The "distance effect" measuring the elasticity of trade flows to distance has been rising since the early 1970s in a host of studies based on the gravity model, leading observers to call it the "distance puzzle". This paper reviews the evidence and explanations. Using an extensive data set of...

This paper complements the cross-country approach by examining the correlates of growth acceleration in per capita gross domestic product around "significant" public expenditure episodes by reorganizing the data around turning points, or events. The authors define a growth event as an increase...

The estimated coefficient of distance on the volume of trade is generally found to increase rather than decrease through time using the traditional gravity model of trade. This distance puzzle proved robust to several ad hoc versions of the model using data for 1962-96 for a large sample of 130...
