We model the dynamic volatility and correlation structure of electricity futures of the European Energy Exchange index. We use a new multiplicative dynamic conditional correlation (mDCC) model to separate long-run from short-run components. We allow for smooth changes in the unconditional...

In this paper we extend the model of Easley and O’Hara (1992) to allow the arrival rates of informed and uninformed trades to be time-varying and forecastable. We specify a generalized autoregressive bivariate process for the arrival rates of informed and uninformed trades and estimate the...

Since the introduction of the autoregressive conditional heteroskedastic (ARCH) model in Engle (1982), numerous applications of this modeling strategy have already appeared. A common finding in many of these studies with high frequency financial or monetary data concerns the presence of an...

The capital asset pricing model provides a theoretical structure for the pricing of assets with uncertain returns. The premium to induce risk-averse investors to bear risk is proportional to the nondiversifiable risk, which is measured by the covariance of the asset return with the market...

In this paper, we define dynamic and static factors and distinguish between the dynamic and static structure of asset excess returns. We examine the value-weighted market portfolio as a dynamic factor and propose an intuitively appealing procedure to search for more dynamic factors. We find...

We document that the deregulation of bank branching restrictions in theUnited States triggered a reallocation across sectors, with end effectson state-level volatility. This change in state-level volatility cannotbe explained simply by shifts in sector-level returns and volatility. Areallocation...

We consider a moral hazard setup wherein leveraged firms have incentivesto take on excessive risks and are thus rationed when they attempt toroll over debt. Firms can sell assets to alleviate rationing. Liquidatedassets are purchased by non-rationed firms but their borrowing capacityis also...

We examine how the banking sector may ignite the formation of assetprice bubbles when there is access to abundant liquidity. Inside banks,given lack of observability of effort, loan officers (or risk takers)are compensated based on the volume of loans but are penalized if bankssuffer a high...

Using unsecured bonds traded in the U.S. between 1990 and 2012, we find that bond credit spreads are sensitive to risk for most financial institutions, but not for the largest financial institutions. This “too big to fail” relation between firm size and the risk sensitivity of bond spreads...

We build an equilibrium model of commodity markets in which speculators are capital constrained, and commodity producers have hedging demands for commodity futures. Increases in producers' hedging demand or speculators' capital constraints increase hedging costs via price-pressure on futures....
