This paper presents an analysis of the implications it has on standard growth models assume an alternative hypothesis to the exponential growth of the population and how modeling time can alter the dynamic behavior of these models. An extension (in continuous time and discrete time) of the...

A conflict of Ricardian type is arised. Landowners produce exportable salary-goods and consume imported luxury goods. Small industrialists produce non-tradable manufactures with sunk costs by importing capital goods. Employees consume exportable goods and non-tradable manufactures. Quantities...

The aim of the paper is to use the data envelopment analysis (DEA) for mining in Zacatecas and provide efficiency indicators in the years 1998, 2003, and 2008. We compare the performance of the state of Zacatecas with other mining states in Mexico. Then the empirical analysis extends to specific...

In this paper it is carried out a methodology based on Fuzzy Logic tech- niques for searching a solution which has been reached by consensus. This solution is related to labour reform and considers Trade Unions, Employers' Associations, and Government opinions. The proposed model belongs to the...

The main objective of this study is the identification of the explanatory factors on the differences in efficiency in the retail sector enterprises (CNAE-09 4711) in Spain, paying particular attention to the regulation in order to clarify the way in which this regulation has influenced the...

In this work, we propose an integer linear programming model for production scheduling of a group of finished products with independent demand. The model for the master production scheduling (MPS) is designed by considering production and inventory costs, as well as the productive process...

Performance measurement is an area of crucial interest in asset valuation and investment management. High volatility as well as time aggregation of returns, amongst other characteristics, may distort the results of conventional measures of performance. In this work, we study the performance of...

The main objective of this work has focused on extending the existing literature on the analysis of total factor productivity of the Health Care Centers (HCC) of the Community of Madrid (Spain) in the period 2015-2017, with two important contributions; the application and comparison of the...

The theory of restrictions (TOC) is a philosophy of continuous improvement, which focuses on the weakest link in the chain, to improve the performance of the production system. The purpose of the research was to determine the quantities to be made of each product and its production sequence in a...

Timetabling scheduling is classified as a combinatorial problem for which there are multiple solution alternatives, including the integer programming. However, the modeling of operational rules and the size of real problems makes its use not common compared to other techniques. This article...
