Most stock exchange regulators around the world reacted to the 2007-2009 crisis by imposing bans or regulatory constraints on short-selling. Short-selling restrictions were imposed and lifted at different dates in different countries, often applied to different sets of stocks and featured...

We develop a model of financially constrained arbitrage, and use it to study the dynamics of arbitrage capital, liquidity, and asset prices. Arbitrageurs exploit price discrepancies between assets traded in segmented markets, and in doing so provide liquidity to investors. A collateral...

We construct a general equilibrium model in which income inequality results in insufficient aggregate demand, deflation pressure, and excessive credit growth by allocating income to agents featuring low marginal propensity to consume, and if excessive, can lead to an endogenous financial crisis....

The global financial crisis has brought to the forefront the need for executives to better understand the uses and limitations of the structural models frequently employed in the valuation and risk management activities of their firms. The mandate to better manage systemic risk exposure,...

This paper uses two highly liquid S&P 500 and gold exchange-traded funds (ETFs) to evaluate the impact of liquidity and macroeconomic news surprises on the frequency of observing intraday jumps. It explicitly addresses market microstructure noise-induced biases in realized estimators used in...

We examine price discovery and liquidity provision in the secondary market for bitcoin-an asset with a high level of speculative trading. Based on BTC-e's full limit order book over the 2013-2014 period, we find that order informativeness increases with order aggressiveness within the first 10...

Banking/financial crises have occurred in countries at all levels of income and in all parts of the world. These crises not only occur too frequently, but also are too costly. Countries everywhere therefore have enacted laws that established regulatory authorities with responsibility to...
