Using State Child Labor Laws to Identify the Causal Effect of Youth Employment on Deviant Behavior and Academic Achievement

On the basis of prior research findings that employed youth, and especially intensively employed youth, have higher rates of delinquent behavior and lower academic achievement, scholars have called for limits on the maximum number of hours per week that teenagers are allowed to work. We use the National Longitudinal Survey of Youth 1997 to assess the claim that employment and work hours are causally related to adolescent problem behavior. We utilize a change model with age-graded child labor laws governing the number of hours per week allowed during the school year as instrumental variables. We find that these work laws lead to additional number of hours worked by youth, which then lead to increased high school dropout but decreased delinquency. Although counterintuitive, this result is consistent with existing evidence about the effect of employment on crime for adults and the impact of dropout on youth crime.

Assessing the (eco)macroeconomic performance index of India: A data envelopment analysis approach

The prime objective of this article is to construct a robust macroeconomic performance (MEP) index of the Indian economy using the data envelopment analysis (DEA) approach. Seven major macro indicators, namely, economic growth, employment rate, terms of trade, inflation rate, fiscal deficit, pollution, and climate change are used to compute MEP and Eco‐MEP indices of the Indian economy from 1980–1981 to 2018–2019. Overall, both the MEP and Eco‐MEP index scores have quite similar best performing years worst performing years, and have also captured the major events that affected adversely the Indian economy during the past decades. The trend in the overall performance of the Indian economy was better in the 1980s and the 1990s but has deteriorated since 2000. The autoregressive distributed lag bounds testing approaches to cointegration methods are used to test the robustness/utility of these indices. The estimated results show that MEP and Eco‐MEP have a positive impact on private investment, foreign investment inflows, foreign direct investment, and a negative effect on the current account deficit. Hence, the suggested composite MEP index is stable, robust and truly captures the economic performance of India. The constructed MEP composite index may be used by foreign investors, rating agencies, private investors, and policymakers for their planning and decision‐making processes.     

计量经济研究实践中的数据运用误差

计量经济学方法已被广泛地应用于经济研究的各个领域,理论、方法、数据是计量经济研究的三大基本要素。综观国内大量的计量经济研究成果,我们发现不尽严密和科学之处并不少见。本文从数据运用角度,列举了计量经济研究实践中的三类偏误现象,以呼吁人们关注计量经济学研究的客观性     

Implications of EU Enlargement on the EU Greenhouse Gas 'Bubble' and Internal Burden Sharing

Currently, the EU-15 forms the only 'bubble' under the Kyoto Protocol and has negotiated an internal burden sharing. A strategic EU climate policy should include accession countries. Thus, even in the case of early ratification of the Kyoto Protocol by 2002, it would be sensible to form a bubble with all countries that are certain to be EU members during the commitment period 2008–2012. Of course due to Art. 4.4 of the Protocol the EU-15 has to stick to its own bubble. However, nothing prevents it from forming an implicit bubble including all first wave countries by inducing them to form a bubble on their own and transfer the surplus to the EU-15. Similarly, second wave countries should form a bubble of their own to co-ordinate JI and permit transfers to the EU. This would reduce the gap between business-as-usual and the target by about 50%. If ratification is delayed to a point where it is clear which second wave countries will be members by 2008, the bubble should be extended by those countries. When in 2005 target negotiations start for the second commitment period, the EU should negotiate a bubble consisting of all states being certain to be members by 2013.     

Testing the Reciprocal Effects of Campaign Participation

Questions persist regarding the robustness of cross-sectional estimates of effects of variables that are themselves endogenous to the participation process. On one hand, the consequences of working on a campaign have interesting implications for democratic society. Less benign, however, is the possibility that failure to control for reciprocal processes leads to biased estimates of the causes of campaign participation. I use a panel of Democratic and Republican contributors interviewed following each of the past three presidential elections (1996, 2000, and 2004) to explore the relationships between campaign participation and three variables typically parameterized as predictors of participation: receiving a contact, ideological extremism, and strength of party identification. The effect of strength of party identification on campaign participation proves robust; however, I find that nearly all of the associations between contacts and participation and ideological extremism and participation appear to extend from, not into, participation and past participation.

Does Workplace Experience Enhance Political Participation? A Critical Test of a Venerable Hypothesis

Several schools of thought claim that citizens can develop their democratic skills at the workplace. Here I focus on the hypothesis put forward by Carole Pateman and by Sidney Verba and colleagues that state that by practicing civic skills and democratic decision-making at the workplace, citizens become more active in politics. I test the hypothesis with a nationally representative panel survey of the Swedish population. My findings contradict previous empirical research as no impact on political participation was discovered. I argue that the effects may have been overestimated in prior studies because the tests were based on cross-sectional data: insufficient care was taken with a number of significant methodological problems. The study points to the importance of using panel models when investigating the causes of political participation.

数据要素对制造业高质量发展的影响——来自制造业上市公司微观视角的经验证据

随着数字经济与实体经济的不断融合发展,数据已经成为经济发展进程中的关键生产要素。基于手工整理的2011—2020年我国A股制造业上市公司年报数据的研究表明：制造业高质量发展是企业研发创新、生产制造、市场匹配三个环节整体联动实现更高效率发展的一种高级状态。数据要素能够显著促进我国制造业高质量发展,且主要是通过关键性技术突破与知识创新的研发创新效应、生产流程优化与协同的生产协同效应产生影响,但市场匹配效应尚未完全显现;数据要素对我国制造业高质量发展的推动作用在非国有企业、高技术密集度行业与东部地区更加显著。研究结论为数字经济时代下我国如何激活数据要素潜能、推进传统产业转型升级提供了政策启示。     

健康医疗大数据的积极利用主义

健康医疗大数据是国家重要的基础性战略资源。为促进我国健康医疗大数据产业发展，应该明确健康医疗大数据积极利用主义规制模式，解决积极利用与知情同意原则之间的冲突。我国立法应鼓励健康医疗大数据的积极利用，通过知情同意原则的灵活运用及替代性或补充性保护机制的引入，解决健康医疗数据利用和保护之间的冲突，按照数据类型区分原则，对健康医疗大数据进行系统、适当的分类，明确原则性规定和例外情形。
