Working Paper Series Financial Fraud and Investor Awareness We study a retail financial market with naive investors who are unaware of the possible financial fraud. In our model, firms strategically choose whether to offer normal or fraudulent products to possibly unaware investors. Having new firms in the market makes offering normal products less profitable and thus discourages firms from behaving honestly. In a leader-follower environment, an honest firm may sell a normal product to sophisticated investors, while a dishonest firm targets only naive investors. By Zhengqing Gui, Xiaojian Zhao

Working Paper Series A Model of Trade with Endogenous Product Design We study a model of international trade in which firms choose between a board product design that targets mainstream consumers, and a niche product design that targets specific market segments. Assuming that local firms have absolute advantage in providing niche products to the local market, we show that in equilibrium, the more efficient firms adopt a board design and export whereas the less efficient firms adopt a niche design and do not export.
