Computing a standard error for the Gini coefficient: an application to credit risk model validation

Resampling approaches were the first techniques employed to compute a variance for the Gini coefficient. Few authors showed that Gini's coefficient measure can be obtained from a synthetic ordinary linear regression (OLS) based on the data and their ranks, thereby providing also with an exact analytical standard error. We develop these techniques for assessing the quality of credit models and for measuring the confidence interval of Gini coefficient. A special attention is given to low defaults and/or small length datasets and low quality models. In consequence we develop a new sampling-based method (F-Gini) for measuring the standard error of the Gini coefficient more adapted for these situations.

Default probability assessment for low default portfolios through resampling methods

The aim of this paper is to address the validity of default probability models calibrated on datasets with very low (or none) number of defaults. For these cases the credit models produce very low default probabilities, thereby imposing the computation of their upper bound limits for a given confidence level. The few approaches, proposed by the specialized literature for computing the upper bound of the default probability are based on the confidence intervals computed via probabilistic, Bayesian or analytic methods. We propose a benchmark of these methods and we explore the cases for which they are the most suited for. We propose a new method for computing the upper bound of the default probability in low default portfolios, employing resampling approaches. For the special case of no default portfolios we investigate an adjustment based on non-Gaussian behavior of the distance to default. We address also the issue concerning the dependency between defaults using non-Gaussian copulas.

Risk Assessment for a Structured Product Specific to the CO2 Emission Permits Market

The aim of this work is to use a new modeling technique for CO2 emission prices, in order to estimate the risk associated with a related, structured product. After a short discussion of the specificities of this market, we investigate several modeling methods for CO$_2$ emission prices. We use these results for risk modeling of the swap between two CO2 related instruments: the European Union Allowances and the Certified Emission Reductions. We estimate the counterparty risk for this kind of transaction and evaluate the impact of different models on the risk measure and the allocated capital.

Optimal structure of Central Counterparties Clearing Houses for minimizing default risk

After the recent crisis Central Counterparties Clearing Houses (CCP) gain momentum with the new regulations concerning the clearing of over the counter derivatives A classic CCP has a multi-'tranche' structure that allows to absorb the losses generated due to members defaults. The 'tranches' are Initial Margin, Default Funds of the defaulter, CCP Equity, Default Funds of the remaining clearing members and Additional undertaking from survivor members. In the case of the default of a Clearing Member the loss will be amortized by each tranche depending on the magnitude of the exposure at that time.

Statistical Evidence of Tax Fraud on the Carbon Allowances Market

The aim of this paper is to show evidence and to quantify with forensic econometric methods the impact of the Value Added Tax fraud on European carbon allowances markets. This fraud mainly occurred at the beginning of between the end of 2008 and the beginning of 2009. In this paper we explore the financial mechanisms of the fraud and the impact on the market behavior as well as the reflexion on its econometric features. In a previous work, we showed that the European carbon market is strongly influenced by fundamentals factors as oil, energy, gas, coal and equity prices. Therefore, we calibrated Arbitrage Pricing Theory-like models and showed that they have a good forecast capacity. Those models enabled us to quantify the impact of each factor on the market. In this study, we focused more precisely on the benchmark contract for European carbon emissions prices over 2008 and 2009.

Aftermath of the VAT Fraud on Carbon Emissions Markets

The purpose of this paper is to recognize the effect of the VAT fraud upon the market prices and to assess the occurrence of money laundering on the carbon emissions market. We present an analytic breakdown of the MTIC pocketed funds and estimate the bearish impact of the VAT trade on the carbon prices. The VAT carousel could be also used for all the steps of money laundering given the lack of control and surveillance of various trading firms. Findings present an analytic breakdown of the MTIC pocketed funds and a bearish impact of 2-3 euros upon the carbon prices. We explain also the origin of a relative persistence of high volumes on the spot market, by proposing a model of placement, layering and integration steps on the carbon emissions market, similar with the VAT carousel. This paper is the first study that quantifies the market manipulation effect due to VAT fraud. The work is also unique as it provides with the first estimation of money laundered on the carbon emission market. EUA, VAT, carbon, money laundering

Market Manipulation and Moral Hazard: Can the LIBOR be Fixed?

The aim of this work is to focus on the recent allegations of LIBOR rates manipulation. We show clear evidence that the individual contribution of each bank in the LIBOR submission process did not have a relevant impact on the rates level. Only through a synchronized "cartel-type" effort banks were allegedly able to fix the interest rate with a significant difference. For the case of USD LIBOR we developed a factorial modeling that captures the its relationship with US Treasury rates and Credit Default Swap spreads. Under this hypothesis we rebuilt a theoretical LIBOR that can peak 1% above the observed LIBOR during 2008.

Cost of the MTIC VAT fraud for European Union members

The Value Added Tax fraud is one of the most endemic economic crimes within the European Union. Its most disruptive form, the Missing Trader Intra-Coumunitary scam represents a real threat for the further economic and fiscal integration of the Union. The aim of this paper is to expose the mechanisms and to assess the magnitude of the MTIC fraud based on macroeconomic data. A macroeconomic model using panel regression is developed in order to link the amount of VAT collected across the member countries and their respective trade gaps. Using this model the outliers are identified based on the difference between the theoretical VAT and the observed amounts. The results emphasize that the MTIC fraud alone accounts for almost 68 Beuros in 2013 across the Union members (excluding Croatia) representing 0.5% of Union's GDP.

The Carbon Crooks

Tom Heinemann's documentary Carbon crooks presents to the large public how the carbon trading industry has been exposed to massive theft and fraud. According to Europol the fraud exceeds more than 5 billion euro. And Denmark was one of the centers for the massive fraud. One of the most intensive frauds was a V.A.T. caroussel where several European countries was exposed to a fraud hardly seen before. (IMDB page)
