This paper investigates dynamics of poverty in urban Ethiopia using both subjective and objective definitions of poverty. The two sets of estimates of persistence and recurrence of poverty are similar, suggesting that consumption-based mobility estimates are not seriously distorted by...

This paper focuses on the persistency of poverty in rural and urban households in Ethiopia by estimating dynamic probit models. Unobserved heterogeneity, first order state dependence and serially correlated error component are allowed for. The empirical results for both rural and urban areas...

A dynamic Tobit model is applied to longitudinal data to estimate the hours of work of married women in Sweden during 1992-2001. Hours of work are found to be negatively related to fertility. Other characteristics of married women are also found to have an effect on labor supply. Inter- temporal...

Welfare persistence is estimated in and compared between Swedish-born and foreignborn households. This is done within the framework of a time-stationary dynamic discrete choice model controlling for the initial condition and unobserved heterogeneity. Three different types of persistence are...

This paper analyzes the inter-temporal labor force participation behavior of married women in Sweden. A dynamic probit model is applied, controlling for endogenous initial condition and unobserved heterogeneity, using longitudinal data to allow for a rich dynamic structure. Significant...

Fifteen years of copy-editing experience – with theses (both in economics and in several medical fields), journal articles, book chapters and books, conference presentations, government reports, etc. – are distilled here. Papers are often sent to me for “language correction”, but what I...

Time heterogeneity, or the fact that subjects are measured at different times, occurs frequently in non-experimental situations. For time heterogeneous data having error components regression structure it is demonstrated that under customary normality assumptions there is no estimation method...

Providing health insurance involves a trade-off between the benefits from risk spreading and the costs due to moral hazard. Focusing on pharmaceuticals consumption, this paper examines theoretically whether reference pricing, requiring individuals to pay the price difference if, in this case,...

Should governments allow parallel trade of pharmaceuticals? There is no clear-cut answer to this question, since parallel trade causes some public concerns. One is that prices might not decrease much in the home country because consumers are price insensitive as a result of medical insurance....

Recently there has been a surge in interest on how HIV/AIDS affects fertility in countries hit by the disease. In this study, the effect of communal HIV/AIDS on fertility in rural Malawi is estimated using individual data from the 2004 Malawi Demographic and Health Survey on fertility and the...
