An evaluation of the childhood family structure measures from the sixth wave of the British Household Panel Survey

Summary.  The paper performs an evaluation of the data that were collected in the sixth wave of the British Household Panel Survey (BHPS) on childhood family structure. After comparing such data with a large number of studies by using external sources, we find that the BHPS data overestimate the proportion of people who report an experience of life in a non-intact family during childhood by about 10%. Although an explanation based on recall error that deteriorates with the age of the BHPS respondents is possible, the overestimation is likely to be accounted for by non-ignorable attrition that may affect most of the comparison studies based on longitudinal data. Conversely, comparisons with other independent measurements from the BHPS itself reveal that the wave 6 data underestimate the proportion of young people who have lived at least part of their childhood in a non-intact family by about 8%. The probability of disagreement between these two sets of measures is strongly associated with poor interview characteristics, which may affect the comparison measure more than the wave 6 measure. Despite such differences, there is therefore a substantial degree of similarity between the family structure information that was collected in the sixth wave of the BHPS and the host of highly diverse records against which it has been compared.     

历史小说：在家庭文化的认同与互动之间

家庭文化对于历史小说家的审美趣味和历史观念具有重要影响,家学传统给予历史小说家的文化熏陶对于历史小说写作具有重要意义,情感的苦乐体验使作家对历史小说如何以史鉴今重塑中国文化和民族精神有着独特理解,但家庭文化的负面因素也造成了历史小说的缺憾和不足。     

Using a computer simulation game to teach family time use concepts

A computer simulation game designed to give students insights into family time use concepts has been used in an introductory family resource management class at Ohio State University and other universities. The game allows for planning for time use changes over the family life cycle. The game can give students insights into economic and sociological models of time use. It is possible that future versions of the game could be used in family counseling.His research interests include derivation of optimal decision-making rules for families and family financial management.Her research interests include financial management over the life course including financial ratios, baby boomers, and retirement.

The ecosystem blueprint: How firms shape the design of an ecosystem according to the surrounding conditions

Ecosystems are formed by organisations that jointly create a value proposition that a single firm could not create in isolation. To deliver this value proposition, the partners need a focal firm, the orchestrator, to be align them towards the joint value proposition. Thus, how orchestrators design the alignment structure of an ecosystem is at the very heart of the ecosystem concept – yet it has not been sufficiently addressed by extant research. This is all the more true for the question of how the design of an ecosystem is shaped depending on surrounding conditions. This paper applies a qualitative study with ten cases and, based on the attention-based view of the firm, contributes to research on ecosystems in several ways. First, it explains which ecosystem designs are beneficial under which conditions. Second, it elucidates the structure and activities within ecosystems and shows that start-ups can be just as good ecosystem orchestrators as incumbents. Third, it explains the circumstances under which single vs. multi orchestrator ecosystems occur. Fourth, it presents the conditions when incumbents or start-ups make better orchestrators. Finally, it is among the first studies to apply the attention-based view to business ecosystems, and shows that doing so yields intriguing insights into this emerging field of research.     

融资约束下金融科技对投资和公司价值的影响

融资约束与非效率投资限制了公司价值的增长。针对这一问题,以地区金融科技的发展对融资约束企业的投资行为和公司价值的影响为切入点,通过构造PVAR模型研究变量之间的动态关系。选取2011-2020年中国沪深交易所上市公司的数据进行了融资约束划分后,最终确定362家上市公司作为研究对象。SGMM回归结果表明,金融科技的发展在短期内能够缓解企业的融资约束程度,促进投资的发生,缓解投资不足的现象,进一步提升公司价值。通过脉冲响应函数分析可知,金融科技的发展对企业价值的影响是动态变化的,从长期的影响来看这可能是一把双刃剑;金融科技会通过缩短融资约束企业的投资滞后期数,促进企业投资效率和公司价值的提升。     

Generalized Leverage and its Applications

The generalized leverage of an estimator is defined in regression models as a measure of the importance of individual observations. We derive a simple but powerful result, developing an explicit expression for leverage in a general M -estimation problem, of which the maximum likelihood problems are special cases. A variety of applications are considered, most notably to the exponential family non-linear models. The relationship between leverage and local influence is also discussed. Numerical examples are given to illustrate our results     

Financial management: Development of scales

This study is a contribution to the development of family resource management scales, specifically financial management scales. Principal axis factor analysis, with varimax rotation, is used to assess underlying relationships in 23 family resource management variables related to time and money resources. Reliability and content, construct, and criterion-related validity of the scales are assessed. Two scales that are reliable and have some degree of validity are developed: frequency of financial problems and frequency of financial management. The scales could be used in future research, teaching, or counseling to organize financial management concepts.Preparation of this research was supported in part by the Illinois Agricultural Experiment Station. Data were collected in conjunction with the cooperative regional research project NC-182, Family Resource Utilization as a Factor in Determining Economic Well-Being of Rural Families.

Corporate Management,Industry Competition and the Sustainability of Firm Abnormal Profitability

This paper models the sustainability of firmabnormal profitability and uses theeffectiveness of corporate managementcapabilities as a test to examine its impact onthe sustainability of firm abnormalprofitability. The role of industry competitionas a moderator between the effectiveness ofcorporate management capabilities and thesustainability of firm abnormal profitabilityis also examined. Consistent with theresource-based view of the firm, we found thatthe effectiveness of corporate managementcapabilities positively influence thesustainability of firm abnormal profitability.This implies that corporate managementcapabilities are important contributors to theentire bundle of firm-specific resources andcapabilities which enable some firms togenerate competitive advantages that aresustainable. The effectiveness of corporatemanagement capabilities has a larger influenceon the sustainability of firm abnormalprofitability for firms in lowly competitive ormonopolistic industries than firms in highlycompetitive industries. The findings supportthe notion that not only do firm capabilitiesyield sustainable competitive advantages andabnormal profitability, but also industrycompetition reinforces the impact of firmcapabilities in yielding sustainable abnormalprofitability.
