innovation and imitation in a duopoly in a duopoly where one firm has the idea for a non patentable innovation the expected profits from the innovation will not be a monotonic function of the cost of innovating furthermore a costly innovation may be undertaken where an inexpensive one would not have been all other things being equal

spatial targeting of payments for environmental services a tool for boosting conservation benefits abstract payments for environmental services pes have become an increasingly popular market based instrument to translate external non market environmental services into financial incentives for landowners to preserve the ecosystems that provide the services however lack of spatial differentiation in the targeting mechanism may lead to efficiency losses addressing this challenge we construct an applied site selection tool which takes into account three variables that vary in space environmental services provided risks of losing those services and participation costs using data from costa rica s nicoya peninsula we empirically test the tool s potential to increase the financial efficiency of the forest focused pes program in place results show that given a fixed budget efficiency increases radically if per hectare payments are aligned to landowners heterogeneity in participation costs involving opportunity transaction and direct costs of protection respectively selecting sites based on environmental service potential also moderately increases efficiency overall additionality could in the best case be doubled but remains generally limited due to current low deforestation risks prevailing in costa rica to take advantage of the high efficiency potentials of flexible payments we propose inverse auction systems as a cost effective approach for the determination of micro level participation costs

energy conservation more effective with rebound policy this article sketches the problem of indirect energy use effects also known as rebound of energy conservation there is widespread support for energy conservation especially when it is voluntary as this seems a cheap way to realize environmental and energy climate goals however this overlooks the phenomenon of rebound the topic of energy rebound has mainly attracted attention from energy analysts but has been surprisingly neglected in environmental economics even though economists generally are concerned with indirect or economy wide impacts of technical change and policies this paper presents definitions and interpretations of energy and environmental rebound as well as four fundamental reasons for the existence of the rebound phenomenon it further offers the most complete list of rebound pathways or mechanisms available in the literature in addition it discusses empirical estimates of rebound and addresses the implications of uncertainties and difficulties in assessing rebound suggestions are offered for strategies and public policies to contain rebound it is advised that rebound evaluation is an essential part of environmental policy and project assessments as opposed to earlier studies this paper stresses the relevance of the distinction between energy conservation resulting from autonomous demand changes and from efficiency improvements in technology equipment in addition it argues that rebound is especially relevant for developing countries

the effects of regulation on research and development theory and evidence while other aspects of the effects of regulation on resource allocation have received considerable attention the impact of regulation on the innovative p ropensities of regulated firms has generated only limited and somewha t tenuous evidence accordingly this article investigates the effect s of regulation and firm structure on research and development r d expenditures a simple model of the behavior of a firm under a rate o f return regulation suggests that both the stringency of the allowed rate of return constraint and the inclusion or exclusion of r d in a firm s rate base will be key determinants of firm level r d expenditu res the empirical results strongly support the theoretical model copyright 1988 by the university of chicago

to value or not to value that is not the question abstract should we reject money when we value nature like most environmentalists ecological economists are increasingly divided on this question synthesizing political ecology with ecological economics we argue that this way of framing the question is limited we propose a reformulation of the question into when and how to value with money and under what conditions we recommend four criteria for a sound choice environmental improvement distributive justice and equality maintenance of plural value articulating institutions and confronting commodification under neo liberalism we call for due attention to the socio political context within which a valuation is placed and the political goals it serves the relevance of this framework is demonstrated by applying it to three practical cases pollution damages water pricing and payments for ecosystem services

preference anomalies preference elicitation and the discovered preference hypothesis there is wide ranging evidence much of it deriving from economics experiments of anomalies in behaviour that challenge standard preference theories this paper explores the implications of these anomalies for preference elicitation methods because methods that are used to inform public policy such as contingent valuation are based on standard preference theories their validity may be called into question by the anomaly data however on a new interpretation these anomalies do not contradict standard theory but are errors in stated preference that can be expected to disappear as people become more experienced in relevant decision environments we explore the evidence for this interpretation and what implications follow for preference elicitation methodology

international technology transfer in services this study examines the nature of technology and the process of its transfer in five service industries from parent companies to foreign affiliates three principal research questions are posed what is the key technology in each industry what are the main methods for transferring this technology how and why do technology and transfer methods differ across firms industries and countries the empirical analysis shows that key technologies were generally knowledge of experience in the industry and methodology for producing the service transfer of the technology was mainly done through the training and transfer of experts and organizational forms were wholly owned subsidiaries and international partnerships more technology transfer occurred when firms were more international when affiliates were more recently established and when parent ownership was lower in the affiliate some evidence exists that more firm specific jointly produced technology leads to higher ownership percentage and greater transfer to affiliates

towards a fair constructive and consistent criticism of all valuation languages comment on kallis et al 2013 we provide critical notes to the paper by kallis et al 2013 on monetary valuation we evaluate the four criteria they propose for assessing valuation studies we argue that no clear distinction is made between monetary valuation and pricing instruments the selected criteria are more relevant to assessing policy than monetary valuation the examples provided are not representative of the diversity of valuation studies encountered in the literature moreover no clear examples are provided of where valuation and associated cost benefit analysis of environmental policy go wrong we plea for a more fair constructive and consistent criticism of all valuation languages and offer relevant issues for consideration

the limits of monetization in valuing the environment a reply to gsottbauer et al we welcome the attention of gsottbauer logar and van den bergh thereinafter glv to our contribution however their critique misrepresents what our article was trying to do so it merits a response our article offered a framework for assessing the conditions under which one may or may not engage with processes that value nature in money terms glv argue that first we confuse monetary valuation methods with pricing policies and that most of what we have to say may be relevant for the latter but not for the former second they argue that the assessment criteria we propose are either obvious or unconvincing third they contend that the examples we give to illustrate the applicability of our criteria are not representative and finally they suggest that our concern with whether a particular monetary valuation study or pricing policy contributes to enclosures and neo liberalism is ideological an

evaluation of biodiversity policy instruments what works and what doesn t w e review and confirm the claim that credible evaluations of common conservation instru ments continue to be rare the limited set of rigorous studies suggests that protected areas cause modest reductions in deforestation however the evidence base for payments for ecosystem services decentralization policies and other interventions is much weaker thus we renew our urgent call for more evaluations from many more biodiversity relevant locations specifically we call for a programme of research conservation evaluation 2 0 that seeks to measure how programme impacts vary by socio political and bio physical context to track economic and environmental impacts jointly to iden tify spatial spillover effects to untargeted areas and to use theories of change to characterize causal mechanisms that can guide the collection of data and the interpretation of results only then can we usefully contribute to the debate over how to protect biodiversity in developing countries

regulation and preemptive technology adoption two rival firms must decide if and when to adopt a new technology knowing how adoption costs decline over time and how profit flows vary with adoption patterns in many cases price and entry regulations beneficially slow technology adoption by making preemption strategies less attractive in some cases these regulations can so discourage a firm from preemption as to change the order in which firms adopt new technologies speeding one firm s adoption date and slowing the other s in the context of a particular scenario for cable and telephone companies adoption of new fiber optic technologies the case for lifting the cross ownership ban depends on the extent to which telephone companies are able to implement a superior technology reregulation of cable companies strengthens this case

choice certainty and consistency in repeated choice experiments the main objective of this study is to examine how repeated choice affects preference learning in stated preference experiments we test different hypotheses related to preference learning by analyzing response patterns and asking respondents in a choice experiment to report their experienced certainty when going through the choice tasks in a split sample test we show that follow up choice certainty questions are procedural invariant the self reported certainty results indicate that learning occurs but econometric testing procedures do not identify any significant impact of learning effects on parameter estimates or variance across choice tasks additional tests of choice consistency suggest that preferences in the choice experiment are stable and coherent

inward technology transfer and competitiveness the role of national innovation systems this paper examines the role of national innovation systems in the inward transfer of technology that has underpinned the transformation of japan and other east asian economies since 1945 the economies that have benefited most from inward technology transfer have national innovation systems that have strengthened their national absorptive capacity this capacity relies primarily on investments in scientific and technical training and on economic policies that enforce competition among domestic firms the particular channels for inward technology transfer the identity of any strategic industries targeted for public intervention and the overall level of a nation s trade restrictions are ail of secondary importance a central theme of global economic change during the postwar period has been the application in less developed countries of technologies developed within economically advanced regions this phenomenon underpinned the post 1945 transformation of japan and other east asian economies and influenced the reconstruction of western european economies after world war ii the application of externally developed technologies within latecomer economies is hardly unique to the postwar period however samuel slater s introduction of british textile manufacturing is but one example of inward technology transfer in the nineteenth century us economy and david 1992 traces the origins of patent monopolies to efforts by medieval european city states and nations to attract experts in industrial arts to practice their craft within these jurisdictions both international technology flows and government efforts to influence them for national competitive advantage thus have ample historical precedent several characteristics nevertheless distinguish the post 1945 era from earlier historical periods the influence of international technology transfer on national economic development has increased as the postwar development of such economies as taiwan and south korea has relied much less on natural resource endowments than nineteenth

faculty support for the objectives of university industry relations versus degree of r d cooperation the importance of regional absorptive capacity abstract the growing importance of regions in the analysis of innovation and the pressure on european universities to interact with their environment justify this article it argues that faculty support for the objectives of university industry relations uir does not vary across disciplines and does not respond to university encouragement in a region with low absorptive capacity these results are in contrast with those obtained in studies of technology leading countries like the usa furthermore incentives for uir may generate unpredicted dynamics while instruments to cooperate are not significant finally support for the objectives of uir should not be confused with the degree of r d cooperation the former is sensitive to university age while the latter is sensitive to gender discipline commitment to r d and university encouragement empirical evidence is obtained from a sample of faculty from the valencian community spain and analysed through a set of models for discrete choice

knowledge interactions between universities and industry in austria sectoral patterns and determinants the relationship between university and industry is a complex and heterogeneous phenomenon and an important topic of the recent debate on innovation systems this chapter explores the role of knowledge flows between universities and firms in the austrian national innovation system and provides valuable insights into several dimensions of knowledge flows that are not typically explored in research on this topic the patterns of interaction between 46 different fields of science and 49 economic sectors represent an important and interesting outcome of the analysis left censored tobit models are used to evaluate the effect of sector specific and science field specific characteristics upon the probability of knowledge interaction disaggregated by type of interaction

the ideology of efficiency searching for a theory of policy analysis the potential pareto improvement criterion and other measures of economic efficiency do not pass the test of consistency and coherence within economic theory nor do such measures accord with what public decision makers seek in policy advice from economists such efficiency measures are nonetheless durable components of the ideology of economics in general and benefit cost analysis in particular the objectivity of the policy scientist has been confused with the objectivity of the science while economic efficiency has no claim to objectivity the policy scientist can be an objective analyst of policy choices

innovation adoption and welfare under uncertainty the incentives of firms to adopt a new process need not coincide with maximum expected consumer surplus or social welfare if there is uncertainty before the process is adopted and if the only loss from failure is a fixed cost in some cases no firm will adopt an innovation likely to fail although expected welfare is maximized if one adopts in other cases both firms will adopt an innovation likely to succeed although expected welfare is maximized if one firm adopts this occurs because rivalry between firms leads them to adopt together when total expected profits are higher if one firm adopts copyright 1992 by blackwell publishing ltd

innovation and imitation in an asymmetrically regulated industry abstract we model a game of innovation and imitation between a regulated firm and an unregulated firm although regulation may slow the industry wide pace of innovation it does not necessarily do so in fact by weakening the regulated firm s incentive to imitate a rival s successful new technology regulation may make the rival s innovation profitable thereby accelerating innovation by extension giving the regulated firm stronger incentives may backfire by producing either excessive or insufficient innovation these negative outcomes are more likely the greater is the cost reducing potential offered by the new technology

paying for the hydrological services of mexico s forests analysis negotiations and results abstract mexico faces both high deforestation and severe water scarcity the payment for hydrological environmental services psah program was designed to complement other policy responses to the crisis at the interface of these problems through the psah the mexican federal government pays participating forest owners for the benefits of watershed protection and aquifer recharge in areas where commercial forestry is not currently competitive funding comes from fees charged to water users from which nearly us 18 million are earmarked for payments of environmental services applicants are selected according to several criteria that include indicators of the value of water scarcity in the region this paper describes the process of policy design of the psah the main actors involved in the program its operating rules and provides a preliminary evaluation one of the main findings is that many of the program s payments have been in areas with low deforestation risk selection criteria need to be modified to better target the areas where benefits to water users are highest and behavior modification has the least cost otherwise the program main gains will be distributive but without bringing a pareto improvement in overall welfare

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

r d rivalry with licensing or imitation the authors study the rivalry between two firms to develop an innovation in a dynamic setting that allows for post development dissemination of the innovation such as licensing or imitation this dissemination may cause the noninnovating firm to benefit from the discovery when this occurs conventional results in the economics of r d no longer need apply they find that industry leaders will tend to develop minor innovations but will develop major innovations only if imitation is difficult copyright 1987 by american economic association

interactive vs non interactive knowledge production by faculty members in this article we develop a model of individual choice to study the determinants of faculty members allocation of effort between interactive and noninteractive activities this model is tested by using censored and discrete choice econometric models to estimate optimum effort allocated to interactive activities and real interaction we conclude first that individual responds to nonmonetary rather than monetary incentives and to the difficulty of producing noninteractive rather than interactive knowledge second we detect the possible existence of rationing since optimum effort and real interaction depend on different variables

dynamic learning and context dependence in sequential attribute based stated preference valuation questions a hybrid stated preference model is presented that combines the referendum contingent valuation response format with an experimentally designed set of attributes a sequence of valuation questions is asked to a random sample in a mailout mail back format econometric analysis shows greater discrimination between alternatives in the final choice in the sequence and the vector of preference parameters shifts lead and lag choice sets have a structural influence on current choices and unobserved factors induce positive correlation across the responses these results indicate that people learn about their preferences for attributebased environmental goods by comparing attribute levels across choice sets

taking stock a comparative analysis of payments for environmental services programs in developed and developing countries abstract payments for environmental services pes are an innovative approach to conservation that has been applied increasingly often in both developed and developing countries to date however few efforts have been made to systematically compare pes experiences drawing on the wealth of case studies in this special issue we synthesize the information presented according to case characteristics with respect to design costs environmental effectiveness and other outcomes pes programs often differ substantially one from the other some of the differences reflect adaptation of the basic concept to very different ecological socioeconomic or institutional conditions others reflect poor design due either to mistakes or to the need to accommodate political pressures we find significant differences between user financed pes programs in which funding comes from the users of the es being provided and government financed programs in which funding comes from a third party the user financed programs in our sample were better targeted more closely tailored to local conditions and needs had better monitoring and a greater willingness to enforce conditionality and had far fewer confounding side objectives than government financed programs we finish by outlining some perspectives on how both user and government financed pes programs could be made more effective and cost efficient

performance of an agro forestry based payments for environmental services project in mozambique a household level analysis there has been a paucity of research on the impacts of small scale payments for environmental services pes projects in developing countries the aim of this paper is to evaluate the household level impacts of a small scale agro forestry based carbon sequestration project in rural mozambique in 2006 questionnaire based interviews were conducted quarterly of 290 randomly selected households in the buffer zone of the gorongosa national park in mozambique we used the propensity score matching technique to assess the pes project impacts on household cash income consumption expenditure forest resource use and crop yields we found that in contrast to nonparticipant households pes participant households earned more cash income incurred more consumption expenditure collected less forest products and harvested lower quantities of agriculture crops in addition we found through decomposition analysis that there was a differential in pes income both male headed and high income households were being favoured as project benefit recipients future pes projects should focus on a payment scheme that can better ensure the benefit to all the participant households and also pay extra attention on the benefits distribution to the vulnerable households

designing choice sets for stated preference methods the effects of complexity on choice consistency abstract we vary the complexity of choice sets used in stated preference methods to evaluate the impact on choice consistency we define five measures of complexity that capture either the amount of information or the correlational structure of information in a choice set using these measures as randomly assigned treatments in a large experiment we analyze the consistency of respondents choices using a heteroskedastic multinomial logit model we find that i all of our measures of choice set complexity affect choice consistency ii changes in the correlational structure of information have the largest impact on choice consistency and iii choice complexity significantly distorts welfare estimates our results confirm economists initial worry that moving from contingent valuation to conjoint methods will increase complexity induced choice inconsistency however our analysis also shows that these negative impacts may be mitigated if precautions are taken at the design and estimation stages of stated preference methods

science technology and regional economic development review and prospects abstract this paper reviews the literature on the location and regional effects of science and technology st these pools of mobile workers are most attracted to large urban areas in only some of these areas however does the spin off process result in the generation of new technology based firms the availability of local venture capital appears to be the principal influence on this variation government policy regarding science and technology has impacts on regions by contributing to the agglomeration of r d government policy also often fails to recognize that s t policy and industrial policy have regional effects that may be long term in nature and most detrimental to those regions whose economies are least competitive finally some priorities for future research on innovation in a regional setting are identified

the dynamics of innovation from national systems and mode 2 to a triple helix of university industry government relations abstract the triple helix of university industry government relations is compared with alternative models for explaining the current research system in its social contexts communications and negotiations between institutional partners generate an overlay that increasingly reorganizes the underlying arrangements the institutional layer can be considered as the retention mechanism of a developing system for example the national organization of the system of innovation has historically been important in determining competition reorganizations across industrial sectors and nation states however are induced by new technologies biotechnology ict the consequent transformations can be analyzed in terms of neo evolutionary mechanisms university research may function increasingly as a locus in the laboratory of such knowledge intensive network transitions

the demand for climate protection empirical evidence from germany abstract an experiment designed to find the real demand for climate protection was conducted among a sample of the residential population in mannheim germany participants were offered the opportunity to contribute to climate protection by purchasing european union allowances which were then withdrawn from the european emissions trading scheme our experiment showed a median willingness to pay wtp of zero and a mean wtp of approximately 12 t co 2

technology transfer and public policy a review of research and theory abstract my purpose is to review synthesize and criticize the voluminous multidisciplinary literature on technology transfer to reduce the literature to manageable proportions i focus chiefly not exclusively on recent literature on domestic technology transfer from universities and government laboratories i begin by examining a set of fundamental conceptual issues especially the ways in which the analytical ambiguities surrounding technology transfer concepts affect research and theory my literature review follows and i emphasize technology transfer s impact and effectiveness i employ a contingent effectiveness model of technology transfer to organize the literature as the model s name implies it assumes that technology effectiveness can take a variety of forms in addition to examining the more traditional effectiveness criteria those rooted in market impacts the model considers a number of alternative effectiveness criteria including political effectiveness capacity building

coherent arbitrariness stable demand curves without stable preferences economic theories of valuation generally assume that prices of commodities and assets are derived from underlying fundamental values for example in finance theory asset prices are believed to reflect the market estimate of the discounted present value of the asset s payoff stream in labor theory the supply of labor is established by the tradeoff between the desire for consumption and the displeasure of work finally and most importantly for this chapter consumer microeconomics assumes that the demand curves for consumer products chocolates cds movies vacations drugs and so forth can be ultimately traced to the valuation of pleasures that consumers anticipate receiving from these products because it is difficult as a rule to measure fundamental values directly empirical tests of economic theory typically examine whether the effects of changes in circumstances on valuations are consistent with theoretical prediction for example whether labor supply responds appropriately to a change in the wage rate whether compensated demand curves for commodities are downward sloping or whether stock prices respond in the predicted way to share repurchases however such comparative static relationships are a necessary but not sufficient condition for fundamental valuation e g summers 1986 becker 1962 was perhaps the first to make this point explicitly when he observed that consumers choosing commodity bundles randomly from their budget set would nevertheless produce downward sloping demand curves

diversification incentives under price based and cost based regulation this article considers two schemes of regulationforfirms that serve both monopoly markets and markets subjected to substantial competition the first form cost based regulation combines elements of rate of return regulation on monopoly markets with filly distributed cost pricing much like the form of regulation currently in place in the domestic telephone industry the secondform price based regulation would establish rate caps on noncompetitive services and allow the firm to enter into competitive markets and charge whatever prices it might like in those markets models of both forms of regulation are developed and analyzed with respect to incentives for cost misreporting choice of technology cost reducing innovation choices of prices and output levels and diversification into competitive markets

adoption of cost saving innovations by a regulated firm regulatory lag is generally credited with providing monetary incentives for the adoption of cost saving technological changes by regulated firms because regulators can not instantaneously adjust price ceilings in response to cost changes these incentives are inherent to the process of price regulation in a dynamic world a firm which decreases production costs through technological innovation will enjoy excess profits until the regulators lower price to a level consistent with the new conditions the longer the delay before regulatory response to a decrease in cost the greater are the profits which can be derived from a cost reduction and therefore the greater is the incentive for adoption of technological change 2 the passive nature of this incentive mechanism is an important characteristic although regulatory agencies typically have authority to force price decreases upon firms which do not take advantage of potential cost savings this power is limited by the difficulty of proving that a firm is laggard rather than the victim of unfortunate circumstances thus the regulated firm which foregoes potential profit from adopting a costsaving innovation today may generally reap that profit at some convenient time tomorrow indeed it is the main contention of this paper that in many circumstances a regulated monopolist can maximize the present value of profits only by delaying adoption of an innovation that is rather than completely adopting a cost saving innovation when it becomes available a profit maximizing regulated firm will choose to adopt the innovation only gradually through time the profitability of such delaying procedure may be illustrated by a simple example consider a situation in which the price of a firm s product is fixed by a regulatory authority but periodically adjusted according to the following cost plus markup scheme at each review price for the following period is set equal to average cost of the previous period plus an allowed markup that is price in period i 1 is set equal to m times average cost in period i m 1 this situation is illustrated in figure 1 a firm is initially producing output qo at cost co qo with price set by the regulators at mco qo qo suppose a cost saving innovation is discovered which if employed would decrease average production cost to c1 q q if the firm were to adopt this innovation immediately it would earn a profit equal to the area of the rectangle abcd in figure ia at the next regulatory review price would be lowered to the level m times the new average cost i e to p1 and profit would fall to that amount represented by the area aefg this amount of profit would be earned each period thereafter however suppose that the firm were to adopt this innovation in two steps rather than completely adopting the innovation when it first becomes available this option is sketched in figure lb in the initial period the firm adopts the innovation throughout approximately half its operations thereby lowering average cost only to oh in the next period the firm completes the adoption process lowering average cost to the final level oa although this procedure would yield profit equal only to hicd in the initial period it would result in a price in the next period equal to p1 i e equal to m times oh since average cost in that period would fall to oa profit would equal ajkl in the next period price would be at the new equilibrium level og and profit would equal aefg this amount of profit would be earned each period thereafter given the demand and cost functions illustrated in figure 1 the second alternative assistant professor of economics vanderbilt university see william baumol and alfred kahn ch 2 2see elizabeth bailey
