Voting over informal risk-sharing rules

People vote over risk-sharing rules to cope with random revenues. Risk-sharing rules are enforced through peer pressure : those who comply exert a negative externality on those who do not. People are differently affected by this externality. The author determines the elected risk-sharing rules and the level of compliance. It turns out that full risk-sharing is achieved only if everybody complies. Partial risk-sharing is more often achieved with, sometime, some level of non-compliance. In many cases, a majority of people votes over and complies with the risk-sharing rule that maximizes their own expected payoff.RISK SHARING; MUTUAL INSURANCE; ENFORCEMENT; PEER PRESSURE; POLITICAL ECONOMY

A Theory of Authority in Bilateral Contracting

Two players are involved in a joint project during which a decision must be reached. Each player has private information about future profits. Authority gives one player the right to decide first in a pre-defined set of alternatives. In this framework, I show that (partial) authority should be assigned to the player who gets the highest share of the total surplus. This organizational architecture replicates the performance of an optimal revelation mechanism without the cost of hiring a third party acting as a principal.Contract, asymmetric information, control rights, limited liability, hidden information

On the governance of start-ups

This paper examines an entrepreneur-investor relationship in a stylized model where (i) investment needs are unknown ex ante and arise sequentially (ii) a major decision must be reached at a maturity strage, (iii) this decision depends on entrepreneur's private information, observable by the investor at some cost. The two partners agree on a corporate governance system which includes a split of futre cash-flows and an allocation of control on the above decision contingently on investment. It turns out that control is assigned to the entrepreneur for low investment levels and then switches to the investor when investment exceeds a threshold.

Sequential communication with ex post participation constraints

The paper examines the implementation of Bayesian allocation rules that satisfy non-negative ex post payoffs for one player in a two-players bilateral asymmetric information setting. It focuses on sequential mechanisms in which players communicate in turn among themselves. First, it shows that, under general conditions, any such allocation rule can be equivalently implemented by a sequential mechanism. Second, when allocation rules are negotiated ex ante, the order matters. The player who communicates first must have bargaining power of unbouded ex post payoffs.

Electricity Production with Intermittent Sources

The paper analyzes the interaction between a reliable source of electricity production and intermittent sources such as wind or solar power. We first characterize the first-best dispatch and investment in the two types of energy. We put the accent on the availability of the intermittent source as a major parameter of optimal capacity investment. We then analyze decentralization through competitive market mechanisms. We show that decentralizing first best requires to price electricity contingently on wind or solar availability. By contrast, traditional meters impose a second-best uniform pricing, which distorts the optimal mix of energy sources. Decentralizing the either cross-subsidy from the intermittent source to the reliable source of energy or structural integration of the two types of technology.

On the redistributive impact of privitazing a resource under imperfect enforcement

We consider the redistributive effects of privatizing a resource previously exploited under free access. We assume that illegal extraction is punished but that the sanction is bounded by individual's wealth. First, we show that a segment of intermediate-wea lth individuals is the most adversely affected from the regime change, while the poorest segment is not only less severely affected, but may actually gain from it. Next, we show how the authorities may prefer to choose an intermediate enforcement level in order to maximize the political acceptability of the regime switch among the local community.PROPERTY RIGHTS; ENFORCEMENT; WEALTH DISTRIBUTION; NATURAL RESOURCES; ILLEGAL EXTRACTION

Roscas as Financial Agreements to Cope with Social Pressure

In developing countries, traditional social obligations often press rich individuals to share their income. In this paper, we posit a "model of social pressure" in which people can sign binding financial agreements amongst themselves, thereby forming coalitions. These financial agreements may help them to alleviate their social obligations with respect to income sharing. In the above context, we show that there exists a stable structure of coalitions in which people form rotating savings and credit associations (roscas). We therefore provide a rationale for one of the most prevalent and puzzling financial institutions.Roscas, Social pressure, Stability, Contract, Credit
