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. 相似文献

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。 相似文献

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. 相似文献

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。 相似文献

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. 相似文献
