wage determination in brazil the growth of union bargaining power and informal employment this article examines wage determination in brazilian manufacturing during the 1980s and early 1990s it presents evidence to show that the reduction in state regulation of collective bargaining has led to the development of a system of wage determination which is increasingly characterised by rent sharing and insider trade union bargaining power real wages appear increasingly inflexible with respect to movements in open unemployment with a large informal sector disciplining formal sector wage bargaining and cushioning the impact of broader labour market conditions an important consequence of this is that the employment costs of a successful counter inflationary strategy may be very severe

the amenity and disamenity impacts of agriculture estimates from a hedonic pricing model the positive and negative externalities from farmland are increasingly a focus of public policy discussion about agriculture and land use a gis based hedonic pricing model shows that agricultural open space increases nearby residential property values but larger scale animal operations and mushroom production have negative impacts animal production facilities with as few as 200 animal equivalent units reduce nearby property values but larger facilities do not necessarily generate larger impacts because they tend to occur together the negative impacts of animal agriculture and the positive impacts of open space must be simultaneously modeled to avoid omitted variable bias

the importance of firm wage differentials in explaining hourly earnings variation in the large scale sector of guatemala abstract i utilize unique firm based data to examine firm wage differentials among private firms with ten or more workers in the capital area of guatemala city approximately one seventh of the overall hourly earnings variation in this sector is related to firm effects not captured by other observable characteristics of individuals and firms for most variables including observable characteristics of firms used in most previous studies the bias from not including firm fixed effects in the estimation of log wage equations is small in magnitude though statistically significant

what happens to wages after displacement faced with limited resources policymakers need to know when and where to target support for displaced workers the academic literature offers little support presenting wide ranging results with no consistent explanation for the observed differences in wages after workers are displaced in this paper we demonstrate that the heterogeneity found in the literature is consistent with varying market conditions the results suggest that support for displaced workers can be more efficiently allocated by considering the timing and location of displacement

nonparametric estimation of sample selection models sample selection models provide an important way of accounting for economic decisions that combine discrete and continuous choices and of correcting for nonrandom sampling nonparametric estimators for these models are developed in this paper these can be used for estimating shapes and important economic quantities as in standard nonparametnc regression endogeneity of regressors of interest is allowed for series estimators for these models are developed which are useful for imposing additivity restnctions that arise from selection corrections convergence rates and asymptotic normality results are derived an application to returns to schooling among australian young females is given

effects of family background on earnings and returns to schooling evidence from brazil we investigate whether omitted family background variables are responsible for high returns to schooling estimated in brazil returns to schooling fall by about one third when parental schooling is added to wage equations surprisingly the schooling of fathers in law has larger effects on wages than the schooling of fathers on the basis of a model of assortative mating we interpret this as evidence that parental characteristics represent unobservable worker attributes rather than nepotism in the labor market we conclude that the family background bias in returns to schooling is modest and need not imply returns to family connections

the economics of urban sprawl theory and evidence on the spatial sizes of cities many commentators believe that the phenomenon of urban sprawl which is characterized by vigorous spatial expansion of urban areas is a symptom of an economic system gone awry by transforming pastoral farmland into often unattractive suburbs sprawl is thought to disrupt a natural balance between urban and non urban land uses leading to a deplorable degradation of the landscape this sentiment is often translated into policy through zoning restrictions designed to inhibit the conversion of land from agricultural to urban use see bryant and conklin 1975 the economist s view of urban expansion stands in stark contrast to this emotionally charged indictment of sprawl economists believe that urban spatial size is determined by an orderly market process which correctly allocates land between urban and agricultural uses the model underlying this view which was originally developed by muth 1969 and mills 1972 and more completely analyzed by wheaton 1974 suggests that urban spatial size is determined in a straightforward way by a number of exogenous variables by showing empirically that urban size is related to the given variables population income agricultural rent and commuting cost in the manner predicted by the model the present paper achieves two goals first the empirical results suggest that the economist s view of urban sprawl is justified rather than being determined by a process which indiscriminately consumes agricultural land urban sizes are the result of an orderly market equilibrium where competing claims to the land are appropriately balanced 2 second by confirming the urban size predictions of the underlying model the empirical results constitute yet another piece of evidence validating the basic framework of urban economic analysis 3 the plan of the paper is as follows section ii sketches the structure of the muth mills model and presents the main comparative static results relevant to urban sprawl with the model s predictions in focus section iii discusses the sample and the data and section iv presents the empirical results section v offers conclusions

heterogeneous impact of soil contamination on farmland prices in the belgian campine region evidence from unconditional quantile regressions we estimate a hedonic pricing model using geo coded farmland transaction data from the campine region situated in the north east of belgium unlike previous hedonic studies we use the method of unconditional quantile regression firpo et al in econometrica 77 3 953 973 2009 an important advantage of this new method over the traditional conditional quantile regression koenker and bassett in econometrica 46 1 33 50 1978 is that it allows for the estimation of potentially heterogeneous effects of cadmium pollution along the entire unconditional distribution of farmland prices using a threshold specification of the hedonic pricing model we find evidence of a u shaped valuation pattern where cadmium pollution of the soil has a negative and significant impact on prices only in the middle range of the distribution insofar as cadmium concentrations are above the regulatory standard of 2 parts per million for agricultural land results obtained from a probit model to classify land plots into different price segments further suggest that the heterogeneous impact of soil pollution on price can be directly related to the variety of amenities that farmland provides

urban sprawl and farmland prices a theoretical model of farmland valuation is developed to explicitly account for three effects of urban sprawl conversion of farmland to urban uses effect on agricultural returns and speculative effect as represented by farmland conversion risk this model is estimated using county level data in the continental united states evidence is found for all three effects of urban sprawl on farmland values counties more accessible to major urban centers have higher net agricultural returns subsidiary evidence supports that the latter effect may be attributed to survival of or conversion to high valued agriculture around urban centers

labor earnings dynamics in a developing economy with a large informal sector abstract we study labor earnings dynamics in a developing economy with a large informal sector we use nationally representative brazilian panel data that cover both formal and informal workers we document large disparities in earnings fluctuations faced by these segments of the labor market as well as the high frequency of transitions between them informality is associated with more volatile earnings while workers in the formal sector are subject to significant downside risk transitions between formal and informal employment bring large asymmetric earnings shocks and have a frequency that depends on age and the initial earnings level

a gravity model analysis of international migration to north america this study examines the influence of political economic and demographic factors on the size and composition of migration flows to north america a modified gravity model is specified and adjusted to include immigration regulations and characteristics specific to the origin and destination countries for empirical test of the model the time period of study is from 1976 1986 and 70 countries are covered for a total of 1540 observations of migration flows to canada and the usa the results reveal that the population of origin countries and the income of destination countries are two major determinants of migration to north america high population areas of asia and latin america provided a large share of the immigrants domestic restrictions on political and civil freedom in origin countries are found to significantly impair migration to north america

estimating the demand for a new technology bt cotton and insecticide policies this article examines the potential demand for bt cotton in the southeast from information gathered in the first year of commercialization we combine revealed preference rp data on adoption of bt cotton varieties with stated preference sp data on willingness to adopt to estimate demand using a double bounded maximum likelihood procedure using estimated demand equations we simulate the costs of reducing conventional insecticide applications through subsidization of bt cotton results indicate that reducing cotton insecticide applications by 40 in the southeast would require a 21 acre subsidy with total annual program costs between 53 million and 60 million

caveat emptor cross country data on education and the labor force abstract cross country data on education and the labor force frequently are used to describe important dimensions of development and to estimate models of economic growth and growth determinants the impact of education and related phenomena this investigation finds 1 there are serious intertemporal and inter country comparability problems with these data that may importantly affect inferences about labor force size trends and productivity and schooling investments and impact 2 data gaps are systematically related to levels of development and literacy and 3 conclusions about the determinants or consequences of development based on constructed data that have been made available to fill data gaps can be seriously misleading

assessing the stability of the inter industry wage structure in the face of radical economic reforms we assess the stability of the wage structure in an economy experiencing substantial economic changes we find that the structure of inter industry wage differentials remained remarkably stable in brazil in the face of major shocks

the inconsistency of land values land rents and capitalization formulas this paper examines relationships that exist between farm income land values and capital asset pricing theory using two commonly referenced data sets it is shown that land prices and land rents do not have the same time series representations a necessary condition for the simple capital asset pricing theory to hold this suggests that a fundamental rethinking of the way in which land prices are viewed and modeled is needed more complex models that allow for rational bubbles risk aversion and future shifts in government policy or commodity prices may be required

the effects of potential land development on agricultural land prices abstract we conduct a national scale analysis of the determinants of agricultural land values the theoretical basis for the study is a spatial city model with stochastic returns to future land development the empirical model of agricultural land prices is estimated with a cross section on approximately three thousand counties in the contiguous us the results provide evidence that option values associated with irreversible and uncertain land development are capitalized into current farmland values for each county we decompose the current agricultural land value into components measuring rents from agricultural production and rents from future land development

agricultural land values and the value of rights to future land development we investigate the inuence of fu ture land development on current agricultural land values from a theoretical model of land markets we derive a reduced form expression for agricultural land values in terms of observable variables this result dictates the speci cation of our econometric model and we nd strong sup port for the model in an application to new york state the estimated model together with a spa tial interpolation algorithm is used to generate a surface of estimated development rights values for orange county this approach overcomes several problems that arise with the use of stan dard appraisal methods to value conservation easements jel q24

housing market bust and farmland values identifying the changing influence of proximity to urban centers this article estimates the impact of the 2007 2008 residential housing market bust on farmland values using parcel level farmland sales data from 2001 2010 for a 50 county region under urbanization pressure in western ohio hedonic model estimates reveal that farmland was not immune to the residential housing bust the portion of farmland value attributable to proximity to urban areas was almost cut in half shortly after the bust in 2009 2010 nonetheless total farmland prices remained relatively stable in the 2000s likely due to increased demand for agricultural commodities our results are robust to different assumptions about the structure of the unobserved spatial correlation

school expenditures and post schooling earnings evidence from high school and beyond studies based on inputs measured at the state level generally report that school expenditures have substantial effects on students adult wages whereas studies based on less aggregated measures report small effects the author uses wage data from high school and beyond to analyze this discrepancy and to estimate the effect of school expenditures on students post schooling earnings the author finds that the discrepancy in the literature stems mostly from two factors measurement error in district level expenditures and omitted state effects in the earnings regression the author also finds that the effect of school expenditures on earnings is significant but small a 10 increase in school spending would increase students adult wages by only 0 68 copyright 1996 by mit press

potential for private cost increasing technological innovation under a tax based economic incentive pollution control policy a criticism of the current pollution control policy is its lack of incentive for technological innovation the author argues that the implementation of a tax based economic incentive policy may have its pay off in terms of lower real control outlays but this makes it possible for total private compliance costs resource costs and tax or transfer costs to actually increase upon the introduction of some new less expensive control technologies he presents a numerical illustration of this phenomenon then derives the conditions under which such cost increases may occur cost increasing technological innovations could generally be avoided if the tax incentive is coupled with a net revenue lid for the pollution control authorities 4 references 3 tables

the impact of primary schooling on economic development a review of the evidence abstract the contribution of primary schooling to economic development is greater than has conventionally been percieved this review of recent research shows that primary schooling increases labour productivity in both urban and rural sectors and that the economic returns to such investment are typically high in addition it reduces fertility improves health and nutrition and promotes other behavioural and attitudinal changes which are helpful to economic development investment strategies which give primary schooling an important place would be more conducive of growth with equity than many alternatives priorities for government and donor policies are indicated as are those for future research

agri environmental policy and urban development patterns a general equilibrium analysis this paper investigates the spatial effects that the provision of environmental public goods have on residential location choices in a suburban context specifically a spatial general equilibrium framework is developed to analyze the consequences of adopting an agri environmental policy promoting the provision of positive farming externalities we use a static monocentric model of an open city where agricultural bid rents and agricultural amenities vary endogenously in space and where the positive externalities associated with agricultural production are valued by households consistent with empirical evidence of the potential side effects that conservation policies may have in terms of urbanization patterns and land price changes we show that under certain conditions implementing an agri environmental policy may promote additional suburban development moreover we demonstrate that the emergence of disconnected suburban areas may be significantly influenced by the location of land regulated by an agri environmental policy finally we discuss distributional aspects and show that while introducing an agri environmental policy has a negative impact on most residential land value it can have positive effects on farmland and residential land located within the regulated areas suggesting the non neutrality of such policies regarding the agents assets

the impacts of the tax deferred exchange provision on farm real estate values this study examines the effects of the section 1031 tax deferred exchange provision on agricultural land values the provision allows taxpayers to defer taxation for relinquished productive assets if a like kind asset is acquired within the allotted time of 180 days the analysis examines a set of 3 580 farm real estate transaction from 55 agricultural counties in indiana over the period 2003 2006 hedonic price analysis suggests that properties acquired under a like kind exchange are associated with a 1 32 price premium jel h23 q15

evidence on the validity of cross sectional and longitudinal labor market data this article investigates error properties of survey reports of labor market variables we use the panel study of income dynamics psid validation study a two wave panel survey of workers employed by a large firm that shared its detailed payroll records individuals reports of annual earnings are fairly accurate errors are negatively related to true earnings reducing bias due to measurement error when earnings are used as an independent variable biases are moderately larger for changes in earnings earnings per hour are less reliably reported than annual earnings biases in estimating earnings functions are relatively small but those in labor supply functions may be important

the structure of worker compensation in brazil with a comparison to france and the united states abstract we employ comprehensive linked employer employee data for brazil to analyze wage determinants and compare results to abowd et al 2001 for french and u s manufacturing while returns to human capital in brazilian manufacturing exceed those of the other countries occupation and gender differentials are similar the worker characteristics component accounts for much of the greater wage inequality in brazil but the establishment fixed component has scant explanatory power thus firm or industry level factors offer little scope for explaining the differences in wage inequality brazil s wage structure resembles that of france a country with some similarity in labor market institutions

public inputs and child schooling in brazil household data from a one percent sample of the 1970 brazilian census are used to analyze the effect of public inputs i e the supply of schooling on children s school attainment in brazil the household data are combined with measures of school availability and quality derived directly from the same census data the measures are based on the number and education of schoolteachers in each of 169 different areas of the country elasticities of demand with respect to these public inputs are estimated these elasticities are high in both rural and urban areas in urban areas the positive effect of public inputs is greater for children from households with poorer and less educated parents in rural areas the positive effect of public inputs is greater if anything for children from households that are relatively better off at least compared to other rural households

the impact of global warming on agriculture a ricardian analysis reply we measure the economic impact of climate on land prices using cross sectional data on climate farmland prices and other economic and geophysical data for almost 3 000 counties in the united states we find that higher temperatures in all seasons except autumn reduce average farm values while more precipitation outside of autumn increases farm values applying the model to a global warming scenario shows a significantly lower estimated impact of global warming on u s agriculture than the traditional production function approach and in one case suggests that even without co sub 2 fertilization global warming may have economic benefits for agriculture 16 refs 5 figs 5 tabs

wage differentials in brazil theory and evidence the investigation of wage determination and wage differentials in developing countries has concentrated on the effects of human capital and different sources of segmentation associated with institutional arrangements and structural characteristics on earnings in this article we use micro data for brazil for the 1980s and 1990s to test several competitive theories and models with segmentation explained by efficiency wages we find that unmeasured abilities and efficiency wage models seem to play a role in wage determination while compensating differentials and transitory difference theories were found to be irrelevant to wages formation

linking the price of agricultural land to use values and amenities the recent appreciation in agricultural land values across the united states has raised a number of important questions for farmers farmland owners lenders and policy makers while traditional economic theory suggests that farmland values are determined by the discounted stream of expected returns previous research has shown that agricultural land values are actually driven by a complex set of factors this study leverages the unique characteristics of a national land based usda survey on farmland values and cash rents to estimate broad national level determinants of the market value of cropland and pastureland our results support past research findings that indicate farmland values are only partially explained by agricultural returns we find that multiple nonagricultural attributes of farmland also contribute to the market value

a human capital model of the effects of ability and family background on optimal schooling levels this paper develops a theoretical model of optimal schooling levels where ability and family background are the central explanatory variables we derive schooling demand and supply functions based on individual wealth maximization using nlsy79 data we stratify our sample into one year fte work experience cohorts for 1985 1989 mincer s 1974 overtaking cohort the years of work experience at which individuals observed earnings approximately equal what they would have been based on schooling and ability alone corresponds to 13 fte years of work experience yielding on average a rate of return of 9 6 percent and an average optimal 11 4 years of schooling

labour market impacts of school expenditure and class size evidence from china this study is a first attempt to estimate the impact of school resources on students subsequent labour market earnings in china combining unprecedented school data from the early 1950s to the 199

effect of urban proximity on agricultural land values this article seeks to more accurately estimate the size and distance of the effect of urban proximity on agricultural land values the econometric model lets the size and distance of the effect of urban proximity on agricultural land values vary by population real income and time the changes in the effect of urban proximity over time can be largely explained by population and income thus there does not appear to be a shift in preferences toward living further from the city center

premiums to employment in larger establishments evidence from peru abstract examination of the employer size wage effect for males in urban peru suggests the following higher wages in larger establishments do not merely compensate for higher worker quality or inferior working conditions size differences in the use of rising wage tenure profiles cannot provide a market clearing explanation for the employer size wage effect unless workers are extremely impatient thus larger employers appear to pay premiums unionization explains none of the premiums and minimum wage compliance explains at best a small fraction shirking based efficiency wage explanations for premiums are implausible because peruvian job security legislation greatly inhibits dismissals in larger establishments explanations meriting further research involve the use of high wages to reduce turnover and to improve productivity enhancing morale

confucius institute s effects on international travel to china do cultural difference or institutional quality matter abstractthis article uses a panel data of china s inbound tourist flows from 2005 to 2015 to investigate confucius institute ci s influence on china s tourism we find that ci as a comprehensive platform for china s foreign cultural exchange has a significant positive effect on china s tourist flows the effects of ci on china s inbound tourism are transmitted through bridging cultural gaps and promoting chinese language which reduces psychic distance and transaction costs ci also stimulates china s inbound tourist flows via reducing information asymmetry caused by different levels of institutional quality interestingly we find that the heterogeneous effects of ci on china s inbound tourism depend on institutional quality and the effects of ci to boost china s tourists are more prominent in departure countries with larger cultural difference

employee spinoffs and other entrants stylized facts from brazil using a comprehensive linked employer employee database from brazil for the period 1995 2001 we are able for the first time to compare firms founded as employee spinoffs to new firms without parents and to diversification ventures of existing firms entering a new industry employee spinoffs are defined either as the director manager having moved from a parent in the same industry or as one quarter of the employees having shifted from a common parent depending on definition employee spinoffs account for between one sixth and one third of the new firms in brazil s private sector during this period regardless of definition size at entry is larger for employee spinoffs than for new firms without parents but smaller than for diversification ventures of existing firms similarly exit rates for employee spinoffs are less than for new firms without parents and comparable to those for diversification ventures of existing firms these results suggest that we can think of some part of a firm s productivity draw in the jovanovic 1982 model as embodied in the firm s employees and portable by them to a new firm

examining the use of national databases in a hedonic analysis of regional farmland values hedonic techniques have attracted the interest of economists as a means of measuring values of nonmarket goods by studying the market transactions of differentiated products such as automobiles and houses implied values and corresponding demand schedules can be estimated for underlying characteristics such as automobile safety features two car garages and air quality of residential neighborhoods the subject of this paper is farmland and estimating the values of characteristics such as soil productivity and erodibility in 1974 rosen and freeman independently developed theoretical models for differentiated consumer products that now serve as the basis for empirical estimates of marginal prices of product characteristics procedures to estimate demand schedules of underlying characteristics were outlined in palmquist 1984 palmquist 1989 further extended rosen s theoretical model to consider land as a differentiated factor

integrated longitudinal employer employee data for the united states the development of a database infrastructure that captures the complex interactions among households and businesses at the microeconomic level and characterizes the dynamics of the modern economy is critical for the social sciences the creation of such an infrastructure has posed a major challenge to national statistical institutes since most institutes collect store and disseminate data on the engines of economic growth businesses and households in twin data silos proposals to integrate the two face technical monetary legal and policy obstacles that go far beyond the norm of datacollection activities recent efforts at the longitudinal employer household dynamics lehd program at the u s census bureau have finally made this critical data infrastructure achievable and accessible the potential uses of longitudinal integrated employer employee data are far reaching a partial list includes the effect of technological and structural change on earnings employment and productivity the analysis of the firmspecific contribution to pay the effect of firm wage setting and turnover policies on productivity the impact of firm policies on different groups of workers e g welfare recipients the effect of firm expansion exit and relocation decisions on neighborhood demographic composition the analysis of worker commuting patterns and mobility and a full accounting of the

estimating the gravity model without gravity using panel data this article examines the effects of zero trade on the estimation of the gravity model using both simulated and real data with a panel structure which is different from the more conventional cross sectional structure we begin by showing that the usual log linear estimation method can result in highly deceptive inference when some observations are zero as an alternative approach we suggest using the poisson fixed effects estimator this approach eliminates the problems of zero trade controls for heterogeneity across countries and is shown to perform well in small samples

globalization and formal sector migration in brazil summary comprehensive linked employer employee data allow us to study the relationship between domestic formal sector migration in brazil and globalization considerable worker flows in the formal labor market during 1997 2001 are directed toward lower income regions the reverse flows of those often posited for informal labor markets estimation of the worker s multi choice migration problem shows that previously unobserved employer covariates are significant predictors associated with migration flows these results support the idea that globalization acts on internal migration through job stability at exporting establishments and employment opportunities at locations with a concentration of foreign owned establishments a 1 increase in exporter employment predicts a 0 3 reduced probability of migration a 1 increase in the concentration of foreign owned establishments at potential destinations is associated with a 0 2 increase in the migration rate

land price volatility in a geographically dispersed market historical evidence and theory lead to a hypothesis that land price variation increases with distance to market this hypothesis is tested with county data from five cornbelt states during the period 1969 to 1987 when price changes were unusually large our data support the hypothesis in the 70s prices increased more in the western cornbelt than in the eastern cornbelt in the 80s the western cornbelt experienced the more precipitous price declines our hypothesis explains why great plains farmers have experienced greater financial problems during times of stress than have many other farmers

implicit prices of soil characteristics for farmland in iowa arguments have long persisted that purchasers pay too much for poor land i e less productive more erosive relative to the higher quality counterpart in other words purchasers are either irrational or poorly informed relative to the differences in land productivity between poor and good farmland similar arguments have been advanced concerning the willingness to pay rent on the part of tenant operators little empirical evidence exists to support or reject this hypothesis farmland appraisals are sometimes cited as evidence to support the contention but such empiricism may indicate more about the quality and biases of appraisers than about the behavior or efficient functioning of the farmland market resolution of this issue is extremely important to the formation of soil conservation policy designed to protect soil productivity irrational behavior on the part of land purchasers may lead one to infer that the market system is failing to recognize adequately the soil productivity consequences of soil erosion if this oversight consistently leads to excessive soil erosion from society s perspective then some form of government intervention may be necessary to protect the welfare of society assuming that such intervention is capable of correcting the market failure

the stochastic city abstract this paper analyzes a simple model of an urban area with growth and uncertainty household income rents and prices for land follow stochastic processes even though investors are risk neutral uncertainty affects both land rents and land prices in equilibrium because the conversion of land from agricultural to urban use is irreversible growth on the other hand affects urban and agricultural land prices but not the level of rents we show that uncertainty i delays the conversion of land from agricultural to urban use ii imparts an option value to agricultural land iii causes land at the boundary to sell for more than its opportunity cost in other uses and iv reduces equilibrium city size

do agricultural land preservation programs reduce farmland loss evidence from a propensity score matching estimator more than 80 governmental entities concerned about sprawl open space and farmland have implemented purchase of development rights pdr programs preserving 2 23 million acres at a cost of 5 47 billion are pdr programs effective in slowing the rate and acres of farmland loss employing propensity score matching methods and a 50 year 269 county data set for six mid atlantic states we find empirical evidence that pdr programs have had a statistically significant effect on farmland loss having a pdr program decreases a county s rate of farmland loss by 40 to 55 and decreases farmland acres lost by 375 to 550 acres per year

the regulation of labor author s botero juan djankov simeon la porta rafael lopez de silanes florencio shleifer andrei abstract we investigate the regulation of labor markets through employment collective relations and social security laws in 85 countries we find that the political power of the left is associated with more stringent labor regulations and more generous social security systems and that socialist french and scandinavian legal origin countries have sharply higher levels of labor regulation than do common law countries however the effects of legal origins are larger and explain more of the variation in regulations than those of politics heavier regulation of labor is associated with lower labor force participation and higher unemployment especially of the young these results are most naturally consistent with legal theories according to which countries have pervasive regulaory styles inherited from the transplantation of legal systems

labor force participation and earnings determinants for women in the special conditions of developing countries abstract little systematic analysis exists regarding hypothesized special labor market conditions for women in developing countries this study explores such conditions in nicaragua major results are i small children affect participation less than in developed countries due to child care from extended families or while on informal sector jobs and the necessity for poor mothers to work ii schooling and experience have major roles affecting work sector and earnings but the primary school return is half that cited by the world bank iii other human capital variables particularly nutrition have some impact

the changing roles of urban influence and agricultural productivity in farmland price determination between 2000 and 2010 inflation adjusted u s farmland values increased by over 80 this period of rapid price appreciation coincided with both the agricultural commodity price boom and the broader financial crisis this paper examines the degree to which the determinants of farmland prices changed over this period using a panel of farmland transfer declarations from 98 illinois counties hedonic price analysis demonstrates that the relative importance of urban influence decreased over this period while the relative importance of agricultural productivity increased the study carries important implications for farmers farmland owners and policy makers

the southern wage gap human capital and the quality of education this suggests that school quality can play an important role in explaining the racial wage gap welch 28 and smith 19 both provide anecdotal evidence that relates the narrowing of school quality to the falling racial gap in earnings the rising rate of return for black workers on years of school documented by weiss and williamson 27 welch 28 and smith and welch 20 also is consistent with the improving quality of their education nevertheless school quality has not been incorporated into systematic statistical analysis of the racial wage gap this is the main focus of this paper i examine 15 southern states which had data on the segregated white and black school systems i have attempted to link the demonstrated lower quality of education during segregation in the south to the persistent southern wage gap in addition i have tried to

trade institution quality and income inequality summary we examine the effect of trade on income inequality in small developing countries we use two well accepted trade cost variables for identification one is based on baltic dry index and another is commodities price index our main finding is that trade leads to a significant reduction increase in income inequality in autocracies democracies to explain such different effects we provide supporting evidence that autocracies export more primary commodities and may follow the stolper samuelson theorem in ho framework while democracies active in manufacturing outsourcing may follow feenstra and hanson 1996 task model

the joint influence of agricultural and nonfarm factors on real estate values an application to the mid atlantic region county level farmland and residential housing values are estimated for the mid atlantic region as a function of farm returns developed land values household incomes population densities and location results are based on the hypothesis that farmland owners anticipate land development and that nonfarm factors are important determinants of farmland prices response of farmland prices to change in farm returns is found to be inelastic and relatively uniform in rural and urban counties response to nonfarm factors is found to be more elastic and substantially greater in rural counties copyright 2001 oxford university press

the fundamentals of land prices and urban growth abstract in a very simple model in which capital is durable and landowners have perfect foresight the price of urban land has four additive components the value of agricultural land rent the cost of conversion the value of accessibility and the value of expected future rent increases a growth premium in rapidly growing cities the growth premium may easily account for half of the average price of land and may create a large gap between the price of land at the boundary minus conversion cost and the value of agricultural land rent

the impact of global warming on agriculture reply in our paper with daigee shaw mendelsohn et al 1994 henceforth mns we developed a new approach to measuring the impact of global warming on agriculture we call this approach ricardian because it relies upon standard rent theory as a way of identifying the impact of changes on net economic welfare we compared the ricardian approach with the traditional production function approach which uses agricultural production functions but has great difficulty identifying all the other adjustments that farmers make in response to changing external conditions the ricardian approach is particularly well suited to a tremendously heterogeneous sector because it can rely upon reduced form estimation and does not require the impossible task of constructing structural models of hundreds of crops in thousands of locations estimating the model using cross sectional data on climate farm land prices and other economic and geophysical data for almost 3 000 counties in the united states the ricardian approach shows a significantly lower estimated impact of global warming than the traditional productionfunction approach indeed our preferred statistical approach showed modest benefits of climate change in his comment on mns in this issue of the review william r cline 1996 raises three concerns first he notes that the analysis assumes that output prices remain constant second he asserts that the analysis assumes that the supply of water for irrigation is perfectly elastic third he calls for testing the results of the model on alternative climate scenarios from general circulation models gcm s his first and third points are useful additions while the second is incorrect our ricardian approach assumes that the existing pattern of agricultural land rents and land prices reflects the long run equilibrium economic effect of climate and other geophysical and economic variables standard economic reasoning shows that by calculating the estimated effects of perturbing the climatic variables we can project the impact of climate change on economic welfare we do so in a partial equilibrium approach which assumes that output prices are invariant to the climate and cline is correct to point out that this might lead to biased estimates because the partialequilibrium estimates tend to underestimate damages and overestimate benefits in fact the bias is small given standard parameters for agricultural demand and supply functions we illustrate this point using linear supply and demand functions for agricultural crops let demand be given by qd ao a1p while supply is q po pi p where q and p are output and price and ai and i are parameters in equilibrium at the old climate market outcomes are qo and po now suppose that global warming contracts supply so that

the effects of education and family planning programs on fertility in indonesia abstract numerous studies indicate that female education is a major determinant of fertility and that the estimated effects are large relative to other variables including family planning program variables there are however two serious deficiencies in the research relating educational attainment to fertility that could give rise to invalid inferences first many public programs including health and family planning programs may influence a woman s decisions about education and these indirect programmatic effects might be large second nearly all existing studies of the impacts of education on fertility assume that a woman s educational attainment is exogenous education could be serving as a proxy for such unobservable determinants as ability motivation and parental background as these factors most likely are important determinants of a woman s educational attainment we use the 1993 indonesian family life survey to compare the estimated impacts of education on fertility from a simple model tha

international comparisons of rural urban educational attainment data and determinants we study cross country differences in rural and urban educational attainment by using a data set comprising 56 countries we focus on the determinants of rural urban educational inequality which is measured by the ratio of rural to urban average years of schooling within each country we find that riskier human capital investment less credit availability a colonial heritage a legal system of french origin and landlockedness of nations are all associated with relatively lower rural educational levels and greater rural urban educational inequality conversely larger formal labor markets better infrastructure and a legal system of british origin are associated with relatively higher rural educational levels and lower rural urban educational inequality we also identify an interaction effect between economic development level and some of these factors in particular we find that as development level increases the negative positive relationship between french british legal systems and rural urban educational inequality is reversed and becomes positive negative

schooling and earnings distributions with endogenous labour force participation marital status and family size this paper investigates the impact of various schooling investment strategies on family and per capita earnings within a framework that integrates effects on earnings family size marital status and labour force participation data are from a 1977 1978 survey of urban nicaraguan women aged 15 45 excerpt

the quality of schooling quantity alone is misleading although much research discusses the quantity of schooling as an effective impact on productivity and earnings most such research leaves out the idea of the quality of schooling which may cause biases in the estimated returns to schooling this paper consequently attempts to extend the standard mincerian approach to incorporate school quality as well as quantity it demonstrates how exclusion of quality in the standard procedure may cause biases in the estimated returns to years of schooling probably in the upward direction the paper explores the implications of this extension of the standard model for the case of young brazilian males it shows that the estimate of the private return to years of schooling using the preferred quality inclusive specification is only one half the estimate using the standard procedure indicating substantial upward bias in the standard estimates it further outlines a method for estimating a social return to quality and finds that it exceeds substantially the social return to quantity the paper then shows why this in turn suggests there may be an equity productivity trade off in schooling investments

government intervention efficiency wages and the employer size wage effect in zimbabwe abstract this paper uses matched employer employee data from a survey of 201 manufacturing firms and 1609 of their workers conducted in zimbabwe in the summer of 1993 the results indicate that there is a substantial premium associated with employment in larger firms and that this premium cannot be explained by differences in worker quality and job characteristics nor is it eliminated by controlling for unionization minimum wages or other forms of government intervention the size premium is much larger for white collar than for blue collar workers these differentials are also found to be substantially larger than those estimated for other developed and developing countries the analysis uses the data about firm characteristics to explore a number of efficiency wage based explanations of the size differential and finds results which are consistent with but not conclusive proof of hiring turnover and morale based notions of efficiency wages

labor turnover and labor legislation in brazil one of the main characteristics of the brazilian labor market is its impressively high job and worker turnover rates although labor legislation in brazil is very restrictive dismissal costs are not high when compared with other latin american countries moreover many authors argue that the design of some job security programs creates perverse incentives that generate labor turnover the objective of this paper is twofold first we describe brazilian labor legislation with emphasis on job security provisions and their incentives on workers reallocation then after reviewing the most recent evidence on labor turnover in brazil we investigate the effects of changes in job termination costs implemented in the 1988 constitution and in a labor law of september 2001 on employment duration both legislation changes increased firing costs and should have therefore reduced turnover for formal workers affected by them a simple differences in differences methodology is applied to monthly individual data from pesquisa mensal de emprego pme ibge which has information on previous employment spells for those currently unemployed the results establish that both changes reduced turnover for formal workers affected by the legislation a significant increase in average employment duration of affected workers relative to not affected workers was observed after both legislation changes we also provided evidence that the 1988 constitutional change reduced the probability of fake layoffs although there are still a high number of such agreements being made between workers and their employers
