Hausdorff Dimension of Average Conformal Hyperbolic Sets

The Hausdorff dimension of a conformal repeller or conformal hyperbolic set is well understood. For non-conformal maps, the Hausdorff dimension is only known in some special cases. Ban, Cao and Hu defined the concept of an average conformal repeller which generalises conformal, quasi-conformal and weakly conformal repellers, and they found an equation for the Hausdorff dimension for an average conformal repeller. In this paper we generalise this concept to average conformal hyperbolic sets, and obtain a similar equation for the Hausdorff dimension.Comment: 17 pages, 0 figure

The origins of American resource abundance

American manufacturing exports became increasingly resource-intensive over the very period, roughly 1880-1920, during which the U.S. ascended to the position of world leadership in manufacturing. This paper challenges the simplistic view that the resource-intensity of manufacturing reflected the country''s abundant geological endowment of mineral deposits. Instead, it shows that in the century following 1850 the U.S. exploited its natural resource potentials to a far greater extent than other countries and did so across virtually the entire range of industrial minerals. It argues that "natural resource abundance" was an endogenous. "socially constructed" condition that was not geologically pre-ordained. It examines the complex legal, institutional, technological and organizational adaptations that shaped the U.S. supply-responses to the expanding domestic and international industrial demands for minerals and mineral-products. It suggests that the existence of strong "positive feedbacks"--even in the exploitation of depletable resources--was responsible for the explosive growth of the American minerals economy.economic development an growth ;

GLOBALIZATION RELOADED: AN UNCTAD PERSPECTIVE

This paper rejects the characterization of globalization as an autonomous and irresistible process driven by the impersonal forces of the market and technical progress. Whether domestic or global, market forces are shaped and controlled by policy choices and the institutional frameworks in which they are made. In the absence of adequate institutional frameworks and productive capacities, rapid liberalization is as likely to lead to stagnation and unemployment as to growth and rising incomes per head. We show that the major economic forces presumed to be crucial for spreading the benefits of globalization have been less global than often presented, have proved to be much weaker than widely predicted and carry potentially damaging effects as well as benefits. Accordingly, and without denying that by the late 1970s many developing countries needed to find new ways of inserting themselves into the international economy, we argue that the new policy orientation of macroeconomic stringency, downsizing the public sector and the rapid opening of developing country markets to foreign trade and capital after the debt crisis, has failed to produce an economic environment that supports faster economic growth and strengthens productivity performance. In suggesting the outlines of a more strategic approach to economic development the emphasis is on the need for domestic investment to be mobilized as the basis for industrialization and for a gradual approach to integration with the global economy.

GLOBALIZATION MYTHS: SOME HISTORICAL REFLECTIONS ON INTEGRATION, INDUSTRIALIZATION AND GROWTH IN THE WORLD ECONOMY

It has become popular to draw a parallel between current globalization trends and the half century of international economic integration before the First World War. Indeed, some writers suggest that current trends mark a return to this earlier period, from which they draw strong conclusions about growth prospects and convergence associated with globalization. This paper assesses this historical parallel. It accepts that many features of today´s international economy are not unique. However, it is sceptical of efforts to make a direct parallel with the earlier period. In particular, the paper shows that the period before 1913 was not one of trade liberalization, nor one of reduced expectations about the role of the State, and suggests that rapid industrial growth in some economies cannot be explained by globalization pressures. More generally, a description of this earlier period of globalization as one of rapid growth and convergence is questioned, and instead associated with uneven economic development, during which a very small group of countries were able to reinforce their domestic growth efforts through links to the international economy, while for others these same links did little to alter long-term growth prospects, and in some cases even hindered them.
