This paper studies the macroeconomic implications of firms' investment composition choices in the presence of credit constraints. Following a negative and persistent aggregate productivity shock, firms shift into short-term investments because they produce more pledgeable output and because they...

In this paper we offer the first large sample evidence on the availability and usage of credit lines in U.S. public corporations and use it to re-examine the existing findings on corporate liquidity. We show that the availability of credit lines is widespread and that average undrawn credit is...

This paper shows that liquidity constraints restrict job creation even when labor markets are flexible. In a dynamic model of labor demand, I show that in an environment of imperfect capital and imperfect labor markets, firms use temporary contracts to relax financial constraints. Evidence for...

We develop a model of an industry with many heterogeneous firms that face both financing constraints and irreversibility constraints. The financing constraint implies that firms cannot borrow unless the debt is secured by collateral; the irreversibility constraint that they can only sell their...

We set up a dynamic model of firm investment in which liquidity constraints enter explicity into the firm's maximization problem. The optimal policy rules are incorporated into a maximum likelihood procedure which estimates the structural parameters of the model. Investment is positively related...

This paper presents a new framework for studying irreversible (dis)investment when a market follows a random number of random-length cycles (such as a high-tech product market). It is assumed that a firm facing such market evolution is always unsure about whether the current cycle is the last...

We consider a dynamic multifactor model of investment with financing imperfections, adjustment costs and fixed and variable capital. We use the model to derive a test of financing constraints based on a reduced form variable capital equation. Simulation results show that this test correctly...
