In this paper the scope of Bergstrom's (1982) results is studied. Moreover, his analysis is extended assuming that extraction cost is directly related to accumulated extractions. For the case of a competitive market it is found that the optimal policy is a constant tariff if extraction is...

We study sequential and single-round uniform-price auctions with affiliated values. We derive symmetric equilibrium for the auction in which k1 objects are sold in the first round and k2 in the second round, with and without revelation of the first-round winning bids. We demonstrate that...

If buyers do not observe the quality of a product and production of quality is costly, market allocations can be very inefficient. Certification intermediaries are institutions that provide information about quality to buyers. The amount of information in the market determines the incentives...

We investigate the determinants of executive pay in a sample of Italian firms. To the best of our knowledge this is the first study on the compensation of Italian executives. We estimate that an increase of real profits per firm by 1 billion lire increases the pay of top executives by only 504...

In this paper we extend a model by A. Ulph (1997) on the relationship between free trade agreements, environmental regulation and trade under imperfect competition. Ulph's model focused on the effectiveness of harmonisation policies against ecological dumping. It turned out that harmonised...

Voluntary agreements with industry offer many examples of overcompliance with respect to environmental standards. Such phenomena seem to be irrational but appear less surprising considering firms' strategies are aimed to internalise environmental quality. We model the choice of the environmental...

In this paper we analyse a common agency model in which agents can choose with how many principals they want to work, while principals cannot condition contracts on the agent's decision to accept other contracts. In this case of "non-intrinsic" common agency we characterise the equilibrium....

This paper addresses the question of delegation in an organisation where there is an initial asymmetry of information between the principal and the agent. We assume that the principal cannot use revelation techniques à la Baron Myerson to elicit agent's superior information and in contrast, we...

The Clean Development Mechanism (CDM) offers abatement cost savings under the Kyoto Protocol by allowing credits for emission reductions obtained in signatory developing countries. The paper shows that it is necessary to include technology transfers in the CDM to obtain correct incentives for...

The paper models the combined use of taxation and voluntary agreements when there is asymmetric information between the regulator and industry on the firms' actual emissions. The model incorporates the following features: 1) the regulator does not know the firm's special production...
