Recently there has been a growing tendency to impose curvature, but not monotonicity, on specifications of technology. But regularity requires satisfaction of both curvature and monotonicity conditions. Without both satisfied, the second order conditions for optimizing behavior fail and duality...

We estimate the generalized McFadden (generalized quadratic) production function by GMM for a manufacturing firm that uses risky monetary assets among its inputs and for a bank that produces risky monetary assets as outputs. We impose curvature globally and monotonicity at a point, as is the...

This cumulative working paper contains the unified joint research completed so far on monetary aggregation under risk, including the extension of index number theory needed to incorporate adjustments for risk into the rate structure, experiments on tracking ability of the unadjusted index, and...

This is the FINAL draft of this paper reporting the results of a long ongoing competition. The paper now is forthcoming in the Journal of Econometrics. This final version replaces the earlier draft that was also in this archive. Interest has been growing in testing for nonlinearity or chaos in...

This paper surveys both the theoretical and empirical economics literatures on nonlinearity, complex dynamics, and chaos. Unlike earlier survey papers, this one is written for professional researchers in the area and assumes relevant mathematical background. Unsolved problems and unresolved...

The following highly-cited research monograph, although widely available in libraries, is now out of print: William A. Barnett, Consumer Demand and Labor Supply, North Holland, Amsterdam, 1981. In case you do not have access to the printed book, I have scanned it and put it online below. Since...

Fellows of the Journal of Econometrics are invited to publish personal opinions regarding the field of econometrics in that journal. This paper is a statement of my personal opinion about the potential role of the World Wide Web in improving data quality and availability in economics. The paper...

In specifications of tastes and technology, econometricians often impose curvature globally, but monotonicity only locally or not at all. In fact monotonicity rarely is even mentioned in that literature. But without satisfaction of both curvature and monotonicity, the second order conditions for...

Diewert's "superlative" index numbers, defined to be exact for second order aggregator functions, unify index number theory with aggregation theory, but have been difficult to identify. We present a new approach to finding elements of this class. This new approach, related to that advocated by...
