In the literature on monetary economics, there is the ‘inflationary bias’ result which predicts that the rate of inflation will be biased towards a higher level under discretionary monetary policy than under a rule‐based policy regime. It is established that a credible nominal target can eliminate this ‘inflationary bias’. In this paper, we examine the case of nominal GDP targeting, which is a rule‐based monetary regime. Depending on the degree of conservativeness by the central bank, we show in a stylized model the choice of different combination of inflation and real GDP targets can still result in an ‘inflationary bias’, and there also exists the possibility of a ‘dis‐inflationary bias’. 相似文献

Majority of the increase in global energy consumption is from China; hence, studying energy issues, especially in China’s manufacturing industry (CMI), is worthwhile and of much interest in the academic field. Based on the translog cost function, we develop a research framework to study the rebound effect of CMI. Considering the effect of asymmetric energy price, we augment the energy-cost function with asymmetric influence constraint of energy price. Again, we add time series data of CMI’s capital, labor, energy, and mid-input to the model to calculate the direct rebound effect of CMI. We find that the rebound effect of CMI is 44.2%, and CMI still has large energy-conservation potentials. Based on the results of this study, some policy recommendations are provided. 相似文献

随着我国社会主义市场经济和职业教育的迅速发展,社会及企业要求学校毕业生要有一定的理论知识又要有很强的实际操作能力。新的人才需求要求有新的教学模式——"专业基础理论与技能实践一体化"教学模式,要成功地实施一体化教学模式,建设一支既能胜任理论教学又能指导实习操作的"双师型"教师队伍是实施一体化教学的关键。本文就汽车类院校一体化教师培养模式进行探索。 相似文献

Using new estimates of ad valorem equivalent of nontariff measures (NTMs) over time, this paper examines NTMs and tariffs’ relationship for a sample of 70 economies for 4,949 products at the 6‐digit harmonized system level over the period 2003–2015. A panel data methodology models the lagged adjustment of NTMs to tariffs, consistent with a causal relationship. Trade policy substitution is found when the models are estimated in both levels and changes; with this holding for both OECD and non‐OECD countries, but not for the agriculture sector in OECD countries. Overall, there is a fairly complete substitution between policy instruments in absolute terms. 相似文献

In this paper, we propose a goal-based investment model that is suitable for personalized wealth management. The model only requires a few intuitive inputs such as size of wealth, investment amount, and consumption goals from individual investors. In particular, a priority level can be assigned to each consumption goal and the model provides a holistic solution based on a sequential approach starting with the highest priority. This allows strict prioritization by maximizing the probability of achieving higher priority goals that are not affected by goals with lower priorities. Furthermore, the proposed model is formulated as a linear program that efficiently finds the optimal financial plan. With its simplicity, flexibility, and computational efficiency, the proposed goal-based investment model provides a new framework for automated investment management services. 相似文献

基于信任理论,从不同角色视角探究各信任要素对分享经济行为意图的影响。通过构建分享经济信任机制概念模型以及实证检验发现:从需求方视角来看,对个体(供给方)3个维度(能力、正直和善意)的信任、对平台善意的信任以及对产品能力的信任对需求意图产生积极地影响。从供给方视角来看,对个体(需求方)能力的信任和对平台3个维度(能力、正直和善意)的信任对供给意图有正向的影响。需求方更关注人与人之间的信任,而供给方则更看重对平台的信任。通过进一步比较还发现,需求方对平台和个体(供给方)的信任聚焦于善意信任,但供给方则是侧重于对平台和个体(需求方)能力的信任。 相似文献
