Genuine savings is a conceptually valid one‐sided indicator as to whether Australia is on a weak sustainability path (negative GS would warn that current welfare is unsustainable). The World Bank's adjusted net savings (ANS) data summarise the available evidence, and by this indicator Australia is muddling along, at best. ANS misses some important pieces of the picture – net depletion of water, soil and biodiversity, and most kinds of pollution damage – and thus overstates Australia's genuine savings performance. Weak sustainability can be promoted by getting the prices right, and piecemeal efforts are underway via regulatory approaches and resource/environmental markets of various kinds. Nevertheless, particular resource problems – habitat conservation, biodiversity, climate change and dryland salinity – are likely to also require strong sustainability approaches. A sustainable future involves pushing weak sustainability as far as the body politic permits, invoking precautionary instruments for specific resource crises, and nurturing policy processes that encourage the consensus‐building that will be necessary to get it done. 相似文献

This study examines the accrual anomaly under the framework of the Campbell [Campbell, J.Y. (1991). A variance decomposition for stock returns. Economic Journal 101 (405), 157-179.] model. The Campbell (1991) model shows that realized asset returns are a joint function of 1) expected returns, 2) revisions in market expected future returns (i.e., return news), and 3) revisions in market expected future cash flows (i.e., cash flow news). The current study adopts the Easton [Easton, P. (2004). PE ratios, PEG ratios, and estimating the implied expected rate of return on equity capital. The Accounting Review 79 (1), 73-96.] model to estimate proxies for expected returns, return news, and cash flow news. The results show that firms with low accruals have lower expected returns than firms with high accruals, which is contradictory to prior research that argues that firms with low accruals are more risky. However, investors underestimate (overestimate) future earnings growth, a proxy for cash flow growth, for low (high) accrual firms. Further analysis demonstrates that earnings news (proxy for cash flow news) plays a major role in explaining abnormal returns associated with the accrual anomaly. 相似文献

A multidimensional scale for measuring business ethics: A purification and refinement 总被引:1,自引:0,他引:1
Randall S. Hansen 《Journal of Business Ethics》1992,11(7):523-534
Many researchers in the field of business ethics have attempted to develop methods to determine and evaluate the ethics of a variety of different classes of people, including students, professionals, and mixed samples of students and professionals. Unfortunately, most of these studies were disjunctive, simply adding confusion to an already unfocused area of research. However, Reidenbach and Robin (1988, 1990), have changed this trend by attempting to quantify the various ethical philosophies into a multi-dimensional scale of business ethics. This paper examines the background of the Reidenbach and Robin (1988, 1990) scale — including the authors' findings, empirically tests the scale, and concludes that the scale needs further refinement. A promising result is a model with four dimensions: a broadbased ethical judgment dimension, a deontological judgment dimension, a teleological judgment dimension, and a social contract dimension.Randall S. Hansen is ABD at Florida State University, where his major is marketing and his support area is strategic management. His research interests are directed toward the applied areas of managerial and consumer ethical decision-making as well as strategic issues in social responsibility. He has published in theProceedings of the Academy of Marketing Science, Proceedings of the Southern Marketing Association, andProceedings of the Southern Management Association. 相似文献

We develop a theory of money and credit as competing payment instruments, then put it to work in applications. Agents use cash and credit because the former (latter) is subject to the inflation tax (transaction costs). Frictions that make the choice of payment method interesting also imply equilibrium price dispersion. We derive closed-form solutions for money demand, and show how to simultaneously account for the price-change facts, cash–credit shares in micro data, and money-interest correlations in macro data. The effects of inflation on welfare, price dispersion and markups are discussed, as are nonstationary equilibria with dynamics in the price distribution. 相似文献

Extant studies show that stock returns are abnormally negative before executive option grants and abnormally positive afterward. We find that this return pattern is much weaker since August 29, 2002, when the Securities and Exchange Commission requirement that option grants must be reported within two business days took effect. Furthermore, in those cases in which grants are reported within one day of the grant date, the pattern has completely vanished, but it continues to exist for grants reported with longer lags, and its magnitude tends to increase with the reporting delay. We interpret these findings as evidence that most of the abnormal return pattern around option grants is attributable to backdating of option grant dates. 相似文献

As developed in Muth's “Cities and Housing,” attainment of locational equilibrium within an urban area implies a necessary functional correspondence between wage and price gradients and the compensated price elasticity of demand for housing. In this paper estimates of the rent and wage gradients are utilized to generate price-elasticity estimates via this equilibrium correspondence. The Box-Cox transformation technique is used with data from the metropolitan Chicago area to test for the functional forms of the wage and rent gradients. The optimal maximum-likelihood functional forms for both gradients yield a price-elasticity estimate of ?0.40. 相似文献

The Australian water economy is entering a mature phase characterised by inelastic supply of 'new' water and the need for expensive rehabilitation of aging projects. Thus, the policy focus will turn increasingly toward ways of restraining water demand and reallocating existing supplies. A prima facie case is made that the efficiency loss from current water pricing and allocation policy is significant. After considering the relevant welfare economics theory, the theory of administered prices and marketable property rights and some American proposals for reform, a system of transferable water entitlements is proposed and developed. 相似文献

This study applies three different methods widely used in the literature to track changes in shadow economic activity in Georgia following a drastic tax reform in 2005. The first method is a currency demand approach based on macrolevel data. The second and third methods rely on micro level data from household surveys. Overall, we find evidence that the amount of income underreporting decreased in the years following the reform. The biggest change is observed for households headed by a farmer, followed by ‘other’ types of households where the head does not report any working status. Employed and self‐employed households appear very similar before the tax reform and show minimal adjustment in income reporting in the post‐reform period. Results, however, suggest that much of any difference may have come from increased enforcement efforts rather than rate changes. 相似文献
