Principal-agent models typically rely on the assumption that the agents action has a positive and increasing marginal cost in order to explain the emergence of a moral hazard. This paper develops a model in which an agent can manipulate a projects type, and in particular the projects risk,...

A model of illicit, addictive drug use is proposed when users have foresight. Impacts of drug use penalties, penalties on drug use-related crime, support for drug user rehabilitation as well as the effects of health-related, harm-minimisation policies are analysed. In the short run, government...

In the standard repeat-sales method, the maintained assumption is that the quality does not change between a house?s two sale dates. This assumption has been called into question. In particular quality changes from renovations carried out between a house?s two sales are not accounted for in the...

The effect of credit constraints on the dropout, graduate and slow finishing decisions of university students in Australia is studied. The Australian university system has institutions in place to resolve credit constraint issues, including an income contingent loan scheme and means tested...

Concern for the Earth’s changing climate, as a consequence of rising greenhouse gas (GHG) concentrations in the atmosphere, has led to policies aimed at reducing GHG emissions and increasing carbon sequestration. In Australia this has been acknowledged in the New South Wales Greenhouse Gas...

The main purpose of this study is to provide some microeconomic tools for the calibration of a computable general equilibrium (CGE) model for Iran. For decades, CGE models have increasingly been used to study the economic and social consequences of government policy schemes and the distribution...

The Australian Parliament has passed legislation compelling tobacco products to be sold in ?plain packaging?. This paper reviews this legislation and its likely effects on prices, market structure in the tobacco industry and on smoking behaviour. Industry changes following two previous sets of...

This paper performs a comparison of two well known approaches for modelling R&D spillovers associated with investment in green technology, namely D?Aspremont-Jacquemin and Kamien-Muller-Zang. We show that there is little qualitative difference between the models in terms of total surplus...
