An impact of environment on mortality, similar to survival analysis, is often modeled by the proportional hazards model, which assumes the corresponding comparison with a baseline environment. This model describes the memory-less property, when the mortality rate at a given instant of time...

Increasing proportions of couples are making childbearing decisions in stepfamilies but there has been no general comparative picture across European countries on stepfamily formation. The present paper aims to fill this gap and provides a comparison of European countries using macro-level...

A system subject to a point process of shocks is considered. Shocks occur in accordance with a nonhomogeneous Poisson process. Different criterions of system failures are discussed in a homogeneous case. Two natural settings are analyzed. Heterogeneity is modeled by an unobserved univariate...

Interpersonal relationships of support have been found to be an important factor in individual fertility intentions in Central and Eastern European countries. The foundations of this positive influence have not been well explored to date, however. We present a theoretical discussion on...

In this paper we analyse the leaving home experience of men and women born around 1960 in 16 European countries. We use extensive empirical evidence from Fertility and Family Survey data, providing a large-scale comparison. We focus on some key indicators of the process of leaving home: the...

Models on the impact of social networks on reproductive behavior primarily address processes of interpersonal influence on fertility related values and utility perceptions and consider aspects of social support and social capital only to a small extend. On the basis of an exchange theoretical...

Bongaarts and Feeney (1998) have recently proposed an adjusted total fertility rate to disentangle tempo effects from changes in the quantum of fertility. We propose an extension to the Bongaarts and Feeney formula that includes variance effects, i.e., changes in the variance of the fertility...

The standardised rate of third births declined by over 50 percent in Austria between the late 1970s and the mid-1990s. The third birth was also postponed gradually over the years up through 1991-92, after which the tempo of childbearing suddenly increased in response to a change in the...

Some stochastic approaches to biological aging modeling are studied. We assume that an organism acquires a random resource at birth. Death occurs when the accumulated dam-age (wear) exceeds this initial value, modeled by the discrete or continuous random vari-ables. Another source of death of an...
