This book was written entirely by one person with just a tiny bit of assistance.
There are costs to this approach, which I will get to shortly, but one big advantage:
is possible to offer a new, coherent vision of the subject matter, free from any
pressure to conform to how things have been done in the past. In economics, I think
this one plus outweighs all the minuses, but you can judge for yourself.
Of course, no book of this type is truly the product of just one individual. Just to
be in a position to write it, I had to make my way to professional status as an
economist, and that I owe above all to my dissertation chair, Herb Gintis. To say
that Herb was an ideal advisor would be an understatement; he really took me under
his wing and did whatever it took (including occasional childcare) to help me
succeed. My debt to him cannot ever be repaid.
