A Revelation Mechanism for Soft Information under Moral Hazard

This paper constructs a revelation mechanism to address a problem of moral hazard under soft information. The agent alone observes the stochastic outcome of her action, which she reports to the principal. Therefore the principal also faces a problem of ex post adverse selection. Economically relevant restrictions induce constraints on the principal's choice of mechanism and the Revelation Principle fails to apply. Specifically, a direct mechanism induces some pooling, which does not replicate the allocation obtained using a larger message space. Pooling also weakens the ex ante incentives. The Revelation Principle is extended to obtain type separation. A better audit relaxes frictions.     

A Humean theory of choice of which rationality may be one consequence

For the reader who considers economic theory of choice as a special case of a more general theory of action, Hume's discussion of the determinants of action in the Treatise of Human Nature (1739?–?40), in the Enquiry on Human Understanding (1748) and in the Dissertation on Passions (1757) deserves attention. However, according to some modern commentators, Hume does not seem to have given any evidence that would favour what nowadays we would consider as the kind of rationality involved in modern theories of rational choice. On the contrary, this paper arrives at the conclusion that consistency between preferences and choice, like the usual properties of completeness and transitivity, may be considered as outcomes of a mental process, described by means of a decision algorithm that aims to represent Hume's theory of choice.     

Private investment with social benefits under uncertainty: The dark side of public financing

We develop a game‐theoretic model of private–public contribution to a long‐term project with sequential actions and moral hazard. A private agent is one who is in charge of both the financial contribution and the management effort, these two actions entailing private costs and uncertain ex‐post private and social benefits. A public agent is one who decides the amount of public funding to this quasi‐public good, knowing that the size and the probability of attaining a surplus ex post depend on the private agent's effort. We consider four public‐funding scenarios: benefit‐sharing versus cost‐sharing crossed with ex‐ante versus ex‐interim government intervention. We test our theoretical predictions by means of an experiment that confirms the main result of the model: Cost‐sharing public intervention is more effective than benefit‐sharing in boosting private financial contribution to the project. Furthermore, when public intervention comes after private contribution ( ex‐interim government intervention), both public‐funding scenarios have a negative impact on the private management effort. In our model, the latter result is explained by the private agent's high degree of risk aversion. These results have policy implications for strategic investments with long‐term social consequences. In deciding the optimal timing and method of the contribution, governments should also consider the indirect effects on agents’ long‐term management efforts.     

Monopolistic Screening with Boundedly Rational Consumers*

In this paper, I revisit the monopolistic screening problem with two types assuming that consumers are boundedly rational. Bounded rationality implies that the revelation principle does not apply and the choice of the selling mechanism entails a loss of generality. I show that if the monopolist restricts attention to the mechanisms that offer menus of two choices, the profits are lower than in the case of fully rational consumers by the term of order ln λ/λ, where λ is the degree of rationality of the consumers. The monopolist, however, can approximate the profits earned when consumers are fully rational by using a more elaborate message game.     

COPYRIGHT AND BRANDS IN THE DIGITAL AGE: INTERNALIZING THE EXTERNALITIES OF MEANING

The adoption of binary code as the universal standard for globalized communications generates highly positive externalities of the kind often referred to as “network effects.” But what about meaning? What are the externalities associated with the formatting and circulation of meaning, and are they all positive? Within the digital paradigm, is it really possible to separate the notion of expression—covered by copyright—from the meanings conveyed? Isn't meaning closely related to the concept of brand? And on that assumption, how do copyright and trademark institutions work together to stimulate and promote the generation of meaningful information? To answer these questions, we will look at how the meaningful forms of expression—the “works”—that have historically been covered by copyright generate specific types of externality, both positive and negative, giving rise to both incentive and censorship mechanisms. We will then show how the institutions of copyright and author's rights that allow the appropriation of a meaning‐dependent good also confer a brand on it by identifying its sources. This leads to cross‐externalities between works of expression and publishing brands, with the result that copyright and trademark institutions cannot be completely separated from each other.

Lexicographic choice under variable capacity constraints

In several matching markets, to achieve diversity, agents' priorities are allowed to vary across an institution's available seats, and the institution is let to choose agents in a lexicographic fashion based on a predetermined ordering of the seats, called a (capacity-constrained) lexicographic choice rule. We provide a characterization of lexicographic choice rules and a characterization of deferred acceptance mechanisms that operate based on a lexicographic choice structure under variable capacity constraints. We discuss some implications for the Boston school choice system and show that our analysis can be helpful in applications to select among plausible choice rules.     

Happiness, freedom and control

How do people value freedom of choice? Drawing on economics and psychology the paper provides an hypothesis and empirical evidence on how individuals may value freedom of choice and derive utility from it. It is argued that the degree of perceived control that individuals have over choice – a construct known as the locus of control in psychology – regulates how we value freedom of choice. People who believe that the outcome of their actions depends on internal factors such as effort and skills (the ‘internals’) have a greater appreciation of freedom of choice than people who believe that the outcome of their actions depends on external factors such as fate or destiny (the ‘externals’). We find some evidence in support of this hypothesis using a combination of all rounds of the World and European Values Surveys. A variable that measures freedom of choice and the locus of control is found to predict life satisfaction better than any other known factor such as health, employment, income, marriage or religion, across countries and within countries. We show that this variable is not a proxy of happiness and measures well both freedom of choice and the locus of control. ‘Internals’ are found to appreciate freedom of choice more than ‘externals’ and to be happier. These findings have important implications for individual utility, social welfare and public policies.     

Uncertainty and the Voluntary Provision of a Pure Public Good in a Two‐Moment Decision Model

In this paper, we explore the potential benefits of uncertainty that may arise in a two‐moment model of the voluntary provision of a pure public good. We find that an increase in a given contributor i’s risk associated with the aggregate contribution level of the other contributors (i.e., an increase in social uncertainty) induces that contributor to increase his own contribution level if and only if the uncertainty's incremental effect on the expected value of his net marginal utility is negative. Contributor i’s welfare likewise increases when a closely related condition is met, namely that the uncertainty's marginal effect on his expected marginal utility value of the public good exceeds its countervailing effect on the numeraire. Further, the corresponding aggregate contribution to the public good increases in the presence of free‐riding if and only if the incremental effect of contributor i’s contribution on the aggregate expected value of all other contributors’ net marginal utilities is small‐enough positive. We derive similar conditions for the case of private uncertainty, where the increase in contributor i’s risk is associated with his own marginal valuation of the public good. A simple example illustrates these conceptual results. Numerical analysis demonstrates that an increase in private uncertainty can have a nonmonotonic impact on contributor i’s welfare.     

The growth–distribution nexus in a mixed regime of education with a status motive: On the macroeconomics of the welfare state

We develop a growth model with human capital accumulation to study the effects of status-driven motivation on individuals' choice between public or private education. This choice interacts with and exacerbates the effects of status, with implications for growth and distribution. More motivated individuals work harder and choose private education. In a majority voting/median voter setup, individuals choose a public education size for which there is no trade-off between long-term growth and inequality. We also highlight the conflict of interest between individuals with respect to the size of the public education sector and the tax rate that supports it. We thus highlight important interactions between the macroeconomy, social attitudes and educational institutions and derive results of interest in a variety contexts. We end by drawing policy conclusions among which, the idea that in democracies, higher growth and lower inequality are mutually compatible when the government promotes public education.     

Buchanan’s constitutional political economy: exchange vs. choice in economics and in politics

This article discusses the methodological foundations of Buchanan’s constitutional political economy. We argue that Buchanan is a constitutional economist because he is an economist or a political economist. In other words, Buchanan is a constitutional economist—he insists on the necessity of focusing on constitutions and to analyze the “rules of the social game”—because he defines economics as a science of exchange. Buchanan’s definition of economics is not only specific, it is also opposed to the definition of economics that other economists retain and, above all, opposed to the definition of economics that many public choice theorists use. The latter have, in effect, adopted the Robbins 1932 definition of economics as a science of choice that Buchanan criticizes and rejects. Buchanan’s constitutional economics can be a branch of public choice only under certain conditions.

Public Enterprise Privatization: A General Equilibrium Analysis

This paper develops a general equilibrium model to examine the short‐run and long‐run optimal privatization policies. By assuming that all firms are public firms initially, the paper focuses on how the degree of product differentiation γ and the average efficiency of the industry influence the determination of the optimal privatization policy. The paper shows that privatization decreases the more efficient firms' outputs while increases the less efficient firms' outputs in the short run, and reduces all firms' outputs in the long run. The paper also shows that the larger is γ and the smaller is the number of firms, the more privatized will be the public firm in the short run. Moreover, as γ or the entry barrier f_E is sufficiently small, full privatization is the best policy in the long run. On the contrary, as γ and f_E are large enough, partial privatization is optimal.     

Public decisions: Solidarity and the status quo

A public decision model specifies a set of alternatives, a variable population, and a common set of admissible preferences. We study the implications of the principle of solidarity, for social choice functions in all such models. The principle says that when the environment changes, all agents not responsible for the change should either all weakly win, or all weakly lose. Under weak additional requirements, but regardless the domain of preferences, each of two formulations of this principle, population-monotonicity and replacement-domination, imply coalition-strategy-proofness; that the choice only depends on the set of preferences that are present in the society, but not on the number, nor on the labels of agents having particular preferences; and that there exists an alternative always weakly Pareto-dominated by the alternative selected by the rule. Replacement-domination is generally at least as strong as population-monotonicity.     

Long‐term care policy with lazy rotten kids

This paper studies the determination of informal long‐term care (LTC) provided by children in a scenario which is somewhere in between perfect altruism and selfish exchanges. Parents are altruistic but children are purely selfish, and neither side can make credible commitments. The model is based on Becker's “rotten kid” specification except that it explicitly accounts for the sequence of decisions. In Becker's world, with a single good efficiency is achieved. We show that when family aid is introduced the outcome is likely to be inefficient. Still, the rotten kid mechanism is at work and ensures that a positive level of LTC is provided as long as the bequest motive is operative. We identify the inefficiencies by comparing the laissez‐faire (subgame perfect) equilibrium to the first‐best allocation. We first assume that families are identical ex ante and then consider the case where dynasties differ in wealth. We study how the provision of LTC can be improved by public policies. Interestingly, crowding out of private aid by public LTC is not a problem in this setting. With an operative bequest motive, public LTC will have no impact on private aid. More amazingly still, when the bequest motive is (initially) not operative, public insurance may even enhance the provision of informal aid.     

Public Information Quality with Monopolistic Sellers

We show that in markets with asymmetric information, even if there is full agreement on the choice of optimal information quality, entrusting the choice of (unverifiable) public information quality to traders who benefit from such information leads to inefficiencies. However, delegation of information quality choice to an independent agent who is precluded from sharing in trading profits results in efficient implementation. This result provides a game-theoretic rationale for current institutional arrangements where a private organization that is independent of market traders, the Financial Accounting Standards Board, determines the standards for public disclosures.Journal of Economic LiteratureClassification Numbers: D41, D42, D82.     

Completing Incomplete Revealed Preference Under Limited Attention

This paper discusses how to improve the identification of the preference of a decision‐maker (DM) with limited attention proposed by Masatlioglu, Nakajima and Ozbay (2012). in “Revealed Attention”. Their identification method relies on choice reversals so the obtained revealed preference is often incomplete. We propose three approaches to address this problem. The first one is accommodating a model‐free approach, which respects the DM's choice in making a welfare analysis, as long as it does not contradict the revealed preference of Masatlioglu et al. The second approach incorporates the DM's exogenously obtained attention/inattention information into the model of Masatlioglu et al. The third approach is to take framings that influence the DM's attention into effect for the identification.     

Thoreau's economic philosophy

Abstract

This paper provides an encompassing portrayal of Thoreau's economic thought. It is analyzed against the background of the history of economic thought and the economic thinking of his time. Thoreau's economic thought is an extensive examination of the ideas of classical political economy, and particularly of Jean-Baptiste Say, and it is a fundamental critique thereof. Thoreau recognizes that some aspects and foundations of the modern conception of the economy lead to an alienation of the human being from itself as well as to an alienation from nature. I demonstrate that this critique is a result of Thoreau's specific approach to the economy, which, based on his particular understanding of the human being and his philosophy of nature, seeks the meaning of the economy for human life and for nature. In this philosophical approach, which I characterize as an economic philosophy, Thoreau's deeper defiance of classical political economy and his original place within the history of economic thought are grounded. It leads Thoreau to an alternative conception of an economy of moderation, which is identified and described in detail. I conclude with considerations on the potential meaning of Thoreau's thought for current economic research.     

THE ECONOMICS OF ILLUSION*

When individuals choose not only goods, but also how to process information, there is a bias: people tend to process information so that they feel good about themselves. This bias is particularly important in voting behavior, where agents have almost no individual effect on public choice outcomes, and therefore almost no incentive for unbiased use of information. Two examples are given. In one example, an adaptation of the classic overdepletion problem, the public chooses not to counteract externalities by appropriate tax policy. In the second example public policy follows the choices of experts, contrary to the interest of the public.     

Biotechnology as a Technological Paradigm in the Global Knowledge Structure

The aim of this study is to analyse whether the receipt of public R&D funding determines firm's R&D strategy selection. This issue is crucial, as previous studies have shown that each R&D strategy is associated to a higher, or lower, innovation performance. We consider three R&D strategies – make, buy, make–buy – and three different sources of public funding – regional, state and other (such as EU). The model estimation is performed through a multinomial logit model with random effects with a sample of 457 large firms for the period 1992–2005, taken from the Spanish Survey of Business Strategies. The main finding is that the source of the funding influences whether firms select the make, buy or make–buy strategy. Additionally, because of the panel structure of the sample, we observe that the effect of public funding on the R&D strategy selection lasts longer for state and regional funds than for other funds.     

Human Fallibility, Complementarity, and Fiscal Decentralization

This paper examines economic growth properties under alternative fiscal organizations when a bureau's decisions are fallible. A country consists of J jurisdictions, which need a public service. In a centralized government, one authority decides on services in every jurisdiction. In a decentralized government, J authorities are in charge of each public service. An authority can have high ability or low ability, and an authority with high ability draws a good project with higher probability. We first show that the decentralized government provides the same average quality of public services, with lower variance, than does the centralized government. We then apply this result to an economic growth model where the value of the Solow residual is a constant elasticity of substitution (CES) function of public services. We show that there is a critical value of the degree of complementarity below which fiscal decentralization is more desirable than fiscal centralization for an expected economic growth, and the decentralized government has a lower variance of GDP growth.     

EXPERIENCE OF PRIVATIZATION IN EASTERN GERMANY*

ABSTRACT^**: The analysis of the experience of privatization in Eastern Germany shows that the boundaries between the private and public sectors will become increasingly blurred, with the public sector becoming more like the private sector. One may also expect that employment will fall and productivity greatly increase. The legislature's urge to regulate everything will ultimately subside but the public sector will continue to be of vital importance for the economy as a whole. A modernized public sector will be able to deploy its services to make an important contribution to economic growth and employment.
