We investigate the effects of two reforms of temporary employment using panel data on Italian firms. We exploit variation in their implementation across regions and sectors for identification. We find that the reform of apprenticeship contracts increased job turnover and induced the substitution of external staff with firms' apprentices, with an overall productivity-enhancing effect. The reform of fixed-term contracts instead did not produce the intended results: it induced a substitution of temporary employees in favour of permanent ones and reduced capital intensity, generating productivity losses. We estimate substitution elasticities across types of temporary contracts that are consistent with these interpretations.

We investigate the effect of social interactions on labor market outcomes using a direct measure of social contacts based on information about individuals' three best friends and their characteristics. We examine the effect of the number of employed friends on the transition from non-employment to employment, and we find the existence of significant network effects at the individual level. An additional employed friend increases the probability of finding a job by 3.7 percentage points. This finding is robust to specifications that address the endogeneity of friends' employment status, which may be induced by correlation with unobserved individual attributes and feedback effects. Considering labor market outcomes, we find evidence of higher wages and employment stability for those with more employed friends, which is consistent with networks acting as an information transmission mechanism.

Using an unbalanced panel of Italian male wages covering the 1974–88 interval, in this study we estimate the parameters of the wage covariance structure by minimum distance. Estimated variance components models allow for a linear trend in permanent wages, so that wage profile convergence can be assessed by considering the covariance between intercepts and slopes of such individual trends. Evidence of permanent wage convergence is found in the overall wage distribution, but not within white collar workers data; this contrasts with human capital interpretations of wage dynamics and suggests that other factors, such as the egalitarian wage‐setting framework fully effective until the mid‐1980s, could have played a major role in shaping the wage distribution.

Abstract In this paper we study the determinants of volunteering. We depart from previous literature that considers only economic incentives and investigate the role that extrinsic and intrinsic motivations play in shaping the supply of voluntary labour. We build on previous theoretical research and derive a framework for interpreting results from our econometric analysis. We consider a sample of Italian workers of which we can observe proxies of motivations and volunteering choices in three different sectors: social services, political activism and union activism. We make due allowance for the endogeneity of motivations and show that both types of motivations have an effect on volunteering. Consistently with theoretical models, we find extrinsic motivations to lower voluntary labour supply, whereas the opposite holds for intrinsic motivations.
