Farm families with incomes below the poverty line are far less likely than wealthier farmers to receive farm support payments. Using data from the 1989–2004 Current Population Survey, we find that poor farm families are also not participating in other assistance programs. Controlling for other factors, eligible farm families have substantially lower participation rates in the Food Stamp Program and in Medicaid than eligible nonfarm families. Removing farm safety net program payments would increase the number of farmers eligible for these programs but, in the absence of behavioral changes, would only lead to small increases in the number of recipients. 相似文献

We propose a two-stage procedure to estimate conditional beta pricing models that allows for flexibility in the dynamics of asset betas and market prices of risk (MPR). First, conditional betas are estimated nonparametrically for each asset and period using the time-series of previous data. Then, time-varying MPR are estimated from the cross-section of returns and betas. We prove the consistency and asymptotic normality of the estimators. We also perform Monte Carlo simulations for the conditional version of the three-factor model of Fama and French (1993) and show that nonparametrically estimated betas outperform rolling betas under different specifications of beta dynamics. Using return data on the 25 size and book-to-market sorted portfolios, we find that the nonparametric procedure produces a better fit of the three-factor model to the data, less biased estimates of MPR and lower pricing errors than the Fama–MacBeth procedure with betas estimated under several alternative parametric specifications. 相似文献

Roles, role performance, and radical innovation competences 总被引:1,自引:0,他引:1

Despite the importance of radical innovations (RI), few firms have the capability to develop such innovations internally; success is increasingly linked with relationships and networks. However, the way(s) in which relationships and networks support RI is less clear. Successfully launching RIs requires the development of four distinctive competences; discovery, incubation, acceleration and commercialization. This paper examines how networks support the development of RIs, focusing on when and how network partners become involved and how their role performances support the development of the four competences. The study context is the automotive industry, which is heavily dependent upon RI and complex interrelationships. Data were collected through in-depth interviews with network participants involved in developing several RIs. Five task-oriented and three network-oriented roles are uncovered and the performance of these roles supports the development of different competences, with some roles being exclusively connected with particular competences and others supporting several competences. Focusing on role performance offers a useful means for distinguishing between acontextual actors, and the activities and resources they bring. In doing so, the paper enhances understanding of the links between network participants, role performances and the development of RI competences, and identifies a number of important implications for theory and practice. 相似文献

The total cost of employee absence for many employers is high, and the correlation between employee health and disability is clear. This article reviews several challenges employers face in managing employee health and absence in a well-integrated manner. Although such an undertaking is not easy, the additional cost national health care reform may bring makes the interrelationship between employer profitability and employee absence, health and disability more crucial than ever for employers to recognize and manage. 相似文献

Relatively little is understood about factors triggering entrepreneurial behaviour within organizations not driven by profit motives. Governance plays an important role in non‐profits, particularly boards of directors. Integrating resource‐based theory and entrepreneurial orientation research, we examine the influence of non‐profit boards as strategic resources shaping the organization's entrepreneurial orientation and performance. In particular, we focus on the non‐profit board's underlying behavioural orientations, or the extent to which the board is strategic, activist, conservative, and cohesive. Findings from a cross‐sectional survey on arts and culture organizations demonstrate that three of these behavioural orientations impact levels of entrepreneurship occurring within non‐profits. Higher levels of entrepreneurship affect social performance, but not financial performance. 相似文献

This paper seeks to make a contribution to the critical literature on management and, more particularly, to the critique of managerialism. This is achieved via a consideration of the hitherto neglected writing of Simone Weil (1909–43) on management, work and organizations. Following an introduction to this work, attention is focused on Weil's notion of oppression, and detailed consideration is given to the conceptualization of management as a form of oppression. the bulk of the paper elaborates the significance of Weil's work for the critique of contemporary forms of managerialism. In particular, the development of new forms of managerial expertise, and the phenomenon of self-management, are analysed as forms of oppression. It is suggested that Weil offers the basis of a non-relativist post-Marxist form of ethically grounded critique in the field of management studies. 相似文献

Quantifying tax effects under policy foresight 总被引:1,自引:0,他引:1
Shu-Chun Susan Yang 《Journal of Monetary Economics》2005,52(8):1557-1568
Studies of tax effects make the conventional information assumption that changes in period-t taxes become known at t. Legislative lags, however, imply that news arrives before tax changes take place. Under policy foreknowledge, the conventional information structure is therefore misspecified. Simulations of a standard neoclassical growth model suggest that foresight of only one quarter can distort substantially the estimates of tax effects obtained under the no-foresight assumption. Also, it is crucial to model capital and labor taxes separately: anticipated changes in these two tax policies have opposite effects on consumption, investment, labor, and output before policy realization. 相似文献

Our model explores the co‐existence of both cooperative and competitive behaviors in an alliance setting. Specifically, when alliance partners cooperatively choose observable contributions given reported costs, their self‐interested behavior may lead to misreporting of costs related to these contributions. We show that truthful cost reporting by an alliance firm is valuable, thereby establishing that accurate cost reports are a determinant of successful alliance performance. Next we show that an alliance firm's cost reporting behavior may depend on the type of payoffs it receives from alliance, i.e., a share of profit or revenue, and also on the type of relationship between contributions, i.e., whether they are technical substitutes or complements. While we have focussed on highlighting factors which underlie cost misreporting, this study also may serve as a basis for investigating ways to design contracts to diminish the loss an alliance suffers from cost misreporting of the firms, thus increasing the chance that an alliance will be successful.
