This paper uses high-frequency data to examine the relation between official and free-market exchange rates in Albania. We use daily data to test econometrically, first, whether the official and free markets are efficient, in the sense that one cannot use exchange rate movements denominated in...

We propose a novel observation-driven dynamic finite mixture model for the study of banking data. The model accommodates time-varying component means and covariance matrices, normal and Student's $t$ distributed mixtures, and economic determinants of time-varying parameters. Monte Carlo...

Frequently in experiments there is not only variance in the reaction of participants to treatment. The heterogeneity is patterned: discernible types of participants react differently. In principle, a finite mixture model is well suited to simultaneously estimate the probability that a given...

The Short-Time Compensation (STC) program enables US firms to reduce work hours via pro-rated Unemployment Insurance (UI) benefits, rather than relying on layoffs as a cost-cutting tool. Despite the program's potential to preclude skill loss and rehiring/ retraining costs, firms' participation...

Diagnosing foehn winds from weather station data downwind of topographic obstacles requires distinguishing them from other downslope winds, particularly nocturnal ones driven by radiative cooling. We present an automatic classification scheme to obtain reproducible results that include...

This paper proposes a finite mixture model (FMM) to model the behavioral transition of calorie consumption with an assumption that nutrition consumption is a mixture of two different behavioral stages: a poor stage and an affluent stage. Based on 387 calorie-income elasticities collected from 90...
