Terms of use: Documents in ABSTRACTWe rank 5,107 products and 124 countries according to the Hidalgo and Hausmann (2009) measures of complexity. We find that: (1) the most complex products are in machinery, chemicals, and metals, while the least complex products are raw materials and commodities, wood, textiles, and agricultural products; (2) the most complex economies in the world are Japan, Germany, and Sweden, and the least complex, Cambodia, Papua New Guinea, and Nigeria; (3) the major exporters of the more complex products are the high-income countries, while the major exporters of the less complex products are the low-income countries; and (4) export shares of the more complex products increase with income, while export shares of the less complex products decrease with income. Finally, we relate the measure of product complexity with the concept of Complex Products and Systems, and find a high degree of conformity between them.
This article surveys the recent empirical literature on total factor productivity (TFP) growth in East Asia, and the debate about the sources of growth in the region. It is concluded that: (i) the main merit of this literature is that it has helped focus the attention of scholars on the growth process of East Asia; (ii) the theoretical problems underlying the notion of TFP are so significant that the whole concept should be seriously questioned; (Hi) the TFP growth estimates for the region vary significantly, even for the same country and time period; and (iv) research on growth in East Asia based on the estimation of TFP growth is an activity subject to decreasing returns. If we are to advance in understanding how East Asia grew during the last 30 years we need new avenues of research.
There is no subject so old that something new cannot be said about it. Glendower: I can call spirits from the vasty deep Hotspur: Why, so can I, or so can any man; But will they come when you do call for them? This paper surveys the theoretical literature on aggregation of production functions. The objective is to make neoclassical economists aware of the insurmountable aggregation problems and their implications. We refer to both the Cambridge capital controversies and the aggregation conditions. The most salient results are summarized, and the problems that economists should be aware of from incorrect aggregation are discussed. The most important conclusion is that the conditions under which a well‐behaved aggregate production function can be derived from micro production functions are so stringent that it is difficult to believe that actual economies satisfy them. Therefore, aggregate production functions do not have a sound theoretical foundation. For practical purposes this means that while generating GDP, for example, as the sum of the components of aggregate demand (or through the production or income sides of the economy) is correct, thinking of GDP as GDP=F(K, L), where K and L are aggregates of capital and labor, respectively, and F(•) is a well‐defined neoclassical function, is most likely incorrect. Likewise, thinking of aggregate investment as a well‐defined addition to ‘capital’ in production is also a mistake. The paper evaluates the standard reasons given by economists for continuing to use aggregate production functions in theoretical and applied work, and concludes that none of them provides a valid argument.
