Knowledge transfer in MNCs: Examining how intrinsic motivations and knowledge sourcing impact individual centrality and performance

Studies investigating individual performance in knowledge-intensive work are finding that individual performance is a result, to some degree, of obtaining the right information to solve novel, challenging problems. Yet we know little about the role that the individual plays in the knowledge processes in multinationals and the relationship between individual knowledge sourcing activities and performance. Our expectation is that successful knowledge transfer will be based on an individual's intrinsic motivation, access to knowledge from explicit or tacit knowledge sources within and across firm boundaries, and position in the overall advice network of the multinational corporation. Using survey and social network data collected in one multinational consulting firm, we investigated the knowledge sourcing activities and informal advice networks for 1439 of the entire 1698 individuals in one multinational spread across 28 offices (84.7% response rate). Through hierarchical regression analysis we find that 1) intrinsic motivations are strongly related to creativity and efficiency and 2) MNCs should support individual level activities that include not only the use of internal knowledge sources but also the use of external knowledge sources. Research results also suggest that 3) there are different patterns of knowledge sourcing activities based on whether efficient or creative performance is the goal and 4) these differ significantly depending upon the functional group to which the individual belongs. Implications for theories of the knowledge-based view of the multinational corporation and practical implications for managers are discussed.     

Maximum penalized likelihood estimation of mixed proportional hazard models

Unobservable individual effects in models of duration will cause estimation bias that include the structural parameters as well as the duration dependence. The maximum penalized likelihood estimator is examined as an estimator for the survivor model with heterogeneity. Proofs of the existence and uniqueness of the maximum penalized likelihood estimator in duration model with general forms of unobserved heterogeneity are provided. Some small sample evidence on the behavior of the maximum penalized likelihood estimator is given. The maximum penalized likelihood estimator is shown to be computationally feasible and to provide reasonable estimates in most cases.     

Production Frontiers and Panel Data

Value at risk (VaR) is the standard measure of market risk used by financial institutions. Interpreting the VaR as the quantile of future portfolio values conditional on current information, the conditional autoregressive value at risk (CAViaR) model specifies the evolution of the quantile over time using an autoregressive process and estimates the parameters with regression quantiles. Utilizing the criterion that each period the probability of exceeding the VaR must be independent of all the past information, we introduce a new test of model adequacy, the dynamic quantile test. Applications to real data provide empirical support to this methodology.     

On the Dynamics of Unemployment and Wage Distributions

Postel‐Vinay and Robin's (2002) sequential auction model is extended to allow for aggregate productivity shocks. Workers exhibit permanent differences in ability while firms are identical. Negative aggregate productivity shocks induce job destruction by driving the surplus of matches with low ability workers to negative values. Endogenous job destruction coupled with worker heterogeneity thus provides a mechanism for amplifying productivity shocks that offers an original solution to the unemployment volatility puzzle (Shimer (2005)). Moreover, positive or negative shocks may lead employers and employees to renegotiate low wages up and high wages down when agents' individual surpluses become negative. The model delivers rich business cycle dynamics of wage distributions and explains why both low wages and high wages are more procyclical than wages in the middle of the distribution.     

Multidimensional life satisfaction,stressful events and social support network of Brazilian children in out‐of‐home care

In 1990, the Child and Adolescents' Statute was passed in Brazil which led to important changes in shelter homes for children who have been removed due to child maltreatment. However very few studies have been conducted on this population since this policy change; the goal of this study is to assess the multidimensional life satisfaction, stressful life events and social network of children living in shelters compared with those living with their families. The sample consists of 155 children ages 7–16 years living in shelters and 142 children living with their families. Data were collected using a structured interview, the Multidimensional Life Satisfaction Scale, the Stressful Life Events Inventory and the Five Field Map. The shelter sub‐sample had many at‐risk characteristics; they also had significantly greater average scores on stressful life events and social support network, while they had lower than average scores on multidimensional life satisfaction. Factors that significantly contributed to predicting life satisfaction were stressful life events, social support network and conflicts with family members. The findings highlight differences between children living in shelters compared to those living with their families; this article also discusses the policy implications of these findings for child welfare practice in Brazil.     

“Like Parent, Like Child?”: The intergenerational transmission of nonmarital childbearing

Data from the 2002 National Survey of Family Growth (N = 11,180) are used to examine the intergenerational transmission of nonmarital childbearing for US men and women. Findings suggest that being born to unmarried parents increases the risk of offspring having a nonmarital first birth, net of various confounding characteristics. This intergenerational link appears to particularly operate via parents’ breaking up before offspring are age 14 and offspring’s young age at first sex. While the link across two generations in nonmarital childbearing is not accounted for by parents’ socioeconomic status (measured as fathers’ education), several mediating factors vary by socioeconomic background. Gender and race/ethnicity also moderate the intergenerational transmission of nonmarital childbearing. This research sheds light on the prevalence of, and process by which, nonmarital childbearing is repeated across generations, which has important implications for long-term social stratification and inequality.     

Still stressful after all these years: a review of lesbians' and bisexual women's minority stress

This article reviews the conceptualization of, and empirical literature on, lesbians' and bisexual women's sexual minority stress. In much of the early research, the experiences of sexual minority women and men were considered together (or women's experiences were inferred from men's), obscuring important differences. There is empirical and theoretical justification to consider the experiences of women and men separately and to develop and evaluate comprehensive models of sexual minority stress for women. Existing conceptualizations of sexual minority stress that include assessment of discrimination, victimization, harassment, concealment, internalized homonegativity may be applied, and perhaps adapted, to facilitate understanding of the unique stressors associated with women's sexual minority status. Future research must include mediators of the relationship between stressors and outcomes such as individual (e.g., coping and resilience) and group (e.g., social support, identification with a sexual minority community) resources. It is also essential to understand what factors may buffer the deleterious effects of these stressors.
