Real interest parity: A note on Asian countries using panel stationarity tests

Existing panel data studies of real interest parity are either unable to identify which panel members are characterised by stationary real interest differentials, or are subject to size distortion resulting from the presence of structural breaks and cross-sectional dependencies. Using a panel stationarity testing procedure recently advocated by Hadri and Rao (2008) that allows for structural breaks and cross-sectional dependency, we are unable to reject the stationarity of Asian real interest rate differentials.     

Does purchasing power parity hold in African less developed countries? Evidence from a panel data unit root test

This study tests for long-run relative purchasing power parityamong a sample of 27 African less developed countries. For thispurpose, a new test advocated by Im and co-workers is employedwhich allows one to test for unit roots in heterogeneous paneldatasets. This is known as the t-bar test, by which purchasingpower parity is confirmed or rejected on the basis of whetheror not the average augmented Dickey-Fuller statistic based ondemeaned data is significantly different from zero. Using quarterlydata covering the period 1974-97, purchasing power parity isgenerally rejected using individual country unit root testsbut support is found using the t-bar test. This suggests thatlow power problems in testing for purchasing power parity canbe overcome using this panel data procedure. The findings alsosupport the view that purchasing power parity is most likelyto be found among high inflation less developed countries andthat the half-life of a one-off random shock to parity is approximatelysix quarters. These results are generally confirmed for the1960-73 period.     

The Velocity of Circulation: Some new evidence on international integration

This study tests for the integration of money velocity movements among the major European Union countries. For this purpose, a new test is employed that allows one to confirm or reject integration on the basis of whether or not the first largest principal component, based on deviations of velocity growth rates from a base country, is stationary. Using monthly data covering the last 25 years, this study finds that integration was strongest during the 1970s and during 1983-92. These findings modify the institutionalist view that common financial developments have meant that velocities have moved together on an upward secular trend over the last 40 years. Developments with regard to currency substitution along with exchange rate policy and capital controls can affect relative interest rates and income movements and therefore the co-movements in money velocities.     

Real interest rates,inflation and the open economy: A regime-switching perspective on Australia and New Zealand

We investigate the time-series properties of Australian and New Zealand real interest rates within a Markov-switching framework. This enables us to identify characteristics in real interest rate behavior hitherto unacknowledged. We find that rates switch between alternative stationary regimes characterized by differing means, speeds of mean-reversion and volatility. For New Zealand, high rates of inflation increase the probability of remaining in a regime characterized by a faster speed of adjustment. Further application of this methodology considers the real interest rate differential between Australia and New Zealand and points to differing regimes based on volatility rather than persistence.     

Airline Schedule Recovery after Airport Closures: Empirical Evidence since September 11

Since the September 11, 2001, terrorist attacks, repeated airport closures due to security breaches have imposed substantial costs on travelers, airlines, and government agencies in terms of flight delays and cancellations. Using data from the year following September 11, this study examines how airlines recover flight schedules upon reopening of airports that have been closed for security reasons. As such, this is the first study to empirically examine service quality during irregular airport operations. Our results indicate that economic considerations, particularly the potential revenue per flight, have predictable effects on service quality following airport closures. Airport concentration, hub destination, and various logistical factors also significantly influence flight outcomes.     

The Ethics of Professorial Book Selling: Morality, Money and "Black Market" Books

This study used experimental and correlational techniques to examine perceptions that university faculty hold regarding the practice of professorial selling of examination textbooks to wholesalers. Faculty members (n = 236) from 14 universities and community colleges and a wide variety of academic disciplines responded to a web-based survey. We presented hypothetical selling situations to respondents with manipulated variables consisting of solicitation status (unsolicited versus solicited) and use of money (for faculty or for student activities). Both main effects and the interaction effect were significant such that respondents perceived it to be more ethical to sell an examination book when the book was unsolicited and when the money was being used to fund student activities. The variable most correlated with faculty members' beliefs that book selling is ethical and the faculty members' self-reports of whether or not they have engaged in bookselling was how widespread the practice appeared to be on campus. About 30 percent of faculty members sold textbooks over the past year at a dollar value of about $80 per professor. About 38 percent of respondents reported they believed the practice to be generally ethical. Implications for business ethics theory, students' moral development, and advancement of on-campus codes of ethics policies are discussed along with avenues for future research.     

Gender and graduate economics education in the US

Abstract

This paper reports on the findings of a survey of top economics graduate schools as they relate to women and men. The results provide strong evidence that at these top graduate schools, women graduate students are less integrated in their economic disciplines than are male graduate students. In the second part of the paper, this paper relates those findings to alternative theories as to why this is the case. This paper concludes by suggesting that the emphasis on theoretical studies in the current core of the graduate economics program can be seen as a type of hazing process that seems to have a significant cost since many women (and men) with great creative promise are discouraged from continuing in economics and do not benefit nearly as much as they would have from more policy-driven core courses.
