The importance of topology as a tool in preference theory is what motivates this study in which we characterize topologies induced by binary relations and present topological versions of two classical preference representation theorems. We then use our characterizations to construct examples of...

The study investigates the role of credit risk in a continuous time stochastic asset allocation model, since the traditional dynamic framework does not provide credit risk flexibility. The general model of the study extends the traditional dynamic efficiency framework by explicitly deriving the...

In this paper we propose a methodology that we believe improves the effectiveness of several common assumptions underlying Modern Portfolio Theory's dynamic optimization framework. The paper derives a general outline of a stochastic nonlinear-quadratic control for analyzing and solving a...

This paper estimates the effects of friends’ health behaviors, smoking and drinking, on own health behaviors for adolescents while controlling for the effects of correlated unobservables between those friends. Specifically, the effect of friends’ health behaviors is identified by comparing...

This paper examines the demographic pattern of friendship links among youth and the impact of those patterns on own educational outcomes using the friendship network data in the Add Health. We develop and estimate a reduced form matching model to predict friendship link formation and identify...

The Indian textiles industry is now at the crossroads with the phasing out of quota regime that prevailed under the Multi-Fiber Agreement (MFA) until the end of 2004. In the face of a full integration of the textiles sector in the WTO, maintaining and enhancing productive efficiency is a...

We address the problem of input aggregation in DEA models within a broader framework and provide a direct link between input aggregation in DEA on the one hand and the test of parameter restrictions implied by input aggregation in an explicitly specified production function on the other. We show...

Using the non parametric approach of Data Envelopment Analysis (DEA) this paper examines firm’s heterogeneity in the Indian pharmaceutical industry by measuring their input and output efficiencies for the period 1991 to 2005. The analysis establishes that even though firms have been able to...

In this paper we use the nonparametric approach of Data Envelopment Analysis (DEA) to obtain Pareto-Koopmans measures of technical efficiency of individual states in India over the years 1970-71 through 2000-01 in a multi-output, multi-input model of agricultural production. The Pareto-Koopmans...

In the present study we evaluate the overall cost efficiency of a network of branches of a single large public sector bank in India within the city of Calcutta using the data for the year 2002. Our objective is to determine the optimal number of branches within a postal district that could...
