A Forward-Looking Measure of the Stock of Human Capital in New Zealand

Human capital is increasingly believed to play an important role in the growth process; however, adequately measuring its stock remains controversial. Because the estimated impact that human capital has on economic growth is sensitive to the measures or proxies of human capital, accurate and consistent measures are needed. While many measures of human capital have been developed, most rely on some proxy of educational experience and are thus plagued with limitations. In this study, we modify the lifetime labour income approach outlined by Jorgenson and Fraumeni (The Measurement of Savings, Investment and Wealth, Chicago, IL, University of Chicago Press, 1989, pp. 227–282; Output Measurement in the Services Sector, Chicago, IL, University of Chicago Press, 1992, pp. 303–338) to estimate the monetary value of the human capital stock for New Zealand. Based on data from the New Zealand Census of Population, we find that the countrys working human capital grew by half between 1981 and 2001, mostly due to the rise in employment level. This stock of human capital was also well over double that of physical capital in all the census years studied.

What Explains the Wealth Gap between Immigrants and the New Zealand Born

Immigrants are typically found to have less wealth and hold it in different forms than the native born. These differences may affect both the economic assimilation of immigrants and overall portfolio allocation when immigrants are a large share of the population, as in New Zealand. In this paper, data from the 2001 Household Savings Survey are used to examine wealth differences between immigrants and the New Zealand-born. Differences in the allocation of portfolios between housing and other forms of wealth are described. Unconditional and conditional wealth quantiles are examined using parametric models. Semiparametric methods are used to decompose differences in net worth at different parts of the wealth distribution into the part due to differences in characteristics and the part due to differences in the returns to characteristics.

The Relationship between Individual Labour Market Outcomes, Household Income and Expenditure, and Inequality and Poverty in New Zealand from 1983 to 2003

This paper investigates the relationship between individual labour market outcomes, household income and expenditure, and inequality and poverty in New Zealand using detailed data from the 1983/84 – 2003/04 Household Economic Survey (HES). We begin by discussing and summarising measures of income and expenditure calculated from the HES. We next examine the relationship between individual labour market outcomes, and household income and expenditure for households with different characteristics. In particular, we focus on how this relationship varies over the life cycle and over time. This analysis is then extended to examine inequality in labour market outcomes, household income and household expenditure. In the last section, we examine the determinants of the levels and changes in poverty in New Zealand using both expenditure and income data. We also apply a newly developed methodology for combining income and expenditure data to produce poverty indicators.

Household Bargaining Over Wealth And The Adequacy Of Women'S Retirement Incomes In New Zealand

Abstract Bargaining models of household wealth accumulation point to a potential conflict of interest between husbands and wives. Wives are typically younger than their husbands and have longer life expectancy, so they must expect to finance a longer retirement period. Therefore, when they have greater relative bargaining power, households will accumulate more wealth. There is some weak evidence for this in the United States, but this article finds the opposite pattern in New Zealand, where womens greater bargaining power results in a lower net worth in the pre-retirement cohort of couples. In New Zealand, where public pensions are more generous than in the US and are not affected by holdings of private wealth or income, it may not be rational for women with greater relative bargaining power than their spouses to favor wealth accumulation. These results indicate the importance of the policy context when considering household bargaining models.

The Impact of R&D Subsidy on Innovation: A Study of New Zealand Firms

This paper examines the impact of government assistance through R&D grants on innovation output for firms in New Zealand. Using a large database that links administrative and tax data with survey data, we are able to control for large number of firm characteristics and thus minimise selection bias. We find that receipt of an R&D grant significantly increases the probability that a firm in the manufacturing and service sectors applies for a patent during 2005–2009, but no positive impact is found on the probability of applying for a trademark. Using only firms that participated in the Business Operation Survey, we find that receiving a grant almost doubles the probability that a firm introduces new goods and services to the world while its effects on process innovation and any product innovation are relatively much weaker. Moreover, there is little evidence that grant receipt has differential effects between small to medium (

Is there an educational penalty for being suspended from school

Suspension from school is a commonly used, yet controversial, school disciplinary measure. This paper uses unique survey data to estimate the impact of suspension on the educational outcomes of those suspended. It finds that while suspension is strongly associated with educational outcomes, the relationship is unlikely to be causal, but rather likely stems from differences in the characteristics of those suspended compared to those not suspended. Moreover, there is no evidence that suspension is associated with larger educational penalties for young people from disadvantaged family backgrounds compared to those from more advantaged family backgrounds. These results hold regardless of whether self-reported suspension or mother-reported suspension is considered. The absence of a clear negative causal impact of suspension on educational outcomes suggests that suspension may continue to play a role in school discipline without harming the educational prospects of those sanctioned.

Decomposing Differences in Labour Force Status between Indigenous and Non-Indigenous Australians

Despite several policy efforts to promote economic participation by Indigenous Australians, they continue to have low participation rates compared to non-Indigenous Australians. This study decomposes the gap in labour market attachment between Indigenous and non- Indigenous Australians in non-remote areas, combining two separate data sources in a novel way to obtain access to richer information than was previously possible. It shows that among women at least two thirds of the gap can be attributed to differences in the observed characteristics between the two populations. For men, the differences in observed characteristics of the two populations can account for 36 to 47 percent of the gap. A detailed decomposition shows that lower education, worse health, and larger families (particularly for women) explain the lower labour market attachment of Indigenous Australians to a substantial extent. Compared with previous studies, this study is able to explain a larger proportion of the gap in employment between Indigenous and non-Indigenous people due to being able to include a larger set of explanatory variables.

Why firm size matters: investigating the drivers of innovation and economic performance in New Zealand using the Business Operations Survey

ABSTRACT The performance of the New Zealand (NZ) economy is something of an enigma. Although ranked one (of 144 countries) for four important ‘growth fundamentals’ NZ is ‘middle of the pack’ when it comes to economic growth, productivity and process innovation. Using four iterations (2005, 2007, 2009 and 2011) of the Business Operations Survey, this research seeks to shed some new light on this conundrum by using a multivariate probit regression (mvprobit) approach applied to pooled samples in excess of 22,000 unit record observations of NZ firms. The results suggest that factors including firm size, high perceived quality, investment/research and development (R&D) capability, major technology change, application of formal IP protection and new export markets are systematically and positively related to innovation; while many external issues, such as those related to geography, market structure, business environment, have little influence. At the firm level, innovations in NZ are highly dependent on the firms’ internal ability to develop new technologies and market demand. The (very small) size of firms does matter in NZ, which lacks a major ‘home market’ or a major trade block on its doorstep, such that ultimately, government may need to be involved to maintain a viable scale for domestic R&D.

High-School: The Relationship between Early Marijuana Use and Educational Outcomes

We use unique survey data linked to nearly a decade of administrative welfare data to examine the relationship between early marijuana use (at age 14 or younger) and young peoples educational outcomes. We find evidence that early marijuana use is related to educational penalties that are compounded by high-intensity use and are larger for young people living in families with a history of welfare receipt. The relationships between marijuana use and both high school completion and achieving a university entrance score appear to stem from selectivity into the use of marijuana. In contrast, early marijuana use is associated with significantly lower university entrance score for those who obtain one and we provide evidence that this effect is unlikely to be driven by selection. Collectively, these findings point to a more nuanced view of the relationship between adolescent marijuana use and educational outcomes than is suggested by the existing literature.

Identifying Important Factors for Closing the Gap in Labour Force Status between Indigenous and non-Indigenous Australians

Despite substantial policy efforts to promote economic participation by Indigenous Australians, they continue to have low participation rates compared with non-Indigenous Australians. This study decomposes the gap in labour market attachment between Indigenous and non-Indigenous Australians in non-remote areas, combining two separate data sources in a novel way to obtain access to richer information than was previously possible. It shows that among women over 90 per cent of the gap can be attributed to differences in the observed characteristics between the two populations. For men, the differences in observed characteristics can account for 44–52 per cent of the gap. A detailed decomposition shows that lower education, worse health, and larger families (particularly for women) explain the lower labour market attachment of Indigenous Australians to a substantial extent. Compared with previous studies, this study is able to explain a larger proportion of the gap in employment between Indigenous and non-Indigenous people and hence provides greater insights into important factors for ‘Closing the gap’ policies.
