We develop a simple and intuitive approach for analytically deriving unconditionally optimal (UO) policies, a topic of enduring interest in optimal monetary policy analysis. The approach can be employed to both general linear-quadratic problems and to the underlying non-linear environments. We...

Standard consumption-investment theory predicts counter-cyclical (pro-cyclical) behavior of household (corporate) credit whereby households' consumption smoothing and firms' investment motives are aligned. Counter to the theoretical symbiosis consistent with U.S. data, we demonstrate not only in...

The Greek economy experienced a boom until 2007, followed by a prolonged depression resulting in a 25 percent shortfall of GDP by 2016. Informed by a detailed analysis of macroeconomic patterns in Greece, we estimate a rich dynamic general equilibrium model to assess quantitatively the sources...

From 1960-2009, the U.S. current account balance has tended to decline during expansions and improve in recessions. We argue that trend shocks to productivity can help explain the countercyclical U.S. current account. Our framework is a two-country, two-good real business cycle (RBC) model in...

This paper uses a Bayesian approach to estimate a standard international real business cycle model augmented with preferences with zero wealth-effect, variable capacity utilization and investment adjustment costs. First, I find that the bulk of fluctuations in country-specific outputs,...

This paper studies the domestic and international effects of national bank market integration in a two-country, dynamic, stochastic, general equilibrium model with endogenous producer entry. Integration of banking across localities reduces the degree of local monopoly power of financial...

Credit constraints that link a private agent’s debt to market-determined prices embody a credit externality that drives a wedge between competitive and constrained socially optimal equilibria, inducing private agents to overborrow. The externality arises because agents fail to internalize the...

This article proposes Minsky's financial instability hypothesis (FIH) as a theoretical underpinning for a three-regime business cycles model. Further, it is argued that the development of the FIH for open, developing economies (FIH-ODE) provides a better understanding of the performance of...

To what extent is the international business cycle affected by the fact that an essential input (oil) is traded on the world market? We quantify the contribution of oil by setting up a model with separate shocks to efficiencies of capital/labor and oil, as well as global shocks to the oil...
