Informed migration, uninformed migration and improved information are the three main potential effects of derivative introduction that, alone or combined, may generate significant changes on volumes, bid-ask and volatility on the underlying asset. Some combinations of these three effects are...

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...

In this paper I develop a general equilibrium model with risk averse entrepreneurial firms and with public firms. The model predicts that an increase in uncertainty reduces the propensity of entrepreneurial firms to innovate, while it does not affect the propensity of public firms to innovate....

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...

This paper proposes a structural model that analyses the way financing constraints affect investment, consumption and saving decisions of the entrepreneur of a small/medium firm. The entrepreneur may face financing constraints because he cannot precommit to repay debt, unless the debt is secured...

We develop a structural model of an industry with many entrepreneurial firms in order to investigate the cyclical behaviour of aggregate fixed investment, variable capital investment and output. In particular, we consider an environment in which the entrepreneur cannot borrow unless the debt is...

A number of studies show that entrepreneurial households face a large amount of unvidersifiable risk. This paper studies the effects of this risk on the relationship between uncertainty, innovation and investment dynamics. In the first part of the paper we develop a simple model of a risk averse...

I estimate the effect of uncertainty on risky innovation using a panel of 11,417 manufacturing firms. I find that an increase in uncertainty has a large negative effect on the risky innovation of entrepreneurial firms, while it does not have any significant impact on other firms. This negative...
