Ebook Geology Of The Crater Of Diamonds State Park And Vicinity, Pike County, Arkansas
Submitted by wulan on Tue, 07/28/2009 - 04:01The Crater of Diamonds State Park is remarkable in several ways. First, it is the only place in the world where anyone may pay a small entrance fee, look for diamonds, and keep what you find! It fascinates geologists because the site presents a window into the geologic past and the earth’s mantle, a rare thing indeed. The park and surrounding area has a rich verbal and written history…history of the settlement of the region, of the discovery of diamonds, of the many attempts at commercial and tourist development based on the presence of that gemstone, and history of preservation and continued development since it became a state park and, as such, public property.
This publication is written to accompany the geologic poster by the Arkansas Geological Survey entitled “Geology of the Crater of Diamonds State Park and Vicinity, Pike County, Arkansas.” The reader can learn a lot of geology and geologic history pertaining to the sedimentary and igneous rocks of the area, and specifically of the Park, from the poster and even more by reading the contained information.

Ebook Production Modes in China’s Venture Capital Finance Sector: An Empirical Study on Stage Financing in China
Submitted by puput on Sat, 07/31/2010 - 06:20Entrepreneurial R&D activities are vitally important for innovation, and, consequently for economic development. However, it is very hard to finance young R&D-oriented companies due to the pronounced information asymmetry problems and institutional issues. Venture capital investment has been recognized as one of the most effective ways in dealing with the agency problems associated with R&D financing and promoting innovation. Many nations started to imitate the ‘Silicon Valley Model’ since the mid-1980s with the expectation to stimulate entrepreneurial R&D activities. Nonetheless, the development of the venture capital markets is far from homogeneous around the world, and, even within the United States. This phenomenon raises extensive interests from researchers to find out the factors that affect the outcomes of transplanting venture capital investment to different countries.
The role of institutions played on financial activities has long been debated in the literature. Some researchers suggest that the differences in institutions, especially the divergence in financial and legal systems, are the major factors that impact on corporate performance and business behaviors across countries (La Porta et al., 1997, 1998; Allen & Gale, 1999; Rajan&Zingales; 2003). From cross country studies, it is known that VCs’ investment behaviors depend on the institutions of the countries where they operate. Researchers suggest that stronger institutions lead to more active VCs’ involvements in the management of their portfolio companies and more usage of innovative governance mechanisms, and, consequently lead to more developed venture capital markets (Kaplan et al., 2003; Cummings et al., 2003; Jeng and Wells, 2000).

Ebook Quantity Adjustment Costs and Price Rigidity
Submitted by wulan on Sat, 02/20/2010 - 08:40In recent years a widespread explanation for price rigidity has been lump-sum costs of changing nominal prices, the socalled menu costs. As the name suggests these costs are considered to be small, but shown to have real effects in Mankiw (1985) and Blanchard and Kiyotaki (1987) among others.
The key point is that the loss of not adjusting prices to a given shock is only of second order smallness for the individual agent, whereas the aggregate effect is of first order. This also indicates that because it is not optimal for the single price setter to change its price, the price level may be rigid, and the shock (for instance a demand shock) may affect output causing real effects on welfare. The welfare consequenses of menu costs have been dealt with quite extensively. For an thorough and very good overview see Andersen (1994).
