As in other OECD countries, women in New Zealand earn substantially less than men with similar observable characteristics. In this paper, we use a decade of annual wage and productivity data from New Zealand's Linked Employer-Employee Database to examine different explanations for this gender...

Minority groups in many countries, particularly indigenous populations, live in very segregated environments. Many social scientists believe that social networks create poverty traps in these types of segregated environments, with a lack of positive role models reinforcing a lack of good job...

Research consistently finds more workplace injuries occur on Mondays than on other weekdays. One hypothesis is that workers fraudulently claim that off-the-job weekend sprains and strains occurred at work on the Monday in order to receive workers' compensation. We test this using data from New...

Between 1984 and 2003, New Zealand undertook comprehensive market-oriented economic reforms. In this paper, we use Census data to examine how the internal mobility of Māori compares to that of Europeans in New Zealand in the period after these reforms. It is often suggested that Māori are less...

This paper exploits the reduction in the legal drinking age in New Zealand from 20 to 18 to study the dynamics of youth risk taking. Using administrative data on the universe of road accidents over a fifteen year period spanning the law change, we undertake three complimentary analyses to...

Obesity rates have risen dramatically in the US since the 1980s, but well-identified studies have struggled to explain the magnitude of the observed changes. In this paper, we estimate the causal impact of economic insecurity on obesity rates. Specifically, we construct a synthetic panel of...

We show that the exposure to war-related violence increases the quantity of children temporarily, with permanent negative consequences for the quality of the current and previous cohort of children. Our empirical evidence is based on Nepal, which experienced a ten year long civil conflict of...

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...

Many immigrants are overqualified in their first job after arrival in the host country. Education-occupation mismatch can affect the economic integration of immigrants and the returns to education and experience. The extent of this problem has been measured in recent years by means of micro...
