Prof. Alp Atakan: “Auctions, Actions, and the Failure of Information Aggregation”
Koç University, Istanbul, Turkey

Abstract: We study a market in which k identical and indivisible objects are allocated using a uniform-price auction where z > k bidders each demand one object. Before the auction, each bidder receives an informative but imperfect signal about the state of the world. The good that is auctioned is a common-value object for the bidders, and a bidder’s valuation for the object is determined jointly by the state of the world and an action that he chooses after winning the object but before he observes the state. We show that there are symmetric equilibria in which the auction price is completely uninformative about the state of the world and aggregates no information even in an arbitrarily large auction. In the equilibrium that we construct, because prices do not aggregate information, agents have strict incentives to acquire costly information before they participate in the market. Also, market statistics other than price, such as the amount of rationing and bid distributions contain extra information about the state. Our findings sharply contrast with past work which shows that in large auctions where there is no ex-post action, the auction price aggregates information.

Abstract:
Research in the field of terrorism is relatively new and has attracted researchers from different disciplines for only a short time. Economic literature studies both the causes and consequences of terrorism, and this thesis contributes to the literature addressing both of these aspects.The first two chapters focus on consequences of terrorist attacks on investments, while the third chapter addresses causes of terrorist attacks across national borders.
In the first chapter, co-authored with Randall K. Filer, we use an unbalanced panel of over 160 countries over a 25 year period to show that terrorism has a significant negative effect on foreign direct investment (FDI). We find evidence that FDI flows are more sensitive to terrorism than either portfolio investments or external debt flows. We also show that terrorism has a negative spill-over effect on the FDI flows of neighboring countries and find evidence that cultural rather than geographical proximity matters most. The results of this chapter open new questions for further research. For example, future empirical studies may discover reasons for the higher sensitivity of FDI to terrorism than other flows of investments. Or, future studies can show more empirical evidence of factors that influence negative spill-over effects of terrorism on neighboring economies.
The results from the first chapter served as motivation for the second chapter, where I estimate the negative effect of terrorism on FDI flow between countries. I employ a sample of 23 countries that send FDI and 52 countries which receive it from 1995 to 2010, and use sample selection correction to address the problem of missing observations. I estimate that an increase of terrorist attacks by one standard deviation is associated with a 12 percent decrease of FDI flow from sender to receiver. I also find that there is a negative spill-over effect of terrorism among investors. Finally, I show that, in the last 16 years, perceived political stability has been the most important factor in attracting FDI. The results of this study suggest that in addition to general security conditions equal to all investors in the host market, there is additional terrorist attack risk for investment for each individual investor. With available data on terrorist attacks and FDI flow between countries, future studies can examine in more detail how this risk can be predicted, and which factors influence it. While the two first chapters address the consequences of terrorist attacks, the last chapter studies its causes.
The third chapter, co-authored with Jitka Malečková, examines support for terrorism in public opinion and its relationship with terrorist attacks. We link the 2007 PEW survey data on opinions regarding the justification of suicide terror attacks on nine regional powers which are often regarded unfavorably by the populations of 16 countries of the Middle East, Africa, and Asia to the NCTC data on international terrorist attacks. We find a robust positive relationship between the share of the population in a country that both justifies suicide bombings and has an unfavorable opinion of another country, and terrorism originating from the former country. The results of this study suggest that policy designers can look at public support for terrorism as a proxy for its occurrence. Future studies can examine the demographic characteristics of those who support terrorism, or study the factors that may change public opinion over time. Finally, future research may study mechanisms by which public support is translated into action or recruitment for terrorist groups.
