A Classification of Dutch Manufacturing based on a Model of Innovation

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.

Exploring the Intensive and Extensive Margins of World Trade

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. JEL no. F12, F15     

Does Gravity Matter in a Service Economy?

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. JEL no. F13, F15, L80     

Pure Altruism,Consumer Behavior and Choice Modeling*

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.     

关于中国劳动力工资、产业结构和收入差距的实证研究

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。     

基于建立估价模型的企业并购绩效评价研究

企业并购绩效可借助一些方法加以评价,本文重点研究建立估价模型评价并购绩效。本文首先深入研究建立估价模型评价企业并购绩效的基本原理；在此基础上,通过对具体案例并购绩效实证研究进一步验证文中观点。本文认为建立估价模型、借助于EVA评价企业并购绩效是一种比较理想的方法。     

产业集群驱动的工业化道路——重新解读“温州模式”

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。     

保险业增长预测中数量经济模型的应用研究

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。     

消费结构升级与技术进步

文章将技术进步分解为技术效率与技术创新,并沿着成果转化、自主创新和技术模仿等路径,探讨了消费结构升级对技术进步的影响及条件。文章认为,消费结构升级引导着资源的配置方向;沿着不同的路径,消费结构升级带来了不同形式的技术进步。一方面,消费结构升级可促进科技成果转化,在生产前沿不变的条件下提高技术效率。当发明专利得到更好的保护时,生产者推动成果转化的积极性会提高,这时,可用的科技成果越多,消费结构升级越能推动技术效率提升。另一方面,消费结构升级还能推动企业突破现有的生产前沿,实现技术创新。由于小企业运营更灵活、竞争压力更大,在企业平均规模较小的市场结构中,消费结构升级更能推动技术创新;而政府主导的研发往往缺乏行业需求等信息,可能与消费者的实际需求脱节,因此,政府主导的研发投入越多,消费结构升级越难拉动技术创新。不仅如此,在开放条件下,企业还可以通过模仿去满足消费结构升级带来的新需求,进口越多,模仿的空间越大,这种模仿会提升技术效率,但可能会不利于技术创新。基于1999-2015年的省级面板数据,文章对上述假说进行了检验,结果表明上述论断成立。
