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reporting purposes is a challenge in developing countries, where registries of MSEs are often nonexistent or outdated.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

In the Aftermath: Consumer Choice and the Deregulation of Australian Retail Banking, 1988–1993 下载免费PDF全文
This article explores whether deregulation of the Australian retail banking sector in the 1980s delivered the enhanced consumer choice that had been promised. Using new data on banking products and their usage, it analyses consumers' ability to select optimal ‘frontier’ products. It concludes that following deregulation of retail banking, product offerings underwent such tumultuous change that the scope for effective consumer choice was severely constrained. While there were improvements towards the end of the period, progress was not assisted by the banks' strategy of proliferating and re‐bundling products. Consequently, the anticipated improvements to consumer choice were slow to arrive. 相似文献

The pronounced increase in external imbalances in the European Economic and Monetary Union (EMU) during the years running up to 2008 is traditionally explained by financial integration through the common currency. This paper examines in a one-good, two-country overlapping generations’ model, with production, capital accumulation and public debt, the effects of financial integration on the net foreign asset positions of initially low-interest and high-interest rate EMU countries. We find that a lower savings rate and government expenditure quota, together with a higher capital production share in the latter can in fact be transformed into the observed external imbalances when interest rates converge. 相似文献

Through an examination of twenty Japanese owned manufacturing plants in China, this article seeks to question the usefulness of identifying Japanese competitive success as being associated with specific Japanese production management techniques. Rather Japanese plants adopt, seemingly profitably, various and differentiated production methods, depending on local and parent company circumstances. 相似文献

Small area estimation (SAE) entails estimating characteristics of interest for domains, often geographical areas, in which there may be few or no samples available. SAE has a long history and a wide variety of methods have been suggested, from a bewildering range of philosophical standpoints. We describe design-based and model-based approaches and models that are specified at the area level and at the unit level, focusing on health applications and fully Bayesian spatial models. The use of auxiliary information is a key ingredient for successful inference when response data are sparse, and we discuss a number of approaches that allow the inclusion of covariate data. SAE for HIV prevalence, using data collected from a Demographic Health Survey in Malawi in 2015–2016, is used to illustrate a number of techniques. The potential use of SAE techniques for outcomes related to coronavirus disease 2019 is discussed. 相似文献

ABSTRACT We explore the link between third-party certification (venture capital backing, analyst following and having a top underwriter), and post-IPO acquisition activity through the reduction in valuation uncertainty channel. In a sample of 2,424 U.S. IPOs, we find that third-party certification facilitates post-IPO acquisitions. The certified firms are both more likely and conduct acquisitions sooner after the IPO. Our results support the notion that third-party certification reduces post-IPO valuation uncertainty and thereby facilitates a more efficient acquisition strategy. 相似文献

The commercial airframe industry in the US experienced a shakeout from the early 1930s into the post‐Second World War period. Unlike shakeouts in automobiles, tyres, or televisions, the commercial airframe industry's early life cycle was affected by external factors, particularly government demand. Using newly digitized data on all planes introduced in the commercial market between 1926 and 1965, we find that commercial airframe manufacturers with bomber contracts during the Second World War were more likely to have postwar market share than firms without such contracts, controlling for plane characteristics and other forms of government contracting. We attribute the effect of bomber contracts to advantages in R&D learning capacity acquired by firms with military airframe contracts. Despite low (or zero) initial presence in the commercial market, these learning capacity advantages allowed such firms to survive the early period of the shakeout, and later to thrive. 相似文献

Age‐heaping‐based numeracy indicators have served as valuable tools to derive basic human capital estimates, especially for periods where other indicators are unavailable. However, the accuracy of individual age statements usually remains unknown, and due to the lack of precise information it can only be assumed that excessive occurrence of multiples of five in age distributions reflects inferior numerical skills. This article addresses this lacuna by identifying 162 individuals in two independent data sources: self‐reported age statements and independently kept records which are based on family heritage books and church registers. This method makes it possible to identify individual misreporting and the degree of accuracy of each individual. Findings show that not everyone who reported a multiple of five was reporting an incorrect age, nor was it the case that everyone who reported an age that was not a multiple of five was reporting an accurate age. The empirical analysis shows that the commonly used binary numeracy indicator is correlated with the observed degree of accuracy in age statements, and that a more sophisticated occupational background reduces this inaccuracy. These results tentatively suggest that the commonly used binary indicator measuring age heaping is a valuable proxy for numerical skills and occupational background in a population. 相似文献

The collapse of communism, the success of the US economy and the rise of the internet have led many to argue that the rest of the world should adopt American capitalism. This article uses evidence from the ancient Mediterranean and Middle East to argue that the most successful form of capitalism in each area (and era) depends on the context of the time, the culture of the people and the history of the region. 相似文献
