项目摘要

This year is the second and the last year of our research project on theoretical investigations on growth models which involve endogenous technological progress. This year, we have been mostly concerned with various applications of growth models with endogenous technocal progress. In the paper enttitled, "Threshold Externalities...." (published in Economics Letters), we introduce threshold externalities of technological spillovers in the standard growth model and show that growth process will be significantly different from that of the model without threshold extenalities : cyclical growth and indeterminacy of growth paths may easily emerge in ouf framework. In the second paper, "Monetary Policy, ....." (to be published in Economica), we consider the effects of money supply policy on long-run growth rate and patters of growth of the economy by use of an endogenous technical progress due to externalities. In addition, we wrote an accompanid paper (which is now submitted to a specialized journal) that deals with welfare effects of monetary policy in an endogenously grouwing monetary economy.We also analyze models of endogenous growth that explicitly formulate R&D behavior of firms. Here, our central concern is to examine the effects of international technological spillovers in the context of two-country model of economic growth. Using a model of 'horizontal product expansion', we study how international technological spillovers affect the long-run growth rate of the world economy as well as the long-run position of current account of each country. Research on this issue has been summarized as an unpublished paper that is now under revision for submission to an appropriate journal.

今年是我们对涉及内生技术进步的增长模型进行理论研究的研究项目的第二年，也是最后一年。今年，我们最关注的是内生技术进步的增长模型的各种应用。在题为“阈值外部性......”（发表于《经济学快报》）的论文中，我们在标准增长模型中引入了技术溢出的阈值外部性，并表明增长过程将与没有阈值外部性的模型显着不同：周期性增长和增长路径的不确定性很容易出现在ouf框架中。在第二篇论文“货币政策......”（将在《经济》杂志上发表）中，我们利用内生技术分析来考虑货币供应政策对经济长期增长率和增长模式的影响。由于外部因素而取得进展。此外，我们还撰写了一篇附带论文（现已提交给一家专业期刊），讨论在内生增长的货币经济中货币政策的福利效应。我们还分析了明确制定企业研发行为的内生增长模型。在这里，我们的中心关注点是在两国经济增长模式的背景下研究国际技术溢出的影响。我们运用“水平产品扩张”模型，研究国际技术溢出如何影响世界经济的长期增长率以及各国经常账户的长期状况。关于这个问题的研究已被总结为一篇未发表的论文，目前正在修改以提交给适当的期刊。
