If you are looking to read a book by Richard Posner, don’t start with this one. This book is just a series of scantily connected essays threaded together by a little to a lot of economic reasoning in each depending on which essay it is. By themselves, each essay is fascinating—you’ll certainly learn something surprising with each one. But I struggle to understand why they were all collected in a book like this.
Judging simply by the title of the book “The Economics of Justice” and by Posner’s reputation as the neigh genius 7th Circuit Judge/UChicago Professor who stood astride the law & economics movement like a bespectacled economic Colossus of Rhodes, I was under the impression this book would, well, use economics to explain how the pursuit of justice was guided by invisible market forces to reach efficient laws at equilibrium, whose price, borne by the consumer (those who the law restricts) was brought down to the law’s marginal cost on society (derived by a balancing of the costs and benefits of having the law). Or something like that type of analysis.
Indeed, this is what you get with a few of the essays: the one justifying wealth maximization as the target to resolve conflicts where the transaction costs were too high such that it would be infeasible to aim at simply lubricating mutually beneficial exchange through private transactions as the law’s purpose is in contract law, where the parties can easily bargain with each other. In tort law, for example, where the transaction costs are too high for parties to transact with each other before the accident, the judge should use the hypothetical market, which will yield the rule that ends up maximizing wealth—thus the common law is efficient. Or there are also the essays detailing the efficiency of customs in ancient societies, customs we see today as absurd, such as excessive gift giving, witch hunting, superstition, vengeance and retaliation, etc, back then were efficient reactions to the contingencies of the time—high information costs, little to no privacy, a night watchman state (or even less). These were brilliant essays fitting the topic. Then there are others. Fascinating but perhaps better suited to a legal history book, such as his essay fleshing out the drama between Bentham and Blackstone. And at the end, he gives a rundown of current privacy and discrimination laws and how they are inefficient or could be made more efficient. Interesting, mildly economic, but not what I wanted out of this book.
TLDR: some of the essays were worth six stars, others, worth one simply because they aren’t what I expected when I bought the book.
