疫情危机与商业银行数字化对策研究

疫情危机的发生导致社会经济链条断裂,供应链流通受阻,并不断向上下游和其他节点传导,引爆诸多潜在的风险点,对社会经济产生巨大负面影响。本文以商业银行为例,研究疫情危机对商业银行的影响和管理危机的对策。研究表明,疫情危机的发生既是对社会经济秩序的一种破坏,同时也会在应对危机过程中催生出一些新的行业、产业或经营模式的变化。面对疫情危机,数字化不仅仅是商业银行应对危机的有效手段,更是商业银行转型升级的新方向。全面推进数字化对于其他行业应对疫情危机同样具有示范和借鉴意义。     

A Reconsideration of the Jumbo/Non-Jumbo Mortgage Rate Differential

Consistent with a series of recent papers, the interest-rate differential between mortgages eligible for purchase based on loan size by Fannie Mae and Freddie Mac and larger loans is estimated to be 22 basis points over the 1986–2000 period. This differential averaged 19 basis points for the 1996–2000 period. Other significant effects include: loans slightly above the conforming loan limit and originated late in a calendar year often have a lower rate that nearly fully anticipates their likely characterization as a non-jumbo loan after the conforming loan limit is indexed effective each January; loan-to-value ratios affect jumbo loan rates much more than they affect non-jumbo loan rates; loans located in non-metropolitan areas have a 3 basis point differential versus loans in metropolitan areas that is surprisingly small given the likely higher cost to service non-metropolitan loans and the higher degree of uncertainty about non-metropolitan collateral values; and estimated regional mortgage rate differentials have narrowed through time.     

Contagion Effects from the 1994 Mexican Peso Crisis: Evidence from Chilean Stocks

The contagion, or informational spillover, effects of the 1994 peso crisis from the Mexican market to the Chilean market, and to the Chilean American Depository Receipts (ADRs) trading in the U.S., are examined. Significant excess returns are observed for Chilean stocks for the event dates of the Mexican Peso crisis, providing evidence of contagion effects. Significant excess returns on these Chilean ADRs are also observed for each of the five event dates associated with the Peso crisis, suggesting that the contagion effects spilled over to the ADRs. A multiple regression model shows that the spillover contagion effects were very efficiently transmitted from the Mexican market to the Chilean market to the Chilean ADRs. Multifactor regressions show that the most significant influence on the pricing of Chilean ADRs is the raw Chilean Index, rather than the Chilean Index expressed in U.S. dollars.

试论我国财税法律体系的完善

经济的和谐发展呼吁完善的财税法律体系。目前,我国传统财税法律体系已经不能适应和谐发展的新要求,以科学发展观为指导,创新财税法学研究方法和研究范式,构建新的财税法律体系和拓展财税法学的理论空间,已经成为财税理论研讨中的新趋势。因此,宜从我国财政危机的法律原因入手,分析产生这些问题的法治根源,并提出创新财税法治观念、构建新的财税法律体系的思路。     

Valuing Mortgage Insurance Contracts in Emerging Market Economies

We develop a new option-based method for the valuation of mortgage insurance contracts in closed form in an economy where agents are risk neutral. While the proposed valuation method is general and can be used in any market, it may be particularly useful in emerging market economies where other existing methods may be either inappropriate or are too difficult to implement because of the lack of relevant data. As an application, we price a typical Serbian government-backed mortgage insurance contract.     

Convertibility risk: the precautionary demand for foreign currency in a crisis

This paper presents theoretical work linking money demand to the perceptions of households about the risk that domestic currency may become inconvertible or that it may be devalued. An empirical investigation of the size of this effect is carried out using monthly data for Korea to estimate an augmented demand-for-money equation. It is found that the fear of inconvertibility arising from the 1997 Korean currency crisis may have caused broad money demand to fall by 4–5% points,equivalent to the loss of reserves of $6–7.5 billion (or about 30% of reserves as measured at end-November 1997). This is a revised version of IMF Working paper WP/2001/210; it was written while Professor Black was Senior Policy Advisor at the IMF Institute and Christofides and Mourmouras were staff members in the IMF’s Policy Development and Review Department. The views expressed are those of the authors and should not be attributed to the IMF, its Executive Board, or its management. For useful comments and suggestions we thank an anonymous referee, Tim Lane, Ydahlia Metzgen, Roberto Perelli, Tony Richards, Christian Mulder, Steve Russell, as well as seminar participants at the IMF Institute, the IMF’s Asia and Pacific Department, Federal Reserve Board, and Bank of Indonesia. We would also like to note similar (unpublished) empirical results using our approach by Dr. Rino Effendi for Indonesia and Angana Banerji for Russia     

商业银行信用风险评估的生存分析模型及实证研究

企业发生财务危机，不能归还到期贷款是商业银行信贷资产的主要风险来源，商业银行如何构建恰当的信用风险评估模型来预测企业的财务危机，从而避免这类信用风险的出现就显得尤为重要。本文以我国上市公司为研究对象，结合杜邦分析法建立了基于生存分析的信用风险评估模型，模型对于随机选取的预测样本，其提前1年、2年和3年的预测准确率分别达到86％、72％和68％。通过与Ahman模型、Ohlson模型预测结果的比较和鲁棒性检验的结果发现，该模型同时具有可以使用时间序列、无需样本配对、中远期预测能力强和高鲁棒性的特点．这些特点特别对于商业银行中长期信贷风险管理具有较高的应用价值．     

乡镇财政自给能力分析

乡镇财政危机目前作为一个重要问题成为各界关注焦点,乡镇财政赤字和负债数额巨大,乡镇财政自给程度到底有多大,本文运用财政能力系数指标来定量探讨乡镇财政的危机程度,通过全国五级财政自给系数纵向对比、分省区四级财政自给能力纵向和横向对比以及两个乡镇个案的财政自给系数,来揭示乡镇财政危机的制度内涵.     

Alternatives to blanket guarantees for containing a systemic crisis

This paper seeks to explain how policy actions undertaken at the outset of recent crises—particularly the issuance of extensive liquidity support and government guarantees—absorb off-budget fiscal resources and inappropriately constrain officials’ subsequent options for restructuring their country’s troubled financial and corporate sectors. Empirical evidence supports the commonsense view that the damage a crisis works on a country’s financial sector and on its real economy is lessened by taking market-mimicking actions that promptly estimate and allocate losses during the early stages of a crisis. The most important steps are to plan to call a timeout to separate hopelessly insolvent institutions from potentially viable ones and to provide haircuts, guarantees, and liquidity support in ways that protect taxpayers and avoid subsidizing insolvent institutions’ longshot gambles for resurrection.
