Finding an efficient method for sampling micro- and small-enterprises (MSEs) for research and statistical reporting purposes is a challenge in developing countries, where registries of MSEs are often nonexistent or outdated. This lack of a sampling frame creates an obstacle in finding a representative sample of MSEs. This study uses computer simulations to draw samples from a census of businesses and non-businesses in the Tshwane Municipality of South Africa, using three different sampling methods: the traditional probability sampling method, the compact segment sampling method, and the World Health Organization's Expanded Programme on Immunization (EPI) sampling method. Three mechanisms by which the methods could differ are tested, the proximity selection of respondents, the at-home selection of respondents, and the use of inaccurate probability weights. The results highlight the importance of revisits and accurate probability weights, but the lesser effect of proximity selection on the samples' statistical properties. 相似文献

Our analysis reveals that, from Russia's perspective, there is no economic rationale to unify the price of natural gas it sells domestically and in Europe. We argue that pipelines allow Gazprom to segment the Russian market from the European (including Turkey) market and that Russia has market power in the European market. If Russia were to fail to exploit this market power in its European market, by selling its natural gas to Europe at only full long‐run marginal cost plus transportation costs, Russia would lose between $5 billion and $7.5 billion per year (almost two per cent of its GDP). If, instead, Russia were to raise its domestic prices to the prices it charges in Europe, Russian industry would incur very large investment adjustment and unemployment costs in the short run – adjustment costs that cannot be justified on the basis of comparative advantage. We estimate that the efficient world price would be achieved if Gazprom were to employ its optimal ‘two‐part tariff’. The optimal two‐part tariff would double Gazprom's annual profits in Europe, but it involves significant long‐term risks for Gazprom of lost market share. 相似文献

The adaptive pressures facing humans and other animals to make decisions quickly can be met both by increasing internal information-processing
speed and by minimizing the amount of information to be used. Here we focus on the latter effect and ask how, and how well,
agents can make good decisions with a minimal amount of information, using two specific tasks as examples. When a choice must
be made between simultaneously-available options, minimal information in the form of binary recognition (whether or not each
item is recognized) can be used in the recognition heuristic to choose effectively. When options are encountered sequentially one at a time, minimal information as to whether or not
each option is the best encountered so far is sufficient to guide agents using a simple search-cutoff rule to high performance
along several choice criteria. Both of these examples have important economic as well as biological applications, and show
the power of simple fast and frugal heuristics to produce good decisions with little information.

Since 2003, the West and Central African (WCA) cotton initiative in the World Trade Organization has stood as an ambitious case of Africa's desire to be integrated into the trading system and yet also receive reparations for past injuries. This article seeks to explore how and why the initiative debuted through close attention to the interdependence between power and language in diplomatic practice. It takes the concept of cognitive framing to explore the relationship between political legitimacy and mobilisation capacities. The genesis of cotton as ‘an issue’ is critically examined, focusing on how the WCA countries constructed a novel ‘competitive victim’ frame to define themselves and the problem. While this opening move was effective, it also featured tensions that were exploited by Northern actors who were threatened by the campaign. I argue that what followed was the introduction of a politically driven ‘counterframe’, which divided the problem into a ‘trade-related’ component and a ‘development-related’ component. It is important to understand why and how this distinction was constructed and monitored. By scrutinising the relationship between framing and institutional power, I suggest that the counterframe won over the original frame, leading to a re-positioning of the demanders and a re-calibration of their expectations. 相似文献

Using what scholars have identified as the major explanations of industrial unrest in the United States, Lloyd measures changes in attitudes of students engaged in mock collective bargaining negotiations. By testing before and after the bargaining sessions, he is able to show the influence of role playing upon perception. 相似文献

This study used a multivariate regression analysis of industry-and firm-specific factors to determine characteristics that lead to manufacturing firms’ foreign direct investment in the United States (FDIUS). Two hundred forty firms were examined (137 investors and 103 noninvestors) from 7 countries in 10 industries during the 1984–1988 period. Firm size and overall profits were positive and significant indicators of FDIUS, but firms’ return on assets was not significant. Three industry-specific variables (prior exports to the United States, industry concentration, and technological intensity) were examined; they were generally positive but insignificant indicators of FDIUS. 相似文献

This article discusses consumption as a social process that is part of social provisioning and is in an evolutionary interplay with other social processes. The analysis provides grounds for a context-specific research that explores consumption in the context of a culture-nature life process, and draws on material from various disciplines. The article seeks to contribute to the literature on social provisioning as an organizing concept in heterodox economics. The first section explains what is meant by social process and delineates its elements. The second section formulates a categorization of social processes, and locates a consumption process within a system of culture-nature life processes. The rest of the article delineates the elements of the consumption process, providing illustrations based on literature from various disciplines. Specifically, the third section discusses consumption activities. The fourth section discusses institutions and systems of provision of goods and services. The fifth section applies the concept of habits of life and thought to the consumption process. Finally, the article concludes that the formulated analysis transcends dualisms such as social-economic, cultural-material, society-nature, and micro-macro, and draws implications for heterodox economics. 相似文献

The spectacular export performance of the East Asian NICs is clearly indicated by their increasing shares of manufactured exports in the world markets. However, the conventional wisdom that the comparative advantage of industrialized countries such as Japan has systematically shifted to the NICs is challenged by the results from this study. A detailed analysis of the threedigit SITC product categories for manufactures indicates that NIC exports have not replaced Japan's in the U.S. market. The growth of manufactured exports from the NICs is moving along with the growth of Japan's exports in similar product categories but at different stages of the product cycle or of technology sophistication. Hence, the NICs, rather than replacing the exports from Japan, are merely supplying some complementary manufactured products to the industrialized market. 相似文献
