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...

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...

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...

We combine existing balance sheet and stock market data with two new datasets to study whether, how much, and why bank lending to firms matters for the transmission of monetary policy. The first new dataset enables us to quantify the bank dependence of firms precisely, as the ratio of bank debt...

This paper proposes a model of financial markets and corporate finance, with asymmetric information and no taxes, where equity issues, Bank debt and Bond financing may all co-exist in equilibrium. The paper emphasizes the relationship Banking aspect of financial intermediation: firms turn to...

We analyze recent contributions to growth theory based on the model of expanding variety of Romer (1990). In the first part, we present different versions of the benchmark linear model with imperfect competition. These include the “labequipment” model, labor-for-intermediates” and...

There are two fundamental puzzles about trade credit: why does it appear to be so expensive,and why do input suppliers engage in the business of lending money? This paper addresses and answers both questions analysing the interaction between the financial and the industrial aspects of the...

In this paper I present a model in which production requires two types of labor inputs: regular productive tasks and organizational capital, which is accumulated by workers performing organizational tasks. By allocating more workers from organizational to productive tasks, firms can temporarily...
