We present a model of anonymous collective bargaining where individuals'preferences and information may be significantly interdependent. We showthat the bargaining outcome becomes independent of individuals'preferences and information as the bargaining group increases in size. As acorollary, we show that anonymous voluntary bargaining completely fails inlarge groups. Either the difference between the bargaining outcome and thestatus quo vanishes as the size of the group becomes larger, or, thebargaining becomes coercive and results in a violation of at least someindividuals' rights. The result provides a rationale for the inherentdifficulty of reform in the presence of asymmetric information.

Bilateral bargaining situations are often characterized by informational asymmetries concerning the size of what is at stake: in some cases, the proposer is better informed, in others, it is the responder. We analyze the effects of both types of asymmetric information on proposer behavior in two different situations which allow for a variation of responder veto power: the ultimatum and the dictator game. We find that the extent to which proposers demand less in the ultimatum as compared to the dictator game is (marginally) smaller when the proposer is in the superior information position. Further we find informed proposers to exploit their informational advantage by offering an amount that does not reveal the true size of the pie, with proposers in the ultimatum game exhibiting this behavioral pattern to a larger extent than those in the dictator game. Uninformed proposers risk imposed rejection when they ask for more than potentially is at stake, and ask for a risk premium in dictator games. We concentrate on proposers, but also explore responder behavior: We find uninformed responders to enable proposers’ hiding behavior, and we find proposer intentionality not to play an important role for informed responders when they decide whether to accept or reject an offer by an (uninformed) proposer.  相似文献

We show that in public good problems under asymmetric information, the success of voluntary bargaining is closely related to the structure of property rights. We characterize property rights structures and mediated bargaining procedures that either lead to an efficient voluntary resolution to public good problems, or achieve the efficient outcome but slightly coerce the agents into participation. In this respect, we identify "efficient" property rights structures.  相似文献

The sealed bidk-double auction is a mechanism used to structure bilateral bargaining under two-sided incomplete information. This mechanism is tested in two experiments in which subjects are asked to bargain repeatedly for 50 rounds with the same partner under conditions of information disparity favoring either the buyer (Condition BA) or seller (Condition SA). Qualitatively, the observed bid and offer functions are in agreement with the Bayesian linear equilibrium solution (LES) constructed by Chatterjee and Samuelson (1983). A trader favored by the information disparity, whether buyer or seller, receives a larger share of the realized gain from trade than the other trader. Comparison with previous results reported by Daniel, Seale, and Rapoport (1998), who used randomly matched rather than fixed pairs, shows that when reputation effects are present this advantage is significantly enhanced. A reinforcement-based learning model captures the major features of the offer and bid functions, accounting for most of the variability in the round-to-round individual decisions.  相似文献

We study a model in which the seller of an indivisible object faces two potential buyers and makes an offer to either of them in each period. We find that the seller's ability to extract surplus from them depends crucially on the value of the cost of switching from one buyer to the next. If the seller is pessimistic about the buyers' valuations and there is a switching cost, however small, then the market is a natural bilateral monopoly; the second buyer is never called on. If the switching cost is zero, or if the seller is optimistic, then switching, and possibly recall of the original buyer, may occur.  相似文献

This paper analyses a situation in which there are three quantity‐setting firms, two of which are considering whether or not to merge. When these two firms have private information about the potential cost‐saving synergies of the merger, they may have an incentive to overstate them. This is because if they succeed in making the non‐merging rival firm believe that the synergies are high, the rival firm reduces output and the merger becomes more profitable. Under some conditions, anticipating that the rival will form such a belief, low‐synergy firms that would never merge under complete information will mimic high‐synergy firms by merging. Such pooling behaviour by the merging firms can have a negative impact on social welfare.  相似文献

Regulating a Polluting Firm Under Asymmetric Information   总被引:1,自引:3,他引:1  
This paper reinterprets the Laffont-Tirole model of regulation under asymmetric information to cover the case of pollution control. The asymmetry of information concerns the firm's cost of lowering its pollution. The regulator has three objectives: Ensuring an efficient abatement level, generating 'green taxes' and securing the survival of the firm. We show that when optimal abatement is important relative to tax generation, the regulator cannot use the policy of offering the firm a set of linear tax schemes from which to choose. By contrast, this policy is optimal in the Laffont-Tirole model under certain not very restrictive assumptions. We proceed to establish a simple rule for when to shut-down inefficient types. In an example with specific functional forms, we derive the optimal tax function both analytically and graphically. We show the effect on the optimal tax system of a change in a technological parameter.  相似文献

This paper presents a model of money and search where bargaining determines prices and the quality of goods is private information. It studies how a lemons problem affects the purchasing power of money. There are multiple, Pareto-ranked equilibria. The superior equilibrium, where no lemons are produced, exists even if information about quality is relatively scarce. In other equilibria, there is price dispersion, and uninformed buyers pay higher prices than informed buyers for all goods. Taxing money balances (a proxy for inflation) makes buyers less selective, thus reducing the average quality of supply and the premium paid for known quality.  相似文献

The paper examines the optimal innovation of securities by an issuer who is endowed with several risky assets and private information on one of the assets. Assuming that the degree of asymmetric information between the issuer and the outside investor is large, we show that the issuer restricts the number of securities that he creates. We also show that the payoff of the security created by the issuer is not closely correlated, and is sometimes completely uncorrelated, with the payoff of the asset that is subject to the asymmetric information, depending on the hedging needs and the accuracy of information.

This paper analyzes the problem faced by a border protection agency if endogenous exporter abatement activities affect invasive species risk, allowing for unobservable differences in abatement cost. We show how the optimal inspection/penalty regime differs from the symmetric information case. Departing from previous literature, we allow for technical assistance, a policy instrument specifically permitted and commonly employed under Article 9 of the World Trade Organization Sanitary and Phytosanitary Agreement. We find the information asymmetry can make it optimal for the importing country to provide technical assistance grants for exporter risk abatement, even if it would otherwise be inefficient. Further, we show that fungibility of technical assistance with inputs in other sectors of the exporting economy affects the qualitative nature of optimal policy. If technical assistance has no outside value in the exporter’s country, optimal policy is characterized by a menu of contracts balancing higher tariffs with lower penalties for being caught with an invasive. If technical assistance can be used in other sectors of the exporter’s economy, it can introduce countervailing incentives making a uniform tariff/penalty combination optimal.  相似文献

信息不对称资本市场的实验研究   总被引:17,自引:0,他引:17  
我们采用经济学实验研究方法构建了信息不对称的实验室资本市场,研究信息是否可以通过市场迅速传递。实验结果表明,在信息不对称的情况下,资本市场是非有效的;市场对信息的传递和价格反应是有条件的而且也是需要时间的;资本市场中的投资者并非完全理性,而是具有认知和行为偏差的普通人,存在过度自信和过度交易的情况;信息不对称还可能引起市场操纵行为,从而导致价格泡沫的形成。  相似文献

We consider the regulation of a duopoly under incomplete information. When firms act noncooperatively, the regulator uses yardstick mechanisms to bridge his informational gap at no cost. However, this provides the firms with an incentive to collude.
We interpret the correlation as a measure of the congruence/divergence between individual and coalitional incentives. Under positive correlation, these incentives are aligned: the threat of collusion forces the regulator to distort the allocation. Under negative correlation, these incentives are opposed: the regulator can, sometimes, exploit this conflict of interest inside the coalition to eradicate the stakes of collusion at no cost.  相似文献

We study an economy with free firm entry and unemployment due to firm-worker bargaining over each firm's surplus, and where firms cause pollution that can be reduced by initial investments. An uncompensated increase in the pollution tax reduces pollution but increases unemployment, implying a tradeoff between the two. When tax revenues are used to subsidize either firms' hiring or investments, employment may also increase, creating a double dividend from the pollution tax. A pollution tax increase used to subsidize current employment is always less effective than a hiring subsidy, and is totally ineffective when subsidies equal pollution tax revenues for each individual firm. We show that the (hypothetical) pollution tax implementing the first-best solution exceeds the Pigouvian tax. The second-best tax exceeds this first-best tax when we have a double dividend, and is below it when we do not.  相似文献

This paper examines the implications of various contracting alternatives between exporting and importing firms on the volume of international transactions. the contracts that we study are determined in a bargaining situation under exchange-rate uncertainty. First we look at contracts which entail an ex ante commitment on price and quantity of exports without the possibility of renegotiation ex post. Second, spot contracts, i.e., the price and the quantity of exports are negotiated after the exchange the rate is known. A third type of contracts consists of ex ante commitment and ex post renegotiation.  相似文献

Alternating-Offer Bargaining with Two-Sided Incomplete Information   总被引:1,自引:0,他引:1  
I study alternating-offer bargaining games with two-sided incomplete information about the players' discount rates. For both perfect Bayesian equilibrium and a rationalizability-style notion, I characterize the set of expected payoffs which may arise in the game. I also construct bounds on agreements that may be made. The set of expected payoffs is easy to compute and incorporate into applied models. My main result is a full characterization of the set of perfect Bayesian equilibrium payoffs for games in which the distribution over the players' discount rates is of wide support, yet is in a weak sense close to a point mass distribution. I prove a lopsided convergence result: each player cannot gain from a slight chance that she is a strong type, but the player can suffer greatly if there is a slight chance that she is a weak type.  相似文献

Repeated Bargaining with Persistent Private Information   总被引:1,自引:0,他引:1  
The paper analyses repeated contract negotiations involving the same buyer and seller where the contracts are linked because the buyer has persistent (but not full y permanent) private information. The size of the surplus being divided is specified as a two-state Markov chain with transitions that are synchronized with contract negotiation dates. Equilibrium involves information cycles triggered by the success or failure of aggressive demands made by the seller. Because there is persistence in the Markov chain generating the surplus, a successful demand induces the seller to make another aggressive demand in the next negotiation, since the buyer's acceptance reveals that the current surplus is large. Rejection of an aggressive demand, on the other hand, leads the seller to be pessimistic about the size of the surplus in the next contract, so the seller makes a "soft" offer that is sure to be accepted. Then, after several such offers have been accepted, the seller is optimistic enough to again make an aggressive demand, creating an information cycle. An interesting feature of this cycle is that the soft price is not constant, but declines as the cycle continues, so as to offset the buyer's option value of re-starting the cycle when the current state is bad. An explicit mapping is given for the relationship between the basic parameters and the equilibrium prices and quantities; in particular, there is a closed-form solution for the threshold belief that makes the seller indifferent between hard and soft offers.  相似文献
