what drives corporate social performance the role of nation level institutions based on whitley s national business systems nbs institutional framework we theorize about and empirically investigate the impact of nation level institutions on firms corporate social performance csp using a sample of firms from 42 countries spanning seven years we construct an annual composite csp index for each firm based on social and environmental metrics we find that the political system followed by the labor and education system and the cultural system are the most important nbs categories of institutions that impact csp interestingly the financial system appears to have a relatively less significant impact we discuss implications for research practice and policymaking

auctions of heterogeneous objects abstract simultaneous sealed bid auctions of heterogeneous objects are analyzed each bidder s reservation value for an object depends upon the other objects he obtains bidders reservation values are common knowledge in simultaneous first price auctions the set of walrasian equilibrium allocations contains the set of pure strategy nash equilibrium allocations which in turn contains the set of strict walrasian equilibrium allocations hence pure strategy nash equilibria when they exist are efficient mixed strategy nash equilibria may be inefficient in simultaneous second price auctions any efficient allocation can be implemented as a pure strategy nash equilibrium outcome if a walrasian equilibrium exists journal of economic literature classification numbers d44 d51

integration of spatial markets studies of spatial market integration draw their implications from a theory which assumes that there are no intraregional transport costs an alternative theory is offered based on the assumptions that buyers and sellers are spatially dispersed and intraregional transport costs are significant this implies that the market is a linked oligopoly or oligopsony and that market integration tests are tests of alternative oligopoly price formation processes for example collusive basing point pricing produces results typically assumed to imply efficiently integrated markets while competitive fob pricing does not the theoretical implications are illustrated with an analysis of hog prices in canada

fund loyalty among socially responsible investors the importance of the economic and ethical domains the corporate social responsibility literature has emphasized the importance of both economic and ethical domains of corporate behavior analyzing unprecedented survey data from investors in a socially responsible sr mutual fund this article considers how economic and ethical concerns shape shareholder investment behavior in particular this article analyzes levels of investor fund loyalty defined as the continued investment in a mutual fund despite the belief that one is earning a lower return on investment building upon existing research that shows sr fund assets are more stable than conventional fund assets this article leverages within respondent comparisons to clarify that dual investors i e those who invest in both sr and conventional funds are more loyal to their sr fund than to their conventional fund this suggests that a corporation s ethical behavior attracts more patient investment capital an important consideration for any corporation that is deciding to what degree it should engage in corporate social responsibility in addition this article empirically demonstrates that economic motivations reduce sr fund loyalty and that ethical motivations induce sr fund loyalty this evidence that ethical motivation is associated with fund loyalty advances research on morality in the market by yielding empirical evidence to a largely theoretical debate

socially responsible investors and the microentrepreneur a canadian case socially responsible investors buy financial securities with two goals to make a market based return and to make companies act in a more socially responsible way most research on socially responsible investment deals with investing in stocks traded on major exchanges we add the case of loaning small amounts of funds to microentrepreneurs through a discussion of a particular case the case is that of calmeadow which in conjunction with the royal bank of canada set up a microlending project in rural nova scotia canada using hirschman s analysis of exit and voice we show that while socially responsible investors may make market based returns for their investments in stocks traded on major exchanges they have no effect on corporate behaviour because their action consists of exit and they are easily replaced by other investors they attain their first goal but not their second on the other hand in the calmeadow royal bank of canada case we see that those who lend money to microenterprises can more easily use voice the relative power difference between the lender and the microentrepreneur enables the lender to make the microentrepreneur act in a more socially responsible way although only marginally but because of the market imperfections existing in this case the very high transactions costs associated with administering small loans the lender concluded it could not attain a market rate of return in this case then the lender attained its second goal but not its first

on favoritism in auctions with entry abstract we examine the problem of endogenous entry in a single unit auction when the seller s welfare depends positively on the utility of a subset of potential bidders we show that unless the seller values those bidders welfare more than her own private utility a nondiscriminatory auction is optimal

putting sustainable investing into practice a governance framework for pension funds this article presents a framework intended to provide pension funds with practical guidance for the successful implementation of a sustainable investing strategy the framework is developed with respect to the uk and us pension funds as these share certain common legal characteristics and focuses on the changes that pension funds adopting such a strategy should make to their investment strategies and governance particularly through the formulation and articulation of clear investment mission and strong investment beliefs the article proceeds with a review of socially responsible investment sri and more recent responsible investment ri literature in the context of growing public awareness but not necessarily understanding of the concept of sustainability literature review of sri field sri ri and sustainable investing section it then examines the literature on pension fund governance arguing the need for more detailed practical guidance for funds moving towards sustainable investing especially for those implementing a sustainable investing strategy anglo american pension fund governance section it presents the framework for the practical implementation of sustainable investing in the sustainable investing framework section finally we review the relevant anglo american legal backdrop outlining how pension funds adopting our framework should approach their fiduciary obligations and then discussing potential regulatory enablers of sustainable investment legal context barriers to and enablers of sustainable investing section

the drivers of responsible investment the case of european pension funds we investigate what drives responsible investment of european pension funds pension funds are institutional investors who assure the income of part of the population for a long period of time increasingly stakeholders hold pension funds accountable for the non financial consequences of their investments and many funds have engaged in responsible investing however it appears that there is a wide difference between pension funds in this respect we investigate what determines pension funds responsible investments on the basis of a survey of more than 250 pension funds in 15 european countries in 2010 we use multinomial logistic regression and find that especially legal origin of the country ownership of the pension fund and fund size related variables are to be associated with pension funds responsible investment for fund size we establish a curvilinear relationship especially the smallest and largest pension funds in the sample tend to engage with responsible investing

finance as a driver of corporate social responsibility finance is grease to the economy therefore we assume that it may affect corporate social responsibility csr and the sustainability of economic development too this paper discusses the transmission mechanisms between finance and sustainability we find that there is no simple one to one relationship between financial development and sustainable development but there are various often indirect linkages it appears that most of the literature concentrates on the role of public shareholders when it comes to changing corporate policy and performance in a more sustainable direction however this focus neglects the potential impact of the credit channel and private equity on a firm s non financial policies and performance these very powerful mechanisms can govern business policies and practices therefore there appears to be much more scope for finance to promote socially and environmentally desirable activities and to discourage detrimental activities than has been acknowledged in the academic literature so far

investment incentives in procurement auctions this paper investigates firms incentives to invest in cost reduction in the first price sealed bid auction a format largely used for procurement two central features of the model are that we allow firms to be heterogeneous and that investment is observable we find that firms will tend to underinvest in cost reduction because they anticipate fiercer head on competition using the second price auction as a benchmark we also find that the first price auction will elicit less investment from market participants and that this is socially inefficient these results have implications for market design when investment is important different market institutions provide different incentives for firms to reduce costs acquire information expand and so on in short to undertake any activity that affects their competitive positions accordingly the performance of these market institutions should be judged not only from a static perspective taking firms competitive positions as given but also from a dynamic perspective auction markets are a natural competitive environment to study because there is a clear sense in which we can design such markets by choosing appropriate rules for competition in this paper we study how the first price auction fpa a format commonly used for procurement affects firms incentives to invest in cost reduction many procurement markets are characterized by a small number of participants heterogeneity among firms and low rates of turnover therefore it is interesting to investigate to what extent the format used for the auction contributes to these characteristics the basic ingredients of our model are as follows there are n firms and one of them has the opportunity prior to the auction to make an investment we model this investment as an improvement in the ex ante distribution of costs for this firm the main question we ask is what are the firm s incentives to invest given that this investment is observed by its competitors clearly the benefits of such investment depend on how the firm s competitors react in other words to determine the firm s incentive to invest we need to compare the equilibrium at the procurement stage if it makes this investment and if it does not in section 3 we derive new comparative statics results for the fpa we find that after the investment the investor s opponents will bid collectively more aggressively this result holds generally when there are only two bidders or when the investor s opponents are symmetric proposition 1 otherwise a sufficient condition is that investment changes market leadership proposition 2 in the language of industrial organization investment has a negative strategic effect in the fpa this erodes 1

corporate social responsibility in the international banking industry this article aims at providing a framework to assess corporate social responsibility with international banks currently it is mainly rating institutions like eiris and kld that provide information about firms social conduct and performance however this is costly information and it is not clear how the rating institutions arrive at their conclusion we develop a framework to assess the social responsibility of internationally operating banks we apply this framework to more than 30 institutions and find significant differences among individual banks countries and regions furthermore it appears that social responsibility of these banks has significantly improved between 2000 and 2005

optimal auctions with information acquisition this paper studies optimal auction design in a private value setting with endogenous information acquisition first we develop a general framework for modeling information acquisition when a seller wants to sell an object to one of several potential buyers who can each gather information about their valuations prior to participation we then show that under certain conditions standard auctions with a reserve price remain optimal but the optimal reserve price lies between the mean valuation and the standard reserve price in myerson 1981 we provide sucient conditions under which the value of information to the seller is positive and also characterize the necessary and sucient conditions under which equilibrium information acquisition in private value auctions is socially excessive the key to the analysis is the insight that buyer incentives to acquire information become stronger as the reserve price moves toward the mean valuation

a puzzle in sri the investor and the judge as socially responsible investment sri enters the mainstream of professional and institutional investment practice some perplexities arise some sri market participants are well schooled in finance but are hesitative as to how to apply non financial criteria in the management of portfolios governments too are giving sri more attention and in some countries are discussion whether and how to regulate the sri market advocacy groups are targeting sri projects through media campaigns using political discourse many of the pertinent questions that come with these perplexities are of the philosophical or ethical type and concern legitimisation demarcation of responsibilities interpretation of norms and policy formulation the inclusion of non financial criteria into investment decision making leads to a puzzle in sri for which this article offers a solution the puzzle arises when the day to day implementation of an sri policy coincides with the process of administering justice three questions make up that puzzle 1 what should an investor do when allegations arise about a corporation 2 what should an investor do when a corporation is brought before a court 3 what should an investor do when a corporation is found guilty by a court this article argues by distinguishing between the rationality of the investor and that of the judge that allegations court cases or court verdicts should not be reasons to disinvest from a corporation this article offers examples from investor practice and points out in which way allegations court cases and court verdicts make sense for investor behaviour

the influence of primary study characteristics on the performance differential between socially responsible and conventional investment funds a meta analysis empirical studies which analyze the performance of socially responsible investment sri funds relative to conventional funds find contradictory results the aim of this paper is to investigate with the help of a meta analysis how selected primary study characteristics influence the probability of a significant under or outperformance of sri funds compared with conventional funds 25 studies with more than 500 observations are included in the meta analysis the results of this paper suggest that the consideration of the survivorship bias in a study increases decreases the probability of a significant outperformance underperformance of sri funds relative to conventional funds the focus on united states us sri funds increases decreases the probability of a significant outperformance underperformance too the time period influences the probability of a significant under and outperformance of sri funds as well but based on the results of this paper it is not possible to draw general conclusions on this variable

no trade in second price auctions with entry costs and secret reserve prices we consider a second price private value auction in the presence of an exogenous participation cost and a secret reserve price endogenously set by the seller we show that if the entry cost is strictly positive the only equilibrium outcome is that the seller chooses a reserve price that deters entry and no buyer enters

exploring factors that influence social retail investors decisions evidence from desjardins fund most studies on the choices motivations and behavior of investors consist of segmentations focused on socio demographic characteristics such as age income education level etc such approaches seem to simplify even mutilate reality by aggregating data about observable variables and considering investors as homogeneous groups these perspectives are inspired by a scientific approach that consists of separating in order to better understand the observed phenomena by considering individual as a homo economicus that is to say a rational and autonomous individual who makes decisions motivated by material gains these studies fail to recognize all the complexity that shapes human behavior this paper argues that to understand the behavior and choices of investors in regards to socially responsible investing sri we must consider social investors as complex individuals in addition we should take into account influence that the institution may exercise throughout the role of advisors and sri promotion strategies our research builds on a multidimensional approach that explores to what extent demographic environmental social and governance esg issues the trade offs between financial return and social values the attitudes and the role of the institution throughout the role of the advisor and sri promotion strategies influence the decisions of individual social investors moreover it adopts a more open approach by exploring the characteristics and behaviors of individual social investors in relation to those of conventional investors our research provides evidence from the desjardins fund qualitative and quantitative data gathered by desjardins from online surveys are subjected to bivariate and multivariate analyses and are complimented by ten semi structured interviews with managers analysts and advisors who provided further insight into sri investment behavior and choice the results show that while demographic characteristics still remain important in understanding the behavior and attitudes of social investors it is their social values esg issues financial return considerations and the role played by the institution in mediating investment decisions that are significantly associated with sri portfolios our research highlights the complexity surrounding the phenomenon of sri and has several implications both in terms of theory and practice

contracts with endogenous information abstract i study covert information acquisition and reporting in a principal agent problem allowing for general technologies of information acquisition when posteriors satisfy two dimensional versions of the standard first order stochastic dominance and concavity convexity of the distribution function conditions a first order approach is justified under the same conditions informativeness and riskiness of reports are equivalent high powered contracts that make the agent s informational rents more risky are used to increase incentives for information acquisition insensitive contracts are used to reduce incentives for information gathering the value of information to the agent is always positive the value of information to the principal is ambiguous

morals markets and sustainable investments a qualitative study of champions sustainable investment si which integrates social environmental and ethical issues has grown from a niche market of individual ethical investors to embrace institutional investors e g pension funds resulting in 764 billion in assets under management in the uk alone eurosif 2008 european sri study 2008 eurosif paris explaining this growth is complex involving shifts in personal and collective values reactions to corporate scandals scientific and media pronouncements about climate change government initiatives responses from financial markets and the influence of si innovators in the city of london the article examines the influence of human agency through interviews with 14 si champions who have variously been responsible for launching si funds and changing investment processes and organisational structures in order to enhance si interviewees were asked about their motivations and persuasive strategies the obstacles they faced and how they overcame them as well as broader implications of si for financial markets the following key categories inform the results and the discussion values conservatism antipathy and incredulity optimism and sympathy from insiders the social and political context the business case organisational constraints inappropriate forms of remuneration short termism the nature of capitalism three discourses were also identified the first is the necessity to make a business case for si the second is the benefits that si can bring to the quest of overcoming short termism the third is a belief that for si to have a significant influence greater government intervention is required

optimal bidding in auctions from a game theory perspective abstract the game theoretic perspective in auction bidding has provided a powerful normative framework for the analysis of auctions and it has generated an impressive volume of research contributions tracing this research we review key recent advances which have greatly expanded our understanding of the operation of auctions and produced a more accurate analysis of mechanism design and optimal bidding we follow various experimental studies which have shown that the predictive power of auction theory remains in many cases limited for this reason we concentrate on research themes which enhance the applicability of auction theory leading to more realistic descriptions of bidding behaviors we identify important innovations which expand the environment of auction bidding and carry us beyond rational decision making we conclude providing directions of future research and discussing their implications

auctions and information acquisition sealed bid or dynamic formats the value of an asset is generally not known a priori and it requires costly investments to be discovered in such contexts with endogenous information acquisition which selling procedure generates more revenues we show that dynamic formats such as ascending price or multistage auctions perform better than their static counterpart this is because dynamic formats allow bidders to observe the number of competitors left throughout the selling procedure thus even if competition appears strong ex ante it may turn out to be weak along the dynamic format thereby making the option to acquire information valuable this very possibility also induces the bidders to stay longer in the auction just to learn about the state of competition both effects boost revenues and our analysis provides a rationale for using dynamic formats rather than sealed bid ones

forecasting vector autoregressions with bayesian priors the paper explores the justification for and application of bayesian priors in forecasting a vector autoregression a nonsymmetric random walk prior outperforms three alternative time series representations in forecasting five series of the u s hog market

evaluating the integration of contiguous discontinuous markets this paper applies the concepts of structural models of markets market integration and market discontinuity to show that discontinuous markets alter the integration characteristics of continuous markets when analyzing systems of contiguous markets some of which are discontinuous it appears that the continuous markets are less well integrated when the discontinuous markets are operating than when they are not operating

ex ante efficient mechanism with private entry costs this paper studies ex ante efficient resource allocation mechanism in an environment where agents endowed with their private values must incur private entry costs to participate due to the nature of this bidimensional screening problem and the difficulty in fully characterizing all implementable endogenous entries the domain of the related social planner s problem that is essential for establishing the existence of efficient mechanism needs to be carefully designed we find that a second price auction among the entrants with a reserve price equal to the seller s valuation is ex ante efficient and any ex ante efficient mechanism must be ex post efficient jel d44 d61 d82

does equity ownership matter for corporate social responsibility a literature review of theories and recent empirical findings based on the concept of shareholder primacy many scholars have argued that it is more important for businesses to earn profits for their shareholders than to provide benefits to society at large corporate social responsibility csr is often regarded as an investment that comes at the expense of shareholders in contrast research analyzing the connections between the equity ownership structure of a company and its level of csr engagement suggests that csr offers benefits to shareholders that go beyond direct financial returns from investments this study provides a comprehensive review and systematic assessment of theoretical considerations and approaches regarding different forms of equity ownership and their relationships to csr and it discusses the relevant benefits and motivations of shareholders the perceived value of these csr benefits varies among different types of shareholders as they assign unequal values to short term financial or to rather long term csr benefits based on a literature sample of 146 publications this review demonstrates central problems inherent in previous analyses given the ambiguous and partially contradictory findings of prior research this study identifies potential moderating influences that help clarify empirical evidence a contingency approach is suggested in future research as this can help resolve the problem of contradictory empirical findings and theoretical arguments

socially responsible investment and fiduciary duty putting the freshfields report into perspective a critical issue for the future growth and impact of socially responsible investment sri is whether institutional investors are legally permitted to engage in it in particular whether it is compatible with the fiduciary duties of trustees an ambitious report from the united nations environment programme s finance initiative unep fi commonly referred to as the freshfields report has recently given rise to considerable optimism on this issue among proponents of sri the present article puts the arguments of the freshfields report into some further both empirical and critical perspective however and suggests that its findings do not call for very much optimism the general argument is that while the understanding of fiduciary duty outlined by the freshfields report seems to allow institutional investors to at least sometimes take some social or environmental considerations into account the support it gives for sri is notably contingent and furthermore it rules out exactly the kind of sri which proponents of social responsibility and environmental sustainability should hold in highest regard proactive cases and socially effective investment strategies if sri is to become an important force for corporate social responsibility through its adoption by institutional investors then it is suggested that legal reform is needed

equilibria in first price auctions with participation costs this paper characterizes the equilibria of first price auctions with participation costs in the independent private values environment bidders use cutoff strategies to decide whether they will participate in the auction it is shown that when bidders are homogeneous there always exists a unique symmetric equilibrium and further there is no other equilibrium when valuation distribution functions are inelastic when distribution functions are elastic at the symmetric equilibrium there exists an asymmetric equilibrium inelasticity elasticity includes concavity convexity of distribution functions as a special case we find similar results when bidders are heterogeneous

an optimal voting procedure when voting is costly abstract we study optimal dynamic voting procedures when voting is costly for a highly stylized specification of our model with private values two alternatives and binary equally likely types we show the optimality of a voting procedure that combines two main elements i there is an arbitrarily chosen default decision and abstention is interpreted as a vote in favor of the default ii voting is sequential and is terminated when a supermajority requirement which declines over time is met we show the optimality of such a voting procedure by arguing that it is first best that is it maximizes welfare when equilibrium constraints are ignored and by showing that individual incentives and social welfare are sufficiently aligned to make a first best procedure incentive compatible we also provide counterexamples where no first best procedure is incentive compatible when voters binary types are not equally likely

tnc motives for signing international framework agreements a continuous bargaining model of stakeholder pressure over the past decade discussion has flourished among practitioners and academics regarding workers rights in developing countries the lack of enforcement of national labour laws and the limited protection of workers rights in developing countries have led workers rights representatives to attempt to establish transnational industrial relations systems to complement existing national systems in practice these attempts have mainly been operationalised in unilateral codes of conduct recently however negotiated international framework agreements ifas have been proposed as an alternative despite their growing importance few studies have empirically studied ifas this paper starts to fill this gap by studying why corporations adopt ifas based on a qualitative study of the process leading to the signing of a recent ifa the study s findings complement existing research into why corporations adopt ifas codes of conduct and csr policies by demonstrating that corporate motives can be linked to a desire to retain a trusting relationship with the labour union movement in addition the findings indicate that the discrete campaign model of stakeholder pressure dominant in previous research should be complemented by a continuous bargaining model of stakeholder pressure the paper concludes by discussing differences between these conceptual models of stakeholder pressure and avenues for future research

the heterogeneity of socially responsible investment many writers have commented on the heterogeneity of the socially responsible investment sri movement however few have actually tried to understand and explain it and even fewer have discussed whether the opposite standardisation is possible and desirable in this article we take a broader perspective on the issue of the heterogeneity of sri we distinguish between four levels on which heterogeneity can be found the terminological definitional strategic and practical whilst there is much talk about the definitional ambiguities of sri we suggest that there is actually some agreement on the definitional level there are at least three explanations which we suggest can account for the heterogeneity on the other levels cultural and ideological differences between different regions differences in values norms and ideology between various sri stakeholders and the market setting of sri discussing the implications of the three explanations for the sri market we suggest that there is reason to be sceptical about the possibilities of standardisation if not standardisation is imposed top down whether this kind of standardisation is desirable or not we argue depends on what the motives for it would be to the extent that standardisation may facilitate the mainstreaming of sri it could be a good thing but we entertain doubts about whether mainstreaming really requires standardisation

the dynamics of household beef consumption in cameroon abstract recent changes in economic conditions have introduced notable changes in household beef consumption patterns in cameroon while consumers are concerned about the short and long run effects of these factors on beef consumption habits policy makers are more worried about the appropriate period necessary for households to make complete adjustments in consumption since this information is vital for planning production static and dynamic demand frameworks involving the nerlovian partial adjustment pa model are used to capture the dynamic nature of beef consumption parameters maximum likelihood estimates of the pa model reveal that the conditioning variables explain 79 of the variation in beef consumption income previous consumption own price and prices of fish and pork are jointly important in explaining beef consumption habits beef is a normal good with pork and fish as substitutes and chicken as a complement long run price and income elasticities are greater than but not significantly different from their short run values suggesting that adjustment in consumption is fast with above 80 of the difference between actual and desired consumption being completed in about 2 years projections show that demand for beef will reach 109 620 t by the year 2000 giving an incremental total and per capita demand of 31 730 tons and 1 84 kg respectively

efficient investments in the implementation problem abstract this paper identifies a condition for an efficient social choice rule to be fully implementable when we take into account investment efficiency to do so we extend the standard implementation problem to include endogenous ex ante and ex post investments in our problem the social planner aims to achieve efficiency in every equilibrium of a dynamic game in which agents strategically make investments before and after playing the mechanism our main theorem shows that a novel condition commitment proofness is sufficient and necessary for an efficient social choice rule to be implementable in subgame perfect equilibria the availability of ex post investments is crucial in our model there is no social choice rule that is efficient and implementable in subgame perfect equilibria without ex post investments we also show that our positive result continues to hold in the incomplete information setting

the corporate social responsibility of pharmaceutical product recalls an empirical examination of u s and u k markets the pressure on companies to practice corporate social responsibility csr has gained momentum in recent times as a means of sustaining competitive advantage in business the pharmaceutical industry has been acutely affected by this trend while pharmaceutical product recalls have become rampant and increased dramatically in recent years no comprehensive study has been conducted to study the effects of announcements of recalls on the shareholder returns of pharmaceutical companies as product recalls could significantly damage a company s reputation profitability and brand integrity this paper investigates the effect on shareholder wealth and the extent to which the adoption of csr practices by pharmaceutical companies in the united kingdom u k and the united states u s the two largest markets for pharmaceutical products in the world affected market reactions surrounding product recall announcements the analysis of product recall announcements from 1998 to 2004 compiled from the pharmaceutical journal and u s food and drug administration enforcement reports revealed marked differences in the way market participants in the two countries responded to news of product recalls u s investors penalised firms according to the severity of product defects while u k investors were indifferent while u k investors rewarded product recalls by firms which were not usually csr active u s investors punished non csr active firms that performed recalls these observations could pose strategic challenges to pharmaceutical firms operating in both countries

causality tests in livestock markets bivariate time series models and related topics of exogeneity and granger causal orderings have received much attention from economists over the last decade examples in the macroeconomic literature include relationships between money and income sims 1972 feige and pearce money and interest rates pierce and wages and prices geweke 1975 in agricultural markets research in this area includes the sorting out of leads and lags between farm wholesale and retail prices heien miller acreage allotments and acreage supply response weaver and alternative price quotes for eggs bessler and schrader the methods used in these studies are empirical because they allow the data to specify the dynamic relationship between two variables economic theory is used only to suggest the variables to be related often theory is ambiguous on the explicit lead lag relationships between important variables and the variables themselves in such cases one can or must rely on strictly empirical methods burks discusses the complementary relationship between empirical and theoretical methods in scientific investigations agriculturalists interested in explaining producer behavior and forecasting livestock price and quantity movements have long grappled with problems of leads and lags attempts to explain short run movements in live cattle and hog inventories or slaughter levels using price variables have at times yielded unsatisfactory results for example shortrun quantity response to price change was found to be negative for cattle nelson and spreen myers havlicek henderson however a positive relation begins to appear with longer lengths of run the theory of optimal investment under risk explains this type of relationship that is treating cattle as both investment goods and as final products will generate the negative short run response of quantity to price such theory however will not be explicit about the particular lead lag relationships to be encountered most modern theories of decision making under risk suggest that such lags are dependent upon subjective probabilities of individual economic agents if one is unwilling to accept the existence of a rational probability following definetti then he will not be able to specify a priori the explicit leads and lags in a particular investment problem one must look at the data and infer such relationships this paper examines the lead lag relationships between livestock prices and various causal variables suggested by theory it explicitly tests the exogeneity of cattle on feed cattle slaughter and income on live cattle prices and the exogeneity of sow farrowings hog slaughter and income on live hog prices although explicit dynamic multivariate models are not formulated the paper s results do provide background evidence useful for their ultimate construction granger and newbold 1977 chap 7

information acquisition in interdependent value auctions we consider an auction environment with interdependent values each bidder can learn her payoff type through costly information acquisition we contrast the socially optimal decision to acquire information with the equilibrium solution in which each agent has to privately bear the cost of information acquisition in the context of the generalized vickrey clarke groves mechanism we establish that the equilibrium level exceeds the socially optimal level of information with positive interdependence the individual decisions to acquire information are strategic substitutes the difference between the equilibrium and the efficient level of information acquisition is increasing in the interdependence of the bidders valuations and decreasing in the number of informed bidders jel c72 c73 d43 d83

asymmetric price risk an econometric analysis of aggregate sow farrowings 1973 86 aggregate sow farrowing response to price risk is estimated where price risk is defined as the difference between expected price at decision time and realized price at acquisition or selling time asymmetric unfavorable deviations and symmetric favorable and unfavorable deviations forms of price risk are estimated utilizing cash and futures prices statistical results suggest that an asymmetric form of risk analysis is preferred to a symmetric form for both cash and futures markets

entry coordination and auction design with private costs of information acquisition i introduction in most auction literature bidders are passively endowed with private information about their valuations the analysis then focuses on optimal elicitation of private information on many occasions bidders may instead have to incur costs to collect this information 1 auction design in these cases has to balance between information acquisition and information elicitation which are interdependent the performance of an auction depends not only on the bidding equilibrium but also crucially on the information acquisition equilibrium 2 as a salient feature auction design with information acquisition costs has been complicated by entry coordination among bidders due to multiple entry equilibria issue in a symmetric independent private value ipv setting of mcafee and mcmillan 1987 with fixed information acquisition cost levin and smith 1994 note that the ex ante efficient and revenue maximizing auction a second price auction with no entry fee and no reserve induces many asymmetric entry equilibria other than the targeted symmetric one the existence of asymmetric entry equilibria in this setup fundamentally lies in bidders constant marginal cost of entry 3 information acquisition costs could be private information of bidders just as with their private information about values for example in the cases of construction procurements or u s timber auctions many aspects of prebid information acquisition and analyzation are private knowledge of bidders 4 clearly when information acquisition costs are private information of bidders auction design has to additionally take into account information elicitation at the information acquisition stage this aspect of analysis has yet to be reflected in the literature while the case with fixed information acquisition costs has been thoroughly studied by milgrom 1981 mcafee and mcmillan 1987 engelbrecht wiggans 1987 1993 harstad 1990 levin and smith 1994 mcafee quan and vincent 2002 ye 2004 2007 and cremer spiegel and zheng 2009 among others a widely recognized insight of these studies is that ex ante efficiency can be achieved through a second price auction while setting the reserve at the seller s valuation if ex ante entry fees can be used to extract all the expected surplus of bidders then there is a congruence between the revenue and total surplus 5 this article advances this line of research by studying the implications of private acquisition costs on auction design with an emphasis on bidders coordination at the information acquisition stage specifically we consider the ipv setting of mcafee and mcmillan 1987 and levin and smith 1994 while allowing the information acquisition costs to be bidders private information which follow a continuous distribution in light of our previous discussion this article attempts to answer the following questions 1 how are ex ante efficient and revenue maximizing auctions affected by this additional dimension of private information in other words how does information rent extraction at the entry stage affect the auction designs 2 can this private information alleviate rather than aggravate the problem of entry coordination with the dispersion in private information acquisition costs the multiplicity of entry equilibria arising from the constant marginal cost in levin and smith 1994 might be avoidable the types with higher information acquisition costs must have less incentive to enter which could reduce the number of entry equilibria the questions are will sufficient dispersion coordinate bidders and induce a unique entry if yes how much dispersion is enough due to the potential multiplicity of entry equilibria for any given mechanism it is rather difficult to compare performances across varieties of mechanisms to overcome this difficulty we come up with an alternative approach our analysis begins with characterizing efficient and revenue maximizing auctions for any given feasible entry pattern which can be described through a vector of bidders entry thresholds of acquisition costs

optimal auctions with asymmetric financial externalities abstract this paper studies optimal auction design with asymmetric linear financial externalities among bidders when the matrix that relates bidders payoffs to their payments is nonsingular the payment related component in the design objective must equal a unique linear combination of its counterparts in bidder s payoffs if all multipliers of the linear combination are nonnegative a modified myerson procedure is discovered for deriving the optimal design if any multiplier is negative an arbitrarily high value can be achieved for design objective by setting proper fixed transfers to bidders when the matrix is singular the unbounded optimum result typically prevails we applied our method to auctions with cross shareholdings and charity auctions for revenue maximizing and efficient designs

the maturing of socially responsible investment a review of the developing link with corporate social responsibility this paper reviews the development of socially responsible investment sri over recent years and highlights the prospects for an increasingly strong connection with the practice of corporate social responsibility the paper argues that not only has sri grown significantly it has also matured in particular it has become an investment philosophy adopted by a growing proportion of large investment institutions this shift in sri from margin to mainstream and the position in which institutional investors find themselves is leading to a new form of sri shareholder pressure although this bears some resemblance to lobbying campaigns which might take advantage of shareholder rights we seek to distinguish it as an important phenomenon in its own right one to which corporate executives are likely to be paying increasing attention in the years to come we further argue that this approach potentially meets some of the earlier ethical criticisms of certain forms of sri but ironically probably owes its existence to those pioneering approaches we conclude with some suggestions for further research to inform discussion of the issues highlighted in the paper

optimal search auctions abstract we study the design of profit maximizing single unit auctions under the assumption that the seller needs to incur costs to contact prospective bidders and inform them about the auction with independent bidders types and possibly interdependent valuations the seller s problem can be reduced to a search problem in which the surplus is measured in terms of virtual utilities minus search costs compared to the socially efficient mechanism the optimal mechanism features fewer participants longer search conditional on the same set of participants and inefficient sequence of entry

complements and substitutes in sequential auctions the case of water auctions we use data on sequential water auctions to estimate demand when units are com plements or substitutes a sequential english auction model determines the estimating structural equations when units are complements one bidder wins all units by paying a high price for the first unit thus deterring others from bidding on subsequent units when units are substitutes different bidders win the units with positive probability paying prices similar in magnitude even when the same bidder wins all units we re cover individual demand consistent with this stark pattern of outcomes and confirm it is not collusive but consistent with non cooperative behavior demand estimates are biased if one ignores these features

the evolution of environmentally responsible investment an adam smith perspective abstract this paper demonstrates that adam smith has common ground with contemporary social scientists who study the management of the common pool resources from an evolutionary perspective contrary to the caricature of smith presented by neoliberals as a promoter of self interest he recognized the value of other regarding behavior specifically focus is given to how such behavior can contribute to constructing institutional arrangements that can help to avoid damaging market excesses a study of the development of a process to encourage investment behavior that is environmentally responsible establishes that smith s work has relevance for addressing environmental issues in our contemporary complex market system

costly auction entry royalty payments and the optimality of asymmetric designs abstract we analyze optimal auction mechanisms when bidders base costly entry decisions on their valuations and bidders pay with a fixed royalty rate plus cash with sufficient valuation uncertainty relative to entry costs the optimal mechanism features asymmetry so that bidders enter with strictly positive but different ex ante probabilities when bidders are ex ante identical higher royalty rates which tie payments more closely to bidder valuations increase the optimal degree of asymmetry in auction design further raising revenues when bidders differ ex ante in entry costs the seller favors the low cost entrant whereas when bidders have different valuation distributions the seller favors the weaker bidder if entry costs are low but not if they are high higher royalty rates cause the seller to favor the weaker bidder by less and the strong bidder by more

participation costs and efficient auctions abstract suppose that risk neutral agents have independently and perhaps asymmetrically distributed private valuations for an indivisible object a mechanism assigns the object but it is costly to send messages to the coordinator in these circumstances the second price auction has an equilibrium that is classicallyex anteefficient given general opportunities to invest in information about or enhancements of own valuations in contrast the first price sealed bid auction may have no efficient equilibrium even if buyers are symmetric other properties of the first price auction are proved a semirevelation principle is established for mechanisms with participation costs journal of economic literatureclassification numbers d44 d82

buybacks with costly participation abstract posted price offers and first price auctions along with the multi unit discriminatory auction extension are two widely used mechanisms for allocating conservation contracts the choice between the two typically hinges on the trade off between the posted price s simplicity and the potential revenue gains of the auction in this paper we introduce a novel mechanism that attempts to bridge the gap between the performance of posted price offers and auctions a two price and lottery schedule combines the simplicity of the former with some of the flexibility of the latter using a model that incorporates agents cognitive and information costs of bidding we analyze how the ranking of allocative efficiency and cost effectiveness between the mechanisms varies as the wedge of participation costs increases when the number of bidders is endogenously determined by participation costs bid shading associated with a lack of competition in the auction compromises its cost effectiveness vis a vis the posted price and the lottery schedule we use data from three recent buybacks for fishing licenses conducted in maryland to calibrate our model and identify conditions under which the two price schedule outperforms the other mechanisms

auctions with heterogeneous entry costs it is well known that if bidders have independent private values and homogeneous entry costs a rst or second price auction with a reserve price equal to the seller s value maximizes social surplus and seller revenue and leaves bidders with no surplus further in mixed strategy entry equilibria social surplus and seller revenue decrease with the number of bidders we show that when entry costs are heterogeneous and private information the revenue maximizing reserve price is above the seller s value a positive inspection fee and a reserve price equal to the seller s value generates even more revenue and in either case bidders capture informational rents further seller revenue and social surplus may either increase or decrease with the number of bidders nevertheless seller revenue is asymptotically the same whether entry costs are homogeneous or heterogeneous our results are framed in terms of screening values rather than reserve prices and apply to any standard auction

resale in second price auctions with costly participation abstract we study sealed bid second price auctions with costly participation and resale each bidder chooses to participate in the auction if her valuation is higher than her optimally chosen participation cutoff if resale is not allowed and the bidder valuations are drawn from a strictly convex distribution function the symmetric equilibrium where all bidders use the same cutoff is less efficient than a class of two cutoff asymmetric equilibria existence of these equilibria without resale is sufficient for existence of similarly constructed two cutoff equilibria with resale moreover the equilibria with resale are more asymmetric and under a sufficient condition more efficient than the corresponding equilibria without resale

on discrimination in auctions with endogenous entry abstract when entry is exogenous strong buyers should be discriminated against weak buyers to maximize revenues myerson 1981 when entry is endogenous so that entrants expected payoffs do not depend on the proposed mechanism optimal discrimination takes a completely different form the revenue maximizing equilibrium requires that there should be no discrimination with respect to entrants irrespective of their ex ante characteristics besides those buyers who always participate should be discriminated against entrants independently of their strength these predictions are independent of the equilibrium selection when the number of potential entrants grows large the optimality of first price auctions is also discussed jel d44 h57

participation in auctions participation preparing offers in auction and procurement games e g bidding for spectrum rights or for control of corporations is very costly which calls for analyzing participation no less than how to play the games as part of equilibrium the result is a model with bi dimensional distribution of types as in jackson m o 1999 nonexistence of equilibria in auctions with both private and common values mimeo http www stanford edu jacksonm nonexist pdf and endogenous distribution of participants players with low production but high participation costs may decide not to participate forcing the auctioneer to pay higher than necessary prices to mitigate this phenomenon auctioneers may consider partially reimbursing participants for the costs they incur in preparing offers restricting attention to symmetric games we prove that the game we consider has a unique symmetric equilibrium with and without the reimbursement mechanism

ignorance promotes competition an auction model with endogenous private valuations we study a situation in which an auctioneer wishes to sell an object toone of n risk neutral bidders with heterogeneous preferences theauctioneer does not know bidders preferences but has private informationabout the characteristics of the ob ject and must decide how muchinformation to reveal prior to the auction we show that the auctioneerhas incentives to release less information than would be efficient andthat the amount of information released increases with the level ofcompetition as measured by the number of bidders furthermore in aperfectly competitive market the auctioneer would provide the efficientlevel of information

equilibria in second price auctions with participation costs abstract we investigate equilibria of sealed bid second price auctions with bidder participation costs in the independent private values environment we focus on equilibria in cutoff strategies participate and bid the valuation iff it is greater than the cutoff since if a bidder finds it optimal to participate she cannot do better than bidding her valuation when bidders are symmetric concavity strict convexity of the cumulative distribution function from which the valuations are drawn is a sufficient condition for uniqueness multiplicity within this class we also study a special case with asymmetric bidders and show that concavity convexity plays a similar role

socially responsible investment in the spanish financial market this paper reviews the development of socially responsible investment sri in the spanish financial market the year 1997 saw the appearance in spain of the first sri mutual fund but it was not until late 1999 that major spanish fund managers offered sri mutual funds on the retail market the development of sri in the spanish financial market has not experienced the high levels of development seen in other european countries such as france or italy where interest in sri began during the same period this paper presents an analysis of the impact of sri mutual funds managed by spanish fund managers comparing the evolution of managed assets and number of investors we also analyse the investment strategies adopted by these funds which mainly use negative screening criteria and the participation of non governmental organisations as institutional investors an analysis of the take up of socially responsible investment in the spanish financial market shows majors deficits in this process this is due to spanish investors having limited sensitivity to social issues and knowledge of sri and a lack of development of sri investment strategies such as engagement or shareholder activism by fund managers furthermore the take up of sri mutual funds in the spanish financial market coincided with a fall in the stock market at the beginning of the 21st century we conclude with an analysis of the relationship between sri and corporate social responsibility csr

corporate sustainability ratings an investigation into how corporations use the dow jones sustainability index abstract the purpose of this paper is to explore the use of the dow jones sustainability index djsi with an emphasis on canadian corporations the paper provides insight into the use of the djsi in several areas including the use of its logo the steps taken by corporations to achieve initial acceptance to the index and the steps corporations take to maintain their inclusion in the djsi a content analysis of publicly available information from 24 canadian corporations listed in the djsi north america djsina showed that less than half of those sampled used the djsi logo in their sustainability reports or on their websites the majority of the published references to the djsi were in highlighting corporate achievements or in providing background information on the index a survey of 10 experts from the canadian corporations listed in the djsina revealed a wide range of strategies for gaining and maintaining inclusion in the index particularly involving a large number of internal stakeholders in responding to data requests and working with third parties several suggestions for improving the djsi were also provided including streamlining the questionnaire improving coordination among sustainability ratings agencies and enhancing transparency
