Migration, Unemployment and Trade focuses on the issues of migration, welfare and unemployment in a trade and development framework. Several chapters of the book analyze the implications of internal labor mobility in a model designed to highlight its implications for regional welfare, urban unemployment, rural-urban dichotomy and structural adjustment. An important innovation in this work is the disaggregation of the economy and the use of separate utility functions to highlight non-homogeneity of preferences. The book also deals with international mobility of factors in different frameworks. In particular it concentrates on the highly emotive issue of legal and illegal migration. Thus this work incorporates interesting and important features of labor economics and factor mobility into trade and distortion theory.

This volume incorporates important surveys from a historical perspective. The masterly survey of Bhagwati provides great intuition about trade theoretical results and Chipman's three surveys present the mathematics of trade theory. These are very deep surveys from a mathematical point of view and show, for example, the Ricardian model as an application of Quasi-Concave programming and also the magnificent use of Sperner's Lemma for the odd and even intersections that occur in some problems in trade theory. There are also other surveys bringing the literature up to date and covering specific topics in trade theory.

Tourism is a growing and important industry in both developed and developing countries. In many countries it is an important source of foreign exchange. Moreover, it employs a large proportion of the domestic labour force as well as guest workers and illegal migrants. In spite of its importance as an exportable good, tourism has not been integrated into the real theory of trade. This book represents a pioneering attempt at integrating tourism into the pure theory of international trade. Some of the related issues discussed include illegal migrants, guest workers and long-run economic growth.

While many fields of our current life and technology make use of the involvement of chemistry, even in a subtle way as quantum-, mathematical-, physical-, nano-, bio-, or eco-, and chemical disciplines, the chemistry itself drives almost all nature cycles through the atomic and molecular structure and reactivity universal principles. This book presents an interdisciplinary-internationally picture of chemical information embedded in various micro- and macro- systems in order to show how fertile the field of research and knowledge is thanks to chemistry.

These notes are based on the microeconomics lectures delivered in the Master of Science in Applied Economics (MSAE) programme at the City University of Hong Kong. They have been delivered in the fall Semesters of 2005- 2007. The lectures are delivered over a period of thirteen weeks (three hours per week). One should always remember the time constraint involved in delivering lectures. Everything can not be covered; therefore one has to be selective in what is taught. This is the reason for calling these lectures core microeconomics. The topics selected and taught reflect our perceptions and value judgement about core topics in microeconomics. Also the students in this class at the City University of Hong Kong come from a very heterogeneous background which varies a lot; medicine, law, mathematics, engineering, physics, biology, and of course economics. The course is designed to teach all these heterogeneous students important topics in microeconomics in a span of thirteen weeks. This is a tough task and many of these students are very ambitious and desirous of doing graduate studies in Europe, Canada, and the US. The feedback on this course has been extremely good from students who are pursuing graduate studies in Britain and the US. These are lecture notes that vary in level at which different topics are taught and also the depth at which these topics are covered. They should not be taken as a substitute for a textbook but as an aid for reading other textbooks.
