delivering bad news market responses to negligence abstractone of the goals of the legal liability system is to ensure that sellers provide appropriate care reputation effects may also deter negligence the little available research evidence suggests that reputation effects are minimal however we develop a theory tailored to an environment such as medicine in which sellers are of heterogeneous quality and face two types of demand private consumers who exhibit downward sloping demand for example private health insurance and government consumers who exhibit perfectly elastic demand at a fixed price for example medicaid insurance the theory predicts that high quality sellers who suffer reputation losses will see their caseloads shift from private to government patients while low quality sellers will lose government patients and may gain private patients combining individual patient level data from florida for the years 1994 2003 with physician level litigation data we find evidence that physicians experience reputation effects that are consist

the relationship between the markets for health insurance and medical malpractice insurance this article evaluates the interdependence of medical malpractice insurance markets and health insurance markets prior research has addressed the performance of these markets individually without specifically quantifying the extent to which they are linked increasing levels of health insurance losses could increase the scale of potential malpractice claims boosting medical malpractice losses or could embody an improvement in medical care quality which will reduce malpractice losses our results for a state panel data set from 2002 to 2009 demonstrate that health insurance losses are negatively related to medical malpractice insurance losses an additional dollar of health insurance losses is associated with a 0 01 0 05 reduction in medical malpractice losses these findings have potentially important implications for assessments of the net cost of health insurance policies

does medical malpractice law improve health care quality we assess the potential for medical liability forces to deter medical errors and improve health care treatment quality identifying liability s influence by drawing on variations in the manner by which states formulate the negligence standard facing physicians using hospital discharge records from the national hospital discharge survey and clinically validated quality metrics inspired by the agency for health care research and quality we find evidence suggesting that treatment quality may improve upon reforms that expect physicians to adhere to higher quality clinical standards we do not find evidence however suggesting that treatment quality may deteriorate following reforms to liability standards that arguably condone the delivery of lower quality care similarly we do not find evidence of deterioration in health care quality following remedy focused liability reforms such as caps on non economic damages awards

do doctors practice defensive medicine defensive medicine is a potentially serious social problem if fear of liability drives health care providers to administer treatments that do not have worthwhile medical benefits then the current liability system may generate inefficiencies much larger than the costs of compensating malpractice claimants to obtain direct empirical evidence on this question we analyze the effects of malpractice liability reforms using data on all elderly medicare beneficiaries treated for serious heart disease in 1984 1987 and 1990 we find that malpractice reforms that directly reduce provider liability pressure lead to reductions of 5 to 9 percent in medical expenditures without substantial effects on mortality or medical complications we conclude that liability reforms can reduce defensive medical practices

endogenous market structures in international trade natura facit saltum abstract almost all of the large literature on international trade with imperfect competition assumes exogenous market structures the purpose of this paper is to develop a simple model that generates alternative market structures as nash equilibria for different parameterizations of the basic model equilibrium market structure is a function of the underlying technology familiar configurations such as a duopoly competing in exports or a single multinational producing in both markets arise as special cases small tax policy changes can produce large welfare effects as the equilibrium market structure shifts implying discontinuous jumps in prices quantities and profits

pricing and patents of hiv aids drugs in developing countries this article provides empirical evidence on the impact of patents on drug prices across developing countries it uses sales data on human immunodeficiency virus hiv acquired immuno deficiency syndrome aids drugs in a sample of 34 low and middle income countries between 1995 and mid 2000 the main findings are that patents do shift drug prices up drug prices are correlated to per capita income levels and drug firms follow a skimming strategy when pricing new hiv aids drugs that is there is across country and intertemporal price discrimination in the global drug markets

hedonic price indexes for spreadsheets and an empirical test for network externalities in this article i first estimate hedonic price equations for computer spreadsheet programs and then use the analysis to empirically test whether network externalities exist in this industry the study shows that consumers are willing to pay a significant premium for spreadsheets that are compatible with the lotus platform and for spreadsheets that offer links to external databases and a similar premium for spreadsheets that offer local area network externalities finally the quality adjusted real price of computer spreadsheets declined by approximately 15 per year from 1986 to 1991

house prices home equity based borrowing and the u s household leverage crisis us household leverage sharply increased in the years preceding the 2007 eco nomic recession the top panel of figure 1 shows the steady rise in household debt since 1975 which accelerated beginning in 2002 in just five years the household sector doubled its debt balance in comparison the contemporaneous increase in corporate debt was modest the middle panel shows that the increase in household debt from 2002 to 2007 translated into a striking rise in household leverage as mea sured by the debt to income ratio during the same time period corporate leverage declined the dramatic absolute and relative rise in us household leverage from 2002 to 2007 is unprecedented compared to the last 25 years one reason for the rapid expansion in household leverage during this period is that mortgage credit became more easily available to new home buyers mian and sufi 2009 strong house price appreciation from 2002 to 2006 however which may have been fueled by the availability of mortgage credit to a riskier set of new home buyers could also have had an important feedback effect on household lever age through existing homeowners given that 65 percent of us households already owned their primary residence before the acceleration in house prices the feedback from house prices to borrowing may be an important source of the rapid rise in household leverage that preceded the economic downturn our central goals in this study are to estimate how homeowner borrowing responded to the increase in house prices and to identify which homeowners responded most aggressively we examine this home equity based borrowing channel using a dataset consisting of anonymous individual credit files of a national consumer credit bureau agency we follow a random sample of over 74 000 us homeowners who owned their homes as of 1997 at an annual frequency from the end of 1997 until the end of 2008 the bottom panel of figure 1 plots the growth in debt of 1997 homeowners over time and shows that existing homeowners borrow significantly more debt as their house prices appreciate from 2002 to 2006 while the aggregate trend is suggestive

the consequences of the growth of health insurance premiums in the united states two thirds of the nonelderly population is covered by employerprovided health insurance ehi according to a kaiser family foundation national survey 2003 the cost of ehi has increased by over 59 percent since 2000 with no accompanying increase in the scale or scope of benefits these increases in health insurance premiums may have significant effects on labor markets including changes in the number of jobs hours worked per employee wages and compensation packages indeed it is possible that a significant portion of the increase in the uninsured population may be a consequence of employers shedding this benefit as health insurance premiums rise understanding how labor market characteristics affect adjustments to increased health insurance costs is of vital policy importance some proposals to cover the uninsured rely on employer mandates requiring employers to cover eligible workers other proposals provide tax credits for the purchase of non employer health insurance the effects of these proposals on employment wages and health insurance coverage will be driven by the elasticities of labor supply and demand institutional constraints on wages and compensation packages and how much workers value the increase in health insurance costs since employers provide such coverage voluntarily if workers fully value these benefits and are able to sort between firms based on their preferences then in the absence of other institutional constraints they will bear the cost of the increase via reduced wages with no accompanying change in employment employment costs or employee utility there are many reasons to believe however that firms are limited in their ability to offset increases in the price of health insurance premiums through lower compensation so that increases in the cost of providing health insurance may affect both employment and the structure of work identifying the magnitude of these effects empirically is difficult both because of data availability and because of multiple avenues for causality in this paper we uncover the causal effect of increases in the cost of benefits on labor market outcomes by exploiting an exogenous source of variation in the cost of providing health insurance the recent medical malpractice crisis in which malpractice costs for physicians grew dramatically in some states but not in others the growth in malpractice payments affects malpractice insurance premiums and health insurance premiums but it should not affect other aspects of employment see baicker and chandra 2005b using this source of variation we examine the effect of increases in health insurance premiums on employment patterns earnings and health insurance coverage we find that the cost of increases in health insurance premiums is borne in large part by workers through increased unemployment and also through decreased hours for those workers moved from full time jobs with benefits to parttime jobs without these results have strong implications for the distributional impact of health care reforms both authors economics department dartmouth college 6106 rockefeller hall hanover nh 03755 dartmouth medical school and national bureau of economic research e mails kbaicker dartmouth edu achandra dartmouth edu we thank alan garber seth seabury jonathan skinner and douglas staiger for helpful conversations that have influenced this research program and derek neal aaron yelowitz and conference participants at the berger conference for very insightful comments we are grateful for funding from nia p01 ag19783 02 the opinions in this paper are those of the authors and should not be attributed to the nia or nber 1 based on tabulations of population under age 65 from the march current population survey for 1988 2003 2 there is a wide literature estimating the wage fringe trade off a 1 increase in the value of fringes may be offset by a 1 reduction in wages or a 1 1 tax rate reduction for tax favored benefits for example jonathan gruber 1994 demonstrates that the passage of the pregnancy discrimination act in 1978 resulted in employers shifting the entire cost of the mandate onto employees

the econometrics of damage control why specification matters the contribution of damage control agents to production differs fundamentally from that of standard inputs lands labor capital this paper develops an econometric model based on the key characteristics of damage control agents and examines its properties it demonstrates that standard production function specifications overestimate damage control agent productivity and have erroneous implications for the evolution of damage control agent productivity and use in response to changing environments e g the spread of pest resistance it also proposes several alternative specifications and discusses methods for estimating them

the labor market effects of rising health insurance premiums we estimate the effect of rising health insurance premiums on wages employment and the distribution of part time and full time work using variation in medical malpractice payments driven by the recent medical malpractice crisis we estimate that a 10 increase in health insurance premiums reduces the aggregate probability of being employed by 1 2 percentage points reduces hours worked by 2 4 and increases the likelihood that a worker is employed only part time by 1 9 percentage points for workers covered by employer provided health insurance this increase in premiums results in an offsetting decrease in wages of 2 3

competition in regional environmental policies when plant locations are endogenous abstract a two region model is presented in which an imperfectly competitive firm produces a good with increasing returns at the plant level production of the good causes local pollution the firm decides whether to maintain plants in both regions serve both regions from a single plant or shut down if the disutility of pollution is high enough the two regions will compete by increasing their environmental taxes standards until the polluting firm is driven from the market alternatively if the disutility from pollution is not as great the regions will usually compete by undercutting each other s pollution tax rates

the role of targeted communication and contagion in product adoption the two main influences leading to adoption at the individual consumer level are marketing communication and interpersonal communication although evidence of the effect of these two influences is abundant at the market level there is a paucity of research documenting the simultaneous effect of both influences at the individual consumer level thus the primary objective of this paper is to fill the gap in the literature by documenting the existence and magnitude of both influences at the individual customer level while controlling for unobserved temporal effects the pharmaceutical industry provides an appropriate context to study this problem it has been conjectured that adoption and usage patterns of a new drug by physicians contagion acts as a consumption externality as it allows a given physician to learn about the efficacy and use of the drug in addition pharmaceutical companies target individual physicians via marketing activities such as detailing sampling and direct to consumer adverti

cross border acquisitions and taxes efficiency and tax revenues we develop a theoretical oligopoly model to study how international differences in profit and capital gains taxes affect foreign acquisitions reductions in foreign profit taxes tend to trigger inefficient foreign acquisitions while reductions in foreign capital gains taxes may trigger efficient foreign acquisitions foreign acquisitions can increase domestic tax revenues even when profit taxes are evaded the reason is that bidding competition between foreign firms ensures that all benefits from the acquisition including tax advantages are captured by a domestic seller paying capital gains taxes tax code issues such as the treatment of goodwill are shown to affect the pattern of foreign acquisitions jel classification f23

information marketing and pricing in the u s antiulcer drug market introduced into the united states in 1977 tagamet was the pioneer product in the class of antiulcer drugs known as h2antagonists by promoting ulcer healing through inhibiting acid secretion tagamet was able to heal ulcers and treat pre ulcer conditions pharmacologically on an outpatient basis thereby substituting for more costly hospital admissions and surgeries in 1983 another h2 antagonist called zantac entered and by early 1987 u s zantac sales surpassed those of the pioneering tagamet today there are four h2 antagonists sold in the united states tagamet zantac pepcid and axid zantac is now the world s largest selling prescription drug having estimated worldwide sales in 1994 of about 4 billion each of the four h2 antagonists is among the top 100 in world drug sales although tagamet lost u s patent protection on may 17 1994 in this paper we examine empirically the role of information in facilitating and explaining growth of the overall antiulcer drug market as well as in shaping the changing market shares of the four patented products the dissemination of information is due largely to the use of marketing channels such as visits by manufacturers representatives to physicians called detailing advertising in medical journals and most recently by direct to consumer advertising we examine these and also explore pricing policies product differentiation and orderof entry effects

learning and payoff externalities in an investment game abstract this paper examines the interplay of informational and payoff externalities in a two player irreversible investment game each player learns about the quality of his project by observing a private signal and the action of his opponent i characterize the unique symmetric equilibrium in a timing game that features a second mover advantage allowing for arbitrary correlation in project qualities despite private learning the game reduces to a stochastic war of attrition in contrast to the case of purely informational externalities all investments happen at the same real time instant irrespective of the sign of the correlation and beliefs never get trapped in a no learning region provided that the second mover advantage is sufficiently high

the impact of liability on the physician labor market abstract this study examines the impact of malpractice reforms on physician behavior using a new measure of liability risk and a nationally representative individual level data set on physician behavior we match our liability measure to data on physician behavior from the physician practice costs and income survey ppcis data from the ppcis bracket a period of substantial state level legal reform between 1983 and 1988 which provides identifying variation in our liability measure we estimate the impact of liability reform on hours worked we find an estimated elasticity of hours worked to liability exposure of 285 for the full sample of physicians the effect for physicians ages 55 or older is much larger we find an elasticity of 1 224 for this category we find that an increase in 1 of expected liability is associated with a 70 1 05 increase in malpractice premiums

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

fdi policies under shared factor markets abstract we examine the consequences of foreign direct investment fdi policies in a general equilibrium setting with several oligopolistic industries by shifting labor demand across countries fdi raises the wage in the host country and lowers the wage in the source country thereby raising profits of source country firms at the expense of host country firms the extent of cross ownership of firms the relative number of firms and the relative supply of skilled labor alter the impact of fdi policy on national welfare the tension between profits and wages determines whether the optimal policy is designed to encourage fdi

the impact of hospital market structure on patient volume average length of stay and the cost of care a variety of recent proposals rely heavily on market forces as a means of controlling hospital cost inflation sceptics argue however that increased competition might lead to cost increasing acquisitions of specialized clinical services and other forms of non price competition as means of attracting physicians and patients using data from hospitals in 1972 we analyzed the impact of market structure on average hospital costs measured in terms of both cost per patient and cost per patient day under the retrospective reimbursement system in place at the time hospitals in more competitive environments exhibited significantly higher costs of production than did those in less competitive environments

learning about new products an empirical study of physicians behavior i introduction an important aspect of economic innovation is the development of new products thus firms often devote large amounts of resources to research and development the pharmaceutical industry in particular is characterized by a high degree of product innovation and significant investments in research and development 1 critical to the adoption of a new pharmaceutical however is the willingness of physicians to prescribe it although clinical trials and advertising convey information about the quality of a new pharmaceutical considerable uncertainty remains not only about its general quality but also about its effect on individual patients 2 because physicians ultimately resolve this uncertainty by prescribing the new drug 3 to their patients namely by experimentation the adoption of a new pharmaceutical is closely related to the experimentation process by which physicians gain information in this paper we focus on the entry of a new antiulcer drug omeprazole in the italian pharmaceutical market in june of 1990 4 our data consist of monthly prescriptions of antiulcer medications by physicians in the rome metropolitan area between june 1990 and december 1992 we develop and estimate a dynamic discrete choice model of physician bayesian learning about the quality of a new drug in our model physicians have initial beliefs about the new drug s efficacy and update them every time that they prescribe the new drug and observe the treatment outcome when choosing which drug to prescribe to a particular patient a forward looking physician considers not only the expected outcome for that patient but also the opportunity to learn about the new drug s quality and use the information on future patients our parameter estimates allow us to disentangle how uncertainty about the new drug s quality intertemporal preferences and prices affect the adoption of the new drug and the corresponding health outcomes a recent literature has explored the role of learning about pharmaceuticals 5 as noted by manchanda et al 2005 in their review of this literature some important aspects of the learning mechanism are the channels through which agents learn prescription detailing marketing meetings and events their preferences toward risk risk averse or risk neutral and whether they are short sighted myopic or forward looking myopic agents maximize their current expected utility while forward looking agents evaluate their current utility as well as the expected future value of the information they might gain through the current prescription 6 the studies also differ in whether they use physician level or aggregate data a central contribution of our paper is the prediction of market demand for the new drug through a parsimonious yet behaviorally rich model using the same physician level data used here coscelli and shum 2004 model the behavior of doctors who learn in a bayesian fashion yet are myopic we in contrast model the forward looking behavior of physicians and reject the null hypothesis that physicians are myopic according to our estimates myopic behavior significantly delays the adoption of the new drug and generates large losses to patients health crawford and shum 2005 use related patient level data and model how forward looking patients learn about their curative and symptomatic matches with respect to alternative medications in their model a patient s learning about a medication is not driven by the fact that the medication is new rather it is driven by her need to learn which medication suits her best hence she learns about her match to each medication not just the new one in our model however learning is driven by the market level uncertainty associated with omeprazole as a new product 7 while it would be of interest to study both doctors and patients learning our doctor level data motivate our focus on physician learning

nonprofit hospital mergers and the exercise of market power government challenges to mergers within the hospital industry have become more frequent many of those mergers involve nonprofit organizations rather than the for profit firms that are the norm in most other industries this difference in ownership has made no apparent difference in the antitrust agencies approach to proposed hospital mergers in this article i test the proposition that nonprofit and for profit hospitals price differently in response to the structure of the markets in which they compete based on a cross sectional analysis of california hospitals i find that estimated merger effects on hospital prices do vary by type of ownership in response to either higher market share or to the joint combination of higher share and higher market concentration private nonprofit hospital prices are statistically significantly lower than for profit hospital prices and on balance in this sample there is no evidence of any systematic price increasing effect on private nonprofit hospitals

competition for firms in an oligopolistic industry the impact of economic integration we set up a model of generalised oligopoly where two countries of different size compete for an exogenous but variable number of identical firms the model combines a desire by national governments to attract internationally mobile firms with the existence of location rents that arise even in a symmetric equilibrium where firms are dispersed as economic integration proceeds equilibrium taxes initially decline but then rise again as trade costs fall even further a range of trade costs is identified where economic integration raises the welfare of the small country but lowers welfare in the large country

bidding for firms recently toyota sought a plant location in the united states the 800 million plant will employ 3000 workers and numerous states offered toyota generous investment incentives hoping this would induce toyota to select their state the commonwealth of kentucky won this competition but the price was high the present value of the payments exceeds 125 million the payment of investment incentives for the toyota plant is not unique in 1976 pennsylvania paid 75 million to attract a volkswagen plan nissan honda and mazda received generous investment incentives when locating plants in the united states and this bidding is not limited to states to attract the headquarters of the presbyterian church usa with its 1300 jobs and 38 million annual payroll civic leaders in louisville kentucky offered the church a warehouse and 6 2 million for renovation of the structure bidding the church away from kansas city missouri in this paper we contend that this competition may result from the average cost pricing of publicly provided goods and services 2 when the marginal cost of providing a firm and its workers with public services is less than the tax revenue they generate a government may offer the firm subsidies that reduce the distortions the average cost pricing of the public service creates thus this competition for industry is not a zero sum game where the subsidies are only transfers from the government to the firm rather these subsidies may facilitate the efficient location of industry

liability insurance under the negligence rule we analyze the e ciency properties of the negligence rule with liability insurance when the tort feasor s behavior is imperfectly observable both by the insurer and the court e ciency is shown to depend on the extent to which the evidence is informative on the evidentiary standard for nding negligence and on whether insurance contracts can condition directly on the same evidence as used by courts to assess behavior when evidence is not directly contractible the negligence rule with compensatory damages is generally ine cient

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

regional tax coordination and foreign direct investment this paper analyses the effects of a regionally coordinated profit tax or location subsidy in a model with three active countries one of which is not part of the union and a globally mobile firm we show that regional coordination can lead to two types of welfare gain first for investments that would take place in the union in the absence of coordination a coordinated tax increase can transfer location rents from the firm to the union second by internalising all of the union s benefits from foreign direct investment a coordinated tax reduction can attract more welfare enhancing investment than when member states act in isolation depending on which motive dominates tax levels may thus rise or fall under regional coordination

strategic pricing of new pharmaceuticals this paper provides empirical evidence on the leading factors affecting the prices of new pharmaceuticals both at introduction and after 4 6 and 8 years most important is the extent of therapeutic advance embodied in a new product for drugs which represent important therapeutic gains launch prices can be two or three times those of existing drugs used for the same purposes while drugs that largely duplicate the actions of currently available products are typically priced at comparable levels in addition the number of branded substitutes has a substantial negative effect on launch prices which reflects the importance of competitive pressures duplicate products thereby play an important economic role in pharmaceutical markets

price and concentration in hospital markets the switch from patient driven to payer driven competition perhaps the most widely accepted paradigm of industrial organization i o is that competition lowers prices or alternatively that price cost margins are lower in less concentrated markets 1 the applicability of this paradigm for hospital markets has been questioned for example in united states vs carilion health system and roanoke valley hospital the district and appellate courts accepted evidence that hospital prices are lower in more concentrated markets and thereby approved a merger between the two largest hospitals in a three hospital market 2 the view that competition has a weak or perverse effect on hospital prices is shared by a number of researchers 3 is a common theme in newspaper stories

estimating marginal returns to medical care evidence from at risk newborns a key policy question is whether the benefits of additional medical expenditures exceed their costs we propose a new approach for estimating marginal returns to medical spending based on variation in medical inputs generated by diagnostic thresholds specifically we combine regression discontinuity estimates that compare health outcomes and medical treatment provision for newborns on either side of the very low birth weight threshold at 1500 grams first using data on the census of us births in available years from 1983 2002 we find that newborns with birth weights just below 1500 grams have lower one year mortality rates than do newborns with birth weights just above this cutoff even though mortality risk tends to decrease with birth weight one year mortality falls by approximately one percentage point as birth weight crosses 1500 grams from above which is large relative to mean infant mortality of 5 5 just above 1500 grams second using hospital discharge records for births in five states in available years from 1991 2006 we find that newborns with birth weights just below 1500 grams have discontinuously higher charges and frequencies of specific medical inputs hospital costs increase by approximately 4 000 as birth weight crosses 1500 grams from above relative to mean hospital costs of 40 000 just above 1500 grams under an assumption that observed medical spending fully captures the impact of the very low birth weight designation on mortality our estimates suggest that the cost of saving a statistical life of a newborn with birth weight near 1500 grams is on the order of 550 000 in 2006 dollars

competition for foreign direct investments abstract this paper models international competition for foreign direct investment as a common agency problem using the theory of menu auctions developed by bernheim and whinston in the model national governments act as principals and a multinational corporation as the single agent governments are assumed to maximize the net wage income generated by the corporation s investment it is shown that in the equilibrium of this game a high wage country may be able to attract investment even though all countries use subsidies furthermore it is shown that a country may choose to pay the highest subsidies even if it attracts less investment than in the unsubsidized regime our framework can also be used to study interregional subsidy competition within a country

the effects and policy implications of state aids to industry an economic analysis state aids making eu policy properly reflect geography and subsidiarity the use of state aids to industry is a poorly understood part of competition policy currently the eu commission presumes that state aids distort competition yet it approves 98 of applications often for social or distributional reasons we argue that proper regulation of state aids should focus on two issues the externalities generated and the inefficiencies arising from failures in competition between governments we thus develop a new framework for eu policy and compare its implications with the existing practice of the eu commission timothy besley and paul seabright

simple econometrics of pesticide productivity this paper develops a multioutput generalization of the lichtenberg zilberman damage control technology the dual representation of the technology is shown to be conditionally additive in the price of abatement activities and other prices an econometric procedure for estimating the dual technology is developed and applied to an aggregate u s agricultural data set the conditionally additive nature of the model allows estimation of pest damage from the dual technology our estimates of aggregate u s pest damage are much lower than previous estimates

multinational corporations economic and human rights impacts on developing countries a review and research agenda developing countries are attracting a significant portion of global foreign direct investments governments of such countries often compete fiercely for attracting multinational corporations mncs in the expectation of the advantages they will bring to their economies often prioritising economic goals over fundamental human rights for a long time economists have analysed the economic impacts of mncs while a parallel strand of work in political science business ethics and international law investigates the repercussions of mnc operations on human rights despite the significant relatedness and complementarities these two bodies of literature have so far poorly interacted this paper addresses this limitation and systematically analyses and integrates existing micro level empirical evidence on the economic and human rights impacts of mncs on developing countries it provides a critical analysis of what is known and highlights what we do not know about the factors that mediate the positive and or negative impacts of mnc operations on host developing countries based on a critical analysis of the literature it discusses avenues for future research in this field and sets the grounds for a new interdisciplinary research agenda on this subject

competition and efficiency in the end stage renal disease program abstract estimated coefficients for medical service production or cost functions are subject to a competitive amenity bias which may result in the failure to identify factors that affect economic efficiency our investigation of productivity of dialysis facilities did indeed indicate both the likelihood of bias and some qualitative results these results suggest that it will be difficult to estimate cost and that variation in the level of reimbursement will in competitive markets affect the level of amenity delivered to patients incurred cost amenity and patient well being will all vary positively with the reimbursement level determining the right level of reimbursement requires a policy decision on how much total amenity society wishes to deliver to beneficiaries of public programs

commitment efficiency and footloose firms the authors consider dynamic competition between a small number of local governments to attract a single large plant the surplus available in each location is unknown when the initial location decision is made two cases are considered if all agents can commit to second period actions and if they cannot without commitment initially the firm will discriminate against the region with the lower set up costs if first period productivity is low the firm may relocate and receive an ex post subsidy from a second region commitment decreases the expected total surplus and if fixed costs are small favors the firm copyright 1992 by the london school of economics and political science

learning from the behavior of others conformity fads and informational cascades learning by observing the past decisions of others can help explain some otherwise puzzling phenomena about human behavior for example why do people tend to converge on similar behavior why is mass behavior prone to error and fads the authors argue that the theory of observational learning and particularly of informational cascades has much to offer economics business strategy political science and the study of criminal behavior

malpractice law and health care reform optimal liability policy in an era of managed care abstract because fee for service health insurance insulates providers from the costs of treatment decisions it may lead to defensive medicine precautionary treatment with minimal expected medical benefit administered out of fear of legal liability by giving providers higher powered incentives managed care may affect optimal liability policy among elderly medicare beneficiaries with heart disease in 1984 1994 we find that liability reducing tort reforms reduce defensive practices in areas with high and low managed care enrollment but that managed care and liability reform are substitutes we consider some implications of these results for the current debate over the appropriateness of extending malpractice liability to managed care organizations

environmental kuznets curve in china new evidence from dynamic panel analysis this paper applies a panel of 28 provinces of china from 1996 to 2012 to study the impacts of economic development energy consumption trade openness and urbanization on the carbon dioxide waste water and waste solid emissions by estimating a dynamic panel model with the system generalized method of moments gmm estimator and an autoregressive distributed lag ardl model with alternative panel estimators respectively we find that the environmental kuznets curve ekc hypothesis is well supported for all three major pollutant emissions in china across different models and estimation methods our study also confirms positive effects of energy consumption on various pollutant emissions in addition we find some evidence that trade and urbanization may deteriorate environmental quality in the long run albeit not in the short run from policy perspective our estimation results bode well for chinese government s goal of capping greenhouse emissions by 2030 as outlined in the recent china us climate accord while containing energy consumption and harm effects from expanding trade and urbanization remains some environmental challenges that china faces

policy competition for foreign direct investment between asymmetric countries the present paper analyses policy competition for foreign direct investment between countries of different size and different market structure we demonstrate how policy competition affects the location decision of the foreign investor and derive welfare implications the key variables in our analysis are intra regional trade costs differences in market size and minimum wages

damage control and increasing returns the indirect action of damage control inputs means the marginal productivity of these inputs depends on their effectiveness in controlling the level and size of production loss caused by the damage agent increasing returns to damage control inputs can occur even when control and damage functions are concave the result implies more attention needs to be paid to the functional form selection for damage and control functions in empirical work on pest control and other types of damage control inputs in addition the possibility of increasing returns may undermine the general use of taxes to reduce pesticide use

asymmetric tax competition abstract the paper analyzes nash equilibrium when two jurisdictions set tax rates on a tax base which is mobile between them population differences imply tax differences the smaller jurisdiction levies a lower tax rate in equilibrium and its residents are better off than those in the larger jurisdiction the nash equilibrium is inefficient if the two jurisdictions merged the resulting allocation would be efficient however if differences in population are great enough residents of the small jurisdiction would be made worse off by such a merger

competition among hospitals the traditional view of hospital competition has posited that hospitals compete primarily along quality dimensions in the form of fancy equipment to attract admitting physicians and pleasant surroundings to entice patients price competition among hospitals is thought to be non existent this paper estimates the effects of various hospital market characteristics on hospital prices and expenses in an attempt to determine the form of hospital competition the results suggest that both price and quality competition are greater in markets that are less concentrated although the net effect of the two on prices is insignificant it appears therefore that despite important distortions hospital markets are not immune to standard competitive forces

identifying industry margins with price constraints structural estimation on pharmaceuticals we develop a structural model to investigate the effects of pharmaceutical price regulation on demand and on manufacturers price setting behavior in france we estimate price cost margins in a regulated market with price constraints and infer whether these constraints are binding exploiting cost restrictions across drugs which come from observing the same drugs in potentially price constrained markets france and in markets where prices are unregulated us and germany our counterfactual simulations suggest that price constraints generated modest savings for anti ulcer drugs in 2003 2013 2 percent of total expenses relative to a free pricing scenario and shifted consumption from generic to branded drugs

another look at pesticide productivity and pest damage using the lichtenberg zilberman fox weersink damage specification we develop a short run supply response framework based on rational producer behavior in the presence of damage agents we show how representation can be used to measure and decompose the economic damage associated with the presence of pests how to measure the shadow prices of damage control agents how to measure the manner in which pesticide application biases variable input use and how pesticide application affects the relative returns to quasi fixed factors of production an econometric version of the model is estimated using a panel data set on greek olive producers both our theoretical and our empirical results suggest that the most traditional measure of pest damage understates actual economic losses and revenue losses due to pests

when does privatization work the impact of private ownership on corporate performance in the transition economies this paper compares the performance of privatized and state firms in the transition economies of central europe while controlling for various forms of selection bias it argues that privatization has different effects depending on the types of owners to whom it gives control in particular privatization to outsider but not insider owners has significant performance effects where privatization is effective the effect on revenue performance is very pronounced but there is no comparable effect on cost reduction overlooking the strong revenue effect of privatization to outsider owners leads to a substantial overstatement of potential employment losses from postprivatization restructuring

profit taxation and the mode of foreign market entry abstract this paper studies the role of profit taxation for an international firm s decision upon how to penetrate a foreign market through exports or through foreign direct investment fdi and local supply we show that with harmonized taxes the international firm may choose fdi even though this has welfare costs from a global point of view with tax competition the host country can enforce exporting instead of fdi this leads to a nash equilibrium associated with higher world welfare than harmonized taxes thus because of the effect on entry mode tax competition provides heretofore unexplored benefits as compared to tax harmonization

estimating substitution and expansion effects using a profit function framework this study reports a first attempt to derive all the relevant information with respect to the structure of production of an industry using knowledge of only a profit function using estimates of a profit function for canadian agriculture a procedure to separate substitution and expansion effects for both inputs and outputs was implemented information concerning net input and output substitution and complementarity possibilities were obtained the most important empirical results suggest that the hypothesis of nonjoint production of crop and animal outputs in canadian agriculture cannot be rejected and that hired and operator labor are complements rather than substitutes

the economics of networks a survey of the empirical literature network effects the increase in value of consuming a product if many other consumers use the same product are a feature of many markets and in particular of many high technology products this paper surveys the burgeoning empirical literature that has developed especially during the last years after theoretical work dominated the earlier years of research in this area newer research has combined theoretical models with empirical studies and applied work with direct implications for public policy marketing and company strategies furthermore insights from the study of social networks have been applied to analyse how consumers interact with each other the paper argues that a closer analysis of the network structure of consumer interaction promises fruitful future research avenues and advances in our understanding of how network effects operate copyright 2009 blackwell publishing ltd

the tragedy of bird scaring abstract this paper examines crop raids by birds in semi arid kenya highlighting the importance of bird scaring as a barrier to the greater adoption of drought resilient high value traditional crops hvtcs in the region using survey data from tharaka nithi county we find 100 of millet and sorghum farmers in the study area scare birds from their plot devoting 43 66 of all labour time to this activity when these crops are grown in monocrop plots and 24 47 of labour time in plots where millet and sorghum are grown in combination with other crops this labour allocation is in stark contrast to farmers of all other crops who dedicate almost no time to bird scaring individually scaring birds from their plot farmers achieve a momentary pareto optimal perpetuating a ripple effect whereby the negative cost of birds are continuously shifted from one farmer to the next we systematically examine this cost shifting behaviour as an externality theoretically applying environmental and resource economics ere policy prescriptions for externality internalisation ere however with its focus on self interest rational actors and technological interventions falls short to present effective solutions to this so called externality farmers in the region can address crop raids by birds through collective coordinated action at this scale the negative cost of pests is deliberately distributed across all receptors leading to long term community wide social wellbeing improvements

is hospital competition socially wasteful we study the consequences of hospital competition for medicare beneficiaries heart attack care from 1985 to 1994 we examine how relatively exogenous determinants of hospital choice such as travel distances influence the competitiveness of hospital markets and how hospital competition interacts with the influence of managed care organizations to affect the key determinants of social welfare expenditures on treatment and patient health outcomes in the 1980s the welfare effects of competition were ambiguous but in the 1990s competition unambiguously improves social welfare increasing hmo enrollment over the sample period partially explains the dramatic change in the impact of hospital competition

personal selling elasticities a meta analysis abstract this article presents a meta analysis of prior econometric estimates of personal selling elasticity that is the ratio of the percentage change in an objective ratio scaled measure of sales output e g dollar or unit purchases to the corresponding percentage change in an objective ratio scaled measure of personal selling input e g dollar expenditures the authors conduct a meta analysis of 506 personal selling elasticity estimates drawn from analyses of 88 empirical data sets across 75 previous articles they find a mean estimate of current period personal selling elasticity of 34 they also find that elasticity estimates are higher for early life cycle stage offerings higher from studies set in europe than from those set in the united states and smaller in more recent years in addition elasticity estimates are affected significantly by analysts use of relative rather than absolute sales output measures by cross sectional rather than panel data by omission of promotions by lagge

the economics and econometrics of damage control concern for the potentially harmful side effects of agricultural chemical inputs especially pesticides highlights the need to accurately determine the economic levels of their use we consider three model specification issues interaction of direct production inputs with damage control inputs in damage abatement justification for a priori exclusion of production inputs from the abatement function and the motivations and consequences of alternative stochastic specifications empirical analysis using farm level data shows that misspecification of the stochastic element in the production function can overestimate the marginal physical productivity of pesticides and grossly underestimate the responsiveness of demand to increases in pesticide prices

adoption curves and social interactions this paper considers the observational implications of social influences on adoption decisions for an environment of perfect foresight adopters we argue that social influences can produce two observable effects 1 discontinuities in unconditional adoption curves and 2 pattern reversals in conditional adoption curves in which earlier adoption is found for one group of actors versus another when fundamentals suggest the reverse ordering should occur in turn the presence of either of these features can under weak assumptions be interpreted as evidence of social influences as such these properties are robust implications of social effects jel c40 d01 o33

the impact of medical liability standards on regional variations in physician behavior evidence from the adoption of national standard rules i explore the association between regional variations in physician behavior and the geographical scope of malpractice standards of care i estimate a 30 50 percent reduction in the gap between state and national utilization rates of various treatments and diagnostic procedures following the adoption of a rule requiring physicians to follow national as opposed to local standards these findings suggest that standardization in malpractice law may lead to greater standardization in practices and more generally that physicians may indeed adhere to specific liability standards in connection with the estimated convergence in practices i observe no associated changes in patient health jel i11 i18 j44 k13 a large literature in health economics and medicine has explored the regional practice patterns of physicians and other medical providers and has endeavored to understand i why some regions spend so much in the care of patients relative to other regions and ii whether high spending regions generate superior health outcomes in this paper i explore a potential contribution to the observed disparities in care that has been suggested by leading theoretical scholars in the area variations literature phelps 1992 but that has yet to be explored empirically laws respecting the geographical nature of the standards of care employed in medical malpractice actions in addition to shedding potentially valuable light on each of the above puzzles this investigation may at the same time offer novel insight into the fundamental question of whether physicians are responsive to the specific standards expected of them under the law a common thread that emerges throughout those studies that have endeavored to explore the causes behind the regional variations phenomenon is the inability

the production effects of agricultural income support policies under uncertainty this analysis decomposes the production impacts of income support programs into wealth insurance and coupling effects under the usual assumptions about preferences the wealth and insurance effects of many support programs increase optimal input levels even for supposedly decoupled programs if the program is coupled in the usual sense then all three effects often act in the same direction it is concluded that studies of trade and domestic policy reform in stochastic environments should consider insurance and wealth effects the derivative conditions required to obtain results are also subjected to scrutiny simulations for an iowa corn producer confirm the comparative statics

competing for a duopoly international trade and tax competition we analyse the tax subsidy competition between two potential host governments to attract the plants of rms in a duopolistic industry competition between identical countries for a monopoly rm s plant is known to result in subsidy in ation which leaves the winning country indierent towards hosting the rm in sharp contrast we show that with two rms both are taxed in equilibrium and the host countries appropriate the entire social surplus generated within the industry despite the explicit non cooperation between governments we extend our baseline model to allow for dierences in country size we investigate when this size asymmetry becomes su ciently large to change the nature of the equilibrium inducing concentration of production in the larger country

competing technologies and market dominance standard battles in the local area networking industry the rise of fast ethernet as the dominant standard for high speed connection in the local area networking industry is chosen to study the interaction between increasing returns to adoption and technical change in innovation diffusion contrary to most of the empirical papers on diffusion with increasing returns which study competition between an entrenched technology and a new competitor the focus is on the case in which several and different versions of a new technology are competing at the same time for market dominance within this context this article studies under which conditions an early technology may fail to capitalise on its initial time advantage and a new version without a clear early lead may become dominant in particular we will consider a case in which the initial time advantage is made ineffective by consistently adverse technological expectations then we analyse how the arrival on the market of different categories of buyers sensitive to specific applications further contribute to weaken the early leader and strengthen a competing version this is more likely to occur when buyers are highly familiar with the characteristics of that specific version copyright 2008 oxford university press

public health insurance and medical treatment the equalizing impact of the medicaid expansions abstract we investigate the impact of expanding public health insurance on the medical treatment received by women at childbirth using vital statistics data on every birth in the us over the 1987 1992 period the effects of insurance status on treatment are identified using the tremendous variation in eligibility for public insurance coverage under the medicaid program over this period among low education mothers who were largely uninsured before being made eligible for medicaid eligibility for this program was associated with significant increases in the use of a variety of obstetric procedures among women with more education however there is a countervailing effect on procedure use most of these women had private insurance before becoming medicaid eligible and some may have been crowded out onto the public program moving from insurance which reimburses medical care more generously to insurance with much less generous reimbursement this movement was accompanied by reductions in procedure use thus on net the medicaid expansions had an equalizing effect increasing the treatment intensity of the previously uninsured while lowering it among the previously insured

models of technology diffusion abstract the literature on new technology diffusion is vast and it spills over many conventional disciplinary boundaries this paper surveys the literature by focusing on alternative explanations of the dominant stylized fact that the usage of new technologies over time typically follows an s curve the most commonly found model which is used to account for this model is the so called epidemic model which builds on the premise that what limits the speed of usage is the lack of information available about the new technology how to use it and what it does the leading alternate model is often called the probit model which follows from the premise that different firms with different goals and abilities are likely to want to adopt the new technology at different times in this model diffusion occurs as firms of different types gradually adopt it there are actually many ways to generate an s curve and the third class of models which we examine are models of density dependence popularized by population ecologists in these models the twin forces of legitimation and competition help to establish new technologies and then ultimately limit their take up finally we look at models in which the initial choice between different variants of the new technology affect the subsequent diffusion speed of the chosen technology such models often rely on information cascades which drive herd like adoption behaviour when a particular variant is finally selected

innovation and recurring shifts in industrial leadership three phases of change and persistence in the camera industry abstract this study examines factors underlying three phases of change or persistence in industrial leadership in the sector of interchangeable lens cameras over the past century during this period there were two major phases of leadership change both associated with the emergence of innovations involving major discontinuities in the industry s core technologies first japan won market leadership from germany in the mid 1960s after commercializing the single lens reflex slr camera that replaced the previously dominant german rangefinder camera second in the late 2000s japanese latecomer firms and a korean firm developed mirrorless cameras which allowed them to capture the majority of market share from the incumbent japanese leaders we also examine the long period about 60 years between these two phases of change during which leading japanese firms were able to sustain their market leadership despite the digital revolution from the 1980s to 1990s this paper explores the factors influencing these contrasting experiences of change and persistence in industry leadership the analysis integrates several aspects of sectoral innovation systems i e windows of opportunity associated with technology demand and institution as well as the strategies of incumbents and latecomer firms the conclusions highlight the complex and diverse combinations and importance of the factors that help explain the patterns of shifts in leadership

malpractice risk and medical treatment selection abstract we study how legal and financial incentives affect medical decisions using patient level data from italy we identify the effect of a change in medical liability pressure by exploiting the geographical distribution of hospitals across court districts where some districts increase the predictability of expected damages per injury while others do not using a difference in differences identification strategy we show that as certainty of compensation increases c sections increase by 6 5 percentage points there is no statistically significant effect on secondary health outcomes of either mothers or newborns but the increase is higher for low risk than high risk mothers the increase is driven by hospitals that have lower quality are governed by inefficient court districts face lower expected damages and are paid more per c section

malpractice law physicians financial incentives and medical treatment how do they interact abstractthe effects of malpractice law and financial incentives on physicians are typically studied independently this paper shows that to make both positive and normative statements about medical malpractice liability one must consider physicians legal and financial incentives jointly i develop a simple model to show that when treatment is unprofitable at the margin mitigation of liability lowers treatment levels conversely when treatment is profitable mitigation of liability raises them motivated by this simple theoretical framework i analyze the impact of a tort reform in texas that mitigated malpractice liability consistent with the theory the rate of cesarean sections among commercially insured mothers for whom the procedure is considered profitable increased by 2 percentage points relative to the rate of cesarean sections among mothers covered by medicaid for whom the procedure is thought to be unprofitable

information and diffusion of new prescription drugs this article examines the role of different product information flows on the diffusion of new pharmaceuticals given the innovative nature of pharmaceutical drugs and their impact on health care expenditure there is a surprisingly small literature devoted to this topic some information flow mechanisms have been examined individually in the literature but very few have captured the simultaneous impact of these mechanisms on up take and diffusion this article uses the up take of statins as an example diffusion of this therapeutical group is expressed as a function of four specific informational channels self experience consumption externalities scientific evidence and marketing in addition to this the influence of economic factors is tested to examine whether they have any role in drug diffusion prescription data from over 130 general practitioners gp practices in the uk during 1991 2004 are used to test the econometric specification applying dynamic panel data methods results suggest individual self experience and clinical evidence are major factors promoting diffusion while there is an inverse relationship with gp practice size and diffusion having controlled for these factors financial incentives and marketing appear to play little role

does regulation of physicians reduce health care spending the medical community argues that physician fear of legal liability increases health care spending theoretically though the effect could be positive or negative and empirical evidence has supported both cases previous studies however have ignored the fact that physicians face risk from industry oversight groups like state level medical licensing boards in addition to civil litigation risk this article addresses this omission by incorporating previously unused data on punishments by oversight groups against physicians known as adverse actions along with malpractice payments data to study state level health care spending my analysis suggests that contrary to conventional wisdom spending does not rise in response to increased risk an increase in adverse actions of 16 the year to year average is associated with statistically significant annual decreases in state spending on hospital care of approximately 22 million and on prescription drugs of nearly 10 million malpractice payments are estimated to have smaller statistically insignificant effects

an economic analysis of technology in the meat products industry the meat products industry underwent significant structural change during the last two decades the relocation and expansion of commercial cattle feeding stimulated development of new single species slaughtering facilities to replace older multi species plants an essentially new processing industry arose specializing in breaking and packaging carcasses this forward integration has significantly changed distribution methods of slaughtering and fabricating firms increased emphasis on coordination of inputs led to interest in backward integration from packing into cattle feeding the steer and heifer slaughtering sector which was decentralized and competitive in the 1950s has turned toward centralization and concentration although the largest firm accounted for only 13 of total u s steer and heifer slaughter in 1977 it had more than doubled its share since 1970 in 1978 this firm slaughtered more than twice as many steers and heifers as its nearest competitor in addi

first do no harm tort reform and birth outcomes in the 1980s and 1990s many states adopted tort reforms it has been argued that these reforms have reduced the practice of defensive medicine arising from excess tort liability we find that this does not appear to be true for a large and important class of cases childbirth in the united states using data from national vital statistics natality files on millions of individual births from 1989 to 2001 we ask whether specific tort reforms affect the types of procedures that are performed and the health outcomes of mothers and their infants we find that reform of the joint and several liability rule or the deep pockets rule reduces complications of labor and procedure use whereas caps on noneconomic damages increase them we show that these results are consistent with a model of tort reform that explicitly allows for variations in patient condition

panel data estimation techniques and farm level data models econometric models wishing to estimate relevant parameters for agricultural policy analysis are increasingly relying on unbalanced panels of farm level data since in the agricultural economics literature such models have often been estimated through simplified approaches in this paper we try to verify whether the adoption of more sophisticated panel data techniques may impact the estimation results for this reason the policy model by moro and sckokai 1999 has been re estimated using techniques recently developed in the econometric literature the preliminary results show a strong impact on the estimations this seems to suggest that the adoption of proper panel data techniques is likely to be very important in order to obtain reliable estimates of some key policy parameters

damage control econometrics functional specification and pesticide productivity empirical studies of pesticide productivity have often concluded that the value of marginal product of pesticide exceeds marginal factor cost despite anecdotal and other evidence to the contrary this article presents estimates of pesticide productivity derived from alternative functional specifications of pesticide involvement in production results suggest that explanation of the magnitude of pesticide productivity estimates obtained in empirical studies may lie somewhere other than with functional specification

perception spillovers across competing brands a disaggregate model of how and when abstract drawing on the accessibility diagnosticity framework and previous literature on branding and order of entry the authors hypothesize that perception spillovers can also occur across directly competing products that do not share a common brand name the authors suggest two mechanisms prior perception spillover and dynamic perception spillover and one moderating variable product brand similarity to test for spillovers across competing brands the authors develop a structural bayesian learning model and estimate it using prescription choice and marketing communication data from a panel of physicians from their model results the authors find evidence of prior and dynamic perception spillovers across competing brands only when brands are sufficiently similar in contrast they find no evidence of spillover effects across brands that are highly dissimilar finally several policy experiments illustrate the strength and significance of competitive spillovers for product diffusion and from the re

on the welfare effects of competition for foreign direct investments abstract this paper investigates welfare effects of subsidy competition for the location of a multinational enterprise one of the competing regions benefits more from the inward investment but in the absence of incentives the multinational s preferred location is the other more advanced region the paper shows that subsidies by making the multinational switch location may increase aggregate welfare if the multinational exports in the absence of incentives the welfare effects of subsidy competition may look very different allowing subsidies attracts the direct investment which otherwise would not take place in one of the two regions further it intensifies competition in the market the paper shows that the welfare increasing role of incentives may be amplified but also that the competition effect by hurting domestic firms may cancel out any other positive role of incentives

an analysis of the factors determining the geographical distribution of japanese manufacturing investment in the uk 1984 91 the purpose of this paper is to discover which factors have been important in determining the geographical distribution of japanese manufacturing establishments in the uk during 1984 91 a multivariate statistical analysis is undertaken based on the poisson model to investigate the inter county variation in the number of establishments locating in each uk county during two separate time periods 1984 88 and 1989 91 in addition to examining the influence of variables such as labour costs labour availability and industry mix on the locational choice of japanese firms the statistical analysis attempts to capture the influence of regional policy multivariate regression analysis reveals that the geographical distribution of japanese owned investment in the uk is only statistically associated with a small number of variables the main explanatory variable in the model is whether an area had assisted area status other key explanatory variables are those reflecting an area s industry mix

industrial blackmail dynamic tax competition and public investment a dynamic model of intergovernmental competition for a large plant is presented when local productivity is uncertain one firm determines the location of its plant in each period by conducting an auction soliciting bids from local governments equilibrium subsidies from the local governments are derived the author also consider a two stage game where local governments first choose a level of costly infrastructure then participate in the sequential auction even when costs are identical across locations investing in different levels of infrastructure is a nash equilibrium moreover when infrastructure is endogenous in this manner it is chosen efficiently

legal systems institutional environment and food safety in the aftermath of the recent food scares the united states and the united kingdom face major challenges to maintain a safe food system regulators on opposite sides of the atlantic are facing rapid product and process innovations changes in consumption behaviors expansion of international trade and discovery of new food hazards the u k and the u s demonstrate different approaches to manage safety risks this article will focus on two issues the reasons behind the differences in the american and english policy approaches to food safety and how these differences impact u s safety outcomes a comparative legal framework is provided to understand how food safety is elicited in the economy and the incentive implications of the different institutional settings these two different lenses because they differ so teach us about the fundamental sources of safety the u k s prevalent doctrine is parliamentary sovereignty and leads to a regulatory framework while the u s is based on constitutional supremacy and relies on a legal framework the source of safety under a regulatory framework is the government bureaucracy while the u s legal framework provides an important point of departure the constitutional standing of the firm and the consumer we argue that while the u k system is structured to work through a regulatory framework to enhance the supply of safety in the economy the u s system is much less directed the legal system the subject of this article plays an important role not only in discouraging breach but also in acting as a check on the discretionary authority of the regulator in the end the u s and the u k may have equally safe food systems but what differs is the fundamental source of the safety supply the practical implication is that safety in the food system emerges from several sources not just through regulation therefore direct importation of u k style regulatory approaches may not be effective within a u s constitutional setting
