average cost pricing versus serial cost sharing an axiomatic comparison abstract a finite group of agents share a one output production function a cost sharing rule allocates the total cost among the users for every conceivable profile of output demands we investigate the space of possible cost sharing rules from an axiomatic perspective we provide two characterizations of average cost pricing one based on the axioms of additivity and monotonicity both with respect to the cost function and the other based on the axioms of additivity and a version of consistency we also provide a characterization of serial cost sharing based essentially on additivity and a free lunch axiom journal of economic literature classification numbers d63 d78 c79

valuing the attributes of renewable energy investments increasing the proportion of power derived from renewable energy sources is becoming an increasingly important part of many countries s strategies to achieve reductions in greenhouse gas emissions however renewable energy investments can often have external costs and benefits which need to be taken into account if socially optimal investments are to be made this paper attempts to estimate the magnitude of these external costs and benefits for the case of renewable technologies in scotland a country which has set particularly ambitious targets for expanding renewable energy the external effects we consider are those on landscape quality wildlife and air quality we also consider the welfare implications of different investment strategies for employment and electricity prices the methodology used to do this is the choice experiment technique renewable technologies considered include hydro on shore and off shore wind power and biomass welfare changes for different combinations of impacts associated with different investment strategies are estimated we also test for differences in preferences towards these impacts between urban and rural communities and between high and low income households

equitable nonlinear price regulation an alternative approach to serial cost sharing abstract this paper examines the serial cost share rule from a perspective of nonlinear pricing the expenditure function concept is introduced to facilitate the modelling of a wide variety of pricing mechanisms including those featuring head taxes block pricing or volume discounts axioms on equitable price regulation are shown to characterize the serial expenditure function a pricing mechanism which induces the distribution of serial cost shares several such characterizations are offered in a variety of technological contexts journal of economic literatureclassification numbers d63 c71

immigrant participation in the welfare system this paper presents a systematic analysis of immigrant participation in the us welfare system using the 1970 and 1980 us censuses in contrast to the previous studies the researchers focused on changes in welfare use across immigrant cohorts over time for a single immigrant cohort as it assimilates to the us furthermore it develops a theoretical model of the migration decision that explicitly incorporates the income insurance aspect of the us welfare system the analysis revealed that recent immigrant cohorts use the welfare system more intensively than earlier immigrant waves also the immigrant welfare participation was greater the longer an immigrant household had resided in the us and those characteristics of the immigrants country of origin were important determinants of welfare participation in addition the theoretical model of the migration decision which explicitly incorporated the presence of a welfare system in the destination country and this model could account for some of the ways in which source country characteristics were found to affect immigrant welfare participation

consumer preference for a no choice option the traditional focus in the decision making literature has been on understanding how consumers choose among a given set of alternatives the notion that preference uncertainty may lead to choice deferral when no single alternative has a decisive advantage is tested in seven studies building on recent research the article shows that the decision to defer choice is influenced by the absolute difference in attractiveness among the alternatives provided and is not consistent with trade off difficulty or the theory of search these findings are then extended to show that choice deferral can also be modified for the same alternatives by manipulations that make them appear more similar in attractiveness or that decrease the need to differentiate among them the results are consistent with the notion that preference uncertainty results in a hesitation to commit to any single action since small differences in attractiveness among the alternatives are potentially reversible consistent with this premise the effect of attractiveness difference on choice deferral decreased significantly when subjects were first allowed to practice making monetary trade offs among the available alternatives

three million foreigners three million unemployed immigration flows and the labour market in france this paper investigates the effect of the flows of immigrant workers on the french labour market from the mid 1970s to the mid 1990s using a system of equations for unemployment labour force participation the real wage and the immigration rate it is shown that in the long run both legal and amnestied immigrant workers and immigrant families lower the unemployment rate permanently in the short run the arrival of immigrants increases unemployment slightly with an impact effect similar to that of an increase in domestic labour force participation the composition of immigration flows matters and the results indicate that the distribution between workers from the european union and other regions of the world also more skilled and less skilled workers should remain balanced

effects of immigration on house prices in canada from the turn of the present century until late 2008 house prices in some developed countries including canada rose sharply compared to the increases in their per capita incomes some in the public circles of these countries argue that immigration fueled this rise each year canada admits about 225 000 immigrants but information on the effect of immigration on house prices in this country is lacking our extensive econometric analysis based on panel data at census division levels obtained from the 1996 2001 and 2006 population censuses indicates a statistically significant but small effect of immigration on prices of privately owned dwellings in canada an out migration of the native born from the areas where new immigrants settle or an increased supply of housing due to expectations of higher demand in those areas may have caused this result

immigration and the family this article studies the role of the family in determining the skill composition and labor market experiences of immigrants in the united states our theoretical framework based on the assumption that family migration decisions maximize household income shows that the family attenuates the selection characterizing the skills of the immigrant population the empirical analysis uses the 1970 and 1980 public use samples of the u s census and reveals that an immigrant s skills and labor market performance are greatly influenced by the composition of the household at the time of migration and by his placement in the immigration chain

the impact of the 1962 repatriates from algeria on the french labor market this paper uses census data to examine the impact on the french labor market of the 900 000 people repatriated from algeria in 1962 repatriates settled in regions culturally and climatically simil

migration theories and evidence an assessment abstract this paper presents a critical survey of theories of migration their welfare and policy implications and their empirical relevance we also develop some extensions to the theory beginning with the harris and todaro ht model in particular the ht model is extended to examine risk averse behaviour within families where the migration of members of families serves to diversify risk the welfare implications of the individual migration decision and government intervention in the form of employment subsidies are examined recent evidence on international migration is presented it is shown that migration does not flow automatically in response to wage differentials characteristics of migrants and the process of self selection are found to be important determinants of the rate of migration

balancing energy strategies in electricity portfolio management traditional management of electricity portfolios is focused on the day ahead market and futures of longer maturity within limits market participants can however also resort to the balancing energy market to close their positions in this paper we determine strategic positions in the balancing energy market and identify corresponding economic incentives in an analysis of the german balancing energy demand we find that those strategies allow an economically optimal starting point for real time balancing and create a marketplace for flexible capacity that is more open than alternative marketplaces the strategies we proffer in this paper we believe will contribute to an effective functioning of the electricity market

consumers willingness to pay for green electricity a meta analysis of the literature at present electricity generated from power plants using renewable sources costs more than electricity generated from power plants using conventional fuels consumers bear these expenses directly or indirectly through higher prices for renewable energy or taxes the number of studies published over the last few years focusing on people s preferences for renewables has increased steadily making it more and more difficult to identify key explanatory factors that determine people s willingness to pay wtp for renewables we present results of a meta regression on valuation of consumer preferences for a larger share of renewable energy in their electricity mix our meta regression results reveal a number of important factors that explain the differences in wtp values for renewable energy different valuation methods show widely different values with choice experiments producing the highest estimates our results further indicate that consumers wtp for green electricity differs by source with hydropower being the least valued variables that are often omitted from primary valuation studies are important in explaining differences in values these variables describe individual and household characteristics as well as information on the type of power plant that will be replaced by renewables further the marginal effect of a survey conducted in the us is pronounced we also assess the potential for using the results for out of sample value transfer and find a median error of 21 c 2015 elsevier b v all rights reserved

how to measure labour market effects of immigration a review abstract this paper surveys available empirical evidence on labour market effects of immigration many different approaches have been used already to try to find out whether immigration hurts the labour market opportunities of natives no doubt new approaches will follow in the future as globalization will keep the migration issue on the agenda this literature review discusses the different approaches concentrating on both the methodology and the results at the end it tries to summarize available evidence

erratum to environmental determinants of cost sharing multiple cost sharing rules often coexist in seemingly identical environments we use shared irrigation costs as a context for examining the extent to which the structural environment explains cost sharing rule selection we find that environmental factors affecting irrigation costs and benefits as well as those determining irrigator distribution along the ditch have impressive explanatory power these results present some of the first formal empirical analysis of the manner in which structural features influence the actual cost sharing choices of economic agents moreover our results also suggest that previous axiomatic studies are reflective of real world cost sharing behavior

regional labor markets and the determinants of wage inequality from 1972 to 1990 the united states experienced the largest increase in wage inequality of any developed country the spread in log wages between the 90th and 10th percentiles of the male wage distribution increased by about 60 points and inequality increased within virtually every demographic or skill category of the labor force see chinhui juhn et al 1993 various explanations have been offered including changes in the relative demand for skill intensive goods international trade immigration of less skilled workers and increased labor force participation of women yet attempts to quantify the relative importance of these factors have not met with much success this leaves skill biased technical change as the residual claimant that rationalizes the data this paper uses regional differences in the evolution of wage inequality to provide new evidence on the determinants of relative wages using a model of factor demand in geographic markets i isolate contributions of i changing skill ratios in the labor force ii increased participation of women iii technical change and iv changes in the industrial composition of labor demand the data indicate that changing skill ratios and women s labor supply have affected the wages of low skilled men in the west the data indicate that increased immigration of less skilled hispanic and asian workers has adversely affected the wages of natives causing a greater increase in inequality there than in any other region of the country i modeling wage inequality in regional markets

residential willingness to pay for deep decarbonization of electricity supply contingent valuation evidence from hong kong abstract motivated by the government s proposed target of reducing co2 emissions by 30 of the 2005 level in the year 2020 we estimate the residential willingness to pay wtp for deep decarbonization of hong kong s electricity supply which is heavily dependent on coal fired generation our contingent valuation survey conducted in 2016 of 1460 households yields dichotomous choice data based on the respondents answers to a series of closed ended questions such data are less susceptible to the strategic bias that often plagues self stated wtp data obtained by direct elicitation via open ended questions using binary choice models we find that average wtp is 48 51 relative to current bills if the decarbonization target is achieved via natural gas generation and renewable energy however estimated wtp declines to 32 42 when decarbonization entails additional nuclear imports from china as the projected bill increase caused by the target s implementation is 40 our wtp estimates support the government s fuel mix policy of using natural gas and renewable energy to displace hong kong s coal generation

undocumented immigration and unemployment of u s youth and minority workers econometric evidence we use census based data on the state distribution of the undocumented alien population in analyzing the relationship between that population and unemployment among youth and minority workers in the united states regression results from our two equation models do not support commonly expressed fears that undocumented immigration has caused any substantial increases in joblessness among these presumably vulnerable groups although small amounts of displacement are indicated a sizeable reverse effect is evident undocumented immigrants tend to concentrate in states where labor markets for these marginal groups are most favorable excerpt

the changing labor market position of canadian immigrants this paper uses pooled 1971 1981 and 1986 canadian census data to evaluate the extent to which 1 the earnings of canadian immigrants at the time of immigration fall short of the earnings of comparable canadian born individuals and 2 immigrants earnings grow more rapidly over time than those of the canadian born variations in the labour market assimilation of immigrants according to their gender and country of origin are also analysed the results suggest that recent immigrant cohorts have had more difficulty being assimilated into the canadian labour market than earlier ones an apparent consequence of recent changes in canadian immigration policy labour market discrimination against visible minorities and the prolonged recession of the early 1980s summary in fre excerpt

regression toward mediocrity in economic stature this paper provides estimates of the correlation in lifetime earnings between fathers and sons intergenerational data from the national longitudinal survey are used earlier studies conducted for the united states report elasticities of children s earnings with respect to parent s earnings of 0 2 or less suggesting extensive integenerational mobility these estimates however are biased downward by error contaminated measures of lifetime economic status estimates presented in this paper correct for the problem of measurement error and find the intergenerational correlation in income to be on the order of 0 4 this suggests considerably less intergenerational mobility than previously believed jel j62

immigration from poor to wealthy countries experience of the united states the u s experience with immigration from poor countries is examined using the results of two projects carried out by the national bureau of economic research questions considered include what determines the supply of immigrants how such immigrants fare in the u s job market and how this immigration affects the prospects of native born workers annotation

intergenerational income mobility in the united states social scientists and policy analysts have long expressed concern about the extent of intergenerational income mobility in the united states but remarkably little empirical evidence is available the few existing estimates of the intergenerational correlation in income have been biased downward by measurement error unrepresentative samples or both new estimates based on intergenerational data from the panel study of income dynamics imply that the intergenerational correlation in long run income is at least 0 4 indicating dramatically less mobility than suggested by earlier research copyright 1992 by american economic association

wind hydro or mixed renewable energy source preference for electricity products when the share of renewable energy increases abstract while the share of renewable energy especially wind power increases in the energy mix the risk of temporary energy shortage increases as well thus it is important to understand consumers preference for the renewable energy towards the continuous growing renewable energy society we use a discrete choice experiment to infer consumers preferences when the share of renewable energy increases the study results indicate that consumers are generally willing to pay extra for an increasing share of renewable energy but the renewable energy should come from a mixture of renewable energy sources we also found that consumers prefer to trade with their current supplier rather than another well known supplier this study contributes to the energy portfolio theories and the theory of energy diversification in a consumer perspective the managerial implications of this study are also discussed

ordinal cost sharing abstract we ask how the best known mechanisms for solving cost sharing problems with homogeneous cost functions the value proportional and serial mechanisms should be extended to arbitrary problems we propose the ordinality axiom which requires that cost shares should be invariant under essentially all increasing transformations of the measuring scales following thevalueapproach first we present an axiomatization of the shapley shubik rule based on ordinality next we define and axiomatize two extensions of theserialmechanism which contrary to the friedman moulin rule are ordinal finally we note that the aumann shapley extension of theproportionalmechanism is not ordinal we propose and defend an alternative proportional extension which does satisfy ordinality journal of economic literatureclassification numbers d63 c71

social acceptance of renewable energy innovation an introduction to the concept this paper introduces the special issue on social acceptance of renewable energy innovation it is a collection of best papers presented at an international research conference held in tramelan switzerland in february 2006 while there are ambitious government targets to increase the share of renewable energy in many countries it is increasingly recognized that social acceptance may be a constraining factor in achieving this target this is particularly apparent in the case of wind energy which has become a subject of contested debates in several countries largely due to its visual impact on landscapes this paper introduces three dimensions of social acceptance namely socio political community and market acceptance factors influencing socio political and community acceptance are increasingly recognized as being important for understanding the apparent contradictions between general public support for renewable energy innovation and the difficult realization of specific projects the third dimension market acceptance has received less attention so far and provides opportunities for further research particularly from management scholars

densification what does it mean for fuel poverty and energy justice an empirical analysis energy is increasingly at the forefront of the global political agenda while there is a longstanding literature relating to fuel poverty and increasingly energy justice there remains little evidence which explores its link with the urban form specifically the purpose of this study is to explore the relationship between the urban consolidation hypothesis and the cultivation of energy justice in australia this study uses data from the household income and labour dynamics in australia hilda survey years 2007 2014 a national probability sample and indefinite life panel the substantive findings of this study demonstrate that for low income and renting households greater urban density corresponds to a higher likelihood of experiencing fuel poverty further for households with a dwelling type described as an apartment two or three storeys there is a separate and quite generalisable indication that this type of dwelling is associated with a lower likelihood of experiencing fuel poverty this study connects the debate regarding urban consolidation and energy consumption to the fuel poverty and energy justice literature alongside this contribution this study also provides policymakers and planners with new evidence to inform remediation policies that are directed at supporting the fuel poor

us consumers willingness to pay for green electricity abstract we analyze us consumers demand for environmental attributes of deregulated residential electricity services using results from a survey designed to elicit consumers willingness to pay for such attributes and using results from a hedonic analysis of actual price premiums charged for green electricity in several deregulated markets survey results suggest that many population segments are willing to pay for decreased air emissions even if there is no alteration in fuel source furthermore several groups are willing to pay significantly more when emissions reductions stem from increased reliance upon renewable fuels the hedonic analysis suggests that several product features not considered in the survey help explain real price premiums including fuel mix from newly created renewable generation capacity green e certification brand name and state of offer while survey and hedonic results are not easily compared due to limitations of the survey both point to similar values for key environmental attributes though the survey results are likely to overstate actual willingness to pay in sum the results suggest that consumer driven purchases can in part support the future of renewable generation capacity in the united states though reliance upon other policy alternatives may be needed if energy prices spike

risk aversion and technology mix in an electricity market this article analyzes the eff ect of risk and risk aversion on the long term equilibrium technology mix in an electricity market it develops a model where fi rms can invest in baseload plants with a fi xed variable cost and peak plants with a random variable cost and demand for electricity varies over time but is perfectly predictable at equilibrium the electricity price is partly determined by the random variable cost and the returns from the two kinds of plants are negatively correlated when the variable cost of the peak technology is high the return of peak plants is low but the return to baseload plants is high risk averse fi rms reduce the capacity of the riskiest technology and develop the capacity of the other compared to risk neutral fi rms in the particular case where a risk neutral fi rm invests heavily in baseload technology and only sparely in peak capacity a risk averse fi rm would invest less in baseload increase peak capacity and increase total installed capacity

migration and labour markets in oecd countries a panel cointegration approach this article examines the interaction between immigration and the host labour market of 14 organization for economic co operation and development oecd countries using nonstationary panel data methodology we estimate a trivariate vector error correction model vecm and derive causality tests to simultaneously assess the long and short term macroeconomic impact of newcomers on wages and unemployment levels in the host country the results suggest that an increase of migrants is likely to increase wages in the destination countries in the short run but to increase them in the long run there is no evidence of adverse effects on unemployment due to immigration in short and long term except for anglo saxon countries in the short term our findings also show that immigration is conditioned by levels of unemployment and wages especially in anglo saxon countries

designing conjoint choice experiments using managers prior beliefs abstract the authors provide more efficient designs for conjoint choice experiments based on prior information elicited from managers about the parameters and their associated uncertainty the authors use a bayesian design procedure that assumes a prior distribution of likely parameter values and optimizes the design over that distribution the authors propose a way to elicit prior information from managers and show in monte carlo studies that the procedure provides more efficient designs than the current procedures the authors provide an empirical application in which they elicit prior information on the parameter values and the associated uncertainty from managers here the bayesian design provides 30 50 lower standard errors of the estimates and an expected predictive validity that is approximately 20 higher

fuel mix diversification incentives in liberalized electricity markets a mean variance portfolio theory approach monte carlo simulations of gas coal and nuclear plant investment returns are used as inputs of a mean variance portfolio optimization to identify optimal base load generation portfolios for large electricity generators in liberalized electricity markets we study the impact of fuel electricity and co2 price risks and their degree of correlation on optimal plant portfolios high degrees of correlation between gas and electricity prices as observed in most european markets reduce gas plant risks and make portfolios dominated by gas plant more attractive long term power purchase contracts and or a lower cost of capital can rebalance optimal portfolios towards more diversified portfolios with larger shares of nuclear and coal plants

the legacy of immigration labour market performance and education in the second generation previous research finds that the children of immigrants or the second generation earn at least as much as other native born but that there are persistent ethnic differences in the intergenerational transmission of education and wages we explain why these results are not incompatible and extend the empirical evidence in several directions using the canadian survey of labour and income dynamics first we estimate a model of wages earnings and hours worked using modern econometric techniques to corroborate earlier us results of complete integration by the second generation in the labour market we find that ethnic differences in labour market performance are significant but that these difference do not alter conclusions about the relative performance of the second generation second we find a source of superior labour market performance for the second generation in higher educational attainment which constitutes an important legacy of immigration that should not be ignored third we find that the de

international migration under asymmetric information international migration under asymmetric information usually differs from international migration under symmetric information and often quite dramatically so and in counterintuitive ways since in real life information is indeed asymmetric it is somewhat surprising that hitherto the study of international migration has by and large proceeded without explicit recognition of the effect of informational asymmetry in this paper we show that when at the lowest skill level migration is desirable i e if the discounted wage differential is positive for the lowest skill level the introduction of asymmetric information results in a reduction of the quality and quantity of international migration or has no effect at all when at the lowest skill level migration is not desirable the discounted differential is not positive at the lowest skill level the introduction of asymmetric information may either result in migration by all or none when under asymmetric information workers can at some cost to themselves report to foreign employers their individual skill thus dissociate themselves from the group effect then provided the cost is small either a u pattern of migration with respect to skill level emerges or migration is uniformly pursued by all though some do and some do not invest in signalling when the source consists of more than 1 poor country it is impossible to predict migration under asymmetric information from a given country without explicitly accounting for changes in the parameters of the other for example a favorable change encouraging less migration taking place in 1 country will through a distinct impact on the overall composition of migration reduce migration from the other country finally allowing employers to discover after a while the true productivity of individual migrant workers we obtain the somewhat surprising result that under a reasonable set of assumptions eventual discovery may increase the quantity and quality of migration and also increase the wage enjoyed by the low quality migrants eventual discovery serves to mitigate the impact of group averaging that deters migration by the high skill workers due to migration of some such workers the prediscovery wage of the low skill workers arises in our case sufficiently to outweigh the effect of the future wage decline due to discovery authors

assimilation changes in cohort quality and the earnings of immigrants this paper reexamines the empirical basis for two facts that seem to be found in most cross section studies of immigrant earnings 1 the earnings of immigrants grow rapidly as they assimilate into the united states and 2 this rapid growth leads to many immigrants overtaking the earnings of the natives within 10 15 years after immigration using the 1970 and 1980 u s censuses this paper studies the earnings growth experienced by specific immigrant cohorts during the period 1970 80 it is found that within cohort growth is significantly smaller than the growth predicted by cross section regressions for most immigrant groups this differential is consistent with the hypothesis that there has been a secular decline in the quality of immigrants admitted to the united states

the labor market skills of recent male immigrants evidence from the current population survey using data from special supplements to the current population survey cps the authors track the education and hourly earnings of recent male immigrants to the united states in terms of these measures of labor market skills the cps data suggest that immigrants who came in the late 1980s were more skilled than those who arrived earlier in the decade this pattern represents a break from the steady decline in immigrant skill levels observed in 1940 80 census data despite the encouraging trend over the 1980s however the average skills of recent immigrants remain low by historical standards

labor market discrimination against hispanic and black men h ispanic american men have lower average wage rates than white non hispanics in 1975 the average white non hispanic male wage earner in the united states earned 5 97 an hour mexican men earned 4 31 72 as much as white non hispanics puerto rican men earned 4 52 76 as much and cuban men earned 5 33 89 as much as white non hispanics by way of comparison black men s average wages in 1975 were 4 65 78 of the white male wage several possible reasons for the hispanics lower wages come to mind among them are age and education geographic location immigration language difficulties and discrimination for example as shown in table 1 mexicans and puerto ricans are younger on average than the white non hispanic population and earnings tend to rise with age hispanics have lower average levels of education than white non hispanics and wages are positively associated with education many mexican americans live in the southwest where prices are relatively low moreover hispanics are more likely to be recent immigrants and to lack fluency in english than white non hispanics and so to be at a disadvantage in the labor market in addition there is a widespread belief that hispanics suffer from employment discrimination and cannot obtain the wages that their human capital would command if they were non hispanic whites how much of the wage differentials described above are due to each of these factors and to other inter group differences in wage related characteristics in particular how much impact does labor market discrimination have on the average hispanic man s wage and how does this compare with discrimination against blacks this paper provides answers to these questions a few other efforts have been made to analyze the relative earnings of hispanic and white nonhispanic men using 1960 and 1970 census data fogel 1966 poston and alvirez 1973 poston alvirez and tienda 1976 long 1977 and gwartney and long 1978 we use more recent data from the 1976 survey of income and education this data set enables us to measure wage rates more accurately and to specify the wage function more completely than does the census unlike previous analysts in estimating the wage function we take account of possible selectivity bias due to the distinction between average wage offers and average observed wages thus we hope to obtain a more accurate and up to date measure of labor market discrimination against hispanic men section ii explains the method used to separate the minority white non hispanic wage differential into the portions due to differences in average characteristics and the portion due to differences in unobserved factors and discrimination taking into account the possibility of selectivity bias in the observed wage sample section iii describes the data used in the study and the specification of the wage equation the breakdown of the observed wage differentials into components due to differences in participation in the wage and salary sector local price levels average characteristics and discrimination are presented in section iv section v summarizes our findings and discusses their implications for efforts to improve the economic situation of hispanics in the united states

immigration and public finances in oecd countries abstract this paper shows that the macroeconomic and fiscal consequences of international migration are positive for oecd countries and suggests that international migration produces a demographic dividend by increasing the share of the workforce within the population the estimation of a structural vector autoregressive model on a panel of 19 oecd countries over the period 1980 2015 reveals that a migration shock increases gdp per capita through a positive effect on both the ratio of working age to total population and the employment rate international migration also improves the fiscal balance by reducing the per capita transfers paid by the government and per capita old age public spending to rationalize these findings an original theoretical framework is developed this framework highlights the roles of both the demographic structure and intergenerational public transfers and shows that migration is beneficial to host economies characterized by aging populations and large public sectors

immigrant earnings relative to what the importance of earnings function specification and comparison points immigrant relative earnings estimates are sensitive to the choice of comparison point and the specification of earnings non sample mean comparisons borjas 1985 understate relative earnings simple earnings specifications linear education quadratic experience overstate relative earnings for both poorly and well educated immigrants specifications which ignore omitted variables understate the relative earnings of poorly educated immigrants and overstate those of well educated ones although measures of assimilation and changes in immigrant quality are insensitive to earnings specification they indicate strong earnings growth for post 1964 immigrants an overall decrease in immigrant quality and an increase in mexican immigrant quality

the economics of immigration this literature review concerns the impact of immigration on the economy of the host country focusing on the experience of the united states the emphasis is on the period from the 1970s to the 1990s the author shows that research earlier in this period generally concluded that the economic effects of immigration were positive but that more recent research on later migrations have generally concluded that immigration may be having an adverse effect on the earnings of native unskilled workers and be placing an increased burden on welfare programs the importance of such economic analysis for the formulation of appropriate migration policies is stressed

diversification of oil import sources and energy security a key strategy or an elusive objective this paper explores the relationship between the diversification of sources of imported oil and energy security of oil importing countries it examines the importance of diversification policy for oil importers explains why oil importers implement oil diversification policy and contextualizes the oil import diversification strategy in the overall energy security policy of oil importers the paper analyzes the factors and the contexts that affect the level of importance assigned to oil import diversification policy in oil importing countries and the limitations that may affect the successful implication of oil import diversification policy the examples are drawn from the world s top three oil importers the united states japan and china the policymakers in these and other oil importing countries place much importance on energy security the diversification of oil import sources is used as one of the strategies to enhance energy security in oil importing countries this paper is important for policymakers in oil importing countries as it provides them with a qualitative conceptual framework with which to evaluate the need to diversify their countries sources of imported oil and with which to identify the likely limitations to the successful implementation of oil import diversification policy

immigration and wages evidence from the 1980s this paper presents new evidence on the effects of immigration based on changes in the distributions of wages in 24 major u s cities during the 1980s we concentrate on measuring the effects of immigration at the lower tail of the wage distribution in particular we ask whether recent declines in the real earnings of the least skilled workers in the u s economy are related to immigration our empirical analysis reveals large differences across cities in the relative growth rates of wages for low and high paid workers nevertheless these differences bear little or no relation to the size of immigrant inflows excerpt

immigrant worker assimilation is it a labor market phenomenon the work in this paper contributes to the debate on the economic assimilation of immigrant workers in the u s labor market a model of simultaneous occupational choice and earnings is estimated for foreign born hispanic men foreign born east asian men and for native white men to test the general hypotheses of assimilation an important distinction is made between those who migrated as adults and those who migrated as children the results suggest that the appearance of assimilation may be the outcome of pre labor market experiences of individuals who migrate as children along with changes in u s immigration law that have relaxed skill criteria for entering immigrants

whatever the customer wants the customer gets exploring the gap between consumer preferences and default electricity products in germany abstract in liberalized electricity markets residential customers can choose their preferred provider and select among a variety of different electricity products including green power options successful product design and marketing strategies for green electricity may provide electricity providers with a competitive advantage while at the same time contributing to energy policy objectives this requires however a thorough understanding of customer preferences we investigate the relative importance of different product attributes in creating customer value and find that price and electricity mix are the two most important attributes the german electricity customers we surveyed in 2009 expressed an implicit willingness to pay a premium of about 16 for electricity from renewable sources we conclude that consumers are willing to pay a significant price premium for an upgrade from the current default electricity mix in germany to a more environmentally friendly default electricity mix and discuss implications for marketing strategy and energy policy our findings are based on a dataset of 4968 experimental choices made by 414 german residential consumers collected in a stated preference survey

wind electricity in denmark a survey of policies their effectiveness and factors motivating their introduction this paper surveys the development of the policies supporting the introduction of wind electricity in denmark in the last 15 years with special attention to the new policy introduced after a 2 year long debate the aim of this paper is to explore the roles of financial support policy certainty and planning constraints in the diffusion of wind electricity in denmark and the reasons prompting the change of the system in the current decade it is discovered that political uncertainty has badly affected the effectiveness of the feed in law in the years immediately after its introduction with regard to the new system it is concluded that the change has been prompted by generous conditions under the feed in law and by the desire to facilitate the modernisation of old turbines it is also concluded that incentive based systems can be more effective than tradable quotas in promoting the modernisation of renewable plants this finding is relevant to the development of energy policy in countries such as germany and spain where the average age of wind turbines is much younger than those existing in denmark

pareto improving immigration in an economy with equilibrium unemployment economists from around the industrialized world demonstrate the strength of both theories about the rise of economic inequality that is it the mechanical consequence of changes in such economic fundamentals as technology and demographic parameters and that it is the contingent consequence country specific and time specific changes in institutions they find that though institutions always play a crucial role in shaping inequality and sometimes preventing it still it creeps in

water allocation by social choice rules the case of sequential rules abstract this paper considers the problem of allocating shares of irrigation water to different agricultural agents with single peaked preferences with respect to their own shares we define two different sequential allocation rules that respect the asymmetry between the agents and maintain the properties of pareto efficiency and strategy proofness and we design a specific algorithm to apply these rules the results of the empirical application of these rules for the case of an irrigated area located in the ebro basin spain show that the designed sequential rules are able to substantially improve the efficiency of the currently applied proportional rule in context of severe scarcity of water and or high administrative water prices

canadian immigration policy the effectiveness of the point system and other instruments this paper examines the effects of changes in canadian immigration policy on the occupational composition of immigration we focus on 1967 changes that created a regulatory system including the point system that still forms the framework of canadian immigration policy we find that the point system provides some control over occupational composition but that its effectiveness in fine tuning is limited by the large number of other characteristics it seeks to control we also find that entry class and source country composition of inflow have impacts that have swamped the effects of the point system in the last two decades summary in fre

low and high skill migration flows free mobility versus other determinants we investigate what economic factors drive international migration of workers to france and how their influence varies across different skill levels under restrictive policies and through time as free mobility is implemented we find that neither incentives nor policy parameters are similar across skill levels migration drivers such as a network of compatriots and relative incomes influence the movement of low skill workers high skill individuals however move only according to financial opportunities be they standard of living or returns to skill within a class we conclude that competition for high skill workers among organization for economic co operation and development oecd countries requires more than free mobility to successfully attract high skill migrants even for a developed country such as france

undocumented mexico u s migration and the returns to households in rural mexico this paper presents estimates of net income gains to a sample of households in rural mexico from sending migrants illegally to the united states correcting for sample selectivity bias and it examines the role of expected income gains in driving illegal mexico u s migration there is no evidence that people who migrate illegally to the united states are above average contributors to household income either as workers in mexico or as mexico u s migrants however other things being equal villagers who are in the best position to contribute to household income as workers in mexico are positively selected not to migrate to the united states

on the wage growth of immigrants israel 1990 2000 this paper develops a descriptive methodology for the analysis of wage growth of immigrants that is based on human capital theory the sources of the wage growth are 1 the rise of the return to imported human capital 2 the impact of accumulated experience in the host country and 3 the mobility up the occupational ladder in the host country the model implies a nonlinear wage function that includes interactions between imported skills and local wage growth using data on native israelis and immigrants from the former soviet union of israel we estimate wage equations jointly for the two groups we find that upon arrival immigrants receive non return for imported skills in the ten years following arrival wages of highly skilled immigrants grow at 8 percent a year rising prices of skills occupational transitions accumulated experience in israel and an economy wide rise in wages account for 3 4 1 1 1 5 and 1 5 percent each in the long run the return for schooling converges to 0 027 substantially below the 0 069 return for natives we do not reject the hypothesis that the return for experience converges to that of natives and that immigrants receive a higher return for their unmeasured skills we find that there is some downgrading in the occupational distribution of immigrants relative to that of natives moreover the average wages of immigrants approach but do not converge to the wages of comparable natives the main reason for this is the low return to their imported skills jel j24 j31 j60
