is social capital green cultural features and environmental performance in the european union this paper analyses the relationship between social capital and environmental performance in the european union in a first stage environmental performance is measured by an index of eco efficiency at the country level computed using data envelopment analysis techniques and data for the year 2013 in a second stage the influence of social capital and other relevant control variables on eco efficiency is assessed by means of truncated regressions and bootstrapping as proposed by simar and wilson j econom 136 1 31 64 2007 for several model specifications tests fail to reject the hypothesis of no effect of social capital on environmental performance and the main driver of environmental performance is found to be the level of economic development measured by gdp per capita furthermore this result is robust to different definitions of social capital and sample periods

the power of green defaults the impact of regional variation of opt out tariffs on green energy demand in germany abstract the present paper focuses on green defaults as demand side policies supporting the uptake of renewable energy in germany it sets out to gain a better understanding of whether and for whom green electricity defaults work the present study is one of the first to use a large scale data set to investigate this question we combine micro level data from the german socio economic panel gsoep covering private households including a wealth of individual information with macro level information such as population density of a region and proportion of energy suppliers in a given region that use a green opt out tariff within their basic supply we show that in germany green defaults automatically enrolling customers in renewable energy sources tend to stick especially but not only among those who are concerned about the problem of climate change this finding based on real world rather than experimental evidence attests to the power of automatic enrollment in addressing environmental problems in germany and potentially beyond including climate change and also adds to the growing literature on the substantial effects of shifting from opt in to opt out strategies

clean up your own mess an experimental study of moral responsibility and efficiency although market based environmental policy instruments feature prominently in economic theory and are widely employed they often face public resistance we argue that such resistance may be driven by moral responsibility where citizens prefer to tackle the environmental problems that they have caused by themselves rather than delegating the task to others by means of a market mechanism using a laboratory experiment that isolates moral responsibility from alternative explanations we show that moral responsibility induces participants to take inefficient actions that reduce the earnings of the whole group of participants we discuss the implications of this finding for the design and implementation of environmental policies

reacting to rankings evidence from america s best hospitals rankings and report cards have become a popular way of providing information in a variety of domains i estimate the response to rankings in the hospital market and find that hospitals that improve their rank are able to attract significantly more patients the average hospital in my sample experiences a 5 change in non emergency medicare patient volume from year to year due to rank changes these findings have implications regarding the competitiveness of hospital markets and the effect that the dissemination of quality information in hospital markets can have on individual choice

measuring welfare from ambulatory surgery centers a spatial analysis of demand for healthcare facilities this paper studies competition between healthcare facilities particularly between hospitals and ambulatory surgery centers asc s in the market for outpatient surgery the goal is to answer questions about the existence and magnitude of welfare gains earned from the use of asc s these questions are relevant to current policy debates about the usefulness of asc s i calculate welfare by specifying a multinomial logit model of consumer demand for healthcare facilities and estimating structural elements of demand functions total elimination of asc s results in between 10 2 and 28 1 minutes of welfare loss per patient surgery

what went wrong the erosion of relative earnings and employment among young black men in the 1980s this paper shows a widening in black white earnings and employment gaps among young men from the mid 1970s through the 1980s earnings gaps increased most among college graduates and in the midwest while gaps in employment population rates grew most among dropouts we attribute the differential widening to shifts in demand for subgroups due to shifting industry and regional employment the falling real minimum wage and deunionization the growing supply of black to white workers that was marked among college graduates and to increased crime among dropouts the different factors affecting subgroups highlight the economic diversity of black americans

organized labor and racial wage inequality in the united states why have african american private sector unionization rates surpassed those of white workers for decades and how has private sector union decline exacerbated black white wage inequality using data from the current population survey 1973 2007 the authors show that african americans join unions for protection against discriminatory treatment in nonunion sectors a model predicted wage series also shows that among women black white weekly wage gaps would be between 13 and 30 lower if union representation remained at high levels the effect of deunionization on racial wage inequality for men is less substantial but without deunionization weekly wages for black men would be an estimated 49 higher the results recast organized labor as an institution vital for its economic inclusion of african american men and women this study points to the need to move beyond class based analyses of union decline to an understanding of the gendered role unions once played in mitigating racial inequality

the rise of intra occupational wage inequality in the united states 1983 to 2002 wage inequality has increased dramatically in the united states since the 1980s this article investigates the relationship between this trend and occupational structure measured at the three digit level using the current population survey from 1983 to 2002 we find that the direct association between occupations and wage inequality declined over this period as within occupational inequality grew faster than betweenoccupational inequality we estimate multilevel growth models using detailed occupational categories as the unit of analysis to assess how the characteristics of occupations affect changes in mean wages and levels of wage inequality across this time period the results indicate that changes in mean wages across occupations vary depending on the characteristics of individuals in those occupations and that intraoccupational inequality is difficult to predict using conventional labor force data these findings seem largely inconsistent with the common sociological view of occupation as the most fundamental feature of the labor market correspondingly a more comprehensive approach one that incorporates the effects of organizational variables and market processes on rising wage inequality in the new economy is warranted

quality competition with profit constraints abstract firms in markets such as health care and education are often profit constrained due to regulation or their non profit status and they are often viewed as being altruistic towards consumers we use a spatial competition framework to study incentives for cost containment and quality provision by altruistic firms facing profit constraints if prices are regulated profit constraints lead to lower cost containment efforts but higher quality if and only if firms are sufficiently altruistic under price competition profit constraints reduce quality and cost containment efforts but lead to lower prices if and only if firms are sufficiently altruistic profit constrained firms cost containment efforts are below the first best while their quality might be too high or too low if prices are regulated profit constraints can improve welfare and be a complement or substitute to a higher regulated price depending on the degree of altruism

the effect of entry regulation in the health care sector the case of home health the consequences of government regulation in the post acute care sector are not well understood we examine the effect of entry regulation on quality of care in home health care by analyzing the universe of hospital discharges during 2006 for publicly insured beneficiaries about 4 5 million and subsequent home health admissions to determine whether there is a significant difference in home health utilization hospital readmission rates and health care expenditures in states with and without certificate of need laws con regulating entry we identify these effects by looking across regulated and nonregulated states within hospital referral regions which characterize well defined health care markets and frequently cross state boundaries we find that con states use home health less frequently but system wide rehospitalization rates overall medicare expenditures and home health practice patterns are similar removing con for home health would have negligible system wide effects on health care costs and quality

the short run and long run effects of behavioral interventions experimental evidence from energy conservation we document three remarkable features of the opower program in which social comparison based home energy reports are repeatedly mailed to more than six million households nationwide first initial reports cause high frequency action and backsliding but these cycles attenuate over time second if reports are discontinued after two years effects are relatively persistent decaying at 10 20 percent per year third consumers are slow to habituate they continue to respond to repeated treatment even after two years we show that the previous conservative assumptions about post intervention persistence had dramatically understated cost effectiveness and illustrate how empirical estimates can optimize program design jel d12 d83 l94 q41

behavioral innovations the missing capital in sustainable development abstract many scholars argue that environmental issues can be addressed through technological innovation a proposal which echoes a lasting debate between environmental and ecological economics about the substitution rate between natural and manufactured capital in addition to these two established types of capital this paper introduces the idea of behavioral capital we define behavioral capital as the latent potential of behavioral change to affect improvement in environmental quality our contribution argues that technological and traditional regulatory innovations serve as insufficient tools for addressing modern environmental issues and ensuring sustainable development without discarding these solutions we contend that because human behavior is a significant contributor to environmental problems it should be regarded as a key component of continued solutions we suggest that the dual interest theory can serve as an integrative framework for behavioral innovations related to environmental issues in suggesting this we assume that behavioral innovations can both overcome some of the limitations of technological innovations and offer new solutions our main insight is to suggest that some depletion of natural capital but not all can be offset by behavioral changes without decreasing or even increasing subjective well being

social norms and pro environmental behavior a review of the evidence in light of the growing attention that social norm interventions have garnered as policy tools we review the current body of evidence on their effectiveness with respect to pro environmental behaviors we identify the various conceptualizations of social norms currently in use and inventory the experimental economics and social psychology literature that has examined the impacts of social norm interventions on pro environmental behavior for each study included in this inventory we note several contextual features the data collection and analytical methods used and any significant main effects attributed to the social norm intervention we also review several theoretical models of behavior that incorporate social norms based on this empirical and theoretical review we draw a number of policy implications and identify avenues for future research on the role of social norms with respect to pro environmental behavior

competition among hospitals we examine competition in the hospital industry in particular the effect of ownership type for profit not for profit government we estimate a structural model of demand and pricing in the hospital industry in california then use the estimates to simulate the effect of a merger california hospitals in 1995 face an average price elasticity of demand of 4 85 not for profit hospitals face less elastic demand and act as if they have lower marginal costs their prices are lower than those of for profits but markups are higher we simulate the effects of the 1997 merger of two hospital chains in san luis obispo county where the merger creates a near monopoly prices rise by up to 53 and the predicted price increase would not be substantially smaller were the chains not for profit

black white wage inequality employment rates and incarceration the observed gap in average wages between black men and white men inadequately reflects the relative economic standing of blacks who suffer from a high rate of joblessness the authors estimate the black white gap in hourly wages from 1980 to 1999 adjusting for the sample selection effect of labor inactivity among working age men in 1999 accounting for labor inactivity including prison and jail incarceration leads to an increase of 7 20 in the black white wage gap adjusting for sample selectivity among men ages 22 30 in 1999 increases the wage gap by as much as 58 increasing selection bias which can be attributed to incarceration and conventional joblessness explains about two thirds of the rise in black relative wages among young men between 1985 and 1998 apparent improvement in the economic position of young black men is thus largely an artifact of rising joblessness fueled by the growth in incarceration during the 1990s

applied welfare economics with discrete choice models economists have been paying increasing attention to the study of situations in which consumers face a discrete rather than a continuous set of choices such models are potentially very important in evaluating the impact of government programs upon consumer welfare but very little has been said in general regarding the tools of applied welfare economics indiscrete choice situations this paper shows how the conventional methods of applied welfare economics can be modified to handle such cases it focuses on the computation of the excess burden of taxation and the evaluation of quality change the results are applied to stochastic utility models including the popular cases of probit and logit analysis throughout the emphasis is on providing rigorous guidelines for carrying out applied work this abstract was borrowed from another version of this item

patient mobility and health care quality when regions and patients differ in income we study the effects of cross border patient mobility on health care quality and welfare when income varies across and within regions we use a salop model with a high middle and low income region in each region a policy maker chooses health care quality to maximise the utility of its residents when health care costs are financed by general income taxation in equilibrium regions with higher income offer better quality which creates an incentive for patient mobility from lower to higher income regions assuming a prospective payment scheme based on drg pricing we find that lower non monetary administrative mobility costs have i no effect on quality or welfare in the high income region ii a negative effect on quality but a positive effect on welfare for the middle income region and iii ambiguous effects on quality and welfare for the low income region lower monetary mobility costs copayments might reduce welfare in both the middle and low income region thus health policies that stimulate cross border patient mobility can be counterproductive when regions differ in income

constructing labor markets the valuation of black labor in the u s south 1831 to 1867 in the u s south a free labor market rapidly although in some cases only nominally replaced the plantation system of slave labor in the years following the american civil war drawing on data comprising 75 099 transactions in the antebellum period as well as 1 378 labor contracts in the postbellum era i examine how the valuation of black labor was transformed between the 1830s and the years of emancipation i trace the process of valuation through four markets for labor moving from slave purchases and appraisals within the plantation economy to the antebellum system of hiring out to wage setting for black labor under the auspices of the freedmen s bureau comparative analysis of labor pricing across these markets reveals systematic differences slave markets placed price premiums on children and young women and occupational skills emerged as the most salient influence in the pricing of wage labor i conclude by theorizing how transvaluation of labor occurs when markets for unfree and free worker

the industrial organization of health care markets the u s health care sector is large and growing health care spending in 2011 amounted to 2 7 trillion and 18 percent of gdp approximately half of health care output is allocated via markets in this paper we analyze the industrial organization literature on health care markets focusing on the impact of competition on price quality and treatment decisions for health care providers and health insurers we conclude with a discussion of research opportunities for industrial organization economists including opportunities created by the u s patient protection and affordable care act

the price ain t right hospital prices and health spending on the privately insured we use insurance claims data for 27 6 percent of individuals with private employer sponsored insurance in the us between 2007 and 2011 to examine the variation in health spending and in hospitals transaction prices we document the variation in hospital prices within and across geographic areas examine how hospital prices influence the variation in health spending on the privately insured and analyze the factors associated with hospital price variation four key findings emerge first health care spending per privately insured beneficiary varies by a factor of three across the 306 hospital referral regions hrrs in the us moreover the correlation between total spending per privately insured beneficiary and total spending per medicare beneficiary across hrrs is only 0 14 second variation in providers transaction prices across hrrs is the primary driver of spending variation for the privately insured whereas variation in the quantity of care provided across hrrs is the primary driver of medicare spending variation consequently extrapolating lessons on health spending from medicare to the privately insured must be done with caution third we document large dispersion in overall inpatient hospital prices and in prices for seven relatively homogenous procedures for example hospital prices for lower limb mris vary by a factor of twelve across the nation and on average two fold within hrrs finally hospital prices are positively associated with indicators of hospital market power even after conditioning on many demand and cost factors hospital prices in monopoly markets are 15 3 percent higher than those in markets with four or more hospitals

social influence and collective action effects on farm level soil conservation effort in rural kenya abstract this paper analyzes the effects of social influence and participation in collective action initiatives on soil conservation effort among smallholder farmers in lake naivasha basin kenya we apply binary and ordered probit models in a two stage regression procedure to cross sectional data collected through a household survey among randomly selected smallholder farmers smallholder farming systems in the research area are associated with practices that render farmlands susceptible to soil erosion causing negative impacts on land and the environment therefore strategies that encourage soil conservation are likely to also offer solutions for dealing with agri environmental challenges and poverty alleviation results indicate that social capital facilitates participation in collective action initiatives which then influence individual soil conservation efforts neighborhood social influences subjective norms gender education level farm size access to credit and livestock ownership also emerge as key determinants of soil conservation effort policy implications drawn by this study encourage strategies to increase participation and effectiveness in collective action initiatives as a boost to soil conservation implementation of soil conservation practices could also be encouraged through awareness increasing instruments facilitating access to agricultural micro credit and paying attention to gender related challenges on knowledge access and rights over land and other natural resources

an experimental test of the effect of negative social norms on energy efficient investments abstract energy efficiency is an important economic and environmental concern and likewise the correction of current wasteful energy practices we document widespread tire pressure neglect three quarters of drivers waste gas driving on underinflated tires negative descriptive social norms are one potential cause but have not been tested in high neglect environments where those norms are widespread this confounds the mechanism are these norms signals of private value to consumers or do they imply standards for social judgment from others we conducted a field experiment at gas stations in chicago our intervention included treatments with information about tire pressure neglect promotions in the form of price reductions from 0 50 to free a descriptive norm of behavior and help in the form of air pump assistance the treatments are designed to provide the ability to consider four potential underlying drivers information monetary cost social norms and social pressure treatments that only included information were ineffective despite average fuel savings of 10 51 but small promotions had substantial impacts when the air pump price was free the social norm discouraged inflation however when the research assistant offered help inflation rates were buoyed by the social norm these results highlight the importance of incentives over mere information treatments and offer a new perspective on how information and monetary levers can influence decision making in the presence of negative social norms

delivered pricing and the impact of spatial differentiation on cartel stability abstract this paper analyzes the impact of spatial differentiation on the sustainability of collusion on delivered prices it shows that the choice of the punishment mechanism that enforces collusion is crucial for determining whether differentiation facilitates cartel pricing or not if punishments are optimal then differentiation tends to facilitate collusion optimal punishments impose minmax profits on deviators independently of the degree of differentiation a high degree of differentiation then renders deviations less profitable since it makes business stealing more costly but does not affect the deviator s punishment profits depending on the transport cost technology excessive differentiation may have a countervailing effect however because it also implies high transport costs for the cartel if collusion is sustained by standard grim trigger punishments instead then collusion may be easiest for minimal differentiation the reason is that competitive and thus grim trigger punishment profits are higher the higher the degree of differentiation

the welfare effects of restricted hospital choice in the us medical care market summary managed care health insurers in the usa restrict their enrollees choice of hospitals to within specific networks this paper considers the implications of these restrictions a three step econometric model is used to predict consumer preferences over health plans conditional on the hospitals they offer the results indicate that consumers place a positive and significant weight on their expected utility from the hospital network when choosing plans a welfare analysis assuming fixed prices implies that restricting consumers choice of hospitals leads to a loss to society of approximately 1 billion per year across the 43 us markets considered this figure may be outweighed by the price reductions generated by the restriction copyright 2006 john wiley sons ltd

estimation and identification of merger effects an application to hospital mergers abstract existing empirical estimates of merger effects are compromised by the fact that merging and nonmerging entities differ in unobserved ways that independently affect outcomes of interest to obtain an unbiased estimate of the effect of consummated mergers i propose an approach that focuses on the response of rivals to mergers and accounts for the endogeneity of exposure to these mergers i apply this approach to evaluate the impact of independent hospital mergers in the united states between 1989 and 1996 using the physical colocation of rivals as an instrument for whether they merge i find a sizeable one time increase in price following a rival s merger with the greatest increase occurring among hospitals nearest the merging hospitals these results are more consistent with predictions from structural models of the hospital industry than with prior observational estimates of the effects of hospital mergers

valuing new goods in a model with complementarity online newspapers many important economic questions hinge on the extent to which new goods either crowd out or complement consumption of existing products recent methods for studying new goods rule out complementarity by assumption so their applicability to these questions has been limited i develop a new model that relaxes this restriction and use it to study competition between print and online newspapers using new micro data from washington dc i estimate the relationship between the print and online papers in demand the welfare impact of the online paper s introduction and the expected impact of charging positive online prices

a dynamic model of quality competition with endogenous prices abstract we develop a dynamic model of price and quality competition in order to analyze the effects of competition on quality provision and to which extent an unregulated market is able to provide a socially optimal quality level our model combines a differential game approach with a hotelling spatial competition framework and our analysis applies in particular to industries such as long term care health care child care and education if providers nursing homes hospitals schools nurseries use closed loop decision rules which imply strategic interaction over time we show that although increased competition leads to higher quality in the steady state quality provision is nevertheless lower than under open loop rules and also suboptimally low from a welfare perspective thus our analysis identifies dynamic strategic interaction between competing providers as a potential source of inefficiency in quality provision

inequality neighbourhoods and welfare of the poor abstract this paper investigates how neighbourhood effects interacting with income inequality affect poor people s ability to access basic facilities like health care services schooling and so on we model this interaction by integrating consumers income distribution with the spatial distribution of their location and explore the consequences of an increase in income inequality or variations in the neighbourhood characteristics on the welfare of the rich and poor in general and their access to market in particular we find that in general the impact will be non monotonic owing to an interesting trade off between the provision effect and the price effect on the one hand there is the positive provision effect higher valuation of the rich attracts the supplier to enter into the neighbourhood allowing the poor who live sufficiently close by to access the service on the other hand there is the negative price effect the service provider charges a higher price higher is the income or larger is the proportion of the rich in the neighbourhood in the extreme there exists the possibility of complete exclusion of poor from the market the service provider caters only to the rich and the poor has absolutely no market access we have identified the higher income gap between rich and poor as the key factor that exposes the poor to this complete exclusion possibility

assessing competition in hospital care markets the importance of accounting for quality differentiation quality differentiation is especially important in the hospital industry where the choices of medicare patients are unaffected by prices unlike previous studies that use geographic market concentration to estimate hospital competitiveness this article emphasizes the importance of quality differentiation in this spatially differentiated market i estimate a random coefficients discrete choice model that predicts patient flow to different hospitals and find that demand responses to both distance and quality are substantial the estimates suggest that patients do not substitute toward alternative hospitals in proportion to current market shares implying that geographic market concentration is an inappropriate measure of hospital competitiveness

racial wage inequality job segregation and devaluation across u s labor markets1 despite decades of research showing greater black white inequality in local areas where the black population is relatively large little is known about the mechanisms for this effect using a unique data set of individuals nested within jobs across labor markets this article tests two possible mechanisms for the black concentration effect on wage inequality job segregation and devaluation results show that black population size is associated with greater segregation of black workers into black dominated jobs on the other hand no evidence is found that the penalty for working in a black dominated job the devaluation effect increases as a function of black population size the article concludes that discrimination against workers especially exclusion from better paying jobs is an important mechanism for the effect of black population size on the racial wage gap

economic change and rising income inequality in the oslo region the importance of knowledge intensive business services wessel t economic change and rising income inequality in the oslo region the importance of knowledge intensive business services regional studies the growth of market income inequality in the oslo region of norway between 1993 and 2004 is investigated using two measures it is shown that most of the change occurred within knowledge intensive business services and further within demographic subgroups changes in mean income between group inequality and shifts in the balance between segments of the economy are of minor importance the results support a combined focus on productive paths and institutions labour relations in particular appear as an important explanation however labour relations can hardly explain why men rather than women and western immigrants rather than non western immigrants converge towards employment in high profit businesses this particular pattern requires research beyond the economic and institutional landscape wessel t

long run trends in workers beliefs about their own job security evidence from the general social survey in recent years federal reserve chairman alan greenspan former u s secretary of labor robert reich and many journalists have argued that workers are more anxious about losing their jobs than they were in the past i use the 1977 96 general social survey to document trends in workers beliefs about their own job security during the 1990s workers have been more pessimistic about losing their jobs in the next 12 months than workers were during the 1980s workers have also been more concerned about suffering future job loss that would have resulted in a decline in earnings or a spell of unemployment

prices information and nudges for residential electricity conservation a meta analysis incentivising households to lower their electricity consumption is increasingly used as a tool to create a more flexible electricity demand previous reviews estimate that electricity savings of 6 4 7 4 can be achieved through monetary informational and behavioural incentives this papers argues that a more realistic estimate is of a 1 9 3 9 reduction in consumption based on the most recent experimental data from both peer reviewed and grey literature sources using data from 52 studies published during the smart grid era 2005 onwards the effects of incentives from 128 observations amounting to 713 002 households are analysed the results show that individual and real time feedback as well as personalised advice on how to save electricity are more effective than feedback on electricity costs and general electricity savings tips which lead to relative increases in consumption despite improvements in the quality of more recent studies the analysis highlights the importance of methodological rigour in carrying out and reporting effects of incentives an absence of a control group of socio demographic data and the self selection of participants into treatment leads to overestimation of effects

economics and identity this paper considers how identity a person s sense of self affects economic outcomes we incorporate the psychology and sociology of identity into an economic model of behavior in the utility function we propose identity is associated with different social categories and how people in these categories should behave we then construct a simple game theoretic model showing how identity can affect individual interactions the paper adapts these models to gender discrimination in the workplace the economics of poverty and social exclusion and the household division of labor in each case the inclusion of identity substantively changes conclusions of previous economic analysis

competition and waiting times in hospital markets this paper studies the impact of hospital competition on waiting times we use a salop type model with hospitals that differ in geographical locationand potentially waitingtime andtwotypesofpatients high benefitpatientswhochoosebetweenneighbouring hospitals competitive segment and low benefit patients who decide whether or not to demand treatment from the closest hospital monopoly segment compared with a benchmark case of monopoly we find that hospital competition leads to longer waiting times in equilibrium if the competitive segment is sufficiently large given a policy regime of hospital competition the effect of increased competition depends on the parameter of measurement lower travelling costs increase waiting times higher hospital density reduces waiting times while the effect of a larger competitive segment is ambiguous we also show that if the competitive segment is large hospital competition is socially preferable to monopoly only if the regulated treatment price is sufficiently high 2008 elsevier b v all rights reserved

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

hospital competition in hmo networks abstract we develop a framework for analyzing bargaining relationships between hospitals and hmos under selective contracting using a unique dataset on hospitals in the los angeles area from 1990 to 1993 we estimate the determinants of actual negotiated prices paid to hospitals by two major hmos we find that a hospital s bargaining power and thus its price decrease when the hmo can readily turn to alternative networks that exclude the hospital we simulate the effect of hypothetical hospital mergers on bargaining power and find that some hospital mergers even in urban areas with many nearby hospitals can lead to significant price increases

exit from the hospital industry we study the exit of hospitals from the market for inpatient services more generous hospital reimbursement significantly reduces the probability of exit throughout the 1990s conditional on reimbursement levels hospital efficiency was not a significant determinant in the early 1990s but in the mid to late 1990s less efficient hospitals were significantly more likely to exit throughout the period high tech services increased the probability of survival and for profit hospitals were more likely to exit the role of medicare as a determinant of exit became less important in the latter half of the 1990s

no man is an island social coordination and the environment humans are fundamentally social social activities require coordination possibly leading to multiple equilibria in the form of self reinforcing patterns of herd behavior when alternative equilibria differ substantially with respect to environmental damage they represent virtuous and vicious cycles from an environmental perspective such cycles can be sustained by network effects social pressure to conform or other mechanisms directly or indirectly yielding coordination benefits breaking the vicious cycles can be an important task for environmental policies i present a stylized model of social coordination with environmental externalities using it to discuss how environmental policies may help agents coordinate in more environment friendly ways

profit variability in for profit and not for profit hospitals this paper proposes two tests of the hypothesis that not for profit hospitals nfps behave differently than for profit hospitals the profit variability test states that the profits of an nfp will be less variable over time than profits of a for profit hospital if the nfp maximizes utility subject to a profit constraint the second test examines whether nfp profits respond less to change in exogenous factors such as medicare reimbursement rates than profits of for profit hospitals both tests performed on panel data from 1983 to 1988 support the hypothesis that nfps behave differently than for profit hospitals

the effect of reimbursement on the intensity of hospital services we examine how hospital treatment intensity is affected by an exogenous change in average reimbursement for an admission theory predicts that treatment intensity would be most affected for highly profitable services but unaffected for unprofitable services we use medicare inpatient data from 11 states for 16 disease categories that vary in the generosity of reimbursement to test this prediction using the coefficients from quantile regressions we calculate a difference in difference estimate of the effect of the balanced budget act bba of 1998 comparing the pre and post bba change in treatment intensity at high medicare share hospitals to low medicare share hospitals we find that not for profit hospitals cut treatment intensity at the 50th 75th and 95th quantiles only for generously reimbursed services intensity at the 25th percentile was unaffected regardless of generosity we did not measure a statistically significant response at for profit or public hospitals to the bba

recreation demand models with taste differences over people we estimate random parameter logit models of anglers choice of fishing site the models generalize logit by allowing coefficients to vary randomly over anglers rather than being fixed the models do not exhibit the restrictive independence from irrelevant alternatives property of logit and can represent any substitution pattern estimation explicitly accounts for the fact that the variation in coefficients over anglers induces correlation in unobserved utility over trips by the same angler willingness to pay for improved fish stock and the value to anglers of specific sites are calculated from the models and compared with the estimates obtained from a standard logit model

public praise vs private pay effects of rewards on energy conservation in the workplace any solution to rising levels of co2 depends on human behavior one common approach to changing human behavior is rewarding desired behavior because financial incentives often have side effects that diminish efficacy we predict that social rewards are more effective because they invoke adherence to descriptive and injunctive social norms we investigated this by measuring electricity use for 13 weeks at a dutch firm each week employees were rewarded for conserving energy they either received monetary rewards 0 5 or social rewards grade points with a descriptive comment rewards were either private or public in both the short and long term public rewards outperformed private rewards and social rewards outperformed monetary rewards this suggests that private monetary rewards although popular may be ineffective instead public social rewards may be a more promising approach to stimulating energy conservation we argue that this approach should be considered more frequently by policy makers

free to choose reform choice and consideration sets in the english national health service choice in public services is controversial we exploit a reform in the english national health service to assess the effect of removing constraints on patient choice we estimate a demand model that explicitly captures the removal of the choice constraints imposed on patients we find that post removal patients became more responsive to clinical quality this led to a modest reduction in mortality and a substantial increase in patient welfare the elasticity of demand faced by hospitals increased substantially post reform and we find evidence that hospitals responded to the enhanced incentives by improving quality this suggests greater choice can raise quality

explaining the black white gap in labor force participation among women heading households for the first time in this century black women are participating in the labor force at lower rates than are white women the black white gap in female labor force participation is driven by those in the severest need of income women heading households the author compares three explanations of the black white gap in labor force participation among female household heads lack of human capital lack of opportunities resulting from industrial restructuring and disarticulation from mainstream institutions as described by theories of the underclass using a representative national sample from the panel study of income dynamics he finds that lower rates of labor force participation among black women heading households are determined by black white differences in human capital as well as by characteristics associated with a breakdown in the processes linking black women to the labor market overall the largest impediments to labor force participation among women heading households are dropping out of high school having a child under the age of six in the household and being a long term welfare recipient

sources of racial wage inequality in metropolitan labor markets racial ethnic and gender differences research on racial inequality has become increasingly specialized often focusing on a single explanation and subgroup of the population in a diverse society a broader comparative framework for interpreting the causes of wage inequality for different racial ethnic and gender groups is called for the effects of a range of different factors on the wages of latinos asians and blacks relative to whites and separately for women and men are examined new sources of racial wage inequality are also considered significant differences are found in the sources of wage inequality across race ethnicity and gender differences are generally greater between racial and ethnic groups than between men and women key findings include a large negative effect of immigration on the relative wages of latinos and asians and only a small effect on the relative wages of black women and no effect on black men in contrast the relative wages of blacks remain most affected positively by the presence of manufacturing employment and unions new economy indicators of high skill services and flexible employment conditions play only a secondary role in explaining metropolitan racial wage inequality

energy conservation nudges and environmentalist ideology evidence from a randomized residential electricity field experiment nudges are being widely promoted to encourage energy conservation we show that while the electricity conservation nudge of providing feedback to households on own and peers home electricity usage works with liberals it can backfire with conservatives our regression estimates predict that a democratic household that pays for electricity from renewable sources that donates to environmental groups and that lives in a liberal neighborhood reduces its consumption by 3 percent in response to this nudge a republican household that does not pay for electricity from renewable sources and that does not donate to environmental groups increases its consumption by 1 percent
