This paper shows that a transaction tax makes trades in decentralized markets more information sensitive and enlarges the range of information costs for which the equilibrium exhibits private information acquisition and endogenous adverse selection. A transaction tax reduces the probability of...

Short-term debt that can serve as a medium of exchange is designed to be information insensitive. No one should be tempted to acquire private information to gain an informational advantage in trading that could destabilize the value of the debt.

In this paper we propose an empirical measure of information sensitivity based on historical prices. If long term Treasury bonds with riskless payments are not held to maturity its information sensitivity is 0.4% higher than the S&P500 index in the period 2010 to 2020. We derive an information...
