Option pricing in the presence of natural boundaries and a quadratic diffusion term

This paper uses a probabilistic change-of-numeraire technique to compute closed-form prices of European options to exchange one asset against another when the relative price of the underlying assets follows a diffusion process with natural boundaries and a quadratic diffusion coefficient. The paper shows in particular how to interpret the option price formula in terms of exercise probabilities which are calculated under the martingale measures associated with two specific numeraire portfolios. An application to the pricing of bond options and certain interest rate derivatives illustrates the main results.     

State appropriations and undergraduate borrowing: more debt,less money

When state appropriations decrease, public universities respond by raising tuition. Students borrow more in response to both tuition increases and appropriation cuts. This article investigates the feedback of how borrowing and tuition influence state appropriations. Using a panel data set of 450 four-year public universities from 1999 to 2012, we employ three-stage least squares techniques to control for the endogeneity between state appropriations, tuition and student borrowing. There is evidence that state policy-makers respond to increases in university tuition and student borrowing by decreasing future appropriation levels. After controlling for the effect of appropriations on tuition and borrowing, a one-dollar increase in student borrowing reduces state appropriations per student by $0.06, and a one-dollar increase in tuition results in a decrease of $0.45 in state appropriations per student. When universities increase tuition for reasons other than a reduction in state appropriations, policy-makers respond with a significant cut in future appropriations which could signal an incentive strategy.     

A model of adjuncts in higher education

We examine the phenomenon of the expanded use of non-tenure-track positions (“adjuncts”) and construct a supply-side Harris–Todaro model. Low adjunct wages are attributable to a “Hope Rent” from the gap between private opportunities and tenure-track utility.     

关于提高高等数学教学质量的几个途径

随着高校的不断扩招,一般院校（特别是边远地区院校）的生源质量在逐年下降.如何提高高等数学教学质量,这是我们每一个高校数学教育工作者面临的新问题.注重初、高等数学知识与方法的衔接,实施分级教学,消除非智力因素对学习高等数学的影响是提高高等数学教学质量的几个有效途径.
