the cost of market versus regulatory discipline in banking1 abstract we present evidence that insured deposit financing shields banks from the full costs of market discipline moody s downgrades indicators of increasing risk are associated with negative abnormal equity returns that are increasing in the bank s reliance on insured deposits moreover banks raise their use of insured deposits following increases in risk these findings cast doubt on the ability of capital market participants to effectively discipline bank behavior within the current regulatory environment more generally our findings highlight the potential for regulation to undermine market discipline in regulated industries

the effect of preferred stock rating changes on preferred and common stock prices abstract daily returns are used to investigate the effect of preferred stock rating change announcements on preferred and common stock prices announcements that are free of confounding events clean announcements significantly affect preferred stock prices however the effect occurs after the day of announcement mostly on event day 1 conversely there is no evidence clean announcements affect common stock prices larger preferred stock abnormal returns are associated with announcements that are contaminated by confounding events but the abnormal returns appear to be the result of the confounding events more than the rating change

changes in the probability of bankruptcy and equity value abstract work in finance suggests that changes in the probability of bankruptcy likely affect firm value by affecting perceptions of the cost of transacting with the firm in this paper accounting information from the balance sheet as well as the income statement is used in conjunction with ohlson s 1980 bankruptcy prediction model to calculate unexpected changes in the probability of bankruptcy for a sample of firms with a large estimated probability of bankruptcy sometime during the ten year study period unexpected changes in the probability of bankruptcy are useful in explaining security returns even after controlling for unexpected earnings

common stock returns and rating changes a methodological comparison this paper examines the adjustments in a firm s common stock price during the eleven months before and during the month of announcement of a bond rating change based on several different measures of abnormal security return the findings are consistent with the proposition that bond downgradings convey information to common stockholders for bond upgradings the price adjustments were statistically insignificant in the month of announcement although in the eleven preceding months upgraded firms exhibited positive abnormal returns while the results do not fully support earlier research we stress that the main contribution of this article lies in the scrutiny it gives to issues of methodology in assessing the possible price effects of bond reclassifications several recent studies have investigated the effects of changes in company debt classifications by the major bond rating agencies 1 these include four studies of the impact of a rating change on bond prices katz 19 hettenhouse and sartoris 14 grier and katz 12 and weinstein 25 and one study of the impact on common stock prices pinches and singleton 22 the findings of the bond price studies differ widely thus while katz and grier and katz suggest that trading rules based on the announced downgradings of industrial bonds may be moderately profitable hettenhouse and sartoris and weinstein analyzing bond yields and returns respectively find that there is no apparent opportunity to profit abnormally subsequent to the announcement of the change weinstein attributes these differences in results largely to issues of methodology and proceeds to investigate the effects of rating changes on bond prices using more refined risk adjustment techniques and portfolio estimation procedures

the effect of bond rating changes on common stock prices abstract the evidence in this paper suggests that downgrades by both moody s and standard and poor s are associated with negative abnormal stock returns in the two day window beginning the day of the press release by the rating agency significant negative abnormal performance can still be detected after eliminating observations containing obvious concurrent potentially contaminating news releases there is little evidence of abnormal performance on announcement of an upgrade significant abnormal returns are associated with announcements of additions to the standard and poor s credit watch list if either a potential downgrade or a potential upgrade is indicated

when social and economic goals meet the double dividend of improving farmers health capital in uganda abstractfocusing on the relationship between farmers health and agricultural productivity we explore the potential effects of improving the current health care fee policy in uganda using a microsimulated general equilibrium model we show that alternative health fee reduction strategies might increase the chances of achieving simultaneous growth poverty reduction and improved access to health for households while maximising the public spending effectiveness however these results seem very sensitive to the potential disruptive effects on public facilities that such a policy might generate so they must be contextualised within a broader perspective on the health system s efficiency

the impact and the spillover effect of a sovereign rating announcement on the euro area cds market abstract this paper analyzes the impact and the spillover effect of a sovereign rating announcement on the euro area cds market through the event study technique we demonstrate that downgrades and upgrades considerably affect financial markets the relevance of the impact is due to the introduction of new information after a rating change announcement information discovery effect and to the role of rating in the current financial regulation certification effect conversely the cds market does not seem to react significantly to rating warning outlook and review announcements furthermore we find evidence of a spillover effect only after a downgrade announcement our results show that the size of the spillover effect is influenced by economic and financial conditions of analyzed countries and that international bank flows between emu members represent an important transmission channel of the spillover effect

stock price reactions to the wall street journal s securities recommendations this paper examines the impact of the heard on the street hots column of the wall street journal on common stock prices the results of the study indicate that the hots column appears to have an impact on stock prices on the publication day however we also find a smaller but statistically significant impact on two days preceding the pub lication the significant abnormal returns on these days are associated with higher trading volume the reaction of stock prices is symmetric with respect to the buy and sell recom mendations and the impact of single company recommendations is greater than the im pact of the multi company recommendations i introduction the efficient market hypothesis assumes that security prices fully and instantaneously reflect all available information considerable evidence has been accumulated during the past decades in support of the hypothesis the acceptance of the hypothesis has raised questions about the economic value of professional investment advice if the market is efficient then the management of port folios based on these recommendations should not consistently outperform the market why then are investors still willing to pay for this information examples of the advice include low cost financial publications brokerage house rec ommendations and subscription financial newsletters that sell for hundreds of dollars recent studies argue that investment advisors can provide information to investors at a lower cost than the investors cost of information production millon and thakor 1985 develop a model that explains the existence of investment advisory agencies they argue that if the information of investment advisory agencies permits security analysts to share information about common uncertainties that affect the value of firms as a whole such as the return on the market portfolio then investment advisory agencies can produce information more cheaply than individual investors this model is consistent with the study of

the relation between sovereign credit rating revisions and economic growth abstract a country s economic growth exhibits a significant response to sovereign rating changes a one notch upgrade downgrade causes an increase decline of about 0 6 0 3 in re rated countries five year average annual growth rates the results hold after accounting for other determinants of economic growth and potential endogeneity problems and are robust to the use of quarterly data changes in country rating affect economic growth via the interest rate and capital flow channels narrower sovereign bond yield spreads and increased capital inflows are associated with upgrades which stimulate re rated countries economic performance and the converse holds for downgrades

the effect of lender identity on a borrowing firm s equity return previous research demonstrates that a firm s common stock price tends to fall when it issues new public securities by contrast commercial bank loans elicit significantly positive borrower returns this article investigates whether the lender s identity influences the market s reaction to a loan announcement although we find no significant difference between the market s response to bank and nonbank loans we do find that lenders with a higher credit rating are associated with larger abnormal borrower returns this evidence complements earlier findings that an auditor s or investment banker s perceived quality signals valuable information about firm value to uninformed market investors previous studies show that certain types of loan announcements generate significantly positive abnormal returns to the average borrower s equity 1 this finding contrasts with the negative equity returns generally associated with a corporation s issuance of public securities smith 1986 this difference in market reactions indicates that private and public securities are not perfect substitutes for the average firm in this sense lender identity defined as public versus private lender significantly impacts the borrower s abnormal equity return the standard theoretical explanation for this difference is that private lenders either obtain private information about the firm s value or they have the incentive and ability to monitor firm behavior more effectively than other outside monitors can although the empirical literature on private lending has evaluated primarily commercial bank loans and lines of credit these theoretical arguments apply equally to any type of private

moody s and s p ratings are they equivalent conservative ratings and split rated bond yields we examine the relative impact of moody s and s p ratings on bond yields and find that at issuance yields on split rated bonds with superior moody s ratings are about 8 basis points lower than yields on split rated bonds with superior s p ratings this suggests that investors differentiate between the two ratings and assign more weight to the ratings from moody s the more conservative rating agency moody s becomes more conservative after 1998 and the impact of a superior moody s rating becomes stronger furthermore the differential impact of the two ratings is more pronounced for the more opaque rule 144a issues

the impact of bond rating changes on corporate bond prices new evidence from the over the counter market abstract i study the information content of bond ratings changes using daily corporate bond data from trace abnormal bond returns over a two day event window that includes the downgrade upgrade are negative positive and statistically significant although the reaction to upgrades is economically small monthly abnormal bond returns around downgrades and upgrades are statistically significant but overstate the magnitude of the reaction relative to two day abnormal returns unlike the bond market the stock market reaction to upgrades is statistically insignificant evidence suggests that the differing inferences on the effect of upgrades in the two markets can be attributed to wealth transfer effects rather than relative market inefficiencies in the cross section the bond market response is stronger for rating changes that appear more surprising rating changes of lower rated firms and upgrades that move the firm from speculative grade to investment grade

costly information transmission in continuous time with implications for credit rating announcements abstract this paper formulates a continuous time information transmission model in which an altruistic sender privately observes a stochastic state variable and incurs a communication cost when she broadcasts a message we characterize the sender s optimal announcement strategy using an ordinary differential equation we prove the optimality of the sender s strategies using a martingale verification argument and show that the sender s optimal strategy involves sending discrete messages furthermore we apply the model to the timing decision of credit rating announcements and provide a framework to study various aspects of rating announcements such as the probability of rating reversals and the expected time before a rating change

the effect of a rating downgrade on outstanding commercial paper diamond 1991 argues that a firm s reputation determines whether it borrows directly or through an intermediary we test the diamond model by examining the quantity response of commercial paper issued by bank holding companies to a rating downgrade from 1986 to 1991 cumulative abnormal declines averaged 6 69 percent in the first two weeks after the downgrade and 11 05 percent in the subsequent 12 weeks in contrast to commercial paper issued by bank holding companies large cds issued by affiliated banks did not change significantly in the period around a downgrade suggesting that deposit insurance may have removed market discipline from the cd market the objective of this study is to test diamond s 1991 theory of corporate capital structure in which a firm s reputation determines whether it borrows directly or through an intermediary in diamond s model a firm without an established reputation will borrow through and be monitored by an intermediary by building a good reputation a firm may gain access to the nonintermediated markets such as the commercial paper market and consequently avoid the cost of monitoring in the process of maintaining its reputation a firm may eliminate the conflict of interest between borrowers and lenders about the choice of risk in investment decisions such firms have an incentive to maintain their reputation because the reputation itself has become a valuable asset that reduces borrowing costs in the model a firm that loses its reputation will find the cost of placing debt directly prohibitively expensive using event study methodology we test the diamond model by examining the quantity response of commercial paper cp to a rating downgrade of the issuing company we focus on ratings because firms that borrow in the cp market usually have high ratings in part these ratings reflect the firms reputation for selecting safe investments in the diamond framework if credit ratings proxy for reputation then a rating downgrade may be associated with a decline in the amount of outstanding cp this change in capital structure may occur relatively rapidly because outstanding cp typically has a

the informational role of bond analysts this study uses a large sample of sell side bond analysts reports to examine the properties of recommendations provided by bond analysts and the impact of these recommendations on bond securities first we document that the distribution of bond analysts buy hold and sell recommendations is skewed positively but less so than the distribution of equity analysts recommendations the positive skewness in bond analysts recommendations is greater for

the information content of municipal bond rating changes a note municipal bond rating changes have positive social value if they signal previously unavailable information on changes in municipal financial soundness weinstein 11 has found that rating changes for corporate bonds do not appear to contain relevant new information his finding is consistent with that of pinches and singleton 7 that stock price adjustments occurred several months prior to a corporate bond rating change rating agencies apparently respond to changes in corporate financial and operating conditions several months after the information is impounded in bond and stock prices 1 however as a result of institutional differences between corporate and municipal bond markets it is possible that rating changes for municipal bonds do convey new information this note examines the information content of municipal bond rating changes by evaluating municipal bond price adjustments during the period surrounding a rating change the joint hypothesis tested is that municipal bond rating changes convey information to investors which is relevant for assessing equilibrium values of the securities and that the municipal bond market is efficient so that valuation changes occur simultaneously with rating changes the following section examines the institutional setting of the municipal bond market in order to specify why information content of bond rating changes might be anticipated remaining sections of the paper describe sample selection derivation of test data findings and discussion

corporate bond ratings changes and economic instability evidence from the korean financial crisis abstract this study presents the first empirical analysis of the impact of bond ratings changes during periods of significant economic instability using the korean financial crisis as the experimental stimulus the study documents that changes in korean bond ratings during the financial crisis resulted in dramatically stronger changes in stock prices than ratings changes of identical magnitude announced either before or after the crisis

output spillovers from changes in sovereign credit ratings this research examines how a sovereign rating revision of one country influences the economic growth rates of other countries rating revisions have significant output spillover effects a one notch upgrade downgrade prompts on average a significant downward revision of about 0 03 0 07 in the consensus forecast of annual economic growth rates of other countries in the two month period after the event the spillovers are transmitted through direct and indirect trade and financial linkages between event and non event countries the evidence indicates that a predominance of differential common spillovers leads upgrades downgrades to produce adverse output effects for other countries

bond rating agencies and stock analysts who knows what when both bond rating agencies and stock analysts evaluate publicly traded companies and com municate their opinions to investors comparing the timeliness of each we find that granger causality flows both ways while most bond downgrades are preceded by declines in actual and forecast earnings both actual earnings and forecasts of future earnings tend to fall following downgrades although part of this post downgrade forecast revision can be attributed to negative news regarding actual earnings most appears to be reaction to the downgrade itself we find little change in actual earnings following upgrades analysts however tend to increase their forecasts of future earnings

an empirical analysis of strategic competition and firm values the case of r d competition abstract we operationalize a firm s competitive strategy through a new empirical measure and develop a framework for empirical analysis of the market value of strategic behavior using this framework we study announcement effects of r d spending the announcing firm s stock prices are positively influenced by a change in spending and negatively by our competitive strategy measure csm competitors stock prices are positively influenced by the interaction between the market s reaction to the announcing firm and the csm our results are consistent with positive effects of accommodating competition with strategic substitutes and nonpositive effects of tough competition with strategic complements

information effects in financial distress the case of seabrook station abstract in 1972 a group of electric utilities announced plans to construct seabrook station a nuclear generating facility in 1988 the lead partner in the venture public service company of new hampshire psnh filed for bankruptcy examination of the stock price effects of a variety of financial events preceding the bankruptcy filing shows that information about cash flows paid to psnh security holders affected the common stock prices of psnh and its seabrook partners whereas information about investment and operating cash flows had little or no effect

an analysis of value destruction in at t s acquisition of ncr abstract at t s 7 5 billion acquisition of ncr decreased the wealth of at t shareholders by between 3 9 billion and 6 5 billion and resulted in negative synergies of 1 3 to 3 0 billion we find that at t paid a documented 50 million and possibly as much as 500 million to satisfy pooling accounting thus boosting eps by roughly 17 but leaving cash flows unchanged we conclude that at t s decision to acquire ncr in what the market perceived as a value destroying transaction was related at least in part to the 1984 consent decree with the department of justice that led to the break up of at t

ratings hardwiring and asset prices this paper discusses the asset pricing implications of ratings hardwiring the latter is defined as the mechanical response of trading decisions to changes in ratings this issue is studied within a noisy rational expectations framework of asset pricing under asymmetric information in which traders specialize in different driving factors of asset payoffs and interact with others who mechanically link their asset supply to ratings we show that ratings hardwiring leads to predictable supply shocks and induces informed traders to overreact to new information thus creating a channel through which shocks are amplified and prices become less informative and more volatile

credit rating and debt crises we develop an equilibrium theory of credit rating in the presence of rollover risk by influencing rational creditors ratings affect sovereigns probability of default which in turn affects ratings our analysis reveals a pro cyclical impact of credit rating in equilibrium the presence of a rating agency increases default risk when it is high and decreases default risk when it is low

demand for health a generalised grossman model the demand for health and medical care is analysed within a generalised grossman type health investment model its underlying assumptions are shown to differ from those employed earlier in a manner which avoids some of the criticisms levelled at grossman s model the comparative static predictions of the generalised model are examined and it is demonstrated that most previous health investment models are derivable from it also the present model is applicable to a new wider range of problems thus increasing the scope of economic explanations of health behaviour

central bank independence and inflation corporatism partisanship and alternative indices of central bank independence a well developed theoretical literature suggests that central bank independence causes low inflation empirical work supporting this hypothesis is unsatisfactory however for two reasons statistical analysis has only recently begun to include control variables and important political variables that are related to inflation have not yet been included analysis has not yet undertaken a systematic comparison of alternative indices of central bank independence this paper addresses both weaknesses by testing the explanatory power of eight indices of central bank independence in a political economic model of inflation the results suggest that while support for the central bank independence hypothesis survives a relatively inclusive set of control variables support for the hypothesis is not independent of the particular index upon which analysis relies
