The robustness of the independent private value model in Bayesian mechanism design

Summary. In a Bayesian model of group decision-making, dependence among the agents' types has been shown to have a beneficial effect on the design of incentive compatible mechanisms that achieve the efficient choice associated with complete information. This effect is shown here to depend as much upon the use of large monetary transfers among the agents as it does upon dependence: if the transfers are bounded in magnitude, then nonexistence in the case of independence of an efficient, incentive compatible, ex ante budget-balanced and interim individually rational mechanism is robust to the introduction of a small amount of dependence among types. This robustness result supports the use of the simplifying assumption of independence in mechanism design. Received: October 28, 1996; revised version: May 28, 1997

Excise Tax Harmonisation in Australia at Federation

Constitutional changes at the time of Federation in Australia required the harmonisation of the excise tax rates of the former Colonies. This paper outlines the excise tax systems of the Colonies before Federation and that of the Commonwealth after Federation. Estimates are made of the consumer tax equivalent rates and of the implicit rates of protection in each Colony and in the Commonwealth after Federation. The Commonwealth Government harmonised the excise tax rates of the Colonies at about the mid‐points of the rates of the Colonies but the implicit rates of protection increased after Federation.

Quo vadis Euro?

This paper calculates the equilibrium exchange rates for the Euro and the rest of the G-7 currencies. Building on the methodology of Alberola et al., it is shown that the stock of net foreign assets and the evolution of productivity are the fundamentals underlying the behaviour of the real exchange rate. Panel cointegration techniques allow for the extraction, using an unobserved components methodology, of a time-varying equilibrium real exchange rate, and deviations from this equilibrium provide an estimate of the degree of multilateral misalignment. Finally, an algebraic transformation converts these multilateral equilibrium real rates into bilateral equilibrium nominal rates. The results uncover that the Euro was slightly undervalued by the start of Stage III of EMU and that, despite a faint fall of its fundamentals since then, the slide during 1999 has widened the misalignment above 10% against other main currencies.     

How economic rewards affect cooperation reconsidered

Recent studies suggest that payoffs in cents, compared to dollars, produce less defection in a repeated prisoner’s dilemma game. We are unable to replicate these findings with conventional economic procedures or in a direct replication.
