The paper examines the impact of the income distribution in a less-developed country (LDC) on its patterns of trade, through its influence on home market demand patterns. In a learning-by-doing model with nonhomothetic preferences, the authors show that import substitution under low inequality generates more focused learning and enhances trade potential more effectively. In addition, relative w...

A lack of written sources is a serious obstacle in the reconstruction of the medieval trade of art and art materials, and in the identification of artists, workshop locations, and trade routes. We use the isotopes of sulfur, oxygen, and strontium (S, O, Sr) present in gypsum alabaster to unambiguously link ancient European source quarries and areas to alabaster artworks produced over five centu...

Recent models of international trade have identified product quality as an important determinant of bilateral trade flows. Yet relatively little is understood about the relationship between the characteristics of the export market and the quality of products. In this paper we examine this link using Chinese data. We find evidence that product unit values vary with standard gravity variables in ...

The practical realization of beam steering mechanisms in millimeter wave communications has a large impact on performance. The key challenge is to find a pragmatic trade-off between throughput performance and the overhead of periodic beam sweeping required to improve link quality in case of transient link blockage. This is particularly critical in commercial off-the-shelf devices, which require...

In order to give immediate response the demand for qualified personnel production, services and local development in Cuba, continuity of higher studies, students at intermediate level can opt short cycle programs, which training process has an important component link with professional practice, therefore, objective work is expose authors' criterion conception labor practice Higher Level Traini...

We present a framework to study control systems with feedback loops closed over wireless communication links. We show the choice of communication parameters can greatly affect the performance of such systems. The trade-offs of data rate, time delay and packet loss in the communication link layer design are illustrated with a numerical example of an inverted pendulum. Packet loss is shown to sig...

There has been a gradual change and paradigm shift in the multilateral trade sphere regarding links between trade, sustainable development environment. Sustainable environment is no longer outside realm of WTO. The preamble tothe Agreement Establishing WTO expanded to include specific commitment development. approach seeks balance economic environmental protection concerns. This notable particu...
