Parent-Child Co-residence and Bequest Motives in China

In this paper, I discuss the actual conditions and the determinants of co-residence between older parents and their children in China, especially the impact of bequest motives on parent-child co-residence, using micro data from the gSurvey of Living Preferences and Satisfaction,h conducted at Osaka University. More specifically, I use three subsamples of older respondents (those who live in urban areas, those who live in rural areas, and the pooled sample of both) to analyze the impact of bequest motives and other factors on the probability of parent-child co-residence. The results are as follows: Bequest motives are strong in China, with more than 60 percent of respondents having a bequest motive, and the parent-child co-residence rate is also high (just under 60 percent). Bequest motives do not have a significant impact on the probability of parent-child co-residence in any of the three samples. However, in urban areas of China, if older parents own their own homes, the probability that they co-reside with their children increases as the value of their home increases. In rural areas of China and in the country as a whole, the coefficient of parental income is positive and significant in some cases, meaning that children are more likely to live with their parents if parental income is higher. All of these results suggest that, in both urban and rural areas of China, the Chinese are selfishly motivated and the life-cycle model applies.Bequest motives; parent-child co-residence; life-cycle hypothesis; altruism model; strategic bequest motive.

The gWillh to Save in China

In this paper, I discuss the actual conditions and determinants of the saving behavior and wealth holdings of the aged in China, with emphasis on the impact of bequest motives thereon, using micro data from the 2009 gSurvey of Living Preferences and Satisfactionh (urban households) and the 2010 gSurvey of Living Preferences and Satisfactionh (rural households), which were conducted in February 2009 and January 2010, respectively, as part of the Global Center of Excellence (GCOE) Program on gBehavioral Macro-dynamics based on Surveys and Experimentsh of the Graduate School of Economics and the Institute of Social and Economic Research of Osaka University. I found that bequest motives are strong in China, with more than 87 percent of respondents in urban areas, more than 75 percent in rural areas, and more than 85 percent in the country as a whole having a bequest motive, that these bequests are motivated primarily by altruism, that there is little evidence that aged households in China dissave (decumulate their wealth), and that altruistic and selfish bequest motives, especially the latter, increase the saving (or reduce the dissaving) of aged households.Bequest motives; saving behavior; wealth accumulation; life-cycle model; altruism model

Forecasting Value-at-Risk Using the Markov-Switching ARCH Model

This paper analyzes the application of the Markov-switching ARCH model (Hamilton and Susmel, 1994) in improving value-at-risk (VaR) forecast. By considering a mixture of normal distributions with varying variances over different time and regimes, we find that the “spurious high persistence†found in the GARCH model is adjusted. Under relative performance and hypothesis-testing evaluations, the VaR forecasts derived from the Markov-switching ARCH model are preferred to alternative parametric and nonparametric VaR models that only consider time-varying volatility.

Rdesign: A data dictionary with relational database design capabilities in Ada

Data Dictionary is defined to be the set of all data attributes, which describe data objects in terms of their intrinsic attributes, such as name, type, size, format and definition. It is recognized as the data base for the Information Resource Management, to facilitate understanding and communication about the relationship between systems applications and systems data usage and to help assist in achieving data independence by permitting systems applications to access data knowledge of the location or storage characteristics of the data in the system. A research and development effort to use Ada has produced a data dictionary with data base design capabilities. This project supports data specification and analysis and offers a choice of the relational, network, and hierarchical model for logical data based design. It provides a highly integrated set of analysis and design transformation tools which range from templates for data element definition, spreadsheet for defining functional dependencies, normalization, to logical design generator
