Wage Dispersion and Equilibrium Search Models: Some Evidence from Italy
No full textThis paper provides a structural estimation of an equilibrium search model with on-the-job search and heterogeneity in firms' productivities using a sample of Italian male workers. Results indicate that arrival rates of offers for workers are higher when unemployed than when employed and firms exploit their monopsony power when setting wages. As a result, workers earn far less than their marginal product. The model is then used to study regional labour market differentials in Italy. Wide variation in frictional transition parameters across areas helps to explain persistent unemployment and wage differentials. Copyright 2008 The Author.

Il sostrato linguistico e culturale nell’Autobiografia di Vincenzo Sulis
No full textIl contributo indaga gli affioramenti ancora non rilevati e la produttività del sostrato locale sardo nell’Autobiografia di Vincenzo Sulis, movendosi sulla scorta delle osservazioni di Francesco Alziator e in debita continuità con gli studi finora dedicati al testo dalla critica. Com’era prevedibile, l’esame a un tempo filologico e linguistico dell’Autobiografia permette di cogliere, oltre ai molti indicatori del codice primario soggiacente (dall’aspetto grafo-fonetico al livello lessicale e sovralessicale), gli apporti più latamente mediterranei agli usi linguistici della Sardegna in età preunitaria, di cui la scrittura memorialistica di Sulis offre un campione schietto e vivace, specie per ciò che riguarda i modismi e le unità fraseologiche censiti. Il quadro risultante dall’articolo delinea così un contesto di sincretismo culturale, oltre che meramente linguistico, assai indicativo e suscettibile di ulteriori approfondimenti
Measuring students'assessemnts on university course quality using mixed-effects models
No full textIn this work a generalized Item Response Model has been considered in order
to analyze students’ perceived quality of university course. The approach allows the
author to pursue several tasks in the estimation of item and person parameters. Namely:
(i) it allows to jointly model students’ answers to the whole set of indicator items; (ii)
it considers the dimensionality of the items composing the test by explicitly specifying
more than one latent trait; (iii) it evaluates the effect of significant characteristics on students’
perception of the latent traits; (iv) it takes into account the ‘intra-cluster’ variability
which affect ratings at course level. Moreover, by moving from the posterior estimates at
individual and course level, it has been possible to make pairwise comparisons between
courses and students on the bases of their levels of perceived quality
Employment protection and firm-provided training in dual labour markets
No full textIn this paper we leverage a labour market reform (Fornero Law) which reduced firing restrictions for open-ended contracts in the case of firms with more than 15 employees in Italy. The results from a Difference in Regression Discontinuities design demonstrate that after the reform, the number of trained workers increased in firms just above the threshold by approximately 1.5 additional workers. We show that this effect can be explained by the reduction in worker turnover and a higher use of permanent contracts. Our study highlights the potentially adverse effects of employment protection legislation on training in dual labour markets
