Gravity models of international trade have been frequently applied to estimate the impact of common (official or spoken) language on bilateral trade. This study provides a meta-analysis based on 701 language effects collected from 81 academic articles. On average, a common (official or spoken)...

We investigate the prevalence and determinants of ethnic favoritism, i.e., preferential public policies targeted at the political leader's ethnic group. We construct a panel dataset of 2,022 ethnographic regions from 139 countries with annual observations from 1992 to 2012, and use nighttime...

While the direct impact of geographic endowments on prosperity is present in all countries, in former colonies, geography has also affected colonization policies and, therefore, institutional outcomes. Using non-colonized countries as a control group, I re-examine the theories put forward by La...

This study analyzes the determinants of stress in public-private partnerships (PPPs) in infrastructure investment. While project failures seldom occur, there are many stresses that hinder success. One of these is broad political risk: the prerogative of government executives to make sweeping...

This study evaluates infrastructure investment and finance in Asia from a global perspective. It provides an overview on infrastructure needs and the various sources of private finance, globally and within Asia, and creates a "bigger picture" for the demand and supply of capital for...

This paper surveys recent research on decentralization and natural disasters. The first part discusses results from theoretical models that have been used to study the issues that arise when natural disasters occur in a country with more than one level of government. The next section discusses...

This paper deals with the implications of natural resources for the conduct of economic policies and the role and design of institutions in resource‐rich countries. The paper briefly reviews the experience of a few resource‐rich countries, highlighting the successes of those that have done...

We explore the relationships between subjective well-being and income, as seen across individuals within a given country, between countries in a given year, and as a country grows through time. We show that richer individuals in a given country are more satisfied with their lives than are poorer...

We study the impact of global climate change on the prevalence of tropical diseases using a heterogeneous agent dynamic general equilibrium model. In our framework, households can take actions (e.g., purchasing bednets or other goods) that provide partial protection from disease. However, these...

We present a novel approach for measuring democracy based on Support Vector Machines, a mathematical algorithm for pattern recognition. The Support Vector Machines Democracy Index (SVMDI) is continuously on the 0-1-interval and enables a very detailed measurement of democracy for 188 countries...
