We examine investment behavior among exchange-listed Korean manufacturing firms before and after the 1997 financial crisis using firm-level panel data. Starting with the standard Q-theory of investment, we augment it by allowing for a sales accelerator and the possibility of cash constraints, categorizing firms based on their age, size and affiliation to an industrial conglomerate (i.e., chaebol). We find that Tobin’s Q is a robust determinant of investment in a pooled sample for 1992–2001, but that it became more important for small firms and less important for chaebol-affiliated firms after the crisis. Investment by chaebol firms also became more sensitive to the availability of internal cash balances after the crisis. We interpret this as reflecting a shift in the Korean economy to a stronger market orientation after the crisis and to a business climate in which the quality of potential projects became more important relative to capital market imperfections in determining the destination of investment funds.  相似文献

Network neutrality and the nature of competition between network operators   总被引:2,自引:0,他引:2  
The neutral architecture of the Internet is being challenged by various parties, such as network operators providing the connections to end-users, who are interested in gaining control of the information exchanged over the Internet. What are the effects on competition and welfare of such practices? Currently, there exists very little economic theory on network neutrality. This paper provides a preliminary analysis of the type of economic modeling that can address network neutrality, as well as of the type of results that can be expected.  相似文献

This paper examines the efficiency of commercial banks in Namibia using the standard econometric frontier approach. Although two aspects of efficiency (scale and scope) receive our attention, the emphasis is on the latter which pertains to whether a firm produces as efficiently as it possibly can, given its size. Our results indicate that substantial economies of scale exist in commercial banking in Namibia. This will tend to suggest that commercial banks in Namibia can increase their efficiency by increasing their current scale of operation. The results for scope economies show that the current level of input combination does not make for maximum efficiency as sufficient scope exists for a more efficient combination of inputs. We believe this will reduce operating costs in the industry and stimulate efficiency.  相似文献

Financial flows between center and region are analyzed on the example of the Republic of Buryatia. Significant changes are shown to have occurred in the interbudgetary relations between the federal center and the region, which are associated with a revised delineation of authorities between different levels of authority. It has been the key factor in changing the sources and volumes of financial flows. The analysis is largely focused on the relations between the region and its municipalities.  相似文献
