the determinants and performance impact of outside board leadership outside board chairs are more likely in firms that are smaller have greater stock volatility and research and development intensity and have a lower proportion of inside directors and less institutional ownership they are also more likely when chief executive officers have shorter tenure and lower ownership we also find that the existence of an outside chair is associated with geographical and industry norms an outside chair is positively associated with firm performance a finding robust to various estimation methods including event study and multivariate analyses incorporating controls for endogeneity as well as market and accounting measures of performance we note however that the relationship between outside chair and firm performance varies with firm characteristics

alternative value elicitation formats in contingent valuation mechanism design and convergent validity abstract to date much of the theoretical work on the incentive properties of contingent valuation surveys has focused on the oft recommended single binary choice sbc referendum format this work has identified conditions under which an sbc elicitation is incentive compatible and empirical evidence lends support to the predictive power of the theory nevertheless researchers and practitioners commonly use alternative elicitation formats and defend their design choices based on efficiency and other criteria in this study we demonstrate that it is possible to identify conditions under which alternative elicitation formats are incentive compatible using as examples open ended oe and payment card pc question formats we then implement theory informed value elicitations in the context of a flood control policy for new york city we fail to reject convergent validity in mean willingness to pay when comparing the theory driven oe format with sbc but reject convergent validity between the theory driven pc and sbc formats as an informative counterfactual we find that a standard oe elicitation congruent with prior work leads to significantly lower values and a lower proportion of respondents who view the elicitation as consequential

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

sustainable development and corporate performance a study based on the dow jones sustainability index the goal of this paper is to examine whether business performance is affected by the adoption of practices included under the term corporate social responsibility csr to achieve this goal we analyse the relation between csr and certain accounting indicators and examine whether there exist significant differences in performance indicators between european firms that have adopted csr and others that have not the effects of compliance with the requirements of csr were determined on the basis of firms included in the dow jones sustainability index djsi and specific accounting indicators were applied to measure performance for the purposes of this study we selected one group of firms belonging to the djsi and another comprised of firms quoted on the dow jones global index djgi but not on the djsi the sample was made up of two groups of 55 firms studied for the period 1998 2004 empirical analysis supports the conclusion that differences in performance exist between firms that belong to the djsi and to the djgi and that these differences are related to csr practices we find that a short term negative impact on performance is produced

demand curves for stocks do slope down new evidence from an index weights adjustment weights in the toronto stock exchange 300 index are determined by the market values of the included stocks public floats in november 1996 the exchange implemented a previously announced revision of its definition of the public float this revision which increased the floats and the index weights of 31 stocks conveyed no information and had no effect on the legal duties of shareholders affected stocks experienced statistically significant excess returns of 2 3 percent during the event week and no price reversal occurred as trading volume returned to normal levels these findings support downward sloping demand curves for stocks an obvious event with which to examine the slope of demand curves for stocks is one that changes supply in the absence of new information a shift in supply should not affect stock prices if demand curves for stocks are flat scholes 1972 using a sample of secondary equity distributions asks whether stocks are unique works of art or merely abstract claims to residual cash flows with many close substitutes as is assumed in much of finance theory scholes finds that the negative price impact of secondary offerings depends on the seller s identity implying the revelation of unfavorable informationand rules out a pure supply effect mikkelson and partch 1985 also using a sample of registered and unregistered secondary offerings find weak evidence of downward sloping demand curves but are unable to cleanly distinguish this explanation from the alternative explanation based on unfavorable information a different class of events additions to widely followed stock market indexes ostensibly provides a setting where information effects should not be present shleifer 1986 documents a permanent price increase for stocks

a credible approach for measuring inframarginal participation in energy efficiency programs abstract economists have long argued that many recipients of energy efficiency subsidies may be non additional getting paid to do what they would have done anyway demonstrating this empirically has been difficult however because of endogeneity concerns and other challenges in this paper we use a regression discontinuity analysis to examine participation in a large scale residential energy efficiency program comparing behavior just on either side of several eligibility thresholds we find that program participation increases with larger subsidy amounts but that most households would have participated even with much lower subsidy amounts the large fraction of inframarginal participants means that the larger subsidy amounts are almost certainly not cost effective moreover the results imply that about half of all participants would have adopted the energy efficient technology even with no subsidy whatsoever

how does the stock market value corporate social performance when behavioral theories interact with stakeholder theory this study examines how the reference point effect and sunk cost fallacy interact with stakeholder theory and influence how investors evaluate corporate social performance we propose that ex ante pre ipo corporate social performance influences ex post post ipo perceived riskiness and that this relationship is u shaped we also evaluate how ceo duality and company age moderate this u shaped relationship using young and newly public entrepreneurial firms in china and focusing on stock returns in the secondary market empirical results and robustness tests provide strong support for our hypotheses

do stock investors value corporate sustainability evidence from an event study this paper analyzes the impacts of index inclusions and exclusions on corporate sustainable firms by studying a sample of us stocks that are added to or deleted from the dow jones sustainability world index over the period 2002 2008 the impacts are measured in terms of stock return risk and liquidity we cannot find any strong evidence that announcement per se has any significant impact on stock return and risk however on the day of change index inclusion exclusion stocks experience a significant but temporary increase decrease in stock return liquidity deteriorates after the announcement day and bounces back significantly near the day of change systematic risk shows little change after announce ments but idiosyncratic risk is higher after announcements the overall results support harris and eitan s the journal of finance41 4 815 829 1986 price pressure hypothesis which posits that event announcement does not carry information and any shift in demand and hence the corresponding price change and liquidity change is temporary

management ownership and market valuation an empirical analysis we investigate the relationship between management ownership and market valuation of the firm as measured by tobin s q in a 1980 cross section of 371 fortune 500 firms we find evidence of a significant nonmonotonic relationship tobin s q first increases then declines and finally rises slightly as ownership by the board of directors rises for older firms there is evidence that q is lower when the firm is run by a member of the founding family than when it is run by an officer unrelated to the founder

information costs and liquidity effects from changes in the dow jones industrial average list we examine the stock market effect of changes in the composition of the dow jones industrial average djia unlike s p 500 listing studies we find that the price and the trading volume of newly listed djia firms are unaffected we attribute this result to a lack of index fund rebalancing since index trading is limited for most of our sample period and index funds mimic the s p 500 not the djia firms removed from the index however experience significant price declines we consider information signaling price pressure imperfect substitutes and information cost liquidity explanations for these asymmetric findings the evidence is consistent with the information cost liquidity explanation which holds that investors demand a premium for higher trading costs and for holding securities that have relatively less available information

agency relationships in family firms theory and evidence does owner management necessarily eliminate the agency costs of ownership drawing on agency literature and on the economic theory of the household we argue that private ownership and owner management expose privately held owner managed firms to agency threats ignored by jensen s and meckling s 1976 agency model private ownership and owner management not only reduce the effectiveness of external control mechanisms they also expose firms to a self control problem created by incentives that cause owners to take actions which harm themselves as well as those around them jensen 1994 p 43 thus shareholders have incentive to invest resources in curbing both managerialand owner opportunism we extend this thesis to the domain of the family firm after developing hypotheses which describe how family dynamics and specifically altruism exacerbate agency problems experienced by these privately held owner managed firms we use data obtained from a large scale survey of family businesses to field test our hypotheses and find evidence which suggests support for our proposed theory finally we discuss the implications of our theory for research on family and other types of privately held owner managed firms

dependability and organizational bankruptcy an application of agency and prospect theory this paper proposes and tests a new model of organizational bankruptcy based on agency and prospect theory the paper argues that debtors with unprestigious top managers low liquidity and high leverage signal that they will be undependable exchange partners the model proposes that survival is contingent on maintaining an acceptable minimum level of these financial and managerial assets if a firm falls below that threshold level it has a higher probability of bankruptcy because creditors withdraw their financial support from the debtor consistent with agency theory this implies that bankruptcy can be viewed as the legal resolution of severe shareholder creditor conflicts about the levels of financial and managerial assets that the debtor should maintain this new model proposes that maintaining a minimum level of these assets is a necessary but not sufficient condition for bankruptcy some undependable firms delay bankruptcy by using strategies that create the hope that they will become dependable in the future according to prospect theory these strategies work because creditors wish to avoid recognizing significant losses and thus take on more risk than they might otherwise assume

top managerial prestige and organizational bankruptcy this paper extends earlier work on an alternative view of bankruptcy suggesting that bankruptcy occurs when creditors withdraw then support from a firm s top management team it further proposes that support for the top team depends upon the team s prestige five characteristics measuring the relative status of top teams were tested for their association with bankruptcy three of the characteristics focused on items commonly associated with membership in economic elites elite educational backgrounds board memberships and previous employment as officers in other corporations the fourth and fifth characteristics focused on membership in political and military elites the results indicated that political and board connections were negatively associated with bankruptcy in the year of failure even when financial factors and cooptive board linkages were controlled the results also showed that failing firms attempted to improve their managerial prestige three to four years before they failed they were how

mutual monitoring and corporate governance abstract mutual monitoring in a well structured authority system can mitigate the agency problem i empirically examine whether the number two executive in a firm if given authority incentive and channels for communication and influence is able to monitor and constrain the potentially self interested ceo i find strong evidence that 1 measures of the presence and extent of mutual monitoring from the no 2 executive are positively related to future firm value tobin s q 2 the beneficial effect is more pronounced for firms with stronger incentives for the no 2 to monitor and with higher information asymmetry between the boards and the ceos and 3 mutual monitoring is a substitute for other governance mechanisms the results suggest that mutual monitoring provides important checks and balances on ceo power

using referenda to improve targeting and decrease costs of conditional cash transfers cost effective allocation of conditional cash transfers cct requires identifying recipients with low opportunity costs who might change behavior this paper develops a low cost approach for improving program implementation by using a stated preference referendum style survey question to calculate willingness to accept wta for cct contracts this is illustrated in the context of mexico s payments for ecosystem services program with the paper finding that the estimated social cost based on wta is substantially lower than actual payments simulation of three geographic targeting approaches shows that joint selection using deforestation risk and wta could increase program impact under the same budget the paper also simulates modified payment schedules based on predicted wta and demonstrates that these could reduce program cost

do local officials know something we don t decentralization of targeted transfers in albania abstract albania provides a small amount of social assistance to nearly 20 of its population through a system which allows a degree of community discretion in determining distribution this study indicates that relative to other safety net programs in low income countries social assistance in albania is fairly well targeted to the poor moreover the poverty targeting exceeds that which could be expected on the basis of proxy indicators of targeting alone communes appear to be using local information unlikely to be obtained on the basis of a questionnaire or formula this remains the case conditional on the level of funding allocated from the central government

targeting the poor evidence from a field experiment in indonesia the brief summarizes the targeting the poor evidence from a field experiment in indonesia for the period december 2008 january 2009 this paper reports an experiment in 640 indonesian villages on three approaches to target the poor proxy means tests pmt where assets are used to predict consumption community targeting where villagers rank everyone from richest to poorest and a hybrid defining poverty based on ppp 2 per capita consumption community targeting and the hybrid perform somewhat worse in identifying the poor than pmt though not by enough to significantly affect poverty outcomes for a typical program elite capture does not explain these results instead communities appear to apply a different concept of poverty

succession planning vs agency theory a test of harris and helfat s interpretation of plurality announcement market returns in this note we respond to harris and helfat s 1998 reinterpretation of the results in worrell nemec and davidson 1997 harris and helfat argued that the negative stock market response associated with plurality announcements could be the result of inadequate corporate succession planning rather than with the agency cost explanation our results here show that duality and plurality announcements do not hurt shareholder wealth as long as there is an heir apparent and therefore are more consistent with the succession planning explanation than with agency theory copyright 2001 john wiley sons ltd

do low income housing subsidies increase the occupied housing stock abstract a necessary condition for justifying a policy such as subsidized low income housing either via tenant based rental assistance or construction of public or private projects is that it has a real effect on market outcomes in this paper we examine one aspect of the real effect of subsidized housing does it increase the housing stock if subsidized housing raises the quantity of occupied housing per capita either more people are finding housing or they are being housed less densely on the other hand if subsidized housing merely crowds out equivalent quality low income housing that otherwise would have been provided by the private sector the housing policy may have little real effect on housing consumption using both census place and msa level data from the decennial census and from the department of housing and urban development we ask whether housing markets with more subsidized housing also have more total housing after accounting for housing demand we find that government financed units raise the total number of units in a market although on average one government subsidized unit adds only one third to one half of a unit to the total housing stock there is less crowd out in more populous markets and more crowd out in places where there is less excess demand for subsidized housing as measured by the number of government financed units per eligible person tenant based housing programs such as section 8 certificates and vouchers seem to be more effective than project based programs at targeting subsidized housing units to people who otherwise would not have their own

agency models in different stages of ceo tenure the effects of stock options and board independence on r d investment this study examines how r d investment is shaped by governance devices combining the two agency models of limited competence and managerial opportunism it suggests that governance devices exert differing effects in early vs later stages of ceo tenure early in ceo tenure r d investment is reduced by stock options and board independence whereas in later stages these effects reverse r d investment is enhanced by stock options and board independence an empirical test on a sample of u s companies provides support for the hypothesized effects for policy makers this study implies that r d investment can be enhanced by setting rules and standards of good governance that take into account ceo time in office and firm context

direct conservation payments in the brazilian amazon scope and equity implications abstract this article looks into the scope and equity implications of applying payments for environmental services pes as a redd implementation mechanism in the brazilian amazon we establish a set of economic and institutional preconditions for pes to become a feasible and cost effective conservation mechanism we proceed with a macro scale spatial analysis and overlay of opportunity costs deforestation patterns carbon services and land tenure in order to assess where these conditions hold we then screen how the benefits of potential pes schemes might be distributed across different socioeconomic groups of service providers in different land tenure categories our economic quantitative analysis though sensitive to documented assumptions suggests that under current carbon prices the economic preconditions are in place to pay for avoided deforestation in over half of threatened forests over the next decade unfortunately the same optimism does not apply to institutional preconditions land grabbing insecure tenure overlapping claims and lacking information on private tenure constitute real medium term impediments to pes if payments were to accrue to current landholders regardless of current tenure insecurities large landowners who account for about 80 of all deforestation would reap the highest benefits though per capita benefits other tenure categories are also high schemes that closely align payments with opportunity costs are preferable for cost effectiveness and not necessarily more inequitable in outcomes essentially pes systems cannot substitute command and control measures the former depend on the latter for basic governance systems to secure effective rights of exclusion which land stewards essentially need in order to become reliable service providers

benefits and costs of deforestation by smallholders implications for forest conservation and climate policy deforestation is a leading cause of biodiversity loss and an important source of global carbon emissions this means that there are important synergies between climate policy and conservation policy the highest rates of deforestation occur in tropical countries where much of the land at the forest frontier is managed informally by smallholders and where governance systems tend to be weak these features must be considered when designing policies to reduce emissions from deforestation such as redd deforestation is often accompanied by fires that release large amounts of carbon dioxide these emissions are especially high in the case of peatlands which contain thick layers of carbon rich matter in this paper we derive marginal abatement cost mac curves using data from a farmer survey in sumatra where rates of peatland deforestation are high comparing these results with farmers stated willingness to accept payment not to clear forest to establish oil palm suggests that redd policies may be more expensive than mac estimates suggest the extent to which this is true depends on the types of soils being deforested

making conditional cash transfer programs more efficient designing for maximum effect of the conditionality conditional cash transfer programs are now used extensively to encourage poor parents to increase investments in their children s human capital these programs can be large and expensive motivating a quest for greater efficiency through increased impact of the programs imposed conditions on human capital formation this requires designing the programs targeting and calibration rules specifically to achieve this result using data from the progresa randomized experiment in mexico this article shows that large efficiency gains can be achieved by taking into account how much the probability of a child s enrollment is affected by a conditional transfer rules for targeting and calibration can be made easy to implement by selecting indicators that are simple observable and verifiable and that cannot be manipulated by beneficiaries the mexico case shows that these efficiency gains can be achieved without increasing inequality among poor households

management and ownership effects evidence from five countries despite the growing recognition in the corporate governance literature that the relationship between ownership concentration and profitability is context dependent this issue has not yet been subjected to direct empirical investigation using a single cross national sample this study empirically examines the ownership concentration performance relationship across the nations of canada france germany the united kingdom and the united states essentially we argue that the correlation if any between ownership concentration and firm profitability differs across countries in a systematic way determined by the national system of corporate governance results indicate that important and statistically significant differences do in fact exist across the countries studied 1998 john wiley sons ltd

global standards and ethical stock indexes the case of the dow jones sustainability stoxx index the increased scrutiny of investors regarding the non financial aspects of corporate performance has placed portfolio managers in the position of having to weigh the benefits of holding the market against the cost of having positions in companies that are subsequently found to have questionable business practices the availability of stock indexes based on sustainability screening makes increasingly viable for institutional investors the transition to a portfolio based on a socially responsible investment sri benchmark at relatively low cost the increasing share of socially responsible investments may play a role in providing incentives towards a continuous upgrading of sustainability standards to the extent that their performance is not systematically inferior to that of the other funds this article examines whether these incentives have been so far detectable with particular reference to the dow jones sustainability stoxx index djssi that focuses on the european corporations with the highest csr scores among those included in the dow jones stoxx 600 index the aim of the article is twofold first we analyse the performance of the djssi over the period 2001 2006 compared to that of the surrogate complementary index sci a new benchmark that includes only the components of the dj stoxx 600 that do not belong to the ethical index to evaluate more correctly the size of possible divergent performances second we perform an event study on the same data set to analyse whether the stock market evaluation reacts to the inclusion deletion in the djssi in both cases the results suggest that the evaluation of the csr performance of a firm is a significant criterion for asset allocation activities

a rose by any other name are family firms named after their founding families rewarded more for their new product introductions the authors explore the relation between the way different family firms are named and the shareholder value impact of these firms new product introductions using an event study of 1 294 product introduction announcements of 107 publicly listed u s family firms the authors find that the presence of the founding family s name as part of a family firm s name acts as a valuable firm resource increasing the abnormal stock returns surrounding the firm s new product introductions superior returns to family named firms new product introductions are partially mediated by these firms history of ethical product related behavior family named firms particularly those with corporate branding and those wherein a founding family member holds the ceo or chairman position are more likely to exhibit a history of avoiding such product related controversies as product safety issues and deceptive advertising the authors highlight the managerial and theoretical contributions of this research

decentralized targeting of an antipoverty program abstract developing country governments often delegate authority over the targeting of antipoverty programs to community organizations while retaining control over how much goes to each community we offer a theoretical characterization of the information structure in such programs and the interconnected behavior of the various players our model motivates an econometric specification for explaining distributional outcomes results for bangladesh s food for education ffe program indicate that within village targeting improved with program size lower land inequality less remoteness fewer shocks and less private redistribution there is no sign that the center took account of village attributes conducive to reaching the poor

anomalies in security returns and the specification of the market model we examine the hypothesis originally advanced by roll 12 that observed anomalies in excess returns can be explained by misspecification of the market model used to estimate systematic risk we find substantial misspecifications in the model systematically related to size and period of listing of the securities in question there is some evidence that these misspecifications are associated with systemic biases in measured betas used to construct excess returns

geographical targeting for poverty alleviation an introduction to the special issue in the face of rising public deficits and shrinking public resources geographical targeting may be a viable way to allocate resources for poverty alleviation in developing countries efficiency can be increased and leakage to the non poor reduced substantially by targeting increasingly smaller areas this article and more generally the symposium on geographical targeting for poverty alleviation proposes several techniques for augmenting data to produce more detailed poverty maps it focuses on practical considerations in the design of geographically targeted poverty alleviation programs in particular it assesses the advantages and disadvantages of geographical targeting and describes how geographic information systems can be applied to improve poverty mapping

apprentice departure and demotion an examination of the three types of ceo board chair separation past research has consistently shown that separation of ceo and board chair roles has no systematic effect on firm performance in this study we introduce the different forms of such separation apprentice departure and demotion in a study of standard poor s s p 1500 and fortune 1000 firms we find that separation of the two leadership roles positively impacts future firm performance when current performance is poor but negatively impacts future firm performance when current performance is high we find that this effect is most dramatic for demotion separations finally we test theory about the permanency of ceo board chair separation our results show that the different types of ceo board chair separation have very distinct consequences abstract from author

s p 500 index additions and earnings expectations stock price increases associated with addition to the s p 500 index have been interpreted as evidence that demand curves for stocks slope downward a key premise underlying this interpretation is that index inclusion provides no new information about companies future prospects we examine this premise by analyzing analysts earnings per share eps forecasts around index inclusion and by comparing postinclusion realized earnings to preinclusion forecasts relative to benchmark companies companies newly added to the index experience signi cant increases in eps forecasts and signi cant improvements in realized earnings these results indicate that s p index inclusion is not an information free event studies that examine the prices of common stocks when they become included in the standard poor s s p 500 index have appeared regularly in leading nance journals since 1986 fascination with the eiect of s p index inclusion on stock prices appears to stem from the possibility that inclusion in the index is an information free eventfinformation free in the sense that s p makes no claim that inclusion represents an endorsement of the newly included stock s future prospects 1 indeed s p makes an a rmative claim to the contrary company

efficient estimation methods for closed ended contingent valuation surveys closed ended contingent valuation surveys can be very useful in the evaluation of nonmarket resources respondents merely state whether they would accept or reject a hypothetical threshold amount either as payment for giving up access to the resource or as a fee for its use the authors develop a maximum likelihood procedure which exploits the variation in the threshold values to allow direct and separate point estimates of regression like slope coefficients and error standard deviations without truncation bias their illustration uses data from a survey of recreational fisherman to examine factors which influence individuals willingness to pay copyright 1987 by mit press

price and volume effects associated with changes in the s p 500 list new evidence for the existence of price pressures attempts to identify price pressures caused by large transactions may be inconclusive if the transactions convey new information to the market this problem is addressed in an examination of prices and volume surrounding changes in the composition of the s p 500 since these changes cause some investors to adjust their holdings of the affected securities and since it is unlikely that the changes convey information about the future prospects of these securities they provide an excellent opportunity to study price pressures the results are consistent with the price pressure hypothesis immediately after an addition is announced prices increase by more than 3 percent this increase is nearly fully reversed after 2 weeks the efficient market hypothesis emh predicts that security prices reflect all publicly available information therefore one corollary of the emh is that you can sell or buy large blocks of stock at close to the market price as long as you can convince other investors that you have no private information 1 this statement assumes that securities are near perfect substitutes for each other if so the excess demand for a single security will be very elastic and the sale or purchase of a large number of shares will have no impact on price in contrast to the emh scholes 8 kraus and stoll 5 hess and frost 4 and others propose two hypotheses which predict that a large stock sale purchase will cause the price to decrease increase even if no new information is associated with the transaction the imperfect substitutes hypothesis ish also known as the distribution effect hypothesis assumes that securities are not close substitutes for each other and hence that long term demand is less than perfectly elastic under this hypothesis equilibrium prices change when demand curves shift to eliminate excess demand price reversals are not expected because the new price reflects a new equilibrium distribution of security holders the price pressure hypothesis pph assumes that investors who accommodate demand shifts must be compensated for the transaction costs and portfolio risks that they bear when they agree to immediately buy or sell securities which they otherwise would not trade these passive suppliers of liquidity are attracted by immediate price drops rises associated with large sales purchases they are compensated for their liquidity service when prices rise drop to their fullinformation levels the pph like the emh assumes that long run demand is

market reactions to corporate environmental performance related events a meta analytic consolidation of the empirical evidence research on the relationship between corporate environmental performance cep and corporate financial performance cfp has consistently grown and is gaining widespread attention given the vast body of cep cfp studies recently scholars have begun to take stock of the cumulative results however no study so far has meta analyzed the findings yielded by event studies assessing the stock market reactions to corporate environmental performance related events cep related events this paper sets out to close this gap by synthesizing previous empirical results regarding the stock market impact of positive and negative cep related events results indicate a positive relationship across studies in terms of positive market reactions to positive events and negative reactions to negative events furthermore the findings show that the market reactions are stronger for negative events than for positive events i e asymmetry in the stock market reaction finally this study examines whether methodological artifacts i e differences in the study designs may explain the differences in the findings of the analyzed event studies

the price response to s p 500 index additions and deletions evidence of asymmetry and a new explanation we study the price effects of changes to the s p 500 index and document an asymmetric price response there is a permanent increase in the price of added firms but no permanent decline for deleted firms these results are at odds with extant explanations of the effects of index changes that imply a symmetric price response to additions and deletions a possible explanation for asymmetric price effects arises from the changes in investor awareness results from our empirical tests support the thesis that changes in investor awareness contribute to the asymmetric price effects of s p 500 index additions and deletions the long held assumption that stocks have perfect substitutes and the perfect elasticity of demand that follows from it is central to modern finance theory if securities have almost perfectly elastic demand then any supply or demand shocks that are devoid of information should have no effect on the prevailing price early empirical research on whether price changes occur in the absence of new information focused on block trades equity issues and stock splits but was unable to exclude information effects around these events since there is no obvious reason to believe ex ante that index changes contain new information they constitute a natural framework for testing whether stocks have almost perfectly elastic or horizontal demand curves a stock s excess return around such changes could be consistent with a downward sloping demand curve with the advent of indexed mutual funds in 1976 and the public announcement of s p index changes in the same year there is much evidence that such announcements are accompanied by an increase in price for firms added to the index if stocks have a short term downward sloping demand curve the price should be momentarily affected by a demand shock due to indexing but that effect

the effectiveness of payments for environmental services we adopt a theory based approach to synthesize research on the effectiveness of payments for environmental services in achieving environmental objectives and socio economic co benefits in varying contexts our theory of change builds on established conceptual models of impact pathways and highlights the role of 1 contextual dimensions e g political institutional and socio economic conditions spatial heterogeneity in environmental service values and provision costs and interactions with pre existing policies and 2 scheme design e g payment type and level contract length targeting and differentiation of payments in determining environmental and socio economic outcomes to shed light on the overall effectiveness of payment schemes and its determinants we review counterfactual based empirical evaluations comparative analyses of case studies and meta analyses our review suggests that program effectiveness often lags behind the expectations of early theorists however we also find that theory has advanced sufficiently to identify common reasons for why payment schemes fail or succeed moreover payment schemes are often rolled out along with other policy instruments in so called policy mixes advances in theory and evaluation research are needed to improve our understanding of how such policy mixes interact with the targeted social ecological systems 2017

do demand curves for stocks slope down since september 1976 stocks newly included into the standard and poor s 500 index have earned a significant positive abnormal return at the announcement of the inclusion this return does not disappear for at least ten days after the inclusion the returns are positively related to measures of buying by index funds consistent with the hypothesis that demand curves for stocks slope down the returns are not related to s p s bond ratings which is inconsistent with a plausible version of the hypothesis that inclusion is a certification of the quality of the stock

how does the market value corporate sustainability performance this study provides empirical evidence on how corporate sustainability performance csp as proxied by membership of the dow jones sustainability index is reflected in the market value of equity using a theoretical framework combining institutional perspectives stakeholder theory and resource based perspectives we develop a set of hypotheses that relate the market value of equity to csp for a sample of north american firms our preliminary results show that csp has significant explanatory power for stock prices over the traditional summary accounting measures such as earnings and book value of equity however further analyses suggest that we should not focus on corporate sustainability itself our findings suggest that what investors really do is to penalize large profitable firms with low level of csp firms with incentives to develop a high level of csp not engaging on such strategy are thus penalized by the market

the effect of additions to or deletions from the tse 300 index on canadian share prices in this paper we examine shares that have been added to or deleted from the tse 300 index to determine whether abnormal price movements have occurred we apply the dummy variable approach to event study methodology and adjust the estimated standard errors for arbitrary heteroscedasticity and clustering of events we also use a non parametric method of inference like authors of u s studies we find that the market reacts positively to inclusion and negatively to deletion albeit not significantly in the latter case the information content of inclusion does not account for the entire share price response lending support to the hypothesis of increased purchases by index funds jel classification g14 ce texte examine les titres qui ont ete ajoutes ou soustraits de l indice tse 300 pour determiner si des mouvements anormaux de prix s en sont suivis on utilise l approche des variables fictives dans le cadre d une methodologie qui etudie l impact d evenements et on ajuste les erreurs standards pour tenir compte de l heteroskedasticite arbitraire et de l agglomeration d evenements on utilise aussi une methode non parametrique d inference comme dans des etudes americaines du meme type on decouvre que les marche reagit positivement a l inclusion et negativement a la soustraction d un titre mais que l effet n est pas significatif dans ce dernier cas le contenu informationnel de l inclusion n explique pas entierement le mouvement dans le prix du titre ce qui apporte un support a l hypothese de l impact des achats accrus par des fonds indexes
