Finite mixtures of Skew distributions have become increasingly popular in the last few years as a flexible tool for handling data displaying several different characteristics such as multimodality, asymmetry and fat-tails. Examples of such data can be found in financial and actuarial...

In this paper we estimate the business telecommunications demands for local,intra-LATA and inter-LATA services, using US data from a Bill Harvesting (R) survey carried out during 1997. We model heterogeneity, which is present among firms due to a variety of different business telecommunication...

Parametric mixture models are commonly used in applied work, especially empirical economics, where these models are often employed to learn for example about the proportions of various types in a given population. This paper examines the inference question on the proportions (mixing probability)...

This paper takes a finite mixture approach to model heterogeneity in incentive and selection effects of drug coverage on total drug expenditure among the Medicare elderly US population. Evidence is found that the positive drug expenditures of the elderly population can be decomposed into two...

To match the stylized facts of high frequency financial time series precisely and parsimoniously, this paper presents a finite mixture of conditional exponential power distributions where each component exhibits asymmetric conditional heteroskedasticity. We provide stationarity conditions and...

This paper expands the standard analysis of female labor supply to permit preference heterogeneity by using a finite mixture model. Using the extended model, we obtain theory consistent results whereas a traditional model produces a negative substitution effect. We use our model to illustrate...

Kenya is predominantly a nature-based tourism destination with wildlife (concentrated in the southern part of the country) and beaches (along the Indian Ocean) accounting for over 85% of the international tourists visiting the country. Other attractions are based on the physical landscape of the...
