Sticky prices or rational inattention – What can we learn from sectoral price data?

This paper derives stylised facts on sectoral inflation dynamics and confronts these facts with two popular theoretical models of price setting. Based on sectoral price responses to macroeconomic shocks estimated from an approximate factor model, we find that the frequency of price changes explains a relevant share of the cross-sectional variation of the speed and size of responses. Moreover, there is little evidence that the volatility of sectoral inflation due to idiosyncratic shocks dampens the size and speed of the responses to macroeconomic shocks. These findings support a multi-sector model with sticky prices rather than a rational-inattention model. We derive the results from different modelling and sampling decisions proposed in the literature, and we find that the explanatory power of the frequency of price changes for the speed of response to a macroeconomic shock proves robust in the face of these decisions. Other results are sensitive with respect to the choice of the factor model and the treatment of outliers.     

结“亭”组景的旷奥理论研究

回顾唐亭“袭古增妙”“结亭组景”的先锋实践，总结其模式，再认识柳宗元旷奥思想中“游之适”的内涵、要素、目标与价值追求，从“形适”与“意适”2个层面，提炼概括出时空节奏体验的“环-中”旷奥原型——“凌阻峭”与“抵丘垤”的2类空间感受。研究发现：秉承“游所之往”“风景求中”的价值取向，借助空间形态与序列组织调节游-息节奏、实现意境塑造，正是风景旷奥思想的“初心”。在与后来的造园组景、直至今天的绿水青山美之间，旷奥追求虽有间断但初心未变，对此“亭”功不可没。“亭”作为园林组景基本要素逐渐转化为中国园林典型的文化意象符号，作为实现风景旷奥初心的“结亭组景”，逐渐成为中国风景园林建筑的主题母语，开启了中国风景园林感受序列的新天地。进一步以上海松江方塔园与湖北2019园博园灵犀园为例分析探讨了旷奥理论结“亭”组景结合现代条件的运用思路与方法，以期不忘初心，与古为新，弘扬优秀的中华风景园林。     

对英语情景教学的几点思考

近年来情景教学法在中学英语教学中越来越普及,但在具体实施过程中教师会遇到许多困难.笔者认为,教师的"语言美、教态美、板书美"是实施情景教学的基础,而在创设客观真实情景的同时充分考虑各类学生的差异,充分利用学生的原有知识和经验是搞好情景教学的关键.目前我国中学英语教学大部分以大班为主,在教学过程中教师用英语授课、用直观教具创设情景、开展小型趣味游戏等是大班实施情景教学最有效的方法.     

Food contamination incidents: what do consumers seek online? Who cares?

• Consumers can play an active role in managing their health during food contamination incidents. With the popularity of the internet, consumers may seek online information to minimize health risks associated with the incidents. This study examines information demand and supply for consumers' online‐information seeking by investigating the search queries commonly used by consumers during the incidents and returned first page search results. We use a stage of change model to frame our hypotheses about information demand and stakeholder and agenda setting theories to frame our hypotheses about information supply. Results show that consumers' information seeking may progress through stages of precontemplation (seeking no special information), contemplation (seeking information related to the facts of the incidents), preparation and action (seeking information related to safety precautions and practices), and maintenance and termination (seeking no special information). Mainstream news media play the most important role in providing online information related to the facts of the incidents during the contemplation stage of consumers' information seeking. Online citizen journalism is the major online source for information related to safety precautions and practices during the preparation and action stage of information seeking. A diversity of other stakeholders also provide online information related to the incidents but are not primary information sources for consumers. We suggest that stakeholders, especially those who are responsible for providing accurate and timely information to consumers such as government agencies, establish online marketing strategies to make their information more accessible by consumers.

Regulation without Reason: The Deleterious Effects of Government Regulation on Private Pension Provision

In this article, the history of regulation in pensions in the United Kingdom is analysed, in particular with respect to defined benefit occupational pension schemes. A framework of criteria for effective legislation is developed. The original prudent person rule provided a good framework for legislation, but most subsequent regulation that has been enacted does not meet our criteria. Recently regulation has increased the cost and risk of individual schemes and the systemic risk in the system as a whole. The article finds that, in totality, regulation has been disastrous for these schemes, contributing to their demise. The article concludes by briefly outlining how effective regulation might have developed to produce a flexible and resilient system.
