  text: "<jats:title>Abstract</jats:title><jats:p>The use of structured measuring
    systems to prevent wall slip is a common approach to obtain absolute rheological
    values. Typically, only the minimum distance between the measuring surfaces is
    used for further calculation, implying that no flow occurs between the structural
    elements. But this assumption is misleading, and a gap correction is necessary.
    To determine the radius correction <jats:inline-formula><jats:alternatives><jats:tex-math>$$\\Delta

    for specific geometries, we conducted investigations on three Newtonian fluids
    (two silicon oils and one suspension considered to be Newtonian in the relevant
    shear rate range). The results show that <jats:inline-formula><jats:alternatives><jats:tex-math>$$\\Delta

    is not only shear- and material-independent, but geometry-dependent, providing
    a Newtonian flow behaviour in a similar viscosity range. Therefore, a correction
    value can be determined with only minute deviations in different Newtonian fluids.
    As the conducted laboratory measurements are very time-consuming and expensive,
    a CFD-approach with only very small deviations was additionally developed and
    compared for validation purposes. Therefore, simulation is an effective and resource-efficient
    alternative to the presented laboratory measurements to determine <jats:inline-formula><jats:alternatives><jats:tex-math>$$\\Delta

    in the future.</jats:p>"

  text: 'This study examines the loan-pricing behavior of German banks for a large
    variety of retail and corporate loan products. We find that a bank’s operational
    efficiency is priced in bank loan rates and alters interest-setting behavior.
    Specifically, we establish that a higher degree of operational efficiency leads
    to lower loan markups, which makes prices more competitive and smoothes the setting
    of interest rates. By employing state-of-the-art stochastic frontier efficiency
    measures to capture a bank’s operational efficiency, we take a look at the bank
    customers’ perspective and demonstrate the extent to which bor-rowers benefit
    from cost-efficient banking. '
