ABSTRACT The distribution of the cross-correlations of squared residuals from Box-Jenkins models is considered in very general conditions, and the asymptotic distribution is derived. A test for a lagged relationship in volatility for economic time series under instantaneous causality is proposed, and its empirical behaviour is studied. An example involving the international stock market's volatility is studied, and an interesting result is observed. 相似文献

We examine how no-fault divorce law affects the age at first marriage, when everyone has a different value of marriage. The heterogeneity of individual values implies an unambiguous negative effect on the variance of marriage age. We test this hypothesis with marriage records from 1970 to 1995. Controlling for state-level heterogeneity and for time trends, the standard deviation of the log age at first marriage drops by approximately 5% with the introduction of no-fault divorce. We find that the mean age at first marriage increases slightly, suggesting that the mean person is slightly worse off with no-fault divorce. (JEL K0 , D1 ) 相似文献

In the past four decades, Hong Kong has seen a dramatic transformation of the social location of women in the public sphere,
with deep and far-reaching ramifications for courtship, marriage, fertility, conceptions of parenthood, familial power, and
equality and freedom. A sociology of the family is thus by necessity a sociology of women in particular, and of gender relations
in general. Indeed, recent developments in research on marriage and the family in Hong Kong reflect this new awareness. Using
rigorous sociological frameworks, this new line of research has begun to meet with some success in analyzing contemporary
social issues that are prominent in the public consciousness. This essay reviews studies of four topical areas: determinants
of the postponement of first marriage among women, the effect of live-in foreign domestic workers on family dynamics, violence
against women and children in the family, and the livelihood strategies of cross-border families. These studies have attempted
to integrate the interplay of the impact of a changing economy and society on the family and the role played by women in the
family. The resulting dynamic interactions amongst the members within the family and the changes they bring about become propellants
for change in the economy and society and pose new challenges. The family is indeed a troubled institution. It is so because
myriad public issues are being taken on, confronted, worked through, and acted out within the family. The agony, and indeed
the ecstasy, of the family is a reflection of the success, and failure, of society. 相似文献

In an electoral system where each voter is allowed to select up to two candidates in a double-seat constituency, the combination of votes forms a special kind of contingency table. The usual hypothesis of complete independence of the voter shares for the candidates is of interest, but it is shown to be almost unattainable. The correlation coefficient of the voter shares is constructed. It is shown to be equivalent to Pearson's phi coefficient. The limitations of the coefficient are discussed. It is found that the use of conditional probabilities gives a better understanding of the dependence of the voter shares under the system considered. 相似文献

The first waves of Asian immigration to the United States were halted by exclusionary and racist legislation in the late nineteenth and early twentieth centuries. With the reforms of the 1965 Immigration Act, there has been a resurgence of immigration from Asia. This study analyzes changes in the socioeconomic composition of immigrant and native-born Asian-Americans (Japanese, Chinese, and Filipinos) from 1960 to 1976. The educational levels of all Asian groups, immigrant and native-born, have equaled or exceeded those of whites in recent years. Asians are more likely to be found in professional occupations than are whites, although there is also a concentration of immigrant Chinese and Filipinos in service occupations and the retailtrade sector. Native-born Asian-Americans have reached parity with whites in terms of average earnings, though immigrant Asians remain far behind. The findings are discussed in light of the changing structural conditions and opportunities of Asians in American society. 相似文献

This article develops a procedure to obtain highly accurate confidence interval estimates for the stress-strength reliability R = P(X > Y) where X and Y are data from independent normal distributions of unknown means and variances. Our method is based on third-order likelihood analysis and is compared to the conventional first-order likelihood ratio procedure as well as the approximate methods of Reiser and Guttman (1986) and Guo and Krishnamoorthy (2004). The use of our proposed method is illustrated by an empirical example and its superior accuracy in terms of coverage probability and error rate are examined through Monte Carlo simulation studies. 相似文献

An envelope-rejection method is used to generate random variates from the Watson distribution. The method is compact and is competitive with, if not superior to, the existing sampling algorithms. For the girdle form of the Watson distribution, a faster algorithm is proposed. As a result, Johnson's sampling algorithm for the Bingham distribution is improved. 相似文献

This study draws on survey data from 205 family mediation service users concerning their satisfaction with the outcomes of mediation to address two research questions: (a) how satisfied are service users? and (b) what factors account for users' satisfaction with the outcome of child custody arrangements and the allocation of finances and property? Overall, users' level of satisfaction with outcomes was high. While the mediation process explained a significant variance in satisfaction with the outcomes for child custody and for finances and property, the mediator's perceived professional competence did not predict user satisfaction with the outcomes for either issue. This study contributes to our knowledge on the significance of mediators' process skill, specifically their calm and clear responses to the socioemotional needs of the mediated parties, on the service outcomes for both types of dispute. The implications for mediation training are discussed. 相似文献
