    An analytic model of the food consumption behavior of health-conscious individuals
    Kambhampaty, S. Murthy (Virginia Tech, 1994-05-05)
    Evidence of changing patterns of food consumption behavior is presented. Previous attempts at explaining these changes are critically reviewed and the need for an alternate approach is identified. A model of consumer behavior in which utility from food consumption is maximized subject to outlay for foods and limits on the consumption of fat, cholesterol, sodium, and/or other food components is proposed. This model yields a system of demands that are functions of prices and outlay as well as the composition of food and limits on the consumption of these components. The structure of this model is examined and restrictions on consumer food demands are derived. The derivation of individual demands based on the proposed model is demonstrated using a specific indirect utility function. Tests of the joint hypotheses that fat or cholesterol consumption determines food demand are defined. The computation of aggregate food demand elasticities with respect to changes in prices and changes in attributes such as fat or cholesterol consumption is demonstrated. Data necessary for estimating the parameters of the model and testing hypotheses are identified. The model proposed in this study allows tests of the hypothesis that food demands are not affected by food composition as well as measurement of these effects

    Effects of Virginia Coalfield Employment Enhancement Tax Credit Legislation
    Zipper, Carl E.; Kambhampaty, S. Murthy (Virginia Tech. Virginia Center for Coal and Energy Research., 1996-03)
    Coal mining is the major industry in Virginia's far southwestern counties. Coal transportation supports employment in other parts of the state. In 1995, the Virginia General Assembly passed, and the Governor signed, legislation establishing the Virginia Coalfield Employment Enhancement Tax Credit. This tax credit applies to coal produced from mines located within the state's borders. The tax credit is intended as a means of maintaining coal-related employment in the coalfield counties and other parts of the state. The Virginia Coal and Energy Commission is considering proposals that would modify the current tax credit. The current legislation establishes a production tax credit of $0.25 per ton for surface-mined coal, $0.60 for coal produced in deep mines with seam thicknesses under 33 inches, and $0.50 per ton for other deep-mined coal. The current tax credit will be available to coal producers with a three-year delay, and only if the state runs a revenue surplus which exceeds projections during the intervening fiscal year. The Coal and Energy Commission has voted to recommend removal of the revenue surplus contingency and three year-delay provisions from the current legislation. This report contains results of a study of the Coalfield Employment Enhancement Tax Credit's effect on export coal businesses at the Port of Hampton Roads. The study addresses this topic within the context of the tax credit's effect on the state as a whole. The study also addresses the effects of alternative tax credits under consideration by the Coal and Energy Commission.

    A method of evaluating the impact of economic change on the services of local governments
    Kambhampaty, S. Murthy (Virginia Tech, 1990-02-05)
    This study seeks a method of evaluating the local impact of changing economic conditions (such as employment, per capita income, et cetera). Specifically, measures of the impact of changing economic conditions on the services of local governments will be formulated. These measures provide a means for comparing the impact of a project (or of alternative projects) to conditions that would prevail in its (their) absence. The data used is drawn from the Virginia Impact Projection (VIP) Model in the form of statistically derived equations representing the relationships for eleven different categories of public services. The analytical framework was developed based on theories of public decision-making, public finance, and local government expenditures and services. This framework was used to analyze the per capita expenditure relationships (functions) to obtain the information required in formulating the impact measures. For individual categories of services, a SERVICE VALUE INDEX was devised to indicate changes (including shifts) in the demand for the services, and the level of provision thereof. The NET PUBLIC SERVICE BENEFIT is a measure of the overall increase (decline) in public services provision, and balances the change in levels of service on the individual categories against each other. This measure reflects the net benefits derived by the consumer-voter following her/his reallocation of expenditures given the new cost conditions, budget constraints, et cetera, as a consequence of the project.
