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.
