In this paper we examine a range of issues related to the analysis of health surveillance data when it is spatially-referenced. The importance of considering alarm functions derived from likelihood or Bayesian models is stressed. In addition, we focus on some new developments in predictive...

<title>Abstract</title> This article explores the homology between states of affect as represented in literary texts by Emerson, Poe, and Alcott, and the stages of the business cycle of 1832--1842. It argues that recurrent cycles of mania, panic, and depression served to habituate Americans to the business...

This paper examines the effects of the use of increasingly-popular phytosanitary regulations on production costs, and output and factor trade flows. The case addressed is that of the European regulation of maximum chemical residues in cigarettes manufactured with tobacco containing maleic...

Slippage rates for corn and wheat are estimated using a simultaneous system explaining per-acre yields, input usage, technical change, and levels of participation in government programs. Soybeans are included due to cross-compliance requirements and because they substitute for corn in...

The importance of heterogenous land quality in determining slippage on corn production in North Carolina is quantitatively analyzed. Field-level analysis controls for the influence of land productivity from other factors to determine the significance of the land decisions on slippage. Results...

Field level distributions of land quality are used to explain diversion decisions under U.S. commodity programs. Regression results for North Carolina indicate that differences in the yield potential of soils may influence the opportunity costs of land diversions. These effects increase with...

A procedure is presented to calculate welfare consequences of chemical regulation from demand curves when input applications are unobserved, and is applied to maleic hydrazide and tobacco. The relationship between chemical residues and weather variables and prices is estimated, and from this the...
