Call blockage may incur large losses in areas prone to traffic accidents. We formulate an optimisation problem that chooses base station locations and assign channels to them so as to minimise the overall installation and call blockage costs. Since this problem is a difficult non-linear integer...

This paper evaluates the sustainability of large current account imbalances in the era when the Chinese GDP growth rate and current account/GDP exceed 10%. We investigate the size distribution and the durability of current account deficits during 1966-2005, and report the results of a simulation...

This paper studies the degree to which Emerging Markets (EMs) adjusted to the global liquidity crisis by drawing down their international reserves (IR). Overall, we find a mixed and complex picture. Intriguingly, only about half of the EMs relied on depleting their international reserves as part...
