Overeducation, wages and promotions within the firm

We analyse data from personnel records of a large firm producing energy and telecommunication and test for the effect of deviations between required and attained education of workers. Required education is measured as hiring standards set by the firm. We find the usual effects of over- and undereducation in a wage regression, thus rejecting the argument that such effects are exclusively due to firm fixed effects. Distinguishing, within the firm, between a sheltered internal labour market and an exposed external labour market, we find that at the internal labour market over- and undereducation significantly affect career development, in particular at younger ages, but that such effects are mostly absent at the firm's external labour market.     

Investments in education and welfare in a two-sector,random matching economy

We consider a random matching model where heterogeneous agents choose optimally to invest time and real resources in education. Generically, there is a steady state equilibrium where some agents, but not all of them, invest. Regular steady state equilibria are constrained inefficient in a strong sense. The Hosios (1990) condition is neither necessary nor sufficient for constrained efficiency. We also provide restrictions on the fundamentals sufficient to guarantee that equilibria are characterized by overeducation (or undereducation), present some results on their comparative statics properties, and discuss the nature of welfare improving policies.     

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.     

SKILLS MISMATCH: CONCEPTS,MEASUREMENT AND POLICY APPROACHES

The term skills mismatch is very broad and can relate to many forms of labour market friction, including vertical mismatch, skill gaps, skill shortages, field of study (horizontal) mismatch and skill obsolescence. In this paper, we provide a clear overview of each concept and discuss the measurement and inter‐relatedness of different forms of mismatch. We present a comprehensive analysis of the current position of the literature on skills mismatch and highlight areas which are relatively underdeveloped and may warrant further research. Using data from the European Skills and Jobs Survey, we assess the incidence of various combinations of skills mismatch across the EU. Finally, we review the European Commission's country‐specific recommendations and find that skills mismatch, when referring to underutilized human capital in the form of overeducation and skills underutilization, receives little policy attention. In cases where skills mismatch forms part of policy recommendations, the policy advice is either vague or addresses the areas of mismatch for which there is the least available evidence.     

Educational mismatch,wages, and wage growth: Overeducation in Sweden, 1974–2000

We examine the impact of educational mismatch on wages and wage growth in Sweden. The empirical analyses, based on cross-sectional and panel data from the Level of living surveys 1974–2000, are guided by two main hypotheses: (a) that educational mismatch reflects human capital compensation rather than real mismatch, and (b) that educational mismatch is real but dissolves with time spent in the labour market, so that its impact on wages tends toward zero over a typical worker's career. Our findings do not support these hypotheses. First, significant differences in contemporaneous economic returns to education across match categories remain even after variations in ability are taken into account. Second, we find no evidence that the rate of wage growth is higher among overeducated workers than others. Our conclusion is that the overeducated are penalized early on by an inferior rate of return to schooling from which they do not recover.     

Non-linear and non-symmetric exchange-rate adjustment: Evidence from medium- and high-inflation countries

This paper analyses a model of non-linear exchange rate adjustment that extends the literature by allowing asymmetric responses to over- and under-valuations. Applying the model to Greece and Turkey, we find that adjustment is asymmetric and that exchange rates depend on the sign as well as the magnitude of deviations, being more responsive to over-valuations than undervaluations. Our findings support and extend the argument that non-linear models of exchange rate adjustment can help to overcome anomalies in exchange rate behaviour. They also suggest that exchange rate adjustment is non-linear in economies where fundamentals models work well.

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.     

Aggregate Versus Disaggregate Data in Measuring School Quality

This article develops a measure of efficiency to use with aggregated data. Unlike the most commonly used efficiency measures, our estimator adjusts for the heteroskedasticity created by aggregation. Our estimator is compared to estimators currently used to measure school efficiency. Theoretical results are supported by a Monte Carlo experiment. Results show that for samples containing small schools (sample average may be about 100 students per school but sample includes several schools with about 30 or less students), the proposed aggregate data estimator performs better than the commonly used OLS and only slightly worse than the multilevel estimator. Thus, when school officials are unable to gather multilevel or disaggregate data, the aggregate data estimator proposed here should be used. When disaggregate data are available, standardizing the value-added estimator should be used when ranking schools.     

Can the theory of planned behaviour explain walking to and from school among Australian children? A social marketing formative research study

Evidence indicates that lower levels of obesity among school‐age children can be achieved through active travel to school. This research aimed to investigate the explanatory potential of constructs in the theory of planned behaviour for carers' decisions about their children's walking to and from school. The data from two online surveys of 1,076 carers in 2 Australian states showed that the theory of planned behaviour explained 35.7% of the variance in walking to and from school. The results indicate that higher perceived behavioural control, social norms, and intentions among carers are associated with higher incidence of walking to and from school by children in Australia. Limitations of the current study and future research directions are outlined.     

The expected real return to equity

The expected return to equity – typically measured as a historical average – is a key variable in the decision making of investors. A recent literature uses analysts' forecasts, investor surveys or present-value relationships and finds estimates of expected returns that are sometimes much lower than historical averages. This study extends the present-value approach to a dynamic optimizing framework. Given a model that captures this relationship, one can use data on dividends, earnings and valuations to infer the model-implied expected return. Using this method, the estimated expected real return to equity ranges from 4.9% to 5.6% . Furthermore, the analysis indicates that expected returns have declined by about 3 percentage points over the past 40 years. These results indicate that future returns to equity may be lower than past realized returns.     

Born on the wrong day? School entry age and juvenile crime

Kindergarten entry age is known to impact schooling outcomes. Less is known, however, about the role of school starting age on economic outcomes outside of the classroom. In this paper we use administrative data from Louisiana to analyze the effect of school starting age on juvenile crime. We find that late school entry by one year reduces the incidence of juvenile crime for young black females, particularly in high crime areas. The mediating effects of late school entry for this subgroup appear to be driven by reductions in non-felony offenses. We propose age related differences in human capital accumulation as a potential explanation for our findings.

Balancing family and work: The effect of cash benefits for working mothers

The aim of this paper is to measure the potential effect of a family policy introduced in Spain in 2003 that provides working mothers with a monthly cash benefit of 100 euros per child aged under 3 years. We explore the effect of the policy on eligible women's labour market participation. In the tradition of the policy evaluation literature we use a difference-in-differences-in-differences (DDD) estimation approach. Our results support a small but significant positive effect of the policy. We find that since the implementation of the policy the labour market participation rate for mothers of children aged under 3 has risen by 3 percentage points compared to the rate for non-policy-eligible females. This represents 5% of their average labour market participation in 2002, the year before the policy was implemented. This overall policy effect is dominated by the effect of the policy among high school educated females.

A Two‐Step Procedure to Measure Representativeness of Internet Data Sources

So far, statistics has mainly relied on information collected from censuses and sample surveys, which are used to produce statistics about selected characteristics of the population. However, because of cost cuts and increasing non‐response in sample surveys, statisticians have started to search for new sources of information, such as registers, Internet data sources (IDSs, i.e. web portals) or big data. Administrative sources are already used for purposes of official statistics, while the suitability of the latter two sources is currently being discussed in the literature. Unfortunately, only a few papers devoted to statistical theory point out methodological problems related to the use of IDSs, particularly in the context of survey methodology. The unknown generation mechanism and the complexity of such data are often neglected in view of their size. Hence, before IDSs can be used for statistical purposes, especially for official statistics, they need to be assessed in terms of such fundamental issues as representativeness, non‐sampling errors or bias. The paper attempts to fill the first gap by proposing a two‐step procedure to measure representativeness of IDSs. The procedure will be exemplified using data about the secondary real estate market in Poland.

School Quality and Real House Prices: Inter- and Intrametropolitan Effects

This study focuses on explaining variations in real constant-quality house prices in jurisdictions located in multiple MSAs. Using a hedonic house price framework, we test competing theories of house price determination. Using two variants of the random coefficients model, we find that public school quality has a very large impact on real constant-quality house prices. Our results suggest that capitalization of school quality differences occurs on a per lot basis rather than per square foot of land. Also important to the explanation of variations in house prices are variables derived from urban theory, such as distance to the CBD, and from the amenity literature, such as a community's crime rate, arts, and recreational opportunities

Compound weighted Poisson distributions

In this paper, we discuss discrete compound distributions, in which the counting distribution is a weighted Poisson distribution. The over- and under-dispersion of these distributions are then discussed by analyzing the Fisher index of dispersion as well as a newly introduced factorial moment to mean measure. Several cases of compounding distributions and weight functions are subsequently examined in detail.
