金融行业对实体行业的尾部风险传导研究——基于实体企业金融化视角

本文基于我国金融资本超额回报率的事实,在市场套利分析框架下实证检验了实 体企业金融化是抑制还是加剧了尾部金融风险溢出。数值模拟结果表明：从杠杆率来看,实体 企业金融化对杠杆率具有“双刃剑”效应,然而,实证结果发现,从长期经济后果来看,实体 企业金融化却显著提高了杠杆率,基于Altman-Z值的风险分析进一步发现企业破产风险显著 上升,从而加剧了尾部金融风险溢出。文章的研究结论有利于全面观察实体企业金融化带来的 的实际效果,也揭示了金融行业对实体行业的风险传导过程中的一个风险源,对于实体经济和 金融领域关于企业金融化效应的研究具有参考价值。     

Systemic event prediction by an aggregate early warning system: An application to the Czech Republic

This work develops an early warning framework for assessing systemic risks and predicting systemic events over a short horizon of six quarters and a long horizon of 12 quarters on a panel of 14 countries, both advanced and developing. First, we build a financial stress index to identify the starting dates of systemic financial crises for each country in the panel. Second, early warning indicators for the assessment and prediction of systemic risk are selected in a two-step approach; we find relevant prediction horizons for each indicator by a univariate logit model followed by the application of Bayesian model averaging to identify the most useful indicators. Finally, we observe the performance of the constructed EWS over both horizons on the Czech data and find that the model over the long horizon outperforms the EWS over the short horizon. For both horizons, out-of-sample probability estimates do not deviate substantially from their in-sample estimates, indicating a good out-of-sample performance for the Czech Republic.     

Financial crisis,GDP variation and earnings management in Europe

The purpose of this study is to examine the consequences of the financial crisis on the European companies’ in conjunction with earnings management practice. It focuses on financially distressed companies that audited by a big 4 auditor during recession years. The study makes use of discretionary accruals as a proxy for earnings management and studies the influence of big 4 auditor, in order to shed more light on possible causes for shifting earnings. The findings of the study provide evidence that financially distressed companies that audited by a big 4 auditor exhibit lower discretionary accruals. The results reveal that Greek and Spanish companies reduce earnings management manipulation during recession. In contrast, Portuguese, Irish and Italian companies show mixed results. They tend to reduce earnings management practices, but there are reasons that influence managers’ behavior to increase earnings management. The findings of this study can be useful for both investors and standard setting authorities.     

Dynamical macroprudential stress testing using network theory

The increasing frequency and scope of financial crises have made global financial stability one of the major concerns of economic policy and decision makers. This has led to the understanding that financial and banking supervision has to be thought of as a systemic task, focusing on the interdependent relations among the institutions. Using network theory, we develop a dynamic model that uses a bipartite network of banks and their assets to analyze the system’s sensitivity to external shocks in individual asset classes and to evaluate the presence of features underlying the system that could lead to contagion. As a case study, we apply the model to stress test the Venezuelan banking system from 1998 to 2013. The introduced model was able to capture monthly changes in the structure of the system and the sensitivity of bank portfolios to different external shock scenarios and to identify systemic vulnerabilities and their time evolution. The model provides new tools for policy makers and supervision agencies to use for macroprudential dynamical stress testing.     

Bailout uncertainty in a microfounded general equilibrium model of the financial system

This paper develops a micro-founded general equilibrium model of the financial system composed of ultimate borrowers, ultimate lenders and financial intermediaries. The model is used to investigate the impact of uncertainty about the likelihood of governmental bailouts on leverage, interest rates, the volume of defaults and the real economy. The distinction between risk and uncertainty is implemented by applying the multiple priors framework to beliefs about the probability of bailout.Results of the analysis include: (i) An unanticipated increase in bailout uncertainty raises interest rates, the volume of defaults in both the real and financial sectors and may lead to a total drying up of credit markets. (ii) Lower exante bailout uncertainty is conducive to higher leverage, which in turn raises moral hazard and makes the economy more vulnerable to expost increases in bailout uncertainty. (iii) Bailout uncertainty affects the likelihood of bubbles, the amplitude of booms and busts as well as the banking and the credit spreads. (iv) Higher bailout uncertainty is associated with higher returns’ variability in diversified portfolios and higher systemic risks, (v) Pre-crisis expansionary monetary policy reinforces those effects by inducing higher aggregate leverage levels. (vi) The larger the change in bailout uncertainty and the change in aversion to this uncertainty, the stronger the pre-crisis buildup and the deeper the ensuing crisis.A central policy implication of the analysis is that the vaguest is bailout policy prior to a crisis, the lower is the magnitude of investments destroyed or missed due to errors in evaluating bailout and other intervention policies. On the other hand, the clearer is bailout policy upon the eruption of a crisis, the smaller the contraction of credit and the destruction of investment activity.     

Spillovers among CDS indexes in the US financial sector

By employing the robust cross-correlation function approach proposed by Hong (2001), and conducting pre-tests for structural breaks in the variances as well as removing the causality-in-mean effects in the causality-in-variance tests, we investigate volatility and mean transmissions between the credit default swaps (CDS) indexes of three US financial sectors. We use daily series on five-year banking, insurance, and financial services sector CDS indexes at the sector level from January 2004 to December 2011. We find evidence of significant causality-in-mean effects running from the banking sector to the insurance and financial services sector CDS indexes and from the financial services to the insurance sector CDS indexes, suggesting the leading role of the banking and financial services sectors in terms of price discovery. Moreover, we find significant causality-in-variance effects from the financial services sector CDS index to that of the banking sector, implying the existence of information transmission and contagion from the former, the least regulated of the three. The implications of these findings on traders and policymakers are also provided.     

The role of institutional investors in propagating the 2007 financial crisis in Southern Europe

The 2007 financial crisis has affected Southern European companies (Spanish, Portuguese, Italian and Greek) more than others. From a Minskyan bubble-burst cycle perspective (Minsky, 1986), we study the relation between institutional ownership structure and corporate risk-taking for a sample of non-financial listed companies from Spain, Portugal, Italy and Greece for the period 2001–2014. Our results suggest that the financial deregulation process, that lead to the financialization of the world economy before the 2007 financial crisis and the favourable macroeconomic scenario encouraged corporate risk-taking in those countries. We also find that the lack of effective control mechanisms provided an incentive for investment funds to assume a proactive role, encouraging companies to overinvest in risky projects.     

Investing against the wind: contagion during the recent financial crisis

This article examines the effect of Warren Buffett’s investment in Goldman Sachs on 24 September 2008, during the subprime mortgage crisis. Although this event is arguably perceived to be the biggest expression of confidence in the financial market during the crisis, by conducting event studies, we do not find the major counterparties of Goldman Sachs displayed positive abnormal returns. Moreover, the abnormal return is not significantly related to the counterparty connection. We have similar findings on these financial institutions’ default probabilities using credit default swap.     

Creating financial statements using FRx within Microsoft Dynamics GP: Learning vs. teaching

This project requires you to create financial statements using FRx within Microsoft Dynamics GP, an enterprise system. The project emphasizes the learner-centered paradigm rather than a teacher-centered educational paradigm. Researchers have found great importance in the learner-centered approach in educating students, especially in information systems (Landry, Saulnier, Wagner, & Longenecker, 2008; Saulnier, Landry, & Wagner, 2008). Major differences exist between the two approaches; for example, the professor gives information and evaluates, and emphasizes the right answer in a teacher-centered approach. The professor coaches and facilitates, and emphasizes that students generate good questions and learn from mistakes in a learner-centered approach. This project utilizes the learner-centered approach, an effective approach for you to use in today’s environment.
