Business cycles reflect changes over time in the amount of trade between individuals. In this paper we show that incorporating explicitly intra-temporal gains from trade between individuals into a macroeconomic model can provide new insight into the potential mechanisms driving economic...

This paper builds a dynamic general equilibrium macro-finance model with two types of borrowers: entrepreneurs who want to produce and gamblers who want to play a lottery. It links central bank's interest rate policy to expected cash flows of both types. This link enables us to study how the...

When the zero lower bound on nominal interest rates binds, monetary policy cannot provide appropriate stimulus. We show that in the standard New Keynesian model, tax policy can deliver such stimulus at no cost and in a time-consistent manner. There is no need to use inefficient policies such as...

According to conventional wisdom, fiscal policy is more effective under a fixed than under a flexible exchange rate regime. In this paper we reconsider the transmission of shocks to government spending across these regimes within a standard new-Keynesian model of a small open economy. Because of...

Using indirect inference based on a VAR we confront US data from 1972 to 2007 with a standard New Keynesian model in which an optimal timeless policy is substituted for a Taylor rule. We find the model explains the data both for the Great Acceleration and the Great Moderation. The implication is...

This paper develops a dynamic stochastic general equilibrium model with rational inattention. Households and decision-makers in firms have limited attention and decide how to allocate their attention. The paper studies the implications of rational inattention for business cycle dynamics. Impulse...

Currency crisis literature offers a broad area of research regarding the causes and impacts of the phenomenon. The literature recently focuses on the appropriate policy measures in the aftermath of a currency crisis; however the studies do not gather around a robust answer regarding the...

This paper uses a DSGE model to examine the effects of an expansion in government spending in a liquidity trap. The spending multiplier can be much larger than in the normal situation if the liquidity trap is very prolonged, and the budgetary costs minimal. But given this "fiscal free lunch," it...

This paper is an attempt to provide an updated assessment of what we know and what do not know about the impact of monetary policy on the economy and what implications follow for the conduct of monetary policy in today's world. Firstly, we discuss the conditions under which monetary policy can...

In this paper we show that the delegation of monetary policy to an independent and more conservative central banker is an optimal policy in an international context with monetary spillovers between countries, even in the absence of time inconsistency (credibility) issues. We also study the...
