Capital requirements and business cycle regimes: Forward-looking modelling of default probabilities

Journal of Banking & Finance 2005 29(12), 3121-3140 open access
This paper proposes a forward-looking model for time-varying capital requirements, which finds application within Basel II. The model rests on the relationship between default rates and the business cycle: by positing two regimes, expansion and recession, and by forecasting the associated probabilities, the default probability for each rating class is defined as the expected value of a default rate whose distribution is a mixture of an expansion and a recession distribution. The application to US data over the forecasting period 1971–2002 provides evidence that the model makes it possible to preserve the risk sensitivity of the capital requirement and at the same time to dampen procyclicality.

Household preferences for socially responsible investments

Journal of Banking & Finance 2019 105, 107-120 open access
We analyze revealed and stated household preferences for socially responsible investments (SRI). Using a questionnaire specifically designed for this purpose and administered to a Dutch representative household panel, we investigate the actual and latent demand for SRI products. Respondents reported whether they owned SRI products, the reason behind this decision, but also answered stated choice questions on traditional investments and hypothetical SR products with an explicit return penalty and/or an in-kind compensation. Our results show that social investors are willing to pay a price to be socially responsible rather than needing a little nudge, such as a gift (a book or a voucher). Highly educated individuals have a substantial latent demand that is currently unexploited. Keeping education constant, individuals who consider themselves financially literate are less interested in SR products than others. Particularly at the intensive margin, the stated demand for SRI funds is sensitive to the return penalty.

Marriage and other risky assets: A portfolio approach

Journal of Banking & Finance 2011 35(11), 2902-2915 open access
We study the joint impact of gender and marital status on financial investments by testing the hypothesis that marriage represents – in a portfolio framework – a sort of safe asset and that this attribute may change over time. We show that married individuals have a higher propensity to invest in risky assets than single ones, that this marital status gap is stronger for women and that, for women only, it evolves and declines at the end of the sample period. Next we explore a number of possible explanations of the observed gender differences by controlling for background factors that capture the evolution of family and society. We find that both the higher female marital status gap and its time variability vanish for those women who are employed. Our empirical investigation is based on a dataset drawn from the 1993–2006 Bank of Italy Survey of Household Income and Wealth.
