What is the social value of innovations in Schumpeterian growth models? This issue is tackled by introducing the concept of Lindahl equilibrium in a standard endogenous growth model with vertical innovations which is extended by explicitly considering knowledge diffusion. Assuming that knowledge...

Food purchases differ substantially across countries. We use detailed household level data from the US, France and the UK to (i) document these differences; (ii) esti- mate a demand system for food and nutrients, and (iii) simulate counterfactual choices if households faced prices and...

A major policy issue in standard setting is that patents that are ex-ante not that important may, by being included into a standard, become standard-essential patents (SEPs). In an attempt to curb the monopoly power that they create, most standard-setting organizations require the owners of...

This paper investigates the reliability of SVARs to identify the dynamic effects of news shocks. We show analytically that the dynamics implied by SVARs, using both long–run and short–run restrictions, are biased. However, the bias vanishes as long as news shocks account for most of the...

What can evolutionary biology tell us about male-female differences in preferences concerning family matters? Might mothers be more solicitous toward offspring than fathers, for example? The economics literature has documented gender differences—children benefit more from money put in the...

This paper studies the determination of informal long-term care (family aid) to de- pendent elderly in a worst case scenario concerning the harmonyof family relations. Children are purely sel…sh, and neither side can make credible commitments (which rules out e¢ cient bargaining). The model is...

We examine the impact of the licensing policies of one or more upstream owners of essential intellectual property (IP hereafter) on the variety offered by a downstream industry, as well as on consumers and social welfare. When an upstream monopoly owner of essential IP increases the number of...

Cet article présente les contributions originelles et essentielles de T. Sargent et C. Sims à la modélisation macro-économétrique. Après avoir exposé leur critique de la modélisation existante, cet article s'attache à préciser l'originalité de leurs approches respectives. La...

L’objet de cet article est d’examiner, à la lumière de deux solutions majeures de la théorie des jeux coopératifs, les coalitions/négociations électorales qui ont lieu dans le cas où le mode de scrutin est un scrutin proportionnel avec listes bloquées, prime au gagnant et comportant...

We develop a model where individuals all have the same probability of becoming dependent and vote over the social long term care insurance contribution rate before buying additional private insurance and saving. We study three types of behavioral biases, all having in common that agents...
