Bank ownership and efficiency in China: what lies ahead in the world’s largest nation?

China is reforming its banking system, partially privatizing and permitting minority foreign ownership of three of the dominant ‘big four’ state-owned banks. This paper seeks to help predict the effects of this change by analysing the efficiency of virtually all Chinese banks in the years 1994–2003. Our findings suggest the big four banks are by far the least efficient and foreign banks the most efficient while minority foreign ownership is associated with significantly improved efficiency. We present corroborating robustness checks and offer several credible mechanisms through which minority foreign owners can increase Chinese bank efficiency. These findings suggest that minority foreign ownership of the big four is likely to significantly improve performance.foreign banks; efficiency; foreign ownership

Simulated Annealing for Location Area Planning in Cellular networks

LA planning in cellular network is useful for minimizing location management cost in GSM network. In fact, size of LA can be optimized to create a balance between the LA update rate and expected paging rate within LA. To get optimal result for LA planning in cellular network simulated annealing algorithm is used. Simulated annealing give optimal results in acceptable run-time.Comment: 7 Pages, JGraph-Hoc Journa

Further evidence on the link between finance and growth: An international analysis of community banking and economic performance

We seek to contribute to both the finance-growth literature and the community banking literature by testing the effects of the relative health of community banks on economic growth and investigating potential transmission mechanisms for these effects using data from 1993–2000 on 49 nations. Data from both developed and developing nations suggest that larger market shares and higher efficiency rankings for small, private, domestically owned banks are associated with better economic performance, and that the marginal benefits of larger shares are greater when the banks are more efficient. Only mixed support is found for hypothesized transmission mechanisms through improved financing for SMEs or greater overall bank credit flows. The data from developing nations is also consistent with favourable economic effects from foreign-owned banks, but unfavourable effects from state-owned banks.banks, community banking, SMEs, financial development, economic growth, international

Helical motion of magnetic flux tubes in the solar atmosphere

Photospheric granulation may excite transverse kink pulses in anchored vertical magnetic flux tubes. The pulses propagate upwards along the tubes with the kink speed, while oscillating wakes are formed behind the wave front in a stratified atmosphere. The wakes oscillate at the kink cut-off frequency of stratified medium and gradually decay in time. When two or more consecutive kink pulses with different polarizations propagate in the same thin tube, then the wakes corresponding to different pulses may superimpose. The superposition sets up helical motions of magnetic flux tubes in the photosphere/chromosphere as seen by recent Hinode movies. The energy carried by the pulses is enough to heat the solar chrmosphere/corona and accelerate the solar wind.Comment: Accepted in ApJ
