This paper suggests a modification of the method of scoring in the general multivariate qualitative response model to attain simpler computation when there are many observations per cell. The paper shows that the proposed estimator is asymptotically efficient even in the cases when the generalized Berkson's estimator (see Amemiya, Journal of the American Statistical Association, June 1976) is not. 相似文献

This article investigates the impact of technical intervention on the adoption of a set of improved rice production technologies, as well as on productivity and profit for smallholders in rainfed lowland areas in Northern Ghana. The key finding is that productivity and profit are significantly enhanced when modern varieties (MVs) and chemical fertilizer are adopted, coupled with water control techniques. This is essentially the transfer of the Asian Green Revolution to sub‐Saharan Africa. Such transfer, however, is not truly successful unless information about the use of MVs and fertilizer is directly disseminated by extension activities. 相似文献

Shared Renewable Resources: Gains from Trade and Trade Policy 总被引:1,自引:0,他引:1
This paper examines the effects of international trade and trade policy in a two‐country, two‐good model with an open‐access renewable resource that is internationally shared. We show that both countries may still benefit from trade when they specialize in the production of their comparative advantage good, although the shared resource is reduced by trade. In addition, we demonstrate that the steady state utility of a resource‐good importing country may be reduced by trade, even if it specializes in the production of a non‐resource good. Import tariffs and export taxes on a resource good may increase or decrease the shared stock level depending on the production patterns in a trading steady state. The trade policy is likely to be Pareto‐improving when the shared stock rises, while both countries may be made worse off by the trade policy when the shared stock falls. 相似文献

In this paper, we consider third-degree price discrimination in two markets in the presence of asymmetric consumption externalities;
we establish that under plausible conditions, a firm reduces its price in the market with low price elasticity of demand.
The firm can increase its profits by reducing the price for these consumers and enlarging the demand for other consumers,
provided that positive consumption externalities exist. Moreover, we show that third-degree price discrimination enhances
not only the firm’s profit but also total consumer surplus.

We construct a two-period model in which a consumer recognizes the existence of goods after advertised by firms, and total sales of the first period affect the utility of each consumer’s purchase in the second period, indicating a consumption externality. Some consumers see advertisements in the first period and remember the product, whereas some forget the product in the second period. We show that the advertising volume changes given the differences in the forgetting rate. In particular, we apply our method to the data on Japan’s electronic books obtained through a conjoint analysis survey to clarify that a better strategy is to sell a product to a small number of people at a low price or to lower the price to a certain level during the early period, and then to sell the product to a specific consumer segment at a higher price after reflecting the externality. 相似文献

Using two household surveys, this paper investigates whether the saving rates of richer households are higher than those of poorer households in Japan. We construct a number of proxies for lifetime wealth, including those original to this study, and find marginally positive correlations between saving rates and lifetime wealth for working age households. We further find that the relationship between saving rates and lifetime wealth differs depending on the life stage of individual households. Older households with higher lifetime wealth appear to be dissaving to some extent, which is more or less consistent with the lifecycle model of consumption. 相似文献
