Housing transactions by owner-occupiers take two steps, purchase of a new property and sale of the old housing unit. This paper shows how the transaction sequence decision of owner-occupiers depends on, and in turn, affects housing market conditions in an equilibrium search-and-matching model of...

Housing transactions by existing homeowners take two steps, a purchase of a new property and sale of the old housing unit. These two decisions are not independent, and their sequence may depend on the state of the housing market. This paper shows how the sequence of buyer-seller decisions...

While the traditional view of financial innovation emphasizes the risk sharing role of new financial assets, belief disagreements about these assets naturally lead to speculation, which represents a powerful economic force in the opposite direction. This paper investigates the effect of...

Belief disagreements have been suggested as a major contributing factor to the recent financial crisis. This paper theoretically evaluates this hypothesis. I assume that optimists have limited wealth and take on leverage in order to take positions in line with their beliefs. To have a...

We investigate the role of macroprudential policies in mitigating liquidity traps driven by deleveraging, using a simple Keynesian model. When constrained agents engage in deleveraging, the interest rate needs to fall to induce unconstrained agents to pick up the decline in aggregate demand....

I illustrate the effect of financial innovation on portfolio risks by using an example with risk-sharing needs and belief disagreements. I consider two types of innovation: product innovation, formalized as an expansion of new financial assets; and process innovation, formalized as a reduction...
