摘要：We present an endogenous growth model in which some firms devote resources to ner eloping higher-quality products (innovative R&D) and other firms devote resources to copying these products (imitative R&D). Although consumers benefit from the knowledge created by both types of R&D activities, only innovative R&D subsidies lead to faster economic growth; imitative R&D subsidies actually lead to slot-ver economic growth. A key assumption driving these conclusions is that R&D activities are subje...

摘要：In standard auctions, collusion among buyers eliminates bidding competition despite informational asymmetries. Collusion can, however, be imperfect when the situation involves externalities among buyers, that is, when a buyer is worse off if one rival wins the goon rather than if nobody gets it. For intermediate values of the externality and under various objective functions, the seller finds it optimal to design an auction that leads, in equilibrium, to a collusive outcome that is ex post ine...

摘要：In the first event-time analysis of the great merger wave of 1897-1903, we find that the consolidations created value for merger participants of 12% to 18%. We next find that competitors suffered significant value losses inconsistent with conventional monopoly behavior (i.e., trust-induced output reductions and price increases). This result might be explained by apprehensions of trust predation rather than expected efficiency, but further analysis suggests that this is unlikely. Revelation of ...

摘要：I study stable structures of efficiency-enhancing joint ventures among symmetric firms. Efficiency gains that accrue to a joint venture are assumed to increase with its size. The socially efficient industrywide joint venture is the stable outcome when membership of a joint venture is open to outside firms but typically not when membership can be restricted Members of a large joint venture want to restrict membership for strategic reasons-e.g., in order to keep rival firms' costs high. Side pay...

摘要：We study monopoly pricing of overlapping generations of a durable good. We consider two sorts of goods: those with an active secondhand market and anonymous consumers, such as textbooks, and those with no secondhand market and consumers who can prove that they purchased the old good to qualify for a discount on the new one, such as software. In the first case we show that the monopolist may choose to either produce or repurchase the old good once the new one becomes available, In the latter ca...

摘要：Using data from the 1979 and 1987 National Health Interview Survey (NHIS), we test whether smokers alter their smoking habits in the face of higher taxes. Smokers in high-tax states are more likely to smoke cigarettes higher in tar and nicotine. Although tares reduce the number of cigarettes consumed per day among remaining smokers, total daily tar and nicotine intake is unaffected. Young smokers, aged 18-24, are much more responsive to changes in taxes than are older smokers, and their total ...
