This paper develops a limiting theory for Wald tests of weak exogeneity in error correction models (ECMs). It is well known that Wald statistics on cointegrated systems may involve nonstandard distribution and nuisance parameters, if $I(1)$ variables are not negligible in the statistics. To...

This paper shows that the Mexican experience from 1945 to 2002 is, like the German hyperinflation period, a unique monetary ``natural experiment,'' where fundamental relationships, like money demand, PPP and the monetary model of exchange rate determination can be analyzed with unparalleled...

This paper analyzes nonlinear cointegrating regressions as have been recently analyzed in a paper by Park and Phillips in Econometrica. I analyze the consequences of removing Park and Phillips' exogeneity assumption, which for the special case of a linear model would imply the asymptotic...

We study participation and relative earnings in the formal, informal, and self-employed sectors in Bolivia. We estimate quantile earnings equations corrected for self-selectivity to address potential biases in the estimates of relative earnings gaps due to the endogeneity of sector...

This paper seeks to shed light on how manufacturing job flows and productivity in Argentina were affected during the 1990s by economic reforms in general and particularly by: a) financial shocks, b) labor reforms that change non-wage labor costs, c) trade reforms that alter tariff dispersion, d)...
