Rating Shopping and Rating Inflation: Empirical Evidence from Israel

The collapse of structured bond ratings during the 2007-2008 financial crisis called attention to the possibility of rating inflation due to lowered rating standards and rating shopping. Nevertheless, little empirical evidence has been offered for this prospect. The Israeli corporate credit rating market serves as solid ground for investigating this matter. In this study, we use data on corporate bond ratings assigned by two local rating agencies affiliated with S&P and Moody’s during the period 2004-2009. We show that while one agency (Midroog) systematically assigned higher ratings, the ratings of the other agency (S&P-Maalot) were inflated due to rating shopping. These conclusions are based on several findings: the presence of selection bias in dual ratings, the superior accounting features of firms rated by S&P-Maalot relative to those similarly rated by Midroog, and the greater tendency of single ratings by S&P-Maalot to be downgraded. We confirm the predictions of recent theoretical studies that rating inflation may occur even when the value of the rating agencies derives from their reputation.

A re-examination of value-creation through strategic alliances

This paper uses a sample of 335 firms participating in strategic alliances in order to re-examine the value creation through strategic alliances. We show that the immediate positive response of stock markets to new strategic alliances is followed by negative abnormal returns. Twenty days after announcements, cumulative positive abnormal return is only evident for the firms with the highest stock market’s response to the announcement. We relate the positive abnormal returns reported in previous research to the presence of short-run over-reaction in stock markets and conclude in the market’s ability to identify the more valuable alliances.Strategic alliance; over-reaction; momentum

Good news, bad news and rating announcements: An empirical investigation

In this paper we employ a new approach to test the contribution of information in rating announcements. This is the first study to test and corroborate how the CDS market responds to rating actions after controlling for the presence of concurrent public and private information. We show that since the clustering of rating announcements characterizes economically significant developments, the common practice of using "uncontaminated" samples underestimates market response. As in previous studies, we find that the market response to bad news is stronger than to good news. Nevertheless, bad news and negative rating announcements tend to cluster. Therefore, the residual contribution of negative rating announcements is small and in some cases insignificant. Positive rating announcements are less frequent and less clustered, though their residual contribution is still significant.Credit Default Swaps Credit risk Credit rating Event study

Bailouts and the Modeling of Bank Distress

In this article, we develop a model for predicting distress events among large banks. We show that a bailout possibility induces different behaviors among small and large banks, and the proposed failure prediction model for large banks is thus considerably different from that for small banks. Major bank-level fundamentals show opposite conjecture directions for large versus small banks. The Tier 1 capital ratio, which is under the scrutiny of regulators and investors, has almost no distress prediction power among large banks. However, banks rescued by governments tend to maintain a lower Tier 1 ratio. The cost of funding in large banks is negatively correlated with the probability of failure, reflecting the fact that lenders internalize the too-big-to-fail (TBTF) policy and demand a lower interest rate from TBTF banks

A reexamination of value creation through strategic alliances

This paper uses a sample of 335 firms participating in non-equity and minority equity strategic alliances to reexamine value creation through strategic alliances. We show that the immediate positive response of stock markets to new strategic alliances is followed by negative abnormal returns. Twenty days after announcements, a cumulative positive abnormal return is only evident for those firms with the highest stock market response to the announcement. We relate the positive abnormal returns reported in previous research to the presence of short-run overreaction on stock markets and conclude with the market's ability to identify those alliances that are more valuable.strategic alliances, market overreaction, event study, value creation, stock markets, market response, abnormal returns,
