appropriate business strategy for leaders and laggards we develop a series of hypotheses that predict that the appropriateness of different business strategies is conditional on the firm s relative performance or distance to the industry frontier we use data on three 2 digit high tech manufacturing industries in the united states over the period 1972 1999 and apply semi parametric quantile regressions to investigate the contribution of firm behavior to market value at various points of the conditional distribution of tobin s q among our results we observe that innovative activity measured in terms of r d expenditure or patents has a strong positive association with market value at the upper quantiles corresponding to the leader firms whereas the innovative efforts of laggard firms are valued significantly less laggard firms we suggest should instead achieve productivity growth through efficient exploitation of existing technologies and imitation of industry leaders employment growth in leader firms is encouraged whereas growth of backward firms is not as well received on the stock market

market share market value and innovation in a panel of british manufacturing firms this paper examines the empirical relationship between technological innovations market share and stock market value new developments in the estimation of dynamic count data models are used to control for unobserved firm specific heterogeneity we find a robust and positive effect of market share on observable headcounts of innovations and patents although increased product market competition in the industry tends to stimulate innovative activity furthermore the impact of innovation on market value is larger for firms with higher market shares we argue that our results are consistent with models where high market share firms have incentives to pre emptively innovate

product innovation and firm growth evidence from the integrated circuit industry applied research on growth and innovation seems to suggest that successful innovations do not significantly enhance firm growth this paper tests the hypothesis that the level of observation at which applied research is typically conducted hampers identification of a significant association between innovation and sales growth rates exploiting a unique data set we find that product innovations commercialized in the immediate past positively affect the corporate revenue streams of semiconductor companies

existence of equilibrium in single and double private value auctions we show existence of equilibria in distributional strategies for a wide class of private value auctions including the first general existence result for double auctions the set of equilibria is invariant to the tie breaking rule the model incorporates multiple unit demands all standard pricing rules reserve prices entry costs and stochastic demand and supply valuations can be correlated and asymmetrically distributed for double auctions we show further that at least one equilibrium involves a positive volume of trade the existence proof establishes new connections among existence techniques for discontinuous bayesian games

from fossil fuels to renewables the role of electricity storage abstract electricity storage represents a solution to curb carbon emissions by enabling more use of intermittent renewable energy our goal is to empirically analyze the determinants of innovation in electricity storage and its role in fostering technological innovations in renewable and conventional electricity generation using a global firm level data set of electricity patents from 1963 to 2011 we find that better electricity storage promotes innovation not only in renewable energy but also in conventional technologies specifically our estimates show that an additional storage patent increases the probability to apply for patents in renewable energy and efficiency improving fossil fuel technologies two years from now by 1 09 and 0 65 respectively this implies that improved electricity storage technologies can boost the energy efficiency of conventional fossil fuel fired power plants as well as increase the use of renewable electricity thus the ability of electricity storage to curb carbon emissions depends on the competitiveness of renewable energy against conventional electricity generation and conventional power generation mix as storage increases fossil fuel efficiency and reduces ramping costs

innovation and communication signalling with partial disclosure this paper introduces a model of feedback effect equilibrium i e equilibria in which an asymmetrically informed agent is motivated to communicate its privately known attribute but can do so only through channels or signals which convey directly useful information to competing agents this revelation to the competition serves to reduce the value of the private information held by the first agent models of this kind are of obvious relevance to realistic theories of product or financial market disclosure policies of firms patenting and a host of related behavioural and regulatory issues this model is developed in the context of a set of firms engaged in research and development rivalry in which the value of privately held and disclosed information arises from its implications for the likelihood and timing of productive innovation

technological leadership and persistence of monopoly under endogenous entry static versus dynamic analysis abstract we build a dynamic oligopoly model with endogenous entry in which a particular firm leader invests in an innovation process facing the subsequent entry of other firms followers we identify conditions that make it optimal for the leader in the initial oligopoly situation to undertake pre emptive r d investment strategic predation eventually resulting in the elimination of all followers compared to a static model the dynamic one provides new insights into the leader s intertemporal investment choice its optimal decision making and the dynamics of the market structure over time we also contrast the leader s investment decisions with those of the social planner

how do competitive pressures affect incentives to innovate when there is a market for inventions competition and intellectual property ip protections are complements in stimulating innovation when ip is appropriable a market for inventions forms and competitive pressures increase incentives to innovate competition among producers the demand side of the market for inventions and competition among inventors the supply side of the market for inventions create incentives to innovate when ip is not fully appropriable markets for inventions are limited and competitive pressures can decrease incentives to innovate firms vertically integrate r d and production and share technology to appropriate the returns to ip this implies that antitrust policy and ip protections are complements

equity valuation under bull and bear market regimes in south east asia firms a switching regression approach a switching regression approach is used to analyse the market equity value of firms in the three south east asia countries with a comparison to japan two regimes are used to optimally sort the firms in a given country based on a switching function using profit rate net income to book equity as its variable the regimes are identified as a bear security market or a bull security market depending on the value of the profit rate two financial ratios are used in the regime regressions it was found that the optimum scaled switch point separating the bulls from the bears for the countries was a positive profit rate ranging between 6 and 24 the notion that a zero or negative profit rate identifies a bear market is not supported in general the results across countries and for the long term debt ratio were quite consistent the post asian financial crisis of 1997 had a depressing effect on firm market equity values regardless of the market type and the country the bulls and the bears are not cousins whe

cross sectional heterogeneity and the persistence of aggregate fluctuations abstract the microevidence indicates that small firms grow faster than big firms i argue that this relationship between the expected growth rate of a firm and its size may provide a microfoundation for the well known high degree of persistence of shocks to aggregate output the logic goes as follows almost any shock tends to temporarily alter firms incentive to invest in growth thereby leading to a reallocation of firms across size categories if small firms grow faster than big ones the impact effect of the shock on aggregate output is gradually absorbed but as fast growing small firms become big and start to grow at the lower rate of big firms the rate at which the shock is absorbed decreases over the adjustment path as a result shocks are absorbed yet at a very low decreasing rate which induces long memory in aggregate output i argue that this transmission mechanism may reconcile the microevidence with the observed degree of aggregate persistence it requires changes in neither the number of firms in the market nor the rate of technological progress it is merely the result of the cross sectional heterogeneity that we observe in real economies

racing with uncertainty and strategic interaction between competitors as the race unfolds most of the existing literature examines one or other of these features but not the two combined our aim is to see how the efforts of competitors in a race vary with the intensity of rivalry between them in our principal model whch is of a one dimensional race it is shown that the leader in the race makes greater efforts than the follower and efforts increase as the gap between competitors decreases under certain conditions the same results hold in our second related model which is of a two dimensional race

the evolving impact of combinatorial opportunities and exhaustion on innovation by business groups as market development increases the case of taiwan business groups are key sources of innovation in emerging market economies but we understand little about why innovativeness differs across groups and over time variation in the density of intragroup buyer supplier ties which are common structural linkages among group affiliates can help explain both cross sectional and temporal heterogeneity of group innovativeness we argue that greater buyer supplier density within a group initially creates combinatorial opportunities that contribute to group innovativeness but ultimately generates combinatorial exhaustion that constrains innovation combinatorial exhaustion will set in at lower levels of density as the market environment becomes more developed because the opportunity costs of local search increase the research introduces a dynamic argument to studies of business group innovation this paper was accepted by bruno cassiman business strategy

estimating the innovator s dilemma structural analysis of creative destruction in the hard disk drive industry 1981 1998 this paper studies strategic industry dynamics of creative destruction in which firms and technologies experience turnover theories predict that cannibalization between existing and new products delays incumbents innovation whereas preemptive motives accelerate it incumbents cost dis advantage relative to that of entrants would further reinforce these tendencies to empirically assess these three forces i estimate a dynamic oligopoly model using a unique panel data set of hard disk drive manufacturers the results suggest that despite strong preemptive motives and a substantial cost advantage over entrants cannibalization makes incumbents reluctant to innovate which can explain at least 57 percent of the incumbent entrant innovation gap

a model of the evolution of duopoly does the asymmetry between firms tend to increase or decrease this paper is an attempt to identify some of the factors that affect the evolution of market structure in a model of dynamic competition between two firms the stochastic evolution of the state of competition depends on the respective effort rates of the firms the question is whether the current leader works harder than the laggard does the gap between firms tend to increase or decrease we show that several effects are at work the state tends to evolve in the direction where joint payoffs are greater since joint payoffs are related to joint product market profits less joint effort costs there are two classes of effect the joint profit effect and various joint cost effects the latter result in part from the pattern of profits and in part from endpoint effects that give relief from efforts asymptotic expansions illuminate these influences moreover we show by numerical simulation that there is another kind of joint cost effect the pattern of joint effort costs can influence the pattern of evolution of market structure and the evolution of the pattern of market structure can influence the pattern of efforts in a mutually self reinforcing manner in particular there may be equilibria in which this last effect means that the laggard works harder than the leader even though all the other effects work in favour of the leader

an empirical test of the asymmetric models on innovative activity who invests more into r d the incumbent or the challenger the theoretical discussion concerning the question whether the incumbent or the potential entrant invests more into r d has attracted considerable interest this paper reports the results of an empirical study on this question using data of about 3500 german firms over the years 1992 to 1995 the survey explicitly asks the firms for their motives to undertake innovative activity it is thus possible to take account of intended not just completed market entry it turns out that the challenger invests more into r d in order to enter a new market than the incumbent thus the patent racing model by reinganum and others seems to characterize innovative activity more accurately than the competing auction model of gilbert and newbery we use a heteroscedastic tobit as well as a tobit model with selectivity in order to deal with the econometric problems of double censoring

the size distribution of innovating firms in the uk 1945 1983 a survey of 4 378 significant innovations shows that firms with fewer than 1 000 employees commercialized a much larger share than is indicated by their share of r and d expenditures innovations per employee have been consistently above average in firms with more than 10 000 employees and have become so in firms with fewer than 1 000 intersectoral variation in the size distribution of innovating firms can be explained as a function of r and d based technological opportunities and of technological ease of entry by user firms with principal activities outside the sector copyright 1987 by blackwell publishing ltd

co determination and innovation this paper examines the effect of the german co determination law of 1976 mitbestg on the innovative activity of german firms co determination applies to firms with 2 000 employees or more data from 1971 1976 and 1981 1990 on 148 firms are used to compare the number of patents granted to co determined firms before and after the introduction of the law several control variables are applied and in particular in order to avoid a possible bias from specific effects of firm size we compare the co determined firms with others before and after 1976 the results do not support the view that co determination slows down technological progress and reduces innovativity

on the suboptimality of s 1 s lost sales inventory policies abstract this paper considers replenishment policies for the continuous review inventory model with poisson demand a fixed lead time on replenishment and lost sales during a stockout there is a time dependent stockholding cost and a cost per unit of sale lost but there is no or negligible cost associated with placing a replenishment order the standard policy is to specify a maximum stock level s and place a replenishment order whenever a demand occurs and is met this is commonly referred to as an s 1 s policy it is shown that there are other replenishment policies which give lower cost solutions in fact it is demonstrated that an s 1 s policy can never be optimal if s 2

competition and performance the different roles of capital and labor abstract neoclassical economists argue that competition promotes efficiency but schumpeter argues that it is monopoly rents that help entrepreneurs to invest in r d we investigate the overall effect of competition on total factor productivity growth tfp growth we use rent defined as the factor reward above its perfectly competitive value as a negative measure of competition our main finding is that performance is positively associated with rents on capital but not with rents on labor neoclassical economists and schumpeter may both be right but the mechanisms differ

product market regulation innovation and distance to frontier this article contributes to the literature on competition and innovation it tests the impact of market regulation on innovation conditional to the closeness to the technological frontier with a panel of 15 industries for 17 oecd countries over the period 1979 2003 one of the main conclusions of this literature is that of a negative impact of regulation growing in intensity with the proximity to the frontier a simple model of innovation and growth shows that one should not necessarily expect this result empirical tests on a variety of pecifications show that the impact of regulation can be positive when industries are close to the technological frontier we argue that this result is in fact line with previous evidence

tfp growth in british and german manufacturing 1950 1996 the paper considers the accuracy of traditional tfp growth estimates using an econometric methodology which takes account of scale economies fixed factors of production and adjustment costs to reveal underlying pure technological change the results suggest that these biases vary substantially over time but do not impact heavily on anglo german comparisons in both countries the early post war years are a period when adjustment costs from a rising supply price of capital goods hold down tfp growth below that which could have accrued from pure technological progress as might be expected this problem largely disappeared in the later globalization period

long run effects of public private research joint ventures the case of the danish innovation consortia support scheme subsidized research joint ventures rjvs between public research institutions and industry have become increasingly popular in europe and the us we study the long run effects of such a support scheme that has been maintained by the danish government since 1995 to cope with identification problems we apply nearest neighbor matching and conditional difference in difference estimation methods our main findings are that i program participation effects are instant for annual patent applications and last for three years ii employment effects materialize first after one year and iii there are no statistically significant effects on value added or labor productivity we further show that these overall results are primarily driven by firms that were patent active prior to joining the rjv and that there are no statistically significant effects for large firms the insignificant results we document for large firms coupled with the fact that these type of firms are over represented in many support programs including the one considered here leads us to suggest a rethinking of support policies that often aim at large firms

asymmetric industrial energy prices and international trade this paper measures the response of bilateral trade flows to differences in industrial energy prices across countries using a panel for the period 1996 2011 including 42 countries 62 sectors and covering 60 of global merchandise trade we estimate the short run effects of sector level energy price asymmetry on trade we find that changes in relative energy prices have a statistically significant but very small impact on imports on average a 10 increase in the energy price difference between two country sectors increases imports by 0 2 the impact is larger for energy intensive sectors even in these sectors however the magnitude of the effect is such that changes in energy price differences across time explain less than 0 01 of the variation in trade flows simulations based on our model predict that a 40 65 tco2 price of carbon in the eu ets would increase europe s imports from the rest of the world by less than 0 05 and decrease exports by 0 2

competitive conditions and sectors productive efficiency a conditional non parametric frontier analysis abstract the scope of this paper is to build an appropriate nonparametric frontier framework by using time dependent conditional efficiency estimators to investigate how competition and time affect the process of technological change and technological catch up our empirical analysis utilizes a sample of 462 u s 6 digit manufacturing sectors over the period 1958 2009 contrary to the existing studies we apply the probabilistic approach of efficiency measurement to evaluate the dynamic effects alongside with the effects of competition on the sectors technological change and technological catch up levels moreover we estimate the sectors idiosyncratic efficiencies which are an approximation of solow s residual representing the unexplained part of the time dependent conditional measures the empirical results shed new light on the topic and signify that the dynamic effect of competitive conditions has a nonlinear effect on the sectors estimated performance specifically we unveil a u shaped curve between market concentration and technological change implying that the sectors higher concentration levels enhance their technological change levels e g innovation capacity having however a downsize effect on their technological catch up ability moreover the relationship between the sectors market concentration and technological catch up although non linear exhibits an n shaped curve with two turning points lastly the above findings remain robust when we limit our analysis to the capital intensive sectors

a dynamic analysis of university agricultural biotechnology patent production this article examines the factors that account for agricultural biotechnology patenting success among universities using a dynamic count data model it builds a theoretical and econometric model to capture the inherently dynamic and nonlinear process of technological innovation wherein a feedback mechanism from previous success partially determines current patent counts the econometric estimates reveal the importance to agricultural biotechnology patent production of land grant infrastructure quality faculty patent oriented technology transfer offices as well as dynamic feedback effects the advent of exclusive property rights for university research specifically the bayh dole act has created the potential for major changes in the missions of u s universities especially among land grant universities lgus as well as in the overall system of technology creation and distribution in agriculture at the same time new genetic and cloning technologies along with the recently created ability to patent plants and living organisms are profoundly changing the range of agricultural technologies that are likely to be available in the united states and internationally indeed as zilberman yarkin and heiman argue these new agricultural biotechnologies ag biotech and their associated intellectual property rights appear to be creating a new paradigm a veritable revolution in the organization and interaction of university research and the agricultural sector under this new paradigm universities emphasize patenting innovations and then granting at times

corporate governance environmental regulations and technological change abstract this paper investigates the relationship between environmental regulations and innovation by focusing on the automobile industry in a cross country setting we provide empirical evidence that the presence of agency problems mitigates the negative effects of environmental regulations on overall r d activity which leads to full compensation when the degree of agency problems is sufficiently high guiding our empirical analysis we provide a general model consistent with the structure of existing ownership data specifically we model ownership structure as a combination of two extreme corporate governance types on the one extreme there are profit maximizers and on the other extreme there are managers who are only concerned with their private benefits the model leads to a simple country level ownership indicator and shows that if an economy is dominated by firms with higher agency problems then pollution tax might even increase overall r d while reducing pollution according to our estimations such an outcome is possible only for out of sample values of the ownership indicator where the degree of agency problems is extremely high

endogenous financial constraints and innovation we investigate which indicators of a firm s innovation activities are associated with financial constraints and analyze the nature and direction of causal links between innovation and financial constraints by estimating simultaneous bivariate probit models on data from the uk innovation surveys we show that among innovation inputs research and development r d activity increases the likelihood that firms face financial constraints among innovation outputs only new to market products generate financial constraints reverse effects on innovation appear limited to external r d

cournot competition and green innovation an inverted u relationship we examine the relationship between competition and innovation in an industry where production is polluting and r d aims to reduce emissions green innovation we present an n firm oligopoly where firms compete in quantities and decide their investment in green r d when environmental taxation is exogenous aggregate r d investment always increases with the number of firms in the industry next we analyse the case where the emission tax is set endogenously by a regulator committed or time consistent with the aim to maximise social welfare we show that an inverted u relationship exists between aggregate r d and industry size under reasonable conditions and is driven by the presence of r d spillovers

productivity under the 1997 2010 labour government what was the productivity record under the labour government of 1997 2010 i show that productivity growth and economic performance in general was good when the uk is compared with its main international peers only the us had stronger productivity growth and the uk did better than the us in terms of the jobs market much of this improved performance was a continuation of the pattern since 1979 which broke a century of relative decline some part of the improvement is directly linked to policies especially over human capital innovation and competition we discuss the recent productivity puzzle the disappointing productivity figures since the onset of the great recession in 2008 and argue that our conclusions are unchanged as most other oecd countries have also experienced poor measured productivity

an analysis of industry concentration in south african manufacturing 1972 2001 this article examines industry concentration for the south african manufacturing sector over the 1972 2001 period for the three digit industry classification the article notes both the high level of industry concentration in south african manufacturing and a rising trend in concentration across a wide range of industries as measured by the gini and rosenbluth coefficients the article examines the impact of concentration on investment rates using a dynamic heterogeneous panel estimation methodology we find that increased concentration unambiguously lowers investment rates

university knowledge transfer private ownership incentives and local development objectives abstract we study the impact of private ownership incentive pay and local development objectives on university licensing performance we develop and test a simple contracting model of technology licensing offices using new survey information together with panel data on u s universities for 1995 99 we find that private universities are much more likely to adopt incentive pay than public ones but that ownership does not affect licensing performance conditional on the use of incentive pay adopting incentive pay is associated with about 30 40 percent more income per license universities with strong local development objectives generate about 30 percent less income per license but are more likely to license to local in state start up companies in addition we show that government constraints on university licensing activity are costly in terms of forgone license income and the creation of start up companies these results are robust to controls for observed and unobserved heterogeneity

persistence of innovation in dutch manufacturing is it spurious this paper studies the persistence of innovation and the dynamics of innovation output in dutch manufacturing using firm data from three waves of the community innovation surveys cis pertaining to the periods 1994 1996 1996 1998 and 1998 2000 we estimate by maximum likelihood a dynamic panel data type 2 tobit model accounting for individual effects and handling the initial conditions problem we find that there is no evidence of true persistence in achieving technological product or process innovations while past shares of innovative sales condition albeit to a small extent current shares of innovative sales

on the welfare effects and political economy of competition enhancing policies we analyse the welfare effects of policies that intensify product market competition and the channels through which they operate using a circular model of horizontal product differentiation with asymmetric costs we study the effects of increased price competition on market selection among incumbent firms cost reduction effort and entry of new firms the model also generates an endogenous demand for competition enhancing or retarding policies arising from cost heterogeneity and we demonstrate the possibility of a low competition political economy trap simulations of the model illustrate that the selection effects we analyse which traditional cost benefit analysis is unlikely to capture can be large

product market competition and the financing of new ventures this paper examines the interaction between venture risk product market competition and the entrepreneur s choice between bank financing and venture capital vc financing under bank financing a debt type contract emerges as optimal which allows the entrepreneur to retain full control of the venture and thus yields strong effort incentives as long as the entrepreneur can service the debt repayment however this leads to liquidation in the case of default making the venture s success quite sensitive to exogenous even temporary shocks that may hinder debt repayment under vc financing an equity type contract emerges as optimal although it is not sensitive to exogenous shocks this contract requires the entrepreneur to share a fraction of the rents with the financier thus yielding lower effort incentives for the entrepreneur there exists a threshold level of venture risk such that bank financing is optimal if and only if venture risk is below that threshold product market competition increases the value of stronger entrepreneurial incentives and thus increases the maximum level of risk the entrepreneur is willing to take before switching from bank financing to vc financing this is a robust result that is shown to hold in various models of competition including the hotelling salop dixit stiglitz and cournot to bertrand switch this paper was accepted by lee fleming entrepreneurship and innovation

the knowledge production of r and d many studies investigate the relationship between r d expenditures as an input and patents as an intermediate product or output of a knowledge production function we suggest that the productivity of research in patent production functions has been underestimated in the literature as scholars typically use information about r d i e the sum of research expenditure and development expenditure due to data availability however in most industries only applied research will lead to patentable knowledge and development happens after the initial research phase that may have led to a patent instead of using data on r d we separate the knowledge creating process into r and d this data stems from r d surveys of belgian firms it turns out that only the r part of r d expenditure has a significant effect on patents and that development expenditure are insignificant thus previous literature relying on r d expenditure suffers from a measurement error such that the coefficient of r d is biased towards zero as r d includes a large fraction of irrelevant expenditure i e development expenditure with respect to patenting

co ownership of intellectual property exploring the value appropriation and value creation implications of co patenting with different partners combining both interview data and empirical analyses at the patent and firm levels we explore the value appropriation and value creation implications of r d collaboration resulting in the co ownership of intellectual property i e co patents we make an explicit distinction between three different types of co patenting partners intra industry partners inter industry partners and universities our findings indicate that the value appropriation challenges of ip sharing are clearly evident with intra industry co patenting where partners are more likely to encounter overlapping exploitation domains co patenting with universities is associated with higher market value since appropriation challenges are unlikely to play a role and collaboration may signal novel technological opportunities although we find some evidence that co patenting corresponds to higher patent value patents co owned with firms are significantly less likely to receive self citations indicating constraints on the future exploitation and development of co owned technologies

competition innovation and the use of innovations i examine the effect of competition on the production and use of innovations using evidence from a natural experiment of policy reform the introduction of cartel legislation in the uk in the late 1950s i compare manufacturing industries which had been collusive and were therefore affected by the policy with those that had been competitive and were not affected the intensification of competition following the abolition of cartels caused a short run decrease in innovations produced but had no significant effect in the long run in contrast innovations used increased both in the short run and in the long run

strategic r d policy this paper uses a natural extension of lee and wilde s 1980 model to show that the outcome of technological competition between firms or countries depends on the resolution of two forces the profit incentive and the competitive threat using a duopoly model of a patent race the paper illustrates that by understanding the relative strength of these two forces one can not only go a long way to understanding the outcome of these races but also obtain crucial insights into the desirability of various r d policies the particular example considered in the paper is the subsidizing of r d effort copyright 1989 by royal economic society

firm characteristics and the cyclicality of r d investments the aim of this study is to combine micro aspects of firm behavior with macro aspects of business development and identify market conditions e g price competition and firm characteristics e g type of r d partners that enable a firm to have a pro cyclical anti cyclical or non systematic r d investment behavior the empirical results confirm to large extent a series of hypotheses as to innovation relevant firm characteristics that underline the three different behavior categories and allow us to make profiles of the three types of r d behavior

the relation between price and marginal cost in u s industry an examination of data on output and labor input reveals that some u s industries have marginal cost well below price the conclusion rests on the finding that cyclical variations in labor input are small compared with variations in output in booms firms produce substantially more output and sell it for a price that exceeds the costs of the added inputs the paper documents the disparity between price and marginal cost where marginal cost is estimated from annual variations in cost it considers a variety of explanations of the findings that are consistent with competition but none is found to be completely plausible

a rose by any other name are family firms named after their founding families rewarded more for their new product introductions the authors explore the relation between the way different family firms are named and the shareholder value impact of these firms new product introductions using an event study of 1 294 product introduction announcements of 107 publicly listed u s family firms the authors find that the presence of the founding family s name as part of a family firm s name acts as a valuable firm resource increasing the abnormal stock returns surrounding the firm s new product introductions superior returns to family named firms new product introductions are partially mediated by these firms history of ethical product related behavior family named firms particularly those with corporate branding and those wherein a founding family member holds the ceo or chairman position are more likely to exhibit a history of avoiding such product related controversies as product safety issues and deceptive advertising the authors highlight the managerial and theoretical contributions of this research

corrigendum to existence of equilibrium in single and double private value auctions this is a corrigendum to theorem 15 of jackson and swinkels 2005 existence of equilibrium in single and double private value auctions econometrica 73 93 140 which proves the existence of equilibrium with positive probability of trade for private value

continuous review lost sales inventory models with poisson demand a fixed lead time and no fixed order cost abstract this paper considers continuous review lost sales inventory models with no fixed order cost and a poisson demand process there is a holding cost per unit per unit time and a lost sales cost per unit the objective is to minimise the long run total cost base stock policies are in general sub optimal under lost sales the optimal policy would have to take full account of the remaining lead times on all the orders currently outstanding and such a policy would be too complex to analyse let alone implement this paper considers policies which make use of the observation that for lost sales models base stock policies can be improved by imposing a delay between the placement of successive orders the performance of these policies is compared with that of the corresponding base stock policy and also with the policy of ordering at fixed and regular intervals of time

modified base stock policies for continuous review lost sales inventory models with poisson demand and a fixed lead time abstract this paper reconsiders the lost sales inventory system studied by hill 2007 the commonly assumed policy to apply to the system is a pure base stock policy pbsp for which the best base stock is easily found hill shows that his simple delay policy sdp and full delay policy fdp perform better the sdp is a s d policy where s is the base stock of the best pbsp and d is a common lower bound on the delay between the placement of successive replenishment orders we show by simulation that the d value suggested by johansen 2001 outperforms hill s suggestion and that the performance often can be further improved by optimizing d for the test bed investigated by hill we show that for some parameter settings an additional improvement is achieved when s and d are optimized simultaneously the policy suggested by johansen performs better than the fdp in all settings where the former policy reduces the average cost of the best pbsp by at least 1

equity compensation and the sensitivity of research and development to financial market frictions abstract when financial market frictions exist executives may have to decide which investment activities to reduce when internal funds decrease expenditures on research and development r d may be particularly vulnerable because of the long term nature of innovative activity we find that equity compensation is associated with lower levels of firm r d expenditures rewarding executives to incur more risk has little effect on r d expenditures but rewarding executives for higher returns reduces r d expenditures and makes r d expenditures more sensitive to financial market frictions in contrast cash compensation reduces the sensitivity of r d expenditures to financial market frictions

growth technological change and ict diffusion recent evidence from oecd countries in this paper we present an overview of gdp and productivity growth patterns in oecd countries over the past decade on the basis of harmonized data our evidence suggests that fast growing countries generally shared three characteristics improvements in labour utilization a generalized enhancement in human capital and rapid shifts in the composition of physical capital towards information and communication technology ict equipment particularly we show that technological change embodied in new ict capital goods has been a primary source of output and productivity growth in ict using sectors the international comparison allows relating growth patterns to institutional and policy indicators thereby offering some preliminary insights into the potential sources of growth disparities cross country evidence yields some tentative support to the idea that institutional factors affecting competition in the product market are likely to affect productivity patterns especially in a period of rapid diffusion of a general purpose technology such as ict copyright 2002 oxford university press

first to market is technological innovation in new product development profitable in health care industries abstract do innovative products incorporated advanced technologies help firms improve operating performance in this study we traced the operating performance of 168 publicly traded manufacturing firms in the usa that announced technologically innovative products in two major industries from the health care domain namely pharmaceuticals and medical instruments we employed the event study methodology and collected objective financial data from compustat we found that technologically innovative products have a statistically significant positive effect on operating performance the median abnormal increase in return on assets ranged from 2 20 to 7 07 over a four year period the median abnormal increase in return on sales ranged from 4 16 to 4 70 and the median abnormal increase in sales over assets ranged from 5 85 to 7 38

preemptive patenting and the persistence of monopoly this article takes a different tack and inquires whether institutions such as the patent system create opportunities for firms with monopoly power to maintain their monopoly power the results apply to other situations such as brand identification spatial location and capacity expansion which share the characteristic that early or preemptive actions may lower the returns to potential competitors

sectoral patterns of production and use of innovations in the uk 1945 1983 abstract based on information on more than 4000 innovations commercialised in the uk between 1945 and 1983 we analyse sectoral patterns and trends in the production and use of innovations a few core sectors chemical mechanical instruments and electronic are of major importance in the production of technology that gets used over a much wider range of sectors including those outside manufacturing similar sectoral patterns of production and use exist in the uk and usa the trend over time in the uk has been toward greater sectoral interdependence in technology and a higher share of uses outside manufacturing reflecting the growth and spread of the electronic based technological cluster any understanding of the nature determinants and dynamics of intersectoral differences in patterns of production and use of technology will require an integration into empirical and theoretical analysis of the characteristics of innovating firms

firm heterogeneity and the pattern of r d collaborations we consider an oligopoly setting in which firms form pairwise collaborative links in rd 2 some firms have more innovative capabilities than others these two situations provide clear insights about how firms heterogeneity affects both equilibrium and efficient networks we also show that the most valuable collaborative links do not always appear in equilibrium and a public policy that increases the value of the most valuable links may lead to a loss of social welfare

long run versus short run decisions r d and market structure in spanish firms abstract i present new econometric evidence on the relation between market structure and r d using data on spanish firms i adopt a different approach from previous studies by distinguishing between long run and short run decisions of firms regarding r d i assume that the long run or strategic decision is whether to conduct r d or not and the short run choice is how much to invest once the firm decides to be innovative i argue that market structure affects long run r d decisions but does not affect short run ones a heckman type selection model is used to test such a relation the results are robust to several specifications and measures of monopoly power

competitive pressure and the adoption of complementary innovations liberalization of the european automobile distribution system in 2002 limits the ability of manufacturers to impose vertical restraints leading to a substantial increase in competitive pressure among dealers we estimate an equilibrium model of profit maximization to evaluate how dealers change their innovation adoption strategies following the elimination of exclusive territories using french data we evaluate the existence of complementarities between the adoption of software applications and the scale of production firms view these innovations as substitutes and concentrate their effort in one type of software as they expand their scale of production results are robust to the existence of unobserved heterogeneity

market value r d and patents abstract a significant relationship is found between the market value of the firm and its intangible capital proxied by past r d expenditures and the number of patents based on a time series cross section analysis of data for large u s firms

product market reforms labour market institutions and unemployment we analyze the impact of product market competition on unemployment and wages and how this depends on labour market institutions we use differential changes in regulations across oecd countries over the 1980s and 1990s to identify the effects of competition we find that increased product market competition reduces unemployment and that it does so more in countries with labour market institutions that increase worker bargaining power the theoretical intuition is that both firms with market power and unions with bargaining power are constrained in their behaviour by the elasticity of demand in the product market we also find that the effect of increased competition on real wages is beneficial to workers but less so when they have high bargaining power intuitively real wages increase through a drop in the general price level but workers with bargaining power lose out somewhat from a reduction in the rents that they had previously captured

r d and credit rationing in smes we study the effects of credit rationing on research and development r d investment using survey and accounting data on a large representative sample of manufacturing small and medium sized enterprises smes our econometric model accounts for the endogeneity of our credit rationing indicator and employs an innovative theory based identification strategy we find that credit rationing has a significantly negative effect on both the probability to set up r d activities and on the level of r d spending conditioned on the r d decision but the overall estimated reduction in r d spending is largely to be associated with the first effect jel g21 d82 032 c35 i introduction long run economic growth and welfare resides on the production of new knowledge and its implementation into new or improved products or processes for this reason identification evaluation and correction of the detrimental effects of potential underinvestment in research and development r d activities have a prominent place in the policy agendas of all industrialized countries this is particularly the case in europe where since the start of the recent economic crisis the policy debate has been focused on the role of capital market imperfections as they increase the cost of r d when firms do not have sufficient internal funds to finance it the credit crunch that is the lack of availability or reduction in supply of credit to businesses from traditional financial institutions is said to reduce firms investment in innovative activities and growth prospects however despite its theoretical appeal and in contrast with the proven sensitivity of fixed capital investment to financing constraints evidence on the susceptibility of r d investment to financial frictions and in particular to credit rationing is still mixed and inconclusive three explanations have been put forward for the lack of robust evidence first it is claimed that the variety in the results reflects the contrast between theoretical explanations based on asymmetric information arguments suggesting a sensitivity of r d to financing constraints potentially higher than that of ordinary investment and the characteristics of r d as a long term investment with high adjustment costs suggesting rather the opposite 1 second existing evidence is based almost exclusively on the sensitivity of firm level r d spending to the availability of internal finance typically measured through cash flow which is however known to be problematic in its ability to proxy for financing constraints kaplan and zingales 1997 2000 third recent contributions have stressed the difficulty in identifying the role of financing constraint using standard investment models when firms have access to multiple channels for raising external financial resources and managing buffer stocks of liquidity brown martinsson and petersen 2011 in this study we use firm level data on r d investment and credit constraints to measure the detrimental effect of credit rationing on r d investment dealing with all the above specified issues first we claim that the ambiguity originated by information problems versus the nature of r d as a long term investment might be resolved if we distinguish between the probability of r d investment the r d participation decision and the size of r d investment once the decision to invest has been taken the amount of r d spending decision we therefore study the effect of credit rationing on the decision to do r d and on the amount of r d investment our hypothesis is that credit rationing displays a stronger effect on the first decision compared with the latter while this expectation might seem obvious to our knowledge econometric analyses on the topic have not yet addressed or proven the differential impact of credit rationing on the participation and amount decisions respectively

pure strategy equilibria of single and double auctions with interdependent values we prove the existence of monotonic pure strategy equilibrium for many kinds of asymmetric auctions with n bidders and unitary demands interdependent values and independent types the assumptions require monotonicity only in the own bidder s type the payments can be a function of all bids thus we provide a new equilibrium existence result for asymmetrical double auctions and a small number of bidders the generality of our setting requires the use of special tie breaking rules we present an example of a double auction with interdependent values where all equilibria are trivial that is they have zero probability of trade this is related to akerlof s market for lemmons example and to the winner s curse establishing a connection between them however we are able to provide sufficient conditions for non trivial equilibrium existence

does innovation cause stock market runups evidence from the great crash this article examines the stock market s changing valuation of corporate patentable assets between 1910 and 1939 it shows that the value of knowl edge capital increased significantly during the 1920s compared to the 1910s as investors responded to the quality of technological inventions innovation was an important driver of the late 1920s stock market runup and the great crash did not reflect a significant revaluation of knowledge capital relative to physical capital although substantial quantities of influential patents were accumulated during the post crash recovery high technology firms did not earn significant excess returns over low technology firms for most of the 1930s

corporate governance and innovation we use tobin s q models of investments to estimate the relationship between corporate governance and the level of innovative activity simple ordinary least squares ols models suggest that poor governance reduces innovative activity however ols results are sensitive to controlling for serial correlation unobserved effects or using instrumental variables to control simultaneity controlling for these effects substantially reduces or eliminates the relationship between governance and innovative activity

timing of technology adoption and product market competition abstract this paper examines how product market competition affects firms timing of adopting a new technology as well as whether the market provides sufficient adoption incentives it demonstrates that adoption dates differ not only among symmetric firms but also among markets with different market features more specifically technology adoption can occur earlier in a market with cournot competition than in a market with bertrand competition it can also occur earlier in a market in which goods are not too close substitutes therefore this paper shows that competition toughness does not always reinforce adoption incentives when goods are sufficiently differentiated adoption occurs later than is socially optimal

crude oil price uncertainty and corporate investment new global evidence abstract using a comprehensive dataset of more than 33 000 firms from 54 countries in the period 1984 2015 we show that crude oil price uncertainty negatively influences corporate investment more importantly the effect is dependent on the market and stock characteristics of the firms in addition we discover that the effect is stronger in the crude oil producers group than for crude consumers our analysis reveals that the global financial crisis and market volatility phases significantly affect this relationship our results survive a range of robustness tests

product market competition and the value of innovation evidence from us patent data this study investigates the relationship between product market competition and the market value of innovation using firm level patent data of us firms over the period 1977 2005 we find that there is an inverted u shaped relationship between competition and the value of innovation furthermore we show that there is an asymmetric causal effect of intensifying product market competition on the market value of innovation using a quasi natural experiment based on tariff cut events for us manufacturing firms between 1977 and 2006 a firm s incentive to innovate tends to get stronger in response to a tariff cut when product market competition is very mild while it tends to get weaker when very severe

does amd spur intel to innovate more we estimate an equilibrium model of dynamic oligopoly with durable goods and endogenous innovation to examine the effect of competition on innovation in the personal computer microprocessor industry firms make dynamic pricing and investment decisions while consumers make dynamic upgrade decisions anticipating product improvements and price declines consistent with schumpeter we find that the rate of innovation in product quality would be 4 2 percent higher without amd present though higher prices would reduce consumer surplus by 12 billion per year comparative statics illustrate the role of product durability and provide implications of the model for other industries

exploring the cross country gap in patenting a stochastic frontier approach abstract this paper benchmarks the patent activities of a sample of oecd countries against the world frontier and explores the sources of the cross country differences in patenting regarded as a proxy for innovation a patent production frontier is estimated for a panel of 21 oecd countries over the 1990 2002 period using stochastic frontier analysis patenting performance for each country is decomposed into basic patenting capacity and patenting efficiency the gap between europe and the world leaders in terms of basic patenting capacity remains substantial with little sign of convergence over the sample period in terms of patenting efficiency japan germany and italy have improved their relative position in recent years the gap in patenting performance between the uk and the world frontier is due to relative underperformance in both patenting capacity and efficiency in patent production institutional factors are found to be significantly associated with the patenting efficiency of an economy

sell or not sell biodiesel local competition and government measures the introduction of biofuels is one of the objectives of the european union for this reason measures to promote the production and consumption of this product have been implemented such as tax exemptions fixing a minimum amount of mixture or the introduction of public transport that consume biofuels in this paper we test different factors that can affect the introduction of biodiesel in the spanish gasoline market these factors are mainly the level of local competition technical difficulties and local government action empirical evidence shows that a higher level of competition more buses that consume biodiesel and a lower adjustment costs increase significantly the probability of sell biodiesel at service stations these results show how the promotion of competition and public procurement of vehicles can improve the commercialization of biofuels

r d determinants accounting for the differences between research and development the determinants of r d are an important topic of innovation studies the classical schumpeterian hypotheses about the influence of size and market power have been complemented with the role played by industry determinants such as demand pull technological opportunity and appropriability in determining r d investments however r d has always been considered as a whole even though research and development activities differ in many aspects we take advantage of a new panel database of innovative spanish firms pitec to distinguish between research and development efforts of firms we analyze the differentiated role played by traditional r d determinants in driving research and development results show that demand pull and appropriability have a higher effect on development while technological opportunity is more influential for research differences are statistically significant important in magnitude and robust to the use of different indicators for demand pull technological opportunity and appropriability and to several robustness checks

self confidence and personal motivation the maintenance and enhancement of self esteem has always been identified as a fundamental human impulse philosophers writers educators and of course psychologists have all emphasized the crucial role played by self image in motivation affect and social interactions the aim of this chapter is to bring these concerns into the realm of economic analysis and show that this has important implications for how agents process information and make decisions conversely the tools of economic modelling can help shed light on a number of apparently irrational behaviours documented by psychologists

the paradox of openness appropriability external search and collaboration a b s t r a c t to innovate firms often need to draw from and collaborate with a large number of actors from outside their organization at the same time firms need also to be focused on capturing the returns from their innovative ideas this gives rise to a paradox of openness the creation of innovations often requires openness but the commercialization of innovations requires protection based on econometric analysis of data from a uk innovation survey we find a concave relationship between firms breadth of external search and formal collaboration for innovation and the strength of the firms appropriability strategies we show that this concave relationship is stronger for breadth of formal collaboration than for external search there is also partial evidence suggesting that the relationship is less pronounced for both external search and formal collaboration if firms do not draw ideas from or collaborate with competitors we explore the implications of these findings for the literature on open innovation and innovation strategy 2013 the authors published by elsevier b v all rights reserved

uk industrial policy old tunes on new instruments this paper discusses the current labour government s industrial policy as most recently reflected in its document on manufacturing strategy in the context of industrial policy in the uk over the last 50 years and the form that it has taken elsewhere in europe it concludes that the thematic priorities for uk industrial policy in the 1960s international competitiveness innovation competition and skills continue to be the key themes of uk policy today the paper presents data that illustrate the gaps that exist in key indicators of performance between the uk and its main economic competitors the difference between the 1960s and the 2000s is that there are new instruments of policy two areas in particular are focused on competition policy and technology policy and an attempt is made to assess the likely effectiveness of these new instruments the paper concludes that the international evidence base for these new approaches is reasonably robust but that it is still too soon to tell if they are having the hoped for impact on the performance of the uk economy copyright 2002 oxford university press
