This paper, based on the introductory remarks made at the two-day conference on "The State of the Economy, the State of the World," is an idiosyncratic stocktaking of the trajectory of economics from Adam Smith to contemporary times, with special attention to the rise of development economics....

This paper analyzes the impacts of selected trade facilitation measures on international trade flows. A gravity model is used to estimate four equations: a pooled cross-section model; a fixed-effects model; a random effects model; and a Poisson maximum likelihood estimator. The contribution of...

This paper examines systematically the growth effects of trade integration in Sub-Saharan Africa. It complements and improves upon the empirical literature in two aspects: first, it jointly estimates the impact of different dimensions of trade integration, namely, trade volumes, export/trade...

This paper provides up-to-date characterization of the association between trade and GDP comovement -- also called the trade comovement slope -- for 150 countries from 1962 to 2011. The paper shows that trade is significantly linked to more GDP correlation, either directly through bilateral...

Since the Global Financial Crisis, world trade growth has been subdued and lagging slightly behind growth of gross domestic product. Trade is growing more slowly not only because growth of global gross domestic product is lower, but also because trade itself has become less responsive to gross...

In the 1990s the mainstream consensus was that trade causes growth. Subsequent research shed doubt on the consensus view, as evidence suggested that the identification of the effect of trade on growth was problematic in the existing literature. This paper contributes to this debate by focusing...

Traditional weighted-average measures of trade distortions are widely used in analyzing global and regional reforms, despite well-known deficiencies. This paper develops and applies optimal aggregators for the real-world case of multiple countries and commodities with much more detailed...

While the real sector and governments (along with a few micro economists) have long recognized the core economic role that the insurance function plays, the mainstream economics profession has largely treated it as invisible background. This literature review of the relevant research, most of...

Forced displacement -- defined as the displacement of refugees and internally displaced persons due to violence -- has reached an unprecedented scale and global attention during the past few years, particularly in the aftermath of the Syrian refugee crisis in 2011 and the European Union's...

Governments must decide how to allocate limited resources for infrastructure development, particularly since financing gaps have been projected for the coming decades. Social cost-benefit analysis provides sound project appraisal and, when systematically applied, a basis for prioritization. In...
