Inflation targeting credibility and sovereign risk: evidence from Colombia

This article relates to the literature on sovereign risk in developing countries. In particular, we present empirical evidence to address the effect of inflation targeting credibility on sovereign risk based on the Colombian experience. The findings denote that credibility is an important improvement in the institutional framework to reduce the sovereign risk premium.     

When is the risk of cooperation worth taking? The prisoner’s dilemma as a game of multiple motives

This experimental article helps to understand the motives behind cooperation in the prisoner’s dilemma. It manipulates the pay-off in case both players defect in a two-player, one-shot prisoner’s dilemma and explains the degree of cooperation by a combination of four motives: efficiency, conditional cooperation, fear and greed. All motives are significant but some become only significant if one controls for all remaining ones. This seems to be the reason why earlier attempts at explaining choices in the prisoner’s dilemma with personality have not been successful.     

The Gendered Nature of Poverty in the EU: Individualized versus Collective Poverty Measures

Due to the adoption of the household as a unit of analysis, researchers have failed to identify accurate measures of women's income poverty. This study proposes an individualized measure of European poverty to highlight gender differences in the economic crisis. Employing data from the European Union Statistics on Income and Living Conditions (EU-SILC) for the period 2007–12, it compares the household-based at-risk-of-poverty rate (ARPR) and the individualized financial dependency rate (FDR). The study shows that the gender gap in poverty in Europe is considerably higher when computed through FDR. Indeed, since the ARPR constitutes a proxy of the household's average conditions, it levels down gender inequalities within the household and also variations in individuals’ incomes over time. Only more detailed data collection on intrahousehold resource sharing will possibly allow the development of more precise and realistic indicators of women's and men's risks of poverty and financial dependency.     

基于云模型的装备制造业产业链风险评价

将云模型引入风险评价,对装备制造业风险等级进行量化。从产业链的视角,将专家调查法与熵权法相结合识别风险因素,将筛选出的具有显著影响的因素作为评价因子引入云模型,从而降低了风险评估结果的主观性。构建了产业链风险评价指标体系,提出了基于熵权-云模型法的风险评估方法,对装备制造业产业链风险进行了总体评估。通过分析评估结果,提出防范装备制造业产业链风险的对策建议。     

金融中介职能、会计质量与债券违约风险——海龙短期融资券案例分析

利用案例分析方法分析了短期融资券11海龙CP01的发行和兑付过程,发现债券发行公司在发行债券前后均存在会计质量、公司运营以及内部治理等方面的问题,包括评级公司、承销商和会计师事务所在内的金融中介机构并未对这些问题及时披露,而这不利于信用风险市场化体系的建立,阻碍了债券市场的长期健康发展。     

欧盟碳期货风险量化——基于GED-GARCH模型和VaR模型

以欧盟碳期货合约为研究对象,针对其反映的市场风险特点,采用GED-GARCH模型进行参数估计。结果显示:到期日的因素使得欧盟碳期货合约收益率序列的条件方差与历史信息之间存在联系;碳期货合约的到期日越久,其条件方差越依赖于历史信息,表明欧盟碳期货市场为弱式有效市场;欧盟碳期货合约收益率序列的波动会逐渐衰减,表明最终合约价格能够起到价格预示作用。再利用GARCH模型的参数估计结果,计算出不同置信水平下收益率序列的在险值,夯实实证研究结果。针对欧盟碳期货合约风险的量化研究表明,欧盟碳期货与碳现货的关系呈现出新兴市场的分割局面特征,进一步导致欧盟碳金融市场逐渐走向虚拟化。因此,在中国碳市场的建设中,应做到碳期货与碳现货交易相协调,做好碳金融市场上风险的量化和控制。     

P2P网络借贷市场对资本市场的风险溢出效应

构建Copula-GARCH模型,并利用2013—2016年中国P2P网络借贷市场、股票市场和债券市场的日收益率数据,实证研究了P2P网络借贷市场对资本市场的风险溢出效应。结果显示:P2P网络借贷市场与股票市场之间存在"跷跷板"效应,与债券市场之间呈现出较弱的联动效应;P2P网络借贷市场与股票市场和债券市场的上、下尾部相关性均很弱,风险溢出效应不显著。结论表明:在确保金融系统稳定的同时,中国可以适度发展P2P网络借贷行业。     

Risk aversion,fanning preference and volatility smirk on S&P 500 index options

This article proposes a novel way of pricing S&P 500 index options in the presence of jump risk. Our analysis is built upon an equilibrium option pricing rule for a representative agent economy. In particular, we use the weighted utility’s certainty equivalent to specify agent’s risk preference, which displays a fanning-out characteristic. We find that the fanning effect captures a remarkably large portion of the total market risk premium implicit in options. As a result, the model with fanning effect generates pronounced volatility smirks.     

The role of price risk in China’s agricultural and fisheries exports to the US

This article explores the effect of price risk on the US importers’ optimal allocation of agriculture imports between the major supplier, China, and other competing countries. We first modify a demand system to account for the impacts of own-price risk and cross-price risk, and then apply the model to 16 agricultural and fisheries commodities exported to the US. The estimation results show that importers are sensitive to price risks of 14 Chinese commodities. Comparisons between price risk–trade relations of agricultural and fisheries products and between trade effects of cross-price risk on Chinese goods and substitutes provide strong evidence for explaining the observed trade patterns. Our study highlights the importance of price stability in promoting international trade, especially from developing countries to developed countries.
