regulation with 20 20 hindsight least cost rules and variable costs regulators sometimes review a regulated firm s input decisions in retrospect i e with 20 20 hindsight and punish bad outcomes rather than bad decisions when such practices are applied consistently to contracts for variable factors in a regime with profit regulation the firm increases its capital stock and relies more heavily on spot market purchases for its variable inputs the firm s profits are reduced but welfare effects on consumers are ambiguous if applied as a type of stochastic price cap regulation however hindsight review can induce variable input choices that minimize expected costs copyright 1992 by blackwell publishing ltd

intraindustry structure and the ease of strategic change there has been considerable recent work in industrial organization emphasizing the importance of group stratification within industries the thrust of this literature is that in empirical work and in particular in investigating public policy problems differences across firms within an industry may be crucial this paper is intended as a contribution to the empirical literature of group structures in this paper i examine patterns of strategic group membership in a number of industries and analyze changes in the strategies used by firms in particular i provide a series of rather simple exploratory tests of the importance of intraindustry strategic differences in a number of industries

beauty and the labor market the authors examine the impact of looks on earnings using interviewers ratings of respondents physical appearance plain people earn less than average looking people who earn less than the good looking the plainness penalty is 5 to 10 percent slightly larger than the beauty premium effects for men are at least as great as for women unattractive women have lower labor force participation rates and marry men with less human capital better looking people sort into occupations where beauty may be more productive but the impact of individuals looks is mostly independent of occupation suggesting the existence of pure employer discrimination copyright 1994 by american economic association

assessing organizational fitness on a dynamic landscape an empirical test of the relative inertia thesis this paper proposes an empirical framework for evaluating the relative structural inertia hypothesis a central assumption of organizational ecology theories in stark contrast to the tenets of strategic management the relative inertia thesis claims that organizations are typically unable to match structural changes to their competitive environments in a timely fashion the hypothesis is tested for the hospital industry in california during the 1980 90 time frame strategic movements in a competition landscape are tracked using a variant of the jaccard similarity coefficient which has been applied in numerous studies of biological competition findings indicate that few hospitals are able to overcome inertial forces in adapting their service portfolios furthermore the ability of hospitals to strategically reposition themselves decreases markedly with provider density analyses also investigate the relation between organizational attributes e g age size mission and portfolio scope and adaptability implications for both ecological and strategic theory are pursued 1997 john wiley sons ltd

what happens to diet and child health when migration splits households evidence from a migration lottery program the impact of migration on food security and child health is likely to differ depending on whether children themselves migrate or whether they remain behind while other household members migrate however existing studies have not been able to examine how impacts differ in these two scenarios because parallel data are required for both the sending and receiving country moreover self selection into migration makes unbiased estimation of either impact difficult we overcome these problems by using a unique survey of tongan households that applied to migrate to new zealand through a migrant quota which selects households through a random ballot this survey covers both migrant children in new zealand and non migrant children in tonga with the migration policy rules providing a source of exogenous variation for identifying impacts our estimates of short run impacts show that diets diverge upon migration children who migrate experience improvements while diets worsen for children who remain there is also suggestive evidence of a divergence in health outcomes with increases in weight for age and height for age found for migrant children and decreases found for children who remain behind while other household members migrate

longitudinal studies of human growth and health a review of recent historical research longitudinal studies of health this paper reviews recent literature using stature and weight as measures of human welfare with a particular interest in cliometric or historical research we begin with an overview of anthropometric evidence of living standards and the new but fast growing field of anthropometric history this literature is always implicitly and often explicitly longitudinal in nature we then discuss i systematic empirical research into the relationship between conditions in early life and later life health and mortality and ii historical evidence on the relationship between body mass morbidity and mortality we conclude with a discussion of the importance of historical sources and understandings to health economics and population health

stature and the standard of living research on the standard of living now emphasizes alternatives or supplements to the national income accounts this paper reviews the results of two decades of research using stature as a measure of health aspects of human welfare after comparing and contrasting stature with per capita income i consider height patterns discovered by economic historians that challenge traditional beliefs about the past including long term trends cycles in heights and the dreadfully small stature of slave children that was followed by catch up growth the paper concludes with comparisons to work in development economics and suggestions for research

measuring the distribution of material well being u s trends abstract economists with a few exceptions have automatically assumed that the important measure of well being is income in contrast economic historians have broadened the measure of well being with particular interest in mortality morbidity nutrition education and leisure when one takes this broader view of the standard of living there appears to be a strong trend toward more equality in the distribution of well being since the industrial revolution gini coefficients calculated for the distributions of lifespan and educational attainment have declined dramatically since the mid nineteenth century for the united states mortality and educational differentials have also declined inequality of leisure time and consumption though not as consistently measured also show trends toward equality over the twentieth century these trends toward equality in well being as measured by indicators other than income and wealth seem to be generated by provision of public goods natural boundaries to lifespan educational attainment and leisure and by the growth in mean per capita income the divergent trends in the distributions of income and the other measures of well being caution against reliance on the distribution of income to interpret trends in inequality

the importance of noncognitive skills lessons from the ged testing program it is common knowledge outside of academic journals that motivation tenacity trustworthiness and perseverance are important traits for success in life thomas edison wrote that genius is 1 percent inspiration and 99 percent perspiration most parents read the aesop fable of the tortoise and the hare to their young children at about the same time they read them the story of the little train that could numerous instances can be cited of high iq people who failed to achieve success in life because they lacked self discipline and low iq people who succeeded by virtue of persistence reliability and self discipline the value of trustworthiness has recently been demonstrated when market systems were extended to eastern european societies with traditions of corruption and deceit it is thus surprising that academic discussions of skill and skill formation almost exclusively focus on measures of cognitive ability and ignore noncognitive skills the early literature on human capital e g gary becker 1964 contrasted cognitive ability models of earnings with human capital models ignoring noncognitive traits entirely the signaling literature e g michael spence 1974 emphasized that education was a signal of a one dimensional ability usually interpreted as a cognitive skill most discussions of ability bias in the estimated return to education treat omitted ability as cognitive ability and attempt to proxy the missing ability by cognitive tests most assessments of school reforms stress the gain from reforms as measured by the ability of students to perform on a standardized achievement test widespread use of standardized achievement and ability tests for admissions and educational evaluation are premised on the belief that the skills that can be tested are essential for success in schooling a central premise of the educational testing movement since its inception much of the neglect of noncognitive skills in analyses of earnings schooling and other lifetime outcomes is due to the lack of any reliable measure of them many different personality and motivational traits are lumped into the category of noncognitive skills psychologists have developed batteries of tests to measure noncognitive skills e g robert sternberg 1985 these tests are used by companies to screen workers but are not yet used to ascertain college readiness or to evaluate the effectiveness of schools or reforms of schools the literature on cognitive tests ascertains that one dominant factor g summarizes cognitive tests and their effects on outcomes no single factor has yet emerged to date in the literature on noncognitive skills and it is unlikely that one will ever be found given the diversity of traits subsumed under the category of noncognitive skills studies by samuel bowles and herbert gintis 1976 rick edwards 1976 and roger klein et al 1991 demonstrate that job stability and dependability are traits most valued by employers as ascertained by supervisor ratings and questions of employers although they present no direct evidence on wages and educational t discussants susan mayer university of chicago cecilia rouse princeton university nan maxwell california state university hayward janet currie university of california los angeles

productivity health and inequality in the intrahousehold distribution of food in low income countries a model is formulated incorporating linkages among nutrition labor market productivity health heterogeneity and the intrahousehold distribution of food and work activities in a subsistence economy empirical results based on a sample of households from bangladesh indicate that despite considerable intrahousehold disparities in calorie consumption households are averse to inequality furthermore consistent with the model the results also indicate that both the higher level and greater variance in the calories consumed by men relative to women reflect in part the greater participation by men in activities in which productivity is sensitive to health status copyright 1990 by american economic association

from the cradle to the labor market the effect of birth weight on adult outcomes lower birth weight babies have worse outcomes both short run in terms of one year mortality rates and longer run in terms of educational attainment and earnings however recent research has called into question whether birth weight itself is important or whether it simply reflects other hard to measure characteristics by applying within twin techniques using an unusually rich dataset from norway we examine the effects of birth weight on both short run and long run outcomes for the same cohorts we find that birth weight does matter despite short run twin fixed effects estimates that are much smaller than ols estimates the effects on longer run outcomes such as adult height iq earnings and education are significant and similar in magnitude to ols estimates

affluence and food a simple way to infer incomes accurate and timely measures of cross country real incomes are still a rarity as the share of expenditure devoted to food is readily available we use engel s law in reciprocal form to measure affluence analysis of real income data for over 100 countries indicates that this approach is viable to recognize the role of uncertainty in the analysis we present the results in the form of stochastic cross country income comparisons

a time to grow and a time to die growth and mortality of credit unions in new york city 1914 1990 one vision of organizational evolution suggests that old and large organizations become increasingly dominant over their environment a second suggests that as organizations age they become less able to respond to new challenges in this article the authors investigate which of these visions best characterizes the evolution of state chartered credit unions in new york city from 1914 through 1990 by analyzing the effects of organizational age size and population density on rates of organizational failure and growth the authors find evidence that old and small institutions are more likely to fail while young and small organizations have the highest growth rates

stature skills and adult life outcomes evidence from indonesia abstractwe investigate the effect of height on earnings occupational choices and a subjective measure of wellbeing among indonesian men we explore the extent to which height captures the effects of endowments set before entry in the labour market physical and cognitive skills co determined with stature early in life do not explain much of the height earnings premium directly yet human capital more broadly including cognition educational attainment and other factors related to childhood conditions explains around half of the height premium and does so through occupational sorting indeed taller workers tend to have more education and educated workers tend to work in more lucrative occupations that require brain and social skills not brawn the unexplained share of the height earnings premium may reflect a specific role of stature on social interaction labour market advantages or self assurance we also find a height premium in happiness half of which simply accounts for the educational and e

inequality at birth some causes and consequences recent research shows that health at birth is affected by many factors including maternal education behaviors and participation in social programs in turn endowments at birth are predictive of adult outcomes and of the outcomes of future generations exposure to environmental pollution is one potential determinant of health at birth that has received increasing attention a large literature outside of economics advocates for environmental justice and argues that poor and minority families are disproportionately exposed to environmental hazards i provide new evidence on this question showing that children born to less educated and minority mothers are more likely to be exposed to pollution in utero and that white college educated mothers are particularly responsive to changes in environmental amenities i estimate that differences in exposure to toxic releases may explain 6 of the gap in incidence of low birth weight between infants of white college educated mothers and infants of black high school dropout mothers this abstract was borrowed from another version of this item

will developing country nutrition improve with income a case study for rural south india aggregate estimates of food expenditure are consistent with such a possibility implying income expenditure elasticities close to one however the high degree of aggregation at which such estimates are made means that the considerable increase in price per nutrient as income increases is ignored and the nutrient elasticities are therefore overstated estimates for a rural south indian sample indicate that this bias is considerable and that the true nutrient elasticities with respect to income may be close to zero

blowing up money the earnings penalty of smoking in the 1970s and the 21st century abstract we analyze the earnings penalty of smoking among swedish twins in two social contexts the 1970s when smoking was common and widely accepted and when there were relatively few tobacco laws aiming to reduce smoking and the 2000s when smoking had become more expensive stigmatizing and less common and when tobacco laws and regulations had intensified the results show that the short term earnings penalty of smoking was much higher in the 21st century than in the 1970s for men for women smokers had on average higher annual earnings compared to nonsmokers in the 1970s but lower annual earnings in the 2000s in the long run there was an earnings gap for men between never smokers and continuous smokers whereas there was a pronounced earnings bonus of smoking cessation for women the results emphasize the importance of social context and the long term horizon when evaluating the consequences of smoking for earnings

life cycle variations in the association between current and lifetime income replication and extension for sweden we apply haider and solon s generalized errors in variables model to swedish income tax data to produce estimates of the association between current and lifetime income our estimates demonstrate strong life cycle patterns this implies that the widespread use of current income as a proxy for lifetime income leads to inconsistent parameter estimates i e life cycle bias even when the proxy is used as the dependent variable estimates for comparable cohorts of swedish and american men demonstrate surprising similarities there are however significant gender and cohort differences in this association that lead to statistically significant and quantitatively meaningful differences in life cycle biases

wage gains associated with height as a form of health human capital height is consulted as a latent indicator of early nutrition and lifetime health status height is observed to increase in recent decades in populations where per capita national income has increased and public health activities have grown height is determined by genetic make up and realized in part through satisfactory nutrition and health related care and conditions alternative instrumental variables iv are explored which proxy price and income constraints which are expected to influence the latter reproducible human capital investments in height i report ols and iv estimates of the partial effect of height on log hourly wages in recent national surveys from three countries ghana brazil and the united states i conclude that the human capital productivity effect of height estimated by parent education ivs in the us and ghana are many times larger than the ols estimates and in ghana and brazil the regional price ivs estimates also imply a substantially larger human capital wage effects of height compared with the ols estimates the ols estimates of height effects on wages are dominated by the genetic variation in height and appear to understate substantially the human capital returns to health and nutrition inputs which increase adult height this abstract was borrowed from another version of this item

regulation with 20 20 hindsight heads i win tails you lose regulators are commonly accused of using 20 20 hindsight to punish a firm for bad outcomes rather than bad decisions it is often thought that such penalties lead to underinvestment by the firm i find that this expectation is not borne out when retrospective review is based on the firm s avoided costs in a joskow type model hindsight review mitigates the firm s tendency to build oversized risky projects moving the firm closer to the cost minimizing level of investment in a rate of return model the firm s allowed rate of return may have to be increased to keep expected profits nonnegative if this is done hindsight review does not affect the firm s investment level but it does correct the risk neutral firm s tendency to pay an excessive premium to eliminate construction cost uncertainty

the ethnic employment and income gap in sweden is skill or labor market discrimination the explanation this study uses a cognitive test score the swedish military enlistment test taken at age 18 to identify whether the ethnic employment and income gap in sweden is caused by a pre market skill gap and or ethnic discrimination the employment gap and income gap are estimated for males born in sweden with different ethnic backgrounds their parents were born in sweden or in southern europe or outside europe controlling for the cognitive test score does not affect the ethnic employment gap and for incomes the ethnic income gap almost disappears

the effect of adolescent experience on labor market outcomes the case of height taller workers receive a wage premium net of differences in family background the disparity is similar in magnitude to the race and gender gaps we exploit variation in an individual s height over time to explore how height affects wages controlling for teen height essentially eliminates the effect of adult height on wages for white men the teen height premium is not explained by differences in resources or endowments the teen height premium is partially mediated through participation in high school sports and clubs we estimate the monetary benefits of a medical treatment for children that increases height

demand uncertainty and the regulated firm in this paper we investigate the impact of demand uncertainty on the choice of plant capacity by a regulated firm over the past few years demand uncertainty has become a major element in the decision making of utilities and particularly in their decision making with respect to capacity choices in a recent study by sri 1977 it was reported that to maximize expected consumers surplus more generating capacity was required for the electric utility industry when operating under demand uncertainty than under demand certainty 1 this finding raises the question whether the structure of rate regulation of electric utilities provides the appropriate incentives for them to invest in more capacity under demand uncertainty then under certainty the present paper addresses such questions the model of the regulated firm that is employed in this paper derives from the work of joskow 1974 concerning the recent history of rate regulation in the electric utility industry briefly joskow reported that during the 1960s and the early 1970s the impetus for rate reviews in the electric utility industry came mainly from the utilities and not from the public utility commissions puc s joskow s findings are corroborated by data for the period 1948 1978 a study of all rate cases involving electric utilities in the u s for that period shows that of a total of 363 cases 350 of these were instances of utility initiated rate reviews and only 13 were cases of puc initiated reviews 2 from the point of view of the formal theory of the regulated firm this strongly suggests that the averch johnson model of a firm operating at or near an allowed rate of return constraint with the allowed rate of return being in excess of the cost of capital to the firm should be replaced by a model of price regulation in which attention is shifted to the non negativity of profits constraint or at least this should be done with respect to the electric utility industry with some elaborations this is basically what we do in this paper building on the approach adopted in a recent paper on a related topic 3

after minimalism transformations of state bar associations from market dependence to state reliance 1918 to 1950 compared to conventional approaches we conceptualize transformations in populations of organizations in terms of shifts in their relative embeddedness in markets and states as organizations expand beyond minimalist conditions of existence states and markets offer alternative solutions to the core problems of persistence obtaining resources managing competition and constructing legitimacy by analyzing the movers and stayers in a population of state bar associations that split into two co existing forms of organization one primarily reliant on the market and the other primarily dependent on the state we demonstrate that a two stage transition to a new form can be explained by the complementary interplay of resource dependency and neo institutional theories organizations are more likely to move from reliance on the market to reliance on the state if 1 their market performance has been unsuccessful 2 states are willing and able to solve organizational problems 3 organizations are younger and less established and 4 compelling alternative models have been propagated by moral entrepreneurs and adopted by influential states

height and earnings the role of cognitive and noncognitive skills we use large scale register data on 450 000 swedish males who underwent mandatory military enlistment at age 18 and a subsample of 150 000 siblings to examine why tall people earn more we show the importance of both cognitive and noncognitive skills as well as family background and muscular strength for the height earnings relationship in addition we show that a substantial height premium remains after these factors have been accounted for which originates from very short people having low earnings this is mostly explained by the sorting of short people into low paid occupations which may indicate discrimination by stature

an ecological analysis of competition among us communities we apply the ecological concept of the organization s niche pioneered by john freeman and mike hannan to the study of geographic communities we define a community s market niche by the ties linking a community to the industries on which it depends for growth we then hypothesize that the extent to which a community s market niche is occupied by other communities is a source of constraint and opportunity depending on the geographical locations of the communities that occupy the same market niche geographically distant communities occupying similar market niches are hypothesized to experience primarily constraint arising from competition for opportunities of exchange geographically proximate communities occupying similar market niches are hypothesized to face constraint arising from competition for exchange opportunities as well as opportunity arising from access to valuable resources associated with the existence of similar others empirical analyses of firm foundings and exits across us communities support these hypotheses implications of our findings for ecological research on the niche and for the literature on communities are discussed copyright 2012 the author 2011 published by oxford university press on behalf of associazione icc all rights reserved oxford university press

frequent incremental change organizational size and mortality in high technology competition while radical technological change is often characterized as hazardous particularly to incumbents incremental technological change has appeared to be immune from such risks little attention has been given to the possibility that under some circumstances incremental technological change can be quite risky this article argues that there may be tradeoffs to high rates of incremental technological change the costs are of two kinds the organizational disruptions associated with frequent technological change and overestimating the advantages and receptiveness of the technological improvement we argue that larger firms are better equipped than smaller firms to cope with these costs and will reap greater benefits from incremental changes using data on the population of worldwide floppy disk drive manufacturers we find that frequent incremental technical changes decrease organizational mortality for large firms but increase it for smaller firms we also find that large firms that frequently introduce incremental technological improvements are more potent competitors this study helps us understand how frequent incremental change affects mortality as organizations grow advice to managers to engage in continuous incremental innovation can therefore be misguided because unless firms are large they may incur costs that are so great that the firm actually fails by innovating frequently copyright 2010 the author 2009 published by oxford university press on behalf of associazione icc all rights reserved oxford university press

accounting for the effect of health on economic growth i use microeconomic estimates of the effect of health on individual outcomes to construct macroeconomic estimates of the proximate effect of health on gdp per capita i employ a variety of methods to construct estimates of the return to health which i combine with cross country and historical data on height adult survival rates and age at menarche using my preferred estimate eliminating health differences among countries would reduce the variance of log gdp per worker by 9 9 percent and reduce the ratio of gdp per worker at the 90th percentile to gdp per worker at the loth percentile from 20 5 to 17 9 while this effect is economically significant it is also substantially smaller than estimates of the effect of health on economic growth that are derived from cross country regressions

the contribution of early life versus labour market factors to intergenerational income persistence a comparison of the uk and sweden we explore whether differences in intergenerational income mobility between the uk and sweden show up early in life finding stronger associations between parental income and birthweight height and school performance in the uk we investigate whether these differentials can account for the country difference in income mobility while differences in the associations in birthweight and height are too weak to matter school performance does account for a substantial part of this difference however country differences in the earnings returns to these skills are at least as important as the differences in the link between parental income and skills

height health and inequality the distribution of adult heights in india this paper explores the relationship between adult heights and the distribution of income across populations of individuals there is a long literature that examines the relationship between mean adult heights and living standards if adult height is set by the balance between food intake and charges to disease in early childhood it is informative about economic and epidemiological conditions in childhood because taller populations are better off more productive and live longer the relationship between childhood conditions and adult height has become an important focus in the study of the relationship between health and wealth here i follow one of the tributaries of this main stream a relationship between income and height at the individual level has implications for the effects of income inequality on the distribution of heights these relationships parallel but are somewhat more concrete than the various relationships between income inequality and health that have been debated in the economic and epidemiological literatures richard g wilkinson 1996 angus deaton 2003 if height is an increasing but concave function of income average height will be negatively related to income inequality richard steckel 1995 income inequality will also have implications for the dispersion of height so that inequality in height might serve as an indicator of inequality of income in the absence of data on the latter just as mean height might serve as an indicator of mean income aravinda m guntupalli and joerg baten 2006 and alexander moradi and baten 2005 differences in height between subpopulations such as lords and vassals or highlanders and lowlanders may also provide information on the distribution of resources between such subpopulations carles boix and frances rosenbluth 2006 in section 2 below i present a theoretical discussion of what to expect in section 3 i provide an analysis of adult heights in india where i can look at the relationship across states between a mean heights and expenditure inequality b inequality in height and expenditure inequality c men s and women s heights the difference in heights between men and women is of considerable importance in its own right india has one of the highest rates of child malnutrition in the world with around 55 percent of young children stunted a leading explanation for this is health discrimination against women vulimiri ramalingaswami urban jonsson and jon rohde 1996 if discrimination starts in early childhood and since all evidence suggests that there are regional differences in the treatment of women there should be clear traces in spatial patterns of relative heights between men and women
