We study the effects that the Maastricht Treaty, the creation of the ECB, and the Euro changeover had on the dynamics of European business cycles using a panel VAR and data from 10 European countries—seven from the Euro area and three outside of it. There are changes in the features of...

Under the hypothesis that aggregate U.S. consumption is random and, more importantly, viewed as ambiguous by consumers, we examine the implications for asset prices and for how consumption fluctuations influence consumer welfare. We consider a simple, Mehra–Prescott-style endowment economy...

This paper studies counterfeiting of bank notes in a monetary model under competitive search. The application of the refinement scheme proposed by Guerrieri et al. (2010) shows that there is no equilibrium with counterfeiting. However, due to the entry margin, counterfeiting poses a threat to...

This paper shows that non-convex costs of financial adjustment are quantitatively relevant for explaining firm dynamics. First, empirically, financial activity is lumpy, more than investment activity. Second, non-convex costs are necessary, in the context of a dynamic investment and financing...

We investigate the effect of monetary policy on stock market bubbles and trading behavior in experimental asset markets. We introduce the possibility of investing in interest bearing bonds to the widely used laboratory asset market design of Smith et al. (1988). Treatment groups face a variable...

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...

Governments are confronted with the growing realization that they face fiscal limits on the size of debt and deficits relative to GDP. These fiscal limits invalidate Bohn's criterion for fiscal sustainability, which allows explosive debt relative to GDP, eventually violating any fiscal limit. We...

We explore a New Keynesian Model with diverse beliefs and study the aggregation problems in the log-linearized economy. We show the solution of these problems depend upon the belief structure. Agents' beliefs are described by individual state variables and satisfy three Rationality Axioms,...

In a continuous time life cycle model of consumption with an uncertain lifetime, we use a non-parametric specification of rank-dependent utility theory to characterize the preferences of the agent. We prove that time consistency holds for a subclass of probability-weighting function, providing...

In standard models of experimentation, the costs of project development consist of (a) the direct cost of running trials as well as (b) the implicit opportunity cost of leaving alternative projects idle. Another natural type of experimentation cost, the cost of holding on to the option of...
