modelling seasonality in residential water demand the case of tunisia this article proposes to model seasonal patterns of residential water demand using the techniques of seasonal integration and cointegration the methodology is applied to quarterly aggregate time series data for tunisia 1980 2007 applying the same increasing multi step pricing scheme in the whole country first a seasonal cointegration analysis demonstrates the relevance of a pricing policy that increases the size of the lower consumption block in summer second the nonseasonal cointegration analysis reveals a relatively high price elasticity for the highest consumption block therefore we also propose to increase the tariff progressivity to promote water savings this modified pricing scheme will help to achieve goals of environmental protection and social equity

is there a glass ceiling in sweden using 1998 data we show that the gender log wage gap in sweden increases throughout the wage distribution and accelerates in the upper tail we interpret this as a strong glass ceiling effect we use quantile regression decompositions to examine whether this pattern can be ascribed primarily to gender differences in labor market characteristics or in the rewards to those characteristics even after extensive controls for gender differences in age education both level and field sector industry and occupation we find that the glass ceiling effect we see in the raw data persists to a considerable extent

the structure of the female male wage differential is it who you are what you do or where you work the efficacy of policies to narrow the malelfemale wage differential depends partly on the size of the portion s of the gap targeted previous research finds no between sex wage gap within occupations within employer job cell this is the first study to disentangle segregation by occupation from that based on employer or on job cell in five industries controlling for other forms of segregation occupational segregation produces a gap of 11 percent manufacturing to 26 percent services the wage gaps from establishment and job cell segregation are about 6 percent each since comparable worth acts on the occupation and job cell components it has a potentially large impact

distributional impacts of state level energy efficiency policies in regional electricity markets abstract a number of u s states have passed legislation targeting energy efficiency and peak demand reduction we study one such state pennsylvania within the context of pjm a regional electricity market covering numerous different states our focus is on the distributive impacts of this policy specifically how the policy is likely to impact electricity prices in different areas of pennsylvania and in the pjm market more generally such spatial differences in policy impacts are difficult to model and the transmission system is often ignored in policy studies our model estimates supply curves on a zonal basis within regional electricity markets and yields information on price and fuel utilization within each zone we use the zonal supply curves estimated by our model to study regional impacts of energy efficiency legislation on utilities both inside and outside of pennsylvania for most utilities in pennsylvania it would reduce the influence of natural gas on electricity price formation and increase the influence of coal it would also save 2 1 to 2 8 percent of total energy cost in pennsylvania in a year similar to 2009 the savings are lower than 0 5 percent in other pjm states and the prices may slightly increase in washington dc area

flexible demand and supply as enablers of variable energy integration abstract this article analyses the impact of the interplay between the demand response wind penetration and hydropower in the nordic power market long term equilibrium model is developed in which the thermal power capacity adjusts to the zero profit level over varying real time pricing adoption rates and wind power shares the results show that an increased demand response decreases the amount of thermal power capacity and improves the utilization rate of thermal power and the value of wind power there is a decreasing marginal gain from an increasing demand response adoption with respect to the thermal utilization and wind value factor however the demand response itself does not lead to lower co2 emissions or reduced variation in hydropower generation

belief flipping in a dynamic model of statistical discrimination abstract the literature on statistical discrimination shows that ex ante identical groups may be differentially treated in discriminatory equilibria this paper constructs a dynamic model of statistical discrimination and explores what happens to the individuals who nonetheless overcome the initial discrimination if an employer discriminates against a group of workers in her initial hiring she may actually favor the successful members of that group when she promotes from within the firm the worker s welfare implications i e who benefits from an employer s discriminatory hiring practices are unclear even though agents face discrimination initially some may be better off because of it

racial discrimination in the labor market theory and empirics we review theories of race discrimination in the labor market taste based models can generate wage and unemployment duration differentials when combined with either random or directed search even when strong prejudice is not widespread but no existing model explains the unemployment rate differential models of statistical discrimination based on differential observability of productivity across races can explain the pattern and magnitudes of wage differentials but do not address employment and unemployment at their current state of development models of statistical discrimination based on rational stereotypes have little empirical content it is plausible that models combining elements of the search models with statistical discrimination could fit the data we suggest possible avenues to be pursued and comment briefly on the implication of existing theory for public policy jel j15 j31 j64 j71

price elasticity of groundwater demand attenuation and amplification bias due to incomplete information measurement errors in both human and natural components of agricultural and environmental systems can be as much a source of estimation bias as omitted variables selfselection simultaneity and reverse causality nonetheless partly because of difficulties in obtaining data there is less literature on measurement error problems than on other endogeneity problems this article examines estimation bias in the price elasticity of groundwater consumption for irrigated agriculture on the intensive margin the price at issue is for the energy used in pumping and pressurizing water for delivery lacking the precise unit irrigation cost previous studies imputed irrigation costs we first consider groundwater irrigation costs and identify factors that can cause measurement errors in the process of imputation under incomplete information about the determinants of irrigation costs we follow this by systematically analyzing the potential bias caused by measurement errors using econometric theory along with monte carlo simulations where appropriate we then quantify actual measurement errors making use of a unique dataset in which energy and groundwater consumption data are matched for individual observations finally we compare regression results using exact irrigation costs as opposed to imputed ones we find evidence of substantial measurement errors resulting in attenuation and amplification bias in the price elasticity of irrigation water consumption on the intensive margin our results indicate that measurement errors in irrigation costs can lead to misleading policy implications related to water and energy pricing as a tool to conserve water we also show that estimating the energy price elasticity of groundwater use is not as straightforward as previously thought

responses to changes in domestic water tariff structures a latent class analysis on household level data from granada spain a problem that affects the estimation of water demand functions is the presence of unobserved individual heterogeneity which means that a common demand function is unlikely to represent the behavior of all users we implement latent class models to estimate water demand functions for four groups of users who are classified according to their unobservable preferences this more flexible approach makes it possible to distinguish four different response patterns to changes in the drivers of water use including different price elasticities these results should be of particular interest to regulators who would like to tailor water demand management policy to heterogeneous users our analysis exploits household level panel data on residential water demand and consumers characteristics obtained by combining information from a survey of 1 465 domestic users in the city of granada and bimonthly price and consumption data supplied by this city s water supplier from the period 2009 2011

demand side management policies for residential water use who bears the conservation burden to assess the potential for urban demand side management dsm policies as a water resource management tool we analyze the extent to which price and alternative policy instruments such as use and quantity restrictions and subsidies for water efficient technologies reduce residential demand and their distributional implications by type of household using detailed household level panel data for two california communities the results suggest that the ultimate effects of dsm policies in terms of the reduction in aggregate demand and distribution of water savings among household classes depend both on the policy instrument selected and the composition of aggregate demand

cross country evidence for social dimensions of urban water consumption during droughts a systematic literature review is carried out to understand the social dimensions driving the adoption of water saving behaviors in urban households salient aspects of the problem correspond to price elasticity of water demand citizens awareness of water value and water conservation intentions the management of which is generally tackled through water price and non price approaches however the evidence falls short to explain the social drivers and inhibitors of stable water consumption reductions after reviewing 65 papers documenting research conducted in north america australia united kingdom middle east mexico china and japan a series of categories of analysis drawn from the literature are introduced as the social factors that influence water conservation reduction although the brink of the state of the art mentions the existence of an intention behavior gap sustainability requires further aspirations than short term water consumption reduction by households the long term challenges of sustainability require the understanding of intention behavior stable reduction gaps further research is needed to fill this double gap understanding the determinants and insights behind the dissipation or stabilization of water consumption reductions through time are certainly rich areas of analysis for the social sciences

is there a glass ceiling over europe exploring the gender pay gap across the wages distribution using harmonised data from the european union household panel we analyse gender pay gaps by sector across the wages distribution for ten countries we find that the mean gender pay gap in the raw data typically hides large variations in the gap across the wages distribution we use quantile regression qr techniques to control for the effects of individual and job characteristics at different points of the distribution and calculate the part of the gap attributable to differing returns between men and women we find that first gender pay gaps are typically bigger at the top of the wage distribution a finding that is consistent with the existence of glass ceilings for some countries gender pay gaps are also bigger at the bottom of the wage distribution a finding that is consistent with sticky floors third the gender pay gap is typically higher at the top than the bottom end of the wage distribution suggesting that glass ceilings are more prevalent than sticky floors and that these prevail in the majority of our countries fourth the gender pay gap differs significantly across the public and the private sector wages distribution for each of our eu countries

incentives to water conservation under scarcity comparing price and reward effects through stated preferences abstract focusing on two different european institutional contexts a stated preference approach is adopted to elicit the willingness to save water under three alternative incentive policies a water price increase monetary reward and symbolic prize in addition two water scarcity scenarios a critical and a regular scenario are devised to analyze how information on water scarcity moderates the effect of incentives empirical results show that users become sensitive to monetary incentives while they remain insensitive to non monetary ones when water is scarce batteries of pre tests on the sample and robustness checks on the results strengthen the reliability of our findings and partially circumvent concerns related to the use of a stated preference approach the study adds to the literature on the efficacy of economic incentives in the water sector and the role of local factors in explaining water users response

learning from coarse information biased contests and career profiles an organization s promotion decision between two workers is modelled as a problem of boundedly rational learning about ability the decision maker can bias noisy rank order contests sequentially thereby changing the information they convey the optimal final period bias favours the leader reinforcing his likely ability advantage when optimally biased rank order information is a sufficient statistic for cardinal information the leader is favoured in every period in other environments bias in early periods may i favour the early loser ii be optimal even when the workers are equally rated and iii reduce the favoured worker s promotion chances this paper presents a model of boundedly rational learning by an organization the aims are to represent in a simple form the costs of gathering processing or transmitting information and to analyse their implications for the procedures selected to handle information as well as for the decisions actually made like other recent work on the internal organization of firms this work explores to what extent organizational structure and behaviour as well as organizational performance can be explained by adaptation to the costs associated with information in the learning model we formulate the decision maker not only selects a rule specifying what action to take as a function of his observations but also chooses sequentially the information partitions generating those observations this general problem is interpreted in the context of an organization which needs to make an important promotion decision and which attempts to maximize the value of the information generated during the observation periods that precede the decision one of the motivations for this analysis was the finding by organizational sociologists that earnings and promotions in the later stages of a worker s career are strongly correlated with earnings and promotions in the early stages kanter 1977 rosenbaum 1984 later success is positively associated with early success even when one controls for the effect of observable characteristics likely to affect performance such as education one obvious source of this correlation is differences in ability that persist over time and that are not captured by the observable covariates in this paper we focus on differences in ability which are initially unobservable by organizations and their workers as well as by researchers we present a simple model of an organization trying to learn about differences in ability and show

unequal assignment and unequal promotion in job ladders in this study gender differentials in professional status attainment are analyzed in the theoretical literature unequal treatment of females is often rationalized by their higher probability of quitting to test this hypothesis empirically we use data from the austrian microcensus and find that neither the risk of childbearing nor different productive characteristics can explain the crowding of females in lower hierarchical positions females have to fulfill higher ability standards to be promoted work experience is not rewarded in the same manner as it is for men

mentoring and diversity we study how diversity evolves at a firm with entry level and upper level employees who vary in ability and type gender or ethnicity the ability of entry level employees is increased by mentoring an employ receives more mentoring when more upper level employees have the same type optimal promotions are biased by type and this bias may favor either the minority or the majority we characterize possible steady states including a glass ceiling where the upper level remains less diverse than the entry level a firm may have multiple steady states whereby temporary affirmative action policies have a long run impact

economic potential of demand response at household level are central european market conditions sufficient abstract the aim of this paper is to show the economic potential of demand response dr on household level at central european market conditions thereby required economic benefits for consumers participation the realistic load shifting potential at household level and the estimation of essential intelligent infrastructure costs are discussed the core of this paper builds a case study applying spot market oriented load shifting from the supplier s point of view by using austrian electricity market data household load profiles as well as a heat pump and e car charging load profile it is demonstrated which cost savings for suppliers can be derived from such load shifting procedure at household level furthermore upper cost limits for intelligent infrastructure in order to break even are derived results suggest to take a critical look at european discussions on dr implementation on household level showing that at central european market conditions the potential for dr at household level is restricted to significant loads and hence the applied load shifting strategy is only beneficial with application to heat pumps in contrast the frequently discussed shifting of conventional household devices loads such as washing machines economically does not add up

assortative marriage and the effects of government homecare subsidy programs on gender wage and participation inequality we develop a model of the labor market where firms incur an adjustment cost when one of their workers quits and males and females form households assortatively by skill we show how this environment can lead to an economy where females earn less and drop out more frequently than equally skilled males in equilibrium even when males and females constitute ex ante identical populations we then examine how different government homecare subsidy schemes may affect such gender inequality in the labor market we show that the effect of government homecare subsidy schemes on gender inequality depends crucially on the form in which the subsidy is given and to whom it is allocated

an evaluation of the welfare effects of reducing energy subsides in iran abstract energy prices in iran have traditionally been heavily subsidized by the government and as a result energy consumption per capita in iran is close to the european union level the welfare effects of efforts to raise energy prices closer to world levels are examined in this paper reform of energy prices is an important element of the economic reform plan 2010 2014 for iran we first analyze the relationship between energy consumption energy and non energy prices by estimating the household expenditure function the results show that a higher energy prices will decrease energy consumption by iranian households second we evaluate the impact of a rise of energy prices on the household welfare by measuring the compensating variation cv in five steps with a compensating payment the results show that iranian household welfare will increase with a 100 or 200 rise in energy prices if the government pays 20 30 or 50 of the 20 billion income resulting from removing energy subsidies while in contrast iranian household welfare will decrease with a 400 and 500 rise in energy prices if the government payment is 20 or 30 of 20 billion income

benefits and challenges of electrical demand response a critical review advances in it control and forecasting capabilities have made demand response a viable and potentially attractive option to increase power system flexibility this paper presents a critical review of the literature in the field of demand response providing an overview of the benefits and challenges of demand response these benefits include the ability to balance fluctuations in renewable generation and consequently facilitate higher penetrations of renewable resources on the power system an increase in economic efficiency through the implementation of real time pricing and a reduction in generation capacity requirements nevertheless demand response is not without its challenges the key challenges for demand response centre around establishing reliable control strategies and market frameworks so that the demand response resource can be used optimally one of the greatest challenges for demand response is the lack of experience and the consequent need to employ extensive assumptions when modelling and evaluating this resource this paper concludes with an examination of these assumptions which range from assuming a fixed linear price demand relationship for price responsive demand to modelling the highly diverse distributed and uncertain demand response resource as a single centralised negative generator adopting fixed characteristics and constraints

an empirical survey of residential water demand modelling abstract the increased reliance on demand side management policies as an urban water consumption management tool has stimulated considerable debate among economists water utility managers regulators consumer interest groups and policymakers in turn this has fostered an increasing volume of literature aimed at providing best practice estimates of price and income elasticities quantifying the impact of non price water restrictions and gauging the impact of non discretionary environmental factors affecting residential water demand this paper provides a synoptic survey of empirical residential water demand analyses conducted in the last 25 years both model specification and estimation and the outcomes of the analyses are discussed

household adoption of water efficient equipment the role of socio economic factors environmental attitudes and policy using survey data of around 10 000 households from 10 oecd countries we identify the driving factors of household adoption of water efficient equipment by estimating probit models of a household s probability to invest in such equipment the results indicate that environmental attitudes and ownership status are strong predictors of adoption of water efficient equipment in terms of policy we find that households that were both metered and charged for their water individually had a much higher probability to invest in water efficient equipment compared to households that paid a flat fee

iso net surplus collection and allocation in wholesale power markets under lmp this study uses five bus and 30 bus test cases to explore iso net surplus congestion rent collections and allocations in wholesale power markets with grid congestion managed by locational marginal prices lmps price sensitivity of demand and generator learning capabilities are taken as experimental treatment factors a key finding is that conditions resulting in greater generator capacity withholding hence higher and more volatile lmps also result in greater iso net surplus collections that can be substantial in size a key conclusion is that iso net surplus collections should be used pro actively to mitigate the conditions encouraging generator capacity withholding and hence high and volatile lmps rather than to provide ex post support for lmp payment offsets and lmp volatility risk hedging as is currently the norm

an economic welfare analysis of demand response in the pjm electricity market abstract we analyze the economic properties of the economic demand response dr program in the pjm electricity market in the united states using dr market data pjm s program provided subsidies to customers who reduced load in response to price signals the program incorporated a trigger point at a locational marginal price of 75 mwh at or beyond which payments for load reduction included a subsidy payment particularly during peak hours such a program saves money for the system but the subsidies involved introduce distortions into the market we simulate demand side bidding into the pjm market and compare the social welfare gains with the subsidies paid to price responsive load using load and price data for year 2006 the largest economic effect is wealth transfers from generators to non price responsive loads based on the incentive payment structure that was in effect through the end of 2007 we estimate that the social welfare gains exceed the distortions introduced by the subsidies lowering the trigger point increases the transfer from generators to consumers but may result in the subsidy outweighing the social welfare gains due to load curtailment we estimate that the socially optimal range for the incentive trigger point would be 66 77 mwh

demand and distributional effects of water pricing policies abstract worldwide water scarcity threatens delivery of water to urban centers water pricing is often recommended to reduce demand in this paper demand and distributional effects of water pricing policies are examined in a block pricing model that is applied to the metropolitan region of sao paulo water demand functions are estimated using marginal and average price models based on monthly data for the period 1997 2002 price elasticities of water demand range between 0 45 and 0 50 and income elasticities between 0 39 and 0 42 for the current combined regressive progressive block price system the poor spend almost 4 2 to 4 7 of their income on water the rich only pay 0 4 to 0 5 of their income whereas they consume more than twice as much a progressive block price or an income dependent price system may result in a more equalized income distribution however the analysis shows that there is a trade off between a more equalized income distribution and revenues earned by the water company more pro poor pricing systems may result as well in lower revenues for the water company

are emily and greg more employable than lakisha and jamal a field experiment on labor market discrimination we study race in the labor market by sending fictitious resumes to help wanted ads in boston and chicago newspapers to manipulate perceived race resumes are randomly assigned african american or white sounding names white names receive 50 percent more callbacks for interviews callbacks are also more responsive to resume quality for white names than for african american ones the racial gap is uniform across occupation industry and employer size we also find little evidence that employers are inferring social class from the names differential treatment by race still appears to still be prominent in the u s labor market jel j71 j64

will affirmative action policies eliminate negative stereotypes a key question concerning affirmative action is whether the labor market gains it brings to minorities can continue without it becoming a permanent fixture in the labor market the authors argue that this depends on how the policy affects employers beliefs about the productivity of minority workers they study the joint determination of employer beliefs and worker productivity in a model of statistical discrimination in job assignments the authors prove that even when identifiable groups are equally endowed ex ante affirmative action can bring about a situation in which employers correctly perceive the groups to be unequally productive ex post copyright 1993 by american economic association

measuring welfare losses from interruption and pricing as responses to water shortages an application to the case of seville supply cuts and pricing policies can be used to ration water the appropriateness of a given policy depends on the losses in social welfare which it generates we find some drawbacks with the only method in the previous literature which deals with the issue of measuring welfare losses under supply cuts we propose an alternative method we compare the welfare losses under supply cuts and a pricing policy during the drought period of 1992 1996 in seville spain using both methods and find that the results vary widely from one method to the other

the residential water demand effect of increasing block rate water budgets we investigate the effect of introducing a fiscally neutral increasing block rate water budget price structure on residential water demand we estimate that demand was reduced by around 17 although the reduction was achieved gradually over more than three years as intermediate steps we derive estimates of price and income elasticities that rely only on longitudinal variability we investigate how different subpopulations responded to the pricing change and find evidence that marginal rather than average prices may be driving consumption we also derive alternative rate structures that might have been implemented and assess their estimated demand effects

promotion signaling discrimination and positive discrimination policies this article studies discrimination in a model in which promotions are used as signals of worker ability the model can account for statistical and taste based discrimination in the short run a positive discrimination policy is beneficial for workers in the middle of the ability distribution because these workers are promoted if and only if the policy is in place instead workers of either high or low ability suffer from the policy in the long run the policy benefits all targeted workers the model can explain empirical findings about the effects of a gender quota on the boards of norwegian companies

job discrimination market forces and the invisibility hypothesis the invisibility hypothesis holds that the job skills of disadvantaged workers are not easily discovered by potential new employers but that promotion enhances visibility and alleviates this problem then at a competitive labor market equilibrium firms profit by hiding talented disadvantaged workers in low level jobs consequently those workers are paid less on average and promoted less often than others with the same education and ability as a result of the inefficient and discriminatory wage and promotion policies disadvantaged workers experience lower returns to investments in human capital than other workers

comparing residential water demand estimates under decreasing and increasing block rates using household data using a new model formulation and data from a sample of colorado utilities we investigated the price specification controversy marginal price versus average revenue when estimating residential water demand the improved statistical fit using average

payments or persuasion common pool resource management with price and non price measures we use lab experiments to study policies that address common pool resource overuse we look at a price mechanism specifically a pigouvian subsidy and four non price interventions the non price policies are information alone information with a normative message communication alone and normative messages with communication allowed in all experiment sessions no intervention occurs in the first seven and last seven rounds allowing us to examine the effects of introducing and taking away a policy the subsidy leads to near efficient extraction but surprisingly leads groups that were not over extracting to also reduce extraction this over compliance decreases efficiency although on net the subsidy is the most efficiency enhancing intervention information provision communication normative appeals and normative appeals combined with communication all reduce over extraction though by less than the subsidy without exacerbating over compliance however the effects of information alone and communication alone are small and not robust the non price policies cause a decline in over extraction of from 0 549 information to 11 441 normative appeals with communication these effects are of the same order of magnitude as the effects seen in major field studies of conservation messaging the subsidy has the worst persistence properties after the intervention ceases while normative messages with communication have the best

orchestrating impartiality the impact of blind auditions on female musicians a change in the audition procedures of symphony orchestras adoption of blind auditions with a screen to conceal the candidate s identity from the jury provides a test for sex biased hiring using data from actual auditions in an individual fixed effects framework we find that the screen increases the probability a woman will be advanced and hired although some of our estimates have large standard errors and there is one persistent effect in the opposite direction the weight of the evidence suggests that the blind audition procedure fostered impartiality in hiring and increased the proportion women in symphony orchestras

a language theory of discrimination any advanced industrial society is composed of a number of speech communities with different verbal and nonverbal languages in particular in the united states blacks and whites and men and women have sharply differing methods of speaking and listening this paper develops a model in which people can only work together if they speak the same language and in which it is costly to learn a second language the competitive market will tend to minimize communication through segregation but if interaction is required the cost will be borne by the minority a number of nontrivial predictions are derived from the model

classification of future electricity market prices forecasting short term electricity market prices has been the focus of several studies in recent years although various approaches have been examined achieving sufficiently low forecasting errors has not been always possible however certain applications such as demand side management do not require exact values for future prices but utilize specific price thresholds as the basis for making short term scheduling decisions in this paper classification of future electricity market prices with respect to pre specified price thresholds is introduced two alternative models based on support vector machines are proposed in a multi class multi step ahead price classification context numerical results are provided for classifying prices in ontario s and alberta s markets

promotion signaling gender and turnover new theory and evidence we extend promotion signaling theory to incorporate gender and across firm mobility within and across job levels evidence from worker firm linked finnish panel data supports our theory for some groups controlling for worker performance inferred from performance related pay within firm promotion probabilities are increasing and wage increases from promotion are decreasing in educational attainment for some educational groups with results stronger for first than for subsequent promotions women have lower promotion probabilities than men and a greater sensitivity of promotion probability to educational attainment across firm promotions are rare but bring wage increases exceeding those for internal promotions and across firm lateral moves

second order statistical discrimination abstract the low representation of female workers in elite jobs is sometimes attributed to a tail effect if the human capital distribution exhibits less variation among females than among males then even with comparable average human capital there will be fewer females in the right tail than males this paper offers an explanation for why the human capital distribution might have this property we show that the belief that the female human capital distribution has a lower variance than the male distribution can be self fulfilling in that it provides individuals with incentives to invest in human capital such that the resulting distribution exhibits exactly this characteristic if this happens fewer females are employed in high end jobs a glass ceiling effect the average productivity of female workers may at the same time be higher than that of male workers

pink work same sex marriage employment and discrimination abstract this paper analyzes how the legalization of same sex marriage in the u s affected same sex couples in the labor market by using data from the american community survey access to marriage led to amendments in tax health insurance and adoption laws that could have encouraged some same sex partners to specialize in household production and decrease their labor supply nevertheless estimates from a difference in difference model show that the individual and joint probabilities of being employed increased among same sex couples additional evidence suggests that these changes in employment were driven by improvements in attitudes and lower discrimination against sexual minorities following the introduction of marriage equality

a general equilibrium model of statistical discrimination we study a general equilibrium model with endogenous human capital formation in which ex ante identical groups may be treated asymmetrically in equilibrium the interaction between an informational externality and general equilibrium effects creates incentives for groups to specialize discrimination may arise even if the corresponding model with a single group has a unique equilibrium the dominant group gains from discrimination rationalizing why a majority may be reluctant to eliminate discrimination the model is also consistent with reverse discrimination as a remedy against discrimination since it may be necessary to decrease the welfare of the dominant group to achieve parity

the effect of statistical discrimination on black white wage inequality estimating a model with multiple equilibria this article presents the structural estimation of the parameters of a statistical discrimination model although the model is capable of displaying multiple equilibria an estimation strategy that identifies both the model parameters and the equilibrium selected by the economic agents is developed and empirically implemented a comparison between the selected equilibria and the other potential equilibria reveals that the decline in wage inequality experienced in the u s economy cannot be attributed to changes in the equilibrium selection nonetheless a counterfactual experiment shows that in a color blind society blacks wage would have been on average more than 20 higher

the differing nature of black white wage inequality across occupational sectors the nature of racial wage inequality appears to differ across occupation sectors specifically i find that all of the racial wage inequality in the white collar job sector can be accounted for by controlling for the academic skill level of each worker but almost half of the overall racial wage inequality remains in the blue collar sector after controlling for each worker s academic skill relatedly after controlling for academic skill i find that black workers are actually more likely to work in the white collar sector than white workers i show that these findings are consistent and arguably directly implied by both preference based and statistical based models of discrimination however omitted variable bias and measurement error also cannot be ruled out as possible explanations

sex discrimination in the promotion process previous research has suggested that intra occupational earnings differences are the principal source of the long standing earnings gap between men and women following that line of research this study examines the extent of gender differences in the incidence of and returns to promotions drawing on the quality of employment panel the authors compare the earnings and promotion experience of men and women over the period 1973 1977 after controlling for unmeasured differences in job level and constant individual ability in a fixed effect model they conclude that the returns to promotion are comparable for men and women further analysis indicates however that women are held to higher promotion standards than men and therefore receive fewer promotions than men with equal measured abilities although the female male wage ratio in this sample increased by nearly 6 percent over four years the increase could have been as much as 9 2 percent if women and men had been held to the same promotion standards

how immigrants fare across the earnings distribution in australia and the united states this paper investigates determinants of the earnings distribution for native born workers and immigrant workers in two countries the authors using data from the 2000 u s census and 2001 australian census employ a methodology quantile regression that facilitates measurement of the native born immigrant earnings differential and the partial effect of explanatory variables such as schooling and experience at each decile of the earnings distribution they find evidence that schooling and labor market experience had stronger earnings effects at higher deciles the native immigrant earnings gap varied by decile and in particular increased in the united states at higher deciles the results suggest that in the united states minimum wages compressed earnings at low deciles whereas in australia the minimum administered wage system compressed earnings across the entire distribution a pattern of higher earnings for immigrants than for the native born at the lowest earnings decile in australia may reflect favorable selectivity in migration

cracks in the glass ceiling gender and promotion in the economics profession gender differences in promotion within the economics profession have long been a concern of the committee on the status of women in the economics profession cswep in a descriptive analysis of the aea universal academic questionnaire rebecca blank 1996 finds that hires and promotions to the associateand fullprofessor levels have averaged 4 2 and 2 7 percentage points below the share of female assistants and associates professors respectively thus women appear to be underrepresented in senior positions suggesting they may face a glass ceiling this paper uses unique panel data for american economic association aea members to examine formally whether there are differences across gender in promotion probabilities an academic labor market beyond its direct interest to economists is well suited to study possible gender differences in promotion because departments can be ranked within the profession and because professors can be ranked within a department by a welldefined promotion hierarchy a focus on academic economists offers an additional advantage in that on the job productivity can be measured directly by research output other promotion studies have had limited controls for productivity and have used cross sectional data which do not permit controls for unobserved ability e g rudolf winter ebmer and josef zweimuller 1997 failure to account for gender differences in unobserved productivity could produce biased inference prior promotion studies also have generally relied on job advancement indexes that limit the distinction between initial job assignment i e an

male female wage differentials in job ladders much of the male female wage differential exists because men and women are assigned to different jobs within narrow job categories there is no male female differential only a tortured taste theory of discrimination can reconcile these facts we argue that differential movement along job ladders entails comparative advantage so the ability standard for promotion is higher for women this implies that more able women will be passed over in favor of less able men women assumed to have the same ability distribution as men earn less the differential reflects females lower promotion probability not within job discrimination

do residential water demand side management policies measure up an analysis of eight california water agencies abstract to assess the potential of price and alternative demand side management dsm policies as an urban water resource management tool an econometric model of residential demand is formulated and estimated this econometric model incorporates alternative dsm policy instruments such as water allocations use restrictions public education and increasing block pricing schedules the analysis relies on cross sectional monthly time series data for eight water agencies in california representing 24 of the state s population 7 1 million people results suggest that both price and alternative dsm policies were effective in reducing demand however the magnitude of the reduction in demand varied among policy instruments

separate and unequal occupation establishment sex segregation and the gender wage gap the authors report the first large scale empirical investigation of within job wage differences between men and women in the same occupation and establishment using data first on blue collar and clerical employees from 16 u s industries in 1974 83 and second on employees in 10 professional and administrative occupations the authors report three findings first wage differences at the occupation establishment level were small even without controls for individual level characteristics hence within job wage discrimination was much less important than occupation establishment segregation for observed wage differences second establishment segregation was an important cause although not as important as occupational segregation of wage differences third establishment segregation was extensive as was occupational segregation

school quality and black white relative earnings a direct assessment the wage differential between black and white men fell from 40 percent in 1960 to 25 percent in 1980 it has been argued that this convergence reflects improvements in the relative quality of black schools to test this hypothesis we assembled data on pupil teacher ratios annual teacher pay and term length for black and white schools in the eighteen segregated states from 1915 to 1966 these data are linked to estimated returns to education for southern born men from different cohorts and states in 1960 1970 and 1980 improvements in the relative quality of black schools explain 20 percent of the narrowing of the black white earnings gap between 1960 and 1980

gender discrimination without gender difference theory and policy responses abstract this paper provides an explanation for the continued existence of gender discrimination in competitive labour markets and analyzes the effects of policies designed to alleviate it unlike previous explanations of gender discrimination this theory arises from the interaction between women and men within the household and does not rely on inherent asymmetries between women and men even though discrimination is seen to be related to factors which can be thought external to the labour market such as higher job turnover and labour market exit rates for women policies which target only labour market outcomes and do not deal with external factors can both lead to reduced discrimination and also alter external factors thereby reducing discrimination further however policies aimed at external factors will in general be less effective in reducing discrimination unless combined with more direct policies

equal worth equal opportunities pay and promotion in an internal labour market using personnel data from a large financial company the authors find some evidence that women have to meet more stringent criteria than men for promotion but that much of the difference between men and women s attainment is due to their attributes for example lack of work experience is more important quantitatively than glass ceilings in preventing the preferment of women the authors data also suggest that the differential barriers confronting women are greatest at the lower end of the job ladder and that men and women may receive equal treatment once senior grades have been reached copyright 1996 by royal economic society

information provision and consumer behavior a natural experiment in billing frequency abstract in this study i estimate a causal effect of increased billing frequency on consumer behavior i exploit a natural experiment in which residential water customers switched exogenously from bimonthly to monthly billing customers increase consumption by 3 5 5 in response to more frequent information this result is reconciled in models of price and quantity uncertainty where increases in billing frequency reduce the distortion in consumer perceptions using treatment effects as sufficient statistics i calculate consumer welfare gains equivalent to 0 5 1 of annual water expenditures heterogeneous treatment effects suggest increases in outdoor water use

gender bias and credit access we extract an exogenous measure of gender bias from survey responses by descendants of u s immigrants on questions about the role of women in society we then use data on around 6 000 small business firms from 17 countries and find that in high gender bias countries female entrepreneurs are more likely to opt out of the loan application process and to resort to informal finance even though banks do not appear to actively discriminate against them these results are not driven by credit risk differences between female and male owned firms or by any idiosyncrasies in the set of countries in our sample

author s gender affects rating of academic articles evidence from an incentivized deception free laboratory experiment even though women s position in academia has changed dramatically over the last few decades there is still some evidence that when it comes to evaluation of scientific achievements gender may play a significant role gender bias is particularly likely to take the form of statistical discrimination in this study we sought to verify the hypothesis that researcher s gender affects evaluation of his or her work especially in a field where women only represent a minority towards this end we asked a sample of subjects mostly economics majors to evaluate a paper written by mixed gender couples indicating that it was co authored by a female economist male economist young female economist or young male economist or giving no information about the author at all while age factor played no role female authors appeared to be seen as less competent than males in that subjects being incentivized to give their best judgment less often believed that their papers have been published this effect did not interact strongly with the gender of the subject
