This article estimates a control function estimator with training effect modelled as a random coefficient, partitioned into an observed and unobserved component. The article analyzes the earnings effect of participating in labor market training programs for three cohorts during the 1980s and the beginning of the 1990s. It separates the analysis between Swedish and foreign‐born to identify differences in their responses to training. The results indicate that there is positive sorting in training: slightly positive effects for both groups but somewhat larger for the foreign‐born. Further, consistent with results from several previous studies, the article finds that being young often means no positive pay‐off from training, and the same is found for persons with only a primary education. In conflict with earlier studies, the article finds that males have a better pay‐off from training than females. Rewards from training are higher for foreign‐ than for native‐born and rewards among the former vary by place of birth and how long they have been in the country.

Internet use has become particularly prevalent among adolescents, prompting much thought and concern about both its potential benefits and adverse effects on adolescent learning outcomes. Much of the empirical literature on the impact of Internet use on adolescent learning outcomes is mixed, and few studies examine the causal relationship between the two in rural China. In order to bridge these gaps, we use empirical analysis to investigate the effect of Internet use on the learning outcomes of adolescents in rural China.

We use fixed effect models with samples drawn from a large nationally representative dataset (the China Family Panel Studies—CFPS) to identify the causal impacts of Internet use on the learning outcomes of three cohorts (Cohort A (N = 540), Cohort B (N = 287) and Cohort C (N = 827)) of adolescents in rural China.

The results of the descriptive analysis show a continued increase in the number of adolescents accessing the Internet and the amount of time they spend online. The results of the fixed effect models show that Internet use has positive (in many of the analyses), but mostly insignificant impacts, on the learning outcomes of adolescents. In the sets of results that find significant associations between Internet use and learning outcomes, the measured effects are moderate.

This study investigates the causal relationship between Internet use and adolescent learning outcomes in rural China. The findings claim that there is not a great need to worry about adverse effects of Internet use on adolescent learning development. Attention, however, should focus on seeking ways to improve the positive effects of the Internet use on adolescent learning outcomes. The study will provide a reference and experience for the development of education and the Internet in rural areas and promote the integrated development of urban and rural areas in China.

This paper aims to build on existing studies on the relationship between individual wages, age and experience, and provide new evidence on the determinants of wages in Italy.

Wage‐age profiles, which include cohort variables to capture generational differences in wages and are characterised by a changing‐over‐time structure, are estimated by fixed and random effects panel regressions. The analysis exploits a longitudinal dataset of administrative data on wages for the period 1985‐1999.

This paper shows that wage to age profiles for different cohorts of workers are not stable over time: although younger generations of Italian workers are benefiting from higher starting wages than older generations, they face the prospect of lower growth of future earnings. It also confirms the existence of a significant supply effect: the bigger the cohort relative to the active population, the smaller the cohort's gain in terms of wage levels. Finally, it captures the dependence of individual wages on aggregate labour market conditions: individual wages are shown to be negatively related to the unemployment rate and positively related to the union wage index.

Although the paper does not propose a novel theoretical approach to individual wage analysis, it demonstrates the benefits of a more integrated empirical analysis of individual wages.

The empirical findings suggest that it would be possible and useful to integrate the changing age profiles of individual wages with the estimation and projections of Italian aggregate industry and service sector average wages.

The paper provides new evidence on the determinants of the dynamics of individual wages through the estimation of time‐varying wage to age profiles of workers in the Italian industry and service sectors.

Means, medians and SD for available socio‐economic status (SES) black‐white differences are here substituted for those of IQ in a between‐groups model published by the author over a decade ago. The goodness of fit of the SES variables used is compared with that for the earlier IQ data. Even when SES variables are relatively successful this can be viewed as additional evidence of the importance of IQ differences to black‐white differences in delinquency.

This study, based on data from the National Survey of Families and Households, confirms normative preference for nuclear households across all cohorts and racial/ethnic groups throughout this century. However, a noteworthy minority (about 30%) did live with grandparents at some time during their childhood. Living with grandparents as well as having a grandparent live in one's parental household were somewhat more prevalent during the 30's and 40's, indicating that extended households may have been formed in response to the Depression and especially World War II. There also is a significant effect of nuclear family structure: living arrangements with grandparents predominate among those who did not live with both parents at some time during their childhood. The data also suggest that it is important to differentiate between grandparental living arrangements that are oriented toward the care of the grandchildren and those arrangements that imply care for the grandparent: the former arrangement predominates among Blacks, whereas the latter is more common among Whites. During the past decade there has been increased interest in extended family living arrangements and particularly in households including grandparents and/or grandchildren. This interest reflects several demographic trends during the latter part of this century, especially increases in divorce and in parental problems (drugs, AIDS) that preclude parents from taking care of their own children as well as increases in longevity and in the survival of frail elderly, many of whom come to live with their adult children. Census data offer information on the prevalence of extended family arrangements at any one point in time, but they are insufficient to estimate a person's lifetime “risk” of living with grandparents and provide only limited information on the duration of such living arrangements. Data from the National Survey of Families and Households (NSFH) include information not only on whether individuals ever lived with their grandparents but also on the type and the duration of such arrangements. Based on this data set, this article assesses trends in living arrangements with grandparents, and variations in these trends by race and childhood family structure.

The purpose of this paper is to examine cigarette consumption behavior of younger cohorts in the urban and rural areas of Iran. The authors use Iran’s annual Household Income and Expenditures Surveys (HIES) database over 2007–2013 for the statistical analysis. In order to control for a large number of households with zero expenditure on cigarette consumption, the authors have used the double-hurdle modeling approach for counting the outcomes of interest. The authors have also limited the sample to cases in which the head of household is between the ages of 21 and 45 and all children are younger than 18.

In this study, the authors have conducted a multivariate econometric analysis to identify the impact of age and birth year cohort on the demand for cigarettes among Iranian households. The authors have used the HIES data for multiple years in the analysis. The ideal data set for the analysis is a panel data that include information on cigarette consumption of various age cohorts over a long period of time. Since no suitable panel data are available, the authors have constructed a multi-year cohort data by extracting cohort data from the annual HIES data set. Due to the unique properties of cigarette consumption, the authors have used the double-hurdle econometric model with appropriate diagnostics.

After controlling for price and demographic factors, which affect the demand for cigarettes, the authors find that the younger cohorts in rural areas, who smoke, tend to consume fewer cigarettes than the older ones; however, the opposite is true among urban households. The probability of being a non-smoker is larger for younger cohorts in both rural and urban areas. Among smokers, the authors observe an inverse U-shape relation between age and quantity of cigarettes consumed per day. The trend is positive up to age 45, but diminishes for older smokers because of health concerns.

In comparison to previous studies of tobacco consumption in Iran, the authors have used a more comprehensive household income and expenditure survey data set with a large number of observations. Furthermore, the authors have applied an econometric method (the double-hurdle model), which is suitable for the analysis of the determinants of demand for cigarettes when a subset of households report no cigarette consumption.

The purpose of this paper is to estimate the impact of Internal Revenue Code cost recovery provisions – Section 179 and “bonus depreciation” – on farm capital investment.

The authors construct a synthetic panel of data consisting of cohorts of similar farms based on state and production specialization using the USDA’s Agricultural Resource Management Survey for years 1996-2012. Employing panel data methods, the authors are able to control for time-invariant fixed effects, as well as the effects of past investment on current investment.

The authors estimate statistically significant investment demand elasticities with respect to the Section 179 expensing deduction of between 0.28 and 0.50. A change in bonus depreciation, on average, had little impact on capital investment.

The estimates suggest there is a modest effect of the cost recovery provisions on investment overall, but a stronger effect on farms that have more than $10,000 in gross cash farm income. There are other implications for the agricultural sector: the provisions may encourage technology adoption with its associated benefits, such as reduced cost of production and improved conservation practices. On the other hand, the policy could contribute to the growing concentration in production as large commercial farms expand their operated acreage to take advantage of increasingly efficient physical capital.

To the authors’ knowledge, this is the first research to use a nationally representative dataset to estimate to impact of Section 179 and “bonus depreciation” on farm investment. The findings provide evidence of the provisions’ impact on farm capital purchases.

This study investigates how the consumption of sugar products and non-alcoholic beverages has changed across birth cohorts. In addition, this study examines how the socio-economic gaps in the consumption of said products have evolved across birth cohorts.

The research data are drawn from the Finnish household expenditure surveys covering the period 1985–2016 (n = 44,286). An age-period-cohort methodology is utilised through the age-period-cohort-trended lag model. The model assumes that the linear long-term component of change is caused by generations replacing one-another, and that the age effect is similar across cohorts.

Sugar products and non-alcoholic beverages occupied a larger portion of more recent birth cohorts' food baskets. Cohort differences were larger in beverage consumption. Lower income was associated with a higher food expenditure share of sugar products in several cohorts. A higher education level was linked to a higher food expenditure share of sugar products in more cohorts than a lower education level. In cohorts born before the 1950s, non-alcoholic beverages occupied a larger portion of the food baskets of the high socio-economic status groups. This gap reversed over time, leading to larger food expenditure shares of non-alcoholic beverages in low socio-economic status groups.

This study assessed how the consumption of sugar products and non-alcoholic beverages has changed across birth cohorts. In addition, this study assessed how socio-economic differences in the consumption of said products have changed. The results highlight that sugar products and non-alcoholic beverages occupy larger portions of more recent birth cohorts’ food baskets. The results also highlight a reversal of socioeconomic differences in non-alcoholic beverage consumption.

It has long been recognised that cohort and cross‐sectional age‐earnings profiles differ. A standard procedure, which is quite reasonable in the absence of more information, is to obtain a cohort profile by simply adding the general rate of growth of real earnings to the growth of earnings associated with age, as shown by cross‐sectional data. Indeed, this would seem to be supported by the observation that cross‐sectional earnings profiles for a number of different years show a great deal of stability in their general shape. The main question considered here is whether cohort profiles can in fact be estimated in this simple way. A basic statistical model of age‐earnings profiles is described in the next section. The model is then applied to several groups of professional scientists, chemists and physicists in Britain and Australia, in the third section. The data were obtained from special surveys of career histories and are described briefly in the Appendix. A feature of the surveys is that sufficient data were collected to enable separate analyses of male and female scientists to be carried out.

This study aims to examine preferences for both transformational and transactional leadership behavior for gender‐ and age‐based cohort differences. The purpose of this research is to enhance leadership and organizational change initiatives in Romania via the identification of age cohort and gender effects with respect to attitudes towards common leadership behaviors.

The research is conducted via a survey through the administration of questionnaires. The sample consists of 324 managers from commercial and service organizations in Romania, a country in which this issue has not previously been investigated.

The findings reveal that there are differences in preferences for leadership behavior based on age cohorts that reached maturity before or after the fall of Ceauşescu during the 1989 revolution. Also, female participants displayed a greater preference for transformational leadership behaviors relative to transactional leadership behaviors.

This is the first study to examine the effects of leadership preference based on age cohorts in Romania. The study also is one of the first to empirically examine the effects of age cohorts on leadership after the fall of communism in Eastern Europe. As such, these findings offer guidance in the development and implementation of leadership development initiatives and change management interventions for organizations operating in Romania, and present one example of cohort‐based and leadership‐specific attitude change in a country that is transitioning from communism to a free market system.
