Retirement patterns in Hong Kong: a censored regression analysis

This paper provides an overview of retirement patterns in Hong Kong on the basis of limited data. A censored regression model is used to infer the retirement age from people‘s current retirement status and their current age. This model is equivalent to a restricted probit model, and the interpretation of parameters is straightforward. The results clearly show a negative income effect on the retirement decision. The retirement age seems to be positively related to lifetime earnings but negatively related to the rate of decline of earnings with age.

Career Mobility in a Global Era: Advances in Managing Expatriation and Repatriation

The surge of interest in expatriation and repatriation within the broader discourse on labor mobility of professionals and high-skilled labor, human capital development, and the theory and practice of people management serves as the backdrop to this paper. We propose that expatriation and repatriation be framed in the context of global careers and embedded in the wider social-economic environment of globalization through the lens of a career ecosystem theory. We chart the evolution of scholarly publications on career mobility over the past four decades and highlight current trends, in particular the emergence of self-initiated expatriation as a pivotal change in the direction of expatriation studies and derived practice. We assess the rigor of empirical findings, weigh theoretical underpinnings, offer a research agenda for future research, and outline managerial implications.     

Age structure of the workforce in growing and declining industries: evidence from Hong Kong

Industry-specific human capital reduces the incentive for older workers to leave declining industries and raises the incentive for younger workers to join growing industries. Using the industry restructuring experience of Hong Kong, we find that a 1% increase in employment share of an industry is associated with a 0.60-year decrease in the average age of its workforce. The relationship is more pronounced among less educated workers, who have less general human capital, and male workers, who are more committed to the labor force, than among well educated workers and female workers.     

A DIRECT TEST OF THE EFFICIENT MARRIAGE MARKET HYPOTHESIS

This paper takes Becker's efficient marriage market hypothesis at face value, and directly confronts it with data from Hong Kong. The theory of optimal assignment is used to develop an empirical model of spouse selection, which resembles a Tobit model. This model can address positive or negative assortative matching as well as marginal product pricing in marriage markets. We also use a computer algorithm to solve the assignment problem for imputed marital output. The degree to which the actual pairing of husbands and wives corresponds to the optimal pairing provides a goodness-of-fit test of the efficient marriage market hypothesis.

STATISTICAL MODELS OF CONSUMER BEHAVIOR WITH HETEROGENEOUS VALUES AND CONSTRAINTS

In a market with heterogeneous individuals, the fact that a particular group of individuals are the consumers of a particular product already indicates that there exist systematic differences between them and the average person. Simple tools from statistical theory are used here to analyze the implications of consumer diversity. It is argued that an increase in consumer diversity will increase the gains from trade, and that there is a "shadow price of heterogeneity" associated with product quality. Throughout the discussion, the significance of consumer self-selection and the distinction between "average" and "marginal" will be emphasized.     

Some resolvable orthogonal arrays with two symbols

A method of constructing a resolvable orthogonal array (4λk2,2) which can be partitioned into λ orthogonal arrays (4,k 2,1) is proposed. The number of constraints kfor this type of orthogonal array is at most 3λ. When λ=2 or a multiple of 4, an orthogonal array with the maximum number of constraints of 3λ can be constructed. When λ=4n+2(n≧1) an orthogonal array with 2λ+2 constraints can be constructed. When λ is an odd number, orthogonal arrays can be constructed for λ=3,5,7, and 9 with k=4,8,12, and 13 respectively.     

No-Fault Divorce and the Compression of Marriage Ages

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 )

Patterns of Sensitivity to Parenting and Peer Environments: Early Temperament and Adolescent Externalizing Behavior

Although parenting behavior and friendship quality predict adolescent externalizing behaviors (EBs), individual differences in temperament may differentially affect susceptibility to these factors over time. In a multi‐method and multi‐informant study of 141 children followed prospectively from toddlerhood to adolescence, we tested the independent and interactive associations of age 3 reactive temperament (e.g., negative emotionality) and age 13 observed parenting (i.e., positive and negative behavior) and friendship (i.e., conflict and warmth), with multi‐informant ratings of age 15 aggression and rule‐breaking behavior. Negative parenting predicted growth in parent‐rated EB, but only for adolescents with early reactive temperament. Temperament did not affect sensitivity to positive parenting or friendship. Results are discussed in the context of differential susceptibility theory and intervention implications for adolescents.
