where do markets come from production markets have two sides producers are a fully connected clique transacting with buyers as a separate but aggregated clique each producer is a distinctive firm with a distinctive product each side continually monitors reactions of the other through the medium of a joint social construction the schedule of terms of trade each producer is guided in choice of volume by the tangible outcomes of other producers not by speculation on hypothetical reactions of buyers to its actions each producer acts purely on self interest based on observed actions of all others summarized through a feedback process the summary is the terms of trade schedule which reduces to constant price only in limiting cases the market emerges as a structure of roles with a differentiated niche for each firm explicit formulae both for firms and for market aggregates are obtained by comparative statics methods for one family of assumptions about cost structures and about buyers evaluations of differentiated products not just any set of firms can sustain terms of trade with any set of buyers there prove to be three main kinds of markets and three sorts of market failure within a parameter space that is specified in detail one sort of market paradox has a madison avenue flavor another is more conventional grind and a third crowded is a new form not included in any existing theory of markets current american industrial markets are drawn on for 20 illustrations of which three are presented in some detail inequality in firms market shares measured by gini coefficients is discussed

kinship in the shadow of the corporation the interbuilder network in clyde river shipbuilding 1711 1990 the authors identify a system of intercompetitor affiliation that helped clyde river shipbuilding companies to thrive but was ultimately undermined by the rise of corporate capitalism they find that connections between companies through their leaders family ties or friendships were common and beneficial as every such tie maintained by a company reduced its annual risk of failure by 10 percent this average effect however masks an important contingency the direct benefits of interbuilder ties accrued only to family firms which enjoyed a reduced risk of failure of 34 percent with each tie and not at all to corporations the authors maintain that the shift to the corporate form inhibited the operation of the interbuilder network by reducing the autonomy of leaders to work through personal relations with their competitors the results encourage heightened attention both to the idea that horizontal ties within an industry may be a key determinant of organizational success and to the idea that some m

who appropriates centrality rents the role of institutions in regulating social networks in the global islamic finance industry this study explains and tests the effects of country level institutions on the distribution of centrality rents between two sets of actors in an interorganizational network building on the literature on corporate elites we propose that a cohesive elite following organizational logics other than profit maximization diverts centrality rents and induces costs on firms and that macro institutions act as external governance mechanisms to shape this relationship we develop our theory in the emerging islamic finance industry where shariah scholars connect firms and constitute a religious corporate elite while central scholars in this network create legitimacy for firms they also shirk and cause information leakage suggesting a negative centrality performance relationship for the firms country level institutions such as government regulation and democracy we argue ameliorate these effects by influencing this religious elite s institutional logic and restraining their actions while institutions developed from within the industry strengthen the power of the elite testing our theory in a network of 367 scholars and 396 institutions over 31 countries using multi level methods we indeed find a negative centrality performance relationship that is ameliorated by stronger government regulation but exacerbated by better developed industry specific institutions as well as a negative relationship between democratic and regulatory institutions and centrality

an appraisal of alternative blueprints for international policy coordination this paper examines two schemes for the international coordination of macroeconomic policy using a world econometric model the national institute global econometric model the first is the extended target zone scheme proposed by j williamson and m miller 1987 which involves targeting fundamental equilibrium exchange rates using monetary policy and using fiscal policy to control domestic demand the second uses fiscal policy to target the current account and monetary policy to stabilize domestic demand both schemes are parameterized using optimal control techniques on the national institute global econometric model and the welfare gains in using these schemes compared to historical experience from 1974 to 1986 are assessed

education and invention abstract modern growth theory puts invention on the center stage inventions are created by individuals raising the question of whether we can increase the number of inventors to answer this question we study the causal effect of msc engineering education on invention using data on u s patents finnish inventors and the distance to the nearest technical university as an instrument we find a positive effect of engineering education on the propensity to patent and a negative ols bias our counterfactual calculation suggests that establishing three new technical universities resulted in a 20 increase in the number of uspto patents by finnish inventors

patent trolls on markets for technology an empirical analysis of npes patent acquisitions abstract patent trolls or npes appropriate profits from innovation solely by enforcing patents against infringers they are often characterized as relying on low quality patents an assessment that if correct would imply that eradicating such patents would effectively terminate the npe business in this paper we shed light on this issue by empirically analyzing npes patent acquisitions we draw on a unique dataset of 392 u s patents acquired by known npes between 1997 and 2006 which we compare to three control groups of 784 u s patents each acquired by practicing firms we find that the probability that a traded patent is acquired by an npe rather than a practicing entity increases in the scope of the patent in the patent density of its technology field and contrary to common belief in the patent s technological quality our findings thus support recent theoretical propositions about the npe business model showing that npes procure patents that are more likely to be infringed harder to substitute for and robust to legal challenges the fact that npe acquired patents are of significantly higher quality than those in the control group implies that elevating minimum patent quality will not put an end to the npe business and suggests that this business is sustainable in the long run we furthermore discuss the fact that npes are peculiar players on markets for technology insofar as they are solely interested in the exclusion right not in the underlying knowledge we posit that transactions involving npes may only be the tip of the iceberg of patent only transactions a conjecture with strong implications for the efficiency and the study of markets for technologies managerial and policy implications are discussed

international search behavior of business group affiliated firms scope of institutional changes and intragroup heterogeneity this paper investigates whether and when affiliation to business groups enables or constrains firms international search behavior during institutional transitions we theorize that given the unique structure and complex form of business group organizations the search behavior of affiliated firms is influenced by the degree of misalignment in outlook at the group and affiliate levels of management we identify the scope of institutional changes business group attributes and affiliate characteristics as sources of such misalignment the results from panel data on 298 firms from the indian pharmaceutical industry for the 1992 2007 period show that the constraining effects of business group affiliation are observed only when institutional changes are specific to the affiliates industry and not when broad institutional changes affect the business group as a whole moreover we observe heterogeneity in the search behavior of group affiliated firms first the degree of misalignment is greater in the case of affiliates belonging to older business groups and those that are more distant in terms of age and industry since the group s founding second by contrast and suggesting an alignment in outlook we find that affiliated firms that occupy a prominent position within a group or industry are able to bargain for and receive attention and support from the business group to undertake international search our findings have implications for research on the role of business groups in a changing institutional context and for the strategic adaptation of firms embedded in complex organizational and institutional settings

technology gap global value chain and carbon intensity evidence from global manufacturing industries abstract the technological progress of a country may mean that its technology gap compared to the frontier has changed which will induce a change in its positioning in the global value chain and affect its carbon intensity using paten data input output database and the global value chain index we employ systematic generalized method of moments quantile regression with panel data and multilevel mediation analysis to measure empirically the impact of the technology gap on carbon intensity and positioning on the global value chain the empirical analysis shows that narrowing the technology gap will reduce significantly a country s carbon intensity further the effect of the technology gap on carbon intensity is more pronounced on industries with higher carbon intensity the mechanism test using the mediation effect model proves that the impact of the technology gap on carbon intensity is achieved by changing in the position of global value chain the findings suggest that a country s carbon intensity performance is not only affected by its own technological progress but also by global frontiers therefore a country should not only pay attention to its own technological progress but also to the development of global frontier technologies and speed of technological progress

fiscal policy banks and the financial crisis this paper studies the effectiveness of euro area ea fiscal policy during the recent financial crisis using an estimated new keynesian model with a bank a key dimension of policy in the crisis was massive government support for banks that dimension has so far received little attention in the macroeconomics literature we use the estimated model to analyze the effects of bank asset losses of government support for banks and other fiscal stimulus measures in the ea our results suggest that support for banks had a stabilizing effect on ea output consumption and investment increased government purchases helped to stabilize output but crowded out consumption higher transfers to households had a positive impact on private consumption but a negligible effect on output and investment banking shocks and increased government spending explain half of the rise in the public debt gdp ratio since the onset of the crisis

international spillovers of large scale asset purchases this paper evaluates the international spillover eects of large scale asset purchases lsaps using a two country dynamic stochastic general equilibrium model with nominal and real rigidities and portfolio balance eects portfolio balance eects arise from imperfect substitution between short and long term bond portfolios in each country as well as between domestic and foreign bonds within these portfolios we show that lsaps lower both domestic and foreign long term yields and stimulate economic activity in both countries international spillover eects

euro area and us external adjustment the role of commodity prices and emerging market shocks abstract the trade balances of the euro area ea and of the us have improved markedly after the global financial crisis this paper quantifies the drivers of ea and us economic fluctuations and external adjustment using an estimated 1999 2017 three region us ea rest of world dsge model with trade in manufactured goods and in commodities in the model commodity prices reflect global demand and supply conditions the paper highlights the key contribution of the post crisis collapse in commodity prices for the ea and us trade balance reversal aggregate demand shocks originating in emerging markets too had a significant impact on ea and us trade balances the broader lesson of this paper is that emerging markets and commodity shocks are major drivers of advanced countries trade balances and terms of trade

innovation cycles and learning at the patent office does the early patent get the delay we study the relationship between the length of patent review and the importance of inventions we build a simple model of the u s patent review process among the model predictions are that controlling for a patent s position in a new technology cycle more important innovations would be approved more quickly also the approval delay is likely to decrease as an industry moves from the early stages of an innovation cycle to later stages these predictions are in line with the evidence we obtain from a data set on u s patents granted in the field of genetically modified crops from 1983 to 1999 we also show that failing to account for the innovation lifecycle as previous studies have done is likely to bias upwards the estimates of the relationship between delay and importance 2010 the authors journal compilation 2010 blackwell publishing ltd and the editorial board of the journal of industrial economics

publicly funded r d programs and survival of patents i apply a survival model to a detailed data set of swedish patents to estimate how different financing factors affect the likelihood of patent renewal since the owners know more about the patents than potential external financiers there is a problem of asymmetric information to overcome this sweden has for a long time relied on government support rather than private venture capital pvc in the empirical analysis two kinds of government loans are unbundled the empirical results show that patents which have received soft government loans in the r d phase have a higher probability of expiring than patents without such financing but patents that have received more market oriented government loans during the commercialization phase are renewed for as long as other commercialized patents this finding suggests that rather than bad choices of projects it is the nature of the contract terms that explains the low renewal of some patents with government financing

r d co practice and reverse knowledge integration in multinational firms this paper contributes to the developing literature on the management of distributed innovation in multinational firms we focus on a specific organizational mechanism r d co practice which we believe is an important facilitator of knowledge integration in multinationals with global innovation strategies in our formulation r d co practice joint technical activities between units increases levels of absorptive capacity and social capital among participating units thus increasing the likelihood that they will share knowledge at future time periods we find strong support for this hypothesis through an empirical analysis of reverse subsidiary to headquarters knowledge integration in two sectors automotive and pharmaceuticals over a 21 year period

evaluating an estimated new keynesian small open economy model abstract this paper estimates and tests a new keynesian small open economy model in the tradition of christiano et al 2005 nominal rigidities and the dynamic effects of a shock to monetary policy journal of political economy 113 1 1 45 and smets and wouters 2003 an estimated stochastic dynamic general equilibrium model of the euro area journal of the european economic association 1 5 1123 1175 using bayesian estimation techniques on swedish data to account for the switch to an inflation targeting regime in 1993 we allow for a discrete break in the central bank s instrument rule a key equation in the model the uncovered interest rate parity uip condition is well known to be rejected empirically therefore we explore the consequences of modifying the uip condition to allow for a negative correlation between the risk premium and the expected change in the nominal exchange rate the results show that the modification increases the persistence in the real exchange rate and that this model has an empirical advantage compared with the standard uip specification

on the structural interpretation of the smets wouters risk premium shock this article shows that the risk premium shock in smets and wouters 2007 can be interpreted as a structural shock to the demand for safe and liquid assets such as short term u s treasury securities several implications of this interpretation are discussed

the welfare analysis of product innovations with an application to computed tomography scanners the main goal of this paper is to put forward a methodology for the measurement of product innovations using a value metric that is equating the magnitude of innovations with the welfare gains they generate this research design is applied to the case of computed tomography scanners a revolutionary innovation in medical technology the econometric procedure centers on the estimation of a discrete choice model the nested multinominal logit which yields the parameters of a utility function defined over the changing quality dimensions of the innovative product the estimated flow of social gains from innovation is used to compute a social rate of return to r d to explore the interrelation between innovation and diffusion and to trace the time profile of benefits and costs the latter suggesting the possible occurrence of technological cycles

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

real wage rigidities and the new keynesian model most central banks perceive a trade off between stabilizing inflation and stabilizing the gap between output and desired output however the standard new keynesian framework implies no such trade off in that framework stabilizing inflation is equivalent to stabilizing the welfare relevant output gap in this paper we argue that this property of the new keynesian framework which we call the divine coincidence is due to a special feature of the model the absence of nontrivial real imperfections we focus on one such real imperfection namely real wage rigidities when the baseline new keynesian model is extended to allow for real wage rigidities the divine coincidence disappears and central banks indeed face a trade off between stabilizing inflation and stabilizing the welfare relevant output gap we show that not only does the extended model have more realistic normative implications but it also has appealing positive properties in particular it provides a natural interpretation for the dynamic inflation unemployment relation found in the data

occbin a toolkit for solving dynamic models with occasionally binding constraints easily abstract the toolkit adapts a first order perturbation approach and applies it in a piecewise fashion to solve dynamic models with occasionally binding constraints our examples include a real business cycle model with a constraint on the level of investment and a new keynesian model subject to the zero lower bound on nominal interest rates compared with a high quality numerical solution the piecewise linear perturbation method can adequately capture key properties of the models we consider a key advantage of the piecewise linear perturbation method is its applicability to models with a large number of state variables

what determines patent value insights from the semiconductor industry abstract this paper contributes to an understanding which impacts certain patent characteristics have on the value of patent rights in an exploratory study 127 individual patents from a semiconductor company were evaluated comprehensively by technical and marketing representatives the analysis of this rare data shows that for patents used as bargaining chips novelty and inventive activity are most important difficulty of inventing around and disclosure turn out to be of limited importance due to a selection bias the influence of patent age on its value cannot be determined the results hint at a differentiated theoretical plausibility of value indicators

automatic stabilizers and economic crisis us vs europe this paper analyzes the effectiveness of the tax and transfer systems in the eu and the us to provide income insurance through automatic stabilization in the recent economic crisis we find that automatic stabilizers absorb 38 of a proportional income shock in the eu compared to 32 in the us in the case of an unemployment shock 47 of the shock is absorbed in the eu compared to 34 in the us this cushioning of disposable income leads to a demand stabilization of up to 30 in the eu and up to 20 in the us there is large heterogeneity within the eu automatic stabilizers in eastern and southern europe are much lower than in central and northern european countries we also investigate whether countries with weak automatic stabilizers have enacted larger fiscal stimulus programs

the embeddedness of networks institutions structural holes and innovativeness in the fuel cell industry plentiful research suggests that embeddedness in alliance networks influences firms innovativeness this research however has mostly overlooked the fact that interorganizational ties are themselves embedded within larger institutional contexts that can shape the effects of networks on organizational outcomes we address this gap in the literature by arguing that national institutions affect the extent to which specific network positions such as brokerage influence innovation we explore this idea in the context of corporatism which fosters an institutional logic of collaboration that influences the broker s ability to manage its partnerships and recombine the knowledge residing in its network as well as the extent of knowledge flows among network participants we argue that differences in institutional logics lead brokerage positions to exert different effects on firm innovativeness we propose that the firm spanning structural holes obtains the greatest innovation benefits when the firm the broker or its alliance partners are based in highly corporatist countries or under certain combinations of broker and partner corporatism we find support for these ideas through a longitudinal study of cross border fuel cell technology alliance networks involving 109 firms from nine countries between 1981 and 2001

cooperation and political economic performance in affluent democratic capitalism research on comparative political economic performance has traditionally followed two separate tracks one concerned with collective economic gain growth and efficiency and the other focused on distribution and redistribution cooperative institutions offer a key to understanding cross national variation among the affluent capitalist democracies in both facets of political economic performance these institutions cluster along two dimensions neocorporatism and firm level cooperation pooled time series analysis for 18 nations over 1960 89 suggests that 1 neocorporatism is a major source of distributive redistributive policies and outcomes and of several sources of collective gain 2 firm level cooperation is a key contributor to economic growth

a dynamic analysis of university agricultural biotechnology patent production this article examines the factors that account for agricultural biotechnology patenting success among universities using a dynamic count data model it builds a theoretical and econometric model to capture the inherently dynamic and nonlinear process of technological innovation wherein a feedback mechanism from previous success partially determines current patent counts the econometric estimates reveal the importance to agricultural biotechnology patent production of land grant infrastructure quality faculty patent oriented technology transfer offices as well as dynamic feedback effects the advent of exclusive property rights for university research specifically the bayh dole act has created the potential for major changes in the missions of u s universities especially among land grant universities lgus as well as in the overall system of technology creation and distribution in agriculture at the same time new genetic and cloning technologies along with the recently created ability to patent plants and living organisms are profoundly changing the range of agricultural technologies that are likely to be available in the united states and internationally indeed as zilberman yarkin and heiman argue these new agricultural biotechnologies ag biotech and their associated intellectual property rights appear to be creating a new paradigm a veritable revolution in the organization and interaction of university research and the agricultural sector under this new paradigm universities emphasize patenting innovations and then granting at times

choosing organizational modes of strategic technology partnering international and sectoral differences this paper focuses on international strategic technology partnerships and the choice that companies have in terms of the organizational mode either through complex inter organizational modes involving equity sharing or contractual non equity alliances the empirical results show that the choice of particular mode of cooperation varies with the technological characteristics of sectors of industry joint ventures are disproportionately represented in relatively mature industries contractual alliances dominate strategic technology partnering in so called high tech industries

patents learning by doing and market structure in the chemical processing industries for a sample of 24 chemical products count data models are used to evaluate firms propensity to patent and the link between patented process innovations and output prices the results show that process patenting was largely an outgrowth of learning by doing propensity to patent increased with firm size but decreased with market concentration reductions in output prices were strongly linked to learning by doing and more weakly to the rate of patenting producer firms appear to have been more successful than non producers in appropriating the value of patented process innovations

characteristics of patent litigation a window on competition we examine the patenting behavior of firms in an industry characterized by rapid technological change and cumulative innovation recent survey evidence suggests that semiconductor firms do not rely heavily on patents to appropriate returns to r d yet the propensity of semiconductor firms to patent has risen dramatically since the mid 1980s we explore this apparent paradox by conducting interviews with industry representatives and analyzing the patenting behavior of 95 u s semiconductor firms during 1979 1995 the results suggest that the 1980s strengthening of u s patent rights spawned patent portfolio races among capital intensive firms but it also facilitated entry by specialized design firms copyright 2001 by the rand corporation

determinants of cross national knowledge transfer and its effect on firm innovation this study examines the determinants of international knowledge flow from a resource based perspective it evaluates the impact of cross national knowledge transfer on firm innovative performance based on 56 027 us patents owned by 53 selected firms in the us based pharmaceutical industry the results suggest that innovative performance is a curvilinear function of the international knowledge content used by a firm to innovate as hypothesized it was found that at 1 low and moderate levels of international knowledge content a firm s strategy to transfer international knowledge improves its innovative performance and at 2 higher levels of international knowledge content there are diminishing marginal returns to transferring knowledge from overseas

networks diversity and productivity the social capital of corporate r d teams we argue that the debate regarding the performance implications of demographic diversity can be usefully reframed in terms of the network variables that reflect distinct forms of social capital scholars who are pessimistic about the performance of diverse teams base their view on the hypothesis that decreased network density the average strength of the relationship among team members lowers a team s capacity for coordination the optimistic view is founded on the hypothesis that teams that are characterized by high network heterogeneity whereby relationships on the team cut across salient demographic boundaries enjoy an enhanced learning capability we test each of these hypotheses directly and thereby avoid the problematic assumption that they contradict one another our analysis of data on the social networks organizational tenure and productivity of 224 corporate r d teams indicates that both network variables help account for team productivity these findings support a recasting of the diversity performance debate in terms of the network processes that are more proximate to outcomes of interest

the dynamics of learning alliances competition cooperation and relative scope we show how the tension between cooperation and competition affects the dynamics of learning alliances private benefits and common benefits differ in the incentives that they create for investment in learning the competitive aspects of alliances are most severe when a firm s ratio of private to common benefits is high we introduce a measure relative scope of a firm in an alliance to show that the opportunity set of each firm outside an alliance crucially impacts its behavior within the alliance finally we suggest why firms might deviate from the theoretically optimal behavior patterns 1998 john wiley sons ltd

the dynamics of the transfer and renewal of patents this article explores new data on the transfer and renewal of u s patents and interprets this new evidence using a model of patent transfers and renewal we find that the proportion of transferred patents is large and differs across technology fields and especially type of patentees we also find that the probability of a patent being traded depends on a number of factors the age of the patent the number of citations received by a given age the patent generality and whether the patent has been previously traded or not these findings are consistent with the predictions of a model of patent transfers and renewals

factor hoarding and the propagation of business cycles shocks this paper analyzes the role of variable capital utilization rates in propagating shocks over the business cycle to this end we formulate and estimate an equilibrium business cycle model in which cyclical capital utilization rates are viewed as a form of factor hoarding we find that variable capital utilization rates substantially magnify and propagate the impact of shocks to agents environments the strength of these propagation effects is evident in the dynamic response functions of various economy wide aggregates to shocks in agents environments in the statistics that we construct to summarize the strength of the propagation mechanisms in the model and in the volatility of exogenous technology shocks needed to explain the observed variability in aggregate u s output other authors have argued that standard real business cycle rbc models fail to account for certain features of the data because they do not embody quantitatively important propagation mechanisms these features include the observed positive serial correlation in the growth rate of output the shape of the spectrum of the growth rate of real output and the correlation between the forecastable component of real output and various other economic aggregates allowing for variable capital utilization rates substantially improves the ability of the model to account for these features of the data

international patent protection 1960 2005 abstract this note provides an update to the index of patent protection published in this journal in 1997 the original paper presented the index for 1960 1990 for 110 countries the index has now been updated to 2005 and extended to 122 countries the adoption of stronger patent laws and the composition of patent rights vary across countries by level of economic development

co ownership of intellectual property exploring the value appropriation and value creation implications of co patenting with different partners combining both interview data and empirical analyses at the patent and firm levels we explore the value appropriation and value creation implications of r d collaboration resulting in the co ownership of intellectual property i e co patents we make an explicit distinction between three different types of co patenting partners intra industry partners inter industry partners and universities our findings indicate that the value appropriation challenges of ip sharing are clearly evident with intra industry co patenting where partners are more likely to encounter overlapping exploitation domains co patenting with universities is associated with higher market value since appropriation challenges are unlikely to play a role and collaboration may signal novel technological opportunities although we find some evidence that co patenting corresponds to higher patent value patents co owned with firms are significantly less likely to receive self citations indicating constraints on the future exploitation and development of co owned technologies

the effect of national culture on the choice of entry mode characteristics of national cultures have frequently been claimed to influence the selection of entry modes this article investigates this claim by developing a theoretical argument for why culture should influence the choice of entry two hypotheses are derived which relate culture to entry mode choice one focusing on the cultural distance between countries the other on attitudes towards uncertainty avoidance using a multinomial logit model and controlling for other effects the hypotheses are tested by analysing data on 228 entries into the united states market by acquisition wholly owned greenfield and joint venture empirical support for the effect of national culture on entry choice is found

financial spillover and global risk in a multi region model of the world economy abstract this paper estimates a three region dsge model ea us row with international financial linkages in the form of cross border equity holding and allowing for region specific as well as global financial shocks which match empirical measures of financial tightness and global stock market valuation spillover from financial shocks increases with international financial integration and is practically zero under full home bias in normal times the global risk captures international synchronisation of financial cycles spillover of financial shocks is amplified at the zero lower bound at which investment risk takes on the characteristics of a general uncertainty shock the model results suggest that integrated financial markets should provide a powerful motivation for international policy coordination to prevent financial turmoil

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

target zones and international policy coordination the contrast between the necessary and sufficient conditions for success abstract this paper distinguishes between the necessary and sufficient conditions for adopting exchange rate target zones for improving macroeconomic performance the necessary conditions are easily satisfied but it is much more difficult to design a targetting system which satisfies the sufficient conditions when the exchange rate is an intermediate target on that criterion the gains may be smaller than previously estimated however target zones have important practical advantage they are effective in promoting stability and as a simple but uncontroversial way of securing the coordination necessary to prevent policy makers adopting inefficient or competitive policies

derivative ideas and the value of intangible assets we build a general equilibrium model where growth is driven by two invention types fundamental ideas that cause creative destruction and derivative ideas that enhance the value of existing inventions the model provides a new mapping from microeconomic patent data to aggregate total factor productivity growth and the aggregate value of privately owned knowledge we show how to measure the frequency of derivative ideas and the rate of creative destruction we estimate that derivative ideas account for 70 80 of all patents and their presence more than doubles the value of knowledge capital relative to what the measured innovation rate might otherwise imply

the macroeconomic effects of quantitative easing in the euro area evidence from an estimated dsge model this paper analyses the macroeconomic effects of the ecb s quantitative easing programme using an open economy dsge model estimated with bayesian techniques using data on government debt stocks and yields across maturities we identify the parameter governing portfolio adjustment in the private sector shock decompositions suggest a positive contribution of ecb qe to ea year on year output growth and inflation of up to 0 4 and 0 5 pp in the standard linearised version of the model allowing for an occasionally binding zero bound constraint by using piecewise linear solution techniques raises the positive impact up to 1 0 and 0 7 pp respectively

consumption real exchange rates and the structure of international asset markets abstract international real business cycle irbc models that assume complete asset markets yield strong restrictions for consumption and bilateral real exchange rate series empirical tests with data for the us japan france uk italy canada and sweden suggest that neither the trend behavior nor high frequency movements of consumption and real exchange rates are well explained by irbc models with complete markets it appears however that high frequency fluctuations of consumption and real exchange rates are consistent with unrestricted international trade in risk free bonds

r d spillovers patents and the incentives to innovate in japan and the united states national surveys of r d labs across the manufacturing sectors in the us and japan show that intraindustry r d knowledge flows and spillovers are greater in japan than in the us and the appropriability of rents due to innovation less patents in particular are observed to play a more central role in diffusing information across rivals in japan and appear to be a key reason for greater intraindustry r d spillovers there suggesting that patent policy can importantly affect information flows uses of patents differ between the two nations with strategic uses of patents particularly for negotiations being more common in japan

a penny for your quotes patent citations and the value of innovations the use ofpatents in economic research has been seriously hindered by the fact that patents vary enormously in their importance or value and hence simple patent counts cannot be informative about innovative output the purpose of this article is to put forward patent counts weighted by citations as indicators of the value of innovations thereby overcoming the limitations of simple counts the empirical analysis of a particular innovation computed tomography scanners indeed shows a close association between citation based patent indices and independent measures of the social value of innovations in that field moreover the weighting scheme appears to be nonlinear increasing in the number of citations implying that the informational content of citations rises at the margin as in previous studies simple patent counts are found to be highly correlated with contemporaneous rd however here the association is within afield over time rather than cross sectional

specification of policy rules and performance measures in multicountry simulation studies abstract much recent analysis of international monetary and fiscal policy issues has been conducted by stochastic simulations with multicountry econometric models in these studies it has become standard practice to consider alternative policy rules of a form that calls for departures of a policy instrument from some baseline reference path that are proportional to deviations of a specified target variable from its own baseline path the present paper argues that this standard rule form is seriously defective for such issues because th eimplied rules often fail to be operational and have associated performance measures that can be misleading in important cases jel c50 f30

comparing shocks and frictions in us and euro area business cycles a bayesian dsge approach this paper estimates a dsge model with many types of shocks and frictions for both the us and the euro area economy over a common sample period 1974 2002 the structural estimation methodology allows us to investigate whether differences in business cycle behaviour are due to differences in the type of shocks that affect the two economies differences in the propagation mechanism of those shocks or differences in the way the central bank responds to those economic developments our main conclusion is that each of these characteristics is remarkably similar across both currency areas copyright 2005 john wiley sons ltd

change in domestic network centrality uncertainty and the foreign divestment decisions of firms abstract we investigate the role of domestic interfirm networks for the foreign divestment decisions of firms we argue that firms foreign operations risk being divested when a firm becomes more central in its domestic network positive changes in firm centrality at home facilitate access to information about new business opportunities but they may also lead firms to consider reconfiguring their value chain activities and resources across locations the resulting opportunity costs of maintaining foreign operations could subsequently lead to their divestment moreover we argue that the positive association between an increase in firm centrality in the domestic network and foreign divestment is stronger under higher uncertainty as pursuing new business opportunities at home becomes more appealing we distinguish between firm specific uncertainty and domestic market uncertainty we test and get support for our hypotheses using foreign subsidiary data from u s firms in the ict industry

patents as options some estimates of the value of holding european patent stocks in many countries holders of patents must pay an annual renewal fee in order to keep their patents in force this paper uses data on the proportion of patents renewed and the renewal fees faced by post world war ii cohorts of patents in france the united kingdom and germany in conjunction with a model of patent holders renewal decisions to estimate the returns earned from holding patents in these countries since patents are often applied for at a nearly stage in the innovation process the model allows agents to be uncertain about the sequence of returns that will be earned if the patent is kept inforce formally then the paper presents and solves a discrete choice optimal stochastic control model derives the implications of the model on aggregate behaviour and then estimates the parameters of the model from aggregate data the estimates enable a detailed description of the evolution of the distribution of returns earned from holding patents over their life spans and calculations of both the annual returns earned from holding the patents still in force or the patent stocks in the alternative countries and the distribution of the discounted value of returns earned from holding the patents in a cohort this abstract was borrowed from another version of this item

cross country causes and consequences of the crisis an update abstract we update rose and spiegel forthcoming rose and spiegel 2010 and search for simple quantitative models of macroeconomic and financial indicators of the great recession of 2008 09 we use a cross country approach and examine a number of potential causes that have been found to be successful indicators of crisis intensity by other scholars we check a number of different indicators of crisis intensity and a variety of different country samples while countries with higher income and looser credit market regulation seemed to suffer worse crises we find few clear reliable indicators in the pre crisis data of the incidence of the great recession countries with current account surpluses seemed better insulated from slowdowns

the technological origins of radical inventions this paper aims to trace down the origins of radical inventions in spite of many theoretical discussions on the effect of radical inventions the specific nature of radical inventions has received much less attention in the theoretical and empirical literature we try to fill that void by an empirical investigation into the specific origins of radical inventions we explore this issue by a close examination of 157 individual patents which are selected from a pool of more than 300 000 patents in contrast to the conventional wisdom that radical inventions are based less on existing knowledge we find that they are to a higher degree based on existing knowledge than non radical inventions a further result that follows from our analysis is that radical inventions are induced by the recombination over more knowledge domains the combination of knowledge from domains that might usually not be connected seems to deliver more radical inventions

international knowledge brokerage and returnees entrepreneurial decisions based on the knowledge brokerage literature and the international entrepreneurship literature we investigate whether returnees international knowledge transfer affects their entrepreneurial decisions and the extent to which this relationship is contingent on perceived supportive policies for returnee entrepreneurship and returnees difficulties with cross cultural readjustment in their home countries analyzing first hand survey data we find a positive relationship between international knowledge transfer and returnees decisions to become entrepreneurs this positive relationship is strengthened by the perception of the home country s supportive policies for returnee entrepreneurship but is weakened by returnees perceived difficulties in readjusting to the local norms and culture in their home countries

the value of u s patents by owner and patent characteristics abstract this paper uses renewal data to estimate the value of u s patents controlling for patent and owner characteristics estimates of u s patent value are substantially larger than estimates for european patents however the ratio of u s patent value to r d for firms is only about 3 contrary to a common assertion patents issued to small patentees are much less valuable than those issued to large corporations litigated patents are more valuable as are highly cited patents however patent citations explain little variance in value suggesting limits to their use as a measure of patent quality

measuring patent s influence on technological evolution a study of knowledge spanning and subsequent inventive activity we introduce technological influence as a variable to measure an invention s direct and indirect impact on the evolution of technology this provides a novel means to study the short and long run effect of invention antecedents on technological evolution invention activity and economic growth a comparison between models of technological influence and direct technological impact is presented model estimations are based on data from semiconductor patents granted over a 5 year period results from quantile regression estimations show significant differences in the relationships between antecedents of technological influence and impact for example pioneering the spanning of knowledge boundaries has a positive relationship with the patent s influence while no relationship is found with direct citations these results have important implications for public policy and the management of technology they suggest the need for deeper understanding of the micro foundations of the technological evolution process and raise the question of whether inventors under current ip protection receive adequate economic incentives to promote actions driving economic growth

the international monetary system should it be reformed a casual glance through the proceedings of past annual meetings of the american economic association reveals that in almost every year during the past twenty years president elects of the aea have devoted at least one session to an examination of issues concerning the international monetary system prominent on the agenda has been the question of reform how should the international monetary system be reformed so as to function more effectively the premise underlying this question is that the international monetary system has failed and that it must be reformed by an institutional change in what follows i present some skeptical notes on both the verdict on the failure of the system and on some proposals for reform especially the target zones proposal to set the stage it is worth noting that one of the main sources of disenchantments with the present monetary system has been the unpredictability of exchange rates there has been nothing more confusing than reading through the ex post journalistic explanations offered for the day to day changes in the u s dollar for example over the past few years we were told that the dollar fell because the money supply grew faster than expected thereby generating inflationary expectations but on another occasion we were told that the dollar rose because the money supply grew faster than expectedthereby generating expectations that the fed is likely to tighten up and raise interest rates on another date we were told that the dollar fell since the budget deficit exceeded previous forecasts thereby generating inflationary expectations on the belief that the fed will have to monetize the deficit but on another occasion we were told that the dollar rose since the budget deficit exceeded previous forecasts thereby generating expectations that government borrowing needs will drive up interest rates since the fed is unlikely to give up its firm stance on yet another day we were told that the dollar fell since oil prices fell thereby hurting mexico and other debtriddenoil producing countries whose bad fortune may bring about the collapse of important u s banks but on another occasion we were told that the dollar rose since oil prices fell thereby helping the debt ridden oil consuming countries whose improved fortune will help the vulnerable position of important u s banks more recently the dollar changed again and this time the explanation was a bit more sophisticated the dollar changed because the extent of the revision of the estimated gnp growth rate was smaller than the expected revision of previous forecasts of these estimates one cannot but sympathize with the difficulties shared by newspaper reporters and financial analysts who feel obligated to come up with daily explanations for daily fluctuations of exchange rates and one can only imagine the deep frustration that yielded the recent headline in the international herald tribune according to which the dollar rose on no news the dismal performance of short term forecasting does not reflect a lack of effort rather it is an intrinsic characteristic of efficient asset markets difficulties in forecasting short term indices of stock markets like the dow jones index do not call however for a reform of the way stock markets operate for similar reasons one should not assess the performance of the international monetary system on the basis of short term forecastability of exchange rates this does international monetary fund washington d c 20431 university of chicago and national bureau of economic research the research reported here is part of the nber s research programs in international studies and economic fluctuations any opinions expressed are my own and not those of the national bureau of economic research 205

can patent family size and composition signal patent value abstractrecent research has proposed a method of patent valuation based on weighting patent family size by the market size of the countries in the family the premise is that inventors tend to seek

getting competition down to a science the effects of technological competition on firms scientific publications prior research about the interaction between private firms and the scientific community has largely viewed firms articles in scientific publications as a means to improve research and development productivity by encouraging their researchers to publish scientific papers firms can maintain linkages with the scientific community attract talent and access external knowledge on which they can build to create innovations this paper in contrast emphasizes the role of scientific publications in firms battles for market dominance and examines how competitive conditions shape firms propensities to publish scientific articles about their innovations focusing on the context of pharmaceutical drugs we develop propositions about how the competition that one drug faces from similar drugs and potential substitutes influences the innovating firm s inclination to publish articles in the top medical journals about that drug to facilitate its assessment by the u s food and drug administration and the medical community we also propose that scientific articles about competing drugs compel a firm to highlight its own drug in scientific papers to assert the drug s uniqueness and mitigate the threat of substitution whereas prior research has elucidated how science contributes to enhancing firms competence at creating innovations which is critical to their ability to compete in technology intensive environments this paper draws attention to how competition in turn permeates into the scientific arena creating inducements for firms to use scientific publications to position their innovations in the marketplace
