Using a modified version of the method proposed by Ackerberg et al. (2006) that takes into account unobserved heterogeneity, an augmented production function with excess worker turnover entering as the regressor of interest is estimated. The main result is that replacing workers is beneficial to firm productivity. A 1 standard deviation increase in the excess worker turnover rate is estimated to increase productivity by 0.81%. The possibility of finding more suitable employer-employee matches and the presence of knowledge spillover effects are seen as the main determinants of the impact. Robustness checks indicate that the impact has an inverted U-shape, suggesting that, beyond a certain point, replacing workers ends up being harmful. However, since about 90% of firms lie before this point, increases in excess worker turnover are beneficial for the vast majority of them. They also suggest that the effect is diversified across different categories of firms. High-tech firms and firms belonging to industrial districts benefit the most from excess worker turnover. On the contrary, young and very small firms seem to suffer from it. Elena Grinza, Ph.D. - Curriculum Vitae 2/6

3 Abstract Abstract The Impact of Part-time Work on Firm Total Factor Productivity: Evidence from Italy (with Francesco Devicienti and Davide Vannoni), IZA Discussion Papers No. 9463, 2015 In this paper, we explore the impact of part-time work on firm productivity. Using a large panel data set of Italian corporations balance sheets for the period , we first estimate the total factor productivity (TFP) of each firm for each year. We use different approaches aimed at solving input simultaneity, including a version of Ackerberg et al. s (2006) control function approach, which accounts for firm fixed effects. We then match the TFP estimates with rich information on the firms use of part-time work obtained from survey data and estimate the impact of part-time work on TFP at the firm level. We find that an increase of 1 standard deviation in the part-time share reduces TFP by 2.03%. The results suggest that this harmful effect stems from horizontal rather than vertical part-time arrangements. We also find that firms declaring that they use part-time work to accommodate workers requests suffer the most. Moreover, we show that the so-called flexible and elastic clauses are successful in reducing the negative impact associated with part-time work. Are Female Managers Really Heartless? Evidence from the Use of Part-time Work in Italy Using three waves of a uniquely rich firm-level survey on Italian companies, I investigate the impact of female managers on the use of part-time work. I find that, in general, female managers are associated with lower levels of part-time work. This result is confirmed after controlling for a large set of observable confounding factors and unobserved heterogeneity. Exploiting information on whether the firm uses part-time work to accommodate workers requests for shorter working hours or, alternately, because it satisfies the firm s needs, I find that only in the latter case female managers behave differently from male managers and have a significant and large negative impact on the use of part-time work. I provide evidence that this result may stem from female managers limiting the phenomenon of involuntary part-time work. Work in Progress Does It Matter Where?
