Qualification and occupation-based measures of skilled labour are constructed to explain the skill premium – the wage of skilled labour relative to unskilled labour in New Zealand. The data exhibit a more rapid growth in the supply of skilled labour than the skill premium, and a very large...

We estimate the effect of four types of education qualifications, as a proxy for human capital and skill levels, on GDP per capita, and compute the average percentage returns. We also test the effect of the product of each proxy of human capital with R&D on GDP per capita. We find that only...

Modern economic theories explain differences in productivity and economic growth across countries by differences in political and economic institutions, and differences in culture, geographical location, policies, and laws. The success of any of these theories in explaining the gap in...

Qualification and occupation-based measures of skilled labour are constructed to explain the skill premium – the wage of skilled labour relative to unskilled labour in New Zealand. The data exhibit a more rapid growth in the supply of skilled labour than the skill premium, and a very large...

A persistent increase in the unemployment rate ignites speculations about whether the changes to unemployment are structural or cyclical. The New Zealand economy has been through major restructuring since the mid-1980s. The labour market’s institutional changes were the last in the sequence of...

We use the work-leisure choice model to estimate equilibrium labour supply (hours-worked) in New Zealand over the period 2000 – 2008. We then stochastically solve the model over a future period from 2010 to 2050, and evaluate the New Zealand’s new tax policy. We compare the welfare and...

We use the work-leisure choice model to compute equilibrium weekly hours worked for a number of Arab countries, where actual statistics are unavailable. We show that the labor supply curve is elastic in all Arab countries, and provide a new measure of labor productivity. This finding confirms...

We confront microeconomic theory with macroeconomic data. Unemployment results from two main micro-level decisions of workers and firms. Most of the efficiency wage and bargaining theories predict that over the business cycle, unemployment falls below its natural rate when the worker’s real...

Unanticipated shocks could lead to instability, which is reflected in statistically significant changes in distributions of random variables. Changes in the conditional moments of stationary variables are predictable. We provide a framework based on a statistic for the Sample Generalized...

I extend the Glick and Rogoff (1995) aggregate time-series, empirical, intertemporal model of country-investment (and the current account) to a sectoral-level, and estimate it for New Zealand. I fit the model to panel data of eleven industries from 1988-2009. The sectoral-level investment growth...
