School finance reform: Assessing general equilibrium effects

In 1994 the state of Michigan implemented one of the most comprehensive school finance reforms undertaken to date in any of the states. Understanding the effects of the reform is thus of value in informing other potential reform initiatives. In addition, the reform and associated changes in the economic environment provide an opportunity to assess whether a simple general equilibrium model can be of value in framing the study of such reform initiatives. In this paper, we present and use such a model to derive predictions about the effects of the reform on housing prices and neighborhood demographic compositions. Broadly, our analysis implies that the effects of the reform and changes in the economic environment are likely to have been reflected primarily in housing prices and only modestly on neighborhood demographics. We find that evidence for the Detroit metropolitan area from the decade encompassing the reform is largely consistent with the predictions of the model.     

Constitutional Constraints on Governments in a Global Economy

The continuing integration of Europe, the increasing mobility of its citizens and enterprises, and the globalization of the world economy place increasing pressure on Europe's redistributive regulations, taxes, and subsidies. The most attractive response for many European governments is to reduce the options of its citizens through tax and regulation harmonization, thereby avoiding the politically costly steps of taking away the subsidies and privileges to which the politically most powerful groups are accustomed. The danger Europe faces by responding to the pressure from globalization by tax harmonization, however, is that it preserves the resulting inefficiencies, and becomes increasingly unattractive for businesses to locate, people to work, and eventually for people to live.This paper examines the cases for a redistributive state and an allocative (efficiency) state from the perspective of constitutional political economy. A constitutional democracy is described in which the state engages in those sorts of redistribution that all people favor, and provides only those goods, services and regulations that make all citizens better off.     

Optimal No‐Arbitrage Bounds on S&P 500 Index Options and the Volatility Smile

This article shows that the volatility smile is not necessarily inconsistent with the Black–Scholes analysis. Specifically, when transaction costs are present, the absence of arbitrage opportunities does not dictate that there exists a unique price for an option. Rather, there exists a range of prices within which the option's price may fall and still be consistent with the Black–Scholes arbitrage pricing argument. This article uses a linear program (LP) cast in a binomial framework to determine the smallest possible range of prices for Standard & Poor's 500 Index options that are consistent with no arbitrage in the presence of transaction costs. The LP method employs dynamic trading in the underlying and risk‐free assets as well as fixed positions in other options that trade on the same underlying security. One‐way transaction‐cost levels on the index, inclusive of the bid–ask spread, would have to be below six basis points for deviations from Black–Scholes pricing to present an arbitrage opportunity. Monte Carlo simulations are employed to assess the hedging error induced with a 12‐period binomial model to approximate a continuous‐time geometric Brownian motion. Once the risk caused by the hedging error is accounted for, transaction costs have to be well below three basis points for the arbitrage opportunity to be profitable two times out of five. This analysis indicates that market prices that deviate from those given by a constant‐volatility option model, such as the Black–Scholes model, can be consistent with the absence of arbitrage in the presence of transaction costs. © 2001 John Wiley & Sons, Inc.

Ecomagination — Ein Unternehmen positioniert sich nachhaltig

Zusammenfassung  Nachhaltigkeit hat sich zu einer Art Mantra für das 21. Jahrhundert entwickelt. Damit steigt für Unternehmen der Erkl?rungsbedarf gegenüber der ?ffentlichkeit: Wie nachhaltig ist ihr eigenes wirtschaftliches Handeln? Verantwortungsbewusster Umgang mit natürlichen Ressourcen wird zunehmend zu einer Herausforderung von existenzieller Bedeutung. Unternehmen sollten die eigene Positionierung an diese Entwicklungen anpassen. Ein Beispiel für eine erfolgreiche Nachhaltigkeitspositionierung ist das Umweltengagement von General Electric.     

Mentoring and Practical Wisdom: Are Mentors Wiser or Just More Politically Skilled?

Mentoring is a natural setting for senior employees to render ethics advice and consultation to junior employees. Two studies examined the question of whether those who mentor are more practically wise than those who do not. Although four different measures of practical wisdom were used, no differences were detected. However, mentors were shown to be more politically skilled than non-mentors.     

An Economic Analysis of Housing Abandonment

Landlord abandonment of rental housing has affected many American cities since the 1960's. Because of data limitations, there have been few empirical analyses of the determinants of housing abandonment. In this paper, we use a rich database that contains information on individual residential properties in New York City to estimate a reduced form model of owner abandonment. We model an owner's decision to abandon his or her property as being similar to an investor's decision to exercise a put option on a financial instrument. When required to pay delinquent taxes, a wealth-maximizing landlord has an incentive to cede ownership of his or her residential property when the value of all outstanding liens exceeds the property's market value. Estimates from the model are used to examine whether empirical evidence supports this option model of abandonment.
