In the process of coding open-ended questions, the evaluation of interjudge reliability is a critical issue. In this paper, using real data, the behavior of three coefficients of reliability among coders, Cohen’s K, Krippendorff’s α and Perreault and Leigh’s I r are patterned, in terms of the number of judges involved and the categories of answer defined. The outcome underlines the importance of both variables in the valuations of interjudge reliability, as well as the higher adequacy of Perreault and Leigh’s I r and Krippendorff’s α for marketing and opinion research.  相似文献

We study the factors influencing the percentage of organic and fair trade certified coffee sold through a cooperative by growers of five cooperatives in Mexico. The percentage of coffee sold through the cooperative was used as a proxy of growers’ engagement with a cooperative. Using factor analysis and a fractional probit regression, we evaluated the proposition that the level of engagement can be explained by transaction cost economics, social norms and connections, and farmer and farm business characteristics. We found that farm size, uncertainty regarding cooperative time of payment to the members and cooperative commitment on price to be paid negatively influence the level of engagement. In contrast, asset specificity, relational commitment, and price have a positive impact on engagement. Our results may help cooperatives and policy makers to build strategies aiming to increase this level of engagement. This is relevant because lower grower engagement has been found to be positively correlated with weak performing cooperatives.  相似文献

This paper evaluates the impact of farmer field schools, an intensive participatory training program emphasizing integrated pest management. The evaluation focuses on whether program participation has improved yields and reduced pesticide use among graduates and their neighbors who may have gained knowledge from graduates through informal communications. The study utilizes panel data covering 1991–99 in Indonesia. The analysis, employing a modified "difference-in-differences" model, indicates that the program did not have significant impacts on the performance of graduates and their neighbors. Several plausible explanations for this outcome are discussed, and recommendations for improvements are suggested.  相似文献

This study examines the effect of the sale and leaseback of corporate real estate on the stock prices of the selling firms. We ask whether the Tax Reform Act of 1986 (TRA 1986) had a negative impact on the market valuation effects of corporate sale and leasebacks. The results of the comparative statics analysis predict that the net present value of the lessee should be negatively related to the tax depreciation recovery life for the lessor and to the marginal ordinary income tax rate of the marginal holder of commercial mortgage debt. However, it should be positively related to the marginal tax rate of the equityholder of the corporate lessee. Changes in the marginal ordinary income tax rates of the lessor and the corporate lessee have an ambiguous effect on the equity value of the corporate lessee. Nevertheless, results of simulation analyses suggest that the relationship between the net present value of the lessee and each of the tax rates of the lessor and corporate lessee is negative. The empirical evidence suggests that subsequent to TRA 1986, the lessee's benefits associated with sale and leaseback transactions have decreased.  相似文献

We show that the single-index dynamic factor model developed by Aruoba and Diebold (Am Econ Rev, 100:20–24, 2010) to construct an index of the US business cycle conditions is also very useful to forecast US GDP growth in real time. In addition, we adapt the model to include survey data and financial indicators. We find that our extension is unequivocally the preferred alternative to compute backcasts. In nowcasting and forecasting, our model is able to forecast growth as well as AD and better than several baseline alternatives. Finally, we show that our extension could also be used to infer the US business cycles very precisely.  相似文献

金钱能买来幸福吗?没人回答能,包括那些改革开放中出现的中国暴发户。可以肯定的是,中国确实在很多方面值得夸耀:现在已经是世界第二大经济体,仅次于美国,人均收入从1980年的不足200美元增长到2010年的3700美元,约3亿农民摆脱了绝对贫困。公民的预期寿命延长了十年。  相似文献

We study a two‐period general equilibrium model with incomplete asset markets and default. We make collateral endogenous by allowing each seller of assets to fix the level of collateral. Sellers are required to provide collateral whose first‐period value, per unit of asset, exceeds the asset price by an arbitrarily small amount. Moreover, borrowers are also required to be fully covered by the purchase, in the first period, of state‐by‐state default insurance. These insurance contracts are offered by lenders. The insurance cost or revenue is a linear charge and plays the role of a spread penalizing borrowers who will incur in default and benefiting lenders who will suffer default. Under these assumptions, equilibrium always exists.  相似文献

In this article Jaime Caruana, Governor of the Bank of Spain and Chairman of the Basel Committee on Banking Supervision, first discusses the current status of the Basel II Accord. Next, he offers his perspective on macroeconomic issues related to the capital framework, focusing especially on pro‐cyclicality. Finally, he discusses three important Basel II implementation issues, namely calibration, validation, and cross‐border supervision.  相似文献

All preferential trading agreements (PTAs) short of a customs union use rules of origin (ROO) to prevent trade deflection. ROO raise production costs and create administrative costs. This paper argues that in the case of the recent wave of North–South PTAs, the presence of ROO virtually limits the market access that these PTAs confer to the Southern partners. In the case of NAFTA, we find average compliance costs around 6% in ad valorem equivalent, undoing the tariff preference (4% on average) for a large number of tariff lines. Administrative costs amount to 47% of the preference margin. These findings are coherent with the view that North–South PTAs could well be viewed like a principal–agent problem in which the Southern partners are just about left on their participation constraint.  相似文献
