    Cash is still the most common means of daily payments. The large number of cash payments is supported by a costly distribution system in which retailers, banks and central banks participate. Currency is issued in a range of bank note and coin denominations to facilitate efficiency in cash payments. The purpose of this thesis is to study the performance of a currency range in practice. It presents a number of empirical studies on cash payments at the individual payment level, whereby cash payments are viewed as the outcome of a choice process. This type of analysis calls for labor-intensive data collection methods and the development of a sophisticated econometric model. This thesis introduces such a model for cash payments, and it reviews its application to three unique data sets of cash payments. The data concern payments in the Netherlands before and after the transition from the guilder to the euro in 2002, and payments in an experimental setting. The estimation results allow for an assessment of the use of different bank note and coin denominations in cash payments, and of possible preferences for one of more denominations. Currency research generally approaches currency use from a macroeconomic point of view. The novelty of this thesis is that it contributes to currency research by focusing on individual cash payments.Jeanine Kippers (1973) obtained her master´s degree in econometrics from the Erasmus University Rotterdam in 1997. In the same year she was employed by De Nederlandsche Bank. She participated in the preparations of the cash changeover from guilder to euro in 2002, and contributed to the development of a European cash distribution system and the restructuring of the national distribution system. During her employment at the central bank she started her research on currency use, which resulted in several papers that have been published or are currently under review. In January 2004 she joined the Pensionand Insurance Supervisory authority, as a policy advisor in the (international) field of insurance supervision

    Measurement of the top-quark mass in all-jets tt events in pp collisions at root = 7 TeV

    The mass of the top quark is measured using a sample of tt¯ candidate events with at least six jets in the final state. The sample is selected from data collected with the CMS detector in pp collisions at s√=7 TeV in 2011 and corresponds to an integrated luminosity of 3.54 fb−1 . The mass is reconstructed for each event employing a kinematic fit of the jets to a tt¯ hypothesis. The top-quark mass is measured to be 173.49±0.69(stat.)±1.21(syst.) GeV. A combination with previously published measurements in other decay modes by CMS yields a mass of 173.54±0.33(stat.)±0.96(syst.) GeV
