Evidence of Stock Returns and Abnormal Trading Volume: A Threshold Quantile Regression Approach 下载免费PDF全文
This paper presents a capital asset pricing model‐based threshold quantile regression model with a generalized autoregressive conditional heteroscedastic specification to examine relations between excess stock returns and “abnormal trading volume”. We employ an adaptive Bayesian Markov chain Monte Carlo method with asymmetric Laplace distribution to study six daily Dow Jones Industrial stocks. The proposed model captures asymmetric risk through market beta and volume coefficients, which change discretely between regimes. Moreover, they are driven by market information and various quantile levels. This study finds that abnormal volume has significantly negative effects on excess stock returns under low quantile levels; however, there are significantly positive effects under high quantile levels. The evidence indicates that each market beta varies with different quantile levels, capturing different states of market conditions. 相似文献

This paper reviews the basic principles of inequality measurement, underlining the advantages and shortcomings of alternative measures from a theoretical standpoint and in the context of the study of the distribution of wealth. Adopting the two most popular measures, the Gini index and the P‐shares, the paper documents wealth inequality in Canada using the 1999, 2005 and 2012 Survey of Financial Security (SFS). It carries out several decompositions with covariates, featuring DFL‐type reweighting methods and Gini and P‐shares RIF regressions. The latter parallel decompositions deepen our understanding of how changes in socio‐demographic characteristics, including the compensating role of family formation and human capital, impact wealth inequality. 相似文献

While innovators may rush to purchase many new products, most consumers are more conservative and do not want to buy into fads but purchase only those new products that are viable. How do the majority of consumers make judgments about whether they will adopt an innovation? This article examines the evaluative aspects of adoption as a means for better understanding consumer adoption and the market factors that may influence the success of an innovation. This research introduces a conceptual model that shows how consumers’ evaluation of product category attractiveness affects the adoption decision for really new products. These consumer evaluations are based on the attributes of the product category (“extrabrand” attributes) rather than brand attributes. Results from a test of the model indicate that consumers do use extrabrand attributes to assess the attractiveness of innovative new products. 相似文献

This study presents a two-phase model of interfirm exchange in the logistical supply industry. The first phase uses transaction
cost analysis to identify conditions leading to market-based transactions, unilateral agreements, and bilateral alliances.
The second phase illustrates how formal controls and relational norms yield performance in market, unilateral, and bilateral
governance systems. A test of the model with data from 189 logistical supply relationships suggests that bilateral alliances
emerge through the interaction of user investments in the logistics supplier, supplier logistical services, and marketplace
uncertainty. Bilateral alliances attain desired outcomes through participative management and flexibility. By contrast, market-based
transactions yield desired outcomes through formalization and solidarity. Unilateral agreements gain performance through formalization,
participation, information sharing, and solidarity. Implications for logistics management and theory are discussed.

We test for causality between inflation and its associated uncertainty by means of both in-sample and out-of-sample modelling. Our findings indicate that the impact of inflation on inflation uncertainty is more pronounced than the reverse causal effect. 相似文献

We investigate price clustering of intraday trades and negotiated block trades on the Shanghai Stock Exchange (SSE) from 2003 to 2009. Prices of traded assets tend to cluster on certain final digits, such as 0 and 5. In Chinese culture, 8 is associated with good luck and 4 with death so these numbers may be attractive or avoided. We find that price clustering on the final digit of 0 is significantly higher during the morning call auction and early in the trading day. We find no evidence of price clustering for the digit 8, but there is a significant dearth of prices ending in the inauspicious number 4. Price clustering is significantly higher for negotiated block trades, for which about 28% end with 0. Multivariate analysis shows that price clustering is lower for more liquid firms, but higher for firms with higher return volatility, a higher price level, or when the market is volatile. Our evidence supports the costly negotiation hypothesis. Our results also support the attraction hypothesis in that we document significant price clustering at round numbers and even numbers even after controlling for factors that are associated with price uncertainty. 相似文献

Assessing the Impacts of Capital Inflows on Domestic Economy across the Sub-Saharan Africa Countries
Using GMM models, this paper analyzes the impacts of capital inflows on domestic investment in 44 Sub-Saharan Africa (SSA) countries from 2003–2012. It is found that foreign direct investment across the SSA remains to be the largest percentage share, accounting for 35% of the total capital inflows. FDI inflows have significant positive impacts on domestic investment across the SSA in both short term and long term. Other key macroeconomic factors such as age dependency ratio, domestic economic growth, terms of trade, real effective exchange rate and trade openness also play vital roles in determining domestic investment. 相似文献

This paper deals with the optimal regulation for cost-reducing R&D and pricing in natural monopoly that is privately informed on its efficiency. We extend the work of Cantner and Kuhn (Rev Econ Des 4:191–204, 1999) and then we are able to analyse the entire effects of the interplay between agent’s efficiency and investment in R&D particularly considering the substitutability case. 相似文献
