Food Taxes: How Likely Are Likely Effects?

I want to thank block and willett (1) for their comments on my paper (2). their remarks are substantial, thoughtful and they help us to discuss more profoundly one example of a food tax, the tax on sugar-sweetened beverages (ssbs). indeed, not all food taxes are created equal and next to a more general debate, we need to discuss into details every kind of attempt to tackle the increasing prevalence of obesity and diabetes. though ssbs were not in particular what i had in mind, of course they are included in the debate.
