homeownership and economic performance of immigrants in germany this paper investigates the homeownership gap between native and immigrant households in germany paying particular attention to the assimilation process of immigrant households a double cohort model is derived which circumvents the identification problem for separating age period and cohort effects and accounts for differences in the effects the empirical findings suggest that immigrant households are less likely to own their primary residence than comparable native households moreover the duration of residence in germany does not affect the homeownership probability of immigrants indicating that an assimilation process in homeownership between native and immigrant households did not take place this result is largely consistent with the german immigration policy which has focused predominantly on short run economic needs and has neglected long run economic effects of immigration

household level determinants of adoption of improved natural resources management practices among smallholder farmers in western kenya abstract integrated natural resources management inrm of which integrated soil fertility management isfm is a component offers considerable promise for increasing food production in kenya it nonetheless remains unclear whether isfm inrm techniques lend themselves easily to adoption by smallholder farmers using panel data collected in western kenya in 1989 and 2002 this study finds that resource constraints limit many farmers adoption of isfm inrm techniques the size of the farm owned by a household the value of its livestock off farm income family labor supply and the educational attainment and gender of the household head all had a significant positive effect on the likelihood of adoption similar factors were found to be statistically significant in discouraging abandonment of the practices under study there thus seem to exist reinforcing feedback between investments in soil fertility management and household wealth as measured by asset endowments our findings raise important questions as to whether isfm and related techniques are really affordable to poorer smallholder farmers

assessing green energy economy stimulus packages evidence from the u s programs targeting renewable energy the paper provides a comprehensive empirical assessment of american stimulus policies aimed at renewable energy re technologies we use an indicator based methodology to assess progress with respect to energy environmental and socio economic issues resulting from re stimulus programs linked to the american recovery and reinvestment act and review and analyze the emerging but scattered literature overall our results indicate that stimulus programs have had a positive effect on the re sector this is despite the fact that they were originally planned to work in combination with a greenhouse gas cap and trade system which has not been implemented from the methodological perspective our approach is resource intensive and our analysis highlights numerous challenges notably related to causality and additionality despite these limitations this research improves our understanding of the broad effects and impacts of re stimulus programs

land tenure security and investment does strength of land right really matter in rural burkina faso abstract the causal relationship between land tenure security and agricultural investment plays a crucial role in the process of rural development land property rights are key determinants for reducing poverty through agricultural productivity natural resource management and socio economic inequalities growing competition for land access increases the sensitivity in land socio economic stakes and related policies in developing countries this paper analyzes the impacts of land rights on land related investment in rural burkina faso we use rural representative panel data and appropriate methods the two stage conditional maximum likelihood approach is used for dealing with endogeneity while the generalized structural equation model allows us to control for random effects we show that stronger land rights increase land attached investment and land investment has positive and negative effect on stronger and weaker land rights respectively in rural burkina faso our study also finds that women and immigrants have less land rights than men and natives respectively our contribution to related literature includes the use of rigorous process of hierarchy in land rights the close link of the results with land right strength is of great interest for cautious practitioners in land tenure and investment moreover our results imply that a gain of efficiency can be achieved from combining practices in land tenure and investment

portfolio choices of parents and their children as young adults asset accumulation by african american families the portfolio composition decision often is stylized as either a life cycle choice to allocate income to consumption or as a choice along a risk return locus with the locus derived from the underlying market equilibrium of asset returns and prices empirical work on household financial behavior has identified large differences in wealth levels and in portfoliocomposition choices of different demographic groups well beyond income and risk tolerance by far the most striking difference in this literature emerges when the population is subdivided by race for example given the strong performance of the u s equity market in the past decade portfolio choices of stocks have been key to wealth building yet africanamerican families have been less likely to have held stocks as of the mid 1980 s and less likely to have become shareholders over the period 1989 1994 erik hurst et al 1998 this paper attempts to resolve this puzzle by examining cross generational influences on current portfolio composition decisions

the role of the family in immigrants labor market activity an evaluation of alternative explanations comment most research on the labor market outcomes of immigrants has studied the behavior of individuals focusing primarily on the wage assimilation process or the excess returns to experience which immigrants obtain in their destination country s labor market e g barry r chiswick 1978 george j borjas 1985 recently however attention has been directed to analyzing immigrant labor market outcomes in a family context an approach which combines information about an individual s own labor market opportunities and the family context in which labor market decisions take place in a previously published paper in this review michael baker and dwayne benjamin 1997 evaluate alternative explanations for the observed labor supply patterns of canadian immigrants in the 1986 1991 period specifically when immigrant husbands arrive in canada they typically work less than comparable natives however immigrant wives work more than natives other things equal with assimilation the labor supply of immigrant husbands eventually catches up to that of natives while immigrant wives labor supply falls relative to comparable natives and is ultimately overtaken by that of natives the authors take these patterns to be most consistent with a family investment model in this scenario upon arrival husbands invest in their human capital while wives work to provide the family with liquidity during this investment period with increased time in canada husbands labor supply increases rapidly due to their growing skills in the canadian labor market while wives labor supply falls off in part because they originally took dead end jobs upon arrival in order to finance their husbands investments in human capital interestingly while most of the findings reported by baker and benjamin are consistent with the family investment model their estimated wage equations are not although they do not comment on this in discussing the appropriateness of the family investment model specifically they find similar rates of wage assimilation for husbands and wives this finding suggests roughly equal propensities to invest in one s own human capital for both groups this is contrary to the family investment hypothesis and does not match their story of dead end jobs for wives and large human capital investments of their husbands an alternative possible explanation for the patterns observed by baker and benjamin involves a simple price model in which the observed labor supply patterns reflect laborsupply responses to each spouse s wages for example the initially high but eventually falling level of wives labor supply relative to comparable natives could be a response to their husbands initially low but rising wages while this reasoning like the family investment model is broadly consistent with the data the authors conclude that the simple price model cannot be the entire explanation since in order to explain the full labor supply patterns of immigrants it would require unrealistically high labor supply elasticities and further that the assimilation patterns noted above remain even when wages of husband and wife are controlled blau school of industrial and labor relations cornell university 265 ives hall ithaca ny 14853 and nber and cesifo kahn school of industrial and labor relations cornell university 264 ives hall ithaca ny 14853 and cesifo moriarty school of industrial and labor relations cornell university ilr graduate student mailboxes ives hall ithaca ny 14853 souza faculdade de economia administracao e contabilidade university of sao paulo avenida professor luciano gualberto 908 cidade universitaria predio fea 1 sao paulo sp 05508 brazil the authors thank three anonymous referees for helpful comments and suggestions portions of this paper were written while blau and kahn were visiting scholars at the russell sage foundation to which they are grateful for research support

the unemployment experience of male immigrants in england in this paper the unemployment experience of immigrant men in the english labour market is examined using 1993 1994 data from the quarterly labour force survey of the united kingdom hypotheses proposed by chiswick 1982 are investigated for both the claimant count and the ilo measures of unemployment using logistic regression analysis our results show that recent white and nonwhite immigrant men experience much higher levels of unemployment than earlier cohorts for whites this effect is transitory whereas for nonwhites unemployment rates adjust more slowly as the duration of stay increases immigrant unemployment rates also vary considerably with country of birth

certification and access to export markets adoption and return on investment of organic certified pineapple farming in ghana summary global food markets demand adherence to food standards by farmers in developing countries such as globalgap and organic certifications this paper analyzes the adoption and profitability of certified farming using farm level data of 386 ghanaian small scale pineapple farmers we employ an endogenous switching regression model to examine the adoption and impact of organic certification on the return on investment roi in pineapple farming the empirical results indicate that both organic and globalgap certification achieve a positive roi however organic certified farming yields a significantly higher roi than globalgap certified farmers mainly due to the price premium on the organic market

do overlapping property rights reduce agricultural investment evidence from uganda the need for land related investment to ensure sustainable land management and increase productivity of land use is widely recognized however there is little rigorous evidence on the effects of property rights for increasing agricultural productivity and contributing toward poverty reduction in africa whether and by how much overlapping property rights reduce investment incentives and the scope for policies to counter such disincentives are thus important policy issues using information on parcels under ownership and usufruct by the same household from a nationally representative survey in uganda the authors find significant disincentives associated with overlapping property rights on short and long term investments the paper combines this result with information on crop productivity to obtain a rough estimate of the magnitudes involved the authors make suggestions on ways to eliminate such inefficiencies

the earnings of male immigrants in england evidence from the quarterly lfs in this paper we estimate earnings functions for native born and foreign born white and non white males in the english labour market using data from the quarterly labour force survey our results highlight the importance of distinguishing between native born and foreign born males when investigating the labour market experience of ethnic minorities furthermore the earnings performance amongst white immigrants varies considerably

intertemporal market effect on gender earnings differentials lawyers in canada 1970 80 the conventional methodology for decomposition of cross sectional earnings differentials is extended to include a market effect on intertemporal changes in earnings and to analyse the changes in gender differentials over time the integrated cross sectional and intertemporal methodology is illustrated by a decomposition of the change in the earnings differential that occurred during the 1970s between male and female lawyers in canada an unprecedented rate of growth in the supply of lawyers during the 1970s in canada was associated with changes in the gender earnings differential in the legal profession this rapid supply growth had an almost negligible net impact on female earnings but a negative impact of 15 on the male earnings this explains the narrowing of the earnings differential by almost 30 over the decade although three fifths of the gender differential in 1970 and half of the differential in 1980 were attributable to the differences in the characteristics of the two groups these chang

a comparative analysis of the nativity wealth gap this paper investigates the source of the gap in the relative wealth posi tion of immigrant households residing in australia germany and the united states our results indicate that in germany and the united states wealth difierentials are largely the result of disparity in the educational attainment and demographic composition of the native and immigrant populations while income difierentials are relatively unimportant in understanding the nativity wealth gap in contrast the relatively small wealth gap between australian and foreign born households exists because immigrants to australia do not translate their relative educational and demographic advantage into a wealth advantage on balance our results point to substantial cross national disparity in the economic well being of immigrant and native families which is largely consistent with domestic labor markets and the selection policies used to shape the nature of the immigration ow

entry to home ownership in germany some comparisons with the united states new research on migration mobility and housing tenure choice using the concept of the life course is providing an enriched analysis of the context within which housing choices are made and of the demographic and economic variables which are critical determinants of the decisions to move and to change tenures the availability of panel series data for the us and germany allows cross national comparisons of the migration and tenure choice processes there are substantial differences in the rates of mobility and the rates of moves of households from the rental sector to ownership especially for couples but the results confirm the overall similarities in the mobility and tenure choice processes despite the differing government commitments to housing policy the models show that it is primarily couples and families who make the transition to ownership and that income and number of earners are important in both contexts and german households have even higher incomes before they make the transition to ownersh

tenure security human capital and soil conservation in an overlapping generation rural economy we develop an overlapping generation model of rural agricultural households to examine whether tenure security and subsistence needs influence the choice between unexploited topsoil and investment in children s human capital as the mode of transfer of wealth a unique dataset from bangladesh finds that tenure security is associated with greater topsoil conservation and lower human capital investment therefore there exists a tradeoff between these two modes of transfer we suggest that increased public expenditure on schooling which substitutes private expenditure may lower the pressure on land and soil resources

social security eligibility and the labor supply of older immigrants the employment rate of native born men falls at a much faster rate than that of immigrants as the two groups approach the age of retirement the author draws on u s census data from 1960 2000 to examine how the eligibility requirements for social security benefits affect immigrants decisions to leave the labor market as they near retirement age because a person needs to have worked in the united states for at least ten years to qualify for benefits newly arrived immigrants may not yet have accumulated the requisite employment credits to do this and thus have greater employment rates than other comparably aged persons the probability that an older immigrant is employed falls once the ten year work rule is satisfied the implication of this finding is that immigration may affect the increase in retirement benefits that will inevitably occur as the baby boom generation retires

immigrants minorities and labor market competition this paper investigates the extent of labor market competition among immigrants minorities and the native population an analysis of 1980 u s census data reveals that immigrants tend to be substitutes for some labor market groups and complements for others the effects of shifts in immigrant supply on the earnings of native born men are however very small on the other hand increases in the supply of immigrants do have a sizable impact on the earnings of immigrants themselves an increase of 10 percent in the supply of immigrants for example reduces the immigrant wage by about 10 percent

agricultural expansion and deforestation modelling the impact of population market forces and property rights abstract this paper compares four different modelling approaches to agricultural expansion and deforestation and explores the implications of assumptions about the household objectives the labour market and the property rights regime a major distinction is made between population and market based explanations many of the popular policy prescriptions are based on the population approach assuming subsistence behaviour and limited market integration within a more realistic particularly for the long term effects market approach well intentioned policies such as agricultural intensification programmes may boost deforestation many forest frontier contexts are also characterized by forest clearing giving farmers land rights deforestation becomes an investment to the farmer and a title establishment strategy land titling and credit programmes may therefore increase deforestation

recent trends in the size distribution of household wealth based on the survey of consumer finances the distribution of wealth in the united states became much more unequal in the 1980s and that trend continued albeit at a slower pace in the 1990s the only households that saw their mean net worth rise in absolute terms between 1983 and 1995 were those in the top 20 percent and the gains were particularly strong for the top one percent all other groups were particularly strong for the top one percent all other groups suffered real wealth losses including the median household and declines were particularly precipitous at the bottom racial disparities widened and young households also lost out over this period

the profits of power land rights and agricultural investment in ghana we examine the impact of ambiguous and contested land rights on investment and productivity in agriculture in akwapim ghana we show that individuals who hold powerful positions in a local political hierarchy have more secure tenure rights and that as a consequence they invest more in land fertility and have substantially higher output the intensity of investments on different plots cultivated by a given individual corresponds to that individual s security of tenure over those specific plots and in turn to the individual s position in the political hierarchy relevant to those specific plots

selection on observed and unobserved variables assessing the effectiveness of catholic schools in this paper we measure the effect of catholic high school attendance on educational attainment and test scores because we do not have a good instrumental variable for catholic school attendance we develop new estimation methods based on the idea that the amount of selection on the observed explanatory variables in a model provides a guide to the amount of selection on the unobservables we also propose an informal way to assess selectivity bias based on measuring the ratio of selection on unobservables to selection on observables that would be required if one is to attribute the entire effect of catholic school attendance to selection bias we use our methods to estimate the effect of attending a catholic high school on a variety of outcomes our main conclusion is that catholic high schools substantially increase the probability of graduating from high school and more tentatively attending college we find little evidence of an effect on test scores

the economic situation of first and second generation immigrants in france germany and the united kingdom a central concern about immigration is the integration into the labour market not only of the first generation but also of subsequent generations little comparative work exists for europe s largest economies france germany and the uk have all become perhaps unwittingly countries with large immigrant populations albeit with very different ethnic compositions today the descendants of these immigrants live and work in their parents destination countries this article presents and discusses comparative evidence on the performance of first and second generation immigrants in these countries in terms of education earnings and employment it is widely believed that many european countries have a serious problem with the integration of immigrants and their children leed 2006 many northern european countries have accumulated sizeable populations of immigrants but the lack of longterm strategies and policies to integrate these into societal structures and the labour market is often cited as one reason for social and economic exclusion of the children of these immigrants in the past decade southern european countries such as spain and italy have experienced similar if not larger immigrations than the large northern european economies france germany and the uk in the late 1950s to early 1970s again it seems that there is little thought devoted to long term strategies for immigrants and their descendants the experience of those countries that had large scale immigration in the last half of the twentieth century should be of importance for devising future immigration and integration policies however there is rather little hard evidence in the literature about the relative position of immigrants and their descendants in these countries in a manner that allows comparisons to be made in this article we aim to provide a comparative study of a number of outcomes education earnings and employment of both first and second generation immigrants of different origins in the three largest european economies france germany and the uk

credit constraints and the labour supply of immigrant families in canada the hours of work decisions in immigrant and nonimmigrant families are compared using an intertemporal labor supply model estimated over data from the 1981 and 1991 census of canada surveys the family investment hypothesis is evaluated the hypothesis states that the immigrant family is unable to borrow in the first years after migration and that the immigrant wife responds by working longer hours so as to support family consumption and her husband s labor market adjustment the empirical evidence in general supports the hypothesis since credit constraints are found to significantly distort the labor supply decisions of recently arrived immigrant families

entry growth and survival in the green industry abstractentry growth and survival in the green industry regional studies economists are interested in the factors that induce firm entry lead to growth and help firms succeed in various markets such information can be helpful to policy makers but unfortunately such patterns have not been considered for green industries this paper takes advantage of a recent definition of green industries proposed by the us bureau of labor statistics bls to investigate patterns characterizing these industries within the state of texas

land tenure and property rights theory and implications for development policy this article explores the nature of property rights systems their evolution and their effect on resource allocation it is argued that certain institutional arrangements for land rights have evolved in order to reduce uncertainty and increase efficiency in credit as well as in land markets of particular relevance to developing countries the article emphasizes the contribution of public sector infrastructure to effective land rights systems an appendix to the article presents a formal model analyzing the effects of security of land rights on land prices the intensity of cultivation and the use of credit empirical evidence from thailand supports several of the propositions derived from the model

land tenure systems and their impacts on agricultural investments and productivity in uganda this article provides an empirical analysis of the impact of different tenure systems mailo customary and public land on agricultural investment and productivity in central uganda a major hypothesis tested is that land investments and practices may have both economic and tenure security implications the results indicate that coffee planting is used by farmers to enhance tenure security while fallowing is practised to a greater extent by farmers on more secure holdings this supports the notion that farmers consider tenure implications when making investments and that different tenure systems do not inhibit the promotion of tree planting investment tenure had no impact on the productivity of crop farming

the expansion of renewable energies and employment effects in germany the promotion of electricity produced from renewable energy is a high priority of the european union as well of its member states the german government wants to increase the share of renewable energies from about 5 to 12 by 2010 to attain this goal the german government has introduced compulsory compensation schemes for electricity produced from renewable energy fed into the public grid this paper examines the economic impact of this policy employing an econometric model particular emphasis was given to employment effects in general we distinguish two effects 1 an expansive effect resulting from additional investments and 2 a contractive effect resulting from an increase in the production cost of power the first effect will dominate during the first years and lead to an increase in employment of approximately 33 000 new jobs however the contractive effect will offset these gains and lead to a slightly negative employment balance by 2010

land tenure climate and risk management abstract we analyze to what extent climate conditions affect the prevalence of sharecropping as a form of traditional land tenure we investigate how sharecropping tenure is related to climate risk and how it interacts with fertilizer use and livestock ownership that both influence production risk we first develop a stylized theoretical model to illustrate the role of climate for land tenure and production our empirical analysis is based on more than 9000 households with considerable heterogeneity in climate conditions across several african countries we find that farmers in areas with low precipitation are more likely to be sharecroppers we further find evidence for risk management interaction effects as sharecropping farmers are less likely to own livestock and more likely to use fertilizer in economies where formal kinds of insurance are unavailable sharecropping thus functions as a form of insurance and reduces the need for potentially costly risk management strategies

taxation of economic rents economic rents have long been identified as an efficient tax base in addition the recent literature documents that rent income is highly concentrated and that rents are quickly increasing rent taxation thus seems attractive for reasons of both efficiency and equity nevertheless rent taxation remains a marginal topic in research and policy making in a systematic review of the neoclassical literature on different rent types we find that some types of rents reflect inefficiencies and should thus be minimized while others reward investments and should be supported in line with social welfare what remains for taxation are land rents one of the few true scarcity rents land rents have significant potential to improve the efficiency of the tax system we then begin to develop a comprehensive theory of land rent taxation by identifying relevant efficiency and equity effects the interaction of many of these effects remains unexplored which might explain policymakers hesitation in using land taxes to date

crossing the border self selection earnings and individual migration decisions many empirical studies on the determinants of international migration flows rely exclusively on macro data and do not account for migrants self selection we analyze a very interesting episode in international migration for which we are able to gather individual level data covering all relevant countries namely the exodus of ecuadorians to spain and the us in the aftermath of the economic collapse of 1999 specifically we produce selection corrected predictions of counterfactual individual earnings and use them to estimate a discrete choice migration equation that allows for correlated errors across destinations and a rich structure of migration costs we find that earnings significantly shape individual migration decisions even in an episode in which ecuadorians mostly chose spain where earnings were lower than in the us and they contribute to explaining the observed composition of migration flows moreover our estimates show that changes in earnings at a particular destination have a larger effect on destination choice conditional on migration than on the scale of migration

examining the spatial patterns of green industries and the role of government policies in south korea application of a panel regression model 2006 2012 abstract driven by global competition for economic growth green industries and green jobs have become an important economic engine for sustainable and environmentally friendly development most of the existing literature on green industries has focused on defining the green industry and its economic impacts however little empirical research has been conducted on the spatial patterns of green industries such as their locational preferences we examined the spatial patterns of green industries in south korea over time and across municipal level administrative units si gun gu using the survey of business activities 2006 2012 which includes longitudinal establishment level employment data collected by the korea national statistical office we employed a panel data regression model to analyze green industries and their locational decisions the spatial analysis showed that green industries tend to locate in areas where conventional manufacturing industries were previously concentrated we also identified a new emerging geographic cluster of green industries the panel regression models indicated that some green industries such as the advanced green city industry sector tend to locate either within or near big cities in contrast the renewable energy industry sector tends to locate far from major cities in addition we confirmed that the 2009 framework act on low carbon and green growth law enacted by the korean government had a significant impact on the growth of the green industry however the act s impact ceased after 2010 indicating the importance of both subsequent policy initiatives and the creation of a private market for green industries and green jobs

homeownership in the 1980s and 1990s aggregate trends and racial gaps abstract housing policy under the clinton and bush administrations has sought to boost homeownership while also narrowing racial gaps in owner occupancy rates against that backdrop homeownership rose sharply in the 1990s but white minority gaps remain in excess of 25 percentage points we analyze these patterns using data from the 1983 to 2001 survey of consumer finances results indicate that household characteristics explain most of the increase in homeownership and roughly two thirds of the white minority homeownership gap credit barriers account for no more than 5 percentage points of the remaining gap this suggests that policy makers will need to look beyond innovations in mortgage finance if their goal is to further expand homeownership

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

optimal taxation timber and externalities abstract the paper presents a model of the relationship between timber taxation and externalities optimal pigouvian taxation formulas are derived within this framework for common taxes a simulation model of douglas fir is used to estimate the size and direction of these effects the results show that taxation policy can have a marked impact on the production of externalities depending on tree species and land productivity

green jobs economic impacts of renewable energy in germany abstract the labor market implications of large investment into renewable energy re are analyzed in this text although a growing re industry can be observed in germany the overall effect of large increases of re based electricity and heat generating technologies on the german economy require a careful model based analysis the applied model panta rhei has been used among others to evaluate the german energy concept in 2010 it takes positive and negative impacts of re into account the paper shows the overall effects under different assumptions for fossil fuel prices domestic installations and international trade the results are sensitive to assumptions on the development of re world markets and german exports to these markets almost all of these scenarios exhibit positive net employment effects under medium assumptions net employment of re expansion will reach around 150 thousand in 2030 only with assumptions for german re exports below today s level net impacts are slightly negative gross employment will increase from 340 thousand in 2009 to between 500 and 600 thousand in 2030

land tenure security and investment incentives puzzling evidence from burkina faso abstract the commonsense logic associating higher land security and higher incentives to invest has been recently called into question in the case of african agriculture to be meaningful empirical tests have to be carefully designed so as to take account of the possible endogeneity of the land rights variable this is done in this paper by applying suitable econometric methods to the original data collected in burkina faso the results obtained cast doubt on the existence of a systematic influence of land tenure security on investment by reviewing the justifications for scepticism in the recent literature we are able to conclude that the traditional village order where it exists provides the basic land rights required to stimulate small scale investment

does selling state silver generate private gold neighbourhood impacts of state house sales this paper utilises two politically determined natural experiments affecting state provided social housing to examine the impact that housing tenure status has on neighbourhood outcomes from 1990 new zealand s national government sold a substantial number of state houses either to existing tenants home buys or to other purchasers vacant sales from 1999 the labour government ended home buys reduced vacant sales and increased acquisitions while vacant sales had no material effects on local outcomes a higher prevalence of home buys led to increased local house price appreciation despite demographic trends that would otherwise have led to falling relative house prices in those communities

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

state renewable energy electricity policies an empirical evaluation of effectiveness over the past decade state governments have emerged as us energy policy leaders across the country states are adopting policy instruments aimed at carbon mitigation and renewable energy deployment one of the most prevalent and innovative policy instruments is a renewable portfolio standard rps which seeks to increase the share of renewable energy electrification in the electricity market this analysis evaluates the effectiveness of state energy programs with an empirical investigation of the linkage between state rps policy implementation and the percentage of renewable energy electricity generation across states we use a variant of a standard fixed effects model referred to as a fixed effects vector decomposition with state level data from 1998 to 2006 results indicate that rps implementation is not a significant predictor of the percentage of renewable energy generation out of the total generation mix yet for each additional year that a state has an rps policy they are found to increase the total amount of renewable energy generation these findings reveal a potentially significant shortcoming of rps policies political institutions natural resource endowments deregulation gross state product per capita electricity use per person electricity price and the presence of regional rps policies are also found to be significantly related to renewable energy deployment

land tenure differences and investment in land improvement measures theoretical and empirical analyses this article develops a theoretical framework to examine the relationship between land tenure arrangements and households investment in soil improving and conservation measures it then analyzes this relationship with a multivariate probit model based on detailed plot level data from villages in the brong ahafo region of ghana a major hypothesis tested is that investment in productivity enhancing and conservation techniques are influenced by land tenure arrangements the theoretical analysis and empirical results generally reveal that land tenure differences significantly influence farmers decisions to invest in land improving and conservation measures the findings also show that tenure security does affect farm productivity

the effect of minimum wages on immigrants employment and earnings this study examines how minimum wage laws affect the employment and earnings of low skilled immigrants and natives in the u s minimum wage increases might have larger effects among low skilled immigrants than among natives because on average immigrants earn less than natives due to lower levels of education limited english skills and less social capital results based on data from the current population survey for the years 1994 2005 do not indicate that minimum wages have adverse employment effects among adult immigrants or natives who did not complete high school however low skilled immigrants may have been discouraged from settling in states that set wage floors substantially above the federal minimum jel classifications j23 j38 j15

estimation in a class of simultaneous equation limited dependent variable models estimation in a class of simultaneous equation limited dependent variable models is considered the minimum chi squared method is used to compare the asymptotic relative efficiency of marginal and new conditional maximum likelihood estimators for this class of models efficient minimum chi squared estimation procedures are described a two step algorithm based on a conditional maximum likelihood estimator provides a natural framework for both computing a linearized and locating the joint maximum likelihood estimator the unimodality of the simultaneous equation tobit likelihood function is proved and this model is used to illustrate the empirical application of some of the estimators considered in the paper the relative efficiency of these estimators in the simultaneous equation tobit model is examined in a set of monte carlo experiments many applications of microeconomic theory to individual data face the joint problems of censoring and simultaneity in particular the dependent variable under investigation may not be continuously observed and some of the conditioning variables representing the outcome of other decisions by the individual may be simultaneously determined smith and blundell 1986 developed an asymptotically efficient test for exogeneity or simultaneity in the simultaneous equation tobit model as a byproduct a conditional maximum likelihood estimator was obtained which is consistent under the alternative hypothesis of simultaneity nelson and olsen 1978 amemiya 1978 1979 and heckman 1978 consider a number of consistent marginal maximum likelihood estimators based on marginal maximum likelihood estimators of the reduced form parameters for the probit and tobit models in contrast the estimator derived from smith and blundell 1986 is based on the corresponding conditional maximum likelihood estimators this paper is concerned with estimation in a class of simultaneous limited dependent variable regression models which includes the simultaneous probit and tobit models as special cases analogous marginal and conditional maximum likelihood estimators to those of nelson and olsen 1978 amemiya 1978 1979 heckman 1978 and smith and blundell 1986 are derived and other new estimators are suggested the minimum chi squared approach discussed by ferguson 1958 malinvaud 1970 and rothenberg 1973 is used to compare the asymptotic relative efficiency of various estimators considered a simple two step algorithm based on the conditional maximum likelihood

new evidence on the economic progress of foreign born men in the 1970s and 1980s this study examines the economic progress of foreign born men in the united states europeans entered the united states with relatively high wages and earned wages comparable to natives over their life course japanese korean and chinese men entered with lower wages but quickly caught up with u s born workers mexicans and central americans entered with low wages and the wage gap between themselves and u s born workers has not shrunk disparities in completed years of education and whether education was received in the united states can explain a large share of the differences in the level of wages for immigrants from some countries it is found that more highly educated men assimilate more quickly the rate of economic progress has not improved for more recent arrivals from any country but this is most problematic among mexicans and central americans because of their relatively low rates of wage growth excerpt

black white differences in wealth and asset composition using data from the 1976 and 1978 national longitudinal surveys of young men and young women this study examines racial differences in the magnitude and composition of wealth and the reasons for them on average young black families hold 18 percent of the wealth of young white families and hold their wealth in proportionately different forms even after controlling for racial differences in income and other demographic factors as much as three quarters of the wealth gap remains unexplained we speculate on the causes for this concluding that racial differences in intergenerational transfers and to a lesser extent barriers to the accumulation of business and home equity most likely play a role

forest resource depletion soil dynamics and agricultural productivity in the tropics abstract a two sector dynamic model for agriculture and forestry is proposed agricultural yields are a function of the rate of deforestation the forest stock and purchased inputs we examine the impact of changes in the social discount rate net returns to agriculture and direct marginal benefits of the forest stock benefits on the optimal deforestation path under the assumption of a quadratic agricultural yield function finally steady state comparative static analysis is conducted

spatial housing economics a survey this introduction to the virtual special issue surveys the development of spatial housing economics from its roots in neoclassical theory through more recent developments in social interactions modelling and touching on the role of institutions path dependence and economic history the survey also points to some of the more promising future directions for the subject that are beginning to appear in the literature the survey covers elements of hedonic models spatial econometrics neighbourhood models housing market areas housing supply models of segregation migration housing tenure subnational house price modelling including the so called ripple effect and agent based models possible future directions are set in the context of a selection of recent papers that have appeared in urban studies nevertheless there are still important gaps in the literature that merit further attention arising at least partly from emerging policy problems these include more research on housing and biodiversity

behavioural and material determinants of production relations in agriculture in this essay we develop a framework for analysing the major institutions governing the production and exchange of output and the primary factors of production in rural areas the analysis incorporates general considerations of risk and information constraints jointly with the principal material attributes of agriculture and of agricultural production factors the framework is used to analyse barriers to the existence of the major intertemporal and factor markets it is applied specifically to land scarce environments for which it provides an internally consistent explanation for many of the well documented institutional features of such settings in addition the analysis provides new implications for among other phenomena the inter relationships among ownership holdings operational scale family size and factor productivity for the scarcity of animal rental markets and use of animals as collateral for the renting out of land by small landowners and for the existence of plantations for certain crops

why are hispanic and asian american homeownership rates so low immigration and other factors abstract the homeownership rates of hispanic and asian american households are significantly less than that of other demographic groups in the us especially after accounting for income and other characteristics this naturally leads to an investigation of the impact of immigration characteristics of various groups on the propensity for homeownership it is found that being an immigrant has a substantial negative effect on the probability of being a homeowner but that this effect dissipates over time the relative youth of these two groups in and of itself plays a significant role in lowering their homeownership rate as does the relatively high rate of residence in areas with high value rent ratios

empowerment and efficiency tenancy reform in west bengal the paper analyzes the effect of agricultural tenancy laws offering security of tenure to tenants and regulating the share of output that is paid as rent on farm productivity theoretically the net impact of tenancy reform is shown to be a combination of two effects a bargaining power effect and a security of tenure effect analysis of evidence on how contracts and productivity changed after a tenancy reform program was implemented in the indian state of west bengal in the late 1970s suggests that tenancy reform had a positive effect on agricultural productivity there

clean energy policies and green jobs an evaluation of green jobs in u s metropolitan areas state and local governments in the u s are actively promoting renewable energy and energy efficiency to seek economic development opportunities and create green jobs this study evaluates the employment effects of state and local clean energy and climate policies in u s metropolitan areas msas in 2006 the regression analysis shows that both state and local clean energy policies have positive and statistically significant impacts on green jobs at the metropolitan level the results from two stage probit least squares 2spls indicate that every additional state clean energy policy tool adopted is associated with 1 more green jobs in the msa on average msas with iclei membership maintain 9 3 more green jobs than msas without iclei membership ceteris paribus

homeownership social capital and satisfaction with local government prior studies suggest that homeownership positively impacts on social capital formation however many studies find it difficult to control adequately for selection effects in the form of factors some of which may be unobserved that encourage both homeownership and investment in social capital by households a biennial survey conducted in new zealand cities provides data that enable the control of such selection effects with propensity score matching methods while also benchmarking the results by means of regression methods the results confirm that homeownership exerts positive impacts on the formation of social capital at the same time homeownership demands greater accountability of local government and leads to reduced satisfaction with local government performance thereby negatively impacting on community social capital hence these two dimensions of housing related social capital work in opposite directions from each other a finding which has not been previously observed

farmland rental prices in gm soybean areas of argentina do contractual arrangements matter abstractin this paper we study the determinants of the rental price of farmland in the argentinian pampas in particular we examine the price of lease contracts using a hedonic price model while controlling for other potential sources of variation using firsthand data for 255 plots our results indicate that both short term contracts and contracts with sowing pools push rental prices upwards we also find that soybean yields have a significant impact on land rental prices these results suggest that if argentina intends to protect the enormous natural advantage it has for agricultural production it should consider strictly regulating land rental contracts

organic certification agro ecological practices and return on investment evidence from pineapple producers in ghana the recent empirical literature on economic sustainability of certified export crops shows that certification standards that enhance yields are important for improving farm revenues and household welfare however limited evidence exists on the impact of organic certification on the adoption of agro ecological practices in this study we use unique farm level data from pineapple producers in ghana to examine the impact of organic certification on the use of agro ecological practices such as organic fertilizers organic pest and weed control crop rotation and soil and water conservation as well as how using these measures affect farm outcomes such as return on investment our empirical results reveal that organic certification increases agro ecological practice use although from a very low starting point using a generalized propensity score approach we show that there is a positive but nonlinear relationship between the intensity of agro ecological practice use and return on investment

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
