Child development and success or failure in the youth labor market

Book description: The economic status of young people has declined significantly over the past two decades, despite a variety of programs designed to aid new workers in the transition from the classroom to the job market. This ongoing problem has proved difficult to explain. Drawing on comparative data from Canada, Germany, France, Sweden, and the United Kingdom, these papers go beyond examining only employment and wages and explore the effects of family background, education and training, social expectations, and crime on youth employment. This volume brings together key studies, providing detailed analyses of the difficult economic situation plaguing young workers. Why have demographic changes and additional schooling failed to resolve youth unemployment? How effective have those economic policies been which aimed to improve the labor skills and marketability of young people? And how have youths themselves responded to the deteriorating job market confronting them? These questions form the empirical and organizational bases upon which these studies are founded

Crime and Economic Incentives

We explore the role that economic incentives, particularly changes in wages at the bottom end of the wage distribution, play in determining crime rates. We use data on the police force areas of England and Wales between 1975 and 1996. We find that falls in the wages of unskilled workers leads to increases in crime. We carry out a number of experiments with different wage measures, including a wage measure that accounts for the effects of changes in the composition of employment. These reinforce the picture of a strong impact of wages on crime. The result that incentives play a central role is reinforced further by the strong impact on crime of deterrence measures and of a measure of the returns to crime

Human resource management as a substitute for trade unions in British workplaces

The authors use British workplace data for 1980–98 to examine whether increased human resource management (HRM) practices coincided with union decline, consistent with the hypothesis that such practices act as a substitute for unionization. Two initial analyses show no important differences between union and non-union sectors or between newer workplaces (which are likelier to be non-union) and older ones in the pattern of HRM practices over time; and the study’s longitudinal analysis picks up no evidence of faster union decline in workplaces or industries that adopted HRM practices than in those that did not. Not only is the hypothesized substitution effect thus not supported, but the authors even uncover some evidence of a complementarity between unions and HRM practices. The authors conclude that increased use of HRM practices is probably not an important factor underpinning union decline in Britain

Panic on the streets of London

The terrorist attacks of 7 July 2005 resulted in a very large redeployment of police officers to central London boroughs. New research by Mirko Draca, Stephen Machin and Robert Witt looks at the impact of this increased security presence on criminal activity in the weeks and months after the bomb blasts

Implications of skill-biased technological change: international evidence

Demand for less skilled workers decreased dramatically in the US and in other developed countries over the past two decades. WE argue that pervasive skill-biased technological change, rather than increased trade with the development world, is the principal culprit. The pervasiveness of this technological change is important for two reasons. Firstly, it is an immediate and testable implication of technological change. Secondly, under standard assumptions, the more pervasive the skill-biased technological, the greater the increase in the embodied supply of less skilled workers and the greater the increase in the embodied supply if less skilled workers and the greater the increases in the embodied supply of less skilled workers and the greater the depressing effect on their relative wages through world goods prices. In contrast, in the Heckscher-Ohlin model with small open economies the skill-bias of local technological changes does not affect wages. Thus, pervasiveness deals with a major criticism of skill-biased technological as a cause. Testing the implications of pervasive, skill-biased technological change, we find strong supporting evidence. Firstly, across the OECD, most industries have increased the proportion of skilled workers employed, despite rising or stable relative wages. Secondly, increases in demand for skills were concentrated in the same manufacturing industries in different developed countries

Market regulation and firm performance: the case of smoking bans in the UK

This paper analyzes the effects of a ban on smoking in public places upon firms and consumers. It presents a theoretical model and tests its predictions using unique data from before and after the introduction of smoking bans in the UK. Cigarette smoke is a public bad, and smokers and non-smokers differ in their valuation of smoke-free amenities. Consumer heterogeneity implies that the market equilibrium may result in too much uniformity, whereas social optimality requires a mix of smoking and non-smoking pubs (which can be operationalized via licensing). If the market equilibrium has almost all pubs permitting smoking (as is the case in the data) then a blanket ban reduces pub sales, profits, and consumer welfare. We collect survey data from public houses and find that the Scottish smoking ban (introduced in March 2006) reduced pub sales and harmed medium run profitability. An event study analysis of the stock market performance of pub-holding companies corroborates the negative effects of the smoking ban on firm performance

Economics of education research: a review and future prospects

In this paper we offer an appraisal of the economics of education research area, charting its history as a field and discussing the ways in which economists have contributed both to education research and to education policy-making. In particular, we highlight the theoretical and methodological contributions that economists have made to the field of education during the last 50 years. Despite the success of the economics of education as a field of inquiry, we argue that some of the contributions made by economists could be limited if the economics of education is seen as quite distinct from the other disciplines working in the field of education. In these areas of common interest, economists need to work side by side with the other major disciplines in the field of education if their contribution to the field is to be maximised, particularly in terms of applying improved methodology. We conclude that the study of education acquisition and its economic and social impact in the economics of education research area is very likely to remain a fertile research ground. Acknowledgement

Patients with Essential thrombocythaemia have an increased prevalence of antiphospholipid antibodies which may be associated with thrombosis

A significant proportion of patients with Essential Thrombocythaemia (ET) have thrombotic complications which have an important impact upon the quality, and duration of their life. We performed a retrospective cross sectional study of the prevalence of antiphospholipid antibodies (APA) in 68 ET patients. Compared to 200 elderly controls (> 50 years) there was a significant increase in anticardiolipin IgM (p < 0.0001) and anti β2 glycoprotein I (anti-β2GPI) IgM (p < 0.0001) antibodies in ET. Thrombosis occurred in 10/20 with APA and 12/48 without, p = 0.04, relative risk 2.0 (95% confidence intervals 1.03-3.86); these patients did not differ in terms of other clinical features. The prevalence of thrombosis in patients with dual APA (6/7) was significant when compared to those with single APA (p = 0.02) and the remaining patients (p < 0.0002). Also anti-β2GPI IgM antibodies either alone, or in combination with another APA, were associated with thrombosis (p = 0.02). These results suggest that the prevalence of APA in ET and their influence upon thrombotic risk merit investigation in a larger study

Floppy swimming: Viscous locomotion of actuated elastica

Actuating periodically an elastic filament in a viscous liquid generally breaks the constraints of Purcell's scallop theorem, resulting in the generation of a net propulsive force. This observation suggests a method to design simple swimming devices - which we call "elastic swimmers" - where the actuation mechanism is embedded in a solid body and the resulting swimmer is free to move. In this paper, we study theoretically the kinematics of elastic swimming. After discussing the basic physical picture of the phenomenon and the expected scaling relationships, we derive analytically the elastic swimming velocities in the limit of small actuation amplitude. The emphasis is on the coupling between the two unknowns of the problems - namely the shape of the elastic filament and the swimming kinematics - which have to be solved simultaneously. We then compute the performance of the resulting swimming device, and its dependance on geometry. The optimal actuation frequency and body shapes are derived and a discussion of filament shapes and internal torques is presented. Swimming using multiple elastic filaments is discussed, and simple strategies are presented which result in straight swimming trajectories. Finally, we compare the performance of elastic swimming with that of swimming microorganisms.Comment: 23 pages, 6 figure

Inequality in Higher Education and the Labor Market

Understanding the link between socioeconomic status and access to higher education (HE) is an important challenge for understanding how governments can better promote social mobility. Inequality in higher education participation, coupled with a positive significant wage return to HE, has clear implications for income inequality and lower future rates of social mobility. For example, the Scandinavian countries have more equal access to higher education which, together with smaller wage differentials due to higher education in the labor market, results in a relatively equal society. On the other hand, in countries such as the United Kingdom and the United States, access to higher education is highly determined by individuals’ background. This, coupled with bigger wage returns to degrees..
