We model the firm's optimal choice of capital and goodness subject to financial constraints. Managers and shareholders derive benefits over profits and social responsibility. Goodness is costly and its marginal benefit is finite; as a result, less-constrained firms spend more on goodness. We...

We propose an equilibrium occupational choice model, where agents can choose to work in the real sector (become entrepreneurs) or to become informed dealers in financial markets. Agents incur costs to become informed dealers and develop skills for valuing assets up for trade. The financial...

As the record of Fed interventions from December 2007 to December 2008 make abundantly clear, a foremost concern of monetary authorities in responding to the financial crisis has been to avoid a repeat of the great depression, and especially a repeat of the monetary contraction identified as the...

An influential thesis, dubbed "Doing Well by Doing Good", argues that corporate social responsibility is profitable. We establish that, if anything, the reverse is true: firms do good only when they do well in the sense of having financial slack. We model a firm's optimal choices of capital and...

An influential thesis, dubbed "Doing well by doing good," argues that corporate social responsibility is profitable. But heterogeneity in firm financial constraints can induce a spurious correlation between profits and goodness even if the motives for goodness are non-profit in nature. We use...

We propose a model where investors can choose to acquire costly information that allows them to identify good assets and purchase them in opaque over the counter (OTC) markets. Uninformed investors trade on an organized exchange and only have access to an asset pool that has been (partially)...

Many believe that compensation, misaligned from shareholders' value due to managerial entrenchment, caused financial firms to take creative risks before the Financial Crisis of 2008. We argue instead that even in a classical principal-agent setting without entrenchment and with exogenous...

In this paper, we consider an evolution non local free boundary problem that arises in the modeling of speculative bubbles. The solution of the model is the speculative component in the price of an asset. In the framework of viscosity solutions, we show the existence and uniqueness of the...

We test implications of a simple equilibrium model of informality using a survey of 48,000 small firms in Brazil. In the model, agent's ability to manage production differ and informal firms face a higher cost of capital and limitation on size, although these informal firms avoid tax payments....
