In this article, we establish optimal rates for the strong approximation of empirical copula processes in ?2 by sequences of Gaussian processes. These results are applied to investigate Cramér–von Mises-type statistics. 相似文献

In this paper, we provide the strong approximation of normalized empirical copula processes by a Gaussian process. In addition, we establish a strong approximation of the smoothed empirical copula processes and a law of iterated logarithm. 相似文献

Scrutinizing impacts of conspiracy theories on readers' political views: a rational choice perspective on anti‐semitic rhetoric in Turkey 下载免费PDF全文
Turkay Salim Nefes 《The British journal of sociology》2015,66(3):557-575
Although conspiracy theories have been politically significant throughout history, only a few empirical studies have been about their influence on readers' views. Combining a rational choice approach with a content analysis of an anti‐Semitic best‐selling conspiracy theory book series in Turkey – the Efendi series – and semi‐structured interviews with its readers, this paper reveals the effects of the conspiracy theories on readers' political perspectives. The findings suggest that whereas the rightists are reactive to the Jewish origins of the Dönmes, the leftists oppose the Dönmes as dominant bourgeois figures. This paper concludes that left‐ and right‐wing adherents use the conspiratorial accounts in line with their political views and ontological insecurities. It expands the existing academic literature, which conceptualizes conspiracy theories either as paranoid delusions or as neutral, rational narratives, by showing that they can be both. 相似文献

The main purpose of the present work is to introduce and investigate a simple kernel procedure based on marginal integration that estimates the regression function for stationary and ergodic continuous time processes in the setting of the additive model introduced by Stone (1985). We obtain the uniform almost sure consistency with exact rate and the asymptotic normality of the kernel-type estimators of the components of the additive model. Asymptotic properties of these estimators are obtained, under mild conditions, by means of martingale approaches. Finally, a general notion of the bootstrapped additive components, constructed by exchangeably weighting sample, is presented. 相似文献

Corporate governance and market performance of parent firms following equity carve-out announcements
Using the Gompers, Ishii, and Metrick corporate governance index on a sample of 158 parent firms, this study demonstrates that firms with a superior governance rating have a higher short-term market reaction to carve-out announcements relative to firms with an inferior governance rating. Although the data supports previous evidence regarding negative long-term market reaction that parent firms typically experience following equity carve-outs, the results show that well-governed firms marginally outperform others. The findings also confirm that the dynamic effects related to improvements in corporate governance positively affect the long-term market outcome of parent firms; this relation is more significant in well-governed parent firms. Finally, the study shows evidence that corporate governance helps mitigate the agency problems related to the financing hypothesis, which results in better short and long-term market reactions following carve-out announcements. 相似文献

This paper investigates the effect of board size and its composition on bank’s performance in an emerging context. This study
includes 749 firm years of data on the banking industry in Lebanon from 1992 to 2006. The data contains all nationwide banks
in operation in any year over the studied period. Since some banks entered and/or exited over the sample period, there is
an unbalanced panel data, where an Ordinary Least Squares regression may create problems of interpretation. Within this framework,
we use a fixed-effect model which produces unbiased and consistent estimates of the coefficients. This paper reports that
bank performance is positively related to board size. It also identifies a quadratic relationship between bank performance
and board independence. Both return-on-assets and return-on-equity first decrease and then increase in direct proportion to
the increased percentage of outside directors on the board. This paper sheds some light on the differential impact of corporate
governance on firm performance across industries and countries. It concentrates on banks in developing countries that are
generally known to suffer from high asymmetric information and where concerns about safety and soundness remain. Hence, it
contributes to the existing debate on appropriate regulations for an effective and stable financial system in the Arab world.
Also, it complements the Basel Committee standards for bank supervision and capital adequacy reinforcement, and offers regulators
some evidence on the relationship between board size and bank performance in a developing country such as Lebanon. 相似文献

This article develops a computable general equilibrium model of Vietnam to assess the long-run likely effects of the country's equitisation programs on its national economic outcomes and industries. Equitisation is found to be pro-growth as reflected in its contribution to increasing real GDP growth rate in the long run. In terms of industrial output growth rates, the winners include electrical, steel and other manufacturing, while the losers include rice and paddy, and oil, gas and petroleum. To achieve better economic outcomes, the coverage of equitisation should be extended to include medium to large state-owned enterprises across all industries. 相似文献

We study the behavior of bivariate empirical copula process 𝔾 n (·, ·) on pavements [0, k n /n]2 of [0, 1]2, where k n is a sequence of positive constants fulfilling some conditions. We provide a upper bound for the strong approximation of 𝔾 n (·, ·) by a Gaussian process when k n /n↘γ as n → ∞, where 0 ≤ γ ≤1. 相似文献

We introduce some new nonparametric statistical tests of symmetry. The limiting behaviors of the proposed statistics are established under the null hypothesis. Emphasis is placed on explanation of the strong approximation methodology. The asymptotic validity of a re-sampling method to compute p-values is also established. A simulation study for some considered statistics is performed. 相似文献
