A positive analysis of deposit insurance provision: Regulatory competition among European Union countries

We consider the provision of deposit insurance as the outcome of a non-cooperative policy game between nations. Nations compete for deposits in order to protect their banking systems from the destabilizing impact of potential capital flight. Policies are chosen to attract depositors who optimally respond to the expected return to deposits, which depends on deposit insurance levels, systemic risk and transaction costs. We identify both defensive and beggar-thy-neighbour policies. The model sheds light on the European banking crisis of 2008 in which individual nations ratcheted up their deposit insurance levels.     

欧美金融衍生品监管改革进展及对我国的启示

2008年金融危机让各国认识到高杠杆金融衍生品的风险以及加强监管的必要性。危机后,欧美地区加强了对金融衍生品的监管,在规范市场方面取得了重要突破,对于金融衍生品市场处于起步阶段的中国具有一定借鉴意义。     

中国清末民初银本位下的汇率浮动:影响和启示

清末民初,银本位下的中国货币对大多数金本位国家的货币汇率自由浮动。浮动汇率并非影响中国国际收支和宏观经济的主要因素:在汇率大体持续贬值情况下,中国贸易逆差不断增大;汇率贬值有利于刺激外商直接投资和侨汇流入,弥补贸易逆差。关键问题是中国货币状况乃至整体经济活动受制于白银数量,容易大起大落。当前中国汇率弹性有待提高,对货币调控造成较大制约。我国汇率浮动早已有之,不必过于担心,中国完全具备主动加快汇率改革的条件。     

基于Meta分析的供应链网络嵌入性与协同创新绩效关系研究

供应链企业在合作中相互产生嵌入行为对高效整合链上资源以提高协同创新绩效至关重要,然而,两者之间的关系至今尚未形成一致性研究结论。本文利用Meta分析方法,以60篇相关文献、118个效应值、17911个独立样本作为研究对象,探究了网络嵌入性及各维度与协同创新绩效的整体效应,并运用亚组分析明晰了调节变量在两者关系中的调节作用。研究表明：网络嵌入性及其子维与协同创新绩效具有显著的正相关关系。另外,行业类型、区位因素、绩效类型及实证研究方法的不同均会导致研究结果不一致。本研究结论在一定程度上为网络嵌入性与协同创新绩效的关系研究提供了理论依据,同时也为供应链企业通过网络嵌入性提高创新能力提供了可资借鉴的参考思路。     

“三元悖论”与人民币汇率制度改革浅析

"三元悖论"作为经典的金融理论之一,反映了开放经济条件下汇率稳定性、资本自由流动性和货币政策独立性三者不可兼得的矛盾,为我国2005年7月21日开始实行的"以市场供求为基础、参考一篮子货币进行调节、有管理的浮动汇率制度"提供了理论依据。通过对我国经济中的"三元"即资本流动性、货币政策独立性以及汇率制度进行分析,在世界经济全球化和资本自由流动性不断增强的背景下,为保持我国货币政策的独立性,在2005年汇率改革的基础上,应该进一步扩大人民币汇率的浮动区间并研究、完善、及时调整货币篮子的币种及其权重,改善央行在外汇市场的干预机制,同时不断完善外汇市场产品和交易制度以及稳步推进利率市场化改革。     

Asset allocation in markets with contagion: The interplay between volatilities,jump intensities,and correlations

We study the impact of financial contagion on the dynamic asset allocation problem of a CRRA investor facing an incomplete market with two risky assets. We apply a Markov chain regime-switching framework with state-dependent jump intensities, diffusion volatilities and diffusion correlations. The key model feature that a switch to the bad contagion regime is triggered by a loss in one of the risky assets allows for the implementation of a hedging demand against contagion risk. Moreover, a state-dependent diffusion correlation combined with heterogeneity in jump intensities and volatilities can, e.g., generate a flight to quality effect upon a systemic jump.     

我国外汇储备的溢出效应研究——基于引力模型的分析

本文采用2000-2015年199个国家和地区的外汇储备面板数据,基于引力模型理论,考察了我国高额外汇储备的溢出效应及对全球资产配置的影响。研究发现:我国外汇储备具有随地理距离递减的空间外溢效应,双边汇率制度关联会增加外汇储备持有比例的相似程度,而且这种溢出效应更多地表现在与中国金融发展水平类似、资本账户开放程度相近的国家之间。上述结论凸显了国家间加强外汇储备合作调整的战略意义。探究我国外汇储备的溢出效应,有利于发展中经济体更好地理解外汇储备的变动逻辑,对于完善外汇储备管理体制,参与国际宏观经济政策协调机制均具有一定的积极意义。     

银行监管的微观基础和战略监管体系选择

本探讨了银行监管的微观基础，认为在信息不对称以及银行业不完全竞争的作用下，银行业具有内在的不稳定性，需要外部监管力量的支撑来维护稳健经营，但是政府机构监管作为监管垄断力量会引发一系列新的道德危害从而导致监管失灵。中详细分析了各种重要的监管措施带来的正负影响，在此基础上提出监管的战略体系至少应当包括监管、激励结构、市场约束和公司治理。     

Investment bank monitoring and bonding of security analysts’ research

We assess investment banks’ influence over the agreement between their analysts’ research behavior and their clients’ interests, in the post-reform era. Competing banks discipline their analysts with worse career outcomes for producing biased reports, issuing shirking reports, and for involvement in the earnings guidance game, showing meaningful monitoring of their analysts. Highly reputable banks provide more monitoring discipline of their analysts and bonding of their moral hazard than other banks. The findings agree with the banks taking responsibility for aligning analysts’ behavior with clients’ interests.     

Towards a measure of financial fragility

The paper proposes a measure of financial fragility that is based on economic welfare in a general equilibrium model calibrated against UK data. The model comprises a household sector, three active heterogeneous banks, a central bank/regulator, incomplete markets, and endogenous default. We address the impact of monetary and regulatory policy, credit and capital shocks in the real and financial sectors and how the response of the economy to shocks relates to our measure of financial fragility. Finally we use panel VAR techniques to investigate the relationships between the factors that characterise financial fragility in our model, i.e. banks’ probabilities of default and banks’ profits – to a proxy of welfare.
