关于旅游目的地环境容量约束的探讨:量化和模型分析

旅游目的地环境容量对旅游者的旅游活动和旅游产品的消费具有约束作用。本文环境容量约束加以量化,并引入到旅游产品消费的经济模型分析中,对如何在与旅游产品消费经济模型相关的研究领域中引入环境容量,以弥补因忽视环境容量约束而带来的不足之处进行了初步探索。此外,本文对如何解决环境容量约束对旅游产品消费的制约作用也做了简要的分析。     

非对称信息下农村金融市场结构对信贷配给的影响研究

在非对称信息的农村金融市场上,普遍存在着正规农村金融机构对农户的信贷配给。而目前垄断性的农村金融市场结构,加剧了农村金融机构与农户间的信息不对称程度,引发了农村信贷资金的外流,最终导致更为严重的信贷配给问题。因此,必须发展农户贷款担保组织和乡村银行,增强农村金融市场的竞争机制,更好地克服或减弱农村金融机构与农户间的信息不对称,切实解决农户贷款难题。     

进口信用证开立中银行的风险规避

进口信用证是国际业务结算诸品种中收益较高的一种.但是银行在进口开证业务快速发展的同时,也应重视风险的防范与控制,使之成为效益增长点而不是风险爆发点.     

信用违约风险传染模型的比较研究

本文试图对几种有代表性的模型进行比较,来分析由于建模方式的不同,而导致的对信用期权定价和对冲的结果的不同.如果将违约风险传染考虑进去,类似德隆帝国崩溃的事件,或许就能避免.     

基于博弈论的代建制研究

政府投资项目采用代建制的模式,实现了项目的专业化管理,有利于提高项目的投资效益。针对代建制实施的特点,运用博弈论的相关知识,依次建立了2 个模型 —— 激励相容约束模型和效率工资模型,并通过数学推理得到若干有益结论。     

论农村信用社的产权多元化

信用社有着自己的基本特征。中国农村信用社实践中存在三大误区:与集体经济相提并论;信用中介与一般中介特征相混淆;改革中出现行政化、机关化问题突出。因此,进行农信社的产权多元化是关键。本文分析的逻辑表明,我国农信社的改革应坚持两条道路,一是将多数农信社改造为商业银行;二是按照合作原则对部分农信社改造成真正意义上的信用社组织。     

Is ex-post credit risk affected by the cycles? The case of Italian banks

The objective of this research is to empirically examine if both credit and business cycle affect the ex-post credit risk (i.e. non-performing loans) in the banking system of Italy for the period 1995Q1–2014Q1. The increase in NPLs post-2008 has put into question the robustness of many European banks and the stability of the whole sector. It still remains a serious challenge, especially in Italy which is one of the countries that hit by the financial crisis. By employing fixed and random effects and a dynamic GMM estimation as econometric methodologies I find results that underline common causes for NPLs. Higher NPLs in Italy are mostly due to worse macroeconomic conditions (i.e. bad phase of business cycle) and due to excess credit. Through a Granger causality test, my arguments found even more support. Such findings can be helpful when designing macro-prudential as well as NPL resolution policies.     

Bond finance,bank credit,and aggregate fluctuations in an open economy

Corporate sectors in emerging markets have noticeably increased their reliance on foreign financing, presumably reflecting low global interest rates. The evidence also shows a rebalancing from bank loans towards bonds. To study these developments, we develop a dynamic open economy model where these modes of finance are determined endogenously. The model replicates the stylized facts following a drop in world interest rates; in particular, rebalancing towards bonds occurs because bank credit becomes relatively more expensive, reflecting the scarcity of bank equity. More generally, the model is suitable for studying interactions between modes of finance and the macroeconomy.     

Trade credit and the joint effects of supplier and customer financial characteristics

We examine how access to bank credit affects trade credit in the supplier–customer relationships of U.S. public firms. For identification, we use exogenous liquidity shocks to supplier firms in the form of staggered changes to interstate bank branching laws. Using a variety of tests, we show that supplier firms with greater access to banking liquidity offer more trade credit to their customers. We also show that when bank branching restrictions are relaxed in the supplier’s state, the supplier–customer relationship is more likely to survive.     

以廉政勤政简政为指引全面提升政府公信水平

近年来,我国政府公信力建设取得了巨大的成就,但也存在政策之间的协调性和行政体制的结构矛盾十分突出、政府公共服务和信息公开不能满足民众要求等问题. 要全面提升政府公信水平,就要深化行政体制改革,建立政府信用水平评价体系,推进政府信息透明化,完善政府对自身债务的管理,积极引导网络舆情.
