Some sufficient conditions for the recurrence, the positive recurrence and the exponential ergodicity of one-dimensional Lévy type operators are presented. The conditions are classified according to different conditions on the ranges and integrability of the Lévy measure, based on the drift...

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.

By using the existing sharp estimates of the density function for rotationally invariant symmetric [alpha]-stable Lévy processes and rotationally invariant symmetric truncated [alpha]-stable Lévy processes, we obtain that the Harnack inequalities hold for rotationally invariant symmetric...

We estimate exchange rate pass-through (PT) into import, producer and consumer price indexes for nine OECD countries, using a method proposed by Uhlig (2005). In a Vector Autoregression (VAR) model, we identify the exchange rate shock by imposing restrictions on the signs of impulse responses...

The U.S. current account deficit has deepened significantly since the late 1990s. This shortfall—the value of net exports of goods and services, international financial investment net income and transfer payments—was $803 billion at its peak in 2006, or 6 percent of U.S. gross domestic...

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.

After Xiao et al. [W.-K. Xiao, J. Ren, F. Qi, Z.W. Song, M.X. Zhu, H.F. Yang, H.Y. Jin, B.-H. Wang, Tao Zhou, Empirical study on clique-degree distribution of networks, Phys. Rev. E 76 (2007) 037102], in this article we present an investigation on so-called k-cliques, which are defined as...

The paper is a continuation of our paper, Wang and Wang (2013) [13], Chen and Wang  [4], and it studies functional inequalities for non-local Dirichlet forms with finite range jumps or large jumps. Let α∈(0,2) and μV(dx)=CVe−V(x)dx be a probability measure. We present explicit and sharp...
