This paper introduces a new financial vulnerability index for emerging market economies by exploiting key differences in their business cycles relative to those of advanced economies. Information on the domestic price of risk, cost of dollar hedging and market-based measures of bank...

This paper examines the relationship between innovation and firms' dependence on external capital by analyzing the innovation activities of privately-held and publicly-traded firms. We find that public firms in external finance dependent industries generate patents of higher quantity, quality,...

We use portfolio theory to quantify the efficiency of state-level sectoral patterns of production in the United States. On the basis of observed growth in sectoral value-added output, we calculate for each state the efficient frontier for investments in the real economy. We study how rapidly...

We use portfolio theory to quantify the efficiency of state-level sectoral patterns of production in the United States. On the basis of observed growth in sectoral value added output, we calculate for each state the efficient frontier for investments in the real economy, the efficient Sharpe...

We document that the deregulation of bank branching restrictions in the United States triggered a reallocation across sectors, with end effects on state-level volatility. This change in state-level volatility cannot be explained simply by shifts in sector-level returns and volatility. A...

We document that the deregulation of bank branching restrictions in the United States triggered a reallocation across sectors, with end effects on state-level volatility. The change cannot be explained simply by shifts in sector-level returns and volatility. A reallocation effect is at play,...

We study an economy subject to recurrent disasters when agents have imprecise information about the frequency and duration of the disasters. Uncertainty about the persistence of states can lead to seemingly pessimistic behavior in bad times and optimistic behavior in good times. In a disaster,...

One measure of the ex ante cost of disasters is the welfare gain from shortening their expected duration. We introduce a stochastic clock into a standard disaster model that summarizes information about progress (positive or negative) towards disaster resolution. We show that the stock market...

We examine how the banking sector could ignite the formation of asset price bubbles when there is access to abundant liquidity. Inside banks, to induce effort, loan officers are compensated based on the volume of loans. Volume-based compensation also induces greater risk taking; however, due to...
