Using a theoretical model of noisy expert advice, I show that language inflation can be a rational response to the vagueness of language. Experts will tend to overstate their positions to a like‐minded decision maker (DM) and this constitutes a Pareto improvement over sending a sincere message. When the message space is bounded, overstatement may interfere with the DM's ability to aggregate the experts' information, because communication is less precise when the same message is sent for many states of the world. Despite this, I show that experts are willing to send either the most extreme message to the DM, or a partially overstated message, because by doing so the expert can decrease the likelihood the DM makes a suboptimal decision due to his subjective interpretation of the advice. Because the expert inflates his message toward the policy he believes the DM would be better off choosing, rather than sincerely revealing his information, I refer to this behavior as a paternalistic bias. 相似文献

When can you trust an expert to provide honest advice? We develop and test a recommendation game where an expert helps a decision maker choose among two actions that benefit the expert and an outside option that does not. For instance, a salesperson recommends one of two products to a customer who may instead purchase nothing. Subject behavior in a laboratory experiment is largely consistent with predictions from the cheap talk literature. For sufficient symmetry in payoffs, recommendations are persuasive in that they raise the chance that the decision maker takes one of the actions rather than the outside option. If the expert is known to have a payoff bias toward an action, such as a salesperson receiving a higher commission on one product, the decision maker partially discounts a recommendation for it and is more likely to take the outside option. If the bias is uncertain, then biased experts lie even more, whereas unbiased experts follow a political correctness strategy of pushing the opposite action so as to be more persuasive. Even when the expert is known to be unbiased, if the decision maker already favors an action the expert panders toward it, and the decision maker partially discounts the recommendation. The comparative static predictions hold with any degree of lying aversion up to pure cheap talk, and most subjects exhibit some limited lying aversion. The results highlight that the transparency of expert incentives can improve communication, but need not ensure unbiased advice. 相似文献

We extend the Shapley-Scarf (1974) model - where a finite number of indivisible objects is to be allocated among a finite number of individuals - to the case where the primary endowment set of an individual may contain none, one, or several objects and where property rights may be transferred (objects inherited) as the allocation process unfolds, under the retained assumption that an individual consumes at most one object. In this environment we analyze the core of the economy and characterize the set of strategy-proof and Pareto efficient mechanisms. As an alternative approach, we consider property rights implicitly defined by a strategy-proof and Pareto efficient mechanism and show a core property for the mechanism-induced endowment rule.Received: 19 February 2004, Accepted: 14 April 2005, JEL Classification:

A model is analyzed in which agents exert effort to create innovations within an organization. When payments are infeasible, the decision on the implementation of a proposal is shown to be made by simple monotonic decision rules. Organizational structure is then determined by a collection of decision rules. A trade-off arises between the use of information and the incentives created by a rule. If the former dominates it will currently be optimal to install a hierarchy. Otherwise decentralization by granting autonomy to innovators may be better. Requiring unanimous decision-making is optimal if a strong filtering of proposals is necessary.Received: June 2001, Accepted: May 2002, JEL Classification:

To say that a democratic system of government ought to be responsive to the opinions of the citizens sounds like a truism which could hardly be expected to generate much controversy. Yet, the notion of responsiveness turns out to be open to several nonequivalent interpretations: Condorcet-consistency, monotonicity, invulnerability to the no-show paradox, to name the most important ones. Several results have been achieved to establish incompatibilities between these properties. We shall review some of these and discuss some similar notions and their relationships with those just mentioned.Received: 5 August 2003, Accepted: 19 March 2004, JEL Classification:

The survey is focused on the typical problems in information transmission from experts to non-experts. Attention is paid to the factors that can affect information disclosure in models that apply a game-theoretic approach to the use of professional advice. In the economic literature expertise is mainly analyzed as a special case of asymmetric information between expert and non-expert. The contributions are reviewed according to a double criterion, that takes into account both the preferences of the experts and the properties of communication. On one side, either the non-expert plays the role of a decision-maker, who chooses an action that is payoff-relevant for the expert, or the preferences of the expert directly depend on some measure of his reputation as a high-ability forecaster. On the other side, communication can range from pure cheap talk to completely verifiable messages. 相似文献

This paper develops a political-economy model to investigate to what extent a rise of environmentalism can successfully encourage higher pollution taxes and reduce pollution. The model focuses on special-interest group politics, intra-industry trade and a transnational environmental externality. The main finding is that a rise of environmentalism is not sufficient to protect the environment when pollution is relatively immobile and environmentalists are concerned with pollution in other countries than their own.Received: January 2004, Accepted: November 2004, JEL Classification:

I study a model where personal income is a function of two different groups of individual characteristics, called “talent”
and “effort” respectively. The distinction between these two groups is that society has taken the prior decision that the
influence of traits from the first group needs to be moderated by any fair redistribution mechanism while differences in income
due to traits from the second group must be preserved. I present two solutions that satisfy several intuitive properties of
fairness and I use these properties to characterize both of them.

This paper examines the economic and political conditions that influence peoples attitudes regarding a municipality break-up. The theoretical model predicts intra-municipal differences in tax bases, political preferences, and population size to affect the expected gain from secession. The predictions of the model are tested using data on local referenda about municipality partitioning in Sweden. The data support one of the three effects; voters in municipality parts that are wealthy compared to other parts of the same municipality are more positive to secession.Received: April 2003, Accepted: September 2003, JEL Classification Numbers:

In a simple model of one public good producible from one input, we show that unit-by-unit cost-sharing rules have two properties. First, a unit-by-unit cost-sharing rulealways chooses a core allocation. Second, every allocation in the core will be chosen by at least one unit-by-unit cost-shring rule. We argue that costs should be shared on a unit-by-unit basis. We propose a simple mechanism to implement the family of unit-by-unit
rules.

The efficiency of decomposition vs direct solution with implications for the question of decentralized or centralized planning 总被引:1,自引:0,他引:1
K. P. Wong 《Economics of Planning》1973,13(3):199-209
Conclusion The investigation provides overwhelming evidence that decomposition tends to become increasingly more efficient than direct solution as the number of subproblems becomes greater.Further investigation would be required to obtain a comparable picture of the behaviour of decomposition with respect to an increasing number of variables in the master problem as their range of variation in the present study is rather restricted.It is gratefully acknowledged: that in implementing the decompositional procedure on the computer I have benefitted from Mr. A. C. McKay's advice on matters relating to the computer programmes; also that I enjoyed the pleasant and friendly co-operation of the staff of the computer Centre, University of Birmingham, without which the difficulties involved in carrying out the present task would have been compounded manifold; that Dr. C.-L. Sandblom carefully studied this paper and suggested a number of valuable improvements. Finally, I should like to thank Professor Kronsjö for the encouragement that he has given to me in executing this project and to the research council which made this investigation possible. 相似文献

It is argued in this paper that the solution concept of an evolutionary stable strategy (ESS) is an adequate analysis tool for contest theory. Moreover, it is shown that in a contest ESS always differs from Nash equilibrium, the hitherto dominant solution concept in contest theory. Finally, an interpretation of finite population ESS contest behavior in terms of Nash behavior is supplied.Received: 10 February 2002, Accepted: 8 July 2002, JEL Classification:

This paper characterizes the optimal insurance contract in an environment where an informed agent can misrepresent the state of the world to a principal who cannot credibly commit to an auditing strategy. Because the principal cannot commit, the optimal strategy of the agent is not to tell the truth all the time. Assuming that there are T > 1 possible losses, and that the agent cannot fake an accident (he is constrained only to misreport the size of the loss when a loss occurs), the optimal contract is such that higher losses are over-compensated while lower losses are on average under-compensated. The amount by which higher losses are over-compensated decreases as the loss increases. The optimal contract may then be represented as a simple combination of a deductible, a lump-sum payment and a coinsurance provision.Received: 29 January 1999, Accepted: 26 June 2001, JEL Classification:

It is shown that the Pazner-Schmeidler social ordering appears as a very natural solution to the problem of defining social preferences over distributions of divisible goods. The paper analyses various ways of deriving this social ordering from minimally egalitarian conditions and informational parsimony requirements.Received: 10 October 2003, Accepted: 4 April 2005, JEL Classification:

Hurwicz (1979) and Otani and Sicilian (1982, 1990) characterized the Nash equilibrium allocations of the Walrasian demand manipulation game in successively more general exchange environments. In this paper, I extend the analysis to production economies with short-selling. First, I generalize Hurwicz’s and Otani and Sicilian’s theorem that any allocation at which each agent’s consumption bundle lies above her true offer curve can be supported in Nash equilibrium. I then show that for finite economies of any size the set of such allocations is often topologically large.Received: 17 January 2003, Accepted: 4 April 2005, JEL Classification:

On how size and composition of customer bases affect equilibrium in a duopoly with switching costs 总被引:1,自引:0,他引:1
Switching costs may facilitate monopoly pricing in a market with price competition between two suppliers of a homogenous good, provided the switching cost is above some critical level. It is also well known that asymmetric size of customer bases makes monopoly pricing more difficult. Adding consumer heterogeneity to the model we demonstrate that also composition of each firms customer base affects pricing, and this composition may aggravate or ease the incentives to break out of the monopoly pricing equilibrium.Received: 16 August 2001, Accepted: 27 September 2004, JEL Classification:

In an internal capital market, individual departments may compete for a share of the firm’s budget by engaging in wasteful influence activities. We show that firms with more levels of hierarchy may experience lower influence costs than less hierarchical firms, even though the former provide more opportunities for exerting influence. The unique influence-cost minimizing hierarchy is strongly asymmetric. With a linear production technology this is also the optimal hierarchy. If individual departments have different productivities, however, and the production technology exhibits decreasing returns to scale, a symmetric hierarchy that does not minimize influence costs may be optimal.Received: July 2004, Accepted: October 2004, JEL Classification:

This paper contributes to the existing money demand literature by developing and estimating a shopping-time model in an open
economy framework. Based on this microfoundations-of-money model, United Kingdom quarterly data for the period 1973:2–1997:2
are analyzed in the empirical study. After accounting for nonstationarity in the time series processes, I find three long-run
relationships among the relevant variables. Estimation of the error-correction representation implied by the model shows that
the foreign exchange rates and the imports consumption, in addition to the domestic variables, have significant effects on
British demand for real money.

With data gained from a controlled field experiment in Switzerland this paper analyses the effects of moral suasion on the timely paying and the timely filling out of the tax form 2001. Comparisons of different tax filing years and multiple regression estimations have been done using these two factors as dependent variables to check if there is a significant difference between the control group and the treatment group. In February 2002 the treatment group received a letter signed by the communes fiscal commissioner containing normative appeals. Results indicate that moral suasion has hardly any effect on taxpayers compliance behaviour. The strongest effect can be observed for the variable tax payments.Received: February 2003, Accepted: June 2004 JEL Classification:
