题目：Preference, Confusion and Competition

主讲人：刘烁 北京大学光华管理学院应用经济学系 助理教授

主持人：陆卓然 复旦大学管理学院产业经济学系 助理教授

摘要：Do firms seek to make the market transparent, or do they confuse the consumers in their product perceptions? We show that the answer to this question depends decisively on preference heterogeneity. Contrary to the well-studied case of homogeneous goods, confusion is not necessarily an equilibrium in markets with differentiated goods. In particular, if the taste distribution is polarized, so that indifferent consumers are relatively rare, firms strive to fully educate consumers. By contrast, if the taste distribution features a concentration of indecisive consumers, confusion becomes part of the equilibrium strategies. The adverse welfare consequences of confusion can be more severe than with homogeneous goods, as consumers may not only pay higher prices, but also choose a dominated option, or inefficiently refrain from buying. Qualitatively similar insights are obtained for political contests, in which candidates compete for voters with heterogeneous preferences.

题目：Growing through Competition: the Reduction of Entry Barriers among Chinese Manufacturing Firms

主讲人：蒋荷露 上海财经大学高等研究院 助理教授

主持人：沈煌南 复旦大学管理学院产业经济学系 助理教授

摘要：Exploiting the gradualism of the Chinese economic reforms and cross-sectional variations in entry rates, we show empirical evidence from firm-level data that industries with higher entry rates achieve higher growth and a more competitive market struc- ture in subsequent years. We then embed firm entry into a model of endogenous productivity and market structure with heterogeneous firms and sectors, and calibrate it to the Chinese manufacturing sector in 2004-7. We find the positive impact of entry on growth is achieved primarily through a pro-competitive effect, whereby entry induces endogenously a larger fraction of industries to be more competitive in the economy. We quantify the contribution on growth from the reduction of entry barriers associated with the state-owned enterprise reforms in the late 1990s and early 2000s and find it explains 20% of the aggregate growth of the manufacturing sector from 2004-7. More generally, we highlight the critical role of reducing entry barriers in promoting competition and growth in developing countries.
