Why is the corporate tax rate lower than the personal tax rate?: The role of new firms

In many OECD countries, statutory corporate tax rates are lower than personal income tax rates. This tax rate difference is often particularly large for small firms. The present paper argues that a reduction of the corporate tax rate below the personal tax rate is an optimal tax policy if there are problems of asymmetric information between investors and firms in the capital market. The reduction of the corporate tax rate below the personal tax rate encourages equity financing and thus mitigates the excessive use of debt financing induced by asymmetric information. Our main theoretical result stands in marked contrast to the traditional view of corporate taxation and corporate finance theory, according to which there is a tax disadvantage to equity financing. More recent empirical evidence on this issue, however, is in line with our result.     

Water accounting in Australia

This paper introduces water accounting as produced by the Australian Bureau of Statistics (ABS). It provides information about the ABS Water Accounts and highlights the many other organisations involved in the provision and use of water related data in Australia. The ABS Water Accounts have built upon previous reports on Australian water resources and the System of Environment and Economic Accounting [UN (United Nations) 2003. Draft Handbook Integrated Environmental and Economic Accounting. Studies in Methods, Series F, No. 61, Rev. 1. United Nations, European Commission, International Monetary Fund, Organisation for Economic Cooperation and Development, World Bank. New York.]. Information from the ABS Water Accounts is presented along with examples of their use in economic analyses designed to inform public debate and government decision-makers.A key feature of the Australian environment is that water is relatively scarce when compared with other inhabited continents. Rainfall displays a high level of spatial and temporal variability and droughts are common. In 2004 an Intergovernmental Agreement on a National Water Initiative (NWI) was reached by Australia's national and eight state and territory governments. The NWI aims to address environmental, economic and social concerns about the current and future state of Australia's water resources. The NWI specifically calls for the preparation of annual water accounts, which clearly indicates the expected usefulness of national and regional water accounts.     

The effect of environmental and social performance on the stock performance of european corporations

This paper examines the effect of sustainability performance of European corporations on their stock performance, measured as the average monthly stock return from 1996 to 2001. The econometric analysis is based on common empirical asset pricing models, particularly on the multifactor model according to Fama and French (1993, Journal of Financial Economics, 33:3–56). The consideration of sustainability performance is two-fold: The average sustainability performance of the industry in which a corporation operates and the relative sustainability performance of a corporation within a given industry. The main result is that the average environmental performance of the industry has a significantly positive influence on the stock performance. In contrast, the average social performance of the industry has a significantly negative influence. The variables of the relative environmental or social performance of a corporation within a given industry have no significant effect on the stock performance. As a by-product, the econometric analysis implies that some results of Fama and French (1993, 1996, The Journal of Finance, LI (1):55–84) regarding the risk factors of the multifactor model need not hold true for different observation periods, for different stock markets, and for the use of single stocks (instead of portfolios).

Pollution abatement with limited enforcement power and citizen suits

Federal environmental laws in the U.S. can be enforced by government agencies or by private parties through citizen suits against polluters. Here, I extend the standard enforcement model to examine the role played by citizen suits. The main results from the paper suggest that in a model with limited enforcement power and citizen suits the regulator fully exercises his enforcement power when the expected penalty from a citizen suit is low, but increases his reliance on citizen suits as the expected penalty rises. Whether an enforcement regime that allows private enforcement is efficient depends not only on the relative costs of private and agency enforcement, but also on the changes in inspection costs that may be caused by private enforcement and the expected penalty from losing a citizen suit. These results suggest that in practice private enforcement may lower social costs as long as relatively inexpensive agency enforcement options, such as administrative proceedings, do not preclude citizen suits.      

Co-ordinated environmental regulation: controlling non-point nitrate pollution while maintaining river flows

Environmental policy often addresses multiple targets, yet much economic analysis of pollution control is based on a single-target objective. In this paper, we present an analysis of policies to control non-point source nitrate pollution in the presence of minimum river flow restrictions. A non-linear bio-physical economic optimisation model of an intensively cultivated Scottish agricultural catchment was constructed. The presence of minimum river flow controls in the catchment was found to reduce nitrogen pollution. However, by themselves, river flow controls were found not to be a cost effective means to reduce non-point pollution. We quantify the improved social welfare from coordinating the environmental regulation of river flows and pollution, and determine the conditions under which such coordination is beneficial. The paper also investigates whether the benefits of such coordination can be sustained under wetter (winter) weather conditions implied by current climate change predictions.     

Children’s health benefits of reducing environmental tobacco smoke exposure: evidence from parents who smoke

This paper uses data from the 1991 National Maternal and Infant Health Survey to estimate propositions derived from a model of intrahousehold allocation, wherein parents engage in a consumption activity (smoking) that produces own utility, while generating environmental tobacco smoke (ETS) that harms their children’s health. We find a statistically significant negative association between sample mothers‘ assessed health of their children and the children’s daily exposures to ETS. Mothers’ average annual willingness-to-pay (WTP) for a 1-hour-per-day reduction in child ETS exposure (about a 17% decrease in daily exposure) is about $150. WTP estimates for respondent mother and child health status further suggest that smoking mothers on average value their child’s health roughly 55% higher than their own health.

Although the U.S. Environmental Protection Agency provided financial support through Grant#R82871601, the research has not been subjected to the Agency’s required peer and policy review and therefore does not necessarily reflect the views of the Agency     

Economic and environmental efficiency using a social accounting matrix

This paper aims to show the utility of the so-called Social Accounting Matrix and Environmental Accounts (SAMEA) for economic and environmental efficiency analysis. The article uses the SAMEA for Spain in 2000, applied to water resources and greenhouse gas emissions. This matrix is used as a central core of a multisectorial model of economic and environmental performance, and it calculates the denominated “domestics SAMEA multipliers” and their decomposition into characteristic, direct, indirect and induced effects. These multipliers show some evaluation of economic and environmental efficiency. Also, we present an application of these multipliers that demonstrates that there is no causal interrelation between those sectors with higher economic backward linkages and those with higher environmental deterioration backward linkages.

Progress along the path: evolving issues in the measurement of genuine saving

More than 10 years since a practical linkage between sustainable development and a measure of national wealth—expanded to include natural and environmental resources—was first posited, the empirical estimation of adjusted net savings, dubbed ‘genuine’ saving, has evolved considerably. In this paper we take stock of both progress achieved and the challenges that remain. We begin by recalling the key points made in Pearce and Atkinson (1993, Ecol Econ 8, 103), which presented the first cross-country estimates of savings rates adjusted to reflect depletion and degradation of the environment. We then briefly summarise the evolution of the theoretical argument linking savings and sustainability. However, the main focus of this paper is an aspect that concerned David Pearce greatly, namely the evolution of the measurement of genuine savings. We identify and consider the empirical evidence with regard to two particular measurement issues: the valuation of exhaustible resources and environmental degradation. Common to the both issues are concerns about measuring changes in national wealth in real world economies.
