A Panel Data Analysis of the Incidence and Impact of Over-education

This paper adds to the overeducation literature using panel data from the British Household Panel Survey. Much has been written about who is more likely to be overeducated, and the impact of being overeducated on wages, at particular points in time using cross-sectional data. Panel data allows us to control for unobserved individual heterogeneity in the determinants of incidence and impact of overeducation. The paper goes on to estimate the determinants of transitions out of overeducation, providing new information about its duration, and the factors that influence being in, and escaping from, this state

Labour market job matching for UK minority ethnic groups

Estimates of over education from different ethnic groups are presented using a new method of calculating over education and data from the UK Labour Force Survey. Calibrated against existing mean methods, the new approach leads to lower levels of over education for men and women. While the overall extent of over education has similarities with earlier studies, the differences between ethnic groups are far less than those found in some studies and fall even further when we control for other productivity related differences. Gender differences can be partially explained by differences in working part-time, whereas some ethnic differences are exacerbated slightly by being temporarily over educated, as well as by differences in the subject of degree

Is the Over-Education Wage Penalty Permanent?

Much has been written about the impact of over-education on wages using cross-sectional data, although there have been few studies that analyse the returns to over-education in a dynamic setting. This paper adds to the existing literature by using panel data to investigate the impact and permanence of over-education wage penalties, whilst controlling for unobserved individual heterogeneity. Our fixed effects estimates suggest that the over-education wage penalty cannot solely be explained by unobserved heterogeneity. Over-education is permanent for many workers since around 50 percent of workers over-educated in 1991 are still over-educated in 2005. However, we also show that these workers are of lower quality compared to around 25 percent who find a match within five years of being over-educated. Finally, there is a significant scarring effect for workers over-educated in 1991 since they never fully reach parity compared to those who were matched in 1991, although this is not the case for graduates who manage to find a match within 5 years

Vertical occupational mobility and its measurement

This paper describes a number of alternative approaches to devising a vertical occupational scale and compares the outcomes of different scales on calculations of occupational mobility. The paper describes the conceptual issues relevant to calculating occupational mobility and documents the measurement error embedded in the choice of measure, as applied to different data sets. The ranking schemes used include SOC (9) major codes ranked by mean occupational hourly earnings, Hope-Goldthorpe collapsed 36-point scores, a 15-category SOC ranking based on educational qualifications, and a 77 category ranking based on 2-digit SOC90 occupations, wage rates, educational qualifications, training and job tenure. These ranking schemes are applied to data from the 1958 NCDS cohort between the ages of 23 to 33 and 33 to 42, and to 1.25 year transitions in the Quarterly Labour Force Survey panel data. The calculations carried out show that variations in the extent of vertical occupational mobility, both upward and downward, had systematic elements. The extent of mobility was found to vary by the composition of the individuals´ data particularly in terms of lifecourse stages and gender, the number of categories in the ranking scheme, attrition in the data and flows out of employment over the mobility period, and changes in labour market conditions over time. However, the sizes of these effects were very variable

A process activity monitor for AOS/VS

With the ever increasing concern for computer security, users of computer systems are becoming more sensitive to unauthorized access. One of the initial security concerns for the Shuttle Management Information System was the problem of users leaving their workstations unattended while still connected to the system. This common habit was a concern for two reasons: it ties up resources unnecessarily and it opens the way for unauthorized access to the system. The Data General MV/10000 does not come equipped with an automatic time-out option on interactive peripherals. The purpose of this memorandum is to describe a system which monitors process activity on the system and disconnects those users who show no activity for some time quantum

Using Financial Incentives and Improving Information to Increase Labour Market Success: A Non-Parametric Evaluation of the 'Want2Work' Programme

The `Want2Work´ programme was designed to help individuals back into work. This article uses propensity score matching to evaluate the success of a policy that cannot otherwise be evaluated using standard parametric techniques. Using a range of estimation methods, sub-samples and types of job, the scheme was successful. Our most conservative estimates indicate that participants were 4-7 percentage points more likely to find employment than a control group of non-treated job-seekers. Effects were even stronger for Incapacity Benefit recipients. Moreover, there is little evidence that participants were placed in low quality or temporary jobs
