ECONOMIC ANALYSIS IN THE MAINTENANCE,REPAIR, AND OVERHAUL INDUSTRY: AN OPTIONS APPROACH

This paper presents a practical case application of the real options framework to a multi-stage investment in the aerospace maintenance, repair, and overhaul (MRO) industry. With the deregulated commercial airline industry and military procurement reform, the $44 billion MRO sector must implement tools to remain strategically poised. In this case study, the MRO participant values a multi-stage irreversible expenditure in maintenance equipment and processes under air travel demand uncertainty using a real options analysis. The investment scenario is viewed from a delay, growth, and compound options framework, and an appropriate sensitivity analysis is performed. The main contribution of this paper is the detailed real option framing, valuation, and discussion that may be used as an illustration for industry practitioners or classroom instruction.     

Risk and Return on Real Estate: Evidence from Equity REITs

We analyze monthly returns on an equally weighted index of eighteen to twenty-three equity (real property) real estate investment trusts (REITs) that were traded on major stock exchanges over the 1973–87 period. We employ a multifactor Arbitrage Pricing Model using prespecified macroeconomic factors. We also test whether equity REIT returns are related to changes in the discount on closed-end stock funds, which seems plausible given the closed-end nature of REITs.
Three factors, and the percentage change in the discount on closed-end stock funds, consistently drive equity REIT returns: unexpected inflation and changes in the risk and term structures of interest rates. The impacts of these variables on equity REIT returns is around 60% of the impacts on corporate stock returns generally. As expected, the impacts are greater for more heavily levered REITs than for less levered REITs. Real estate, at least as measured by the return performance of equity REITs, is less risky than stocks generally, but does not offer a superior risk-adjusted return and is not a hedge against unexpected inflation.     

Big Six auditors and audit quality: The Korean evidence

This study investigates the association between discretionary accruals and Big Six and non-Big Six auditors, and the direction of auditor change. We hypothesize that there is no significant difference in discretionary accruals between Big Six and non-Big Six clients when there is low incentive for auditors to provide high-quality audits, as in Korea.Upon examination of the discretionary accruals of firms listed on the Korean Stock Exchange from 1994 to 1998, we find there is no significant difference between the discretionary accruals of firms with Big Six and non-Big Six auditors. This holds true for firms that switch from non-Big Six to Big Six auditors and vice versa. These resources imply that there may be no difference in audit quality between Big Six and non-Big Six auditors in Korea. This is consistent with other studies in Korea, while inconsistent with the findings of previous studies on audit quality in other countries.     

Trade and Financial Integration in East Asia: Effects on Co‐movements

In this paper we explore three important areas where deeper trade and financial integration in East Asia can influence: (1) business cycle co‐movements in the region, (2) the extent of risk sharing across countries and (3) price co‐movements across countries. We find evidence that trade integration enhances co‐movements of output but not of consumption across countries. Especially the fact that trade integration does not raise co‐movements of consumption as much as that of output is interpreted as trade integration does not improve the extent of risk sharing. Co‐movements of price arise most significantly as trade integration deepens, lowering the border effects and allowing better opportunities for resource reallocation across countries. In contrast, financial integration demonstrates much weaker evidence of enhancing co‐movements across countries. Deeper financial integration improves price co‐movements weakly but does not enhance output or consumption co‐movements at all. However, since the current level of financial integration in East Asia is quite low, our evidence is too early to firmly determine the role of financial integration.     

FOREIGN TRADE, COMMERCIAL POLICIES AND THE POLITICAL ECONOMY OF THE SONG AND MING DYNASTIES OF CHINA

The paper presents a framework to explore the trade-off between pro-authority and pro-efficiency foreign trade policy. The former is exemplified by the tributary foreign trade system in Imperial China, while the latter by the government-supervised private foreign trade. In the Song Dynasty (960–1276), a strong external enemy compelled the monarchy to choose a pro-efficiency trade policy to finance the army, whereas during the early Ming Dynasty (1368–1644) when China was strong a pro-authority trade policy was favoured. During the late Ming, as the dynasty weakened, accompanied by external threats and internal mismanagement, the imperial government once again chose a pro-efficiency trade policy.     

Mesenteric actinomycosis

We report a case of abdominal actinomycosis demonstrated on computed tomography (CT) as an isolated mesenteric mass with radiating linear and nodular densities. The lesion mimicked a mesenteric tumor with desmoplastic reaction. The clinical and radiological features of this uncommon entity are reviewed.     

An exploratory investigation of the firm size effect

We investigate the firm size effect for the period 1958 to 1977 in the framework of a multi-factor pricing model. The risk-adjusted difference in returns between the top five percent and the bottom five percent of the NYSE firms is about one to two percent a year, a drop from about twelve percent per year before risk adjustment. The variable most responsible for the adjustment is the sensitivity of asset returns to the changing risk premium, measured by the return difference between low-grade bonds and long-term government bonds.

The role of renqing in mediating customer relationship investment and relationship commitment in China

There is a growing research interest in guanxi marketing, which has been considered the Chinese version of relationship marketing. However, very little empirical research has investigated the implicit nature of renqing, the underlying mechanism that explains the cultivation and maintenance of guanxi. This study examines the role of renqing in mediating customer relationship investment and relationship commitment in the insurance industry. The authors surveyed 245 car insurance policyholders in China. The findings confirm the mediating role of renqing in such relationships and show that renqing explains a very high proportion of the variance in levels of customer relationship commitment. This result offers valuable insights and suggestions as to how to increase levels of customer relationship commitment in China.
