We investigate the impact of the introduction and exit of EnronOnline on the efficiency of the U.S. natural gas market. In particular, we examine the natural gas market informational efficiencies by investigating the time-series properties of natural gas prices: changes in natural gas price...

We studied the market performance at selected, representative natural gas trading hubs in the U.S. and documented different price behaviors among various hubs. With NYMEX prices as the competitive benchmark, we found empirically that the spot price responses at some trading hubs were...

This paper examines the welfare implications of different exchange-rate systems, especially an exchange-rate target-zone system, in a context of monetary policy making and dynamic inconsistency. It is shown that when there is uncertainty, there is a trade-off between commitment to a rule and...

Given the discrete nature of the outward foreign direct investment (FDI) data, the count data regression models are set up as vehicles for our empirical work. We propose and test various econometric specifications that address the main problems inherent in the traditional Poisson regression....

There is a debate on the excess volatility of long-term bond yields. It is found that whether long-term bond yields are excessively volatile or excessively smooth depends critically on the knowledge of the long-run properties of the short-term interest rate process. Uses a span of 200 years of...

The fragmentation of production across countries has become an important feature of the globalization in recent decades and is often conceptualized by the term, global value chains (GVCs). When empirically investigating the GVCs, previous studies are mainly interested in knowing how global the...

This study examines the short‐term volatility of natural gas prices through an examination of the intraday prices of the nearby natural gas futures contract traded on the New York Mercantile Exchange. The influence on volatility of what many regard as a key element of the information set...

Exfoliated graphite nanoplatelets (xGnP) were applied to enhance the thermal conductivity of polyaniline (PANI) based form-stable phase change materials (PCMs). The xGnP was first dispersed in palmitic acid (PA) uniformly under the assistance of ultra-sonication. The xGnP/PA mixture was then...

Theory of complex networks proved successful in the description of a variety of static networks ranging from biology to computer and social sciences to economics and finance. Here we use network models to describe the evolution of a particular economic system, namely the International Trade...
