Industries are economically linked through customer-supplier trade flows. We show theoretically and empirically that industry shocks propagating along this inter-sectoral trade network can feed back to the originating industry, causing an “echo” – intermediate-term autocorrelation in returns. Adopting techniques from graph theory, we find that the strength of the trade network feedback is a cru...

Informational Efficiency of Credit Default Swap and Stock Markets: The Impact of Credit Rating Announcements This Paper analyses the response of stock and credit default swap (CDS) markets to rating announcements by the three major rating agencies during 2000-2. Applying event study methodology, we examine whether and how strongly these markets respond to rating announcements in terms of abnorm...

Insider trading in the credit derivatives market has become a significant concern for regulators and participants. This paper attempts to quantify the problem. Using news reflected in the stock market as a benchmark for public information, we find significant incremental information revelation in the credit default swap market under circumstances consistent with the use of non-public informatio...

We consider a cheap talk game with a sender who has a reputational concern for an ability to predict a state of the world correctly, and where receivers may misunderstand the message sent. When communication between the sender and each receiver is private, we identify an equilibrium in which the sender only discloses the least noisy information. Hence, what determines the amount of information ...

Abstract A total of 24 oat genotypes were evaluated across 9 environments using a randomized complete block design with 3 replications. The combined analysis variance indicated that grain yield was significantly affected by genotype, environment, and genotype environment interaction (GEI). environment's main effect explained 44.62% the variation, whereas GEI captured 28.84% 26.54%, respectively...

We examine the relation between institutional ownership in acquiring firms and their post takeover stock performance. We find that negative long-run abnormal returns appear to decline (in economic and statistical terms) as the extent and persistence of institutional ownership increase, after accounting for the size, book-to-market and method of payment effects. Given the unusually high uncertai...

This paper investigates the mechanism through which short selling of a bank’s stocks can trigger the failure of the bank. In the model, creditors, who learn information from stock prices, will grow increasingly unsure about the bank’s true fundamentals in facing noisier stock prices; thus a run on the bank is more likely because of creditors’ concave payo¤. Understanding this, speculators condu...
