price distortions financing constraints and second best investment rules in the transportation industries abstract this paper analyzes the second best pricing and investment rules to be followed in the transportation industries in the presence of intermodal competition exogenous price distortions and financing constraints using both theoretical and simulation analysis it shows that price distortions and financing constraints in one mode will not only affect the investment rules in that mode but will also affect the pricing rules and investment decisions in all other modes while the theoretical discussion indicates that the second best pricing and investment rules are quite complex the simulation analysis indicates that the benefit function is relatively flat suggesting that the costs of using simpler first best rules may be relatively small

government r d subsidies as a signal for private investors abstract government subsidies for r d are intended to promote projects with high returns to society but too little private returns to be beneficial for private investors this may be caused by spillovers or a low appropriability rate apart from the direct funding of these projects government grants may serve as a signal for good investments for private investors we use a simple signaling model with different types of r d projects to capture this phenomenon the agency has a preference for basic research projects as they promise high expected social returns while banks prefer applied research projects with high private returns in a setup where the subsidy can only be used to distinguish between basic and applied research projects government agency s signal is not very helpful for banks however if the subsidy is accompanied by a quality signal it can lead to increased or better selected private investments

public subsidies and the employment growth of high tech start ups assessing the impact of selective and automatic support schemes the aim of this article is to assess the impact of public subsidies on the employment growth of new technology based firms ntbfs contingent on i the type of policy scheme either selective or automatic and ii the age of the firms at the time of receipt of the subsidy for this purpose we analyze a sample composed of 536 italian independent ntbfs observed during a 10 year period 1994 2003 we estimate augmented gibrat law type dynamic panel data models using different techniques aimed at controlling for the potentially endogenous nature of public financing namely the generalized method of moments system fixed effect instrumental variable and inverse probability treatment weights estimators the results of the estimates show that selective support schemes had a larger impact on employment growth than automatic ones but only if they were awarded in the very early period of the recipient firms lives however selective subsidies awarded to young ntbfs are rare in italy calling into question the capability of the italian industrial policy to sustain the growth of the high tech entrepreneurial sector

spatial structure of agricultural production in china the spatial structure of county level agricultural production in china in 1999 is analysed a convenient simple method that corrects for both spatial autocorrelation and spatial heterogeneity in the input output relationships using spatial lag models and an allowance for the response coefficients to vary across relatively homogeneous regions are described empirical results suggest an abundant labour supply and extensive use of agricultural machinery reflected in its declining price although mechanization is relatively new machines have replaced fertilizer in agricultural production in the north northeast northwest and east regions while irrigation and fertilizer are the significantly important inputs in the central and southwest regions

interorganizational alliances and the performance of firms a study of growth and innovation rates in a high technology industry this paper investigates the relationship between intercorporate technology alliances and firm performance it argues that alliances are access relationships and therefore that the advantages which a focal firm derives from a portfolio of strategic coalitions depend upon the resource profiles of its alliance partners in particular large firms and those that possess leading edge technological resources are posited to be the most valuable associates the paper also argues that alliances are both pathways for the exchange of resources and signals that convey social status and recognition particularly when one of the firms in an alliance is a young or small organization or more generally an organization of equivocal quality alliances can act as endorsements they build public confidence in the value of an organization s products and services and thereby facilitate the firm s efforts to attract customers and other corporate partners the findings from models of sales growth and innovation rates in a large sample of semiconductor producers confirm that organizations with large and innovative alliance partners perform better than otherwise comparable firms that lack such partners consistent with the status transfer arguments the findings also demonstrate that young and small firms benefit more from large and innovative strategic alliance partners than do old and large organizations copyright 2000 john wiley sons ltd

enterprise restructuring and embeddedness a policy and systems perspective this paper presents a dynamic analysis of technological and industrial policies directed to business sector restructuring in increasingly knowledge based economies it simultaneously considers policies which are aimed at promoting restructuring directly and policies aimed at influencing the facilitating structure of largely non business institutions and organizations this paper also offers an explicit analysis of the changing portfolio of policies recognizing the complementarity of both incentives and institutional development and the likelihood of having to adopt under a broad set of circumstances a changing portfolio of horizontal and target incentives policies programs copyright 2000 by oxford university press

spatially correlated exit strategies in the baking industry this article uses a unique data set to analyse economic factors that explain firm exit and the interrelation across firms in space when exiting results show the effectiveness of modelling spatial correlation in a logit exit model indeed in our application reliable statistical results could only be drawn from our data when including spatial correlation in the model

the relationship between firm growth size and age estimates for 100 manufacturing industries this study uses a sample of all firms operating in 100 manufacturing industries to examine some aspects of firm dynamics it finds that firm growth the variability of firm growth and the probability that a firm will fail decrease with firm age it also finds that firm growth decreases at a diminishing rate with firm size even after controlling for the exit of slow growing firms from the sample gibrat s law therefore fails although the severity of the failure decreases with firm size copyright 1987 by blackwell publishing ltd

blue carbon knowledge gaps critical issues and novel approaches blue carbon the carbon stored and sequestered in mangrove forests seagrass meadows and tidal salt marshes is considered a cost effective means to achieve positive climate change mitigation and adaptation outcomes blue carbon is therefore of considerable interest to the scientific and policy communities and is frequently discussed in relation to carbon markets and climate finance opportunities this paper identifies peer reviewed and gray literature documents that discuss blue carbon in the context of finance and market mechanisms the document set is analyzed both quantitatively and qualitatively and the principal scientific economic regulatory social and management issues that emerge are discussed the study reveals that 1 the blue carbon literature is dominated by technical and policy commentary with a dearth of research into practical social considerations and a stark absence of private sector perspectives 2 there is confusion over the nature and role of important concepts including private and public sector finance and instruments and 3 understanding of the important issues of investment priorities and risk considerations is also limited this paper therefore identifies gaps in the blue carbon literature clarifies critical concepts and issues and proposes novel pathways for blue carbon research and project development

on calculating the optimal commodity tax rate an alternative to social welfare maximisation abstract this paper proposes an alternative to the traditional social welfare function maximisation procedure for the calculation of optimal commodity tax rates the proposed procedure uses a loss minimisation strategy based on an explicit model of redistribution illustrative calculations on indian budget data show the potential usefulness of the procedure

optimally uniform commodity taxes and non linear engel curves a generalisation of the linear case abstract a sufficient condition for optimally uniform commodity taxes is derived in the more realistic non linear engel curve case and in a form that allows easy checking from the various parameter estimates this general condition is shown to yield certain well known sufficient conditions as special cases

the relationship between r d collaboration subsidies and r d performance empirical evidence from finland and germany this study focuses on the impact of innovation policies and r d collaboration in germany and finland we consider collaboration and subsidies as heterogeneous treatments and perform an econometric matching to analyze r d and patent activity at the firm level in general we find that collaboration has positive effects in germany subsidies for individual research do neither exhibit a significant impact on r d nor on patenting but the innovative performance could be improved by additional incentives for collaboration for finnish companies public funding is an important source of finance for r d without subsidies recipients would show less r d and patenting activity whilst those firms not receiving subsidies would perform significantly better if they were publicly funded copyright 2007 john wiley sons ltd

capital market imperfections high tech investment and new equity financing highly variable returns asymmetric information and a lack of collateral should cause small high tech firms to have poor access to debt new equity financing has several advantages over debt but may be costly compared to internal finance we examine an unbalanced panel of over 2 400 publicly traded us high tech companies over the period 1981 98 most small high tech firms obtain little debt financing new equity financing in the form of the initial public offering is very important and permits a major increase in firm size after going public comparatively few firms make heavy use of external finacing

public policy measures to support new technology based firms in the european union abstract this paper provides a review of public policy measures implemented in eu countries to support new technology based firms ntbfs during the 1980s and early 1990s it identifies five policy areas and provides a synthesis of the policy developments during this period and an assessment of their effectiveness the policy areas examined are science parks the supply of phds in science and technology the relationships between ntbfs and universities research institutions direct financial support to ntbfs from national governments and the impact of technological advisory services on ntbfs although considered independently these issues are clearly part of an interdependent system of policies and we conclude with an overview of the whole policy area together with our personal recommendations for its improvement

determinants of food consumption in rural sierra leone abstract this paper reports the application of a quadratic expenditure system with demographic variables to the household consumption leisure choice component of a household firm model a system of seven commodities is estimated including five foods non food and leisure appropriate for such a level of disaggregation a demand system is used the quadratic expenditure system which allows for a flexible relationship between full income and commodity expenditures without sacrificing parsimony in parameters demographic data on households are explicitly incorporated into the model allowing for a richer specification than can be achieved by using per capita variables the data are from a cross section survey of households in rural sierra leone price variation exists by region permitting estimation of a complete demand system engel curves are found to be significantly non linear with marginal expenditure on rice the major staple declining with higher income most foods are found to be reasonably price responsive with sizeable own price substitution effects declining with higher income aggregate labor supply is found to be price inelastic

when bureaucrats meet entrepreneurs the design of effective public venture capital programmes recently public efforts to finance small high technology firms have proliferated we review the motivations for these efforts and make some preliminary observations about their design we explore the underlying challenges that the financing of young growth firms poses the ways that specialised financial intermediaries address them and the rationales for public efforts to finance these companies the final section makes a set of observations about the ways in which the structure of these efforts can most effectively complement private sector activity a frequent fault in programme design is the presumption that technological criteria can be divorced from business considerations when evaluating firms the federal government has played an active role in financing new firms particularly in high technology industries since the soviet union s launch of the sputnik satellite in recent years european and asian nations and many us states have adopted similar initiatives while these programmes precise structures have differed the efforts have been predicated on two shared assumptions i that the private sector provides insufficient capital to new firms and ii that the government either can identify investments which will ultimately yield high social and or private returns or can encourage financial intermediaries to do so in contrast to other government interventions designed to boost economic growth such as privatisation programmes these claims have received little scrutiny by economists the neglect of these questions is unfortunate while the sums of money involved are modest relative to public expenditures on defence procurement or retiree benefits these programmes are very substantial when compared to contemporaneous private investments in new firms government programmes in this arena have been divided between those efforts that directly fund entrepreneurial firms and those that encourage or subsidise the development of outside investors in this paper i will focus on public venture capital initiatives programmes that make equity or equity like investments in young firms or encourage other intermediaries to make such investments in some such programmes such as the advanced technology program and the small business innovation research programmes discussed below the funds are provided as a contract or outright grant while these efforts have proliferated a consensus as to how to structure these programmes remains elusive while the design of regulatory agencies has been extensively studied from a theoretical and empirical perspective little work has

a dynamic analysis of expenditure patterns in rural india abstract recent generalisations of the linear expenditure system have concentrated on its restrictive assumption of separable preferences but underplayed its equally restrictive assumption of linearity in income i e constant marginal budget shares this reflects the data base which has usually been long time series of disaggregated consumer expenditure data such generalisations are inappropriated for developing countries which rely on highly aggregated commodity expenditure data from budget surveys with more variation in income responses is introduced variation in prices a general procedure for non linearising income but rather limited applied to some recent les generalisations to generate still further geenralisations and then used to analyse rural india s expenditure behaviour the results decisively support the suggested generalisation and also provide evidence in favour of dynamic behaviour and habit persistence on budget data

sensitivity of optimal commodity tax rates to alternative demand functional forms an econometric case study of india this study investigates on a nine commodity disaggregation of indian budget data nss 28th round the sensitivity of optimal commodity tax rates to alternative demand systems les and rnlps optimality is used here in the very special sense of being conditional on observed expenditure and fixed consumer prices the alternative sets of tax rates agree at low levels of inequality aversion but disagree widely at rawlsian levels les is heavily rejected in favour of its one parameter generalisation rnlps the results suggest that les price elasticities should not be used in optimal tax calculations the optimal tax rates imply only a modest redistribution

demographic effects in demand analysis estimation of the quadratic expenditure system using microdata the purpose of this paper is to estimate a complete theoretically plausible system of demand equations on microdata using the rich detail of these data to investigate the impact of demographic variables on demand behavior the system which we estimate is the quadratic expenditure system qes introduced by howe pollak and wales we evaluate four methods for incorporating demographic variables into the demand system three of these procedures imply parameter restrictions while the fourth does not tests on the restrictions imply that for our data unrestricted estimation yields significantly greater explanatory power

cost functions under production uncertainty we characterize the cost functions which would be consistent with expected utility maximization when production is uncertain it is not generally possible assuming risk aversion to use only expected output as the constraint in a cost minimization problem in some leading cases cost functions consistent with expected utility maximization are particularly useful because they are devoid of risk preferences

the examination of pecan price differences using spatial correlation estimation a spatial analysis is used to model factors that explain the price received by pecan growers besides the statistical aspect of the study focussing on spatial autoregressive residuals the economic analysis of the paper identifies linkages between the price for in shell pecans received by growers and the characteristics of the orchard production costs and resources and the orchard location

is there curvature in the slutsky matrix d o the poor substitute among commodities more flexibly than the rich when relative prices change even when compensated for the income effects of the price changes is it necessary to add a third dimension to the slutsky substitution matrix to identify household income in short do the terms of the slutsky elasticity matrix curve smoothly from poor households to rich households in such a way that equation 1 is meaningful

who participates in r d subsidy programs the case of spanish manufacturing firms abstract empirical evidence on the effectiveness of r d subsidies to firms has produced mixed results so far one possible explanation is that firms and project selection rules may be quite heterogeneous both across agencies and across industries leading to different outcomes in terms of the induced additional private effort here we focus on the participation stage using a sample of spanish firms we test for differences across agencies and industries our results suggest that firms in the same industry face different hurdles to participate in different agencies programs that participation patterns may reflect a combination of agency goals and that patterns differ across high tech and low tech industries

structural breaks in consumption patterns india 1952 1991 this study improves upon the econometric modelling for testing and incorporating structural breaks for a study on indian consumption patterns covering a period of four decades and also explores the causes of such breaks the tests for structural breaks in consumption patterns indicate multiple break points which are not uniform across the population groups and also across commodity groups further the results indicate for the first time that the breaks could often be induced by the changes in the data collection methodology of the survey and not due to changes in consumer behaviour alone apart from this there is a shift in the consumption pattern during the mid 1980s in both the rural and the urban sectors for the lowest expenditure class the shift is away from food items with the rural sector showing a change in the price response and the urban sector showing a change in the total expenditure coefficient for the middle and the upper expenditure classes the shifts are not only from the food items to

in search of complementary assets the determinants of alliance formation of high tech start ups abstract why do new technology based firms ntbfs cooperate starting from teece s teece d j 1986 profiting from technological innovation implications for integration collaboration licensing and public policy research policy 15 285 305 conceptual framework and taking advantage of subsequent literature on alliance formation in the resource and competence based tradition and in the social structure perspective we derive an empirical model that aims at highlighting the inducements and obstacles that these firms face in alliance formation according to firm specific characteristics and the nature of the alliance in particular a distinction is made between exploitative commercial alliances and explorative technological alliances the econometric estimates based on a large sample of italian young high tech firms that are observed from 1994 to 2003 provide strong evidence supporting two key intuitions of teece s work first the combination of specialized complementary assets appears to be a key driver of the formation of exploitative commercial alliances by ntbfs more specifically patent holding affects positively the likelihood to establish commercial alliances but this propensity is found to rapidly decrease with firm size suggesting that as long as ntbfs become larger and possess specialized commercial assets their urge for commercial alliances diminishes second following the parallelism set forth by teece between search for alliance partners and access to external financing the analysis indicates that potentially beneficial alliances may not take place because of the high transaction costs faced by smaller ntbfs in this respect our results clearly support the view that sponsor institutions as public research organizations venture and corporate venture capitalists may sensibly reduce these costs and that their role crucially depends on both the identity of the sponsor and the type of alliance

is subsidizing entry an optimal policy public subsidies in support of new firm foundation are among the most frequently used instruments of industrial policy in the euro zone this paper analyses their effectiveness and efficiency vis a vis some features of the overall process of industry dynamics in italian manufacturing to this end the survival and growth patterns of new small firms are investigated using a unique dataset on electrical and electronic engineering in italy as regards survival our results confirm the findings of other studies namely that the hazard rates are particularly high in the early stages of firm s life cycle as far as growth is concerned the study s main finding is that gibrat s law fails to hold in the years immediately following start up when smaller firms must rush in order to achieve a size large enough to enhance their likelihood of survival conversely in later stages of firm s life cycle the law cannot be rejected these results radically question the use of subsidies as an optimal policy for the support of new entries since the subsidy brings about a major bias in the process of market selection including substitution and deadweight effects and hampers the post entry scale adjustment of newborn firms

multistage selection and the financing of new ventures using a random sample of 221 new swedish ventures initiated in 1998 we examine why some new ventures are more likely than others to successfully be awarded capital from external sources we examine venture financing as a staged selection process in which two sequential selection events systematically winnow the population of ventures and influence which ventures receive financing for a venture to receive external financing its founders must first select it as a candidate for external funding and then a financier must fund it we find evidence that founders select ventures as candidates for external finance based on their perceptions of market competition market growth and employment growth while financiers base funding decisions on objective verifiable indicators of venture development such as the completion of organizing activities marketing activities and the level of sales of the venture our findings have implications for venture financing and evolutionary theories of social processes

estimation of ses for heteroscedastic and cross sectionally correlated data this study develops se estimators for heteroscedastic and cross sectionally correlated data the new estimators are a cross sectional version of the white and domowitz 1984 and newey and west 1987 estimators and therefore consistent in the presence of heteroscedasticity and cross correlation of unknown form unlike the estimators in the literature these estimators can control for cross correlation even for single period cross sectional data

venture capitalists and cooperative start up commercialization strategy this paper examines the possible impact of venture capital vc backing on the commercialization direction of technology based start ups by asking to what extent if at all do vc funded start ups engage in cooperative commercialization strategies strategic alliances or technology licensing or both relative to a comparable set of start ups and with what consequences to address these questions i assemble a novel data set that matches firms receiving a federal research and development subsidy through the u s small business innovative research program to vc funded firms by observable characteristics in five technology intensive industries these data allow decoupling of cooperative activity resulting from start up development via the passage of calendar time from that due to association with vcs an analysis of the 696 start ups in the sample split by an external funding source suggests substantial boosts in both cooperative activity associated with vc backed firms and in the likelihood of an initial public offering
