Output volatility and openness to trade: a reassessment

This paper presents new empirical evidencesuggesting that the net effect of trade openness on output volatility is stabilizing. The methodology employed seeks to correct for the likely endogeneity of trade in this setting using gravity estimates as instrumental variables. The results confirm that exposure to trade raises output volatility through the terms-of-trade channel, as previously documented in the literature, but also shows that this is counteracted by a quantitatively larger stabilizing effect. Additional evidence is presented showing that the latter effect comes (at least in part) through the financial channel. Splitting the sample into countries that are more exposed to capital flows and countries that are less exposed, the paper shows that the stabilizing effect of commercial trade predominates in the first sub-sample.(This abstract was borrowed from another version of this item.)
