An important issue in estimating cartel overcharges is to have a reliable estimate of the but-for-the-cartel price. While the cartel price is observable, the but-for-the-cartel price is not. A construction of the but-for-cartel-price evolution by assuming perfect competition, i.e. that price...

A crucial step in the quantification of damage in the context of damages claims is the estimation of the counterfactual price level: the price level that would have been observed in the absence of the cartel. This article discusses the Difference-in-Differences (“DiD”) estimation procedure...

Existing methods for data interpolation or backdating are either univariate or based on a very limited number of series, due to data and computing constraints that were binding until the recent past. Nowadays large datasets are readily available, and models with hundreds of parameters are fastly...

In this paper we study the zero frequency spectral properties of fractionally cointegrated long memory processes and introduce a new frequency domain principal components estimator of the cointegration space and the factor loading matrix for the long memory factors. We find that for fractionally...
