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 Research on this issue has been summarized as an unpublished paper that is now under revision for submission to an appropriate journal.

今年是我们关于包含内生技术进步的增长模型的理论研究的第二年，也是最后一年。今年，我们主要关注内生技术进步增长模型的各种应用。在题为《门槛外部性》的论文中，“（发表于Economics Letters），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著不同：在OUF框架中，周期性增长和增长路径的不确定性可能容易出现。在第二篇论文中，“货币政策，......“（将发表在Economica），我们考虑了货币供应政策对长期增长率的影响，并通过使用由于外部性而产生的内生技术进步来研究经济增长模式。此外，我们还撰写了一篇论文（目前已提交给专业期刊），探讨了内生增长货币经济中货币政策的福利效应。我们还分析了明确表述企业研发行为的内生增长模型。在此，我们主要关注的是在两国经济增长模型的背景下研究国际技术溢出的影响。本文利用一个“横向产品扩张”模型，研究了国际技术溢出对世界经济长期增长率和各国经常账户长期地位的影响。关于这一问题的研究已被归纳为一份未发表的论文，目前正在修订中，以便提交给适当的期刊。
