This paper explores the macroeconomics of fiscal austerity and deflation in an economy with public debt. A binding budget deficit cap destabilizes the economy by turning the government budget into an automatic destabilizer. Public debt helps maintain AD in the presence of deflation because...

The paper shows how aggregate AS-AD can be derived within the standard neoclassical dynamic setting known as the Ramsey-Cass- Koopmans (RCK) model. AS-AD is the stationary equilibrium of the deterministic dynamic general equilibrium framework. The derivation builds a permanent income type...

This paper assesses whether labor market frictions, in the form of searching and matching, can help explain movements in the labor wedge - the gap between the marginal rate of substitution (MRS) and the marginal productivity of labor in a perfectly competitive business cycle model. Results...

Traditionally, observed fluctuations in aggregate economic time series have been mainly modeled as being the result of exogenous disturbances. A better understanding of macroeconomic phenomena, however, surely requires looking directly at the relations between variables that may trigger...

The Great Recession, and the fiscal response to it, has revived interest in the size of fiscal multipliers. Standard business cycle models have difficulties generating multipliers greater than one. And they also fail to produce any significant asymmetry in the size of the multipliers over the...

Countries with weaker domestic institutions hold fewer foreign assets and exhibit concentrated corporate ownership. An equilibrium business cycle model of international capital flows with corporate governance frictions between outside investors and insiders explains both phenomena. Investment...

Which are the main frictions and driving forces of business cycle dynamics in a small open economy? To answer this question we extend what is becoming the standard new Keynesian model in three dimensions. First, we incorporate frictions in the financing of the capital stock. Second, we model...
