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.

2. Labor Market Search in Emerging Economies

Abstract:
This paper shows that labor markets of emerging economies are characterized by large fluctuations in wages while employment fluctuations are subdued. We find that a real business cycle model of a small open economy that embeds a Mortensen-Pissarides type of search-matching frictions can account for these aforementioned regularities. Moreover, the joint interaction of countercyclical interest rates and search-matching frictions can go a long way in accounting for higher consumption variability relative to output and countercyclical current account observed in emerging markets. Extending this baseline model to incorporate procyclical variations in the technical efficiency at which matches are generated, the model can match the unemployment variability observed in the data.

Abstract:
The data reveal that emerging markets do not differ from developed countries with regards to the variance of permanent TFP shocks relative to transitory. They do differ, however, in the degree of uncertainty agents face when formulating expectations. Based on these observations, we build an equilibrium business cycle model in which the agents cannot perfectly distinguish between the permanent and transitory components of TFP shocks. When formulating expectations, they assign some probability to TFP shocks being permanent even when they are purely transitory. This is sufficient for the model to produce "permanent-like" effects in response to transitory shocks. The imperfect information model calibrated to Mexico predicts a higher variability of consumption relative to output and a strongly negative correlation between the trade balance and output, without the predominance of trend shocks. The same model assuming perfect information and calibrated to Canada accounts for developed country business cycle regularities. The estimated relative variance of trend shocks in these two models is similar.

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.
