the structure of licensing contracts industrial organization theory has explored several issues related to licensing but empirical analyses are extremely rare we amass a new and detailed dataset on licensing contracts and use it to present some simple facts concerning licensing behavior our analysis reveals robust cross industries differences in several contractual features such as exclusivity cross licensing ex ante versus ex post technology transfers and licensing to related versus unrelated parties we offer an interpretation of these facts based on cross industry variation in the strength of intellectual property rights

the impact of the timing of patents on innovation performance abstract in the context of industry standard setting firms face the strategic decision of whether to move faster than competitors or wait for more information that reduces uncertainty these decisions are even more challenging if there are multiple standards and if there are benefits to belonging to more than one standard this paper examines the effect of the timing of patents on a firm s innovation performance the strategic logic of real options posits that patent timing is determined by the tension between the value of preemption and the value of waiting we analyze 680 dvd disc patents in dvd patent pools to test the effect of the timing of patents on innovation performance consistent with real options logic under high uncertainty the later the timing of the patent the higher the innovation performance while under low uncertainty there is an early mover advantage

size r d productivity and decision styles we extend the size innovation debate by incorporating decision making style as a relevant factor in the innovation process we propose that the size of firms affects the scale and quality of product innovation through the adoption of different decision making styles using the literature on cognition we conceptualize decision making style as the degree to which firms rely on analytical information for decision making during the r d process using longitudinal data of spanish firms we show that as firms increase in size they rely more extensively on analytical decision tools for the innovation activity additionally we show that the size of firms is negatively related to product innovation productivity in terms of scale and positively related to the quality and that these relationships are mediated by firms reliance on analytical decision making style we discuss theoretical and managerial implications for innovation research and practice

does energy poverty really exist in china from the perspective of residential electricity consumption abstract china is undergoing a market oriented reform in energy and the residential sector will be involved in the near future the analysis of energy poverty is crucial in breaking the illusion of the dilemma between enhancing energy efficiency and controlling poverty based on chinese residential energy consumption survey we firstly estimated the energy poverty in china by the 10 indicator and lihc indicators and then proposed a minimum end use method to classify the energy poor households into lifeline and consumption energy poverty results show that energy poverty exists in china at the proportion of 18 9 and 46 of the energy poor houses are in short of modern energy consumption and are sensitive to tariffs with a level of electricity consumption lower than the basic demand the energy poverty rate is highest in central china while the lifeline energy poor are relatively concentrated in the western region in terms of public policy we suggest focusing on heterogeneity by considering different groups of households when implementing energy efficiency measures and targeting more on the consumption energy poor in poverty alleviation we also suggest paying particular attention to targeting households with low income by supporting practices such as coupons for energy consumption and appliance purchasing

competition and substitutability in the swedish pharmaceuticals market substitution possibilities between brand name pharmaceuticals are analysed the analysis is based on data from three different markets the prescription drug market for beta blocking agents the over the counter market for purgatives and the hospital market for two pharmaceutical treatments for gastric ulcers the results indicate that there exist some substitution possibilities among the brand name drugs included in the study

global markets for technology evidence from patent transactions abstract the paper analyses the recent evolution of international markets for technology by examining changes in ownership of us granted patents we study the effects of the geographical origin of patents proxied by their first priority country on the probability of patents being traded on the timing of the transaction and on the probability of observing a cross border transaction while controlling for the characteristics of the patents the time and sector specificities the analyses are based on a comprehensive dataset that covers all the patents granted by the uspto over the 2002 2012 period the data from the us patent reassignment database have been cleaned and processed and a subset of 95 542 granted patents that have been traded has been identified we obtain evidence from survival models that there has been an increase in the rate of patent transactions in recent years the obtained results indicate that patents with a first non us original applicant have less probability of being traded and show a longer time to transaction than us first priority patents we also find that more science based patents which are usually characterized by a higher technological uncertainty are more likely to be traded but are much less likely to be involved in cross border deals the results are discussed in light of the impact of asymmetric information and search costs on international patent transactions

international technology licensing monopoly rents transaction costs and exclusive rights as firms increasingly use licensing to exploit knowledge based assets in global technology markets appropriate structuring of these agreements has become an important line of research inquiry one area that has received less attention is the nature of rights granted in inter firm licensing relationships although it is an important clause that has implications for profit generation from licensing of proprietary assets conceptualizing licensing rights in terms of number of licenses granted and exclusivity rights given to a licensee in a foreign market this paper examines the determinants of these rights based on monopoly rents and transaction costs associated with different types of licensing contracts hypotheses are empirically tested through two studies one based on large us manufacturing firms and the other on a cross national sample of medium sized firms actively involved in international technology licensing results from both studies show a greater propensity to use non exclusive multiple licensing when the licensed technology has greater potential to produce differentiated products or when there is greater threat of substitutive technologies entering the market on the other hand innovative technologies and a higher degree of asset specific investments required of the licensee for the technology are related to the use of single exclusive licensing agreements

patient or physician oriented marketing what drives primary demand for prescription drugs abstract the authors analyze primary demand effects of marketing efforts directed at the physician detailing and professional journal advertising versus marketing efforts directed at the patient direct to consumer advertising the analysis covers 86 categories or approximately 85 of the u s pharmaceutical market during the 2001 2005 period primary demand effects are rather small in contrast with the estimated sales effects for individual brands by using a new brand level method to estimate primary demand effects with aggregate data the authors show that the small effects are due to intense competitive interactions during the observation period but not necessarily to low primary demand responsiveness in contrast with previous studies the authors also find that detailing is more effective in driving primary demand than direct to consumer advertising a category sales model cannot provide such insights in addition a category sales model likely produces biased predictions about period by perio

determinants of international activity evidence from the chemical processing industry abstract this paper empirically investigates two important determinants of international activity through wholly owned operations joint ventures and technology licensing namely country risk and intellectual property rights iprs protection using a comprehensive database on investments in chemical plants during the period 1981 1996 we show that higher levels of country risk are associated with less activity into recipient economies the analysis also suggests that international activity with smaller resource commitment tends to be preferred in countries with higher levels of risk and that multinational investment is more responsive to changes in risk conditions than indigenous investment after controlling for several country characteristics we do not find iprs protection playing a significant role in fostering international activity or conditioning its mode

estimating the effects of global patent protection in pharmaceuticals a case study of quinolones in india under the trips agreement wto members are required to enforce product patents for pharmaceuticals the debate about the merits of this requirement has been extremely contentious many low income economies claim that patent protection for pharmaceuticals will result in substantially higher prices for medicines with adverse consequences for the health and well being of their citizens on the other hand research based global pharmaceutical companies argue that prices are unlikely to rise significantly because most patented products have therapeutic substitutes in this paper we empirically investigate the basis of these claims central to the ongoing debate is the structure of demand for pharmaceuticals in poor economies where because health insurance coverage is so rare almost all medical expense are met out of pocket using a detailed product level data set from india we estimate key price and expenditure elasticities and supply side parameters for the fluoroquinolones sub segment of the systemic anti bacterials i e antibiotics segment of the indian pharmaceuticals market we then use these estimates to carry out counterfactual simulations of what prices profits and consumer welfare would have been had the fluoroquinolone molecules we study been under patent in india as they were in the u s at the time our results suggest that concerns about the potential adverse welfare effects of trips may have some basis we estimate that in the absence of any price regulation or compulsory licensing the total annual welfare losses to the indian economy from the withdrawal of the four domestic product groups in the fluoroquinolone sub segment would be on the order of u s 450 million or about 73 of the sales of the entire systemic anti bacterials segment in 2000 of this amount foregone profits of domestic producers constitute roughly 50 million or 11 the overwhelming portion of the total welfare loss therefore derives from the loss of consumer welfare in contrast the profit gains to foreign producers in the absence of any price regulation are estimated to be only around 53 million per year

cross national price differences for pharmaceuticals how large and why bilateral drug price and quantity indexes based on comprehensive data for seven countries us canada france germany italy japan and the uk refute the conventional wisdom that us drug prices are much higher than elsewhere for laspeyres us weighted indexes previous drug price comparisons are biased by unrepresentative samples and unweighted indexes quasi hedonic regression shows that cross national price differences reflect differences in product characteristics and in their implicit prices which reflect the regulatory regime strict price regulation systematically lowers prices for older molecules and globally diffused molecules generic competition lowers prices in less regulated regimes which also have more price elastic demand

measuring fuel poverty in france which households are the most fuel vulnerable fuel poverty is a growing concern in france following the hike in energy prices that started in 2004 the problem of energy affordability for low income households entered the political debate with the grenelle de l environnement in 2007 according to the standard uk definition 10 ratio 3 8 million households were subject to fuel poverty in france in 2006 we question the way fuel poverty is currently measured and compare the impact of alternative measurement approaches on the extent and composition of fuel poverty in france then we identify and characterize vulnerable households that are not ordinarily poor but can be pushed into poverty because of their fuel bills a logit a clog log and a mixed effect logit model are used to analyze which factors influence the probability of vulnerable households to fall into poverty the study indicates that the proportion of fuel poor people and their characteristics differ significantly depending on the fuel poverty measure chosen the econometric results show that the probability of falling into poverty is higher for those who are retired living alone rent their home use an individual boiler for heating cook with butane or propane and have poor roof insulation current french fuel poverty reduction policies appear to be inappropriate given our conclusions

consumption externalities and diffusion in pharmaceutical markets antiulcer drugs we examine the role of consumption externalities in the demand for pharmaceuticals at both the brand level and over a therapeutic class of drugs externalities emerge when use of a drug by others affects its value and or conveys information about efficacy and safety to patients and physicians this can affect the rate of market diffusion for a new entrant and can lead to dominance of one drug despite the availability of close substitutes we use data for h2 antagonist antiulcer drugs to estimate a dynamic demand model and quantify these effects the model has three components an hedonic price equation that measures how the aggregate usage of a drug as well as conventional attributes affect brand valuation equations relating equilibrium market shares to quality adjusted prices and marketing levels and diffusion equations describing the dynamic adjustment process we find that consumption externalities influence both valuations and rates of diffusion and that they operate at the brand and not the therapeutic class level

competition in off patent drug markets issues regulation and evidence in recent years health insurers have placed a great deal of emphasis on the ability of generic medicines to deliver significant savings to overstretched health care budgets due to their lower cost and potential for a more efficient resource allocation in this paper we study market developments after patent expiry whether health insurance captures the financial benefits from cheaper generics and whether regulation and product differentiation among others have any power in explaining originator and generic price movements generic entry and diffusion we find that health insurance does not capitalize fully or fast enough on the cost advantage of generic medicines either because generic policies do not encourage their fast uptake or because generic drug prices are high and frequently tied directly or indirectly to originator drug prices we also find that reference pricing a particular form of reimbursement regulation encourages generic entry and reduces generic prices but only marginally finally in generic markets characterized by homogeneous products we find evidence of product differentiation which is impacting prices upwards rather than downwards if health insurance is to benefit fully from generic medicines it ought to encourage faster uptake and price competition and discourage price fixing regulation that ties generic prices to those of originator brands panos kanavos joan costa font and elizabeth seeley

energy poverty in china an index based comprehensive evaluation abstract energy poverty has got increasing attention during the latest three decades measuring energy poverty is the premise of policy making to alleviate energy poverty there is no unified energy poverty measurement that has been widely accepted this paper reviews the commonly used energy poverty measurements through classifying them into three categories energy service availability energy service quality and satisfaction of energy demand for human s survival and development this paper also analyzes the suitability of the commonly used energy poverty measurement for china from the prospective of data availability and index applicability furthermore we construct a new energy poverty comprehensive evaluation index in this study and the index is illustrated to evaluate regional energy poverty in china the evaluation results indicate that china s energy poverty showed an alleviating trend from 2000 to 2011 and during this period china s energy service availability improved slightly energy consumption cleanliness showed no significant change energy management completeness decreased with fluctuations and household energy affordability and energy efficiency improved continually in addition china s regions show different characteristics of energy poverty for example middle reaches of yangtze river region showed the worst energy availability and eastern coastal region showed the worst energy management completeness several policy implications for energy poverty alleviation are also proposed in this study including for instance increasing investment on energy infrastructure and spreading energy management organization in rural area decreasing relative cost on household commercial energy consumption and encourage the utilization of modern clean and efficient household energy consumption equipment

pharmaceutical price controls and entry strategies abstract this paper finds that the use of price controls has a statistically and quantitatively important effect on the extent and timing of the launch of new drugs firms headquartered in countries that regulate price reach fewer markets than those in countries without price controls companies avoid price controlled markets and are less likely to introduce products in additional markets after entering a price controlled country launches into low price european countries are further delayed following legalization of parallel imports the results suggest that price regulation in one country affects entry into other countries and may affect the strategies of domestic firms

measuring energy poverty in japan 2004 2013 abstract this paper first examines energy or fuel poverty in japan from 2004 to 2013 especially around the time of the 2011 great east japan earthquake geje to analyze the issue the paper employs various poverty and vulnerability measures with the assistance of our unique dataset the results indicate the aggravation of energy poverty among lower income and vulnerable households during the past decade resulting from both the escalation of energy prices and lowering of income the analysis also employs a new decomposition technique and identifies the explanatory factors associated with the increase in energy poverty these results suggest there were major changes in the forces driving the increase in energy poverty before and after the geje after 2011 income alleviates energy poverty in japan with energy prices becoming the main driving factor

comprehensive energy poverty index measuring energy poverty and identifying micro level solutions in south and southeast asia abstract the absence of adequate modern sources of energy impedes the presence of decent living conditions this very lack of modern sources of energy is energy poverty lack of availability accessibility and affordability are the main reasons behind this problem in the literature all three aspects were not covered together in this paper we have developed a composite index of energy poverty to measure the magnitude of energy poverty in the asean region and india where we capture all three elements the measure revealed the degree of problem in each country with cambodia being the most energy poor amongst the countries in the study and thailand being the least energy poor to dig deeper into the problem at the micro level and to deliberate the policy implications we developed detailed village level case studies and analysed region specific energy poverty we thus identify the key root causes and propose effective solutions to eradicate the prevailing problem in these regions

patents licensing and market structure in the chemical industry abstract the strategies of rent appropriation and industry structure are inter dependent how firms use patents depends upon industry structure and in turn affects industry structure in the 19th century market leaders in the chemical industry combined patents and secrecy to deter entry within cartels patents were used to stabilize cartels and organize technology licensing the role of patents changed in the less concentrated post world war ii markets in bulk organic chemicals and petrochemicals chemical producers use licensing as an important means of generating revenue from process innovations the increased importance of technology licensing is closely related to the emergence of a class of specialized process design and engineering firms that have played an important role in the development and diffusion of process innovations

choosing the competition and patent licensing this article examines licensing as a means of choosing the competitors which a patentee monopolist will face in the period after the patent expires the queue of entrants consists of two firms which differ in their relative strengths as competitors for example by size or level of marginal cost by structuring the industry to be composed of weak competitors the incumbent is able to prolong its dominant position in the industry after the patent expires examples are presented in which the evidence suggests that choosing the competition was an important motivation of the licensor s behavior

mergers with differentiated products the case of the ready to eat cereal industry traditional merger analysis is difficult to implement when evaluating mergers in industries with differentiated products i discuss an alternative which consists of demand estimation and the use of a model of postmerger conduct to simulate the competitive effects of a merger i estimate a brand level demand system for ready to eat cereal using supermarket scanner data and use the estimates to 1 recover marginal costs 2 simulate postmerger price equilibria and 3 compute welfare effects under a variety of assumptions the methodology is applied to five mergers two of which occurred and for which i compare predicted to actual outcomes

licensee technological potential and exclusive rights in international licensing a multilevel model granting of exclusive rights is an important consideration for firms using licensing as a mode of entry into foreign markets as exclusive contracts reduce licensors flexibility in a given market during the term of the agreement by granting exclusivity to a licensee with greater technological potential the exchange partners can increase the potential transactional value of the licensing agreement at the same time a licensee with strong technological potential will increase the threat of transactional hazards due to underinvestment and rent appropriation in this paper we develop and empirically test a model that evaluates the balancing of transactional value and transaction costs in exclusive licensing in particular we identify the conditions under which exclusive contracts are likely to be granted to foreign licensees with strong technological potential empirical results from a multilevel model based on 375 international licensing agreements of us firms in high technology industries during 1995 2008 show that licensees with a stronger technological potential are more likely to be granted exclusive rights in countries with strong intellectual property rights protection and in industries with a high rate of technological change but are less likely to be granted exclusive rights when there is a high degree of overlap between licensor and licensee products

quantifying the severity of fuel poverty its relationship with poor housing and reasons for non investment in energy saving measures in ireland fuel poverty has generally been calculated by quantifying the number of households spending in excess of 10 of income on home heating this definition has a number of significant practical and scientific limitations this paper employs self reported data to calculate the severity of fuel poverty in ireland to identify chronic fuel poor households from occasional sufferers it also assesses domestic energy efficiency levels ireland is a useful case study as it demonstrates the highest variations in seasonal mortality and morbidity in northern europe both of which are associated with fuel poverty ireland is also experiencing extreme difficulties meeting its environmental emissions targets in light of recent spectacular economic growth reducing fuel poverty would lower energy related emissions assisting policy makers achieve these challenging targets furthermore little empirical research has been undertaken on fuel poverty in ireland this paper identifies key social groups at risk by conducting detailed socio economic and socio demographic analyses the relationship between fuel poverty and adverse housing conditions damp condensation is also examined moreover the reasons behind householders not investing in energy saving measures are reported the results show that ireland suffers from similar levels of fuel poverty as the uk with low income households suffering the greatest the key policy implications are outlined

measuring energy poverty in greece a comprehensive research in the field of energy poverty is undertaken in this paper in an attempt to highlight the great vulnerability of greek households on energy poverty in the middle of a severe economic crisis till now greek energy policy has been considered insufficient to tackle energy poverty issues as focusing mainly on short term rather than permanent solutions a primary survey has been conducted recording objective data of energy expenses as well as subjective perceptions about housing conditions the findings showed that under the objective expenditure based method 58 of greek households are energy poor among households under the poverty threshold the energy poverty rate exceeds 90 existing and new subjective indicators shed light on other aspects of energy poverty such as the level of thermal comfort at home damp problems detected restriction of other essential needs in order to manage energy payments etc some interesting conclusions are also drawn by exploring the relationship between various indicators it appears that households considered energy poor are not identical when examined by objective and subjective indicators however different indicators complement each other by capturing different aspects of the problem and provide a broader overview of the issue

characteristics of demand for pharmaceutical products an examination of four cephalosporins we model demand for four cephalosporins and compute own and cross price elasticities between branded and generic versions of the four drugs we model demand as a multistage budgeting problem and we argue that such a model is appropriate to the multistage nature of the purchase of pharmaceutical products in particular the prescribing and dispensing stages we find quite high elasticities between generic substitutes and also significant elasticities between some therapeutic substitutes

closed or open innovation problem solving and the governance choice scholars have recently highlighted the promise of open innovation in this paper we treat open innovation in it s different forms and manifestations as well as internal or closed innovation as unique governance forms with different benefits and costs we discuss how each governance form whether open or closed is composed of a set of instruments that access a different types of communication channels for knowledge sharing b different types of incentives and c different types of property rights for appropriating value from innovation we focus on the innovation problem as the central unit of analysis arguing for a match between problem types and governance forms which vary from open to closed and which support alternative forms of solution search in all the goal of this paper is to provide a comparative framework for managing innovation where we delineate and discuss four categories of open innovation governance forms markets partnerships contests and tournaments and user or community innovation and compare them with each other and with two internal or closed forms of innovation governance authority and consensus based hierarchy

energy poverty in rural bangladesh energy poverty is a well established concept among energy and development specialists international development organizations frequently cite energy poverty alleviation as a necessary condition to reduce income poverty several approaches used to measure energy poverty over the past 20 years have defined the energy poverty line as the minimum quantity of physical energy needed to perform such basic tasks as cooking and lighting this paper uses a demand based approach to define the energy poverty line as the threshold point at which energy consumption begins to rise with increases in household income at or below this threshold point households consume a bare minimum level of energy and should be considered energy poor this approach was applied using cross sectional data from a comprehensive 2004 household survey representative of rural bangladesh the findings suggest that some 58 percent of rural households in bangladesh are energy poor versus 45 percent that are income poor the findings also suggest that policies to support rural electrification and greater use of improved biomass stoves might play a significant role in reducing energy poverty

from free entry to patent protection welfare implications for the indian pharmaceutical industry abstract there has been fierce debate over the imposition of stronger intellectual property rights laws for pharmaceutical products in developing countries this paper uses data from the indian pharmaceutical industry to develop a structural model of demand supply and entry the estimation yields demand and supply parameters that indicate significant heterogeneity among firms both within and across different therapeutic segments the estimated parameters are used to simulate patent enforcement and price deregulation for 43 drugs which predicts large losses for consumers and relatively small gains in profits for the global patent holders

deterrence by market sharing a strategic incentive for licensing the potential of an incumbent firm to retain its dominant position in a market is a focal point of the modem theory of industrial organization a recent literature examines this issue for markets in which challengers threaten an incumbent s position by engaging in research for a new technology richard gilbert and david newbery 1982 show that an incumbent firm with a firstmover advantage will preempt potential entrants by inventing a new technology slightly earlier than would its rivals in a stochastic r d therefore its introduction does not alter the decision to research when the pre innovation market is characterized by an incumbent and potential entrants stephen salant 1984 shows that licensing ex post to innovation can alter the research decision as anticipation of the returns from future licensing encourages research by the entrant as a counterpoint to the salant result i find that licensing ex ante to research may discourage further research by the entrant indeed this strategic incentive for licensing may be so strong as to persuade the incumbent as well as the entrant to terminate research activity to isolate this incentive for licensing from the one discussed by salant a simple model is constructed in which licensing of future technologies is not desirable anecdotal evidence suggests that the strategic incentive does lead innovators in some markets to license their technologies examples of this information sharing are prevalent in markets where technological change is rapid in the 1940 s standard oil of new jersey discovered a process for synthetic rubber it traded patent rights on this process for a synthetic oil production process discovered by farben a german rubber company in both the synthetic oil and synthetic rubber markets rival companies were department of economics scarsborough college university of toronto toronto ontario canada m5s lal i thank jon cohen and ron saunders for discussions that inspired this paper i am also grateful to yehuda kotowitz andy mclennan jennifer reinganum ralph winter myma wooders two anonymous referees and seminar participants at the university of toronto for helpful comments on earlier drafts

regulation and pricing of pharmaceuticals reference pricing or price cap regulation we study the relationship between regulatory regimes and pharmaceutical firms pricing strategies using a unique policy experiment from norway which in 2003 introduced a reference price rp system called index pricing for a sub sample of off patent pharmaceuticals replacing the existing price cap pc regulation we estimate the effect of the reform using a product level panel dataset covering the drugs exposed to rp and a large number of drugs still under pc regulation in the time before and after the policy change our results show that rp significantly reduced both brand name and generic prices within the reference group with the effect being stronger for brand names we also identify a negative cross price effect on therapeutic substitutes not included in the rp system in terms of policy implications the results suggest that rp is more effective than pc regulation in lowering drug prices while the cross price effect raises a concern about patent protection

technology transfer under asymmetric information licensing contracts for newly patented innovations are observed to vary along several dimensions including the form and size of the payment to the inventor fixedfee versus some output based royalty the degree of exclusivity and the division of rents in this article we show that theform of the contract can be explained by two problems in technology exchange the superiority of a licensor s precontractual information about the economic value of the innovation and thefact that sharing this information with the licensee mayfacilitate imitation we show that a licensor signals her technology type with an output based payment or royalty and may leave some of the rents with the licensee conditions under which exclusive license contracts linear and nonlinear and nonexclusive linear contracts are used to transfer technology are identified

licensing radical product innovations to speed up the diffusion abstract we present a differential game to study how companies can simultaneously license their innovations to other firms when launching a new product the licensee may cannibalize licensor s sales albeit this can be compensated by gains from royalties nonetheless patent royalties are generally so low that licensing is not an attractive strategy in this paper we consider the role of licensing to speed up the product diffusion word of mouth by licensee s customers and licensee s advertising indirectly push forward sales of the licensing company accelerating new product diffusion we find evidence that licensing can be a potentially profitable strategy however we also find that a weak intellectual property right ipr protection can easily diminish the financial attractiveness of licensing

assessing the extent and intensity of energy poverty using multidimensional energy poverty index empirical evidence from households in india abstract in this paper we have made a comprehensive assessment of the extent and various socio economic implications of energy poverty in india amartya sens s capability approach to development underpins the analysis of household level data taken from the india human development survey ii ihds ii 2011 12 using the multidimensional energy poverty index mepi the overall results show that energy poverty is widespread in india and the existence of energy poverty also coincides with the other forms of deprivations such as income poverty and social backwardness for example dalits lower caste and adivasis tribal are found to be extremely energy poor compared to the other social groups in india the results also reveal that it is the responsibility of women to manage the domestic chores such as collection of firewood and making of dung cake in traditional indian households inefficient use of such biomass fuels is found to cause health hazards

energy poverty an overview abstract in the coming decades the energy sector will have to face three major transformations concerned with climate change security of supply and energy poverty the first two have been extensively analysed but less attention has been paid to the third even though it has a great influence on the lives of millions of people this paper presents an overview on energy poverty different ways of measuring it and its implications according to the who indoor pollution causes an estimated 1 3 million deaths per annum in low income countries associated with the use of biomass in inadequate cookstoves although energy poverty cannot be delinked from the broader more complex problem of poverty in general access to energy infrastructures would avoid its most serious consequences and would help to encourage autonomous development according to the iea the cost of providing universal access to energy by 2030 would require annual investment of 35 billion i e much less than the amount provided annually in subsidies to fossil fuels finally the paper argues that energy and energy poverty need to be incorporated into the design of development strategies

subjective versus objective energy burden a look at drivers of different metrics and regional variation of energy poor populations abstract energy poverty is typically assessed using the energy expenditure to income ratio as a metric this metric fails to account though for residents demographics and regional variation in energy consumption in the united states policymakers dealing with energy poverty have faced challenges estimating the needs for energy assistance programs this study seeks to explore regional variations in energy poverty using texas as the region of study this work also explores differences in the populations captured via objective and subjective metrics i e those who are unable to pay their bill and those who state they struggle to do so drawing on survey data this work uses statistical analyses to 1 assess the regional variation of energy poverty defined as a ratio of household income spent on electricity bills 2 determine if there is an association between objective and subjective metrics of energy poverty and 3 identify statistical drivers of objective and subjective energy poverty metrics of respondents 51 of objectively energy burdened individuals indicated they struggled to pay electricity bills and 53 faced great stress due to the electricity bill if policymakers can use metrics that are more accurate in capturing populations facing energy poverty more effective energy poverty policies might be formulated

making the connection the relationship between fuel poverty electricity disconnection and prepayment metering abstract fuel poverty or inability to afford adequate heating for a reasonable outlay of expenditure is a significant and under researched problem in new zealand the connection between fuel poverty and electricity disconnection or self disconnection is analysed for four cities using prepayment metering to pay for electricity a price comparison analysis on a government sponsored website showed that prepayment metering was more expensive than other payment options this website analysis was supplemented by qualitative data from older people with chronic respiratory disease expressing their views about electricity disconnection and prepayment metering we show that prepayment metering for electricity is more expensive than other payment methods in new zealand and that older people s insights provide valuable context to these issues under the present payment schedule the use of prepayment metering to pay for electricity is not a suitable policy instrument to address fuel poverty which remains problematic the deregulated electricity market continues to lead to increases in the real price of residential electricity and in the number of people in fuel poverty we offer policy suggestions for reducing fuel poverty in new zealand

cut throat fringe competition in an emerging country market tax evasion or the absence of market power brazil s established soft drink firms recently lost ground to multiple low price entrants with small scale operations and minimal advertising while incumbents attributed such undercutting to entrants lower costs from non compliance with the law generics counterargued that incumbents high prices stemmed from unilateral market power rather than cost heterogeneity by estimating a structural model i can single handedly explain established brands high prices through low equilibrium price elasticities of demand tax evasion in the fringe while plausible appears to be offset by higher procurement costs or less efficient scale more generally a competitive informal sector can alleviate the allocative distortions in certain concentrated industries

reference pricing competition and pharmaceutical expenditures theory and evidence from a natural experiment abstract we study the impact of regulation on competition between brand names and generics and pharmaceutical expenditures using a unique policy experiment in norway where reference pricing rp replaced price cap regulation in 2003 for a sub sample of off patent products first we construct a vertical differentiation model to analyze the impact of regulation on prices and market shares of brand names and generics then we exploit a detailed panel data set at product level covering several off patent molecules before and after the policy reform off patent drugs not subject to rp serve as our control group we find that rp significantly reduces both brand name and generic prices and results in significantly lower brand name market shares finally we show that rp has a strong negative effect on average molecule prices suggesting significant cost savings and that patients copayments decrease despite the extra surcharges under rp

generic entry price competition and market segmentation in the prescription drug market abstract this paper studies the effects of generic entry on post patent price competition for 18 prescription drugs recently exposed to competition an independent validating test of the generic competition paradox is conducted using a newly created data set each generic entrant is associated with an average 1 increase in the branded price the one way error component model accounts for intermolecular competition market segmentation and endogeneity of entry and finds branded prices increasing by 2 alternative definitions of entry suggest that price competition is confined to the generic market the unique payer type feature of the data offers empirical evidence supporting market segmentation

divisionalization franchising and divestiture incentives in oligopoly a two stage game is used to model firms strategic incentives to divide production among autonomous competing units through divisionalization franchising or divestiture firms simultaneously choose their number of competing units which then engage in cournot competition while it is costly to form autonomous units each firm does so in equilibrium thus reducing firm profits and increasing social welfare relative to the case where firms cannot form competing units with linear demand and costs duopolists choose the socially optimal number of competing units oligopolies with larger numbers of firms choose too many the case of nonlinear demand is also examined copyright 1996 by american economic association

impact of direct to consumer advertising on pharmaceutical prices and demand author affiliation dhaval dave ddave bentley eduhenry saffer hsaffer gc cuny edu acknowledgment this research was supported by a grant from the agency for healthcare research and quality to the national bureau of economic research the authors are grateful to gregory colman robert feinberg michael grossman dominic hodgkin rick smith and two anonymous reviewers for valuable comments li ma and zhen ma provided excellent research assistance 1 introductionbetween 1995 and 2007 expenditures on prescription drugs increased by 274 raising the drug related share of total health care spending from 6 to over 10 and making it one of the fastest growing components of health care costs 1 the growth in prescription drug expenditures has coincided with the growth in pharmaceutical promotion which increased from 11 4 billion in 1996 to 29 9 billion in 2005 donohue cevasco and rosenthal 2007 promotion of prescription drugs is generally limited to patented drugs and includes direct to consumer advertising dtca on broadcast and print media as well as direct to physician promotion dtpp through visits by company representatives to physician offices known as detailing free samples provided to physicians and advertising in professional journals the largest increase in promotion resulted from the expansion of dtca into broadcast media this expansion was precipitated by the food and drug administration s fda s clarification of the rules governing broadcast advertising in 1997 and 1999 making it feasible for companies to promote via television and radio advertisements dtca spending increased from 150 million in 1993 to 4 24 billion in 2005 these new regulations which allow broadcast dtca remain a controversial policy currently only the united states and new zealand permit such advertising dtca is facing increased scrutiny from congress and consumer groups congressional leaders have contended that dtca raises prescription drug costs and have requested that the policy be revisited 2 some groups maintain that the recent increases in dtca are responsible for the increases in expenditures on prescription drugs the national institute for health care management november 2001 claimed that increases in sales for the 50 most heavily advertised drugs caused 47 8 of the increase in expenditures on prescription drugs growth in prescription drug spending is broadly driven by increases in utilization and price and shifts in the composition of drugs being used all of which may be impacted by dtca dtca can raise the demand for existing drugs and can also affect their price elasticity the increase in demand can be beneficial if it improves adherence donohue et al 2004 bradford et al 2006 or makes individuals aware of the existence of drug therapies for their health conditions expenditures have also increased in part as a result of the fact that newer drugs generally cost more than older drugs and dtca might induce substitution to these newer more expensive drugs which also tend to be more heavily advertised this may be health promoting since newer drugs have been shown to be more effective in improving health than are older drugs lichtenberg and virabhak 2007 treatment through prescription drugs can also be more cost effective than alternative and more intensive therapies inducing some substitution among these forms of care 3 a key component of this question of the extent to which the growth in dtca has contributed to rising prescription drug costs relates to how dtca affects drug prices to the best of our knowledge no prior studies have investigated the impact of dtca on prescription drug prices on a broad scale this study adds to the literature with an empirical investigation of the role of prescription drug promotion in affecting the price of prescription drugs prior studies which have explored the effects of consumer advertising on sales have also generally utilized older data collected prior to 2000 have not differentiated between broadcast and non broadcast dtca and have arrived at mixed conclusions regarding the impact of total dtca on own sales

energy poor or fuel poor what are the differences abstract energy poverty and fuel poverty are descriptors of problems of households energy consumption they are both distinct problems and have been addressed by many researchers organizations and governments cross use of the terms of energy poverty and fuel poverty in published papers is common as an accurate descriptor is the presupposition of research and policy development especially for those who just started to pay attention to this issue this paper compares the definitions research priorities status quo and problems of these two concepts and summarizes the relationship between them the paper suggests that only when the research targets are households who are living in a cold climate and have difficulty in getting access to electricity or modern cooking facilities and in supplying indoor heating with appropriate cost the concepts of energy poverty and fuel poverty have the chance to be broadened and mutually integrated

analysis of energy poverty intensity from the perspective of the regional administration empirical evidence from households in southern europe abstract the current economic situation has increased the number of households in europe experiencing restrictions and or limitations of affordability of energy services demonstrating the urgent need to intervene in those extreme cases in which households suffer the daily consequences of what is internationally defined as energy poverty in such a context this paper presents the results obtained in a case study characterising a sample of 615 households with demonstrated energy poverty in the region of aragon spain in parallel the intensity of energy poverty in the studied cases is examined by measuring the percentage of energy expenditures with respect to income in the households that suffer it and a descriptive analysis of the main determinants of energy poverty in the homes studied is presented as well as the policy implication at regional level

convergence of carbon emissions at the household level in china a distribution dynamics approach abstract since household carbon emissions hces have become a new growing source and a significant contributor to global emissions the reduction of hces is crucial to formulate targeted and effective emission mitigation policies we need to fully understand the characteristics of the distribution and evolution of per capita hces and their urban rural and regional heterogeneity this paper explores the transitional dynamics of per capita hces in china by employing the distribution dynamics approach with panel data compiled at the household level we find that the overall per capita hces are unimodal distribution in the long run and the distribution dynamics of the per capita hces between the urban and rural areas or among the regional subgroups are quite different however the speed of convergence has accelerated over time moreover our findings indicate that the per capita hces in the urban areas will achieve convergence to an emission level much higher than that of the rural areas meantime the per capita hces in northeast china will converge to an emission level much higher than those of the other three regions these findings provide valuable insights for policymakers in implementing differentiated environmental policies for different regions and between urban and rural households in china

the demand for ethanol as a gasoline substitute abstract this paper estimates household preferences for ethanol e85 as a gasoline e10 substitute i develop a theoretical model linking the shape of the ethanol demand curve to the underlying distribution among households of willingness to pay for ethanol i estimate the model using instrumental variables techniques and data from many retail fueling stations i find that a 0 10 per gallon increase in ethanol s price relative to gasoline leads to a 12 16 decrease in the quantity of ethanol demanded my findings imply that preferences for ethanol are heterogeneous and that a substantial fraction of households are willing to pay a premium for the fuel this reduces substantially the simulated efficiency cost of an ethanol content standard since some households choose ethanol without large subsidies mitigating deadweight losses

does regulation drive out competition in pharmaceutical markets abstract most countries regulate pharmaceutical prices either directly or indirectly on the assumption that competition is at best weak in this industry this paper tests the hypothesis that regulation of manufacturer prices and retail pharmacy margins undermines price competition we use data from seven countries for 1992 to examine price competition between generic competitors different manufacturers of the same compound and therapeutic substitutes similar compounds under different regulatory regimes we find that price competition between generic competitors is significant in unregulated or less regulated markets united states united kingdom canada and germany but that regulation undermines generic competition in strict regulatory systems france italy and japan regulation of retail pharmacy further constrains competition in france germany and italy regulation thus undermines the potential for significant savings on off patent drugs which account for a large and growing share of drug

generics and new goods in pharmaceutical price indexes drug prices and their rate of inflation are a major focus of current policy debates on u s health care in this paper we show that where patent expiration and generic entry are significant as they are for many important classes of drugs movements in the official price indexes may be poor indicators of the actual prices paid and the resulting changes in consumer welfare when a drug goes off patent those consumers who regard the branded and generic versions as more or less perfect substitutes experience a substantial price decline and concomitant welfare gain which the current methods used by the statistical agencies fail to capture we suggest a number of alternative ways of proceeding although our computations are based on a limited number of cases they imply that the overall rate of inflation in drug prices may be quite seriously overstated while generic pharmaceuticals are the topic of our calculations the problem discussed is also of wider importance generic drugs are a special and possibly easy case

the influence of managed care on generic prescribing rates an analysis of hmo physicians retail expenditures on prescription drugs continue to grow annually by double digits while the share of prescriptions dispensed as generics remains relatively constant efforts to curtail rising drug expenditures have been exhibited by managed care organizations mcos yet drug expenditures continue to rise using the national ambulatory medical care survey namcs for 1997 2000 this study examines how managed care specifically health maintenance organizations hmos influence the physician s decision to prescribe the generic version of a multi source drug the findings show that hmo physicians are not significantly more likely to prescribe generic drugs than non hmo physicians among hmo physicians different cost reduction tools effect generic prescribing behaviour in different ways with the size of the effect depending on the patient and physician relationship with the hmo

licensing the market for technology abstract in technology based industries incumbent firms often license their technology to potential competitors such a strategy is difficult to explain within traditional models of licensing this paper extends the literature on licensing by relaxing the assumption of a monopolist technology holder competition in the market for technology induces licensing of innovations and incumbent firms may find it privately profitable to license although their joint profits may well be higher in the absence of any licensing a strong testable implication of our model is that the number of licenses per patent holder decreases with the degree of product differentiation

the potential impact of tobacco biopharming the case of human serum albumin biopharming stands to significantly expand the uses of many agricultural crops this article examines the potential size and distribution of welfare gains from biopharming transgenic tobacco as a source of human serum albumin hsa using an economic surplus model under imperfect competition the results suggest that hsa from transgenic tobacco will generate annual profits for the innovating firm of between 25 million and 49 million on the other hand consumers are unlikely to benefit during the patent life of the product given the innovator s market power

regulation and competition in the taiwanese pharmaceutical market under national health insurance this article investigates the determinants of the prices of pharmaceuticals and their impact on the demand for prescription drugs in the context of taiwan s pharmaceutical market where medical providers earn profit directly from prescribing and dispensing drugs based on product level data we find evidence that the profit seeking behavior of the medical providers in the prescription drug market transfers the force of competition from the unregulated wholesale market to the regulated retail market and hence market competition still plays an important role in the determination of the regulated price we also find that the profit seeking behavior plays a similar role to advertising in that it increases the brand loyalty and hence lowers price elasticity an important implication of our study is that the institutional features in the pharmaceutical market matter in shaping the nature of pharmaceutical competition and the responsiveness of pharmaceutical consumption with respect to changes in price

alfred marshall lecture intellectual property rights protection in developing countries the case of pharmaceuticals patent enforcement in developing countries generates considerable controversy especially when patents involve potentially life saving drugs this paper argues that common concerns regarding the effects of patents on prices and on research incentives of pharmaceutical multinationals are misplaced rather the most significant effects are likely to concern access to patented drugs in poor countries because prices in developing countries are much lower than in the developed world multinationals may choose to enter such markets with a delay or not at all implying a complete loss of access to patented drugs in developing countries even when multinationals enter countries like india their marketing and distribution networks are not currently built out leading to limited access within the country such considerations may provide a justification for policies targeting access in the short and medium run such as compulsory licensing

price competition in pharmaceuticals the case of anti infectives a fundamental question in industrial organization regards the relationship between price and the number of sellers this relationship has been particularly important in the pharmaceutical industry where legislative changes were specifically designed to foster competition previous research on the pharmaceutical industry has shown generic entry has a mixed impact generic prices fall rapidly with generic entry whereas branded prices tend to increase or decrease only slightly using more complete data focused on one segment of the pharmaceutical industry anti infectives we find that the relationship between pharmaceutical prices and the number of sellers is more like that found in other industries jel l11 l65 d4

demand estimation and merger simulations for drugs logits v aids abstract we use adhd drugs sales data from 2000 2003 and compare estimates of elasticities and merger simulations from three different demand models models include logit random coefficients logit and conditional aids demand model with multistage budgeting the magnitude of cross price elasticities is larger in the third model in comparison to the first two and some of the cross price elasticities are estimated to be negative hypothetical merger simulations show larger price effects for the multistage aids model in comparison to the discrete choice models

fees versus royalties and the private value of a patent we compare how much profit an owner of a patented cost reducing invention can realize by licensing it to an oligopolistic industry producing a homogeneous product by means of a fixed fee or a per unit royalty our analysis is conducted in terms of a noncooperative game involving n 1 players the inventor and the n firms in this game the inventor acts as a stackelberg leader and it has a unique subgame perfect equilibrium in pure strategies it is shown that licensing by means of a fixed fee is superior to licensing by means of a royalty for both the inventor and consumers only a drastic innovation is licensed to a single producer

by ounce or by calorie the differential effects of alternative sugar sweetened beverage tax strategies the obesity epidemic and excessive consumption of sugar sweetened beverages have led to proposals of economics based interventions to promote healthy eating in the united states targeted food and beverage taxes and subsidies are prominent examples of such potential intervention strategies this paper examines the differential effects of taxing sugar sweetened beverages by calories and by ounces on beverage demand to properly measure the extent of substitution and complementarity between beverage products we developed a fully modified distance metric model of differentiated product demand that endogenizes the cross price effects we illustrated the proposed methodology in a linear approximate almost ideal demand system although other flexible demand systems can also be used in the empirical application using supermarket scanner data the product level demand model consists of 178 beverage products with combined market share of over 90 the novel demand model outperformed the conventional distance metric model in non nested model comparison tests and in terms of the economic significance of model predictions in the fully modified model a calorie based beverage tax was estimated to cost 1 40 less in compensating variation than an ounce based tax per 3 500 beverage calories reduced this difference in welfare cost estimates between two tax strategies is more than three times as much as the difference estimated by the conventional distance metric model if applied to products purchased from all sources a 0 04 cent per kcal tax on sugar sweetened beverages is predicted to reduce annual per capita beverage intake by 5 800 kcal

how to license intangible property we examine the optimal licensing strategy of a research lab selling to firms who are product market competitors we consider an independent lab as well as a research joint venture we show that 1 demands are interdependent and hence the standard price mechanism is not the profit maximizing licensing strategy 2 the seller s incentives to develop the innovation may be excessive 3 the seller s incentives to disseminate the innovation typically are too low 4 larger ventures are less likely to develop the innovation and more likely to restrict its dissemination in those cases where development occurs and 5 a downstream firm that is not a member of the research venture is worse off as a result of the innovation

a multidimensional measure of energy poverty in china and its impacts on health an empirical study based on the china family panel studies abstract inability or insufficient access to modern forms of energy is an important issue in development which makes the notion of energy poverty a widely discussed topic a consensus has been reached that energy poverty has serious health education and other socio economic impacts for people in a country however measurements of energy poverty have generally been absent or inaccurate especially for developing countries at the micro level this paper begins with the multidimensional nature of energy poverty and uses household level survey data in china to construct a quantitative measure of energy poverty covering both affordability of and accessibility to a broad range of forms of energy it then builds an econometric model to address empirically how much energy poverty affects health a statistically significant and robust negative impact on health from energy poverty is confirmed our results have important policy relevance in terms of understanding the current status quo of energy poverty in china and its consequences the concept can also be expanded to investigate similar issues in other developing countries

physician agency and adoption of generic pharmaceuticals i examine physician agency in health care services in the context of the choice between brand name and generic pharmaceuticals i examine micro panel data from japan where physicians can legally make profits by prescribing and dispensing drugs the results indicate that physicians often fail to internalize patient costs explaining why cheaper generics are infrequently adopted doctors respond to markup differentials between the two versions indicating another agency problem however generics markup advantages are short lived which limits their impact on increasing generic adoption additionally state dependence and heterogeneous doctor preferences affected generics adoption policy makers can target these factors to improve static efficiency

meta analysis of empirical evidence on energy poverty the case of developing economies abstract energy poverty has evolved as an important issue of research from academic and policy perspectives during the last two decades the energy poverty estimates exhibit widespread variations across regions methodologies and datasets making the task of energy and development policies challenging the variations in energy poverty estimates necessitate a systematic and rigorous analysis of these empirical studies to obtain a true measure of energy poverty the present study conducts a meta analysis of 30 studies and 103 estimates of energy poverty on average 71 1 percent of the population in the overall sample studies has been identified as energy poor high i square statistic values suggest heterogeneity bias in the sample studies therefore analysis at the subgroup level has been conducted meta regression analysis of overall sample and subgroups has identified type of methodology citations impact factor of the journal regional dummies average key crude oil price and gross domestic product as significant factors that explain heterogeneity in the energy poverty effect sizes we recommend inclusion of local and regional factors in assessment of energy poverty for developing a uniform methodology to assess energy poverty across developing economies

licensing to enhance demand for new technologies this article presents a model in which licensing competitors expands demand for a new proprietary product and therefore may be a profit maximizing strategy for the licensor even when licensing increases industry cost in the model buyers care about price and quality sellers can contract on price but not on quality and a single supplier has monopoly power licensing induces quality competition and allows the supplying firms to make a quality commitment that would not be credible for a single firm as a result licensing increases industry demand and may generate an increase in industry revenue sufficient to offset any increase in industry cost some of the characteristics of the model are informed by observations in the semiconductor industry

product differentiation and oligopoly in international markets the case of the u s automobile industry this paper develops and estimates a model of the u s automobile industry on the demand side a discrete choice model is adopted that is estimated using micro data from the consumer expenditure survey the estimation results are used in conjunction with population weights to derive aggregate demand on the supply side the automobile industry is modelled as an oligopoly with product differentiation equilibrium is characterized by the first order conditions of the profit maximizing firms the estimation results are used in counterfactual simulations to investigate two trade policy issues the effects of the ver and exchange rate pass through

measuring energy poverty focusing on what matters abstract the provision of modern energy services is recognised as a critical foundation for sustainable development and is central to the everyday lives of people effective policies to dramatically expand modern energy access need to be grounded in a robust information base metrics that can be used for comparative purposes and to track progress towards targets therefore represent an essential support tool this paper reviews the relevant literature and discusses the adequacy and applicability of existing instruments to measure energy poverty drawing on those insights it proposes a new composite index to measure energy poverty both the associated methodology and initial results for several african countries are discussed whereas most existing indicators and composite indices focus on assessing the access to energy or the degree of development related to energy our new index the multidimensional energy poverty index mepi focuses on the deprivation of access to modern energy services it captures both the incidence and intensity of energy poverty and provides a new tool to support policy making

divisionalization and entry deterrence this paper assumes that incumbent firms can create new independent divisions more cheaply than potential entrants who must incur the additional overhead costs of new entry the main theoretical result is that such divisionalization ability leads perfectly informed incumbents to preempt all rational entry into their industries in contrast existing models of entry deterrence imply that informed incumbents even those with steadily decreasing average costs will often allow rational entry our result may explain why successful large scale entry by firms with no informational advantage is extremely rare the use of divisions to preempt entry may also explain why large firms in high profit oligopolies often divisionalize allowing their divisions to compete freely despite the negative pecuniary externality that each division imposes on others

the role of firm characteristics in pharmaceutical product launches this paper examines the determinants of new pharmaceutical launches since 1980 in the g7 nations using discrete time hazard models despite the obvious incentive to amortize the large sunk costs of drug development over many markets entry occurs in only 4 of the opportunities the results indicate that firm characteristics such as domestic status and experience in the local market are important in explaining product launches in addition to market characteristics also the interaction between the innovating firm and target country is a critical component of profitability new drugs are 1 5 times more likely to be launched in markets that share a border or a language of a drug company s country of headquarters even for multinational firms the effect of competition depends on the characteristics of both the potential entrant and the incumbents domestic entrants prefer to compete with domestic incumbents although this is an industry with the potential for ubiquitous licensing and low transportation costs the specific match quality between the innovating firm and market conditions remains an important determinant of entry
