We clarify the conventional claims concerning the most popular damage measures: expectation damages (ED), constant damages (CD), and reliance damages (RD). We strictly examine strategies versus outcomes in equilibrium and make several new investigations. In terms of equilibrium outcomes, we...

The directed search model (Peters, 1984) is static; its dynamic extensions typically restrict strategies, often assuming price or match commitments. We lift such restrictions to study equilibrium when search can be directed over time, without constraints and at no cost. In equilibrium trade...

This paper shows that an incumbent monopolist's incentive confronting a new entrant depends on the degree of product differentiation and the strength of network externality. If products are homogeneous, the incumbent never wants to invite entry regardless of the degree of network externality. On...

The lack of complete information has been considered as a barrier to the optimal regulation. This paper shows that this is true for price regulation, but not for entry regulation. The performance of an entry regulation under asymmetric information can be better than that under complete...

In the United Kingdom, money demand deviates from the convex relationship suggested by monetary theory. Limited commitment of borrowers via banks can explain this observation. Our finding is based on a microfounded monetary model, where a money market provides insurance against idiosyncratic...

In the 1990s, the empirical relation between money demand and interest rates began to fall apart. We analyze to what extent improved access to money markets can explain this break-down. For this purpose, we construct a microfounded monetary model with a money market, which provides insurance...

We investigate the positive and normative implications of a tax on financial market transactions in a dynamic general equilibrium model, where agents face idiosyncratic liquidity shocks and financial trading is essential. Our main finding is that agents' portfolio choices display a pecuniary...

Do financial market participants free-ride on liquidity? To address this question, we construct a dynamic general equilibrium model where agents face idiosyncratic preference and technology shocks. A secondary financial market allows agents to adjust their portfolio of liquid and illiquid assets...

Can there be too much trading in financial markets? To address this question, we construct a dynamic general equilibrium model, where agents face idiosyncratic preference and technology shocks. A financial market allows agents to adjust their portfolio of liquid and illiquid assets in response...
