A powerful method for computing Nash equilibria in constrained, multi-player games is created when the relaxation algorithm and the Nikaido-Isoda function are used within a MATLAB application. This paper describes that application, which is able to solve static and open-loop dynamic games...

We provide an introduction to a model of social inequality dynamics. Because capital is distributed less equally than labour, we propose that that one of the main forces driving income inequality is the ratio of factor shares. In this paper we give an easy proof to show that this ratio is driven...

This paper examines whether changes in New Zealand income inequality can be attributed to the shares of national income taken by capital and labour. Data on income inequality aggregates both capital income (rents, interest, profits) and labour income (wages and salaries). It is possible that...

In the Self Sufficiency Program (SSP) welfare demonstration, members of a randomly assigned treatment group could receive a subsidy for full time work. The subsidy was available for three years, but only to people who began working full time within 12 months of random assignment. A simple...

In the Self Sufficiency Project (SSP) welfare demonstration, members of a randomly assigned treatment group could receive a subsidy for full-time work. The subsidy was available for 3 years, but only to people who began working full time within 12 months of random assignment. A simple optimizing...

In the Self Sufficiency Project Applicant Experiment, new welfare entrants were informed that if they remained on public assistance for a year they would become eligible to receive a generous earnings subsidy offer. Those who satisfied the waiting period, and then left welfare and began working...

This paper analyses changes in the distribution of equivalised gross household income and income inequality in New Zealand between 1983 and 1998. We analyse the distributional effects of changes in household structure, National Superannuation (old age pension), household socio- demographic...

In this paper we document patterns of annual employment across jobs, workers and firms, and examine the relationship between these patterns and job-level earnings rates using data from Statistics New Zealand’s Linked Employer-Employee Database (LEED). First, we characterise workers’ annual...

We consider the implications of a specific alternative to the classical measurement error model, in which the data are optimal predictions based on some information set. One motivation for this model is that if respondents are aware of their ignorance they may interpret the question what is the...
