tariff effects on mnc decisions to engage in intra firm and arm s length trade using confidential firm level data from the bureau of economic analysis bea on activities of u s multinational corporations mncs and their canadian affiliates we study the dramatic growth of intra firm and arm s length u s canada trade over the 1984 95 period we find that decisions to engage in intra firm and arm s length trade are essentially unrelated to tariff and transport cost reductions over this sample period thus we find that the increase in trade occurred almost entirely on the intensive rather than the extensive margin this is consistent with case study evidence in keane and feinberg 2006 where mnc executives consistently indicate that the modest tariff reductions of the 1984 95 period were not sufficient to justify fixed costs of overhauling international supply chains our results have important implications for recent influential models of international trade that rely on sensitivity of intra firm trade to tariffs at the extensive margin to explain how small tariff declines could have led to the explosion of intra firm trade since the 1980s we also find that initial conditions i e 1983 tariffs are uncorrelated with whether firms engaged in intra firm or arm s length trade activity at the start of the sample period this result is surprising as it implies that firms industries with a greater propensity to engage in trade were not in general successful at lobbying for more favourable tariff treatment a l aide de donnees confidentielles au niveau de la firme du bureau of economic analysis bea a propos des activites des firmes plurinationales fpn americaines et de leurs succursales canadiennes on etudie la croissance dramatique du commerce usa canada tant intra firme qu a bout de bras pour la periode 1984 95 il appert que les decisions de s engager dans l un et l autre commerce sont fondamentalement non reliees aux reductions des couts de transport et des tarifs au cours de cette periode on decouvre que l accroissement du commerce s est produit presqu entierement a la marge intensive plutot qu a la marge extensive c est en ligne avec les resultats de l etude de cas de keane et feinberg 2006 ou les cadres des fpn ont systematiquement indique que les modestes reductions de tarifs entre 1984 et 1995 n etaient pas suffisantes pour justifier les couts fixes impliques par la modification de leurs chaines de production internationales ces resultats ont des implications importantes pour certains modeles influents de commerce international qui sont ancres dans une sensibilite du commerce intra firme aux tarifs a la marge extensive pour expliquer comment de faibles chutes de tarifs ont pu engendrer une explosion du commerce intra firme depuis les annees 80 on montre aussi que les conditions initiales e g les tarifs de 1983 ne sont pas co reliees avec le fait que la firme est engagee ou non dans l un ou l autre commerce en debut de periode le resultat est surprenant parce qu il implique que firmes et industries ayant une plus grande propension a commercer n ont pas eu de succes dans leur lobby pour obtenir un traitement tarifaire plus favorable

when is external debt sustainable the article empirically examines the determinants of debt distress defined as periods in which countries resort to any of three forms of exceptional finance significant arrears on external debt paris club rescheduling and non concessional international monetary fund lending probit regressions show that three factors explain a substantial fraction of the cross country and time series variation in the incidence of debt distress the debt burden the quality of policies and institutions and shocks the relative importance of these factors varies with the level of development these results are robust to a variety of alternative specifications and the core specifications have substantial out of sample predictive power the quantitative implications of these results are examined for the lending strategies of official creditors

tradeoffs from integrating diagnosis and treatment in markets for health care anyone who has consulted a doctor plumber or auto mechanic has experienced the tradeoffs in consulting a single expert to both diagnose and treat a problem in the presence of asymmetric information on one hand integrated diagnosticians those who also sell treatments may have the incentive to give advice that is not in the buyer s best interests as the theoretical models in curtis r taylor 1995 and asher wolinsky 1993 point out because the buyer has imperfect information on the scope of the problem if he did not he would not have needed to consult a diagnostician in the first place the diagnostician inevitably has the incentive to recommend treatments that are more profitable even if they are more costly of lower quality or less appropriate on the other hand joint production of diagnosis and treatment may be more efficient the diagnostician may have better information about how to treat the problem than he could or would provide to an independent third party or the diagnostician may be able to treat the problem himself less expensively or more effectively half the cost is opening the engine block we examine an important special case of this problem the costs and quality of care of a random sample of medicare beneficiaries with coronary artery disease we compare patients who were diagnosed by an integrated cardiologist one who also provides surgical treatment to patients who were diagnosed by a nonintegrated cardiologist we decompose the total effect of diagnosis by an integrated cardiologist into the parts due to the change in the type of treatment and the parts due to the relative efficiency of each type of treatment with this information we quantify the potential upsides and downsides to diagnosis by an integrated expert we identify these effects based on differences across geographic areas in the number of integrated cardiologists per capita our estimates are consistent under the assumption that unobserved patient characteristics and other determinants of spending are similar across areas with many versus few integrated cardiologists we explore the validity of this assumption below the paper proceeds in four sections section i reviews the previous empirical literature on the problems of obtaining diagnosis and treatment from a single expert when that expert has better information than the buyer on the source of the buyer s problem section ii discusses the details of the problem that we study and presents our models section iii describes our data section iv presents our results and section v concludes with the implications of our results for economic theory and health policy

a review of wta wtp studies abstract willingness to accept wta is usually substantially higher than willingness to pay wtp these constructs have been studied for roughly 30 years and with a wide variety of goods this paper reviews those studies we find that the less the good is like an ordinary market good the higher is the ratio the ratio is highest for non market goods next highest for ordinary private goods and lowest for experiments involving forms of money a generalization of this pattern holds even when we account for differences in survey design ordinary goods have lower ratios than non ordinary ones we also find that ratios in real experiments are not significantly different from hypothetical experiments and that incentive compatible elicitation yields higher ratios

entry into pharmaceutical submarkets a bayesian panel probit analysis summary we study entry into pharmaceutical submarkets by using a dynamic panel probit model we develop a bayesian version of wooldridge s approach to dealing with unobserved heterogeneity we distinguish between greenfield entry entry with first product and undifferentiated entry which may take the form of introducing further products we extend the standard reduced form model to consider company size in the submarket and across all submarkets we find that greenfield and undifferentiated entries have different determinants that global and submarket size measures have different effects and that sunk costs often have positive effects on entry due to a commitment mechanism copyright 2012 john wiley sons ltd

the disparity between willingness to accept and willingness to pay measures of value psychologists have long argued that people are much more averse to a loss than attracted to an equivalent gain this behavior termed loss aversion has been formalized by kahneman and tversky 1979 in their reformulation of expected utility theory prospect theory in prospect theory the utility function is replaced by a value function that evaluates changes in income from the current level increases in income are weighted by a relatively small marginal utility decreases in income are weighted by a much larger marginal utility in effect the value function implies that a kink in the relationship between utility and income occurs at the initial income or reference point and that the slope of the utility function for losses in income is steeper than it is for gains in a recent paper knetsch and sinden 1984 report a series of experiments that demonstrate the existence of a large disparity between willingness to accept wta and willingness to pay wtp measures of value they argue that the psychological theory of loss aversion explains this difference economic theory would suggest that individuals who exhibit a large disparity between wta and wtp are perhaps underperceiving the value of gains or overperceiving the value of losses are behaving in an irrational manner and will consequently achieve a lower level of well being than if they behaved in a true utility maximizing manner this would in contrast to loss aversion usually imply near equal values for wta and wtp see willig 1976 further documentation of a larger than expected disparity between wta and wtp has been obtained in surveys asking for the value of a variety of public goods for example cummings brookshire and schulze 1986 document six

endogeneity in brand choice models applications of random utility models to scanner data have been widely presented in marketing for the last 20 years one particular problem with these applications is that they have ignored possible correlations between the independent variables in the deterministic component of utility price promotion etc and the stochastic component or error term in fact marketing mix variables such as price not only affect brand purchasing probabilities but are themselves endogenously set by marketing managers this work tests whether these endogeneity problems are important enough to warrant consideration when estimating random utility models with scanner panel data our results show that not accounting for endogeneity may result in a substantial bias in the parameter estimates

productivity growth in goods and services across the heterogeneous states of america i introduction the study of income and productivity convergence and structural transformation are central and recurring themes in economic growth research the u s states have been a fertile testing ground for many intellectual advances in these areas the closed economy assumptions of the underlying models notwithstanding the states offer compensating advantages such as being subject to the same macroeconomic policy while simultaneously exhibiting considerable heterogeneity along many dimensions of interest to growth researchers demographics composition of output quality of workforce tax policy natural resource endowments geography etc at the same time knowledge on multifactor productivity mfp growth which is central to many growth models remains sparse for u s states this is mainly due to lack of data on capital accumulation beyond the manufacturing sector this is unfortunate as an emerging body of work has begun to draw attention to the fact that the convergence of state level incomes has slowed down over the past two to three decades in the absence of adequate data at the state level it becomes difficult to further analyze this problem within a multisectoral framework in this study we seek to rectify this shortcoming by constructing and analyzing productivity growth for the broadly defined privately produced goods and service sectors at the state level and undertake both growth accounting and convergence analysis for the period 1980 2007 1 our primary innovation is the use of the dual growth accounting method which relies on factor prices rather than factor stocks to construct mfp growth to get a sense of the underlying heterogeneity in sectoral labor productivity growth consider the convergence plots displayed in figure 1 in figure 1 a we plot labor productivity growth in the nonfarm nonmining private sector between 1980 and 2007 against initial labor productivity there is some evidence of absolute convergence although weak in figures ib and 1c we repeat similar plots but now for the goods sector and for the private service sector separately here we see markedly different patterns while convergence in the goods sector is apparent for services it is quite the opposite moreover if one inspects the values on the vertical axes one can also infer large differences across states this is particularly true for goods where the difference between oregon or and montana mt was almost 7 annually as a result even though montana had slightly higher labor productivity in 1980 by 2007 oregon s productivity was at least five times higher even for the service sector where the range is much smaller the difference between connecticut ct and michigan mi was almost 2 annually as a result though both states began with almost similar values connecticut s labor productivity in services was 60 higher than michigan s by 2007 clearly these are large underlying regional differences these very different patterns motivate some of the questions that we try to answer in this study using our constructed series of mfp growth and its constituent variables we examine the sources of variations in labor productivity growth first we conduct an in depth growth accounting exercise to explore the relative importance of mfp growth versus factor accumulation for the two broad sectors across u s states this allows us to undertake traditional growth accounting exercises and also examine the sources of variations across states as the dual accounting approach relies on the construction of real wage growth and real user cost growth we also investigate the sectoral patterns for these two variables second we conduct convergence analysis at the sectoral level for labor productivity growth mfp growth as well as factor price growth we show that while the goods sector shows convergence both absolute and conditional on initial human capital we see no such evidence for the service sector

loss aversion and individual characteristics many studies have shown that loss aversion affects the valuation of non market goods using stated choice data this paper presents an empirical investigation of how individual level loss aversion varies with observable personal characteristics and with the choice context we investigate loss aversion with respect to travel time and money and find significant loss aversion in both dimensions the degree of loss aversion in the time dimension is larger than in the money dimension and depends on age and education subjects tend to be more loss averse when the reference is well established

the british low wage sector and the employment prospects of the unemployed abstractare low wages a way for the unemployed to switch to higher paying jobs using data from the british household panel survey the labour market dynamics of unemployed low paid and higher paid employed men are analysed moreover the respective un employment duration and occupational skill level are accounted for results show that in general low wages significantly reduce the risk of future unemployment and increase the chances of ascending the salary ladder especially in the case of long term unemployment 360 days furthermore the occupational skill level has a substantial influence on the upward mobility of low paid jobs individuals working in the initial period in a low paid and higher skilled occupation have on average an 11 percentage points higher probability of entering higher pay compared to when working in a low paid and low skilled occupation

heterogeneous vertical tax externalities and macroeconomic effects of federal tax changes the role of fiscal advantage abstract how do state tax rates respond to federal tax shocks this paper presents a novel mechanism of heterogeneous vertical tax externalities across state levels of fiscal advantage showing that tax increases can be expansionary even without their reinvestment states rich in natural resources have a fiscal advantage in the inter state competition over production factors which allows them to respond better to increases in federal taxes and consequently attract capital from other parts of the nation we add heterogeneity in fiscal advantage levels to an otherwise standard model of vertical tax externalities and horizontal tax competition the model shows that irrespective of federal redistribution the contractionary effect of a federal tax increase can be overturned in fiscally advantaged states through an increase in their tax base using the case of the u s and narrative based measures of federal tax shocks a la romer and romer 2010 we provide empirical evidence for the various aspects of this mechanism specifically our baseline estimates indicate that controlling for federal transfers a 1 increase in the gdp share of capital related federal taxes at the beginning of a year increases the growth rate of the per capita tax base by approximately 0 7 in high fiscal advantage states at the end of it

a test of the theory of reference dependent preferences eight alternative methods of eliciting preferences between money and a consumption good are identified two of these are standard willingness to accept and willingness to pay measures these methods differ with respect to the reference point used and the dimension in which responses are expressed the loss aversion hypothesis of tversky and kahneman s theory of reference dependent preferences predicts systematic differences between the preferences elicited by these methods these predictions are tested by eliciting individuals preferences for two private consumption goods the experimental design is incentive compatible and controls for income and substitution effects the theory s predictions are broadly confirmed

state dependence and heterogeneity in health using a bias corrected fixed effects estimator this paper considers the estimation of a dynamic ordered probit of self assessed health status with two fixed effects one in the linear index equation and one in the cut points the two fixed effects allow us to robustly control for heterogeneity in unobserved health status and in reporting behaviour even though we can not separate both sources of heterogeneity the contributions of this paper are twofold first it contributes to the literature that studies the determinants and dynamics of self assessed health measures second this paper contributes to the recent literature on bias correction in nonlinear panel data models with fixed effects by applying and studying the finite sample properties of two of the existing proposals to our model the most direct and easily applicable correction to our model is not the best one and has important biases in our sample sizes

valuing environmental commodities some recent experiments a general model of consumer behavior is proposed to assess six recent experiments that have attempted to reveal preferences for environmental goals each experiment used a mix of both the techniques and the theory of demand for non market commodities and each was designed to estimate a non market attitude associated with the environment and to analyze potential biases in the techniques the six cases show some consistency in results the linkage within the contingent market between the environmental attribute institutional setting and the bidding instrument must be realistic and accepted by the respondent to avoid biased results possibly the most important result is the replication of results using a traditional property value study and a contingent bidding approach all evidence obtained to date suggests that hedonic studies of property values or wages travel costs and survey techniques all yield values well one order of magnitude in accuracy 41 references 2 tables

anomalies and stated preference techniques a framework for a discussion of coping strategies this paper introduces a symposium on the issue of how stated preference sp research can best cope with anomalies i e systematic deviations from the predictions of standard economic theory in survey responses it proposes a framework for constructive debate recognising i the legitimate aspirations of sp research ii the relevance of evidence from sources other than best practice sp and iii the precautionary value of investigating strategies for coping with suspected anomalies even if questions about the robustness of anomalies have not been finally resolved five alternative coping strategies discussed in more detail in the symposium are briefly introduced

simple solutions to the initial conditions problem in dynamic nonlinear panel data models with unobserved heterogeneity i study a simple widely applicable approach to handling the initial conditions problem in dynamic nonlinear unobserved effects models rather than attempting to obtain the joint distribution of all outcomes of the endogenous variables i propose finding the distribution conditional on the initial value and the observed history of strictly exogenous explanatory variables the approach is flexible and results in simple estimation strategies for at least three leading dynamic nonlinear models probit tobit and poisson regression i treat the general problem of estimating average partial effects and show that simple estimators exist for important special cases copyright 2005 john wiley sons ltd

a dynamic oligopoly structural model for the prescription drug market after patent expiration this article incorporates consumer learning and heterogeneity into a dynamic oligopoly model for the prescription drug market in the model both firms and patients need to learn the generic qualities via patients experiences generic firms entry decisions are endogenous but their entry timings depend on a random approval process i apply the model to examine the impact of shortening the expected generic approval time although this policy experiment brings generics to the market sooner it increases a potential entrant s likelihood of entering a crowded market and hence could reduce the total number of generic entrants and consumer welfare

the dynamics of health in the british household panel survey this paper considers the dynamics of a categorical indicator of self assessed health using eight waves 1991 1998 of the british household panel survey bhps our analysis has three focal points the relative contributions of state dependence and heterogeneity in explaining the dynamics of health the existence and consequences of health related sample attrition and the investigation of the effects of measures of socioeconomic status with a particular focus on educational attainment and income to investigate these issues we use dynamic panel ordered probit models there is clear evidence of health related attrition in the data but this does not distort the estimates of state dependence and of the socioeconomic gradient in health the models show strong positive state dependence and heterogeneity accounts for around 30 of the unexplained variation in health copyright 2004 john wiley sons ltd

generic drug industry dynamics both the economics literature and the business press suggest that a typical pattern for a new industry or what jovanovic and macdonald 1994 call an invention i s to have an initial phase in which a small number of firms each earn significant profits followed by a phase in which rapid entry of new firms leads to increased competition and dissipation of some of those profits often accompanied by a shakeout whereby only a few large firms remain especially if subsequent innovations increase the optimal scale although this pattern seems to characterize many industries the length of time during which early movers retain their profits how prices adjust during the entry process and the

price information and bidding behavior in repeated second price auctions examining panel data on bidding behavior in over forty second price auction markets with repeated trials we observe that i posted prices influence the behavior of the median naive bidder ii posted prices do not affect the behavior of the median experienced bidder or the bidder for familiar goods and iii anticipated strategic behavior wanes after two trials the results suggest that while affiliation might exist in auctions for new goods the repeated trial design with nonprice information removes the correlation of values and provides the experience that bidders need to understand the market mechanism

state dependence in the incidence of strikes evidence from canadian contract data using heckman s dynamic probit model abstract this paper considers whether there is state dependence in strike incidence using longitudinal contract data from canada i obtain my estimates using heckman s estimator for dynamic probit models and find that there is no state dependence in strike incidence

channels of interstate risk sharing united states 1963 1990 we develop a framework for quantifying the amount of risk sharing among states in the united states and construct data that allow us to decompose the cross sectional variance in gross state product into several components which we refer to as levels of smoothing we find that 39 percent of shocks to gross state product are smoothed by capital markets 13 percent are smoothed by the federal government and 23 percent are smoothed by credit markets the remaining 25 percent are not smoothed we also decompose the federal government smoothing into subcategories taxes transfers and grants to states

country portfolio dynamics this paper presents a general approximation method for characterizing timevarying equilibrium portfolios in a two country dynamic general equilibrium model the method can be easily adapted to most dynamic general equilibrium models it applies to environments in which markets are complete or incomplete and it can be used for models of any dimension moreover the approximation provides simple easily interpretable closed form solutions for the dynamics of equilibrium portfolios

saving investment correlations and capital mobility on the evidence from annual data this paper evaluates the use of saving investment correlations to measure capital mobility it is argued that the intertemporal approach to the balance of payments predicts that the practice of calculating the correlation coefficient using long term averages of saving and investment shares biases the result toward accepting the hypothesis of capital immobility calculations based on annual data show that the correlation coefficient is much lower and that is varies considerably estimates of intranational capital mobility based on saving and investment shares of u s federal states show that the saving and investment link is much looser within a nation than among nations copyright 1992 by royal economic society

discontinuity of output convergence within the united states why has the course changed has the progress of output convergence changed within the united states this article examines the output convergence among u s states for the last five decades by making several improvements over the extant literature by applying a battery of convergence tests designed to capture nonlinear transitional dynamics to real output per worker data i e nominal values deflated by state level price we find that output convergence has not been a feature of the continental united states since the 1970s instead output convergence has proceeded among four subgroups within which constituent states have certain characteristics in common our regression analysis suggests that state level characteristics related to technology and human capital play a crucial role in accounting for the formation and composition of convergence clubs in agreement with the recent theoretical models of growth and development e g aghion et al 2009 gennaioli et al 2013b the level of technology proxied by patents turns out to be a consistently significant determinant even after controlling for endogeneity suggesting that frictions in the diffusion of technology and human capital may have led to clustering of states with different levels of productivity our results therefore cast doubt on the common view that diffusion of knowledge and technology across state borders is frictionless jel o47 o51

measuring financial market integration over the long run is there a u shape abstract using long time series for sovereign bond markets of fifteen industrialized economies from 1875 to 2009 i find that financial market integration by the end of the 20th century was higher than in earlier periods and exhibited a j shaped trend with a trough in the 1920s the main reason for the higher financial integration seen today is the recent extensive globalization around the turn of the 20th century countries frequently drifted apart conversely in recent years the bond markets of most countries have moved together both policy variables and the global market environment play a role in explaining the time variation in integration while unexplained changes in the overall level of country risk are also empirically important my methodology based on principal components analysis is immune to outliers and accounts for global and country specific shocks and hence can capture trends in financial integration more accurately than standard techniques such as simple correlations

estimation of fractional dependent variables in dynamic panel data models with an application to firm dividend policy fractional dependent variables and models with state dependence arise in many economic applications however estimating models with fractional dependent variables is complicated by the presence of two corner solution outcomes when coupled with a dynamic panel data setting estimating quantities of interest can be quite complex or computationally difficult this article demonstrates a method for estimating fractional response variables which is easy to implement and presents an application of the technique to the determination of firm dividend policy the estimation demonstrates that neglecting dynamics unobserved heterogeneity or the doubly censored nature of the dependent variable can generate misleading conclusions

dynamics of female labour force participation in france abstractthis article formulates and estimates a structural intertemporal model of labour force participation relying on theoretical characterizations derived from an economic model of lifetime behaviour we estimate a dynamic probit model with correlated random effects using longitudinal data to allow for a dynamic structure the model is applied to a panel of married women drawn from the 1997 2002 french labour force surveys in order to represent their participation behaviour it is estimated by maximum simulated likelihood our results show that women s decisions to go out to work are characterized by significant state dependence unobserved heterogeneity and negative serial correlation in the transitory error component in addition we find that the presence of young children in a woman s household reduces her labour participation but unequally according to their age and number as expected educational level has a positive impact on women s participation last a rise in the husband s wage is found

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

do anomalies disappear in repeated markets there is some evidence that as individuals participate in repeated markets anomalies tend to disappear one interpretation is that individuals particularly marginal traders are learning to act on underlying preferences which satisfy standard assumptions an alternative interpretation the shaping hypothesis is that individuals preferences are adjusting in response to cues given by market prices the paper reports an experiment designed to discriminate between these hypotheses with particular reference to the disparity between willingness to pay and willingness to accept

the market for elective surgery joint estimation of supply and demand this paper develops models of the demand for and supply of elective non emergency surgery using a panel of quarterly data for 200 english hospitals over the period 1995 2002 unusually distinct measures of supply outpatients seen and inpatient admissions and demand outpatient referrals and decisions to admit are available for each observation these offer the opportunity to estimate separate empirical models of supply and demand using ordinary least squares ols regression methods however the strong correlation between the residuals of these models suggests some merit in the deployment of seemingly unrelated regression sur methods although both static and dynamic sur estimations leave the results largely qualitatively unchanged sur estimation can have a considerable quantitative effect relative to the ols results for example sur estimation generates a lower elasticity of inpatient demand with respect to waiting time than that obtained via ols the results offer an important justification for more careful econometric modelling of hospital behaviour than has traditionally been employed in the health economics literature

ghg registries participation and performance under the canadian voluntary climate challenge program between 1994 and 2004 the voluntary challenge and registry vcr played an important role in canadian climate change policy in this paper we examine the decision of firms to participate in the vcr the extent of their involvement and then ask if greenhouse gas emissions are related to past vcr participation as an information provision program we find evidence that firms may participate in vcr to signal their environmental responsibility to regulators and to some extent investors but not to consumers we also find that past involvement in the vcr is a strong and significant determinant of current involvement in the registry greenhouse gas emissions reported to the mandatory greenhouse gas reporting program in 2004 however do not appear to be different between vcr reporters and non reporters ghg emissions are observed to be significantly lower among firms that are smaller emit fewer toxic releases use more renewable energy sources are intermediate good producers and are located in quebec ontario and manitoba

substitutability experience and the value disparity evidence from the marketplace abstract recent empirical evidence suggests that important disparities exist between willingness to pay and compensation demanded for the same good these results which clearly contradict closely held economic doctrines have led some influential commentators to call for an entirely new economic paradigm to displace conventional neoclassical theory this study examines the generality of these experimental findings by going to a well functioning marketplace and examining more than 350 individual decisions across two incentive compatible elicitation mechanisms the data suggest that behavior of individuals with intense experience approaches neoclassical predictions any observed wta wtp disparity amongst this group is negligible

market simulation and the provision of public goods a non paternalistic response to anomalies in environmental evaluation most normative economics assumes that individuals have coherent preferences this paper responds to growing evidence of failures of this assumption particularly in the context of stated preference methods widely used in environmental policy analysis it proposes a non paternalistic concept of consumer sovereignty that does not assume preference coherence is satisfied by competitive markets and can be applied to the provision of public goods a key implication is that decisions should reflect valuations revealed at the point of consumption such valuations which can be inferred from hedonic prices may be less susceptible to willingness to accept wta willingness to pay wtp disparities than those elicited by stated preference methods

adding asymmetrically dominated alternatives violations of regularity and the similarity hypothesis an asymmetrically dominated alternative is dominated by one item in the set but not by another adding such an alternative to a choice set can increase the probability of choosing the item that dominates it this result points to the inadequacy of many current choice models and suggests product line strategies that might not otherwise be intuitively plausible

testing for choice dynamics in panel data this article applies different approaches to distinguish state dependence from unobserved heterogeneity and serial correlation and hence test for state dependence in consumer brand choices first we apply a simple method proposed by chamberlain which involves lagged exogenous variables only second we also estimate a lagged dependent variable specification proposed by wooldridge third we use the estimation approach suggested by wooldridge to estimate a model with both lagged dependent and exogenous variables to distinguish between the two different sources of choice dynamics state dependence and lagged effects of the exogenous variables our analysis reveals that the best approach is to use models with both lagged dependent and exogenous variables our findings include strong evidence for state dependence in five out of the six product categories studied in this article

persistence of innovation in dutch manufacturing is it spurious this paper studies the persistence of innovation and the dynamics of innovation output in dutch manufacturing using firm data from three waves of the community innovation surveys cis pertaining to the periods 1994 1996 1996 1998 and 1998 2000 we estimate by maximum likelihood a dynamic panel data type 2 tobit model accounting for individual effects and handling the initial conditions problem we find that there is no evidence of true persistence in achieving technological product or process innovations while past shares of innovative sales condition albeit to a small extent current shares of innovative sales

no money no honey financial versus knowledge and demand constraints on innovation the paper adds to the literature on the barriers to innovation in two ways first we assess comparatively what mostly constrains firms ability to translate investment in innovation activity into new products and processes whether it is mainly finance as most of the literature would suggest or whether it is mostly knowledge and market related aspects second we suggest a method to correct for the sample selection bias that often affects empirical contributions to this scholarship by filtering out firms that are not interested in innovation from those that struggle to engage in it we obtain a relevant sample of potential innovators which allows us to analyse the comparative effect of financial and non financial barriers on innovation success we find that demand side factors particularly concentrated market structure and lack of demand are as important as financial constraints in determining firms innovation failures this evidence redirects attention from financial to non financial barriers by considering traditional demand market structure and regulation factors involved in reduced firm innovation performance the empirical analysis is based on an unbalanced panel of firm level data from four waves of the uk community innovation survey cis between 2002 and 2010 merged with data from the uk business structure database

exchange economies and loss exposure experiments exchange economies were created in which individuals faced losses if people are risk seeking in the losses as predicted by prospect theory then due to the nonconvexity the competitive equilibria are all on the boundaries of the edgeworth box the experimental results are that risk seeking behavior is observed in many people and appears in markets as predicted in addition market behavior is consistent with answers to hypothetical questionnaires contrary to prospect theory risk seeking seems to diminish with experience preferences in the market setting are not labile and risk seeking preferences are not simply a result of framing effects copyright 1997 by american economic association

whose wages do unions raise a dynamic model of unionism and wage rate determination for young men we estimate the union premium for young men over a period of declining unionization 1980 87 through a procedure which identifies the alternative sources of the endogeneity of union status while we estimate the average increase in wages resulting from union employment to be in excess of 20 we find that the return to unobserved heterogeneity operating through union status is substantial and that the union premium is highly variable we also find that the premium is sensitive to the form of sorting allowed in estimation moreover the data are consistent with comparative advantage sorting our results suggest that the unobserved heterogeneity which positively contributes to the likelihood of union membership is associated with higher wages we are unable however to determine whether this is due to the ability of these workers to extract monopoly rents or whether it reflects the more demanding hiring standards of employers faced by union wages 1998 john wiley sons ltd

the effect of inertia on brand name versus generic drug choices abstract consumers tendency to repurchase products is called inertia this study investigates inertia in brand name and generic drug choices which is manifested by the slow and limited adoption of generic drugs despite their lower prices we use claims data from japan and focus on the generic entry of a widely prescribed lipid lowering drug pitavastatin observing the periods before and after the generic entry gives us a unique opportunity to identify the effect of inertia we construct a choice model that incorporates price heterogeneous brand preferences and inertia to quantify each component s magnitude we find that both inertia and heterogeneity in brand preferences have substantial effects counterfactual simulations suggest that a nudging policy that removes inertia from previous brand name users such as by alerting the patients to switch to cheaper generic drugs may have substantial effects and enable patients to choose optimally

coping with preference anomalies in cost benefit analysis a market simulation approach this paper proposes a methodological strategy for cost benefit analysis cba which does not require the assumption that individuals preferences satisfy standard coherence conditions and so renders cba immune to the problems generated by preference anomalies the proposal treats cba as an exercise in market simulation based on the measurement of surplus anomalies occur when surplus measurements vary according to the hypothetical payment mechanism used in such cases the mechanism that is the closest market analogue should be used this approach is used to resolve problems associated with some familiar anomalies including inconsistencies between citizen and consumer valuations and endowment effects

neoclassical theory versus prospect theory evidence from the marketplace several experimental studies have provided evidence that suggest indifference curves have a kink around the current endowment level these results which clearly contradict closely held economic doctrines have led some influential commentators to call for an entirely new economic paradigm to displace conventional neoclassical theory e g prospect theory which invokes psychological effects this paper pits neoclassical theory against prospect theory by investigating data drawn from more than 375 subjects actively participating in a well functioning marketplace the pattern of results suggests that prospect theory adequately organizes behavior among inexperienced consumers but consumers with intense market experience behave largely in accordance with neoclassical predictions moreover the data are consistent with the notion that consumers learn to overcome the endowment effect in situations beyond specific problems they have previously encountered this transference of behavior across domains has important implications in both a positive and normative sense

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

modeling heterogeneity and state dependence in consumer choice behavior in frequently purchased consumer goods markets consumer brand choices exhibit substantial persistence across purchase occasions in this article i estimate a choice model that admits of both heterogeneity in preferences and true state dependence as sources of this persistence using nielsen scanner data on ketchup i find evidence for true state dependence in the choice process even after controlling for a rich heterogeneity structure simulation of the model indicates that the long term effect of a promotion induced purchase on future purchase probabilities is positive but small

willingness to pay and willingness to accept how much can they differ comment i agree with the point made by edoh y amiran and daniel a hagen 2003 that there can be a substantial or even infinite divergence between the wta and wtp for a public good even where there is a nonzero elasticity of substitution between market goods and the public good provided that the indifference curves are asymptotically bounded with respect to market goods in the manner they describe this is an important point they are also correct to point out that the elasticity of substitution is a local concept whereas their asymptotic boundedness condition applies also for discrete changes my 1991 paper used a local analysis because it was following the structure of the analysis in robert d willig 1976 and alan randall and john r stoll 1980 i wanted to show that while randall and stoll appeared to extend willig s local result on wta versus wtp from price changes to changes in the quantity of a public good the relevant elasticity was in fact different and involved the substitution elasticity as well as the income elasticity i view these points by amiran and hagen as not two separate results but essentially the same result their asymptotic boundedness condition generalizes my zero elasticity of substitution condition to discrete changes the asymptotic boundedness condition can be expressed as follows assuming a bivariate utility function u x q and given a reference point x q associated with a reference utility level u u x q there exists some q q such that for all q q there exists no x such that u x q u in other words no amount of x can substitute for the reduction in public good from q to q q in the case of a zero elasticity of substitution q q but as amiran and hagen show in their theorem 1 this is unnecessarily restrictive when dealing with a discrete reduction in q furthermore their theorem 2 can be viewed as a special case of their theorem 1 in which q 0 which makes q an essential commodity it is well known in consumer theory that the wta to avoid the loss of an essential market good is infinite their theorem 2 extends this result to the case of an essential nonmarket good but as their theorem 1 shows essentialness is not necessary for an infinite wta the boundedness condition is the key and this implies a fundamental lack of substitutability between money market goods and the public good

using hicksian surplus measures to examine consistency of individual preferences evidence from a field experiment this paper pits neoclassical theory against prospect theory by investigating several clean tests of the competing hypotheses consistent with previous work the field experimental data suggest that prospect theory adequately organizes behavior among inexperienced consumers whereas consumers with intense market experience behave largely in accordance with neoclassical predictions the data indicate that the convergence in values occurs entirely because of lower hicksian equivalent surplus values

third party intervention and the preservation of bargaining relationships this article uses longitudinal bargaining contract data to examine whether third party dispute resolution procedures improve the health of bargaining relationships and contribute to their preservat

does government funding complement or substitute private research funding to universities abstract there is growing political pressure on universities to intensify their interaction with industry and to enlarge their own research funding options in a context characterised by increasing constraints on public spending however whether the successful achievement of such a political desired outcome is consistent with a restriction of government funding is not clear and requires further investigation as a matter of fact there is scant empirical evidence on whether and to what extent government funding affects the external funding options available to universities in particular those related to research and consulting activities by using a set of probit and tobit panel data models estimated on financial data for the whole population of italian university departments engaged in research in the engineering and physical sciences this paper provides evidence that government funding to universities complements funding from research contracts and consulting contributing to increasing universities collaboration with industry and activating knowledge transfer processes

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

scientific numerology preference anomalies and environmental policymaking recently an abundance of experimental evidence has been gathered that is consonant with the notion that individual preferences are inconsistent and unstable these empirical results potentially undermine the theoretical foundation of welfare economics as the degree of preference lability claimed suggests that perhaps no optimization principles underlie even the most straightforward of choices yet policymakers in the environmental arena continue to prescribe policies based on economics based methods that are constructed on the very principles that have been directly refuted are policymakers creatures of habit that move at glacial speed or is there something deeper behind their inertness in this study i explore this issue within the u s context and argue that there is some rationality behind current public policy decisionmaking i then explore whether the empirical evidence supports the view that policymakers should take preference anomalies seriously as a case study i focus on some of my recent findings on preference inconsistencies in the marketplace

poverty and social exclusion two sides of the same coin or dynamically interrelated processes there is growing interest in the analysis and measurement of social exclusion to complement the static and dynamic literature on income poverty on theoretical grounds social exclusion and income poverty are seen as different processes but with closely interrelated dynamics however our empirical understanding of the way these two processes dynamically interact at the individual level is still very limited to shed some light on the issue we use a dynamic bivariate probit model controlling for unobserved heterogeneity and wooldridge 2005 type initial conditions both the first and second order markov dynamics are examined we estimate the model using the italian sample of the european community household panel echp waves 1 8 and find a sizable extent of state dependence in both poverty and social exclusion moreover there are dynamic cross effects implying that poverty and social exclusion are mutually reinforcing social policies aimed at eradicating poverty and avoiding individuals social

poverty transition and persistence in ethiopia 1994 2004 summary this study analyzes the persistence of poverty in both rural and urban areas in ethiopia during 1994 2004 the key finding is that households move frequently in and out of poverty but the difficulty of exiting from poverty like the chance of avoiding slipping back increases with the time spent in that state and varies considerably between male and female headed households our results imply that it is important to design anti poverty policies both to hinder households from slipping into extreme poverty and to minimize the length of the poverty spell for households once they have fallen into it

does institutional quality resolve the lucas paradox the lucas paradox observes that capital flows predominantly to relatively rich countries contradicting the neoclassical prediction that it should flow to poorer capital scarce countries in an inf

split panel jackknife estimation of fixed effect models we propose a jackknife for reducing the order of the bias of maximum likelihood estimates of nonlinear dynamic fixed effect panel models in its simplest form the half panel jackknife the estimator is just 2 hat theta bar theta 1 2 where hat theta is the mle from the full panel and bar theta 1 2 is the average of the two half panel mles each using t 2 time periods and all n cross sectional units this estimator eliminates the first order bias of hat theta the order of the bias is further reduced if two partitions of the panel are used for example two half panels and three 1 3 panels and the corresponding mles on further partitioning the panel any order of bias reduction can be achieved the split panel jackknife estimators are asymptotically normal centered at the true value with variance equal to that of the mle under asymptotics where t is allowed to grow slowly with n in analogous fashion the split panel jackknife reduces the bias of the profile likelihood and the bias of marginal effect estimates simulations in fixed effect dynamic discrete choice models with small t show that the split panel jackknife effectively reduces the bias and mean squared error of the mle and yields confidence intervals with much better coverage

current accounts in debtor and creditor countries the authors reexamine a classic question in international economics what is the current account response to a transitory income shock such as a temporary improvement in the terms of trade a transfer from abroad or unusually high production to answer this question they construct a world equilibrium model in which productivity varies across countries and international borrowing and lending take place to exploit good investment opportunities despite its conventional ingredients the model generates the novel prediction that favorable income shocks lead to current account deficits in debtor countries and current account surpluses in creditor countries evidence from thirteen oecd countries broadly supports this theoretical prediction

limits to cba in uk and european environmental policy retrospects and future prospects this paper reviews the contemporary debate and the now long standing role of cba in uk and european environmental policy appraisal epa and looks forward to possible future applications the position taken is that despite its limitations cba still has an important part to play in epa however with the increasingly contested nature of environmental and related public policies and outcomes its role will become less prescriptive and its findings more constrained by social justice and ethical imperatives future cba is more likely to continue to flourish as a component in a wider policy analysis and decision support system whatever decision support system is eventually adopted its value will be judged on how well it aids real policymakers operating iteratively in the non linear real world political economy

borrowing from pui to pay pom multiple borrowing and over indebtedness in rural thailand summary rural financial markets have grown rapidly in asian emerging market economies thus contributing to economic development and the reduction of poverty at the same time however the level of indebtedness of rural households has increased making households more vulnerable to shocks one of the reasons for rising household debt is the ease of borrowing simultaneously from a growing number of lending institutions this paper addresses two major questions first does borrowing from multiple sources increase rural households risk of over indebtedness second do over indebted rural households refinance their outstanding loans through multiple borrowing running the risk of becoming trapped in a debt cycle employing a dynamic random effects bivariate probit model for a unique set of longitudinal household panel data from northeast thailand this study examines the bidirectional relationship between over indebtedness and multiple borrowing to determine to what extent rural households become trapped in debt cycles on the one hand the results indicate that households in northeast thailand take on multiple loans which further increases their risk of becoming over indebted on the other hand our model results do not confirm the widespread notion that over indebted rural households use multiple loans to refinance unpayable debts

consumption and aggregate constraints evidence from u s states and canadian provinces state level consumption exhibits excess sensitivity to lagged income to the same extent as u s aggregate data but state specific idiosyncratic consumption exhibits substantially less sensitivity to lagged state specific income a result that also holds for canadian provinces we propose the following interpretation borrowing and lending in response to changes in consumer demand are easier for individual u s states than for the united states as a whole and therefore the measured deviation from the benchmark permanent income hypothesis model is smaller however lagged state specific variables help predict state specific consumption suggesting that the pih model still requires qualification

regional capital flows and economic regimes evidence from china abstract using provincial data from china this paper examines the pattern of capital flows in relation to the transition of economic regimes we show that fast growing provinces experienced less capital inflows before the large scale market reform contrary to the prediction of the neoclassical growth theory as china transitioned from the central planning economy to the market economy the negative correlation between productivity growth and capital inflows became much less pronounced from a regional perspective this finding suggests domestic institutional factors play an important role in shaping the pattern of capital flows

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

a framework for estimating dynamic unobserved effects panel data models with possible feedback to future explanatory variables abstract i show how to construct the likelihood function for the conditional maximum likelihood estimator in dynamic unobserved effects models where not all conditioning variables are strictly exogenous the method for handling the initial conditions problem appears to be novel and offers a flexible relatively simple alternative to existing methods

why doesn t capital flow from rich to poor countries an empirical investigation we examine the empirical role of difierent explanations for the lack of ows of capital from rich to poor countries the lucas paradox the theoretical explanations include difierences in fundamentals across countries and capital market imperfections we show that during 1970i2000 low institutional quality is the leading explanation for example improving peru s institutional quality to australia s level implies a quadrupling of foreign investment recent studies emphasize the role of institutions for achieving higher levels of income but remain silent on the speciflc mechanisms our results indicate that foreign investment might be a channel through which institutions afiect long run development

why does capital flow to rich states abstract the magnitude and the direction of net international capital flows do not fit neoclassical models the fifty u s states comprise an integrated capital market with very low barriers to cap

are bilateral remittances countercyclical by putting together a relatively large data set on bilateral remittances of emigrants this paper is able to shed light on the important hypothesis of smoothing the smoothing hypothesis is that remittances are countercyclical with respect to income in the worker s country of origin the recipient of the remittance while procyclical with respect to income in the migrant s host country the sender of the remittance the econometric results confirm the hypothesis this affirmation of smoothing is important for two reasons first it suggests that remittances should be placed on the list of criteria for an optimum currency area second it brings into doubt plans by governments in some developing countries to harness remittances for their own use in that government spending in these countries generally fails the test of countercyclicality which remittances pass

a structural model of the retail market for illicit drugs we estimate a model of illicit drugs markets using data on purchases of crack cocaine buyers are searching for high quality drugs but they determine drugs quality i e their purity only after consuming them hence sellers can rip off first time buyers or can offer higher quality drugs to induce buyers to purchase from them again in equilibrium a distribution of qualities persists the estimated model implies that if drugs were legalized in which case purity could be regulated and hence observable the average purity of drugs would increase by approximately 20 percent and the dispersion would decrease by approximately 80 percent moreover increasing penalties may raise the purity and affordability of the drugs traded by increasing sellers relative profitability of targeting loyal buyers versus first time buyers

environmental regulation and foreign direct investment evidence from south korea abstract this paper studies how environmental regulation shapes the pattern of foreign direct investment fdi and thereby assesses the pollution haven hypothesis conflicting results exist in the case studies examining the most advanced countries partly due to the deterrent effect of clean technology adoptions on industry migration to minimize the clean technology effect we examine the pattern of south korean fdi over 2000 2007 the period that korean firms relied on old production technologies despite facing rapidly strengthened environmental standards a difference in differences type identification strategy circumvents other potential confounders we find strong evidence that polluting industries tend to invest more in countries with laxer environmental regulations in terms of both the amount of investment intensive margin and the number of new foreign affiliates extensive margin a similar finding is obtained when imports are analyzed

crossing the innovation threshold through mergers and acquisitions firms are resorting more and more to mergers and acquisitions m a to bridge the gap between where they are and where they would like to be in relation to innovation and performance this paper investigates whether involvement in m a triggers distinct patterns of innovative behaviour across firms and whether this effect is conditional on firm size the analysis combines data from four waves of the community innovation survey cis and the business register of dutch manufacturing firms we observe that m as influence the probability that firms will begin innovation activities or persist with them and these effects vary at different points in the firm size distribution in particular by using m a firms are able to persist with the innovation efforts and output over time and this effect is especially strong for large firms for small firms m a help them to cross the innovation threshold increasing the probability of the transition from a non innovator to an active innovator however the m a effect does not mitigate the tendency of small firms to be occasional innovators
