小额信贷之违约概率模型:特别考虑异质性

在新巴塞尔资本协议(New Basel Capital Accord)对金融全球化的冲击及金融机构改善资产质量及合并政策的影响下,我国台湾地区金融业进入激烈合并竞争的时代.许多银行颇受降低逾放比率及增加净值报酬率与资产报酬率两难之困扰.消费性信用贷款产品利差大、风险分散,是金融机构授信经营极重要的产品.实证结果显示,采用世代研究(cohort study)建立之模型对样本数据之拟合程度较个案对照研究法(case-control study)的解释变异量为佳,且较符合新巴塞尔资本协议规定及科学程序.虽然Logistic 回归模型在建立逾期概率模型上广泛地被使用,但要求存在于同构型的变异数Var=np(1-p)假设上,且在数据分析上常因为出现变异数之异质性问题,故可采用调整变异数异质性之方法.     

The Gender Revolution: A Framework for Understanding Changing Family and Demographic Behavior

This article argues that the trends normally linked with the second demographic transition (SDT) may be reversed as the gender revolution enters its second half by including men more centrally in the family. We develop a theoretical argument about the emerging consequences of this stage of the gender revolution and review research results that bear on it. The argument compares the determinants and consequences of recent family trends in industrialized societies provided by two narratives: the SDT and the gender revolution in the public and private spheres. Our argument examines differences in theoretical foundations and positive vs. negative implications for the future. We focus primarily on the growing evidence for turnarounds in the relationships between measures of women's human capital and union formation, fertility, and union dissolution, and consider evidence that men's home involvement increases union formation and fertility and decreases union instability. Although the family trends underlying the SDT and the gender revolution narratives are ongoing and a convincing view of the phenomenon has not yet emerged, the wide range of recent research results documenting changing, even reversing relationships suggests that the gender approach is increasingly the more fruitful one.     

Parenthood and Leaving Home in Young Adulthood

With increases in nonmarital fertility, the sequencing of transitions in early adulthood has become even more complex. Once the primary transition out of the parental home, marriage was first replaced by nonfamily living and cohabitation; more recently, many young adults have become parents before entering a coresidential union. Studies of leaving home, however, have not examined the role of early parenthood. Using the Young Adult Study of the 1979 National Longitudinal Survey of Youth (n = 4,674), we use logistic regression to analyze parenthood both as a correlate of leaving home and as a route from the home. We find that even in mid-adolescence, becoming a parent is linked with leaving home. Coming from a more affluent family is linked with leaving home via routes that do not involve children rather than those that do, and having a warm relationship with either a mother or a father retards leaving home, particularly to nonfamily living, but is not related to parental routes out of the home.     

The management of managers: Disputing in an executive hierarchy

This paper focuses on the relationship between organizational rank and respectability and the way top managers handle their interpersonal grievances, conflicts, and disputes in an executive hierarchy. Formal grievance procedures are rarely used. Downward grievances (from a superior to a subordinate) are often settled unilaterally by the superior. Upward grievances are typically handled covertly by subordinates. Titular equals opt for a range of covert and confrontational tactics, many of which evolve into disputes and are settled by a common superior. Respectability within the executive ranks appears to enhance the ability of superiors to impose outcomes on grievances, conflicts, and disputes between and within subordinates, to decrease the hostility of upward grievances, and to decrease vulnerability of subordinates to sanctions by their superiors.An earlier version of this paper was presented at the Annual Meeting of the Law and Society Association, Washington, DC, June 1987.     

Interpolating demography with families and households

This paper argues that the field of household and family demography serves a critical role in the development of our understanding of the determinants and consequences of population trends. Like the community, families and households are situated between the two levels at which demographic research is ordinarily conducted — the individual and the nation-state. The results of the papers in this issue are used to illustrate the critical ways that intergenerational and gender relationships shape demographic processes.     

DO MEN “NEED” A SPOUSE MORE THAN WOMEN?: PERCEPTIONS OF THE IMPORTANCE OF MARRIAGE FOR MEN AND WOMEN

This study examines how important men and women feel marriage is for men and for women. Using data from the National Survey of Families and Households, we find that both men and women feel that men need to be married more than women do. Women are more likely than men to think that both men and women can have satisfying lives without marriage, but they are also more likely to think that only women can have satisfying lives without marriage. Younger, more educated people are less likely to emphasize marriage. On the other hand, religious people and those who are married with children are particularly likely to think that neither men nor women can have satisfying lives without marriage.     

Allocation of research and development funds: A zero-one goal programming approach

The research and development project selection process is one of the most difficult and important problems faced by management. It is typically complicated by indivisibility of projects and multiple and conflicting objectives, in addition to limitations on funding, facilities, and qualified researchers. In this paper a case example involving a high technology electrical equipment manufacturer is developed to illustrate this problem using zero—one goal programming to accommodate indivisibility of projects in addition to multiple and conflicting goals. The model presented is an attempt to provide managers with a robust tool for allocating scarce resources among research and development projects.     

Slave Trading in a Republic of Credit: Financial Architecture of the US Slave Market, 1815–1840

Credit facilitated the intra-US slave trade's growth between 1815 and the financial crisis of the late 1830s. Movement of money across geographic space was the enslavers’ chief challenge, and this article details the process of slaving firms’ building credit and remitting funds with which they constructed supply chains in bondspersons. Slave market development was dependent on US and North Atlantic financial integration and comprised three stages. These included use of the Second Bank of the USA, supplemented by domestic bills of exchange, and culminating in the use of southern state banks with northern correspondent ties, which the financial crisis severed.     

Growing Parental Economic Power in Parent–Adult Child Households: Coresidence and Financial Dependency in the United States, 1960–2010

Research on coresidence between parents and their adult children in the United States has challenged the myth that elders are the primary beneficiaries, instead showing that intergenerationally extended households generally benefit the younger generation more than their parents. Nevertheless, the economic fortunes of those at the older and younger ends of the adult life course have shifted in the second half of the twentieth century, with increasing financial well-being among older adults and greater financial strain among younger adults. This article uses U.S. census and American Community Survey (ACS) data to examine the extent to which changes in generational financial well-being over the late twentieth and early twenty-first centuries have been reflected in the likelihood of coresidence and financial dependency in parent–adult child U.S. households between 1960 and 2010. We find that younger adults have become more financially dependent on their parents and that while older adults have become more financially independent of their adult children, they nevertheless coreside with their needy adult children. We also find that the effect of economic considerations in decisions about coresidence became increasingly salient for younger adults, but decreasingly so for older adults.
