论文摘要1：We examine how reputation concerns induce a multinational to partly withhold its entry into a developing country under weak intellectual property rights (IPR) enforcement. Equilibrium IPR violations are shown to arise only in the presence of such concerns. Holding constant a multinational’s incentive to innovate, better IPR enforcement encourages entry, but reduces social welfare. The multinational’s incentive to innovate may be inversely U-shaped in the strength of IPR enforcement. If timed properly, however, stronger IPR enforcement can foster innovation without compromising social welfare.

论文摘要2：A model of heterogeneous firms with variety-specific fixed costs is developed and analyzed to study how multiproduct firms respond to globalization. In contrast with most existing models, the analysis demonstrates that more-productive firms may expand their product scope, which in turn may push up their average costs. A necessary and sufficient condition for scope expansion is that the fixed cost of introducing more varieties increases rapidly with the product scope. With increasing globalization, the percentage of scope-expanding firms diminishes and eventually becomes zero.
