We study the pricing mechanisms and information content of block trades on the Shanghai Stock Exchange (SSE) for the six year period from 2003 to 2009.There is an average of about 4% block discount, which is large in magnitude and statistically significant, reflecting compensation for locating counterparties and the cost of negotiating terms. We also examine permanent price impacts of the trades and find that discount block trades (DBTs) have significant negative permanent price impacts for various periods extended up to 60 trading days after the block trades. Conversely, premium block trades (PBTs) have small and statistically insignificant negative permanent price impacts, suggesting that buyers do not possess valuable private information. Finally, we classify the trades into buys and sells using a set of stricter rules and note similar results to those of DBTs and PBTs. Of additional note, block sells on stocks with expirations of restricted shares seem to have significant information content. As these trades are more likely to be originated from insiders, our results suggest that they strategically time the sale of these shares to maximize gains. 相似文献

In contrast to arguments that flexible manufacturing systems (FMS) are highly versatile configurations that are only prevented from machining a wide range of parts by extrinsic constraints, this article contends that FMS are a genre of configurations that combine flexibility and intrinsic constraints in a variety of permutations, depending on a user's intended objectives. Empirical evidence is used to identify the factors that shape the levels of constraint in particular FMS and to identify instances where intrinsic constraints impede performance. Suggestions are made for initiatives to facilitate the continued use of FMS with the highest levels of intrinsic constraints that have hitherto hindered performance when the FMS users' manufacturing needs changed. Occupational structures that promote a polarization between staff with engineering knowledge and those responsible for defining general strategic objectives are suggested as a potential obstacle to such initiatives. 相似文献

We propose a new class of models specifically tailored for spatiotemporal data analysis. To this end, we generalize the spatial autoregressive model with autoregressive and heteroskedastic disturbances, that is, SARAR(1, 1), by exploiting the recent advancements in score‐driven (SD) models typically used in time series econometrics. In particular, we allow for time‐varying spatial autoregressive coefficients as well as time‐varying regressor coefficients and cross‐sectional standard deviations. We report an extensive Monte Carlo simulation study in order to investigate the finite‐sample properties of the maximum likelihood estimator for the new class of models as well as its flexibility in explaining a misspecified dynamic spatial dependence process. The new proposed class of models is found to be economically preferred by rational investors through an application to portfolio optimization. 相似文献

This paper empirically examines the impact of the US stock market on Australian economic activity as one explanation of the strong correlation in the Australian and US business cycles. It is found that both the US and Australian share markets appear to have a significant impact on Australian activity. 相似文献

We advance the measurement of trust in economics in two ways. First, we highlight the importance of clearly identifying the target of trust, particularly for obtaining concordance between attitudinal and behavioral measures of trust. Second, we introduce a novel behavioral measure of (dis)trust, based on individuals? willingness to pay to avoid being vulnerable to the target of trust. We conduct an experiment in which we vary the target of trust among passersby at several locations around a city, measuring both behavioral distrust and trust attitudes towards these varying targets. We find that subjects discriminate based on perceived characteristics of different targets in determining whether to trust, in a manner consistent with trust elicited using attitudinal measures and with actual trustworthiness. Risk aversion and altruism do not correlate highly with our measure of distrust. 相似文献

This article summarizes the most significant developments in survey sampling in the twentieth century, especially as they
relate to marketing and marketing research, and attempts to predict, based on what we know now, significant developments that
will occur early in the twenty-first century. The article is divided into the following sections: (1) Developments in Door-to-Door
Sampling, (2) Developments in Telephone and Mail Surveys, (3) Location Samples, (4) Focus Groups and Other Sloppy Samples,
(5) Sampling Rare Populations, (6) Business Surveys, (7) Panels, (8) Developments in the Theoretical Foundation of Survey
Sampling, and (9) The Evolutionary Process and Future Developments.
Seymour Sudman is Walter A. Stellner Professor of Marketing and the deputy director of the Survey Research Laboratory at the University
of Illinois, Urbana-Champaign. He is the author, co-author, or editor of 20 books and more than 200 articles dealing with
sampling and survey methods.
Edward Blair is a professor of marketing and entrepreneurship at the University of Houston and the head of the department. He is the author
(with Seymour Sudman) of a text on marketing research, and his articles on research procedures have appeared in various academic
journals. He also has taught sampling and other topics at the American Marketing Association’s School of Marketing Research
since its inception. 相似文献
