Gerontological social workers' perceived efficacy for influencing client outcomes

Using a sample of practitioners (n = 269) from the 2004 National Study of Licensed Social Workers, this article employs a quality assurance structure-process-outcome model to examine factors at the practitioner, workplace, and service delivery levels that influence the perceived efficacy of licensed gerontological social workers to affect client outcomes in the context of a highly challenging health care environment. A regression model accounted for 33.9% of the variance (adjusted R (2) = .291) in perceived efficacy with 3 aspects of service delivery satisfaction having significant effects: ability to address complex/chronic care, to influence the design of services, and to help clients navigate the system.     

Equilibrium Wage Dispersion with Worker and Employer Heterogeneity

We construct and estimate an equilibrium search model with on–the–job–search. Firms make take–it–or–leave–it wage offers to workers conditional on their characteristics and they can respond to the outside job offers received by their employees. Unobserved worker productive heterogeneity is introduced in the form of cross–worker differences in a “competence” parameter. On the other side of the market, firms also are heterogeneous with respect to their marginal productivity of labor. The model delivers a theory of steady–state wage dispersion driven by heterogenous worker abilities and firm productivities, as well as by matching frictions. The structural model is estimated using matched employer and employee French panel data. The exogenous distributions of worker and firm heterogeneity components are nonparametrically estimated. We use this structural estimation to provide a decomposition of cross–employee wage variance. We find that the share of the cross–sectional wage variance that is explained by person effects varies across skill groups. Specifically, this share lies close to 40% for high–skilled white collars, and quickly decreases to 0% as the observed skill level decreases. The contribution of market imperfections to wage dispersion is typically around 50%.     

Knocking on Academia's Doors: An Inquiry into the Early Careers of Doctors in Life Sciences

The early careers of French doctors in life sciences are characterized by the importance of temporary jobs. While most young Ph.D. researchers wish to obtain a job in the French academic sector (which grants them, among other things, lifetime employment), few of them manage to achieve this objective immediately after completing their Ph.D. A majority of young doctors have to wait for a period of time before they find stable employment in the academic sector. In the meantime, they usually find temporary research jobs. Two main types of short–term jobs can be distinguished: fixed–term research contracts (in most cases in a French public laboratory) and post–doctoral positions (temporary research jobs in a foreign country). The aim of this paper is to determine whether these different types of temporary jobs have different consequences on the careers of Ph.D. researchers. We first discuss from a theoretical perspective the impact of choosing ‘post–doc’ research rather than a job on a fixed–term contract. Then, after dealing with selection biases that affect the access to these temporary jobs, we will use survival data analysis to estimate the impact of both types of temporary positions on the probability of entering the academic sector. The analysis is based on a database on the early careers of 800 young French doctors in life sciences. The main results include the following findings: the probability of a Ph.D. researcher finding stable employment is higher if he has held a post–doc position than if he has held a fixed–term contract. This result holds for both the private and public sectors. However, careers in the private sector are also affected by long–term choices, such as the decision to undertake Ph.D. research in partnership with a firm.     

Latent Separability: Grouping Goods without Weak Separability

This paper develops a new concept of separability with overlapping groups—latent separability. This is shown to provide a useful empirical and theoretical framework for investigating the grouping of goods and prices. It is a generalization of weak separability in which goods are allowed to enter more than one group and where the composition of groups is identified by the choice of group specific exclusive goods. Latent separability is shown to be equivalent to weak separability in latent rather than purchased goods and provides a relationship between separability and household production theory. For the popular class of linear, almost ideal and translog demand models and their generalizations, we provide a method for choosing the number of homothetic separable groups. A detailed method for exploring the composition of the separable groups is also presented. These methods are applied to a long time series of British individual household data on the consumption of twenty two nondurable and service goods.     

Integrating Knowledge through Information Trading: Examining the Relationship between Boundary Spanning Communication and Individual Performance*

With the global penetration of Internet technologies, individuals may now cross organizational boundaries to communicate efficiently with others regardless of time and space. Thus, when looking for help in solving work tasks, knowledge workers may just as easily contact individuals in rival firms across the globe as a coworker sitting at the next desk. As a result, management faces questions such as (1) How should firms manage employees' knowledge‐sourcing activities when they span both intra‐organizational and extra‐organizational boundaries, and (2) What is the relationship between different knowledge‐sourcing activities and individual performance? Grounded in the knowledge‐based view of the firm, we investigate these questions using data from Europe's largest information technology (IT) services and management consulting company. Our results provide evidence that organizations should support boundary spanning and knowledge sourcing from both internal and external sources. Results suggest (1) a positive relationship between boundary spanning communication and creativity and general performance, and (2) a negative relationship between a reliance on colocated coworkers as knowledge sources and creativity.
