Income Tax Evasion Dynamics

I have no idea what this paper is about — the jargon is particularly opaque — but any paper that works in income tax evasion and ferromagnetism is, by definition, worth noting.

Income Tax Evasion Dynamics: Evidence from an Agent-based Econophysics Model

We analyze income tax evasion dynamics in a standard model of statistical mechanics, the Ising model of ferromagnetism. However, in contrast to previous research, we use an inhomogeneous multi-dimensional Ising model where the local degrees of freedom (agents) are subject to a specific social temperature and coupled to external fields which govern their social behavior. This new modeling frame allows for analyzing large societies of four different and interacting agent types. As a second novelty, our model may reproduce results from agent-based models that incorporate standard Allingham and Sandmo tax evasion features as well as results from existing two-dimensional Ising based tax evasion models. We then use our model for analyzing income tax evasion dynamics under different enforcement scenarios and point to some policy implications.

Me Being Animated: Money and Markets

So, this was fun: I talked about funding young companies, and about sources of risk capital, and it got turned into an animation. It’s not Bugs Bunny, but it’s as close as I’ll get.

England as Rogue State

“England, a nation of about 5 million people in 1650, was in many ways becoming the most disruptive power in the Atlantic world — a rogue state.”

Apple/Google/Amazon P/E Over Time

Was looking at this historical graph of technology price/earnings ratios over time for a talk I’m putting together, so I thought I’d share. Interesting to see Apple and Google moving valuations more or less together, and Amazon off in the stratosphere.
