Motu working papers are research materials circulated by their authors for the purpose of information and discussion. They are reviewed, but not formally refereed. Any opinions expressed in papers are those of the author and do not represent a Motu position.
Inequality and Health: Is Housing Crowding the Link?
In this study we extend the literature (e.g. Deaton, 2002a; Kennedy and Kawachi, 1996; Wilkinson, 1996) by proposing a new mechanism through which income inequality can influence health. We argue that increased income inequality induces household crowding, which in turn leads to increased...

Geographic Concentration and Firm Productivity
Firms operating in dense labour markets are more productive, although understanding the mechanisms behind this relationship is both challenging and contentious. This paper uses a newly assembled dataset on location and labour productivity of most New Zealand firms to examine the role of...

Land-Use Intensity Module: Land Use in Rural New Zealand Version 1
This document outlines the development of the dynamic functions and simple algorithms that make up the Land Use in Rural New Zealand (LURNZ) land-use intensity module. The module includes stocking rate functions for dairy, sheep, and beef livestock; fertiliser intensity functions for dairy...

Greenhouse Gas Emissions Charges and Credits on Agricultural Land: What Can a Model Tell Us?
Using the simulation model Land Use in Rural New Zealand version 1 - climate (LURNZv1-climate), we simulate the effects of an agricultural land-use emissions charge and a reward for native forest and scrub regeneration. Our results are preliminary and at this stage should be considered...

The Ups and Downs of New Zealand House Prices
This paper identifies the expansion and contraction phases of New Zealand's national and regional house prices, by employing techniques typically used to study cycles in real activity, the so-called Classical cycle dating method. We then enquire into the nature of the cycles, addressing...

How Important is Selection? Experimental Vs Non-experimental Measures of the Income Gains from Migration
Measuring the gain in income from migration is complicated by nonrandom selection of migrants from the general population, making it hard to obtain an appropriate comparison group of non-migrants. This paper uses a migrant lottery to overcome this problem, providing an experimental measure...

Housing Supply and Price Adjustment
We analyse two inter-related features of regional housing markets: determinants of new housing supply, and the impact of supply responsiveness on price dynamics. We demonstrate that a suitably specified q-theory model (including residential land values as well as construction costs)...
