This paper argues that localized price spikes should be a regular feature of competitive commodity markets. It develops a rational expectations model of physical arbitrage in which trade takes time, and shows that inventory management plays a crucial role in the way regional prices are...

This article solves a high-frequency model of price arbitrage incorporating storage and trade when the amount of trade is limited by transport capacity constraints. In equilibrium there is considerable variation in transport prices because transport prices rise when the demand to ship goods...

This paper uses disaggregated price data to analyse the extent and the speed of retail price convergence between New Zealand and Australia since 1984. The paper addresses several issues concerning the integration of markets in the two countries. It compares the behaviour of the prices of a set...

Recent research shows that trade of goods and financial products is much greater within countries than it is between countries, even allowing for factors such as transports costs. This lack of economic integration is likely to be costly for small nations, as internal trade is much less diverse...

This paper examines how increasing longevity affects the housing choices of working age and retired people using a heterogeneous agent overlapping generations model that incorporates owner-occupier and rental sectors, credit constraints, detailed tax regulations, and a housing supply sector....

Land taxes are known to be amongst the most efficient forms of taxation since land is an immobile factor; property (capital value) taxes are less efficient owing to the tax on improvements. However there is little international (or New Zealand) evidence regarding the distributional impacts of...

This paper develops a simple model that captures the essential features of the supply and demand for housing, and which is used to evaluate the impact of a range of policy interventions. The model incorporates functions describing the demand to rent or purchase housing, a function describing the...

This paper develops a model of the housing market incorporating a construction sector, a rental sector, and a housing demand sector to examine the long term consequences for the housing market of different types of capital gains taxes. The sector is based on an overlapping generations model of...
