Six causes of the credit crunch

Bank lending typically moves with the business cycle. In Texas from 1987 to 1992, however, bank loans declined while nonagricultural employment rose. Robert T. Clair and Paula Tucker consider this evidence of a constrained supply of bank loans, or credit crunch. ; Clair and Tucker find that multiple factors have reduced banks' willingness and ability to supply loans. The resolution of failed banks and thrifts, tightening of bank examination standards, new capital requirements, new regulations and increased enforcement of old regulations, and increased exposure to lawsuits have each had an effect. Many of these regulatory changes where made to address important economic and social goals, but their side effects, often unintended and perhaps unavoidable, have been to reduce bank lending in the short run.Credit

Who Should I Marry: Advice from Parents

When getting married people may worry about whether their parents will approve of their choice in a spouse. On the other hand, parents may want to be involved in their children’s choice. This study was centered on the question: Is there a correlation between adult children’s perceptions and feelings about their parents and their willingness to accept parental advice on marriage choices? A sample of 248 university students completed a set of questionnaires that measured their willingness to accept parental marriage advice, their overall feelings about their parents, and the health of their family relationships. Willingness to accept parental marriage advice was significantly correlated with parental perceptions and family relationships. The more positive participants felt about their parents and the healthier their family relationships, the more willing they were to accept parental marriage advice

Exceptional covers and bijections on rational points

We show that if f: X --> Y is a finite, separable morphism of smooth curves defined over a finite field F_q, where q is larger than an explicit constant depending only on the degree of f and the genus of X, then f maps X(F_q) surjectively onto Y(F_q) if and only if f maps X(F_q) injectively into Y(F_q). Surprisingly, the bounds on q for these two implications have different orders of magnitude. The main tools used in our proof are the Chebotarev density theorem for covers of curves over finite fields, the Castelnuovo genus inequality, and ideas from Galois theory.Comment: 19 pages; various minor changes to previous version.
