An indifference result concerning collusion in spatial frameworks

Using a general spatial model with two firms interacting repeatedly, we show that the condition for collusion sustainability is the same under uniform delivered pricing, discriminatory delivered pricing and discriminatory f.o.b. pricing.     

Forward trading and collusion in oligopoly

We consider an infinitely repeated oligopoly in which at each period firms not only serve the spot market by either competing in prices or quantities but also have the opportunity to trade forward contracts. Contrary to the pro-competitive results of finite-horizon models, we find that the possibility of forward trading allows firms to sustain collusive profits that otherwise would not be possible to achieve. The result holds both for price and quantity competition and follows because (collusive) contracting of future sales is more effective in deterring deviations from the collusive plan than inducing the previously identified pro-competitive effects.     

Market collusion and the politics of protection

This paper investigates the relationship between trade and competition policy within a model where market collusion and protectionist lobbying are themselves related. Collusion and lobbying are modeled as joint products of the same collective effort of firms. In equilibrium, firms cannot achieve greater cooperation in one dimension without reducing it in the other. A trade agreement that limits the effectiveness of lobbying may cause firms to increase market collusion, thereby increasing the domestic price. Thus, international trade agreements may run counter to the goals of competition policy. On the other side, a more restrictive competition policy is shown to either reduce the domestic price or reduce import protection. Thus, competition policy tends to promote trade policy goals. The reason is that restrictive competition policy undermines collusion at the source—it decreases the per-firm benefit to collusion relative to the gains from deviating—reducing firm cooperation in both dimensions.     

A theory of collusion with partial mutual understanding

Unlawful collusion is when firms have a mutual understanding to coordinate their behavior for the purpose of achieving a supracompetitive outcome. Given the legal focus on mutual beliefs, this paper explores the role of mutual beliefs in producing collusion. Focusing on price leadership, firms are assumed to commonly believe that price increases will be at least matched but lack any shared understanding about who will lead, when they will, and at what prices. Sufficient conditions are derived which ensure that supracompetitive prices emerge. However, price is bounded below the maximal equilibrium price.     

Comparing competition and collusion: a numerical approach

Summary. Collusion is a serious problem in many procurement auctions. In this research, I study a model of first price sealed bid procurement auctions with asymmetric bidders. I demonstrate that the equilibrium to the model is unique and describe three algorithms that can be used to compute the inverse equilibrium bid functions. I then use the computational algorithms to compare competitive and collusive bidding. The algorithms are useful for structural estimation of auction models and for assessing the damages from bid-rigging. Received: January 14, 2000; revised version: February 28, 2001     

Backward integration and collusion in a duopoly model with asymmetric costs

This paper formalizes the idea that input transactions might be used to implement side payments among colluding firms. A model is proposed to analyze the effect of backward integration on collusive outcomes in a downstream duopoly with asymmetric marginal costs. Vertical integration expands the set of collusive outcomes that are sustainable for a given realization of the discount factor. This is an additional effect of vertical integration that antitrust authorities should consider. Side payments implemented by input sales are more relevant the larger the difference in marginal costs, since they allow for the shifting of production towards the relatively more efficient firms, while maintaining firms’ incentives to collude. A price of the input above that posted by an alternative source or sales of the input below cost may be observed, depending on the realization of downstream firms’ costs.      

A note on cartel stability and endogenous sequencing with tacit collusion

We use the concept of cartel stability defined by d’Aspremont et al. (Can J Econ 16(1):17–25, 1983) to obtain that the sequence of play between the cartel and the fringe affects cartel stability in a quantity-competition setting where firms tacitly collude. We also prove that an endogenous sequence of play between a cartel and a fringe depends on the discount factor. If the discount factor is large enough, the cartel and the fringe simultaneously choose quantities since the stable cartel may contain more firms under simultaneous play than under cartel leadership. This is due to the fact that under simultaneous play cartel firms have incentives to participate in the cartel because otherwise no collusion is possible.      

Can self regulation work?: a story of corruption,impunity and cover-up

This paper analyzes the reputation-based incentives of a Self-Regulatory Organization (SRO) to detect and expose consumer fraud committed by its members, and the members’ incentives to bribe the SRO in exchange for a cover-up to avoid an external punishment. In a corruption-free benchmark, SROs are effective in detecting, exposing and deterring fraud only if exposure yields a reputation gain to the SRO, which depends on consumers inferences about the SRO’s type. However, if this case prevails the member can succeed in bribing the SRO in exchange for a cover-up and impunity. Despite this, a bribed SRO yields more vigilance and lower fraud than no self-regulation at all.      

R & D joint ventures and tacit product market collusion

It is shown that R & D joint ventures make it more likely that firms will be able to sustain tacit product-market collusion, all else equal.     

The neglected effects of demand characteristics on the sustainability of collusion

According to standard IO models, the parameters that characterize market demand (intercept, slope, and elasticity) and technology (the level of symmetric marginal costs) do not play any role in defining the sustainability of collusive behaviors in Bertrand oligopolies. This paper modifies this counterintuitive result by showing that all of the aforementioned factors do indeed matter when prices are assumed to be discrete rather than continuous. The sign of these effects is clear. Their magnitude varies greatly; i.e., in some cases, it is totally negligible, while in others, it becomes extremely relevant.     

The impact of liberalization on bureaucratic corruption

Liberalization increases the number of goods available for consumption within a country. Since bureaucrats value variety, this raises the marginal utility of accepting a bribe. This “benefit effect” is counteracted by an increasing “cost effect” from corruption deterrence activities that arise due to greater international pressure to curb corruption. The interaction of these two effects can lead to a non-monotonic relation between liberalization and corruption. Moreover, pre-commitment to deterrence activities is shown to be more effective in controlling corruption. Empirical evidence supports the existence of a non-monotonic relation between economic openness and corruption among developing countries.

Crime and corruption in transitional economies: lessons for Cuba

Trends in aggregate crime rates across Europe reveal significant increases in crime in transitional countries. We identify causal mechanisms associated with the economic transition. Historical experience of corruption in the Soviet Union is reviewed, and connections between corruption and transition are analyzed. We apply the results to Cuba's current circumstances, examining the potential for growth in crime and corruption in Cuba and suggesting policies to ameliorate it.

The wealth effects of premium subsidies on moral hazard in insurance markets

Insurance premium subsidies are present in many insurance markets. The Swiss government, for example, paid out CHF 4.26 billion or 0.72% of the Swiss GDP for health insurance premium subsidies in 2011. Analyses of premium subsidies have often highlighted that the increased insurance demand due to premium subsidies increases the effects of moral hazard in the market. Other consequences of premium subsidies, however, have mostly been neglected by the literature. We show in our theoretical model that the wealth effects of premium subsidies decrease the sensitivity of the insured towards the monetary consequences of losses. This leads to less prevention efforts by the insured and thus increases moral hazard in the market. The effect is preserved if the subsidy is financed through proportional taxation. Using two alternative models, we show that providing state-dependent subsidies can either increase or reverse this effect, depending on which state subsidies are paid. We argue that whether demand effects or wealth effects of premium subsidies will dominate the insured׳s behavior depends on the market structure.     

Contests to become CEO: incentives, selection and handicaps

Should a firm favor insiders (handicap outsiders) when selecting a CEO? One reason to do so is to take advantage of the contest to become CEO as a device for providing current incentives to employees. An important reason not to do so is that this can reduce the ability of future CEOs and, hence, future profits. The trade-off between providing current incentives and selecting the most able individual to become CEO is the focus of this paper. If insiders are good enough (better or nearly as good as outsiders), incentive provision to insiders typically dominates and it is optimal to handicap outsiders, sometimes so severely that they have no chance to win the contest. However, if outsiders are sufficiently better than insiders, selection dominates and it is the insiders who are severely handicapped. This finding is in sharp contrast to the existing literature which has so far ignored this trade-off. In all, our model provides useful insight into contests to become CEO and rationalizes empirical regularities in the source of CEOs chosen by firms. In particular, our analysis helps to explain the lower tendency of firms in more heterogeneous industries and firms with a product or line of business organizational structure to select an outsider as CEO.     

Asymmetric awareness and moral hazard

This paper introduces asymmetric awareness into the classical principal–agent model and discusses the optimal contract between a fully aware principal and an unaware agent. The principal enlarges the agentʼs awareness strategically when proposing a contract and faces a tradeoff between participation and incentives. Leaving the agent unaware allows the principal to exploit the agentʼs incomplete understanding of the world, relaxing the participation constraint, while making the agent aware enables the principal to use the revealed contingencies as signals about the agentʼs action choice, relaxing the incentive constraint. The optimal contract reveals contingencies that have low probability but are highly informative about the agentʼs effort.     

反洗钱国际合作与犯罪资产分享问题研究

洗钱犯罪具有诸多上游犯罪,腐败犯罪是其中之一。腐败犯罪,特别是跨国腐败犯罪,日益演化成为跨国洗钱犯罪。犯罪行为人利用国际金融快速便捷的汇兑工具,实施转移腐败赃款的活动。通过跨国洗钱活动,可以使犯罪分子获取大量的现金,并进而从事经营活动,聚敛更多的非法财产,获取更多的经济资源,从而为进一步实施腐败活动提供经济支持。为此,国际社会给予高度重视,在腐败资产追回和预防腐败资产转移目标下,探讨反洗钱国际合作,以及犯罪资产分享等理论和实践问题,为腐败资产追回和预防腐败资产转移探索国际合作途径,提高反腐败国际合作成效提供方法上的参考。我国为研究实施《联合国反腐败公约》,投入较大的精力,成立了国家预防腐败局,并广泛开展反腐败国际合作,推动实施《联合国反腐败公约》的步伐。本文就围绕以上问题,从反腐败国际合作实践角度,运用实证思考方法加以研究,以期为反腐败调查、追回腐败资产、开展反洗钱合作提供总结与建议性思想材料。     

Coexistence of long-term and short-term contracts

We study the length of agreements in a market in which infinitely-lived firms contract with agents that live for two periods. Firms differ in the expected values of their projects, as do workers in their abilities to manage projects. Worker effort is not contractible and worker ability is revealed during the relationship. The market dictates the trade-off between sorting and incentives. Short- and long-term contracts often coexist: The best firms always use short-term contracts to hire high-ability senior workers, firms with less profitable projects use short-term contracts to save on the cost of hiring junior workers, whereas intermediate firms use long-term agreements to provide better incentives to their workers. We relate our results to the optimal assignment literature that follows Becker (1973).     

Team production with inequity-averse agents

This paper analyzes the efficiency of team production when risk-neutral agents exhibit other-regarding preferences. It is shown that full efficiency can be sustained as an equilibrium of a budget-balancing mechanism that punishes some randomly chosen agents if output falls short of the efficient level but distributes output equally otherwise. The result depends on agents being sufficiently inequity-averse.
