credit constraints and the phenomenon of child labor abstract this paper develops an overlapping generations general equilibrium model where inefficient child labor arises due to credit constraints it derives a positive relationship between inequality in the distribution of income and the incidence of child labor looking at policy implications it shows how trade sanctions against countries using child labor may fail to reduce the incidence of child labor it discusses some alternative policies to reduce the incidence of child labor

quality competition with motivated providers and sluggish demand we study incentives for quality provision in markets where providers are motivated semi altruistic prices are regulated and firms are funded by a combination of block grants and unit prices competition is based on quality and demand adjusts sluggishly health or education are sectors in which the mentioned features are the rule we show that the presence of motivated providers makes dynamic competition tougher resulting in higher steady state levels of quality in the closed loop solution than in the benchmark open loop solution if the price is sufficiently high however this result is reversed if the price is sufficiently low and below unit costs sufficiently low prices also imply that a reduction in demand sluggishness will lead to lower steady state quality prices below unit costs will nevertheless be welfare optimal if the providers are sufficiently motivated

consumer trust social marketing and ethics of welfare exchange the global corporate scandals such as enron worldcom and global crossing have raised fundamental issues of business ethics as well as economic social and anthropological questions concerning the nature of business competition and global capitalism the purpose of this conceptual paper is to introduce the concept of welfare exchange to the existing notions of economic social and anthropological notions of business and exchange in markets and society in the 21st century global competition and business success in the 21st century continue to raise the nature of economic value and the interaction among diverse actors in international markets institutions and society we believe that the nature of such exchange between consumers and organizations which can also be termed social marketing need to increasingly take into account a welfare and ethical component in this paper we introduce our concept of welfare exchange to emphasize the importance of such welfare and ethical issues in the global business environment of the 21st century

price adjustment in the hospital sector we analyse the properties of optimal price adjustment to hospitals when no lump sum transfers are allowed and when prices differ to reflect observable exogenous differences in costs we find that a when the marginal benefit from treatment is decreasing and the cost function is the power function price adjustment for hospitals with higher costs is positive but partial if the marginal benefit is constant the price is identical across providers b if the cost function is exponential or it is separable in monetary and non monetary costs and linear in monetary costs price adjustment is positive even when the marginal benefit is constant c higher inequality aversion of the purchaser increases concentration in prices and lowers concentration in quantities d if some dimensions of costs are private information a higher correlation between the observable and unobservable cost component increases the optimal price for providers whose observable costs are above the average

what will consumers pay for social product features the importance of ethical consumerism to many companies worldwide has increased dramatically in recent years ethical consumerism encompasses the importance of non traditional and social components of a company s products and business process to strategic success such as environmental protectionism child labor practices and so on the present paper utilizes a random utility theoretic experimental design to provide estimates of the relative value selected consumers place on the social features of products

hospital competition with soft budgets we study the incentives for hospitals to provide quality and expend cost reducing effort when their budgets are soft i e the payer may cover deficits or confiscate surpluses the basic set up is a hotelling model with two hospitals that differ in location and face demand uncertainty where the hospitals run deficits surpluses in the high low demand state softer budgets reduce cost efficiency while the effect on quality is ambiguous for given cost efficiency softer budgets increase quality since parts of the expenditures may be covered by the payer however softer budgets reduce cost reducing effort and the profit margin which in turn weakens quality incentives we also find that profit confiscation reduces quality and cost reducing effort first best is achieved by a strict no bailout and no profit confiscation policy when the regulated price is optimally set however for suboptimal prices a more lenient bailout policy can be welfare improving

the effects of hospitals governance on optimal contracts bargaining vs contracting we propose a two stage model to study the impact of different hospitals governance frameworks on the optimal contracts designed by third party payers when patients disease severity is the private information of the hospital in the second stage doctors and managers interact within either a bargaining or a contracting scenario in the contracting scenario managers offer a contract that determines the payment to doctors and doctors decide how many patients to treat in the bargaining scenario doctors and managers strategically negotiate on both the payment to doctors and the number of patients to treat we derive the equilibrium doctors payments and number of treated patients under both scenarios we then derive the optimal contract offered by the government to the hospital in the first stage results show that when the cost of capital is sufficiently low the informational rent is lower and the social welfare is higher in the contracting scenario

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

testing the external effect of household behavior the case of the demand for children this paper tests the external effect of household childbearing behavior by drawing on microfertility data from china the test is executed by regressing one woman s fertility on the average fertility of neighboring women china s unique affirmative birth control policy provides us with quasi experimental fertility variation that facilities identification we present two identification methods 1 testing the external effect from the dominant han chinese on minority women by using the fertility fine as an instrumental variable and 2 identifying the external effect using an instrumental variable that is based on the difference in differences we find that fertility has a large external effect

incentives for monitoring quality we analyze a procurement problem in which the quality of the delivered product can be observed perfectly by the buyer and supplier but may not be verifiable i e may not be observable to any third party we present a set of plausible conditions under which the equilibrium welfare of both the buyer and supplier is higher when quality is verifiable than when it is unverifiable the welfare gain for the privately informed supplier arises even when the buyer has all the bargaining power thus the interests of the buyer and supplier coincide with regard to whether delivered quality should be made verifiable

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

population policies demographic structural changes and the chinese household saving puzzle abstract using combined data from population censuses and urban household surveys we study the effects of demographic structural changes on the rise of household savings in china variations in fines across provinces for unauthorized births under the one child policy and in cohort specific fertility influenced by the implementation of population control policies are exploited to facilitate identification we find evidence that older households with fewer adult children saved more middle aged households with fewer dependent children experienced increase in savings and younger households with fewer siblings also saved more these findings lend support to a simple economic model in which the effects of population control policies are investigated in the context of household saving decisions in china

consumer demand for fair trade evidence from a multistore field experiment abstract we provide new evidence on consumer demand for ethical products from experiments conducted in a u s grocery store chain we find that sales of the two most popular coffees rose by almost 10 when they carried a fair trade label as compared to a generic placebo label demand for the higher priced coffee remained steady when its price was raised by 8 but demand for the lower priced coffee was elastic a 9 price increase led to a 30 decline in sales while consumers attach value to ethical sourcing there is significant heterogeneity in willingness to pay for it

optimal allocation of mri scan capacity among competitive medical departments we consider an mri scanning facility run by a radiology department with limited capacity several medical departments compete for capacity and have private information regarding their demand for scans the fairness of the capacity allocation by the radiology department depends on the quality of the information provided by the medical departments we employ a generic bayesian game approach that stimulates the disclosure of true demand truth telling so that capacity can be allocated fairly we derive conditions under which truth telling is a bayesian nash equilibrium the usefulness of the approach is illustrated with a case study

learning by doing and learning from others human capital and technical change in agriculture household level panel data from a nationally representative sample of rural indian households describing the adoption and profitability of high yielding seed varieties hyvs associated with the green revolution are used to test the implications of a model incorporating learning by doing and learning spillovers the estimates indicate that i imperfect knowledge about the management of the new seeds was a significant barrier to adoption ii this barrier diminished as farmer experience with the new technologies increased iii own experience and neighbors experience with hyvs significantly increased hyv profitability and iv farmers do not fully incorporate the village returns to learning in making adoption decisions

crime and social interactions the high variance of crime rates across time and space is one of the oldest puzzles in the social sciences this variance appears too high to be explained by changes in the exogenous costs and benefits of crime we present a model where social interactions create enough covariance across individuals to explain the high cross city variance of crime rates this model provides an index of social interactions which suggests that the amount of social interactions is highest in petty crimes moderate in more serious crimes and almost negligible in murder and rape

word of mouth communication and social learning this paper studies the way that word of mouth communication aggregates the information of individual agents we find that the structure of the communication process determines whether all agents end up making identical choices with less communication making this conformity more likely despite the players naive decision rules and the stochastic decision environment word of mouth communication may lead all players to adopt the action that is on average superior these socially efficient outcomes tend to occur when each agent samples only a few others i introduction economic agents must often make decisions without knowing the costs and benefits of the possible choices given the frequency with which such situations arise it is understandable that agents often choose not to perform studies or experiments but instead rely on whatever information they have obtained via casual word of mouth communication reliance on this sort of easily obtained information appears to be common in circumstances ranging from consumers choosing restaurants or auto mechanics to business managers evaluating alternative organizational structures this paper studies two related environments in arguing that individuals reliance on word of mouth communication has interesting implications for their aggregate behavior first motivated by the diffusion of new technologies we consider a choice between two competing products with unequal qualities or payoffs and show that the structure of communication is important in determining whether the population as a whole is likely to learn to use the superior product second we consider a choice between two products or practices that are equally good and ask whether consumers are likely to herd onto a single choice or whether diversity will obtain even in the long run we explore the implications of word of mouth communication in a simple nonstrategic environment there is a large population of identical players each of whom repeatedly chooses between two possible actions each player s payoff is determined by his own

contracting for health services when patient demand does not reflect quality this paper analyses contracts to keep down costs while maintaining quality of health services when patient demand does not reflect quality there is then a natural role for forms of contract that have emerged during the reforms of the nhs in britain that differ from pure fixed price or cost reimbursement contracts the optimal form depends on whether the provider is entirely self interested or benevolent in having genuine concern for patient welfare with fully benevolent providers there are roles for block and cost and volume contracts with partially benevolent providers some degree of cost sharing is typically optimal

the population problem theory and evidence this study is concerned with the relationships among population growth poverty and environmental degradation with particular focus on the situation in developing countries the author rejects the concept of a general theory of fertility behavior in favor of an interpretation of these relationships which might be applicable to certain situations in the poorest parts of the indian subcontinent and sub saharan africa such situations include unacceptable risks of maternal death for poor illiterate women and a condemnation to extreme poverty in conditions of the deterioration of local resources and of the environment the author concludes that population growth rates are too high in certain specific areas and that an appropriate policy reaction to such conditions would be to try to change the options that men and women face so that their reasoned choice would be to lower their fertility

consumer activism producer groups and production standards we examine competition between groups of producers when consumers prefer costly ethical production technologies consumers are unable to identify or monitor production technologies producers can freeride on their group s reputation by substituting cheaper unethical technologies when an ethical technology is pareto optimal social pressures within competing producer groups can ensure long run dominance of groups relying most heavily on the ethical technology even if social pressures cannot support the choice of the ethical technology in the long run competition between producer groups can increase the average level of adoption of the ethical technology for an arbitrarily long period of time

ethical products less strong how explicit and implicit reliance on the lay theory affects consumption behaviors many consumers implicitly associate sustainability with lower product strength this so called ethical less strong intuition elsi poses a major threat for the success of sustainable products this article explores this pervasive lay theory and examines whether it is a key barrier for sustainable consumption patterns even more importantly little is known about the underlying mechanisms that might operate differently at the implicit and explicit levels of the consumer s decision making to fill this gap three studies examine how the implicit judgments that consumers activate automatically shape their consumption behaviors in concert with their more controlled explicit beliefs about sustainable products the main study investigates the elsi s imprint on actual shopping patterns and disentangles the implicit and explicit mechanisms of the lay theory this paper also asks how this negative influence can be attenuated by examining whether the consumer s interest in sustainable consumption reduces reliance on the elsi two follow up studies confirm the robustness from different methodological and practical perspectives implications for companies and policy makers are derived

optimal dynamic volume based price regulation abstract we consider a model of optimal price regulation in markets where demand is sluggish and asymmetric providers compete on quality using a spatial model which is suitable to investigate the health care and education sector we analyse within a dynamic set up the scope for price premiums or penalties on volume under the assumption of symmetric cost information we show that the socially optimal time path of quality provision off the steady state can be replicated by a simple dynamic pricing rule where the dynamic part of the rule is ex ante non discriminatory in the sense that the price premium or penalty on volume is common across providers despite their differing production costs whether the price schedule involves a penalty or a premium on volume relates to two concerns regarding production costs and consumer benefits which go in opposite directions price adjustments over time occur only through the price penalty or premium not time directly which highlights the simplicity and thus applicability of this regulation scheme

the manufacturing sector s environmental motives a game theoretic analysis what motivates manufacturing companies to make costly investments in producing in an environmentally clean manner the traditional argument is that such behaviour is value reducing and that therefore firms must be forced by regulation to invest in green production processes a counter argument is that firms have an incentive to make environmental investments in an attempt to attract green consumers and investors hence gaining competitive advantage over their rivals in this paper we employ a game theoretic approach that demonstrates that competing firms incentives to make voluntary investments in environmental clean up are affected by the size of the investment costs and the extent of consumer and investor green awareness we argue that an increase in green behaviour can be induced by a combination of governmental subsidies for firms that invest in environmentally clean production processes together with an education program that promotes green awareness amongst consumers investors and the managers themselves

the marketing challenge towards being profitable and socially responsible this article reviews the history of marketing thought in relation to social responsibility and business ethics the main objective of the article is to show that business can be profitable and socially responsible at the same time by practising the societal marketing concept more specifically it presents the development of a marketing philosophy discusses the influence of consumerism on the marketing concept and deals with ethics and social responsibility in marketing it is argued that organisations who adopt the societal marketing concept will be the ones most likely to make long run profits as well as be beneficial to society as a whole

hospital competition and quality with regulated prices we analyse the effect of competition on quality in hospital markets with regulated prices considering the effect of both introducing competition monopoly versus competition and increasing competition through either lower transportation costs increased substitutability or a higher number of hospitals with semi altruistic providers and a fairly general cost structure we show that the relationship between competition and quality is generally ambiguous in contrast to the received body of theoretical literature this is consistent with and potentially explains the mixed empirical evidence

the role of environmental management in consumers preferences for corporate social responsibility consumers in modern societies are increasingly sensitive to environmental performance by large and small corporations making it a crucial issue in the overall policy of corporate social responsibility the objective of this paper is to study the role of environmental performance in the profile of corporate social responsibility as perceived by consumers we utilize a stated preference approach to the study of consumer s preferences this approach allows for the evaluation in monetary terms of the trade offs that individuals can make between various aspects of corporate policy decisions including the extent of environmental performance the data is modelled by means of a mixture heuristics approach that allows us to study the utilization of various decision rules in the choice of products with various degrees of environmental performance the results show that the linear compensatory heuristic is the most extended across individuals and these subjects value most the policies concerned with environmental management those subjects opting for the non compensatory decision rule tend to focus on the attribute of good labour relations as the most salient factor defining corporate social responsibility in addition policy measures are relatively more valued for some products rather than for others suggesting that consumers discriminate between products when valuing companies environmental profiles

hospital quality choice and market structure in a regulated duopoly this paper analyzes the optimal structure of a regulated health care industry in a model in which the regulator cannot enforce what hospitals do unverifiable quality of health or does not know what hospitals know incomplete information about production costs or both we show that if quality is unverifiable the choice between monopoly and duopoly does not change with respect to the verifiable case but if there are fixed costs assumed to be quality dependent and the monopoly is the optimal market structure the quality level of the operative hospital decreases asymmetry of information introduces informational rents that can be reduced by increasing the most efficient hospital s market share a monopoly is chosen more often

quality and outside capacity in the provision of health services abstract this paper studies the effects of non contractibility of investment on the choices made by a health authority and a hospital which supplies a specific service non contractibility determines inefficiencies compared with any pareto efficient outcome the quality of the service chosen by the hospital is too low and the health authority relies too much on outside providers

perspectives on multinational enterprises in emerging economies multinational enterprises mnes play a pivotal role in the development of many emerging economies in consequence they became the focus of scholarly research by economists and policy analysts in contrast international business scholars have been comparatively uninterested in analysing this role of mnes yet they could make important contributions to these debates first studies taking the individual firms as starting point would enhance understanding of the interaction between mnes and the local environment second theories and research methodologies developed in international business research could provide new insights into the dynamics of mnes in emerging economies the objective of this paper is to motivate more international business scholars to engage in research on positive and negative spillovers from foreign direct investment fdi in emerging economy societies to advance this research agenda scholars need to analyse the specific activities and capabilities of the firms involved and the impact of fdi on the broader social and environmental context for management this agenda raises the ethical question to what extent ought businesses to care about their local stakeholders

deregulation and quality abstract this paper analyses within a static model the effect of quality concern on optimal market structure it focuses on cases where industry quality has public good like features and is not contractible it is shown that the introduction of competition raises a free rider problem which depresses quality the smaller producer free rides on its competitor investment which as a result underinvests to encourage the efficient producer to provide quality the regulator diminishes the market share of the opportunistic producer and chooses more often a monopoly however when quality is verifiable the introduction of competition entails no welfare loss whether the regulator observes total quality outcome or individual contributions

a complete solution to a class of principal agent problems with an application to the control of a self managed firm this paper considers a class of principal agent problems which have the following features 1 there is adverse selection because the principal ignores the value of one parameter of the agent s true characteristics 2 leaving aside the information parameter the principal s welfare as well as the agent s welfare depend on two types of variables observable to both of them the first ones possibly multidimensional are called action variable s and the second one which is one dimensional has in general the meaning of a money transfer 3 the principal is a stackelberg leader of the two person game he can commit himself to decision rules which are admissible on informational grounds he optimizes within the adequate class taking into account besides the agent s reaction one constraint which has generally the meaning of an individual rationality constraint and sometimes of a feasibility constraint the optimization is limited to the class of non stochastic mechanisms 4 the problem can also receive an alternative interpretation the principal faces a continuum of agents of unknown characteristics the distribution being known however stylized principal agent problems of this type have often been considered in the economic literature in particular the reader will later be able to recognize that the standard income tax model a la mirrlees 1971 the quality or quantity choice model of the monopolist a la mussa and rosen 1978 or maskin and riley 1982 and the model of government regulation of the private monopolist of baron and myerson 1982 all belong to

socioeconomic determinants of fertility in hebei province china an application of the sequential logit model the author uses micro level data from chinas 1985 in depth fertility survey to explore a wide range of socioeconomic and demographic factors as correlates of fertility at each birth parity while also examining the role of government population policy focusing upon parity levels of births rather than the timing of births fertility decisions are modeled in a sequential framework which assumes explicitly that at each parity level a couple decides whether or not to have another child taking all available information into consideration the model presented is simple in that it allows parents to decide sequentially whether or not to have additional children using a sequential logit model with logit functions estimated separately for each birth parity consideration of the data in the model found the occupational status of husband and place of childhood to be important factors affecting parity specific fertility while the education of wife and husband were of little effect mortality and sex of previous children are highly significant in affecting fertility at current parity in keeping with the expected replacement effect and preference for sons finally family planning policy introduced in the early 1970s seems to have led to a declining importance of socioeconomic variables in affecting cumulative fertility

identification of endogenous social effects the reflection problem this paper examines the reflection problem that arises when a researcher observing the distribution of behaviour in a population tries to infer whether the average behaviour in some group influences the behaviour of the individuals that comprise the group it is found that inference is not possible unless the researcher has prior information specifying the compisition of reference groups if this information is available the prospects for inference depend critically on the population relationship between the variables defining reference groups and those directly affecting outcomes inference is difficult to implossible if these variables are functionally dependent or are statistically independent the prospects are better if the variables defining reference groups and those directly affecting outcomes are moderately related in the population

fostering corporate social responsibility through public initiative from the eu to the spanish case should csr be approached only on a voluntary basis or should it be complemented with a compulsory regulatory framework what type of government intervention is more effective in fostering csr among companies this paper is an attempt to answer these questions reviewing the debate between proponents of the voluntary case and the obligatory case for csr and critically analysing current international government led initiatives to foster csr among companies and national government led initiatives in the eu area finally the paper focuses on the spanish case as an example of the failure of an exclusively voluntary approach despite the rapid uprise of csr spain is still far behind late in csr promotion strategies most action has been undertaken by companies themselves with no common guidelines governmental support or independent verification the lack of a regulatory framework for csr or ethical investment issues and the virtual absence of other indirect incentives explains the misbalance between private public and third sector initiatives based on the spanish context which is quite similar to other non oecd countries the authors call for a more proactive government position in csr related issues the conclusions of the paper detail the features of this regulatory framework and other policies to promote csr in spain as well as in other oecd countries

do consumers care about ethical luxury this article explores the extent to which consumers consider ethics in luxury goods consumption in particular it explores whether there is a significant difference between consumers propensity to consider ethics in luxury versus commodity purchase and whether consumers are ready to purchase ethical luxury prior research in ethical consumption focuses on low value commoditized product categories such as food cosmetics and high street apparel it is debatable if consumers follow similar ethical consumption patterns in luxury purchases findings indicate that consumers propensity to consider ethics is significantly lower in luxury purchases when compared to commoditized purchases and explores some of the potential reasons for this reduced propensity to identify or act upon ethical issues in luxury consumption

coordinating a socially responsible closed loop supply chain with product recycling abstract this paper analyzes the effects of corporate social responsibility csr and explores channel coordination in a socially responsible manufacturer retailer closed loop supply chain clsc by considering two areas profit maximization and social responsibility through product recycling the manufacturer is socially responsible and exhibits it by recycling of used product that it collects through the retailer using the reverse channel it is found that the channel s non profit maximizing motive through csr practice generates higher profit margin than the profit maximizing objective and revenue sharing contract resolves channel conflict recycling is a key factor for the wholesale price and hence pure profit of the manufacturer because variation of it may lead to decrement or increment even negative wholesale price thus there must be a limit of recycling for optimal benefit for best channel performance the manufacturer provides the retailer all revenues that it generates through recycling in the form of reward thus csr is purely a costly endeavor to the manufacturer moreover unlike the pure profit maximizing supply chain csr has the ability to vary surplus profit share

it s a matter of principle the role of personal values in investment decisions we investigate the role of personal values in an investment decision in a controlled experimental setting participants were asked to choose an investment in a bond issued by a tobacco company or a bond issued by a non tobacco company that offered an equal or sometimes lower yield we then surveyed the participants regarding their feelings toward tobacco use to determine whether these values influenced their investment decision using factor analysis we identified investment and tobacco related dimensions on which participants responses tended to load two of these factors relating to the societal impact of investment decisions and the health effects of tobacco were highly significant in determining whether participants selected a tobacco or non tobacco related investment more importantly we found that when the rate of return on a tobacco related investment exceeds the rate of return on an investment not involving tobacco by 1 the intensity of participant concerns about the societal effects of their investment decisions was especially important in determining investment choices this finding indicates that traditional wealth maximization approaches which do not consider the personal values of the investor omit an important factor that affects investment decisions

the role of personal values in fair trade consumption research in the u s on fair trade consumption is sparse therefore little is known as to what motivates u s consumers to buy fair trade products this study sought to determine which values are salient to american fair trade consumption the data were gathered via a web based version of the schwartz value survey svs and were gleaned from actual consumers who purchase fair trade products from a range of internet based fair trade retailers this study established that indeed there are significant interactions between personal values and fair trade consumption and that demographics proved to be useless in creating a profile of the american fair trade consumer

security analysts career concerns and herding of earnings forecasts several theories of reputation and herding see e g scharfstein and stein 1990 suggest that herding among agents should vary with career concerns our goal in this paper is to document whether such a link exists in the labor market for security analysts specifically we look at the relationship between an analyst s job tenure a proxy for career concerns and various measures of stock earnings forecast performance we establish the following key results 1 older analysts are more likely to produce earnings forecasts of firms before younger ones 2 their forecasts also deviate more from the consensus forecast than their younger counterparts we argue that these results are consistent with some reputational models of herding we also establish a number of auxiliary findings regarding the relationship between forecast accuracy and frequency of forecast revisions with job tenure

dynamic hypothetical bias in discrete choice experiments evidence from measuring the impact of corporate social responsibility on consumers demand abstract this paper is aimed at studying the dynamics of consumers preferences for corporate social responsibility the data come from both a discrete choice experiment dce and a field experiment conducted in a real market setting the results show that in a static setting first month predictions of a standard dce study and real market shares are statistically similar for the various profiles of corporate social responsibility however as time evolves real market shares present some dynamic patterns that are not mirrored by the standard dce predictions the overall conclusion is that differences between real market behavior and dce data can be attributed to the lack of learning experience or adaptation in dce surveys rather than to the hypothetical nature of the experiments

competition and equity in health care markets we provide a model where hospitals compete on quality under fixed prices to investigate how hospital competition affects i quality differences between hospitals and as a result ii health inequalities across hospitals and patient severities the answer to the first question is ambiguous and depends on factors related to both demand and supply of health care whether competition increases or reduces health inequalities depends on the type and measure of inequality health inequalities due to the postcode lottery are more likely to decrease if the marginal health gains from quality decrease at a higher rate whereas health inequalities between high and low severity patients decrease if patient composition effects are sufficiently small we also investigate the effect of competition on health inequalities as measured by the gini and the generalised gini coefficients and highlight differences compared to the simpler dispersion measures

towards shared social responsibility a study of consumers willingness to donate micro insurances when taking out their own insurance in recent years the concepts of charity and development aid have changed significantly present concepts combine direct money transfer with co production knowledge sharing and the development of products and services designed for the need of developing and transition economies the concept of micro financing is a financial service which has proven to allow for entrepreneurs in the respective countries to start up their businesses a relatively new financial product for these countries is micro insurance this article deals with the question whether consumers in the netherlands are willing to donate micro insurances and which factors influence this willingness to contribute to the non profit micro insurance approach of an insurance company the data were collected with questionnaires among a sample of the dutch population n 504 the data have been processed in a one way between groups anova a paired sample t test and an ordinal regression analysis the results show that approximately half of the dutch consumers are willing to pay an additional amount on their insurance premium for the donation of micro insurances the amount of the insurance premium did however not affect the willingness to donate wtd if consumers could choose the beneficiary less people are willing to donate yet those people are willing to donate more money in conclusion there is readiness among consumers to contribute to micro insurance via an insurance company that assists in setting up micro insurance projects this indicates a possible role for companies to act as an intermediary between philanthropic acts and consumers

regulating a monopolist with unknown costs we consider the problem of how to regulate a monopolistic firm whose costs are unknown to the regulator the regulator s objective is to maximize a linear social welfare function of the consumers surplus and the firm s profit in the optimal regulatory policy prices and subsidies are designed as functions of the firm s cost report so that expected social welfare is maximized subject to the constraints that the firm has nonnegative profit and has no incentive to misrepresent its costs we explicitly derive the optimal policy and analyze its properties in their classic papers dupuit 2 and hotelling 5 considered pricing policies for a bridge that had a fixed cost of construction and zero marginal cost they demonstrated that the pricing policy that maximizes consumer well being is to set price equal to marginal cost and to provide a subsidy to the supplier equal to the fixed cost so that a firm would be willing to provide the bridge this first best solution is based on a number of informational assumptions first the demand function is assumed to be known to both the regulator and to the firm while the assumption of complete information may be too strong the assumption that information about demand is as available to the regulator as it is to the firm does not seem unnatural a second informational assumption is that the regulator has complete information about the cost of the firm or at least has the same information about cost as does the firm this assumption is unlikely to be met in reality since the firm would be expected to have better information about costs than would the regulator as weitzman has stated an essential feature of the regulatory environment i am trying to describe is uncertainty about the exact specification of each firm s cost function in most cases even the managers and engineers most closely associated with production will be unable to precisely specify beforehand the cheapest way to generate various hypothetical output levels because they are yet removed from the production process the regulators are likely to be vaguer still about a firm s cost function 12 p 684 as this observation suggests it is natural to expect that a firm would have better information regarding its costs than would a regulator the purpose of this paper is to develop an optimal regulatory policy for the case in which the regulator does not know the costs of the firm one strategy that a regulator could use in the absence of full information about costs is to give the firm the title to the total social surplus and to delegate the pricing decision to the firm in pursuing its own interests which would then be to maximize the total social surplus the firm would adopt the same marginal cost pricing strategy that the regulator would have imposed if the regulator had

incomplete information and optimal market structure public purchases from private providers abstract market structure is endogenized in a normative model of public procurement featuring a social cost of profit product variety economies of scale and incomplete information about cost depending on parameters either sole sourcing or dual sourcing might be optimal however if the social cost of profit is positive but not too large incomplete information biases optimal market structure in favor of sole sourcing on the other hand this bias in favor of sole sourcing may be reversed if the social cost of profit is large an application to the publicly financed treatment for drug abuse motivates the analysis

consumer ethics an assessment of individual behavior in the market place a national sample of 362 respondents assessed the ethical predisposition of the american marketplace by calculating a consumer ethics index the results indicate that the population is quite intolerant of perceived ethical abuses the situations where consumers are ambivalent tend to be those where the seller suffers little or no economic harm from the consumer s action younger more educated and higher income consumers appear more accepting of these transgressions the results provided the basis for developing a four group taxonomy of consumers which retailers should find insightful in assessing potential consumer actions in a variety of situations

competition and quality in health care markets a differential game approach we investigate the effect of competition on quality in health care markets with regulated prices taking a differential game approach in which quality is a stock variable using a hotelling framework we derive the open loop solution health care providers set the optimal investment plan at the initial period and the feedback closed loop solution providers move investments in response to the dynamics of the states under the closed loop solution competition is more intense in the sense that providers observe quality in each period and base their investment on this information if the marginal provision cost is constant the open loop and closed loop solutions coincide and the results are similar to the ones obtained by static models if the marginal provision cost is increasing investment and quality are lower in the closed loop solution when competition is more intense in this case static models tend to exaggerate the positive effect of competition on quality
