Several consumer studies have shown considerable market potential for sustainable meat products, however, their markets shares are still marginal. In Germany, the sustainable aspects “organic,” “local origin,” and “animal welfare” are of special interest. To obtain a precise overview of potential target groups for these meat categories and their choice of store format, 620 German consumers were surveyed on their attitudes toward sustainable meat production and their shopping behavior. First, target groups based on consumers’ attitudes were identified by cluster analysis, taking into account possible overlaps. Consumers were also clustered by their store format choice and their preferred type of meat packaging. A cross tabulation of the results then provided insights into which store format and type of meat packaging is preferred by the target groups for sustainable meat products. Due to overlaps found in the target groups, the existence of important subgroups was shown. Amongst the target groups, only a slight preference for unpackaged meat products was found. Basically, the offer of sustainable meat products appears of interest for all store formats, with particular emphasis on supermarkets. The results of this study can support producers and retailers developing new and tailored marketing strategies for sustainable meat products. 相似文献

The focus of this paper is twofold. First, it examines the impact on work effort of changes in government purchases financed with lump‐sum taxes, in a neoclassical framework, with respect to four industrialised countries. Second, it reconsiders the expenditure–work effort relationship in a broader conceptual context that allows for distortionary taxation and a disaggregation of the income and substitution effects. Our findings are shown to cast doubt on the empirical plausibility of the prevailing (neoclassical and New Keynesian) models which seem to rely heavily on the lump‐sum tax notion, thus ignoring the substitution effects of distortionary taxation. 相似文献

The significance of learning by doing to input demand of a cost-minimizing rate-of-return-regulated firm is examined. Using a panel data, the results indicate that the firm's cost and input demand decisions are both influenced by learning-by-doing. The firm's cost and the rate-base (capital) input requirements decline as learning-by-doing measured by cumulative production expands. However, LBD may have different effects on the non-rate-base inputs (labor and fuel) considered in this study. While LBD ambiguously reduces fuel usage, it moderately increases labor employment. In addition to changing input intensity, LBD also influences returns to scale and elasticity of substitution. 相似文献

We show that the Hotelling–Lau elasticity of substitution, an extension of the Allen–Uzawa elasticity to allow for optimal
output-quantity (or utility) responses to changes in factor prices, inherits all of the failings of the Allen–Uzawa elasticity
identified by Blackorby and Russell [(1989) Am Econ Rev 79: 882–888]. An analogous extension of the Morishima elasticity of
substitution to allow for output quantity changes preserves the salient properties of the original Hicksian notion of elasticity
of substitution.

土地政策改革时期的城市空间发展:北京的实证分析 总被引:14,自引:0,他引:14
论文探讨北京城市空间发展的特征、并探究空间发展的特征与正在发展壮大的土地市场和土地制度改革之间的关系.利用1993年到2000年上半年北京城市建设区土地使用权出让数据,实证分析显示土地价格及土地开发密度都随着距城市中心区的距离增加呈下降趋势.实证分析还表明地租的曲线的空间变化与土地使用类型相关.这些实证证据支持如下结论:正在形成的土地市场确实影响城市土地开发和空间形态.实证分析还显示地租曲线的斜率和土地-资本替代弹性系数都随着时间的推移而变化.正如城市经济理论所预测,地租曲线斜率的下降是由于北京大量的交通投资降低了交通成本,从而又反过来使城市土地地租空间变化曲线发生旋转.土地-资本替代弹性指数的增加意味着价格影响土地开发密度.这两者的变化都反映出北京的土地市场正走向成熟.应该指出,在土地市场之外(在行政划拨的土地上)进行的大量开发对北京正在形成和发育的土地市场会产生扭曲. 相似文献
