Over more than two centuries the development ofeconomic theory has
created a wide array of different concepts, theories, and insights. My
recent book Capital and Knowledge (Zhang, 1999a) shows how separate
economic theories such as the Marxian economics, the Keynesian
economics, the general equilibrium theory, and the neoclassical growth
theory can be examined within a single theoretical framework. The
Capital and Knowledge constructs an economic theory to account for the
phenomena explained by the main economic theories (of national
economies) in a unified manner. It tries to draw together the disparate
branches of economics into a single organized system ofknowledge. This
book is a part of my economic theory with endogenous population,
capital, knowledge, preferences, sexual division of labor and
consumption, institutions, economic structures and exchange values over
time and space (Zhang, 1996a). As an extension of the Capital and
Knowledge, which is focused on the dynamics of national economies, this
book is to construct a theory of international trade. We are concerned
with dynamic relations between international division of labor, division
of consumption and determination of prices structure in global economy.
We examine dynamic interdependence between capital accumulation,
knowledge creation and utilization, economic growth, price structures
and international trade patterns under free competition. Our theory is
constructed on the basis of a few concepts within a compact framework.
