In this paper, we study the efficiency of the Chinese wheat and soybeans futures markets and assess the conditions in agricultural commodity futures and cash markets in China. Formal statistical tests are conducted through Johansen's cointegration approach to identify the long-term equilibrium relationship between futures and cash markets. Three different cash prices from Zhengzhou Grain Wholes...

To construct a large commodity cluster, a hierarchical network is generally adopted for connecting the host machines, where a Gigabit backbone switch connects a few commodity switches with uplinks to achieve scaled bisectional bandwidth. This type of interconnection usually results in link contention and has congestion developed at the uplink ports. Moreover, the non-deterministic delays on sch...

In spite of the growing computational power offered by the commodity hardware, fast pump scheduling of complex water distribution systems is still a challenge. In this paper, the Artificial Neural Network (ANN) meta-modeling technique has been employed with a Genetic Algorithm (GA) for simultaneously optimizing the pump operation and the tank levels at the ends of the cycle. The generalized GA+...

Since the 2000s, large fluctuations in commodity prices have become a concern among policymakers regarding price stability. This paper investigates the effects of commodity price shocks on headline inflation with a monthly panel consisting of 144 countries. We find that the effects of commodity price shocks on inflation virtually disappear within about one year after the shock. While the effect...

• Commodity price effect is non-uniform and changes over time. Diverse sectoral commodity effects are robust to alternative specifications. affected by crisis third-country exchange rates. The empirical results challenge the assumption of stable effects. Using quarterly data on four commodity-exporting countries, we examine explanatory power real prices predict effective rates, paying particula...

nterest in commodity prices as indicators of consumer price inflation has ebbed and flowed with the rise and fall in commodity prices themselves. True to form, as commodity prices have surged in the last two years (Chart 1), interest in their predictive power has returned. Inflation hawks point to an outpouring of studies in the late 1980s showing a strong empirical connection between commodity...

Bitcoin is one of the crypto currencies which increasingly popular as a digital currency. asset that can be accepted by global modern society nowadays. used in online transactions either for purchase goods or services. This study aims to find out significant relationship between Bitcoin, gold, crude oil, and USD. In addition, this also examines causal exists with each variable, whether bitcoin ...
