Kind of Black: The Musicians' Labour Market in Italy

It is estimated that only 5 per cent of musicians in Italy are regularly employed. In an attempt at understanding such a peculiar situation, we build a theoretical model of the musicians' labour market in which we embed the main institutional features of the Italian system. The presence of taxation encourages the formation of a black labour market for musicians and discourages talented agents from becoming full‐time musicians in all second‐best economies. In Italy both tendencies are particularly strong, and exacerbated by the peculiarities of the pension system for musicians. These inefficiencies might be corrected by a twofold policy: the reform of the pension system, highly desirable but unlikely to be politically feasible in the current Italian institutional setting, and the introduction of a sufficiently large unemployment benefit for musicians, step that has a general interest for any second‐best economy and not only for the case of the musicians' labour market, and that might instead be viable under certain circumstances.     

The Access of the Young Graduates in Sciences into R&D Profession: A Switching Model Treatment for the French Case

We address the question concerning the choice of graduates in sciences and engineering to look for employment in research and development. We use an endogenous switching regression to avoid the existence of self‐selection biases. The study shows that human capital is decisive where both employment opportunities and remuneration are concerned within, but not without, this sector. The results also suggest that in the early stages of a career, the R&D sector is less rewarding than other types of employment only for doctors and not for graduates from engineering schools.     

IMMIGRATION,WAGES, AND COMPOSITIONAL AMENITIES

There is strong public opposition to increased immigration throughout Europe. Given the modest economic impacts of immigration estimated in most studies, the depth of anti‐immigrant sentiment is puzzling. Immigration, however, does not just affect wages and taxes. It also changes the composition of the local population, threatening the compositional amenities that natives derive from their neighborhoods, schools, and workplaces. In this paper we use a simple latent‐factor model, combined with data for 21 countries from the 2002 European Social Survey (ESS), to measure the relative importance of economic and compositional concerns in driving opinions about immigration policy. The ESS included a unique battery of questions on the labor market and social impacts of immigration, as well as on the desirability of increasing or reducing immigrant inflows. We find that compositional concerns are 2–5 times more important in explaining variation in individual attitudes toward immigration policy than concerns over wages and taxes. Likewise, most of the difference in opinion between more‐ and less‐educated respondents is attributable to heightened compositional concerns among people with lower education.     

AN INTERNATIONAL COMPARISON OF LIFETIME INEQUALITY: HOW CONTINENTAL EUROPE RESEMBLES NORTH AMERICA

We compare earnings inequality and mobility across the United States, Canada, France, Germany and the United Kingdom during the late 1990s. A flexible model of earnings dynamics that isolates positional mobility within a stable earnings distribution is estimated. Earnings trajectories are then simulated, and lifetime annuity value distributions are constructed. Earnings mobility and employment risk are found to be positively correlated with base‐year inequality. Taken together they produce more equalization in countries with high cross‐section inequality such that the countries in our sample have more similar lifetime inequality levels than cross‐section measures suggest.     

COMPETITION AND RELATIONAL CONTRACTS: THE ROLE OF UNEMPLOYMENT AS A DISCIPLINARY DEVICE

Abstract When workers are faced with the threat of unemployment, their relationship with a particular firm becomes valuable. As a result, a worker may comply with the terms of a relational contract that demands high effort even when performance is not enforceable by a third party. But can relational contracts motivate high effort when workers can easily find alternative jobs? We examine how competition for labor affects the emergence of relational contracts and their effectiveness in overcoming moral hazard in the labor market. We show that effective relational contracts do emerge in a market with excess demand for labor. Long‐term relationships turn out to be less frequent when there is excess demand for labor than they are in a market characterized by exogenous unemployment. However, stronger competition for labor does not impair labor market efficiency: higher wages induced by competition lead to higher effort out of concerns for reciprocity.     

THE RELATIONSHIP BETWEEN CHILD HEALTH,DEVELOPMENTAL GAPS,AND PARENTAL EDUCATION: EVIDENCE FROM ADMINISTRATIVE DATA

We use administrative German data to examine the role of physical and mental health conditions in explaining developmental gaps between children whose parents have different educational levels. Specifically, we employ sibling fixed effect models to estimate the effect of a comprehensive list of childhood health conditions—diagnosed by government physicians—on the cognitive and verbal ability of pre‐school children. We also apply decomposition methods to examine the extent to which gaps in child development can be attributed to child health conditions. While most physical health conditions have small and insignificant effects, mental health conditions, in particular hyperactivity, have a large and significant effect on development. Mental health conditions account for 14%–36% of the gap in cognitive ability and for 23%–24% of that in verbal ability. Thus, policies aimed at reducing disparities in child development and socioeconomic inequalities later in life should focus more on the early diagnosis and effective treatment of mental health conditions.     

ROUTES OF INFECTION: EXPORTS AND HIV INCIDENCE IN SUB‐SAHARAN AFRICA

This paper estimates whether exports affect the incidence of HIV in Africa. This relationship has implications for HIV prevention policy as well as for the consequences of trade increases in Africa. I estimate this impact using two sources of data on HIV incidence, one generated based on UNAIDS estimates and the other based on observed HIV mortality. These data are combined with data on export value and volume. I find a fairly consistent positive relationship between exports and new HIV infections: doubling exports leads to a 10%–70% increase in new HIV infections. Consistent with theory, this relationship is larger in areas with higher baseline HIV prevalence. I interpret the result as suggesting that increased exports increase the movement of people (trucking), which increases sexual contacts. Consistent with this interpretation, the effect is larger for export growth than for income growth per se and is larger in areas with more extensive road networks.     

Employability of Young Italian Men after a Jobless Period, 1989–98

In this paper we investigate the existence of negative jobless duration dependence and the impact of jobless spells on future wages. Our findings are somewhat out of line compared with analogous explorations. We find evidence of very long unemployment duration of the young male labor force, higher than reported anywhere else in Western Europe, as well as large negative unemployment duration dependence. On the other hand, young Italian men experiencing jobless periods in their early careers face small re‐employment wage losses. Such losses do increase with the duration of joblessness, but they are lower than reported in the USA, Canada, the UK, France, and Spain.     

Informal Referrals,Employment, and Wages: Seeking Causal Relationships

Employers and job seekers rely extensively on informal referrals to fill vacancies or to find a job. The widespread use of job contacts has been largely associated with labor outcomes, such as finding a job or even affecting wages. This paper explores whether the use of informal referrals on the job search process affects labor market outcomes of Colombian urban workers. Results indicate that informal referrals are slightly more successful than other job search strategies in term of job seeker's placement. However, referred workers earn in average less than their non‐referred counterparts. Yet, this is only true in formal‐sector positions.     

Firm Size and Employment Dynamics: Estimations of Labor Demand Elasticities Using a Fractional Panel Probit Model

This paper examines the comprehensive discussion on the relationship between job creation, or destruction and firm size. More specifically, the study will determine whether the argument about small‐ and medium‐sized enterprises (SMEs) showing higher employment dynamics is confirmed or not. As such, the following work applies elasticities from a standard labor demand model derived from the estimations of fractional probit models for panel data, as process recommended in Papke and Wooldridge [2008; Journal of Econometrics 145(1–2): 121–133]. Elasticities are a useful measure of employment dynamics, if it is assumed that SMEs act on the same markets. The elasticity results from German establishment data illustrate that firm size does matter for the increase or decrease of employment. SMEs with less than 10 workers exhibit a higher employment dynamic, compared with other entities, at each respective percentile in the distribution of the wage share. Additionally, the outcome of the analysis weakly confirms the hypothesis that smaller firms are more restricted to capital markets, compared with large entities. The results also illustrate that firm size only explains one aspect of job creation and destruction. As stated in the well‐known Hicks–Marshall rules for elasticities of factor demand, the results illustrate that the reaction of labor demand on economic changes increases with the share of labor. Firms with a high share of labor also have larger elasticities, compared with firms with a strong use of capital. Both effects, the size effect and the effect of the proportion of labor, would blend in reality, and therefore, possibly lead to controversial results for the relationship between firm size and employment dynamics. In addition, a model with a negative relationship among both variables is too simple to explain the behavior of firms.
