The fate of CO2 hydrate disposed of in the ocean is analyzed based on thermodynamic theory. It is found that CO2 hydrate and seawater form a stable system only when (a) the system pressure p and temperature T fall within the hydrate-formation region in the ocean (i.e. p 4.5MPa and T 283 K) and...

This study derives optimal hedging rules for simultaneously minimizing short- and long-term shortage characteristics for a water-supply reservoir. Hedging is an effective measure to reduce a high-percentage single period shortage, but at a cost of more frequent small shortages. Thus...

At the turn of the millenium, most of the APEC countries have embarked upon an ambitious plan for open multilateralism. Using an 18-region, 16-sector dynamic computable general equilibrium (CGE) model of the global economy, we evaluate the effects of APEC trade liberalization on member-country...
