Over 200 million people live outside their country of birth and experience large gains in material well-being by moving to where wages are higher. But the effect of this migration on health is less clear and existing evidence is ambiguous because of the potential for self-selection bias. In this...

Brain drain has long been a common concern for migrant-sending countries, particularly for small countries where high-skilled emigration rates are highest. However, while economic theory suggests a number of possible benefits, in addition to costs, from skilled emigration, the evidence base on...

The impacts of international migration on development in the sending countries, and especially the effects on remaining household members, are increasingly studied. However, comparisons of households in developing countries with and without migrants are complicated by a double-selectivity...

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...

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

This paper estimates the non-increasing inflation rate of unemployment or NAIRU for New Zealand. A NAIRU that varies over time has important implications in considering inflationary pressures. This paper estimates the time-varying NAIRU using a Kalman filter on a reduced form approach and...

This paper investigates and compares the dynamic properties of the New Zealand Treasury model (NZTM) and the current version of the Reserve Bank’s Forecasting and Policy System model (FPS). The main use of both two models is to produce macroeconomic forecasts. The NZTM model produces forecasts...

There is an on-going debate about the level of savings in New Zealand. A fundamental question pervades the debate: namely, are we saving enough? This question arises at two levels: for the economy as a whole and for individual households. At the macroeconomic level, the concern is whether our...

Policy interventions that affect or are mediated through the family typically assume a behavioural response. Policy analyses proceeding from different disciplinary bases may come to quite different conclusions about the effects of policies on families, depending how individuals within families...

Bargaining models of household wealth accumulation point to a potential conflict of interest between husbands and wives. Since wives are typically younger than their husbands and have longer life expectancy, they have to finance a longer expected retirement period. Thus, it is argued that when...
