can falling supply explain the rising return to college for younger men a cohort based analysis although the college high school wage gap for younger u s men has doubled over the past 30 years the gap for older men has remained nearly constant in the united kingdom and canada the college high school wage gap also increased for younger relative to older men using a model with imperfect substitution between similarly educated workers in different age groups we argue that these shifts reflect changes in the relative supply of highly educated workers across age groups the driving force behind these changes is the slowdown in the rate of growth of educational attainment that began with cohorts born in the early 1950s in all three countries

econometric analysis of cps type unemployment data analysts studying the unemployment experiences of population members often have access to data collected from a sample of individuals at a point in time which contain the length of the ongoing spell of unemployment for sample members currently unemployed no information regarding the lengths of ongoing employment spells is collected this paper considers how such information may be utilized in the estimation of parameters of alternating renewal process models of labor market attachment in the presence of both observed and unobserved population heterogeneity a number of models are presented and estimation is carried out using a cps type data set from italy

do online homework tools improve student results in principles of microeconomics courses recent technological advances in education have made it possible for instructors to use new tools in their attempt to enhance student interest and improve understanding of economic principles a substantial body of economic education literature has examined the effectiveness of these tools in influencing student performance generally these studies compare student performance between a control group and a test group in the last decade or so these new tools have tended to focus on different aspects of computer technology and whether or not use of the technology enhances student learning along these lines agarwal and day 1998 found that use of the internet in economics instruction had a positive effect on student learning as measured by improvement in the test of understanding in college economics tuce scores in both graduate and undergraduate economics courses similarly sosin et al 2004 suggest that tuce scores of students in classes using extensive technology showed a small but significant improvement over those students in classes using little technology this paper contributes to and extends the literature by reporting the results of an empirical study investigating the effect on student learning of an online homework tool aplia compared to the more traditional instructor assigned and graded homework do online homework tools improve student results in principles of microeconomics courses

immigration and inequality immigration is often viewed as a proximate cause of the rising wage gap between highand low skilled workers nevertheless there is controversy over the appropriate theoretical and empirical framework for measuring the presumed effect and over the precise magnitudes involved this paper offers an overview and synthesis of existing knowledge on the relationship between immigration and inequality focusing on evidence from cross city comparisons in the u s while some researchers have claimed that a cross city research design is inherently flawed i argue that the evidence from cross city comparisons is remarkably consistent with recent findings based on aggregate time series data in particular cross city and aggregate time series comparisons provide support for three key conclusions 1 workers with below high school education are perfect substitutes for those with a high school education 2 high school equivalent and college equivalent workers are imperfect substitutes with an elasticity of substitution on the order of 2 3 within education groups immigrants and natives are imperfect substitutes together these results imply that the average impacts of recent immigrant inflows on the relative wages of u s natives are small the effects on overall wage inequality including natives and immigrants are larger reflecting the concentration of immigrants in the tails of the skill distribution and higher residual inequality among immigrants than natives even so immigration accounts for a small share 5 of the increase in u s wage inequality between 1980 and 2000

efficiency in the use of technology in economic education some preliminary results this paper reports preliminary results of a project funded by the andrew f mellon foundation that is intended to ascertain whether technology enhanced introductory economics courses are more effective and also more efficient than traditionally taught courses blecha s 2000 survey of faculty at different types of institutions of higher education documents that economics instructors now use a continuum of technological enhancements ranging from e mail web sites presentation software computerized games and spreadsheets to computerized instruction and distance learning while several studies investigate the consequences of using technology on student performance there has been little attempt to compare the efficacy and efficiency of the various types of available technologies

female participation and labor market attachment in rural canada this article explores the reasons for differences in female rural urban participation rates by estimating a dynamic model of participation allowing for unobserved heterogeneity and state dependence using canadian panel data the results suggest that overall observed differences in rural urban participation rates are primarily due to differences in observed socioeconomic characteristics however for women resident in low income households there is evidence that the operation of rural labor markets effectively lowers their participation rates copyright 2002 oxford university press

the lake wobegon effect in student self reported data for over a decade garrison keillor assured listeners of american public radio s a prairie home companion that in lake wobegon all the women are strong all the men are good looking and all the children are above average judith yaross lee 1991 although we can offer no explanation for the women s strength and men s appearance we may be able to shed light on the reports of exceptional achievement of lake wobegon s children our research indicates that students tend to overstate their academic accomplishments and that belowaverage students are less likely to report their achievements at all this produces a lake wobegon effect in student selfreported data overstated achievement may produce biased estimates of the relationship between achievement and educational inputs if overstatement is correlated with achievement in economic education the use of student self reported data for empirical analysis is not uncommon both the national assessment of economic education data base and the third edition of the test of understanding in college economic data base use some self reported data in addition some economic education researchers develop their own data sets that include student self reported data systematic reporting biases in data collection also create problems for empirical analysis nonrandom reporting has been documented as a potential problem in economic education students are more likely to report grading errors on examinations when the correction of these errors results in raising their grades dale 0 cloninger and robert hodgin 1986 sample selection bias resulting from using an unrepresentative sample has been shown to result from data lost between pretests and posttests william e becker and william b walstad 1990 students failure to take standardized tests claude montmarquette and rachel houle 1986 and selection procedures used to place students in experimental and control groups john j siegfried and george h sweeney 1980

short term employment transitions of the canadian labour force rural urban differences in underemployment using data from the canadian survey of labour and income dynamics slid for the period 1993 1996 we examine patterns and determinants of labour force transitions of adequately employed and underemployed workers in an attempt to explore whether employment dynamics significantly differ between rural and urban workers so as to disadvantage rural economic performance the results indicate that rural adequately employed workers are significantly more likely to enter underemployment but once they are underemployed they also have a higher probability of re entering adequate employment further we also found weak evidence that the education level of workers has a lower impact on the probability of moving out of underemployment in rural than in urban areas in addition rural women are significantly less likely than their male counterparts and urban workers to enter adequate employment although the presence of young children does not seem to especially constrain the employment of rural women the results suggest that labour force transition in and out of adequate employment and particularly underemployment significantly differ between rural and urban workers and should be taken into account when evaluating employment hardship in rural canada

the impact of immigration on the structure of wages theory and evidence from britain immigration to the uk particularly among more educated workers has risen appreciably over the past 30 years and as such has raised labor supply however studies of the impact of immigration have failed to find any significant effect on the wages of native born workers in the uk this is potentially puzzling since there is evidence that changes in the supply of educated natives have had significant effects on their wages using a pooled time series of british cross sectional micro data on male wages and employment from the mid 1970s to the mid 2000s this paper offers one possible resolution to this puzzle namely that in the uk natives and foreign born workers are imperfect substitutes we show that immigration has primarily reduced the wages of immigrants and in particular of university educated immigrants with little discernable effect on the wages of the native born

the effect of gender and race on student performance in principles of economics the importance of personality type do women and minorities perform more poorly in economics courses than their white male counterparts there are a number of studies that indicate that they do siegfried 1979 ferber et al 1983 lumsden and scott 1987 gohmann and specter 1989 watts and lynch 1989 anderson et al 1994 in addition there are some studies that indicate that students personality types adversely affect their performance in economics courses as well borg and shapiro 1996 zeigert 2000 however no one has yet studied how a student s personality type combines with race and gender to affect performance in economics courses to explore this issue this study tests for the statistical significance of a number of interaction effects between race and gender and the kiersey bates temperament types in an ordered probit model explaining a student s grade in principles of macroeconomics it is concluded that race and gender do matter in a student s performance in principles of macroeconomics but not in a simple direc

analyzing the length of welfare spells abstract this paper studies the determinants of the length of individual spells of welfare focusing on how the length of a spell affects the probability of its termination the analysis utilizes six years of monthly data on time spent in the afdc program among female household heads a variety of duration dependence models are estimated monthly afdc participation does not show strong evidence of duration dependence two distinct groups appear to utilize welfare one with a very low and constant probability of leaving welfare and a second group which is more affected by time on the program

panel estimates of the canadian rural urban women s wage gap this article analyzes the female rural urban wage gap in canada using longitudinal data from the survey of labour and income dynamics 1993 96 we estimate a two step wage equation accounting for unobserved heterogeneity and sample selection the results indicate that a statistically and economically significant rural urban wage gap remains after controlling for observed and unobserved characteristics further the results suggest this rural urban wage difference is not simply induced by immobility between rural and urban markets rather consistent with the effect of thinner rural labor markets the evidence indicates that rural urban differences in the impact of a number of explanatory variables are significant

rural urban welfare program and labor force participation nonmetro poor in the midwest participate more in the labor force and less in welfare programs than metro poor we formalize how household composition capital labor market conditions and state specific regulations define opportunity sets then estimate a bivariate binomial probit model of work and program participation choices an oaxaca decomposition analysis is conducted to compare differences in characteristics to differences in behavior in explaining the two groups choices we find no behavioral basis for the difference in labor market participation and while most of the lower midwestern nonmetro welfare program participation is due to demographics some is due to different life cycle behavior

can web courses replace the classroom in principles of microeconomics the proliferation of economics courses offered partly or completely online arnold katz and william e becker 1999 raises important questions about the effects of the new technologies on student learning do students enrolled in online courses learn more or less than students taught face to face can we identify any student characteristics such as gender race act scores or grade averages that are associated with better outcomes in one technology or another how would the online or face to face students fare if they had taken the course using the alternative technology this paper addresses these questions using student data from our principles of microeconomics courses at michigan state university

immigration and wages evidence from construction to identify relative wage impacts of immigration we make use of certification and licensing requirements in the norwegian construction sector that give rise to exogenous variation in immigrant employment shares across trades individual panel data reveal substantially lower wage growth for workers in trades with rising immigrant employment than for other workers selective attrition from the sector masks the causal wage impact unless accounted for by individual fixed effects for low and semi skilled workers effects of new immigration are comparable for natives and older immigrant cohorts consistent with perfect substitutability between native and immigrant labor within trade finally we present evidence that immigration reduces price inflation as price increases over the sample period were significantly lower in activities with growth in the immigrant share than in activities with no or small change in immigrant employment

migration and imperfect labor markets theory and cross country evidence from denmark germany and the uk we investigate the labor market effects of immigration in denmark germany and the uk three countries which are characterized by considerable differences in labor market institutions and welfare states institutions such as collective bargaining minimum wages employment protection and unemployment benefits affect the way in which wages respond to labor supply shocks and hence the labor market effects of immigration we employ a wage setting approach which assumes that wages decline with the unemployment rate albeit imperfectly we find that the wage and employment effects of immigration depend on wage flexibility and the composition of the labor supply shock in germany immigration involves only moderate wage but large unemployment effects since immigrants are concentrated in labor market segments with low wage flexibility the reverse is true for the uk and denmark

urban effects on participation and wages are there gender differences abstract this paper estimates participation and wage equations using panel data from the united kingdom to explore gender differences in urban wage and participation premiums the results suggest a small but economically significant urban participation premium for women but none for men results from the wage estimations suggest that after controlling for sample selectivity observed and unobserved heterogeneity the urban premium is larger for women this wage premium is also larger for married or cohabiting women relative to others there is also evidence of higher urban returns to experience for men and lower urban wage depreciation for both men and women

the duration of welfare spells probability distributions for the duration of welfare spells are estimated the principle guiding the work is that a recipient will not exit from welfare if the expected utility on welfare exceeds the expected utility of welfare the analysis indicates that while the majority of welfare spells are of short duration a nontrivial minority of spells are quite long those recipients with long spells are found to differ in predictable ways from those experiencing brief spells this suggests that strategies to move women off welfare are unnecessary in many cases and should be targeted on those most likely to be long term recipients copyright 1987 by mit press

immigrant native wage gaps in time series complementarities or composition effects previous research has shown that immigrants wages decrease when the supply of immigrants increases this negative correlation has been interpreted as evidence of immigrant native complementarities in production the present study finds that it is instead due to changing immigrant composition

research in economic education five new initiatives research is essential for improvement in teaching and learning economics william e becker et al 1991 called for new research on the relative merits of multiple choice and essay tests on the lasting effects of course work in economics and on the effects of instructors instructional techniques and new technologies on student learning to respond to the call the committee on economic education cee of the american economic association recruited robin bartlett william becker w lee hansen peter kennedy and the authors to organize a conference that would jump start new research projects the organizers chose three conference goals identifying research priorities recruiting new economists to economic education research and building teams to undertake identified priorities they recruited 21 economists to participate 1 provided them with a list of potential research questions and asked them which questions were most important and which they were willing to work on with survey results in hand the organizers divided participants into five teams corresponding to the following five topics teaching methods and incentives for collegelevel economics instruction ph d education in economics in the united states improving the assessment of student learning in college economics courses long term effects of learning economics and efficiency in the use of technology in economic education at the conference participants discussed briefing papers prepared for each topic worked on project design and funding issues and began writing proposals herein we describe our research priorities and our progress in developing research plans and securing financial support
