This study uses cross-county variation in support for 46 ballot measures to identify political subcultures in South Dakota and to study them. A hierarchical clustering method applied to county-level election returns allows the identification of subcultures at various levels of granularity. We...

We note that calibration parameters in a multi-country Armington trade model play a role similar to that of econometric residuals: they allow the model to fit the data exactly. We use this premise to evaluate the "fit" of a standard multi-country computable general-equilibrium model. We find...

We present an empirical implementation of a general-equilibrium model of international trade with heterogeneous manufacturing firms. The theory underlying our model is consistent with Melitz (2003). A nonlinear structural estimation procedure identifies a set of core parameters and unobserved...

Total U.S. trade with NAFTA partners has increased 78 percent in real terms since 1993U.S.-Mexico trade alone is up 141 percentcompared to a 43 percent increase in U.S. trade with the rest of the world. In this article we compare the nature of U.S. trade growth with Canada and Mexico to growth...

"Dawkins, Srinivasan, and Whalley ("Calibration,""Handbook of Econometrics, "2001) propose that estimation is calibration. We illustrate their point by examining a leading econometric application in the study of international and interregional trade by Anderson and van Wincoop ("Gravity with...

We present an empirical implementation of a general-equilibrium model of international trade with heterogeneous manufacturing firms. The theory underlying our model is consistent with Melitz (2003). A nonlinear structural estimation procedure identifies a set of core parameters and unobserved...

Borders affect the composition, not only the level, of interregional trade. In disaggregated U.S. Commodity Flow data, border effects vary substantially across commodities. Substantial border-induced compositional change suggests the possibility that standard estimates suffer from aggregation...

We present an empirical implementation of a general-equilibrium model of international trade with heterogeneous manufacturing firms. The theory underlying our model is consistent with Melitz (2003) and Bernard et al. (2004). A nonlinear structural estimation procedure identifies a set of core...

Many contemporary theoretic studies of trade over geography reduce to an ex- amination of constant-elasticity reactions to changes in iceberg trade costs. These impacts are readily analyzed in simple constant-returns models based on the Arm- ington (1969) assumption of regionally differentiated...
