In a Constant Proportion Portfolio Insurance (CPPI) framework, a constant risk exposure is defined by the multiple of the strategy. This article proposes an alternative conditional multiple estimation model, which is based on an autoregressive quantile regression dynamic approach. We estimate...

We consider the problem of testing whether the observations X1, · · ·, Xn of a time series are independent with unspecified (possibly nonidentical) distributions symmetric about a common known median. Various bounds on the distributions of serial correlation coefficients are proposed:...

The objective of this paper is to provide a complete framework to aggregate different quantile and expectile models for obtaining more diversified Value-at-Risk and Expected Shortfall measures, by applying the diversification principle to model risk. Following Taylor (2008) and Gouriéroux and...

This study tests an international extension of the Asset Pricing Model (CAPM) based on the coexistence of two risk causes. The first cause is linked to the market portfolio and the second one is required by expectations about the variation of exchange rates. Through an application to various...

In the last decades, Corporate Social Responsibility (CSR) has been deeply studied. Many researchers focused on the best social report form underlining advantages, and they shown that these documents follow more and more often balance-sheets. This work analyses the relation between the writing...

This paper investigates the effects of home country banking regulations on the performance of foreign banks in Luxembourg?s financial center. We control for the main regulatory indicators, such as capital requirements, private monitoring, official disciplinary power and restrictions on bank...

Presumably, foreign banks open subsidiaries and branches in Luxembourg to perform different tasks. This paper studies the balance sheet structure of banks in Luxembourg, testing for differences across groups and across periods. Non-parametric methods yield several findings. First, specialisation...

The forecasting literature has identified three important and broad issues: the predictive content is unstable over time, in-sample and out-of-sample discordant results and the problematic statistical inference with highly persistent predictors. In this paper, we simultaneously address these...

This paper presents an analysis of the relationship between innovation, productivity and exports regarding the SMEs. The main research aim of this study consists in analyzing the hypothesis of firms’ conscious self-selection in the export markets. To measure innovation, we consider the...

This paper analyses the pricing behaviour of Luxembourg firms based on survey evidence. Luxembourg firms typically have low market share, many competitors and longstanding customer relationships. Price discrimination is frequently applied. A majority of firms use price review rules that include...
