This paper examines the impact of government spending on the environment using a panel of 77 countries for the time period 1980-2000. We estimate both the direct effect of government spending on pollution and the indirect effect which operates through government spending impact on per capita...

Cultural and epistemic backgrounds, subject-object relationships, assumptions and conflicts, are examined by heuristic-hermeneutic processes in the sociocultural learning niches. Diagnosis and prognosis of current problems take into account the connections (assets) and ruptures (deficits)...

Diagnosis and prognosis of current problems take into account the connections (assets) and ruptures (deficits) between the different dimensions of being-in-the-world, mutually entangled as donors and recipients: intimate; interactive; social and biophysical. Guidance and counselling consider the...

This paper considers the classical newsvendor model when demand is normally distributed but with a large coefficient of variation. This leads to observe with a non-negligible probability negative values that do not make sense. To avoid the occurrence of such negative values, first, we derive...

This paper considers the classical newsvendor model when, (a) demand is autocorrelated, (b) the parameters of the marginal distribution of demand are unknown, and (c) historical data for demand are available for a sample of successive periods. An estimator for the optimal order quantity is...

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 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,...
