It has been a while since my last post. What does a golf cart, AI and growth have in common? I will begin talking about Golf carts. In Florida, as well as in regions where people enjoy playing golf, golf carts are very high on demand. One can buy a golf cart nearly at the ….  Read More

It is commonly accepted as a premise that the body is wise: it knows when it needs something. For example, one might be craving an apple or even chocolate.

His main thesis is that there have been three industrial revolutions and that nothing beats the second one: the invention of cars, airplanes, steel industry, chemical industry, strong ….  Read More

Today I want to talk a little bit about a family of prefernces which are famous in macro economics, the GHH preferences. Their origins go back to 1988 to a paper by Jeremy Greenwood, Zvi Hercowitz, and Gregory Huffman. The main idea of the function is to achieve some sort of separability of the labor ….  Read More
