Token-Based Platform Finance
AbstractWe develop a dynamic model of platform economy where tokens derive value by facilitating transactions among users and the platform conducts optimal token-supply policy to finance investment in platform quality and to compensate platform owners. Even though token price is endogenously determined in a liquid market, the platform's financial constraint generates an endogenous token issuance cost that causes under investment and conflict of interest between insiders (owners) and outsiders (users). The franchise value (seigniorage) incentivizes the owners to buy back and burn tokens out of circulation, reducing token price volatility. Blockchain technology is crucial for token-based platforms because it enables platform owners to commit to predetermined rules of token supply that can significantly improve efficiency by addressing platform owners' time inconsistency and mitigating under-investment.
Equilibrium Bitcoin Pricing
AbstractWe offer an overlapping generations equilibrium model of cryptocurrency pricing and confront it to new data on bitcoin transactional benefits and costs. The model emphasizes that the fundamental value of the cryptocurrency is the stream of net transactional benefits it will provide, which depend on its future prices. The link between future and present prices implies that returns can exhibit large volatility unrelated to fundamentals. We construct an index measuring the ease with which bitcoins can be used to purchase goods and services, and we also measure costs incurred by bitcoin owners. Consistent with the model, estimated transactional net benefits explain a statistically significant fraction of bitcoin returns.
