Inequality and Welfare: Is Europe Special? (Chapter 12)Book chapterAlain Trannoy, In: Economics without Borderss - Economic Research for European Policy Challenges, L. Matyas, R. Blundell, E.

This chapter reviews the literature about inequality and welfare with a particular focus on whether Europe has a special sensitivity to these matters or specific outcomes. It is argued that both statements are likely to be true, which raises the possibility of a causal link. Europe has relatively good results in terms of inequality and welfare in comparison with other continents and more specifically America, because these issues matter for European people. Still, research needs to be fostered in at least 5 areas that are detailed at the end of this review. Specific attention is devoted to the contribution of other social sciences and natural sciences (cognitive science) to the development of our knowledge for the field of inequality and welfare.

Philosophie économique, un état des lieux - IntroductionBook chapterJean-Sébastien Gharbi et Gilles Campagnolo, In: Philosophie économique, un état des lieux, 2017-02, pp. 3-48, Éditions matériologiques, 2017

En France, la tradition de philosophie économique est brillamment illustrée : la publication d’un « état des lieux » en fournit le référent francophone, un panorama aussi complet que possible afin de s’y orienter. La critique que peut porter la philosophie économique se comprend comme un partage bien pensé entre bon et mauvais usage de la raison, comme méthodologie ainsi que comme ontologie, une discussion du rôle des sciences adjacentes (comme la psychologie), de l’usage des normes, des modes de raisonnement, l’explicitation des bases trop souvent dans l’ombre de l’analyse économique vue en ses champs d’application multiples : simulation, analyse institutionnelle, finance et autres enjeux.

Networked Markets and Relational ContractsBook chapterMatt Elliott, Benjamin Golub et Matt V. Leduc, In: Web and Internet Economics (13th International Conference, WINE 2017, Bangalore, India, December 17–20, 2017, Proceedings), N.R. Devanur et P. Lu (Eds.), 2017, pp. 402, Springer International Publishing, 2017

Empirical studies of commercial relationships between firms reveal that (i) suppliers encounter situations in which they can gain in the short run by acting opportunistically—for example, delivering a lower quality than promised after being paid; and (ii) good conduct is sustained not exclusively by formal contracts but through informal relationships and the expectation of future business. In such relationships, the need to offer each supplier a large enough share of future business to deter cheating limits the number of supply relationships each buyer can sustain. The market thus becomes networked, with trade restricted to durable relationships. We propose and analyze a simple dynamic model to examine the structure of such overlapping relational contracts in equilibrium. Due to exogenous stochastic shocks, suppliers are not always able to make good on their promises even if they wish to, and so links are constantly dissolving and new ones are forming to take their place. This induces a Markov process on networks. We study how the stationary distribution over networks depends on the parameters—most importantly, the value of trade and the probability of shocks. When the rate at which shocks hit increases, as might happen during an economic downturn, maintaining incentive compatibility with suppliers requires promising each more future business and this necessitates maintaining fewer relationships with suppliers. This results in a destruction of social capital, and even if the rate of shocks later returns to its former level, it can take considerable time for social capital to be rebuilt because of search frictions. This creates a novel way for shocks to be persistent. It also suggests new connections between the theory of relational contracting, on the one hand, and the macroeconomic analysis of recessions, on the other.

The Determinants of Consumer Price Dispersion: Evidence from French SupermarketsBook chapterNicoletta Berardi, Patrick Sevestre et Jonathan Thébault, In: The Econometrics of Multi-Dimensional Panels: Theory and Applications, L. Matyas (Eds.), 2017, Volume 50, pp. 427-449, Springer Verlag, 2017

In this chapter, we characterize the dispersion of grocery prices in France based on a large original data set of prices in more than 1500 supermarkets across the country. On average across products, the 90 th percentile of relative prices is 17 percentage points higher than the 10 th . The mean absolute deviation from quarterly average product prices is 5% on average in the French retail sector, and the standard deviation of relative prices is 7%.We show that temporary sales and promotions offer a limited explanation of the observed price dispersion, while the permanent component of price dispersion largely dominates. We find that in France price dispersion across stores essentially results from persistent heterogeneity in retail chains’ national pricing. Indeed, consumer prices are largely determined at a national level by retail groups’ bargaining power with producers and by retail chains’ positioning. We also show, however, that local conditions regarding demand and local competition between supermarkets do explain prices observed in local markets, though to a much lower extent.
