"Derivative contracts, swaps, and repos enjoy "super-senior" status in bankruptcy: they are exempt from the automatic stay on debt and collateral collection that applies to virtually all other claims. We propose a simple corporate finance model to assess the effect of this exemption on firms' cost of borrowing and incentives to engage in swaps and derivatives transactions. Our model shows that while derivatives are value-enhancing risk management tools, super-seniority for derivatives can lead to inefficiencies: collateralization and effective seniority of derivatives shifts credit risk to the firm's creditors, even though this risk could be borne more efficiently by derivative counterparties. In addition, because super-senior derivatives dilute existing creditors, they may lead firms to take on derivative positions that are too large from a social perspective. Hence, derivatives markets may grow inefficiently large in equilibrium"--National Bureau of Economic Research web site

"We propose an equilibrium occupational choice model, where agents can choose to work in the real sector (become entrepreneurs) or to become informed dealers in financial markets. Agents incur costs to become informed dealers and develop skills for valuing assets up for trade. The financial sector comprises a transparent competitive exchange, where uninformed agents trade and an opaque over-the-counter (OTC) market, where informed dealers offer attractive terms for the most valuable assets entrepreneurs put up for sale. Thanks to their information advantage and valuation skills, dealers are able to provide incentives to entrepreneurs to originate good assets. However, the opaqueness of the OTC market allows dealers to extract informational rents from entrepreneurs. Trade in the OTC market imposes a negative externality on the organized exchange, where only the less valuable assets end up for trade. We show that in equilibrium the dealers' informational rents in the OTC market are too large and attract too much talent to the financial industry"--National Bureau of Economic Research web site

"We analyze contagious sovereign debt crises in financially integrated economies. Under financial integration banks optimally diversify their holdings of sovereign debt in an effort to minimize the costs with respect to an individual country's sovereign debt default. While diversification generates risk diversification benefits ex ante, it also generates contagion ex post. We show that financial integration without fiscal integration results in an inefficient equilibrium supply of government debt. The safest governments inefficiently restrict the amount of high quality debt that could be used as collateral in the financial system and the riskiest governments issue too much debt, as they do not take account of the costs of contagion. Those inefficiencies can be removed by various forms of fiscal integration, but fiscal integration typically reduce the welfare of the country that provides the "safe-haven" asset below the autarky level"--National Bureau of Economic Research web site

"We study a dynamic-contracting problem involving risk sharing between two parties - the Proposer and the Responder - who invest in a risky asset until an exogenous but random termination time. In any time period they must invest all their wealth in the risky asset, but they can share the underlying investment and termination risk. When the project ends they consume their final accumulated wealth. The Proposer and the Responder have constant relative risk aversion R and r respectively, with R>r>0. We show that the optimal contract has three components: a non-contingent flow payment, a share in investment risk and a termination payment. We derive approximations for the optimal share in investment risk and the optimal termination payment, and we use numerical simulations to show that these approximations offer a close fit to the exact rules. The approximations take the form of a myopic benchmark plus a dynamic correction. In the case of the approximation for the optimal share in investment risk, the myopic benchmark is simply the classical formula for optimal risk sharing. This benchmark is endogenous because it depends on the wealths of the two parties. The dynamic correction is driven by counterparty risk. If both parties are fairly risk tolerant, in the sense that 2>R>r, then the Proposer takes on more risk than she would under the myopic benchmark. If both parties are fairly risk averse, in the sense that R>r>2, then the Proposer takes on less risk than she would under the myopic benchmark. In the mixed case, in which R>2>r, the Proposer takes on more risk when the Responder's share in total wealth is low and less risk when the Responder's share in total wealth is high. In the case of the approximation for the optimal termination payment, the myopic benchmark is zero. The dynamic correction tells us, among other things, that: (i) if the asset has a high return then, following termination, the Responder compensates the Proposer for the loss of a valuable investment opportunity; and (ii) if the asset has a low return then, prior to termination, the Responder compensates the Proposer for the low returns obtained. Finally, we exploit our representation of the optimal contract to derive simple and easily interpretable sufficient conditions for the existence of an optimal contract"--National Bureau of Economic Research web site

The case-notes of all the 92 patients compulsorily detained under the Mental Health Act from 1st October 1982 - 31st December 1983 were examined retrospectively to deter mine the reasons for transfer to a high Security Unit. Young adult male schizophrenics who were unemployed predominated. Aggressive behaviour was associated with transfer but there was no such relationship with formal diagnosis. Lack of co-operation of the patient was seen more frequently in ethnic minority patients and may be a factor in influencing a trend towards ethnic minority patients being over populated on the unit. The reasons and implications of these findings are discussed.
