Market share instability, during certain stages of the industry life-cycle, has become a stylized fact in the industrial organization literature. In the finance literature, volatility in the form of excess volatility, i.e. the much larger volatility of stock prices than dividends (although stock...

Recent studies find that idiosyncratic risk (IR) the degree to which firm-specific returns are more volatile than aggregate market returns has increased since the 1960s and attribute this to economy-wide factors such as the role of the IT revolution. Yet no innovation data is used in these...

This paper focuses on a single simple stylized fact which stands out from the post-war history of the US Car industry, namely that industry concentration fell just at the same time as industry advertising expenditures rose sharply. Since both events were almost certainly caused by the entry and...

Market share instability, during certain stages of the industry life-cycle, has become a stylized fact in the industrial organization literature.

In this paper we reconsider extensions and modifications of earlier work on a disequilibrium model of AS-AD growth. Our dynamic model exhibits more or less sluggishly adjusting prices and quantities, Keynesian demand rationing and fluctuating capacity utilization for both labor and capital....

In this paper we reconsider a model of Blanchard and Fisher which reformulated Keynesian IS-LM analysis from the perspective of a richer array of financial assets, namely short-term and long-term bonds, and thus from the perspective of the term structure of interest rates. The basic change in...

We reformulate and extend the Blanchard model of output dynamics, the stock market and interest rates that studies Keynesian IS-LM analysis from the perspective of a richer array of short-term bonds. Thus investment demand now depends on Tobin's average q in the place of the real rate of...

The pricing and control of firms` debt has become a major issue since Merton`s (1974) seminal article. Yet Merton as well as other recent theories presume that the asset value of the firm is independent of the debt of the firm. However, when using debt finance, firms may have to pay a premium...

This paper estimates the parameters of a stochastic growth model with asset market and contrasts the model's moments with moments of the actual data. We solve the model through log-linearization along the line of Campbell (1994) [Journal of Monetary Economics 33(3), 463] and estimate the model...
