Abstract:
Theory predicts that a nation's stochastic intertemporal budget constraint is satisfied if net foreign assets (NFA) are integrated of any finite order, or if net exports (NX) and NFA satisfy an error- correction specification with a residual integrated of any finite order. We test these conditions using data for 21 industrial and 29 emerging economies for the 1970-2004 period. The results show that, despite the large global imbalances of recent years, NFA and NX positions are consistent with external solvency. Country-specific unit root tests on NFA-GDP ratios suggest that nearly all of them are integrated of order 1. Pooled Mean Group error-correction estimation yields evidence of a statistically significant, negative response of the NX-GDP ratio to the NFA-GDP ratio that is largely homogeneous across countries.

Abstract:
This paper analyzes the implications of remittance fluctuations for various macroeconomic variables and Sudden Stops. The paper employs a quantitative two-sector model of a small open economy with financial frictions calibrated to Mexican and Turkish economies, two major recipients, whose remittance receipts feature opposite cyclical characteristics. We find that remittances dampen the business cycles in Mexico, whereas they amplify the cycles in Turkey. Their quantitative effects in the long run, approximated by the stochastic steady state are mild. In the short run, however, remittances have quantitatively large impacts on the economy, when the economy is borrowing constrained. This is because agents in the economy cannot adjust their precautionary wealth to sudden tightening in credit, hence, fluctuations in remittances get magnified through an endogenous debt-deflation mechanism. Our findings suggest that procyclical (or countercyclical) remittances can play a significant deepening (or mitigating) role for Sudden Stops.
