There is a small but growing literature on the determinants of social capital. Most of these studies use a measure of trust to define social capital empirically. In this paper we use three different measures of social capital: the size of the individual’s social network, the extent of their...

This paper studies the effects of local marriage markets on South African women’s marital decisions. The analysis is motivated by the low proportion of married among African mothers since 48% are never married. This means that the children of all these never married mothers have no access to...

This paper analyzes the time allocation of Italian spouses to paid work, childcare and household work. The literature suggests that Italian husbands contribute the least to unpaid household work, relative to other European countries, while Italian women have the lowest market employment rates....

Teenage motherhood is very high in South Africa. In 2001, 55 per thousand African South African women and 82 per thousand Coloured South African women were teenage mothers as compared to 8 among Indian South Africans and 3 among White South African women. In this paper we use the South African...

This paper focuses on the time allocation of spouses and the impact of economic variables. We present a stylized model of the time allocation of spouses to illustrate the expected impact of wages and non-labour income. The empirical model simultaneously specifies three time-use choices -paid...

We present a new framework for the joint estimation of the default-free government term structure and corporate credit spread curves. By using a data set of liquid, German mark denominated bonds, we show that this yields more realistic spreads than traditionally obtained spread curves that...

At the time of writing this article, Fourier inversion is the computational method of choice for a fast and accurate calculation of plain vanilla option prices in models with an analytically available characteristic function. Shifting the contour of integration along the complex plane allows for...

In this paper we derive a market value for Guaranteed Annuity Option using martingale modeling techniques. Furthermore, we show how to construct a static replicating portfolio of vanilla interest rate swaptions that replicates the Guaranteed Annuity Option. Finally, we illustrate with historical...

When using an Euler discretisation to simulate a mean-reverting square root process, one runs into the problem that while the process itself is guaranteed to be nonnegative, the discretisation is not. Although an exact and efficient simulation algorithm exists for this process, at present this...

The characteristic functions of many affine jump-diffusion models, such as Heston’s stochastic volatility model and all of its extensions, involve multivalued functions such as the complex logarithm. If we restrict the logarithm to its principal branch, as is done in most software packages,...
