cost reduction competition and industry performance in many markets firms compete over time by expending resources with the purpose of reducing their costs sometimes the cost reducing investments operate directly on costs in many instances they take the form of developing new products that deliver what customers need more cheaply therefore product development can have the same ultimate effect as direct cost reduction in fact if one thinks of the product as the services it delivers to the customer in the way that lancaster pioneered then product development often is just cost reduction

cooperative and noncooperative r d in duopoly with spillovers contrary to the usual assumption made in most oligopoly models relations among firms are seldom of a wholly cooperative or noncooperative type in many situations they compete in some fields while they cooperate in others an important example is the case of cooperative research efforts bringing fierce competitors together two types of agreement are observed first r d cooperation can take place at the so called precompetitive stage companies share basic information and efforts in the r d stage but remain rivals in the market place 1 a second type of agreement involves an extended collusion between partners creating common policies at the product level the usual justifications of this extension are the difficulties of protecting intellectual property the idea is then to allow partners who have achieved inventions together to also control together the processes and products which embody the results of their collaboration in order to recuperate jointly their r d investments 2 what could be expected from these types of agreement is a reduction in r d expenditures because of less wasteful duplication and a reduction of total production because of more reprinted from the american economic review 78 5 1133 1137 1988 center for operations research econometrics 1348 louvain la neuve belgium we are grateful to jean

exports investment efficiency and economic growth in ldc an empirical investigation this study seeks to analyse the relationship between exports and growth for 19 less developed countries it utilizes multivariate causality analysis based on the error correction model to address several important hypotheses the results indicate that when exports have a causal influence in the development process that in general this is the result of their effect on both efficiency and accumulation in addition improvements in output and capital accumulation in an economy seem to have just as much of an influence on exports as exports have on output and capital accumulation finally the growth process in east asia seems to be quite different from that in southeast asia

on the organization of cooperative research and development theory and evidence abstract it has become increasingly prevalent that business firms often rival firms join forces in cooperative r and d to develop new technologies that they can use in their downstream business equity research joint ventures and non equity co development are the two major modes of organization and they differ in how ownership rights over newly developed technologies are assigned this paper addresses the question of when cooperative r and d should be carried out in a research joint venture as opposed to a co development program in a setting of contractual incompleteness the nature of the downstream business of participating firms is shown to determine the organization of cooperative r and d empirical evidence that is consistent with the theoretical analysis is also presented

learning curve spillovers and market performance this paper examines the effect of learning curve spillovers on market structure and performance we derive a simple characterization of the true marginal cost for a broad class of learning curves and use calculated examples to show that spillovers substantially undercut the barriers to entry erected by proprietary learning unlike the case of cost reducing research and development spillovers also tend to improve market performance the increased efficiency of the industrywide reduction process typically outweighs the decrease in firms incentives to reduce costs by expanding output

trade liberalization and productivity growth new evidence from the turkish rubber industry this paper empirically examines the effects of a change in foreign trade regime on productivity growth based on a generalized leontief factor demand function system total factor productivity growth tfpg rates are calculated for the turkish rubber industry during a substantial trade liberalization in the 1980s tfpg was significantly higher following trade liberalization technological change was the major contributor to this growth when a panel data estimation technique is used to explain technological change the effects of trade liberalization become clearer a one percentage point increase in the protection level led to more than a one percentage point 1 27 decline in the technological change rate

exports investments and economic development of pre accession countries of the european union an empirical investigation of bulgaria and romania this paper attempts to analyse the relationship between exports investments and economic development in two pre accession countries of the european union bulgaria and romania for investigation of this relationship a multivariate autoregressive var model is used the results of cointegration analysis showed that there is one cointegrated vector among exports investments and economic growth for the two countries granger causality tests based on error correction models ecm indicated that there is a strong granger causal relation between economic growth and exports as well as between investments and exports for the two countries in addition economic development and capital accumulation in an economy seem to have just as much of an influence on exports as exports have on capital accumulation and economic development

causal analyses between exports and economic growth in developing countries this study investigates the prima facie causal relationship between the exports and output growth in 30 developing countries over the period from 1960 to 1988 in a multivariate framework the information set considered for the output and exports models are domestic output exports labour and capital and exports domestic output exchange rate and foreign output respectively this study indentities a feedback prima facie causal relationship between exports and output growth in five countries export growth prima facie causes output growth in another six countries output growth prima facie causes export growth in a further eight countries and no causal relationship was observed between export growth and output growth in the remaining 11 countries we also found that in 15 countries the foreign exchange rate prima facie caused export growth and that in 12 countries world output caused export growth

noncooperative oligopoly and preemptive innovation without winner take all earlier models of innovation under oligopolistic rivalry are modified to include a share parameter a describing the manner in which profits are divided among rivals when one firm is successful in its search for a valuable resource stock there is a unique value of a that maximizes expected industry profits by guiding noncooperative oligopolists to choose the profit maximizing exploration rate moreover setting a at this maximizing value which always allocates some share of industry profits to the losers in the exploration race leads to an exploration rate identical to what would be chosen by a jointly managed cartel

atheoretical macroeconometrics a critique abstract the spurious nature of the restrictions used to identify many macroeconometric models has led some researchers to advocate a style of econometric inquiry that is less dependent on prior theoretical restrictions of the sort that were central to the approach of the cowles commission this development which we call atheoretical macroeconometrics is summarized and evaluated in the current paper it is contrasted with an updated version of the cowles commission approach we conclude that while some of the exercises of atheoretical macroeconometrics are valid those that have attracted the most attention and appear the most innovative exogeneity testing impulse response analysis and policy analysis using estimated vector autoregressions are based on incorrect analysis

binding constraint on economic growth under export oriented industrialization and globalization the two gap model of economic growth implies that different constraints on economic growth namely the savings and the foreign exchange availability are binding at different times this article estimates these varying binding constraints in 16 countries in east and southeast asia and latin america and explores their differences across countries regions and periods i show that the east and southeast asian countries which are recognized to be successful in export oriented industrialization are less constrained by the foreign exchange availability with reinforced export capacity than the latin american countries which had carried some inertia of import substituting industrialization policy until the 1980s in addition the economic growth turns out to be more constrained by the domestic savings in recent years which can be a reflection of capital account liberalization policies typically implemented in the late 1980s and 1990s and or a diminishing return to export led growth in either case this mi

the role of exports fdi and imports in development evidence from sub saharan african countries the disappointing economic performance of sub saharan african ssa economies in the late 1980s prompted reforms in foreign trade and foreign direct investment fdi in the early 1990s using the autoregressive distributed lag ardl approach and pedroni panel estimation procedures that allow for heterogeneity this study found that exports and fdi have a significant impact on economic growth granger type causality tests show the interrelatedness of exports fdi imports and income variables the results also provide evidence of a two stage causal chain of exports imports and income this article calls for more market oriented policy reforms in ssa countries

an analysis of cooperative research and development i analyze the effects of cooperative research whereby member firms agree to share the costs andfruits of a research project before they undertake it in this model industrywide agreements tend to have socially beneficial effects when the degree ofproduct market competition is low when there are r d spillovers in the absence of cooperation when a high degree of sharing is technologically feasible and when the agreement concerns basic research rather than development activities i show that a royalty free cross licensing agreement among any number offirms lowers the equilibrium level of innovation even though it increases the efficiency of r d through sharing

cooperative and noncooperative r d in duopoly with spillovers comment claude d aspremont and alexis jacquemin 1988 employ a simple yet elegant symmetric duopoly model of r d and spillovers to compare several equilibrium concepts these concepts include 1 the two stage noncooperative solution 2 the two stage mixed game 3 the two stage fully cooperative solution 2 and 4 the social planner s optimum 3 for each of the cases stated above they computed the equilibrium levels of output q q1 q2 and r d xl x2 x and the required second order conditions they report i for large spillovers i e b 0 5 x x x and q q q q and ii for small spillovers i e 3 x 2x x and q q q q where x denotes a firm s r d level q denotes total industry output denotes the social optimum denotes the fully cooperative model the noncooperative two stage case and the mixed game 3 is the spillover parameter here we show that comparing the pure cooperative and the pure noncooperative solutions as defined by d aspremont and jacquemin is only meaningful when the noncooperative solution is stable that is when spillovers are not too small we find that for very small spillovers in our example this occurs when 3 0 17 the d aspremont jacquemin observation holds because the noncooperative model is unstable the importance of this result rests on the fact that even though the output reaction functions cross correctly when 3 0 17 the r d reaction functions do not when 0 17 0 41 stability obtains but r d levels are higher in the noncooperative case than the fully cooperative one for large spillovers the d aspremont jacquemin result is confirmed moreover we find that the introduction of spillovers in the case of the noncooperative model tends to promote stability in the case of the cooperative model however as the level of spillovers is increased an equilibrium ceases to exist

equilibrium and optimal size of a research joint venture in an oligopoly with spillovers this paper analyzes a simple oligopoly model with information spillovers firms spend on r d to affect their costs of production the main finding is that depending on the magnitude of the spillover the market may not provide enough incentives for the optimum degree of cooperation to take place it is shown that the equilibrium size of a research joint venture is usually less than the optimum size which requires all firms to participate in the research joint venture the policy implications of this result are that there should be encouragement for firms competing in high technology industries to form industry wide cooperative agreements copyright 1995 by blackwell publishing ltd

an empirical investigation of the causal relationship between openness and economic growth in china this study investigates the causal relationship between openness and economic growth in china the integration and cointegration properties of the data are analysed and the models of granger sims geweke and hsiao are used to identify a bi directional causal relationship between gnp and exports plus imports this bi directional causation is consistent with china s development strategy of protected export promotion

the degree of spillovers and the number of rivals for maximum effective r d abstract the amount of cost reduction or effective r d that results in a symmetric sequential nash equilibrium with quadratic payoffs and differentiated goods is shown to increase with spillovers in oligopolies with a few rivals and to achieve a maximum for spillovers that are not perfect in industries with many firms similar tendencies apply for consumer surplus profits and static welfare more rivals typically lead to reduced investments output and profitability while consumer surplus and welfare increase or at least do not decrease limited entry in markets with a few rivals may enhance innovative investments profitability and consumer surplus if only product differentiation and spillovers are sufficiently high and r d costs sufficiently low too many rivals will then again lead to reductions and a decrease in static welfare

taxation and the household abstract previous analyses of demand systems and the welfare effects of taxing male and female labour supplies suppress the analysis of household resource allocation by assuming a household utility function to analyse the implications of assuming this is not the case we construct a simple but fairly general model of household resource allocation and use the properties of the equilibrium of this model to characterise the effects of tax policy on individual utilities as determined by the household resource allocation process

research joint ventures vs cross licensing agreements an agency approach abstract in this paper two broad categories of organizing a cooperative r d project are compared a research joint venture rjv and a cross licensing agreement cla in a non deterministic r d setting including asymmetric information we show that an rjv is more efficient in providing incentives it allows to capture existing synergies and facilitates the dissemination of the partners know how which is socially desirable however contrary to a cla an rjv faces the risk of opportunistic behavior by the partners regarding the provision of their know how to the venture which could lead a cla to perform more efficiently and in some cases this organization turns out to be superior

causality between export growth and industrial development empirial evidence from the nics abstract this paper investigates the causal relationship between export growth and industrial development in eight newly industrializing countries nics results of sims causality test show that for most of the nics there is a strong bidirectional causality between the growth of exports and industrial development these findings support the export led growth strategy in that expansion in exports not only promote the growth of national income but also lead to structural transformation of the developing countries

exports growth and causality in developing countries abstract previous empirical studies have interpreted results in regressions of output variables on export variables as providing support for an export promotion development strategy such an interpretation is questionable since these regressions provide no means of determining the direction of causality this paper performs causality tests between exports and growth for 37 developing countries the results cast considerable doubt on the validity of the export promotion hypothesis

exports growth and causality in ldcs abstract using akaike s optimal lag criterion in a granger causality test the causal relationship between export growth and economic growth and vice versa is re examined for 20 countries it is argued that earlier analyses which ignore optimal lags in granger or sims causality tests suffer from certain shortcomings which are overcome by the present approach the results suggest some support for the export promotion hypothesis especially in the case of well known nics and thus differ from previous applications of granger test which did not adopt an optimum lag criterion and which showed no causality from export growth to economic growth in such cases however they are inconclusive in evaluating competing hypotheses

exports export composition and growth cointegration and causality evidence for malaysia this paper comprehensively tests the export led growth elg hypothesis for malaysia for the period 1955 90 using cointegration and causality testing based on hsiao s synthesis of the granger test and akaike s minimum final prediction error criterion the results provide support for the elg hypothesis aggregate exports granger cause real gdp and non export gdp this relationship is found to be driven by manufactured exports rather than by traditional exports

r d cooperation or competition abstract the economic literature provides empirical evidence of the existence of technological cartels such as research joint ventures or deliberate sharing of technological knowledge our aim is to answer to the questions i is the creation of technological cartels beneficial from a social welfare point of view and ii do the firms have private incentives to form such cartels we depart from the approach adopted in the literature by considering a dynamic model and allowing for the possibility that the firms are asymmetric the results show the importance of the degree of existing technological spillovers and stress the differences between the symmetric and asymmetric cases

convergence to symmetry in dynamic strategic models of r d the undiscounted case abstract will r d increase or decrease the asymmetry between firms over time we examine this issue in the context of a dynamic alternate move duopoly model of non cooperative r d the asymmetry we consider is with respect to the initial stocks of technological knowledge which provides one firm a greater potential for current and future profits in the product market utilizing a value loss process constructed from the optimality equation of dynamic programming we show that for the undiscounted case the asymmetry between the firms disappears over time we obtain this convergence to symmetry result by imparting a temporal character to r d through the notion that r d investment cannot be changed instantaneously by allowing research externalities complementarity or substitutability between own and appropriated r d and either increasing decreasing or constant returns to scale in the production of technical knowledge from own and rival r d

interindustry r d spillovers rates of return and production in high tech industries this paper presents estimates of the productivity and factor bias effects of interindustry r d spillovers for five high tech industries each industry is distinguished as a separate spillover source the industries are each affected by r d spillovers and are themselves spillover sources thus a spillover network between the industries is estimated private and social rates of return to r d capital are calculated the private rates of return are generally greater than the returns to physical capital in addition the social rates of return are greater than the private rates the results show that there are significant differences between industries as to their importance as sources of r d spillovers this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item

export expansion and economic growth testing for cointegration and causality this paper develops a multivariate error correction model to test the causality between exports and growth in 15 asian countries 1967 91 the underlying series are tested as non stationary in levels but stationary in first differences the causal factors are cointegrated in five of these countries only causality test results indicate that export expansion causes growth in two third of these countries corrected for simultaneity between the causal factors a country with a large public sector higher level of economic development and which is less vulnerable to external economic shocks is more likely to reap the benefits of export promotion strategies the causal inferences are fairly stable over the sample period

cooperative and noncooperative r d in duopoly with spillovers erratum in our article published in this review volume 78 no 5 december 1988 pp 1133 37 we have shown that in the presence of sufficient spillovers of the r d benefits duopolists cooperating in r d but not in the output spend more on r d than noncooperating firms at both stages and also produce more output closest to the socially optimal level a second symmetric result is that for small spillovers duopolists cooperating neither in r d nor in output spend more on r d and produce more output than cooperative firms however this result has been obscured by an obvious inequality inversion and other typos implying a modification in the conclusions indeed in fn 13 on p 1135 one should have that x x iff

terms of trade fluctuations and economic growth in developing economies abstract the effect of terms of trade fluctuations on capital accumulation is investigated in a simple open economy stochastic growth model imported inputs make domestic capital more productive but export prices are uncertain the model s output process has a random walk component so even transient price shocks have permanent effects on output levels the size of the random walk component depends on the country s trade share the supply response of exports and other structural parameters also more variable export prices generally reduce expected domestic investment these results are consistent with the estimated variance ratios and impulse response functions for a number of ldcs

trade liberalization and environmental degradation in china being aware that trade liberalization affects the environment by scale technique and composition effects this study uses provincial data from 1993 to 2002 in china to empirically investigate how they affect the environment adopting the methodology provided by antweiler et al 2001 and slightly modifying their model this study examines whether the composition effects arising from increasing trade originate due to differences in capital labour endowment factor endowment hypothesis and or differences in environmental regulations accompanied by income growth pollution haven hypothesis in china the results indicate that the evidence of factor endowment hypothesis is found in most of the pollutants studied in this article whilst there seems no evidence of pollution haven hypothesis combining with all the estimated elasticities of scale and technique effects composition effects and trade intensity on emissions i find that increasing international trade has opposite impacts on the environment due t

money growth volatility and the macroeconomy this study analyzes the effects of variability in money growth on the macroeconomy for the period 1961 1 1984 4 within the context of a vector autoregressive model that contains variables typically included in a small macro model variance decompositions and historical decompositions are used to assess the impact of money growth variability the variance decompositions suggest substantial effects of money growth variability on the long term interest rate output and the price level historical decompositions for 1979 4 1984 4 suggest substantial effects of money growth variability on the interest rate and output but smaller effects on the price level are found copyright 1988 by ohio state university press

cost reducing and demand creating r d with spillovers this article analyzes r d policies when the returns to cost reducing and demand creating r d are imperfectly appropriable and market structure is endogenous we generalize previous characterizations of appropriability to permit the possibility that own and rival r d are imperfect substitutes we also describe how equilibrium expenditures on process and product r d as well as equilibrium market structure depend on technological opportunities and spillovers in contrast to previous work diminished appropriability does not necessarily reduce r d expenditures for example under some conditions an increase in the extent of process product spillovers will lead to an increase in product process r d we estimate several variants of the model by using manufacturing line of business data and data from a survey of r d executives
