what policy adjustments in the eu ets truly affected the carbon prices abstract carbon market becomes increasingly popular as a cost effective instrument to mitigate co 2 emissions however its construction is a learning by doing process and needs consistent regulatory updates in order to deliver optimal effects this paper uses the event study method to assess the impacts of different policy adjustments on the eua returns in the european union emissions trading scheme eu ets since 2005 comparing to existing studies that focus on the impact of a single policy this paper provides a complementary reference on if and to what extent policy adjustments can impact the carbon prices by classifying all regulatory update events into six categories its key findings are as follows first aggregate impacts of total 50 events studied are low while impacts of events having underlying negative impacts are higher than those having underlying positive impacts second 24 events have significant impacts on eua returns and are coherent to their theoretical impacts except one event third events having negligible impact on eua returns are those that are announced not for the first time or those having no impact on co 2 quotas supply and demand finally there are different impact patterns some events have different impacts on short end and long end carbon prices

market power of local cable television franchises evidence from the effects of deregulation the 1989 cable act eliminated most price regulation of cable television operators including the right of municipalities to enforce price terms in franchise agreements deregulation was justified at least partially by the contention that competition from other entertainment media eliminated any market power of cable franchises we examine the value at sale of existing cable systems before and after deregulation assuming that this value represents the expected present value of future profits deregulation had the predicted negligible effect on profits in cities with significant broadcast competition however profits appear to have increased in areas where the competition from broadcast television was less severe we explore several explanations for this increase and conclude that significant market power is the most plausible explanation

is the stock market sticker shocked a study of market response to recent cafe regulations in the us in response to increasing environmental concerns to improve energy security and to conserve energy use the us government has proposed a new round of corporate average fuel economy cafe standards many studies have focused on how the cafe standard can be met by various automakers that have sales in the us market and the costs and benefits of the companies meeting the standard however the stock markets view on the impact of the standard on automakers profitability is largely absent we study the more recent episode of the cafe regulation in an effort to try to detect the market response using the standard event study method our empirical findings suggest that while the stock market had some responses to the regulation the large scale and systematic reaction to the regulation is absent in addition the market response pattern to the regulation appears to be tied to the individual company s compliance condition if there is any significant response at all

market response to banks granting lines of credit abstract prior research has shown and this paper confirms that when the market becomes aware a line of credit is granted the borrower s stock has a positive and significant reaction the borrower s reaction is used to identify the exact date the market becomes aware of the granting of the line of credit this date is used as a one day window to investigate whether the bank s stock also reacts this reaction will be most obvious with large lines of credit all lines of credit larger than us 1 billion granted during the years 1993 1996 are investigated the results show as predicted a positive and significant reaction by the bank s stock

additions to bank loan loss reserves good news or bad news abstract this paper examines the effects of citicorp s and succeeding banks loan loss reserve announcements in 1987 it was found that while the average effect on bank stock return portfolios was weak the effect on individual bank returns was heterogeneous tests were undertaken to determine which bank specific variables explained the latter result two significant variables were the size of a banks ldc debt exposure and its position in ldc rescheduling committees

effects of the 1970 bank holding company act evidence from capital markets this study measures the effects of the 1970 amendment to the bank holding company bhc act on the profitability and risk of bhcs using capital market data differences in abnormal returns and risk among three portfolios of bank shares which differ in their regulatory status are examined in various periods preceding and following the enactment no significant differences in performance and no change in the relative risk of any pair of portfolios were observed thus the null hypothesis that the nonbank expansion provisions of the 1970 amendment had no effect on bhcs risk and profitability cannot be rejected the growth of bank holding companies and their expansion into nonbank activities following the 1970 amendment to the bank holding company bhc act of 1956 produced striking structural changes in the banking industry the nonbank expansion provisions of the statute triggered a continuing debate about the costs and benefits of these provisions black miller and posner 2 consider the amendment to be an important innovation that can increase the efficiency and hence the profitability of financial intermediaries other writers however suggest that nonbank activities of bank holding companies may increase the risk of bank failure thereby increasing the regulatory involvement silverberg 14 orgler and wolkowitz 13 and mayne 10 2 this study analyzes the effects of the 1970 amendment to the bank holding company act on the profitability and riskiness of bank holding companies capital market data are used to measure risk and return fama 6

the wealth effect and diamond risk structure of financial regulation the objective of this article was to evaluate the effect of announcements of financial regulation on risk and return in the vietnamese equity market the techniques used for the purpose of analysing risk and return include event study and non parametric tests as well as asset pricing models supplemented with interaction variables and a variety of arch like specifications such as garch tarch egarch and parch we find evidence for the wealth effect the presence of delayed response and a risk shifting behaviour in the form of diamond risk structure our results show that abnormal returns are present around the announcements of operating rules and other stock market regulations abnormal returns can also be obtained after considering legal documents such as circulars and decisions

accounting for retail land sales analysis of a mandated change abstract this study assesses the stock market s reaction to a series of events leading up to a mandated change in accounting for retail land sales evidence is found to support the conclusion that the market reacted to some of these events in a manner consistent with the effects of the accounting change on debt annagement contracts a distinctive aspect of the analysis is the efficient use of security returns data to detect market reactions and to derive empirical distributions of test statistics employed the analysis is extended by a model for grouping regression equations known as seemingly unrelated regressions however the gains from this extension are modest

measuring the effects of regulation with stock price data this article examines the usefulness of stock returns in measuring the effects of regulation when the dates on which market expectations change are not known and standard sources e g the wall street journal are used to choose announcement dates twenty major changes in regulatory constraint since 1887 are considered tests using either monthly or daily data are found to have surprisingly little ability to detect the effects of regulation the evidence shows that formal regulatory announcements are generally anticipated in cases where it is unclear when expectations change

equal employment opportunity law and firm profitability based on a sample of 260 cases reported in the wall street journal between 1964 and 1986 this study finds that the equity value of firms charged with violating equal employment opportunity eeo laws fell at the time that a suit decision or settlement was announced most dramatically the value of firms involved in class action suits fell 15 6 percent on average around the time of the suit further the average loss to shareholders exceeds the amount firms are required to spend to settle the case this may be due to the expected costs of changing employment practices or to the information about the firm s management that is revealed by the case a staggering number of statutes amendments and court decisions regulating equal opportunity in employment have been passed during the past 25 years firms found guilty of violations of equal employment opportunity laws have been required to pay millions of dollars in back pay and to alter their employment practices to comply with the laws this study measures the costs to firms resulting from government and private lawsuits and the further costs of losing those suits i address this question by examining changes in the market value of the equity of firms at the time a lawsuit is filed for a violation of an equal employment opportunity eeo law and at the time a decision of guilty or a settlement

the wealth effects of deregulation of canadian financial institutions abstract canada like other industrial countries recently introduced various financial reforms to remove the barriers separating the operations and ownership of banks from non bank financial institutions this study analyzes the wealth effects of the reforms on the banks and non bank financial institutions and the changes in their systematic risk resulting from financial deregulation over the period 1984 to 1991 the results indicate that while there was a significant cumulative gain for the insurance industry unlike a number of u s studies there was no evidence of wealth transfer among the institutions during the period of deregulation of the canadian financial system additional tests indicate that although the regulatory changes did not have a significant effect on the risk of the banks the systematic risk of the non bank financial institutions increased significantly during the period of regulatory reforms

time consistent collection of optimal seigniorage a unifying framework this paper reviews the existing literature on the time consistency problem of seigniorage collection when monetary policy is determined by optimal taxation considerations it develops a unifying accounting framework and suggests a general measure for seigniorage which encompasses the standard measures employed in the literature in addition the ex ante optimal solution to the optimal taxation problem is derived and interpreted in relation to the ramsey principle we show that the different recommendations of the public finance literature i e the friedman rule of optimal deflation moderately positive inflation and seigniorage maximizing inflation are specific solutions to the optimal taxation problem the paper continues with a formal illustration of the time consistency problem of the ex ante optimal policy and the characterization of the time consistent solution under discretion as possible solutions to the time consistency problem we consider reputational forces institutional reforms that establish central bank independence and specific ways of asset and debt management in particular it is formally shown that a modified version of the asset and debt management scheme suggested by persson persson and svensson is not only necessary but also sufficient for optimality although this did not hold in their model

the competitive effects of resale price maintenance the competitive effects of resale price maintenance rpm are theoretically diverse rpm can cause allocation distortions or promote productive efficiencies in the distribution process moreover extant cross sectional empirical evidence is incapable of distinguishing among the potentially disparate effects of rpm this paper conducts hypothesis tests of the alternative theories of rpm the empirical framework relates estimates of the effects of rpm for a cross section of observations to necessary conditions of the alternative models this analysis indicates that rpm is used both to foster cartels and promote efficiencies in the distribution process this result is consistent with the growing body of case study analysis that suggests that rpm is used for a variety of reasons this result also questions the current per se illegal status of rpm in the antitrust laws evidence is also provided concerning the strategic interaction between manufacturers and dealers in the distribution process and the use of financial data in analyzing propositions in industrial organization

a new test of the relationship between regulatory change in financial markets and the stability of beta risk of depository institutions the us economy experienced major regulatory changes in the banking and finance industry with the passage of five major acts over the period 1980 to 1991 this has generated an extensive literature investigating the effects of these changes on the us banking industry in particular this body of research has examined the share market reaction to regulatory changes as well as their impact on the risk return market value and profitability of banking industry stocks generally it has been found that the regulatory changes have had a substantial impact although the effect has not been uniform across all depository institutions this paper extends this literature by analysing the stability of a sample of eighteen us banking industry stock betas across five periods a pre regulatory change period a monetary experiment period a deregulation period a reregulation period and a post regulatory change period based on an analysis of weekly returns we find that the level of bank risk has increased further we also find a tendency towards greater beta instability in both the monetary experiment and deregulation samples the degree of beta instability is lowest in the pre regulatory change and post regulatory change samples overall the monetary experiment and regulatory change coincided with an increased tendency towards beta instability we also compare our results to a randomly selected control sample of non banks and find some more general effects of regulatory change on individual stock betas

litigation and the value of tobacco companies this study determines how the recent wave of litigation affected returns and systematic risk in the tobacco industry we test for changes in stock prices coinciding with litigation announcements using a difference in difference event study methodology unfavorable information concerning litigation reduced tobacco returns we find a decline in systematic risk as traditionally measured by the covariance between industry returns and returns to a diversified efficient portfolio this decline may imply a substantial decline in the cost of equity capital of at least 2 2 after the period of litigation which we attribute to common cost shocks experienced by the companies participating in the master settlement agreement combined with the oligopolistic structure of the industry

market expectations of the effects of the tax reform act of 1986 on banking organizations abstract this study investigates market expectations regarding the effect of the tax reform act of 1986 on the banking industry the evidence shows that overall the tax reform did not adversely affect the stocks of banking institutions the findings suggest that overall banking organizations were expected to largely mitigate any negative effects of the tax reform on their cash flow by rebalancing and or repricing their portfolios of assets and liabilities the most significant provision of the new act was the limitation on foreign tax credits interestingly the markets did not expect any adverse valuation effects from the recapture of loan loss reserves or the elimination of the interest deductibility for carrying tax exempt securities

safety net losses from abandoning glass steagall restrictions this paper evaluates the redistribution of gains surrounding regulatory relaxations in 1996 and 1997 and ultimate passage of the financial services modernization act fsma of 1999 gains in financial institution stocks may come from projected increases in efficiency increases in the bargaining power of financial institutions or greater access to the federal safety net for customers seeking improved access to capital markets gains in efficiency should result in increased benefits but increases in bank bargaining power could increase funding costs and or decrease capital market access customers may also lose as taxpayers who support the federal safety net this paper finds evidence of potential taxpayer losses and increased bank bargaining power especially vis a vis credit constrained customers for whom safety net subsidies are unlikely to be shifted forward the stock prices of credit constrained customers declined during fsma event windows and in event windows associated with regulatory relaxations

george stigler s contribution to the economic analysis of regulation george stigler changed the way economists analyze government regulation this enormous legacy is essentially embodied in two articles his 1962 analysis of electricity rates with claire friedland and his 1971 theoretical piece there were to be sure precursors and successors in his own work but none of them so profoundly affected the course of intellectual inquiry as these two the importance of both articles rests more i believe with the questions each posed than with the answers even by the standards of the day neither piece evinced the sort of technical sophistication that the profession has come to admire neither produced conclusions that were impervious to all serious subsequent challenges but both produced insights that have altered the course of research in the area to this day to understand stigler s contribution it is best to proceed chronologically and to begin with the state of the field around 1962 there is room here only for caricature rather than extensive survey however i think it is fair to say that the field derived its main energy from the normative economics of marginal cost pricing the proper role of government was to correct the private market failures that prevented attainment of marginal cost pricing applied economic analysis of regulation was then largely descriptive and its main tendency was to show how the regulatory institutions constrained departures from marginal cost pricing monopoly was viewed as the main barrier to marginal cost pricing and the natural monopoly occupied center stage in the economics of regulation the prime examples of natural monopoly were sup1 man made monopolies were the main subject matter of industrial organization stigler s profound influence on this field is summarized by harold demsetz s article in this issue

the market valuation effects of the financial institutions reform recovery and enforcement act of 1989 abstract this paper evaluates the stock market effects of events leading to the passage of the financial institutions reforms recovery and enforcement act of 1989 the evidence suggests that the signing of the act by president bush produced positive abnormal returns for both banks and s ls and that the addition of tougher capital standards produced positive returns for s ls in addition the act increased the risk of both banks and s ls

analysis of the effectiveness of the first european pollutant emission register eper abstract the aim of this paper is to examine the effectiveness of the first european pollution emissions register eper a regulatory instrument based on the publication of the environmental performance of firms exceeding specified pollution limits the multivariate regression model mvrm is applied to capture the disciplinary effect of the eper so we first perform an analysis to determine whether the publication of the eper has a negative effect on the market value of the listed firms secondly we consider the possibility of the publication of the eper affecting the market value of firms which could be included in the eper but are not because their emissions do not exceed the specified pollution limits finally we prepare an index to compare the environmental results of the firms and analyse whether the consequences of publishing the eper are worse for firms with high relative pollution records

the impact of culture on the strategy of multinational enterprises does national origin affect ownership decisions this paper tests the proposition that national origin affects the strategies of multinational enterprises by looking at the determinants of the choice they make between entering the united states through partially versus wholly owned subsidiaries we pool entries into the united states made by firms based in two countries japan and finland which differ both in their cultural characteristics and in their cultural distance to the united states after carefully controlling for the known firm and industry level determinants of subsidiary ownership strategies we find that cultural distance between the home base of the investor and the target country or perhaps political risk exerts a powerful influence on ownership of subsidiaries but cultural characteristics of the home base do not

the effects of the nlra on stockholder wealth in the 1930s whereas most recent research examining the effects of the nlra on labor management relations has focused on the impact of specific provisions of the law this study provides an estimate of the impact of the passage of the nlra on 75 firms that were at great risk of being unionized in the 1930s taking changes in shareholder wealth as a measure of the shift in the balance of power caused by the nlra the authors find that the passage of the nlra caused a statistically and economically significant decline in shareholder wealth for the sampled firms specifically by april 1937 stockholder wealth in the firms was 15 9 lower than would have been expected had the nlra not been enacted t he impact of public policy on the balance of power between labor and management has always been a fundamental topic in industrial relations recent changes in many labor management relationships have renewed interest in the influence of public policy on labor relations and raised questions of how modifications in these policies might alter the behavior of the parties according to delaney lewin and sockell 1985 the empirical research on this topic has largely concentrated on specific provisions of the wagner act such as election procedures and regulation of employer unfair labor practices for example getman gold

the impact of fraudulent false information on equity values there are two types of stock price manipulation examined in the theoretical literature 1 insider trading which involves private information that is true and 2 the public spreading of fraudulent false information while there is a large empirical literature on insider trading this is the first empirical article to examine the impact of false fraudulent public information on stock prices and trading volume we find that such false information even after being denied by a credible source such as the sec generates both abnormal returns and abnormal trading volume we also find that the effects of the false information on security returns and volume can be persistent for at least 2 weeks in addition we show that perpetrators of false news attacks can make potentially large profits from such market manipulations

state regulation of takeovers and shareholder wealth the case of new york s 1985 takeover statutes past studies of takeover regulations have found that such rules increase the premiums paid to the shareholders of successfully acquired targets jarrell and bradley argue that these higher premiums harm shareholders by discouraging takeover activity and protecting inefficient managers bebchuk argues that the higher premiums do not significantly reduce the number of takeovers so that shareholders benefit on average from the higher premiums paid in successful acquisitions this article uses the event study method to measure the net effect of two takeover statutes passed by the new york state legislature in 1985 the results support the conclusion of jarrell and bradley that despite the higher premiums paid to successfully acquired target shareholders ex post these laws on average harm shareholders ex ante

antitrust policy and mergers the wealth effect of supreme court decisions many believe that antitrust policy has had a dramatic impact on merger strategies in the united states for this to be true enforcement of antitrust laws must affect a wide range of firms not just those firms whose mergers are contested this study tests whether or not firms engaged in uncontested mergers are affected by antitrust enforcement as signalled by supreme court decisions using event study methodology we find that antitrust policy against mergers was binding during the 1960s and 1970s as it ulowered the value of targets in ucontested ongoing mergers

market reaction to the formation of export trading companies by american banks the stock and bond market reactions to american banks announcements of their intentions to form export trading companies are investigated the results are robust to various return generating model specifications and are consistent with the view that the markets do not believe that u s bank export trading companies will be successful

the gains from takeover deregulation evidence from the end of interstate banking restrictions this paper uses interstate banking deregulation to explore the benefits of takeover deregulation and how these benefits are distributed across different firms we find large and significant abnormal returns around the interstate banking and branching efficiency act of 1994 which imply it created 85 billion of value in the banking industry consistent with an active market for corporate control allowing beneficial consolidation and providing needed discipline there is a strong negative relationship between banks abnormal returns and their prior performance consistent with managerial entrenchment limiting takeover discipline banks with higher insider ownership lower outside block ownership and or less independent boards have lower abnormal returns imagine an economy in which strict regulation has prohibited all takeover activity and the governing body suddenly announces that the restrictions on mergers and acquisitions will be eliminated in one year the capital market response to this announcement would establish the aggregate value added from an active corporate control market and differences between individual firms stock price reactions would reveal which firms benefit most from unrestricted consolidation and takeover discipline in some ways this hypothetical situation became reality for the u s banking industry in 1994 when congress wrote and passed the interstate banking and branching efficiency act ibbea this legislation liberalized the bank takeover market by eliminating the various state laws restricting bank mergers across state lines the ibbea was widely expected to accelerate the consolidation already occurring within the banking industry see for example american banker 10 11 94 a more active takeover market should increase firm values in at least two ways first unrestricted consolidation would allow firms to better utilize

are more innovative firms less vulnerable to new environmental regulation compliance with pollution limits and standards requires firms to implement adaptation processes that are not only costly themselves but also affect future profits in as much as they modify production systems and methods this paper attempts to respond to the question of how technological knowledge moderates the effect that the implementation of a new environmental regulation has on the results of affected firms the regulation selected for this study is the integrated pollution prevention and control act ippc a multivariate regression model mvrm has been applied to the regulatory event the most important implication of this paper is that technological knowledge prepares a firm for adapting to a greater environmental demand such as may be derived from a new regulation

stock market reactions to the depository institutions deregulation and monetary control act of 1980 abstract this paper evaluates the effects of events leading to the passage of the depository institutions deregulation and monetary control act of 1980 the evidence suggests that the initial proposal of the act by then president carter and the final passage of the act by the house of representatives produced positive abnormal returns to stockholders of large commercial banks stockholders of small commercial banks and small savings and loans on the other hand generally experienced negative abnormal returns furthermore when hopes of passage of the act faced significant negative positive abnormal returns were experienced by stockholders of large small commercial banks

an examination of the impact of the garn st germain depository institutions act of 1982 on commercial banks and savings and loans this paper evaluates the effects of events leading to the passage of the garn st germain depository institutions act of 1982 the evidence suggests that the call for reform by president reagan s housing commission and the senate passage of the bill produced positive abnormal returns to stockholders of large savings and loans and commercial banks stockholders of small s ls and banks on the other hand generally experienced negative abnormal returns furthermore when hopes of passage of the act faded significant negative positive abnormal returns were experienced by stockholders of large small s ls and banks this study examines the impact of the passage of the garn st germain depository institutions gsgdi act of 1982 on commercial bank and savings and loan stockholder returns the gsgdi act represents one of two major revisions of the financial system over the last twenty years the other being the depository institutions deregulation and monetary control act of 19801 the proposal for such a change reflected the growing inadequacy of the regulatory structure of financial institutions to adapt to rapid changes in technology shifting consumer demands for financial services and extremely volatile interest rates efforts to reform the financial system resulted in passage of the gsgdi act of 1982 which included provisions seeking to improve both the implementation of monetary policy and the degree of equity in the regulation of financial institutions such improvements were intended to reduce the operational and financial risk of financial institutions a central issue in the economics of regulation is whether regulatory actions benefit the economic agents they are intended to benefit a large body of literature exists which examines the economic effects of regulation much of this literature has utilized the concepts and methods of welfare economics to assess the extent

the wealth effects of the risk based capital requirement in banking the evidence from the capital market abstract the imposition of risk based capital requirements has been advocated by some regulatory authorities as a means of mitigating the incentive problems created by fixed premium deposit insurance however their imposition also constitutes a requirement to maintain an exogenously influenced capital structure which may adversely affect the values of the firms involved this paper examines the wealth effects of the announcement of the basle committee s intention to impose across international boundaries a pre determined minimum level of risk adjusted capital we find that in general the equity values of a sample of large publicly traded banks decrease at the time of the announcement further those banks with capital levels which are deficient relative to the mandated levels suffer the largest relative losses

on the relation between reschedulings and bank value the effect of developing country loan reschedulings on large u s banks is investigated using an event study methodology the major finding concerns the evolving nature of the impact of loan reschedulings during 1978 80 reschedulings had a positive effect on bank returns in contrast to the negative impact found for the 1981 83 period an explanation for these results is provided by a model of the rescheduling process that recognizes the noncompetitive aspects of rescheduling negotiation copyright 1989 by american economic association

an analysis of the impact of deposit rate ceilings on the market values of thrift institutions this paper examines the impact of changes in deposit interest rate regulations on the common stock values of savings and loan institutions the analysis indicates that stockholder owned savings and loans s l s have experienced statistically significant declines in equity market values at the announcement of the removal of ceilings on certain consumer small saver certificate accounts and the introduction of short term variable rate money market certificates we find the evidence to be consistent with the hypothesis that s l s have earned economic rents from restrictions on interest rates paid to small saver accounts and that relaxation of interest rate ceilings has reduced these rents a central issue in the economics of regulation is whether regulators behave in a way that primarily benefits the economic agents whose actions they are supposed to regulate the proposition that regulation is demanded and acquired by the regulated and that regulations are designed and administered primarily for their benefit was originally put forth by stigler 19 and has come to be known as the capture theory of regulation an alternative view is that regulators adopt policies which serve some other perhaps public or possibly the regulators own interest and that administration of these policies does not benefit the regulated entities this paper examines the regulation of savings and loan associations deposit interest rates and reports evidence pertaining to the impact of the administration of regulation regulation of interest rates paid to depositors in federally insured savings and loan associations began in 1966 since that time several changes in the maximum allowed interest rates deposit rate ceilings have been made these changes present an opportunity to observe the impact of one form of regulatory action on savings and loan institutions deposit rate regulation has been the subject of extensive previous research the empirical investigations have focused primarily on two issues 1 the allocational efficiency and wealth redistribution effects of rate ceilings and 2 the impact of deposit rate ceilings on the flow of funds into the residential

auditor reputation the impact of critical reports issued by government inspectors in recent years u k department of trade investigations into the affairs of a specific company have sometimes been critical of the work done by its auditors and reporting accountants this article assesses the impact of this criticism on the auditor s reputation in particular it examines the stock price performance of the auditor s listed clients the results show a small wealth loss for the audit clients the article also examines the impact of the department of trade criticism on an audit firm s number of listed clients and its future audit fees compared to a control group the criticized auditors appear to suffer a small loss in market share based on number of listed clients and on audit fees the evidence suggests that criticized auditors incurred economic losses from the damage to their reputations this is consistent with models of reputation advanced in the industrial organization literature

does the japanese governance system enhance shareholder wealth evidence from the stock price effects of top management turnover this article examines the stock price effects of top management turnover announcements for 432 japanese corporations from 1985 to 1990 we find that these announcements are associated with significantly positive abnormal returns the returns are greater when turnover is forced than when turnover represents normal succession the stock price effects are also significantly positive when turnover is forced and the successor is appointed from outside the firm we find that large shareholders play an important role during outside succession this evidence suggests that the disciplinary decisions of japanese governance mechanisms are consistent with shareholder wealth maximization article published by oxford university press on behalf of the society for financial studies in its journal the review of financial studies

japan s shift from process to product patents in the pharmaceutical industry an event study of the impact on japanese firms in 1975 japan expanded the scope of its patent law by introducing product patents for newly developed chemical and pharmaceutical products we use rate of return data from the tokyo stock exchange for japanese pharmaceutical companies to examine the impact of the change in the patent law our empirical findings indicate that the passage of the new patent law induced an excess return of approximately 26 percent to a portfolio of large pharmaceutical companies companies with r d programs specializing in new product development experienced large gains while companies with r d programs specializing in imitative process patents experienced no gains

using stock price data to measure the effects of regulation the interstate commerce act and the railroad industry this article usesjinancial data to measure the effects of the passage of the interstate commerce act of 1887 and subsequent legislative and judicial developments on firms in the railroad industry the results indicate that the interstate commerce act had a significant positive impact on railroad stock prices and that court decisions in the 1890s which severely restricted the powers of the interstate commerce commission caused negative stock price reactions thesefindings offer support for the revisionist view of regulatory history according to which the railroads welcomed regulation as a means offacilitating the enforcement of cartel like agreements

ceba of 1987 and the security returns and market risk of savings and loan institutions a note abstract this article examines the market reaction to announcements leading to the eventual passage of the competitive equality banking act ceba of 1987 using portfolios of savings and loans negative announcement effects of the ceba legislation are observed for well capitalized savings and loans and positive announcement effects are observed for less capitalized savings and loans the evidence also indicates that the market risk for the less capitalized savings and loans decreased following the passage of the ceba legislation

prime rate changes is there an advantage in being first this article analyzes the impact of prime rate changes on stock prices of prime rate change initiating banks relative to noninitiating banks the prime rate as a sticky price is analyzed and the potential directions and sizes of information effects are discussed and empirically examined it is found that prime rate increases generally convey bad news about the initiating banks prime rate decreases in contrast have weakly positive effects on the initiating banks prime rate change announcements are also found to have some effect on banks other than the initiating bank implying that contagion effects exist copyright 1993 by university of chicago press

election returns as a signal of changing regulatory climate abstract this paper considers the effects of changes in regulatory climate on the expected future profitability of regulated electric utilities previous researchers addressing issues relating to regulatory environment have examined the determinants of investor perceptions of regulatory climate the effect that the method of commissioner selection in particular has on regulatory climate and the effects of regulatory climate on the cost of capital to the regulated firm this paper seeks to ascertain the importance of regulatory climate by examining the stock market performance of regulated electric utilities at the time of an unanticipated change in regulatory environment these results indicate that in those states in which the change in regulatory climate was most clearly unanticipated an adverse change in the regulatory environment did result in negative abnormal returns to utilities operating in those states thereby indicating a reduction in the expected future profitability of the regulated firms in addition our results provide support for the proposition that the firm s systematic risk is lower when enforcement of regulation is more stringent

on the efficiency of least squares regression with security abnormal returns as the dependent variable monte carlo procedures are used to compare the finite sample performance of several estimators that may be used in cross sectional regressions with security abnormal returns as the dependent variable alternative models of event induced increases in stock return variance are examined for the event clustering scenario event clustering implies crosssectional correlation and heteroskedasticity in market model prediction errors violating one of the fundamental ordinary least squares ols assumptions i i d disturbances nonetheless provided that the conditions for asymptotic validity derived by greenwald 1983 are met the ols estimator is well specified in finite samples further for sufficiently large cross sections there is no advantage to several other more complex estimators

what can regulators regulate the case of bank entry previous researchers have claimed that the banking acts of 1933 and 1935 reduced the annual rate of entry of new commercial banks by as much as 50 percent between 1936 and 1962 in contrast the authors find that this legislation did not reduce bank entry rates previous studies did not account for legislative changes that reduced restrictions over branch banking and stimulated growth in the number of branches in about half the states during the 1936 62 period after accounting for these changes in branching laws it becomes clear that entry of new banks was depressed by growth in branch banks not by restrictive federal regulations copyright 1992 by ohio state university press

the differential impact of two significant court decisions concerning banking consolidation abstract two 1981 court rulings effectively removed the possibility that federal regulatory agencies could apply the theory of probable future competition to block future bank mergers and takeovers results show that the impact of this regulatory change which occured without any contemporaneous public press coverage led to a significant decline in the wealth of shareholders of banks that had been active acquirers these findings are consistent with mueller s size maximization and roll s hubris hypothese

value event studies this paper discusses appropriate methodology for measuring the effect of an event on the value of a firm s equity th e key points are 1 cumulative abnormal returns do not measure the effect of an event on firm value if there are dividends during the event window 2 it is generally appropriate to use pre event parameters of the return generating process even if the event alters the parameters during the event window and 3 controlling for fact ors other than the return on the market portfolio improves the power of the estimation the formula for the effect of an event on the value of a firm when there are dividends during the event window is developed a nd applied to a study of the effect of the bhopal disaster on the value of union carbide copyright 1992 by mit press

the reaction of bank stock prices to news of derivatives losses by corporate clients abstract from march through may of 1994 several large nonfinancial firms announced millions of dollars in losses from derivatives deals especially those arranged by bankers trust accompanying these announcements and related news stories were allegations that bankers trust had either misrepresented lied or deceived its clients using sur methods we investigate how these announcements affected bankers trust and three portfolios of banks dealers nondealers and nonusers our results indicate significant cumulative abnormal returns of 12 14 bankers trust 5 56 13 dealer banks and 2 45 32 nondealer user banks the evidence suggests an intra industry information transfer effect consistent with rational pricing the replacement cost of derivative contracts is an important factor in explaining the variation in abnormal returns across banks

estimating the structure of market reaction to news information events and lumber futures prices we develop a new event study technique the distributional event response model derm appropriate to relatively slowly evolving information events we apply the model to twelve years of daily lumber futures prices and analyze the effects of three different types of information releases a monthly housing starts estimates b aperiodic administrative and judicial announcements about u s canada trade disputes and c novel and unprecedented court decisions related to the endangered species act esa the information releases are different in ways that predict their relative speeds of impoundment in prices we find that housing start events are absorbed more quickly than trade events which are absorbed more quickly than esa events

the brazilian default announcement and the contagion effect hypothesis abstract in this paper we use stocl market data to test several hypotheses regarding possible investor reaction to the february 20 1987 brazilian default both the traditional event study approach and a generalized least squares regression using brazilian exposure as an explanatory variable for abnormal returns are used a sample of 46 bank holding companies all listed on the new york or american srock exchanges is divided into groups of no low and high brazilian exposure we find that the initial stock market reaction to the default represents a rational investor response to new bank specific information however the stock market reaction also reveals that not all relevant information was contained in the disclosure announcement further we find some evidence of a contagion effect related to size

using information diffusion models to estimate the impacts of regulatory events on publicly traded firms abstract analysis and evaluation of regulatory actions require inexpensive and timely information about resultant costs and benefits this paper extends the traditional event study methodology for assessing the impact of regulatory actions on the value of publicly traded firms we use diffusion theory to construct several models of how markets adjust to regulatory events ex ante preference for a particular model is based on prior knowledge about the characteristics of the regulatory event and information diffusion patterns we demonstrate the use of the methodology by applying it to an analysis of the impacts of a regulatory action taken to protect the northern spotted owl

government revenue from money creation with government and private money abstract for a stationary state we show that if the government is as efficient as a competitive banking industry in producing money then the substitution of private for government money does not alter the revenue from money creation or the present value maximizing holding cost of money if households and non banking firms hold both government and private money then maximum present value requires that the reserve ratio maximize the monetary base and that the base nominal interest elasticity equal minus one with perfect foresight zero money balances and zero revenue from money creation is the only time consistent revenue maximizing solution

didmca and bank market risk theory and evidence abstract this paper examines the theoretical and empirical consequences of the depository institutions deregulation and monetary control act of 1980 on the market risk of the us banking industry we survey several theoretical arguments linking deregulation of deposit interest rates to market based measures of bank risk capital market data for a sample of large commercial bank holding companies provides evidence that deregulation has accompanied increases in both systematic and nonsystematic measures of bank risk

standard errors in event studies even if true abnormal returns are uncorrelated estimated abnormal returns are not this paper presents a simple formula for the variance of estimated cumulative abnormal re turns both returns and dummy variable procedures for estimating the standard error correctly taking account of both intertemporal and contemporaneous correlation of esti mated residuals are discussed they are then applied to an event study of post merger performance it is shown that ignoring either the intertemporal or contemporaneous correlation of residuals can result in significant underestimates of standard errors

does the japanese stock market price bank risk evidence from financial firm failures the ability of the japanese stock market to appropriately price the riskiness of japanese financial firms has been frequently questioned particularly in light of japan s widespread financial distress in recent years and poor disclosure requirements this paper examines the response in equity returns of japanese banks to the failure of four commercial banks and two securities firms between 1995 and 1998 using event study methodology the analysis finds that share prices of surviving banks on the whole responded unfavorably to the failures and that financially weaker survivors were more adversely affected this suggests that despite the distress and alleged opaqueness bank shareholders were able to use available indicators of financial condition both to incorporate new information quickly into stock prices and to differentiate among banks

security price reactions around corporate spin off announcements abstract we examine security price reactions around the announcements of 123 voluntary spin offs by 116 firms between 1963 and 1981 involving a pro rata distribution of the common stock of a subsidiary to the stockholders of the parent firm the median spin off in the sample is 6 6 of the original equity value and is associated with an abnormal return of 7 0 from 50 days prior to the announcement through completion of the spin off no evidence is found to indicate the gains to stockholders represent wealth transfers from senior securityholders over the entire event period we find positive gains for firms engaging in spin offs to facilitate mergers or to separate diverse operating units but negative returns to firms responding to legal and or regulatory difficulties in the two day interval surrounding the first press announcement we find positive average excess returns for all groups

the incidence of regulatory rents in the motor carrier industry this article focuses on two questions in the debate over motor carrier regulation first did regulation create eliminate or have no effect on monopoly rents in the trucking industry second ifthere were rents what was their incidence were they received by owners oftrucking firms dissipated through higher costs or captured by the teamsters union data on share price responses to deregulation announcements reveal declines in expected profits of 8 19 of totalfirm value this suggests that regulation created monopoly profits and indicates that at least some of these rents accrued to owners of trucking firms firms responses to regulatory change are modelled as functions of company s operating characteristics and measures of unionization operating efficiency and service characteristics are shown to affect the impact of deregulation on share values

union effects on productivity profits and growth has the long run arrived this article interprets literature examining union effects on economic performance production function studies indicate small overall union impacts on productivity positive effects where they exist appear to result from management response to decreased profit expectations and from a natural selection process lower profitability among unionized firms is well established more interesting is the possibility that unions appropriate quasi rents deriving from long lived tangible and intangible capital the connection between unions investment behavior and productivity growth emerges as a particularly fruitful line of empirical inquiry although it does not encourage a sanguine view of unionism s long run impact

debt equity swaps regulation k and bank stock returns abstract since the early 1980s the financial health of several highly levered ldcs has become increasingly precarious their financial problems in turn imply potentially serious financial problems for their creditors foremost among whom are some of the largest banks in the american financial system in order to relieve some of the pressure on the lending firms the board of governors has recently amended regulation k which provides guidelines for international banking operations to allow for unrestricted investment in foreign nationalized firms through the mechanism of the debt equity swap this paper examines the capital market reaction to the regulatory change and we find that 1 investors on average viewed the change as a wealth increasing event 2 the magnitude of the market reaction was significant and positively related to the level of foreign lending exposure and 3 among ldc lenders the capital market reaction differed significantly between money center and non money center banks

the rise and fall of railtrack plc an event study forming railtrack was a key part of the privatization of british rail br railtrack took over the ownership of br s fixed infrastructure in april 1994 and its parent company the railtrack group was floated in may 1996 on the london stock exchange lse despite the group posting some excellent financial results in the early years railtrack s record on infrastructure improvement and safety was frequently criticized this apparent inconsistency between shareholder interests and public service obligations culminated in railtrack being placed in administration in october 2001 in view of this apparent inconsistency and the high court claim for additional compensation brought against the government by a group of 49 000 small investors the reaction of the stock market to 19 key events is modelled among other things we find when railtrack announced after the fatal derailment of a high speed train near the hertfordshire town of hatfield that there would be a 6 month programme of emergency track repairs t

do epa defendants prefer republicans evidence from the 2000 election i introduction there is an extensive body of literature documenting the effects of political interference in bureaucratic agencies much of this deals with the enforcement of antitrust disputes as mediated by the federal trade commission a corresponding literature on the political control of the environmental bureaucracy does not exist however there is a perception that the aggressiveness of environmental protection agency epa enforcement could vary from one administration to the next 1 the present article aims to subject these anecdotal impressions to empirical tests it uses the change in the price of publicly quoted companies that have civil judicial litigation outstanding with the epa when a political event takes place such as a presidential election to assess the market s reaction to this event ii literature review the biggest problem in doing empirical studies of the effect of political and legislative changes on stock market valuations is the fact that these changes happen slowly over a period of months or years given the assumption of efficient markets stock markets should immediately reflect all available information including the possibility of political changes this is the reason why studies of the effect of legislation and political change on market valuations have generally found insignificant results as in binder 1985 cutler 1988 downs and tehranian 1988 and graddy et al 1992 2 this article uses a better measure of the probability of a political event the measure of the probability of the outcome of an election is obtained from the iowa electronic market iem only herron et al 1999 and knight forthcoming have used this data source for similar purpose before 3 the iem is a set of continuous double auction markets operated by the university of iowa henry b tippie school of business most of the existing literature in this field has used opinion poll data such as brander 1991 the disadvantages of this are well known they are usually conducted over several days and so do not represent the probability of the election of a candidate on a single day they do not represent probabilities of election but rather expected vote shares they are not usually released daily and finally they have wide margins of error especially long before an election when many people have not yet made up their minds who to support herron et al 1999 pp 58 59 these are also some of the reasons that economists are generally skeptical of surveys preferring to rely instead on revealed preferences the only other possibility is the use of bookmaker s odds as used by roberts 1990b this still has the disadvantage that odds are not quoted daily and so must be interpolated also the present study attempts to measure the importance of political control of the environmental bureaucracy the existing literature focused on a variety of other federal agencies and industries iii data and empirical model data the dependent variable used here is the abnormal daily returns to the stock market price of a company that has environmental litigation outstanding on the day of an election the idea is that if the market considers the company to be politically sensitive then the returns to the company s shares should respond to changes in the probability of a political event as reported by the iem the stock market data comes from the center for research in security prices cr sp 4 the article uses individual company returns as opposed to the construction of portfolios of stocks that are then combined with data on returns to the portfolio as used by roberts 1990b and herron et al 1999 the present paper uses interaction terms between the likelihood of political events and individual characteristics of the companies such as the industry that they are in and the number of times they have been sued before this is not possible when aggregate portfolio returns are used because that would not allow the isolation of disaggregated individual company effects

differential impact on bank valuation of interstate banking law changes abstract by 1988 forty seven states and the district of columbia had enacted legislation liberalizing interstate banking restrictions this study systematically investigates the market impact of these law changes on bank stock prices using an event parameter event study methodology we assess the differential impact on in state and out of state banks to a given state law change we also assess the differential impact of law changes upon banks included in or excluded from any regional compacts among states money center banks are treated as a special class of out of state or excluded banks we find that out of state and out of region banks excluding money center banks have profited most from these law changes and money center banks have been least positively affected both at the time of enactment and at the effective date of the law changes we attribute these findings to the opening of interstate banking opportunities to other than money center and foreign banks thus leveling the playing field
