Medium-Term Money Neutrality and the Effective Lower Bound

Conventional wisdom suggests that medium-term money neutrality imposes strong limitations on the effects of monetary policy. The point of this paper is that models with medium- and long-term money neutrality are prone to generate nonexistence of equilibria at the effective lower bound (ELB) on interest rates. Nonexistence is suggestive of sharp output contractions—so-called contractionary black holes—at the ELB. Paradoxically, the case for expansionary monetary policy at the ELB is even stronger in models that feature near money neutrality. The results highlight the benefits of a monetary policy regime in which the central bank temporarily overshoots its inflation target once confronted by the ELB.     

Impact of Digital Economy on Female Employment: Evidence from Turkey

This paper investigates impact of e-economic activities on female employment rates in Turkey over 1994–2016. The analysis unveils three major findings. First, 80.74% of variations in female employment are accounted by e-commerce and control variables. Second, Autoregressive Distributed Lag analysis documents that these series (female employment, e-commerce and control variables) are cointegrated, thus, a unit increase in per credit card e-commerce transactions leads the female employment rate to grow by 0.13?units in long-run at 1% significance level, whereas a percentage increase in internet penetration rate in Turkey augments the rates by 0.33%. Third, error-correction model analysis refers that the system quickly corrects its previous period disequilibrium converging at a speed of 75.43%, and also documents that the lags of per credit card e-commerce jointly have short-run impact on female employment rates. Thus, the study concludes that developing e-commerce incentivizing policies might help to empower women in Turkey significantly.     

迈向“无废管理”:内涵、挑战及对策

建设“无废城市”的关键在于实现城市的“无废管理”。国外已有经验表明,作为一种整体性治理方案,无废管理并不寻求模式的统一,而是体现出很强的灵活性和实践导向性。在梳理国外无废管理缘起与进展基础上,分析、总结了无废管理的内涵、特征及面临的挑战。借鉴东京无废管理经验,并结合我国城市废物治理的特殊性,提出从完善政策制度、弥合管理碎片化、鼓励精益生产和循环经济、倡导绿色消费和垃圾分类共识等方面加快国内无废城市建设的政策建议。

电子商务零渠道销售同非法传销有天壤之别

电子商务零渠道销售,是光天化日之下的“白社会“运作模式,是参与者共赢的经营模式;而非法传销是“黑社会“运作模式,是层层盘剥、互相欺诈的经营模式.     

The Link Between Wages and Productivity in Spain

This paper examines the effect of productivity on wages for Spanish industrial sectors by developing a model that captures effects from both sector‐specific and aggregate variables. The results show that a dual behaviour can be inferred, at the sector level, in the wage‐setting mechanism. It is also found that the linkage between wages and productivity varies over time. Some explanations for the increase in wage dispersion are provided, focusing on the increasing decentralisation in wage bargaining after 1986. Finally, we cast some light on the theoretical structure underlying the labour market.
