This paper demonstrates optimal policies for capacitated serial multiechelon production/inventory systems. Extending the Clark and Scarf (1960) model to include installations with production capacity limits, we demonstrate that a modified echelon base-stock policy is optimal in a two-stage...

The authors propose a new method for estimating the power-law exponents of firm size variables. Their focus is on how to empirically identify a range in which a firm size variable follows a power-law distribution. On the one hand, as is well known a firm size variable follows a power-law...

The formation of the European Union (EU) is the one of the biggest political – economic events of the last 50 years. The aim of this study is to develop EU economy functioning system dynamic model. Main research method is system dynamics. General scheme of EU economy system dynamic model is...

We propose a new method for estimating the power-law exponent of a firm size variable, such as annual sales. Our focus is on how to empirically identify a range in which a firm size variable follows a power-law distribution. As is well known, a firm size variable follows a power-law distribution...

This paper analyzes the effect of time aggregation on estimates of the elasticities of output with respect to employment and to average hours of work. The main goal is to get accurate estimates of production function parameters. Low frequency data generate better estimates of output- employment...

Once the global leader in telecommunication systems and the Internet, over the past two decades the United States has fallen behind global competitors, and in particular China, in mobile-communication infrastructure—specifically 5G and Internet of Things (IoT). This national failure, with the...

This study is an attempt to analyze the imp act of Edible Oil Deficit on Food Expenditure in Pakistan for the period 1971-2008. Edible oil deficit is one of the major concerns for the policy-makers in Pakistan. Despite of having agriculture based economy; Pakistan is unable to fulfil her...

This study is an attempt to analyze the impact of Edible Oil Deficit on Food Expenditure in Pakistan for the period 1971-2008. Edible oil deficit is one of the major concerns for the policy makers in Pakistan. Despite of having agriculture based economy; Pakistan is unable to fulfil her domestic...

How relevant is the notion of evolution for economics? In view of the paradigmatic influence of Darwinian thought, several recently advocated interpretations are discussed first which rely on Darwinian concepts. As an alternative, a notion of evolution is suggested that is based on a few,...
