How large are welfare costs related to economic aggregate fluctuations is a topic of great concern among economists at least since Robert Lucas’ well-known and thoughtprovoking exercise in the late 1980s. Our analysis assesses the magnitude of such costs for 11 countries in South America...

Extant estimates of the welfare cost of business cycles suggest that this cost is quite low and might well be minuscule. Those estimates are based on consumption data for the United States as a whole. The volatility of aggregate consumption, however, is much stronger at the state level. We argue...

Can active Taylor rules (i.e. monetary rules where the nominal interest rate responds more than proportionally to inflation) deliver global equilibrium uniqueness in small open economies? By studying the local and global dynamics of a standard small open economy we point out the misleading...

This paper examines the relationship of business cycles, the terms of trade and Tobin's q using a three-sector dynamic stochastic general equilibrium model for a small open economy. Results show that terms of trade shocks account for half of actual volatility of GDP and stock market indices for...

This paper considers a factor model in which independent component analysis (ICA) is employed to construct common factors out of a large number of macroeconomic time series. The ICA has been regarded as a better method to separate unobserved sources that are statistically independent to each...

When univariate methods are applied to real exchange rates, point estimates of autoregressive coefficients typically imply very slow rates of mean reversion. Rogoff (1996) discusses that the remarkable consensus of 3-5 year half-lives of purchasing power parity (PPP) deviations is found among...

Chile put into place broad free trade agreements (FTAs) with its two major trading partners: the EU (effective 2003) and the US (effective 2004). This paper quanti- fies their economic effects for the Chilean economy, stemming from the conventional trade components (lower tariffs and higher...

In spite of the concerns about "twin deficits" (fiscal and current account deficits) for the U.S., empirical evidence suggests that “twin divergence” is a more regular feature of the data: when the fiscal accounts worsen, the current account improves and vice versa. We thus study empirically...

It is now widely understood how to obtain first-order accurate approximations to the solution to a dynamic, stochastic general equilibrium model (DSGE model). Such solutions are fairly easy to construct and useful for a wide variety of purposes. They are likely to be accurate enough to be a...

A common feature of numerous studies on early warning systems (EWS) of currency crisis is the use of an index of exchange market pressure, defined as a weighted average of the rate of depreciation, the monthly percentage changes in international reserves, and sometimes the inclusion of the...
