This paper examines security design in imperfectly competitive markets in which assets clear separately rather than jointly. Derivatives are generally nonredundant even with zero asset supply. We characterize the scope for introducing nonredundant derivatives and examine the welfare effects of...

Advances in market-clearing technology for multiple assets and synthetic products present alternative ways to leverage complementarities and substitutabilites in asset payoffs. This paper compares their equilibrium and welfare effects. Our results underscore the difference the price impact makes...

We develop a general model of decentralized exchange. Our model allows for any number of traders and traded assets, and any form of market decentralization, including trading environments determined by an arbitrary network structure. We study how the equilibrium allocation and liquidity depend...

Most assets are traded in multiple interconnected trading venues. This paper develops an equilibrium model of decentralized markets that accommodates general market structures with coexisting exchanges. Decentralized markets can allocate risk among traders with different risk preferences more...
