does diversification destroy value evidence from the industry shocks does corporate diversification reduce shareholder value since firms endogenously choose to diversify exogenous variation in diversification is necessary to draw inferences about the causal effect we examine changes in the within firm dispersion of industry investment or diversity we find that exogenous changes in diversity due to changes in industry investment are negatively related to firm value thus diversification destroys value consistent with the inefficient internal capital markets hypothesis measurement error does not cause this finding we also find that exogenous changes in industry cash flow diversity are negatively related to firm value r 2002 elsevier science s a all rights reserved jel classification g34

internal capital markets and the competition for corporate resources this article examines the role of corporate headquarters in allocating scarce resources to competing projects in an internal capital market unlike a bank headquarters has control rights that enable it to engage in winner picking the practice of actively shifting funds from one project to another by doing a good job in the winner picking dimension headquarters can create value even when it cannot help at all to relax overall firm wide credit constraints the model implies that internal capital markets may sometimes function more efficiently when headquarters oversees a small and focused set of projects this article analyzes the process by which internal capital markets channel limited resources to different uses inside a company in so doing it seeks to address two related sets of questions first what is the fundamental economic rationale for creating an internal capital market that is under what circumstances can it make sense to combine several technologically distinct projects under one roof and have them seek funding from corporate headquarters as opposed to setting them up as stand alone companies that each raise external financing on their own second given this rationale what is the optimal size and scope of an internal capital market should headquarters be involved in funding a large number of projects or just a few and should these projects be unrelated to one another or in similar lines of business the answers to both sets of questions flow from the insight that in a credit constrained setting where not all positive npv projects can be financed headquarters can create value by actively reallocating scarce funds across projects for example the cash flow generated by one division s activities may be taken and spent on investment in another division where the returns are higher or alternatively one division s assets may be used as collateral to raise financing that is then diverted to the other division simply put individual projects must compete for the scarce funds and headquarters job is to pick the winners and losers in this competition

ownership concentration and firm performance in emerging markets a meta analysis the literature concerned with relations between ownership concentration and corporate performance in emerging markets presents conflicting theoretical predications and inconclusive empirical results we use meta analytical techniques to integrate the diverse empirical findings and investigate factors contribute to the inconsistencies in the empirical evidence using 419 correlations collected from 42 primary studies of listed corporations in 18 emerging markets heterogeneity tests show that only a small proportion of the variation in reported ownership concentration performance relations can be attributed to sampling error our meta regressions reveal how population differences researchers modeling choices and inadequate treatment of endogeneity explain a large portion of the true heterogeneity after adjusting for these effects we find ownership concentration has negative relation with firm performance across countries our results emphasize the importance of model specification and methods of addressing endogeneity and support further comparative study of the ownership concentration corporate performance relation between countries with seemingly similar corporate governance environments

sources of superior performance market share versus industry effects in the u s brewing industry using financial measures of performance we investigate the sources of value creation in the u s brewing industry between 1969 and 1979 we find that market share gains in this industry at this time are not correlated with changes in value and that the performance of individual leading firms is highly correlated our interpretation is that the success of market share building strategies depends critically on specific industry conditions specifically in the absence of fundamental shifts in the relative resource positions of individual firms share gains may come at too high a price in addition the research shows that intra industry correlations in returns may result from excessive competition rather than collusion

how much does country matter an analysis of firms growth options recent international strategy research emphasizes the importance of understanding the effects of geographic location on firms strategies and performance outcomes we contribute to this research by providing empirical evidence that the interplay of country and industry effects matters substantially in explaining the variation in the value of growth options of firms based in different countries our results show that country industry effects are the second largest source of variation following firm effects while industry and country effects are relatively small when considered in their own right that valuable growth options are tied to country and industry interactions has important implications for international strategy research and practice

information technology effects on firm performance as measured by tobin s q despite increasing anecdotal evidence that information technology it assets contribute to firm performance and future growth potential of firms the empirical results relating it investments to firm performance measures have been equivocal however the bulk of the studies have relied exclusively on accounting based measures of firm performance which largely tend to ignore it s contribution to performance dimensions such as strategic flexibility and intangible value in this paper we use tobin s q a financial market based measure of firm performance and examine the association between it investments and firm q values after controlling for a variety of industry factors and firm specific variables the results based on data from 1988 1993 indicate that in all of the five years the inclusion of the it expenditure variable in the model increased the variance explained in q significantly the results also showed that for all five years it investments had a significantly positive association with tobin s q value our results are consistent with the notion that it contributes to a firm s future performance potential which a forward looking measure such as the q is better able to capture

quantifying the effects of uncertain climate and environmental policies on investments and carbon emissions a case study of chile abstract in this article we quantify the effect of uncertainty of climate and environmental policies on transmission and generation investments as well as on co2 emissions in chile we use a two stage stochastic planning model with recourse or corrective investment options to find optimal portfolios of infrastructure both under perfect information and uncertainty under a series of assumptions this model is equivalent to the equilibrium of a much more complicated bi level market model where a transmission planner chooses investments first and generation firms invest afterwards we find that optimal investment strategies present important differences depending on the policy scenario by changing our assumption of how agents will react to this uncertainty we compute bounds on the cost that this uncertainty imposes on the system which we estimate ranges between 3 2 and 5 7 of the minimum expected system cost of 57 6b depending on whether agents will consider or not uncertainty when choosing investments we also find that if agents choose investments using a stochastic planning model uncertain climate policies can result in nearly 18 more co2 emissions than the equilibrium levels observed under perfect information our results highlight the importance of credible and stable long term regulations for investors in the electric power industry if the goal is to achieve climate and environmental targets in the most cost effective manner and to minimize the risk of asset stranding

regulating horizontal diversification abstract this paper investigates the optimal design of diversification rules for regulated enterprises diversification generates profit in non core markets that can be shared with core customers however a diversified firm may divert its attention and effort to non core operations causing consumer welfare in core markets to decline diversification generally results in lower prices and higher powered reward structures in core markets surprisingly diversification is not always directed into the non core markets where the expected contribution of the regulated firm is most pronounced furthermore diversification may be permitted more often as the potential losses from effort diversion increase

gains from an integrated market for tradable renewable energy credits abstract decoupling the environmental attributes of renewable energy re generation from the physical unit of energy is an innovative mechanism for marketing green or renewable power the introduction of tradable renewable energy credits trecs allows the green power attributes of energy to be sold or traded separately from the physical unit of energy since the green power certificate system removes potential locational and physical bottlenecks both suppliers and consumers gain flexibility in the marketplace the trec is also an efficient tool to meet renewable portfolio standard rps required by different states in the us this paper discusses the rps requirements for different states and examines the implications of an integrated trec market it offers a competitive setting to the consumers to pay for renewable energy and a cost effective tool to support renewable energy generation grace and wiser 2002 this paper also highlights some practical difficulties that should be addressed in order to establish an efficient integrated trec market

an engineering economic approach to transmission planning under market and regulatory uncertainties wecc case study we propose a stochastic programming based tool to support adaptive transmission planning under market and regulatory uncertainties we model investments in two stages differentiating between commitments that must be made now and corrective actions that can be undertaken as new information becomes available the objective is to minimize expected transmission and generation costs over the time horizon nonlinear constraints resulting from kirchhoff s voltage law are included we apply the tool to a 240 bus representation of the western electricity coordinating council and model uncertainty using three scenarios with distinct renewable electricity mandates emissions policies and fossil fuel prices we conclude that the cost of ignoring uncertainty the cost of using naive deterministic planning methods relative to explicitly modeling uncertainty is of the same order of magnitude as the cost of first stage transmission investments furthermore we conclude that heuristic rules for constructing transmission plans based on scenario planning can be as suboptimal as deterministic plans

does corporate strategy matter a revisionist view that corporate strategy does not matter has gained considerable influence in recent years this view largely stems from empirical results of early variance decomposition studies that found negligible corporate effects associated with profitability differences between businesses our analysis of the variance decomposition literature shows this view to be incorrect not only do the studies as a group show that factors at the corporate level of organizations contribute to profitability differences but also evidence suggests that factors specifically associated with corporate strategy contribute to corporate effects corporate strategy in fact does matter copyright 2001 john wiley sons ltd

impact of information technology capital on firm scope and performance the role of asset characteristics this research draws on transaction cost and resource based theory to examine how information technology it capital moderates the relationship between different types of assets and firm scope both vertical integration and diversification the analysis suggests that it capital enables firms with narrowly valuable assets to be less vertically integrated and less diversified and enables firms with broadly valuable assets to be more vertically integrated and more diversified the moderating influence of it capital on the relationship between different types of assets and firms vertical and product market scope is consistent with transaction cost as well as resource based traditions abstract from author

the political economy of israeli protectionism an empirical analysis the aim of this study was to examine the tariff structure in israel in terms of the four main theoretical models of endogenous commercial policy the empirical results for levels of protection in israel support several of the models in particular the pressure group model performs well and especially the variable that represents the lobbying power of the histadrut public sector in israel this is consistent with the longstanding political power of the histadrut in israel the histadrut s role in the israeli economy rises above the western concept of a labor union and takes on a quasi governmental function the clearest example of this elevated status is seen when the government included the histadrut as part of the commission charged with the responsibility of carrying out the nominal liberalization process of the 1960s evidently it is this kind of political economic power that allowed the histadrut to affect the level of protection histadrut dominated industries received

distinction between intermediate and finished products in intra firm trade abstract although intra firm trade has been viewed as associated with vertical integration which exploits opportunities for exchange between inherently dissimilar economies it is more common between developed countries where horizontal integration is expected to dominate using unique data from 1974 to 1990 on swedish firms application of a tobit model explains variations in majority owned manufacturing affiliates internal imports of intermediate and finished goods on the basis of firms international organization of production effects which are unobservable in aggregate figures show up only when finished and intermediate goods are separated

are group affiliated firms really more profitable than nonaffiliated the role of corporate center in influencing the economic performance of business units has been a central research topic in the industrial organization and strategic management literature a common finding is the limited corporate and business group effects recently an emerging line of studies argues that the market inefficiencies and institutional voids in emerging markets can be overcome more efficiently by large diversified business groups than by non group small firms some empirical evidence also shows that non group small firms are significantly less profitable than group affiliated firms this paper raises this issue by empirically investigating the influence of group affiliation on the return on assets and tobin s q of 340 group affiliated firms versus 423 non group firms in taiwan during the period of 1997 1999 the statistical results show that group affiliation can not always create value for member firms the size of the business group matters when affiliated with the largest business groups member firms indeed show improved stock market performance but when firms are affiliated with small and medium sized groups their accounting performance suffers findings of this paper suggest a threshold effect and a u shape relationship between group affiliation and profitability in emerging economies

is tourism firm competitiveness driven by different internal or external specific factors new empirical evidence from spain abstract the quest to understand the multilevel antecedents of competitiveness has led to a separation of approaches on one side of the question are the environment theories that analyze the structural characteristics of the general and competitive environment on the other side are the resource based view and its extensions that highlight firm specific resources and capabilities as the main basis of firms competitiveness however in recent years the nature of competition and shifting economic conditions have given rise to new theoretical approaches that complement the assumptions underlying both environmental and firm theories specifically this study contributes by examining the regional environment effect the district effect and the strategic group effect through a study of 364 spanish tourism firms this research explores the relative importance of distinct external forces such as the general environment or country effect the regional effect the competitive environment or industry effect the district effect and internal factors such as the firm s tangible resources capabilities and strategy selection the results demonstrate that firms capabilities are more important than environment effects and tangible resources

diversification diseconomies of scope and vertical contracting evidence from the taxicab industry this paper studies how firms reorganize following diversification proposing that firms use outsourcing or vertical disintegration to manage diseconomies of scope we also consider the origins of scope diseconomies showing how different underlying mechanisms generate contrasting predictions about the link between within firm task heterogeneity and the incentive to outsource following diversification we test these propositions using microdata on taxicab and limousine fleets from the economic census the results show that taxicab firms outsource by shifting the composition of their fleets toward owner operator drivers when they diversify into the limousine business the magnitude of the shift toward driver ownership is larger in less urban markets where the tasks performed by taxicab and limousine drivers are more similar these findings suggest that 1 firms use outsourcing to manage diseconomies of scope at a particular point in the value chain and 2 interagent conflicts can be an important source of scope diseconomies

impact of forecast errors on expansion planning of power systems with a renewables target abstract this paper analyzes the impact of production forecast errors on the expansion planning of a power system and investigates the influence of market design to facilitate the integration of renewable generation for this purpose we propose a programming modeling framework to determine the generation and transmission expansion plan that minimizes system wide investment and operating costs while ensuring a given share of renewable generation in the electricity supply unlike existing ones this framework includes both a day ahead and a balancing market so as to capture the impact of both production forecasts and the associated prediction errors within this framework we consider two paradigmatic market designs that essentially differ in whether the day ahead generation schedule and the subsequent balancing re dispatch are co optimized or not the main features and results of the model set ups are discussed using an illustrative four node example and a more realistic 24 node case study

international organization of production and variation in exports from affiliates there is no simple relationship between internationalization of firms operations and expanding trade the variation in exports from swedish affiliates is here shown to be influenced by properties related to their degree of vertical and horizontal integration affiliates propensity to export is positively affected by production in few countries intermediate imports from the parent plant size income level of the host country and a location in the european community and is negatively affected by r d intensity and the size of the host country market

the effects of firm size and industry on corporate giving recent downward trends in corporate giving have renewed interest in the factors that shape corporate philanthropy this paper examines the relationships between charitable contributions firm size and industry improvements over previous studies include an irs data base that covers a much broader range of firm sizes and industries as compared to previous studies and estimation using an instrumental variable technique that explicitly addresses potential simultaneity between charitable contributions and profitability important findings provide evidence of a cubic relationship between charitable giving and firm size and evidence of strong industry effects the plus minus plus regression coefficient sign pattern for the cubic firm size model suggests that small and large firms give more relative to total receipts with lower giving ratios among medium size firms one interpretation for this finding is that small firms are close to the communities they serve while high visibility creates a need for large firm philanthropy strong industry effects provide evidence of inter industry differences in giving culture and or different public relations requirements across industries

knowledge sources patent protection and commercialization of pharmaceutical innovations abstract this paper investigates different types of innovations from radical to incremental in the pharmaceutical industry by studying bibliometric data of drugs approved by the united states food and drug administration fda looking at time to market aspects knowledge sources of these innovations and protection strategies scientific knowledge stemming from the public sector is found to be important for all innovations nevertheless radical innovations build on a higher degree on basic research and they build on a significantly higher share of own prior scientific research than do incremental innovations furthermore each drug is shown to be accompanied by on average about 19 journal publications and 23 additional patents additional patent filings peak when the commercialization of the drug is in reach firms do not differ among the various types of innovations regarding the amount of additional patent filings but rather with the speed of filing these patents finally this work contributes to the improvement of future econometric analyses that aim to link bibliometric indicators such as patent or publication counts to firm success

the danish green certificate system some simple analytical results we formulate a simple static equilibrium model for the electricity market taking account of both green certificates and co2 emission permits the objective is to investigate the relationship between these markets under the existence of upper and lower price bounds on the green certificates both in the short and in the long run we perform various comparative static changes of the parameters of the model and study how these affect the endogenous variables of the model as well as producers and consumers surplus we also investigate the effects of imports and exports of electricity several comparative static results are derived and in particular it is shown that harsher co2 emission constraints and increased import wholesale price both may lead to reduced capacity of green electricity

he who has the pipeline calls the tune russia s energy power against the background of the shale revolutions abstract russian energy policy is usually considered in the regional context in terms of its energy power capability and strength vis a vis the eu and the post soviet states this study shows that in order to understand russia s energy power even in the regional context of its relations with the eu it is necessary to consider the impact of international changes in the energy sector the oil and gas shale revolutions represent such a global factor of influence even if their consequences are not yet clear they have already become an important challenge for russian energy policy and power this policy oriented article guided by neoclassical realism analyzes what the shale revolutions mean for russia s energy policy and its power capabilities vis a vis the eu how the russian political elite perceive this development and how russia reacts to it in this context russian power capabilities look more moderate

the diversification and financial performance of us credit unions abstract for us credit unions revenue from non interest sources has increased significantly in recent years we investigate the impact of revenue diversification on financial performance for the period 1993 2004 the impact of a change in strategy that alters the share of non interest income is decomposed into a direct exposure effect reflecting the difference between interest and non interest bearing activities and an indirect exposure effect which reflects the effect of the institution s own degree of diversification on both risk adjusted and unadjusted returns measures a positive direct exposure effect is outweighed by a negative indirect exposure effect for all but the largest credit unions this may imply that similar diversification strategies are not appropriate for large and small credit unions small credit unions should eschew diversification and continue to operate as simple savings and loan institutions while large credit unions should be encouraged to exploit new product opportunities around their core expertise

fire sale fdi or business as usual motivated by a set of stylized facts we develop a model of cross border mergers and acquisitions ma 2 the proportion of foreign acquisitions in the same industry is lower 3 the average size of ownership stakes is lower and 4 the duration of acquisitions is lower i e acquisition stakes are more likely to be flipped we find support for 1 but not for the other three predictions the results thus suggest that foreign acquisitions in emerging markets do not differ in these important ways between crisis and normal periods

retail philanthropy firm size industry and business cycle this article investigates the effects of firm size profitability industry affiliation and the business cycle on retailer philanthropy the importance of industry and firm effects on giving was analyzed with regression models using industry fixed effects as well as firm strategy variables the analysis included instrumental variables methodology to account for simultaneity in the charitable giving profits relationship data were gathered from the irs corporate statistics of income sourcebook data that provide firm size class measures covering the entire firm size distribution ranging from small retailers up to large multi national retail firms retailer philanthropy was measured as the ratio of charitable contributions to total receipts important findings include a cubic relationship between retailer philanthropy and firm size industry effects stronger than those observed for retail profit and the absence of business cycle effects the empirical research relating retail charitable giving to firm attributes including firm size and advertising industry and business cycle factors are unique in the business ethics literature prior studies regarding the importance of industry on charitable giving utilized data across broad sectors of the economy firms from different sectors could be expected to differ in philanthropic approach due to differences in public contact as well as differences in public relations exposure the strong industry effects reported for this sample of exclusively retail firms with similar public contact provide strong evidence for the importance of industry in determining firms charitable strategies

electricity and markets over the last fifteen years an increasing number of electricity industries have replaced vertical integration with markets as the main method of organising production electrical energy is traded in many european and us markets while the us also has markets for generating capacity us generators can reduce the cost of complying with environmental regulations by trading emissions of sulphur dioxide while europe has just started a carbon dioxide emissions trading scheme this article discusses the way in which these markets put economic principles into practice in particular it shows that several different market designs can provide theoretically equivalent incentives for generators to build capacity and that emissions trading may have unexpected impacts upon electricity prices

deconstructing the energy weapon russia s threat to europe as case study abstract as the likelihood increases that russia will dominate the european union s eu energy supply questions have emerged as to whether russia would use the energy weapon to influence eu member policies and extract political concessions countervailing voices argue that russia would be restricted by interdependence and market forces as of yet no one has analyzed the assumptions underlying the energy weapon thesis moreover many scholars examining eu russian energy relations rely on non russian data this article seeks to fill several informational and theoretical gaps by including russian sources and first hand data and by systematically analyzing the conditions that must obtain before an energy supplier can successfully convert its energy resources into political power the resulting model can be utilized to analyze the capacity of a supplier to use the energy weapon whether it be russia iran venezuela or any other energy heavyweight and to assess whether the deployment was successful five purported cases of russian manipulation are analyzed in this article and the findings indicate that more often than not russia failed to achieve political concessions looking to the future the plausibility of russia using the energy weapon to exploit europe s dependence particularly on gas is also examined

cvar constrained planning of renewable generation with consideration of system inertial response reserve services and demand participation abstract integration of renewable generation can lead to both diversification of energy sources which can improve the overall economic performance of the power sector and cost increase due to the need for further resources to provide flexibility and thus secure operation from unpredictable variable and asynchronous generation in this context we propose a cost risk model that can properly plan generation and determine efficient technology portfolios through balancing the benefits of energy source diversification and cost of security of supply through the provision of various generation frequency control and demand side services including preservation of system inertia levels we do so through a scenario based cost minimization framework where the conditional value at risk cvar associated with costs under extreme scenarios of fossil fuel prices combined with hydrological inflows is constrained the model can tackle problems with large data sets e g 8760 hours and 1000 scenarios since we use linear programming and propose a benders based method adapted to deal with cvar constraints in the master problem through several analyses including the chilean main electricity system we demonstrate the effects of renewables on hedging both fossil fuel and hydrological risks effects of security of supply on costs risks and renewable investment and the importance of demand side services in limiting risk exposure of generation portfolios through encouraging risk mitigating renewable generation investment

neoclassical realism and theories of foreign policy although international relations theory has been dominated for two decades by debates over theories of international politics recently there has been a surge of interest in theories of foreign policy these seek to explain not the pattern of outcomes of state interactions but rather the behavior of individual states the author surveys three prominent theories of foreign policy and shows how the works under review set out a compelling alternative one that updates and systematizes insights drawn from classical realist thought neoclassical realism argues that the scope and ambition of a country s foreign policy is driven first and foremost by the country s relative material power yet it contends that the impact of power capabilities on foreign policy is indirect and complex because systemic pressures must be translated through intervening unit level variables such as decision makers perceptions and state structure understanding the links between power and policy thus requires close examination of both the international and the domestic contexts within which foreign policy is formulated and implemented

tobin s q and the importance of focus in firm performance using tobin s q as a measure of performance we seek to estimate the relative importance of industry focus and share effects in determining firm performance our methods are analogous to those of richard schmalensee and like him we find that industry effects account for the majority of the explained variance however we also find that firm effects exist in the form of focus effects that is narrowly diversified firms do better than widely diversified firms we interpret this finding as consistent with profit maximization by firms with different factor endowments

estimating the performance effects of business groups in emerging markets business groups confederations of legally independent firms are ubiquitous in emerging economies yet very little is known about their effects on the performance of affiliated firms we conceive of business groups as responses to market failures and high transaction costs in doing so we develop hypotheses about the effects of group affiliation on firm profitability affiliation could either boost or depress firm profitability and members of a group are likely to earn rates of return similar to other members of the same group using a unique data set compiled largely from local sources we test for these effects in 14 emerging markets argentina brazil chile india indonesia israel mexico peru the philippines south africa south korea taiwan thailand and turkey we find evidence that business groups indeed affect the broad patterns of economic performance in 12 of the markets we examine group affiliation appears to have as profound an effect on profitability as does industry membership yet strategy scholars have a much clearer grasp of industries than of groups moreover membership in a group raises the profitability of the average group member in several of the markets we examine this runs contrary to the wisdom conventional in advanced economies that unrelated diversification depresses profitability overall our findings suggest that the roots of sustained differences in profitability may vary across institutional contexts conclusions drawn in one context may well not apply to another copyright 2001 john wiley sons ltd

does board gender diversity influence financial performance evidence from spain in recent years several countries have enacted guidelines and or mandatory laws to increase the presence of women on the boards of companies through these regulatory interventions the aim is to eradicate the social and labor grievances that women have traditionally experienced and which has relegated them to smaller scale jobs nevertheless and despite the advances achieved the female representation in the boardroom remains far from the desired levels in this context it is now necessary to enhance the advantages of board gender diversity from both ethical and economic points of view this article examines the relation between board gender diversity and economic results in spain the second country in the world to legally require gender quotas in boardrooms and historically characterized by a minimal female participation in the workforce based on a sample of 125 non financial firms listed on the madrid stock exchange from 2005 to 2009 our findings show that in the period analyzed the increase of the number of women on boards was over 98 this suggests that compulsory legislation offers an efficient framework to execute the recommendation of spanish codes of good governance by means of the increase in the number of women in the boards of firms furthermore we find that the increase in the number of women on the boards is positively related to higher economic results therefore both results suggest that gender diversity in boardrooms should be incremented mandatory laws being a key factor to do so

the persistence of shocks to profitability in this study we use data for 1981 through 1994 on a large sample of u s companies to examine the persistence of incremental industry corporate parent and business specific effects on profitability our results indicate that the incremental effects of industry on profitability persist longer than the incremental effects of the corporate parent and of the specific business changes in industry structure have a more persistent impact on profitability than do changes in firm structure

q and the tax bias theory abstract a growing body of literature analyzes the variation in q the ratio of financial market value to asset current replacement cost and makes inferences about attributes such as monopoly power profitability managerial performance etc these studies ignore potential biases embedded in q that result from non neutral tax policies this study examines the association between q and tax biases and establishes that differences in accumulated depreciation tax shields explain significant variation in q the implication that q should be adjusted for tax biases before use in empirical research is examined further adjusting q for tax biases at least with the factors herein leads only to minor changes in econometric analyses

competencies and firm performance examining the causal ambiguity paradox resource based theory argues that resources must be valuable rare inimitable and lack substitutes to confer competitive advantage inimitability is a lynchpin of resource based theory and central to understanding the sustainability of competitive advantage although scholars recognize a positive relationship between causal ambiguity and inimitability the relationship among critical resources called competencies causal ambiguity and firm performance remains an unresolved conundrum one perspective suggests that causal ambiguity regarding competencies and performance is necessary among internal and external managers for sustainable competitive advantage because it severely limits imitation causal ambiguity therefore enhances firm performance another view holds that causal ambiguity places a constraint on the transfer and leveraging of these competencies within a firm in this case causal ambiguity may adversely influence firm performance this paper takes a resource based view to develop and test hypotheses that relate managers perceptions of causal ambiguity to their firm s performance the hypotheses examine relationships between firm performance and 1 causal ambiguity regarding the link between competencies and competitive advantage and 2 causally ambiguous characteristics of competencies research involving 224 executives in 17 organizations provides valuable insights into the relationships between causal ambiguity and firm performance a model is then developed based on these findings particular consideration is given to the differing ways top and middle managers in a firm may experience causal ambiguity and to how these differences may be understood and managed copyright 2001 john wiley sons ltd

gender diversity in the boardroom and firm financial performance the monitoring role performed by the board of directors is an important corporate governance control mechanism especially in countries where external mechanisms are less well developed the gender composition of the board can affect the quality of this monitoring role and thus the financial performance of the firm this is part of the business case for female participation on boards though arguments may also be framed in terms of ethical considerations while the issue of board gender diversity has attracted growing research interest in recent years most empirical results are based on u s data this article adds to a growing number of non u s studies by investigating the link between the gender diversity of the board and firm financial performance in spain a country which historically has had minimal female participation in the workforce but which has now introduced legislation to improve equality of opportunities we investigate the topic using panel data analysis and find that gender diversity as measured by the percentage of women on the board and by the blau and shannon indices has a positive effect on firm value and that the opposite causal relationship is not significant our study suggests that investors in spain do not penalise firms which increase their female board membership and that greater gender diversity may generate economic gains

economic fluctuations market power and returns to scale evidence from firm level data recent research on aggregate fluctuations coupled with ongoing work in industrial organization has renewed interest in the existence magnitude and cyclical pattern of market power and the extent of increasing returns to scale by exploiting restrictions from dynamic theory and information from financial markets we present a framework for generating quantitative evidence on market power and returns to scale tailoring the econometric model to firm level panel data we calculate the percentage differential between price and marginal cost the lerner index in terms of the parameters from the econometric system results for firms in eleven industries indicate that there is a great deal of heterogeneity in the extent of market power industries with significantly positive lerner indices tend to have substantial increasing returns in the production technology we find that there is only a modest relation between our estimated lerner indices and traditional measures of market power and that when market power varies temporally it is usually procyclical thus variations in the markup of price over marginal cost may help dampen aggregate economic fluctuations

high resolution modeling of the western north american power system demonstrates low cost and low carbon futures decarbonizing electricity production is central to reducing greenhouse gas emissions exploiting intermittent renewable energy resources demands power system planning models with high temporal and spatial resolution we use a mixed integer linear programming model switch to analyze leastcost generation storage and transmission capacity expansion for western north america under various policy and cost scenarios current renewable portfolio standards are shown to be insufficient to meet emission reduction targets by 2030 without new policy with stronger carbon policy consistent with a 450 ppm climate stabilization scenario power sector emissions can be reduced to 54 of 1990 levels by 2030 using different portfolios of existing generation technologies under a range of resource cost scenarios most coal power plants would be replaced by solar wind gas and or nuclear generation with intermittent renewable sources providing at least 17 and as much as 29 of total power by 2030 the carbon price to induce these deep carbon emission reductions is high but assuming carbon price revenues are reinvested in the power sector the cost of power is found to increase by at most 20 relative to business as usual projections

corporate and industry effects on business unit competitive position we partition the variances of market shares which we use as surrogates for competitive position of the business units of all public manufacturing companies available in the trinet data base into industry factors corporate parent specific factors and business unit specific factors our results differ somewhat from rumelt s 1991 which decomposed variances in profitability we find that corporate parent effects on market share are considerably greater than zero when lines of business are defined more narrowly when small business units are included and when firms are medium sized our results suggest that the relative importance of corporate industry and business unit effects depends on the types of criteria such as the level of industry aggregation whether small business units are included and firm size that are used to construct samples copyright 2000 john wiley sons ltd

new venture strategy and profitability a venture capitalist s assessment abstract this study uses theoretically justified criteria from the industrial organization io strategy literature and applies it to a new domain namely venture capitalists decision making specifically the study investigates the types of information venture capitalists utilize when evaluating new ventures and how venture capitalists use this information to assess likely new venture profitability in the interest of advancing our understanding of the decision making policies of venture capitalists this study addresses many of the limitations of previous research a review of io research suggests important relationships between a number of strategy variables and new venture profitability some of the relationships proposed by io strategy research are contingent in nature the strategy variables and their relationships with profitability are investigated in the domain of venture capitalists decision making individual and aggregate decision making analyses identified those strategy variables criteria venture capitalists utilize in assessing likely new venture profitability namely timing key success factor stability lead time competitive rivalry educational capability industry related competence timing key success factor stability interaction timing lead time interaction and timing educational capability interaction on average the most important criterion for venture capitalists in their assessment of profitability is industry related competence the second tier of importance is competitive rivalry timing and educational capability the third tier of importance is lead time key success factor stability and timing lead time interaction other interactions are less important therefore while venture capitalists use contingent decision policies main effects dominate if venture capitalists use a reported 8 to 12 minutes on average to evaluate a business plan sandberg 1986 then this study s findings may help the inexperienced venture capitalist allocate time towards assessing those attributes of primary importance although more complex relationships exist between the attributes the inexperienced venture capitalist can take comfort from this study s findings that main effects dominant amongst senior venture capitalists senior venture capitalists may take less comfort from their importance placed on main effects in light of research from io which suggests the importance of contingent relationships the results may also have practical application towards training how should venture capital firms train their new employees should venture capital firms rely solely on experienced venture capitalists lecturing the inexperienced on the criteria they use in assessing a new venture proposal like most decision makers venture capitalists have limited insight into their assessments and venture capital firms need to be aware of the gap between espoused policies and policies in use the information being taught needs to be supplemented with venture capitalists decision making research that investigates decision policies in use such as this study venture capitalist training could also involve experiential learning in conjunction with cognitive feedback about the decision policies used to accelerate the learning process experiential learning using cognitive feedback maximizes industry related learning while minimizing the cost of inexperienced decisions for the entrepreneur seeking capital this increased understanding of venture capitalists decision making may help them better target their business plans and presentations at those criteria venture capitalists find most critical to the profitability of a new venture

aiming low and achieving it a long term analysis of a renewable policy in chile abstract we use an integrated resource planning model to assess the costs of meeting a 70 renewables target by 2050 in chile this model is equivalent to a long term equilibrium in electricity and renewable energy certificate rec markets under perfect competition we consider different scenarios of demand growth resource eligibility e g large hydropower and transmission system configuration our numerical results indicate that the sole characteristics of the available renewable resources in the country and reductions in technology costs will provide sufficient economic incentives for private investors to supply a fraction of renewables larger than 70 for a broad range of scenarios meaning that the proposed target will likely remain a symbolic government effort increasing transmission capacity between the northern and central interconnected systems could reduce total system cost by 400 million per year and increase the equilibrium share of nonconventional renewable energy ncre in the system from 45 to 52 without the need for any additional policy incentive surprisingly imposing a 70 of ncre by 2050 results in a rec price lower than the noncompliance fine used for the current target of 20 of ncre by 2025 the latter of which represents the country s maximum willingness to pay for the attributes of electricity supplied from ncre resources

a capability based view of competitive heterogeneity the question of how firms differ is paramount to strategy scholars this question has motivated empirical research on the factors influencing performance differences among close competitors it also has motivated work on factors that increase or decrease the mean performance of firms in an industry theories about resources and capabilities tend to dominate discussions of heterogeneity in performance and superior performance yet the strategy field lacks a cumulative body of empirical work showing how firms differ this article derives conclusions and questions from empirical work on capabilities we then discuss work that complements but lies beyond the boundaries of traditional capabilities research we conclude by suggesting approaches to and areas of future work

does risk aversion affect transmission and generation planning a western north america case study abstract we investigate the effects of risk aversion on optimal transmission and generation expansion planning in a competitive and complete market to do so we formulate a stochastic model that minimizes a weighted average of expected transmission and generation costs and their conditional value at risk cvar we show that the solution of this optimization problem is equivalent to the solution of a perfectly competitive risk averse stackelberg equilibrium in which a risk averse transmission planner maximizes welfare after which risk averse generators maximize profits this model is then applied to a 240 bus representation of the western electricity coordinating council in which we examine the impact of risk aversion on levels and spatial patterns of generation and transmission investment although the impact of risk aversion remains small at an aggregate level state level impacts on generation and transmission investment can be significant which emphasizes the importance of explicit consideration of risk aversion in planning models

the effect of product diversification strategies on the performance of health insurance conglomerates abstractthe conglomerate organizational structure of health insurers suggests two distinct methods of product diversification the first is firm level diversification or diversification within individual affiliates and the second is conglomerate level diversification or diversification across affiliates of the conglomerate we hypothesize that using both firm and conglomerate level diversification may magnify the costs or benefits of diversification on the financial performance of the conglomerate our results confirm this hypothesis and suggest a positive relation between health insurer financial performance and the use of both product line diversification methods our results not only contribute to the body of literature related to corporate diversification but are also important to policymakers and all health insurance market participants as portions of the affordable care act continue to be implemented

the validity of profits structure studies with particular reference to the ftc s line of business data the simple proposition that consumerdamaging collusion is more likely to occur when there are fewer competitors has given rise not only to legal restrictions of economic activity thought to restrict output but also to an enormous amount of empirical work attempting to relate market concentration to the exercise of monopoly power most such studies measured market structure by an index of concentration for example four firm concentration or herfindahl and performance by accounting profit for example net profit divided by assets or price cost margins sales less direct costs divided by sales from the positive statistically significant correlations often found between greater concentration and profit with other factors presumably accounted for some researchers conclude that increases in concentration are anticompetitive and that concentration therefore is bad the concentration profits studies have been criticized essentially on two grounds one is that the positive relationship is not indicative of collusive behavior in particular oliver williamson 1968 john mcgee 1971 harold demsetz 1973 1974 and sam peltzman 1977 point out that higher profits could result from efficiencies experienced by large firms which resulted both in greater market shares and high levels of concentration analytical arguments show that higher profits logically follow as much from lower costs that are associated with higher levels of concentration as from collusion determined higher prices some empirical evidence that supports this belief is presented by demsetz peltzman and bradley gale and ben branch 1982 however their findings have been contested on the grounds that the data used are biased or inadequate or that the researchers have not demonstrated that the observed higher profits greater concentration relationship was caused by lower costs 2 the second criticism is that available data provide an inadequate basis for such conclusions the concentration numbers are based usually on industries defined by the commerce department s standard industrial classifications sic the sic definitions tend to be supply production rather than demand determined include nonhomogeneous products and exclude sales of similar products that are included in different sic groups or are imported the profit data are taken from accounting reports that provide poor measures of economic values weiss 1974 describes many of these problems however he does not believe that these shortcomings invalidate the studies as weiss 1979 concludes

market power in renewable portfolio standards abstract renewable portfolio standard rps which requires a certain percentage of electricity production from renewables has received considerable attention one emerging issue is the possibility of strategic behavior in the renewable energy certificate credit rec market and its spillover effects on the electricity market this paper develops dominant firm competitive fringe models that account for market power we show that market power could have significant impacts on the rec and power prices in particular when a nonrenewable generator is a dominant firm and a renewable generator is a competitive fringe the nonrenewable firm has a strong incentive to lower the rec price even to zero for avoiding rec costs the zero rec price would negate price impacts in the power market thereby mitigating market power of the dominant firm however this could lead to an underinvestment in renewables in the long run as subsidies received by renewables in form of recs vanish therefore regulatory agencies need to carefully oversee the market performance to ensure a healthy development of renewable industries under the rps policies

success in high technology markets is marketing capability critical we propose a conceptual framework with the resource based view rbv of the firm as its theoretical underpinning to explain interfirm differences in firms profitability in high technology markets in terms of differences in their functional capabilities specifically we suggest that marketing r d and operations capabilities along with interactions among these capabilities are important determinants of relative financial performance within the industry this paper contributes to the rbv literature by proposing the input output perspective to conceptualize the notion of capabilities specifically this approach entails modeling a firm s functional activities viz marketing r d and operations as transformation functions that relate the productive factors resources to its functional objectives if the firm were to deploy these resources most efficiently any underattainment of the functional objective then is attributable to functional inefficiency or equivalently to a lower functional capability of the firm the input output conceptualization of a firm s capabilities is then estimated using the stochastic frontier estimation sfe methodology sfe provides the appropriate econometric technique to empirically estimate the efficient frontier and hence the level of efficiency achieved by the various firms our study contributes to a number of literatures both methodologically and substantively first it contributes both conceptually and methodologically to the rbv literature conceptually our study suggests that firm capabilities can be viewed in an input output framework methodologically the study suggests the use of stochastic frontier estimation to operationalize and estimate firm capabilities this methodology is to the best of our knowledge the first to allow the researcher manager to infer capabilities from archival data substantively our study contributes to the literature on market orientation by suggesting that a stronger market orientation of a firm should be reflected in a higher marketing capability it also adds to the literature on design for manufacturability by explicating the complementarity among the various functional capabilities and offering empirical evidence on their relative importance in influencing a firm s performance finally our study builds on prior literature that has highlighted the importance of marketing r d coordination as important determinants of new product development and success we highlight below some of our main findings 1 a strong base of innovative technologies enhances a firm s sales by favorably influencing consumers expectations about the externality benefits associated with its product this suggests that a past track record of consistent innovation is a credible signal to current and potential customers of the firm s continued excellence in a technologically evolving market given the importance of influencing customers managers need to tailor their marketing activities around the need to inform customers of the technological excellence of their firm thus customers need to be informed of the innovative technologies that the firm possesses and of the future r d initiatives undertaken by it similarly any potential applications of innovative technology developed by the firm and of technologies under development should be emphasized 2 marketing capability has its greatest impact on the quality adjusted innovative output for firms that have a strong technological base in other words firms with a strong r d base are the ones with the most to gain from a strong marketing capability 3 marketing capability strongly influences the width of applicability of innovations i e a firm s marketing capability enhances its ability to generate innovative technologies that have applications across a range of industries this result carries a strong message for managers a strong market orientation is one of the most fertile sources of ideas for innovation thus marketing needs to be involved from the beginning of the innovation process namely right at the stage when technological ideas are being generated 5 the most important determinant of a firm s performance is the interaction of marketing and r d capabilities this supports the assertion that firms in high technology markets need to excel at two things the ability to come up with innovations constantly and the ability to commercialize these innovations into the kinds of products that capture consumer needs and preferences this finding offers further evidence on the importance of coordination between r d and marketing as suggested in the extant marketing literature finally using archival data our methodology can be used to benchmark a firm s capabilities with other firms in the industry along various functional dimensions this would be an important step in making more informed resource allocation decisions thus the firm can spend more money on those capabilities where it most lags the competition or on those capabilities that are shown to have the maximum impact on firm performance

the russian oil industry between public and private governance obstacles to international oil companies investment strategies the low level of involvement by international oil companies in russia seems difficult to explain given what development of its resources and production has to offer there are still many restrictions and contradictions born of the particular institutional and political environment of the russian oil industry at the end of 15 years of transition that act as a bar to international integration three factors currently define the establishment of relations with foreign investors first because of the many different levels of negotiation with russian companies the state and the regions the decisions are based on complex relations between the various forces second the reforms and especially privatisation and the allocation of rights of ownership to deposits are considered by sizeable sections of public opinion and many political classes to be illegitimate thus making the issue of international investment and foreign presence still more complicated finally the state s wish to take back the oil industry in order to use it to fulfil its economic and foreign policies is creating further uncertainty these three elements seriously restrict the entry of international oil companies to the russian market

internal versus external capital markets this paper presents a framework for analyzing the costs and benefits of internal versus external capital allocation we focus pritnarily on comparing an internal capital market with bank lending while both represent centralized forms of financing in the former case the financing is owner provided while in the latter ceise it is not we argue that the ownership aspect of internal capital allocation has three important consequences 1 it leads to more monitoring than bank lending 2 it reduces managers entrepreneurial incentives and 3 it makes it easier to efficiently redeploy the assets of projects that are performing poorly under existing management

are internal capital markets efficient using segment information from compustat we find that the investment by a segment of a diversified firm depends on the cash flow of the firm s other segments but significantly less than it depends on its own cash flow the investment by segments of highly diversified firms is less sensitive to their cash flow than the investment of comparable single segment firms the sensitivity of a segment s investment to the cash flow of other segments does not depend on whether its investment opportunities are better than those of the firm s other segments

redefining industry structure for the information age we are entering a new competitive age in which the basis of competition is being fundamentally altered through the introduction of advanced information technologies and public communication infrastructures such as the internet in these environments the nature and locus of competition will radically alter as information becomes an increasingly important resource this paper develops ideas around the strategic characteristics of information information separability and information specificity moreover it attempts to redefine the nature of industry structure in such a competitive environment by examining what constitutes the real boundaries of competition industry concentration related diversification and innovation for firms competing in the information age 1998 john wiley sons ltd

do markets differ much this essay reports the results of a crosssection study of differences in accounting profitability that sheds light on some basic controversies in industrial economics most previous cross section studies in this field have been concerned with testing hypotheses about structural coefficients in models meant to apply to essentially all markets as we have learned more about the difficulties of constructing such general models and of performing tests on their structural parameters properly structural cross section analysis has fallen out of fashion in contrast to most of the cross section literature the analysis reported here is fundamentally descriptive it does not attempt directly to estimate or to test hypotheses about structural parameters i hope to show by example that one can perform illuminating analysis of cross section data without a host of controversial maintained hypotheses cross section data can yield interesting stylized facts to guide both general theorizing and empirical analysis of specific industries even if they cannot easily support full blown structural estimation one can view the sort of search for stylized facts conducted here as either a replacement for or an input to interindustry structural estimation depending on one s feeling about the long run potential of that research approach this study also departs from much of the cross section literature by being fundamentally concerned with the importance of various effects not just with coefficient signs and t statistics in particular this essay provides estimates of the relative importance of firm market and market share differences in the determination of business unit divisional profitability in u s manufacturing using 1975 data from the line of business program of the u s federal trade commission ftc i find support neither for the existence of firm effects nor for the importance of market share effects moreover while industry effects apparently exist and are important they appear to be negatively correlated with seller concentration in these data section i relates firm market and share effects to current issues and controversies in industrial economics and thus supplies the motivation for our empirical analysis the remainder of the essay treats the data and

towards an economic theory of the multiproduct firm this paper outlines a theory of the multiproduct firm important building blocks include excess capacity and its creation market imperfections and the peculiarities of organizational knowledge including its fungible and taut character a framework is adopted in which profit seeking firms are seen to diversify in order to avoid the high transactions costs associated with using various markets to trade the services of various specialized assets neoclassical explanations of the multiproduct firm are shown to be seriously deficient

diversification ricardian rents and tobin s q according to prevailing theory firms diversify in response to excess capacity of factors that are subject to market failure by probing into the heterogeneity of these factors we develop the corollary that firms that elect to diversify most widely should expect the lowest average rents an empirical test with tobin s q as the measure of rents is consistent with this theory

state renewable energy electricity policies an empirical evaluation of effectiveness over the past decade state governments have emerged as us energy policy leaders across the country states are adopting policy instruments aimed at carbon mitigation and renewable energy deployment one of the most prevalent and innovative policy instruments is a renewable portfolio standard rps which seeks to increase the share of renewable energy electrification in the electricity market this analysis evaluates the effectiveness of state energy programs with an empirical investigation of the linkage between state rps policy implementation and the percentage of renewable energy electricity generation across states we use a variant of a standard fixed effects model referred to as a fixed effects vector decomposition with state level data from 1998 to 2006 results indicate that rps implementation is not a significant predictor of the percentage of renewable energy generation out of the total generation mix yet for each additional year that a state has an rps policy they are found to increase the total amount of renewable energy generation these findings reveal a potentially significant shortcoming of rps policies political institutions natural resource endowments deregulation gross state product per capita electricity use per person electricity price and the presence of regional rps policies are also found to be significantly related to renewable energy deployment

between russia as producer and ukraine as a transit country eu dilemma of interdependence and energy security abstract between 2014 and 2015 the eu started a new energy policy in order to address among other issues the problematic character of energy interdependence with russia and thus improve its energy security the aim of this article is to determine how this policy considered interdependence with russia in the light of diversification alternatives energy security is seen through short term and long term dimensions which can be equated to the concepts of vulnerability and sensitivity interdependence as the article shows the alternative of lng is limited by production and consumption patterns in both europe and other world markets it also shows that maintaining interdependence with russia and reducing the role of transit countries such as ukraine would yield benefits both in vulnerability and sensitivity interdependence however while the eu has strongly based its rhetoric on the promise of lng it has ignored alternatives that would maintain interdependence with russia eventually the eu s energy strategy has acknowledged the limitations of lng even though it has not changed its stance towards russia in that respect it seems fair to conclude the eu has not rigorously analysed the transit dimension in its interdependence with russia and the implications for its energy security
