PhD Defence: Gosse Alserda
In his dissertation ‘Choices in Pension Management’, ERIM's Gosse Alserda scrutinizes the complexity of choices in pension organization.
Gosse defended his dissertation in the Senate Hall at Erasmus University Rotterdam on Friday, 22 December 2017 at 11:30. His supervisors were Prof. Fieke van der Lecq and Prof. Onno Steenbeek. Other members of the Doctoral Committee are Prof. Benedict Dellaert (EUR), Prof. Alfred Slager (TIAS), Prof. Stefa Trautmann (Tilburg University), Prof, Jaap Bikker (University Utrecht), Prof. Patrick Verwijmeren (EUR).
Gosse Alserda (1989) received his propaedeutic Economics & Management from the University of Groningen in 2009 and his bachelor's degree Economics & Business Economics from Utrecht University in 2011.Thereafter he graduated from the Erasmus School of Economics, Erasmus University in 2013, where he received a master degree in Economics & Business, with a specialization in Financial Economics.
In 2013, Gosse started his PhD research at the Erasmus School of Economics and Erasmus Research Institute of Management (ERIM) under the supervision of Prof. dr. S.G. (Fieke) van der Lecq and Prof. dr. Onno W. Steenbeek. His main research interests are financial management and experimental economics, in particular related to pensions. As part of his research Gosse joined a research project at De Nederlandsche Bank (Dutch central bank).
The organization of pensions differs greatly across, and within, countries, and these differences affect the large number of stakeholders differently. The choices that underlie these differences tend to be very complicated, as they have to be balanced over the interests of different stakeholders over time.
The first two studies of this doctoral thesis analyse heterogeneity in pension plan risk preferences. Using an augmented risk preferences elicitation method, we find strong heterogeneity in latent risk preferences. Together with institutional differences these affect the optimal asset allocation. Therefore, it is worthwhile to elicit risk preferences.
The third study focuses on pension fund administration and investment costs. We show that there are large economies of scale for pension fund administrations, and modest diseconomies of scale for investment activities. Many pension funds have substantial X-inefficiencies for both administrative and investment activities. The study suggests that consolidation of pension funds may be efficiency enhancing.
The fourth study investigates pension fund discontinuity events. The occurrence and impact of these events is strongly dependent on the institutional setting of pensions. Stricter regulations increase the financial stability of the pension fund, but may reduce membership support through lower replacement rates. This trade-off influences the management of pension funds.
Taken together, this dissertation scrutinizes the complexity of choices in pension organization. Choices in pensions depend on the particular institutional setting of pensions and on specific pension plan member characteristics. These choices affect a great many stakeholders of pensions through different channels, both directly and indirectly.
