Volume of a doubly truncated hyperbolic tetrahedron
The present paper regards the volume function of a doubly truncated
hyperbolic tetrahedron. Starting from the previous results of J. Murakami, U.
Yano and A. Ushijima, we have developed a unified approach to express the
volume in different geometric cases via dilogarithm functions and to treat
properly the many analytic strata of the latter. Finally, several numeric
examples are given.Comment: Several misprints in the proof of Theorem 1 correcte
Does social capital affect the financing decisions of Chinese small and medium-sized enterprises?
Using a panel of 65,551 firms over the period 2000-2006, this study examines the capital structure determinants of Chinese privately owned small and medium-sized enterprises. Investment in the building and maintenance of social capital, measured by entertainment expenditure, is found to be positively associated with short-term leverage, but negatively associated with long-term leverage, while the opposite is the case for asset structure. This suggests that social capital is important for firms who seek to establish initial relationships with their financiers, while asset structure is more important in the consolidation of these relationships.Capital structure, China, leverage, social capital
