Affiliates Jones-Smith, Knox, Oddo and CSDE Scientist Hurvitz co-author Study on Seattle’s Sweetened Beverage Tax

CSDE Affiliates Jessica Jones-Smith, Melissa Knox, and Vanessa Oddo, along with CSDE Research Scientist Philip Hurvitz recently published an article in Economics & Human Biology examining the impact of a sweetened beverage tax on beverage prices.

In secondary analyses, they also assess the effect of the tax on the price of non-taxed beverages and foods.
