Current practice largely follows restrictive approaches to market risk measurement, such as historical simulation or RiskMetrics. In contrast, we propose flexible methods that exploit recent developments in financial econometrics and are likely to produce more accurate risk assessments, treating...

Under the new regulation based on Basel solvency framework, known as Basel III and Basel IV, financial institutions must calculate the market risk capital requirements based on the Expected Shortfall (ES) measure, replacing the Value at Risk (VaR) measure. In the financial literature, there are...

This study explores the stylized facts, volatility clustering, other highly irregular behaviour, and risk measures of cryptocurrencies' returns. By analysing bitcoin, ripple, and ethereum daily data we establish evidence of strong dependencies among analysed cryptocurrencies. This paper provides...

Elzinga & Mills (2011) trace the origin of the price/cost margin (P-MC)/P commonly used as an index of monopoly power in Abba Lerner's famous 1934 essay in the Review of Economic Studies. They also ascribe to Landes & Posner (1981) the more general version of the index for the case of a dominant...

Output and input market distortions manifest as wedges in the firm's first order conditions. The production approach to markup estimation recovers the markup wedge using the output elasticity for a variable and undistorted input. We show that using the revenue elasticity for any variable input,...

In this paper, we provide an assessment of the evolution of markups in Italy in the last twenty years. To this aim, we resort to both macro and micro data and estimation techniques, namely reduced forms accounting measures (price-cost margins) and production function model-based indicators. When...

This study examines the change in entering class median LSAT, a key input into the U.S. News & World Report rankings, between 1993 and 2004. Using multivariate regression analysis, the authors model several factors that can influence the direction and magnitude of this change. The study presents...

The purpose of this paper is to propose discrete-time term structure models where the historical dynamics of the factor (xt) is given, in the univariate case, by a Gaussian AR(p) process, and, in the multivariate case, by a Gaussian n-dimensional VAR(p) process. The factor (xt) is considered as...
