the effect of slack diversification and time to recall on stock market reaction to toy recalls abstract past toy recalls have led to an increase in consumer concerns while toy manufacturers and retailers increasingly outsource and create longer supply chains making it more challenging for them to ensure toy safety this article examines firms making toy recall announcements to assess the impact operational characteristics have on the negative stock market reaction to the announcement 135 toy recall announcements in the u s from 1979 to 2016 were analyzed using event study and cross sectional regression while a toy recall announcement results in a negative stock market reaction our results show that greater levels of business diversification inventory slack and a longer time to recall are all associated with a less negative stock market reaction in contrast greater capacity slack is associated with a more negative stock market reaction we find no evidence that geographic diversification or financial slack influences the stock market reaction nor have reactions changed appreciably over time this article contributes to the product harm and product recall literature by focusing on these operational elements managers should be aware of the benefits of greater slack and business diversification while planning their business and the impact of a longer time to recall

government education expenditures in early and late childhood human capital investment in early childhood can lead to large and persistent gains beyond this window of opportunity human capital accumulation is more costly despite compelling evidence in support of this notion government education spending is allocated disproportionately toward late childhood and young adulthood we consider the consequences of a reallocation using an overlapping generations model with private and public spending on early and late childhood education taking as given the higher returns to early childhood investment we find that the current allocation may nonetheless be appropriate when we consider a homogeneous population this can hold for moderate levels of government spending with heterogeneity this can hold for middle income workers lower income workers by contrast may benefi tf rom a reallocation

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

market forces and aircraft safety thecaseofthedc 10 the may 25th 1979 chicago dc 10 crash provides the opportunity to test an important proposition in the theory of consumer product safety can market forces provide safety when products are too complex to permit buyer prepurchase inspection this paper combines economic theory with modern finance theory to measure the cost of the crash to shareholders of the plane s manufacturer mcdonnell douglas the results indicate that the dc 10 crash resulted in a 200 million loss to mcdonnell douglas stockholders and that this amount exceeds any reasonable estimate of regulatory or liability costs

increasing the capital income tax may lead to faster growth this paper shows that under rather mild conditions higher capital income taxes lead to faster growth in an overlapping generations economy with endogenous growth government expenditures are financed with labor income taxes as well as capital income taxes since capital income accrues to the old taxing it reliefs the tax burden on the young and leaves them with more income out of which to save we argue that savings are sufficiently interest inelastic so that higher savings and therefore higher growth result the basic argument is not seriously challenged by a grandfather clause for initial capital or by the old receiving some labor income as well the reasoning is similar to feldstein 1978 auerbach 1979 and in particular jones and manuelli 1992 but in contrast to the conventional wisdom about the effect of capital income taxation as say in lucas 1990

public versus private investment in human capital endogenous growth and income inequality in this paper we present an overlapping generations model with heterogeneous agents in which human capital investment through formal schooling is the engine of growth we use simple functional forms for preferences technologies and income distribution to highlight the distinction between economies with public education and those with private education we find that income inequality declines more quickly under public education on the other hand private education yields greater per capita incomes unless the initial income inequality is sufficiently high we also find that societies will choose public education if a majority of agents have incomes below average

public funding of higher education abstract recent criticism from different sides has expressed the view that with scarce resources there is little justification for massive public funding of higher education central to the debate is the conjecture that colleges and universities use their resources inefficiently and focus insufficiently on their mission to expand students human potential our aim in this paper is to examine the theoretical premises of this conjecture in a small open economy and uncover the conditions under which public investment in higher education is efficient and desirable we analyze non stationary equilibria of an olg economy characterized by perfect capital mobility intergenerational transfers and a hierarchical education system the government uses income tax revenues to finance basic education and support higher education that generates skilled labor given this the following issues are considered a the impact of education and international markets on the equilibrium number of low skilled and skilled workers in each generation b the economic efficiency of public subsidies to higher education in generating skilled human capital c the endogenous support for a government s educational policies found in a political equilibrium

the changing role of consumers and suppliers in a food safety event the 2006 foodborne illness outbreak linked to spinach abstractthis article provides a means for testing whether buyers or sellers are responsible for a drop in sales following a market shock we show that suppliers responses dominated the market reaction to the 2006 us food and drug administration warning to avoid fresh spinach contaminated with potentially deadly bacteria escherichia coli o157 h7 a modified durbin wu hausman test for temporary price endogeneity is developed and used in a leafy green vegetable demand model test results indicate the price of bagged spinach was exogenous before the announcement but endogenous for approximately 12 weeks afterward we show these results are consistent with the notion that suppliers temporarily limited the availability of spinach to consumers instead of consumers choosing the quantity purchased given exogenous prices it was suppliers who limited the quantity marketed and consumers choices established the market price

a population macroeconomic growth model for currently developing countries abstract this paper constructs a theoretical model that predicts as observed in some currently developing countries that the average school enrollment ratio may fall even when the average fertility rate declines unlike existing models the current analysis indicates that economic growth may slow down when a fertility transition starts asymmetric behavior with respect to fertility and education between households stemming from income inequality plays an important role in generating this result we examine the implications of an education subsidy policy contrary to intuition in some circumstances this policy may decrease the average school enrollment ratio and future economic growth

public spending on education and the incentives for student achievement we build a model where homogeneous workers can accumulate human capital by investing in education schools combine public resources and individual effort to generate productive skills if skills are imperfectly compensated then in equilibrium students may under invest in effort we examine the effect on human capital accumulation of three basic education finance policies increased tuition subsidies may not be beneficial because they increase enrolment but they may lower the incentives for student achievement hence the skill level policies directed at enhancing the productivity of education or making degrees more informative are more successful at improving educational outcomes

impacts of meat product recalls on consumer demand in the usa the impact of meat product recall events on consumer demand beef pork poultry and other consumption goods in the usa is tested empirically beef pork and poultry recall indices are constructed from both the food safety inspection service s meat recall events and from newspaper reports over the period 1982 1998 following previous product recall studies recall indices are incorporated as shift variables in consumers demand functions estimating an absolute price version of the rotterdam demand model findings indicate that food safety inspection service s meat recall events significantly impact demand and newspaper reports do not moreover although elasticities related to recall events are significant they are small in magnitude relative to price and income effects any favourable effects on the demands of meat substitutes for a recall are offset by a more general negative effect on meat demand the general negative effect indicates a shift out of meat to non meat consumption goods

policy variability productive spending and growth in this paper i present two models with policy variability arising from randomness in the provision of productive public spending in the first model public spending enters as an input in output production in this case i find that the relationship between policy variability and growth depends critically on the technological parameters of the production function in the second model public spending enters as an input in the education sector of the economy in this case i find that policy variability retards growth as individuals respond to increased uncertainty by actually reducing rather than increasing their investment in human capital

booms and busts in the uk housing market the often volatile behaviour of uk house prices between 1957 and 1994 is analysed in an annual econometric model theory suggests that financial liberalisation of mortgage markets in the 1980s should have led to notable shifts in house price behaviour the evidence supports the predictions of theory suggesting shifts took place in wealth effects as in the consumption function and that real interest rates and income expectations became more important the presence of transactions costs suggests important nonlinearities in house price dynamics the paper also contains an explicit econometric treatment of expectations demography supply spillovers from the rented sector and of composition biases in the official house price index

the impact of external parties on brand name capital the 1982 tylenol poisonings and subsequent cases an examination of the 1982 tylenol poisonings reveals stock market losses to johnson johnson that far exceed direct costs and losses shared with other pain reliever producers this evidence provides support for the klein and leffler 1981 theory of brand names as quality assuring mechanisms of the subsequent cases only the 1986 tylenol poisonings were associated with significant stock market losses prior to the 1982 and 1986 tylenol poisonings tylenol was the number one pain reliever whereas the other pain relievers that were poisoned had a much lower level of brand name capital to lose

market incentives for safe commercial airline operation using a sample of nearly all fatal u s airline accidents between 1960 and 1985 this paper attempts to quantify the costs that airlines incur due to crashes the potential costs include those due to loss of life and equipment tort liability increased regulatory oversight and loss of demand as consumers turn away from products perceived to be unsafe examination of the deviations from expected demand following accidents reveals little or no effect prior to airline deregulation and weak indication of a response to recent crashes these results are consistent with the changes in an airline s equity value following an accident which are statistically significant but quite small relative to the total social cost of the accident

an investigation of real versus perceived csp in s p 500 firms firms are spending billions annually in the name of corporate social responsibility csr whilst markets are increasingly willing to reward good and responsible firms they lack the instruments to measure corporate social performance csp to convince investors and other stakeholders firms invest heavily in building a reputation for good corporate behaviour this article argues that reputations for csp are often unrepresentative of true csp and investigates how differences in perceived and actual as measured by the fortune and kld databases respectively can partly be explained by firm characteristics amongst other things it finds that overrated firms are more likely to be relatively big profitable operating in non polluting but competitive industries and with no history of wrong doings to their primary stakeholders they will also typically spend a lot of effort satisfying the claims of their secondary stakeholders above all the results emphasise the need for researchers to recognise that the databases measure different phenomenon and are not interchangeable

what does reputation really assure the relationship of trademarks to expectations and legal remedies i introduction klein and leffler 1981 and shapiro 1982 1983 have shown that a firm that engages in repeat transactions has an incentive to use the market as distinct from formal legal processes to assure the quality of its product the firm charges a price above salvageable costs of production and invests the premium in reputation trademark capital that it forfeits wholly or in part if it allows quality to fall below the standards it represents to its customers 1 the quality assurance hypothesis seems to be supported by stock market event studies such as those by jarrell and peltzman 1985 and karpoff and lott 1993 which show that product recalls airline crashes deceptive advertising and fraud result in trademark losses the quality assurance hypothesis however does not explain the massive size of these losses which typically are many times the outlays incurred by the firm as a result of the event the law and economics literature on contracts offers an answer to this and related puzzles suggesting that trademark capital does more than assure quality it assures specific performance that is fulfillment of the precise terms of the contract 2 after developing the specific performance hypothesis section ii we show that it is supported by the evidence from event studies furthermore it explains other phenomena not covered by the quality assurance hypothesis including why competitors of firms whose products are recalled lose wealth why some damages such as those in airline crashes intentionally fail to provide full compensation and why firms who sell to other firms also invest in trademark capital section iii we conclude with a summary and a few remarks on the issue of market versus legal forces section iv ii the specific performance hypothesis the quality assurance hypothesis focuses on the problems that arise when the physical characteristics of a commodity are costly to determine even after purchase and sellers warranties and quality representations are costly to enforce because higher quality usually costs more to produce and can be sold at a higher price producers have an incentive to represent their goods as being of higher quality than they really are or having established a reputation to cut quality and costs when consumers observe that the quality of the goods they purchase is lower than they had been led to believe they shift to lower cost lower quality goods whose quality is easier to determine higher quality goods seemingly are driven off the market klein and leffler 1981 hypothesize that a firm that engages in repeat transactions can gain by producing higher quality goods charging a price above salvageable costs of production and investing the premium in firm specific trademark capital the value of this trademark also described as reputation or goodwill is the present value of the expected stream of price premiums misrepresentation causes a reduction in this income stream and a corresponding loss in trademark capital 3 thus trademarks assure quality without a third party to enforce the contract 4 a buyer however is concerned about other characteristics of a transaction besides the physical attributes of the product the expected harm if the seller breaches the contract for example by misrepresenting the product failing to deliver it on time or failing to provide future service and the ability of the legal system to assure full compensation also matter accordingly a seller who engages in repeat transactions has an incentive to provide a bond that assures specific performance rather than just product quality when a breach results in damages that are hard to measure and the legal system does not enforce contracts costlessly the next task therefore is to examine the limitations of the legal system in enforcing contracts and providing compensation in case of breach specific performance and penalty clauses the courts could require contracting parties to provide specific performance

brand names ignorance and quality guaranteeing premiums recent literature contains several theories of how self enforcing agreements rely on repeat purchase mechanisms to ensure product quality some have suggested the use of advertising as a signal of future actions in such games this article extends these recent studies for the case where firms face temporary changes in cost or demand curves and offers an initial attempt at providing a statistical test of the klein leffler model it is found that the deviations in the advertising sales ratio from the levels that can be explained by industry specific characteristics are consistently contrary to what their model predicts these results hold over a very wide range of depreciation rates for advertising and for the many individual industries examined the results are only weakly affected when the presence of measurement error is explicitly recognized

international migration housing demand and access to homeownership in the uk since the mid 1980s the uk has experienced a prolonged period of net international migration with debate as to its impact on economic benefits and costs a third of projected new households in the next 15 20 years are expected to come from net migration this article examines international migration and housing demand in light of the conventional understanding of british housing markets and the extent to which there are differences in demand and access to homeownership across international migrant groups demographic and socioeconomic factors as well as length of residence are found to be significant determinants of homeownership however there are also differences in homeownership attainment that may be related to ethno cultural differences or unobserved wealth effects and mortgage market institutional factors the role of socioeconomic factors has implications for skills based migration to the uk if a policy concern is house price pressure and migration

productive government expenditures and long run growth the purpose of this paper is to review some of the recent developments in endogenous growth models specifically our focus is on the growth effects of productive government spending in dynamic general equilibrium models we use a simple overlapping generations model as our basic framework and illustrate the role of taxes and spending we then examine several related issues nonrivalry in publicly provided goods existence and uniqueness of competitive equilibrium endogenous public policy ways of financing public expenditures composition of publicly provided goods and services and private alternatives finally we review some empirical results related to output elasticity of public capital and educational expenditures

planning for housing in the post barker era affordability household formation and tenure choice the barker review of housing supply recommended the greater use of market indicators as the basis for providing sufficient land for future housing requirements worsening affordability would be a sign that more land is required however the traditional approach to land release used by planners is based on trend household projections the paper shows that this will typically lead to worsening affordability over time the paper therefore develops an alternative economic model more suitable to the post barker era covering both household formation and tenure choice the model is used to analyse a range of policy issues including raising home ownership rates and home ownership sustainability

on the taxation of human and physical capital in models of endogenous growth abstract this paper studies the effects of factor income taxation and of subsidies to human capital accumulation in models of endogenous growth it examines in particular how these effects depend on the specification of the leisure activity and on the technology and tax treatment of the sector producing human capital it shows that the negative effects of factor income taxes on economic growth are stronger when the human capital sector is a market good under these circumstances a subsidy to human capital accumulation can offset the direct growth effects of labor taxation making it akin to a consumption tax the paper then briefly discusses the normative implications of the analysis for the optimal taxation of factor incomes

static and dynamic in efficiency in public goods provision we analyze with a methodological focus in which cases and under which hypotheses the dispersion of the distribution of individual demands affects the provision of public goods we derive implications in terms of static and dynamic in efficiency

taxation and long run growth abstract a number of recent papers have investigated the growth effects of tax reforms in the context of neoclassical growth models with human capital growth effects were found to be large but highly sensitive to parameter choices this paper shows that growth effects are smaller and much less sensitive in models that generate realistic life cycle behavior which requires that households are finitely lived but generations may be altruistically linked and face diminishing point in time returns in human capital accumulation reasonable upper bounds for growth effects in such models are less than one third of some values reported in the literature

product reliability and firm value the experience of american and japanese automakers 1973 1992 in a typical month several recall campaigns of motor vehicles are announced by automobile manufacturers they are carried out to correct defective vehicles whether safetyor pollution related recalls imply that the products made available to consumers are not what they were supposed to be a question arises then as to whether and how much the offending automakers are affected by these recall campaigns the answer to this question has been ambiguous in the literature we have two purposes in this paper first on the basis of a longer and broader database we offer additional and more conclusive evidence that documents significant and negative market reactions to automobile recall announcements our finding therefore helps to resolve the ambiguity in the literature on this question second we offer new evidence on japanese automobile companies they too suffer from significant and negative stock market reactions but the incidence of recalls is less frequent perhaps as a result the magnitude of the stock market reaction to each recall is somewhat larger nevertheless because recalls are much less frequent the total losses

the effects of compulsory schooling on growth income distribution and welfare abstract in this paper we consider an olg model with productive capital and human capital affecting the quality of labor in each generation parents invest in their children s education but disregard its external effect on the aggregate production function government intervention in providing compulsory schooling increases economic growth along the equilibrium path while the intragenerational income distribution becomes more equal also in the long run the majority of individuals in each generation are better off due to compulsory schooling

the economics of schooling production and efficiency in public schools n recent years public and professional interest in schools has been heightened by a spate of reports many of them critical of current school policy these policy documents have added to persistent and long standing concerns about the cost effectiveness and fairness of the current school structure and have made schooling once again a serious public issue as in the past however any renewed interest in education is likely to be short lived doomed to dissipate as frustration over the inability of policy to improve school practice sets in this frustration about school policy relates directly to knowledge about the educational production process and in turn to underlying research on schools although the educational process has been extensively researched clear policy prescriptions flowing from this research have been difficult to derive 2 there exists however a consistency to the research findings that does have an immediate application to school policy schools differ dramatically in quality

public investment in infrastructure in a simple growth model abstract in this paper we examine the implications for capital accumulation when infrastructure enters as an external input into private production functions in our model infrastructure is nonexclusive but may exhibit varying degrees of nonrivalry revenues from uniform taxes on capital and labor income are used to finance public investment in infrastructure we show that the optimal tax rate is independent of the degree of nonrivalry when production exhibits constant returns to augmentable factors the equilibrium displays constant growth for most parameters the growth rate depends on the population size under decreasing returns the optimal trajectory exhibits monotonic convergence to a steady state level

public schooling college subsidies and growth abstract how does the mix of public education expenditures across primary and secondary k 12 education and post secondary college education influence economic growth to address this i build an overlapping generations endogenous growth model human capital is accumulated through compulsory k 12 education and through optional college education government uses tax revenue to provide quality in k 12 schooling and to subsidize college tuition when total expenditures are small all funds should provide k 12 quality when expenditures are above a critical value a positive share should subsidize tuition the share should increase with total expenditures and with the degree of complementarity of human capital accumulated through the two types of education also increased education spending is more likely to increase growth when a larger share subsidizes tuition

long run growth and welfare effects of public policies with distortionary taxation abstract in a one sector growth model with infrastructure investment we study the impact of fiscal policies on growth the government collects taxes on labor income and profits the government uses these revenues to purchase infrastructure investment provide utility enhancing government services and to provide transfer payments to the households we show that the balanced growth rate is an increasing function of the percent of government revenues that goes to infrastructure we find that the growth maximizing mix of taxes depends on the elasticity of substitution between inputs in particular with distortionary taxes the growth maximizing tax rate on capital is higher the lower the elasticity of substitution between private physical capital and public capital in addition the growth maximizing size of the government is higher when the elasticity of substitution between public and private inputs is low we also investigate welfare effects of other public expenditures as well depending on the elasticity of substitution in production the welfare implications of different public policies can be substantial

the corporate social responsibility of pharmaceutical product recalls an empirical examination of u s and u k markets the pressure on companies to practice corporate social responsibility csr has gained momentum in recent times as a means of sustaining competitive advantage in business the pharmaceutical industry has been acutely affected by this trend while pharmaceutical product recalls have become rampant and increased dramatically in recent years no comprehensive study has been conducted to study the effects of announcements of recalls on the shareholder returns of pharmaceutical companies as product recalls could significantly damage a company s reputation profitability and brand integrity this paper investigates the effect on shareholder wealth and the extent to which the adoption of csr practices by pharmaceutical companies in the united kingdom u k and the united states u s the two largest markets for pharmaceutical products in the world affected market reactions surrounding product recall announcements the analysis of product recall announcements from 1998 to 2004 compiled from the pharmaceutical journal and u s food and drug administration enforcement reports revealed marked differences in the way market participants in the two countries responded to news of product recalls u s investors penalised firms according to the severity of product defects while u k investors were indifferent while u k investors rewarded product recalls by firms which were not usually csr active u s investors punished non csr active firms that performed recalls these observations could pose strategic challenges to pharmaceutical firms operating in both countries

the economic side effects of dangerous drug announcements immediately prior to the passage of the 1962 food and drug administration amendments there were a number of drugs recalled from markets worldwide announcements about the dangerous side effects of these drugs were associated with lower share prices for their manufacturers and the industry as a whole we perform several analyses to sort out alternative explanations for the observed declines we find that dangerous drug announcements had no effect on the sales of other drugs and did not affect the share values of european drug makers doing little business in the united states we also find that share price reductions associated with recalls in the 1970s and 1980s were confined to the manufacturers of the recalled drugs these patterns are consistent with the hypothesis that drug company shareholders viewed the recalls in the early 1960s as signals of an increase in the cost of compliance with new and more stringent drug testing requirements

does compulsory school attendance affect schooling and earnings we establish that season of birth is related to educational attainment because of school start age policy and compulsory school attendance laws individuals born in the beginning of the year start school at an older age and can therefore drop out after completing less schooling than individuals born near the end of the year roughly 25 percent of potential dropouts remain in school because of compulsory schooling laws we estimate the impact of compulsory schooling on earnings by using quarter of birth as an instrument for education the instrumental variables estimate of the return to education is close to the ordinary least squares estimate suggesting that there is little bias in conventional estimates every developed country in the world has a compulsory schooling requirement yet little is known about the effect these laws have on educational attainment and earnings 1 this paper exploits an unusual natural experiment to estimate the impact of compulsory schooling laws in the united states the experiment stems from the fact that children born in different months of the year start school at different ages while compulsory schooling laws generally require students to remain in school until their sixteenth or seventeenth birthday in effect the interaction of school entry requirements and compulsory schooling laws compel students born

education social security and growth abstract we study the role of government s allocation of tax revenues between two outlays public investment in education a transfer to the young generation and social security benefits to the older generation in an overlapping generations economy with pay as you go social security and altruistically motivated transfers from parents to children we analyze how the allocation of the tax revenues between the two outlays affects growth and welfare in competitive equilibria a we obtain comparative dynamics results for nonstationary equilibria subject to a change in the allocation profile b for stationary equilibria we show that for a given allocation profile of the tax revenues educational subsidies can either increase the growth rate or decrease it depending on the parameters of the model preferences production function and the tax rate c if government seeks to allocate funds in a way that maximizes the growth rate we demonstrate that under some plausible conditions it is not optimal to maintain pay as you go social security however if parents preferences combine strong concern for their retirement with significant degree of altruism towards their children then pay as you go social security system does enhance growth and welfare

regulation and firm size fda impacts on innovation this article estimates the highly differential impacts of fda regulations on pharmaceutical firms of various sizes where size is measured as scale of r d expenditures estimation is performed using the method of maximum quasi likelihoods using productivity trends of the united kingdom as a control to isolate fda regulatory effects in the united states it is shown that smaller u s pharmaceutical firms suffered devastating reductions in research productivity because of fda regulations in contrast the largest u s pharmaceutical firms apparently benefited from regulation as sales gains due to reduced competition more than offset their quite moderate declines in research productivity

estimating the market effect of a food scare the case of genetically modified starlink corn abstract in 2000 a genetically modified corn variety called starlink that was not approved for human consumption was discovered in the food corn supply to estimate the price impact of this event on the u s corn market we develop the relative price of a substitute method this method applies not only to the starlink event but also to rare events in other markets we find that the contamination led to a 6 8 discount in corn prices and that the suppression of prices lasted for at least a year

does school quality matter returns to education and the characteristics of public schools in the united states this paper estimates the effects of school quality measured by the pupil teacher ratio average term length and relative teacher pay on the rate of return to education for men born between 1920 and 1949 using earnings data from the 1980 census we find that men who were educated in states with higher quality schools have a higher return to additional years of schooling rates of return are also higher for individuals from states with better educated teachers and with a higher fraction of female teachers holding constant school quality measures however we find no evidence that parental income or education affects average state level rates of return

the financial impact of product recall announcements in china abstract a product recall can be viewed as a firm s worst nightmare although the long term damage to brand equity and company reputation may be difficult if not impossible to quantify the short term impact on shareholders wealth is readily estimable while many studies have examined this issue in the western context little is known about the financial impact of a product recall announcement in china to advance the knowledge about the financial impact of a product recall announcement we explore this issue using event study methodology in general our findings are congruent with previous research that product recalls result in negative abnormal returns interestingly however we found that chinese companies suffered from greater financial losses than their western counterparts did this study also provides evidence that the chinese food industry experiences a more severe stock market reaction than the automobile industry and that a passive recall strategy was associated with a more negative stock market reaction than a proactive recall strategy we conclude with several future research avenues for global research on product recalls

the economics of nested names name specificity reputations and price premia a good can be identified by its region or country of origin the firm that produces it and its product name in other words names can nest within each other to categorize goods with increasing specificity this article develops a conceptual framework for jointly analyzing the effect of product firm and collective reputations on market price the model is estimated via quantile regression with california wine market data the results portray how the structure and relative importance of reputations change as product prices vary specifically reputation premia migrate from collective to specific names as prices increase

market incentives for safe foods an examination of shareholder losses from meat and poultry recalls meat and poultry recalls while voluntary are carried out under governmental oversight if firms have financial incentives to avoid being implicated in a recall situation governmental involvement in recalls may cause firms to internalize social costs when making investment decisions concerning food safety controls to examine these incentives we analyze federally supervised meat and poultry recalls from 1982 to 1998 within an event study results show significant shareholder losses when publicly traded food companies are implicated in a recall involving serious food safety hazards we find no evidence that the stock market reacts negatively when recalls involve less severe hazards each year unsafe foods sicken millions and lead to losses in terms of life and productivity mead et al estimate that foodborne pathogens account for 76 million illnesses and 5 000 deaths in the united states given human error and the limitations of food safety technology food items that pose undue risks to the public will be distributed from time to time when this occurs the firms involved stand to incur expenses related to recovering disposing of or reconditioning potentially contaminated products already placed on the market in addition negative publicity can lead to reductions in product demand and may erode prior investments in reputation and brand capital these firms may also face costs from liability claims associated with an outbreak of food related illnesses or injury our main objective in this paper is to examine reductions in food company valuations that result from food contamination incidents we focus specifically on meat and poultry firms that have shipped products that were later recalled for food safety reasons because preventative actions taken by firms can affect the probability of being implicated in a product recall situation the wealth that is lost when companies are required to recall

does food safety information impact u s meat demand a theoretical model of consumer response to publicized food safety information on meat demand is developed with an empirical application to u s meat consumption evidence is found for the existence of pre committed levels of consumption seasonal factors time trends and contemporaneous own and cross commodity food safety concerns the average demand response to food safety concerns is small especially in comparison to price effects and to previous estimates of health related issues this small average effect masks periods of significantly larger responses corresponding with prominent food safety events but these larger impacts are short lived with no apparent food safety lagged effects on food safety concerns in the united states have dramatically increased in the past decade with regard to incidences of contaminated meat products concerns have arisen because contaminated meat products can result in serious risk to the well being and health of consumers contamination comes from a myriad of sources including but not limited to outbreaks of listeria monocytogenes escherichia coli e coli and salmonella centers for disease control and prevention food safety problems are not isolated to the united states as other unsafe contaminates in meats have emerged across the world including highly publicized outbreaks of bovine spongiform encephalopathy bse in europe the potential impacts of publicized food safety events on consumer s demand for meat products in the united states include own effects on the demand for the contaminated meat involved as well as cross effects impacting the demand for other meats the objective of this article is to investigate whether publicized food safety concerns surrounding beef pork and poultry chicken and turkey have impacted meat consumption food safety indices are constructed separately for beef pork and poultry

market forces and commercial aircraft safety this paper investigates the wealth impact on aircraft manufacturers of crashes involving their aircraft the author attempts to separate out the regulatory tort law and endogenous market components of these costs using stock market data the results indicate that on average the manufacturer suffers a wealth loss of 21 3 million as the result of a fatal crash in which the structural integrity of the aircraft is at issue the analysis suggests that not all of this amount can be attributed to regulatory or tort law mechanisms and that market forces play a role in providing air travel safety copyright 1987 by blackwell publishing ltd

estimating the structure of market reaction to news information events and lumber futures prices we develop a new event study technique the distributional event response model derm appropriate to relatively slowly evolving information events we apply the model to twelve years of daily lumber futures prices and analyze the effects of three different types of information releases a monthly housing starts estimates b aperiodic administrative and judicial announcements about u s canada trade disputes and c novel and unprecedented court decisions related to the endangered species act esa the information releases are different in ways that predict their relative speeds of impoundment in prices we find that housing start events are absorbed more quickly than trade events which are absorbed more quickly than esa events

public policies and convergence abstract this paper employs a dynamic framework to compare the effects of alternative government policies on convergence of industrialized economies to the technology frontier the government s instruments include facilitating private investment and education policy the latter enhances skills of heterogenous specialists and implies the decision on their respective shares the analysis distinguishes between an isolated policy of a single economy and coordinated policies of various countries which policy maximizes the speed of convergence is crucially affected by the economy s state of development a policy switch between the mentioned instruments while catching up may be preferable

ability biased technological transition wage inequality and economic growth thispaper develops a growthmodel characterizedbyability biasedtechnological transition in which the evolution of technology education attainment and wage inequality is consistent with the observed pattern in the united states and other advanced countries over the past several decades it argues that an increase in the rate of technological progress raises the return to ability and simultaneously generates an increase in wage inequality between and within groups of skilled and unskilled workers an increase in average wages of skilled workers a temporary decline in average wages of unskilled workers an increase in education and a productivity transitory slowdown

optimal public investments in education and endogenous growth optimal public investments in human capital through subsidizing private education or providing public education are considered in an endogenous growth model with externalities subsidizing private education stimulates growth improves welfare and has no distributional effect while reducing income inequality as in the literature public education hinders the growth of the average income unless externalities are strong enough and reduces the welfare of the median agent unless initial income inequality is sufficiently high societies with high income inequality may provide public education and will replace it with subsidized private education in some future periods as income converges copyright 1996 by the editors of the scandinavian journal of economics

intra industry information transfers associated with earnings releases abstract the impact that a firm s earnings releases have on the stock prices of other firms in its industry is examined for an identifiable sub set of firms the results are consistent with a significant information transfer occurring between the earnings release firm and the other firms in its industry this subset is identified by examining the impact of the release on the stock price of the announcing firm the magnitude of this impact is more significant for a sample of firms which have a larger percentage of their revenues in the same line of business as the earnings release firm vis a vis a sample with a lower percentage of their revenues from the same line of business alternative interpretations of the empirical results are also discussed the research findings have implications for information content and market efficiency research and for research on policy issues associated with disclosure regulation

public versus private investment and growth in a hierarchical education system abstract the paper studies the interaction between public and private spending in a two stage education framework k 12 and tertiary education and their effects on economic growth we find that an increase in the overall education public spending crowds out the total level of private contributions and increases the share of resources that households devote to k 12 education for a given public budget a higher share of k 12 public funding induces higher private education spending overall of which a larger share goes towards higher education the model broadly matches data on education finance in the oecd countries the calibrated parameter values suggest that at both stages public and private inputs are good yet imperfect substitutes with a higher degree of complementarity in basic education we show that the growth maximizing share of public spending devoted to k 12 should be high irrespective of the size of the public budget using the calibrated model to compare the structure of education funding in the eu and the us we find that to maximize growth high tax countries should use more of their public resources in tertiary education relative to low tax countries this suggests that us efforts to improve k 12 education and the reform of higher education in europe are consistent with the objective of increased economic growth

homeownership for future generations in the uk this paper constructs a housing market model to analyse conditions for different generations of households in the uk previous policy work has suggested that baby boomers have benefitted at the expense of younger generations the model relies on a form of financial accelerator in which existing homeowners reinvest a proportion of the capital gains on moving home the model is extended to look at homeownership probabilities it also explains why an increasing share of mortgages has gone to existing owners despite market liberalisation and securitisation in addition the model contributes to the explanation of volatility

the effects of class size on student achievement new evidence from population variation abstract i identify the effects of class size on student achievement using longitudinal variation in the population associated with each grade in 649 elementary schools i use variation in class size driven by idiosyncratic variation in the population i also use discrete jumps in class size that occur when a small change in enrollment triggers a maximum or minimum class size rule the estimates indicate that class size does not have a statistically significant effect on student achievement i rule out even modest effects 2 to 4 percent of a standard deviation in scores for a 10 percent reduction in class size

public education expenditures taxation and growth linking data to theory governments around the world have taken a prominent role in financing education while justifications for this involvement are varied a common motivation is that education expenditures are a key to sustained economic growth economic theory provides a foundation for this belief many papers in the endogenous growth literature have formalized a link between public education expenditures human capital accumulation and long term growth while theory assigns public education expenditures a key role in growth empirical support for the link is mixed as highlighted by blankenau and simpson 004 the disconnect between theory and data can be reconciled by taking a closer look at the theory in nearly every model where growth is fueled by public education expenditures a nonmonotonic relationship between expenditures and growth can arise public education spending increases growth while taxes may decrease growth leaving the net effect ambiguous thus economic theory shows that to identify the growth effects of expenditures one must account for any offsetting effects of the requisite taxation most empirical investigations of these effects do not explicitly control for the method of finance however in contrast we make the relationship between expenditures taxation and growth central to our analysis we estimate a

event studies in economics and finance the event study is an important research tool in economics and finance the goal of an event study is to measure the effects of an economic event on the value of firms event study methods exploit the fact that given rationality in the marketplace the effects of an event will be reflected immediately in security prices thus the impact can be measured by examining security prices surrounding the event in this paper event study methods are described including some of the potential complications an example is included to illustrate the approach
