Summary The paper studies the degree of homogeneity of innovative behavior in order to determine empirically an industry classification
of Dutch manufacturing that can be used for policy purposes. Defining homogeneity in terms of an economic model distinguishes
our classification from existing taxonomies such as those of the OECD, Pavitt and the various classifications based on a principal
components analysis. We use a two-limit tobit model with sample selection, which explains the decisions by business enterprises
to innovate and the impact these decisions have on the share of innovative sales. The model is estimated for eleven industries
based on the Dutch Standard Industrial Classification (SBI 1993). A likelihood ratio (LR) test is then performed to test for
equality of the parameters across industries. We find that Dutch manufacturing consists of three groups of industries in terms
of innovative behavior, a high-tech group, a low-tech group and the industry of wood. The same pattern shows up in the three
Dutch Community Innovation Surveys.
The empirical part of this study has been carried out at the Centre for Research of Economic Microdata at Statistics Netherlands.
The authors wish to thank Statistics Netherlands, and in particular Bert Diederen, for helping us in accessing and using the
Micronoom data set. The views expressed in this paper are solely those of the authors. The authors also wish to thank Fran?ois
Laisney, Patrick Waelbroek and participants at presentations in Maastricht, Strasbourg, Leuven and Lille for their helpful

Exploring the Intensive and Extensive Margins of World Trade 总被引:1,自引:0,他引:1
World trade evolves at two margins. Where a bilateral trading relationship already exists it may increase through time (intensive
margin). But trade may also increase if a trading bilateral relationship is newly established between countries that have
not traded with each other in the past (extensive margin). We provide an empirical dissection of post–World War II growth
in manufacturing world trade along these two margins. We propose a “corner-solutions version” of the gravity model to explain
movements on both margins. A Tobit estimation of this model resolves the so-called “distance puzzle”. It also finds more convincing
evidence than recent literature that WTO-membership enhances trade.

This paper estimates gravity equations for bilateral services trade in a sample of 28 countries. It finds that the standard
gravity variables of economic size and geographic proximity are significant factors in services trade. It also reveals positive
effects of linguistic ties on services trade. There is evidence of a positive link between regional trade arrangements and
services trade. Much of that effect appears to reflect the impact of bilateral goods trade on services trade. This implies
that efforts to enhance goods trade—bilateral or multilateral—should lead to more services trade as well.

An important assumption underlying non‐market valuation is that it is not the environment but the human preference that is valued. This paper attempts to test whether individual consumer behavior is influenced by a purely altruistic motive, examining the attitude of hikers towards the hypothetical removal of the Muju ski resort from the Mount Togyu National Park in South Korea. Data were collected from samples of hikers and skiers who visited the national park. The respondents were forced to consider trade‐offs between the recovery of the lost environmental assets in the Muju ski resort area, skiers’ additional travel time, and willingness‐to‐pay amounts for the hypothetical environmental improvement. It was found that hikers did not take into account skiers’ disutility represented by additional travel time. 相似文献

本文基于GTAP模型,模拟了中国劳动力工资水平的外生上涨对社会贫富差距以及劳动密集型产业转移的影响。通过研究发现:非熟练劳动力密集型产业的普通工人工资的外生上涨无助于解决中国的收入差距问题,反而非熟练劳动力密集型产业在国际间的转移,会使中国有了更高的失业率,甚至有可能使收入差距扩大。 相似文献

通过对“温州模式”的研究,发现温州遵循“开放-发现-创业-扩散-升级”这样一条产业集群驱动的工业化道路,其发生机理是由于开放,增加了同外部市场接触的机会,发现了市场信息并完成了初始资本的积累,当企业家能人出现、开始在某地创业时,本地工业化进程便随之启动。 相似文献

保险业增长预测中数量经济模型的应用研究 总被引:1,自引:0,他引:1
科学合理地预测保险业的发展状况,对于明确保险业未来的总体发展目标和战略重点。促进保险业持续健康发展,具有十分重大的意义。本文以内蒙古自治区保险业为例,通过对2006年-2010年内蒙古自治区保费收入的增长预测,提出了综合运用多元线性回归模型和霍尔特指数平滑法进行保险增长预测的预测方法。与传统预测方法相比,它能更好地保证保险增长预测的精确度。 相似文献
