Increasing energy efficiency and exploiting energy saving potential are two important practices that can help to ensure future energy security in China. This paper proposes a new total factor energy efficiency indicator, based on the directional meta-frontier data envelopment analysis (DEA) approach, to account for the heterogeneity of production technology among provinces in China. This indica...

Although the lot size problem (i.e., the economic order quantity model) has been widely accepted and used by researchers and practitioners, it has also been criticized by others on the grounds that not accounting for some of the hidden costs in inventory systems often lead to poor results. This paper postulates that estimating these hidden costs may be attained by applying the first and second ...

In this paper, the nominal wage equation of a Core-Periphery model of New Economic Geography is derived. In order to show empirical evidence of the resulting hypothesis, the nominal wage equation is estimated for the Spanish provinces in the year 2003. Our results illustrate that the market access variable is statistically significant and quantitatively important in the explanation of the spati...

This paper explores policy applications of ‘new institutional economics’ theory in relation to markets and economic development. It argues for application of an analytical framework which instead of looking at institutions primarily in terms of their contributions to making competitive markets work better, sees such markets as one form of institution fulfilling exchange and coordination functio...

Within the economic order quantity (EOQ) framework, the main purpose of this paper is to investigate the retailer’s optimal replenishment policy under permissible delay in payments. All previously published articles dealing with optimal order quantity with permissible delay in payments assumed that the supplier only offers the retailer fully permissible delay in payments if the retailer ordered...

Using a world trade model with India subdivided into states, the paper examines how regional disparities are affected by domestic inter-state trade as well as international trade. According to the analysis, international liberalisation promotes decentralisation and convergence, not divergence, so trade is not to blame for India’s growing regional disparities. High economic growth within India m...

the present research proposes and optimizes the performance of a novel solar-driven combined cooling, heating, and power (cchp) kalina system for two seasons—winter and summer—based on exergy, exergo-economic, and exergo-environmental concepts applying a non-dominated sort genetic algorithm-ii (nsga-ii) technique. three criteria, i.e. daily exergy efficiency, total product cost rate, and total ...

our aim was to make right and informative decision about choosing the most cost-effectiveness heterogeneous infectious waste treatment methods and devices.in this descriptive study, decision tree analysis, with 10-yr time horizon in bottom-up approach was used to estimate the costs and effectiveness criteria of the employed devices at provider perspective in iranian hospitals. we used the one-w...

In general, a supplier/retailer frequently offer trade credit to stimulate their respective sales. The main purpose of this paper is to investigate the optimal supplier/retailer’s replenishment decisions under two levels of trade credit policy within the economic order quantity (EOQ) framework. This paper deals with the supplier/retailer’s inventory replenishment problem under two levels of tra...
