论纳税人的权利与义务

在税收关系中,国家作为权利主体有依法征税的权利,纳税人作为义务主体有依法纳税的义务。但国家作为税收主体对其征税权利应伴有相应义务,纳税人的纳税义务应伴有相应权利这一重大问题的在我国理论界和实际工作中都没有予以足够的重视。在传统税收理论中,被视为区别税与非税标志的税收“三性”,即强制性、无偿性和固定性是我国传统税收观念的理论基础。我们认为,国家对税收中单方面强调强制性、无偿性还远远不够。应以本文的“     

Occupational behavior and attitudes among new RNs

A statewide survey of 2,315 (97%) RNs taking the Massachusetts licensure exam identified major reasons for selecting a nursing career, degree program, and a job. A high degree of consistency in their occupational attitudes and behaviors offers a blueprint for recruitment and insight into retention issues.     

Coalitional strategy-proofness and fairness

This paper considers the problem of assigning a finite number of indivisible objects, like jobs, houses, positions, etc., to the same number of individuals. There is also a divisible good (money) and the individuals consume money and one object each. The class of fair allocation rules that are strategy-proof in the strong sense that no coalition of individuals can improve the allocation for all of its members, by misrepresenting their preferences, is characterized. It turns out that given a regularity condition, the outcome of a fair and coalitionally strategy-proof allocation rule must maximize the use of money subject to upper quantity bounds determined by the allocation rule. If available money is nonnegative, objects may be jobs and the distribution of money a wage structure. If available money is negative, the formal model may reflect a multi-object auction. In both cases fairness means equilibrium, i.e., that each individual receives a most demanded object.

Bargaining under incomplete information, fairness, and the hold-up problem

In the hold-up problem incomplete contracts cause the proceeds of relationship-specific investments to be allocated by bargaining. This paper investigates the corresponding investment incentives if individuals have heterogeneous fairness preferences. Individual preferences are taken to be private information. Investments can then signal preferences and thereby influence beliefs and bargaining behavior. In consequence, individuals might choose high investments in order not to signal information that is unfavorable in the ensuing bargaining.     

Institutional framing and perceptions of fairness

This paper's goal is to construct a positive theory of economic fairness. Using the theoretical schema developed by Hurwicz and others, the paper makes precise the notions of an “institution,” “fairness fraiming,” and “institutional framing.” Four fairness propositions yield an important corollary: the economic environment, the operative institution and history give meaning to the often used FORMAL PRINCIPLE OF DISTRIBUTIVE JUSTICE (“equals should be treated equally, and unequals unequellay, in proportion to relevant similarities and differences”). We support these four propositions and corollary by an analysis of laboratory, survey, and anecdotal evidence. Finally we describe a number of areas for future research. The authors would like to thank Allen Buchanan, James Buchanan, Joel Feinberg, Elizabeth Hoffman, David Schmitz, Linda Schnabel Stizer, Vernon Smith, Richard Wagner, the participants in the Aspen Institute's Conference on “Local Justice and Fair Allocation”, the members of the Industrial Organization Workshop of the Department of Economics at the University of Arizona, and panel participants at the Public Choice Society Meeting for their help and comments at various stages of this paper's preparation.

Compensation payments for habitat heterogeneity: Existence, efficiency, and fairness considerations

Compensation payments for voluntary conservation measures have become an important tool for biodiversity conservation worldwide. Each year substantial financial resources are spent on such measures, particularly in the context of agri-environmental schemes. In Europe, a debate has started on whether this money is spent effectively. In response to this debate it has been suggested that a portfolio of measures leading to habitat heterogeneity be implemented. Although payments for heterogeneous conservation measures have been analysed in the literature, it has never been questioned that payments can be designed in a way that encourages enough land users to carry out each conservation measure within a portfolio of measures. The purpose of this paper is to demonstrate that such payments do not always exist. Moreover, in cases where payments for habitat heterogeneity exist the payment scheme may require overcompensation of the land users, posing a limit to both efficiency and fairness considerations.     

Investment behavior and the biased perception of limited loss deduction in income taxation

We use a laboratory experiment to study the extent to which investors’ choices are affected by limited loss deduction in income taxation. We first compare investment behavior in the no tax baseline to a tax control setting, in which the income from investments is taxed. We find that investors significantly reduce their risk-taking as predicted by theory. Next we compare the baseline investment choices to choices under three different types of income taxation. We observe that risk-taking is significantly increased with partial and with capped loss deduction, but is unaffected by a tax system that allows no loss deduction. Since in all these treatments the after tax outcomes of the prospects were identical, we conjecture that investors have a positively biased perception of partial and capped loss deduction that promotes their willingness to take risks.     

Multilateral tariff cooperation under fairness and reciprocity

Abstract This paper explores the impact of fairness and reciprocity on multilateral tariff cooperation. Reciprocal countries reward kind behaviour (positive reciprocity), but retaliate against countries behaving unkindly (negative reciprocity). We demonstrate that reciprocal countries that are moderately demanding from their trading partners regarding their commercial policy can support a greater degree of cooperation than self‐interested ones. However, when only very liberal import policies are considered fair, then reciprocity could have a detrimental effect on multilateral tariff cooperation.Thus, our model provides a novel perspective on the role of expectations in trade negotiations.     

On the fairness of random procedures

We consider procedures that use randomness to make a decision that involves several individuals. We asked subjects to compare the fairness of six pairs of seemingly equivalent procedures. We propose a classification of subjects into two categories: those who are “emotional” in the sense that they exhibit a systematic ranking of procedures on the basis of intuitive notions of fairness, and those who are “consequentialists” in the sense that they systematically view each pair of procedures as being equally fair. According to this classification, about 30% of the subjects are emotional while 31% are consequentialists.     

Dissertation abstract: Experiments on fairness and reputation

The three dissertation essays investigate different aspects of reputation in games where fairness is an important consideration. The first essay studies the effects of reputation on indirect reciprocity in different dictator games. The first experiment places dictators in two environments where they can either give money to the paired player or take money away from them: in one treatment the paired player is a stranger and in the other treatment the dictator has information on the paired player’s reputation. Contrary to anecdotal evidence, the statistical tests show that the dictators’ behavior towards a stranger is not statistically significantly different from their behavior towards an individual with an established reputation. The findings arise because a high proportion of dictators acted purely in their own self interest in both treatments. The data also provides evidence that dictators are more generous when they know that their choices (but not their identities) will be revealed in the future. In the second experiment the dictators’ choices were restricted to only generous actions. In such environment the dictators sent more money on average to recipients with a reputation for being generous than to recipients without a reputation. The second essay explores the ways in which information about others’ actions affects one’s own behavior in a dictator game. The experimental design discriminates behaviorally between three possible effects of recipient’s within-game reputation on the dictator’s decision: reputation causing indirect reciprocity, social influence, and identification. The separation of motives helps to identify the mechanisms of social transmission of impulses towards selfish or generous behavior. The data analysis reveals that the reputation effects have a stronger impact on dictators’ actions than social influence and identification. In the third essay¹ we examine the reputation effects in a labor market setting by analyzing the influence of negative technological shocks on long run relationships between firms and workers. The positive correlation between wage and effort in static conditions has been demonstrated in many experimental studies and has been one of the prominent explanations for the existence of wage rigidity. We subject these findings to further tests in a non-stationary environment that better corresponds to outside-the-lab market conditions. We observe the positive correlation of wages and effort but do not find support for downward wage rigidity in our data. Once the shocks occur, firms lower the wages and relationships often break down. The workers who accept a lower wage respond with exerting a lower effort.

Existence and fairness of value allocation without convex preferences

Shafer (Econometrica, 48 (1980), 467–476) proved that in a finite exchange economy value allocations exist, provided that each agent has convex, complete, transitive, compact and monotone preferences. However, if preferences are not convex, then value allocations may not exist. To remedy this difficulty we enlarge the set of value allocations by introducing the concept of approximate value allocations, and show that in a finite exchange economy approximate value allocations exist, even if preferences are not convex, or compact, or monotone. This value existence result can be used to provide a very general value existence theorem for a sequence of finite economies. Further, we show that value allocations may discriminate in favor of or against a coalition of agents.     

Consumer perception,information provision,and regulation of insurance markets

Available evidence shows that consumers overinsure against modest risks. For instance, a majority of consumers tend to choose too low a level of deductible for homeowners insurance and automobile insurance, and purchase excessive warranties for electronics and other durable products such as automobiles and furniture. The analysis demonstrates that overinsurance decreases consumer welfare and increases insurers’ profits. This tendency of overinsurance stems from lack of information about the probability and magnitude of loss, and it calls for policies that require insurers or third-party organizations to provide more, albeit not perfect, information and data for consumers before they make insurance-purchase decisions. The implications of the analysis for other financial products such as stocks and deposits are discussed.     

Yield management and perceptions of fairness in the hotel business

For the last two decades “yield management” (also called “revenue management”) has been increasingly employed in the hospitality sector in order to improve the yield from hotel structures. What’s more, the focus is progressively more centred on the customer instead of the room inventory. However, up to now, little research has investigated the effects of these practices on the relationships between hotels and their clients. This paper firstly examines the nature and the various aspects of customer perceptions regarding yield management practices, focusing especially on perceptions of fairness. Secondly, the paper analyses the variety of actions that hotel companies may design and implement in order to properly anticipate, face and manage customer conflicts resulting from perceived unfairness due to the use of the revenue management levers. Finally, these managerial techniques adopted by the hotel companies are considered in the framework of a business ethics approach.

International support of climate change policies in developing countries: Strategic, moral and fairness aspects

International transfers in climate policy channeled from the industrialized to the developing world either support the mitigation of climate change or the adaptation to global warming. From a purely allocative point of view, transfers supporting mitigation tend to be Pareto-improving whereas this is not very likely in the case of adaptation support. We illustrate this by regarding transfer schemes currently applied under the UN Framework Convention on Climate Change (UNFCCC) and the Kyoto framework.However, if we enrich the analysis by integrating distributional aspects, we find that international adaptation funding may help both the developing and developed world. Interestingly this is not due to altruistic incentives, but due to follow-up effects on international negotiations on climate change mitigation. We argue that the lack of fairness perceived by developing countries in the international climate policy arena can be reduced by the support of adaptation in these countries. As we show - taking into account different fairness concepts - this might raise the prospects of success in international negotiations on climate change. Yet, we find that the influence of transfers may induce different fairness effects on climate change mitigation negotiations to run counter.We discuss whether current transfer schemes under the UNFCCC and the Kyoto framework adequately serve the distributive and allocative objectives pursued in international climate policy.     

Risk attitudes, randomization to treatment, and self-selection into experiments

Randomization to treatment is fundamental to statistical control in the design of experiments. However randomization implies some uncertainty about treatment condition, and individuals differ in their preferences towards taking on risk. Since human subjects often volunteer for experiments or are allowed to drop out of the experiment at any time if they want to, it is possible that the sample observed in an experiment might be biased because of the risk of randomization. On the other hand, the widespread use of a guaranteed show-up fee that is non-stochastic may generate sample selection biases of the opposite direction, encouraging more risk averse samples into experiments. We directly test these hypotheses that risk attitudes play a role in sample selection. Our results suggest that randomization bias does affect the overall level of risk aversion in the sample we observe, but that it does not affect the demographic mix of risk attitudes in the sample. We show that the common use of non-stochastic show-up fees can generate samples that are more risk averse than would otherwise have been observed.     

Secrecy and fairness in plea bargaining with multiple defendants

I consider a model of plea bargaining with multiple codefendants. I mainly compare the equilibrium outcomes under joint negotiations whereby both defendants can observe both plea offers and under separate (secret) negotiations whereby they can observe only their own respective offer. Contrary to the widespread perceptions, the prosecutor is made worse off under secret negotiations or at best as well off as under joint negotiations. I also discuss the implication of equilibrium offers on fairness.      

Individual sense of fairness: an experimental study

Many prior studies have identified that subjects in experiments demonstrate preferences for fair allocations. We present an experimental study designed to test whether a similar concern for fairness manifests itself when the decision maker is choosing among differing probabilistic allocation mechanisms that will all generate an ex post unfair allocation by assigning an indivisible prize to one individual. This investigation is inspired by Karni and Safra (Econometrica, 70, 263–284, 2002 ) in which a structure for preferences for fairness in such an environment was developed. Here we use this model to design experiments that allow us to test for the presence of concern for fairness in individual choice behavior and examine some factors that may affect the intensity of the concern for fairness.
