We combine general equilibrium theory and théorie générale of stochastic processes to derive structural results about equilibrium state prices. JEL Classification: D51, D91, G10, G12

We examine in detail the circumstances under which reciprocity, as defined in Bagwell and Staiger (1999), leads to fixed world prices. We show that a change of tariffs satisfying reciprocity does not necessarily imply constant world prices in a world of many goods and countries. While it is possible to find tariff reforms that are consistent with both reciprocity and constant world prices (as B...

as a result of higher crude oil prices, in one hand, it is expected that alternative energy resources consumption is increased and consumers change their behavior to decline energy intensity too. on the other hand, more alternative energy consumption can leads to a decline of crude oil aggregate demand. therefore, existence of mutual causality between crude oil price and alternative energy cons...

We examine the role low-price guarantees allegedly play in supporting supracompetitive prices. We find that when firms can commit to matching or beating any lower price announced by a competitor, all Nash equilibria yield Bertrand selling prices. This result casts doubt on the robustness of the conclusions of models which restrict attention to meet-the-competition clauses only. JEL Classificati...

Persistent high food prices have drawn renewed attention to the role of China in world food markets. There is concern that China will be unable to keep expanding its food supply to meet growing demand for meat, becoming more dependent on world food markets and driving prices even higher. This article reviews achievements made by China’s agriculture and highlights key challenges faced by that co...

The optimal design of input prices is analyzed in a simple setting where the regulator has limited knowledge of efficient production costs. Under some conditions, input prices are optimally set equal to expected efficient production costs, as under the Federal Communications Commission’s TELRIC pricing policy in the U.S. telecommunications industry. More generally, input prices optimally reflec...

Corporate sports sponsorship is an important part of many companies’ corporate communication strategy. We take the example of major football tournaments to show that sponsorship indeed affects the sponsor’s (stock) market value. We find a statistically significant impact of football results (at an individual game level) of the seven most important football nations at European and World Champion...

Increased competition for viewers’ time is threatening the viability of publicservice broadcasters (PSBs) around the world. Changing regulations regarding advertising minutes might increase revenues, but little is known about the structure of advertising demand. To address this problem, we collect a unique dataset on monthly impacts (quantities) and prices of UK television channels between 2002...

Information asymmetry between sellers and buyers often impedes socially desirable trade. This paper presents a new mechanism that mitigates the inefficiencies caused by information asymmetry. It is shown that markets under severe adverse selection can be endogenously segmented and such segmentation improves social welfare. Endogenous segmentation is driven by low-quality sellers’ incentive to a...

We discuss a Lévy multivariate model for financial assets which incorporates jumps, skewness, kurtosis and stochastic volatility. We use it to describe the behavior of a series of stocks or indexes and to study a multi-firm, value-based default model. Starting from an independent Brownian world, we introduce jumps and other deviations from normality, including non-Gaussian dependence. We use a ...
