Aiming at developing exhaust gas-driven automobile air conditioners, two types of systems varying in heat carriers were preliminarily designed. A new hydride pair LaNi4.61Mn0.26Al0.13/La0.6Y0.4Ni4.8Mn0.2 was developed working at 120–200°C/20–50°C/−10–0°C. P-C isotherms and reaction...

The authors present a theoretical derivation of cigarette demand and estimate the demand in Japan with prefecturE-level data. By examining the impact of information dissemination regarding the health hazards of smoking, the authors argue that information dissemination is an effective instrument...

In the last few decades, the telecommunications industry has experienced dramatic technological change. However, since divestiture of AT&T, there have been only a few studies that estimate the effects of technological change. Using a cost function, we estimate these effects. Unlike previous...

In this paper, precise fault location in electrical traction network systems is discussed in the high-frequency domain. Based on the analysis of the equivalent impedance at the measurement terminal, the relationship between the fault distance and the frequency spectrum extreme points of the...

In this paper, methods of fault location are discussed in electrical traction single-end direct power supply network systems. Based on the distributed parameter model of the system, the position of the short-circuit fault can be located with the aid of the current and voltage value at the...

This paper proposes an option-based portfolio insurance method for international foreign exchange risk hedging. Each investor is assumed to maximize the expected utility of his/her portfolio which includes international risky assets and foreign currency index derivatives. The optimal investment...

This paper characterizes the co-movements in commodity prices with a dynamic latent factor model that decomposes commodity returns into global, sectoral, and idiosyncratic components. The results indicate that global and sectoral factors are important sources of co-movements in commodity...

Using a new uncertainty index from Baker <italic>et al</italic>. (2013), we evaluate the time-varying correlation between macroeconomic uncertainty and commodity prices. Estimation results from a multivariate DCC-GARCH model reveal that increased volatility in uncertainty leads to increased price and volatility...

Using the forecast error variance decomposition from a vector auto-regression, this article examines both average and time-varying spillovers of macroeconomic uncertainty across major economies since 1997 and compares the ongoing crisis with earlier episodes. We show that spillover effects of...
