Periods of economic boom with rapid credit and GDP growth can be followed by sudden busts. In the presence of financial markets imperfections, a simple modification of a neoclassical growth model can fully account for this behavior. I study a growth model for a small open economy where...

Financial innovation has increased opportunities for diversification and lowered investment costs, but has not reduced the relative cost of active (informed) investment strategies compared with passive (less informed) strategies. What are the consequences? I have studied an economy with linear...

The rotational correlation function of anisotropic colloidal particles can be measured by observing the fluctuations of the depolarized intensity scattered in the forward direction. In this work we present a theoretical treatment of forward depolarized light scattering. Our calculations show the...

lowered investment costs, but has not reduced the relative cost of active (informed) investment strategies relative to passive (less informed) strategies. What are the consequences? I study an economy with linear production technologies, some more risky than others. Investors can use low quality...

I construct an endogenous growth model where R&D is carried out at the industry level in a game of innovation between leaders and followers. Innovation costs for followers are assumed to increase with the technological lag from leaders. We obtain three results that contrast with standard...

In emerging economies periods of rapid growth and large capital inflows can be followed by sudden stops and financial crises. I show that, in the presence of financial markets imperfections, a simple modification of a neoclassical growth model can account for these facts. I study a growth model...
