Pressure Groups and Experts in Environmental Regulation

We study a problem of adverse selection in the context of environmental regulation, where the firm may suffer from a certain degree of ignorance about its own type. In a framework like the construction of a certain infrastructure project, the presence of ignorance about its impact on the environment, can play an important role in the determination of the regulatory policy. First, an optimal contract is constructed for any exogenous level of ignorance. Second, the presence of potentially informed third-parties is studied from the perspective of the regulator, which allows us to analyze the impact on the efficiency of the contract, of the presence of environmentalists and of experts. Then, we obtain some insights on how the problem differs when the degree of ignorance is a choice variable for the firm. We finally use our results to derive policy implications concerning the existing envoronmental regulation, and the potential role of interested parties as information providers.environmental regulation, ignorance, environmentalists, experts.

Choosing High-Court Judges by Political Parties.

This paper proposes a mechanism to overcome the possibility that political parties may block the nomination of High-Court judges when the Parliament is involved in their nomination and their mandate expires on a fixed date. This possibility arises when the default option is that the judge whose mandate expires holds office until an agreement is reached. Our proposal consists of changing the default option by a weighted lottery. We show that this mechanism is capable of solving the problem and implementing the socially optimal solution.Negotiation, Political Competition, random protocols, legislative bargaining.

A Micro- Foundation for Non-Deterministic Contests of the Logit Form

In models of non-deterministic contest, players exert irreversible effort in order to increase their probability of winning a prize. The most prominent functional form of the win probability in the literature is the so-called “logit” contest success function. We provide a simple micro-foundation of this function for the two contestant case. In this setting the contest administrator is a rational decision maker whose optimal choice is deterministic. However, from the point of view of the contestants the outcome of the contest is probabilistic because of an underlying uncertainty about the type of the administrator.Contests, Contest Success Function, Effort levels, Endogenous Contest.

Side Effects of Campaign Finance Reform

Since campaign finance reform is usually motivated by the concern that existing legislation can not effectively prevent campaign contributions to ‘buy favors’, this paper assumes that contributions influence political decisions. But, given that it is also widely recognized that interest groups achieve influence by providing political decision makers with policy relevant information, we also assume that lobbies engage in non-negligible informational lobbying. We focus on a single political decision to be taken and offer a simple model in which the optimal influence strategy is a mixture of both lobbying instruments. Our main result is to show that campaign finance reform may have important side effects: It may deter informational lobbying so that less policy relevant information is available and as a result political decisions become less efficient.party and candidate financing, lobbying, interest groups, experts, information transmission, contributions, influence, political decision making process.

The Role of Mediation in Peacemaking and Peacekeeping Negotiations.

We develop a model of bargaining that provides a rationale for the difference in the method of negotiation, depending on the nature of the conflict. We distinguish those negotiations that take place previous to a potential conflict (peacekeeping), and negotiations inside the conflict (peacemaking). In these contexts, we study the role of a mediator that tries to achieve a certain balance between the efficiency of the agreement and the equality of the sharing. We show that the credibility of the mediator comes from her willingness to impose delays in the negotiation, even if that implies costs. We also find how the “weak” player in the conflict can strategically profit from the mediator’s quest for equality. Finally, we show how the capacity of the mediator to induce a higher equality in the sharing is always higher in a peacemaking situation than in a peacekeeping one..Mediation, Rubinstein bargaining.

Informational Lobbying under the Shadow of Political Pressure

We examine the incentives of an interest group to provide verifiable policy-relevant information to a political decision-maker and to exert political pressure on her. We show that both lobbying instruments are interdependent. In our view information provision is a risky attempt to affect the politician’s beliefs about the desirability of the lobby’s objective. The constraints governing informational lobbying determine a specific lottery available. The circumstances under which political pressure can be applied specify the lobby’s valuation of different beliefs of the politician and, thus, her attitude toward risk. The combination of lotteries available and induced risk preference determines the optimal lobbying behavior. Our approach gives a novel explanation for the fact that interest groups often try to provide information credibly. We identify several factors that induce risk proclivity (and thus information provision). We also show that the availability of political pressure might have a deterrence effect on information provision. This ‘shadow of political pressure’ might impede information provision at all or induce a complementary relationship between both lobbying instruments.Experts, Influence, Credibility, Political contributions, Issue ads.

Biased Contests

We examine the effects of providing more accurate information to a political decision-maker who is lobbied by competing interests. Conventional wisdom holds that such a bias in the direction of the correct decision improves the efficiency of government. We provide a formal definition of bias which is derived from the same fundamentals that give rise to a contest model of lobbying. Efficiency of government is measured by both the probability of taking the correct decision and the amount of social waste associated to lobbying activities. We present a benchmark model in which increasing the bias always improves the efficiency of government under both criteria. However, this result is fragile in the sense that reasonable alternative assumptions in the micro-foundations lead to slightly different models in which -due to different strategic effects of bias- under either criterion there is no guarantee that more accurate information improves government.Endogenous Contests, Contest Success Function, Information provision

We identify several factors that induce risk proclivity (and thus information provision), which allows to explain the stylized fact that lobbies engage both in information provision and political pressure. Moreover, our approach gives a novel explanation for the fact that interest groups often try to provide information credibly. We finally study the extent to which this preference for credibility is robust and identify some instances in which lobbies may prefer to strategically withhold information.Experts, Influence, Credibility, Political contributions, Issue ads.

New perspectives in the design of pharmaceutical copayments

In this paper we propose a new approach for the design of pharmaceutical copayments. We departure from the standard efficiency argument that advocates for copayments that are decreasing in the health benefits of the patients in order to discipline consumption. Under our approach, copayments are justified by the difficulties for the provider to fully fund their health services.pharmaceutical copayments, equity, axiomatic bargaining, claims
