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

The Gravity Equation in International Trade in Services 总被引:4,自引:0,他引:4
The main purpose of this paper is to assess the impact of various factors on bilateral services trade, relative to that on
bilateral goods trade. To accomplish this purpose, using the standard gravity model, we ran regressions on bilateral services
trade and goods trade between 10 OECD member countries and other economies (including OECD member and nonmember countries)
for the years 1999 and 2000. One main and interesting result is that services trade is better predicted by gravity equations
than goods trade. Another interesting result is that there is a complementary relationship between goods exports and services
imports.

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.

One of the primary motivations offered by the Bank of Japan (BOJ) for its quantitative easing program—whereby it maintained a current account balance target in excess of required reserves, effectively pegging short-term interest rates at zero—was to maintain credit extension by the troubled Japanese financial sector. We conduct an event study concerning the anticipated impact of quantitative easing on the Japanese banking sector by examining the impact of the introduction and expansion of the policy on Japanese bank equity values. We find that excess returns of Japanese banks were greater when increases in the BOJ current account balance target were accompanied by “non-standard” expansionary policies, such as raising the ceiling on BOJ purchases of long-term Japanese government bonds. We also provide cross-sectional evidence that suggests that the market perceived that the quantitative easing program would disproportionately benefit financially weaker Japanese banks. J.

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

The aim of this paper is to help readers understand the significance of the Gini coefficient. We have two major formulae for the Gini coefficient. One of the formulae bases on the idea of aggregation of the microscopic differences between individuals' incomes or wealth. The idea that underlies the other formula is macroscopic presentation of distribution or concentration of income or wealth. We will show an unabridged proof of the equivalence between these formulae to examine how the two conceptions of the measurement of inequality are linked to each other. 相似文献
