Private grazing fees differ substantially and systematically across states in the West. In contrast, federal policy establishes the same grazing fee on federal lands, regardless of location. We analyze locational differences in private grazing fees with an econometric model. Differences in...

Any demand equation satisfying Lau’s (1982) Fundamental Theorem of Exact Aggregation and 0° homogeneity in prices and income will have a Gorman (1981) functional form for each income term. This property does not depend on symmetry or adding up. The implications of this result are illustrated...

Are global temperatures on a warming trend? It is difficult to be certain about trends when there is so much variation in the data and very high correlation from year to year. We investigate the question using statistical time series methods. Our analysis shows that the upward movement over the...

This paper investigates empirically the Balassa-Samuelson hypothesis (BSH) using annual data over 1970-2008 from 33 countries grouped into developed and developing countries. The innovative feature of our study is that we introduce a new approach for classifying traded and nontraded industries....

Advances in data collection and storage have tremendously increased the presence of functional data, whose graphical representations are curves, images or shapes. As a new area of Statistics, functional data analysis extends existing methodologies and theories from the fields of functional...

A significant role for hypothesis testing in econometrics involves diagnostic checking. When checking the adequacy of a chosen model, researchers typically employ a range of diagnostic tests, each of which is designed to detect a particular form of model inadequacy. A major problem is how best...

In this paper we investigate long-run optimal social security and public health and their effects on fertility, longevity, capital intensity, output per worker and welfare in a dynastic model with altruistic bequests. Under empirically plausible conditions, social security and public health...

This paper provides an empirical analysis of the role of intergovernmental relations on a country's effort to enforce the objectives of an international environmental agreement on an open access resource. Intergovernmental interaction allows signatory countries to observe compliance behavior of...

This paper makes methodological and empirical contributions to the study of HIV awareness, knowledge, incidence and safe sex practice in the context of Botswana, one of the most HIV prone countries in the world. While the focus is on Botswana, the paper presents comparable evidence from India to...
