Contingent valuation of ill health caused by pollution: testing for context and ordering effects

Contingent valuation is being increasingly used to value episodes of ill health caused by environmental pollution. In contrast to studies that have used contingent valuation to value other types of non-market goods, health episode valuation studies have tended to 1) value several ill health episodes or symptoms in the same survey, and 2) be vague in the survey instrument about the cause of the ill health, how it would be avoided or how the improvement would be paid for. The resulting values are then combined with exposure-response functions to generate economic estimates of health damages from pollution. This study tests whether episode valuation responses are sensitive to two of these design features. In a five-country study using split sample treatments, neither episode ordering nor mention of the cause of the ill health influenced stated willingness to pay to avoid specific ill health episodes.JEL Classification: C42, I12, Q51 Correspondence to: Richard ReadyThis research was supported by the European Unions Environment and Climate Research Programme: Theme 4 - Human Dimensions of Environmental Change (contract no.

The cyclical effects of the Basel II capital requirements

Capital requirements play a key role in the supervision and regulation of banks. The Basel Committee on Banking Supervision is in the process of changing the current framework by introducing risk sensitive capital charges. Some fear that this will unduly increase the volatility of regulatory capital. Furthermore, by limiting the banks’ ability to lend, capital requirements may exacerbate an economic downturn. The paper examines the problem of capital-induced lending cycles and their pro-cyclical effect on the macroeconomy in greater detail. It finds that the capital buffer that banks hold on top of the required minimum capital plays a crucial role in mitigating the impact of the volatility of capital requirements.     

Delineating the anatomy of an entrepreneurial university: the Massachusetts Institute of Technology experience

In many universities, heads, administrators and faculty seek to increase the propensity to engage in commercialization of research activity through the spinoff of new companies. The highly complex mechanism of spinoff generation is typically considered the result of either the characteristics of individuals, organizational policies and structures, organizational culture, or the external environment. Explanations of spinoff activity have in the main focused on only one of these dimensions at a time. In this paper we integrate these four dimensions of academic entrepreneurship to develop a more systemic understanding of spinoff activity at the university level. Using the case of Massachusetts Institute of Technology (MIT), a top spinoff generator in the United States, a systemic analysis is presented. We identify the inter-related factors that have contributed to successful academic entrepreneurship in MIT. We argue that MIT's success is based on the science and engineering resource base at MIT; the quality of research faculty; supporting organizational mechanisms and policies such as MIT's Technology Licensing Office; and the culture within MIT faculty that encourages entrepreneurship. However, to understand why MIT has developed these resources and organizational mechanisms, it is necessary to understand the historical context and emergence of MIT, and in particular the historical mission of the university, the role of key individuals and university leaders in supporting this mission, and the impact of past success at commercialization activity. Finally, we suggest that MIT's success needs to be understood in the context of the local regional environment. We argue that university administrators and academics can learn from the case of MIT, but that efforts at transposing or replicating single elements of MIT's model may only have limited success, given the inter-related nature of the drivers of spinoff activity.     

Privatization and stock market liquidity

This paper shows that share issue privatization (SIP) is a major source of domestic stock market liquidity in 19 developed economies. Particularly, privatization IPOs have a negative effect on the price impact – measured by the ratio of the absolute return on the market index to turnover. This result is robust to the inclusion of controls for other observable and unobservable factors, having also considered the endogenous nature of the decision to privatize.     

When Taxation Changes the Course of the Year: Fiscal‐Year Adjustments and the German Tax Reform of 2000–01*

This paper examines 157 German listed corporations that had the option of changing their fiscal year to achieve a possible tax reduction in connection with the major tax reform of 2000—01. The tax reduction from a change was larger, the larger the expected profits. However, with costs of changing the fiscal year, not all firms that expect a tax reduction from a change may do so. The paper presents empirical evidence that the propensity to change the fiscal year was significantly related to the amount of expected tax savings. This suggests that the corporate tax reduction — in combination with the special German transitory provisions — induced a deadweight loss: corporations incurred a non‐tax cost to avoid a tax cost.     

Stock options and capital structure

We show that value-maximizing CEOs compensated with stock options prefer debt to equity. Our pecking order result does not depend on managerial risk aversion, managerial firm-specific human capital, or asymmetric information. Moreover, our result holds at least weakly regardless of the distribution of firm cash flows and strictly as long as the support of the cash flow distribution is big enough to bring all features of the stock option contract into play with positive probability JEL Classification Numbers: G0, G3 An earlier version of this paper was completed while Page was visiting CERMSEM at Paris 1 and the University of Warwick.

Announcement and Publication Decisions and the Use of Prediction Errors in Cross-Sectional Analysis: Evidence on Seasoned Equity Issues

An important concern for empirical analysis of market responses to public releases of information is whether the voluntary nature of announcement and publication decisions imparts a selectivity bias and, if so, how this bias affects empirical results. Using a database of SEC filings of equity issues, all related Wall Street Journal published announcements are identified. The published announcements are used to classify proposed issues into subsamples with homogeneous information structures. Announcement and WSJ publication decisions are found to be non-random but, for industrial firms, not significantly related to firm size or exchange listing. Coefficients estimated without controlling for selectivity are found not to be significantly biased for either industrial or utility issues. However, for industrial issues, significance levels are considerably lower when selectivity bias is controlled. The hypothesis common to other studies of new issue announcement effects that observations from different information structures can be pooled, with coefficient estimates restricted to be equal across information structures, is rejected. The results have implications for the methods used to study cross-sectional market responses

Deterrence versus intrinsic motivation: Experimental evidence on the determinants of corruptibility

This paper reports on an experiment of corruption that was conducted in two treatments: one with the possibility of detection and one without. It turns out that monitoring reduces corruption through deterrence; at the same time, it destroys the intrinsic motivation for honesty. Thus the net effect on overall corruption is a priori undetermined. We show that the salary level has an influence on corruption through increased opportunity costs of corruption, but fail to find evidence for a ‘payment satisfaction’ effect. Interesting policy conclusions emerge.
