We formalize the link between optimal cost-sharing contracts and the production technology in the presence of moral hazard by appealing to several well-known results from duality theory. Building on intuitions from the interlinkage literature, we show that optimal contractual structure is...

of the resolution of uncertainty combined with endowments containing a slowly moving trend can result in extremely high welfare gains. The model is also able to account for a large set of international finance stylized facts. Our setup allows us to bridge part of the gap between the current...

We develop a dynamic model of platform economy where tokens derive value by facilitating transactions among users and the platform conducts optimal token-supply policy. Token supply increases when new tokens are issued to finance platform growth and to reward platform owners. Token supply...

We develop a dynamic asset-pricing model of cryptocurrencies/tokens that allow users to conduct peer-to-peer transactions on digital platforms. The equilibrium value of tokens is determined by aggregating heterogeneous users' transactional demand rather than discounting cashflows as in standard...

Deposits finance bank lending and serve as means of payment for bank customers. Under uncertain payment flows, deposits are debts with random maturities. Payment outflows drain reserves, and the risk is most prominent when funding markets are under stress and banks are unable to smooth out...

This paper documents a strong connection between payment system and credit supply. The dual role of deposits as financing instruments for banks and means of payment for bank customers implies spillover effects of bank lending. After a bank finances loans with new deposits, the deposit holders'...

Stablecoins rise to meet the demand for safe assets in decentralized finance. Stablecoin issuers transform risky reserve assets into tokens of stable values, deploying a variety of tactics. To address the questions on the viability of stablecoins, regulations, and the initiatives led by large...

We propose a dynamic theory of banking where the role of deposits is akin to that of productive capital in the classical Q-theory of investment for non-financial firms. As a key source of leverage, deposits create value for well-capitalized banks. However, unlike productive capital of...

We propose a dynamic theory of banking where deposits play the role of productive capital as in the classical Q-theory of investment for non-financial firms. A key conceptual innovation of our theory is that the stock of deposits cannot be perfectly controlled by the bank. Demand deposit...
