Originators produce higher quality assets at a private cost. These assets can either be bought by informed intermediaries or sold in a pool with low quality assets. Savings gluts diminish origination incentives because they compress the spread between the price paid for high quality assets and...

We consider a model of liquidity demand arising from a possible maturity mismatch between asset revenues and consumption. This liquidity demand can be met with either cash reserves (inside liquidity) or via asset sales for cash (outside liquidity). The question we address is, what determines the...

China s stock markets, with stringent short-sales constraints, dominance of inexperienced individual investors, a small asset float and heavy share turnover (500% per year despite a high transaction cost), provide a unique opportunity to study non-fundamental components in stock prices. In...

We create an analytical structure that reveals the long run risk-return relationship for nonlinear continuous time Markov environments. We do so by studying an eigenvalue problem associated with a positive eigenfunction for a conveniently chosen family of valuation operators. This family forms a...

We argue that the root cause behind the recent corporate scandals associated with CEO pay is the technology bubble of the latter half of the 1990s. Far from rejecting the optimal incentive contracting theory of executive compensation, the recent evidence on executive pay can be reconciled with...

We model the relationship between asset float (tradeable shares) and speculative bubbles. Investors with heterogeneous beliefs and short-sales constraints trade a stock with limited float because of insider lockups. A bubble arises as price overweighs optimists' beliefs and investors anticipate...

We model the relationship between asset float (tradeable shares) and speculative bubbles. Investors trade a stock with limited float because of insider lock-ups. They have heterogeneous beliefs due to overconfidence and face short-sales constraints. A bubble arises as price overweighs optimists'...

The market dynamics of technology stocks in the late nineties has stimulated a growing body of theories that analyze the joint effects of short-sales constraints and heterogeneous beliefs on stock prices and trading volume. This paper examines implications of these theories using a unique data...

Motivated by the behavior of asset prices, trading volume and price volatility during episodes of asset-price bubbles, we present a continuous time equilibrium model where overconfidence generates disagreements among agents regarding asset fundamentals. With short-sale constraints, an asset...

We present a multiperiod agency model of stock based executive compensation in a speculative stock market, where investors are overconfident and stock prices may deviate from underlying fundamentals and include a speculative option component. This component arises from the option to sell the...
