This paper studies the macroeconomic implications of firmsprecautionary investment behavior in response to the anticipation of future financing constraints. Firms increase their demand for liquid and safe investments in order to alleviate future borrowing constraints and decrease the probability...

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 explore a view of the crisis as a shock to investor sentiment that led to the collapse of a bubble or pyramid scheme in financial markets. We embed this view in a standard model of the financial accelerator and explore its empirical and policy implications. In particular, we show how the...

We study a dynamic economy where credit is limited by insufficient collateral and, as a result, investment and output are too low. In this environment, changes in investor sentiment or market expectations can give rise to credit bubbles, that is, expansions in credit that are backed not by...

This paper proposes an alternative explanation to recurrent hyperinflations other than bounded rationality by explicitly considering the global dynamics of an economy with credit market frictions. In this paper we show that hyperinflations are self-generated and are manifestations of the...

We develop a stylized model of economic growth with bubbles. In this model, financial frictions lead to equilibriumdispersion in the rates of return to investment. During bubbly episodes, unproductive investors demand bubbles while productive investors supply them. Because of this, bubbly...

Balance sheet recessions result from concentration of macroeconomic risks on the balance sheets of leveraged agents. In this paper, I argue that information dispersion about the future states of the economy combined with trading frictions in financial markets can explain why such concentration...

The financial crisis of 2007-08 has underscored the importance of adverse selection in financial markets. This friction has been mostly neglected by macroeconomic models of financial frictions, however, which have focused almost exclusively on the effects of limited pledgeability. In this paper,...

This paper presents evidence that the existence of deposit and lending facilities combined with an averaging provision for the reserve requirement are powerful tools to stabilize the overnight rate. We reach this conclusion by comparing the behavior of this rate in Germany before and after the...
