sustainable de growth mapping the context criticisms and future prospects of an emergent paradigm article i nfo sustainable de growth is both a concept and a social grassroots northern movement with its origins in the fieldsofecologicaleconomics socialecology economicanthropologyand environmentalandsocialactivistgroups this paper introduces the concept of sustainable de growth by mapping some of the main intellectual influences fromthese fields with special focus on the francophone and anglophone thinking about this emergent notion we propose hypotheses pertaining to the appeal of sustainable de growth and compare it to the messages enclosed within the dominant sustainable development idea we scrutinize the theses contradictions and consequences of sustainable de growth thinking as it is currently being shaped by a heterogeneous body of literature and as it interacts with an ample and growing corpus of social movements we also discuss possible future paths for the de growth movement compared to the apparent weakening of the sustainable development paradigm

international trade of scarce water abstract recent analyses of the evolution and structure of trade in virtual water revealed that the number of trade connections and volume of virtual water trade have more than doubled over the past two decades and that developed countries increasingly import water embodied in goods from the rest of the world to alleviate pressure on domestic water resources at the same time as demand continues to increase and climate change threatens to alter hydrological cycles water scarcity is a growing problem does research into virtual water trade need to consider water scarcity and differentiate flows out of water scarce regions from flows out of water abundant regions previous studies sum and compare virtual water volumes originating in countries experiencing vastly different degrees of water scarcity we therefore incorporate water scarcity into an assessment of global virtual water flows we use input output analysis to include indirect virtual water flows we find that the structure of global virtual water networks changes significantly after adjusting for water scarcity

taxes and capital structure understanding firms savings abstract the u s non financial corporate sector became a net lender to the rest of the economy in the early 2000s with close to half of all publicly traded firms holding financial assets in excess of their debt liabilities we develop a simple dynamic model of debt and equity financing where firms strive to accumulate financial assets even though debt is fiscally advantageous relative to equity moreover firms find it optimal to fund additional financial asset holdings through equity revenues the calibrated model matches well the distribution of public firms balance sheets during the 2000s and correctly predicts which firms are net savers

the physical dimension of international trade part 1 direct global flows between 1962 and 2005 abstract the physical dimension of international trade is attaining increased importance this article describes a method to calculate complete physical trade flows for all countries which report their trade to the un the method is based on the un comtrade database and it was used to calculate world wide physical trade flows for all reporting countries in nine selected years between 1962 and 2005 the results show increasing global trade with global direct material trade flows reaching about 10 billion tonnes in 2005 corresponding to a physical trade volume of about 20 billion tonnes adding both total imports and total exports the share from european countries is declining mainly in favour of asian countries the dominant traded commodity in physical units was fossil fuels mainly oil physical trade balances were used to identify the dominant resource suppliers and demanders australia was the principal resource supplier over the period with a diverse material export structure it was followed by mainly oil exporting countries with varying volumes as regards to regions latin america south east asian islands and central asia were big resource exporters mostly with increasing absolute amounts of net exports the largest net importers were japan the united states and single european countries emerging countries like the asian tigers with major industrial productive sectors are growing net importers some of them to an even higher degree than european countries altogether with the major exception of australia and canada industrialized countries are net importers and developing countries and transition countries are net exporters but there are important differences within these groups

a theory of corporate financial decisions with liquidity and solvency concerns this paper studies the impact of both liquidity and solvency concerns on corporate finance i present a tractable model of a firm that optimally chooses capital structure cash holdings dividends and default while facing cash flows with long term uncertainty and short term liquidity shocks the model explains how changes in solvency affect liquidity and also how liquidity concerns affect solvency via capital structure choice these interactions result in a dynamic cash policy in which cash reserves increase in profitability and are positively correlated with cash flows the optimal dividend distributions implied by the model are smoothed relative to cash flows i also find that liquidity concerns lead to a decrease of dispersion of credit spreads

costly arbitrage evidence from closed end funds arbitrage costs lead to large deviations of prices from fundamentals using a sample of closed end funds i find that the market value of a fund is more likely to deviate from the value of its assets 1 for funds with portfolios that are difficult to replicate 2 for funds that pay out smaller dividends 3 for funds with lower market values and 4 when interest rates are high these factors are related to the magnitude of the deviation as opposed to the direction i e whether discount or premium and explain a quarter of cross sectional mispricing variation these findings are consistent with noise trader models of asset pricing

strategic price complexity in retail financial markets abstract there is mounting empirical evidence to suggest that the law of one price is violated in retail financial markets there is significant price dispersion even when products are homogeneous also despite the large number of firms in the market prices remain above marginal cost and may even rise as more firms enter in a non cooperative oligopoly pricing model i show that these anomalies arise when firms add complexity to their price structures complexity increases the market power of the firms because it prevents some consumers from becoming knowledgeable about prices in the market in the model as competition increases firms tend to add more complexity to their prices as a best response rather than make their disclosures more transparent because this may substantially decrease consumer surplus in these markets such practices have important welfare implications

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

competition risk and managerial incentives this paper examines how the degree of competition among firms in an industry affects the optimal incentives that firms provide to their managers a central assumption is that there is free entry and exit in the industry which implies that changes in the nature of competition lead to changes in the equilibrium market structure the main result is that as the intensity of product market competition increases as a result of greater product substitutability or greater market size principals unambiguously provide stronger incentives to their agents to reduce costs at the same time more intense competition also leads to more volatile firm level profits consequently managers incentives are positively correlated with firm level risk consistent with empirical evidence a decrease in the cost of entering the market has the opposite effect on incentives but still induces a positive correlation between risk and incentives

temporary versus permanent shocks explaining corporate financial policies we investigate corporate financial policies in the presence of both temporary and permanent shocks to firms cash flows in our framework cash flows can be negative and are imperfectly correlated with firm value and earnings volatility differs from asset volatility these results are consistent with empirical stylized facts they are also contrary to the implications of existing dynamic capital structure models that allow only for permanent shocks to cash flows temporary shocks increase the importance of financial flexibility and may provide an intuitively simple and realistic explanation of empirically observed financial conservatism and low leverage phenomena the theoretical framework developed in this article general enough to be used in various corporate finance applications jel g12 g32 g33

tracing the impacts of a northern open economy on the global environment the globalization of the world economy has increased resource flows around the planet raising pressures on the environment historically northern industrialized economies have been responsible for the majority of resource consumption while developing countries have suffered the associated social and environmental impacts this article analyzes the extra territorial responsibility of the basque economy europe to illustrate the responsibility of northern open economies towards the global environment to do this we i analyze the material and energy flows of the basque economy their source and impacts on other regions of the world ii study the impact of the economic and investment activities of basque companies abroad and iii examine together with other paradigmatic examples three case studies from latin america east africa and southeast asia that represent the liabilities of northern economies in the global south this approach allows us to connect production and consumption processes in affluent countries with associated socio ecological impacts in the extraction frontiers in order to better understand and potentially transform current economic patterns and their consequences in addition the study indicates how to bridge the gap between local and global scales creating a useful approach to raising social awareness and informing public policies in resource intensive societies

material use and material efficiency in latin america and the caribbean different world regions have followed very different trajectories for natural resources use over the recent decades latin america has pursued a development path based largely on exports of primary resources adopting this path has characteristic environmental and social impacts in this paper we provide the first broad based estimate of material use and material efficiency for the region beginning in 1970 and extending to the onset of the global financial crisis in 2008 the results show a region with rapidly growing primary materials consumption which is simultaneously becoming less efficient at converting those resources into national income using an ipat framework we found that population growth and rising per capita incomes made comparable contributions to growing material use while technological change as reflected in material intensity did not moderate consumption increasing materials intensity observed for the region as a whole is also observed for most individual countries this contrasts with some other world regions and implies that many countries in latin america and the caribbean will confront higher environmental pressures than expected when expanding their extractive industries to take advantage of new demand from other world regions while simultaneously supplying the requirements for their own domestic industrial transformations and urbanization

equilibrium prices in a vertically coordinated fishery abstract competition among processing firms is analyzed in a fishery that is managed under a total allowable catch constraint firms compete first in the ex vessel market for round fish and then in the downstream consumer market nash equilibrium prices are characterized at each stage of the vertical market when the number of processors is sufficiently large equilibrium prices are approximately walrasian the ex vessel price is close to the processor marginal valuation of the round fish and the consumer price clears the total quantity of processed fish implications for market structure conduct and performance and fisheries management policy are drawn

product market competition and analyst forecasting activity international evidence abstract in this study we investigate how product market competition affects the extent of analyst following and the properties of analyst forecasts using a broad sample of firms from 37 countries over the 1990 2008 period we find that firms that operate in more concentrated industries and with stronger pricing power are associated with greater analyst following higher forecast accuracy and lower forecast dispersion moreover the effect of product market power on analyst following and forecast properties is more pronounced in countries with less effective competition laws and higher entry costs these findings suggest that high industry concentration and a dominant market position enhance the earnings predictability of firms and lower their information uncertainty and that country level institutions that promote competition effectively constrain the power in product markets

the effect of value line investment survey rank changes on common stock prices abstract the information content of value line investment survey rank changes is investigated the results suggest rank changes affect common stock prices but the effect varies by the type of rank change changes from rank 2 to rank 1 have the most dramatic impact on prices a cross sectional analysis finds small firms have a greater reaction to a rank change than larger firms which supports theories on the frequency of report arrival and precision of information a speed of adjustment test concludes the prices of individual securities adjust to the information in a rank change over a multiple day period

the effect of transaction size on off the run treasury prices this paper examines intra day trading data from the inter dealer broker market for u s treasury securities and measures the degree of price pressure in the off the run treasury market as is well known securities that would appear to be very close substitutes i e on the run and off the run treasury bonds behave as if there is some degree of market segmentation this is the first systematic study of the off the run treasury note and bond market focused entirely on a price pressure effect using intra day data the paper analyzes price pressure through matched pairs of securities that differ only in liquidity

an empirical equilibrium model of a decentralized asset market i estimate a search and bargaining model of a decentralized market to quantify the effects of trading frictions on asset allocations and asset prices and to quantify the effects of intermediaries that facilitate trade using business aircraft data i find that relative to the walrasian benchmark 12 4 percent of the assets are misallocated and prices are approximately 27 3 percent lower dealers play an important role in reducing frictions in a market with no dealers 15 7 percent of the assets would be misallocated perhaps surprisingly in a market with no dealers prices would increase by 2 8 percent because sellers outside options improve relative to buyers thus counteracting the effects of higher search costs and slower trade on asset prices

evidence that the zero earnings discontinuity has disappeared abstract discontinuities in earnings distributions at zero have been widely cited as evidence of earnings management but not without controversy recent research suggests discontinuities may be mere artifacts of certain research design choices we find that the well known zero earnings discontinuity disappears soon after passage of the sarbanes oxley act sox and has not returned we also find that neither the discontinuity nor its disappearance require the effects of widely cited alternative non earnings management explanations for the zero earnings discontinuity

international comparison of resource use and its relation to economic growth the development of total material requirement direct material inputs and hidden flows and the structure of tmr abstract resource flows constitute the materials basis of the economy at the same time they carry and induce an environmental burden associated with resource extraction and the subsequent material flows and stocks which finally end up as waste and emissions a reduction of this material throughput and the related impacts would require a reduction of resource inputs and breaking the link between resource consumption and economic growth would require an increase in resource productivity material flow analysis mfa can be used to quantify resource flows and indicate resource productivity in this article we study the available empirical evidence on the actual de linkage of material resource use and economic growth we compare resource use with respect to total material requirement tmr and direct material input dmi for 11 and 26 countries respectively and the european union eu 15 the dynamics of tmr as well as of the main components are analysed in relation to economic growth in order to show whether there is a decoupling relative or absolute from gdp and a change of the metabolic structure in the course of economic development dmi cap so far only decoupled from gdp cap in relative terms that is in most countries it reached a rather constant level but with the exception of czech republic showed no absolute decline yet tmr cap was reduced in two high income countries and one low income country due to political influence changes in tmr were more influenced by hidden flows hf than by dmi we analyse the dynamics of the structure and composition of tmr in the course of economic development in general the economic development of industrial countries was accompanied by a shift from domestic to foreign resource extraction different relations can be discovered for the share of biomass fossil fuel resources construction resources and metals and industrial minerals

mining and poverty reduction transforming rhetoric into reality abstract this article critically evaluates the contribution that mining has made to poverty reduction and assesses the prospects for better performance in the future the article starts from the two assumptions that mineral resources are a potentially great source of wealth for poor countries and that the various ill effects associated with the resource curse are not inevitable it then directs its attention toward the world bank a leading advocate of mining led development and an institution with a core mandate to reduce poverty employing the world bank s own conceptualization of poverty as an analytical framework the article demonstrates that mining has a dismal empirical track record to date in poverty reduction while the theoretical reasons to believe that mining can contribute to poverty alleviation are perhaps sound the reality of mineral led development has not lived up to its rhetorical promise the article elucidates problems with existing approaches and evaluates the world bank s recently concluded extractive industries review as a dramatic new paradigm shift in thinking on mining and poverty reduction it concludes that mining can positively contribute toward poverty alleviation but only if a variety of demanding preconditions are met

endogeneity and the dynamics of internal corporate governance abstract we use a well developed dynamic panel generalized method of moments gmm estimator to alleviate endogeneity concerns in two aspects of corporate governance research the effect of board structure on firm performance and the determinants of board structure the estimator incorporates the dynamic nature of internal governance choices to provide valid and powerful instruments that address unobserved heterogeneity and simultaneity we re examine the relation between board structure and performance using the gmm estimator in a panel of 6 000 firms over a period from 1991 to 2003 and find no causal relation between board structure and current firm performance we illustrate why other commonly used estimators that ignore the dynamic relationship between current governance and past firm performance may be biased we discuss where it may be appropriate to consider the dynamic panel gmm estimator in corporate governance research as well as caveats to its use

estimating time varying bargaining power a fishery application i introduction many economists and ecologists alike have supported rights based management systems as a form of fishery management that addresses the causes of inefficient resource use e g costello et al 2008 despite these convincing studies most fisheries have yet to impose any form of rights based management in fact in the united states from 1996 through 2002 a moratorium was in effect on the creation of management systems that assigned fishing quota to individual vessels often referred to as individual fishing quota ifq management 1 there has been some political resistance to the move from regulated open access management which imposes total catch limits for the fishery but no individual limits to rights based management which generally imposes some form of individual fishing rights at the core of this resistance is not the question of efficiency but the possibility of potentially severe changes or distortions in rent distribution in the market between fishers and processors the ex vessel market processors and some researchers have been concerned that fishers will achieve near total rent extraction when ifqs are given only to fishers as is typically the case e g matulich et al 1996 models that assume complete rent extraction by fishers also assume that the ex vessel market is perfectly competitive for many fisheries this assumption of perfect competition is not appropriate the geographic remoteness of many fishing areas often creates markets in which multiple fishing vessels must deliver their catch to a small number of processing facilities when one considers this remoteness together with the possibility of limited entry restrictions on the harvesting and processing sectors processing firm consolidation fishers bargaining associations and instances of fisher processor vertical integration it is evident that there are a host of reasons why ex vessel markets are normally not completely competitive thus the creation of property rights through ifqs occurs not in an idealized purely competitive environment but in an imperfectly competitive market with a myriad of factors that affect both processors and fishers abilities to extract rents a bilateral bargaining framework has been suggested by several researchers as an alternative to the competitive market specification for some ex vessel markets e g halvorsen et al 2000 matulich et al 1995 munro 1982 in this framework fishers act as upstream monopolist oligopolists selling whole fish to downstream monopsonistic oligopsonistic fish processors we follow this specification to analyze the rent distribution effect that switching to ifq management has had on a specific fishery the alaskan sablefish fishery in doing so we develop an unobserved components ucs inspired econometric technique to estimate a fixed quantity i e the quantity transacted is exogenously determined bilateral bargaining model in the presence of unobserved reservation prices and potentially time varying bargaining power this technique is general in its formulation and could thus have applicability in other contexts given the wide range of industries for which the bilateral bargaining framework is appropriate the organization of the paper is as follows in the next section we explain how imposing property rights in a fishery through an ifq system may affect the bargaining position of fishers and processors in the ex vessel market in section iii we introduce the general purpose model of bilateral bargaining used in this study and the econometric technique we use to estimate this model we provide some brief background information for the alaskan sablefish fishery in section iv in section v we present and discuss our estimation results and we conclude in the final section ii impacts of ifq management matulich et al 1996 present a theoretical model which is restated in matulich and sever 1999 with both competitive fishing and processing sectors to analyze the effect of ifq management implementation on rent distribution between the two sectors

why company specific risk changes over time company specific risk climbed steadily between 1962 and 1999 in the u s market but fell sharply between 2000 and 2003 this article explores the hypothesis that three factors are primarily responsible for observed changes in company specific risk changes in the market weights of riskier industries changes in the relative role of small capitalization stocks in the market and measurement error associated with changes in within industry concentration empirical tests reveal that each factor contributes to changes in company specific risk over time and that combined these three factors largely explain changes in company specific risk over the past 40 years

a glocal environmental movement against gold mining pascua lama in chile abstract gold mining projects are spreading in latin america due to increasing international interest in gold and to the legal reforms that attract mining investment to the region as metal mining has critical social and environmental impacts conflicts related to it are also soaring the conflict around the pascua lama mining project in chile is a paradigmatic example of these conflicts starting with the defence of some mountain glaciers being endangered by the mine local protests have been internationalized it has become one of the most important chilean environmental conflicts of recent years in order to characterise the movement the article analyses its social bases or participants the values and arguments articulated and the strategies developed this agency analysis shows that it is not a case of environmentalism of the poor or of post materialist environmentalism but a glocal environmental movement the movement has not achieved to stop the project due to structural limitations but it has been able to problematise and politicise the concept of development in the affected chilean valley

linking political ecology with ecological economics in tree plantation conflicts in cameroon and ecuador abstract industrial tree plantations are rapidly expanding worldwide and notably causing a growing number of conflicts between companies and local populations such conflicts the focus of the article have been neglected by ecological economists although there is a proliferation of related reports by environmental non governmental organizations this paper uses empirical evidence to show how elements of political ecology and ecological economics can be combined for understanding the languages of valuation deployed in tree plantation conflicts in southern countries combining qualitative fieldwork on a cameroonian rubber plantation and an ecuadorian eucalypt plantation with a methodological framework taken from the study of social metabolism we find that both conflicts although with different emphasis arise because of land and biomass appropriation ground clearing pollution from agrochemicals and water shortage and are expressed as conflicts on valuation the metabolism of such tree plantations through the exchanges of materials with the local environment explains the bio physical basis of such conflicts in the cameroon case resistance is mainly sporadic and individual while in ecuador a grassroots organization has been able to respond to rural demands in a structured way both patterns of resistance are found in other present day resource extraction conflicts

toward a more complete model of individual transferable fishing quotas implications of incorporating the processing sector abstract economic analyses of individual transferable quota itq fisheries management traditionally have focused on the harvesting sector however harvester decisions impact the economic performance of co dependent processing firms this paper incorporates both sectors in an analysis of the effect of itqs on commercial fisheries results show that as a consequence of season elongation under a harvester only allocation of fishing rights capital nonmalleability implies that processor quasi rents will be redistributed to harvesters these losses could promote political gridlock and jeopardize adoption of an itq policy unless they are fully compensated or unless redistribution is avoided by a policy superior initial allocation of rights to both harvesters and processors

can equity volatility explain the global loan pricing puzzle we examine whether equity volatility can explain the difference in syndicated corporate loan spreads paid by u s and european borrowers first documented by carey and nini 2007 we argue that ols estimates of the association between equity volatility and loan spreads are biased and inconsistent we suggest instrumental variables that potentially identify consistent estimates our instrumental variable results indicate that there is no statistically significant difference in loan spreads paid by u s and european borrowers and that ols estimates of the association between idiosyncratic equity volatility and corporate loan spreads are biased downward by about a factor of 5

growth in global materials use gdp and population during the 20th century the growing industrial metabolism is a major driver of global environmental change we present an assessment of the global use of materials since the beginning of the 20th century based on the conceptual and methodological principles of material flow accounting mfa on the grounds of published statistical data data compilations and estimation procedures for material flows not covered by international statistical sources we compiled a quantitative estimate of annual global extraction of biomass fossil energy carriers metal ores industrial minerals and construction minerals for the period 1900 to 2005 this period covers important phases of global industrialisation and economic growth the paper analyses the observed changes in the overall size and composition of global material flows in relation to the global economy population growth and primary energy consumption we show that during the last century global materials use increased 8 fold humanity currently uses almost 60 billion tons gt of materials per year in particular the period after wwii was characterized by rapid physical growth driven by both population and economic growth within this period there was a shift from the dominance of renewable biomass towards mineral materials materials use increased at a slower pace than the global economy but faster than world population as a consequence material intensity i e the amount of materials required per unit of gdp declined while materials use per capita doubled from 4 6 to 10 3 t cap yr the main material groups show different trajectories while biomass use hardly keeps up with population growth the mineral fractions grow at a rapid pace we show that increases in material productivity are mostly due to the slow growth of biomass use while they are much less pronounced for the mineral fractions so far there is no evidence that growth of global materials use is slowing down or might eventually decline and our results indicate that an increase in material productivity is a general feature of economic development

trade and the environment from a southern perspective the relationship between free trade and the environment is one of the main issues of contention between environmental and ecological economics environmental economics assumes a positive relationship between free trade economic growth and environmental policies environmental externalities may cause important damage however trade is not to be blamed for this instead the fault lies with policy inadequacies at the national level on the other hand some ecological economists criticise the assumptions of environmental economics especially the immobility of production factors and the positive correlation between income and environmental quality they plead for measures to prevent deterioration of northern environmental standards in a race to the bottom due to ecological dumping from the south in this paper we argue that neither environmental economics nor northern ecological economics take into account the structural conditions determining the international trade system based on some new empirical evidence on material flows we stress the notion of environmental cost shifting if physical and political ecology perspectives are adopted a southern approach to the trade and environment issue may arise 2001 elsevier science b v all rights reserved

the idiosyncratic volatility puzzle time trend or speculative episodes campbell lettau malkiel and xu 2001 document a positive trend in idiosyncratic volatility during the 1962 1997 period we show that by 2003 volatility falls back to pre 1990s levels furthermore we show that the increase and subsequent reversal is concentrated among firms with low stock prices and high retail ownership this evidence suggests that the increase in idiosyncratic volatility through the 1990s was not a time trend but rather an episodic phenomenon at least partially associated with retail investors results from cross sectional regressions conditional trend estimation stock split events and attention grabbing events are consistent with a retail trading effect the author 2009 published by oxford university press on behalf of the society for financial studies all rights reserved for permissions please email journals permissions oxfordjournals org oxford university press

does ecologically unequal exchange occur the hypothesis of ecologically unequal exchange posits that low and middle income developing nations maintain an ecological deficit with wealthy developed nations exporting natural resources and high impact commodities thereby allowing wealthy economies to avoid operating ecologically impactful industries at home in this survey we assess the footprint of consumption of 187 countries using eight indicators of environmental pressure in order to determine whether or not this phenomenon occurs we use input output analysis with a new high resolution global multi region input output table to calculate each trading pair s balance of trade in biophysical terms of ghg emissions embodied water and scarcity weighted water content air pollution threatened species human appropriated net primary productivity total material flow and ecological footprint we test three hypotheses that should be true if ecologically unequal exchange occurs one the inter regional balance of trade in biophysical terms is disproportional to the balance of trade in financial terms we find this is true though not strongly so two exports from developing nations are more ecologically intensive than those from developed nations we find this is true three high income nations disproportionately exert ecological impacts in lower income nations we find this is false high income nations are mostly exporters not importers of biophysical resources

product market pricing power industry concentration and analysts earnings forecasts this is the first study to establish a link between product market power and analysts earnings forecast accuracy and bias relating two different dimensions of market power to earnings forecastability we document that a a firm s relative pricing power and b its industry concentration are strong positive determinants of analysts earnings forecast accuracy we find that forecasting earnings of higher market power firms is less complex due to their ability to withstand cost shocks as well as greater informational efficiency enjoyed by such firms further forecast optimism increases with weakening product market pricing power and with lower industry concentration the knowledge derived from this study will hopefully improve the accuracy of equity valuation and thereby engender better buy side stock selections and sell side recommendations by analysts our analysis also suggests that brokerage firms compensating analysts based on forecast accuracy need to adjust for the differential in the information complexity of different industries

patterns of change in material use and material efficiency in the successor states of the former soviet union the successor states of the former soviet union present a unique opportunity to study the changes in the socio metabolic profile of a cohort of nations which underwent a radical and contemporaneous shift in economic system that change was from being regions within an economically integrated centrally planned whole to being independent nations left to find their own place in the global economic system the situation of these nations since the dissolution of the soviet union provides a rare experiment in which we might observe the influence of the different starting conditions of each nation on the development path it subsequently followed and the attendant socio metabolic profiles which resulted here we take the opportunity to examine patterns for the region as a whole and for three individual countries we also examine the relative importance of three different drivers of material consumption using a version of the ipat framework finally an area for follow on investigation was suggested by a significant positive correlation observed between the economic growth of individual successor states and the degree to which they improved their material productivity this latter is of potential importance in assessing whether dematerialization acts primarily to accelerate or retard economic growth

qualitative similarity and stock price comovement abstract i introduce a method for gauging the qualitative similarity of firm specific information based on linguistic commonality in newswire text i show that this new qualitative similarity measure predicts future cross firm return correlation even after accounting for the pair s contemporaneous price comovement common exposures to systematic risk firm liquidity price index membership text volume headquarters location product similarity shared mutual fund or institutional ownership common analyst following and newswire co mentions i also demonstrate that content produced solely by journalists cannot predict an economically meaningful portion of future comovement out of sample tests confirm that knowledge of qualitative similarity can also reduce portfolio risk

idiosyncratic return volatility cash flows and product market competition over the past 40 years the volatility of the average stock return has drastically outpaced total market volatility thus idiosyncratic return volatility has dramatically increased we estimate this increase to be 6 per year consistent with an efficient market this result is mirrored by an increase in the idiosyncratic volatility of fundamental cash flows we argue that these findings are attributable to the more intense economy wide competition various cross sectional and time series tests support this idea economic competitiveness facilitates reinterpretation of the results from the cross country r2 literature as well as the us idiosyncratic risk literature jel g12 g14

exvessel price determination in the alaska king crab fishery a formula price contract under uncertainty abstract commercial fisheries industry structure often suggests exvessel price formation occurs in the context of a competitive harvesting sector and an oligopsonistic processing sector however industry conduct leading to a determination of exvessel price can be notably at odds with this inference this paper presents empirical evidence that the conduct of at least one such fishery the alaska king crab industry may emulate bilateral monopoly exvessel price determination is consistent with an implicit formula price contract in which fishers behave as monopolists through bargaining associations while processors behave as countervailing monopsonists even in the absence of explicit collusion both sectors appear to behave in a manner consistent with joint expected profit maximization with profit shares apportioned via the implicit formula price contract this price formation process simplifies empirical analysis of the bilateral monopoly conduct by avoiding complicated game theoretic bargaining models

market microstructure and securities values evidence from the tel aviv stock exchange abstract this paper examines the value effects of improvements in the trading mechanism selected stocks on the tel aviv stock exchange were transferred gradually from a daily call auction to a mechanism where the call auction was followed by iterated continuous trading sessions this event was associated with a positive and permanent price appreciation the cumulative average market adjusted return over a period that started five days prior to the announcement and ended 30 days after the stocks started trading by the new method was approximately 5 5 in addition we find positive liquidity externalities spillovers across related stocks and improvements in the value discovery process due to the improved trading method finally there was a positive association between liquidity gains and price appreciation

towards an ecological theory of unequal exchange articulating world system theory and ecological economics abstract the focus of this paper is on how an ecological perspective might provide us with an analytically more precise way of defining unequal exchange it is only by looking at the ecological conditions of human economies that we can adequately conceptualize the mechanisms which generate inequalities in distribution considerations of market power aside neoclassical economic ideology has dispelled all possible criteria for assessing a market transaction as unequal or unfair one way to assess the occurrence of unequal exchange may be to look at the direction of net flows of energy and materials concrete productive potential but without falling into the trap of equating productive potential with economic value on the contrary it can be analytically demonstrated that unequal exchange emerges from a kind of inverse relationship between productive potential and economic value the notion of a reasonable market price conceals the fact that what is being exchanged are intact resources for products representing resources already spent if we consider longitudinally along the production process any given set of fuels and raw materials destined to be transformed into a given product plus waste its content of available energy will be inversely related to its utility or price in other words the more of its original energy that has been dissipated the higher its price this means that production i e the dissipation of resources will continuously be rewarded with ever more resources to dissipate generating ecological destruction and global core periphery inequalities as two sides of the same coin

how important is financial risk we explore the determinants of equity price risk of nonfinancial corporations operating and asset characteristics are by far the most important determinants of risk for the median firm financial risk accounts for only 15 of observed stock price volatility furthermore financial risk has declined over the last 3 decades indicating that any upward trend in equity volatility was driven entirely by economic risk factors this explains why financial distress as opposed to economic distress was surprisingly uncommon in the nonfinancial sector during the 2007 2009 crisis even as measures of equity volatility reached unprecedented highs

choosing the precision of performance metrics there is a standard trade off in compensation contracts between the provision of incentives and insurance we hypothesize that this trade off influences the precision with which firm performance is measured we find that firm outcomes are measured less precisely when chance plays a large role in these outcomes further this precision is determined through the choice of shares outstanding this has several novel implications nominal stock prices can remain constant over time and firms with unpredictable cash flows should have more shares and lower stock price levels all else equal we find evidence consistent with these implications

price based return comovement abstract similarly priced stocks move together stocks that undergo splits experience an increase in comovement with low priced stocks and a decrease in their comovement with high priced stocks price based comovement is not explained by economic fundamentals firm size or changes in liquidity or information diffusion the shift in comovement following splits is greater for large stocks high priced stocks and when investor sentiment is high in the full cross section price based portfolios explain variation in stock level returns after controlling for movements in the market and industry portfolios as well as portfolios based on size book to market transaction costs and return momentum the results suggest that investors categorize stocks based on price

reconsidering the initial allocation of itqs the search for a pareto safe allocation between fishing and processing sectors advancement of rights based fishing is stymied by industry and congressional concern over distributional issues arising out of traditional itq design this paper examines the existence and policy feasibility of two alternative initial allocations intended to leave the two principal industry participants the fishers and processors no worse off while maximizing efficiency market structure is shown to be a critical consideration not only to avoid unintended wealth redistribution but also to achieve efficiency

india s biophysical economy 1961 2008 sustainability in a national and global context india s economic growth in the last decade has raised several concerns in terms of its present and future resource demands for materials and energy while per capita resource consumption is still extremely modest but on the rise its sheer population qualifies india as a fast growing giant with material and energy throughput that is growing rapidly if such national and local trends continue the challenges for regional national as well as global sustainability are immense in terms of future resource availability social conflicts pressure on land and ecosystems and atmospheric emissions using the concepts of social metabolism and material flow analysis this paper presents an original study quantifying resource use trajectories for india from 1961 up to 2008 we argue for india s need to grow in order to be able to provide a reasonable material standard of living for its vast population to this end the challenge is in avoiding the precarious path so far followed by industrialised countries in europe and asia but to opt for a regime shift towards sustainability in terms of resource use by building on a host of promising examples and taking opportunities of existing niches to make india a trendsetter

comovement information production and the business cycle abstract recent theoretical research suggests that information production is a positive externality of aggregate economic activity veldkamp 2005 both the quantity and quality of information increase during periods of economic expansion and decrease during periods of contraction based on this insight we hypothesize and confirm that time varying information production drives the comovement patterns observed in stock returns we examine stock return comovement in 36 countries from 1980 to 2007 and show that consistent with the theory comovement patterns are countercyclical that is when information production is high low comovement is low high we also find that the relation between comovement and the business cycle is stronger in countries that experience large intertemporal swings in information production finally we show that the relation between business cycle and comovement is stronger in poor countries countries with less developed financial markets and countries with weaker accounting and transparency standards these results suggest that financial development and transparency are conducive to a steady flow of financial information over the business cycle

why have measures of earnings quality changed over time the properties of earnings have changed dramatically over the past 40 years prior studies interpret this trend as a decline in earnings quality but disagree on whether it results from changes in the real economy or changes in accounting standards i find that each new cohort of listed firms exhibits lower earnings quality than its predecessors mainly because of higher intangible intensity i conclude that the trend of decline in earnings quality is due more to changes in the sample of firms than to changes in generally accepted accounting principles gaap or in the earnings quality of previously listed firms

changes in the standard and poor s 500 list l harris and e gurel 1986 and a shleifer 1986 examined changes in the standard and poor s list both studies presented evidence inconsistent with efficient markets looking at newer data and at bond and option prices the authors find that case against market efficiency is not compelling copyright 1991 by university of chicago press

institutional ownership and changes in the s p 500 several recent articles have provided new evidence for the existence of price pressures by examining the price and volume effects associated with changes in the s p 500 the present study extends this work by examining actual changes in institutional holdings following both additions to and deletions from the s p 500 the results show that changes in institutional holdings in response to additions or deletions from the s p 500 are positively correlated in addition to providing further evidence for the existence of price pressure effects the results also provide evidence of the very large institutional elasticities of demand for stock in two recent articles in this journal shleifer 1986 and harris and gurel 1986 present important new evidence of the existence of price pressures by examining the price and volume effects associated with changes in the composition of the standard and poor s s p 500 market index specifically these authors interpret the strong increases in trading volume and economically and statistically significant increases decreases in share prices on the first trading day following additions to or deletions from the s p 500 as the result of increased decreased demand by institutional index funds rather than from information effects concerning the future return distributions of the newly listed delisted firms the results of similar price and volume studies conducted by woolridge and ghosh 1986 and lamoureux and wansley 1987 are also generally consistent with the predictions of the price pressure hypothesis while both schleifer 1986 and harris and gurel 1986 suggest that changes in institutional index fund holdings are responsible for the observed abnormal returns in response to s p 500 changes over the years between 1966 and 1983 their joint failure to examine actual institutional ownership changes following listing or delisting from the index does not allow for direct tests of this possibility this study presents results of such tests

unraveling the multiple margins of rent generation from individual transferable quotas individual transferable quotas itqs induce changes along both the extensive margin via consolidation of quota among fewer vessels and the intensive margin as harvesters adjust their behavior to itq incentives we use itq introduction in the bering sea crab fishery to decompose the sources of rent generation across both margins we embed an empirically calibrated structural model of the harvesting process into a sector level model allowing us to experimentally unravel the itq treatment we show that the magnitude and source of rent generation under itqs critically depends on the manner and degree of rent dissipation before itqs are implemented

the dartboard column second hand information and price pressure this study analyzes the effect of second hand information on the behavior of security prices and volume using analysts recommendations published in the monthly dartboard column of the wall street journal for the two days following the publication of the recommendations average positive abnormal returns of 4 percent nearly twice the level of abnormal returns documented in previous research on analyst recommendations and average volume double normal volume levels on the two days following publication of the recommendations are documented the positive abnormal return on announcement is partially reversed within 25 trading days the authors conclude that the positive abnormal return on announcement of the recommendations is a result of naive buying pressure as well as the information content of the analysts recommendations

the biophysical perspective of a middle income economy material flows in mexico abstract we analyse natural resource use dynamics in the mexican economy during the last three decades despite low and uneven economic growth the extraction and use of materials in the mexican economy has continuously increased during the last 30 years in this period population growth rather than economic growth was the main driving force for biophysical growth in addition fundamental changes have taken place in the primary sectors in manufacturing and in household consumption and these are reflected in an increasing emphasis on the use of fossil fuels and construction materials mexico s economy has been strongly influenced by international trade since the country commenced competing in international markets in the 1970s mexico mainly exported primary resources this pattern has changed and manufactured goods now have a much greater importance due to a boom in assembling industries in contrast with other latin american countries mexico has achieved a diversification of production moving towards technology intensive products and a better mix in its export portfolio however crude oil exports still represent the single most important export good mexico s material consumption is still well below the oecd average but is growing fast and the current resource use patterns may well present serious social and environmental problems to the medium and long term sustainability of mexico s economy and community information on natural resource use and resource productivity could provide valuable guidance for economic policy planning in mexico

stock price effects and costs of secondary distributions abstract this study does not support the view that a large number of shares can be sold at the prevailing market price and at a small cost a significant stock price decrease is observed at the initial announcement of secondary distributions the price declines are greater for offerings by officers and directors and for larger offerings but are significant for all types of sellers and for large and small offerings there is no significant price decline at the offering when secondaries are announced in advance underwriting and other selling costs are substantial and are positively related to relative offering size

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

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

political foundations of the resource curse in this paper we argue that the political incentives that resource endowments generate are the key to understanding whether or not they are a curse we show 1 politicians tend to over extract natural resources relative to the efficient extraction path because they discount the future too much and 2 resource booms improve the efficiency of the extraction path however 3 resource booms by raising the value of being in power and by providing politicians with more resources which they can use to influence the outcome of elections increase resource misallocation in the rest of the economy 4 the overall impact of resource booms on the economy depends critically on institutions since these determine the extent to which political incentives map into policy outcomes countries with institutions that promote accountability and state competence will tend to benefit from resource booms since these institutions ameliorate the perverse political incentives that such booms create countries without such institutions however may suffer from a resource curse

does product complexity matter for firms output volatility abstract with this paper we provide the first micro level evidence on the linkage between firm complexity and volatility by defining product complexity a la hausmann and hidalgo 2009 we find that a higher complexity level of a firm s product basket is associated to a reduction of its output fluctuations this evidence is robust to the control for omitted variables sample selection and to the use of alternative volatility and complexity indicators across similar firms active in different sectors and regions both technological factors and product market conditions explain the effect of complexity on volatility however within narrowly defined sectors and locations the complexity volatility nexus fully reflects the role of the human capital content of firms product baskets

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

the environmentalism of the poor revisited territory and place in disconnected glocal struggles abstract in 2002 the year it was published the environmentalism of the poor was one of the first books examining in a multidisciplinary perspective three parallel environmental movements around the world eleven years later we re examine these movements the cult of wilderness the gospel of eco efficiency and the mantra of environmental justice focusing on the increased visibility of struggles representing environmental justice and the environmentalism of the poor even if they are often disconnected from an organizational standpoint glocal manifestations of resistance have emerged since the 1990s today environmental movements assert common values related to place identity and culture activists concepts such as ecological debt environmental justice environmental liabilities land grabbing environmental gentrification corporate accountability climate justice food sovereignty or economic degrowth are the keywords of the networks of the global environmental justice movement at the same time such concepts support the rural and urban movements that remake place for marginalized groups re assert traditional practices and protect territory from contamination land appropriation and real estate speculation some possibilities exist for cooperation between environmental justice and the other varieties of environmentalism here comparative research can help unravel the use of valuation languages different from green economic growth or sustainable development

varying heterogeneity among u s firms facts and implications abstract u s firms stock return volatility rose fivefold from 1971 through 2000 and then reverted to near 1971 levels by 2006 this was driven mainly by a rise and fall in the firm specific rather than systematic component of volatility firm level total factor productivity growth volatility exhibited a similar pattern we hypothesize that firm heterogeneity reflected in firm specific volatility rises as a new general purpose technology gpt propagates across the economy and then ebbs once the gpt is widespread measuring gpt adoption by information technology capital intensity we find robust cross industry empirical evidence supporting the hypothesis

stock price reactions to the wall street journal s securities recommendations this paper examines the impact of the heard on the street hots column of the wall street journal on common stock prices the results of the study indicate that the hots column appears to have an impact on stock prices on the publication day however we also find a smaller but statistically significant impact on two days preceding the pub lication the significant abnormal returns on these days are associated with higher trading volume the reaction of stock prices is symmetric with respect to the buy and sell recom mendations and the impact of single company recommendations is greater than the im pact of the multi company recommendations i introduction the efficient market hypothesis assumes that security prices fully and instantaneously reflect all available information considerable evidence has been accumulated during the past decades in support of the hypothesis the acceptance of the hypothesis has raised questions about the economic value of professional investment advice if the market is efficient then the management of port folios based on these recommendations should not consistently outperform the market why then are investors still willing to pay for this information examples of the advice include low cost financial publications brokerage house rec ommendations and subscription financial newsletters that sell for hundreds of dollars recent studies argue that investment advisors can provide information to investors at a lower cost than the investors cost of information production millon and thakor 1985 develop a model that explains the existence of investment advisory agencies they argue that if the information of investment advisory agencies permits security analysts to share information about common uncertainties that affect the value of firms as a whole such as the return on the market portfolio then investment advisory agencies can produce information more cheaply than individual investors this model is consistent with the study of
