During the period of 1992 to 1996, the cable television industry in the United States was regulated by the FCC, which took several price cap measures. As a result, the increase in the price cable service substantially slowed. However, the cable demand did not rise as anticipated. Using a model of imperfectly discriminating monopoly, the paper empirically investigates this curious phenomenon of stagnant demand despite lower prices. The paper finds that the FCC's price capping constrained both demand and prices. The demand was constrained since the price cap was designed to cover almost all TV channels carried by cable systems, and subsequently discouraged cable systems from meeting different customer preferences with multi-tier services. 相似文献

Fear has been widely expressed that the modern rice varieties have created large disparities in regional income distribution, as the productivity gap between favorable and unfavorable rice-production environments widened due to differential technology adoption throughout South and Southeast Asia over the last two decades. Technology affects the income of farm population directly through its effects on productivity and factor use, and indirectly through its effect on factor prices. In particular, the ultimate distributional impact of modern varieties will critically depend on the interregional labor-market adjustments through migration in response to regional wage differentials created by the differential technology adoption, since labor is the main resource of the majority of the rural population. We studied favorable and unfavorable rice-growing villages in the Philippines, and found that adoption of modern varieties during the 1970s was positively related to population growth rate. Contrary to popular belief, no association was observed between wage rates and adoption of modern varieties as of 1986. These findings support the hypothesis that the differential adoption of modern rice varieties induced interregional labor migration toward equalization of wage income across different production environments. 相似文献

Effect of modern rice varieties and irrigation on household income distribution in Nepalese villages
Since high-yielding modern rice varieties (MVs) are adopted only in favorable production environments, significant regional productivity differentials have emerged in Nepal. This study explores the distributional consequences of such differential MV adoption based on an intensive survey of favorable and unfavorable villages. We found that MV adoption increased returns to land but decreased family labor earnings from rice production, as it facilitated the substitution of hired for family labor. As a result, the differential MV adoption did not significantly worsen the household income distribution according to the results of the counterfactual Gini decomposition analysis. 相似文献

Although the inland region of China has generally been left behind in economic development compared with the coastal region, the motorcycle industry in Chongqing has recorded remarkable growth due to the meteoric rise of private enterprises over the last decade. Based on panel data of enterprises, we attempt to identify the factors behind the dynamic development of this industry. We conclude that the success of the motorcycle industry in Chongqing is attributable to a combination of positive features from the Wenzhou model in the 1990s, in which industrial development is based on clustering of private enterprises, and the Sunan model in the 1980s, in which industrial development is based on the effective use of human resources recruited from existing state-owned enterprises (SOEs). Learning by collective enterprises from SOEs in Chongqing coupled with the growth of the private enterprise sector fostered cluster-based industrial development.

Comparing dynamic changes in household income and poverty among urban, rural, and estate sectors in Sri Lanka from 1990 to 2006, this study finds that a shift of household income away from farm to nonfarm sources is accompanied by a significant improvement in household income and reduction in poverty, particularly in the rural sector. Major contributing factors are the rise in returns to labor, in general, and educated labor, in particular, due to the development of the nonfarm labor market. Persistently low income among estate households can be explained primarily by the limited availability of nonfarm employment opportunities and the low education levels of working members. 相似文献

Tax portfolio literature has focused on deriving the optimal composition of the tax structure for a particular state. However, tax revenue flow is influenced by both tax structure and economic conditions which are unique for each state. Therefore, the literature has been unable to generalize the characteristics of optimal tax structures. This paper examines the contribution of a state's economic condition, as well as the tax structure, to the growth and variability of tax revenue flow. In addition, the optimal tax portfolio is studied for changes in revenue growth targets and economic conditions. 相似文献

In this study we investigated the nature of disagreement, which is a necessary component of a good discussion. We obtained
27 group discussion scenes by Japanese undergraduates that were evaluated by two ways: impression rating and ranking. As a
result of factor analysis for the impression rating data, five factors were extracted: activeness, multidirection and unification
of discussion, relationships of participants, development and sophistication of discussion, and sincerity of the participants, and each factor scores of each scene was simultaneously calculated. Each scene’s rank score was also calculated by relative
comparisons. A significant positive correlation was found between the mean factor and the rank scores except for Factor 3
(relationships of participants). To consider the reason for the difference relating to Factor 3’s score, we scrutinized the discussion process of four scenes
of the different patterns of the factor and rank scores. From the analysis of conversations, we suggested that this difference
reflected ways of disagreement. By introducing a probative discourse tags for discussion (pDTD), we reasoned that the frequency
of disagreement made Factor 3’s score negative and the absence of the second part of adjacency pairs made the rank score worse.
The explicit speech and actions of blame such as emotional and aggressive expression, and neglect of treatment for the minor
opinion made also the discussion unfair, but we think that these behaviors might erupt from the ground made by the accumulated
implicit behaviors such as the absence of the second part. We finally concluded that the criticism type of disagreement increased the rank scores, and its censure type produced lower results, and the proper ways of disagreement in group discussions were discussed. 相似文献

This paper aims to review the process of mobile phone operators agreeing to introduce mobile number portability (MNP) in Japan. A study group formed by the Ministry of Internal Affairs and Communications estimated the proportion of MNP users and analyzed the user benefits and associated costs to introduce MNP. Owing to the particular market structure and technology available, MNP was expected to yield a larger benefit in the Japanese mobile market than that seen in other countries. Based on the results of the research reviewed with respect to the market situation one year after introducing MNP, the increased competition in the mobile phone market was onfirmed by decreasing call charges and a reduction in the share of the dominant operator. 相似文献

By now new modern rice varieties (MVs) with multiple pest and disease resistance have completely replaced early MVs, such as IR5 and IR8, except in a few areas of Asia. This study attempts to identify the changing impacts of ‘first-generation’ and ‘second-generation’ MVs on productivity in rice farming by estimating the yield function, while correcting selectivity bias arising from the choice of varieties. For this purpose, we used farm-level survey data collected for eleven cropping seasons in Central Luzon in the Philippines from 1966 to 1990. We found that while the yield advantage of first-generation MVs over traditional varieties was limited, the yield-increasing effect of second-generation MVs over first-generation MVs was highly significant. In particular, the adoption of improved MVs significantly contributed to yield growth under the irrigated condition and during the dry season. Thus, we conclude that the Green Revolution would not have been revolutionary without the development and the diffusion of second-generation MVs with multiple pest and disease resistance. 相似文献
