Contemporary Microeconomic Foundations for the Structure and Management of the Public Sector (WP 12/01)
WP 12/01. Authors: Lewis Evans, Graeme Guthrie and Neil Quigley. This paper examines the findings of research into international developments in the economic theory of the firm, and its implications for public sector organisation, in the quarter of a century since New Zealand adopted significant public sector reforms.
Health and Retirement of Older New Zealanders (WP 12/02)
Authors: Emma Gorman, Grant M Scobie and Andy Towers. Increasing life expectancies and uncertainty about future retirement incomes are likely to lead to various changes in behaviour. As expectations are revised, one potentially important adjustment mechanism is in labour force participation rates. There is already evidence these are rising for those beyond the age of eligibility for New Zealand Superannuation.
The Elasticity of Taxable Income in New Zealand (WP 12/03)
Authors: Iris Claus, John Creedy and Josh Teng. The paper provides estimates of the extent to which reported taxable incomes change as a result of people responding to changes in the marginal income tax rates that they face.
Average Marginal Income Tax Rates for New Zealand, 1907-2009 (WP 12/04)
Authors: Fiona McAlister, Debasis Bandyopadhyay, Robert Barro, Jeremy Couchman, Norman Gemmell and Gordon Liao. Estimates of marginal tax rates (MTRs) faced by individual economic agents, and for various aggregates of taxpayers, are important for economists testing behavioural responses to changes in those tax rates. This paper reports estimates of a number of personal marginal income tax rate measures for New Zealand since 1907.
Economy-Wide Impacts of Industry Policy (WP 12/05)
Author: Anita King. The economy-wide effects of an economic development or industry policy are often ignored when developing or evaluating such a policy. However, these effects may be important for national welfare and can be estimated using CGE modelling. This paper explains the basics of CGE modelling in general and for the two models used in this paper. It then applies CGE modelling to four industry policy scenarios for the New Zealand economy to illustrate how it can be used and the range of results (including counter-intuitive results) that such models can provide.
