Distance and location are important determinants of many choices that economists study. While these variables can sometimes be obtained from secondary data, economists often rely on information that is self-reported by respondents in surveys. These self-reports are used especially for the...

Measuring the gain in income from migration is complicated by non-random selection of migrants from the general population, making it difficult to obtain an appropriate comparison group of non-migrants. This paper uses a migrant lottery to overcome this problem, providing an experimental measure...

Remittances are a major source of external finance for many developing countries but the cost of sending remittances remains high for many migration corridors. International efforts to lower costs by facilitating the entry of new financial products and new cost comparison information sources...

Lack of mobility of labor is likely the biggest distortion in global factor markets, resulting in large differences in the productivity and income a given worker can have in different places. As a result of this fact, facilitating emigration has the potential to be one of the most effective...

Lowering the cost of sending remittances has become a major goal of policy efforts in migration, and an area the World Bank has worked on across the globe. Two main channels for lowering these costs are regulatory reforms to promote competition and the introduction of new products; and efforts...

This paper uses data from eight different consumption questionnaires randomly assigned to 4,000 households in Tanzania to obtain evidence on the nature of measurement errors in estimates of household consumption. While there are no validation data, the design of one questionnaire and the...

There is widespread interest in the number of hungry people in the world and trends in hunger. Current global counts rely on combining each country's total food balance with information on distribution patterns from household consumption expenditure surveys. Recent research has advocated for...

Using Global Positioning Systems in Household Surveys for Better Economics and Better Policy John Gibson David McKenzie Distance and location are the important determinants of many choices that economists study. This article reviews four ways that GPS can lead to better economics and better...

How much do migrants stand to gain in income from moving across borders? Answering this question is complicated by non-random selection of migrants from the general population, which makes it hard to obtain an appropriate comparison group of non-migrants. New Zealand allows a quota of Tongans to...

Households and communities in the Pacific islands are increasingly likely to have some of their most productive members regularly absent due to growing opportunities for seasonal work abroad. If these absences are costly for the family left behind, the net development benefits of seasonal...
