Training subsidies and the wage returns to continuing vocational training: Evidence from Italian regions

We use the regional and time variation of training grants in Italy to identify the causal effect of (formal continuing vocational) training on earnings. We estimate log-linear earnings regressions with constant marginal returns to training and find that one additional week of training increases monthly net earnings by 1.36%, substantially less than the 3% or more often found in the literature. Estimated returns vary significantly by firm size, and range from 0.40% in firms with more than 100 employees to 2.51% in smaller firms, the bulk of the Italian private sector. A simple back of the envelope comparison of the marginal costs and benefits of training policy suggests that the latter are higher than the former.     

Multiple attractors and global bifurcations in a Kaldor-type business cycle model

We consider a Kaldor-type discrete-time nonlinear business cycle model in income and capital, where investment is assumed to depend both on the difference between normal and current levels of capital stock, and on the difference between the current income and its normal level, through a nonlinear S-shaped increasing function. As usual in Kaldor business cycle models, one or three steady states exist, and the standard analysis of the local stability and bifurcations suggests that endogenous oscillations occur in the presence of only one unstable equilibrium, whereas the coexistence of three equilibria is characterized by bi-stability, the central equilibrium being on the boundary which separates the basins of the two stable ones. However, a deeper analysis of the global dynamic properties of the model in the parameter ranges where three steady states exist, reveals the existence of an attracting limit cycle surrounding the three steady states, leading to a situation of multistability, with a rich and complex dynamic structure.     

Monetary policy,ownership structure,and risk-taking at financial intermediaries

This paper examines how ownership structure interacts with monetary policy in shaping financial intermediaries' appetite for risk. By constructing a large panel of banks across Western Europe, we provide evidence that differences in bank ownership influence the transmission of monetary policy via the risk-taking channel. While shareholder banks actively adjust the riskiness of their portfolios to changes in interest rates, stakeholder banks appear to be less responsive to such changes. These findings call for greater attention to the nature of bank ownership when setting monetary policy.     

Corporate codes of ethics and cash holdings: International evidence

In the presence of agency costs, managers retain cash for their own benefit at the expense of shareholder wealth. Extending prior literature on the role of corporate governance in mitigating the effects of agency conflicts on corporate cash holdings, we study a governance mechanism that has largely been overlooked, namely, corporate codes of ethics. We find a negative association between code of ethics quality and cash holdings, which suggests that managers hold less cash when the firm has a strong code of ethics in place. The effect is greater when agency costs are elevated due to weaker country-level investor protections. We also find that payouts and the marginal value of cash holdings to investors are increasing in code quality. Overall, our results are consistent with codes of ethics helping to limit opportunistic behaviour from managers when determining the firm's level of cash holdings.     

Effect of grandchildren on the happiness of grandparents: Does the grandparent's child's gender matter?

Using a representative sample from Japan and a difference-in-differences strategy, we investigate whether the effect of having grandchildren on the happiness of grandparents varies with the gender of their (own) single child. In line with our expectations, we find that maternal grandmothers have more to lose or less to gain from having grandchildren than paternal grandmothers. In contrast, grandfathers’ changes in happiness do not depend on their own child's gender. This result is explained by the fact that grandmothers are more likely to be involved in childrearing when their daughter has a child.
