Several alternative measures of "effective" exchange rates are discussed in the context of their theoretical underpinnings and actual construction. Focusing on contemporary indices and recently developed econometric methods, the empirical characteristics of these differing series are examined,...

This paper addresses the puzzle of regime-dependent volatility in foreign exchange. We extend the literature in two ways. First, our microstructural model provides a qualitatively new explanation for the puzzle. Second, we test implications of our model using Europe's recent shift to rigidly...

We build a quantitative model of trade with multistage manufacturing value chains, which features iceberg trade costs and technology differences across both goods and production stages. We estimate technology and trade costs via the simulated method of moments, matching bilateral shipments of...

We propose a local measure of the relationship between parameter estimates and the moments of the data they depend on. Our measure can be computed at negligible cost even for complex structural models. We argue that reporting this measure can increase the transparency of structural estimates,...

We propose a simple saving-based measure of the cyclical component in GDP. The measure is motivated by the prediction that the represenative consumer changes savings in response to temporary deviations of income from its stochastic trend, while satisfying a present-value budget constraint. To...

In a model where a variable Y[sub t] is proportional to the present value, with constant discount rate, of expected future values of a variable y[sub t] the "spread" S[sub t]= Y[sub t] - [theta sub t] will be stationary for some [theta] whether or not y[sub t]must be differenced to induce...

A classic argument for a fixed exchange rate is its promotion of trade. Empirical support for this, however, is mixed. While one branch of research consistently shows a small negative effect of exchange rate volatility on trade, another, more recent, branch presents evidence of a large positive...
