agency conflict and corporate strategy the effect of divestment on corporate value among the various stakeholders of a firm senior managers are the most likely targets for private and public political pressures other stakeholder groups are less visible and may be perceived as less influential in corporate strategy formulation and implementation in some situations consequently senior executives may adopt corporate strategies in response to political pressures even if these strategies may be costly to shareholders in this study a special case is examined the effect of divestment of south african business units on firm value using data from 1984 through 1990 we examine the impact that announcements of divestments have upon the stock return behavior of publicly traded firms our results indicate that significant and negative excess returns accrue to shares of companies announcing divestments of south african operations these results are supportive of the premise that noneconomic pressures may influence managerial strategies rather than value enhancement goals 1997 by john wiley sons ltd

corporate environmental responsibility this paper offers directions for the continuing dialogue between business ethicists and environmental philosophers i argue that a theory of corporate social responsibility must be consistent with if not derived from a model of sustainable economics rather than the prevailing neoclassical model of market economics i use environmental examples to critique both classical and neoclassical models of corporate social responsibility and sketch the alternative model of sustainable development after describing some implications of this model at the level of individual firms and industries i offer an ethical justification of the sustainability alternative that is derived from the same values that underlie traditional market economics

an empirical examination of institutional investor preferences for corporate social performance this study investigates the pattern of institutional shareholding in the u k and its relationship with socially responsible behavior by companies within a sample of over 500 uk companies we estimate a set of ownership models that distinguish between long and short term investors and their largest components and which incorporate both aggregated and disaggregated measures of corporate social performance csp the results suggest that long term institutional investment is positively related to csp providing further support for earlier studies by johnson and greening 1999 academy of management journal 42 564 576 and graves and waddock 1994 academy of management journal 37 1034 1046 disaggregation of csp into its constituent components suggests that the pattern of institutional investment is also related to the form which csp takes investigation of the impact of investment screens on the selection of stocks suggests that long term institutional investors select primarily through exclusion rejecting those firms which have the worst csp

the statistical properties of daily foreign exchange rates 1974 1983 abstract this paper examines the statistical properties of daily rates of change of five foreign currencies from 1974 to 1983 the main purpose is to discriminate between two competing explanations for the observed heavy tails of the distribution that the data are independently drawn from a heavy tail distribution which remains fixed over time and that the data come from distributions which vary over time evidence point to the rejection of the first hypothesis further investigations show that the rejection can be attributed to changing means and variances in the data which can be described by a simple statistical model

conditional variance and the risk premium in the foreign exchange market abstract we investigate the existence of a risk premium in the foreign exchange market based on the conditional variance of market forecast errors the forecast errors are assumed to follow the arch process introduced by engle 1982 estimation and diagnostic testing of the model are discussed and results are presented for the currencies of the united kingdom france germany japan and switzerland

corporate social responsibility ownership structure and political interference evidence from china prior research suggests that ownership structure is associated to corporate social responsibility csr in developed countries this article examines whether and how ownership structure affects csr in emerging markets using chinese firms social responsibility ranking our empirical evidences show that for non state owned firms corporate ownership dispersion is positively associated to csr however for state owned firms whose controlling shareholder is the state this relation is reversed we attribute the reversed relationship to political interferences and further test this hypothesis by demonstrating that regional economic development is negatively related to csr for state owned firms due to decreased political interference in more developed areas this study is the first to directly examine the relationship between the dispersion of corporate ownership and csr in emerging markets and our results depict that it is important to consider ownership type in assessing csr in emerging market where state ownership is still prevalent such as china the results also reveal that firm size profitability employee power leverage and growth opportunity affect csr in china

does ownership always matter abstract the objective of this paper is to explain and illustrate the complex relationship between ownership arrangements and enterprise performance it is commonly argued that efficiency will be lower in the public sector than the private because enterprise objectives deviate from maximisation of profits and because monitoring arrangements are inadequate due to the absence of capital market discipline we argue that public ownership does make the owner manager relationship more complicated because the chain of principals and agents is expanded objectives are politically determined and these are conveyed by a policy making administrative structure to management but the relative efficiency of public as against private ownership actually depends on the efficacy of capital market monitoring on the political and constitutional system on the information and sanctions available to policy makers and on the nature of the management market variation in these factors can help to explain the different natures and roles of the public sector between countries

on non uniqueness in rational expectations models an attempt at perspective abstract many macroeconomic models involving rational expectations give rise to an infinity of solution paths even when the models are linear in all variables some writers have suggested that this non uniqueness constitutes a serious weakness for the rational expectations hypothesis one purpose of the present paper is to argue that the non uniqueness in question is not properly attributable to the rationality hypothesis but instead is a general feature of dynamic models involving expectations it is also argued that there typically exists in a very wide class of linear rational expectations models a single solution that excludes bubble or bootstrap effects one that occur only because they are arbitrarily expected to occur a systematic procedure for obtaining solutions free from such effects is introduced and discussed in addition this procedure is used to interpret and reconsider several prominent examples with solution multiplicities including ones developed by fischer black and john b taylor

a nonlinear stochastic rational expectations model of exchange rates abstract this paper constructs an example of a nonlinear stochastic rational expectations exchange rate with an explicit solution which is consistent with nonlinearities in short term movements in exchange rates the model consists of risk neutral agents who know the intervention rule of the central bank the resulting exchange rate switches between two linear stochastic processes one when intervention is present and another when intervention is absent nonlinearity enters through the probability of intervention which is time varying and depends on past outcomes this model is consistent with the empirical observations that the rate of change of the exchange rate has little autocorrelation but it exhibits strong nonlinear dependence and its variance changes over time jel j31 g15

a critique on the theory of financial intermediation abstract this comment discusses the review by franklin allen and anthony santomero of the theory of financial intermediation in the 20th anniversary special issue of the journal of banking and finance we do not fully agree with their view that risk management is only of recent importance to the financial industry and with putting central the concept of participation costs we suggest how the theory of financial intermediation might be developed further in order to understand present day phenomena in the financial services sector

financial intermediation and delegated monitoring this paper develops a theory of financial intermediation based on minimizing the cost of monitoring information which is useful for resolving incentive problems between borrowers and lenders it presents a characterization of the costs of providing incentives for delegated monitoring by a financial intermediary diversification within an intermediary serves to reduce these costs even in a risk neutral economy the paper presents some more general analysis of the effect of diversification on resolving incentive problems in the environment assumed in the model debt contracts with costly bankruptcy are shown to be optimal the analysis has implications for the portfolio structure and capital structure of intermediaries

state enterprise relation local economic priority and corporate environmental responsibility this paper empirically investigates how the state enterprise relation and local government s economic priority affect corporate environmental responsibility in a sample of chinese polluting enterpr

do lenders value corporate social responsibility evidence from china drawing on risk mitigation theory this article examines whether the improvement of firms social performance reduces debt financing costs cdfs in china the world s largest emerging market employing both the ordinary least square ols and the two stage instrumental variable regression methods we find that improved corporate social responsibility csr reduces the cdf when firms csr investment is lower than an optimal level however this relationship is reversed after the csr investment exceeds the optimal level firms with extremely low or extremely high csr are subject to a higher cdf the results also suggest that the optimal csr level for small firms is higher than that for large firms this study is the first to document a u shaped relationship between csr and cdf and also the first to investigate this relationship within an emerging market context

investor protection and corporate governance recent research has documented large differences among countries in ownership concentration in publicly traded firms in the breadth and depth of capital markets in dividend policies and in the access of firms to external finance a common element to the explanations of these differences is how well investors both shareholders and creditors are protected by law from expropriation by the managers and controlling shareholders of firms we describe the differences in laws and the effectiveness of their enforcement across countries discuss the possible origins of these differences summarize their consequences and assess potential strategies of corporate governance reform we argue that the legal approach is a more fruitful way to understand corporate governance and its reform than the conventional distinction between bank centered and market centered financial systems

the only game in town stock price consequences of local bias abstract theory suggests that in the presence of local bias the price of a stock should be decreasing in the ratio of the aggregate book value of firms in its region to the aggregate risk tolerance of investors in its region using data on u s states and census regions we find clear cut support for this proposition most of the variation in the ratio of interest comes from differences across regions in aggregate book value per capita regions with low population density e g the deep south are home to relatively few firms per capita which leads to higher stock prices via an only game in town effect

rational expectations econometric analysis of changes in regime an investigation of the term structure of interest rates abstract this paper is of interest both for its methodological contribution of new tools for analyzing rational expectations models and for its substantive conclusions concerning the term structure of interest rates during the monetary experiment of october 1979 the paper studies systems subject to changes in regime interpreted here as occasional discrete shifts in the parameters governing the time series behavior of exogenous economic variables the specification is shown to be quite tractable both theoretically and empirically the technique is used to analyze yields on three month treasury bills and ten year treasury bonds during 1962 to 1987 a constant parameter linear model for short term rates is shown to be inconsistent both with the univariate time series properties of short rates and with the observed bivariate relation between long and short rates under the expectations hypothesis of the term structure an alternative nonlinear model that admits the possibility of changes in regime affords a much better description of the univariate process for short rates moreover the cross equation restrictions implied by the expectations hypothesis of the term structure are consistent with the nonlinear specification indeed the residuals of the restricted relation have a standard error of only 0 8 basis points this is a third less than that of a completely unrestricted linear regression of long rates on short rates and compares with an unconditional standard deviation of long rates of 142 basis points i conclude that once the recognition by bond traders of changes in regime is taken into account the expectations hypothesis of the term structure of interest rates holds up fairly well for these data

the m form hierarchy and china s economic reform for 13 years from 1979 to 1991 economic reforms in china have generated a significant growth its gnp grew at an average annual rate of 8 7 or at 7 37 for per capita gnp 1 the chinese economic performance is in contrast to that of eastern europe and the former ussr the average growth rate of gdp in hungary was 1 8 between 1981 and 1985 and almost zero in 1988 and 1989 in poland the average gdp growth rate was less than 2 between 1981 and 1989 from both theoretical and policy perspectives china s outstanding reform performances and associated differ ent reform strategies from those of eastern europe and the ussr are particularly interesting and puzzling there are two popular views in explaining the differences between china and eastern europe the first view states that china was at a much lower development stage than eastern europe and the ussr 3 the second view argues that china has followed a gradual and piecemeal approach as

short run fluctuations in foreign exchange rates evidence from the data 1973 1979 abstract the paper examines the statistical properties of daily changes in foreign exchange fx rates for nine currencies it finds that these changes are leptokurtotic i e have long tailed and sharp peaked histograms the evidence suggests that this leptokurtosis does not arise from an underlying paretian stable distribution nor from a stationary mixture of normal distributions but rather from normal processes with time varying parameters this finding casts doubt on the validity of many standard techniques t stats arima methods some moving statistics for estimating the time varying parameters are also presented

modeling heteroscedasticity in daily foreign exchange rates this article estimates autoregressive conditionally heteroscedastic arch and generalized arch garch models for five foreign currencies using 10 years of daily data a variety of arch and garch specifications a number of nonnormal error densities and a comprehensive set of diagnostic checks it finds that arch and garch models can usually remove all heteroscedasticity in price changes in all five currencies goodness of fit diagnostics indicate that exponential garch with certain nonnormal distributions fits the canadian dollar extremely well and the swiss franc and the deutsche mark reasonably well only one nonnormal distribution fits the japanese yen reasonably well none fit the british pound

morals or economics institutional investor preferences for corporate social responsibility this article presents the results of a study that analysed whether social responsibility had any bearing on the decision making of institutional investors being that institutional investors prefer socially aligned organizations this study explored to what extent the corporate actions and or social environmental investments influenced their decisions our results suggest that there are specific variables that affect the perceived value of the organization leading to decisions to not only invest but whether to hold or sell the shares and therefore having a consequential impact on the capital market s valuation

event studies in management research theoretical and empirical issues we examined the use of event studies in management research and found that there was inadequate attention paid to theoretical and research design issues this lack of attention may lead to false in

institutional interest ownership type and environmental capital expenditures evidence from the most polluting chinese listed firms this study empirically examines whether firms environmental capital expenditures impact institutional investors investment decisions in the chinese market we particularly examine the impact of ownership type on the relationship of environmental capital expenditures and the behavior of different types of institutional investors by classifying institutional investors into two categories short term and long term investors in addition this study further investigates whether environmental capital expenditures related to ownership type increase firm value we find that long term institutional investors tend to invest in state owned firms soes making environmental capital expenditures results also indicate that with governmental backing and encouragement the market value of soes making more environmental capital expenditures is likely to increase however no similar results are found for non soes

collapsing exchange rate regimes some linear examples abstract we construct a pair of linear examples to study the collapse time of a fixed exchange rate regime the first example is a perfect foresight continuous time model which allows calculation of the exact collapse time and the tracking of reserves the second example is a discrete time stochastic model which yields an endogenous probability distribution over the collapse time and produces a forward discount of the exchange rate

the impact of environmental regulation shadow economy and corruption on environmental quality theory and empirical evidence from china abstract mounting environmental pressures led china to focus on the effectiveness of the environmental regulation to control pollution since the shadow economy or underground economic activities that are not included in official statistics accounts for an increasing fraction of china s economy its impacts on environmental quality should be carefully evaluated in this study the main research questions are as follows 1 what is the extent of the effect of environmental regulation on environmental quality and 2 what are the factors that influence the impact of environmental regulation on environmental pollution a theoretical model is developed to explain the relationship among the environmental regulation shadow economy and environmental quality in china an empirical analysis is conducted to test the three propositions of the model thereby examining the explanatory power of the theoretical model concretely using panel data from 30 provinces for the period of 1998 2012 the generalized method of moments gmm method is employed to control for potential endogeneity and introduce dynamic effects the estimation results indicate that stringent environmental regulation and the level of the shadow economy are both positively related to china s environmental pollution however the results also indicate that tighter environmental control would help reduce pollution at a given level of the shadow economy moreover an increase in the proportion of corrupt officials may weaken the environmental regulation which would consequently lead to the increase in illegal production and total pollutant emissions besides many economic and social factors may also affect the environmental quality for instance the development of secondary industry contributes toward an increase in pollutant emissions however increased research and development r d spending on eco friendly industrial operations can help to reduce pollution

to steal or not to steal firm attributes legal environment and valuation data on corporate governance and disclosure practices reveal wide within country variation that decreases with the strength of investors legal protection a simple model identifies three firm attributes related to that variation investment opportunities external financing and ownership structure using firm level governance and transparency data from 27 countries we find that all three firm attributes are related to the quality of governance and disclosure practices and firms with higher governance and transparency rankings are valued higher in stock markets all relations are stronger in less investor friendly countries demonstrating that firms adapt to poor legal environments to establish efficient governance practices

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