Abstract: In this paper, we investigate the association of employee relations with the occurrence of onset of financial distress. We argue that if adverse economic conditions arise, firms that have maintained good employee relations will be more effective in obtaining temporary labor concessions. As a result, firms with good employee relations, to the extent they are dependent on labor in the conduct of business operations, should be more likely to avoid the onset of future financial distress. The empirical findings we document support this prior. 相似文献

Abstract: This paper conducts a UK test of a version of the Ohlson (1995) model. We should only expect abnormal earnings to revert to zero if the book value of assets is economically meaningful. In this paper we make use of the property revaluations common in UK accounts, but estimate other asset values and earnings in inflation‐adjusted terms. This, we argue, gives rise to estimates of abnormal earnings that can reasonably be expected to revert to zero. We then test this modified model on UK data using the Dechow, Hutton and Sloan (1999) method. In line with the predictions of the Ohlson model, we find that these modified abnormal earnings appear to mean revert, and that a first order autoregressive process is sufficient to capture the persistence of UK real abnormal earnings. The modified abnormal earnings model in general predicts one year ahead earnings more successfully than an unmodified model. Furthermore, for much of the sample period, one year ahead predictions of abnormal earnings are better for the real model during periods of higher inflation. The undervaluation problem found in prior studies appears to be replaced with an overvaluation problem in the real model which is more acute during periods of high inflation. Last, we show that an estimate of the model based upon an industry level specification appears to perform no better than a market‐wide specification of the model. 相似文献

Using original archival sources, this article traces the allocation of vehicles by the Soviet economy and shows the complicated reality of the system’s operation. ‘Planned’ distribution was anything but orderly as decrees overturned quarterly plans, wholesalers ignored planning instructions by keeping vehicles for themselves or redirecting them to others, and the producer intervened through its control of the planning ‘aftermarket’. Existing stocks of vehicles were redistributed by administrative mobilizations that were resisted and thwarted by those losing vehicles. Behind the scenes, ‘grey’ markets reallocated used vehicles. 相似文献

High altitude spruce fir forests are typical around the world and are often subjected to multiple forms of recreational use. In this paper, we use household and recreation group data for a spruce fir forest high in the Appalachian Mountains of the U. S. to evaluate the benefits from forest protection (i. e., from improving the forest condition). Our benefits estimation procedures use the referendum-type, contingent valuation (CV) approach of Cameron (1988). We modify the usual practice of obtaining a single willingness-to-pay (WTP) value by using alternative questionnaire scenarios and conducting tests to examine i) household and recreation group value sensitivity to forest condition, and ii) recreation group differences in WTP for forest protection. A first sample of southeastern U. S. households was asked to value a forest protection program for a spruce-fir forest showing no impact from insect disturbance or atmospheric deposition. The second sample was asked to value a protection program for a forest already experiencing impact from insect infestation and air pollution. Logit analysis of the two samples revealed no statistically significant difference in household WTP between the two forest protection programs. Further analysis indicated that consumptive forest users (i. e., hunters and anglers) held forest protection values that were sensitive to a change forest condition, while nonconsumptive forest users (i. e., campers and hikers) held values that were insensitive to the same condition change. Recreation group comparisons revealed that consumptive forest users also held lower values for forest protection than nonconsumptive recreationists. These results demonstrate the importance of estimating public values for forest protection in terms of heterogeneous groups rather than as a homogeneous whole. 相似文献

Highway infrastructure planning is most often oriented toward assessing and maintaining physical inventories but it is often the lack of social knowledge about how people perceive, value and use a transportation system that generates the greatest user conflict and mistrust of public agency behavior. Using results from a 2001 statewide survey of Alaska residents, this paper presents a methodology for examining highway systems as a collection of intrinsic highway qualities and special places that provide a spectrum of highway experience opportunities. The concept of a highway experience opportunity spectrum is described and a number of potential dimensions for creating experience opportunity classes are suggested. With knowledge of spatial locations of intrinsic highway qualities, transportation planners can make informed choices to maintain or alter the set of highway experience opportunities associated with a highway system. 相似文献

Subsistence gardening continues to provide a meaningful way of life on the land for many peoples around the world. Those who seek to ‘help’ indigenous peoples, however, regardless of their motives, techniques, technologies, beliefs, or good intent, invariably interfere with and often destroy traditional ways of life. The interveners reduce the future prospects for those who do have skills and knowledge necessary to wrest a living from working the soil. The Nvhaal speaking people in Southwest Tanna, Vanuatu represent a case in point, for they have been subjected to so-called ‘improvements’ deriving from geological exploration, agricultural innovation, enhanced economic trade, exploitation of an export crop such as kava, improved health care, tourism, politicians, education, and Christian religions. As a result, lifestyles, skills and specialized knowledge bases are eroded, thereby endangering the long-term survival of these and by generalization, other indigenous people. 相似文献

This article proposes a dynamic vector GARCH model for the estimation of time-varying betas. The model allows the conditional variances and the conditional covariance between individual portfolio returns and market portfolio returns to respond asymmetrically to past innovations depending on their sign. Covariances tend to be higher during market declines. There is substantial time variation in betas but the evidence on beta asymmetry is mixed. Specifically, in 50% of the cases betas are higher during market declines and for the remaining 50% the opposite is true. A time series analysis of estimated time varying betas reveals that they follow stationary mean-reverting processes. The average degree of persistence is approximately four days. It is also found that the static market model overstates non-market or, unsystematic risk by more than 10%. On the basis of an array of diagnostics it is confirmed that the vector GARCH model provides a richer framework for the analysis of the dynamics of systematic risk. 相似文献
