is firm specific innovation associated with greater value appropriation the roles of environmental dynamism and technological diversity abstract this paper extends the resource based theory of the firm to examine the contingencies that either intensify or reduce the relationship between firm specific innovation and value appropriation based on a large scale analysis of a sample of us manufacturing firms we found that greater innovation rents appropriation is associated with an increase in firm specificity of its innovative knowledge but the positive relationship between firm specific innovations and firm value appropriation tends to decrease when the product or technology market is highly dynamic further under high environmental dynamism firms should increase the diversity in their knowledge composition in order to mitigate the risk of value erosion associated with firm specific innovations

the value of online banking to small and medium sized enterprises evidence from firms operating in the uae free trade zones abstractthis study estimates the willingness to pay of small and medium sized enterprises smes for a business online banking services the estimation utilizes a contingent valuation method employing data from 400 smes in the united arab emirates free zones an interval regression model is used to identify company characteristics affecting wtp the results indicate an average wtp for online banking of 518 50 per month firms engaging in international trade value these services at least 10 more than those with only domestic operations other variables that significantly affect wtp include number of employees and the transportation cost of using traditional branch banking

information technology effects on firm performance as measured by tobin s q despite increasing anecdotal evidence that information technology it assets contribute to firm performance and future growth potential of firms the empirical results relating it investments to firm performance measures have been equivocal however the bulk of the studies have relied exclusively on accounting based measures of firm performance which largely tend to ignore it s contribution to performance dimensions such as strategic flexibility and intangible value in this paper we use tobin s q a financial market based measure of firm performance and examine the association between it investments and firm q values after controlling for a variety of industry factors and firm specific variables the results based on data from 1988 1993 indicate that in all of the five years the inclusion of the it expenditure variable in the model increased the variance explained in q significantly the results also showed that for all five years it investments had a significantly positive association with tobin s q value our results are consistent with the notion that it contributes to a firm s future performance potential which a forward looking measure such as the q is better able to capture

applying contingent valuation in china to measure the total economic value of restoring ecosystem services in ejina region abstract this paper reports an attempt to apply the contingent valuation method cvm in rural china the cvm was used to obtain estimates of willingness to pay for restoring ejina ecosystem services in our survey we used a payment card format and a 12 page survey booklet with maps depicting the reasons why ejina ecosystem deteriorated the means by which ecosystem services could be restored from their current level we used an in person interview along with the survey booklet we employed a parametric model to estimate the benefits of restoring ejina ecosystem results from 700 in person interviews indicate that households would pay an average of 19 37 rmb per year with 20 78 per household for the main river area and 16 41 per household for the rest of hei basin the aggregate benefit to residents of the hei basin is 8 84 million annually for 20 years taking into account an environmental discount rate calculated by using respondent s equivalent utility between periodical payments and lump sum payments the present value of aggregate benefit of restoring ejina ecosystem is 55 33 million these results suggest that the general public in hei valley would be willing to pay to restore the ejina ecosystem although this amount is substantially less than the estimated costs of restoration

interval estimates of non market resource values from referendum contingent valuation surveys contingent valuation methods cvm have attracted considerable attention in recent years as researchers have begun to resort to survey methods to elicit individual values for non market goods such as environmental resources or public goods cummings brookshire and schulze 1986 and mitchell and carson 1989 offer comprehensive assessments of these methods cvm survey questions come in a variety of forms one format which has proven to be popular is called the discrete choice or take it or leave it referendum or closedended question originally implemented in the literature by bishop and heberlein 1979 since respondents find it very difficult to identify precisely their true point value of access to some resource or public good open ended valuation questions can be unreliable or can discourage response in contrast most people are familiar with being confronted by a posted price for a good and with deciding whether or not they would buy at that price this is the strategy behind discrete choice cvm questions a different hypothetical price is offered to each respondent and by their yes no response to the question of whether they would be willing to pay this price the researcher gains information about their true underlying point value one persistent difficulty with the econometric techniques that are currently used most widely to analyze referendum contingent valuation data is the absence of confidence intervals for the ultimate value estimates early empirical applications approximate mean valuations using a truncated mean based on a logit model with the upper limit being the highest bid value in the sample unfortunately the variance of this estimated mean cannot easily be recovered from the numerical integration procedure commonly used to calculate the

how do policies for efficient energy use in the household sector induce energy efficiency innovation an evaluation of european countries abstract research on innovation induced by climate mitigation policy has been focused predominantly on the supply side of the energy system despite considerable climate mitigation potential on the demand side less attention is given to the innovation effect of policies addressing the household sector based on a comprehensive data set including 550 policy measures over 30 years 1980 2009 and covering 21 european countries we find based on econometric estimations that policies targeting efficient energy use in the household sector significantly increase the number of patented energy efficiency inventions a comparison of the different policy types reveals a particularly strong influence from financial subsidies and energy labels the results indicate that policies supporting early market adoption of energy efficient technologies are effective in fostering innovation

family firms and r d behavior new evidence from a large scale survey abstract this paper analyzes how founders and their families influence r d intensity information on r d comes from a large scale bi annual survey among listed german firms we find that r d intensity is higher in firms that are actively managed by the family the impact of family control via voting rights is negative but mostly not significant while this negative family control effect is in line with hitherto existing literature the positive impact of family management is surprising indeed this positive effect disappears if we follow previous research and use r d information from financial statements we show that this puzzling result is related to corporate opacity opaque family managed firms report too conservative r d expenditures especially if they face financial constraints this leads to an under estimation of r d intensity in these firms if accounting figures are used

the relative effectiveness of patents and secrecy for appropriation abstract changes in patent law global competition and the rise of several new technologies suggest that patents could be of greater value than secrecy for many innovative firms particularly small firms that are unable to use market power or other factors to appropriate their investments in innovation data from the 1993 european community innovation survey cis for up to 2849 r d performing firms is analysed to determine the relative importance of secrecy vs patents this particular combination of appropriation methods is interesting because secrecy can act as a mutually exclusive alternative to patents the results show that a higher percentage of firms in all size classes rate secrecy as more valuable than patents however ordered logit regressions show that the probability that a firm rates secrecy as more valuable than patents declines with an increase in firm size for product innovations while there is no relationship for process innovations the firm s r d intensity has no effect on the relative value of secrecy vs patents there is weak evidence to show that participation in cooperative r d increases the value of patents over secrecy for product innovations the results are relevant to ongoing debates over changes to the patent system and the need for policies to encourage small firms to patent more

new evidence on sex segregation and sex differences in wages from matched employee employer data we use new matched employer employee data to estimate the contributions of sex segregation and wage differences by sex within occupation industry establishment and occupation establishment cells to the overall sex gap in wages in contrast to earlier data used to study this question our data cover all industries and occupations across all regions of the united states we find that segregation of women into lower paying occupations industries establishments and occupations within establishments accounts for a sizable fraction of the sex gap in wages nonetheless approximately one half of the sex gap in wages remains attributable to the individual s sex

on the trade off between the future benefits and riskiness of r d a bondholders perspective abstract existing studies on the value relevance of r d tend to overstate the r d benefits and shed little light on the trade off between the r d benefits mean effect and their riskiness variance effect this study shows that the variance effect of r d is on average more significant than their mean effect in bond valuation hence for creditors the r d risk dominates their benefits furthermore this study documents that r d measures alone explain approximately 80 of cross sectional variations in bond ratings and risk premium these findings contribute to the debate over r d accounting and the bond pricing literature

contingent credibility the impact of investment treaty violations on foreign direct investment during the past few decades governments have signed nearly 2 700 bilateral investment treaties bits with one another in an attempt to attract greater levels of foreign direct investment fdi by signing bits which contain strong enforcement provisions investment seeking governments are thought to more credibly commit to protecting whatever fdi they receive which in turn should lead to increased confidence among investors and ultimately greater fdi inflows our unique argument is that the ability of bits to increase fdi is contingent on the subsequent good behavior of the governments who sign them bits should increase fdi only if governments actually follow through on their bit commitments that is if they comply with the treaties bits allow investors to pursue alleged treaty violations through arbitration venues like the international centre for the settlement of investment disputes icsid a heavily utilized and widely observed arbitral institution that is part of the world bank being taken before icsid then conveys negative information about a host country s behavior to the broader investment community which could result in a sizeable loss of future fdi into that country we test these contingent effects of bits using cross sectional time series analyses on all non oecd countries during a period spanning 1984 2007 we find that bits do increase fdi into countries that sign them but only if those countries are not subsequently challenged before icsid on the other hand governments suffer notable losses of fdi when they are taken before icsid and suffer even greater losses when they lose an icsid dispute

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

patents and the survival of internet related ipos abstract we examine the effect of patenting on the survival prospects of 356 internet related firms that made an initial public offering on the nasdaq at the height of the stock market bubble of the late 1990s by march 2005 almost 2 3 of these firms had delisted from the exchange changes in the legal environment in the us in the 1990s made it much easier to obtain patents on software and ultimately on business methods though less than 1 2 of the firms in our sample obtained or attempted to obtain patents for those that did we hypothesize that patents conferred competitive advantages that translate into higher probability of survival though they may also simply be a signal of firm quality controlling for other determinants of firm survival patenting is positively associated with survival quite different processes appear to govern exit via acquisition compared to exit via delisting from the exchange due to business failure firms that applied for more patents were less likely to be acquired though if they obtain unusually highly cited patents they may be a more attractive acquisition target these findings do generally not hold true for business method patents which do not appear to confer a survival advantage

intellectual capital in a q theory of ag biotech mergers tobin s q theory of investment has been linked to firm merger activity by jovanovic and rousseau jr they showed that firms with higher q values that is the ratio of market to book values tend to be the ones buying other firms and not the ones being acquired market values should theoretically equal book values a firm s assets as they appear on the balance sheet equal to their cost less accumulated depreciation in reality book value often differs from market value especially in knowledge intensive industries indicating the premium above measurable assets that shareholders are willing to pay for a company s unique combination of market position tangible and intangible capital goodwill and other favorable characteristics firms with greater q values are in a position to acquire more capital possibly through mergers and acquisitions to make further use of their advantages this article extends the jr analysis to consider the role of intellectual capital in merger activity we analyze the connection between intangible capital and the q theory of mergers in the agricultural biotechnology ag biotech industry this industry underwent significant technological change beginning in the late 1980s as new biotechnology techniques were integrated with plant breeding and other agricultural practices the number of patent applications in the field grew from less than a 100 a year in the late 1980s to more than 500 applications per year by the mid 1990s bennett et al along with this technological change

entry and patenting in the software industry to what extent are firms kept out of a market by patents covering related technologies do patents held by potential entrants make it easier to enter markets we estimate the empirical relationship between market entry and patents for 27 narrowly defined categories of software products during the period 1990 2004 controlling for demand market structure average patent quality and other factors we find that a 10 increase in the number of patents relevant to market reduces the rate of entry by 3 8 and this relationship intensified following expansions in the patentability of software in the mid 1990s however potential entrants with patent applications relevant to a market are more likely to enter it finally patents appear to substitute for complementary assets in the entry process because patents have both greater entry deterring and entry promoting effects for firms without prior experience in other markets this paper was accepted by bruno cassiman business strategy

introduction the global economy fdi and the regime for investment the world economy has maintained or enhanced its integration in the past decade even in the face of the global financial crisis a large part of this globalization has been driven by capital flows this symposium focuses on one element of these capital flows foreign direct investment fdi and on the regime in place to safeguard and promote such investments around the globe the articles by allee and peinhardt and simmons focus on the nature and evolution of the bilateral investment treaties bits that have been developed to protect such investments and that have proliferated since the 1990s the final article by buthe and milner turns its attention to the ways in which international trade agreements affect fdi the comparison between the investment and trade agreements is instructive since they seem to have different effects fdi has become one of the most important economic flows in the global economy it is a critical source of capital for developing countries and remains a significant source of investment in the developed world fdi has grown in part because countries changed their policies toward it dramatically after the 1980s governments in developing countries made unilateral policy changes that opened up markets across the globe and increased competition among countries for fdi

how do patent laws influence innovation evidence from nineteenth century world fairs studies of innovation have focused on the effects of patent laws on the number of innovations but have ignored effects on the direction of technological change this paper introduces a new dataset of close to fifteen thousand innovations at the crystal palace world s fair in 1851 and at the centennial exhibition in 1876 to examine the effects of patent laws on the direction of innovation the paper tests the following argument if innovative activity is motivated by expected profits and if the effectiveness of patent protection varies across industries then innovation in countries without patent laws should focus on industries where alternative mechanisms to protect intellectual property are effective analyses of exhibition data for 12 countries in 1851 and 10 countries in 1876 indicate that inventors in countries without patent laws focused on a small set of industries where patents were less important while innovation in countries with patent laws appears to be much more diversified these findings suggest that patents help to determine the direction of technical change and that the adoption of patent laws in countries without such laws may alter existing patterns of comparative advantage across countries jel d2 k11 l51 no 014

improving patent valuations for management purposes validating new indicators by analyzing application rationales abstract this paper analyzes the validity of so far untested indicators of patent value to enhance the quality of patent assessments using indicators at the corporate level the article expands the theory by eliciting patent attorneys filing rationales to maximize profits from protecting intellectual property to inspire the computation of new value indicators including patent full texts then based on a newly compiled data set consisting of 813 ep patents the probability of an opposition against a patent is modeled by established and new value indicators the results show that accelerated examination requests and qualified word counts enhance the quality of existing valuation methods

value implications of investments in information technology the year 2000 y2k countdown provided a uniquely visible instance of spending on information technology it by u s companies with public attention riveted on potential y2k malfunctions managers were forced to evaluate their it and make decisions about whether to modify or replace existing systems in the aftermath of y2k critics charged that the problem was overblown and that companies overspent on it in contrast we posit in this paper that efforts companies made to renew and upgrade their it may have positioned them to take advantage of new e business applications as y2k approached managers could invest opportunistically in it which would enable them to connect with customers and suppliers in new ways contrary to the alleged overspending we find that firm value increased on average with y2k spending by fortune 1000 companies in particular higher firm value and subsequent earnings were associated with y2k spending for firms in industries where it was considered to have a transforming influence altering traditional ways of doing business by redefining business processes and relationships we also test whether the positive association between firm value and y2k spending diminished with y2k spending by industry peer firms but we do not find support for this relative investment hypothesis

the diffusion of regime contention in european democratization 1830 1940 this article goes beyond the established literature s focus on domestic conditions by examining the impact of external impulses on european democratization from 1830 to 1940 specifically it analyzes the diffusion of regime conflict that arose from the cross national spread of situational judgments about the feasibility of political change striking precedents of regime collapse such as the overthrow of french kings in 1830 and 1848 tended to produce dramatic waves of political contention across europe but because the actual distribution of power in polities that experienced such externally stimulated episodes of regime contention often differed from the front runner these conflicts produced various types of results the article distinguishes four outcomes of diffusion namely a successful replication b preemptive reform c abortive replication and d blockage of replication efforts the latter two outcomes help explain why in european history not only did political liberalism and democracy

the impact of environmentally friendly innovations on value added while recent literature has focused on explaining the determinants of green innovations it is not well understood how such innovations affect performance to analyse the relationship between green innovation and performance new industry level panel data were exploited these include 12 oecd countries the whole manufacturing sector and a period of 30 years the results show that green inventions are u shape related to performance however the turning point is quite high and hence only relevant for a few industries this indicates that given the current level of green promotion market incentives alone are not sufficient to allow the green invention activities of industries to rise considerably to verify these results and to get a better understanding of the mechanisms in the green market we finally made several interviews with multinational firms that have a good understanding of what happens on the global market of green innovation

when the claim hits bilateral investment treaties and bounded rational learning using the international investment regime as its point of departure the article applies notions of bounded rationality to the study of economic diplomacy through a multimethod approach it shows that developing countries often ignored the risks of bilateral investment treaties bit s until they themselves became subject to an investment treaty claim thus the behavior of developing country governments with regard to the international investment regime is consistent with that routinely observed for individuals in experiments and field studies they tend to ignore high impact low probability risks if they cannot bring specific vivid instances to mind

industry effects and appropriability measures in the stock market s valuation of r d and patents this paper examines the stock market s valuation of a firm s innovative activity we estimate the market s relative valuation of firms tangible and intangible assets focusing on knowledge capital in the form of accumulated stocks of r d and patents we tried to improve upon our estimates of the stock market s valuation of knowledge capital embodied in such stocks by bringing in measures of the appropriability environment facing a firm from the yale survey on industrial research and development the responses to survey questions about the effectiveness of patents as a mechanism for protecting the returns from innovation turn out to be of some use there is evidence of an interaction between industry level measures of the effectiveness of patents and the market s valuation of a firm s past r d and patenting performance as well as its current r d moves we find no evidence however that other appropriability mechanisms differ enough across industries to leave measurable traces in our data the structure of the yale survey makes it possible to estimate the sampling error in the appropriability measures derived from it this information was used by us in an errors in variables context but with little success in the absence of r d variables our estimates imply that a two standard deviation increase in our index of patent effectiveness would raise the value of a patent held by our average firm from 0 4 million to 1 0 million when r d variables are introduced into the equations the patents variables become insignificant r d expenditures are a better measure of input to the innovative function of firms than patents are of its output but we estimate that the same experiment would induce changes in q of between 10 and 27 percent for the average firm approximately doubling the market s valuation of this kind of capital this abstract was borrowed from another version of this item

learning from others the diffusion of hospital financing reforms in oecd countries the increase in health care expenditures is a major problem of all welfare states to counter this trend since the early 1980s most oecd countries have changed the way hospitals are financed although these reforms are certainly linked to country specific factors the authors main argument is that they are in part due to a diffusion process policy change in one country is influenced by previous changes in other countries more specifically the authors argue that policy makers learn from the experience of others using an original data set and event history methods to test arguments their results show that policy change is more likely when the existing policy is ineffective and when the experience of other countries suggests that the reform leads to the desired results in addition the authors find that the effects of learning grow over time and that early adopters tend to be countries with few veto players

the benefits and costs of riparian analysis habitat preservation a willingness to accept willingness to pay contingent valuation approach abstract the contingent valuation method cvm was used to obtain the willingness to pay wtp of households in the contiguous area of the garonne river near toulouse france and the willingness to accept wta of households that currently own land on the banks of the river to provide a strip of riparian land for habitat preservation results for the wtp study indicated a relatively large difference in wtp between open and closed ended responses when corrected for the substantial number of 0 observations the wtp was reduced by about half the wta results were constrained by relatively few positive responses however the value given by farmers who indicated a positive wta appears consistent with revenues generated from crops moreover many farmers who were already providing habitat preservation indicated a zero minimum wta although the small number of wta responses severely limits the ability to draw definitive conclusions a comparison of the derived benefits wtp and costs wta was made which appeared to suggest the possibility of a favorable a benefit cost ratio

post entry competition in the plain paper copier market this paper reviews events in the plain paper copier ppc market immediately after xerox s monopoly ended xerox s behavior and that of a flood of ppc entrants are viewed through the lens of recent advances in the theory of entry and entry deterrence the events of the early post entry period also cast some interesting light on the theory of technological competition the modern theory of entry deterrence rests on a simple if not obvious proposition the socially worst industry performance is after entry the more monopolies there will be since the interests of the entrant and society are opposed once entry has occurred a series of papers have considered endogenous changes in the conditions of competition monopolists who make their industry more competitive conditional on entry in order to deter potential entrants there are two distinct steps in the entry deterrence argument first it must be possible for events during the monopoly period to affect postentry competition some intertemporal complication must be present either in costs or in firm specific demand if the state of the industry at the time of entry is to form important initial conditions for competition second the monopolist must find it profitable to manipulate the initial conditions by some pre entry action the general theoretical questions of entry and deterrence have been cast in quite specific terms for the problem of technological competition one view emphasizes the arrow effect kenneth arrow 1962 jennifer reinganum 1983 drew fudenberg and jean tirole because any innovation destroys some of the rents to older products and processes incumbent monopolists have a smaller incentive to innovate than potential entrants another view richard schmalensee 1983 richard gilbert and david newbery 1982 points out that the incumbent s losses from entrant s innovation create a motive for preemptive r d product introduction or patenting if incumbents are leaders and entrants followers the second view will hold independent of technology note that the difference is over the profitability of entry deterring strategies in both views the presence of valuable assets like patents or secrets provides the necessary intertemporal link events in the ppc market during the time of xerox s monopoly did have a substantial impact on the nature of competition in the early postentry period an arrow effect is evident as are other equilibrium explanations of xerox s rapid decline the alternative explanation that xerox was fat is also considered below

why do industries coagglomerate how marshallian externalities differ by industry and have evolved over time abstract the fact that firms benefit from close proximity to other firms with which they can exchange inputs skilled labor or know how helps explain why many industrial clusters are so successful studying the evolution of coagglomeration patterns we show that the type of agglomeration that benefits firms has drastically changed over the course of a century and differs markedly across industries whereas at the beginning of the twentieth century industries tended to colocate with their value chain partners in more recent decades the importance of this channel has declined and colocation seems to be driven more by similarities in industries skill requirements by calculating industry specific marshallian agglomeration forces we are able to show that today skill sharing is the most salient motive behind the location choices of services whereas value chain linkages still explain much of the colocation patterns in manufacturing moreover the estimated degrees to which labor and input output linkages are reflected in an industry s coagglomeration patterns help improve predictions of city industry employment growth

companies learning to innovate in recessions abstract innovating in downturns can affect corporate success by improving a firm s position relative to competitors during the recovery period however increased uncertainty and more binding financial constraints complicate such innovation activity i find that past experience with innovation during recessions improves a firm s ability to invest in r d when a new downturn hits this result holds controlling for traditional drivers of innovation as cumulated innovations and financial constraints as well as mitigating endogeneity and selection concerns moreover i find that past experience with innovation during recessions is beneficial to patent outcomes after a new recession overall the paper provides novel evidence on how business cycles shape innovative capabilities

the dynamics of innovative activity and competitive advantage the case of australian retail banking 1981 to 1995 this study examines the adoption of new products and processes in the australian retail banking industry over the 1981 to 1995 period our analysis demonstrates that the vast majority of observed innovative activity was based on ideas sourced from outside the focal firm and that innovations diffused very quickly across competing banks as such there were no periods during which any bank had proprietary possession of a major product or process innovation we therefore ask how the banks innovative activity could affect their relative financial performance positions we answer this question by developing a set of hypotheses that relate specific features of their histories of innovative activity to their current financial performance these hypotheses are tested using a detailed data set describing 1 297 modifications made to products and services distribution technologies and back office processes within a sample of australian retail banks over the sample period our results provide support for the general position that establishing an attractive competitive position depends on the specific history of a firm s innovative activity banks that undertook more innovative activity that were more consistent in that activity and whose composition of activity was somewhat differentiated from the industry norm tended to display superior financial performance rather than looking solely for internally generated inimitable innovations to deliver competitive advantage these results suggest that active and consistent innovative activity that is somewhat differentiated from competitors can also deliver superior financial performance

the willingness to pay by households for improved reliability of electricity service in north cyprus abstract this research examines households willingness to pay wtp for an improved electricity service households wtp is estimated using the payment ladder contingent valuation cv data from 350 in person interviews in north cyprus in order to avoid the cost of outages households are willing to incur a 13 8 increase in their monthly electricity bill a cost benefit analysis cba indicates that the annualized economic benefits of improved reliability of the electricity service would be approximately usd 35 6 million for the residential sector this figure is more than enough to finance the investments needed to completely eradicate any electricity outages in addition the fuel savings from substituting the generation of the new plants for the old plants would yield about usd 32 9 million per year in fuel savings hence a change from the current low reliability policy to one of providing a high quality service would yield an economic net present value to the residents of north cyprus of twice the investment costs or usd 173 3 million within five years

competing for capital the diffusion of bilateral investment treaties 1960 2000 over the past forty five years bilateral investment treaties bits have become the most important international legal mechanism for the encouragement and governance of foreign direct investment the proliferation of bits during the past two decades in particular has been phenomenal these intergovernmental treaties typically grant extensive rights to foreign investors including protection of contractual rights and the right to international arbitration in the event of an investment dispute how can we explain the widespread adoption of bits we argue that the spread of bits is driven by international competition among potential host countries typically developing countries for foreign direct investment we propose a set of hypotheses that derive from such an explanation and develop a set of empirical tests that rely on network measures of economic competition as well as more indirect evidence of competitive pressures on the host to sign bits the evidence suggests that potential hosts are more likely to sign bits when their competitors have done so we find some evidence that coercion and learning play a role but less support for cultural explanations based on emulation our main finding is that the diffusion of bits is associated with competitive economic pressures among developing countries to capture a share of foreign investment we are agnostic at this point about the benefits of this competition for development for useful comments on earlier drafts of this article we thank bill bernhard bear braumoeller frank dobbin robert franzese jeffry frieden geoffrey garrett tom ginsburg jude hays lisa martin bob pahre mark ramsayer steven ratner susan rose ackerman and john sides for research assistance we thank elizabeth burden raechel groom and alexander noonan

imitation costs and patents an empirical study it has long been recognised that the costs of imitating new products have an important effect on the incentives for innovation in a market economy as arrow i962 and others have pointed out if firms can imitate an innovation at a cost that is substantially below the cost to the innovator of developing the innovation there may be little or no incentive for the innovator to carry out the innovation in their discussions of the innovation process economists frequently have called attention to the major role played by the costs of imitation but there has been little or no attempt to measure these costs to test various hypotheses concerning the factors influencing them or to estimate their effects in this paper we report some findings of what seems to be the first study of this topic in addition we present data regarding the effects of patents on imitation costs and on the rate of innovation

patenting by manufacturing firms in india its production and impact this paper attempts to simultaneously study the production and impact of patenting in a less developed country using panel firm level data for the period 1975 79 for india the authors results suggest that despite the limited protection of intellectual property rights in india patenting is associated with a significant increase in total factor productivity growth at the firm level after controlling for unobserved fixed firm effects r d manpower appears to be the only input that significantly influences the probability of patenting copyright 1989 by blackwell publishing ltd

the value of intellectual property rights to firms and society economists view intellectual property rights iprs as policy tools for encouraging innovation but they recognize that they can also inhibit competition there are many types of iprs and institutions concerned with their administration we begin by outlining how these complex and varied rights are supposed to work and how they interact with other characteristics of firms and markets we then survey the available literature on patents trade marks and copyright to assess the value of these iprs to firms and the costs to firms of acquiring and defending their rights the paper concludes with suggestions for topics requiring further research to inform public policy better

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

respondent direct experience and contingent willingness to pay for new commodities a switching endogenous interval regression analysis most environmental economists argue that direct experience with the good being valuated or with similar goods is a precondition for providing valid willingness to pay wtp responses to contingent valuation questions two questions are posed in this article the first is whether previous use experience of a resource sene nature reserve similar to that being valuated future nature reserves and located in the same geographical area gulf of morbihan impacts on wtp the second is whether accounting for the endogeneity of direct experience matters in the estimation of wtp we find that respondents who have not experienced the sene nature reserve provide value estimates that are statistically comparable to that of respondents who have experienced it our assumption is that respondents have acquired sufficient and adequate experience of future nature reserves from the questionnaire that experience obtained by experiencing the sene nature reserve was not necessary for making a valid value formulation hen

willingness to pay for environmental improvements in a large city evidence from the spike model and from a non parametric approach in this paper the contingent valuation method cvm is applied in order toestimate the social benefits of a set of environmental and urbanimprovements planned for the waterfront of the city of valencia spain asa consequence of the expansion and restructuring of its trading port asthe data show a high rate of zero responses we applied the spike model one of the most recent models in cvm literature since traditional models logit and probit are not suitable given the characteristics of our data the non parametric approach is also applied in order to test the validity ofthe spike model the results show certain similarities between the spikemodel and the non parametric approach

dynamic competition in technological investments an empirical examination of the lcd panel industry abstract when are technological laggards more likely to try to catch up with leaders we offer empirical evidence on firm level data of plant investments in the tft lcd panel industry where technological competition has been intense and dynamic we find that the followers level of technology has a non monotonic effect on technology improving investments with intermediate followers the most apt to invest in catch ups this result is a puzzle given the existing theory on technology race we also find that followers catch up investments increase with the capacity of the leader that employs the state of the art technology these results are robust to variations in specification and alternative accounts of effects we discuss our findings and contributions in light of the technology race literature

patent quality and research productivity measuring innovation with multiple indicators we analyse the determinants of the decline in research productivity using panel data on manufacturing firms in the us for the period 1980 93 we focus on three factors the level of demand the quality of patents and technological exhaustion we develop an index of patent quality using detailed patent information and show that using multiple indicators substantially reduces the measured variance in quality research productivity at the firm level is inversely related to patent quality and the level of demand as predicted by theory and patent quality is positively associated with the stock market value of firms
