national technology gaps and trade an empirical study of the influence of globalisation abstract this paper examines the hypothesis that economic internationalisation is acting to reduce the importance of national technology gaps as determinants of trade patterns and performance the cross country analysis uses two approaches to assess the dynamic nature of the relationship between national investment in technological capability proxied by both r d activity and human capital and technology intensive ti trade performance natural resource endowment and the changing impact of physical capital formation are also investigated the study includes approximately 48 nations and is based on data from the mid 1970s to 1990 the empirical evidence from one approach undertaken does not support the globalisation hypothesis as national investment in technology and human capital is shown to have maintained its link to international trade success in ti manufactures over the study period however the findings of the alternative approach are ambiguous a positive association between technology investment catch up and ongoing ti manufacturing trade performance is evident for the newly industrialised economies nics but the results suggest that an inverse relationship may apply for many of the mature western economies

patent validation at the country level the role of fees and translation costs one feature of the european patent system that is heavily criticized nowadays is related to its complex fragmentation and the induced cost burden for applicants once a patent is granted by the epo the assignee must validate and often translate it and pay the renewal fees to keep it in force in each country in which the applicant seeks protection the objective of this paper is to assess to what extent validation and renewal fees as well as translation costs affect the validation behavior of applicants we rely on a gravity model that aims at explaining patent flows between inventor and target countries within the european patent system the results show that the size of countries their wealth and the distance between their capital cities are significant determinants of patent flows validation fees and renewal fees further affect the validation behavior of applicants translation costs seem to have an impact as well the important role played by fees suggests that the implementation of cost reducing policy interventions like the london protocol would induce a significant increase in the number of patents validated in each european country

is there an inflation productivity trade off some evidence from the manufacturing sector in greece this paper examines the effect of inflation on total factor productivity growth tfp using time series data for every two digit greek manufacturing industries in order to do the above a translog flexible cost function is estimated and used to decompose tfp growth into scale economies inflation and technical change the advantage of estimating a very general and flexible cost function is that it allows us for the first time to examine empirically a large number of significant relationships between tfp growth and economies of scale inflation and technical change the main conclusion drawn from this analysis is that inflation reduces tfp growth in a way which is sizeable furthermore using standard causality test the direction of causality between inflation and tfp growth was tested at the manufacturing level

what makes basic research economically useful abstract economic analysis has helped us understand the strong economic dimension in the explosive growth of science and more recently the reasons for continuing public subsidies however the growing domination of the market failure approach has led to the analytical neglect of two major questions for policy makers how does science contribute to technology are the technological benefits from science increasingly becoming international on the former too much attention has been devoted to the relatively narrow range of scientific fields producing knowledge with direct technological applications and too little to the much broader range of fields the skills of which contribute to most technologies on the latter national systems of science and of technology remain closely coupled in most major countries in spite of the technological activities of large multinational firms empirical research is needed on concentration scale and efficiency in the performance of basic research where techniques and insights from the applied economics of industrial r d are of considerable relevance there is no convincing evidence so far of unexploited economies of scale in basic research this evidence shows that many policies for greater selectivity and concentration in basic research have been misconceived economists and other social scientists could help by formulating more persuasive justifications for public subsidy for basic research and by making more realistic assumptions about the nature of science and technology

inflation and social consensus in the seventies it is widely believed that the two oil price shocks of the i 970s played a major role in the increase in inflation in industrial countries while this hypothesis is consistent with the timing of changes in inflation at the global level it seems to break down when applied to individual countries cross sectionally for example over the period i973 9 switzerland had an average inflation rate of 4 7 while in neighbouring italy inflation averaged i5 6 over the same period furthermore inflation in the pre opec period i97i 2 was actually higher in switzerland than in italy it seems that a supply shock explanation of inflation in the seventies also requires an explanation of why different countries responded so differently to a similar set of shocks at the world level the purpose of this paper is to offer such an explanation and to test the hypothesis with a cross sectional equation accounting for differences in average inflation rates over the period i973 9 in eighteen oecd countries this time period includes the year of the first opec shock i 973 and the following six years up to the time of the second opec shock the hypothesis to be tested is set in the framework of a model similar to that of brunner et al i 980 the key features of the brunner model are that the adjustment of real wage expectations is subject to lags and that labour supply is positively related to the difference between the perceived real wage and the expected or target real wage given these two assumptions a negative supply shock gives rise to a period of stagflation whose intensity will be greater the slower is the speed of adjustment of real wage expectations the model of this paper extends the brunner model in three ways first across countries the speed of adjustment of real wage expectations or targets is assumed to depend positively on the degree of social consensus as proxied negatively by an indicator of average long run strike activity second the model allows for the possibility of inflation inertia or systematically incorrect inflation expectations as well as a sluggish adjustment of real wage expectations third the model incorporates the hypothesis that money supply growth will vary across countries according to variations in inflationary pressures as perceived by governments the first section of the paper provides a discussion of the rationale for the key proposition regarding strikes and social consensus as well as a brief discussion of the role of wage bargaining institutions section ii develops a theoretical model which yields a reduced form cross sectional equation relating the average i 973 9

technological capabilities and industrialization abstract this paper reviews the implications for industrial strategy of recent research on technological capabilities at the firm and national levels after exploring the nature and determinants of microlevel technological development a simple framework for explaining the growth of national capabilities is set out based on the interplay of incentives capabilities and institutions each may suffer market failure and so require corrective intervention the experience of some industrializing countries is described to assess the validity of this framework it is concluded that interventions carefully and selectively applied are necessary for industrial success

endogenous implementation of technology gap in energy optimization models a systematic analysis within times g5 model evaluation of global diffusion potential of learning technologies and their timely specific cost development across regions is always a challenging issue for the future technology policy preparation further the process of evaluation gains interest especially by endogenous treatment of energy technologies under uncertainty in learning rates with technology gap across the regions in global regional cluster learning approach this work devised implemented and examined new methodologies on technology gaps a practical problem using two broad concepts of knowledge deficit and time lag approaches in global learning applying the floor cost approach methodology the study was executed in a multi regional technology rich and long horizon bottom up linear energy system model on the integrated markal efom system times framework global learning selects highest learning technologies in maximum uncertainty of learning rate scenario whereas any form of technology gap retards the global learning process and discourages the technologies deployment time lag notions of technology gaps prefer heavy utilization of learning technologies in developed economies for early reduction of specific cost technology gaps of any kind should be reduced among economies through the promotion and enactment of various policies by governments in order to utilize the technological resources by mass deployment to combat ongoing climate change

ex post redistribution in a federation implications for corrective policy abstract this paper analyzes whether changes in the timing of equalizing transfers to state governments necessitate an adjustment in federal corrective policy according to the existing literature assuming an ex ante choice of transfers the corrective grant is equal to the marginal damage benefit inflicted by externality generation when the federal government accommodates state finances ex post the grant differs in formula from existing prescription allocative federal policy corrects state policy incentives twofold it entails a correction for the distortion in the marginal benefit of state spending as in earlier literature and for the distortion in the marginal cost of public funds induced by the ex post provision of transfers the required grant rule is generically disproportionate to the equilibrium externality even with lump sum taxation furthermore the ex post provision of transfers is critical for the nature of the equilibrium inefficiency equalizing transfers at least partly internalize consumption spill overs but simultaneously establishes a new source of inefficiency as a final result the existing prescription for allocative federal policy continues to apply if the public good is pure

the growth and convergence of manufacturing productivity in industrial and newly industrialising countries abstract this paper focuses on the manufacturing sector of specific economies to examine why their growth rates differ the technology gap approach is adopted to show the relevant role of technological change on national manufacturing productivity growth the productivity convergence hypothesis was partially supported by the results the results also produce empirical evidence of the importance of the inputs of the technological gap model to countries at different levels of manufacturing development the estimated models suggest that the input coefficients might be related to the gap of a country to the leader

panacea pandora s box or placebo feedback in bank mortgage backed security holdings and fair value accounting we examine the relation between bank holdings of mortgage backed securities mbs and mbs prices theory suggests feedback between mbs holdings and underlying asset markets can be aggravated by mark to market accounting we measure feedback by the relation between asset returns and the changes in bank mbs holdings consistent with the existence of feedback effects related to mark to market we find that for banks with high mbs more nonperforming loans and lower total capital ratio changes in bank mbs positions are positively associated with changes in mbs prices and that this relation is reduced after the april 2009 mark to market rule clarification to assess the effect of feedback on shareholder value we test whether the stock price response of banks to the announcement of the mark to market accounting rule clarification is associated with the intensity of feedback behavior we find that the stock market reaction to the rule change is more positive for banks with more mbs higher nonperforming loans and higher pre rule change feedback we also find positive bond price reactions to the rule change overall our results suggest feedback related to mark to market accounting had a measurable effect on shareholder value 2011 published by elsevier b v

hedging speculation and shareholder value abstract we document that gold mining firms have consistently realized economically significant cash flow gains from their derivatives transactions we conclude that these cash flows have increased shareholder value since there is no evidence of an offsetting adjustment in firms systematic risk this finding contradicts a central assumption in the risk management literature that derivatives transactions have zero net present value and highlights an important motive for firms to use derivatives that the literature has hitherto ignored although we find considerable evidence of selective hedging in our sample the cash flow gains from selective hedging appear to be small at best

public goods self selection and optimal income taxation using the self selection approach to tax analysis this paper derives a modified samuelson rule for the provision of public goods when the government deploys an optimal nonlinear income tax this approach gives a straightforward interpretation of the central result in this area generalises it and provides a simple characterisation of optimal policy in a wide range of circumstances the analysis also emphasises and clarifies the significance of the choice of numeraire for the optimality of decentralising public spending decisions it is well known that the famous samuelson rule for the provision of public goods may not be applicable when the tax revenues used to finance the public goods come from distorting taxes the principle was recognized as long ago as pigou 1947 long before the samuelson rule was devised pigou saw that in addition to the resource cost involved in transferring funds from the private to the public sector there was a deadweight loss involved from this insight he suggested that the criterion for providing public goods should be more stringent than the samuelson rule would later suggest in particular one might expect that the inclusion of the deadweight loss of taxes as part of the cost of providing a public good would lead to a reduction in its optimal provision relative to a situation in which lump sum taxes were available the problem was investigated more systematically by atkinson and stern 1974 who considered the case in which a public good is financed by a set of optimal commodity taxes all individuals were assumed to be identical so efficiency alone dictated the objective they found that no prima facie case could be made for the pigou position that the use of distortionary taxes called for a reduction in the supply of the public good their analysis clearly showed that there were two influences at work when the financing of a public good was by distorting taxes on the one hand

measuring innovative performance is there an advantage in using multiple indicators abstract the innovative performance of companies has been studied quite extensively and for a long period of time however the results of many studies have not yet led to a generally accepted indicator of innovative performance or a common set of indicators so far the variety in terms of constructs measurements samples industries and countries has been substantial this paper studies the innovative performance of a large international sample of nearly 1200 companies in four high tech industries using a variety of indicators these indicators range from r d inputs patent counts and patent citations to new product announcements the study establishes that a composite construct based on these four indicators clearly catches a latent variable innovative performance however our findings also suggest that the statistical overlap between these indicators is that strong that future research might also consider using any of these indicators to measure the innovative performance of companies in high tech industries

a multilevel analysis of innovation in developing countries innovation is a multilevel phenomenon not only characteristics of firms but also environment within which firms operate matter although this has been for long recognized in the literature a quantitative test that explicitly concerns the hypothesis that framework conditions affect innovativeness of firms remains lacking using a large sample of firms from many developing countries we estimate a multilevel model of innovation that integrates explanatory factors at different levels of the analysis apart from various firm s characteristics national economic technological and institutional conditions directly predict the likelihood of firms to innovate

the recent slowdown of productivity growth the slowdown of productivity growth in the developed countries during the seventies will in this paper be viewed as a combined effect of three closely interacting forces i a long term deterioration in the efficiency and flexibility of some basic mechanisms of the economic and political systems of these countries ii the fading away of a number of uniquely favourable circumstances for productivity growth during the fifties and sixties and iii the exposure of these economies to unusually severe macroeconomic disturbances in the seventies careful inspection of time series with attempted modifications for cyclical factors suggests that there was hardly any general slowdown of productivity growth among developed countries before approximately i972 4 1 as we know the situation is radically different since then labour productivity growth per year for the entire national economy gdp per man hour seems to have fallen between the periods i960 73 and i973 9 by about i 2 percentage points in the united states 45 by about 24 percentage points in western europe2 45 and by about 5 9 percentage points in japan 6o table i see also fig i the slowdown was of about the same size in the business and manufacturing sectors see table i to calculate the extent of the slowdown of total factor productivity growth is of course a much more hazardous matter to which i will return later if just the various system changes and the fading away of the uniquely favourable factors had been the dominating forces behind the productivity growth slowdown we would expect the slowdown to have been gradual rather than abrupt as it turned out to be this abruptness as well as its timing makes the dramatic macroeconomic disturbances around i972 4 a prime suspect when looking for the villain behind the productivity growth slowdown indeed it is a basic hypothesis of the paper that these macroeconomic disturbances were not only by themselves strongly unfavourable for productivity growth but that they also revealed and accentuated the gradual deterioration of the

classical unemployment accommodation policies and the adjustment of real wages a model of wage formation and stabilization policy in economies with strong trade unions is developed the analysis provides a theoretical underpinning for the assertion that accommodation policies may cause wage inflation and ultimately reduce employment various methods of accomplishing a real wage adjustment are discussed i a policy of complete nonaccommodation 2 continued accommodation policies but with lower employment targets 3 social contracts and 4 tax based incomes policies tip

an empirical analysis of patents flows and r d flows around the world in this article we empirically investigate the effect of research and development r d flows on patent flows around the world we do this using an unbalanced panel consisting primarily of organization for economic co operation and development oecd countries that have both patent and r d expenditure information broken down by domestic and foreign sources our analysis shows that even among a fairly homogeneous group of countries the sources of patents and r d differ substantially using a dynamic panel framework we find that domestic r d per capita increases domestic patents per capita only for the european patent convention epc countries that already have a decentralized approach to innovation foreign r d per capita increases foreign patents per capita in all countries even though foreign r d constitutes a very small fraction of total r d we find that some of these differences can be attributed to the locations of the patent applications including those to the european patent office epo unit

energy price shocks and productivity growth in us and uk manufacturing because sustained changes in the trend of productivity growth are so very important for people s long run economic welfare the dramatic productivity growth slowdown of the 1970 s and early 1980 s has been the focus of much analysis and discussion for some observers it was much more than coincidence that the oil price shocks of 1973 74 accompanied the sharp slowdowns in traditionally measured productivity growth not only in the united states and the united kingdom but throughout the industrialised world however establishing quantifying and explaining sig nificant linkages between energy price shocks and productivity growth has proved to be most difficult traditional and time honoured relationships involving productivity growth have all seemed incapable of explaining this slowdown for example edward denison author of several widely cited productivity studies has concluded that energy had essentially no role in explaining the productivity growth slowdown and that moreover what happened is to be blunt a mystery 1979 p 4

the assessment productivity and competitiveness in british manufacturing this issue of the oxford review examines productivity and competitiveness in british manufac turing the simplest and most widely used measure of productivity is output per head from this definition sprout at once the horns of a dilemma for an economy facing unemployment on the present scale for a given rate of expansion of output the higher the rate of productivity growth the greater the decline in employment or at least the smaller its growth on the other hand in an economy open to international competition a high rate of productivity growth relative to that of other countries is the long term key to achieving the favourable international competitive po sition necessary to sustain growth and a low level of unemployment

foreign patenting in the u s as a technology indicator the case of norway abstract foreign patenting in the u s has been considered to be a useful technology indicator in comparisons between countries in order to shed light on this topic this paper will try to explain foreign patenting in the u s by way of data for one country norway a crucial question is what role is played by exports in explaining the foreign patent activity is the u s patenting just an indicator of the export performance or is it the other way around that technology measured by foreign patent activity is an important trade explanatory variable the first part of this paper deals with the relationship between norwegian u s patenting and export to the u s by way of time series analysis on data from 1883 to 1980 then some more detailed analysis are done on industry level data from 1920 and from 1960 1980 an hypothesis is further tested for the possible relationship between foreign u s patenting and the international business cycles finally a detailed but tentative analysis is done on firm level data for the years 1969 1980 the results lend partial support to the assumption that foreign u s patent activity reflects innovative activity in the country where the patents originated a major advantage in using foreign patenting in the u s as a technology indicator is that this type of data in general seems to be of a higher quality than domestic patent data

industrial governance structures innovation strategies and the case of japan sectoral or cross national comparative analysis in comparative research on industrial policy strategies attention has shifted from national level variables to sectoral variables in both the description and the explanation of policy the sectoral literature however lacks analytic focus and has provided little systematic insight into the causes of cross sectoral variance in governance structures and policy strategies based on recent contributions to the economics and sociology of formal organizations this article attempts to sharpen the concept of industrial sector and to provide a rationale for why sectoral structures and strategies vary next it develops a synthetic explanatory framework that combines sectoral analysis and national domestic structuralism in order to account for industrial innovation strategies in advanced capitalist countries in the final section the fruitfulness of this approach is illustrated by developing a new account of japan s success and failure in industrial innovation an account that overcomes the contradictions among the main alternatives offered in the past the key objective of the article however is to develop a new set of theoretical hypotheses for cross national research not a rigorous empirical test of its main propositions

industrial research as a source of important patents abstract it has been recently observed that in the light of concepts like lean management shortening of development times business reengineering or shareholder value companies have substantially cut down their expenditures for research since research is by definition primarily aimed at the broadening of technological knowledge rather than the development of products or processes which find immediate commercial applications the benefits of research are not apparent and hence the allocation of funds to research appears to be unjustified based on data from 25 european and japanese electronics companies we examined the relationship between corporate spending on research and patenting output since patent applications only measure the overall level of r d activity they were differentiated according to their quality in order to assess the technological and commercial impact of r d activities it is found that those companies which spend a high share of their r d expenditures on research hold patents of relatively higher quality furthermore differences between european and japanese companies with respect to research spending and patent positions are identified the results lead to the conclusion that research obviously serves as a base for those inventions which are of higher technological and commercial importance thus the investment in research appears to be of great value for the competitiveness and should therefore not be neglected

the reliability of investment property fair value estimates abstract we investigate the reliability of mandatory annual fair value estimates for uk investment property we find that appraisal estimates understate actual selling prices and are considerably less biased and more accurate measures of selling price than respective historical costs investigations of managerial discretion over fair value reporting reveal that managers select among permissible accounting methods to report higher earnings time asset sales to smooth reported earnings changes smooth reported net asset changes and boost fair values prior to raising new debt finally we find that the reliability of appraisal estimates increases when monitored by external appraisers and big 6 auditors

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

fair value accounting and managers hedging decisions real effect of fair value accounting we conduct two experiments with experienced accountants to investigate how fair value accounting affects managers real economic decisions in experiment 1 we find that participants are more likely to make suboptimal decisions e g forgo economically sound hedging opportunities when both the economic and fair value accounting impact information is presented than when only the economic impact information is presented or when both the economic and historical cost accounting impact information is presented this adverse effect of fair value accounting is more likely when the price volatility of the hedged asset is higher which is a situation where paradoxically hedging is more beneficial we find that the effect is mediated by participants relative considerations of economic factors versus accounting factors e g earnings volatility experiment 2 shows that enhancing salience of economic information or separately presenting net income not from fair value remeasurements reduces the adverse effect of fair value accounting our findings are informative to standard setters in their debate on the efficacy of fair value accounting

capabilities economic development sustainability the capability concept is commonly used in analyses of firms however as this paper shows it may also be used at the level of nations factor analysis is used on a broad set of relevant indicators to derive composite measures of national technological and social capabilities the data covers 114 countries worldwide on different levels of development for the period 1995 2013 the paper then analyzes the relationships between these capability measures and economic development defined in various ways and controlling for other relevant factors the results suggest that improving national technological and social capability is a must for achieving sustainable economic development and improving living conditions

foreign patent flows to and from the united kingdom abstract a substantial part of the stock of technological knowhow in any given country is determined by foreign companies flows of technology are reflected in part by the international pattern of patenting behaviour this paper examines both the patent applications in the uk by foreign countries and uk patent applications abroad it concludes that each country is exposed to a subset of world wide technology determined by the profitability of transfer of new knowhow profitability is affected by the size of potential supply of new inventions in donor countries by the attractiveness of markets for knowhow in recipient countries and by the costs of transfer

the rewards to meeting or beating earnings expectations abstract this paper finds that firms that meet or beat current analysts earnings expectations mbe enjoy a higher return over the quarter than firms with similar quarterly earnings forecast errors that fail to meet these expectations further such a premium to mbe although somewhat smaller exists in the cases where mbe is likely to have been achieved through earnings or expectations management the findings also indicate that the premium to mbe is a leading indicator of future performance this premium and its predictive ability are only marginally affected by whether the mbe is genuine or the result of earnings or expectations management

pure public goods and income redistribution in a federation with decentralized leadership and imperfect labor mobility abstract we examine the non cooperative provision of a pure public good by regional governments in a federation similar to the european union where regional governments are stackelberg leaders and the central government is a stackelberg follower a federation with decentralized leadership the center makes interregional income transfers after it observes the contributions to the pure public good imperfectly mobile workers react to regional and central governments policies by establishing residence in their most preferred region despite the degree of labor mobility we show that the pure public good and interregional transfers are generally allocated efficiently in a federation with decentralized leadership

taking a view corporate speculation governance and compensation using responses to a well known confidential survey we study corporations use of derivatives to take a view on interest rate and currency movements characteristics of speculators suggest that perceived information and cost advantages lead them to take positions actively that is they do not speculate to increase risk by betting the ranch speculating firms encourage managers to speculate through incentive aligning compensation arrangements and bonding contracts and they use derivatives specific internal controls to manage potential abuse finally we examine whether investors reading public corporate disclosures are able to identify firms that indicate speculating in the confidential survey they are not derivative instruments can be used to hedge market risk exposures or to spec ulate on movements in the value of the underlying asset to hedge generally implies that the derivative position is taken with the intention of reducing risk to speculate generally implies that the derivative position is undertaken with the primary intention of making a profit or increasing risk speculation has a pejorative connotation in the financial press yet it is not clear that this repu tation is deserved in this paper we explore whether speculation is an activity that is optimal ex ante but for which we should expect to observe some large negative outcomes ex post or whether it is an activity that will decrease ex pected shareholder value to the benefit of agents of the firm that is whether it is evidence of an agency problem and governance failure the extant theoretical and empirical literature presents an abundance of ev idence about why firms should and do use derivatives to hedge 1 we know

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

a critical realist interpretation of evolutionary growth theorising the article discusses a critical realist interpretation of evolutionary growth theorising by focusing on some of its basic characteristics the evolutionary ontology is complex differentiated structured systemic open ever changing and radically uncertain its methodology tends to be increasingly based on appreciative theorising retroductive explanations and interdisciplinary analysis after discussing these features the article suggests that critical realism may indeed constitute an important philosophical and methodological foundation for the future development of evolutionary theories of economic growth

the effect of innovation activities on innovation outputs in the brazilian industry market orientation vs technology acquisition strategies abstract this research investigates innovation in brazil one of the largest emerging economies in latin america more specifically we aim to understand how innovation activities conducted in brazilian industrial sectors innovation input are related to and affect innovation results innovation output the paper presents a quantitative analysis of a comprehensive nation wide government sponsored innovation survey pintec covering more than 30 000 companies and 34 industrial sectors data from pintec reports were analyzed by means of pca and 2sls regression our results show that brazilian industry tends to adopt two main opposite innovation strategies market orientation or technology acquisition the market orientation strategy prioritizes internal and external rd these activities showed a positive effect on innovation output on the other hand a technology acquisition strategy based on industrial machinery and equipment acquisition showed a negative effect on innovation output moreover our results show that innovation efforts that concentrate investments on software acquisition also generate negative results on innovation outputs our results shed light on critical aspects of innovation in the brazilian emergent economy that provide insights and contributions for both managers and policy makers

the role of innovation in bilateral oecd trade performance this paper tests an empirical model of the determinants of bilateral oecd trade with particular emphasis on the role of innovation variation in the relationship across countries and sectors is analysed two innovation proxies and actual data on innovations are used a positive relationship is found between relative innovation and bilateral trade performance at an aggregate level and for a number of manufacturing sectors sectors are also categorized as either net users or producers of innovations differences in innovation appear to have more of an impact on trade performance for the net producers of innovations than the net users of innovations

a technology gap approach to why growth rates differ abstract this paper contains a discussion and test of the technology gap approach to development and growth the basic hypotheses of the theory are tested on pooled cross sectional and time series data for 25 industrial countries for the period 1960 1983 the sample includes in addition to 19 oecd countries 6 of the most important industrial economies from the non oecd area the findings of the paper confirm that there exists a close correlation between the level of economic development measured as gdp per capita and the level of technological development measured through r d or patent statistics furthermore for the group of 25 countries as a whole technology gap models of economic growth are found to explain a large part of the actual differences in growth rates both between countries and periods as expected both the scope for imitation growth in innovative activity and efforts to narrow the gap investment appear as powerful explanatory factors of economic growth however when the non oecd countries and later usa and japan are removed from the sample the explanatory power of the technology variables especially growth in innovative activity diminishes

raw materials profits and the productivity slowdown a factor price frontier framework is used to clarify the analogy of an increase decrease in raw material prices with autonomous technological regress progress factor price profiles are estimated for the manufacturing sector of the united states the united kingdom germany and japan the production model in conjunction with estimates obtained from the factor price frontier attributes much of the slowdown in manufacturing productivity to the rise in relative raw material prices part of the apparent productivity riddle may have to do with the use of double deflated national accounting measures of value added which have an inherent measurement bias

the social shaping of the national science base abstract innovation studies confirm de tocqueville s prediction that continuous technical change in business firms in modern society would require the development in close proximity of publicly funded basic research and associated training the rate and direction of the development of a country s science base is strongly influenced by its level of economic development and the composition of its economic and social activities in other words it is socially shaped

federal acid rain games abstract federal environmental policy designed to control acid rain is shaped after the hierarchy of the system and is controlled simultaneously by regional and central governments each governmental level controls one of two policy instruments pollution abatement production and pollution tax in a two stage game where regional governments are stackelberg leaders and control pollution taxes the subgame perfect equilibrium is socially efficient but the subgame perfect equilibrium for a two stage game where the central government is the stackelberg leader and controls pollution taxes is inefficient it corresponds to the nash equilibrium for a game where regional governments control both policy instruments

research and development human capital and trade performance in technology intensive manufactures a cross country analysis abstract this paper comprises an extensive examination of the relationship between commonly utilized policy indicators of national technological capability and observed trade success in technology intensive manufactures across 52 countries in the 1980s a central focus is the relative performance of policy indicators which directly measure innovative activity such as patent output and expenditure and employed scientists and engineers in r d versus those measuring general efforts at increasing national levels of human capital the study design is guided by the inter country intrasectoral approach outlined by dosi et al 19 it emphasizes differences in trade performance based on the notion of international competitiveness but also compares results for conventional revealed comparative advantage indices the large number of countries included and the nature of the policy objectives adopted have necessitated a highly aggregated approach using nation wide attributes and trade in one broad technologyintensive sector as the measure of demonstrated international competitiveness simple correlation and multiple regression techniques are used to assess the association of four main sets of national attributes indicators of direct innovative activity general human capital development physical capital formation and natural resource endowment with technology intensive trade performance the empirical findings provide further support for the importance of national differences in technological capability as a determinant of structural and international competitiveness within the technology intensive sector of production they suggest that policy indicators measuring actual innovative activity and physical capital formation have a much closer link to technology intensive trade than the general educational effort or output indicators demand side measures which proxy the actual employment and application of resources for r d purposes demonstrate the strength of association required for reliable policy evaluation of real national differences in technological capability the poor performance of the general human capital supply variables highlights the need for a careful consideration of the optimality of the allocation of substantial levels of scarce national resources to broad based educational output a number of other significant results concerning the link between technology indicators technology intensive trade and economic performance are discussed

tax competition in a fiscal union with decentralized leadership this paper examines capital tax competition in the presence of an interstate transfer policy without federal commitment lack of commitment implies that local tax policy is chosen prior to federal transfers the paper s main result is that ex post federal policy neutralizes horizontal fiscal externalities insulating tax policy from capital mobility federal policy however introduces a new source of inefficiency unrelated to tax competition specifically ex post transfer payments prove to be equivalent to an interstate revenue sharing system which may render federal intervention in the presence of fiscal externalities welfare deteriorating relative to tax competition

the stock market and the productivity slowdown international evidence extending baily s model of the productivity slowdown to the manufacturing sectors of five other countries we find that a decline in the growth of capital services reflected in declines in the stock market can explain much of the 1973 1978 decline in productivity abroad as well as in the united states we also show however that the stock market declines often preceded the declines in productivity growth and the model is less successful when the sample period is extended through 1981

institutional rigidities and economic growth this paper involves a critical discussion of nicholas kaldor s contribution to the theory of economic growth and the associated verdoorn law as well as kaldor s theory prominent rival theories such as the diffusion hypothesis of s gomulka and the neo marxist model proposed by s bowles et al are found wanting an alternative approach is developed based on the nature and role of institutions in modern economies and their function in encapsulating or transmitting both codifiable and noncodifiable knowledge confirmation of this institutional theory of economic growth is provided by an econometric test using cross section oecd data copyright 1989 by oxford university press

large firms in the production of the world s technology an important case of non globalisation us patenting by 686 of the world s largest manufacturing firms shows that their share of the world s production of technology is less than their share of r d activities and varies greatly amongst sectors in most cases the technological activities of these large firms are concentrated in their home country the characteristics of which influence the volume and trends in their technological activities much more strongly then the international component of these activities at the same time these large firms are major elements in the volume and the pattern of sectoral specializations in their home countries technological activities

decentralized fiscal federalism revisited optimal income taxation and public goods under horizontal leadership this paper concerns optimal taxation and public goods in an economic federation with decentralized leadership where one lower level government is the first mover also in the horizontal dimension under plausible assumptions horizontal leadership reinforces the incentives created by decentralized leadership

smoothing income in anticipation of future earnings abstract recent theory argues that concern about job security creates an incentive for managers to smooth earnings in consideration of both current and future relative performance we find support for this theory our evidence suggests that when current earnings are poor and expected future earnings are good managers borrow earnings from the future for use in the current period conversely when current earnings are good and expected future earnings are poor managers save current earnings for possible use in the future however sensitivity analysis indicates that we cannot rule out selection bias as a potential alternative explanation for our findings

analyzing literature based innovation output indicators the italian experience abstract this paper presents the results of a study on the product innovations introduced in the italian market in 1989 and reported in a selected number of trade journals the analysis of data collected by means of this literature based counting procedure confirms that r d oriented industries and large firms do not in italy have a marked competitive advantage in innovation the country appears to be instead characterized by a significant presence of consumer goods industries and small firms in innovation our data indicate a statistically significant association between trade competitiveness and strength in product innovation and show the comparatively higher capacity for product innovation of some of the industries in which italy achieves a positive performance in international trade moreover the presence of spillovers at the regional level from both private and public r d expenditures proves to be positively correlated with the development of product innovations finally small firms with fewer than 50 employees appear to be more innovative than is usually believed to be the case

the catch up factor in postwar economic growth the catch up factor in postwar economic growth presidential address to the western economic association june 21 1989 i this talk is about two of the central concerns of our time one is the pronounced slowdown of productivity growth that has persisted in the whole of the industrialized world since the early seventies or late sixties about two decades the other is the much slower rate or productivity advance in the united states than in other industrialized countries than has been apparent during almost the whole postwar period about four decades 1 i shall argue that these two developments are connected and that both can be better understood if we think of them as implications of a process of international productivity catch up and convergence that is in certain conditions natural and foreseeable and in a long term sense desirable i mean desirable not only for the countries that are catching up that is obvious i mean desirable also for the old leader that is for the united states as well needless to say i do not contend that a tendency to convergence is the whole story behind the two developments and the anxieties they have caused but i believe it is a large part of it 1 ii let me begin by asking why and what conditions a tendency to convergence is as i say in the nature of things consider two countries otherwise similar but one is a productivity leader the other a laggard there are at least five reasons why the laggard will have a stronger potential for productivity growth than the leader first as the leader s capital stock turns over its embodied technological progress is limited by the advance of knowledge over the lifetime of its capital instruments but a laggard can make a larger leap by substituting modern state of the art equipment for instruments that were obsolete even when originally installed the same applies to modernization in disembodied technology that is when a laggard adopts a leader s advanced practices in the organization of production and management secondly laggards typically suffer from relatively low levels of capital intensity on this account as well as because new capital means a large technological leap the inducement to invest tends to be high so there is a potential for rapid progress by capital accumulation edward f denison 1967 table 21 28 robert e lipsey and irving b kravis 1987 edward n wolff 1987 table 31 thirdly the level of schooling in laggard countries is typically relatively low and in some degree obsolete in content so there is an opportunity for relatively rapid advance by the extension and modernization of education maddison 1982 table 5 7 denison 1967 table 21 28 fourthly in laggards one usually finds a relatively large fraction of partially or wholly redundant workers attached to farming and petty trade this is an opportunity for relatively large gains from the better allocation of workers denison 1967 table 21 28 fifthly the chance for rapid productivity advance along all these channels means a chance for rapid growth in aggregate output and size of markets which brings a productivity bonus from the economies of scale this is the simple core of the tendency to convergence and if that were all there was to it we should expect to see laggards always and everywhere advance faster than a leader rates of productivity growth across countries in any period would be an inverse function of their initial levels of productivity and national levels of productivity would converge towards the leader s by the same token as the process of convergence went on the gaps separating laggards from leaders would become smaller and rates of growth would decline the catch up effect supporting growth would be self limiting weakening steadily as catch up proceeded

optimum taxation with errors in administration abstract the paper compares the welfare levels which can be achieved by two distinct tax regimes lump sum taxation where one attempts to identify individuals and allocate transfers or subsidies on the basis of characteristics and income taxation where characteristics are not observed but personal incomes are measured and taxed where there are no errors in classifying individuals lump sum taxation is superior but where mistakes are made in the allocation of lump sum grants or subsidies income taxation may be more attractive the level of errors where the regimes are equally desirable in terms of social welfare is computed in simple models following that of feldstein 1973 where there is strong aversion to inequality then income taxation becomes preferable at quite small errors in analysing income taxation it is shown that in the feldstein model with endogenous wages the marginal tax rate in optimum income taxation on the more skilled is negative and that on the less skilled is positive in contrast to the standard results see seade 1977 with exogenous wages

productivity and cost gaps in manufacturing industries in u s japan and germany abstract the objective of this paper is to measure and explain the development of differences in productivity for five manufacturing industries of the u s japan and germany changes in total factor productivities and differences in technologies and the sources of those changes will be analyzed we extend the framework developed by jorgenson and nishimizu 1978 to the dual cost approach to reflect the efficiency aspect of productivity gaps in terms of cost disadvantages we employ translog cost functions for a description of productivity and cost efficiency gaps and for an econometric analysis of sources of catching up processes

the productivity slowdown the oil shocks and the real cycle f ive facts stand out about economic performance in the united states since world war ii the first is that for most of the postwar period the u s has had a slower rate of economic growth than the other major developed democracies except great britain and much lower rates of growth than germany japan and italy the gap between the growth of per capita income of the united states and comparable countries has however tended to diminish over time and the united states has lately grown at about the same rate as most other developed countries the second outstanding fact is that the united states has fallen far behind in many mass production industries in which it used to lead the world whereas it is ahead of other nations in many new and especially high technology industries in automobiles steel tires household appliances and earth moving and farm equipment for example u s production has fallen dramatically in relation to output in most comparable countries and the country has become a net importer of most such products by contrast in newer industries such as computers jet aircraft sophisticated weaponry and high technology in general the united states is often dominant both as producer and exporter the third outstanding fact is that most of the older heartland of american industry roughly the area north and east of an arc drawn from baltimore to st louis to milwaukee has declined dramatically in comparison with the south and the west this change in regional fortunes has been due in large part to migration motivated by differences in economic prospects from the declining to the advancing

self selection and pareto efficient taxation abstract this paper analyses the set of pareto efficient tax structures the formulation of the problem as one of self selection not only shows more clearly the similarity between this problem and a number of other problems such as the optimal pricing of a monopolist which have recently been the subject of extensive research but also allows the derivation of a number of new results we establish i under fairly weak conditions randomization of tax structures is desirable ii if different individuals are not perfect substitutes for one another in production then the general equilibrium effects until now largely ignored in the literature of changes in the tax structure may be dominant in determining the optimal tax structure in particular if the relative wage of high ability and low ability individuals depends on the relative supplies of labor the optimal tax structure entails a negative marginal tax rate on the high ability individuals and a positive marginal tax rate on the low ability individuals the marnitude of which depends on the elasticity of substitution iii if individuals differ in their preferences pareto efficient taxation may entail negative marginal tax rates for high incomes while iv if wage income is stochastic the marginal tax rate at the upper end may be 100 our analysis thus makes clear that the main qualitative properties of the optimal tax structure to which earlier studies called attention are not robust to these attempts to make the theory more realistic
