In practice, central banks have been confronted with a trade-o¤ between stabilising in‡ation and output when dealing with rising oil prices. This contrasts with the result in the standard New Keynesian model that ensuring complete price stability is the optimal thing to do, even when an oil shock leads to large output drops. To reconcile this apparent contradiction, this paper investigates how ...

We conducted preference assessments with 4 typically developing children to identify potential reinforcers and assessed the reinforcing efficacy of those stimuli. Next, we tested two predictions of economic theory: that overall consumption (reinforcers obtained) would decrease as the unit price (response requirement per reinforcer) increased and that the cost and benefit components that defined...

An auction of carbon permits is the best way to achieve carbon caps set by international negotiation to limit global climate change. To minimize administrative costs, permits would be required at the level of oil refineries, natural gas pipe lines, liquid sellers, and coal processing plants. To maximize liquidity in secondary markets, permits would be fully tradable and bankable. The government...

We introduce and study a new auction model in which a certain type of goods is offered over a period of time, and buyers arrive at different times and stay until a common deadline (unless their purchase requests have been fulfilled). We examine in this model incentive compatible auction protocols (i.e., those that induce participants to bid their true valuations). We establish an interesting co...

We develop an aggregative games approach to study oligopolistic price competition with multiproduct firms. We introduce a new class of IIA demand systems, derived from discrete/continuous choice, and nesting CES and logit demands. The associated pricing game with multiproduct firms is aggregative and a firm’s optimal price vector can be summarized by a uni-dimensional sufficient statistic, the ...

This paper develops a view of exchange rate policy as a trade-off between the desire to smooth fluctuations in real exchange rates so as to reduce distortions in consumption allocations, and the need to allow flexibility in the nominal exchange rate so as to facilitate terms of trade adjustment. We show that optimal nominal exchange rate volatility will reflect these competing objectives. The k...

A long literature since Feldstein and Horioka’s seminal contribution documents the strong correlation of domestic saving and investment rates since the 1960s. According to conventional wisdom, the result provides evidence of international capital market imperfections. The macroeconomic theory of small open economies prescribes a relationship between the composition of aggregate demand and its r...

THE TIMELINESS AND CONTINUING RELEVANCE OF AUSTRIAN BUSINESS CYCLE THEORY Careful study of the book under review is a rewarding experience. As Roger Garrison points out in the Foreword (pp. iii–vii), Austrian capital-based business cycle theory has lost nothing of its relevance and timeliness. The theory identifies monetary mismanagement as a major source of economywide distortions in the inter...
