In a simple search model of money, we study a special kind of memory that gives rise to an arrangement resembling a payment network. Specifically, we assume that agents can pay a cost to access a central database that tracks payments made and received. Incentives must be provided to agents to...

We examine incentives for network-specific investment and consider the implications for network governance. We model a two-sided market in which participants making payments over a network platform can invest in a technology that reduces the marginal cost of using the platform. A network effect...

This paper considers money creation by banks and central banking in a model where a means of payment is issued by both the central bank and banks, and the private issuance is endogenous in competitive equilibrium. The economy lasts for two dates, but the central bank gets its purely nominal...

In a simple search model of money, we study a special kind of memory which gives rise to an arrangement resembling a payment network. Specifically, we assume that agents can choose to have access to a central data base which keeps track of payments made and received. We show that multiple...

We examine incentives for network-specific investment and the implications for network governance. We model an environment in which participants that make payments over a network can invest in a technology that reduces the marginal cost of using the network. A network effect results in multiple...

This paper offers a model of crowdfunding that represents a growing area of interest among practitioners and theorists. It is one of the first articles analyzing the choice between different types of crowdfunding (reward-based vs. equity-based) and the choice between crowdfunding and traditional...

Automotive manufacturers are known to use deadline-based convex incentives to motivate dealerships to sell new cars. This paper shows that dealerships respond to these incentive targets by pushing customers from used to new cars as the end of the month approaches, and that subprime loans written...

Web3 and DeFi are widely advocated as innovations for greater financial inclusion and democratization. We assemble the most comprehensive dataset to date on the largest Web3 ecosystem and use large-scale computing to conduct an initial investigation. We describe Ethereum's network structure,...
