Information pertaining to new addresses is highly value-relevant in the cryptocurrency market. Innovations to the number of new addresses explain eight percent of the variations in cryptocurrency returns. Unlike traditional markets, we do not find evidence of pre- or post-drift around the...

We demonstrate how a static optimal income taxation problem can be analyzed using dynamical methods. We show that the taxation problem is intimately connected to the heat equation and derive a new property of the optimal tax which we call the fairness principle. The optimal tax at a given income...

We find that three factors - cryptocurrency market, size, and momentum - capture the cross-sectional expected cryptocurrency returns. We consider a comprehensive list of price- and market-related factors in the stock market, and construct their cryptocurrency counterparts. Nine cryptocurrency...

We consider a small set of axioms for income averaging - recursivity, continuity, and the boundary condition for the present. These properties yield a unique averaging function that is the density of the reflected Brownian motion with a drift started at the current income and moving over the...

We associate a dynamical system with input-output networks and study its spectral properties. Specifically, we develop a dynamic production network model featuring adjustment costs of changing inputs and thus gradual recovery from temporary TFP shocks. First, we explicitly solve for the output...

We study the optimal Mirrlees taxation problem in a dynamic economy with idiosyncratic (productivity or preference) shocks. In contrast to the standard approach, which implicitly assumes that the mechanism is operated by a benevolent planner with full commitment power, we assume that any...

We develop a stylized currency crises model with heterogeneous information among investors and endogenous determination of interest rates in a noisy rational expectations equilibrium. Our model captures three key features of interest rates: the opportunity cost of attacking the currency responds...
