measuring the impacts of teachers i evaluating bias in teacher value added estimates are teachers impacts on students test scores value added a good measure of their quality one reason this question has sparked debate is disagreement about whether value added va measures provide unbiased estimates of teachers causal impacts on student achievement we test for bias in va using previously unobserved parent characteristics and a quasi experimental design based on changes in teaching sta using school district and tax records for more than one million children we nd that va models which control for a student s prior test scores exhibit little bias in forecasting teachers impacts on student achievement although teachers have substantial impacts

shaming the corporation the social production of targets and the anti sweatshop movement as social movements co evolve with changes in states and markets it is crucial to examine how they make particular kinds of actors into focal points for the expression of grievances and the demand for rights but researchers often bracket the question of why some kinds of organizations are more likely than others to become targets of social movement pressure we theorize the social production of targets by social movements rejecting a simple reflection model to focus on configurations of power and vulnerability that shape repertoires of contention empirically we extend structural accounts of global commodity chains and cultural accounts of markets to analyze the production of targets in the case of the anti sweatshop movement of the 1990s using a longitudinal firm level dataset and unique data on anti sweatshop activism we identify factors that attracted social movement pressure to particular companies firms power and positions strongly shaped their likelihood of becoming targets of anti swea

effects of free choice among public schools in this paper i investigate the impact of a programme in tel aviv israel that terminated an existing inter district busing integration programme and allowed students free choice among public schools the identification is based on difference in differences and regression discontinuity designs that yield various alternative comparison groups drawn from untreated tangent neighbourhoods and adjacent cities across identification methods and comparison groups the results consistently suggest that choice significantly reduces the drop out rate and increases the cognitive achievements of high school students it also improves behavioural outcomes such as teacher student relationships and students social acclimation and satisfaction at school and reduces the level of violence and classroom disruption

using maimonides rule to estimate the effect of class size on scholastic achievement the twelfth century rabbinic scholar maimonides proposed a maximum class size of 40 this same maximum induces a nonlinear and nonmonotonic relationship between grade enrollment and class size in israeli public schools today maimonides rule of 40 is used here to construct instrumental variables estimates of effects of class size on test scores the resulting identiecation strategy can be viewed as an application of donald campbell s regression discontinuity design to the class size question the estimates show that reducing class size induces a signiecant and substantial increase in test scores for fourth and efth graders although not for third graders when asked about their views on class size in surveys parents and teachers generally report that they prefer smaller classes this may be because those involved with teaching believe that smaller classes promote student learning or simply because smaller classes offer a more pleasant environment for the pupils and teachers who are in them mueller chase and walden 1988 social scientists and school administrators also have a longstanding interest in the class size question class size is often thought to be easier to manipulate than other school inputs and it is a variable at the heart of policy debates on school quality and the allocation of school resources in many countries see e g robinson 1990 for the united states ofsted 1995 for the united kingdom and moshel ravid 1995 for israel this broad interest in the consequences of changing class size

legitimacy and multi level institutional environments implications for foreign subsidiary ownership structure in this study we examine from an institutional perspective the legitimacy rationale behind the choice of subsidiary ownership structure among multinational corporations mncs we suggest that when under a strong pressure to conform at the host country and local industry levels of their institutional environment mncs are likely to take a lower ownership stake in exchange for external legitimacy in the host country or local industry that their foreign subsidiaries are entering we also suggest that mncs are likely to take a higher ownership stake in response to strong internal pressure to sustain their internal legitimacy at the corporate level of their institutional environment we also propose that mncs are more likely to exchange ownership for legitimacy in local industries than in host countries and in local markets with a high level of political instability than in those with a low level of political instability these propositions are generally supported by our analysis of 4451 subsidiaries established by 898 japanese mncs that operated in 39 countries across 52 industries two digit sic between 1988 and 1999

longer term effects of head start specially collected data on adults in the panel study of income dynamics are used to provide evidence on the longer term effects of head start an early intervention program for poor preschool age children whites who attended head start are relative to their siblings who did not significantly more likely to complete high school attend college and possibly have higher earnings in their early twenties african americans who participated in head start are less likely to have been booked or charged with a crime there is some evidence of positive spillovers from older head start children to their younger siblings language en

density dependence of entrepreneurial dynamics competition opportunity cost or minimum efficient scale this paper reports on a new examination of the well established negative effect of localized density on survival in established industries we attempt to discriminate between three competing but not necessarily mutually exclusive explanations resource competition variations in the opportunity costs of entrepreneurship and geographic variations in minimum efficient scale mes we construct a model of firm growth and survival in which each of these potential causes of density dependence has a transparent parametric effect and we derive six predictions that collectively allow for discriminating empirical tests empirical results using confidential geocoded data from the national longitudinal survey of youth consistently favor the opportunity cost mechanism this paper was accepted by toby stuart entrepreneurship and innovation

the founding of specialist firms in a global fragmenting industry the study examines what drives the founding of specialist firms two theoretical explanations are tested for the founding of specialists density dependence and resource partitioning the study finds that specialists foundings are dependent on the population s density at the global level but not at the united states level the evidence from a fragmented industry does not support the resource partitioning hypothesis either at the global level or the united states national level the study shows how multi level analyses can suggest if an industry is multi domestic or globally integrated

how optimal distinctiveness affects new ventures failure risk a contingency perspective abstract in this article we apply the concept of optimal distinctiveness to test whether category spanning has a nonlinear effect on new ventures risk to fail we argue that by being optimally distinct i e by attaining a level of category spanning that allows new ventures to benefit from balancing the competing needs of conformity with and differentiation from competitors new ventures can improve their survival chances in addition we argue that the relevance of optimal distinctiveness varies with a venture s age and a category s density we tested our hypotheses using data from 1668 metal bands that were founded in the united kingdom between 1967 and 2005 the results indicate that optimal distinctiveness is relevant to new ventures failure risk moreover we show that venture age attenuates the relevance of optimal distinctiveness whereas category density strengthens that factor s relevance

a critical exploration of sponsorship infrastructure and new organizations this research focuses on the effects of public sponsorship and regional infrastructure on the emergence and survival of new organizations propositions are tested regarding the joint effects of sponsorship and infrastructure on industrial development in a randomly selected sample of fourteen regions the data include six measures of infrastructure sponsorship as measured by the total dollars spent for economic development and their individual and joint effects on the number of firms and employees in high technology industries for the years 1965 1970 1975 1980 and 1984 this preliminary analysis suggests that variation in the infrastructure and level of sponsorship within a region is related to the birth and survival of new organizations

biases in standard measures of intergenerational income dependence abstract estimates of the most common mobility measure the intergenerational elasticity can be severely biased if snapshots are used to approximate lifetime income however little is known about biases in other popular dependence measures using long swedish income series we provide such evidence for log linear and rank correlations and rank based transition probabilities attenuation bias is considerably weaker in rank based measures life cycle bias is strongest in the elasticity moderate in log linear correlations and small in rank based measures however there are important exceptions persistence in the tails of the distribution is considerably higher and long distance downward mobility lower than estimates from short run income suggest

the costs of shareholder activism evidence from a sequential decision model abstract this paper provides benchmarks for monitoring costs and evaluates the net returns to shareholder activism i model activism as a sequential decision process consisting of demand negotiations board representation and proxy contest and estimate the costs of each activism stage a campaign ending in a proxy fight has average costs of 10 71 million i find that the estimated monitoring costs reduce activist returns by more than two thirds the mean net activist return is close to zero but the top quartile of activists earns higher returns on their activist holdings than on their non activist investments the large sample evidence presented in this paper aids in understanding the nature and evolution of activist engagements

firm survival and industry evolution in vertically related populations this paper examines how the density and governance of vertically related populations affect the life chances of organizations we integrate the literatures on organizational ecology and vertical integration to develop a theory of how 1 specialized upstream industries affect downstream survival rates 2 the prevalence of different governance forms among upstream and downstream organizations moderates this relationship and 3 different forms of governance exert differential competitive pressures on focal organizations we find evidence supporting our hypotheses in an empirical examination of the downstream laser printer industry and upstream laser engine industry this paper was accepted by jesper sorensen organizations

the effects of school spending on educational and economic outcomes evidence from school finance reforms since the coleman report many have questioned whether public school spending affects student outcomes the school finance reforms that began in the early 1970s and accelerated in the 1980s caused dramatic changes to the structure of k 12 education spending in the united states to study the effect of these school finance reform induced changes in public school spending on long run adult outcomes we link school spending and school finance reform data to detailed nationally representative data on children born between 1955 and 1985 and followed through 2011 we use the timing of the passage of court mandated reforms and their associated type of funding formula change as exogenous shifters of school spending and we compare the adult outcomes of cohorts that were differentially exposed to school finance reforms depending on place and year of birth event study and instrumental variable models reveal that a 10 increase in per pupil spending each year for all 12 years of public school leads to 0 31 more completed years of education about 7 higher wages and a 3 2 percentage point reduction in the annual incidence of adult poverty effects are much more pronounced for children from low income families exogenous spending increases were associated with notable improvements in measured school inputs including reductions in student to teacher ratios increases in teacher salaries and longer school years jel codes j10 i20 h7

analysis of the effectiveness of the first european pollutant emission register eper abstract the aim of this paper is to examine the effectiveness of the first european pollution emissions register eper a regulatory instrument based on the publication of the environmental performance of firms exceeding specified pollution limits the multivariate regression model mvrm is applied to capture the disciplinary effect of the eper so we first perform an analysis to determine whether the publication of the eper has a negative effect on the market value of the listed firms secondly we consider the possibility of the publication of the eper affecting the market value of firms which could be included in the eper but are not because their emissions do not exceed the specified pollution limits finally we prepare an index to compare the environmental results of the firms and analyse whether the consequences of publishing the eper are worse for firms with high relative pollution records

the relationship between education and adult mortality in the united states prior research has uncovered a large and positive correlation between education and health this paper examines whether education has a causal impact on health i follow synthetic cohorts using successive u s censuses to estimate the impact of educational attainment on mortality rates i use compulsory education laws from 1915 to 1939 as instruments for education the results suggest that education has a causal impact on mortality and that this effect is perhaps larger than has been previously estimated in the literature copyright 2005 wiley blackwell

sustainable competitive advantage combining institutional and resource based views this article suggests that the context and process of resource selection have an important influence on firm heterogeneity and sustainable competitive advantage it is argued that a firm s sustainable advantage depends on its ability to manage the institutional context of its resource decisions a firm s institutional context includes its internal culture as well as broader influences from the state society and interfirm relations that define socially acceptable economic behavior a process model of firm heterogeneity is proposed that combines the insights of a resource based view with the institutional perspective from organization theory normative rationality institutional isolating mechanisms and institutional sources of firm homogeneity are proposed as determinants of rent potential that complement and extend resource based explanations of firm variation and sustainable competitive advantage the article suggests that both resource capital and institutional capital are indispensable to sustainable competitive advantage 1997 john wiley sons ltd

the big bug the legitimation of the edible insect sector in the netherlands abstract this study analyzes the legitimation process of an emerging novel food sector in the european union eu current eu policies are cautious with regard to new food sources and new food technology and we aim to determine how the sector is addressing both this caution as well as a general public that may be skeptical of its products by utilizing a legitimacy strategy framework and conducting 19 semi structured interviews with actors and experts in the dutch edible insect sector we assess the sector s progress and limitations with regard to its legitimacy journey the findings show that sector focus has thus far been on organization intraindustry and interindustry legitimacy strategies and that additional emphasis on institutional strategies will be imperative to securing more accommodating legislation in addition the lack of a common vision a strategic communication plan and interfirm linkages may also be hindering sector legitimation the framework and conclusions presented here may prove useful to other sectors introducing novel foods

long term neighborhood effects on low income families evidence from moving to opportunity abstract we examine long term neighborhood effects on low income families using data from the moving to opportunity mto randomized housing mobility experiment this experiment offered to some public housing families but not to others the chance to move to less disadvantaged neighborhoods we show that ten to 15 years after baseline mto i improves adult physical and mental health ii has no detectable effect on economic outcomes or youth schooling or physical health and iii has mixed results by gender on other youth outcomes with girls doing better on some measures and boys doing worse despite the somewhat mixed pattern of impacts on traditional behavioral outcomes mto moves substantially improve adult subjective well being

organisational ecology in the danish restaurant sector abstract the article demonstrates the high rates of organisational turmoil in the restaurant sector the intensity of natural selection depends mainly on the age and size of the enterprise affiliation with other enterprises increases the chances of survival but only if there is a substantial number of units co operating in a group surprisingly the level of staff competence and managerial capacity measured in quantitative terms cannot explain the level of success or failure in the restaurant business to any significant degree organisational ecology which constitutes the theoretical and methodological base of this article is a promising research approach to tourism issues the article which focuses on explanations for the occurrence of life events in the restaurant sector calls for more careful policy considerations than are often the case in particular human resource and labour market related actions should be critically reassessed

teachers pay for performance in the long run the dynamic pattern of treatment effects on students educational and labour market outcomes in adulthood this paper examines the dynamic effects of a teachers pay for performance experiment on long term outcomes at adulthood the program led to a gradual increase in university education of the treated high school students reaching an increase of 0 25 years of schooling by age 28 30 the effects on employment and earnings were initially negative coinciding with a higher rate of enrollment in university but became positive and significant with time these gains are largely mediated by the positive effect of the program on several high school outcomes including quantitative and qualitative gains in the high stakes matriculation exams

ties that bind how business connections affect mutual fund activism we investigate whether business ties with portfolio firms influence mutual funds proxy voting using a comprehensive data set spanning 2003 to 2011 in contrast to prior literature we find that business ties significantly influence promanagement voting at the level of individual pairs of fund families and firms after controlling for institutional shareholder services iss recommendations and holdings the association is significant only for shareholder sponsored proposals and stronger for those that pass or fail by relatively narrow margins our findings are consistent with a demand driven model of biased voting in which company managers use existing business ties with funds to influence how they vote abstract from author

density dependence in the evolution of populations of newspaper organizations a model of density dependence is proposed to explain regularities in the growth and decline of organizational populations density the number of organizations is assumed to be a function of the social processes of legitimation and competition at low density the model predicts that the legitimation process will dominate and will lead to high organizational founding rates and low organizational mortality rates at high levels of density competition will dominate and consequently founding rates will decline and mortality rates will rise the model is tested with hazard function models using data from nine newspaper populations spanning the 19th and 20th centuries and covering over 5200 newspapers analysis offounding rates provides strong empirical support for the model analysis of mortality rates reveals that the model holds for large populations

business ties and proxy voting by mutual funds abstract the magnitude of mutual funds business ties with their portfolio firms is documented and is linked to funds proxy votes at specific firms and to overall voting practices aggregate votes at the fund family level indicate a positive relation between business ties and the propensity to vote with management votes at specific firms however reveal that funds are no more likely to vote with management of client firms than of non clients because the votes took place when funds knew their votes would be publicly scrutinized fund families with a larger client base may have adopted voting policies that led to less frequent opposition to management at all firms

to be different or to be the same it s a question and theory of strategic balance this paper addresses the performance consequences of firm level strategic similarity past research observed that firms face pressures to be different and to be the same by differentiating firms reduce competition by conforming firms demonstrate their legitimacy both reduced competition and legitimacy improve performance this paper begins building a theory of strategic balance by synthesizing the differentiation and conformity perspectives the theory directs attention to intermediate levels of strategic similarity where firms balance the pressures of competition and legitimation empirical support for the theory is found in a longitudinal study of commercial banks several suggestions for developing a theory of strategic balance conclude the paper the theory s major implication is that firms should be as different as legitimately possible copyright 1999 john wiley sons ltd

incentives work getting teachers to come to school we use a randomized experiment and a structural model to test whether monitoring and financial incentives can reduce teacher absence and increase learning in india in treatment schools teachers attendance was monitored daily using cameras and their salaries were made a nonlinear function of attendance teacher absenteeism in the treatment group fell by 21 percentage points relative to the control group and the children s test scores increased by 0 17 standard deviations we estimate a structural dynamic labor supply model and find that teachers respond strongly to financial incentives our model is used to compute cost minimizing compensation policies jel i21 j31 j45 o15

crowding out the role of state companies and the dynamics of industrial competitiveness in india this article examines growth patterns of government companies in india whether their presence has crowded out private entrepreneurial activity and whether there has been a decline in the competitiveness of india s industry measured as relative productive efficiency for a 45 year period from 1957 1958 to 2001 2002 there was a significant growth in the number of government companies in india that effectively crowded out the entry and growth of private enterprise this took place from the mid to late 1950s to the late 1980s and early 1990s correspondingly the amount of private equity capital invested in firms declined until the late 1980s and early 1990s when there was an upsurge of private investment activity another feature was that a small number of government companies absorbed most of the corporate sector equity investment in india the growth in the share of government companies in india that crowded out the entry and growth of private enterprises has had a significantly negative effect on india s industrial competitiveness after the introduction of reforms in 1991 there has been a significant crowding in by private enterprises displacing the government companies from their key position as holders of a very large portion of equity capital and also reversing the trend in the decline of competitiveness of indian industry as a whole copyright 2009 oxford university press

does compulsory school attendance affect schooling and earnings we establish that season of birth is related to educational attainment because of school start age policy and compulsory school attendance laws individuals born in the beginning of the year start school at an older age and can therefore drop out after completing less schooling than individuals born near the end of the year roughly 25 percent of potential dropouts remain in school because of compulsory schooling laws we estimate the impact of compulsory schooling on earnings by using quarter of birth as an instrument for education the instrumental variables estimate of the return to education is close to the ordinary least squares estimate suggesting that there is little bias in conventional estimates every developed country in the world has a compulsory schooling requirement yet little is known about the effect these laws have on educational attainment and earnings 1 this paper exploits an unusual natural experiment to estimate the impact of compulsory schooling laws in the united states the experiment stems from the fact that children born in different months of the year start school at different ages while compulsory schooling laws generally require students to remain in school until their sixteenth or seventeenth birthday in effect the interaction of school entry requirements and compulsory schooling laws compel students born

mimetic and experiential effects in international marketing alliance formations of us pharmaceuticals firms an event history analysis alliances are recognized as an indispensable tool for managers operating in a global business environment and as a fundamental stage of the internationalization process of the firm drawing on a co evolutionary framework this article investigates the mimetic and experiential effects in international alliance formation we focus on a critical unresolved issue in the literature what is the role of mimetic behavior and previous alliance experience in mitigating the uncertainty associated with engaging in cross border operations an event history analysis of 792 international marketing alliance formations initiated by 317 firms in the us pharmaceutical industry is employed to test the hypotheses the findings of two different hazard rate models reveal significant complex effects of density and cross border alliance experience on the propensity to engage in new international marketing alliances

does school quality matter returns to education and the characteristics of public schools in the united states this paper estimates the effects of school quality measured by the pupil teacher ratio average term length and relative teacher pay on the rate of return to education for men born between 1920 and 1949 using earnings data from the 1980 census we find that men who were educated in states with higher quality schools have a higher return to additional years of schooling rates of return are also higher for individuals from states with better educated teachers and with a higher fraction of female teachers holding constant school quality measures however we find no evidence that parental income or education affects average state level rates of return

performance pay and teachers effort productivity and grading ethics this paper presents evidence about the effect of individual monetary incentives on english and math teachers in israel teachers were rewarded with cash bonuses for improving their students performance in high school matriculation exams the main identification strategy is based on measurement error in the assignment to treatment variable that produced a randomized treatment sample the incentives led to significant improvements in test taking rates conditional pass rates and mean test scores improvements were mediated through changes in teaching methods enhanced after school teaching and increased responsiveness to students needs no evidence was found of manipulation of test scores by teachers

the effects of exposure to better neighborhoods on children new evidence from the moving to opportunity experiment the moving to opportunity mto experiment offered randomly selected families housing vouchers to move from high poverty housing projects to lower poverty neighborhoods we analyze mto s impacts on children s long term outcomes using tax data we find that moving to a lower poverty neighborhood when young before age 13 increases college attendance and earnings and reduces single parenthood rates moving as an adolescent has slightly negative impacts perhaps because of disruption effects the decline in the gains from moving with the age when children move suggests that the duration of exposure to better environments during childhood is an important determinant of children s long term outcomes jel i31 i38 j13 r23 r38

behind the scenes the corporate governance preferences of institutional investors we survey institutional investors to better understand their role in the corporate governance of firms consistent with a number of theories we document widespread behind the scenes intervention as well as governance motivated exit these governance mechanisms are viewed as complementary devices with intervention typically occurring prior to a potential exit we further find that long term investors and investors that are less concerned about stock liquidity intervene more intensively finally we find that most investors use proxy advisors and believe that the information provided by such advisors improves their own voting decisions

how does your kindergarten classroom affect your earnings evidence from project star in project star 11 571 students in tennessee and their teachers were randomly assigned to classrooms within their schools from kindergarten to third grade this article evaluates the long term impacts of star by linking the experimental data to administrative records we first demonstrate that kindergarten test scores are highly correlated with outcomes such as earnings at age 27 college attendance home ownership and retirement savings we then document four sets of experimental impacts first students in small classes are significantly more likely to attend college and exhibit improvements on other outcomes class size does not have a significant effect on earnings at age 27 but this effect is imprecisely estimated second students who had a more experienced teacher in kindergarten have higher earnings third an analysis of variance reveals significant classroom effects on earnings students who were randomly assigned to higher quality classrooms in grades k 3 as measured by classmates end of class test scores have higher earnings college attendance rates and other outcomes finally the effects of class quality fade out on test scores in later grades but gains in noncognitive measures persist

density dependence versus population dynamics an ecological study of failings in the california wine industry in this ecological study we show that the particular curvilinear formulation of the relationship between density and the failing rate of organizations proposed by hannan and freeman does not hold for the california wine industry between 1940 and 1985 we demonstrate instead that an alternative model focusing on prior foundings and prior failings gives a superior account of the failing rate in this population we argue that hannan and freeman s density dependent model of organizational mortality systematically overstates the negative effects of illegitimacy on business organizations we argue further that their model underestimates business organizations ability to avoid elimination by migrating to neighboring niches and by enlarging their initial niche

the dynamics of rapid industrial growth evidence from sweden s information technology industry 1990 2004 sweden s information technology it industry expanded through an inflow of new entrants during the 1990s its evolution was analyzed using ecological models of organizational founding and disbanding controlling for the effects of economic conditions this study analyzed the effects of density dependence age imprinting rate dependence and the origin of new entrants on the industry the results indicate that the inflow was comprised of start ups that proved to be relatively short lived in contrast new entrants that originated as part of incumbent firms that were diversifying in it stabilized the industry by depressing its disbanding rate and facilitating the entry of new firms in explaining the dynamics of the industry the analysis supports the established models of density dependence age dependence imprinting and organizational origin copyright 2009 the author 2009 published by oxford university press on behalf of associazione icc all rights reserved oxford university press

interdependent behavior in foreign direct investment the multi level effects of prior entry and prior exit on foreign market entry this paper examines the interdependent foreign market entry decisions of multinational corporations mncs based on the argument that legitimacy and competition are two important forces in foreign market entry decisions we hypothesize that an mnc s market entry decisions are influenced by its own prior entry and prior exit decisions and those of other mncs we examine this general proposition at four levels of analysis the host country global industry an industry that spans host countries local industry an industry that is separately defined within each host country and parent firm level our analysis of a panel data of over 4000 market entry decisions that were made by japanese mncs shows that an mnc s market entry decision has a stronger inverted u shaped relationship with the prior entry and exit decisions of other mncs at the local industry level than the prior entry and exit decisions of other mncs at the host country and global industry levels we also find that both the prior entry and prior exit decisions of an mnc have a marginal influence on its own subsequent market entry decisions at the parent firm level

technological platforms and diversification as the invention of fundamental new sciences spawns subsequent research discovery and commercialization core technologies branch into new applications and markets some of them evolve over time into many derived technologies whereas others are essentially dead ends the pattern of evolution and branching is called a technological trajectory an intriguing question is whether some firms can ride the trajectory by developing proprietary experience in a platform technology because the knowledge is proprietary firms that originate in industrial fields based on a platform technology acquire the technological skills to diversify and to mimic the branching of the underlying technological trajectory the ability to compete in hypercompetitive markets depends on the acquisition of know how that is applicable to a wide set of market opportunities such capabilities serve as platforms into quickly evolving markets to respond rapidly to market changes a firm must have already acquired fundamental compet

the structure of competition how competition between one s rivals influences imitative market entry this paper investigates how the pattern of encounters between a firm s competitors affects the firm s inclination to follow its competitors into a new market we theorize that direct encounters between a firm s rivals lead to a herding effect making imitative market entry more likely past mutual forbearance between a firm s competitors resulting from asymmetric multimarket competition further strengthens this herding effect by enhancing the firm s expectations of market attractiveness in contrast aggressive past rivalry between the competitors resulting from symmetric multimarket contact dampens these expectations producing a competition effect that makes herding less probable we test our idea in two distinct contexts the chinese pharmaceutical industry and the taiwanese computer hardware industry and find consistent support in both settings we discuss how our analysis of what we call the structure of competition can be extended to research on other forms of firm behavior

getting to global an evolutionary perspective of brand expansion in international markets the globalization of brands is an evolutionary process that is determined by environmental and firm level factors including a brand s position in the firm s global brand architecture a framework is developed incorporating aspects of environmental uncertainty mimetic behavior and experiential learning as they relate to the globalization of brands global brand architecture is introduced as an important strategic consideration of a brand s position and stage of internationalization the hypotheses are tested within the context of the global automotive industry employing an event history analysis with time varying covariates the results reveal complex effects with respect to the role of market attractiveness experiential learning and mimetic behavior in globalization patterns overall this study suggests that firms can accelerate the process of creating global brands if they enter the three major continents in the early stages of international expansion

the decline of social entrenchment social network cohesion and board responsiveness to shareholder activism shareholder activism through corporate governance proposals is a prominent avenue for investors to voice their concerns in corporate governance matters however shareholder proposals have an uneven effect on corporate governance this paper contributes to research on shareholder activism by joining social movement approaches to activism with network theoretic approaches to corporate governance the paper examines how firms position within cohesive sections of the board interlock network termed social entrenchment predicts 1 the likelihood of being targeted by activist investors and 2 firms responsiveness to proposal demands first a firm s position in the board network serves as a salient network prism attracting activists attention this is especially true for activist investors who lack other backchannel avenues for engagement or seek to use public reputational penalties as part of their activism strategy second the board network traditionally served as an important collective infrastruc

analyzing unexpected density dependence effects on organizational births in new york s life insurance industry 1842 1904 organizational ecologists argue that numbers of firms density dependence significantly affect industrial development rising numbers of firms are thought to legitimize a young industry leading persons to launch new firms in the industry but in a more crowded older industry increasing numbers of companies are expected to intensify competition producing a decline in organizational births since this argument dominates ecological theory results that challenge it must be explained i identify six reasons for such results only a few of these explanations have been evaluated empirically and the ideas rarely have been assessed with respect to organizational births therefore i address these explanations in order to resolve unexpected density dependence effects on foundings in new york s life insurance industry from 1842 to 1904 measuring numbers of life insurance operators at both the state new york and national u s levels of analysis resolves the unexpected density dynamics in this study and produces a coherent pattern of density findings further numbers of mutual savings banks and numbers of small life insurers in new york created competitive pressures in the life insurance business leading persons to abandon carrier entrepreneurship entrepreneurship also suffered when the life insurance industry was dominated by a few large sellers more generally the evidence shows that new york was divided into two insurance submarkets and that carrier organizers reacted to legitimation and competition trends in the submarket occupied by domestic insurers i conclude that once we consider the reasons for unexpected density dynamics the core model of density dependence offers a cogent explanation for industrial evolution

does head start improve children s life chances evidence from a regression discontinuity design this paper exploits a new source of variation in head start funding to identify the program s effects on health and schooling in 1965 the office of economic opportunity oeo provided technical assistance to the 300 poorest counties to develop head start proposals the result was a large and lasting discontinuity in head start funding rates at the oeo cutoff for grant writing assistance we find evidence of a large drop at the oeo cutoff in mortality rates for children from causes that could be affected by head start as well as suggestive evidence for a positive effect on educational attainment i introduction head start was established in 1965 as part of the war on poverty to provide preschool health and other social services to poor children age three to five and their families and currently serves over 900 000 children each year at a cost of around 7 billion hhs 2006 this paper provides new evidence on the effects of the head start program on schooling and health by drawing on a new source of variation in program funding spe

the impact of economic conditions on participation in disability programs evidence from the coal boom and bust abstract we examine the impact of the coal boom of the 1970 s and the coal bust of the 1980 s on disability program participation these shocks provide clear evidence that as the value of labor market participation increases disability program participation falls for the disability insurance program the elasticity of payments with respect to local earnings is between 0 3 and 0 4 and for supplemental security income the elasticity is between 0 4 and 0 7 consistent with a model where qualifying for disability programs is costly the relationship between economic conditions and program participation is much stronger for permanent than for transitory economic shocks

industry competition and firm human capital this paper argues that objective and subjective human capital may have substantial impact upon organizational performance in a competitive context objective human capital pertains to such features as education and experience whereas subjective human capital relates to personality characteristics the argument is illustrated by presenting the results of two empirical studies 1 a cross section 1990 1991 analysis of about 50 incumbents in the flemish furniture industry concentrating on the impact of subjective human capital particularly the chief executive officer s ceo s locus of control personality on financial performance and 2 a longitudinal 1970 1992 analysis of a cohort of 100 entrants into the dutch audit industry focusing on the influence of objective human capital particularly education and experience on exit by merger and acquisition m a or diaspora both studies support the claim that objective and subjective human capital matters for example flemish furniture firms headed by a ceo with an internal locus of control trait reach higher levels of financial performance and dutch audit firms with a high proportion of personnel with business experience are more likely to exit the industry over the years as a result of diaspora finally the data of the flemish furniture and dutch audit industries are re analyzed so as to compare the impact of human capital variables on small firm performance in both industries this re analysis reveals that in both industries the impact of human capital variables is more pronounced in large firms compared to small businesses

decomposing uncertainty and its effects on imitation in firm exit decisions this study examines the effects of different uncertainty types on interorganizational imitation in firm exit decisions we draw on herding models to conceptualize exit decisions as being based on a firm s private information which the firm updates with information inferred from observing the actions of others we posit that different types of uncertainty differentially affect this observational learning process in particular we propose that certain uncertainty types attenuate rather than foster observational learning and subsequent imitation we test this theory using a 29 year panel data set on the exit of private venture capital firms our results indicate that observational learning does influence imitation in firm exit decisions and they also suggest that a common belief that uncertainty enhances imitation does not apply to all types of uncertainty specifically we find that uncertainty fosters imitation only when it is idiosyncratic to the firm uncertainties that are common to all firms in contrast actually reduce reliance on observational learning by decomposing uncertainty into different types and explicating their effects on imitation we demonstrate that this relationship is more nuanced than previously assumed and in addition highlight the role of deliberate information processing in imitation

dynamic capabilities and new product development in high technology ventures an empirical analysis of new biotechnology firms abstract in industries populated by entrepreneurial high technology firms the rapid development of new products is viewed as a key determinant of success developing a portfolio of new products is necessary to gain early cash flows external visibility and legitimacy early market share and increase the likelihood of survival schoonhoven eisenhardt and lymman 1990 in addition recent research has shown that new product development improves a firm s ability to raise money through an initial public offering deeds decarolis and coombs 1997 this paper develops a model of new product development which is tested on a sample of 94 pharmaceutical biotechnology companies we hypothesize that new product development capabilities are a function of a firm s scientific technological and managerial skills to test this relationship we develop several firm specific measures in an attempt to triangulate in on the core construct of firm specific new product development capabilities some important implications for entrepreneurs managers of high technology firms flow from our results first entrepreneur managers need to view the choice of geographic location as an important strategic decision which will impact their firm s access to the skilled technical personnel and the streams of knowledge our results indicate that a choice location has a significant concentration of similar firms but the level has not yet reached a point where competition for resources in the local environment offsets any advantages of the location in the case of biotechnology this would seem to indicate that the prime locations would be expanding areas such as san diego seattle and philadelphia rather then the established locations of silicon valley and boston second as scientific knowledge plays an ever more important role in a firm s success the quality of the firm s scientific team is a critical ingredient in a firm s new product development capability but how do you evaluate the quality of scientific personnel our results indicate that there is a strong positive relationship between the impact as measured by citations of a team s prior research in the academic community and the productivity of that team in a commercial research laboratory therefore the judgement of a scientific field captured by citations or perhaps expert judgement should prove to be a useful tool when evaluating personnel for a firm s research team third the results from our measures of ceo experience and the percentage of the top management team with a ph d are interesting as expected the prior experience of ceo in managing a commercial research facility enhances a firm s new product development capabilities however results for our top management team variable appears to indicate that the over reliance on technical personnel in the management of the organization detracts from the product development process taken together these results seem to imply that it is important that the leadership of the organization have knowledge of and experience in managing the new product development process but that diverting the firm s scientific personnel s energies away from the laboratory and into the management of the organization maybe counter productive therefore what a high technology venture appears to need is leadership that understands and has experience in the new product development process but which is separate and distinct from the scientific team this type of leadership keeps the scientific team focused on research and development and out of the boardroom

the impact of social structure on economic outcomes s ocial structure especially in the form of social networks affects economic outcomes for three main reasons first social networks affect the flow and the quality of information much information is subtle nuanced and difficult to verify so actors do not believe impersonal sources and instead rely on people they know second social networks are an important source of reward and punishment since these are often magnified in their impact when coming from others personally known third trust by which i mean the confidence that others will do the right thing despite a clear balance of incentives to the contrary emerges if it does in the context of a social network economists have recently devoted considerable attention to the impact of social structure and networks on the economy for example see the economists chapters in rauch and casella 2001 and the illuminating review essay of this volume by zuckerman 2003 as well as dutta and jackson 2003 and calvoarmengol 2004 however i focus here on sociologists contributions sociologists have developed core principles about the interactions of social structure information ability to punish or reward and trust that frequently recur in their analyses of political economic and other institutions i begin by reviewing some of these principles building on these i then discuss how social structures and social networks can affect economic outcomes like hiring price productivity and innovation

networks as the pipes and prisms of the market1 this article draws an analytical distinction between two types of market uncertainty egocentric which refers to a focal actor s uncertainty regarding the best way to convert a set of inputs to an output desired by a potential exchange partner and altercentric which denotes the uncertainty confronted by a focal actor s exchange partners regarding the quality of the output that the focal actor brings to the market given this distinction the article considers how the value of structural holes and market status vary with these two types of uncertainty the article proposes that the value of structural holes increases with egocentric uncertainty but not with altercentric uncertainty in contrast the value of status increases with altercentric uncertainty but declines with egocentric uncertainty thus actors with networks rich in structural holes should sort into markets or market segments that are high in egocentric uncertainty high status actors should sort into markets that are low in egocentric

moderating effects of investor experience on the signaling value of private equity placements abstract we contend that young start up firms requiring external capital are able to differentiate themselves from competitors through their choices of investors and financing mechanisms private placements of equity convey efficient signals to markets for several reasons they are short term irreversible occur after a more rigorous analysis than public offerings provide contain governance mechanisms and are generally observable by outsiders the disclosure that investors possess a superior reputation for evaluative ability conveys an additional endorsing signal of the firm s prospects this proves especially valuable for younger firms less capitalized firms and firms that have more recently received private equity from an experienced investor using an event history analysis on a sample of 329 publicly held biotechnology firms we find firms that are perceived to be more uncertain and that disclose the presence of more prominent investors are better able to attract subsequent financing

how responsive is investment in schooling to changes in redistributive policies and in returns this paper uses an unusual pay reform to test the responsiveness of investment in schooling to changes in redistribution schemes that increase the rate of return to education we exploit an episode where different israeli kibbutzim shifted from equal sharing to productivity based wages in different years and find that students in kibbutzim that reformed earlier invested more in high school education and in the long run also in post secondary schooling we further show that the effect is mainly driven by students in kibbutzim that reformed to a larger degree our findings support the prediction that education is highly responsive to changes in the redistribution policy
