Splendide Mendax: False Label Claims about High and Rising Alcohol Content of Wine 31
Alston, Julian M.; Fuller, Kate B.; Lapsley, James T.; Soleas, George; Tumber, Kabir P..
Many economists and others are interested in the phenomenon of rising alcohol content of wine and its potential causes. Has the alcohol content of wine risen—and if so, by how much, where, and when? What roles have been played by climate change and other environmental factors compared with evolving consumer preferences and expert ratings? In this paper we explore these questions using international evidence, combining time-series data on the alcohol content of wine from a large number of countries that experienced different patterns of climate change and influences of policy and demand shifts. We also examine the relationship between the actual alcohol content of wine and the alcohol content stated on the label. The systematic patterns here suggest...

Spatial Externalities and Vector-Borne Plant Diseases: Pierce’s Disease and the Blue-Green Sharpshooter in the Napa Valley 31
Fuller, Kate B.; Alston, Julian M.; Sanchirico, James N..
Pierce’s Disease (PD) is a bacterial disease that can kill grapevines over a span of one to three years. In this paper, we examine and model PD and vector control decisions made at the vineyard level in the Napa Valley in an effort to understand how the pest and disease affect individual growers, and to examine spatial externality issues and potential benefits from cooperation between adjacent vineyards. The model that we created adds to the literature by (a) treating grape vines as capital stocks that take time to reach bearing age and thus cannot be immediately replaced in the event of becoming diseased. We also (b) relax the assumption of an interior solution by examining the boundaries of parameter space for which winegrape growing is profitable and...
