are the self employed really jacks of all trades testing the assumptions and implications of lazear s theory of entrepreneurship with german data using a large representative german data set and various concepts of self employment this paper tests the jack of all trades view of entrepreneurship by lazear am econ rev 94 2 208 211 2004 consistent with its theoretical assumptions we find that self employed individuals perform more tasks and that their work requires more skills than that of paid employees in contrast to lazear s assumptions however self employed individuals do not just need more basic but also more expert skills than employees our results also provide rather limited support for the idea that human capital investment patterns differ between those who become self employed and those ending up in paid employment

modelling long run scenarios this paper intends to draw overall lessons from a long term study on co2 emission in france a country with a rather low energy gdp ration and in which transition to non fossil based production of electricity has been achieved more generally it points out the importance of possible bifurcation effects and draws methodological and policy implications from these statements it discusses modelling approaches to the linkages between energy and the rest of economy and addresses the issue of difficulties in cost assessment analysis in the presence of several baseline scenarios finally it proposes a more encompassing definition of no regrets policies

the role of energy in productivity growth the objective of this paper is to analyze the role of energy in the growth of productivity the special significance of energy in economic growth was first established in the classic study energy and the american economy 1850 1975 by sam schurr and his associates 1960 at resources for the future for the period from 1920 to 1955 schurr noted that energy intensity of production had fallen while both labor and total factor productivity were rising the simultaneous decline in energy intensity and labor intensity of production ruled out the possibility of explaining the growth of productivity solely on the basis of substitution of less expensive energy for more expensive labor since the quantity of both energy and labor inputs required for a given level of output had been reduced technical change is also a critical explanatory factor an alternative explanation for growth of output with declining energy and labor intensity required an examination of the character of technical change this examination was motivated by the fact that from 1920 to 1955 the utilization of electricity had expanded by a factor of more than ten while consumption of all other forms of energy only doubled the two key features of technical change during this period were that the thermal efficiency of conversion of fuels into electricity increased by a factor of three and that the unusual characteristics of electricity had made it possible to perform tasks in altogether different ways than if the fuels had to be used directly schurr 1983 p 3 schurr 1982 has recently extended the analysis of energy and the american economy through 1981 for the period through 1969 his conclusions are as follows although the inverse relationship between total factor productivity and energy intensity virtually disappeared during the 1953 1969 period it is still noteworthy that high rates of improvement in total factor productivity were essentially not associated with increases in energy intensity 1982 p 6 schurr 1982 has analyzed the experience of the u s economy in the aftermath of the oil embargo of 1973 he points out that energy intensity of production has fallen steadily since 1973 and that the rate of decline accelerated sharply after the second oil price shock in 1979 following the iranian revolution he goes on to point out that

the higher returns to formal education for entrepreneurs versus employees how valuable is formal education for entrepreneurs income relative to employees and if the income returns to formal education are different for entrepreneurs vis a vis employees what might be a plausible explanation to explore these questions we analyze a large representative us panel we show that entrepreneurs have higher returns to formal education than employees we refer to this as the entrepreneurship returns puzzle we run post hoc analyses to explore a number of potential explanations of this puzzle indirectly our analysis indicates that the higher returns to formal education for entrepreneurs might be due to the fewer organizational constraints they face leading to more personal control over how to use their human capital compared to employees

the chronology and intellectual trajectory of american entrepreneurship education 1876 1999 abstract since the first entrepreneurship class held in 1947 the academic discipline of entrepreneurship s growth is described using a chronology of three domains courses supplemental infrastructures and publications a 100 item chronology of entrepreneurship education in the usa from 1876 through 1999 is offered and analyzed the major findings are 1 in the usa the field has reached maturity and 2 growth is likely outside business schools and outside the usa the major problems include a glut of journals a narrowing focus on top tier publications potential american stagnation and a shortage of faculty overall exacerbated by a shortage of phd programs

entrepreneurship selection and performance a meta analysis of the impact of education in developing economies this meta analytical review of empirical studies of the impact of schooling on entrepreneurship in selection and performance in developing economies looks at variations impact across specific characteristics of the studies a marginal year of schooling in developing economies raises enterprise income by an average of 5 5 percent which is close to the average return in industrial countries the return varies however by gender rural or urban residence and the share of agriculture in the economy furthermore more educated workers typically end up in wage employment and prefer nonfarm entrepreneurship to farming the education effect that separates workers into self employment and wage employment is stronger for women possibly stronger in urban areas and also stronger in the least developed economies where agriculture is more dominant and literacy rates are lower

are women graduates jacquelines of all trades challenging lazear s view on entrepreneurship this study challenges the basic reasoning behind lazear s theory on entrepreneurship 2005 based on the key motive of maximizing one s lifetime income lazear posits that individuals with a balanced set of skills should have a higher probability of being self employed his jack of all trades hypothesis presumes that entrepreneurs need sufficient knowledge in a variety of areas to succeed while paid employees benefit from being specialists in a certain area demanded by the labor market because most women led businesses are neither based on the motive of making money nor are they growth oriented we argue that maximizing their lifetime income is not the main motivation of many women to start a business however we argue that lazear s theory can be extended to motivations that are mostly stated for women entrepreneurs as well we apply it to a specific representative sample of 1384 women graduates in germany and test our hypothesis with logit regression a dichotomized measure indicating whether a women graduate was self employed n 706 or not n 678 served as the dependent variable our results widely confirm lazear s assumption for women graduates who run relatively small businesses in terms of sales and employment professional training balanced industry experience and balanced entrepreneurship based self efficacy increase the probability of being self employed solo self employed tend to have balanced industry experience more often than those being in a team or having employees lazear s theory has male as the norm and as such does not readily apply to the case of women but could and should be extended to women s specifics

growth accounting with intermediate inputs and the transmission of technical change abstract the aggregate rate of total factor productivity growth tfpg when there are intermediate inputs can be expressed either as a weighted average or as a weighted sum of the sectoral rates depending on the choice of sectoral rates being weighted the agrument that there is a magnification effect due to the transmission of tfpg through the intersectoral flows among sectors is therefore to be more illusory than real

do overarching mitigation objectives dominate transport specific targets in the eu this research investigates if the stringent 2020 and 2050 overarching co2 mitigation objectives set out by the european union dominate its 2010 to 2020 targets specific to the transportation arena specifically its biofuel penetration objectives and gram co2per kilometre emission caps using a dynamic recursive general equilibrium model imaclim r we demonstrate that these overarching targets do not dominate the interim transportation targets when the carbon policy triggering compliance with the mitigation objectives boils down to the theoretical least cost option of uniform carbon pricing ground transportation is confirmed as quite insensitive to high carbon prices even when such prices are applied over a long term it is tempting to conclude that pursuing the mitigation objectives specific to transportation will impose unnecessary costs however because of the second best conditions prevailing in actual economies and of the risk of lock in in carbon intensive trajectories we conclude with the urgent need for some ambitious transport specific policy design research agenda

task specific human capital since gary becker s 1964 seminal work the theoretical and empirical literature on human capital has focused almost exclusively on general purpose and firm specific human capital in this paper we discuss the implications of a third type of human capital which we call task specific and which we believe is potentially as commonplace and as important as the two classic types by task specific human capital we mean that some of the human capital an individual acquires on the job is specific to the tasks being performed as opposed to being specific to the firm in other words task specific human capital is the simple but plausible idea that much of the human capital accumulated on the job is due to task specific learning by doing the idea of task specific human capital is closely related to occupationand industryspecific human capital in each case human capital is specific to the nature of the work not specific to the firm hence when capital is accumulated multiple firms value the capital so most or even all of the value of the capital will be reflected in the worker s wage the main difference between the idea of task specific human capital and occupationand industryspecific human capital is in how the idea is applied we argue that task specific human capital has much wider applicability than suggested so far by the occupationand industry specific human capital literatures the specific issues we address are cohort effects job design and promotions another argument in the literature closely related to ours is the classic argument of adam smith 1776 in the wealth of nations concerning returns to specialization smith s argument was that due to learning by doing at the level of the task productivity can be enhanced by having each job entail fewer tasks we believe that smith was correct in focusing on learningby doing at the level of the task as an important idea for thinking about organizations the goal of our paper is to describe some of the other implications of this idea for the design and operation of organizations

the effectiveness of active labour market policies a meta analysis this paper provides a meta analysis of microeconometric evaluation studies on the effectiveness of active labor market policies the analysis is built upon a systematically assembled data set of causal impact estimates from 57 experimental and quasi experimental studies providing 654 estimates published between january 1990 and december 2017 we distinguish between the short and longer term impacts in our analysis at 6 12 24 and 36 months after program start after correcting for publication bias and country specific macroeconomic characteristics subsidized labor and public employment programs have negative short term impacts which gradually turn positive in the longer run schemes with enhanced services including job search assistance and training programs do not have these negative short term effects and stay positive from 6 until 36 months after program start

do entrepreneurs create jobs many countries support the creation of new firms such policy is based on the presumption that the total number of jobs increases when a person moves from unemployment or regular employment to self employment in this paper the link between self employment and overall employment is analyzed the empirical analysis based on panel data of swedish counties from 1976 1995 pays particular attention to simultaneity issues the results suggest that self employment may have a significant positive effect on overall employment

the impact of electric power on productivity according to the historical record the increased use of energy in general and electric power in particular stands as one of the key factors in productivity growth growth accountants however find little support for this view rejecting claims that the productivity slowdown can be attributed to the lower rate of growth of the energy input in us manufacturing in this study an attempt at reconciling the historical record with the empirical facts is made specifically the commonly used factor income shares in the relevant divisia input growth index are replaced by the estimated output input elasticities the latter attribute a considerably larger role to electric power than previous studies indicated these are then used to reevaluate the sources of growth in us manufacturing

review of economic growth and energy consumption a panel cointegration analysis for eu countries abstract this paper examines the long run relationship between energy consumption and real gdp including fixed capital and total employment for 18 eu countries from 1995 to 2012 the analysis was based on the panel unit root tests panel cointegration test and fully modified ordinary least squares fmols estimator and dynamic ordinary least squares dols estimator data were analyzed in three groups all sample visegrad countries v4 and old 14 eu countries indeed the results demonstrate that economic growth and the variables energy consumption gross fixed capital are cointegrated for the whole panel of countries as well as for the two selected groups of countries furthermore the panel fmols and dols estimators reveal that the relationship between energy consumption gross fixed capital and economic growth is positive

releasing constraints to growth or pushing on a string policies and performance of mexican micro firms abstract using firm level data from mexico this paper investigates the firm characteristics associated with participation in credit markets access to training tax payments and membership in business associations we find that firms which participate in these institutions exhibit significantly higher profits moreover firms that borrow from formal or informal sources and those that pay taxes are significantly more likely to stay in business but firms that received credit exhibit lower rates of income growth these results persist when firm characteristics that are arguably correlated with unobserved entrepreneurial ability are controlled for our findings suggest that the significant within country differences in firm productivity observed in developing economies are due in part to market and government failures that limit the ability of micro firms to reach their optimal sizes

on the design of hierarchies coordination versus specialization we consider an economy that has to decide how assets are to be used agents have ideas but these ideas conflict we suppose that decision making authority is determined by hierarchy each asset ha

the efficiency of capital allocation in this paper we present an intertemporal general equilibrium model of the u s economy the purpose of this model is to analyze the efficiency of capital allocation we have implemented our model econometrically for annual data covering the period 1955 80 the model encompasses the critical features of u s tax laws applicable to income from capital equilibrium is determined by market clearing conditions for consumption and investment goods and for capital and labor services in each time period under perfect foresight there exists a unique balanced growth equilibrium corresponding to any stationary tax policy an intertemporal general equilibrium model of the u s economy is presented in this paper the purpose of this model is to analyze the efficiency of capital allocation the model is kindred in spirit to the model of the swedish economy developed by ragnar bentzel 1978

energy prices and productivity growth the sharp decline in economic growth since 1973 presents a problem comparable in scientific interest and social importance to the problem of unemployment in the great depression of the 1930s conventional methods of economic analysis have been tried and have been found to be inadequate this paper outlines a new framework for understanding the slowdown in economic growth we find that the fall in u s economic growth since 1973 has been due to the dramatic decline in productivity growth within the new framework we identify higher energy prices as an important determinant of the productivity slowdown

is public r d a complement or substitute for private r d a review of the econometric evidence is public r d spending complementary and thus additional to private r d spending or does it substitute for and tend to crowd out private r d conflicting answers are given to this question we survey the body of available econometric evidence accumulated over the past 35 years a framework for analysis of the problem is developed to help organize and summarize the findings of econometric studies based on time series and cross section data from various levels of aggregation laboratory firm industry country the findings overall are ambivalent and the existing literature as a whole is subject to the criticism that the nature of the experiment s that the investigators envisage is not adequately specified we conclude by offering suggestions for improving future empirical research on this issue

success in entrepreneurship a complementarity between schooling and wage work experience what makes a successful entrepreneur using danish register data we find strong support for the hypothesis that theoretical skills from schooling and practical skills acquired through wage work are complementary inputs in the human capital earnings function of entrepreneurs in fact we find that schooling only pays off in combination with wage work experience as the returns to schooling are insignificant when the entrepreneur has no wage work experience the results are extremely robust toward more flexible specifications including fixed effect estimations dealing with unobserved heterogeneity furthermore the interaction term is negligible for non entrepreneurs suggesting that the complementarity between wage work experience and schooling is a distinctive characteristic of entrepreneurs

the demand for capital labor and energy in european manufacturing industry before and after the oil price shocks the price and substitution elasticities for factor inputs capital labor fuels and electricity are estimated for total manufacturing industry on the basis of a pooled crosscountry time series analysis for nine west european countries the impact of the economic disturbances in the 1970s on the price sensitivity of demand is analyzed by estimating a translog cost function for two separate periods 1960 72 and 1973 80 hicks neutral technical change is rejected for both periods the results indicate some quite significant changes in the elasticities over the two periods

the impact of entrepreneurship education on entrepreneurship skills and motivation this paper analyzes the impact of a leading entrepreneurship education program on college students entrepreneurship skills and motivation using an instrumental variables approach in a difference in differences framework we exploit that the program was offered to students at one location of a school but not at another location of the same school location choice and thereby treatment is instrumented by the relative distance of locations to parents place of residence the results show that the program does not have the intended effects the effect on students self assessed entrepreneurial skills is insignificant and the effect on the intention to become an entrepreneur is even negative

thinking about the firm a review of daniel spulber s the theory of the firm in this review i describe how economists have moved beyond the firm as a black box to incorporate incentives internal organization and firm boundaries i then turn to the way that the theory of the firm is treated in daniel spulber s book the theory of the firm microeconomics with endogenous entrepreneurs firms markets and organizations spulber s goal is to explain why firms exist how they are established and what they contribute to the economy to accomplish this spulber defines a firm to be a transaction institution whose objectives differ from those of its owners for spulber this separation is the key difference between the firm and direct exchange between consumers i raise questions about whether this is a useful basis for a theory of the firm jel d21

returns to schooling in self employment abstract this paper challenges the idea that returns to schooling in self employment are similar to those in wage work by establishing a non linear relationship with very low returns for most educational levels in self employment we conclude that previous log linear specifications in the self employment literature have missed significant variation in the true relationship between education and earnings

are nascent entrepreneurs jacks of all trades a test of lazear s theory of entrepreneurship with german data in a recent paper edward lazear proposed the jack of all trades view of entrepreneurship based on a coherent model of the choice between self employment and paid employment he shows that having a background in a large number of different roles increases the probability of becoming an entrepreneur the intuition behind this proposition is that entrepreneurs must have sufficient knowledge in a variety of areas to put together the many ingredients needed for survival and success in a business while for paid employees it suffices and pays to be a specialist in the field demanded by the job taken this study contributes to the entrepreneurship literature by empirically testing lazear s hypothesis using a large recent representative sample of the german population the empirical estimation takes the rare events nature of becoming a nascent entrepreneur and the regional stratification of the sample into account the results illustrate the statistical significance and economic importance of the jack of all t

estimates of the economic returns to schooling from a new sample of twins this paper uses a new survey to contrast the wages of genetically identical twins with different schooling levels multiple measurements of schooling levels were also collected to assess the effect of reporting error on the estimated economic returns to schooling the data indicate that omitted ability variables do not bias the estimated return to schooling upward but that measurement error does bias it downward adjustment for measurement error indicates that an additional year of schooling increases wages by 12 to 16 percent a higher estimate of the economic returns to schooling than has been previously found copyright 1994 by american economic association

redefining business success distinguishing between closure and failure new firms are believed to have high closure rates and these closures are believed to be failures but two u s census bureau data sources illustrate that these assumptions may not be justified the business information tracking series bits showed that about half of new employer firms survive beyond four years and the characteristics of business owners cbo showed that about a third of closed businesses were successful at closure the cbo also made it possible to compare results of models of business survival and business success but because of non response bias logit models were used similar to previous studies firms having more resources that were larger with better financing and having employees were found to have better chances of survival factors that were characteristic of closure such as having no start up capital and having a relatively young owner were also common in businesses considered successful at closure hence few defining factors can be isolated leading to true failures the significant proportion of businesses that closed while successful calls into question the use of business closure as a meaningful measure of business outcome it appears that many owners may have executed a planned exit strategy closed a business without excess debt sold a viable business or retired from the work force it is also worth noting that such inborn factors as race and gender played negligible roles in determining survivability and success at closure

an examination of the substitutability of founders human and financial capital in emerging business ventures abstract undoubtedly access to financial capital and other resources is an important antecedent of new venture performance indeed inadequate financial resources often are cited as a primary reason why emerging businesses fail barren 1989 mcqueen 1989 otterbourg 1989 rujoub cook and hay 1995 yet there is some feeling among scholars that competent founders will find a way of coming up with necessary resources and capital chandler and hanks 1994 timmons 1990 thorne 1989 in this study we seek to better understand and provide insight into the factors that determine the amount of money needed to start a business and the factors that drive the decisions of whether such funding should come from founder savings or from outside sources we explore two questions 1 what factors are associated with the amount of initial capital raised and 2 what factors determine the mix of founder savings versus financial capital from outside sources that create the initial capital structure we seek to answer these questions using a sample of 102 manufacturing and service firms between 3 and 7 years of age these firms were categorized as manufacturing retail wholesale and business services in general the evidence supports our hypotheses the amount of financial capital at start up varies by industry of key importance in this study human and financial capital appear to be substitutable the analysis shows that on average firms with high levels of founder human capital and low levels of initial financial capital perform similarly to firms that have low levels of founder human capital and high levels of financial capital subgroup analysis provides insights into the degree of substitutability this finding suggests that founders with strong background experience may be able to start businesses that survive and thrive with less financial capital than their less experienced counterparts the proportion of initial capital provided by the founder differs significantly across industry types in more capital intensive industries founders provide a smaller proportion of the start up capital interestingly the amount of initial capital provided by the founder does not vary significantly across industry types this suggests that the amount of initial capital provided by the founder may result from contributing all they can give to the business which appears to be similar across business types finally founders perceptions of their ability to recognize and take advantage of opportunity are positively related to the proportion of initial capital provided by the founder this research provides insights into the factors that appear to drive the initial capital intensity and structure to provide better understanding of this phenomenon future research could investigate such practices as bootstrapping asset sharing or other techniques that allow founders to control resources without requiring ownership

the impact of entrepreneurship programs on minorities we document the impact of an entrepreneurship training program on startup activity of minorities females and non caucasians we compare entrepreneurial activity between applicants who are accepted into the program with applicants who are program finalists but not accepted we find that the effect of the program is small for minorities in the short run however the effect of the program is more pronounced for minorities likelihood of longer run startup activity whereas the effect on non minorities is small and statistically insignificant we suggest that such programs are most effective for individuals that may otherwise have limited access to entrepreneurial opportunities

the impact of disaggregated energy on productivity abstract the issue of the productivity slowdown of the 1970s and 1980s has received considerable analysis in the literature however the issue of the impact of energy on productivity is still debated this study contributes to the debate with the hope that some sight could be provided through disaggregating the factor input energy into two components a petroleum component and a non petroleum component by analysing labour productivity growth total factor productivity growth and labour intensity ratios the disaggregated energy component can be viewed as a major influence in explaining the productivity decline

international technological knowledge differences and economic growth comparisons usa versus west germany and sweden versus norway 1963 1988 the main interest in this paper is governed by the methodology for making evolutive growth comparisons in the international context the paper analysis differences in levels and changes of these levels of aggregate output between the above mentioned countries in terms of differences in factors input and levels of technological knowledge for the period 1963 1988 sources of economic growth in each country are also examined on an annual and average annual basis th conclusion is that technological knowledge differences between countries hold a central role in explaining output differences between them a slight overtake of the technological lead is observed in comparing sweden and norway between 1977 and 1985 when a recovery by sweden begining in 1986 is detected a certain part of the output differences between the us and west germany is explaining by the differences in technology between these two countries however capital intensity in the us is found to be almost double in 1988 and this accounts fo

the existence of equilibrium in discontinuous economic games i theory the article presents information about the existence of equilibrium in discontinuous economic games in this paper and its sequel presents study the existence of nash equilibrium in games where agents payoff functions are discontinuous the enquiry is motivated by a number of recent studies that have uncovered serious existence problems in seemingly innocuous economic games in the sequel to this paper authors have explained the utility function in the economic games referred to earlier are neither continuous nor quasi concave however they demonstrate that the payoff functions in mildly modified versions of these constructs exhibit two weaker forms of continuity which together with the requirement of quasi concavity suffice for the existence of an equilibrium from this one may conclude that at least in the modified versions of these models discontinuities in the payoff functions are not the real source of the problem rather it is the failure of the payoff functions to the quasi concave which is responsible for the non existence of equilibrium these observations bear on the existence of nash equilibrium in pure strategies

causes of the current stagflation since 1975 labour slack has been unusually high in the oecd countries and yet inflation has not diminished the less favourable mix of unemployment and rate of change of inflation which we call stagflation is explained by a fall in the feasible rate of growth of real wages unmatched by a reduction in the constant term in phillips curve to investigate this mechanism conventional wage and price equations are estimated for 19 countries and then used for simulation stagflation has been caused in roughly equal amounts by rising relative import prices and by the fall in the rate of productivity growth in the basic model the phillips curve is assumed not to adapt to falls in feasible real wage growth but in a final section an adaptive wage equation is estimated which confirms that the process of adaptation is slow

education language and youth entrepreneurship in chad this study aims to assess the effect of education language arabic or french on the probability of being self employed in chad mainly we make use of a recursive bivariate probit model and matching techniques to assess the effect as well as to remedy to the endogeneity problem overall the analysis suggests that youths with arabic language education are more likely to be self employed however most of them specialise in modest informal micro enterprises these results can help to shed light on the education language implications and then can help policymakers to design appropriate policies to foster youth entrepreneurship in chad

pure strategy nash equilibria of non zero sum two person games non convex case abstract consider the class of the non zero sum two person games on the unit square if the payoff functions are continuous and satisfy a new and weaker condition than the usual conditions of concavity or quasiconcavity we prove that these games possess a pure strategy nash equilibrium

the boundaries of the firm revisited why do firms exist what is their function and what determines their scope these remain the central questions in the economics of organization they are also central questions for business executives and corporate strategists the worldwide volume of corporate mergers and acquisitions exceeded 1 6 trillion in 1997 it is hard to imagine that so much time effort and investment bankers fees would be spent on adjusting firm boundaries unless there was some underlying economic gain indeed the exceptional levels of merger and acquisition activity over the past two decades are a strong indication that economically significant forces do determine organizational boundaries the study of firm boundaries originated with the famous essay by coase 1937 who raised the question of why we observe so much economic activity inside formal organizations if as economists commonly argue markets are such powerful and effective mechanisms for allocating scarce resources coase s answer was in terms of the costs of transacting in a world of imperfect information when the transaction costs of market exchange are high it may be less costly to coordinate production through a formal organization than through a market in large part thanks to the work of williamson 1975 1985 recent decades have seen a resurgence of interest in coase s fundamental insight that firm boundaries can be explained by efficiency considerations our understanding of firm boundaries has been sharpened by identifying more precisely the nature and sources of transaction costs in different circumstances in the process the focus of

the effects of human capital interventions on entrepreneurial performance in industrialized countries this paper provides a systematic review of studies on the effects of human capital interventions on entrepreneurial performance in industrialized countries we identify 21 experimental and quasi experimental studies published before september 2018 these studies examine the effects of business training formal education and entrepreneurship education their performance outcomes include firm profits firm size and entrepreneurial earnings the main finding across these studies is that these interventions do not have statistically significant effects formal education is the only exception showing positive effects on firm profits and entrepreneurial earnings yet these effects are small in magnitude evidence is inconclusive regarding effect duration these findings stand in stark contrast to correlational studies which tend to find large positive correlations between human capital interventions and entrepreneurial performance we therefore conclude that correlational studies tend to overestimate the benefits of human capital interventions moreover our estimates show that the interventions are associated with moderately low additionality

modeling production for general equilibrium analysis the purpose of this paper is to present econometric models of producer behavior suitable for incorporation into a general equilibrium model implementation of these models requires a time series of inter industry transactions tables second implementation requires methods for estimation of parameters in systems of nonlinear simultaneous equations finally the economic theory of producer behavior implies equality and inequality restrictions on the parameters that must be incorporated into the estimation we discuss an empirical application to modeling producer behavior in thirty six industrial sectors of the u s economy

active labor market policy evaluations a meta analysis this article presents a meta analysis of recent microeconometric evaluations of active labour market policies we categorise 199 programme impacts from 97 studies conducted between 1995 and 2007 job search assistance programmes yield relatively favourable programme impacts whereas public sector employment programmes are less effective training programmes are associated with positive medium term impacts although in the short term they often appear ineffective we also find that the outcome variable used to measure programme impact matters but neither the publication status of a study nor the use of a randomised design is related to the sign or significance of the programme estimate

behavioural additionality of r d subsidies a learning perspective the use of r d grants as a policy instrument has been motivated by economic arguments of market failure neo classical econometric studies have analysed the additionality of one euro of subsidies on both the investments of companies in the r d process and the output of that r d process more recently behavioural additionality has been launched as a third form of additionality in contrast to input and output additionality behavioural additionality is related to changes in the processes that take place within the firm in this paper we analyse the determinants of the behavioural additionality of r d grants to explain the mechanism through which behavioural additionality is obtained we use organizational learning theory as a guide to formulate our hypotheses hypotheses are tested using a telephone survey of 192 recipients of r d grants provided by the iwt in flanders in 2001 2004 matched to a sample of 84 firms that undertake innovation activities but which had never had a grant bid accepted we find that congenital learning and interorganizational learning lead to increased behavioural additionality however these learning effects decrease with the number of subsidized projects that are undertaken by the company

examining the formation of human capital in entrepreneurship a meta analysis of entrepreneurship education outcomes abstract effective human capital formation through the medium of entrepreneurship education and training eet is of increasing concern for governments as eet is growing rapidly across the world unfortunately there is a lack of consistent evidence showing that eet helps to create more or better entrepreneurs we undertake the first quantitative review of the literature and in the context of human capital theory find that there is indeed support for the value of eet based on 42 independent samples n 16 657 we find a significant relationship between eet and entrepreneurship related human capital assets r w 217 and entrepreneurship outcomes r w 159 the relationship between eet and entrepreneurship outcomes is stronger for academic focused eet interventions r w 238 than for training focused eet interventions r w 151 we find evidence of heterogeneity in many of our correlations and recommend that future studies examine potential moderators to more clearly delineate eet effect sizes we also find a number of methodological weaknesses among the studies analyzed and that those studies with lower methodological rigor are overstating the effect of eet recommendations to improve the quality of future work in the field are provided

the impact of an adult education voucher program evidence from a randomized field experiment abstract lifelong learning is often promoted in aging societies but little is known about its returns or governments ability to advance it this paper evaluates the effects of a large scale randomized field experiment issuing vouchers for adult education in switzerland we find no significant average effects of the voucher program on earnings employment and subsequent education 1 year after treatment but effects are heterogeneous low educated individuals are most likely to profit from adult education but least likely to use the voucher in addition the public voucher program appears to crowd out firm financed training the findings cast doubt on the effectiveness of untargeted voucher programs in promoting labor market outcomes through adult education
