamics show that high turnout is...

Numerous optimal control models analyzed in economics are formulated as discounted infinite time horizon problems, where the defining functions are nonlinear as well in the states as in the controls. As a consequence solutions can often only be found numerically. Moreover, the long run optimal...
