investment and market dominance we analyze a model of oligopolistic competition with ongoing investment special cases include incremental investment patent races learning by doing and network externalities we investigate circumstances under which a firm with low costs or high quality will extend its initial lead through investments to this end we derive a new comparative statics result for general games with strategic substitutes which applies to our investment game finally we highlight plausible countervailing effects that arise when investments of leaders are less effective than those of laggards or in dynamic games when firms are sufficiently patient

profits and politics coordinating technology adoption in agriculture abstract this paper examines the political economy of government led coordination of economic activity in a simple two sector model in which individuals choice of agricultural technology affects industrialization we demonstrate the existence of multiple equilibria the economy is either characterized by the use of a traditional agricultural technology and a low level of industrialization or the use of a mechanized technology and a high level of industrialization relative to the traditional technology use of the mechanized technology increases output but leaves some population groups worse off we show that the distributional implications of choosing the mechanized technology restrict the possibility of pareto improving coordination by an elected policy maker even when we allow for income redistribution

industrial policy and firm heterogeneity our concern in this paper is with firm specific industrial policy when r d subsidies or taxes are differentiated among firms the question arises as to which firms in an industry should receive such support we analyze a situation where firms differ in their r d technologies in two distinct ways in the costs of performing r d activities and in the output obtained from such activities we find that the optimal firm specific industrial policy is affected differently by the two sources of firm heterogeneity furthermore a change in a firm s r d productivity has an ambiguous effect on the optimal policy towards the firm jel classification o31 l52 f13

evolution of population resource dynamics models abstract this paper provides a comprehensive analysis of brander and taylor s 1998 model and its descendants from the following perspectives population growth substitutability innovation capital accumulation property rights and institutional designs and modeling approach this survey aims to contribute to a better understanding of population and resource dynamics models in general and facilitate further application of the model framework to relevant circumstances although often treated as exogenous in optimal growth models making population growth an endogenous function allows us to analyze broader effects of economic activities on population the issues of substitutability innovation and capital accumulation are intertwined allowing a model to address the effect of an endogenous technological change on substitutability between natural and man made capital facilitates our analyses of sustainability issues to address internalizing inter generational externalities in resource use incorporating property right changes and institutional designs to this type of model is a useful exercise but careful attention is needed for the consistency between such an arrangement and the mathematical representation of the depicted economy finally although the common criticism regarding convenient mathematical assumptions applies to the existing bt type models the use of computer simulation can relax such assumptions to better represent the intended relationships between the relevant variables

trade policy mix ipr protection and r d subsidies this paper analyses strategic r d policy under circumstances where intellectual property rights protection resulting from firms r d investment is not perfect by examining policy choices wherein a government chooses both r d subsidies and ipr protection levels simultaneously we show that it is optimal for a government to adopt sufficiently weak ipr protection and to subsidize r d investments of domestic firms inducing r d investment of foreign rival firms will increase the profits of domestic firms ce memoire analyse une politique strategique de r d quand la protection des droits de propriete intellectuelle dpi qui decoulent d investissements en r d par les entreprises est imparfaite en examinant les choix de politiques par lesquels un gouvernement definit simultanement les niveaux de subventions pour la r d et de protection de la propriete intellectuelle on montre qu il est optimal pour un gouvernement d adopter une protection des dpi suffisamment faible et de subventionner les investissements en r d des entreprises nationales susciter un accroissement des investissements en r d des entreprises etrangeres rivales devrait augmenter les profits des entreprises nationales

green revolution land reform and household income distribution in the philippines income of agricultural households consists of returns to labor capital and land from farming supplemented mainly by labor earnings from nonfarm sources agricultural technology affects farmers income through its effect on factor demands and factor prices which in turn induce changes in the allocation of farmers own resources to different uses income from farming is also affected by village institutions such as land tenure which governs the distribution of income between landlords and tenants as well as resource allocations

r d policies trade and process innovation we set up a simple trade model with two countries hosting one firm each the firms invest in cost reducing r d and each government may grant r d subsidies to the domestic firm we show that it is optimal for a government to provide higher r d subsidies the lower the level of trade costs even if the firms are independent monopolies if firms produce imperfect substitutes policy competition may become so fierce that only one of the firms survives international policy harmonization eliminates policy competition and ensures a symmetric outcome however it is shown that harmonization is not necessarily welfare maximizing the optimal coordinated policies may imply an asymmetric outcome with r d subsidies to only one of the firms

credibility of protection and incentives to innovate in recent trade policy debates it is often argued that temporary protection stimulates innovation this paper shows that the validity of the argument depends on the perceived credibility of protection policy if it is suspected that temporary protection will be removed early should innovation occur before its terminal date the protected firm invests less in r d than it does under free trade if it is expected that protection will be extended should no innovation have occurred by its terminal date investment falls below the free trade level and eventually to zero as the terminal date is approached

an error correction model of induced innovation in uk agriculture cointegration techniques are applied to a model of induced innovation based on the two stage constant elasticity of substitution ces production function this approach results in direct tests of the inducement hypothesis which are applied to agricultural data for the united kingdom from 1953 to 2000 the time series properties of the variables are checked cointegration is established and an error correction model ecm constructed which attempts to separate factor substitution from technological change finally the ecm formulation is subjected to causality tests which show that the factor price ratio for chemicals and land is granger prior to the factor saving bias of technological change however long run relative prices are not causally prior to the machinery labour ratio this results from perturbations in the user cost of machinery caused by oil price shocks thus the induced innovation hypothesis iih may explain long run transformations like the mechanical and fertilizer revolutions that

induced innovations and farm mechanization cal change in agriculture then they come mainly from the public agent of farm technology the agricultural research system the research system should be held responsible for the social consequences of farm mechanization and it should be budgeted and directed accordingly on the other hand if mechanization and exit from farming are caused mostly by external price and wage changes the responsibility of the research system is limited principally to technology improvement in this note we discuss the newly emerging tradition of induced innovation and its relation to the alternative explanations of machine labor substitution in agriculture we first clarify the conceptual basis of the induced innovation hypothesis and the related innovation possibility function second we call into question the validity of some of the empirical applications we argue that an incomplete conceptualization of the induced innovation idea has led to invalid empirical tests and to inappropriate implications on the causes of american farm mechanization

unequal treatment of identical agents in cournot equilibrium oligopoly models where prior actions by firms affect subsequent marginal costs have been useful in illuminating policy debates in areas such as antitrust regulation environmental protection and international competition we discuss properties of such models when a cournot equilibrium occurs at the second stage aggregate production costs strictly decline with no change in gross revenue or gross consumer surplus if the prior actions strictly increase the variance of marginal costs without changing the marginal cost sum therefore unless the cost of inducing second stage asymmetry more than offsets this reduction in production costs the private and social optima are asymmetric

imports as competitive discipline the role of the productivity gap abstract this paper addresses the impact of foreign competition on the competitive advantage of domestic firms and the role of trade policy in an endogenous growth framework it shows that the impact of foreign competition on r d and productivity depends on the industry s relative position trade liberalization promotes innovation and enhances welfare in mature industries but hinders growth and leads to market exit in infant industries with a large productivity gap in the latter case temporary protection promotes the survival of the firm and increases welfare at the margin hence we integrate the old argument for the temporary protection of infant industries with the notion that foreign competition fosters innovation and productivity

antidumping protection and r d competition in recent years antidumping protection has spread throughout the world evidence shows that antidumping often targets r d intensive sectors raising a con cern that it may adversely affect worldwide investments in r d we investigate this issue in a model of reciprocal dumping extended to a two stage game in which two firms first choose r d levels and then compete in prices we find that when a single government institutes antidumping law the protected firm decreases investment in r d while the constrained firm invests more when both governments engage in antidumping actions both firms invest more in r d than under free trade jel classification f12 f13

openness and wage inequality in developing countries the latin american challenge to east asian conventional wisdom the experience of east asia in the 1960s and 1970s supports the theory that greater openness to trade tends to narrow the wage gap between skilled and unskilled workers in developing countries in latin america since the mid 1980s however increased openness has widened wage differentials this conflict of evidence is probably not the result of differences between east asia and latin america instead the conflict is probably the result of differences between the 1960s and the 1980s specifically the entry of china into the world market and perhaps the advent of new technology biased against unskilled workers

is the wto passe the wto has delivered policy outcomes that are very different from those likely to emerge out of the recent wave of preferential trade agreements ptas should economists see this as an efficient institutional hand off where the wto has carried trade liberalization as far as it can manage and is now passing the baton to ptas to finish the job this paper surveys a growing economics literature on international trade agreements and argues on this basis that the wto is not passe rather and subject to some caveats this survey of research to date suggests that the wto warrants strong support while a more cautious view of ptas seems appropriate

strategic trade and industrial policy towards dynamic oligopolies we characterise optimal trade and industrial policy in dynamic oligopolistic markets if governments can commit to future policies optimal first period intervention should diverge from the profit shifting benchmark to an extent which exactly offsets the strategic behaviour implied by fudenberg and tirole s animal spirits taxonomy of business strategies without government commitment there is an additional basis for intervention whose sign depends on the strategic substitutability between future policy and current actions we consider a variety of applications to rd spillovers consumer switching costs etc and also extensions to constrained second best policies

growth and distribution a test of the induced innovation hypothesis for the korean economy this study investigates technical change biases and their effects on distribute shars in korea we are particularly concerned with whether technical change biases have been induced by changes in relative factor prices accompanied by rapid economic growth in korea our test results show that technical change in korea has been biased in the direction in the direction for saving labour and using capital thus rendering support to the induced innovation hypothesis these findings are roughly in parallel with empirical studies on the induced innovation hypothesis for the us and japanese economies the similar pattern in technical change biases between korea and the two advanced economies is noteworthy in light of their basic differences in factor endowments another salient feature of our empirical analysis is that the price corrected labour share in korea has continually shrunk in the process of rapid economic growth which has been partly precipitated by factor price disorting policies

market based systems for reducing chemical use in agriculture in the united states this study uses a computable general equilibrium cge model of the u s economy to estimate the economic effects of agricultural fertilizer and pesticide input reductions on individual farm sectors and on the economy as a whole the costs of reducing agricultural chemicals using a market based approach and a command and control approach are compared the real cost to society of restrictng fertilizer and pesticide use by 20 percent across all uses is estimated to be 2 3 billion a market based approach that would provide incentives to reduce chemical use in the most cost efficient manner would be about 10 percent less costly

the relevance of p star analysis to uk monetary policy recent articles have attempted to restore the use of a simple measure of the money supply as an indicator of future price levels p star and to reestablish a causal link from money to prices in this paper we argue that the p star approach is flawed it is certainly more complex than traditional monetarist approaches but the fundamental questions of causality are in no way either affected or resolved we argue that the p star relationship does not have a causal link with prices but rather the causality runs from prices to money we also find that there is some causality running from money to real income so that monetary conditions do seem to have some predictive power for future levels of activity copyright 1994 by royal economic society

technology adoption and agricultural price policy market interventions such as price supports or fertilizer subsidies can lead to gains from speeding up adoption of new technologies but the policies distort resource allocation a framework is developed for optimizing policies in light of the adoption allocation trade off based on adoption coefficients and production parameters from third world agriculture levels and duration of policies are estimated sensitivity analyses are performed gains are small at best and may be zero or negative in view of farmer costs of adjustment and deadweight losses from taxes profit technology adoption if new technologies are desirable why not use price supports or input subsidies to encourage faster technology adoption while frequently raised in policy deliberations this question has received little serious analysis particularly neglected has been the conflict or trade off between a gains in output as producers switch from old to new technologies and b the losses from resource use distortions brought about by price policies when output prices are raised or prices of inputs such as fertilizer are lowered the

labor productivity measurement in japanese agriculture 1956 1990 abstract this paper investigates the factors responsible for a drastic decline in the growth rate of labor productivity of the agricultural sector for the 1956 1990 period this investigation is carried out by a newly devised procedure which decomposes the growth rate of labor productivity into 1 the total substitution effect which consists of the effects due to factor price changes and biased technological change and 2 the tfp effect composed of the effects due to scale economies and technological progress based on empirical estimation of the translog cost function it was found that the total substitution effect contributed to the growth of labor productivity much more than the tfp effect did for the period under question

changing labor market conditions and economic development in hong kong the republic of korea singapore and taiwan china in the newly industrializing economies nies of hong kong the republic of korea singapore and taiwan china the entire working population has benefited from labor market institutions the east asian nies attained and maintained generally full employment improved their job mixes raised real earnings and lowered their rates of poverty this article reaches two principal conclusions first labor market conditions continued to improve in all four economies in the 1980s at rates remarkably similar to their rates of aggregate economic growth second labor market repression was not a major factor in the growth experiences of these economies in the 1980s it thus appears that labor market repression is neither necessary nor desirable for outward oriented economic development

wage setting institutions and economic growth abstract wage setting institutions in several asian and latin american economies are compared and contrasted the asian economies have relied more on market wage determination whereas the latin american economies have encouraged institutions which push wages in key sectors up above market clearing levels market wage determination combined with exportled growth has resulted in rapidly rising real wages in the context of full employment in the asian

global population growth technology and malthusian constraints a quantitative growth theoretic perspective we structurally estimate a two sector schumpeterian growth model with endogenous population and finite land reserves to study the long run evolution of global population technological progress and the demand for food the estimated model closely replicates trajectories for world population gdp sectoral productivity growth and crop land area from 1960 to 2010 projections from 2010 onwards show a slowdown of technological progress and because it is a key determinant of fertility costs significant population growth by 2100 global population reaches 12 4 billion and agricultural production doubles but the land constraint does not bind because of capital investment and technological progress

cost manipulation games in oligopoly with costs of manipulating we analyze a class of two stage games where rival firms incur real resource costs in manipulating their marginal costs so as to influence the outcome of the game they want to play in stage two marginal costs may be manipulated by various means such as redistribution of productive assets choice of location or creation of an internal input market a general formulation of the game is provided and several applications are analyzed we show that the optimal allocation of resources within an oligopoly can be asymmetric even for ex ante symmetric firms this is an additional explanation of heterogeneity in oligopoly

geographic aggregation and induced innovation in american agriculture the induced innovation hypothesis is tested for the usa and western regions using cointegration procedures an error correction model separates short run and long run effects of relative price changes a significant difference in the elasticities of factor substitution along the isoquant and the innovation possibility curve implies induced innovation the estimated results support the hypothesis for washington the pacific northwest and the western region but not for the nation corroborative tests of weak exogeneity fail to support the hypothesis in any of the geographic units changes in output level and research investment do not significantly bias agricultural technology in the usa

social polarization industrialization and fiscal instability theory and evidence this paper is motivated by an important puzzle that arises from the contrasting macroeconomic experience across developing regions in the recent decades in sharp contrast to east asia the fiscal policies in much of latin america and sub saharan africa are characterized by large fiscal deficits and volatilities of fiscal outcomes in order to address both large deficits and volatile fiscal outcomes we develop a simple model of endogenous fiscal policy in which government spending is strategically determined by heterogeneous policymakers in a dynamic game in an economy that is highly polarized due to unequal income distribution a larger fiscal deficit results and the intertemporal fiscal policy path becomes more volatile it is because the polarization of preference leads a policymaker representing each sector to spend more for her favorite sector collectively contributing to large deficits this polarization effect implies that a shock to tax revenue is translated into a more than proportional change in spending econometric evidence provides support for these predictions countries that have suffered from the greatest fiscal instability are those with highly polarized economic societies as measured by indicators of income inequality

strategic incentives for innovations and market competition abstract we consider a principal agent model to provide a general analysis of how risk affects incentives of firms who invest in cost reducing r d and compete in the product market we specify the conditions under which higher risk reduces incentives of all firms we also examine the conditions under which an increase in risk may trigger opposite responses of rivals in the same industry some firms will strengthen while other firms will weaken the incentives provided to their agents this result holds regardless of the mode of competition in the product market cournot or bertrand as long as the rivals r d decisions are strategic substitutes it can generate new empirical implications and can provide an explanation for the lack of strong empirical support in the literature for a negative relationship between risk and incentives we also discuss policy implications regarding the effect of risk on the incentives to innovate and welfare

strategic trade policy with endogenous choice of quality and asymmetric costs abstract this paper examines strategic trade and joint welfare maximizing incentives towards investment in the quality of exports by an ldc and a developed country firms first compete in qualities and then export to an imperfectly competitive third country market under bertrand competition unilateral policy involves an investment subsidy by the low quality ldc and an investment tax by the developed country whereas jointly optimal policy calls for the reverse so as to reduce price competition by increasing product differentiation under cournot competition unilateral policy is also reversed from the bertrand outcome but jointly optimal policy involves a tax in both countries

employment income distribution and economic growth in seven small open economies resurgent interest has been manifested among development economists in trickle down i e the view that the more rapid the rate of economic growth the more rapid the improvement in employment and income distribution throughout this paper the term income distribution will refer to the location and dispersion of the pattern of incomes i e to absolute incomes and poverty and to relative income inequality empirical evidence supports trickle down in some cases but the evidence is contrary to trickle down in others the evidence from my own study of six countries experiences2 is summarised in tables i and 2

taxation and welfare in an oligopoly with strategic commitment this paper establishes comparative statics results for an oligopoly model with strategic commitment firms compete in two stages in the first stage firms decide on strategic cost reducing r d investment whereas they choose output in the second stage taking an excise tax subsidy as a shift parameter in the second stage game the short run as well as long run effects on output cost reducing r d investment and second best welfare will be examined the crucial role played by the strategic substitutability of outputs as well as cost reducing r d investments is clarified and a variant of the le chatelier samuelson principle in the authors game theoretic model is obtained copyright 1992 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

determinants of state aid to firms the case of the european automotive industry using an original database for the 1992 2008 period we investigate the determinants of state aid to the automotive industry in the european union eu we find evidence that eu policies have been effective in reducing state aid and re orienting it toward horizontal objectives however national politics still have considerable relevance during election years governments are more generous and this is particularly true in eu countries with proportional representation finally a strategic game between countries seems to take place whereby a country s decision to grant aid seems to be responsive to aid previously granted by other member states

a reversal of fortune for korean women explaining the 1983 upward turn in relative earnings between 1971 and 1983 korea s mean gender earnings ration remained virtually stagnant at 47 percent but after 1983 the earnings ration took a distinct turn upward in other words not until after 1983 did korean women make any progress in closing the gender earnings gap when controlling for education the analysis reveals a surprising drop in relative earning across education groups in the 1970s and early 1980s and a recover thereafter the author uses an extremely rich set of microdata suitable for decomposition to explain the trends in korea s earnings differential results indicate that most of the 1983 reversal is attributable to a strong compression in market returns to skills and to narrowing gender differences in education and experience the widening gender earnings differential across education groups before 1983 resulted primarily from a growing gender gap in unobserved characteristics growing gender differences in unmeasured ability or increased wage discrimination could explain this trend after 1983 women with high school education or less benefit primarily from a dramatic narrowing in the economy s distribution of market payoffs to skills enough for women to begin to catch up to men relative earnings a compression in the return to skills helped only some groups women with college educations did not experience increased benefits from changes in the market payoff to skills stricter enforcement of korea s equal pay for equal work provision could help reduce the outright discrimination against women workers that might be the underlying problem by boosting the potential of korea s female labor force stronger enforcement of korea s equal opportunity provisions would improve the country s economic productivity

intimidating competitors endogenous vertical integration and downstream investment in successive oligopoly this paper examines the interplay of endogenous vertical integration and cost reducing downstream investment in successive oligopoly analyzing a linear cournot model we establish the following key results i vertical integration increases own investment and decreases competitor investment intimidation effect ii asymmetric integration is a non degenerate equilibrium outcome iii compared to a benchmark model without investment complete vertical separation is a less likely outcome we argue that these findings generalize beyond the linear cournot model under reasonable assumptions

welfare impacts of alternative public policies for agricultural pollution control in an open economy a general equilibrium framework a general equilibrium approach is used to evaluate the welfare impacts of alternative policies for reducing agricultural pollution in an open economy with preexisting distortions caused by income taxes and agricultural subsidies the policies examined here include the removal of distortionary agricultural subsidies we find that even though these distortions are small compared to others in the economy removing them and imposing nitrogen reduction subsidies and or output taxes can enhance welfare and reduce nitrogen pollution thereby leading to a substantial double dividend the relative efficiency of the alternative policies examined here depends on the level of the nitrogen reduction target copyright 2008 oxford university press

specification of production functions for analyzing technical change and factor inputs in agricultural development abstract this paper focuses on some vital issues involed in specifying the number of variables to be included in agriculture s production function and on the functional form that the agricultural production function should assume in the context of a computable general equilibrium model when land and intermediate inputs seeds and fertilizers as well as capital and labor are included modeling the agricultural sector can best be done in a more disaggregated format than simple cobb douglas or ces specifications after examining the transcendental logarithmic production function the paper proposes to adopt nested ces specifications on the basis of empirically observed elasticities of substitution

the sensitivity of strategic and corrective r d policy in oligopolistic industries abstract we evaluate the case for r d subsidies in export sectors when the outcome of r d is uncertain and the product market is oligopolistic when r d reduces expected costs in the particular sense of first order stochastic dominance a national strategic basis for r d subsidies exists whether firms choose prices or quantities this must be balanced against a corrective incentive to tax r d whenever the number of domestic firms exceeds one however when r d increases the riskiness of the cost distribution as well the results may switch there emerges a strategic incentive to tax and a corrective incentive to subsidize r d

endogenous protection foreign direct investment and protection building trade abstract we introduce the possibility of foreign direct investment fdi in a strategic oligopolistic setting with endogenous protection and find that a number of unique subgame perfect equilibria may arise including a new result we call protection building trade this phenomenon occurs in our model when foreign firms locating production in the home country try to increase protectionist pressures in the home country through increased exports to provide larger barriers against other foreign competitors in future periods we discuss how the foreign firm behavior surrounding significant u s protectionist actions including the vers on japanese automobiles may be consistent with protection building trade behavior

vertical coordination antitrust law and international trade this paper demonstrates that vertically aligned private or public organizations are capable of generating strategic trade advantage similar to that acquired through direct government export subsidization the model considers two forms of vertical coordination that lead to advantageous trade positions in international markets upstream vertical restraint and downstream equity sharing such practices are commonly employed both by state trading agencies and by private firms in nations with lenient antitrust laws the finding has important implications under new world trade organization wto rules intended to reduce government intervention in international transactions recent reforms in the wto favor nations that sanction highly refined vertical linkages between firms while nations with stringent antitrust legislation have an incentive to negotiate for greater harmonization of international laws

beneath the miracle labor subordination in the new asian industrialism this important study examines the dynamics of the remarkable economic transformation of south korea singapore taiwan and hong kong which has been based in large measure on the production of manufactured goods for export the competitive edge of these countries has in turn been rooted in the mobilization of a low cost disciplined and productive workforce this study seeks therefore to explain how east asian governments and employers have attempted to manage this workforce it also explores the extent to which workers are able to challenge management decisions and insert working class agendas into public policy beneath the miracle moves beyond current explanations for the weakness of east asian labor movements which emphasize confucianist culture material welfare gains and political repression it shows that the organizational capacity of workers has been more fundamentally undercut first by the nature of emergent east asian employment systems and second by the sequencing of developmental change with political controls preceding rapid industrialization and preempting political and union organization of the growing industrial workforce deyo undertakes an incisive cross national comparison of employment systems and explores anomalous situations such as that in hong kong where labor is politically weak even under minimal state controls and that in south korea where labor is in a stronger position despite far stricter regulation beneath the miracle offers a fresh and compelling comparative analysis of asian labor movements which could lead to a reassessment of many other developmental issues in east asia in his probing examination deyo provides an important and exciting contribution to the literature in this field

testing the induced innovation hypothesis an error correction model of south african agriculture abstract this paper applies cointegration techniques to a model of induced innovation based on the two stage constant elasticity of substitution ces production function this approach results in direct tests of the inducement hypothesis which are applied to data for south african commercial agriculture for the period 1947 1991 south african data is used because the policy changes have been substantial enough that the factor and price ratios have turning points rather than being monotonic the time series properties of the variables are checked cointegration is established and an error correction model ecm constructed allowing factor substitution to be separated from technological change finally the ecm formulation is subjected to causality tests which show that both the factor price ratios and r d and extension expenditures are granger prior to the factor saving biases of technological change thus each stage of the analysis corroborates the inducement hypothesis however straightforward price inducement is only part of the explanation of changes in factor ratios policy induced innovation in response to tax concessions and subsidised credit is also present

an east asian model of economic development japan taiwan and south korea the east asian model of economic development focuses on 5 shared characteristics that seem significant in the contemporary economic development of japan taiwan and korea they are economic characteristics and include 1 high investment ratios 2 small public sectors 3 competitive labor markets 4 export expansion and 5 government intervention in the economy large and efficient investments in human capital and well developed capacities to absorb new technology are 2 other economic features shared by the three one could add overcrowding high man land ratios and scarcity of natural resources though these are handicaps rather than sources of economic strength it is possible however that virtue springs from necessity and that ample arable land or abundant natural resources mainly permit governments to postpone the difficult decisions needed to promote development rather than provide the wherewithal needed to finance development other noneconomic characteristics of the three such as ethnic and linguistic homogeneity relatively compact geography manageable population size and the confucian tradition have not been considered in the model even though they have undoubtedly influenced labor productivity savings behavior and other aspects of economic performance whether the east asian model ought to be followed depends on whether current and foreseeable circumstances are sufficiently like those faced by the three to justify using the same policies that they used applicability of the east asian model should also depend on whether the strategy employed by the three has been responsible for their economic success 2 aspects of the east asian models policy features are noteworthy 1 the policies typically work by influencing rather than replacing private market decisions and 2 the public expects government to intervene to influence economic growth

technology policy and the organization of r d abstract in this study we examine how technology policy in the form of r d subsidies and encouragement of research joint ventures rjvs affects the investment incentives of firms in various types of imperfectly competitive markets we find that joint ventures yield lower research intensities in the absence of subsidies in the presence of optimal subsidy policy higher expected welfare is obtained with rjvs but the optimal policy may also involve a more costly subsidy program the analysis also identifies possible difficulties in implementing socially optimal policies arising from private incentives conflicting with the public interest

induced bias of technical change in agriculture the united states and japan 1880 1980 because of extreme differences in factor endowments and price ratios among factors between the united states and japan both countries have experienced sharply different patterns of factor use and productivity growth in agriculture for the past 100 years of modern economic growth in this study the method of testing the hicksian hypothesis of induced innovation was developed using the two level ces production function the model was applied to the historical data of u s and japanese agricultural development for 1880 1980 the results were consistent with the hypothesis that different patterns of technical change in the two countries were induced by differences in the levels and the movements in relative factor prices

the sensitivity of strategic and corrective r d policy in battles for monopoly the authors characterize the role for r d subsidies in export markets where r d is an uncertain process and the winner of the r d competition monopolizes the market investments are assumed to induce either first order or mean preserving second order shifts in the distribution of a firm s costs or reinterpreting the model as a patent race a firm s discovery dates the authors show that regardless of which form the uncertainty takes a national strategic incentive to subsidize r d exists but must be balanced against a national corrective incentive to tax r d whenever a country has multiple firms involved in the r d competition copyright 1992 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

globalization and the decline of the welfare state in less developed countries why have trends in government welfare spending in developing countries diverged from those in developed countries i address this question by investigating the effects of capital and trade flows on government welfare spending in fifty three developing countries using an original measure of labor power in developing countries i test the links between international markets labor s political strength and the welfare state i argue that labor s collective action problems caused by large populations of low skilled and surplus workers offset labor s potential political gains from globalization i show that when the proportion of low skilled workers in a nation is high globalization will lead to a decline in welfare spending most significantly the results suggest that in nations where labor market institutions are not yet well developed government social welfare spending is constrained by international market forces

induced innovation in u s agriculture time series direct econometric and nonparametric tests the hypothesis of induced innovation is tested for u s agriculture using a high quality state level panel data set and three disparate testing techniques time series direct econometric and nonparametric we find little support for the hypothesis that conclusion is robust across testing techniques however as with all empirical tests of this hypothesis conducted to date ours focus only on the demand side of the hypothesis the hypothesis could have been rejected simply because the marginal cost of developing and implementing input saving technologies for the relatively expensive inputs is greater than for the relatively cheap inputs copyright 2009 oxford university press

international r d rivalry and industrial strategy this paper presents a theory of government intervention which provides an explanation for industrial strategy policies such as r d or export subsidies in imperfectly competitive international markets domestic net welfare is improved by the capture of a greater share of the output of rent earning industries although the subsidy ridden noncooperative international equilibrium is jointly suboptimal behaviour of governments and firms is modelled as a three stage subgame perfect nash equilibrium the assumption that the government is the first player in this game allows it to influence equilibrium outcomes by altering the set of credible actions open to firms

competition and investment a unified approach using a simple but general two stage framework this paper identifies the circumstances under which increasing competition leads to more cost reducing investments the framework can for instance capture increasing substitutability for different types of oligopoly models or changes from cournot to bertrand competition the paper identifies four transmission mechanisms by which competition affects investment for a firm with lower initial marginal costs higher efficiency a positive effect of competition on investment is more likely positive spillovers support a negative effect of competition on investment the relation between competition and investment is not affected in an unambiguous way by the level of pre existing competition
