Rock Paper Scissors

Rock Paper Scissors is used to resolve conflict when a compromise is not possible. Individuals playing ``games' tend to have biases they prefer to play. I show that Rock Paper Scissors with biased players results in a player with a high valuation for winning being victorious with a probability greater than a player with a low valuation. Thus, it frequently achieves the efficient outcome. Furthermore, as the benefit to victory increases for all players, victory for each player becomes equally likely. Therefore, it is often efficient for minor conflicts while it performs no better than a coin-flip for major conflicts.      

Rich Nations, Poor Nations: How Much Can Multiple Equilibria Explain?

This paper asks whether the income gap between rich and poor nations can be explained by multiple equilibria. We explore the quantitative implications of a simple two-sector general equilibrium model that gives rise to multiplicity, and calibrate the model for 127 countries. Under the assumptions of the model, around a quarter of the world’s economies are found to be in a low output equilibrium. We also find that, since the output gains associated with an equilibrium switch are sizeable, the model can explain between 15 and 25% of the variation in the logarithm of GDP per worker across countries.     

THE TREATMENT OF STOCK APPRECIATION IN THE MEASUREMENT OF NATIONAL INCOME*

In the latest official national income publication the Australian Commonwealth Statistician has altered the treatment of stock appreciation in the measurement of national income at current prices. Previously, stock appreciation had been included in both national expenditure and national product. Now the amount of stock appreciation (the difference between the change in the value of stocks and the value of the change in stocks) has been deducted from investment in stocks, and consequently national expenditure, and from trading incomes, and consequently national income. The former procedure (including stock appreciation in national expenditure and national product) had been advocated by the present author, when editor of the first official national income publications issued by the Commonwealth Statistician. In this note an attempt is made to set out the reasons for this view. A new approach is also suggested for handling the item of stock appreciation in national income accounts, which does not rest on the assumption that stock appreciation is a capital gain which should be excluded from trading incomes and national product.     

South Pacific tourism in the mid-1980s

The Pacific Islands have weathered the world economic recession well, but not without changes in their approach to tourism. Poor economic conditions coupled with US airline deregulation caused considerable reassessment. The fear of recession, together with optimism concerning the future resulted in new services (while others were going out of business), a spate of hotel construction plans (even in areas with low occupancy rates) and a softening of attitudes towards tourism. The possibility of a huge Pacific Basin (Rim) market strongly influenced these development policies.     

Networks,Law, and the Paradox of Cooperation

There is a tension between libertarians' optimism about private supply of public goods and skepticism of the viability of voluntary collusion (Cowen 1992, Cowen and Sutter 1999). Playing off this asymmetry, Cowen (1992) advances the novel argument that the free market in defense services favored by anarcho-capitalists is a network industry where collusion is especially feasible. The current article dissolves Cowen's asymmetry, showing that he fails to distinguish between self-enforcing and non-self-enforcing interaction. Case study evidence on network behavior before and after antitrust supports our analysis. Furthermore, libertarians' joint beliefs on public goods and collusion are, contrary to Cowen and Sutter (1999), theoretically defensible.
