Tariffs: An Economist's POV

Spoiler Alert:
Economists don’t like tariffs. Economists tend not to like taxes in general; they distort incentives. If you only take home 50% of your paycheck, there’s less incentive to show up at work, and more incentive to hit the beach. But tariffs are particularly disliked as their distortions, in theory, come at a higher cost.

Why AI Writing Code Will Require More People Coding

Trying to explain to college students or big corporate types that GPT doesn’t “solve” the need for engineers feels like swimming upstream. I’m sure the next 5 years will be met with broken expectations and using GenAI to create a pile of terrible systems at a scale that wasn’t humanly possible before.

One hears a lot about “Big Data.” Everyone seems to want to use it, in combination with AI, to print money and retire at 35. Big data is something System2 deals with every day. But what if someone asks you to come up with a forecast for direct-to-consumer revenue for Canada Goose? Or Allbirds? Historical revenue data can be pretty limited; typically, we’re dealing with 15 to 30 quarterly observations. How do we take big data and use it to forecast small data?

The Paradox of Models: Embracing Imperfection for Practical Insight

Models serve as powerful tools that enable analysts to extract valuable insights from complex data. Moreover, model building gives analysts a tool to uncover biases, identify patterns, and separate real growth from seasonality. However, the famous quote by statistician George Box, "All models are wrong, but some are useful," challenges us to confront the inherent paradoxes that surround the world of modeling.
