Whales Get Beached, Don't They? An Essay on the Law and Economics of Copyrights in Music

L’auteur fonde son argument sur l’importance déterminante des conséquences économiques de la numérisation sur l’évolution des droits d’auteur afférant à la musique. La musique numérisée correspondant à un bien public, les prix de sa négociation tendent vers 0, et seules les contraintes légales telles que les droits d’auteur ou les ententes sur les prix, qui sont généralement proscrites par les lois sur la concurrence, peuvent sauver l’entrant intrépide ou l’opérateur mis sur le sable. Alors que les propriétaires de droits d’auteur maximisent leurs profits en prônant l’extension de leur champ d’application et en poursuivant leur application par les tribunaux, leur valeur sociale est mesurée en termes d’efficacité pour la promotion de l’innovation. L’industrie de la musique a projeté le champ d’application des droits d’auteur si grossièrement loin au–delà des limites de la raison par rapport à la musique numérisée que leur position légale sera attaquée inlassablement sur tous les fronts, que ce soit par une banalisation des infractions, ou par la résistance devant les tribunaux ou par des campagnes visant une réforme législative.

The law and economics of good faith in the civil law of contract

Good faith plays a central role in most legal systems, yet appears to be an intractable concept. This article proposes to analyse it economically as the absence of opportunism in circumstances which lend themselves to it. One of the objectives underlying the law of contract on an economic view is to curtail opportunism. In spelling out what this means, the paper proposes a three-step test: bad faith is present where a substantial informational or other asymmetry exists between the parties, which one of them turns into an undue advantage, considered against the gains both parties could normally expect to realise through the contract, and where loss to the disadvantaged party is so serious as to provoke recourse to expensive self-protection, which significantly raises transactions costs in the market. The three-step test is then used to analyse a set of recent decisions in international commercial transactions and three concepts derived from good faith: fraud, warranty for latent defects and lesion.

Methodology in Economics: the Logic of Appraisal

This Paper Intends to Develop a Coherent Methodological Framework Concerned with the Appraisal of Scientific Theories in Economics, and Which Is Based on a Postulated Aim of Science. We First Define the Scope of a Methodological Inquiry (Precise Definition of What Is Meant by the Logic of Appraisal of Scientific Theories) and Review the Work of Popper and Lakatos in the Philosophy of Science. We Then Use Their Results to Develop a Rational Structure of Scientific Activity. We Identify and Analyse Both a Micro and Macro Framework for the Process of Appraisal and Single Out the Importance of So-Called 'Fundamental Assumptions' in Creating Externalities in the Appraisal Process Which Forces Us to Adop a Multi-Level Analysis. Special Attention Is Given to the Role and Significance of the Abstraction Process and the Use of Assumptions in General. the Proposed Structure of Scientific Activity Is Illustrated with Examples From Economics.

Risk Aversion, Intertemporal Substitution, and Option Pricing

This paper develops a general stochastic framework and an equilibrium asset pricing model that make clear how attitudes towards intertemporal substitution and risk matter for option pricing. In particular, we show under which statistical conditions option pricing formulas are not preference-free, in other words, when preferences are not hidden in the stock and bond prices as they are in the standard Black and Scholes (BS) or Hull and White (HW) pricing formulas. The dependence of option prices on preference parameters comes from several instantaneous causality effects such as the so-called leverage effect. We also emphasize that the most standard asset pricing models (CAPM for the stock and BS or HW preference-free option pricing) are valid under the same stochastic setting (typically the absence of leverage effect), regardless of preference parameter values. Even though we propose a general non-preference-free option pricing formula, we always keep in mind that the BS formula is dominant both as a theoretical reference model and as a tool for practitioners. Another contribution of the paper is to characterize why the BS formula is such a benchmark. We show that, as soon as we are ready to accept a basic property of option prices, namely their homogeneity of degree one with respect to the pair formed by the underlying stock price and the strike price, the necessary statistical hypotheses for homogeneity provide BS-shaped option prices in equilibrium. This BS-shaped option-pricing formula allows us to derive interesting characterizations of the volatility smile, that is, the pattern of BS implicit volatilities as a function of the option moneyness. First, the asymmetry of the smile is shown to be equivalent to a particular form of asymmetry of the equivalent martingale measure. Second, this asymmetry appears precisely when there is either a premium on an instantaneous interest rate risk or on a generalized leverage effect or both, in other words, whenever the option pricing formula is not preference-free. Therefore, the main conclusion of our analysis for practitioners should be that an asymmetric smile is indicative of the relevance of preference parameters to price options.

Intertemporal Social Evaluation

Intertemporal social-evaluation rules provide us with social criteria that can be used to assess the relative desirability of utility distributions across generations. The trade-offs between the well-being of different generations implicit in each such rule reflect the underlying ethical position on issues of intergenerational equity or justice. We employ an axiomatic approach in order to identify ethically attractive socialevaluation procedures. In particular, we explore the possibilities of using welfare information and non-welfare information in a model of intertemporal social evaluation. We focus on the individuals’ birth dates and lengths of life as the relevant non-welfare information. As usual, welfare information is given by lifetime utilities. It is assumed that this information is available for each alternative to be ranked. Various weakenings of the Pareto principle are employed in order to allow birth dates or lengths of life (or both) to matter in social evaluation. In addition, we impose standard properties such as continuity and anonymity and we examine the consequences of an intertemporal independence property. For each of the Pareto conditions employed, we characterize all social-evaluation rules satisfying it and our other axioms. The resulting rules are birth-date dependent or lifetime-dependent versions of generalized utilitarianism. Furthermore, we discuss the ethical and axiomatic foundations of geometric discounting in the context of our model.

The Discipline of Economics and Economic Cycles

In This Article, It Is Argued That the Long International, Financial and Economic Cycle (50-60 Years) Is More Than a Statistical Aberration, and Is the Result of Institutional Political, Financial and Economic Conditions Which Are Recurrent. It Is Proposed As an Hypothesis That the Breakdown of International Monetary Systems Is At the Origin of Hte Financial and Economic Long Cycle. Such a Breakdown Starts a Process of Unexpected Inflation, of Balance of Payments Imbalances and of International Indebtedness in a Key-Currency. the Last Stage of This Process Is Characterized by Disinflation, a Speculative Stock Market Boom and a Period of Debt-Liquidation Which Negatively Affect the Real Side of the Economy. Without an International and Automatic Mechanism to Correct the Financial and Economic International Imbalances, the World Economy Runs the Risk of Getting More and More Unstable Until the Turning Point. International Monetary Cooperation Could Contribute in Alleviating the Negative Spillovers Accompanying Hte Adjustment of These Imbalances.

ADPIC et brevets pharmaceutiques: le difficile accès des pays en développement aux médicaments?

L'Accord sur les Aspects des Droits de Propriété Intellectuelle qui touchent au commerce constitue l'un des principaux piliers des accords de l'Uruguay Round. C'est aussi l'un des plus controversés. Cet Accord renforce les droits de propriété intellectuelle, les associe au commerce et introduit une norme mondiale ayant force exécutoire. La mise en application de cet Accord, qui suppose notamment de reconnaître et de renforcer la protection des produits et procédés pharmaceutiques par des brevets, pose des problèmes particuliers aux pays en développement vu le manque de ressources professionnelles, financières et d'infrastructure. La manière dont se fait l'interprétation de cet Accord peut avoir d'importantes répercussions sur les politiques de santé publique et, en particulier, sur l'accès des populations aux médicaments. Soumis aux pressions des pays riches et des groupes pharmaceutiques, les gouvernements des pays en développement se retrouvent parfois pieds et poings liés et n'utilisent pas les flexibilités prévues à leur avantage dans l'Accord, ce qui rend la situation sanitaire de leur population encore plus précaire. Cette étude décrit les principaux acteurs et les étapes importantes de la négociation de l'Accord, ainsi que les différentes adaptations qui en ont été faites sous les pressions contradictoires des nombreux protagonistes. Elle donne des explications sur les mécanismes en place et les conséquences possibles de l'entrée en vigueur de l'Accord sur l'accessibilité des pays en développement aux médicaments.

An Egalitarian Argument in Favour of Free Access to Healthcare and Rationing

La pensée égalitariste a traditionnellement promu l’idéal d’un système de santé universel, gratuit et accessible à tous les membres de la société. J’appuie cette position en répliquant tout d’abord à la critique qui prétend que les riches tireraient plus d’avantages que les pauvres de la gratuité du système de santé. J’ouvre ensuite la réflexion sur ce qui me semble être un enjeu crucial pour l’avenir des systèmes modernes de santé : le rationnement de l’offre. Cette idée ne plaît généralement pas à la population, aux décideurs politiques et à de nombreux égalitaristes. Je considère pourtant que les principaux arguments invoqués contre le rationnement sont incohérents ou faussement égalitaristes. La gratuité des services de santé n’est pas incompatible avec la limitation de l’offre publique.

Is There Personal Identity in Economics?

John B. Davis explores the question of what the economic individual is. He bases his considerations of orthodox economics on the assumption that these theories implicitly rely on a conception of the individual that has its origin in Locke’s idea of the self as subjective inwardness. Economic history then is the attempt to deal with Locke’s inherent problems that this view involved. If neoclassical economics still has aspects of human psychology, mainstream economics dropped the subjective concept of the individual out of their considerations. However, Davis demonstrates that even the neoclassical concept of the individual fails to pass the existence test of individual identity. The latter is an idea developed in analogy to philosophers’ concern about personal identity and examines if the individual can be distinguished among different individuals and if he or she can be reidentified as the selfsame individual through time. The failure of the theory of the individual in orthodox economics led Davis to develop a concept of a socially embedded individual in accordance with heterodox accounts of economics. He submits this conception to the same test of individual identity. It appears that the socially embedded individual can be said to hold an identity in specific circumstances.
