Current estimates of global poverty vary substantially across studies. In this paper we undertake a novel sensitivity analysis to highlight the importance of methodological choices in estimating global poverty. We measure global poverty using different data sources, parametric and nonparametric estimation methods, and multiple poverty lines. Our results indicate that estimates of global poverty vary significantly when they are based alternately on data from household surveys versus national accounts but are relatively consistent across different estimation methods. The decline in poverty over the past decade is found to be robust across methodological choices.
This paper presents an alternative method for calculating debt targets using the debt intolerance literature of Reinhart, Rogoff, and Savastano (2003) and Reinhart and Rogoff (2009). The methodology presented improves on the previous papers by using a dynamic panel approach, correcting for endogeneity in the regressors and basing the calculation of debt targets on credit ratings, a more objective criteria. In addition the study uses a new data base on general government debt covering 120 countries over 21 years. The paper suggests a ranking of Central America, Panama, and Dominican Republic (CAPDR) countries in terms of debt intolerance - an index which could be used to further investigate the main components of debt intolerance.
This paper investigates Central America's external linkages over the last fifteen years of increased integration in light of the 2008-09 global recession. Using structural VAR models, it is found that a one percent shock to U.S. growth shifts economic activity in Central America by 0.7 to 1 percent, on average. Spillovers from global shocks and the rest of the region also affect activity in some countries. Spillovers are mostly transmitted through advanced country financial conditions and fluctuations in external demand for Central American exports. Shocks to advanced economies associated with the 2008-09 financial crisis lowered economic activity in the region by 4 to 5 percent, on average, accounting for a majority of the observed slowdown. The impact was almost twice as large as elasticities estimated on pre-crisis data would have predicted. These results underscore the importance of operating credible policy frameworks that enable a countercyclical policy response to external shocks.
This paper extends my previous work by examining the relationship between monetary policy and exchange market pressure (EMP) in 32 emerging market countries. EMP is a gauge of the severity of crises, and part of this paper specifically analyzes crisis periods. Two variables gauge the stance of monetary policy: the growth of central bank domestic credit and the interest differential (domestic versus U.S. dollar). Evidence suggests that monetary policy plays an important role in currency crises. And, in most countries the shocks to monetary policy affect EMP in the direction predicted by traditional approaches: tighter money reduces EMP.
