Recent studies provide evidence that investors participating in the financial markets, decide for their actions using heuristics, according to their feelings and reacting to noise. In this paper, we extract two factors related to the variability of Premium/Discount (P/D): a behavioral and a...

In this study a brief description of the policy options for the control of public enterprise under different market structures is presented. A critical examination of the drawbacks of some similar studies in the international literature is also endeavored. Moreover, using a number of suggested...

One climate related phenomenon could affect many more. The direct costs associated to climate related factors pass to a number of other climate related costs through the indirect economic consequences of climate change. In this paper we propose a mathematical model which aims to provide...

This paper examines the effect of economic growth and government spending on the environment using a panel of 71 countries for the time period 1970-2008. In particular, we test the hypothesis of the existence of an inverted U-shaped relationship between economic performance and pollution, as...

In the current paper we study a real life inventory problem whose operating conditions match to the principles of the classical newsvendor model. Applying appropriate tests to the available sample of historical demand data, we get the sufficient statistical evidences to support that daily demand...

This paper presents results concerning the nonlinear analysis of the mean annual value temperature time series corresponding to the Earth’s global climate for the time period of 713 – 2004. The nonlinear analysis consists of the application of several filtering methods, the estimation of...

This paper examines the effect of economic policy on air quality using US quarterly data from 1973 to 2013. In particular, we analyze the short-run as well as the long-run interactions between fiscal and monetary policy with CO2 emissions, employing time series techniques of co-integration,...

In this paper, the optimal pollution level is identified under the assumptions of linear, quadratic and exponential cost functions. The corresponding optimal level of environmental policy is evaluated, with analytical forms in the linear and quadratic case, while in the exponential case, these...

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...
