This thesis contributes to the empirical strands of the economic literature that explore and investigate the effects of public policies on individuals and firms. The first chapter provides a novel empirical test of human capital theory by studying whether increases in residual working life induce additional training. By exploiting a sizable pension reform, that affected all Italian workers, in a Difference-in-Differences setting there is evidence that an increase in the residual working life increases human capital investment. Additionally, the response to the reform was very heterogeneous and depending on gender, age profiles, education, martial status, sector of employment and firm size. However, the empirical evidence suggests to rule out that positive variations in human capital investment were directly sponsored by employers. The second chapter studies the impact of the COVID-19 pandemic on female economists' research productivity. The analysis uses data from the SSRN web archive on 4,778 distinct pre-prints involving 8,651 authors from over 90 countries observed from January to November 2020. By estimating a Difference-in-Differences, the estimates show that, since the lockdown began, the number of working papers written by a female economist, alone or jointly with other researchers, uploaded on SSRN declined of about 20 percentage points and this negative effect persists up to about 4 months later. Declines in productivity, however, disappear during the school re-opening period suggesting that indeed childcare demand has been an important channel in causing women production drop. Finally, declines in productivity are not associated with increases in pre-prints' quality. The third chapter provides novel empirical evidence on the effectiveness of public subsidies for SMEs by investigating the effect of a subsidy program taken place in Campania (South Italy) in 2013. By relying on a Difference-in-Differences approach, the empirical analysis demonstrates that the regional program was effective in increasing private firms' spending in innovative investment. However, the firms' response to the program was also largely heterogeneous. In particular, there is evidence that the positive effect on investment comes from micro- and small-sized firms as well as firms operating in high tech sectors and high tech service firms. Nonetheless, it is not possible to reject the hypothesis that firms increased spending by about approximately the amount of the subsidy. Finally, the program had sizeable spillover effects on labour demand but not on firms' productivity.
