Why economic theory—with no track-record of predictive success—is still an indispensable tool for protecting civilized life.

Economic theory has never gotten any better at prediction. Its explanations are always after the fact. The mathematical models economists have devoted themselves to for more than a century can’t be improved to enhance their empirical relevance. But from this research program that never paid off, a very useful tool has emerged—game theory. It’s just what civilized society needs to protect itself from the rapaciousness that condemns all markets to fail. In Blunt Instrument, Alex Rosenberg helps explain to outsiders exactly what they need to make sense of economic theory, and why despite its failures, it’s still indispensable.

Economic theory is something we all should understand because the economy affects us all, and it is economic theorists who shape that economy for good or ill. No less an economist than John Maynard Keynes expressed the point in a memorable quotation: “Practical men, who believe themselves to be quite exempt from any intellectual influence, are usually the slaves of some defunct economist.” This book draws back the curtain from the math and the graphs that deliver microeconomic and macroeconomic models. It demystifies the formidable-looking equations, explaining the reasoning behind the math so that outsiders can decide on the theory’s importance to their own thinking about the economy. Finally, it shows how game theory—the study of strategic choice—emerged from the outlandish idealizations of economic theory. Most importantly, it illuminates how game theory both mitigates the failures of real-world economies and improves the design of important human institutions.

Our dog loves it but it wasn’t durable enough to last
Color: Dogwood Jack, Size: Large, Color: Dogwood Jack, Size: Large
Our lab took to it as soon as we gave it to her. Perfect size for our 80 lb yellow lab. However, now that it’s in about 10 days, she’s able to break off chunks from this bone that are dime size or larger, and we have to throw it away

No problems after a year and a half
Color: Dogwood & Calming, Size: Medium
Have been regularly buying these for my corgi for about a year and a half. The 2 pack lasts about a month or 2 each time. Pieces break off in small enough pieces that they safely pass through his digestive system. He gnaws each one down to about 1/4 the original size before we take it away and give him a new one. He continues to have regular bowel movements and has a healthy appetite so I can’t imagine any problems arising after so long. I have tried other alternatives and every other similar chew breaks off in larger pieces and didn’t feel comfortable letting him chew/eat them. I noticed there are a few 1 star reviews saying their dogs got sick off these but after a year and a half I have had 0 issues with this product. I guess it depends on the dog and how big of pieces they are swallowing. My dog ingests pieces about the size of a grain of rice so just pay attention and you should be fine.

Long lasting and safer alternative to sticks
Color: Dogwood & Calming, Size: Medium
These are great, very durable, and have lasted a very long time. Much safer for my dogs than the random sticks they find in the yard. They do get shorter with chewing eventually, but they don't break off in little chunks like I've seen with some nylon chews, and they don't splinter like wood. Medium size works well for both my 16 lb Cavalier and my 60 lb Pyrenees/Golden mix. They're both moderate-to-aggressive chewers, though size obviously affects how much damage they can do. I wish you could buy the hemp chew separately because that one is very much a favorite in my house, so after 2 years and 2 purchases, I have barely any left of the remaining hemp chew, but still 2 of the dogwood chews that neither dog is as interested in anymore. I'd love to buy a couple more of just the hemp one.

Your dog will thank you.
Color: Dogwood & Fresh Breath, Size: Large
My dogs loves to chew on these. They make a small mess but not as bad as other chews. They are food for keeping teeth clean.

Nice chew toy
Color: Dogwood Mushroom, Size: Medium, Color: Dogwood Mushroom, Size: Medium
Super durable and puppy loves it. It was a bit hard for her at first but now at 5 months it’s one of her favorite things to gnaw on! It is heavy for the size but seems to be great quality and has given many hours of chew time with minimal wear.
