Implementing just and efficient decision-making

In an economy with one public good, one private good and quasi-linear utilities we explore decision-making mechanisms to non-cooperatively implement an efficient outcome. By auctioning the leadership role among agents, one implements egalitarianism, namely the efficient outcome that distributes equally the surplus available from an a priori given status quo. A refinement of this mechanism (so-called autioning the leadership with differentiated buds) allows us to implement an efficient anonymous and neutral outcome: it achieves egalitarianism above the Vickrey-Clarke-Groves decision.     

Nothing like the Enron affair could happen in France (!)

Abstract

This paper reviews the reactions of the French accounting profession and academia following the collapse of both Enron and Andersen. It considers policy statements and declarations on the part of the accounting profession, legislative changes, the general impact on university accounting education programmes and specific developments in accounting teaching at my own institution, HEC. It considers the value of using corporate scandals in the teaching process and claims that more accounting theory and ethical issues should be introduced in accounting educational programmes.     

Extent and possible causes of intrayear agricultural commodity price volatility

Wheat, corn, rice, soybeans, and cotton experienced higher volatility in the second half of the 2000s. For the sample at hand, the unit root tests only validate a new period of high volatility for wheat and cotton. If in the next couple of years however, corn, rice and soybeans maintain their higher volatility, a new period of high volatility may also be validated statistically. Regarding the factors driving the intrayear volatility GMM estimates show that “commodity market fundamentals” i.e., the stock‐to‐use ratio and to a lesser extent the degree of internationalization, are the most systematically statistically significant coefficients among commodities. Over time, consecutive low stock‐to‐use ratios and a thin international market provoke typically high volatility. Speculative activity and liquidity in the agricultural derivative market have a stabilizing effect on the spot price, if any. Finally, “common macro” factors significantly impact volatility, especially the volatility of petrol and of exchange rates; their dispersion importance over the sample is quite sizeable. However, it is difficult to establish a link between, on the one hand, loose monetary policy, business cycle and inflation, and, on the other hand, commodity price volatility, as the sign of the estimated coefficient changes depending on the commodity and the estimated elasticities are quite low.     

Implementing and interpreting indicators of core inflation: the case of France

This paper presents a comparison of alternative indicators of underlying or “core” inflation in the French case. Four broad measures are considered and implemented. The first two are inflation excluding food and energy, and the trimmed inflation indicator. We then implement two methods relying on time-series models: the Dynamic Factor Index and the structural VAR approach.  Each indicator stresses on a particular type of shock on the inflation rate, so that no simple ranking of the measures emerges. Combining the various indicators conveys valuable information for appraising short term inflation developments. As regards theoretical interpretation, no indicator is fully satisfactory, lacking an explicit representation of monetary policy. However, comparing forecast performance with respect to inflation provides some specific support in favor of trimmed mean indicators.

Manipulation-proof equilibrium in atomless economies with commodity differentiation

Summary. In this paper, we introduce a perfect competition test which checks the incentives of arbitrarily small coalitions to behave strategically in endowments and preferences. We apply this coalitional incentive compatibility test to atomless economies with a continuum of differentiated commodities. We show that, under thickness conditions, economies with a finite number of types and economies whose set of agents' preferences is compact, pass this perfect competition test. Limiting results for replica economies are also presented. Received: July 25, 1997; revised version: December 5, 1998
