Classification of derivation-simple color algebras related to locally finite derivations
We classify the pairs consisting of an
-olor-commutative associative algebra with an identity
element over an algebraically closed field of characteristic zero and a
finite dimensional subspace of -color-commutative
locally finite color-derivations of such that is -graded
-simple and the eigenspaces for elements of are -graded. Such
pairs are the important ingredients in constructing some simple Lie color
algebras which are in general not finitely-graded. As some applications, using
such pairs, we construct new explicit simple Lie color algebras of generalized
Witt type, Weyl type.Comment: 15 page
The fiscal framework and urban infrastructure finance in China
China has experienced more than 25 years of extraordinary economic growth. Underlying this growth has been a decentralized fiscal system, in which provinces and large cities are given the freedom to make infrastructure investmentsto stimulate local development, and are allowed to retain a large part of the fiscal revenues that are generated from economic activity. Although successful as a growth strategy, this policy created two problems for national fiscal management. First, it significantly reduced the central government's share of fiscal revenues, which fell from 34.8 percent in 1980 to 22 percent in 1992. Second, it widened economic and fiscal disparities between the rapidly growing urban coastal region and the rest of the country. Rapid growth in subnational debt (which rose 23-fold in a decade) and subnational nonperforming loans (estimated by the authors to range between US150 billion) has placed pressure on China's financial system. Traditionally, China has favored bank lending as a source of finance because the banking system has provided a vehicle for central political control over local debt. But as China's financial system matures, creditworthiness standards must become more important. The authors recommend greater use of the revenue streams from infrastructure assets as a financing source, and gradual relaxation of central political control over subnational debt. One step in this direction would permit leading cities to issue municipal bonds based on objective financial standards.Banks&Banking Reform,Urban Economics,Public&Municipal Finance,Municipal Financial Management,Intergovernmental Fiscal Relations and Local Finance Management
