An important issue in the agricultural actuarial literature is the extent to which sample period selection affects the accuracy of insurance rating. A conditional Weibull distribution approach is developed which explicitly models the interaction of weather, technology, and other variables...

We use a two-stage, sample selection model to investigate organic milk purchases using Neilsen’s Homescan data. In the first stage, households decide on a weekly basis to buy mainly organic milk or non-organic milk. Results from this stage show that higher income, better education, having...

Research on the presence of consumer racial discrimination in the baseball labor and memorabilia markets has produced contradictory empirical results. While studies of baseball salaries-find no evidence of discrimination, Nardinelli and Simon (1990) and Andersen and La Croix (1991) use data from...

Este trabajo desarrolla un método flexible y semiestructural para cuantificar empíricamente la transmisión no lineal de los shocks de renta a las decisiones de elección de cartera de los hogares, tanto en el margen extensivo como en el intensivo. Modelizo la participación en el mercado de...

We adapt the Expectation-Maximization (EM) algorithm to incorporate unobserved hetero- geneity into conditional choice probability (CCP) estimators of dynamic discrete choice problems. The unobserved heterogeneity can be time-invariant, fully transitory, or follow a Markov chain. By exploiting...

In this paper, we suggest a Stata routine for multinomial logit models with unobserved heterogeneity using maximum simulated likelihood based on Halton sequences. The purpose of this paper is twofold. First, we describe the technical implementation of the estimation routine and discuss its...

This paper investigates preference heterogeneity of wine consumers by using latent class models based onattitudinal questions. Such responses turn out to be an important source of additional information when the goalis to identify different groups of people with a similar wine preference...

In dynamic discrete choice analysis, controlling for unobserved heterogeneity is an important issue, and finite mixture models provide flexible ways to account for unobserved heterogeneity. This paper studies nonparametric identifiability of type probabilities and type-specific component...

We examine the failure determinants for large quoted UK industrials using a panel data setcomprising 539 firms observed over the period 1988-93. The empirical design employs datafrom company accounts and is based on Chamberlain’s conditional binomial logit model,which allows for unobservable,...
