School of Business and Management Department of Economics 172 Department of Economics Search Obfuscation and Position Auction on Online Platforms Supervisor: AU Pak Hung / ECON Student: LEUNG Chin Pang / ECOF Course: UROP 2100, Fall We investigate the incentives of an online selling platform for introducing randomness in its position auction for the top spot in a consumer's search results for a specific keyword. Base on the last progress report. We further develop the model on finding the optimal case as the platform manipulates randomness, when the consumers expect the worse-fit seller bidding higher. The non-trivial tradeoff on the last progress report was clarify. This progress report would present the further analysis on the simple two-seller model by substuition on different parameters, it helps to find the optimal solution for the non-trivial case and compare with another case. Search Obfuscation and Position Auction on Online Platforms Supervisor: AU Pak Hung / ECON Student: LEUNG Chin Pang / ECOF LI Ziyuan / ECOF TAO Junheng / MAEC Course: UROP 3200, Spring UROP 3200, Spring UROP 1100, Spring Based on the previous progress report, we further investigate the incentives of an online selling platform for introducing randomness in the position auction for the top spot in the search results according to a specific keyword. We found that when shoppers (consumers who have room to visit more firms) are abundant, and or the profit levels of the sellers are close, the platform has incentives to introduce randomness into the position auction. Comparative statics with respect to the optimal search diversion show that the platform extracts a bigger auction fee the less shoppers are on the platform. Hong Kong Financing and the Silk Road Supervisor: COOK David Edward / ECON Student: AU Kam Ho / MAEC Course: UROP 1000, Summer This paper is the preliminary research on the possible sources of financing for the Silk Road projects and their respective costs. It also finds out the role of Hong Kong and China in funding these projects. The possible methods of financing the projects (who to borrow the capital from) will be discussed first, followed by a comparison of the borrowing costs between different financing options. The most interested group of this research is the Caucusus and Central Asia (CCA) countries, namely (1) Armenia, (2) Azerbaijan, (3) Georgia, (4) Kazakhstan, (5) Kyrgyzstan, (6) Tajikistan, (7) Turkmenistan, and (8) Uzbekistan (in alphabetical order). An analysis of the Silk Road projects funding in CCA countries will be given at last.
