Title:  Timed to say goodbye: Does unemployment benefit eligibility affect worker layoffs?
Authors:  Andrea Albanese, Corinna Ghirelli, Matteo Picchio
We study how unemployment benefit eligibility affects the layoff exit rate by exploiting quasiexperimental variation in eligibility rules in Italy. By using a difference-in-differences estimator, we find an instantaneous increase of about 12% in the layoff probability when unemployment benefit eligibility is attained, which persists for about 16 weeks. These findings are robust to different identifying assumptions and are mostly driven by jobs started after the onset of the Great Recession, in the South and for small firms. We argue that the moral hazard from the employer's side is the main force driving these layoffs.

Title: Sources and determinants of responsible innovations: occupational health and safety in italian firms
Authors: Marialuisa Divella, Alessandro Sterlacchini
This paper provides a micro-econometric analysis of the factors facilitating the introduction of responsible innovations by firms, with a focus on those aimed at improving occupational health and safety. These innovations have been rarely investigated with quantitative methods, especially if compared to those aimed at protecting the environment. Accordingly, we also assess whether firms pursuing health and safety innovations are also those ascribing high importance to the reduction of environmental impacts. The evidence provided by using firm-level data taken from the Italian Community Innovation Surveys highlights the key role played by some external sources of knowledge and internal human resource practices for the achievement of responsible innovations. Many similarities but also important differences between firms emerge, according to whether they are committed to health and safety or environmental innovation.

Title: Macro and Micro Prudential Policies: Sweet and Lowdown in a Credit Network Agent Based Model
Authors: Ermanno Catullo, Federico Giri, Mauro Gallegati
The paper presents an agent based model reproducing a stylized credit network that evolves endogenously through the individual choices of rms and banks. We introduce in this framework a anancial stability authority in order to test the e ects of different prudential policy measures designed to improve the resilience of the economic system. Simulations show that a combination of micro and macro prudential policies reduces systemic risk, but at the cost of increasing banks' capital volatility.
Moreover, agent based methodology allows us to implement an alternative meso regulatory framework that takes into consideration the connections between firms and banks. This policy targets only the more connected banks, increasing their capital requirement in order to reduce the di usion of local shocks. Our results support the idea that the meso prudential policy is able to reduce systemic risk without a ecting the stability of banks'capital structure.

Title: Health spending in Italy: the impact of immigrants
Authors: Giulia Bettin, Agnese Sacchi
The welfare impact of immigration is a hot topic especially for countries at the external borders of the European Union. This paper studies how immigrants affect public health expenditure across Italian regions during the period 2003-2015. Identification strategy is based on shift{share instruments, which are also robust to pull factors that might attract immigrants in Italy and to internal migration of natives. We find that a 1 percentage point increase in immigrants over total population leads to a decrease in public health expenditure per capita by about 3.9% (i.e. around 70 euro per capita). This evidence is confirmed when focusing on needy immigrants from low income countries with less developed welfare systems. Among possible channels, we find no
support for any crowding out effects from public to private health services by natives due to increasing immigration neither for the effect of entry barriers limiting the immigrants' reliance on public healthcare. Our results are driven by immigrants' demographic structure: foreigners are mostly males and younger workers that call for less health spending, according to a positive selection mechanism.
