This paper argues that the conventional approach of data averaging is problematic for exploring the growth–inequality nexus. It introduces the polynomial inverse lag (PIL) framework so that the impacts of inequality on investment, education, and ultimately on growth can be measured at...

This paper analyses the decentralization of decisionmaking in aid-giving in a theoretical rent-seeking framework. In this analysis the root donor establishes a necessary criterion for potential recipients: good governance. The potential recipients compete in hierarchal contests for funds. The...

This paper surveys the various composite well-being indices that have been inter-country assessments over the last 40 or so years, including the well known Human Development Index (HDI). A number of issues are considered, including the choice of components, component weights, scale equivalence,...

This study documents four key facts about informal economic activities: (1) the size of the informal sector varies greatly across nations; (2) this size is strongly correlated with economic development, the tax burden, and the rule of law; (3) the informal sector emphasizes small-scale,...

This paper presents a simple model to show how distributional concerns can engender social conflict. We have a two period model, where the cost of conflict is endogenous in the sense that parties involved have full control over how much conflict they can create. We find that anticipated future...

Recent years have witnessed important structural changes around the world as a result of the globalization process, the creation of new economic blocks and the liberalization of financial sector in many countries. Responding to these changes many sectors of the industrialized countries have gone...

This paper provides empirical evidence on the relationship between exports, and in particular export diversity, and regional growth in a developing country context. Using export data for 19 sectors from 354 subnational (magisterial) districts of South Africa, we construct various measures of...

This paper surveys 50 years of empirical research on the macroeconomic impact of aid, looking mainly at studies examining the link between aid and growth. It argues that studies dating until the late 1990s produced either contradictory or inconclusive results. Aid either worked, or it didn’t,...

The literature on aid has come a long way in recent years, and as a result we now know much more about aid effectiveness than possibly ever before. But significant gaps in knowledge remain. One such gap is the effectiveness of aid in the so-called ‘fragile states’, countries with critically...
