infrastructure investment the cost of capital and regulation an assessment the paper considers the role of infrastructure in improving economic performance and its compar ative neglect relative to traditional macroeconomic and microeconomic policies it explains why infrastructure matters why britain s infrastructure performance has been poor and summarizes the scale of the challenge for the coming decade privatization liberalization and competition have focused on monopoly market failure and private incentives but they have neglected the time inconsistency problem which confronts investors in networks with high fixed and sunk costs the failure to commit which has characterized british approaches to infrastructure has been partially addressed through the creation of regulated asset bases rabs backed up by the duty on regulators to ensure that functions can be financed the paper considers how the rabs can be developed to provide credible long term contracts over a wide range of activities and how the financial regu latory regime can complement this commitment notably through the split cost of capital and the indexation of the cost of debt approaches the paper concludes by setting out the building blocks of a credible regulatory framework for infrastructure together with the impacts on reducing the cost of capital the role of the state in reinforcing this commitment and the associated institutions are also set out

the sustainable borders of the state economic crises have historically set the stage for the reconfiguration of the economic borders of the state current concerns focus on debt and associated intergenerational issues such as pensions infrastructure and the environment the sustainable state is designed to put in place a framework for integrating these intergenerational issues alongside the traditional focus on macroeconomic policy static market failures and transfers the building blocks include the accounting framework and in particular a national balance sheet setting out assets and liabilities and providing for capital maintenance over time to support these assets and to provide for sufficient investment the sustainable state requires an appropriate level of savings and institutions to translate these savings into investments two components are the deployment of regulatory asset bases to underpin long term sunk and fixed costs given the time inconsistency problem in government s commitments and the development of financial intermediaries such as an infrastructure bank copyright 2011 oxford university press

aggregation of information in large cournot markets consider a homogeneous product market where firms have private information about an uncertain demand parameter and compete in quantities we examine the convergence properties of bayesian cournot equilibria as the economy is replicated and conclude that large cournot or almost competitive markets do not aggregate information efficiently except possibly when the production technology exhibits constant returns to scale even in a competitive market there is a welfare loss with respect to the first best outcome due to incomplete information in general nevertheless a competitive market is efficient taking as given the decentralized private information structure of the economy endogenous and costly information acquisition is examined and seen to imply that the market outcome always falls short of the first best level with decreasing returns to scale the results are also shown to be robust to the addition of extra rounds of competition which allows firms to use the information revealed by past prices explicit closed form solutions yielding comparative static results are obtained for models characterized by quadratic payoffs and affine information structures

the assessment financial innovation curse or blessing as financial services go through one of their most radical restructurings of this century this as sessment analyses the factors underlying these changes a picture of the function of different fi nancial institutions emerges which allows the concerns that have been expressed about recent developments in financial markets to be re evaluated the worrying implication is that systems for correcting substantial financial disruption are not yet in place

information use and acquisition in price setting oligopolies asymmetric price setting multi product suppliers have access to multiple sources of information about demand conditions where the publicity of each source corresponds to the cross industry correlation of signals received from it a signal s influence on suppliers prices is increasing in its publicity as well as in its precision the emphasis on relatively public information is stronger for smaller suppliers who control narrower product portfolios when information is endogenously acquired suppliers listen to only a subset of information sources this subset is smaller when products are less differentiated and when the industry is less concentrated smaller suppliers focus attention on fewer information sources the inefficiencies arising from information acquisition and use are identified the associated externalities depend upon the extent of product differentiation the concentration of the industry and the degree of decreasing returns to scale

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

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

british infrastructure policy and the gradual return of the state the state of british infrastructure is the source of almost continuous study and criticism there is now a host of new demands in water energy transport and communications which require a step change in investment the coalition government has made a series of reforms to planning finance and the setting of priorities which have been drawn together in national infrastructure plan statements a number of high profile and large scale projects have been advanced this paper sets out the evolution of these policy interventions and explains why government involvement is critical to their success it documents the gradual return of the state as part of a process of underpinning the investment costs in the provision of credible contracts and in closing the gap between public and private costs of capital it suggests that rather than pursue infrastructure policy as a set of priority projects greater use of regulated asset bases and attention to the time inconsistency problem would better achieve the overarching objectives

voting behavior and information aggregation in elections with private information we analyze two candidate elections in which voters are uncertain about the realization of a state variable that affects the utility of all voters each voter has noisy private information about the state variable we show that the fraction of voters whose vote depends on their private information goes to zero as the size of the electorate goes to infinity nevertheless elections fully aggregate information in the sense that the chosen candidate would not change if all private information were common knowledge equilibrium voting behavior is to a large extent determined by the electoral rule i e if a candidate is required to get at least x percent of the vote in order to win the election then in equilibrium this candidate gets very close to x percent of the vote with probability close to one finally if the distribution from which preferences are drawn is uncertain then elections will generally not satisfy full information equivalence and the fraction of voters who take informative action does not converge to zero

on the intergenerational allocation of natural resources it is known hartwick and others that under standard assumptions a society that invests in reproducible capital the competitive rents on its current extraction of exhaustible resources will enjoy a consumption stream constant in time it is shown here that this result can be interpreted as saying that an appropriately defined stock of capital including the initial endowment of resources is being maintained intact and that consumption can be interpreted as the interest on that patrimony this seems like a useful rule of thumb for policy

the propensity to patent abstract this paper analyzes the relationship between 1974 rd among the exceptions the tendency was toward diminishing returns variables measuring overseas sales federal r d support diversification scope of invention use and invention type had only modest explanatory power there was no significant evidence of disproportionate patent accumulation in the more highly concentrated industries

toward a strategic foundation for rational expectations equilibrium a step toward a strategic foundation for rational expectations equilibrium is taken by considering a double auction with n buyers and m sellers with interdependent values and affiliated private information if there are sufficiently many buyers and sellers and their bids are restricted to a sufficiently fine discrete set of prices then generically there is an equilibrium in nondecreasing bidding functions that is arbitrarily close to the unique fully revealing rational expectations equilibrium of the limit market with unrestricted bids and a continuum of agents in particular the large double auction equilibrium is almost efficient and almost fully aggregates the agents information

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 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

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

rational expectations information acquisition and competitive bidding most rational expectations market equilibrium models are not models of price formation and naive mechanisms leading to such equilibria can be severely manipulable in this paper a bidding model is developed which has the market like features that bidders act as price takers and that prices convey information higher equilibrium prices convey more favorable information about the quality of the objects being sold than do lower prices bidders can benefit from trading only if they have a transactions motive or if they have access to inside information apart from exceptional cases prices are not fully revealing a two stage model is developed in which bidders may acquire information at a cost before bidding and for which the equilibrium price is fully revealing resolving a well known paradox

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

endogenous public information and welfare in market games this paper performs a welfare analysis of markets with private information in which agents can condition on noisy prices in the rational expectations tradition pricecontingent strategies introduce two externalities in the use of private information a payoff pecuniary externality related to aggregate volatility and a learning externality the impact of the first depends on whether competition is of the strategic substitutes or complements variety and the second induces agents to put too little weight on private information we find that with strategic substitutes and when the learning externality is not very strong agents put too much weight on private information and prices are too informative this will happen in the normal case where the allocational role of price prevails over its informational role under strategic complementarity there is always under reliance on private information the welfare loss at the market solution may be increasing in the precision of private information the analysis provides insights into optimal business cycle policy and a rationale for a tobin like tax for speculators in financial markets

taking natural capital seriously the paper sets out a pragmatic case for preserving the aggregate level of natural capital in the face of the declines in biodiversity and the rising population and major increases in consumption that economic growth will bring in this century the accounting framework to achieving this objective is considered focused on the role of asset registers particular attention is paid to renewable assets at risk of falling below critical thresholds these assets are key components of the balance sheet capital maintenance expenditures are required to maintain the value of assets intact since renewable natural assets should not be depreciated but rather treated as assets in perpetuity within the aggregate substitutions with other forms of capital are permitted but only if there is compensation for any detriment to natural capital offsetting is one mechanism for achieving this compensation the case for enhancing the aggregate is considered and the paper shows how a broader national plan over a generation could contribute to the policy objective of leaving the next generation with a richer endowment of natural capital the policy instruments for embedding natural capital into public policy are reviewed

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

duopoly information equilibrium cournot and bertrand abstract in a duopoly model where firms have private information about an uncertain linear demand it is shown that if the goods are substitutes not to share information is a dominant strategy for each firm in bertrand cournot competition if the goods are complements the result is reversed furthermore the following welfare results are obtained 1 i with substitutes in cournot competition the market outcome is never optimal with respect to information sharing but it may be optimal in bertrand competition if the products are good substitutes with complements the market outcome is always optimal 2 ii bertrand competition is more efficient than cournot competition 3 iii the private value of information to the firms is always positive but the social value of information is positive in cournot and negative in bertrand competition

uncertainty resolution private information aggregation and the cournot competitive limit a cournot model of oligopoly in which otherwise identical firms have private differential information about the common cost of production and a shared but unknown demand curve is examined a bayesian equilibrium of the corresponding game of incomplete information is solved for explicitly and analysed in the symmetric equilibrium different firms produce at different output levels because they have different information because the information individual firms have is random total output and hence market price is also random for any finite number of firms the main result of the paper relates to the asymptotic properties of the equilibrium when the number of firms becomes large under fairly general conditions on the joint distribution of demand and individual firms information about demand the random equilibrium price converges almost surely to a constant in the limit more importantly this price equals the perfectly competitive price in other words in large markets even if no firm knows the true market demand curve and firms are not price takers and do not use price as a signal to improve their information the competitive price will prevail with certainty in the limit aggregate outcomes are as if all firms shared their private information with each other

cartel enforcement with uncertainty about costs what cartel agreements are possible when firms have private information about production costs in order for a cartel agreement to work it must take into account the incentives for firms to misrepresent their cost information and it must provide sufficient reward so that no firm wishes to defect for private cost uncertainty we characterize the set of cartel agreements with side payments that can be supported as bayesian nash equilibria we show that if defection results in either cournot or bertrand competition the incentive problems in large cartels are severe enough to prevent the cartel from achieving the monopoly outcome in contrast with common cost uncertainty the incentive problems become less severe in large cartels allowing perfect collusion

cournot competition and the social value of information in a differentiated product cournot model each supplier receives informative signals about demand the cross industry correlations of the signals differ more public signals have higher correlation coefficients in equilibrium information is used inefficiently from the industry s perspective information is over used and too much emphasis is placed on relatively public signals from the consumer s perspective information is under used and too much emphasis is placed on relatively private signals welfare is enhanced by increasing the use of information as desired by consumers but re balancing that use away from public signals as desired by the industry if information is costly and endogenously acquired then suppliers acquire too much new information but they use it too little

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

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

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

an empirical analysis of the revival of fiscal activism in the 2000s an empirical review of the three fiscal stimulus packages of the 2000s shows that they had little if any direct impact on consumption or government purchases households largely saved the transfers and tax rebates the federal government only increased purchases by a small amount state and local governments saved their stimulus grants and shifted spending away from purchases to transfers counterfactual simulations show that the stimulus induced decrease in state and local government purchases was larger than the increase in federal purchases simulations also show that a larger stimulus package with the same design as the 2009 stimulus would not have increased government purchases or consumption by a larger amount these results raise doubts about the efficacy of such packages adding weight to similar assessments reached more than thirty years ago jel e21 e23 e32 e62 h50

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

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
