We construct optimal Markov couplings of Lévy processes, whose Lévy (jump) measure has an absolutely continuous component. The construction is based on properties of subordinate Brownian motions and the coupling of Brownian motions by reflection.

We develop criteria for recurrence and transience of one-dimensional Markov processes which have jumps and oscillate between +[infinity] and -[infinity]. The conditions are based on a Markov chain which only consists of jumps (overshoots) of the process into complementary parts of the state...

Continuous-time random walks are pure-jump processes with several applications in physics, but also in insurance, finance and economics. Based on heuristic considerations, a definition is given for the stochastic integral driven by continuous-time random walks. The martingale properties of the...

A quarter-century quest hasn't found the elusive links between economic fundamentals and currency values. ; The U.S. dollar has been losing value against several major currencies this decade. Since 2001-02, the U.S. currency has fallen about 50 percent against the euro, 40 percent against the...

Two approaches for planning manufacturing strategy, a strategic approach and a paradigmatic approach, are introduced. The key decisions of these two approaches are, respectively, located in the choices of competitive priorities and manufacturing paradigms. Three hypothesis models on the...

Despite the importance of international trade firms in China’s economic development, there is only limited empirical evidence about how these firms assimilate Internet-based e-business in global supply chain operations. Using the Technology-Organization-Environment framework, this study...

China’s economic slowdown and changing demographics cloud its housing market’s long-term prospects. While urbanization and a lack of alternative investment opportunities provide short-run support, the housing sector’s difficulties imperil China’s financial sector and the global recovery.

In accordance with the concept of the agricultural natural disasters formed in China, by means of over 20 years of major disasters occurred panel data of recorded, it defined and measured the rates of disaster reduction and disaster affected, and gives the interpretation of mitigation...
