A Ladder Operator Solution to the Particle in a Box Problem

A ladder operator solution to the particle in a box problem of elementary quantum mechanics is presented, although the pedagogical use of this method for this problem is questioned.

The Optimal Capital Structure of Banks: Balancing Deposit Insurance, Capital Requirements and Tax-Advantaged Debt

The capital structure and regulation of financial intermediaries is an important topic for practitioners, regulators and academic researchers. In general, theory predicts that firms choose their capital structures by balancing the benefits of debt (e.g., tax and agency benefits) against its costs (e.g., bankruptcy costs). However, when traditional corporate finance models have been applied to insured financial institutions, the results have generally predicted corner solutions (all equity or all debt) to the capital structure problem. This paper studies the impact and interaction of deposit insurance, capital requirements and tax benefits on a bankÇs choice of optimal capital structure. Using a contingent claims model to value the firm and its associated claims, we find that there exists an interior optimal capital ratio in the presence of deposit insurance, taxes and a minimum fixed capital standard. Banks voluntarily choose to maintain capital in excess of the minimum required in order to balance the risks of insolvency (especially the loss of future tax benefits) against the benefits of additional debt. Because we derive a closed- form solution, our model provides useful insights on several current policy debates including revisions to the regulatory framework for GSEs, tax policy in general and the tax exemption for credit unions.

HACCP Drives Safe Seafood

Seafood is part of a healthy diet, but how can you be sure that the seafood on your plate has not become contaminated somewhere between the boat and your home? HACCP training helps seafood processors and handlers meet FDA regulations to control potential hazards along the way.

2006: A Safe Year for Falls at John Dempsey Hospital!

Our Goal: To Prevent Harm The most important goal for the Collaborative Center for Clinical Care Improvement (C4I) Patient Falls Group is to prevent any serious injury should a fall occur. While our goal is also to reduce the number of patient falls, it is especially important to prevent any serious harm to the patient. During calendar year 2006 (January-December), we accomplished our most important goal - there were no serious injuries related to any patient falls that occurred in the hospital during the past twelve months.
