Knowledge is a vital source of competitive advantage and renewal for contemporary organizations. However, to date, few studies have scrutinized how mergers and acquisitions (M&As)—processes dependent on knowledge sharing—offer a valuable inter-organizational context through which to understand the attainment of customer knowledge sharing following M&As. Applying an integrated theoretical perspective from customer relationship management and M&A performance research, we study a Chinese–Finnish acquisition and customer firms of the acquired party across four advanced Western countries. We find that customer knowledge sharing is an active relationship management process that relies on the factors of customer dedication-based motivation vs. customer concerns about M&As to maintain relationships after acquisitions. In addition, and more importantly, we find that the promise management mechanisms—making promises, enabling promises, and keeping promises—of the M&A parties reinforce the motivational factors to maintain customer knowledge sharing in cross-border M&As. We propose a conceptual framework of customer knowledge sharing in cross-border M&As.  相似文献

The association between sociodemographic, demographic, and attitudinal measures and the timing or tempo of marital dissolution over a 14-year time span is examined. Separation is considered equivalent to divorce. Early and late divorce are differentiated by whether the event occurred before or after the average number of years married prior to divorce. Data were obtained on husbands and wives within childbearing years (up to 39 years) in the 1st years of the 1st marriage. A random stratified sample of 610 couples was drawn from records of marriages in a midwestern county between 1972-77. Reinterviews were conducted on 544 couples in April 1985. socioeconomic variables included educational attainment, occupational prestige, wife's employment status, wife's future work plans, husband's attitude to wife's future work plans, total family income, and level of satisfaction with current financial status. Demographic variables are age at marriage, number of children in 1985, marital duration, and desired family size. Attitudinal items were religiosity and gender role orientations (traditionalism, modernism, egalitarianism). Exposure to divorce was not equitably distributed for the 108 who divorced, but this was not statistically significant. The results indicate that those divorced earlier were wives who worked outside the home, worked at more prestigious jobs, planned to be employed throughout married life, and whose father had a higher level of educational attainment. This finding is not consistent with prior research which has shown that favorable socioeconomic conditions lower the probability of divorce. The timing of divorce was affected by the presence of children. Those married at younger ages divorced earlier and couples with children delayed divorcing longer than couples without children. These findings were consistent with earlier research. Catholic wives delayed divorce longer than non-Catholic wives. Males lower in sexual satisfaction divorced earlier. Divorce was postponed longer for husbands with traditional values and wives who had higher scores on egalitarianism. Wives with scores on modernism had earlier divorces than wives scoring lower on modernism. The tempo of divorce was in multiple classification analysis predicted best by wife's employment status and number of children. Cross-classification was not possible.  相似文献

"This paper evaluates age, period, and cohort effects on marital fertility during onset of the Utah fertility transition (1880-1900). Computerized genealogies are used to derive age-period-cohort fertility rates for 49,842 once-married couples. Age, period and cohort effects on marital fertility are then estimated using Johnson's (1985) relational model. Declining marital fertility in Utah is shown to be explained by both lower fertility levels across periods and increasing age-specific limitation across cohorts. Direct cohort effects on fertility are insignificant. These results are consistent with prior research, and the view that fertility levels were adaptive (in part through birth spacing across ages) to immediate contexts of childbearing while age-specific fertility truncation increased across cohorts (in part through the more general diffusion of contraceptive innovations)."  相似文献

"The prospects for today's second generation will be considerably shaped by their current social, economic and demographic status. This article provides a statistical portrait of children of immigrants by analyzing data from the 1990 U.S. Census of Population and Housing. With the second generation defined as children under age 18 with at least one foreign-born parent, the study describes place of residence; household demographic, social and economic circumstances; household head's socioeconomic status; and characteristics of children themselves. Data on second-generation children are broken down by year of immigration of parents and child's nativity. Data for children with native-born parents are provided for comparison."  相似文献

"This paper focuses on the effects of age at marriage and the sex-ratio on patterns of ethnic homogamy among Israeli women. We hypothesize that later marriages are more likely than early marriages to be heterogamous as the 'marriage market' shifts from school to the work-place. By the same token, when facing severe marriage squeezes women will be forced to out-marry. Employing data from the 1983 census, we model mate selection of women from Afro-Asian and Euro-American origin in various birth-cohorts. The results do not fully support our hypotheses: we find that in and of itself, age at marriage does not enhance ethnic heterogamy."  相似文献

"The purpose of this paper...is twofold: first, to specify a way of calculating place utility so that potential migrants could move to the place where overall place utility is maximized; and second, which is more important, to reveal how decision-makers in the real world, who are acting within 'bounded rationalities'...,make their decisions on where to migrate. This study is supported by an empirical survey of recent Chinese immigrants to Edmonton [Canada].... The findings reveal that when people evaluate different places, they do not necessarily look for the one that generates the highest overall value or utility across all properties.... The study further indicates that the assumption underlying most microeconomic models (that maximizing utility or benefit is the ultimate rule for choosing one location out of several) has not been verified."
