Bilateral, product-level data exhibit a number of strong patterns that can be used to evaluate international trade theories, notably the spatial incidence of “export zeros” (correlated with distance and importer size), and of export unit values (positively related to distance). We show that leading theoretical trade models fail to explain at least some of these facts, and propose a variant of the Melitz model that can account for all the facts. In our model, high quality firms are the most competitive, with heterogeneous quality increasing with firms' heterogeneous cost. (JEL F11, F14, F40)

Comparative advantage is based on ‘locational factors’ so that trade leads to growth and its spatial concentration. Until recently, the nexus between trade and spatial growth received little space within trade analyses though it did not appear to be a missing link in initial contributions to trade theory. The reshaping of the global economy with greater integration has called for analyses of trade and spatial growth. This article examines theoretical premises of the link between international trade and spatial growth, and the implications of reshaping of the global economy for the study of spatial growth within trade theory.

Background. Dynamic changes in international economic relations and trade for thorough analysis and forecasting require an adequate paradigm of international trade theory, which would take into account not only economic and political factors of its development, but also the diverse civilizational context of the world community, which determines mental, social and cultural features of the development of a country. Problem research state. Problems of political economy in international trade to some extent affect the research of P. Krugman, M. Obstfeld, J. Frieden, E. Helpman, P. S. Afontsev, A. Mazaraki, T. Melnyk, V. Panchenko, N. Reznikova and others. But the structure of its methodological discourse and the subject of its research remain unclear. The aim of the articleis to clarify the political and economic discourse of the theory of international trade. Materials and methods. The materials of the research were the works of domestic and foreign specialists. In the process of preparing the article, general scientific research methods were used: historical, logical analysis, synthesis and abstraction. Results. Political economy is a normative manifestation of economic theory, which is formed under the influence of socio-economic and political concepts, the formed goals of social development. The subject of political economy of international trade – economic and socio-political relations that determine and accompany international trade and determine the goals and content of trade policy of its subjects. It is proposed to expand the mechanism of formation of relative advantages and trade policy of the country by including factors that determine not only its economic potential and specialization, but also the risks that may be caused by political decisions. It is argued that the problem of «protectionism vs liberalism» in international trade at the state level will always exist. It turns out that the problem of justice in international economic relations and trade is determined by the civilizational content of the development of countries, in which human capital plays a crucial role. Conclusion. The paradigm of political economy in international trade should be based on an expanded interpretation of relative benefits by assessing the impact of economic, social and political institutionson them, the peculiarities of national trade policies.
