À la différence du commerce BtoC, qui donne lieu depuis quarante ans à de très nombreux travaux, le commerce de gros (encore dénommé commerce inter-entreprises ou intermédiation BtoB) n'a pas vraiment retenu l'attention du milieu académique, posant la question de l'attractivité du secteur aux yeux de générations d'étudiants. Ainsi, pendant longtemps, les grossistes ont été présentés comme des acteurs passifs, non créateurs de valeur, incapables d'initier des démarches managériales et technologiques innovantes. Seuls seraient légitimes à revendiquer ces démarches ceux qui conçoivent et fabriquent les produits (les producteurs), ou bien ceux qui interagissent avec le consommateur final (les détaillants), privant de fait les entreprises du commerce de gros d'un rôle actif dans la modernisation des chaînes de valeur. Pourtant, le commerce de gros représente une activité économique considérable, tant par les volumes d'affaires en jeu, que par le nombre d'entreprises et les effectifs impliqués dans la plupart des pays occidentaux, mais aussi dans les pays en voie de développement. Un grand nombre de grossistes sont ainsi porteurs d'innovations majeures en matière de logistique et de gestion des relations. L'objectif est ici de donner à voir le potentiel que recèle ce type de commerce lorsqu'il est posé comme un objet d'investigation de première importance. Pour cela, il est nécessaire de se doter de nouveaux outils afin d'identifier les interrogations pouvant lui être rattachées, et y apporter des éléments de réponse. Cet ouvrage, original et pionnier, réalisé dans le cadre de la Chaire de Recherche CGI avec la collaboration d'EMLyon Business School et du Cret-log d'Aix-Marseille Université, s'adresse à un large public de lecteurs exigeants : chercheurs confirmés ou en formation, enseignants, étudiants en École ou à l'Université, consultants, et plus largement, managers de fonctions support et/ou impliqués dans des prises de décision stratégiques. Ils trouveront dans les différents chapitres, écrits par des auteurs de renommée internationale, à la fois une réflexion conceptuelle de haut niveau sur les logiques d'intermédiation, et des applications, particulièrement pertinentes, à une multiplicité de contextes et de secteurs d'activité.

International supply chains require the coordination of numerous activities across multiple countries and firms. This paper develops a theoretical model of supply chains in which the measure of tasks completed within a firm is determined by parameters that define transaction costs and the cost of coordinating more activities within the firm. The structural parameters that govern these costs explain variation in supply chain length as well as cross-country variation in gross-output-to-value-added ratios. The structural parameters are linked to comparative advantage along and across supply chains. The paper provides an analytical treatment of trade and welfare responses to trade cost change in a simple two-country model. To explore the models implications in a richer setting, the model is calibrated to match key observables in East Asia, and the calibrated model is used to evaluate implications of changes in model parameters for trade, welfare, the length of supply chains, and countries relative position within them.

Subsidies and cross-subsidies in the energy sector are common throughout Eastern Europe and Central Asia. In Belarus, revenues from an industrial tariff on electricity are used to cross-subsidize heating for households. Input-output (IO) data and a household consumption survey are used to analyze the distributional impacts of this cross-subsidization. This paper illustrates cost shares and electricity-intensity of different sectors and consumption categories and uses the IO data to obtain first-order estimates of the distributional incidence of policy reform. The paper then analyzes distributional impacts of subsidy reform with a Computable General Equilibrium model. Although poorer households benefit from reduced heating costs, the increase in prices of other consumer goods due to higher electricity prices more than offsets the benefits they receive from the subsidies. The analysis finds that the current cross-subsidies are regressive, and policy reform would be highly progressive.
