the macroeconomic effect of import controls a keynesian analysis abstract this paper develops a keynesian analysis of import controls a simple multiplier model is first presented which captures the two basic effects of controls identified by keynesian and disequilibrium theories forced import substitution and involuntary disabsorption the analysis is then extended to include some intertemporal and fiscal effects later sections develop a more complex model in which the market for goods and services is considered together with the effects of controls on the supply and demand for money and on the black market for foreign exchange

regional innovation systems theory empirics and policy asheim b t lawton smith h and oughton c regional innovation systems theory empirics and policy regional studies interest in regional innovation systems has grown significantly over the past three decades driven partly by advances in theoretical analysis partly by the growing interest in innovation as a source of competitive advantage and partly by the need for new policies to address regional inequalities and divergence this article explores the elements and characteristics that exemplify the regional innovation systems approach it provides an appraisal and synthesis of the regional innovation systems paradigm and aims to shed light on a number of areas where theoretical empirical and policy based questions remain unanswered it outlines and assesses the major strands in recent theoretical and empirical debates and discusses how they might be developed to contribute to the further advancement of the regional innovation systems literature three interrelated questions form the key themes arou

phillips curves in developing countries the latin american case one of the more controversial subjects in macroeconomics during the last 2 decades has derived from the finding of phillips 1958 and subsequently numerous others of a stable empirical relationship between the rate of wage or price changes and the rate of unemployment or output growth the original contention has been increasingly challenged on the grounds that 1 its rationale is at best ambiguous 2 the relationship is unstable and 3 it is only a short run relationship nevertheless the significance of the subject has been preserved by its continued importance for policy by friedman s claim that the phillips curve relationship plays the important role of the missing equation distinguishing his own quantity theory of money oriented macro theory from the keynesian theory 2 and by the fact that recent more sophisticated empirical studies recognizing both supply and demand sides to output determination 3 tend to support it at least in the short run

territorial innovation models a critical survey moulaert f and sekia f 2003 territorial innovation models a critical survey reg studies 37 289 302 this paper provides a critical review of the literature on territorial innovation models industrial districts milieux innovateurs new industrial spaces local production systems etc the review is organized in two stages first the main features of each of these models and their view of innovation are compared second their theoretical building blocks are reconstructed and evaluated from the point of view of conceptual clarity and analytical coherence it is found that despite some semantic unity among the concepts used economies of agglomeration endogenous development systems of innovation evolution and learning network organization and governance territorial innovation models tims suffer from conceptual ambiguity the latter is mainly a consequence of the way territorial innovation is theorized i e in terms of technologically driven innovation and a business culture that is ma

getting deals done the use of social networks in bank decision making economic actors confront various forms of uncertainty making decisions and how they deal with these obstacles may affect their success in accomplishing their goals this study examines the means by which relationship managers in a major commercial bank attempt to close transactions with their corporate customers it is hypothesized that under conditions of high uncertainty bankers will rely on colleagues with whom they are strongly tied for advice on and support of their deals drawing on recent network theory it is also hypothesized that transactions in which bankers use relatively sparse approval networks are more likely to successfully close than are transactions involving dense approval networks both hypotheses are supported bankers are faced with a strategic paradox their tendency to rely on those they trust in dealing with uncertainty creates conditions that render deals less likely to be closed successfully this paradox represents an example of unanticipated consequences of purposive social action

a comparison of the dynamics of industrial clustering in computing and biotechnology abstract this paper compares the dynamics of the process by which industrial clusters emerged in the us computing and biotechnology industries it examines whether new companies are attracted by industry strength in particular sectors or by the strength of the science base at particular locations in biotechnology it also compares the growth of incumbent firms in the two industries and asks whether growth is boosted by being within a cluster the paper finds that within computing there are some important cross sectoral effects on entry while in biotechnology these cross sectoral effects are more limited in biotechnology the science base plays an important role in promoting entry the growth of incumbent firms in both industries is promoted by strength in the company s own sector and cross sectoral effects and the role of the science base are negligible

local demand pull policy and energy innovation evidence from the solar photovoltaic market in china abstract market demand is an important driver for inducing innovation with many empirical studies supporting the demand induced innovation hypothesis critiques of such studies however emphasize that new empirical evidence that can address existing empirical challenges is needed furthermore existing literature disagrees about whether the locus of demand pull policy matters in this paper we use empirical evidence from the distributed solar photovoltaic pv market in china to address the following questions 1 is there evidence of demand induced innovation 2 does the effect of local demand pull policy differ from the effect of non local demand pull policy on demand induced innovation to address these questions we develop and analyze an original database of pv balance of system bos patents in the distributed pv market filed between 2005 and 2014 in china our results support the demand induced innovation hypothesis and suggest that only local demand significantly induces pv bos innovations in the distributed pv market in china the different effects of local demand and non local demand emphasize the importance of local markets and local policies lending some support to bottom up approaches to clean energy governance

the rise and persistence of rigidities in this paper we argue that employment protection legislation is more likely to arise when the rents earned by the employed over their alternative wage is greater the model explains why economies with greater real wage rigidity also have greater employment protection the model also predicts that lower turnover increases the political support for employment protection and that this political support is greater when employment protection is more harmful for employment also rigidities are persistent as they create a constituency of low productivity sectors whose workers would oppose the removal of firing costs even though existing rents would not generate support for introducing them we argue that tight labour markets due to post war reconstruction needs in europe made it easier for insiders to create such rents which in turn led them to support employment protection legislation in the late 1970s rents started to fall but reforms proved difficult because of ratchet effects this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item

eu regions and multinational corporations change stability and strengthening of technological comparative advantages in a rapidly globalizing economy and particularly in the face of a process of economic integration such as that occurring in the eu regions forge an increasing number of linkages with other locations within and across national boundaries through the local technological development efforts of multinational corporations mncs by using a database of patents granted to the largest firms by the us patent and trademark office uspto we have shown in previous research that the pattern of mnc networks for innovation conforms to an internal within national boundaries hierarchy of regional centres in this paper the hypothesis of the combined significance of cumulativeness and incremental change in innovation is examined by testing the extent of continuity in the sectoral composition of technological profiles of different eu regional centres between the 1970s and the 1990s the results provide support for our hypothesis that a geographical hierarchy of regional locations can be established also across national boundaries within the eu it is shown that the core european regions can be divided into two kinds those in which mncs have consolidated areas of traditional specialisation for the regions in question and those in which there has been a shift towards and a relative growth of the development of fields of high technological opportunities

information and structural holes comment on reagans and zuckerman reagans and zuckerman hereafter rz go behind the performance link with network brokerage to speculate on how information flow is responsible the intuition is a perceived tension between brokers and contacts if nonredundant sources of information provide the broker s competitive advantage as is assumed in empirical research on the returns to brokerage then the broker s contacts have a countervailing advantage as monopoly sources advantage versus countervailing advantage is the tension to be resolved the analysis is interesting in its own right but it carries a broader significance in addressing a critical juncture for network models of advantage empirical success in predicting performance with network models has far outstripped our understanding of the way information flow in networks is responsible for network effects a cluster of network concepts emerged in the 1970s on the idea that advantage results from connections with multiple otherwise disconnected groups and individuals the hubs in a social network were argued to have advantaged access to information and control over its distribution at the center of the concept cluster are granovetter 1973 1983 on weak ties as bridges between groups freeman 1977 1979 on network centrality as a function of being the connection between otherwise disconnected people cook and emerson 1978 cook et al 1983 on the advantage of having alternative

is western europe losing the technological race abstract using a variety of indicators this paper compares technological levels in japan the usa and w europe there is no justification for assuming general european technological backwardness whilst it lags in electronics and since 1975 has had a relatively slow rate of growth of innovative activities it also has sectors of strength chemicals machinery production engineering and countries whose relative commitments of resources to innovative activities are at least equal and sometimes superior to those of japan and the usa frg sweden switzerland its main policy challenges are to increase the rate of growth of innovative activities in lagging countries and to ensure pervasive applications of information technology similarly there is no convincing evidence that w europe is relatively backward in converting technology into economically efficient innovations some policy problems are significant in all three regions skill shortages whilst others are in the usa and w europe short term planning horizons of top management particular european problems are the effects of social legislation on worker flexibility and mobility of national regulations on intra european competition and of slow rates of growth of output on the growth of innovative activities japan and the usa have their problems with the latter continuously under challenge from the former and increasingly specialised in defence and raw materials related technologies

localised production of technology for global markets given the trends towards increasing globalization of markets and of production the globalization of technology remains a subject of considerable interest to analysts and policymakers in the 1990s the main conclusion of this paper is that there is no systematic evidence to suggest that widespread globalization of technological activities occurred in the 1980s the evidence based on the u s patenting activities of 569 of the world s largest firms based in 13 countries and covering 17 product groups shows that for an overwhelming majority of them technology production remains close to the home base the analysis also shows the dangers of generalizing on the basis of anecdotal evidence from a small sample of firms from a particular country or sector c 1995 academic press inc copyright 1995 by oxford university press

dynamics of networks if everyone strives for structural holes when entrepreneurs enter structural holes in networks they can exploit the related benefits evidence for these benefits has steadily accumulated the authors ask whether those who strive for such structural advantages can maintain them if others follow their example burt speculates that they cannot but a formal demonstration of this speculation is lacking using a game theoretic model of network formation the authors characterize the networks that emerge when everyone strives for structural holes they find that the predominant stable networks distribute benefits evenly confirming that no one is able to maintain a structural advantage in the long run

inflation and imported input prices in some inflationary latin american economies this paper first updates to 1980 the estimates of the harberger inflation model for argentina brazil chile colombia and uruguay and shows that all the hypotheses of this model hold and the reaction to monetary growth is fairly rapid an aggregate supply function including imported inputs is then hypothesized following recent theoretical work this yields two testable propositions on the reduced form estimates of inflation a the relation between inflation and monetary growth should be less than proportional and the income coefficient should be insignificant contrary to the harberger model and b inflation should be a weighted average of monetary growth and imported inflation assuming the underlying aggregate production function is homogenous of degree zero in prices tests on the same data base support both hypotheses these results also explain the similar results of many of the previous estimates of the harberger inflation equation which included the rate of devaluation in an ad hoc fashion

moral hazard and nonmarket institutions dysfunctional crowding out or peer monitoring the authors examine a situation in which insurance is characterized by moral hazard when market insurance is provided supplementary mutual assistance between family and friends unobservable to market insurers will occur when nonmarket insurers have no better information than market insurers the mutual assistance not only crowds out market insurance but is also harmful and therefore dysfunctional alternatively when nonmarket insurers can observe each other s effort perfectly mutual assistance is beneficial these results point to the potential importance of peer monitoring mechanisms in mitigating moral hazard copyright 1991 by american economic association

import controls prices and economic activity in colombia abstract this paper analyzes the effects of import controls on production and price formation in the colombian manufacturing sector in 1976 1987 for that purpose it presents and estimates a simple model of imperfect competition which captures the quantity and price effects of qrs the statistical results support the idea that direct import controls have strong quantity and weak price effects the former concentrate in a few sectors particularly machinery and equipment most of which are not sensible to relative import prices however even in sectors where qrs have weak direct quantity effects indirect effects of import policy may be important given the sensitivity of industrial production to aggregate demand

a theory of buyer seller networks this paper introduces a new model of exchange networks rather than markets of buyers and sellers it begins with the empirically motivated premise that a buyer and seller must have a relationship a link to exchange goods networks buyers sellers and the pattern of links connecting them are common exchange environments this paper develops a methodology to study network structures and explains why agents may form networks in a model that captures characteristics of a variety of industries the paper shows that buyers and sellers acting strategically in their own self interests can form the network structures that maximize overall welfare

an evolutionary approach to understanding international business activity the co evolution of mnes and the institutional environment this paper examines the co evolution of mne activities and institutions external and internal to the firm we develop a theoretical framework for this analysis that draws on the more recent writings of douglass north on institutions as a response to complex forms of uncertainty associated with the rise in global economic interconnectedness and of richard nelson on the co evolution of technology and institutions we link historical changes in the character of mne activities to changes in the institutional environment and highlight the scope for firm level creativity and institutional entrepreneurship that may lead to co evolution with the environment we argue that the main drivers for institutional entrepreneurship are now found in the increasing autonomy of mne subsidiaries thus mne agency derives from more decentralized forms of experimentation in international corporate networks which competence creating nodes of new initiatives can co evolve with local institutions unlike most other streams of related literature our approach connects patterns of institutional change in wider business systems with more micro processes of variety generation and experimentation within and across individual firms this form of co evolutionary analysis is increasingly important to understanding the interrelationships between mne activities and public policy

the globalisation of technology what remains of the product cycle model this paper reexamines two hypotheses associated with earlier versions of the product cycle model the first hypothesis that innovations are almost always located in the home country of the parent company is rejected on the basis of evidence drawn from one hundred years of u s patent office data the second hypothesis that the international dispersion of activity is led by technology leaders is historically valid however over the last twenty years technology leaders have been ahead instead in the globalization of technology that is in developing internal international networks to exploit the locationally differentiated potential of foreign centers of excellence c 1995 academic press inc copyright 1995 by oxford university press

the policy implications of the globalisation of innovation abstract the paper develops a taxonomy of the globalisation of innovation based on three categories a the international exploitation of technology produced on a national basis b the global generation of innovations c the global technological collaborations the most evident changes implied by the increasing globalisation of innovation and technology are the tougher and increased competition and the greater collaboration between actors both across and within national boundaries the advantages just as the costs of these tendencies can be substantial leading to a higher risk of winners and losers the paper analyses the different impact that each category might have on the economic and innovative performance of countries and regions with the aim of defining the implications for national policies it is suggested that public policies play a different role in each of the three processes of the globalisation of innovation and that a single strategy does not exist neither from a firm s nor from a government s perspective the paper emphasis that none of the three categories in this taxonomy renders national policy obsolete on the contrary public policies are necessary on a far wider range than those currently implemented in the majority of countries

job assignments signalling and efficiency this article analyzes a model in which information about a worker s ability is only directly revealed to the firm employing the worker other firms however use the worker s job assignment as a signal of ability three results recur throughout the analysis first wage rates tend to be more closely associated with jobs than with ability levels second there is frequently an inefficient assignment of workers to jobs i e even when a firm has complete information about a worker s output third the severity of this inefficiency tends to be negatively correlated with the level of firm specific human capital in the economy

determinants of the internationalization of regions the role and effectiveness of public policy measures banno m piscitello l and varum c determinants of the internationalization of regions the role and effectiveness of public policy measures regional studies this paper assesses the role of public policy measures on outward internationalization of regions by including financial and non financial incentives among the determinants of the international competitiveness of regions it is found that the former are important to enhance their active internationalization but that variables related to the knowledge and competence base of regions are even more so financial incentives related to equity participation as well as non financial incentives related to the provision of information come out highly significant in stimulating outward internationalization the empirical analysis is conducted for the twenty italian nuts 2 regions over the period 2003 2008

economic integration and political disintegration in a world of trade restrictions large countries enjoy economic benefits because political boundaries determine the size of the market under free trade and global markets even relatively small cultural linguistic or ethnic groups can benefit from forming small homogeneous political jurisdictions this paper provides a formal model of the relationship between openness and the equilibrium number and size of countries and successfully tests two implications of the model firstly the economic benefits of country size are mediated by the degree of openness to trade secondly the history of nation state creations and secessions is influenced by the trade regime

technological internationalisation in the electro technical industry a cross company comparison of patenting patterns 1986 2000 abstract this paper addresses the issue of r d internationalisation of two multinationals in the electro technical industry ge and abb by means of a patent data analysis the overwhelming majority of both companies r d activities are concentrated in western europe and north america the locational overlap between the two firms activities is small these results are consistent with findings from earlier studies that 1 there is little evidence to suggest that the production of technology is globalised in a general sense and 2 that tapping knowledge from an industry s global lead location plays a very limited role in foreign r d investments

developing innovative competences the role of institutional frameworks the recent development of the biotechnology and computer industries has highlighted the variety of ways in which firms in different countries and sectors can develop innovative competences four aspects are particularly important the degree of involvement in the public science system involvement in industry collaborations reliance on specialist skills of individuals and the ability to change collective competences radically national and regional variations in these result from differences in dominant institutional frameworks in addition to the organization of capital and labour markets and the structure of inter firm relations these frameworks include the nature of the public science system particularly important features of these systems include the organization of research training the flexibility of researchers and organizations in developing novel goals and approaches the organization of scientific careers and the prevalent science and technology policies of the state distinct combinations of these institutional features have become established in different market economies and led to contrasting styles of innovative competence development being adopted these in turn help to explain continuing variations in patterns of technological change between countries

inflation growth and import bottlenecks in the turkish manufacturing industry abstract this paper argues that in economies heavily dependent on imported inputs the responsiveness of price and output to cost and demand factors are altered by foreign exchange bottlenecks if the government resorts to non market allocation of import licenses a model of price and output determination which captures this stipulation is presented estimation results for the turkish manufacturing industry over the 1952 1980 periods support the hypothesis that price and output elasticities are different between the import crisis and non crisis periods most importantly monetary expansion is inflationary when there are important bottlenecks but has real output effects otherwise

export specialisation and local economic growth this paper aims to provide empirical evidence on whether export specialization or diversification is better for local economic growth using export data from 354 magisterial districts of south africa for 1996 and 2001 we estimate spatial growth regressions that include measures of the degree of export specialization and diversification overall exporting regions outperform other less or non exporting regions also we find that export specialisation rather than export diversification has been associated with local economic growth with specialization in mining and agriculture being especially beneficial our results support the view that specialization in a locality s area of comparative advantage is good for local economic development we also find that localities with higher initial levels of human capital and higher subsequent population growth performed better this is consistent with the belief that policies aimed at strengthening human capital and improving agglomeration economies will enhance local economic development

specialization and size of technological activities in industrial countries the analysis of patent data abstract the determinants and direction of the technological specialization of advanced countries are investigated in this paper using patent counts and citations as technology indicators during the 1980s international patenting increased more rapidly than the resources devoted to r d indicating a globalization of technology markets paralleled by a growing degree of sectoral specialization of countries innovative activities a clear cut inverse relationship between countries technological size measured by cumulative r d expenditure and degree of specialization has been found only large countries can afford to spread their activities across most technological fields while small and medium sized countries are to some extent forced to specialize in more narrow niches some methodological aspects in the use of patenting as an internationally comparable indicator are also discussed considerable differences emerged between patent specialization profiles in the internal and in external markets firms tend to protect their internal market through patenting also in fields where they do not excel at the international level leading to a smoother specialization profile

accumulating technological competence its changing impact on corporate diversification and internationalization recent studies have suggested that firm specific technological competence may be diversified and internationalized we show that increases in competence increased corporate technological diversification until the early 1970s and then again more recently however a new interrelationship has now emerged between the accumulation diversification and internationalization of technological competence due to the formation of internationally integrated networks within firms the empirical analysis consists of a dynamic cross section model applied to the corporate patenting in the us of 166 of the largest european and us industrial firms from 1901 to 1995 copyright 2000 by oxford university press

the narrow moving band the dutch disease and the competitive consequences of mrs thatcher notes on trade in the presence of dynamic scale economies abstract this paper presents a model of trade in which comparative advantage instead of being determined by underlying attributes of countries evolves over time through learning by doing in this model arbitrary patterns of specialization once established tend to become entrenched over time the model sheds light on three widely held views that do not make sense in more conventional models first is the view that temporary protection of selected sectors can permanently alter the pattern of comparative advantage in the protecting country s favor second is the view that seemingly favorable developments such as the discovery of exportable natural resources may lead to a permanent loss of other sectors and reduce welfare in the long run third is the possibility that a temporary overvaluation of a currency due to tight money can lead to a permanent loss of competitiveness in some sectors

investment and technical progress models in which the growth rate is exogenous provide no role for government in determining growth in our model growth is associated with investment through externalities from learning by watching rather than with the level of the capital stock presumption of a technical progress function with first increasing and then decreasing returns leads to multiple steady state growth equilibria there is also an explicit role of government policy in setting tax rates on output it follows that two economies with identical structures and stochastic tax policies may exhibit very different growth paths over sustained periods although the stationary distribution of growth rates is the same given the desirability in principle of subsidizing investment various practical methods are considered copyright 1992 by oxford university press

brokers and competitive advantage the broker profits by intermediating between two or more parties using a biform game we examine whether such a position can confer a competitive advantage as well as whether any such advantage could persist if actors formed relations strategically our analysis reveals that if one considers exogenous the relations between actors brokers can enjoy an advantage but only if 1 they do not face substitutes either for the connections they offer or the value they can create 2 they intermediate more than two parties and 3 interdependence does not lock them into a particular pattern of exchange if on the other hand one allows actors to form relations on the basis of their expectations of the future value of those relations then profitable positions of intermediation only arise under strict assumptions of unilateral action we discuss the implications of our analysis for firm strategy and empirical research

a macroeconomic analysis of agricultural terms of trade in turkey 1952 90 a two sector model of terms of trade tot determination is developed and tested using time series data for turkey empirical results support the structuralist flex price agriculture fix price industry models tot is found to be sensitive to changes in nominal demand and the exchange rate rising nominal demand turns the tot in favour of the agricultural sector provided that there are no supply constraints in the industrial sector if industrial supply is constrained by import bottlenecks then aggregate demand expansion turns the tot in favour of the industrial sector devaluation turns the tot against the agricultural sector primarily via the cost push factors in the industrial sector

job contact networks abstract many workers hear about or obtain their jobs through friends and relatives the aim of this paper is twofold first we relate both individual and aggregate labor market outcomes to the network structure of personal contacts second we study strategic network formation to this purpose we develop a model specifying at the individual level both the decision to form contacts with other agents and the process by which information about jobs is obtained and transmitted we show that equilibrium networks always exist and that only moderate levels of network asymmetry can be sustained at equilibrium also we establish a general non monotonicity result on information flow and unemployment with respect to network size in symmetric networks

historical evolution of technological diversification a positive relationship exists between national technological size and technological diversification across fields of innovative activity this paper shows how the nature of this relationship has changed historically there has been a downward structural shift in the cross country size diversification frontier since 1965 for any given size countries have become less diversified or more narrowly concentrated in their technological specialisation one explanation is that international technology sourcing by mnes has led locations to focus on what they do best a supporting factor may be a rise in technological interrelatedness which encourages focus upon a specific selection of complementary combinations

structural holes in social networks we consider a setting where every pair of players that undertake a transaction e g exchange goods or information creates a unit surplus a transaction can take place only if the players involved have a connection if the connection is direct the two players split the surplus equally while if it is indirect then intermediate players also get an equal share of the surplus thus individuals form links with others to create surplus to gain intermediation rents and to circumvent others who are trying to become intermediary our analysis clarifies the interplay between these forces in the process of strategic network formation first we show that in the absence of capacity constraints on links it leads to the emergence of a star network where a single agent acts as an intermediary for all transactions and enjoys significantly higher payoffs second we study the implications of capacity constraints in the ability of agents to form links in this case distances between players must be long which induces players who are far off to connect in order to avoid paying large intermediation rents a cycle network then emerges payoffs being equal across all players

geographical amplitude in the international generation of technology present situation and business determinants abstract building on a rich dataset with information on 65 000 firms and 465 000 european patent applications from 1978 to 2000 this paper addresses the geographical amplitude of international technology generation first we show that the number of countries hosting international technological activities is increasing the usa and some developing nations benefit from this internationalisation conversely although europe as a whole still plays a leading role in the encouragement of foreign technological activities some european countries such as germany and the uk appear to be losing their technological appeal second we verify that multinational corporations mncs have increased the geographical amplitude of their technological activities in fact the mean number of countries in which mncs internationalised technology generation has doubled during the 23 years we have analyzed third we address the business characteristics that explain this phenomenon a negative binomial regression suggests that internationalisation is higher in mncs showing a greater technological diversification a higher volume of technological activity a wider presence in international markets and more experience in the international generation of technology finally american corporations and regardless of the home country those firms whose main technological fields are in chemistry pharmaceuticals or electronics present the highest geographical dispersion of their international technological activities

the national system of innovation in historical perspective contrary to some recent work on so called globalisation this paper argues that national and regional systems of innovation remain an essential domain of economic analysis their importance derives from the networks of relationships which are necessary for any firm to innovate whilst external international connections are certainly of growing importance the influence of the national education system industrial relations technical and scientific institutions government policies cul tural traditions and many other national institutions is fundamental the historical examples of germany japan and the former ussr illustrate this point as well as the more recent contrast between east asian and latin american countries introduction the national system of friedrich list according to this author s recollections the first person to use the expression national system of innovation was bengt ake lundvall and he is also the editor of a highly original and thought provoking book 1992 on this subject however as he and his colleagues would be the first to agree and as lundvall himself points out the idea actually goes back at least to friedrich list s conception of the national system of political economy 1841 which might just as well have been called the national system of innovation the main concern of list was with the problem of germany overtaking england and for underdeveloped countries as germany then was in relation to england he advocated not only protection of infant industries but a broad range of policies designed to accelerate or to make possible industrialisation and economic growth most of these policies were concerned with learning about new technology and applying it the racialist and colonialist overtones of the book were in strong contrast to the inter nationalist cosmopolitan approach of the classical free trade economists and list s belief that holland and denmark should join the german bund and acquire german nationality because of their descent and whole character reads somewhat strangely in the european community of today nevertheless despite these unattractive features of his outlook he clearly anticipated many contemporary theories after reviewing the changing ideas of economists about development in the years since the second world war the world bank 1991 concludes that it is intangible investment in knowledge accumulation which is decisive rather than physical capital investment as was at one time believed pages 33 35 the report cites the new growth theory

a strategic model of social and economic networks we study the stability and efficiency of social and economic networks when self interested individuals can form or sever links first for two stylized models we characterize the stable and efficient networks there does not always exist a stable network that is efficient next we show that this tension persists generally to assure that there exists a stable network that is efficient one is forced to allocate resources to nodes that are not responsible for any of the production we characterize one such allocation rule the equal split rule and another rule that arises naturally from bargaining of the players

sectoral systems of innovation and production the concept sectoral system of innovation and production provides a multidimensional integrated and dynamic view of sectors it is proposed that a sectoral system is a set of products and the set of agents carrying out market and non market interactions for the creation production and sale of those products a sectoral systems has a specific knowledge base technologies inputs and demand agents are individuals and organizations at various levels of aggregation they interact through processes of communication exchange co operation competition and command and these interactions are shaped by institutions a sectoral system undergoes change and transformation through the co evolution of its various elements 2002 elsevier science b v all rights reserved

does host market regulation induce cross border environmental innovation this paper evaluates the effect of host country environmental policy stringency on the offshoring of environmental patents for 2000 top world r d performers it is shown that a more stringent environmental regulation triggers both the extensive and intensive margin of patent offshoring in the field of environmental technologies results are robust to various different specifications alternative definitions of innovation offshoring and of regulation restrictions and to the consideration of possible endogeneity of regulation it is suggested inter alia that r d subsidies and non market based regulatory measures are more important than market based instruments as drivers of cross border environmental innovation length 26 pages

location and the multinational enterprise in the early development of the international business field the focus of attention moved from the country level to the firm level and interest in location issues declined more recently firm based research has itself become increasingly concerned with the study of firm location interactions when examining two way knowledge flows or spillovers between multinational enterprises mnes and other actors in specific locations the diversity or heterogeneity of firms matters as does the diversity of locational environments the localization of knowledge sources depends on mne group level strategies for growth and organizational decentralization on subsidiary level evolution towards local competence creating efforts and on the development of suitable business networks within locations mnes now have a greater potential to benefit from a synergistic locational portfolio of complementary sources of knowledge the locational composition of the international network for knowledge sourcing of a given mne depends upon the extent of institutional compatibility between the locations in which the mne is active this compatibility between locations in turn affects the capacity of the mne to become an insider in local business systems and to influence the local institutional environment

the drivers of foreign direct investment into research and development an empirical investigation this paper examines the determinants of foreign direct investment fdi in research and development laboratories by 32 multinational enterprises in the pharmaceutical and electronics industries the paper applies a dichotomous set of motives for fdi results from an econometric analysis of 136 laboratory investments show that relative market size and relative strength of a country s science base determine whether fdi in research and development is carried out in order to exploit existing firm specific advantages or in order to build up new firm specific advantages this holds true in similar form for japanese european and u s firms and across the two industries

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

decentralised r d and strategic competitiveness globalised approaches to generation and use of technology in multinational enterprises mnes abstract using material from surveys of multinational enterprise mne production subsidiaries and laboratories operating in the uk the paper seeks to discern vital changes in the roles of such r d facilities from the primarily tactical and technologically dependent role of adapting established group products for the local market these labs now take more committed positions in support of their group s strategic competitiveness this can involve a much more profound involvement in original product development or inputs into programmes of pre competitive basic or applied research to support the longer term evolution of the core technology of the mne group it is suggested that this evolution of decentralised labs positioning in mne knowledge strategies implies i an increasing involvement in product development rather than adaptation ii an interdependent rather than dependent position in group technology programmes iii increased relevance of supply side influences host country technology competencies capacities and heritage iv decline of centralising forces on r d e g economies of scale communication and co ordination problems concerns of knowledge security

the changing landscape of jibs authorship in this study we examine the landscape of jibs authorship over time to assess 1 the accessibility of jibs to new contributors and 2 the diversity of authors contributing to jibs our analysis of author data from 1972 to 2014 shows that jibs is becoming more accessible as indicated by the high and sustained proportion of first time contributors to the journal this is also evident from the recent decline in the share of authors with multiple past jibs publications with regard to diversity our findings show that jibs has a much wider geographic scope of authors on its landscape in comparison to previous decades this may be attributed partly to increasing travel and communication in scholarly communities and partly to the increased migration of scholars in the recent decades our analysis of migration patterns of jibs authors suggests that about 51 of prominent international business scholars are employed outside their country of birth of the 49 employed in their country of birth 12 are return migrants in our sample china south korea and canada have the highest number of returnees the usa the uk germany the netherlands and china have the highest number of natives whose country of birth country of phd granting institution and country of university affiliation are identical

the formation of a core periphery structure in heterogeneous financial networks recent empirical evidence suggests that nancial networks exhibit a core periphery network structure this paper aims at giving an economic explanation for the emergence of such a structure using network formation theory focusing on intermediation benets we nd that a core periphery network cannot be unilaterally stable when agents are homogeneous the best response dynamics converge to a unique unilaterally stable outcome ranging from an empty to denser networks as the costs of linking decrease a core periphery network structure can form endogenously however if we allow for heterogeneity among agents in size we show that our model can reproduce the observed core periphery structure in the dutch interbank market for reasonable parameter values

the economics of technical change this paper reviews the recent rapidly growing literature on technical change in the economy it concentrates on innovations and their diffusion at firm and industry level since this was the area designated as relatively weak in earlier literature surveys the review argues that the extensive empirical evidence and theoretical analysis now available presents a basic challenge to neoclassical theory after indicating some weaknesses in the neo schumpeterian literature the paper concludes by advocating an experiment with a new form of assessment by neighboring disciplines to economics itself which would take full account of the fundamental issues at stake in this modern methodenstreit c 1994 academic press inc copyright 1994 by oxford university press
