We take a general model of externalities matching the Cooper & John framework with identical agents. If each agent's payoff depends on a parameter interpreted as the favourableness of the environment, we explore how the number of Nash equilibria varies with this parameter, especially in the...

We consider the comparative statics of consumer demand when there are consumption externalities in one commodity between two individuals. We show that the externality can switch goods which would naturally be normal into inferior goods and as a result th e externality can also lead to Giffen...

We take a class of games with two players and two actions which only have mixed strategy Nash equilibria. We show that such games can only have hybrid equilibria if played sequentially with one player moving first. The hybrid equilibrium has the leader p laying a mixed strategy but the follower...

The interaction between housing wealth, the financial portfolio of the consumer and consumption is a live issue. Life cycle models with closed form solutions under uncertainty are hard to find. In this paper we find analytical solutions for the effects of house price uncertainty and employment...

We consider the interaction between the risk of unemployment, random house prices, consumption and savings. A critical decision is that of refinancing house purchase, up to 100% mortgages are possible. There is also a fixed transaction cost of refinancing. In a CARA framework we derive the value...

This paper first develops a structural micro-founded model of aggregate net migration flow using matching ideas to study how migrants choose between multiple locations using multiple criteria. Migration should reduce inequality in the criteria. Most migration models either do not handle multiple...

Purpose: The purpose of this paper is to demonstrate how upstream social marketing may benefit from social media citizensourcing and improve understanding of community preferences and attitudes to policy. Using the case of shark management in New South Wales, Australia, this paper aims to...
