Does knowledge diffusion between university and industry increase innovativeness?

This paper presents an econometric analysis of the impact of collaboration with universities on the innovative output of firms. We also illustrate the differences that emerge from robustness checks, based on different matching estimators and samples. Our findings strongly suggest that university collaboration has a positive influence on the innovative activity of large manufacturing firms. In contrast, there appears to be an insignificant association between university collaboration and the average service firm’s innovation output.     

Science Parks’ tenants versus out-of-Park firms: who innovates more? A duration model

We study the successfulness of Science Parks (SPs) as seedbeds of innovation. We investigate whether SPs enhance the innovative output of their tenants and if tenants outperform comparable outside-SPs firms. We rely on original matching datasets regarding in- and out-SP Finnish firms and their patenting activity over 1970–2002. We estimate and compare the ‘before-versus-after’ hazard rates of patenting of both samples. The results suggest that, given the existence of a common tendency to slow down the pace at which all firms patent during their life cycle, Park tenants exhibit a comparatively better performance. Results are robust to various model specifications and to Wald tests performed over the pooled samples.

倾向度匹配、救助依赖与瞄准机制——基于社会救助制度实施效应的经验分析

为更好地了解社会救助制度实施状况,笔者第一次尝试性地利用实际调查微观住户数据资料,结合倾向度匹配方法分析了目前中国社会救助体系对贫困家庭的瞄准机制、实施效果等问题。分析结果显示,中国社会救助方式在经济和社会体制转型过程中产生了显著性的改变。并且从"救助依赖"产生的视角来看,中国社会救助制度在设定的过程中能在一定程度上规避制度本身产生的"救助依赖"问题。针对这个问题我们分析了受助群体再就业家庭对社会救助制度待遇高低的反应,通过其再就业行为的变化,提出了规避受助家庭成员在再就业市场上产生的负面影响,从而更好地促进社会救助制度实施正面效应。     

Type of education and voter turnout – Evidence from a register-based panel

The relationship between education length and voter turnout has been one of the most studied in the political participation literature in recent decades. However, few studies focus on education type, and most of the existing research on this topic relies on cross-sectional data. In the current study, we utilize a large register-based panel dataset to investigate the effect of education type. We find no effects of education type when investigating overall types of education, but we find substantial effects when examining a specific type of education program with a particularly high civic content.     

The political consequences of transitions out of marriage in Great Britain

This article uses British Household Panel Survey data to estimate the effects of divorce and widowhood on political attitudes and political behavior. In contrast to previous research, which mostly relied on cross-sectional data, a matched propensity score analysis does not find any effects of transitions out of marriage on policy preferences, party identification, or vote choice. The results also show that divorce (but not widowhood) substantially reduces electoral participation. Some preliminary evidence suggests that this effect of divorce on turnout is partially attributable to the increased residential mobility that accompanies divorce.     

择偶中的生肖匹配——基于层叠拓扑模型的实证研究

本文使用2000年人口普查数据验证传统生肖婚配习俗在现代婚姻中的现实影响力。分析发现,人们一般会对生肖匹配的忌比合更在意;各种民间生肖婚配俗语和六害因大五婚歌而广为流传而在民间有较强的影响力。     

如何科学评估公共政策? ——政策评估中的反事实框架及匹配方法的应用

公共决策科学化依赖于科学的公共政策评估。随着国外公共政策评估研究越来越依赖于旨在评估政策因果效应的因果推断方法,国内公共政策学者也开始进行初步尝试,但是如何有效选择和运用因果推断方法开展政策评估研究仍有待系统梳理。本文介绍了公共政策评估方法的反事实框架,精确定义了公共政策的因果效应。在此基础上,本文将匹配方法总结为距离测算与配对两个步骤,并详细阐述了协变量匹配、粗糙完全匹配、马氏距离匹配、倾向值匹配和熵平衡匹配的原理,比较了不同方法的优势与劣势。结合公共政策评估的前沿实证研究,本文介绍了如何具体运用匹配方法进行政策评估研究。本文还探讨了应用匹配方法的注意事项,包括匹配方法的适用性、匹配与回归的关系、匹配方法对样本数量的要求及是否允许放回等。     

Winning & losing in coalition systems. A quasi-experimental study of the effect of coalition formation on satisfaction with democracy

Does government formation affect satisfaction with democracy? Research so far has focused on how winning or losing elections affects satisfaction with democracy, yet, in many coalition systems, who wins and who loses is not determined directly by the elections, but by the coalition formation process. Until now, the effect of government formation on satisfaction with democracy has not been examined. In this paper, we examine this using a quasi-experimental matching design examining eleven elections. We find some evidence that the formation of the coalition slightly but significantly lowers the satisfaction with democracy among those who supported a party that was removed from the governing coalition. This suggests that in coalition systems, looking at electoral winners and losers may be insufficient.
