In a homogeneous‐good duopoly game with a home and a foreign firm, which compete on prices, it has been shown that the optimal way to assist the domestic industry is by a production subsidy. The argument here is that the subsidy is used to keep potential competitive pressure on the foreign firm. This paper analyzes under which conditions this threat of entry of a subsidized home firm is credible. It is shown that in markets where the firms move before the government, a subsidy is not credible and dominated by a tariff in terms of welfare. 相似文献

In many countries, pharmacies receive high regulated markups and are protected from competition through geographic entry restrictions. We develop an empirical entry model for pharmacies and physicians with two features: entry restrictions and strategic complementarities. We find that the entry restrictions have directly reduced the number of pharmacies by more than 50%, and also indirectly reduced the number of physicians by about 7%. A removal of the entry restrictions, combined with a reduction in the regulated markups, would generate a large shift in rents to consumers, without reducing the availability of pharmacies. The public interest motivation for the current regime therefore has no empirical support. 相似文献

A bstract . Henry George supported labor unions and was proud of his membership in the Printers' Union. But he did not regard them as the final solution of labor exploitation. He championed labor as one of the producing classes. His foray into politics as the candidate of organized labor's third party was characteristic; he had had much involvement in politics earlier. Although he supported labor's immediate demands, he sought mainly to use his candidacy to build a constituency for the single tax. Samuel Gompers , then head of the American Federation of Labor , at first worked for George's election but came to the belief that the unions alone should direct and control their political efforts. This view prevailed, though he and George remained good friends. But it is now a question whether Gompers' policy, at this time, serves labor's best interests. 相似文献

Abstract . The ‘basic needs’ strategy in development planning calls for giving priority to meeting minimum human needs and providing certain essential public services. This investigations studies its relevancy for developing technology and change in low income countries. It advances the case for an operationally-oriented basic needs concept for technology in such countries. It outlines a simplified planning model incorporating such a strategy. Eight equations are developed to yield an illustrative preliminary function showing the basic needs technology interacting with a structure of production, consumption and accumulation. 相似文献

Aggregation effects on price and expenditure elasticities in a quadratic almost ideal demand system 总被引:1,自引:0,他引:1
Abstract. While it is well known that demand elasticities calculated at the macro level will in general differ from those calculated at the micro level because of aggregation effects, there remain the questions of how large the effects are and how they vary with the degree of inequality in the income distribution. We explore these questions with models based on a quadratic version of the Almost Ideal Demand System. We investigate the elasticity differences theoretically and then calibrate the models and generate numerical results, using income data for seven countries with widely different distributions. The aggregation effects are found generally to be rather small, even with highly unequal income distributions. 相似文献
