The Impact of Museum Purchase on the Auction Prices of Paintings   总被引:1,自引:1,他引:0  
This study examines how art museumspurchasing policy influences the auction prices ofpaintings. Using a cross section of non-speculativetransactions during the period 1820–1970, we findconsiderable empirical support for the hypothesisthat public museums outside the U.S. pay above averageprices in auction markets providing higher thanaverage yields to private sellers. The typical U.S.private museums appear to be more restricted byfinancial constraints and the development of thegeneral economic conditions than their publiccounterparts.  相似文献

This paper contributes to the increasing research on how experts within financial institutions co-produce and organize financial markets, and in particular how equity analysts enact stock markets characterized by high volume and volatility. The 20 equity analysts studied give qualitatively different accounts of what, from an outsider's perspective, appear to be very similar work. The analysts understand investment objects, equity markets, and what constitutes good analytical work in qualitatively different ways. This heterogeneity, or multiplicity, could be one source of the, unexplained by orthodox financial theory, ‘excess’ volatility and ‘excess’ trading volume on financial markets. Therefore, the paper complements accounts within heterodox finance theory and sociology-based studies of financial market activities.  相似文献

Statistical and Fourier analysis methods of time series representing fluctuations of stock market in general and Indian stock markets in particular are well known. This work is motivated by a recent paper by Guharay [Operations Research and Financial Engineering, Princeton University, Princeton, NJ, preprint, 2002] where he has studied trends in the S & P 500 for various time periods using wavelet tools. Our paper deals with a few Indian and Saudi stock prices and return fluctuation for a certain period of time. The main objective of the analysis is to understand the dynamics of the Indian and Saudi stock markets. We look for similarities, point of abrupt changes, normalized data, return, volatility, graph, pure and noise part, correlation lengths, and signal-to-noise ratio.  相似文献

We evaluate the impact of the Gambian hardship allowance, which provides a salary premium of 30–40% to primary school teachers in remote locations, on the distribution and characteristics of teachers across schools. A geographic discontinuity in the policy's implementation and the presence of common pre-treatment trends between hardship and non-hardship schools provide sources of identifying variation. We find that the hardship allowance increased the share of qualified (certified) teachers by 10 percentage points. The policy also reduced the pupil–qualified teacher ratio by 27, or 61% of the mean, in recipient schools close to the distance threshold. Further analysis suggests that these gains were not merely the result of teachers switching from non-hardship to hardship schools. With similar policies in place in more than two dozen other developing countries, our study provides an important piece of evidence on their effectiveness.  相似文献

The dominant understanding of Internet censorship posits that blocking access to foreign-based websites creates isolated communities of Internet users. We question this discourse for its assumption that if given access people would use all websites. We develop a conceptual framework that integrates access blockage with social structures to explain Web users’ choices, and argue that users visit websites they find culturally proximate and that access blockage matters only when such sites are blocked. We examine the case of China, where online blockage is notoriously comprehensive, and compare Chinese Web usage patterns with those elsewhere. Analyzing audience traffic among the 1000 most visited websites, we find that websites cluster according to language and geography. Chinese websites constitute one cluster, which resembles other such geolinguistic clusters in terms of both its composition and its degree of isolation. Our sociological investigation reveals a greater role of cultural proximity than access blockage in explaining online behaviors.  相似文献
