This paper replicates two spatial monopoly models by Takayama and Judge. The first one is a simple spatial monopoly model. The second model allows the activity of arbitrage between any pains of consumption regions if the price differential exceeds the corresponding unit transportation cost. With...

This paper improves upon the existing literature surrounding the production order quantity inventory model in which unit cost and daily production are assumed to be constant. By including economies of scale into the model, we examine its impact on production order quantity and total cost. The...

The combinatorial nature of integer programming is inevitable even after takingspecific model structure into consideration. This is the root problem in implementing large-scale nonlinear integer programming models regardless of which algorithm one chooses to use. Consequently, we suggest that...

This paper uses the panel data of energy consumption and GDP for 82 countries from 1972 to 2002. Based on the income levels defined by the World Bank, the data are divided into four categories: low income group, lower middle income group, upper middle income group, and high income group. We...

This paper estimates the demand for cigarettes using panel data – 42 states and Washington, D.C. – from 1961 to 2002. We first employ the panel unit root test before estimating the demand structure. We have found that (i) the price and income elasticities are approximately –0.41 and 0.06,...

This paper applies recently developed unit root and cointegration models to determine the appropriate Granger causality relations between stock prices and exchange rates using recent Asian flu data. Coupled with impulse response functions, it is found that data from Japan and Thailand are in...

In this paper, we investigate the relationship between the demand ad valorem, cost ad valorem and unit taxes in terms of price, quantity and tax revenue. In particular, we prove that the Musgravian transformation holds in the Hotelling model. In addition, we show that the Suits‐Musgrave...
