This paper examines trends in the instability of personal incomes in Britain in terms of changes in the transitory variance and in volatility, measures that have received much recent attention in research about the USA. It is shown that, although US measures have trended upwards over the past...

Using data from the German Socio-Economic Panel (GSOEP), this paper analyzes the dynamics of equivalent income in Germany in the eighties and nineties. Special emphasis is given to the separation of permanent and transitory components, the persistence of transitory shocks and their implications...

This paper is about the distributional dynamics of net household income in Germany, the US and the UK. We reject the common wisdom that Germany is a country in statsis: stable cross-sectional distributions are deceptive, concealing substantial movements beneath the surface. The US and the UK...

Many questions in social research must be evaluated over time. For example, in studies of intragenerational mobility, measuring opportunity for economic advancement requires longitudinal data. The authors develop and use a class of hybrid functional models to demonstrate how different models can...

The need to estimate structured covariance matrices arises in a variety of applications and the problem is widely studied in statistics. A new method is proposed for regularizing the covariance structure of a given covariance matrix whose underlying structure has been blurred by random noise,...

The constraint that a covariance matrix must be positive definite presents difficulties for modeling its structure. Pourahmadi (1999, 2000) [18,19] proposed a parameterization of the covariance matrix for univariate longitudinal data in which the parameters are unconstrained, which is based on...

This paper is about the distributional dynamics of net household income in Germany, the US and the UK. We reject the common wisdom that Germany is a country in statsis: stable cross-sectional distributions are deceptive, concealing substantial movements beneath the surface. The US and the UK...

In this simulation study, I compare the efficiency and finite sample bias of parameter estimators for popular income dynamic models using various forms of autocovariances. The dynamic models have a random walk or a heterogeneous growth permanent component, a persistent autoregressive component...

Discriminant analysis (DA) procedures based on parsimonious mean and/or covariance structures have recently been proposed for repeated measures data. However, these procedures rest on the assumption of a multivariate normal distribution. This study examines repeated measures DA (RMDA) procedures...
