This article adds technology choice to a free-entry Cournot model with linear demand and constant marginal costs. Firms can choose from a discrete set of technologies. This simple framework yields non-existence of equilibrium, existence of multiple equilibria and equilibria in which ex-ante identical ̄rms choose di®erent technologies as possible outcomes. I provide a full characterization of th...

Based on a structural vector autoregressive framework the monthly data from April 1997 to July 2016, this study is an attempt show impact of crude oil price rate inflation and economic growth in India. The results showed that has positive whereas inverse relation exists between growth. Further, we segregated into two components, is, negative partial sum through nonlinear asymmetric distribution...

Data for discrete ordered random variables are often characterised by “excessive” zero observations. Traditional ordered probit models have limited capacity in explaining the preponderance of zero observations, especially when the zeros may relate to two distinct situations of non-participation and infrequent participation (or consumption), for example. We propose a zero-inflated ordered probit...

Agricultural research drives increases in agricultural productivity, and the number of private agricultural input firms has been declining. The empirical relationship between the number of firms doing applied biotechnology crop research and the amount of research output they produce is investigated in a research profit function model. Increases in seed industry concentration have reduced biotec...

This research aims to analyze and to compare the ability of different mathematical models, such as artificial neural networks (ANN) and ARCH and GARCH models, to forecast the daily exchange rates Euro/U.S. dollar (USD), identifying which, among all the models applied, produces more accurate forecasts. By empirically comparing the different mathematical models developed in this research, the tra...

We consider theoretically and empirically the allocation of time and money within the household. The novelty of our empirical work is that we have a survey which provides information on both time use and the allocation of some goods within the household, for the same households. Thus we can consider whether a partner who enjoys more leisure also receives more consumption, which looks like the o...
