This paper studies how migration from a poor to a rich country affects key economic beliefs, preference parameters, and transnational household decision-making efficiency. The setting is the migration of Tongans to New Zealand through a migration lottery program. In a 10-year follow-up survey of...

This study examines the long-term impacts of international migration by comparing immigrants who had successful ballot entries in a migration lottery program, and first moved almost a decade ago, with people who had unsuccessful entries into those same ballots. The long-term gain in income is...

We examine the long-term impacts of international migration by comparing immigrants who had successful ballot entries in a migration lottery program, and first moved almost a decade ago, with people who had unsuccessful entries into those same ballots. The long-term gain in income is found to be...

Emigration to New Zealand and consequent remittance inflows are dominant features of many Pacific Island countries. Evaluating the effect of these people and money flows on incomes and poverty in the Pacific is potentially complicated by the non-random selection of emigrants. This paper uses the...
