Risk, Uncertainty and ProfitOne of the twentieth century's most influential economics texts, Risk, Uncertainty and Profit provided the theoretical basis of the entrepreneurial American economy during the post industrial era.

One of the twentieth century's most influential economics texts, Risk, Uncertainty and Profit provided the theoretical basis of the entrepreneurial American economy during the post-industrial era. This revolutionary work taught the world how to systematically distinguish between risk (randomness with knowable probabilities), and uncertainty (randomness with unknowable probabilities), in order to accurately and properly ascertain a venture's potential profitability.Author Frank H. Knight's methodology served as the foundation of the Chicago School of Economics, maintaining that competition in a free market economy is the best method for achieving economic health. In this 1921 book, Knight explains why perfect competition would not necessarily eliminate profits, because of "uncertainty," rather than "risk." He contends that even in long-run equilibrium, entrepreneurs would earn profits as a return for their toleration of uncertainty. Knight's reasoning remains valid in the twenty-first century, and his definitions of risk and uncertainty continue to be taught in modern economics classes.
Sociologist Edward Shils declared Risk, Uncertainty and Profit "a brilliant book," noting its interest not only to economists but also to social philosophers, sociologists, game theorists, and other specialists in social science.

Nice set of balls
Size: Medium
The squeaker quickly became my dog’s favorite ball and has replaced the fuzzy tennis balls. My dog is a nonstop fetcher and these chuck it balls are durable and fun.

Size: Medium
The orange and blue ball is perfect. Once start taken because the because the blue noisy one was a little to easy for my dog to start ripping pieces off. Will say most toys do not survive his chewing.

Aggressive chewer who loves fetch approved!!
Size: Medium, Size: Medium
I highly recommend the Chuck-It brand in general, especially for dogs with an aggressive bite. These balls are awesome and are the most durable balls I’ve bought for my 50 lbs lab mix. He has not been able to break one of them yet and we’ve had a few of the squeaky balls for months. They are a bit pricey but worth it.
The one in the pic has been used for months, lives outside and you can see it’s still in great shape.

Good quality dog ball for playing fetch
Size: Medium
My dog and family love these chuck it balls to play fetch with our dog. They are durable and fun. They squeak which is added fun for any dog! Regular tennis balls my dog chews apart and they get pretty gross after playing and being left outside. These can be easily washed off and cleaned. These balls last! Would recommend to anyone with a dog and would purchase again.
