During the past few decades, the interest of economists in the sources of long-term economic growth has led an increasing number of them to focus on the role of innovation in creating that growth. Although some researchers have always been interested in this topic, the groundbreaking work of Solow (1957), Nelson (1959) and Arrow (1962) made many other economists recognize the central role played by innovation in almost all spheres of economic activity. The Economics and Econometrics of Innovation presents a valuable overview of the work of the world's most renowned experts in the field of innovation and technical change. It collects 22 outstanding contributions that reflect the results of the vast, worldwide research efforts and remind us of the importance of economic incentives in shaping and directing innovative activities. The volume presents an edited selection of papers that were first presented at the 10th International ADRES conference. One particular goal of this book is to bring out the complementary nature of the various approaches to innovation, and to facilitate in-depth dialogues both between microeconomists and macroeconomists, and between theoreticians and econometricians. General topics that are considered range from the economy-wide effects of innovation on growth and employment to the variation of individual firm innovative performance; from the analysis of networks and standardization to the role of intellectual property rights and the assessment of knowledge spillovers. Besides the wealth of information presented in the chapters, readers of this volume will also appreciate the value of examining a single question from different angles and by using different methods.

Cet ouvrage présente une étude systématique des prix industriels en France durant les vingt dernières années. Le phénomène fondamental de l'inertie des prix, dont on connaît le rôle important dans les politiques économiques conjoncturelles, est analysé ici aussi bien au niveau de la théorie qu'au niveau de l'économétrie appliquée. Une réponse est apportée à des questions essentielles concernant la spécificité du mouvement inflationniste en France, les particularités des grands secteurs d'activité, la dynamique des prix industriels au cours des périodes successives de forte croissance et de crise, le rôle des variables de structure industrielle.

Les deux traversées du judaïsme, thématique et historique, proposées dans cet ouvrage, conduisent à plusieurs observations. D’abord, l’existence de lectures diversifiées, sans qu’aucune d’elles n’exclue les autres. Ensuite, une très forte capacité à s’adapter aux transformations historiques. Deux forces motrices sont présentes : l’inspiration et la tradition. Elles permettent de comparer le judaïsme biblique au judaïsme rabbinique. Le judaïsme biblique a mis l’accent sur les réalités que traverse la nation ; le judaïsme rabbinique s’est polarisé autour de la tradition. Le dernier âge du judaïsme est celui des ruptures. Aujourd’hui, un enjeu important s’impose en Israël : les tensions sociales que provoquent les projets du gouvernement issu des élections de 2022, sont les héritières du conflit entre les deux forces motrices du judaïsme. C’est à l’ensemble de ces questions que s’adresse l’ouvrage, nourri de multiples travaux, tant universitaires que de la tradition juive.

In this paper, we revisit the issue of licensing 'weak' patents under the shadow of litigation. Departing from the seminal paper by Farrell and Shapiro [2008], we consider innovations of any size and not only 'small' innovations, and we allow the number of licensees to be less than the number of firms in the downstream industry. It is shown that the optimal two-part tariff license from the patent holder's perspective may either deter or trigger litigation, and conditions under which each case arises are provided. We also reexamine the claim that the licensing revenues from 'weak' patents overcompensate the patent holder relative to what a natural benchmark would command. Finally we suggest two policy levers that may alleviate the harm raised by the licensing of 'weak' patents.
