The paper revisits the issue of poverty-specific purchasing power parities (PPPs), using the most recent (2011) International Comparison Program (ICP) results. The World Bank's global poverty count uses a common international poverty line -- currently $1.90 at 2011 international prices-based on...

Learning from experience to improve future infrastructure public-private partnerships is a focal issue for policy makers, financiers, implementers, and private sector stakeholders. An extensive body of case studies and "lessons learned" aims to improve the likelihood of success and attempts to...

This paper investigates cross-sectoral productivity differentials in South African industry and their distributional consequences. The analysis shows that typically, traded sectors have experienced low productivity growth over the past decade, while skill intensive service sectors have had...

This paper assesses the equilibrium value of the Argentine peso exchange rate based on the country's economic fundamentals and compares it with the official exchange rate value. The paper estimates a behavioral equilibrium exchange rate model that allows for movements in the equilibrium real...

This paper makes analytical, methodological and empirical contributions to the literature on purchasing power parity. Purchasing power parities are required in a host of cross-country welfare comparisons, such as poverty rates and gross domestic product. The subject has recently generated much...

This paper analyzes how the exchange rate elasticity of exports has changed over time and across countries and sectors, and how the formation of global value chains has affected this relationship. The analysis uses a panel framework covering 46 countries over the period 1996-2012, and first...

A widely shared view holds that there is no policy-exploitable causal connection from saving to growth because domestic saving is fully endogenous, optimally determined, or substitutable by foreign saving. Yet, abandoning these assumptions, which are questionable in the real world of frictions,...

This paper considers the determinants of exports of modern services and traditional services. It considers the growth of export volumes as well as export surges, that is, the periods of rapid sustained export growth. It asks whether the determinants of export growth rates and export surges...

Aid donors and recipients have long been concerned that aid inflows may lead to an appreciation of the real exchange rate and an associated loss of competitiveness. This paper provides new evidence of the dynamic effects of aid on the real exchange rate, using an identification strategy that...

This paper models empirically the short and long-term behavior of the real exchange rate misalignment -- a key variable in academic and policy circles. The equilibrium real exchange rate is derived from a theoretical model with intertemporal external equilibrium and internal equilibrium (in...
