The Macro Pedagogy Debate: Teaching DSGE to Undergraduates Symposium

Dynamic stochastic general equilibrium (DSGE) models have become the workhorse of modern macroeconomics and the standard way to communicate ideas among applied macroeconomists. Undergraduate students, however, often remain unaware of their existence. The lack of specialized knowledge can hurt them if they decide to attend graduate school. Indeed, many first-year PhD students discover that the material they are currently learning differs significantly from what they mastered in college. But this can change. In this article, the author describes how to teach a full-fledged macroeconomics course where DSGE models take center stage. He discusses how to arrange such a course within a one-semester time frame, details the main components of instruction, and finishes with some thoughts based on his teaching experience at Macalester College.     

中美贸易关系新形势下中国先进制造业升级路径研究

先进制造业是一国工业实力和竞争力的直接体现。目前,在中国先进制造业中,装备制造业竞争力明显提升、高技术制造业发展迅速、先进制造业出现集群式发展,但仍然存在创新能力较低、核心技术和零部件研发能力不强、先进制造业企业竞争力不强、缺乏有利的先进制造业发展环境等问题。应采取给予先进制造业发展更大的支持力度、坚持技术引进与自主创新融合、强化先进制造业的区域合作、引导企业提高自主创新能力等措施,推动中国先进制造业持续健康发展。

Confirming the timing of phase-based costing in oncology studies: a case example in advanced melanoma

Aims: The utilization of healthcare services and costs among patients with cancer is often estimated by the phase of care: initial, interim, or terminal. Although their durations are often set arbitrarily, we sought to establish data-driven phases of care using joinpoint regression in an advanced melanoma population as a case example.

Methods: A retrospective claims database study was conducted to assess the costs of advanced melanoma from distant metastasis diagnosis to death during January 2010–September 2014. Joinpoint regression analysis was applied to identify the best-fitting points, where statistically significant changes in the trend of average monthly costs occurred. To identify the initial phase, average monthly costs were modeled from metastasis diagnosis to death; and were modeled backward from death to metastasis diagnosis for the terminal phase. Points of monthly cost trend inflection denoted ending and starting points. The months between represented the interim phase.

Results: A total of 1,671 patients with advanced melanoma who died met the eligibility criteria. Initial phase was identified as the 5-month period starting with diagnosis of metastasis, after which there was a sharp, significant decline in monthly cost trend (monthly percent change [MPC]?=?–13.0%; 95% CI?=?–16.9% to –8.8%). Terminal phase was defined as the 5-month period before death (MPC?=?–14.0%; 95% CI?=?–17.6% to –10.2%).

Limitations: The claims-based algorithm may under-estimate patients due to misclassifications, and may over-estimate terminal phase costs because hospital and emergency visits were used as a death proxy. Also, recently approved therapies were not included, which may under-estimate advanced melanoma costs.

Conclusions: In this advanced melanoma population, optimal duration of the initial and terminal phases of care was 5 months immediately after diagnosis of metastasis and before death, respectively. Joinpoint regression can be used to provide data-supported phase of cancer care durations, but should be combined with clinical judgement.

Interrelationship between crude oil and the stock markets of major demanders and suppliers in emerging and developed markets

This paper investigates the time-varying relationship between the stock markets of advanced and emerging oil-exporting and oil-importing countries and the international crude oil price indices. The results reveal that the time-varying among the oil-exporting and oil-importing countries responds similarly to aggregate supply- and demand-side effects. Oil-exporting countries have a slightly higher integration with the oil markets, while oil supply shocks have a slightly higher impact on emerging oil-exporting countries. The oil markets exhibit a lower time-varying relationship with the Asia-Pacific oil-importing markets, which indicates those markets may be attractive to investors during periods of turbulence in the oil market.     

房产税促进地区产业结构优化的路径与异质性表现——产业转移和企业创新视角的沪渝比较

房地产市场过度繁荣带来的房价过快上涨会影响要素流动和企业行为，进而加剧资源错配，不利于地区产业结构优化。征收房产税可以有效抑制房价过快上涨，通过地区相对房价的下降减轻资源错配程度，并从影响产业转移和推动企业创新两条路径促进地区产业结构优化。运用合成控制法对上海和重庆房产税改革试点的政策效应进行评估，结果表明：重庆的房产税政策有效抑制了房价过快上涨，促进了先进产业的转入和创新水平的提高，进而显著提高了地区产业结构合理化和高级化水平，地区产业结构优化效应明显；上海的房产税政策对房价上涨的抑制作用不明显，高房价阻碍了高技能人才的流入，导致其产业高级化水平的提高更多依赖于低端服务业的发展，不利于地区产业结构合理化，总体上并未能有效促进地区产业结构优化。上海与重庆房产税政策效应的差异不仅源于其政策力度的不同，还由于两地经济发展水平和产业结构的不同。房产税政策必须有效抑制房价上涨，并应结合本地经济发展实际因地制宜，才能更好地促进地区产业结构优化。     

我国先进装备制造业全要素生产率及影响因素分析——基于产业组织视角

本文基于先进装备制造业上市公司2006～2015年的数据，使用DEA-Malmquist方法计算了我国先进装备制造业的全要素生产率，结果表明，考察期内我国先进装备制造业的全要素生产率在震荡中有所提升，东部地区先进装备制造业的全要素生产率提升幅度大于西部。以此为基础，基于产业组织的角度分析了先进装备制造业全要素生产率的影响因素，研究发现，人力资本水平、R&D经费投入、宏观经济形势、社会固定资产投资情况、对外贸易依存度以及科技劳动力对全要素生产率产生正向显著影响。最后针对本文结论提出相关建议。     

Advanced information technology: transforming service innovation and design

This research explores the role of advanced information technologies at the ‘fuzzy’ front-end of service innovation and design. Service researchers have been exploring the application of technology to services for a while, however there has been little attention paid to the use of technology at the front-end of service innovation and design. Research suggests that advanced information technologies should be useful in research and development for services; but how this may occur has not been explored. Bringing together design thinking and the technology–organization–environment framework for technology adoption this research develops propositions for research to expose how technology can advance and transform service innovation and design. Theoretical and practical research questions are offered to guide inquiry in this emerging research space.
