地方政府税收竞争对产能过剩的影响

使用2001—2011年我国省际面板数据,测算了我国30个省(自治区、直辖市)的产能过剩程度,进一步实证检验了地方政府的税收竞争对产能过剩的影响。结果表明:产能过剩主要出现在重工业领域;地方政府的税收竞争加剧了重工业的产能过剩程度,其中增值税竞争的影响大于总税收竞争和企业所得税竞争的影响,地方政府税收竞争的滞后影响大于当期影响;在中、西部地区,地方政府的税收竞争对重工业产能过剩的影响更为显著。指出:减弱地方政府的税收竞争有利于缓解我国产能过剩问题。     

基于三角模糊数的贷款组合优化模型比较分析

随着中国利率市场化的进程,贷款利率呈现出更大的不确定性,商业银行间的竞争也越来越激烈,在新的行业特点和经营形势下,商业银行需要结合研究贷款资源的配置方式,为商业银行管理层的决策提供有力的支撑。引入三角模糊数来刻画商业银行的收益率,并利用其可能性均值来构建三类贷款组合优化模型进行分析,结果显示模型的有效边界都符合均值方差模型有效边界的变化趋势,且得到的贷款权重配置可以更好地体现贷款利用效率。     

利用粉煤灰合成A型沸石分子筛的实验研究

以烟台某电厂排放的粉煤灰固体废弃物为原料,对原料进行预处理及水热合成实验合成出沸石分子筛,经XRD表征可知产物为A型分子筛。通过试验确定最佳合成条件:焙烧温度为750℃、碱度比为1.3、晶化温度为100℃以及晶化时间为10 h。在此条件下合成的沸石结晶度较高,具有很好的应用前景。

Temporary Equilibrium,Full Equilibrium,and Elasticity of Cost

The result by Morrison (1985) and Morrison and Schwarzt (1994) that there is an one-to-one relationship between the rate of economic capacity utilization and ratio of cost elasticities at the temporary and the full equilibrium has been instrumental in past studies on measuring economic capacity utilization and on adjusting indexes of productivity growth for temporary equilibrium. In this paper, dynamic duality and comparative dynamics are employed to assess the behavior of cost elasticity along an optimal path to the steady state. The analysis suggests that no a priori relationship exists between economic capacity utilization and elasticity of cost. The absence of an a priori relationship between these two economic variables implies that theoretical and empirical results based on past notions about the dynamic behavior of cost elasticity may have to be reconsidered.

A NEW METHOD FOR THE ESTIMATION OF CAPACITY UTILIZATION: THEORY AND EMPIRICAL EVIDENCE FROM 14 EU COUNTRIES

In this paper, we develop a new and at the same time simple method of obtaining a measure of the rate of capacity utilization (CU) which makes use of the structural vector autoregression (SVAR) system of equation estimating technique with long‐run restrictions. The measure of CU that we derive for each of 14 EU countries replicates to a great extent the European Commission's Directorate General for Economic and Financial Affairs (ECFIN) measure. On closer examination we find that the in‐sample explanatory content with respect to the inflation rate of the SVAR measure exceeds more often than not that of the ECFIN's measure; however, the out‐of‐sample forecasting performance of the two models is approximately equivalent.     

Improving the estimation of total factor productivity growth: capital operating time in a latent variable approach

Measuring labor and capital services accurately is essential to obtaining reliable estimates of production functions and total factor productivity (TFP) growth. Using data on the operating time of capital, a series that exists for the French business sector, greatly improves the measurement of effective capital services in production. The ensuing estimation results are consistent with Cobb–Douglas technology under constant returns to scale, with the factor elasticities not statistically different from their income shares. In the same framework, TFP growth is estimated as a latent variable and found to be less volatile than accounting residuals, negatively correlated with employment, and free of cyclicality. It is statistically best estimated as a first-order autoregressive process, with an autoregressive coefficient of 0.95. Total factor productivity growth was estimated to have declined steadily between the mid-1970s and mid-1990s, but the rate of decline has diminished since then.
