learning from own and others previous experience the contribution of the venture capital firm to the likelihood of a portfolio company s trade sale the objective of this paper is to examine to what extent different venture capital firms contribute to the likelihood that the portfolio company in which they invested will realize a trade sale we use arguments from learning theory to hypothesize the relationship between vicarious experiential and congenital learning of the venture capital vc firm and the trade sale hazard of its portfolio companies based on our analysis of 206 vc backed uk start ups we find that both trade sale experience of the vc and learning from syndicate partners with trade sale experience significantly increase the trade sale hazard the routines and procedures learned from experienced syndicate partners complement experience accumulated through trial and error congenital trade sale experience of the investment managers on the contrary has no significant influence on the acquisition hazard

angel investors around the world we document that the choice between disintermediated individual angel investments and intermediated private equity and venture capital investments depends on legal economic and cultural differences we find evidence of this using pitchbook s comprehensive data on more than 5000 angel and 80 000 private equity and venture capital investments in 96 countries from 1977 to 2012 the data further indicate that investee firms funded by angels are less likely to successfully exit through either an ipo or an acquisition these findings are robust to propensity score matching methods as well as to clustering standard errors and excluding u s observations among other approaches

the empirical content of the roy model this paper clarifies and extends the classical roy model of self selection and earnings inequality the original roy model based on the assumption that log skills are normally distributed is shown to imply that pursuit of comparative advantage in a free market reduces earnings inequality compared to the earnings distribution that would result if workers were randomly assigned to sectors aggregate log earnings are right skewed even if one sectoral distribution is left skewed most major implications of the log normal roy model survive if differences in skills are log concave however few implications of the model survive if skills are generated from more general distributions we consider the identifiability of the roy model from data on earnings distributions the normal theory version is identifiable without regressors or exclusion restrictions sectoral distributions can be identified knowing only the aggregate earnings distribution for general skill distributions the model is not identified and has no empirical content with sufficient price variation the model can be identified from multimarket data cross sectional variation in regressors can substitute for price variation in restoring empirical content to the roy model

occupational mobility occupation distance and specific human capital abstract distance and direction measures are constructed and used to contrast occupational mobility following involuntary job displacement and total occupational mobility displacement involves specific capital loss some voluntary occupational mobility for example promotions reflects augmented skills rather than specific human capital loss wage losses following displacement are strongly related to distance and direction this is reflected in a downward shift in the skill portfolio by contrast the skill portfolio change in total occupational mobility shows a neutral or modest upward pattern suggesting limited or no specific human capital loss from voluntary occupational mobility the mean distance in occupational mobility following displacement declined significantly in the 1980s and 1990s suggesting the labor market was more efficiently reemploying workers following displacement lowering displacement costs in that period

the board and strategy venture capital and high technology abstract in the area of strategy formulation the part played by the board of directors in high technology firms operating with funds provided by venture capital organizations has not been investigated before this exploratory study although based on a limited sample looks at some of the fundamental issues and contrasts the involvement of the board in firms of this kind with very limited involvement of the board in small conventional firms and in large publicly held corporations the relative power of management and the board of directors is of great importance in contrast with the small conventional firm and the large corporation in both of which the chief executive officer is usually in firm control of the board and generally does not look to the board for active involvement in strategy formulation the high technology firms funded by venture capital organizations are characterized by a board of directors that has high power relative to management this power can be understood not only in terms of the power of the purse high concentration of the ownership in hands external to management but also in terms of the expertise of the venture capitalists and their access to important networks the business plan which is a key element in obtaining initial funding is in effect a statement of strategy that is carefully scrutinized by the venture capitalists some of whom will assume positions on the board of directors the board is similarly involved in the revisions of business plans in conjunction with later rounds of funding the study found that the board is typically small with outsiders rather than management in control further at least some of the outside members were found to have a high degree of expertise and a close working relationship with management board meetings are frequent and deal actively with key issues and with the review of how the strategy is working and what changes in strategy may be required reviews of the business plan when a new round of funding is required or when major new product or marketing decisions are needed are examples of likely occasions for involvement of the board in strategy revisions further research should center on identifying the conditions under which board involvement can play a constructive role in the strategy process of these high technology companies some pertinent variables are suggested the next step in research should be more structured and quantitative and should use a geographically dispersed sample but field interviews will be of continuing value as a complement for firms funded by venture capital organizations the board of directors is a significant interface between the venture capitalists and the internal management group the working relationship between inside and outside directors in this arena in strategy formulation and in other major business decisions is a matter of considerable practical importance

new venture teams assessment of learning assistance from venture capital firms abstract prior research examining whether venture capital firms vcs add value to the ventures in their portfolios by advising their new venture teams nvts has led to inconclusive results whereas most prior studies have assumed that nvts value vc assistance this study tests for the possibility that they differentially value two different types of vc assistance business management and operational we collected data by surveying 837 firms identified in the venture capital journal that had received financing from venture capital firms only firms that received first round financing were included in our analysis which reduced our sample size to 205 firms our central finding is that systematic differences exist among nvts in their evaluation of learning assistance from vcs even though vcs can chose their own level of involvement with an nvt successfully improving venture performance through nonfinancial assistance at least partially depends upon the extent to which the nvt values vc input our results indicate that nvts with more industry experience and longer team tenure in the current venture are negatively related to both business management advice and operational assistance offered by their vcs however when an nvt has previously worked together and when its primary experience is from another industry it tends to welcome business management advice from its vc one interpretation of this finding is that an advanced level of operational specialization already exists in such a team which reinforces established operating patterns changing established operating patterns could make it more costly to adopt vc input on operational issues however business management advice may be more welcome because the nvt is still learning how to compete in a new industry these findings add to the growing literature that suggests that vcs play a particularly important role in entrepreneurial ventures when they pursue the development of new technologies ehrlich et al 1994 sapienza 1992 however business management advice is not highly valued by nvts that pursue more technical innovations these findings in combination with those of sapienza and amason 1993 suggest that conflict in the vc nvt relationship may be the greatest when the parties attempt to resolve critical differences which ironically appear to be the ones where the nvt could derive the greatest benefit from listening to its vc finally current firm performance is not related to the nvt s evaluation of vc assistance although cross sectional measures of performance have obvious limitations particularly with new ventures these results indicate that the nvt evaluation of vc assistance is not driven by short term performance past research has shown that vcs vary widely in their preferred level of involvement with the managers of firms in their portfolio some vcs prefer a laissez faire approach whereas others think that they must be more involved if they are to ultimately receive high rewards the central finding from this study is that significant differences exist among nvts in their evaluation of business management and operational assistance for vcs that are more involved these findings suggest that the optimal level of involvement is also partially contingent upon the nvts openness to learning ignoring the contingent nature of the vc nvt relationship vcs could reduce their influence as a tool to improve firm performance and to ensure the ultimate survival of the venture

allocation of attention within venture capital firms in this article we use a simple queuing network to model the process through which entrepreneurs receive venture capital funding our model focuses in particular on the allocation of venture capitalists attention between pre and post investment activities and on the degree of selectivity in deciding which ventures to fund based upon this model we develop expressions for the financial performance of the venture capital process both overall and also from the perspectives of the entrepreneurs investors managers and venture capitalists involved for these financial measures we derive the optimal allocation of attention between pre and post investment activities and the optimal proportion of venture proposals to accept further analysis shows how these different financial measures and optimal values respond to changes in the business climate more interestingly our analysis also shows where and to what extent the different parties could be expected to agree or disagree on how best to manage the process

reassessing the relationships between private equity investors and their portfolio companies the scope and purpose of this special issue is to reassess the relationships between private equity pe investors and their portfolio companies in the light of the need for venture capital private equity vc pe firms to adapt their strategies for value creation in the light of the recent financial crisis we particularly focus upon vc pe characteristics that differently contribute to portfolio firm performance the papers presented in this special issue capture this aim in various ways reflecting the heterogeneity of vc pe investors and the firms in which they invest we begin this introductory paper by providing a brief overview of each paper s contribution we articulate themes for an agenda for future research relating to the heterogeneity of investor types and the contexts in which they invest

cap and trade and financial constraints is investment independent of permit holdings we study a new channel by which permit holdings in a cap and trade system can affect investment behavior in the presence of financial constraints permit holdings can matter through their effect on the firm s internally available resources and indirectly affect investment to test this relationship we exploit the cross sectional and temporal variation in permit holdings and the temporal variation in the price of permits in the us hbox so 2 program we find that capital expenditures are positively related to the market value of the permit holdings this relationship is stronger for smaller firms and is robust to alternative explanations based on regulatory differences

data improvement and labor economics the expansion of available data for research has transformed empirical labor economics over the past generation this paper briefly highlights some of the changes and describes a few examples of papers that illustrate the advances it also documents the changing ways data have been used in the journal of labor economics over the past 30 years including a trend toward a higher fraction of papers using any data and among those papers using any data a higher fraction using nonpublic data a higher fraction using international data and more frequent use of multiple data sources finally this paper describes work that came out of the recent princeton data improvement initiative a program that considers and furthers improved data collection

accounting conservatism and firm investment efficiency abstract we argue that conservatism improves investment efficiency in particular we predict that it resolves debt equity conflicts facilitating a firm s access to debt financing and limiting underinvestment this permits the financing of prudent investments that otherwise might not be pursued our empirical results confirm these predictions we find that more conservative firms invest more and issue more debt in settings prone to underinvestment and that these effects are more pronounced in firms characterized by greater information asymmetries we also find that conservatism is associated with reduced overinvestment even for opaque investments such as research and development

comparative advantage learning and sectoral wage determination we develop a model in which a worker s skills determine the worker s current wage and sector the market and the worker are initially uncertain about some of the worker s skills endogenous wage changes and sector mobility occur as labor market participants learn about these unobserved skills we show how the model can be estimated using nonlinear instrumental variables techniques we apply our methodology to study wages and allocation of workers across occupations and industries using individual level panel data from the national longitudinal survey of youth we find that high wage sectors employ high skill workers and offer high returns to workers skills

underpaid or overpaid wage analysis for nurses using job and worker attributes the nursing labor market presents an apparent puzzle hospitals report chronic shortages yet standard wage analysis shows that nursing wages have increased over time and greatly exceed those received by other college educated women this paper addresses this puzzle data from the current population survey cps are matched with detailed job content descriptors from the occupational information network o net nursing jobs require higher levels of skills and more difficult working conditions than do jobs for other college educated workers a standard cps only wage regression shows a registered nurse rn wage advantage of 22 log points compared to a pooled male female group of college educated workers control for o net job attributes reduces the rn gap to 08 while an arguably preferable nonparametric estimator produces a wage gap estimate close to zero we conclude that nurses receive compensation close to long run opportunity costs narrowing if not resolving the rn wage shortage puzzle

firm specific human capital a skill weights approach the theory of human capital is agnostic on what constitutes firm specific skills the theory specifies that specific skills contribute to productivity only at the current firm a broader approach lets all skills be general but firms use them with different weights attached for example computer programming economics and accounting are general skills but there may be only one firm that wants workers trained in all three one implication is that wage profiles and the split of human capital costs depend on thickness of the market another is that firms pay for what appears to be general training

the impact of labor unions on investment cash flow sensitivity abstract this paper empirically examines how labor unions affect investment cash flow sensitivity using samples from the us covering the period of 1984 2009 we find a significant positive union effect using a q model of investment the capital expenditures of firms are 1 71 times more sensitive to internal cash flows when unionization rates increase one standard deviation from the mean this effect holds when we control for other proxies of financial constraints in addition unionized firms are associated with lower cash cash flow sensitivity which suggests that the higher investment cash flow sensitivity in unionized firms is primarily driven by the incentive of these firms to reduce liquidity and enhance bargaining power against the union we also show that the above union effects become more pronounced during labor contract negotiation years

multistage financing of technical start up companies in silicon valley abstract financing remains an issue that entrepreneurs face long after their initial financing has been obtained in technical companies that face changing customers competitors and technology the need to finance new products to replace earlier products can be of vital importance to growth and survival venture capital firms that invest in technical companies also recognize the need for subsequent financing to maintain growth and thus protect the initial investment this research explored both the venture capitalist s and the entrepreneur s viewpoints the principal questions asked in the research were 1 how are subsequent rounds of investment considered and made by venture capitalists and 2 what problems occur in the entrepreneur s search for subsequent funding a combination of in depth interviews and mailed questionnaires was used in the research to obtain responses from a sample of venture capitalists and entrepreneurs in silicon valley this approach produced observations on the venture capitalists methods of making risk return trade offs and on the reasons why entrepreneurs face problems in obtaining funding for second new products specifically it was found that venture capital firms reduce the risk associated with funding young companies by showing preferences for certain stages of financing or for funding single versus multiple round investments these preferences appear to be idiosyncratic and entrepreneurs must be careful to deal with venture capitalists whose tendencies are consistent with the entrepreneurs goals it was also found that a major problem faced by entrepreneurs seeking funding for second products is the effort required for the search this effort takes away from their ability to perform day to day management activities at a crucial time in the growth of the firm implications are drawn for improving the effectiveness of entrepreneurs and venture capitalists efforts as well as for future research

costly external finance corporate investment and the subprime mortgage credit crisis abstract we study the effect of the recent financial crisis on corporate investment the crisis represents an unexplored negative shock to the supply of external finance for non financial firms corporate investment declines significantly following the onset of the crisis controlling for firm fixed effects and time varying measures of investment opportunities consistent with a causal effect of a supply shock the decline is greatest for firms that have low cash reserves or high net short term debt are financially constrained or operate in industries dependent on external finance to address endogeneity concerns we measure firms financial positions as much as four years prior to the crisis and confirm that similar results do not follow placebo crises in the summers of 2003 2006 nor do similar results follow the negative demand shock caused by september 11 2001 the effects weaken considerably beginning in the third quarter of 2008 when the demand side effects of the crisis became apparent additional analysis suggests an important precautionary savings motive for seemingly excess cash that is generally overlooked in the literature

founder s human capital external investment and the survival of new high technology ventures the effect of founder characteristics in attracting external investment and enhancing survival of new high technology ventures is explored using human capital theory and signalling theory we test the effect of founder characteristics on external investment in and survival of new high technology ventures by tracking a random sample of 193 high technology start ups all participants in the israeli technology incubator program founder s business management expertise and academic status attracted external investment but founder s general technological expertise did not founder s business management expertise and general technological expertise positively affected venture survival but founder s academic status did not possible implications for entrepreneurs investors policy and further research are discussed

investment behavior observable expectations and internal funds we use earnings forecasts from securities analysts to construct a new measure of the neoclassical fundamentals that drive investment spending we find that investment responds significantly to our new measure of fundamentals but is insensitive to cash flow even for firms typically thought to be liquidity constrained these results have two key implications first fundamentals may be more important for investment spending than would be suggested by the results to date from investment q models second the positive cash flow effects obtained in such models may reflect a failure to control properly for fundamentals rather than the presence of financial constraints jel d92 e22

structural transformation and the rise of information technology abstract has the emergence of information technology changed the structure of employment and earnings in the us we propose a new index of occupation level it intensity and document several long term changes in the occupational landscape over the past decades using census and us klems micro data we show that i the bulk of productivity growth after 1950 is concentrated in it intensive sectors ii the share of workers in it jobs has expanded significantly with little or no pause and it jobs enjoy a large and growing earnings premium even after controlling for general task requirements e g cognitive non routine and iii the rise of the it intensive employment share is closely associated with declines in the manufacturing employment share while earnings premia for college educated and cognitive non routine workers have flattened in the aggregate since 2000 we show that they continued growing in it intensive jobs and that these jobs have played a key role in accounting for the surge of high tech service labor productivity we also use our it intensity index to estimate industry specific elasticities of substitution between it and non it intensive labor finding values of 1 6 in manufacturing and 1 3 in services finally we revisit a long standing question about the relationship between technological progress and productivity and provide evidence that occupation level it intensity is positively associated with output growth especially in the services sector

corporate investment with financial constraints sensitivity of investment to funds from voluntary asset sales we examine the importance of financial constraints for firm investment by looking at the relationship between investment expenditures and proceeds from voluntary asset sales asset sales provide a cleaner indicator of liquidity than cash flows since it appears not to be positively correlated with investment opportunities the cross sectional differences in firm investment are examined using an endogenous switching regression model with unknown sample separation we find that cash obtained from asset sales is a significant determinant of corporate investment and that the sensitivity of investment to proceeds from asset sales is significantly stronger for firms that are likely to be financially constrained

offshoring and outsourcing potentials evidence from german micro level data this paper provides two indicators that measure i offshoring potentials cross country geographical relocation and ii outsourcing potentials organisational relocation separately at the level of jobs occupations tasks and industries we use four waves of the bibb baua labour force survey in germany and apply principal component analysis based on a large set of potential determinants of offshoring and outsourcing derived from the literature our results show significant variation across these levels in the determinants of both dimensions we provide a comprehensive empirical classification of the determinants of how easily jobs can be offshored and outsourced this can serve as a basis for further research to investigate the economic effects of job offshoreability

offshoring tasks and the skill wage pattern the paper investigates the relationship between offshoring wages and the occupational task profile using rich individual level panel data our main results suggest that when only considering within industry changes in offshoring we identify a moderate wage reduction due to offshoring for low skilled workers though wage effects in relation to the task profile of occupations are not estimated with sufficient precision however when allowing for cross industry effects of offshoring i e allowing for labor mobility across industries negative wage effects of offshoring are quite substantial and depend strongly on the task profile of workers occupations a higher degree of interactivity and in particular non routine content effectively shields workers against the negative wage impact of offshoring

the market for interfirm asset sales partial sell offs and total liquidations abstract we investigate the valuation consequences of voluntary proposals to sell part or all of a corporation s assets for partial sell offs successful sellers and buyers reap statistically significant abnormal returns of 1 66 and 0 83 respectively unsuccessful sellers realize gains at the bid announcement of 1 41 that are lost at the offer termination in contrast proposals to liquidate the firm are associated with significant average abnormal returns of 12 24 we interpret these findings as evidence that asset sales are associated with the movement of resources to higher valued uses rather than as evidence of market mispricing before the divestiture announcements

accounting measurement basis market mispricing and firm investment efficiency in this paper we investigate how the accounting measurement basis affects the capital market pricing of a firm s shares which in turn affects the efficiency of the firm s investment decisions we distinguish two broad bases for accounting measurements input based and output based accounting we argue that the structural difference in the two measurement bases leads to a systematic difference in the efficiency of the investment decisions in particular we show that an output based measure has a natural advantage in aligning investment incentives because of its comprehensiveness the first best investment is achieved when the output based measure is noiseless and manipulation free in addition under an output based measure more accounting noise manipulation always leads to more inefficient investment choices therefore if an output based accounting measure is highly noisy and easy to manipulate in practice the induced investment efficiency can be quite low on the other hand an input based accounting measure while not as comprehensive may induce more efficient investment decisions than an output based measure if some noise is unavoidable in either measure the reason is twofold first input based measures may be associated with less noise and limited manipulation in practice second and more importantly we show that under

the importance of bundling in a gorman lancaster model of earnings the idea that the labor market of individuals can be decomposed into payments to separate productive attributes has an enduring appeal in economics assuming that demographic groups differ only in their endowments of productive characteristics it is possible to rationalize observed demographic earnings differentials without invoking the arguments that characteristics specific to a particular demographic group are direct objects of employer demand by aggregating skills over all demographic groups it is possible to produce a theory of the market determination of the prices of skills held in different amounts by different demographic groups this paper considers conditions under which characteristics are uniformly priced across sectors of a multisector economy the paper presents empirical evidence that rejects uniform pricing of characteristics as a description of the us labor market bundling may account for this evudence but other hypotheses do as well authors

spatial collocation and venture capital in the us biotechnology industry biotechnology firms operate in a high risk and high reward environment and are in a constant race to secure venture capital vc funds previous contributions to the literature show that the vc firms tend to invest locally in order to monitor their investments and to provide operating assistance to their target firms further biotechnology is a knowledge based industry that tends to exhibit spatial clusters and the firms in such industries may collocate to benefit from gaining access to local markets for specialized inputs e g skilled researchers and from local knowledge spillovers and network externalities if such gains exist we expect that the collocated firms should exhibit positively correlated performance including in their ability to attract venture capital funds the purpose of this paper is to empirically measure the strength and spatial extent of the relationships among the amount of funds raised by proximate biotechnology firms we model these relationships with a spatial autoregression sar model and we control for characteristics of the biotechnology firms and the vc firms that provide their funds as well as site specific factors based on our fitted sar model we find that the amount of venture capital raised by a particular biotechnology firm is significantly influenced by the number of vc firms and the vc funding levels raised by biotechnology firms located within a 10 mile radius but these relationships are not statistically significant beyond this range

the evolution of the human capital of women the labour market attachment of females has increased dramatically over the last half century converging to a pattern similar to that of males human capital theory predicts an associated increase in human capital investment by females and a convergence in the life cycle human capital investment profiles of males and females this paper explores wage based and job skills based approaches to measuring the increased supply of efficiency units of human capital by females over the last four decades results suggest that the magnitude of the contribution of the increased human capital of women to post war economic growth is substantially underestimated by conventional methods of measuring human capital and labour inputs a complete picture of the evolution of the human capital of women requires new approaches to measuring their human capital l evolution du capital humain des femmes au cours des cinquante dernieres annees l activite des femmes sur le marche du travail a considerablement augmente convergeant vers un modele similaire a celui des hommes correlativement la theorie du capital humain anticipe deux phenomenes une augmentation de l investissement des femmes dans le capital humain ainsi qu une convergence des profils d investissement dans le capital humain par les deux sexes tout au long de la vie afin d evaluer la hausse de productivite du capital humain des femmes au cours des quarante dernieres annees cet article explore les approches basees a la fois sur le salaire et les competences professionnelles les resultats suggerent que l ampleur de la hausse du capital humain des femmes dans l economie d apres guerre a ete sensiblement sous evaluee par les methodes de calcul traditionnelles a la fois du capital humain et du facteur travail ainsi pour mesurer l evolution du capital humain des femmes de facon plus globale de nouvelles approches sont necessaires

target behavior and financing how conclusive is the evidence the notion that firms have a debt ratio target that is a primary determinant of financing behavior is influential in finance yet how definitive is the evidence we address this issue by generating samples where financing is unrelated to a firm s current debt ratio or a target we find that much of the available evidence in favor of target behavior based on leverage ratio changes can be reproduced for these samples taken together our findings suggest that a number of existing tests of target behavior have no power to reject alternatives

the effect of low skilled immigration on u s prices evidence from cpi data i exploit the large variation across u s cities and through time in the relative size of the low skilled immigrant population to estimate the causal effect of immigration on prices of nontraded goods and services using an instrumental variables strategy i find that at current immigration levels a 10 percent increase in the share of low skilled immigrants in the labor force decreases the price of immigrant intensive services such as housekeeping and gardening by 2 percent wage equations suggest that lower wages are a likely channel through which these effects take place however wage effects are significantly larger for low skilled immigrants than for low skilled natives implying that the two are imperfect substitutes

accounting for complementary skill sets evaluating individual marginal value to a team in the national basketball association identifying an individual worker s contribution to firm production can be difficult in a team setting where spillovers in labor productivity exist among team members this paper studies a model of labor productivity where workers have heterogeneous abilities and can differently affect the productivity of their fellow teammates applying the model to the setting of the national basketball association nba i can identify the marginal value that a basketball player brings to a particular team lineup both through his own individual contributions and his complementary contribution to teammates productivity estimates from the model imply that teammates have a significant impact on individual player productivity and that taking into account spillovers across teammates is important to assessing both overall team productivity and an individual player s contribution to team productivity i then evaluate whether player complementarities are valued in the nba labor market in terms of higher salaries and find that they are undervalued and that players are instead paid mainly for their individual offensive production this creates an asymmetry between player incentives and the team objective to assess the size of this inefficiency the top trading cycle algorithm of shapley and scarf 1974 is used to identify a pareto optimal matching between players and teams that accounts for the complementarities between heterogeneous players skill sets jel j30 l25 l83 m51

putting tasks to the test human capital job tasks and wages using original representative survey data we document that analytical routine and manual job tasks can be measured with high validity vary substantially within and between occupations are significantly related to workers characteristics and are robustly predictive of wage differences between occupations and among workers in the same occupation we offer a conceptual framework that makes explicit the causal links between human capital endowments occupational assignment job tasks and wages which motivate a roy model of the allocation of workers to occupations we offer two simple tests of the model s gross predictions for the relationship between tasks and wages both of which receive qualified empirical support

strategic shirking a theoretical analysis of multitasking and specialization we provide a new theory to explain why firms multitask workers instead of specializing them workers overperform in tasks they like and underperform in tasks they dislike to favorably influence future job assignments anticipating this firms may find it optimal to commit to future multitasking to induce workers to appropriately allocate effort early in the employment relationship we show that when the product market is volatile so that future product prices are uncertain the firm s ability to credibly commit to a multitasking strategy diminishes this generates a negative relationship between multitasking and product market volatility consistent with recent empirical evidence

the wage impact of undocumented workers evidence from administrative data using administrative individual level longitudinal data from the state of georgia this article finds that rising shares of undocumented workers results in higher earnings for documented workers but by a small amount a one percentage point increase in the share of undocumented workers in a documented worker s county industry results in an average wage boost of 0 44 within the firm a one percentage point increase in the percent of undocumented workers employed by the firm boosts wages by 0 09 0 11 0 12 and 0 04 in low medium and high skill firms respectively potential explanations for a positive wage impact are discussed

validation of the venture evaluation model in korea abstract this article examines the validity of the venture evaluation model in korea by directly comparing the relative importance of evaluation criteria on the funding decision with the relative importance of factors influencing venture s empirical performance specifically we first identify the relative importance of evaluation criteria based on whether a deal is accepted or rejected current evaluation model next we derive the relative importance of those criteria revealed in the empirical performance based on the success failure of ventures that overlap with the deals originally used as accepted cases performance based model finally to better understand the differences between the two models we measure the general perceptions of venture capitalists on the importance of those criteria without regard to specific deals normative model to identify potentially important criteria we reviewed the existing related studies on evaluation criteria and we interviewed 10 venture capitalists as a result we selected 31 evaluation items the questionnaire consists of two parts and deals with the following four cases in part a 1 1 case 1 general perceptions concerning the 31 criteria in part b 2 2 case 2 one of the most successful ventures 3 3 case 3 one of the least successful ventures 4 4 case 4 one of the rejected ventures using a five point scale we asked the respondents to rate the 31 criteria based on their general perceptions without referring deals case 1 and on the specific deals they had handled cases 2 3 and 4 to prevent any firm or respondent from affecting the results more than it ought to we distributed the questionnaire to each firm in proportion to the investment amounts we also asked the respondents to fill out only one questionnaire including four cases seventy four venture capitalists including 10 interviewed responded to this questionnaire they have worked as investment directors or managers in the top rated 20 venture capital companies selected according to investment amounts on the basis of the ratings of 31 criteria for the previous four cases we developed three investment models first the current evaluation model reveals which criteria are more important in deciding whether or not to fund the model measures the relative importance of evaluation factors in discriminating between the accept case 2 and case 3 and the reject case 4 decision second the performance based model consists of the relative weights of evaluation factors influencing the two performance categories success case 2 and failure case 3 this model shows the relative importance of evaluation criteria that are reflected in the venture s empirical performance finally we identify the normative model revealing the venture capitalists general perceptions concerning the importance of individual criteria in light of their past field experiences case 1 by comparing the three models we find that the importance of these criteria revealed from venture capitalists perceptions and empirical performances is fairly similar but not sufficiently reflected in the actual deal evaluation in particular the entrepreneur related characteristics are not considered the most important in evaluating venture proposals according to the current evaluation model but they do turn out to be the most important factors in evaluating empirical performance this is in strong contrast to the findings of some existing studies which contend that the entrepreneurrelated criteria ultimately determine the funding decision instead the result confirms the previous assertion that the evaluation of managerial capability is the most challenging task in the venture selection process in the current evaluation model financing ability is considered more important than either superiority of product and technology or production capability contrary to venture capitalists perceptions and empirical performance results therefore it seems necessary to raise the level of specialization of venture capital firms through the acquisition of managerial skills from developed countries and by enhancing the technical background of individual venture capitalists

accounting information disclosure and the cost of capital in this paper we examine whether and how accounting information about a firm manifests in its cost of capital despite the forces of diversification we build a model that is consistent with the capital asset pricing model and explicitly allows for multiple securities whose cash flows are correlated we demonstrate that the quality of accounting information can influence the cost of capital both directly and indirectly the direct effect occurs because higher quality disclosures affect the firm s assessed covariances with other firms cash flows which is nondiversifiable the indirect effect occurs because higher quality disclosures affect a firm s real decisions which likely changes the firm s ratio of the expected future cash flows to the covariance of these cash flows with the sum of all the cash flows in the market we show that this effect can go in either direction but also derive conditions under which an increase in information quality leads to an unambiguous decline in the cost of capital

determinants of venture capital firms preferences regarding the industry diversity and geographic scope of their investments abstract competition is intensifying in the venture capital industry in the u s the number of venture capital firms vcfs tripled from 1980 to 1989 supplier power in the form of institutional investors such as pension funds continues to grow foreign venture capital has grown to the extent that commitments to foreign vcfs exceeded domestic commitments in both 1988 and 1989 further alternative sources of financing for entrepreneurs such as individual investors angels corporations and strategic alliances are increasingly viable options vcfs face pressure to seek lower risk investments improve rates of return and provide value to new venture development surprisingly few scholarly studies have begun to investigate the strategies vcfs are aiming to implement in order to deal with this increasing pressure building on the premise that decisions regarding product market scope are a key component of firm strategy hofer and schendel 1978 this study examined 169 domestic vcfs in order to identify factors that might explain variations in preferences regarding the industry diversity and geographic scope of their investments the sample drawn from california massachusetts and texas represented about 27 of all u s based vcfs in 1987 the year in which the data were gathered in terms of the total size of investment portfolio the average for these 169 vcfs was 69 8 million which is statistically indistinguishable from the u s average of 65 million results indicate that 1 vcfs specializing in early stage ventures prefer less industry diversity and narrower geographic scope relative to other vcfs 2 corporate vcfs i e those owned by non financial corporations prefer less industry diversity but broader geographic scope relative to non corporate vcfs 3 larger vcfs prefer greater industry diversity and broader geographic scope than do smaller vcfs and 4 provision of small business investment companies sbic financing by the vcf has no impact on preferences regarding industry diversity but is associated with a preference for narrower geographic scope one implication of these results is that vcfs in the u s are not homogeneous as regards the intended product market scope of their portfolios this in turn holds implications not only for vcfs but also for their suppliers limited partners buyers entrepreneurs and policy makers vcfs can no longer rely on haphazard investment schemes they need to attract investors by virtue of the benefits offered by their portfolio strategy and they need to attract superior investments via offering valueadded services and know how potential investors in venture capital will want to examine for example the impact on risk and return of investing smaller amounts in several vcfs at one extreme versus making one large investment in a very diversified vcf at the other extreme the results of this and other studies suggest that outcomes timing magnitude and riskiness of returns of choosing such alternatives will vary widely and will depend in great part on the strategies of the vcfs involved it will not be possible for investors to make wise choices without a full examination of their own objectives and of the profiles of vcfs entrepreneurs with the most attractive ventures have alternative sources of financing to consider and should weigh the benefits of being financed and supported by various vcfs as part of the vcfs portfolios knowing a vcf s preferences regarding product market scope improves their chances of approaching and selecting the right fit and for those entrepreneurs with a narrower set of options such knowledge may make the difference between receiving and not receiving financing in a timely manner finally policy makers may be able to make use of knowledge of the forces that influence the investment strategies of vcfs presently concerns for policy makers may include the gap in seed capital increased foreign presence in the u s market and the export of promising innovative technology via alliances with foreign firms all of these factors are influenced by the strategies pursued by vcfs as they jockey for position in the increasingly competitive venture capital market

the economics of immigration this literature review concerns the impact of immigration on the economy of the host country focusing on the experience of the united states the emphasis is on the period from the 1970s to the 1990s the author shows that research earlier in this period generally concluded that the economic effects of immigration were positive but that more recent research on later migrations have generally concluded that immigration may be having an adverse effect on the earnings of native unskilled workers and be placing an increased burden on welfare programs the importance of such economic analysis for the formulation of appropriate migration policies is stressed

corporate structure liquidity and investment evidence from japanese industrial groups this paper presents evidence suggesting that information and incentive problems in the capital market affect investment we come to this conclusion by examining two sets of japanese firms the first set has close financial ties to large japanese banks that serve as their primary source of external finance and are likely to be well informed about the firm the second set of firms has weaker links to a main bank and presumably faces greater problems raising capital investment is more sensitive to liquidity for the second set of firms than for the first set the analysis also highlights the role of financial intermediaries in the investment process

the growing importance of social skills in the labor market the labor market increasingly rewards social skills between 1980 and 2012 jobs requiring high levels of social interaction grew by nearly 12 percentage points as a share of the u s labor force math intensive but less social jobs including many stem occupations shrank by 3 3 percentage points over the same period employment and wage growth were particularly strong for jobs requiring high levels of both math skill and social skills to understand these patterns i develop a model of team production where workers trade tasks to exploit their comparative advantage in the model social skills reduce coordination costs allowing workers to specialize and work together more efficiently the model generates predictions about sorting and the relative returns to skill across occupations which i investigate using data from the nlsy79 and the nlsy97 using a comparable set of skill measures and covariates across survey waves i find that the labor market return to social skills was much greater in the 2000s than in the mid 1980s and 1990s

investment cash flow sensitivities are useful a comment on kaplan and zingales arecent paper in this journal by kaplan and zingales reexamines a subset of erms from work of fazzari hubbard and petersen and criticizes the usefulness of investment cash eow sensitivities for detecting enancing constraints we show that the kaplan and zingales theoretical model fails to capture the approach employed in the literature and thus does not provide an effective critique moreover we describe why their empirical classiecation system is eawed in identifying both whether erms are constrained and the relative degree of constraints across erm groups we conclude that their results do not support their conclusions about the usefulness of investment cash eow sensitivities in a recent paper in this journal kaplan and zingales 1997 hereinafter kz argue that investment cash eow sensitivities do not provide useful evidence about the presence of enancing constraints because kz use a subset of the same erms and the same regressions as fazzari hubbard and petersen 1988 hereinafter fhp and claim page 176 that fhp can legitimately be considered the parent of all papers in this literature it is appropriate that we respond based on a simple theoretical model kz reach the provocative conclusion page 211 that the investment cash eow sensitivity criterion as a measure of enancial constraints is not well grounded in theory in section i we show that the kz model does not capture the theoretical approach employed in fhp and many subsequent studies most of the kz paper attempts to show that empirical investment cash eow sensitivities do not increase monotonically with the degree of enancing constraints within the 49 low dividend erms from the fhp sample in section ii we explain why the kz classiecation of the degree of constraints is eawed in identifying both whether or not erms are constrained absolute constraints as well as the relative degree of constraints across erms as a result we argue in section iii that there is no expected ex ante pattern for the

how sensitive is investment to cash flow when financing is frictionless i analyze the sensitivity of a rm s investment to its own cash ow in the benchmarkcase where nancing is frictionless this sensitivity has been proposed as a measure of nancing constraints in earlier studies i nd that the investment cash ow sensitivities that obtain in the frictionless benchmarkare very similar both in magnitude and in patterns they exhibit to those observed in the data in particular the sensitivity is higher for rms with high growth rates and low dividend payout ratios tobin s q is shown to be a more noisy measure of near term investment plans for these rms does a high sensitivityof a rm s investment to its own cash ow indicate that the rm is nancially constrained a large body of research starting with fazzari hubbard and petersen 1988 hereafter fhp suggests that rms facing nancing constraints should exhibit high investment cash ow sensitivities re ecting the wedge between the costs of external and internal funds empirical ndings seem to give support to this hypothesis since rms classi ed as constrained on a priori criteria such as size dividend payout or leverage do have higher cash ow sensitivities even after controlling for their investment opportunities by conditioning on tobin s q however the reliability of these results critically depends on whether q is a proper control for the investment opportunity set if q performs worse for certain classes of rms higher sensitivities may obtain for these rms simply because cash ow re ects information about investment opportunities this critique is not new in his discussion of fhp poterba 1988 was the rst to point out that measurement error in q may cloud the empirical results similar concerns have been raised in subsequent studies as well while the qualitative point is well known its quantitative impact on the investment cash ow sensitivity has not been analyzed can the linkbetween cash ow and the investment opportunity set account for the observed magnitudes of the sensitivity or are these magnitudes too large to be explained without nancing frictions

estimating irreversible investment with financial constraints an application of switching regression models this analysis investigates irreversible investment with financial constraints when investment is irreversible zero investment can be optimal and investment becomes lumpy because external funds are not a perfect substitute for internal funds financially constrained firms invest differently than unconstrained firms to incorporate both irreversibility and financial constraints into estimations the analysis develops a switching regression model that depends on the real options theory of capital investment the analysis investigates three us industries the oil refining communications equipment manufacturing and semiconductor manufacturing industries the analysis shows that internal funds affect investment if a firm is financially constrained
