    Supplier Fixed Costs and Retail Market Monopolization

    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 both intra- and interbrand competition exist. Our findings contradict the common wisdom that fixed costs ...

    The Welfare Impact of Parallel Imports: A Structural Approach Applied to the German Market for Oral Anti-Diabetics

    We investigate the welfare impact of parallel imports using a large panel dataset containing monthly information on sales, ex-factory prices, and further product characteristics for all 649 anti-diabetic drugs sold in Germany between 2004 and 2010. We estimate a two-stage nested logit model of demand, and on the basis of an oligopolistic model of multi-product firms, we then recover the marginal costs ...

    Crop Failures and Export Tariffs

    We analyse a stylized model of the world grain market characterized by a small oligopoly of traders with market power on both the supply and demand side. Crops are stochastic and exporting countries can impose export tariffs to protect domestic food prices. Our first results is that export tariffs are strategic complements and that for poor harvests equilibrium tariffs can explode (shedding some light ...

    Price Guarantees, Consumer Search, and Hassle Costs

    The paper deals with the competitive effects of price guarantees in a spatial duopoly where consumers can search for lower prices but have to incur hassle costs if they want to claim a price guarantee. It is shown that symmetric equilibria with and without price guarantees exist but price guarantees will have no effect on prices if search costs are low, hassle costs are high and the number of uninformed ...

    From Boom to Bust? A Critical Look at US Shale Gas Projections

    US shale gas production is generally expected to continue its fast rise. However, a cautious evaluation is needed. Shale gas resource estimates are potentially overoptimistic and it is uncertain to which extent they can be produced economically. Moreover, the adverse environmental effects of ever more wells to be drilled may lead to a fall in public acceptance and a strengthening of regulation. The ...

    Joint Customer Data Acquisition and Sharing among Rivals

    It is increasingly observable that in different industries competitors jointly acquire and share customer data. We propose a modified Hotelling model with two-dimensional consumer heterogeneity to analyze the incentives for such agreements and their welfare implications. In our model the incentives of firms for data acquisition and sharing depend on the willingness of consumers to switch brands. Firms ...

    How Does Fuel Taxation Impact New Car Purchases? An Evaluation Using French Consumer-Level Data

    This study evaluates the impact of fuel prices on new car purchases, using exhaustive individual-level data of monthly registration of new private cars in France from 2003 to 2007. Detailed information on the car holder enables us to account for heterogeneous preferences across purchasers. We identify demand parameters through the large oil price fluctuations of this period. We find that the sensitivity ...

    Financial Incentives for Low Carbon Investment: Dissertation

    Zur Bekämpfung des Klimawandels haben politische Entscheidungsträger auf europäischer, nationaler und regionaler Regierungsebene CO2-Reduktionsziele formuliert, die erhebliche Investitionen erfordern. Studien haben zahlreiche Marktbarrieren ermittelt, die diese Investitionen verhindern. Zur Überwindung dieser Barrieren wurden regulatorische, preis- und informationsbasierte Politikinstrumente implementiert. ...

    Climate Protection through Biochar in German Agriculture: Potentials and Costs

    In recent years, there has been much discussion about biochar - a carbonaceous product made of biomass - as a promising technique for mitigating climate change. In particular, this method has the potential to remove carbon dioxide from the atmosphere for the long term by incorporating biochar into the soil while enhancing soil fertility at the same time. A research project conducted by DIW Berlin calculated ...
