On the sufficiency of regulatory enforcement in combating piracy

The literature on piracy has questioned the role of regulatory enforcement in the form of monitoring in deterring piracy. This article shows that for a wide range of penalty levels the equilibrium monitoring rate is such that it is optimal for the copyright holder to prevent piracy by expanding his output beyond the monopoly output level rather than producing the monopoly output level and investing in an anticopying technology. This result holds even when the monitoring cost is “sufficiently” high relative to the cost of investing in anti-copying technology.     

Environmental regulatory enforcement with “green” consumers

We consider a standard probabilistic model of random monitoring to analyze the interactions between a firm and a monitoring agency in the presence of “green” consumers when compliance payoffs are contingent on monitoring and monitoring costs are shared by the monitoring agency and the firm. When the amount paid by the firms if monitored is exogenously fixed, we find that full compliance is implemented with a finite fine. If there is an upper bound for the fine and the regulator determines endogenously the fine and the amount paid by the firms if monitored, we find that full compliance is also achieved, although the optimal fine is now set at its maximum level. The optimal amount paid by the firms if monitored is lower than the environmental premium the compliant firm gets.The author thanks two anonymous referees for their useful comments and suggestions     

Social Desirability of Earnings Tests

Abstract. In many countries, pension systems involve some form of earnings test; i.e. an individual's benefits are reduced if he has labor income. This paper examines whether or not such earnings tests emerge when pension system and income tax are optimally designed. We use a simple model with individuals differing both in productivity and in their health status. The working life of an individual has two 'endings': an official retirement age at which he starts drawing pension benefits (while possibly supplementing them with some labor income) and an effective age of retirement at which professional activity is completely given up. Weekly work time is endogenous, but constant in the period before official retirement and again constant (but possibly at a different level), after official retirement. Earnings tests mean that earnings are subject to a higher tax after official retirement than before. We show under which conditions earnings tests emerge both under a linear and under a non-linear tax scheme. In particular, we show that earnings tests will occur if heterogeneities in health or productivity are more significant after official retirement than before.     

Contract enforcement in sellers' markets

I present an infinitely repeated game model where a monopolist seller has a contractual obligation with several buyers in each period. If a contract is violated the buyer can collect some compensation and impose a penalty on the seller. There are an infinite number of subgame perfect equilibria in this model, but I employ the concept of e-validated equilibrium to pick out a unique equilibrium outcome for the game where the seller is able to dominate the buyers. This model is clearly applicable to supply problems of Soviet-type economies, but it can explain certain phenomena of Western economies as well.     

Quasi-weightings, Trading, and Desirability Relations in Simple Games

We investigate the problem of simultaneously characterizing various classes of simple games in three different ways: (i) the existence of “quasi-weightings” in which smaller numerical values are assigned to losing coalitions than are assigned to winning ones, (ii) the robustness of “winningness” with respect to trades involving groups of players, and (iii) the acyclicity of certain strict “orderings” that intuitively correspond to the idea of one player being more desirable than another.Journal of Economic LiteratureClassification Number: C71.     

Campaign Contributions and the Desirability of Full Disclosure Laws

In a signaling game model of costly political campaigning in which a candidate is dependent on a donor for campaign funds it is verified whether the electorate may benefit from campaign contributions being directly observed. By purely focusing on the informational role of campaign contributions the model seems somewhat biased against the potential benefits of direct observation. Still, the conclusion can be drawn that directly observable contributions allow for more information being revealed in equilibrium. Using this result, from an informational perspective a case can be built for the desirability of full disclosure laws.     

The effect of EPA enforcement funding on private-sector pollution-control investment

The paper estimates the effects of the US Environmental Protection Agency (EPA) enforcement budget upon the demand for pollution-control equipment in the private sector. There are two possible effects. A direct effect occurs when the enforcement budget is used for inspections that result in enforced compliance requiring additional pollution control equipment. A second effect is anticipatory, and arises from the private sector's objective of minimizing expected costs due to fines imposed by the EPA for infractions of pollution-control requirements. This component of demand depends, in part, on the EPA enforcement budget. We find that increases in the EPA budget increase the demand for pollution-abatement equipment. This in turn implies that increases in the EPA enforcement budget have been effective in mitigating pollution.     

The effects of employment protection: Learning from variable enforcement

Employment protection legislation (EPL) is not enforced uniformly across the board. There are a number of exemptions to the coverage of these provisions: firms below a given threshold scale and workers with temporary contracts are not subject to the most restrictive provisions. This within-country variation in enforcement allows us to make inferences on the impact of EPL which go beyond the usual cross-country approach. In this paper we develop a simple model which explains why these exemptions are in place to start with. Then we empirically assess the effects of EPL on dismissal probabilities and on the equilibrium size distribution of firms. Our results are in line with the predictions of the theoretical model. Workers under permanent contracts in firms with less restrictive EPL are more likely to be dismissed. However, there is no effect of the exemption threshold on the growth of firms.     

The competitive enforcement of property rights in medieval Japan: The role of temples and monasteries

Medieval Japanese governments only haphazardly enforced claims to scarce resources. Necessarily, this presented landholders with a void. To obtain the enforcement they needed, many turned to institutions affiliated with the fractious Buddhist faith instead. Temples and monasteries enjoyed an exemption from tax on their lands and controlled an array of financial and human resources with which they could adjudicate and enforce claims to scarce resources. To obtain access to that exemption and those resources, landholders “commended” their rights in land to them, and paid them a share of the harvest. In exchange, the temples and monasteries exempted them from tax, adjudicated disputes internal to the estate and protected their estates against external threats. Effectively, the temples and monasteries competed in a market for basic governmental services.By helping to secure basic claims to property, the temples and monasteries helped to promote investment and growth; by competing against the government itself, they helped to forestall the crippling effect of a predatory monopolistic state.     

On the Social Desirability of Patents for Sequential Innovations in a Vertically Differentiated Market

We consider a market for vertically differentiated goods where firms enter over time, after having developed innovations characterised by different quality levels. We show that patent height and length interact to determine the ultimate emergence of duopoly. In general, imposing quality improvements on later entrants entails the persistence of monopoly, while a duopoly equilibrium emerges when the second innovator is allowed to produce a sufficiently inferior quality and the patent protection granted to the first innovator is not too long-lasting.     

Desirability bias in foresight: Consequences for decision quality based on Delphi results

In foresight activities uncertainty is high and decision makers frequently have to rely on human judgment. Human judgment, however, is subject to numerous cognitive biases. In this paper, we study the effects of the desirability bias in foresight. We analyze data from six Delphi studies and observe that participants systematically estimate the probability of occurrence for desirable (undesirable) future projections higher (lower) than the probability for projections with neutral desirability. We also demonstrate that in the course of a multi-round Delphi process, this bias decreases but is not necessarily eliminated. Arguably, the quality of decisions based on Delphi results may be adversely affected if experts share a pronounced and common desirability for a future projection. Researchers and decision makers have to be aware of the existence and potential consequences of such a desirability bias in Delphi studies when interpreting their results and taking decisions. We propose a post-hoc procedure to identify and quantify the extent to which the desirability bias affects Delphi results. The results of this post-hoc procedure complement traditional Delphi results; they provide researchers and decision makers with information on when and to which extent results of Delphi-based foresight may be biased.     

Lie aversion and self-reporting in optimal law enforcement

Requirements that individuals or companies self-report violations are common in regulation and law enforcement. This paper studies how violators’ aversion to lying affects the design and merit of enforcement regimes that require self-reporting. Even when a self-reporting requirement produces costs of lies and enjoys no economic advantage in the absence of lie aversion, I find that self-reporting improves enforcement efficiency. With lie aversion, self-reporting enables greater deterrence of violations at a lower cost of monitoring. Corollaries to this result are that (1) the presence of lie aversion enhances social welfare; (2) enforcement regimes that elicit more noxious lies when false reports are made—for example, a compulsory versus voluntary self-reporting feature—are advantageous; and (3) under an optimal enforcement regime, lying generally occurs and the self-reporting sanction is higher than the average sanction for a false report.     

The impact of the judicial objective function on the enforcement of environmental standards

We investigate the influence of a judge’s objective function on the type of sanctions used for enforcing environmental standards. We focus on the difference between monetary and non-monetary penalties. We examine the extent to which judges take social costs of sanctions into account when making judgments in court in the context of environmental violations. We also conduct an empirical analysis to test the main findings of the theoretical model using court data from several Belgian jurisdictions. We find that besides minimizing environmental damages judges also take social costs of sanctions into account in their decision-making.     

Bonding and the enforcement of labor contracts

Bonded contracts are a perfect substitute for legally enforceable contracts, if capital markets are perfect. This idea is applied to labor market contracts involving specific training.

The regulatory choice of noncompliance in emissions trading programs

This paper addresses the following question: To achieve a fixed aggregate emissions target cost-effectively, should emissions trading programs be designed and implemented to achieve full compliance, or does allowing a certain amount of noncompliance reduce the costs of reaching the emissions target? The total costs of achieving the target consist of aggregate abatement costs, monitoring costs, and the expected costs of collecting penalties from noncompliant firms. Under common assumptions, I show that allowing noncompliance is cost-effective only if violations are enforced with an increasing marginal penalty. However, one can design a policy that induces full compliance with a constant marginal penalty that meets the aggregate emissions target with lower expected costs. This last result does not depend on setting an arbitrarily high constant marginal penalty. In fact, the marginal penalty need not be higher than the equilibrium marginal penalty under the policy with the increasing marginal penalty, and can actually be lower. Finally, tying the marginal penalty directly to the permit price allows the policy objective to be achieved without any knowledge of firms’ abatement costs.     

浅析执行和解的适用

执行和解就其性质而言,应当属于民事处分行为,是执行权利人行使处分权的结果,是民事诉讼法规定的处分原则在执行程序中的具体体现.在执行程序中,双方当事人有权处分自己的民事权利和诉讼权利.民事诉讼法基于当事人的权利处分原则设立了执行和解制度,在司法实践中具有重大意义.首先,有利于执行申请人的权利得以顺利实现;其次,有利于当事人之间保持良好的合作关系;最后,有利于人民法院减少执行成本.
