Un exemple de convergence en études médiévales : le droit canonique

Le Code de droit canonique, que l’on appelle aussi droit ecclésiastique, constitue le corpus législatif de l’Église catholique. Depuis son ébauche au Moyen-Âge jusqu’à présent, on découvre, à travers son évolution, la richesse morale, théologique, historique et sociologique de son contenu, malgré l’apparente froideur de la lettre. C’est donc avec une attitude d’ouverture qu’il convient d’aborder le code, de façon à faire apparaître, au-delà de sa rigueur, sa profondeur et sa richesse. Les collections de la Bibliothèque des lettres et sciences humaines de l’Université de Montréal sont en mesure d’appuyer ce dévoilement.

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.

Religion and Economic Growth: Was Weber Right?

Evidence of falling wages in Catholic cities and rising wages in Protestant cities between 1500 and 1750, during the spread of literacy in the vernacular, is inconsistent with most theoretical models of economic growth. In The Protestant Ethic, Weber suggested an alternative explanation based on culture. Here, a theoretical model confirms that a small change in the subjective cost of cooperating with strangers can generate a profound transformation in trading networks. In explaining urban growth in early-modern Europe, specifications compatible with human-capital versions of the neoclassical model and endogenous-growth theory are rejected in favor of a “small-world” formulation based on the Weber thesis.

The Bootstrap of Mean for Dependent Heterogeneous Arrays.

Presently, conditions ensuring the validity of bootstrap methods for the sample mean of (possibly heterogeneous) near epoch dependent (NED) functions of mixing processes are unknown. Here we establish the validity of the bootstrap in this context, extending the applicability of bootstrap methods to a class of processes broadly relevant for applications in economics and finance. Our results apply to two block bootstrap methods: the moving blocks bootstrap of Künsch ( 989) and Liu and Singh ( 992), and the stationary bootstrap of Politis and Romano ( 994). In particular, the consistency of the bootstrap variance estimator for the sample mean is shown to be robust against heteroskedasticity and dependence of unknown form. The first order asymptotic validity of the bootstrap approximation to the actual distribution of the sample mean is also established in this heterogeneous NED context.

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.
