a theoretical and empirical analysis of family migration and household production reply of her household production as factors in the family s migration decisions 38 in this paper the research on family migration will be extended in three ways a formal model of household production and family migration will be developed and used to generate testable hypotheses about family migration variables which otherwise would not have a clear economic interpretation are incorporated into the model the model will then be estimated and some policy implications will be discussed one policy implication concerns the efficiency of the labor market labor market efficiency needs to be judged not only in terms of the efficiency of the job search of single individuals but also in terms of the efficiency of the joint job search of double income families this paper is organized into five sections first a comparative static household production model of locational choice is developed 2 next this model of locational choice is used to develop a theoretical model of family migration third the data and empirical model are discussed fourth the empirical results are reported and interpreted in terms of three different types of migration estimates of the impact of selected variables on the distance of the move are also considered the final section summarizes the general findings and offers some policy implications

a simple estimator for simultaneous models with censored endogenous reggressors this paper presents a simple two step estimator for models with censored endogenous regressors and sample selection bias the approach unifies the literature on censored endogenous regressors and sample selection bias and provides extensions the procedure employs generalized residuals to adjust for the inconsistency caused by the endogeneity of the censored regressors the paper also provides two new tests of weak exogeneity an empirical example examining the trade off between fringe benefits and wages indicates that the estimation procedure works well a monte carlo experiment suggests that the proposed tests have good power properties copyright 1993 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

overeducation regional labor markets and spatial flexibility for most workers access to suitable employment is severely restricted by the fact that they look for jobs in the regional labor market rather than the global one in this paper we analyze how macrolevel opportunities regional market characteristics and microlevel restrictions the extent to which job searchers are restricted to the regional market can help to explain the phenomenon of overeducation we use a two step procedure to control selective access to employment the results show that the size of the labor market is an important factor in avoiding overeducation

gender differences in overeducation a test of the theory of differential overqualification there is little question that substantial labormarket differences exist between men and women among the most researched difference is the male female wage gap many different theories are used to explain why men earn more than women one possible reason is based on the limited geographic mobility of married women robert frank 1978 family mobility is a joint decision in which the needs of the husband and wife are balanced to maximize family welfare job motivated relocations are generally made to benefit the primary earner in the family this leads to a constrained job search for the secondary earner as he or she must search for a job in a limited geographic area since the husband is still the primary wage earner in many families the job search of the wife may suffer individuals who are tied to a certain area are labeled tied stayers while secondary earners who move for the benefit of the family are labeled tied movers jacob mincer 1978 the wages of a tied stayer or tied mover may not be substantially lower if the family lives in or moves to a large city if a large labor market has more vacancies the wife may locate a wage offer near the maximum she would find with a nationwide job search however being a tied stayer or tied mover can lower the wife s wage if the family lives in or moves to a small community a small labor market will reduce the likelihood of her finding a job that utilizes her skills as a result she may accept a job for which she is overqualified and thus earn a lower wage this hypothesized relationship between the likelihood of being overqualified and smsa size is termed differential overqualification frank 1978 and haim ofek and yesook merrill 1994 provide support for the theory of differential overqualification by finding that the malefemale wage gap is greater in smaller smsa s while the results are consistent with the existence of differential overqualification they may also result from other situations as well firms in small labor markets may use their monopsony power to keep wages down 2 local demand shocks are found to be a major source of wage variation both across and within local labor markets robert topel 1986 since large labor markets are generally more diversified a demand shock can have a substantial impact on immobile workers in small labor markets another reason for examining differential overqualification involves the assumption that there are more vacancies in large labor markets while there is little doubt that more vacancies exist in large labor markets there are also likely to be more people searching for jobs in large labor markets if the greater number of vacancies is offset by the larger number of searchers it is unclear whether women will be more likely to be overqualified in small labor markets instead of relying on wages to determine if differential overqualification exists we consider an explicit form of overqualification based on education

interprovincial migration and local public goods the objective of this paper is to test whether fiscally induced migration occurs in canada that is whether interprovincial migration flows are influenced by government tax and expenditure policies in order to do so a multinominal logit model of migration is developed in which individuals choose to live in the province where their utility would be highest the model is estimated using aggregate data for the period 1962 81 the results indicate that migration is influenced by provincial government spending trough the magnitude and direction of the effect differs with the type of government spending the implication of these results is that intergovernmental transfer payments and provincial natural resource revenues also have the potential to influence migration flows in canada summary in fre excerpt

estimating demand for local telephone service with asymmetric information and optional calling plans in this paper i study the theoretical and econometric implications of agents uncertainty concerning their future consumption when a monopolist offers them either a unique mandatory nonlinear tariff or a choice in advance from a menu of optional two part tariffs agents uncertainty is resolved through individual and privately known shocks to their types in such a situation the principal may screen agents according to their ex ante or ex post type by offering either a menu of optional tariffs or a standard nonlinear schedule the theoretical implications of the model are used to evaluate a tariff experiment run by south central bell in two cities in kentucky in 1986 the empirical approach explicitly accounts for the existence of informational asymmetries between local telephone users and the monopolist leading to different nested econometric specifications under symmetric and asymmetric information the empirical evidence suggests that there exists a significant asymmetry of information between consumers and the monopolist under both tariff regimes all expected welfare components failed to increase with the introduction of optional tariffs for the estimated value of the parameters copyright 2002 wiley blackwell

from plan to plant effects of certification on operational start up in the emergent independent power sector in this paper we study the transition from planned venture to operational start up in the emergent independent power sector planned ventures face tremendous obstacles in assembling the resources necessary to begin operations we hypothesize and show that formal certification from authorized actors increases the likelihood of making this transition moreover we find that the effects of certification are contingent on the legitimacy of the sector as a whole certifications have a stronger effect on start ups when sector legitimacy is low than when it is high this research helps us understand a rarely studied organizational transition from entrepreneurial intention to actual operations within nascent sectors it directs attention to the legitimating effects of formal certification highlights the importance of a multilevel approach to legitimacy and contributes to the growing rapprochement between entrepreneurial studies and institutional theory

the effects of job relocation on spousal careers evidence from military change of station moves we investigate the impact of military job relocation on spousal earnings and employment by creating a unique longitudinal database that tracks over 900 000 military spouses over the period 2001 2012 based on data from two administrative sources military records on personnel and their dependents and social security earnings records this database allows us to estimate the effects of military change of station moves controlling for some key observable characteristics of the service member and household and controlling for individual spouse fixed effects we find that military moves cause a substantial decline in spousal earnings in the year of the move on the order of 2 100 or 14 of average spousal earnings moves also increase the likelihood that the spouse has no earnings for the year we find larger earnings reductions for moves that cross state lines and for older spouses male spouses and those with young children the career costs persist over time and spouses continue to experience significantly lower earnings 2 years after the move this persistence combined with the typical military member experiencing a change of station move every 2 or 3 years may substantially limit the ability of military spouses to accumulate human capital over time jel h56 r23 j45 j16 j64

labor immobility and the formation of gender wage gaps in local markets family ties have an important effect on the wage gap between male and female workers because wives are often more geographically tied to their husband s location which may not be the best market for the wife s skills theory implies a testable inverse relationship between urban size reflecting labor market size and male female wage differentials our results indicate that the wage gap between married men and women narrows with urban size about 17 percent of the wage gap between married men and women can be accounted for by urban size or more fundamentally by geographic immobility due to the family tie constraint

why are power couples increasingly concentrated in large metropolitan areas using the panel study of income dynamics psid we test costa and kahn s colocation hypothesis which predicts that power couples couples in which both spouses have college degrees are more likely to migrate to the largest cities than part power couples or power singles we find no support for this hypothesis instead regression analyses suggest that only the education of the husband and not the joint education profile of the couple affects the propensity to migrate to large metropolitan areas the observed location trends are better explained by higher rates of power couple formation in larger metropolitan areas

housing tenure job mobility and unemployment in the uk this article examines the effects of housing tenure on individuals job and unemployment durations in the uk we examine job to job transitions and transitions from unemployment we take account of whether or not the arrival of a job was synonymous with a non local residential move tenure endogeneity and unobserved heterogeneity we find that home ownership is a constraint for the employed and public renting is more of a constraint for the unemployed employed home owners have a lower transition into employment with a distant move and unemployed public renters have a lower probability of gaining employment in more distant labour markets the nature of housing tenure has long been blamed for discouraging spatial mobility and thereby having an impact upon labour market outcomes in the early 1980s in the uk the main culprit was deemed to be local authority housing mccormick 1983 hughes and mccormick 1981 1987 examined the longer distance migration rates of those in local authority housing and found that they had lower longer distance migration rates compared to both owner occupiers and those in private rented accommodation although the latest research suggests that these effects may have lessened hughes and mccormick 2000 the relative immobility of public renters may stem from public housing rents being below market rates the restricted transferability within public housing high waiting lists and security of tenure public renters are then locked in and face higher costs if they accept a job that involves a long distance move more recently the blame has been pinned on private home ownership oswald 1996 1999 in a series of papers using macro time series and cross section data for oecd countries and regions within a number of those countries has argued that home own ership causes unemployment one explanation revolves around the reduced mobility of home owners relative to private renters owing to the costs of buying and selling homes subsequent and arguably more sophisticated micro econometric tests have placed doubt upon the alleged relationship coulson and fisher 2002 for the us find that unemployment duration is shorter for home owners relative to renters though neither is unobserved heterogeneity nor the endogenous nature of housing tenure accounted for van leuvensteijn and koning 2004 do account for the endogeneity of home ownership and find using dutch data that employed home owners are less likely to become unemployed relative to employed renters more recently munch et al 2006a using danish data find shorter unemployment spells amongst home owners compared to renters after controlling for the endogeneity of home ownership

lifetime earnings and the training of young men in britain a model is estimated in which the type of training undertaken is determined by the predicted lifetime earnings for each type of training personal factors and educational attainment lifetime earnings has a positive and significant effect on the allocation of individuals across training types the impact is variable a 10 rise in own lifetime earnings raises the fraction undertaking off the job training by up to 0 059 but the fraction undertaking no training by as little as 0 017 if the government were to pay an annual grant of 3000 to apprentices for 3 years the proportion of apprentices in the sample would increase from 28 to 30

why have urban poverty and income inequality increased so much argentina 1991 2001 abstract this article analyzes the trends in income inequality and poverty among argentine households during the nineties we assess the effect of changes in labor force participation unemployment educational levels and returns to individual characteristics on income inequality and poverty by using a microsimulation approach we found that unemployment accounts for a large part of the increase in income inequality and poverty experienced in the past decade changes in labor force participation had an equalizing effect over the whole period while changes in the returns to workers sociodemographic characteristics could be associated with a small increase in income inequality with respect to poverty unemployment affected negatively the proportion of households below the poverty line amplified the poverty gap and increased the severity of poverty in contrast changes in labor force participation are associated with a reduction in the poverty rate

individual and opportunity factors influencing job creation in new firms we build on multiple theoretical perspectives to investigate the unique and joint effects of individual and opportunity level factors affecting job creation in new firms we tested hypotheses using survey data from individuals who transitioned from unemployment to self employment under the auspices of a german public policy program our findings reveal that an entrepreneur s breadth of knowledge has a negative influence on the firm s job creation whereas the entrepreneur s leadership experience has a positive influence however as the sector specific labor requirements of a business opportunity increase both breadth of knowledge and leadership experience allow founders to operate their firms with fewer employees

bargaining and distribution in marriage the standard economic model of the family is a common preference model that assumes that a family maximizes a single utility function and implies that family behavior is independent of which individuals receive income or control resources in recent years this model has been challenged by game theoretic models of marriage that do not impose pooling and are therefore consistent with empirical evidence that income controlled by husbands and wives does have different effects on family behavior in this paper the authors review a number of simple bargaining models and relevant empirical evidence and discuss their implications for distribution within marriage

trade protection and industry wages in india this paper examines the link between trade protection and industry wage premia in india using a unique dataset combining employment survey data with industry level data for various years between 1983 and 2000 the author finds that india s trade reforms were not distributionally neutral the impact of protection on industry wage premia was positive and statistically significant though modest in magnitude workers employed in industries with high tariffs received higher wages than apparently identical workers in low tariff industries because industries with high initial levels of protection were also those with the largest tariff reductions during this period and had the highest share of unskilled workers the positive tariff wage effect implies that the trade reforms were likely to have increased wage inequality as the relative wages of the predominantly unskilled workers in these manufacturing industries fell

the impact of surplus schooling on productivity and earnings this article examines the impact of surplus schooling on individual productivity and earnings it proposes a model that divides workers education into two components education that is required and thus fully utilized in the job and education that exceeds the amount required and thus may be underutilized in the job the model is tested with data from the 1969 1973 and 1977 quality of working life surveys quinn and staines 1979 required schooling for each occupation is derived from estimates by job incumbents and by the dictionary of occupational titles the results show thqt surplus or underutilized education is rewarded at a lower rate than required education with the actual return dependent on the type of job

regional sorting of human capital the choice of location among young adults in sweden berck p tano s and westerlund o regional sorting of human capital the choice of location among young adults in sweden regional studies migration rates are highest among young adults especially students and their location choices affect the regional distribution of human capital growth and local public sector budgets using swedish register data on young adults the choice of whether to enrol in education and the choice of location are estimated jointly the results indicate a systematic selection into investment in further education based on school grades and associated preferences for locations with higher per capita tax bases for students the estimates indicate lower preferences for locations with higher shares of older people the importance of family networks for the choice of location is confirmed

the supply of child care labor this article presents estimates of the elasticity of supply of labor to child care this parameter is an important determinant of the effects of child care subsidies and regulations on the cost of child care using data from the current population survey there is evidence of an elasticity in the range of 1 2 1 9 this implies that the majority of the benefits of child care subsidies accrue to consumers of child care it is also consistent with the fact that child care workers wages remained flat in real terms in recent years despite rapid growth in the demand for child care

sin city why is the divorce rate higher in urban areas divorce rates are higher in cities based on danish register data this paper shows that of the marriages formed in the city those couples who remain in the city have a 23 higher divorce rate than those who move out in this paper we test whether this observation is due to sorting of more stable marriages into rural areas or if there exists a causal effect of living in urban areas on marriage instability our identification strategy supplements the timing of events approach with an instrumental variable our findings suggest that the effect of living in an urban area on the divorce risks drops substantially and loses statistical significance once we address sorting keywords divorce search mobility city keywords j12 j64

would nonprofit workers accept to earn less evidence from france this article focuses on wage differentials between french nonprofit for profit and public sectors considering the public sector allows testing more extensively the labour donation theory preston 1989 the findings support this theory because nonprofit workers accept to earn significantly less than they would earn in the for profit and public sectors they also suggest differences in the motivations of workers in these sectors nonprofit workers are attracted to their work for reasons transcending material compensation

overeducation job mobility and earnings mobility among holders of first degrees abstractovereducation has been researched extensively for nearly three decades but some major issues in regard to it are still topics of ongoing debate by using a panel data that combines a survey of two cohorts of israeli first degree holders and data from administrative sources on jobs and wages we examine the contribution of job turnover cognitive abilities and continuing graduate studies to the likelihood of overeducation and wage dynamics the study produces four main findings first rapid job switching makes a negative contribution to the increase in employee s wage and there is a negative correlation between two variables an employee s tenure and the number of past employers in the years after the completion of degree studies and the probability of being overeducated second the contribution of the individual s cognitive abilities and quantitative reasoning skills to the likelihood of becoming overeducated is negative third the wages of overeducated employees are some 11 lower and ris

inflation and unemployment the world economy today is vastly different from the 1930s when seymour harris the chairman of this meeting infected me with his boundless enthusiasm for economics and his steadfast confidence in its capacity for good works economics is very different too both the science and its subject have changed and for the better since world war ii but there are some notable constants unemployment and inflation still preoccupy and perplex economists statesmen journalists housewives and everyone else the connection between them is the principal domestic economic burden of presidents and prime ministers and the major area of controversy and ignorance in macroeconomics i have chosen to review economic thought on this topic on this occasion partly because of its inevitable timeliness partly because of a personal interest reaching back to my first published work in 1941

a theoretical and empirical analysis of family migration and household production u s 1980 1985 migration studies have usually focussed on individual persons or workers there has however been some interest in family migration while single individuals in the labor market only have to worry about their own income families where both the husband and wife may be in the labor market need to be concerned with the income of both spouses hence double income families may be less likely to move than single income families jacob mincer 26 develops and explores this hypothesis to be called the tied mover hypothesis the tied mover hypothesis has recently been extended to include not only considerations of the wife s earnings but also considerations of her household production as factors in the family s migration decisions 38 in this paper the research on family migration will be extended in three ways a formal model of household production and family migration will be developed and used to generate testable hypotheses about family migration variables which otherwise would not have a clear economic interpretation are incorporated into the model the model will then be estimated and some policy implications will be discussed one policy implication concerns the efficiency of the labor market labor market efficiency needs to be judged not only in terms of the efficiency of the job search of single individuals but also in terms of the efficiency of the joint job search of double income families this paper is organized into five sections first a comparative static household production model of locational choice is developed 2 next this model of locational choice is used to develop a theoretical model of family migration third the data and empirical model are discussed fourth the empirical results are reported and interpreted in terms of three different types of migration estimates of the impact of selected variables on the distance of the move are also considered the final section summarizes the general findings and offers some policy implications

using trivariate copulas to model sample selection and treatment effects simultaneous nonlinear econometric models with discrete outcomes are often difficult to implement this article considers the use of the copula approach for a model with three jointly determined outcomes it also deals with the discrete case in which outcomes include a mixture of dichotomous choices and discrete count data we apply this technique to study self selection and interdependence between health insurance and health care demand among married couples the full model consists of a dichotomous choice equation for family insurance and a separate negative binomial equation for each spouse s health care use

in search of attention in agricultural commodity markets abstract this paper investigates the impact of attention driven behaviour on agricultural commodity prices we proxy attention driven behaviour using search queries for the commodity names in google we apply the ardl model to estimate the impact of search queries on three internationally traded agricultural commodities corn wheat and soybean using weakly data for the period 2009 2015 the results show that there is causal and permanent relationship between google search queries and prices of corn and wheat confirming the presence of the attention driven behaviour however the estimates do not confirm this relationship for soybean price

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

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

growth incentives to invest in a network externality environment firms that operate in the telecommunications industry often have to make large and risky investments in digital infrastructure this paper examines how firm size affects the incentive to invest in infrastructure projects in industry environments that incur substantial network externalities we suggest that in the presence of network externalities a firm s rate of growth first declines and then increases with the size of its user base an implication of this result is that firms may benefit from making investments in emerging digital infrastructure early enough to achieve a substantial user base and to gain that user base before other firms investments pre empt them the results mean that firms that undertake earlier successful investment may achieve preemption very quickly the sources of network externalities contribute to the incidence of strategic alliances in network industries particularly when coupled with the pressures of technical uncertainty copyright 1998 by oxford university press

does it pay to attend an elite private college cross cohort evidence on the effects of college type on earnings although a substantial and rising labor market premium is associated with college attendance in general little is known about how this premium varies across institutions of different types and across time in this paper we explicitly model high school students choice of college type characterized by selectivity and control based on individual and family characteristics including ability and parental economic status and an estimate of the net costs of attendance we estimate selectivity corrected outcome equations using data from both the national longitudinal study of the high school class of 1972 and high school and beyond which permit us to determine the effects of college quality on wages and earnings and how this effect varies across time even after controlling for selection effects strong evidence emerges of a significant economic return to attending an elite private institution and some evidence suggests this premium has increased over time

a comparison of choice based multinomial and nested logit models the family structure and welfare use decisions of divorced or separated women home based work differs from other employment because the work site is the home itself this difference means that the fixed costs of working at home are less than the fixed costs of working on site and that home based workers may engage in joint market

fisher phillips friedman and the measured impact of inflation on interest a reply the purpose of this paper is to demonstrate that empirical findings which persistently appear to contradict the fisher hypothesis that the nominal rate of interest should rise by the full amount of an increase in anticipated inflation are due basically to a failure to control for changes in the real rate of interest that are associated with changes in anticipated inflation we are guided in our search for proper specification of a fisher equation by a simple general equilibrium model which is employed to derive the impact of a change in anticipated inflation upon nominal interest given the requirement that commodity money and labor markets remain in equilibrium in effect we depart from the empirical tradition which has grown up around testing of the fisher hypothesis that takes the real interest rate to be independent of anticipated inflation and argues that for anticipated inflation properly measured the data ought to support the fisher hypothesis 1

the structure of indigenous food crop markets in sub saharan africa the rice market in uganda abstractusing data obtained from a series of nation wide market surveys in uganda this article attempts to document and assess the domestic rice market at all stages in the post harvest marketing chain from the farm gate to metropolitan area retail outlets the criteria used are quantities marketed prices marketing margins marketing costs and net returns to traders the results show that the regional rice markets are integrated into the national market and that on average little surplus is left for rice traders at all market stages if marketing costs are accounted for the spontaneously developed indigenous crop market works reasonably well

power couples changes in the locational choice of the college educated 1940 1990 college educated couples are increasingly located in large metropolitan areas these areas were home to 32 percent of all college educated couples in 1940 39 percent in 1970 and 50 percent in 1990 we investigate whether this trend can be explained by increasing urbanization of the college educated or the growth of dual career households and the resulting severity of the colocation problem we argue that the latter explanation is the primary one smaller cities may therefore experience reduced inflows of human capital relative to the past and thus become poorer

gender differentials in the payoff to schooling in rural china this article examines the gender differential in the payoff to schooling in rural china the analyses are based on a framework provided by the over education required education under education literature and the decomposition developed by chiswick and miller 2008 it shows that the payoff to correctly matched education in rural china is much higher for females than for males associated with this the wage penalty where workers are under qualified in their occupation is greater for females than for males over educated females however are advantaged compared with their male counterparts these findings are interpreted using the explanations offered for the gender differential in the payoff to schooling in the growing literature on earnings determination in china

a model of female labour supply in which supply is dependent upon the chances of finding a job in this paper we extend a model of female labour supply by considering the impact of the local labour market thus in our model a woman supplies her labour if she has both made the decision to participate and found a job this extension is of particular importance in times of high unemployment when discouraged worker effects will be at their strongest we also consider the contribution of such a model to the debate concerning the labour supply of women married to men who are unemployed

family proximity childcare and women s labor force attachment we show that close geographical proximity to mothers or mothers in law has a substantial positive effect on the labor supply of married women with young children we argue that the mechanism through which proximity increases labor supply is the availability of childcare we interpret availability broadly enough to include not only regular scheduled childcare during work hours but also an insurance aspect of proximity e g a mother or mother in law who can to provide irregular or unanticipated childcare using two large datasets the national survey of families and households and the public use files of the u s census we find that the predicted probability of employment and labor force participation is 4 10 percentage points higher for married women with young children living in close proximity to their mothers or their mothers in law compared with those living further away

double penalty in returns to education informality and educational mismatch in the colombian labour market abstractthis article examines the returns to education taking into consideration the existence of educational mismatches in the formal and informal employment of a developing country results show that the returns of surplus required and deficit years of schooling are different in the two sectors moreover they suggest that these returns vary along the wage distribution and that the pattern of variation differs for formal and informal workers in particular informal workers face not only lower returns to their education but suffer a second penalty associated with educational mismatches that puts them at a greater disadvantage compare to their formal counterparts

waiting for mr right rising inequality and declining marriage rates abstract this paper demonstrates that women search longer for their first or second husband in cities with higher male wage inequality and examines several alternative explanations a causal link is established by controlling for city fixed effects and city specific time trends and by using inequality in the woman s state of birth as a proxy for local male inequality increasing inequality explains about 25 of the marriage rate decline over the last few decades and this is not due to the endogenous moving or labor force decisions of women nor to the marital decisions of men in reaction to changes in their own wages

overqualification permanent or transitory this article analyses job mismatches in switzerland based on a subjective measure of overqualification according to job search and job matching theories overqualification is a transitory problem other theories show that overqualification can also be of a permanent nature we test the perpetuity of overeducation using panel data from the first eight waves of the swiss household panel shp covering the period 1999 to 2006 our empirical analysis reveals little evidence for lasting rigidities that would cause permanent job mismatches rather spells of overqualification are relatively short about half of all individuals who were overqualified in a given year had an adequate job match 1 year later while a short duration of overqualification would be consistent with job search and job matching theories our observation that the probability of a job mismatch does not significantly decrease with experience is at odds with these theories our article provides an alternative explanation for this phenomenon

the effect of uncertain educational requirements on education and wages this paper examines the effects of uncertain educational requirements the level of education required to enter an occupation varies with a number of factors workers may be uncertain as to their specific job when selecting an occupation thus they are also uncertain as to how much education they will need we find that occupations with more uncertainty pay males compensating wages however females do not receive compensating wages we also find a negative relationship between uncertain educational requirements and completed schooling for both men and women

the taxation of drivers and the choice of car fuel type in this paper the choice of the car fuel type is studied in the dutch situation three types are important gasoline diesel and lpg with 80 of the cars using gasoline incentives for using diesel or lpg are provided by the tax system that implies higher fixed cost but lower variable cost for users of these fuel types we start by studying fuel type choice on the basis of a logit model and move on to estimate demand functions for kilometres driven for social purposes while correcting for the possible selectivity bias we find that diesel and lpg are in general regarded as inferior alternatives but that monetary incentives are sufficiently strong to overcome this hurdle for drivers with a large demand for kilometres we also find that there are significant effects of the lower variable cost for diesel and lpg drivers on their demand for kilometres the conclusions are confirmed by estimation of a structural model in which fuel type choice and demand for kilometres are consistently explained on the basis of one set of preferences and unobserved heterogeneity is taken into account

food price seasonality in africa measurement and extent everyone knows about seasonality but what exactly do we know this study systematically measures seasonal price gaps at 193 markets for 13 food commodities in seven african countries it shows that the commonly used dummy variable or moving average deviation methods to estimate the seasonal gap can yield substantial upward bias this can be partially circumvented using trigonometric and sawtooth models which are more parsimonious among staple crops seasonality is highest for maize 33 percent on average and lowest for rice 16 percent this is two and a half to three times larger than in the international reference markets seasonality varies substantially across market places but maize is the only crop in which there are important systematic country effects malawi where maize is the main staple emerges as exhibiting the most acute seasonal differences reaching the sustainable development goal of zero hunger requires renewed policy attention to seasonality in food prices and consumption

regional trade government policy and food security recent evidence from zambia given heavy dependence on rainfed maize production countries in east and southern africa must routinely cope with pronounced production and consumption volatility in their primary food staple typical policy responses include increased food aid flows government commercial imports and stock releases and tight controls on private sector trade this paper examines recent evidence from zambia using a simple economic model to assess the likely impact of maize production shocks on the domestic maize price and on staple food consumption under alternative policy regimes in addition to an array of public policy instruments the analysis evaluates the impact of two key private sector responses in moderating food consumption volatility private cross border maize trade and consumer substitution of an alternate food staple cassava for maize the analysis suggests that given a favorable policy environment private imports and increased cassava consumption together could fill roughly two thirds of the maize consumption shortfall facing vulnerable households during drought years

food price volatility in sub saharan africa has it really increased the food price crisis of 2007 2008 and recent resurgence of food prices have focused increasing attention on the causes and consequences of food price volatility in international food markets and the developing world particularly in sub saharan africa in this paper we examine the patterns and trends in food price volatility using an unusually rich database of african staple food prices we find that international grain prices have become more volatile in recent years 2007 2010 but no evidence that food price volatility has increased in the region this contrasts with the widespread view that food prices have become more volatile in the region since the global food crisis of 2007 2008 in addition the results suggest that price volatility is lower for processed and tradable food than for nontradable food that volatility is lower in the major cities than in secondary cities and that maize price volatility is actually higher in countries with the most active intervention to stabilize maize prices these findings suggest that greater attention should be given to the high level of food prices in the region rather than volatility per se that regional and international trade can play a useful role in reducing food price volatility and that traditional food price stabilization efforts may be counterproductive

canadian contributions to family economics canadian scholars have made substantial contributions to the relatively new field of family economics these include new models of how men and women match in marriage markets and of how decisions are made in multi person households several were early contributors to the literature on married women s labour supply and labour supply in a family context and helped to develop empirical methods in this area a particular focus has been on the impacts of policy relevant parameters such childcare costs on family labour supply and child well being new work on child development the impact of early life conditions and the processes of intergenerational transmission also highlight the importance of family context in determining economic well being

overeducation in the labour market abstract this paper presents a review of the literature on overeducation the paper assesses the consistency of overeducation within the context of a number of theoretical frameworks including human capital theory hct and assignment theory the analysis goes on to discuss the various measurement controversies associated with the study of overeducation in order to provide an assessment of the extent to which the impacts of the phenomenon represent an economic reality as opposed to a statistical artefact after reviewing the literature it is concluded that the impacts of overeducation are likely to be non trivial and that the phenomenon may potentially be costly to individuals and firms as well as the economy more generally the existence of overeducation also raises some doubts with respect to the validity of some of the central assumptions and predictions of hct that are unlikely to be fully explained by gaps in the standard wage equation framework

what makes a new business start up successful this paper seeks a good measure of new business performance and then explains this measure by various dimensions of business strategy three criteria are used to create a one dimensional ordinal ranking of high medium and low performance for new business starts employment growth return on capital employed and labour productivity it is shown that statistical cluster analysis provides a convincing separation of a sample of new business starts into high medium and low performance categories using a minimum distance criterion for clustering an ordinal logit model with selection is then used to explain this performance ranking the results indicate that many widely discussed features of small business strategy have little or even negative impact on performance of the numerous aims that owner managers may adopt survival growth etc only one appears to have a major impact on performance the pursuit of the highest rate of return on investment many entrepreneurial perceptions of their own capabilities appear false or unimportant with the exception of organisational features and systems

marriage and the city search frictions and sorting of singles this paper develops and tests a model where cities play an important role as marriage markets the idea is simple cities are dense areas where singles can meet more potential partners than in rural areas to enjoy those benefits they are willing to pay a premium in terms of higher housing prices once married the benefits from meeting more potential partners vanish and married couples move out of the city attractive singles benefit most from a dense market and are therefore more likely to move to the city those predictions are tested and confirmed with a unique danish data set

multistage selection and the financing of new ventures using a random sample of 221 new swedish ventures initiated in 1998 we examine why some new ventures are more likely than others to successfully be awarded capital from external sources we examine venture financing as a staged selection process in which two sequential selection events systematically winnow the population of ventures and influence which ventures receive financing for a venture to receive external financing its founders must first select it as a candidate for external funding and then a financier must fund it we find evidence that founders select ventures as candidates for external finance based on their perceptions of market competition market growth and employment growth while financiers base funding decisions on objective verifiable indicators of venture development such as the completion of organizing activities marketing activities and the level of sales of the venture our findings have implications for venture financing and evolutionary theories of social processes

grain price and volatility transmission from international to domestic markets in developing countries summary understanding the sources of domestic food price volatility in developing countries and the extent to which it is transmitted from international to domestic markets is critical to help design better global regional and domestic policies to cope with excessive food price volatility and to protect the most vulnerable groups this paper examines short term price and volatility transmission from major grain commodities to 41 domestic food products across 27 countries in africa latin america and south asia we follow a multivariate garch approach to model the dynamics of monthly price return volatility in international and domestic markets the period of analysis is 2000 through 2013 in terms of price transmission we only observe significant interactions from international to domestic markets in few cases to calculate volatility spillovers we simulate a shock equivalent to a 1 increase in the conditional volatility of price returns in the international market and evaluate its effect on the conditional volatility of price returns in the domestic market the transmission of volatility is statistically significant in just one quarter of the maize markets tested more than half of rice markets tested and all wheat markets tested volatility transmission seems to be more common when trade imports or exports are large relatively to domestic requirements

overeducation undereducation and the british labour market this paper addresses the issue of overeducation and undereducation using for the first time a british dataset which contains explicit information on the level of required education to enter a job across the generality of occupations three key issues within the overeducation literature are addressed first what determines the existence of over and undereducation and to what extent are over and undereducation substitutes for experience tenure and training second to what extent are over and undereducation temporary or permanent phenomena third what are the returns to over and undereducation and do certain stylized facts discovered for the us and a number of european countries hold for britain

estimating social effects in matching markets externalities in spousal search this paper investigates the hypothesis that individuals are less willing to marry when there are more potential partners to search amongst and thus when others are also less prone to marry to do this it develops a reduced form method a variation on manski s 1993 model that allows identification of such spillovers in two sided matching markets estimates from this method are internally consistent unbiased robust to different definitions of the marriage market and large enough to warrant attention additional evidence suggests that the effect works via the proposed search mechanism

personal networks and nonagricultural employment the case of a farming village in the philippines abstract this article based on an intensive village survey in the philippines analyzes the effects of personal networks on rural villagers access to nonagricultural occupations and the terms of employment given to them a key finding is that personal networks are selectively used to reduce transaction costs and their impacts on employment conditions vary by size and by location of enterprises we find that when villagers are employed in unskilled work at small enterprises those who use family relative networks receive wage premiums however if we limit our sample to small enterprises located near our study village the family relative network premiums become insignificant presumably because of the overriding influence of the community wide network within a narrow local community contrary to the case of small enterprises unskilled workers wages at large enterprises are not much affected by personal networks but are largely determined by years of schooling and work experience the recent developmen

health plan choice and the utilization of health care services the effect of health plan membership on the utilization of health care services is of interest to both consumers and policymakers often estimation of that effect is difficult because data are nonexperimental and the dependent variable exhibits a high proportion of zeros the authors propose a model of utilization that addresses both problems after controlling for chronic illness and other observed variables they find no evidence of further selectivity bias in equations for physician contacts and inpatient days the authors estimates of the effect of health plan membership on utilization of services are similar to those from experimental data coauthors are roger feldman steven cassou and michael finch copyright 1991 by mit press

is there a genuine under utilization of skills amongst the over qualified two theories of over qualification are considered namely mismatch whereby workers do not find the most appropriate jobs for their skills because of imperfect information or labour market rigidities and heterogeneous workers whereby individuals with the same qualifications have different actual skill levels so that they can be over qualified in terms of formal qualifications while their skills are actually appropriate for the jobs that they do the evidence suggests that both theories are relevant in certain situations

trading off volatility and distortions food policy during price spikes this paper analyses the trade off between price distortions and reduced volatility when governments intervened in agricultural and food markets during the recent food price spikes we develop a model to derive how much distortions a government would introduce when it cares about price stability in a situation with limited policy options we show that there is a trade off and identify the optimal combination of distortions and stability for given international price shocks and interest groups preferences for stability we compare these theoretical findings with empirical indicators on actual government interventions in staple food markets we find that several countries have been able to reduce short run price volatility in the domestic markets while at the same time allowing structural medium and long term price changes to pass through to producers and consumers however this is not the general case for many countries even when explicitly taking into account the trade off and the benefits of reducing volatility government policies appear far removed from the optimal trade off and there appears to be much room for policy improvement

local amenities and life cycle migration do people move for jobs or fun abstract do households move for jobs or fun and where do they go when they move we address these questions using the 1970 2000 us census based on a panel of quality of life and business environment measures households prefer msas in warm coastal areas and non metropolitan locations while firms prefer large growing cities in addition cities with improving business environments acquire increasing shares of workers especially workers with high levels of human capital cities with improving consumer amenities become relatively more populated by retirees further analysis of individual level migration decisions indicates that regardless of marital status young highly educated households tend to move towards places with higher quality business environments this tendency is especially pronounced among highly educated couples who are more subject to job market co location problems in contrast regardless of education couples near retirement tend to move away from places with favorable business environments and towards places with highly valued consumer amenities these patterns help explain why areas unattractive to both households and business have struggled as with upstate new york while the sun belt and other regions are thriving
