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...

In this paper we consider the classical newsvendor model with profit maximization. When demand is fully observed in each period and follows either the Rayleigh or the exponential distribution, appropriate estimators for the optimal order quantity and the maximum expected profit are established...

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...

Three estimation policies for the optimal order quantity of the classical newsvendor model under exponential demand are evaluated in the current paper. According to the principle of the first estimation policy, the corresponding estimator is obtained replacing in the theoretical formula which...

In the classical newsvendor model, when demand is represented by the normal distribution singly truncated at point zero, the standard optimality condition does not hold. Particularly, we show that the probability not to have stock-out during the period is always greater than the critical...

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...

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,...
