Policymakers have suggested the use of taxes to raise the relative cost of buying fast food. Yet, little is known of the structure of demand for food-away-from-home (FAFH) in general. This study provides estimates of the price-elasticity of demand for four different types of FAFH using a new...

В статье рассматриваются некоторые вопросы дискретного представления непрерывных управленческих процессов на основе мониторинга ключевых параметров внешней...

We study whether R&D subsidies can be used to encourage sustained R&D performance. To this end we measure the importance of true state dependence (TSD) in R&D performance and of subsidies’ inducement effects. Estimates that are based on a panel of Spanish manufacturing firms that are observed...

In surface growth simulations, usually the substrate is initially considered smooth with no roughness. But as known in reality, many substrates in nature are initially rough. In this article, we study the sensitivity of dynamic scaling of different models on rough substrates generated by...

This paper addresses statistical estimation problems of the optimal repair-cost limits minimizing the long-run average costs per unit time in discrete seting. Two discrete repair-cost limit replacement models with/without imperfect repair are considered. We derive the optimal repair-cost limits...
