We explore why some firms in the extractive industries disclose mineral reserve quantum in their annual reports and others do not. We propose that the firms' reserve disclosure policies are a function of the extent of information asymmetries, as well as information production, litigation and proprietary costs. More specifically, we propose that a firm's decisions to disclose reserves in the annual report are a function of the stage of the firm's operations, use of project financing, and the cost of measuring reserves. Empirical tests are confirmatory. 相似文献

Ponds,Power and Institutions: The Everyday Governance of Accessing Urban Water Bodies in a Small Bengali City 下载免费PDF全文
Natasha Cornea Anna Zimmer René Véron 《International journal of urban and regional research》2016,40(2):395-409
While researchers in the growing field of urban political ecology have given significant attention to the fragmented hydroscape that characterizes access to drinking water in the global South, so far the (re)production of other urban waters and its related power relations have been underexplored. This article seeks to contribute to filling this gap by exploring the everyday negotiations over access to urban water bodies, in particular ponds. These are understood as a composite resource that is simultaneously water, land and public space. This analysis draws on a case study from a small city in West Bengal, India, and is based primarily on data from open interviews with different actors with a stake in urban ponds. The article demonstrates that in a context of ambiguity of the statutory governance regime and fragmented control, the (re)production of the pondscape is embedded within complex relationships of power whereby social marginalization can be offset at least momentarily by local institutions such as neighbourhood clubs and political parties. 相似文献

Although evidence of a link between socioeconomic status and child health has been researched extensively, much less attention
has been devoted to studying the link between child health and cognitive development. This paper seeks to determine whether
early childhood illnesses and poverty significantly impede cognitive development. The empirical model attempts to control
for observed and unobserved heterogeneity through the use of panel data models. Results indicate that a child’s cognitive
development is not directly related to health problems acquired after birth or socioeconomic standing. Rather, cognitive development
is primarily influenced by unobserved child- and family-specific factors that happen to be correlated with health and socioeconomic
status. On the other hand, birth weight appears to affect cognitive performance later in childhood, even after taking unobserved
heterogeneity into account. 相似文献

Taylor (1992) argues that accounting policy choices in any year are not assessed independently of policy choices adopted in previous years. This independence assumption is a maintained hypothesis of Anderson and Zimmer (1992). Although Taylor acknowledges that our results remain robust to his suggested adjustments for non-independence, we argue in this reply that such adjustments are unnecessary because temporal independence of accounting policy choices is consistent with the implications of costly contracting between the firm and its claimholders. We develop the arguments that (1) accounting choices are temporally independent and our research design is therefore, appropriate (2) to the extent that there is an independence problem of the type proposed by Taylor (1992) it also applies to cross-sectional studies of accounting policy choice. 相似文献

The purpose of this paper is to analyze determinants of the decision to self-report health impairments that limit or prevent work. Its particular focus is on joint reporting behavior by married couples, with a view toward potential interdependence of spouses' reporting decisions. The model is based on a large sample of married couples taken from the 1990 Public Use Microdata Sample of the U.S. Census. Empirical analysis is based on a simultaneous probit model of spouses' reports. Results of the analysis show evidence of an association between spouses' reports, after controlling for important background variables. The extent of association appears to be more pronounced among low earners and among older wives. 相似文献

This paper surveys trust deeds supporting listed public debt issues by Australian industrial and commercial companies. It provides evidence on the restrictive covenants and the accounting rules negotiated therein. The survey indicates cross-sectional variation in the covenants/rules which is related to the nature of the debt. The paper also compares the negotiated rules with mandated accounting standards. As in the U.S. the effect of the negotiated accounting rules is, generally, to reduce management's ability to relax constrictive covenants. 相似文献

This article is an empirical analysis of decisions by judges regarding requests by individuals for disability benefits. Applicants for disability benefits who are twice denied through the normal process can appeal to one of the Social Security Administration’s administrative law judges, who hold appointed positions. The data for this study are taken from decisions made by approximately 1000 judges for cases heard from 2010 through 2012. Using each judge as a unit of observation, the data reveal the number of cases heard and the number of approvals granted. We augmented the data with additional information on the presiding judge, and with data from the state in which the court resides. The purpose of the study is to determine whether a simple model can explain, first, the volume of decisions rendered at the judge level and, second, the proportion of approvals. Results indicate that the volume of decisions can be explained in part by the judge’s recent record of leniency. Evidence also supports the hypothesis that approval outcomes depend on judges’ professional tenure and economic factors in the state of jurisdiction. 相似文献
