Risk parity is an asset allocation strategy designed so each asset class contributes equally to overall portfolio risk (as measured by volatility). While risk parity offers potential advantages, its success hinges on key assumptions and a favorable environment for bonds. Like the traditional...

There is a strand of CAPM based analytical research in accounting that uncovers a little known CAPM corollary, namely that the firm's cost of capital is a joint effect of its payoff risk and payoff mean. The CAPM equilibrium mechanism has the effect that the "numerator" (expected payoff) drives...

Stocks with high idiosyncratic volatility perform poorly relative to low idiosyncratic volatility stocks. We offer a novel explanation of this anomaly based on real options, which is consistent with earlier findings on idiosyncratic volatility (the positive contemporaneous relation between...

While discussing risk issues someone told me as a joke that she wished the world were riskless and the fact that risk were present in any instance in our lives was a rather unfortunate circumstance. But would we be really better off in a riskless world?Although it may appear to be a trivial...

If two investments have the same payoff covariance with the market but one has higher expected payoff, which asset according to the CAPM has most risk? One answer is that as far as risk goes the two assets are the same, because they have the same covariance with the market. The correct answer,...

We propose and test a theory of corporate liquidity management in which credit lines provided by banks to firms are a form of monitored liquidity insurance. Bank monitoring and resulting credit line revocations help control illiquidity-seeking behavior by firms. Firms with high liquidity risk...

We address the paradox that financial innovations aimed at risk-sharing appear to have made the world riskier. Financial innovations facilitate hedging idiosyncratic risks among agents; however, aggregate risks can be hedged only with liquid assets. When risk-sharing is primitive, agents...

Does risk shifting incentives or risk management incentives dominate when firms rollover large amounts of maturing debt? The empirical evidence supports the risk management hypothesis by identifying a hump-shaped relation between long-term debt maturity and firm risk. Using...

The interaction of capital and risk for trading and treasury units is of primary interest in the corporate governance of banks as it links operational profitability and strategic risk management. During the financial crisis, several banks' trading units suffered significantly higher losses than...
