Everybody wants to be happy. But how much happiness precisely will each life choice bring? Should I get married? Am I really going to feel happy about the career that I picked? How can we decide not only which choice is better for us, but how much its better for us? The result of new, unique research, The Happiness Equation brings to a general readership for the first time the new science of happiness economics. It describes how we can measure emotional reactions to different life experiences and present them in ways we can relate to. How, for instance, monetary values can be put on things that cant be bought or sold in the market such as marriage, friendship, even death so that we can objectively rank them in order of preference. It also explains why some things matter more to our happiness than others (like why seeing friends is worth more than a Ferrari) while others are worth almost nothing (like sunny weather). Nick Powdthavee whose work on happiness has been discussed on both the Undercover Economist and Freakanomics blogs brings cutting-edge research on how we value our happiness to a general audience, with a style that wears its learning lightly and is a joy to read.
