Empirical studies suggest that fluctuations in the level and volatility of the world interest rate (as measured by the US treasury bill rate) affect sovereign spreads in emerging economies. We incorporate an estimated time-varying process for the world interest rate (with both level and...

We uncover new facts: U.S. banks countercyclically vary the ratio of charge-offs to defaulted loans (COD). The variance of this ratio is roughly 15 times larger than that of GDP. Canonical financial accelerator models cannot explain this variance. We develop an expression for the wedge between...

Sovereign spreads and the level of bureaucratic diversion of government spending vary widely across emerging economies and are correlated with each other. We build a sovereign default model where the government is constrained to use corrupt bureaucrats to deliver public goods and services in...

A major unresolved issue in business cycle theory is the construction of an endogenous propagation mechanism capable of capturing the amount of persistence displayed in the data. In this paper we explore the quantitative implications of one propagation mechanism: learning by doing. Estimation of...
