We analyze how consumer preferences for one-stop shopping affect the bargaining relationship between a retailer and its suppliers. One-stop shopping preferences create demand complementarities among otherwise independent products which lead to two opposing effects on upstream merger incentives:...

We study sequential bargaining between two unions and a single firm. Parties bargain bilaterally and efficiently (over wage and employment). The unions' workforces can be substitutable ("tariff competition") or complementary ("tariff plurality" or "craft unionism"). If unions are substitutable,...

Considering a vertical structure with perfectly competitive upstream firms that deliver a homogenous good to a differentiated retail duopoly, we show that upstream fixed costs may help to monopolize the downstream market. We find that downstream prices increase in upstream firms'fixed costs when...

Im Zuge der Föderalismusreform wurden die gesetzlichen Ladenschlussbestimmungen in den meisten deutschen Bundesländern kürzlich gelockert. Dies ist ein Schritt in die richtige Richtung, um einen Anstieg von Produktivität und Wachstum im deutschen Einzelhandel zu bewirken. Allerdings birgt...

Die von der Bundesregierung geplante Verschärfung der Preissetzungsregeln im Einzelhandel sieht vor, dass Einzelhändler Güter nicht mehr zu Preisen verkaufen dürfen, die unter den Einstandspreisen liegen. Eine solche Preispolitik ist schon heute unzulässig, wenn damit kleinere Konkurrenten...

Das DIW Berlin veranstaltete am 26. Oktober dieses Jahres den 2. Wissenschaftlichen Roundtable "Informationsgesellschaft und Wettbewerb", der die Praxistauglichkeit des "More Economic Approach" in der europäischen Wettbewerbspolitik zum Gegenstand hatte. Mit dem "More Economic Approach" gewinnt...

We re-examine the Nash bargaining solution when an upstream and a downstream firm bargain over a linear input price. We show that the profit sharing rule is given by a simple and instructive formula which depends on the parties' disagreement payoffs, the profit weights in the Nash-product and...
