When Does an Inflation Target Yield the Second Best?

It is shown that an inflation target does not establish the second best if the central bank is independent and the government collects seigniorage revenues. To eliminate excessive inflation and ensure that stabilization is efficient, society should combine an optimal inflation target with a central bank that attaches less weight to inflation stabilization than the public does.

节能灯照明系统谐波电流问题研究

随着现代电力电子和建筑智能化的迅速发展和普及,电网谐波污染的问题越来越严重。由于谐波危害很大,而且谐波源分布广泛,因此对不同谐波源产生的谐波电流应逐个分析。本文针对商业建筑中大量使用节能灯作为照明灯具的情况,结合工程实际,对25W以下的具有代表性的节能灯进行实验数据采集和分析,并得到重要结论。     

基于Multisim的555定时器与运放构成的矩形波发生器比较分析

为了详细分析目前比较常用的555定时器和运放构成的矩形波发生器,填补其他文章仅单单分析一种电路的空白,利用Multisim强大的仿真分析功能,结合理论计算,对这两种方波发生器进行输出电压特性、占空比调节、输出频率、电源电压范围等方面的比较分析,希望给制作矩形波发生器的读者提供一定的参考价值。     

产品市场竞争与资本结构的战略决策

“有限负债效应”理论指出,企业提高财务杠杆导致了产出的增加,但很多实证研究却难以支持这一结论。本文分析了在上游企业外部规模效应较强的情况下,企业债务融资战略效应为负的理由,证明了不存在外部规模效应是债务融资战略的重要条件。企业的融资行为深受财务危机的影响,其中企业规模、产业集中度、产品专用性、R&D支出和行业前景是决定财务危机成本大小的关键变量,因此,以财务危机成本为依据进行决策,企业会自我限制债务水平。由此,企业资本结构的决策应从产品市场竞争状况去考虑,这对我国企业融资决策有重要意义。     

Exit from the high street: an exploratory study of sustainable fashion consumption pioneers

In today's fashion system, dominated by business models predicated on continual consumption and globalized production systems that have major environmental and social impacts, the consumption of ‘sustainable fashion’ takes on an almost paradoxical quality. This paper explores this paradox by focusing on a previously under‐researched group of consumers – ‘sustainable fashion consumption pioneers’ who actively engage and shape their own discourse around the notion of sustainable fashion consumption. These pioneers actively create and communicate strategies for sustainable fashion behaviour that can overcome the nebulous and somewhat paradoxical reality that sustainable development in the fashion industry presents. Specifically, we use passive netnography and semi‐structured interviews to illuminate the role of motivational and contextual factors that help shape these consumers' definitions of sustainable fashion including such key behaviours as purchasing fewer garments of higher quality, exiting the retail market, purchasing only second‐hand fashion goods and sewing or upgrading their own clothing. Central to much of these behaviours is the notion that personal style, rather than fashion, can bridge the potential disconnect between sustainability and fashion while also facilitating a sense of well‐being not found in traditional fashion consumption. As such, our research suggests that for these consumers sustainability is as much about reducing measurable environmental or social impacts as it is about incorporating broader concepts through which to achieve goals beyond the pro‐environmental or ethical.
