Prof. Dr. Tomaso Duso leitet die Abteilung Unternehmen und Märkte am Deutschen Institut für Wirtschaftsforschung (DIW Berlin). Er ist Professor für empirische Industrieökonomie an der Technischen Universität Berlin. Er berät unter anderem die Europäische...
We analyze clients’ contract choices in auctions where Dutch law firms compete for standard cases such as labor disputes for individuals and collecting debts for businesses. In the auctions, lawyers can submit bids with any fee arrangement they prefer, including an hourly rate, a fixed fee, and a ‘mixed fee’: a time-capped fixed fee plus an hourly rate for any additional hours should the case take ...
It is striking that economists in particular firmly believe in the benefits of rule-binding, even though this belief runs counter to the standard assumption of economic theory that we humans are self-interested and therefore extremely resourceful when it comes to circumventing inconvenient government regulations, e.g. taxes. In Public Choice Theory, politicians are even assumed to have nothing but ...
We study a merger between two Dutch supermarket chains to assess its effect on the depth as well as composition of assortment. We adopt a difference-in-differences strategy that exploits local variation in pre-merger competitive conditions and thus in the merger outcomes. To define our control group, we account for selection on observables through a matching procedure. We observe that, after the merger, ...
We study how budget constraints affect effort provision in sequential elimination tournaments. Our main result is that the introduction of budget constraints has two opposing effects on the initial effort of the unconstrained contestants, and leads to a non-monotonicity of this effort. This implies that if the budget asymmetry is not too large, total first-stage effort from unconstrained contestants ...
Eine Folge der Regenkatastrophe sind die immensen Kosten der Gebäudeschäden. Hier hilft eine Versicherungspflicht – die auch künftige Klimarisiken reduzieren kann. Der Klimawandel hat dieser Tage gezeigt, welche katastrophalen Folgen er hat: Sturmtief Bernd ist über Nordrhein-Westfalen, Rheinland-Pfalz, das Saarland und Teile Hessens gezogen und hat durch extremen Dauerregen ...
Wirtschaftspolitik in einer sozialen Marktwirtschaft möchte Wohlstand schaffen und verteilen. Dies zeigt sich in den Wahl- und Regierungsprogrammen auf Bundesebene seit 2002, allerdings mit sehr unterschiedlichen Akzenten. Zur Analyse wird deshalb die relative Häufigkeit der Begriffe „Soziales“ und „Wettbewerb“ in Programmen errechnet. Der daraus gebildete S/W-Koeffizient zeigt die Positionierung ...
We study the role of alliance governance in the behavior of partners in alliances with different degrees of competition. Using data from a lab experiment on 1,009 alliances and 31,662 partners' choices, we explore whether and how alliances succeed in different competitive scenarios, contingent on the use of formal governance mechanisms (termination clauses) and the number of partners in the alliance. ...
The Berlin IO Day is a one-day workshop sponsored by the Berlin Centre for Consumer Policies (BCCP) and supported by the Berlin's leading academic institutions, including DIW Berlin, ESMT Berlin, Freie Universität Berlin, Humboldt-Universität zu Berlin, and Technische Universität Berlin. The aim is to create an international forum for high quality research in Industrial Organization...
