Information Disclosure as Environmental Regulation: A Theoretical Analysis

Governments around the world are beginning to embrace a new form of environmental regulation – mandatory disclosure of information. While information disclosure programs appear to have an impact on subsequent firm behavior – often resulting in lower levels of pollution – little is known about the costs and benefits of these programs and whether or not they enhance social welfare. This paper presents a simple bargaining model where mandatory information disclosure is used to overcome a lack of information on the part of the public. We characterize the conditions under which information disclosure will lead to a reduction in emissions, and ultimately, the conditions under which it will enhance social welfare. Several extensions of the model are briefly explored, including the effect of two sources of pollution – only one of which is subject to information disclosure. This paper was prepared while V. Santhakumar was a Visiting Scholar at the Vanderbilt Center for Environmental Management Studies, Vanderbilt University.     

A brief study of age specific birth proportions,Japan and Singapore

The suitability of age-specific birth proportions (ASBP), or percentage distribution of births, as a rough and ready index of fertility change was analyzed by establishing a theoretical framework for its limitations and uses. The discussion suggested that the utility of ASBP as an indicator of fertility change depends on the characteristics and behavior of the population being considered. The concept was then empirically applied to birth trends in Japan and Singapore for 2 different time periods. Analysis suggested that ASBP trends in Japan reflected changes in age-specific fertility rates relative to general fertility rate as well as trends in parity distribution. The Singapore analysis was more complicated, raising different issues. As very limited empirical work has been done on ASBPs, the utility of ASBPs as an indicator of fertility change cannot be definitely ascertained. It was suggested however that ASBP trends may be applicable in countries where the age distribution of fertile-aged women is fairly stable. More empirical research should be done on ASBP trends in other countries, the behavior of A matrix as discussed in this paper, and useful empirical relationship of ASBP with other fertility measures.     

Exact finite sample properties of double k-class estimators in simultaneous equations

In our earlier paper [Srivastava, Agnihotri and Dwivedi (1980)] the dominance of double k-class over k-class with respect to exact mean squared error matrix criteria is established. It is observed that given a member of k-class, one can pick up a member of double k-class that will provide an improved estimator of the coefficients. This result prompted us to study the exact finite sample properties of the double k-class estimator. For this, we have considered a structural equation containing two endogenous variables and have investigated the properties of double k-class estimators of the coefficients of explanatory endogenous variables assuming characterizing scalars to be non-stochastic.     

A multilevel, identity-based approach to leadership development

A frontier of leadership development is examined involving the respective roles of levels-of-analysis and identity in constructing an integrated development system. An approach is described in which individual and relational leadership identities are the focus of developmental efforts at lower organizational levels (e.g., individual contributor and first-level supervisor) but collective identities become the focus at higher levels (e.g., general manager and above). The separate areas of levels-of-analysis and leader identities are first discussed in terms of their respective relevance to leadership development. These are then discussed jointly in elaborating on a proposed development approach that integrates across organizational levels as well as levels of development (i.e., leader development and leadership development). In developing collective leadership identities, processes that involve participants in engaging across boundaries (functional, hierarchical, geographical) are recommended.     

Means of livelihood of city populations: a livelihood classification of the cities in India

Indian censuses provide useful data on livelihood. These data give a picture of the distribution of population deriving their living from different economic activities. According to the 1951 census, 73 cities in the country had a population over 1 lakh. These cities were, more or less, evenly distributed in the different States of the Union. Of the populations in these cities combined, nearly 40% derived its livelihood from the services and miscellaneous sources, approximately 1/4 from production other than cultivation, 1/4 from commerce, and the remaining few from transport and agriculture. These averages were fairly similar for large and small cities. Of the 32 largest cities which showed predominance of their population in 1 or more livelihood, there were about 10 in industrial-manufacturing, 6 in commerce, 9 in transport, and 10 in services. 2 of the 3 port cities, Bombay and Madras, were broad-based in employment while Calcutta was predominant in commerce. There was little uniformity in the livelihood patterns of capital cities.     

Dynamic effects of externalities,optimal saving and economic growth

Conclusion Recognizing the fact that provision of mixed public goods can result in both consumption externalities of the Samuelsonian variety as well as production externalities we set out to extend the earlier results of Rao and Kalpagam (1977) on the effect of public goods on economic growth. In so doing, we considered three standard specifications of production externalities and enlarged the concept of consumption displacement. Our basic conclusion is that the results of our earlier paper remain valid under the more general conditions set out in this paper.     

Recovering Hicksian Consumer Surplus within a Collective Model: Hausman's Method for the Household

The purpose of this paper is to describe the implications of the collective model of household behavior for the methods used to estimate the economic value of non-marketed environmental resources. After demonstrating how the separability restrictions inherent in the collective model allow individual preference and household income allocation choices to be distinguished, the paper demonstrates how the framework can be used to recover Hicksian consumer surplus. An algebraic example is used to illustrate how the framework can be used in valuing environmental resources.
