Abstract
People are obviously getting more and more fat. This fact cannot be denied. That is why, to curb this phenomenon, Kelly Brownell launched the idea of applying a fat tax on unhealthy food, in his article published in the New York Times in 1994. Such a tax could encourage people to buy less unhealthy food. From then on, the point is to analyze the tax features and its effects on general consumption. First, I will focus on the way of applying a new tax on fat products, studying the two goods market, vegetables and ice-cream, presented here. Then I will try to explain what effects the tax could generate on the consumption of these two goods. By doing so, it will help me to show that a fat tax could be a good way to prevent people from buying unhealthy food.
