关于影响农业生产经营风险因素的实证分析

在农业生产领域中存在许多非人为的风险及人为因素可以克服或降低的风险,对于前者,我们可能很难解决,但是对于后者,我们可以采取相关的措施来预防与降低农业生产经营风险。具体到本文,主要通过对影响农业生产经营风险的两大因素,即农业投入与农业技术的实证分析,从而为降低农业生产经营风险提供政策导向。

The benefits of non-radial vs. radial super-efficiency DEA: an application to burden-sharing amongst NATO member nations

Using radial super-efficiency data envelopment analysis (DEA) has improved the discriminating performance across efficient decision-making units (DMUs). This paper extends the super-efficiency approach to a non-radial super-efficiency DEA (NRSE-DEA) index. NRSE-DEA is shown to be invariant to units of input (output) measurement. NRSE-DEA is illustrated here via an application to NATO burden-sharing assessment in which the DMUs are the member nations of NATO. The NRSE-DEA provides additional insights into the ranking of efficient countries, suggesting which are absorbing a particularly large share of NATO responsibilities. The NRSE-DEA generates a smaller set of efficient DMUs. This, in turn, provides more discriminatory power, a more accurate measure of super-efficiency, a more meaningful ranking of the efficient burden sharing countries, and a more reliable assessment of contributions by NATO members, amongst other policy issues.

试析民族自治地方教育财政自治的基本内涵

财政自治与教育财政自治同属于我国民族自治地方依法享有的民族自治权利.由于我国多年来教育财政投入的不足,致使民族自治地方的教育自治权难以得到根本保障.本文主要对财政自治与民族教育财政自治的基本内涵进行阐释,并对教育财政自治与财政自治的关系作了分析,以利于对我国教育财政投入和民族教育财政自治问题作进一步研究.     

The Adjustment Property

An input–output (IO) system which is capable of producing any semi-positive net product by an adequate choice of the activity levels of its processes satisfies the ‘adjustment’ property. We analyze under which conditions the adjustment property holds for IO systems in which some produced goods have a purely intermediate character. The peculiarity of these pure capital goods is that final demand for them is identically zero. One of the ways to deal with this type of system is to eliminate the pure capital goods, by means of vertical integration.     

The economic impact of tourism in SIDS

Small Island Developing States (SIDS) are faced with many challenges to economic development. Tourism is seen as a viable, and sometimes, only means of economic growth. This research compares the economic impact of tourism to seven SIDS. The research employs input output analysis, linkage analysis and a CGE model to assess the macroeconomic and sectoral impacts of increased tourism in these islands. The findings show that the transportation sector remains a key sector. The tourism income multipliers show that tourism generates a large amount of economic activity but the income that remains in the destinations is often very small. The results show that taking advantage of economies of scale maybe a way to maximize the benefits from tourism.

New Zealand Bank Mergers and Efficiency Gains

ABSTRACT

This paper uses accounting ratios and DEA (Data Envelopment Analysis) to explore the efficiency impacts of 6 bank mergers in New Zealand between 1989 and 1998. The paper is the first reported application of DEA to the New Zealand banking sector, and its methodology is based around that used by Avkiran in his study published in the Journal of Banking and Finance in 1999 (Avkiran, 1999b).

Consistent with earlier research, acquiring banks were found to be generally larger than their targets, although they were not consistently more efficient. In a majority of cases the merger led to an increase in efficiency, consistent with a trend observed for the banking sector as a whole. No clear conclusions could be drawn on possible public benefits from the mergers.
