新时代中国城市土地集约利用若干问题的再认识

研究目的：基于中国城市土地集约利用研究现状，面向新时代要求，重新审视与厘清城市土地集约利用理论认知、评价标准、影响机制和优化调控等基本问题，为中国土地集约利用的理论完善和实践创新提供支撑。研究方法：理论分析法和推理演绎法。研究结果：（1）城市土地集约利用在理论认知上应由“三个阶段”转向“三个时期”；（2）城市土地利用集约度的评价标准应由静态指标转向动态耦合；（3）城市土地集约利用的影响机制研究应由封闭区域转向关联传导；（4）城市土地集约利用优化调控策略应由极限集约转向最优集约。研究结论：进入新时代，城市土地集约利用理论上可实现“不增地，多增效”甚至“地减量，效增加”，未来相关研究应重点关注存量和减量规划中建设用地与经济发展之间关系的变化特征，以及国土空间规划与土地利用计划管理改革下新的城市土地集约利用问题。国家相关规程中的集约评价标准须结合区域发展阶段进行“匹配性”修正，政策制定要考虑区域间的“关联性”和“传导性”进行精准化设计，治理方案应按照最优集约度的“动态性”进行差异化调控。     

Consumption as a social integration strategy in times of crisis: The case of vulnerable households

In this article, we focus on consumption in a context of economic hardship. From an empirical perspective, and using a qualitative methodology, we show how disadvantaged individuals and households maintain a level of consumption commensurate with the society in which they are integrated through a type of consumption conceived of here as “resilient”. Resilient consumption is characterized by being a type of expenditure oriented towards maintaining the role of consumer, that is, maintaining a minimum level of purchasing power, modifying to this end both the level and the structure of consumption, both of which are key elements in the resilience process. We identify five main strategies used by households that modify and restructure the consumption of basic goods and necessities in response to economic hardship. Key resilient consumption strategies include: reduction (cutting down on spending), substitution (replacement of one difficulty with another), compensation (pseudo‐consumption or reduced usage), transference (meta‐resilience) and integration (reinterpretation of difficulties as opportunities). We conclude that although consumption is a naturally resilient behaviour, in a crisis context, resilient practices focus on maintaining acquisition capacity in spite of reduced income.     

新冠肺炎疫情、金融市场震荡与金融危机

新型冠状病毒感染肺炎疫情在全球快速蔓延后,美国等国家金融市场出现大幅度震荡,历史罕见。金融市场震荡是疫情影响投资者信心,金融市场本身的风险需要释放,以及经济基本面悲观预期等因素共同作用的结果。目前来看,疫情对实体经济造成冲击,疫情应对情况也在很大程度上决定了金融市场震荡是否演化为全球金融危机,国外金融市场震荡对国内金融市场的传导需要审慎理性处理。     

The COVID-19 crisis: A public choice view

Many observers have been puzzled by the sight of otherwise freedom-loving citizens consenting to the stripping of their civil rights and the massive budgetary expansion of their governments in response to the COVID-19 pandemic. Conversely, governments who ‘kept their cool’ such as those of Brazil and Sweden were heavily criticised by the Western media. Adopting James Buchanan's contractarian approach, this article seeks to model how the interplay between citizens and their government is affected by a health crisis. Citizens' increased willingness to pay for improved control of risks is found to play a major role.     

Factors influencing buying behavior of Lebanese consumers towards fashion brands during economic crisis: A qualitative study

The purpose of this article is to contribute to an understanding of the impact of the Lebanese economic crisis on fashion buying behavior. It uses a qualitative approach by conducting semi-structured interviews with 29 Lebanese consumers. The study reveals that consumer fashion purchases are motivated by emotional, social, and functional drivers. It also indicates that subjective norms, such as societal and cultural values dictate buying behaviors. The findings provide further insights into social media and highlight its influence on shaping trends and making fashion products desirable. The article concludes that Lebanese consumers exhibit impulsive buying behavior, and explains how fashion brands can remain relevant amidst a wrenching economic crisis.     

Fair value accounting from a distributed cognition perspective

This study offers a unique interdisciplinary perspective on fair value accounting. The growing influence of esoteric financial instruments whose valuation is becoming increasingly complex makes it necessary to focus on actual valuation practices. Based on an extensive review, this paper regards fair value accounting for complex financial instruments as involving processes distributed among actors located inside and/or outside a reporting entity. It also draws attention to collaboration by organizations that apply their external and internal resources to perform complex financial valuations. Furthermore, it demonstrates that cases involving unusual market conditions underline the importance of human interactions to the valuation process.     

Floating a “lifeboat”: The Banque de France and the crisis of 1889

When faced with a run on a “systemically important” but insolvent bank in 1889, the Banque de France pre-emptively organized a lifeboat to ensure that depositors were protected and an orderly liquidation could proceed. To protect the Banque from losses on its lifeboat loan, a guarantee syndicate was formed penalizing those who had participated in the copper speculation that had caused the crisis bringing the bank down. Creation of the syndicate and other actions were consistent with mitigating the moral hazard from such an intervention. This episode contrasts the advice given by Bagehot to the Bank of England to counter a panic by lending freely at a high rate on good collateral, allowing insolvent institutions to fail.     

The dark and the bright side of liquidity risks: Evidence from open-end real estate funds in Germany

During the 6-month period from December 2005 to June 2006, the German Real Estate mutual fund industry suffered an unprecedented liquidity crisis. We investigate to what extend competing theories of liquidity crises help explain this event. Our results show that fundamental factors not only mattered for the liquidity outflow in normal times but also during the crisis. However, strategic complementarities accelerated the withdrawals during the crisis suggesting that pure panic behavior contributed substantially to the massive outflows. Thus higher liquidity buffers might help mitigating these tail events. Furthermore, we find that funds with a lower fraction of shares held by institutional investors suffered from less significant outflows suggesting that a segmentation of funds for different investor groups might help mitigate panics.     

Hedging house price risk with futures contracts after the bubble burst

This paper extends the existing literature on managing house price risk. While previous work finds that a hedger would have reduced a large amount of variance in housing returns in Las Vegas, Nevada using Chicago Mercantile Exchange (CME) futures contracts, we show that neither static nor dynamic strategies would have maintained an effective hedge during the significant decline in housing prices. The inability to hedge house price risk using CME futures contracts ultimately calls into question the long-term viability of housing futures.     

Did the value premium survive the subprime credit crisis?

We provide evidence that value stocks significantly underperformed growth stocks during the subprime credit crisis, despite a positive value premium before the crisis. The reversal in the value premium concentrates in financially constrained firms, suggesting it was due to the adverse influence of the crisis rather than confounding effects. These findings are robust to alternative financial constraint proxies and asset pricing models. The observation that value stocks are vulnerable to losses during extreme downturns like the crisis is consistent with them being riskier than growth stocks. Our findings have implications for the academic debate on the underlying cause of the value premium and for investors on the profitability of value investing strategies.
