Housework and the Wages of Young, Middle-Aged, and Older Workers   总被引:1,自引:0,他引:1  
This article uses samples of young, middle-aged, and older married workers drawn from the Panel Study of Income Dynamics to examine whether the effect of housework time on wages differs among these age groups. Results from OLS, fixed effects, and panel data instrumental variables models show that young and middle-aged wives are the only groups for which the authors find consistent evidence of a housework effect on wages. Each additional hour of housework reduces their wages by 0.1–0.4%. Additionally, the analysis finds evidence that for young workers, housework time is an important determinant of the male/female wage gap. (JEL J16 , J22 , J31 )  相似文献

The available literature on self-initiated expatriates (SIEs) is generally based on the assumption that SIEs are protean in character and manage their careers independently. The current qualitative empirical study offers an alternative to this assumption, using 23 interviews with Western SIEs employed by local organizations in China to examine how and why SIEs target obtaining a labour market fit through career self-management behaviour, particularly in culturally distant career contexts. The assessment of the career self-management behaviour of Western SIEs was undertaken using King's framework (2004). Three approaches to self-management behaviour were identified based on the motivation and outcome expectations of SIEs: labour market entry, employability maintenance and career advancement. The research illustrates the flexible and dynamic nature of career self-management behaviour and reflects individuals' revised career expectations and the employment context of the host country. The findings contribute to the extant theory on SIEs by illustrating emerging means of realizing international careers in cross-cultural career contexts, and the significance of third-party initiatives supporting expatriation facilitated by the Internet and social media.  相似文献

Studies on dynamic managerial capabilities still have a rather theoretical nature, and there is great difficulty in finding a valid, reliable instrument to measure this construct. The present study contributes to solving this problem: It aims to develop and validate a scale to measure dynamic managerial capabilities. In this investigation, we develop a scale for three factors related to dynamic managerial capabilities: human capital, managerial cognition (already described in the literature), and relationship networks. The prominent finding in this research is the factor that is referred to here as relationship networks.  相似文献

We study the business‐cycle behavior of segmented labor markets with flexibility at the margin (e.g., just affecting fixed‐term contracts). We present a matching model with temporary and permanent jobs (i) where there is a gap in the firing costs associated with these types of jobs and (ii) where there are restrictions in the creation and duration of fixed‐term contracts. We show that a labor market with ``flexibility at the margin'' increases the unemployment volatility with respect to one that is fully regulated. This analysis yields new insights into the interpretation of the recent volatility changes witnessed in the OECD area.  相似文献

This article uses both cross‐sectional and longitudinal methods to evaluate the national industrial relations systems of 30 Organisation for Economic Co‐operation and Development (OECD) countries from 1993 to 2005. We adopt a pluralistic view of industrial relations that gives equal weight to efficiency and equity, along with a general systems model consisting of input, process and output. We rank each country in terms of a combined score of efficiency and equity. We find that the 30 OECD countries can be separated into three distinct groups (high on both equity and efficiency; high on efficiency but low on equity; moderate on equity and low on efficiency), and that these groups exhibit considerable stability over time.  相似文献

Estimation of expected return is required for many financial decisions. For example, an estimate for cost of capital is required for capital budgeting and cost of equity estimates are needed for performance evaluation based on measures such as EVA. Estimates for expected return are often based on the Capital Asset Pricing Model (CAPM), which states that expected excess return (expected return minus the risk-free rate) is equal to the asset's sensitivity to the world market portfolio (β) times the risk premium on the “world market portfolio” (the market risk premium). Since the world market portfolio, by definition, contains all assets in the world, it is not observable. As a result, an estimate for expected return is commonly obtained by taking an estimate for β based on some index (as a proxy for the world market portfolio) and an estimate for the market risk premium based on a potentially different index and multiplying them together. In this paper, it is shown that this results in a biased estimate for expected return. This is undesirable since biased estimates lead to misallocation of funds and biased performance measures. It is also shown in this paper that the straightforward procedure suggested by Fama and MacBeth [J. Financ. Econ. 1 (1974) 43] results in an unbiased estimate for expected return. Further from the analysis done, it follows that, for an unbiased estimate, it does not matter what proxy is used, as long as it is used correctly an unbiased estimate for expected return results.  相似文献

Total factor productivity (TFP), factor accumulation, and growth are analysed for a panel of 40 countries in 2001–11. TFP growth and technical inefficiency are estimated using a stochastic frontier model. Environmental variables are found to have an important role in explaining differences in inefficiency across countries. Over 2001–11, the general improvement in technical efficiency of countries is almost outweighed by technological regress. Results indicate that differences in factor accumulation between OECD and emerging economies are more important than differences in TFP change to explain differences in economic growth. Results also indicate negative and significant random shocks for the OECD countries.  相似文献

Aims: Although several therapeutic options are available for chronic immune thrombocytopenic purpura (cITP), little is known about the treatment of cITP in Brazil.

Materials and methods: A multi-center, retrospective chart review, observational study was designed to describe the treatment patterns, clinical burden, resources use, and associated costs for adult patients diagnosed with cITP and treated in public and private institutions in Brazil. Patient charts were screened in reverse chronological order based on their last visit post January 1, 2012. (All costs were calculated using 1.00 USD?=?3.9571 BRL, from February 2016.)

Results: Of 340 patient charts screened, 50 patients were eligible for inclusion in the study. Single-drug therapy (prednisone, dexamethasone, or dapsone) was the most commonly used treatment, followed by combination therapies (azathioprine?+?prednisone, azathioprine?+?prednisone?+?danazol, and prednisone?+?dapsone). Splenectomy was performed in 22% of patients after at least first-line treatment. Platelet count and number of bleeding episodes at diagnosis were 31,561.1/mm3 (SD?=?±26,396.1) and 40 episodes, respectively; in first-line, 92,631.1/mm3 (SD?=?±79,955.3) and 19 episodes, respectively; in second-line, 96,950.0/mm3 (SD?=?±76,476.4) and 17 episodes, respectively. Private system patients had a higher median cost compared to public system patients (USD 17.49/month, range?=?0–2,020.77 vs USD 9.51/month, range?=?0–192.64, respectively).

Limitations: This study does not allow conclusions for causal explanations due to the cohort study design, and treatment patterns represent only the practices of physicians who have agreed to participate in the study.

Conclusions: The data indicate that available therapeutic strategies for second- and third-line therapies appear to be limited.  相似文献

This research theorizes that sellers of durable goods can utilize inferences about the buyer's willingness to pay based not only on her decision to trade in the old good but also on its characteristics. We find empirical support for this theory using transaction data for new car purchases. The results support the notion that dealers infer a higher willingness to pay and charge higher prices to consumers who trade in a used vehicle than to those who do not. We also find that dealers charge even higher prices to those consumers who trade in used cars that are similar to the new one.  相似文献

Encouraging and facilitating employee voice among frontline employees is important in organisations to draw out problems and issues that can potentially be addressed and mitigated by organisational policies and practices. Using Conservation of Resources theory, this study focuses on paramedics and the formal and informal voice mechanisms used to safeguard their well-being. We observe that paramedics are often unwilling to use formal support mechanisms, at least in the first instance immediately following exposure to a traumatic event, but they see informal peer-to-peer voice as critical in preventing resource loss and regaining resources for subsequent call-outs. We also found that without an awareness of the importance of this support mechanism, changes in work organisation can unintentionally and unknowingly limit their capacity to engage in this form of support. Losing peer-to-peer voice can lead to the build-up of stress that could otherwise be mitigated, resulting in diminished well-being.  相似文献
