corporate philanthropy ownership type and financial transparency drawing on stakeholder theory and the concept of enlightened self interest we argue that firms that actively engage in corporate philanthropic giving also tend to demonstrate greater concern for investors interests by providing more transparent financial information and avoiding corporate misconduct moreover the relationships between corporate giving financial information transparency and corporate misconduct vary significantly according to the firm s ownership type which affects the fundamental motivations for corporate philanthropy in a sample of chinese publicly listed firms from the 2003 2009 period we find a positive relationship between corporate giving and financial transparency and note that the relationship is stronger for non state owned enterprises non soes we also find a significantly negative association between corporate giving and corporate misconduct for non soes but not for soes taken together these findings suggest that responsibility to both stakeholders and shareholders is a vital part of building trust and reputations in china s non soe sector

do non socially responsible companies achieve legitimacy through socially responsible actions the mediating effect of innovation this study investigates the effects on organization s financial performances of first the extent to which the organizations are involved in controversial business activities and second their level of social performance these companies can be considered non socially responsible given the harmful nature of the activities they are involved in managers of these companies may still have incentives to pursue socially responsible actions if they believe that engaging on those actions will help them to achieve legitimacy and improve investors perception about them we develop a comprehensive methodology to investigate these corporate social performance csp related effects in a complex but specific setting to this end we analyze a sample of 202 us firms for the period 2005 2008 using a novel method in this area partial least squares our results indicate that contrary to the general findings in prior literature companies involved in controversial business activities which engage in csp do not directly reduce the negative perception that stakeholders have about them instead we found evidence of a positive mediation effect of csp on financial market based performance through innovation

exploring the valuation of corporate social responsibility a comparison of research methods this paper argues the case that tests of how investors value corporate social performance csp based upon realised stock market returns are liable to be weak tests if markets are efficient and firms change csp policies infrequently we provide a theoretical explanation of why this will be the case using examples to illustrate subsequently we set out an alternative theoretical framework for the purposes of investigating whether markets place a positive or a negative valuation on csp and show why this is superior to tests based upon tobin s q using us kld data we demonstrate that as theorised markets place a positive value on csp that is not detected by conventional returns based tests our conclusion is that researchers who are interested in the question of whether engagement with a corporate social responsibility agenda is a value enhancing activity for a company as argued by some stakeholder theorists or value destructive as argued by friedman the social responsibility of business is to increase its profits the new york times magazine 1970 need to look beyond returns based tests to answer the research question posed

the value relevance of reputation for sustainability leadership this study investigates whether the market valuation of the two summary accounting measures book value of equity and net income is higher for firms with reputation for sustainability leadership when compared to firms that do not enjoy such reputation the results are interpreted through the lens of a framework combining signalling theory and resource based theory according to which firms signal their commitment to sustainability to influence the external perception of reputation a firm s reputation for being committed to sustainability is an intangible resource that can increase the value of a firm s expected cash flows and or reduce the variability of its cash flows our findings are according to expectations and show that the net income of firms with good sustainability reputation has a higher valuation by the market when compared to their counterparts

financial innovation and information the role of derivatives when a market for information exists we study the effects of financial innovation in a model of endogenous information acquisition we determine the conditions under which the introduction of a derivative written on an existing stock increases or decreases the incentive to purchase information we show that financial innovation produces some effects which hold across informational structures and others which differ the former coincide with the few empirical results that are robust in the literature effects on prices risk premia and volatility while the latter coincide with the ones that differ experiment by experiment effects on volume correlation between volume and volatility and market informational efficiency copyright 2002 oxford university press

a theory of trading volume a theory of trading volume is developed based on assumptions that market agents frequently revise their demand prices and randomly encounter potential trading partners the model describes two distinct ways informational events affect trading volume one is consistent with conjectures made by empirical researchers that investor disagreement leads to increased trading but the observation of abnormal trading volume does not necessarily imply disagreement and volume can increase even if investors interpret the information identically if they also have had divergent prior expectations simulation tests support the model and are used to contrast the random pairing environment with costless market clearing volume is lower in the costly market and volume increases caused by an informational event persist after the event period this is consistent with existing empirical evidence and suggests that markets do not immediately clear all orders or that investors have demands to recontract

how do different designs of energy labels influence purchases of household appliances a field study in switzerland abstract energy labels are a key element of energy efficiency policies they provide information on appliances energy consumption and aim at increasing consumers attention to this characteristic a well known example is the eu energy label which is required by law to be displayed on most energy using durables in the eu as well as in switzerland in cooperation with a large online retailer in switzerland we assess the impact of the eu energy label and of a newly designed monetary lifetime oriented energy label in the field we analyze private purchases of household appliances especially freezers vacuum cleaners and tumble dryers we find that the display of any of the two energy labels increases the sales proportion of energy efficient appliances compared to the absence of any energy label at the same time we observe a volume effect for freezers the average size of purchased freezers is larger when any of the two energy labels is displayed compared to the absence of any energy label the influence of the two different energy labels is similar except for vacuum cleaners for which monetary information might have an adverse effect

is there an energy efficiency gap many analysts have argued that energy efficiency investments offer an enormous win win opportunity to both reduce negative externalities and save money this overview paper presents a simple model of investment in energy using capital stock with two types of market failures first uninternalized externalities from energy consumption and second forces such as imperfect information that cause consumers and firms not to exploit privately profitable energy efficiency investments the model clarifies that only if the second type of market failure cannot be addressed directly through mechanisms such as information provision energy efficiency subsidies and standards may be merited this chapter therefore reviews the empirical work on the magnitude of profitable unexploited energy efficiency investments a literature which frequently does not meet modern standards for credibly estimating the net present value of energy cost savings and often leaves other benefits and costs unmeasured these problems notwithstanding recent empirical work in a variety of contexts implies that on average the magnitude of profitable unexploited investment opportunities is much smaller than engineering accounting studies suggest finally there is tremendous opportunity and need for policy relevant research that utilizes randomized controlled trials and quasi experimental techniques to estimate the returns to energy efficiency investments and the welfare effects of energy efficiency programs

the misleading effect of energy efficiency information on perceived energy friendliness of electric goods the european union energy label informs consumers at the point of sale about the energy efficiency and electricity consumption of various electric goods the label should enable consumers to purchase energy friendly products i e products with low energy consumption thereby making a significant contribution to the reduction of overall energy consumption this paper offers a systematic analysis of consumers interpretation of the energy label the results of a set of experimental studies revealed that consumers tend to base their estimates of a product s energy consumption mainly on the energy efficiency class e g a communicated on the energy label and largely ignore information about annual electricity consumption e g 120 kwh year thereby consumers potentially overestimate the energy friendliness of a product assigned a high energy efficiency rating this also holds true when consumers directly compare two products in terms of energy friendliness thus participants chose a higher consuming product because it had a high energy efficiency rating high energy efficiency ratings e g a can distort consumers perceptions of product categories that consume excessively e g freezers participants were seduced into thinking that a high energy efficiency rating e g a means the energy consumption of energy hogs is no longer problematic this paper provides evidence that the energy label could have a contrary effect than the one intended due to people s susceptibility to an energy efficiency fallacy this misinterpretation of the energy label could further explain why overall energy demand is increasing despite enhanced energy efficiency finally implications for policy makers and further research for enhancement of the energy label are discussed

option listing and stock returns abstract this article examines the effect of option introductions on the underlying stocks in addition to the price increase and volatility decrease that take place when new options are listed we obtain and explain the following new empirical results i an increase in the value of the market around the listing dates of new options ii an increase in the value of an industry index which excludes the optioned stocks iii the dissipation of the price and volatility effects in recent periods and iv the existence of an announcement effect in one subperiod of our sample and its dissipation in recent periods

option prices as predictors of equilibrium stock prices the black scholes option pricing model modified for dividend payments is used to calculate jointly implied stock prices and implied standard deviations a comparison of the implied stock prices with observed stock prices reveals that the implied prices contain information regarding equilibrium stock prices that is not fully reflected in observed stock prices the implications of this finding are discussed this study investigates the role of call option prices as predictors of the equilibrium prices of their underlying stocks using the black scholes 3 bs model previous tests of the bs model have shown that the formula is highly successful in explaining the observed market prices of options see black and scholes 2 galai 8 chiras and manaster 6 and macbeth and merville 12 according to the model the option price is a function of the current value of the underlying stock the instantaneous variance of the stock s rate of return the time to maturity of the option the risk free rate of interest and the exercise price of the option 1 given an observed option price and known values of all input parameters to the bs model except the stock price one can determine the price of the underlying stock that equates the observed option price to its calculated value it follows from the underlying logic of the model that the implied price is the value of the underlying stock for which a continuously revised option bond portfolio would be a perfect substitute for the stock hence if options are actually priced according to the model implied stock prices will be the option market s assessment of equilibrium stock values previous empirical studies have assumed that observed stock prices are the relevant stock prices for option valuation however just as stock prices may differ in the short run from one exchange to another i e nyse midwest

the effect of derivative assets on information acquisition and price behavior in a rational expectations equilibrium this article shows that introducing derivative assets increases incentives to collect information about asset payoffs the increase in information collection makes the price of the underlying asset more informative and causes the expected price to increase extending the model to a dynamic setting with multiple risky assets we find the introducing derivative assets for one asset increases the expected prices of positively correlated assets and reduces price reaction to future earnings announcements these findings are consistent with the bulk of the empirical evidence on the relationship between the introduction of derivative assets and the behavior of asset prices article published by oxford university press on behalf of the society for financial studies in its journal the review of financial studies

asymmetric information and options in an extension of the kyle 1985 model of continuous insider trading it is shown that asymmetric information can make it impossible to price options by arbitrage even when an option would appear to be redundant its introduction into the market can cause the volatility of the underlying asset to become stochastic this eliminates the potential for dynamically replicating the option the change in the price process of the asset reflects a change in the information transmitted by volume and prices when the option is traded article published by oxford university press on behalf of the society for financial studies in its journal the review of financial studies

being good while being bad social responsibility and the international diversification of us firms this paper contributes to the discussion on international diversification and corporate social responsibility csr by suggesting that firms can be simultaneously socially responsible and socially irresponsible to test our assertions we analyze data from 222 publicly traded us firms from 1993 to 2003 the findings support our hypotheses and have significant implications for the way in which we conceptualize csr

the information content of institutional trades on the london stock exchange we construct a unique data set that includes all reported institutional block trades on the london stock exchange and analyze the market reaction to buy and sell trades we find that the type of investors behind the trade and the combination of the trade s size and the trader s resulting level of ownership are the major determinants of the information effects and the asymmetry between price impacts of buy and sell trades in particular large trades undertaken by fund managers the most active investors in our sample have strong information content while for the remaining trades we report limited support for the information and the price impact asymmetry hypotheses these results hold even after accounting for trade complexity and volatility effects in the regressions

cognitive reflection and the valuation of energy efficiency abstract based on a stated choice experiment among about 3 600 german households heads on the purchase of electricity using durables this paper explores how cognitive reflection influences consumers valuation of energy efficiency and investigates the interaction with consumers response to the eu energy label our results indicate that consumers with low cognitive reflection value energy efficiency less furthermore we demonstrate that consumers with a low level of cognitive reflection primarily choose appliances based on grade like energy efficiency classes rather than detailed information on annual energy use

gaining access by doing good the effect of sociopolitical reputation on firm participation in public policy making this paper examines the role of firms sociopolitical reputations as proxied by their perceived engagement in socially responsible practices in public policy makers decisions to grant access in the policy making process i argue that policy makers dependencies motivations and decision making processes lead them to evaluate firms by using sociopolitical reputation as a differentiating heuristic i hypothesize that firms that construct stronger sociopolitical reputations will be granted greater access and that firms existing political activity and policy makers partisanship will moderate this relationship i test these hypotheses using an 11 year panel on congressional testimony reputation and political and financial characteristics for the s p 500 and find support for all three these findings support the existence of a sociopolitical dimension to firms reputations that affects how public policy makers evaluate firms demonstrating that corporate social responsibility pays political benefits this paper was accepted by jesper sorensen organizations

ballot position choice fatigue and voter behaviour in this paper we examine the eect of choice fatigue on decision making we exploit a natural experiment in which voters face the same contest at dierent ballot positions due to dierences in the number of local issues on their ballot facing more decisions before a given contest signi cantly increases the tendency to abstain or rely on decision shortcuts such as voting for the status quo or the rst listed candidate we estimate that without choice fatigue abstentions would decrease by 8 and 6 of the propositions in our dataset would have passed rather than failed

an investigation of real versus perceived csp in s p 500 firms firms are spending billions annually in the name of corporate social responsibility csr whilst markets are increasingly willing to reward good and responsible firms they lack the instruments to measure corporate social performance csp to convince investors and other stakeholders firms invest heavily in building a reputation for good corporate behaviour this article argues that reputations for csp are often unrepresentative of true csp and investigates how differences in perceived and actual as measured by the fortune and kld databases respectively can partly be explained by firm characteristics amongst other things it finds that overrated firms are more likely to be relatively big profitable operating in non polluting but competitive industries and with no history of wrong doings to their primary stakeholders they will also typically spend a lot of effort satisfying the claims of their secondary stakeholders above all the results emphasise the need for researchers to recognise that the databases measure different phenomenon and are not interchangeable

shareholder value stakeholder management and social issues what s the bottom line we test the relationship between shareholder value stakeholder management and social issue participation building better relations with primary stakeholders like employees customers suppliers and communities could lead to increased shareholder wealth by helping firms develop intangible valuable assets which can be sources of competitive advantage on the other hand using corporate resources for social issues not related to primary stakeholders may not create value for shareholders we test these propositions with data from s p 500 firms and find evidence that stakeholder management leads to improved shareholder value while social issue participation is negatively associated with shareholder value copyright 2001 john wiley sons ltd

corporate philanthropic giving advertising intensity and industry competition level this article examines whether the likelihood and amount of firm charitable giving in response to catastrophic events are related to firm advertising intensity and whether industry competition level moderates this relationship using data on chinese firms philanthropic response to the 2008 sichuan earthquake we find that firm advertising intensity is positively associated with both the probability and the amount of corporate giving the results also indicate that this positive advertising intensity philanthropic giving relationship is stronger in competitive industries and firms in competitive industries are more likely to donate this study thus provides evidence suggesting that even in the wake of catastrophic events corporate philanthropic giving is strategic

option volume and stock prices evidence on where informed traders trade this paper investigates the informational role of transactions volume in options markets we develop an asymmetric information model in which informed traders may trade in option or equity markets we show conditions under which informed traders trade options and we investigate the implications of this for the linkage between markets our model predicts an important informational role for the volume of particular types of option trades we empirically test our model s hypotheses with intraday option data our main empirical result is that negative and positive option volumes contain information about future stock prices the information content of trading activity is a subject of widespread interest if trades are correlated with private information then the outcome of the transaction process may portend future movements in price the extension of trading to different venues or to derivative instruments however means that this link between transactions and information need not be easily discernible if there are alternative markets in which informed traders can profit from their information then where informed traders choose to trade may have important implications not only for security p rice movements but for the behavior of related prices as well this suggests that transactions in derivative markets may be an important predictor of future security price movements in this paper we investigate the informational role of transactions volume in options markets for some readers this focus may seem puzzling an option is a derivative security so its price should be dictated unilaterally by the behavior of the stock price this unidirectional linkage is only true however in complete markets if information is impounded into prices by trading then the ability of informed traders to transact in options markets mearns

the value of corporate philanthropy during times of crisis the sensegiving effect of employee involvement recent research suggests that philanthropy s value to the firm is largely mediated by contextual factors such as managers assumed motives for charity our article extends this contingency perspective using a sensegiving lens by which external actors interpretations of organizational actions may be influenced by the way in which the organization communicates about those actions we consider how sensegiving features in philanthropy related press releases affect whether investors value those donation decisions for the empirical investigation in this study we analyze abnormal returns to announcements by u s fortune 500 firms documenting their donations to hurricane katrina disaster relief in 2005 we expect that in general donation decisions would be controversial given the uncertainty surrounding the hurricane s economic effects at the time however we also propose that announcements emphasizing employee involvement in the donation send investors positive signals about the firm s ability to bounce back from the disaster s adverse effects we find empirical support for the proposed hypotheses and discuss the implications for theory and practice

stealth trading in options markets we investigate how price discovery occurs in the options markets through traders trade size choice by employing transactions data on all options traded on a sample of 100 firms we show that informed traders fragment their orders into small medium trades for low high volume contracts we also find that almost 60 of the price discovery occurs in the exchange with the largest market share for a given option where informed traders favor medium size trades upon examining distinct option series for a given stock we find that at the money calls display the highest information share

behavioral economics and energy conservation a systematic review of non price interventions and their causal effects abstract research from economics and psychology suggests that behavioral interventions can be a powerful climate policy instrument this paper provides a systematic review of the existing empirical evidence on non price interventions targeting energy conservation behavior of private households specifically we analyze four nudge like interventions referred to as social comparison commitment devices goal setting and labeling in 44 international studies comprising 105 treatments this paper differs from previous systematic reviews by solely focusing on studies that permit the identification of causal effects we find that all four interventions have the potential to significantly reduce energy consumption of private households yet effect sizes vary immensely we conclude by emphasizing the importance of impact evaluations before rolling out behavioral policy interventions at scale

the price effect of option introduction this paper examines the price effect of option introduction from 1974 to 1980 the introduction of individual options causes a permanent price increase in the underlying security beginning approximately three days before introduction the price effect appears to be associated with introduction and not announcement throughout the sample period excess returns volatility declines with option introduction systematic risk is unchanged there is a positive relation between the price increase and a measure of activity in the options market copyright 1989 by american finance association

integrated dynamic models for hedging international portfolio risks abstract we develop scenario based stochastic programming models for hedging the risks of international portfolios using options the models provide increasing level of integration in managing market and foreign exchange fx risks we start with a single stage model with currency options for selective hedging of fx risks while market risk is addressed through diversification we add stock options to hedge market risks and add quantos and currency options to develop an integrated model using an innovative method to price quantos on the scenario tree underpinning the stochastic program the models are extended to multi stage settings backtesting on market data over a 14 year period that includes the global financial crisis of 2008 we demonstrate the effectiveness of taking increasingly integrated views of risk management simultaneous hedging of market and fx risks using stock and currency options has the best ex post performance the differences are economically significant and statistical significance is established through rigorous hypothesis testing the models are particularly effective during the crisis test results show that two stage models outperform their single stage counterparts regardless of the hedging strategy

are risk aversion and impatience related to cognitive ability is the way that people make risky choices or tradeoffs over time related to cognitive ability this paper investigates whether there is a link between cognitive ability risk aversion and impatience using a representative sample of the population and incentive compatible measures we conduct choice experiments measuring risk aversion and impatience over an annual time horizon for a randomly drawn sample of roughly 1 000 german adults subjects also take part in two different tests of cognitive ability which correspond to sub modules of one of the most widely used iq tests interviews are conducted in subjects own homes we find that lower cognitive ability is associated with greater risk aversion and more pronounced impatience these relationships are significant and robust to controlling for personal characteristics educational attainment income and measures of credit constraints we perform a series of additional robustness checks which help rule out other possible confounds

an investigation into the givings by large corporate donors to uk charities 1979 86 this paper the first study of its kind to date carried out for the uk is concerned with the scale and determinants of charitable givings by large corporate donors in the uk the investigation is carried out using pooled information on 53 companies over the 8 years from 1979 to 1986 during which period the rate of corporation tax fell from 52 to 35 a result of particular interest is that contributions were related positively to the rate of tax

information aggregation in a noisy rational expectations economy abstract this paper analyzes a general equilibrium model of a competitive security market in which traders possess independent pieces of information about the return of a risky asset each trader conditions his estimate of the return both on his own private source of information and price which in equilibrium serves as a noisy aggregator of the total information observed by all traders a closed form characterization of the rational expectations equilibrium is presented a counter example to the existence of fully revealing equilibrium is developed

why option prices lag stock prices a trading based explanation while many studies find that option prices lead stock prices stephan and wvhaley 1990 find that stocks lead options we find no evidence that options even deep out of the money options lead stocks after confirming stephan and whaley s results we show their results can be explained as spurious leads induced by infrequent trading of options we show that the stock lead disappears when the average of the bid and ask prices is used instead of transaction prices hence we find no evidence of arbitrage opportunities associated with the stock lead in a perfect market price discrepancies should be instantly arbitraged away in particular option prices should neither lead nor lag stock prices in real markets only very short leads should occur traders with private information who are confident that their information is valid and that they will not be detected generally want highly leveraged positions to exploit their advantage thus we might expect options with their greater leverage to lead stocks if information trading is important manaster and rendleman 1982 bhattacharya 1987 and anthony 1988 find evidence that options

option listing and the stock price response to earnings announcements abstract we examine the effect of option listing on the immediate stock price response to earnings announcements contrary to prior studies using earlier data we find firms initiating option trading after 1986 fail to exhibit a significant decline in earnings response we then examine 420 firms initiating option trading during 1973 1993 in a series of tests controlling for market wide effects and changing firm size we find some evidence that option listing may actually increase the stock price response to earnings but no evidence listing reduces the response both longitudinal and cross sectional tests produce similar results

earnings announcements stock price adjustment and the existence of option markets this paper employs a new approach to study the effects of option trading on the behavior of underlying stock prices extant research compares distributional properties of the stock price at two points in time divided by an event in the option market that might affect price behavior as an alternative we examine the stock price adjustment to the release of quarterly earnings using samples of firms with and without listed options we find the two samples exhibit different adjustment processes with the nonoption firms requiring substantially more time to adjust since the advent of organized stock option trading the investment community

corporate philanthropy in the u k 1985 2000 some empirical findings this paper briefly reviews the theories that seek to explain the phenomenon of corporate charitable donations and then provides a review of the empirical issues that have arisen in previous studies in this area the findings of an analysis of charitable donations data from the entire u k ftse index for the years 1985 2000 are then reported these findings include the observation of a time related increase in charitable donations which is compared with an earlier study to give a 24 year history of charitable donations in the u k the findings note little responsiveness of the monetary value of charitable donations to the economic performance of firms an international comparison over time against u s trends is also reported and shows how u s corporations have traditionally been more generous than u k firms but that the trend in the u s is downwards membership of a u k based tithing club the percent club is shown to be associated with higher profit performance against non members members charitable contributions against profit are shown to be higher than the ftse mean although short of the 0 5 target figure in cash terms the paper concludes with a brief discussion of these findings in relation to the theoretical positions advanced for corporate philanthropy

attraction or distraction corporate social responsibility in macao s gambling industry this paper attempts to investigate how and why organisations in macao s gambling industry engage in corporate social responsibility csr it is based on an in depth investigation of macao s gambling industry with 49 semi structured interviews conducted in 2011 we found that firms within the industry were emphasising pragmatic legitimacy based on both economic and non economic contributions in order to project positive images of the industry while glossing over two domains of adverse externalities problem gambling among visitors and the pollution and despoliation of the environment by engaging symbolically rather than substantively in csr the gambling firms were diverting attention away from issues of moral legitimacy in order to be allowed to continue to pursue business as usual as a means of obtaining substantial financial returns in a social cultural and socio political context that was exerting relatively little public pressure to improve corporate social and environmental performance we conjecture that the gambling firms were feeding on borrowed time

corporate donations and shareholder value do corporate donations enhance shareholder wealth or reflect agency problems we address this question for a global sample of firms whereby we distinguish between charitable and political donations as well as between donations in cash and in kind we find that charitable donations are positively related to financial performance and firm value which is consistent with the value enhancement hypothesis this positive effect on firm value is stronger for cash than in kind donations in contrast political donations do not appear to enhance shareholder value but rather tend to reflect agency problems as they are higher for firms with poor internal corporate governance and strong managerial entrenchment we address endogeneity concerns by using peer firms donations as an instrument in a two stage least squares 2sls setting and by conducting a difference in difference analysis around a general election

the economic side effects of dangerous drug announcements immediately prior to the passage of the 1962 food and drug administration amendments there were a number of drugs recalled from markets worldwide announcements about the dangerous side effects of these drugs were associated with lower share prices for their manufacturers and the industry as a whole we perform several analyses to sort out alternative explanations for the observed declines we find that dangerous drug announcements had no effect on the sales of other drugs and did not affect the share values of european drug makers doing little business in the united states we also find that share price reductions associated with recalls in the 1970s and 1980s were confined to the manufacturers of the recalled drugs these patterns are consistent with the hypothesis that drug company shareholders viewed the recalls in the early 1960s as signals of an increase in the cost of compliance with new and more stringent drug testing requirements

corporate reputation and philanthropy an empirical analysis this paper analyzes the determinants of corporate reputation within a sample of large uk companies drawn from a diverse range of industries we pay particular attention to the role that philanthropic expenditures and policies may play in shaping the perceptions of companies among their stakeholders our findings highlight that companies which make higher levels of philanthropic expenditures have better reputations and that this effect varies significantly across industries given that reputational indices tend to reflect the financial performance of organizations above other factors fryxell g e and j wang 1994 journal of management 20 1 14 and that elements of the literature emphasise that discretionary aspects of social responsibility including corporate donations may not be in the financial interests of organizations e g friedman m 1970 the social responsibility of business is to increase its profits new york times magazine september 13 this is a significant finding it suggests that philanthropic expenditures may play a significant role in stakeholder management and may in particular lead to stakeholders holding more positive impressions of philanthropic corporations

social reporting by companies listed on the alternative investment market while the existing literature focuses on the disclosure of social information mainly by large companies this paper concentrates on the disclosure of social information by small and medium sized companies sme listed on the alternative investment market aim in the u k the paper investigates the prevalent view that smes are unlikely to report social information due to their financial constraints and the perception that they have very little social conduct on which to report our overall evidence illustrates that contrary to this view smes report social information regardless of their financial constraints most likely in the same manner as large companies do because they realise the significance of social reporting in establishing and retaining their corporate reputation

going to haven corporate social responsibility and tax avoidance this study examines the endogenous relation between corporate social responsibility csr and tax avoidance by focusing on a common strategy of corporate tax avoidance i e establishing entities in offshore tax havens using hand collected data on a sample of u s firms we find that firms csr ratings increase substantially in the two years after they first open tax haven affiliates we provide evidence by using the controlled foreign corporations cfc look through rule enacted by congress in 2006 that facilitates offshore profit shifting we find that firms that are affected by the cfc legislation increase their csr practices in response overall our results are consistent with the risk management theory which argues that firms hedge against the potential negative consequences of aggressive tax avoidance practices through an increase in positive csr activities

the construct validity of the kinder lydenberg domini social performance ratings data carroll 1991 encouraged researchers in social issues management sim to continue to measure corporate social performance csp from a variety of different perspectives utilizing a variety of different measures in addition wolfe and aupperle 1991 and others have asserted that there is no single best way to measure csp and that multiple measures and perspectives help develop the field however pfeffer 1993 suggest that a lack of consistent measurement has constrained organization studies and by implication the field of social issues management in its development as a field it may be in the best interest of social issues management researchers to try to development a common body of measures and data recently kinder lydenberg and domini co kld a social choice investment advisory firm has made available their social performance database the kld data have potential to become a widely accepted set of csp measures the purpose of this paper is to present a construct validity study comparing the kld data to other measures of csp

information trade and derivative securities hellwig s 1980 model is used to analyze the value of improving trading opportunities by more frequent trading in the underlying asset or by trading in a derivative asset with multiple trading sessions uninformed investors behave as rational trend followers while more informed investors follow a contrarian strategy as trading becomes continuous pareto efficiency is achieved with trading in an appropriate derivative security pareto efficiency may be achieved in only a single round of trading all derivative claims are then priced on black and scholes 1973 principles and in the absence of further supply shocks no trading will take place in subsequent trading rounds article published by oxford university press on behalf of the society for financial studies in its journal the review of financial studies

the relation between price changes and trading volume a survey this paper reviews previous and current research on the relation between price changes and trading volume in financial markets and makes four contributions first two empiri cal relations are established volume is positively related to the magnitude of the price change and in equity markets to the price change per se second previous theoretical research on the price volume relation is summarized and critiqued and major insights are emphasized third a simple model ofthe price volume relation is proposed that is consis tent with several seemingly unrelated or contradictory observations and fourth several directions for future research are identified

price and advertising signals of product quality we present a signaling model based on ideas of phillip nelson in which both the introductory price and the level of directly uninformative advertising or other dissipative marketing expenditures are choice variables and may be used as signals for the initially unobservable quality of a newly introduced experience good repeat purchases play a crucial role in our model a second focus of the paper is on illustrating an approach to refining the set of equilibria in signalling games with multiple potential signals

continuous trading or call auctions revealed preferences of investors at the tel aviv stock exchange we use the move of israeli stocks from call auction trading to continuous trading to show that investors have a preference for stocks that trade continuously when large stocks move from call auction to continuous trading the small stocks that still trade by call auction experience a significant loss in volume relative to the overall market volume as small stocks move to continuous trading they experience an increase in volume and positive abnormal returns because of the associated increase in liquidity overall though a move to continuous trading increases the volume of large stocks relative to small stocks

equilibrium open interest abstract this paper analyses what determines an individual investor s risk sharing demand for options and aggregating across investors what the equilibrium demand for options we find that agents trade options to achieve their desired skewness specifically we find that portfolio holdings boil down to a three fund separation theorem that includes a so called skewness portfolio that agents like to attain our analysis indicates also however that the common risk sharing setup used for option demand and pricing is incompatible with a stylized fact about open interest across strikes

complete markets informed trading and equity option introductions this paper proposes and tests a new hypothesis concerning the price impact of option introductions on the underlying asset we argue that the leverage properties of options induce a higher level of informed trading in the aggregate market underlying plus derivative resulting in excess listing day price movements in the newly optioned equity using an alternative dataset our results suggest that this may be an explanation for the observed positive than negative excess listing day returns of us optioned stocks over the past thirty years

long lived private information and imperfect competition we develop a multi period auction model in which multiple privately informed agents strategically exploit their long lived information we show that such traders compete aggressively and cause most of their common private information to be revealed very rapidly in the limit as the interval between auctions approaches zero market depth becomes infinite and all private information is revealed immediately these results are in contrast to those of kyle 1985 in which the monopolistic informed trader causes his information to be incorporated into prices gradually and when the interval between auctions is vanishingly small market depth is constant over time fama 1970 defines a strong form efficient market as one in which security prices fully reflect all available information including both publicly and privately held information in a pioneering and influential article kyle 1985 develops a model in which a single privately informed trader with long lived information optimally exploits his monopoly power over time kyle s 1985 main results are i the informed trader trades in a gradual manner so that his information is incorporated into prices at a slow almost linear rate and ii when auctions are held continuously the depth of the market is constant over time however kyle s 1985 assumption of a single informed trader is strong in the sense that in actual financial markets it is reasonable to expect that at least a few players will have access to private information and will trade in the knowledge that they will face competition with other informed agents in the market 1 we develop a multi period auction model in which multiple strategic informed traders optimally exploit their long lived informational advantage we thus explore the restrictiveness of kyle s assumption of a single informed trader and also examine

the dynamics of international equity market expectations this paper develops a noisy rational expectations model of the way in which international investors adjust their expectations of asset payoffs in a given country in response not only to public information signals but also to private information signals whose precision differs across investors the model predicts that the perceptions of investors in one country about the future market returns in another country are related differently to realized past returns depending on their informational disadvantage relative to other investors the greater is that informational disadvantage the greater is the change in perception associated with returns the predictions are confirmed by monthly survey data of institutional money managers investing in developed markets from 1995 to 2000

speculations in option markets enhance allocation efficiency with heterogeneous beliefs and learning abstract many studies investigate the impact of heterogeneous beliefs in the first moment while very few in the second moment this is partially due to continuous time setup which makes it difficult to incorporate heterogeneous beliefs in the second moment in a two period exponential normal model with bayesian learning i demonstrate that heterogeneous prior variances give rise to the economic value of option markets investors speculate in option market and public information improves allocation efficiency of markets only when there is heterogeneity in prior variances heterogeneity in mean is neither a necessary nor a sufficient condition for generating speculations in option markets with heterogeneous beliefs options are non redundant assets which can facilitate side betting and enable investors to take advantage of the disagreements and the differences in confidence this fact leads to a higher growth rate in the investors certainty equivalents and thus a higher equilibrium interest rate furthermore option exhibits a unique feature of enabling signal precision to affect the ex ante risk premium of underlying asset which quadratic derivative and stock do not have

information quality and options microstructure researchers have long understood that information quality has an effect on price formation in the underlying asset market however option researchers have largely ignored the fact that information quality might also impact the options market this article characterizes the nature of the impact by showing how option prices and implied volatility levels are related to the forward looking information quality path this result follows from a noisy rational expectations model that abandons the normal distribution in favor of the gamma distribution but maintains the standard assumption of exponential utility thus the new model bridges the gap between the microstructure literature that relies so heavily on the normal exponential framework and the options literature that relies exclusively on models that are consistent with the limited liability of stock prices the model s tractability allows for a robustness check against the standard framework and provides a viable setting for analyzing the empirical implications of information quality for the options market jel d8 gl

sale of price information by exchanges does it promote price discovery exchanges sell both trading services and price information we study how the joint pricing of these products affects price discovery and the distribution of gains from trade in an asset market a wider dissemination of price information reduces pricing errors and the transfer from liquidity traders to speculators this effect reduces the fee that speculators are willing to pay for trading therefore to raise its revenue from trading a for profit exchange optimally charges a high fee for price information so that only a fraction of speculators buy this information as a result price discovery is not as efficient as it would be with free price information this problem is less severe if the exchange must compensate liquidity traders for a fraction of their losses this paper was accepted by wei xiong finance

options short sales and market completeness this paper presents empirical evidence that trading in options contributes to both transactional and informational efficiency of the stock market by reducing the effect of constraints on short sales the significantly higher average level of short interest exhibited by optionable stocks supports the argument that options facilitate short selling we also find significant effects on option prices related to the short interest in the underlying stock we then present evidence that options also increase information efficiency earlier work that is replicated and extended here has suggested that short sale constraints cause stock prices to underweight negative information options appear to reduce that effect

the energy efficiency gap what does it mean abstract as renewed attention has been given by policy makers to energy conservation issues it has frequently been asserted that an energy efficiency gap exists between actual and optimal energy use the critical questions is how to define the optimal level of energy efficiency this paper seeks to disentangle some confusing strands of argument that are frequently brought to bear on this question by identifying the major conceptual issues that determine the set of feasible answers we identify five separate and distinct notions of optimality the economists economic potential the technologists economic potential hypothetical potential the narrow social optimum and the true social optimum each of these has associated with it a corresponding definition of the energy efficiency gap our analysis demonstrates that necessary preconditions for identifying the right measure of the energy efficiency gap include understanding and disentangling market failure and non market failure explanations for the gradual diffusion of energy efficient technologies

ethical commitment financial performance and valuation an empirical investigation of korean companies a variety of stakeholders including investors corporate managers customers suppliers employees researchers and government policy makers have long been interested in the relationship between the financial performance of a corporation and its commitment to business ethics as a subject of research the relations between business ethics and corporate valuation has yet to be thoroughly quantified and investigated this article is an effort to amend this inadequacy by demonstrating a statistically significant association between ethical commitment and corporate valuation measures consistent with anecdotal evidence we have found a significant association between the ethical commitment of korean companies and their valuation on the korean stock market however the result reveals that the association between ethical commitment and financial performance is not significantly supported

firm characteristics and analyst following abstract this paper examines the major determinants of the number of analysts following a firm a simple model of analyst following is proposed and several firm characteristics are suggested that are likely to influence the extent of a firm s analyst following by either affecting the aggregate demand for or supply of analyst services or both for the firm almost all of these characteristics are found to be strongly significant in affecting the extent of analyst following of firms and the empirical results generally accord well with economic intuition

why do corporations give to charity this paper explores whether corporate contributions should be tax dedu ctible within the more general context of an examination of the profi t and utility maximization motives driving contributions the theoret ical section develops a formal structural model of the contributions process illustrates comparative statics and derives a set of empiri cally testable hypotheses using a new source of firm data the empir ical results indicate that profit maximization is an important motive driving contributions this finding supports the current tax deducti ble status of contributions up to a seldom encoun tered ceiling and favors a reform that allows firms to treat contributions as ordinary business expenses copyright 1988 by the university of chicago

the impact of public scrutiny on corporate philanthropy this paper proposes that a corporation s vulnerability to public scrutiny drives its corporate giving the hypothesis that companies donate for strategic motives is tested against the alternative that they do so for altruistic reasons court cases and news articles were selected as proxies for public scrutiny macroeconomic variables were used to gauge the level of public charitable need and test for altruism through examining the philanthropic behavior of 40 fortune 500 companies over 7 years this paper finds that companies are strategic and altruistic in their giving

informed speculation with imperfect competition competitive rational expectations models have the unsatisfactory property dubbed the schizophrenia problem by hellwig that each trader takes the equilibrium price as given despite the fact that he influences that price an examination of information aggregation in a non competitive rational expectations model using a nash equilibrium in demand functions shows that the schizophrenia problem is avoided by having each trader take into account the effect his demand has on the equilibrium price given a distribution of private information across traders prices reveal less information than in the competition equilibrium and prices no longer become fully informative in the limit as noise trading vanishes or as traders become risk neutral with small traders the model may become one of monopolistic competition not perfect competition in contrast to the competitive model a reasonable model of endogenous acquisition of costly private information is obtained even when traders are risk neutral

the liability of good reputation a study of product recalls in the u s automobile industry in this paper we explore opposing theoretical claims about how organizational reputation affects market reactions to product defects on the one hand good reputation could be a disadvantage because expectations about product quality are more likely to be violated by defects in highly reputed products on the other hand a good reputation could be an advantage because of strong inertial effects on reputation orderings we empirically test these competing hypotheses using data on product recalls in the u s automobile industry from 1975 to 1999 our results support for the idea that reputation can be an organizational liability in that highly reputed firms suffer more market penalty as a result of their product recalls we also propose that the reputational effects are moderated by two important factors substitutability and generalism specialism our results show that having few substitutes with an equivalent level of reputation or a focused product identity stemming from specialism buffers the negative market reactions to product recalls we conclude with a discussion on the implications of these results for institutional reputation and status theories

risk aversion market liquidity and price efficiency a model of a noncompetitive speculative market is analyzed in which privately informed traders and market makers are risk averse market liquidity is found to be nonmonotonic in the number of informed traders their degree of risk aversion and the precision of their information it is also shown that increased liquidity trading leads to reduced price efficiency and that under endogenous information acquisition market liquidity may also be nonmonotonic in the variance of liquidity trades article published by oxford university press on behalf of the society for financial studies in its journal the review of financial studies

the corporate social performance financial performance link strategic managers are consistently faced with the decision of how to allocate scarce corporate resources in an environment that is placing more and more pressures on them recent scholarship in strategic management suggests that many of these pressures come directly from sources associated with social issues in management rather than traditional arenas of strategic management using a greatly improved source of data on corporate social performance this paper reports the results of a rigorous study of the empirical linkages between financial and social performance corporate social performance csp is found to be positively associated with prior financial performance supporting the theory that slack resource availability and csp are positively related csp is also found to be positively associated with future financial performance supporting the theory that good management and csp are positively related 1997 by john wiley sons ltd
