today export diversification has become one of the most important economic objectives of development strategies in the developing countries. for various reasons, such as preventing instability in export prices of primary products in global markets, reducing fluctuations in exchanges of them compared with industrial goods, producing dynamic benefits resulted from exporting various goods and incr...

In this work, we present an improved global logic-based outer approximation method (GLBOA) for the solution of nonconvex generalized disjunctive programs (GDP). The GLBOA allows the solution of nonconvex GDP models, and is particularly useful for optimizing the synthesis of process networks. Two enhancements to the basic GLBOA are presented. The first enhancement seeks to obtain feasible soluti...

We employ the UTIP data set on the evolution of earnings inequality in manufacturing in the global economy to illuminate two questions. First, do regional patterns of similarity in the movement of large macroeconomic aggregates, such as real GDP, imply underlying similarities of industrial structure, so that knowledge of one national economy in a GDP cluster can reasonably be assumed to convey ...

Machine learning is the core of artificial intelligence. It is a fundamental way to the computer intelligence. Support vector machine is one of the important methods in the field of machine learning. It has the advantages of global optimization and strong generalization ability. It has been successfully applied to face recognition, fault diagnosis, financial forecasting and other fields. In thi...

This paper uses a variant of the IMF’s Global Economy Model (GEM) to illustrate how the macroeconomic impact on the United States of the rise in energy prices since the end of 2003 may vary depending on the source of the energy market imbalance. If oil market supply-side factors are driving prices higher, GDP will be permanently lower than it otherwise would be. However, if higher energy prices...

New Zealand entered a period of economic recession in early 2008, intensified by the global economic crisis of September 2008. Gross domestic product (GDP) fell consistently during 2008, and that year saw the economy’s worst performance in over a decade (The Treasury, 2010a). Real per capita GDP contracted through 2009 and, despite some market optimism in early 2010, economic indicators remain ...
