Migrants Count: Five Steps Toward Better Migration Data

In this CGD report, the Commission on International Migration Data for Development Research and Policy presents their five recommendations to remedy the lack of good data on migration and its effects on development. The recommendations are politically and technically practical and would allow countries to greatly improve their migration data at low cost, and with existing mechanisms. The first step: ask basic census questions and make the data publicly available.

Rice Price Formation in the Short Run and the Long Run - Working Paper 172

Billions of people depend on rice to survive. During the 2007–08 rice price crisis, the international community increased funding for food aid and governments tried to stabilize their domestic prices—only to further destabilize the world market. In the newest of three CGD working papers on the crisis, non-resident fellow Peter Timmer untangles the factors affecting world grain prices, from simple supply and demand to hoarding, the availability of storage, and the influence of speculation.

Blunt Instruments: On Establishing the Causes of Economic Growth - Working Paper 171

Economists often use instrumental variables to demonstrate a causal relationship between some trait of a country and economic growth. In this new analysis, Samuel Bazzi and Michael Clemens show that a variety of instrumental variables used in top economics journals have severe but hidden limitations. They present three guidelines to improve future empirical studies of growth determinants.
