Using administrative records data from Spanish Social Security, we analyse the pattern and the determinants of individual unemployment benefit spell durations. We compare a period of expansion (2005-2007) and the recent recession (2009-2011), allowing us to determine the impact of the...

We analyze mobility in urban Mexico between three labor market states: working in the formal sector, working in the informal sector, and not working. We use a dynamic multinomial logit panel data model with random effects, explaining the labor market state of each individual during each time...

This paper presents results from an experimental manipulation of one versus multiple-items per screen format in a Web survey.The purpose of the experiment was to find out if a questionnaire s format influences how respondents provide answers in online questionnaires and if this is depending on...

In this paper we propose a bivariate model for the trading intensities of stocks in a particular industry.The model consists of a univariate duration model for trades in either of the stocks and a probit-specification for which of the two stocks is traded.We apply the model to the trading...

We analyze answers to household survey questions on whether the respondents' household income has changed in the past twelve months, and on whether the respondents expect their household income to change in the next twelve months. Both questions are answered on a discrete five points scale.The...

Using longitudinal data of the Health and Demographic Surveillance System (HDSS) in Matlab, Bangladesh, covering the time period 1982 – 2005, and exploiting dynamic panel data models, we analyze siblings’ death at infancy, controlling for unobserved heterogeneity and a causal effect of death...

Response variables that are scored as counts and that present a large number of zeros often arise in quantitative health care analysis. We define a zero-in flated Poisson model with fixed-effects in both of its equations to identify respondent and health-related characteristics associated with...

This paper develops a theoretical model of optimal effort in consumer choice.The model extends previous consumer choice models in that the consumer not only chooses a product, but also decides how much effort to apply to a given choice problem.The model yields a unique optimal level of effort,...

We use panel data from the German Socio Economic Panel to estimate the determinants of language fluency of immigrants, and its impact on earnings. Self reported measures of language proficiency contain substantial reporting errors. We specify a panel data model which takes explicitly account of...
