This study examines the significance of risk modelling and asymmetries when researchers test the popular economic theories concerning the term structure of interest rates. A panel data set of returns on government bond portfolios was used and methods to account for related movements in risk...

Given the random walk model, we show, for the traditional unrestricted regression used in testing stationarity, that no matter what the initial value of the random walk is or its drift or its error standard deviation, the sampling distributions of certain statistics remain unchanged. Using Monte...

Economic theory suggests that development is enhanced through income growth, which is driven through increased trade. However, the empirical evidence of such a relationship most of the times is proved to be weak. In this study we try to determine the factors influencing this relationship by...

This study, using a certain simulation strategy, for the exact maximum likelihood estimator of θ from the MA(1), estimates appropriate percentiles, together with their standard errors, offering a new set of critical values for testing in finite samples H0: θ = -1, against H1: θ-1. In this...

This paper uses a dynamic panel data for 23 OECD and 50 non-OECD countries for the time period 1960-1990 in order to estimate the relationship between economic development (in the form of GDP) and environmental pollution (in the form of sulphur emissions)

This paper explores the relationship between economic development (in the form of GDP/c) and environmental pollution (in the form of sulphur emissions) by using a dynamic panel data for 97 countries for the time period 1950-2003. Various panel data econometric techniques are applied to a sample...

In this paper, one of the basic assumptions is that the environment provides two different kinds of services. First, the environment may serve as an input to the production of conventional goods. For example, the exploitation of an oil source from which one firm extracts the oil which in turn is...

This paper is concerned with the classic topic of intertemporal resource economics: the optimal harvesting of renewable natural resources over time by one and several resource owners with conflicting interests. The traditional management model, dating back to Plourde (1970), is extended towards...

This study presents a mathematical model for determining cost-effective emissions' control strategies in Europe, by minimizing sulphur abatement costs subject to different pollution control targets. The purpose is to compare the efficiency of a uniform percentage emissions reduction with a...

Purpose – This study aims to investigate the effects of stress and job satisfaction on the functioning of a company. It seeks to focus on factors affecting stress and job satisfaction such as number of work hours, good relations between management and employees, good function of the group and...
