the organisation of innovation collaboration cooperation and multifunctional groups in uk and german manufacturing marked differences exist between the institutional and social context for innovation in the uk and germany the question addressed here is how these different contexts affect the objectives and organisation of innovation in uk and german manufacturing in particular the paper examines the extent to which uk and german plants engage in inter plant collaboration and cooperation and multifunctional working as part of their innovative activity and explores the reasons for differences in these patterns of involvement the investigation is based on a large scale comparative survey of manufacturing plants in the two countries in germany institutional and social norms are found to encourage collaborative inter plant innovation but aspects of the german skills training and industrial relations systems make the adoption of more flexible internal systems more difficult in the uk by contrast the more adversarial nature of inter firm relations makes it more difficult to establish external collaborations based on mutual trust but less restrictive labour market structures make it easier for uk plants to adopt multifunctional working this is linked to differences in attitudes to the property rights and transaction cost problems inherent in innovation

the changing technology of technological change general and abstract knowledge and the division of innovative labour abstract in the past most innovations have resulted from empiricist procedures the outcome of each trial yielding knowledge that could not be readily extended to other contexts while trial and error may remain the primary engine of innovation developments in many scientific disciplines along with progress in computational capabilities and instrumentation are encouraging a new approach to industrial research instead of relying purely on trial and error the attempt is also to understand the principles governing the behaviour of objects and structures the result is that relevant information whatever its source can now be cast in frameworks and categories that are more universal the greater universality makes it possible for the innovation process to be organised in new ways firms can specialise and focus upon producing new knowledge and the locus of innovation may be spread across both users and producers more generally the use of general and abstract knowledge in innovation opens up the possibility for a division of labour in inventive activity the division of innovative labour the implications for public policy especially that on intellectual property rights are discussed

partial retirement among women the labor supply response to critical aspects of the social security program depends on whether behavior is myopic conditioned by current benefits only or far sighted conditioned by the entire future benefit stream this behavior reflects

money new keynesian macroeconomics and the business cycle abstract we show in this paper that the typical modern business cycle cannot be reduced to the real business cycles archetype a monopolistic competition model with price adjustment costs affected by technological and monetary shocks better mimics the economic fluctuations in two countries with very different cyclical properties namely france and the united states in our model monetary shocks are necessary to reproduce the standard deviation of output the money output correlation the labour productivity worked hours relative standard deviation the labour productivity worked hours correlation and the mark up output correlation with two independent shocks one real more specifically defined than the solow residual and one nominal the model gives an answer to some empirical puzzles which were left unexplained by traditional rbc models

social security and the retirement decision the effect of social security and private pensions on individual retirement decisions is modeled relaxing in turn three commonly maintained assumptions perfect capital markets actuarial fairness and certain lifetimes which together imply that there is no effect in each case raising the contribution level can cause systematic changes of either sign in general in individual retirement decisions for social security the effects associated with forced saving and deviations from actuarial fairness probably tend to advance retirement but those effects that arise solely from the insurance aspect of social security and private pensions are ambiguous in sign owing to the presence of a substitution effect that tends to delay retirement because the insurance benefits can be fully realized only by working longer

a ricardian equivalence theorem on the taxation of pension funds abstract we compare the three main alternative ways of taxing pension funds of the defined contribution variety specifically the alternatives considered are equal yield taxes on contributions earnings and benefits analogous to the ricardian equivalence theorem the contributor s after tax benefit will be the same in each case

networks of innovators a synthesis of research issues abstract this paper will first summarise some key findings of empirical research in the 1960s on the role of external sources of scientific technical and market information in successful innovation by business firms this work demonstrated unambiguously the vital importance of external information networks and of collaboration with users during the development of new products and processes moreover the dilemmas of cooperative research in competitive industries were recognised and studied long ago 35 62 76 what then is new about the present wave of interest in networks of innovators are there new forms of organisation or new technologies or new policies which justify renewed research efforts since they go beyond those developments already analysed in earlier empirical and theoretical work section 2 reviews the evidence of new developments in the 1980s in industrial networks regional networks and government sponsored innovative activities it shows that there has indeed been a major upsurge of formal and semi formal flexible networks in the 1980s including some new types of network it also shows that some older forms of research cooperation have been modified and transformed the papers at montreal largely concentrated on the role of regional supplier networks which are a good example of such new wine in old bottles this paper attempts to locate the regional network discussion within a wider context of new developments in networking section 3 discusses the causes of these new developments and whether they are likely to remain a characteristic of national and international innovation systems for a long time to come or prove to be a temporary upsurge to be overtaken later by a wave of take overs and vertical integration finally section 4 sums up some of the other key issues which require further research and debate and the implications for social science theory

the joint choice of retirement age and postretirement hours of work in this paper we develop and estimate the first complete and internally consistent model of the effect of social security on the labor supply of the aged we develop a simple life cycle model that captures the effect of social security on the joint choice of the date of retirement and hours of work immediately after retirement we show that in the presence of social security the budget constraint relating these choices is highly complex and nonlinear and we develop a maximum likelihood procedure for the model that yields consistent parameter estimates our procedure avoids the selectivity biases present in prior studies that have ignored the nonlinearity of the constraint or have examined only self selected subsamples that exclude nonretirees our results show that social security has a significant though relatively small effect on the age of retirement and postretirement hours of work and that the effect of social security grows with advancing age

the effect of social security on retirement in the early 1970s we analyze detailed longitudinal data on a cohort of males aged 58 67 in 1969 1973 a period of substantial increases in real social security benefits we find the following 1 the accelerating decline in labor force participation of elderly men in 1969 1973 can be explained by the large increase in real social security benefits 2 there is evidence of a liquidity constraint effect for an important subgroup of the elderly 3 the magnitude of this induced retirement effect is large enough that ignoring it can lead to serious underestimation of the fiscal implications of changes in benefit provisions our results are interpreted in the historical context of a particular cohort undergoing major unanticipated transfers of wealth the steady state effects of social security on retirement may not be the same

the origins and dynamics of production networks in silicon valley abstract computer systems firms in silicon valley are responding to rising costs of product development shorter product cycles and rapid technological change by focusing and building partnerships with suppliers both within and outside of the region well known firms like hewlett packard and apple computers and lesser known ones like silicon graphics and pyramid technology are organized to combine the components and sub systems made by specialist suppliers into new computer systems as these firms collaborate to both define and manufacture new systems they are institutionalizing their capacity to learn from one another three cases a contract manufacturer a silicon foundry and the joint development of a microprocessor illustrate how inter firm networks help account for the sustained technological dynamism of the regional economy

the family as an incomplete annuities market families can self insure against uncertain dates of death through implicit or explicit agreements with respect to consumption and interfamily transfers interfamily transfers need have nothing to do with altruistic feelings they may simply reflect risk sharing behavior of completely selfish family members although family annuity markets are incomplete even small families can substitute by more than 70 percent for perfect market annuities given adverse selection and transaction costs family risk pooling may be preferred to public market annuities in the absence of public annuities these risk sharing arrangements provide powerful incentives for marriage and family formation

interpenetration of organization and market japan s firm and market in comparison with the u s abstract resource allocation mechanisms used in the market and within the firm are quite often a mixture of the pure market principle and the pure organization principle market principles penetrate into the firm s resource allocation and organization principles creep into the market allocation interpenetration occurs to remedy the failure of pure principles other in the market or in the organization after presenting this new perspective we analyze resource allocation mechanisms in japan and the u s one conclusion is that interpenetration patterns are rather different between the two countries due to institutional economic and societal differences we also analyze the ways in which these differences affect japanese and american corporate behavior in such areas as diversification strategy corporate financing and innovation and venture business activity

consumption during retirement the missing link in the life cycle this study presents the first evidence on the relation of consumption to lifetime wealth based on data from the 1973 and 1975 retirement history survey that have been linked to social security earnings records nearly 500 white married fully retired couples ages 62 69 form the basis of the analysis on average their consumption early in retirement exceeds by 14 percent the income that their financial pension and social security wealth can generate this implies that their saving both private and through social security is insufficient to sustain consumption throughout the rest of their lives additional evidence based on changes in spending between 1973 and 1975 shows that these households respond by reducing their real consumption at a rate sufficient to generate positive changes in net financial worth within a few years after retirement these two pieces of evidence can be rationalized by a rate of time preference much higher than the interest rate coupled with either a bequest motive or uncertainty about the length of life they also imply that even when combined with private pensions and savings social security in the united states today does not enable most recipients to maintain their living standard at the levels they enjoyed before they retired this abstract was borrowed from another version of this item

dynamic complementarities in innovation strategies using a panel of irish manufacturing plants over the period 1991 2008 we test for dynamic complementarities in the joint use of internal r d and external knowledge sources we find little evidence either from considering successive cross sectional waves of comparable surveys or in terms of the strategy switch choices of specific plants that there has been a systematic move towards the joint use of internal and external knowledge in innovation we then test formally for the presence of complementarities in the joint use of internal r d and external innovation linkages in static terms we find no evidence of complementarity but in dynamic terms find evidence that strategy switches by individual plants towards a more open strategy are accompanied by increased innovation outputs

the permanent income hypothesis estimation and testing by instrumental variables the permanent income hypothesis with rational expectation is restated estimated and tested by an instrumental variables technique on the postwar u s aggregate time series data the hypothesis is accepted on a consumption series which includes service flows from consumer durables if the consumption series is the one in the national income and product accounts the hypothesis is decisively rejected an explanation is suggested to reconcile the conflicting test results

comparing innovation systems a framework and application to china s transitional context abstract this paper proposes a generic framework for analyzing innovation systems anchored around five fundamental activities r d implementation end use education linkage and focused on the performance implications of a system s structure and dynamics rather than simply describing the role and performance of particular actors institutions and policies this approach focuses on system level characteristics including the distribution of these activities within the system the organizational boundaries around them coordination mechanisms evolutionary processes and the effectiveness of the system in introducing diffusing and exploiting technological innovations the framework is applied to a comparison of china s national innovation system under central planning and since reforms revealing the evolving structure and dynamics of this system and current inconsistencies and perverse incentives that policymakers must address to realize their development goals more generally it provides a basis for addressing the implicit assumptions of organizational types roles and convergence among innovation systems emerging in very different contexts whether national regional or industrial

business groups in a market economy abstract the purpose of this paper is to examine the nature and significance of the interfirm relationship called the business group first the nature of the japanese business group is discussed it is then pointed out that the business group is not a phenomenon unique to japan and an effort is made to explain the significance of the business group in the context of a market economy using the williamsonian approach to questions of internal organization and the market finally the relationship between the input output relationship of the firms and their group affiliation is tested

the acquisition and commercialization of invention in american manufacturing incidence and impact abstract recent accounts suggest the development and commercialization of invention has become more open greater division of labor between inventors and innovators can enhance social welfare through gains from trade and economies of specialization moreover this extensive reliance upon outside sources for invention also suggests that understanding the factors that condition the extramural supply of inventions to innovators is crucial to understanding the determinants of the rate and direction of innovative activity this paper reports on a recent survey of over 5000 american manufacturing sector firms on the extent to which innovators rely upon external sources of invention our results indicate that between 2007 and 2009 16 of manufacturing firms had innovated meaning had introduced a product that was new to the industry of these 49 report that their most important new product had originated from an outside source notably customers suppliers and technology specialists i e universities independent inventors and r d contractors we also compare the contribution of each source to innovation in the us economy although customers are the most common outside source inventions acquired from technology specialists tend to be the more economically significant in term of their gross commercial value as a group external sources of invention make a significant contribution to the overall rate of innovation in the economy innovation policies both public and private should pay careful attention to the external supply of invention and the efficiency of the mechanisms affecting the relationships between inventors and innovators

the wealth age relation among the aged aged people face the problem of allocating over the rest of their lifetimes the wealth that they have accumulated during their working years this problem is fairly complex because they are uncertain about the dates of their death and because they may wish to use their wealth to finance general consumption or hold it to meet emergencies leave estates or maintain power or status whether skilled at dynamic programming or not aged people effectively do make these decisions what are the results some studies of the entire lifetime pattern of saving and wealth tend to support the simple life cycle model in which the aged use up their wealth to help finance consumption harold lydall for example found saving rates to increase and then decrease with age in the whole population and to be negative for the group aged 65 and over guarded support for the theory was found by franco modigliani and albert ando in britain and by dorothy projector in the united states more recently a f shorrocks examined the lifetime pattern of wealth holding in estate tax data for a single cohort and found the hump pattern that is characteristic of life cycle saving other evidence on wealth holding runs contrary to this however in a study of estate tax returns in washington d c james d smith found that wealth increased with age among the aged after controlling for other demographic variables examining national estate tax data john brittain found wealth to increase with age in the united states and a b atkinson and a j harrison reported the same pattern in england and wales in a sample of tiaa annuity recipients analyzed by james mulanaphy over half reported that their total savings had increased during retirement and another quarter reported that their savings had remained about the same in this paper i examine wealth holding patterns among aged married couples using survey data representing the entire aged population of the united states in 1968 the statistical analysis serves as a test of the hypothesis that emerges from life cycle theory and provides some further exploration into the economic behavior of the aged i find that the aged tend to increase their wealth over time

cooperation between rivals informal know how trading it has long been recognized that it is difficult for an innovating firm to fully appropriate the benefits arising from its innovations and that desired research might therefore not be performed nelson 1959 pp 297 306 one sometimes possible solution to this dilemma is cooperative r d conducted by firms who share the costs and benefits of particular r d projects johnson 1973

international capital movements and the locomotive effect abstract in this paper we build a two country two good model in which domestic and foreign investment goods are perfect or imperfect substitutes and the utilization rate of capital is variable if investment goods are imperfect substitutes the model succeeds in mimicking the output cross country correlation in particular a country specific technological shock leads to an increase in output in the two countries which reveals a locomotive effect thus substitution elasticity between domestic and foreign investment goods is a key parameter of the international transmission of the business cycle in the model

reappraising the eclectic paradigm in an age of alliance capitalism this article discusses the implications of the advent of alliance capitalism for our theorizing about the determinants of mne activity in particular it argues that due to the increasing porosity of the boundaries of firms countries and markets the eclectic or oli paradigm of international production needs to consider more explicitly the competitive advantages arising from the way firms organize their inter firm transactions the growing interdependencies of many intermediate product markets and the widening of the portfolio of the assets of districts regions and countries to embrace the external economies of interdependent activities

health insurance availability and the retirement decision because individuals aged 55 64 face large and uncertain medical expenditures without the guarantee of public insurance coverage provided by medicare the availability of post retirement health insurance could be an important determinant in the retirement decisions of this group we investigate the effect of health insurance on retirement by focusing on state and federal continuation of coverage mandates which grant the retiree the right to continue purchasing health insurance through a previous employer for a specified number of months after leaving the firm we exploit variation in the timing and generosity of these laws to identify the effect of the availability of continuation coverage on retirement decisions using data on 55 64 year old males from the current population survey and the survey of income and program participation we find a sizeable and significant effect of continuation coverage on retirement one year of mandated continuation benefits raises retirement rates by 20 the effect appears to be uniform at all ages rather that larger near the age of medicare eligibility there is also a large increase in the insurance coverage of individuals who would have retired in the absence of continuation benefits our findings have important implications for policies which change the insurance coverage of early retirees such as national health insurance this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was b this abstract was borrowed from another version of this item

self employment and labor force participation of older males this longitudinal analysis of the labor market behavior of older urban white males in 1969 1971 and 1973 focuses on changes from wage and salary to self employment and changes from working to nonworking status in each two year transition approximately 4 percent of wage and salary workers switched to self employment controlling for a large number of economic and demographic variables the self employed were significantly more likely to continue to work partly by reducing their workweek to under 35 hours other significant predictors of continuing to work are good health years of schooling white collar occupation no expectation of a private pension and a workweek longer than 50 hours age is also important especially at the eligibility ages set by social security

the saving of the elderly in micro and macro data examination of household micro data on the elderly has generally concluded that they do not dissave significantly whereas estimates using aggregate macro data have shown that the presence of a large elderly population leads to a lower saving rate this paper shows that if interactions between generations are important one would not expect these estimates to be the same the paper presents new evidence that bequests are plausibly the source of this discrepancy examination of data from young households that have received or expect bequests confirms that bequests are indeed an important factor determining the saving of the young

the management and evaluation of technological programs and the dynamics of techno economic networks the case of the afme abstract the process of innovation and diffusion requires more and more interactions between the world of science and technology and the marketplace in order to describe these dynamics we define a techno economic network ten as a coordinated set of heterogeneous actors public laboratories technical research centers industrial firms users who participate collectively in the development and diffusion of innovations and via numerous interactions organize the relationships between scientifico technical research and the market although the word network is not systematically used there have been during the last years many more government interventions that we call technological programs aimed at supporting the emergence constitution and growth of tens which can attain the objectives corresponding to the program s pre defined goals based on an empirical study of the french agency for energy management afme this article presents a series of concepts and tools which are designed to describe the morphology of tens are they incomplete or chained convergent or dispersed long or short and to analyse their dynamics notions like anticipated networks breakthrough actions versus continuing operations intermediate results are presented examples of their use for the management and the evaluation of the technological programs are given

time to retire the effect of state fiscal policies on retirement decisions our research addresses the importance of state fiscal policies on the probability of retirement using a panel of individual tax return data results indicate that a one percentage point increase in the income or sales tax rate reduces the probability of retirement by about 8 7 percent the evidence suggests that state spending might also affect retirement decisions but magnitudes are inconclusive in general the results suggest that the income effect dominates that is higher tax rates at the state level reduce disposable income and decrease the probability of retiring results are similar in models examining single and married filers separately

financing innovations in uncertain networks filling in roadmap gaps in the semiconductor industry abstract complex technologies are often developed in inter organisational networks as actors try to reduce development costs and uncertainty about the viability of these innovations however as of to date it remains unclear how such innovations are financed collectively under conditions characterised by extreme uncertainty hence we explore how financial resources within innovation networks are mobilised and allocated this question is of particular importance to the development of system technologies that are viable only if all critical components are functional on time we explore this issue by reviewing the development of a radically new system technology for mass manufacturing microchips in the semiconductor industry in this industry technological roadmaps allow actors to identify critical components that still need to be developed these components are the so called roadmap gaps however suppliers can be reluctant to develop the required components at their own expense because of the high uncertainties involved in such cases providing financial support to component suppliers is a central task of innovation networks the empirical analysis shows that semiconductor manufacturers take both an individual and a collective approach to filling roadmap gaps this study contributes to prior research on innovation networks and financial management not only by identifying and clarifying these two approaches but also by revealing under which conditions they are used the findings are particularly relevant to scholars interested in the innovations of complex product systems cops

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

multinational experience and the creation of linkages with local firms evidence from the electronics industry the paper focuses on the nature and determinants of multinational firms creation of linkages with local firms with specific reference to the electronics industry the study of the recent evolution of international operations in this sector seems to highlight a relevant and somewhat generalisable pattern of industrial organisation and dynamics it is argued that the nature and intensity of multinational companies involvement into linkages with local counterparts are strongly influenced by a combination of factors that are partially inter dependent but still rely on different decision making centres on the one hand host countries long term investment policies in the field of human capital training and accumulation and on the other hand firms decisions to take roots in local contexts through the creation of foreign subsidiaries it is further suggested that human capital and subsidiaries will particularly favour the development of collaborative linkages with local firms compared to previous work of the authors on this subject this paper utilises an expanded and updated data set covering international operations of the top european and us electronics companies over the 1984 1995 period and attempts a more detailed and in depth analysis concerning the nature determinants and evolution in time of international growth strategies

do the sick retire early chronic illness asset accumulation and early retirement our objective is to determine how chronic illness affects asset accumulation and retirement previous studies have found that poor health leads to early retirement but those studies failed to look at the indirect impact of chronic illness on retirement using data from the health and retirement study we define an illness as chronic if the individual reports having asthma cancer heart disease stroke or diabetes for four or more years we first estimate how a chronic illness influences asset accumulation we then estimate how asset accumulation and current poor health influence retirement we observe that the vast majority of the chronically ill population do not report their general health to be poor nor do they report functional limitations in activities of daily living nevertheless our results indicate that chronic illness leads these people to accumulate fewer assets during their working years and consequently retire later neither researchers nor policy makers discussing the many critical issues

dynamics of the trade balance and the terms of trade the j curve the authors provide a theoretical interpretation of two features of international data the countercyclical movements in net exports and the tendency for the trade balance to be negatively correlated with current and future movements in terms of trade but positively correlated with past movements they document the same properties in a two country stochastic growth model in which trade fluctuations reflect in large part the dynamics of capital formation the authors find that their general equilibrium perspective is essential the relation between the trade balance and the terms of trade depends critically on the source of fluctuations copyright 1994 by american economic association

labor market shocks and retirement do government programs matter abstract this paper argues that labor market conditions are an important and often overlooked determinant of retirement transitions in our analysis we examine how the unemployment rate affects retirement and whether the social security ss system and unemployment insurance ui system influence how older workers respond to labor market shocks we use pooled cross sectional data from the march current population survey cps in our analysis we find that downturns in the labor market increase retirement transitions and that the magnitude of this effect is comparable to that associated with moderate changes in financial incentives to retire and to the threat of a health shock facing older workers interestingly retirements only increase in response to an economic downturn once workers become ss eligible suggesting that retirement benefits may help to alleviate the income loss associated with a weak labor market we also estimate the impact of ui generosity on retirement and find little consistent evidence of an effect this suggests that in some ways ss may serve as a more effective form of unemployment insurance for older workers than ui

early retirement provisions and the labor force behavior of older men evidence from canada we examine the sequential introduction of early retirement provisions to canada s two public pension plans these reforms provide a unique opportunity to assess the effect of public pension plan parameters on labor supply behavior free of the biases that potentially affect the simple time series or cross section inference presented in many previous studies we find that the reforms led to an increase in pension receipt but had little immediate effect on labor market behavior this is due to the fact that men who initially took advantage of the early retirement provisions would otherwise have had limited labor market participation

future social security entitlements and the retirement decision abstract a critical question for social security policy is how program incentives affect retirement behavior we use the health and retirement survey hrs to examine the impact of social security incentives on male retirement we implement forward looking models whereby individuals consider the incentives to work in all future years we find that forward looking incentive measures for social security are significant determinants of retirement we also find that private pension incentives have roughly similar effects our findings suggest that social security policies that increase the incentives to work at older ages can significantly reduce the labor force exit rate of older workers

the evolution of university industry government relationships during transition abstract this paper deals with the transformation of relationships between business and universities as reflected in government programmes and in the innovation activities of firms in a transition economy hungary the paper examines how government facilitates partnership between university and industry and how companies relate to universities its empirical basis is four pilot innovation surveys together with research and development statistics employing innovation surveys in an investigation of university business collaboration allows us to identify how strong a factor is the influence of universities in a given system the new government programmes tend to encourage closer links between public sector research and private sector expectations casual observations have shown that an innovation network can be created and exist if business firms are hungry for innovation hungarian business which is barely innovative or which is mainly involved in moderate innovation is still able to create limited research tasks mainly in experimental development and design in trials and in the tooling up process government programmes are moving in the right direction when they promote interaction in a national system of innovation however such interaction is still limited in the move towards a knowledge or learning based economy

business cycles and the exchange rate system some international evidence this paper investigates the differences in time series behavior of key economic aggregates under alternative exchange rate systems we use a postwar sample of 49 countries to compare the behavior of output consumption trade flows government consumption spending and real exchange rates under alternative exchange rate systems pegged floating and cooperative systems such as the ems we then examine evidence from two particular episodes involving canada and ireland of changes in the exchange rate system aside from greater variability of real exchange rates under flexible than under pegged nominal exchange rate systems we find little evidence of systematic differences in the behavior of macroeconomic aggregates or international trade flows under alternative exchange rate systems these results are of interest because a large class of theoretical models implies that the nominal exchange rate system has important effects on a number of macroeconomic quantities

in search of complementarity in innovation strategy internal r d and external knowledge acquisition empirical research on complementarity between organizational design decisions has traditionally focused on the question of existence of complementarity in this paper we take a broader approach to the issue combining a productivity and an adoption approach while including a search for contextual variables in the firms strategy that affects complementarity analysis of contextual variables is not only interesting per se but also improves the productivity test for the existence of complementarity we use our empirical methodology to analyze complementarity between innovation activities internal research and development r d and external knowledge acquisition our results suggest that internal r d and external knowledge acquisition are complementary innovation activities but that the degree of complementarity is sensitive to other elements of the firms strategic environment we identify reliance on basic r dthe importance of universities and research centers as an information source for the innovation processas an important contextual variable affecting complementarity between internal and external innovation activities

avoiding complexity catastrophe in coevolutionary pockets strategies for rugged landscapes can firms and coevolutionary groups suffer from too much interdependent complexity is complexity theory an alternative explanation to competitive selection for the emergent order apparent in coevolutionary industry groups the biologist stewart kauffman suggests a theory of complexity catastrophe offering universal principles explaining phenomena normally attributed to darwinian natural selection theory kauffman s complexity theory seems to apply equally well to firms in coevolutionary pockets based on complexity theory four kinds of complexity are identified kauffman s nk c model is positioned at the edge of chaos between complexity driven by newtonian simple rules and rule driven deterministic chaos kauffman s insight which is the basis of the findings in this paper is that complexity is both a consequence and a cause multicoevolutionary complexity in firms is defined by moving natural selection processes inside firms and down to a parts level of analysis in this instance porter s value chain level to focus on microstate activities by agents the assumptions of stochastically idiosyncratic microstates and coevolution in firms are analyzed competitive advantage as a dependent variable is defined in terms of nash equilibrium fitness levels this allows a translation of kauffman s theory to firms paying particular attention to 1 how value chain landscapes might be modeled 2 assumptions underlying kauffman s models making them amenable to firms and 3 a delineation of seven of kauffman s computational experiments as part of the translation possible parallels between the application of complexity catastrophe theory to coevolutionary pockets and studies by institutional theorists and social network analysts are discussed the models derive from spin glass microstate models resulting in boolean games kauffman s boolean statistical mechanics is introduced in developing the logic underlying the somewhat simplified nkm c model the model allows the use of computational experiments to better understand how the dependent variable value chain fitness is affected by changes in the number of internal interdependencies k the number of coevolutionary links with opponents c the size of the coevolutionary pocket s and the number of simultaneous adaptive changes among other things various computational experiments are presented that suggest strategic organizing approaches most likely to foster competitive advantage high or low nash equilibrium fitness levels are shown to result from internal and external coevolutionary densities as a function of links among value chain competencies within a firm and between a firm and an opponent complexity phenomena appear to suggest a number of expected and thus validating and surprising strategies with respect to complex organizational interdependencies for example moderate complexity fares best and external coevolutionary complexity sets an upper bound to advantages likely to be gained from internal complexity various complexity lessons are discussed models such as the nk c could offer insights into strategic organizing

who co operates for innovation and why an empirical analysis abstract in recent years there has been growing interest in co operative arrangements for innovation with some commentators arguing innovation is no longer the province of individual firms but depends increasingly on collective action this paper examines the response to the uk s version of the second european community innovation survey cis 2 to investigate the patterns of co operation between innovating firms and external partners the analysis shows the relationship between innovation and co operation is not straightforward from a subjective i e firm based perspective it is clear that most firms still develop their new products processes and services without forming formal co operative arrangements for innovation with other organisations however firms that engage in r d and that are attempting to introduce higher level innovations i e new to the market rather than new to the firm innovations are much more likely to engage in co operative arrangements for innovation consequently if an objective i e innovation based perspective is taken which weighs innovations by their significance then it is likely that a significant proportion of high level innovations are developed through co operative arrangements although unfortunately the cis 2 does not indicate the direct significance of these arrangements to the development of the innovations in summary the extent of co operative arrangements for innovation appears to depend on the type of firms being considered and on what is meant by innovation

the secrets of industry are in the air industrial cooperation and the organizational dynamics of the innovative firm abstract the purpose of this exploratory work is to contribute to the elaboration of an analytical framework appropriate to the study of the organizational forms involved in technological cooperation the approach used herein is one of formulating those properties of the process of integration and association of resources that are not based on the economics of transaction costs these properties suggest that the integration and the association of resources are necessary for the creation of technology but are also a source of irreversibility after having defined the concept of organizational balance of innovative firms which corresponds to the possibility of reconciling specific resources with the reversibility of technological capacity i will attempt to show that the forms of cooperation as much intra as inter firm constitute the basic principle of organization and functioning of innovative firms i shall be able thus to give a positive reading of technological cooperation on the basis of an economic analysis of organization

firms motivations for cooperative r d an empirical analysis of spanish firms abstract the aim of this paper is to analyze the motives that have caused industrial firms to cooperate in r d there are many theoretical works devoted to the theme but few empirical studies have been carried out with large samples to analyze the factors which determine why firms cooperate in r d we first review the reasons offered by the literature to explain technological cooperation with this allowing us to determine the conceptual framework and to propose some hypotheses we test these hypotheses with a sample of 1652 spanish firms that have carried out r d activities the results obtained suggest that firms motivations for cooperative r d are the complexity of technology and the fact that innovation is costly and uncertain we find that in order to undertake cooperative r d it is necessary to have certain internal capacities in this area with our results being supported by the theory of absorptive capacity however and by contrast with the results presented in other works questions related to market access and search for opportunities do not appear to exert an influence over cooperative r d besides the large sized firms resort more to cooperation and the reasons for cooperative r d differ as between large and small sized firms

economists perceptions versus managers decisions an experiment in transaction cost analysis are the perceptions of professional economists on transaction costs consistent with make or buy decisions made within firms the answer may have important implications for transaction cost research data on firms outsourcing during the new product development process are taken from a largescale survey of uk german and irish manufacturing plants and we test the consistency of these outsourcing decisions with the predictions derived from the transaction cost perceptions of a panel of economists little consistency is evident between actual outsourcing patterns and the predictions of the williamsonian transactions cost model derived from the panel of economists there is however evidence of a systematic pattern to the differences suggesting that a competence or resource based approach may be relevant to understanding firm outsourcing and that firms are adopting a strategic approach to managing their external relationships cambridge political economy society 2005 all rights reserved

the early retirement decision new empirical evidence on the influence of health many studies have examined the influence of health on retirement but there may be problems with the various health measures used a major criticism of the most frequently used variables is that they may reflect ex post rationalizations of retirement in this paper i examine a variety of health variables focusing directly on the health measurement issue as it relates to retirement research new measures of health are developed with individual self evaluations of health status unlike most previous findings the empirical results suggest that economic variables play a more important role than health in retirement decisions

internal r d expenditures and external technology sourcing abstract the paper examines the two way relationship between external r d activities and internal r d expenditures on a cross section of flemish r d active companies the analysis extends the classical explanatory variables like size diversification ownership structure and technological opportunities to include the impact of various external sourcing strategies r d cooperation and to a lesser extent r d contracted out are found to have a significant positive effect on internal r d but only if the companies have absorptive capacity in the form of a full time staffed r d department at the same time firms are found to be more frequently engaged in r d cooperation the more they spend on internal r d

trade interdependence and the international business cycle a stochastic general equilibrium model of the world economy is developed to analyze the contribution of trade interdependence to international business cycles we test some of the implications of the model using data from ten major industrial countries and a variety of detrending techniques to calculate the cyclical component of output we find that the significance of trade in the transmission of economic disturbances across countries is not robust to the choice of the detrending method in general the role of trade interdependence is moderate and seem to have been stronger in the period before 1973

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

firm level knowledge accumulation and regional dynamics two bodies of literature have contributed significantly to our insight into the forces driving competitiveness and economic growth regional agglomeration studies emphasise the favourable impact of geographical proximity on regional economic performance particularly through knowledge spillovers however the firms that constitute those agglomerations largely remain black boxes in contrast studies dealing with technological learning explain economic performance at firm level without systematically taking account of the effects of geographical proximity the aim of the paper is to propose a possible way to bridge this gap this contributes to our understanding of the determinants of economic growth in industrial clusters an empirical illustration of a capital goods cluster is elaborated

high tech start up firm survival originating from a combined use of internal resources although various streams in the existing literature on the resource based view rbv of the firm argue that firm survival and performance can benefit from a combined use of internal resources relatively limited empirical evidence is provided that supports this argument to fill this gap in the literature in this article we focus on how combinations of internal resources affect the survival chance of technology based start ups by using a unique dataset from a high tech park in beijing china empirical results show that firms interconnected internal resources exert a significant influence on these firms survival chance our findings imply that the survival of new technology based start ups benefits from the synergetic effect of combining resources in detail the data support the hypothesis that the combined use of r d resources internal financial resources and scientifically skilled employees as posited by the rbv has an amplifying effect on the chances to survive of high tech start ups

innovation and cooperation in the small firm sector evidence from northern britain freel m s and harrison r t 2006 innovation and cooperation in the small firm sector evidence from northern britain regional studies 40 289 305 over the last 20 years network based models of innovation led economic development have grown increasingly popular to both the polity and the academy in contrast to earlier linear conceptions innovation is viewed as a systemic phenomenon in which interactive learning and cooperative entrepreneurship are fundamental the way that systems and in turn networks are usually defined is by the volume and characteristics of the linkages that bind them together accordingly drawing upon a recent survey of small firms in scotland and northern england 1347 responses the paper is concerned with mapping the extent of small firm innovation related networking and understanding the unique contribution such networks make to the successful introduction of new products and processes importantly it investigated the impact of networking on innovation in both manu

is there a retirement savings puzzle in this paper we ask whether households are saving enough for their retirement we use data on income expenditure and expenditure components to analyse patterns of behaviour at and around the time of retirement for successive date of birth cohorts we compare periods of unemployment to periods of retirement and separate expenditures into categories reflecting work related expenditures basic necessities and other goods we find that income typically falls by more at unemployment than retirement but the reverse is true for expenditure we observe falls in expenditure at retirement for all expenditure categories using a stochastic life cycle model including mortality rates we assess the anticipated impact of retirement on consumption against that of unemployment the inter relationship between goods and leisure explains a large part of the persistent fall in expenditure at retirement we argue that the only way in which the life cycle hypothesis could be reconciled with the remaining unanticipated dip in consumption would be with the systematic arrival of unexpected adverse information at the time of retirement
