**Random Quote:** *The goal of the scientist is to comprehend the
phenomena of the universe that he observes around him. To prove that he
understands he must be able to predict. To predict quantitatively one
must have a mechanism for producing numbers, and this necessarily
entails a mathematical model.* – Richard Bellman

# Economics

This page is a brief discussion of my research interests, which are centered
around macroeconomics but stray into various areas of mathematics, statistics
and computing.

## Research Interests

- Stochastic dynamics (Markov processes)
- Distribution dynamics (evolution and properties of firm, income and wealth distributions)
- Dynamic programming
- Computational and numerical methods (simulation, algorithms, etc.)
- Asset pricing
- Time series analysis
- Assorted outliers, including economic development, optimal transport and the theory of the firm
