“Netspar has made an enormous contribution to the scientific foundation for the pension sector.”

Published on: 5 September 2025

Netspar, the knowledge network focused on bringing together science and the pension sector, is celebrating its 20th anniversary this year. We look back on these two decades with Anne Balter (theme coordinator at Netspar) and Rob van den Goorbergh (member of the Netspar Partner Research Council on behalf of APG). Which developments played an important role? And how have APG and Netspar benefited each other with respect to the renewed system? “Instead of making value judgments, we now focus much more on formulating the different characteristics of policy options.”

 

How has Netspar developed in the past twenty years?

Anne
: “Initially, Netspar was primarily a knowledge network that provided opinions. It is now more concerned with the question of under what assumptions a particular choice by a legislator, administrator, or participant might be attractive. Examples include the choice of exposure to investments, the legal state pension age, or the options that can be offered to participants. We now focus much more on the different characteristics of policy options. The final choice is up to politicians and other parties involved.”


Rob
: “APG has been one of the partners from the very beginning. Over the past two decades, Netspar has developed from a local platform into an international network of scientists involved in pension issues. Most of the partners come from the Dutch pension and insurance sector. Netspar has made an enormous contribution to the scientific foundation for decisions in the pension sector. The new pension contract and the substantiation of legislation have become much more professional, thanks in part to Netspar.”


How did APG and Netspar benefit from each other during those years?


Anne
: “There has been a great deal of interaction, including in the form of researchers being appointed to APG for a specific period of time. A recent example is the project around measuring participants’ risk and sustainability preferences. The regulator now requires such metrics, and many Netspar researchers have contributed ideas on how APG can implement this. In previous years, they also contributed ideas on measuring the value of intergenerational risk sharing and how to deal with shocks in life expectancy. Another example is the fight against the gray and white spots, i.e., people who are accruing insufficient or no pensions. In addition, after the failure of the Pension Agreement in 2011, Netspar contributed to normalizing the sour relations between the various parties involved. More recently, Jan Bonenkamp (ALM manager at APG, ed.), Bas Werker (professor at Tilburg University), and I conducted research into the standard method. This is the basis for how participants’ assets are distributed during the transition to the new system.”


Rob
: “The PhD student who worked with us at the time on research into measuring risk preferences was Jorgo Goossens. That helped us enormously in the services we started offering as a team for risk preference studies. This is very interesting research, which requires expertise from various disciplines. Not only investment specialists, but also IT professionals, actuaries, communication specialists, and people who know how to set up a survey and ask the right questions, who understand people. Jorgo is now an assistant professor at Radboud University Nijmegen, but still works at APG part-time. He has also expanded his field of research to include participant preferences for sustainability.

I think APG is one of the most active partners within the Netspar network. In total, around forty people from all parts of the organization play an active role in publications, webinars, and podcasts. They often do this in collaborations with Netspar scientists. For example, Anne and I worked with Nikolaus Schweizer to publish research on the prosperity effects of underestimating and overestimating risk appetite.”

Did Netspar and APG have any further dealings with each other in relation to the Future of Pensions Act, apart from the examples you already mentioned?

Anne
: “Yes. Together with Matthijs Kokken (ALM strategist at APG, ed.), Bas Werker and Theo Nijman investigated how you can reduce the risk of pension cuts in the new system. In addition, questions surrounding communication and choice guidance have naturally become increasingly important. And the Future of Pensions Act is certainly not perfect yet, so new topics are also coming to the table, such as adjustments to make purchasing power management more feasible.”

What do you mean by that last part?

Rob
: “Part of the investment policy is designed to provide a guaranteed return. This is determined on a nominal basis. In other words, the pension you receive is a fixed amount in euros, but the purchasing power of that amount depends on inflation. This means you are not protected against inflation shocks, but there are options for adding that protection. We discuss these things with Netspar.”


Anne
: “Another example is the survivor’s pension. This has been improved in the new system, but new risks have also arisen. One of these is that if you die before reaching retirement age after many years of employment, at a time when you are no longer an employee, there will not always be a survivor’s pension. These risks need to be examined. By continuing to ask these questions, Netspar makes it clear that not everything is working exactly as it should yet.”

 

Are there some more examples of that?

Anne
: “The main challenge now is to improve the ways in which we explain the new system to participants. It is more about a cultural shift towards a participant-oriented organization. How do you communicate in such a way that the benefits of collectivity and solidarity are clear? How do you offer choices, given that on the one hand we like to have lots of choices, but on the other hand we don’t really want to choose?”

Rob: “There are some critical comments to be made when it comes to communication. This is only now being taken seriously, as a kind of afterthought. But the technology behind the new system is in place, and it is quite complex. There are actually only a few experts who really understand it from A to Z. However, you do need to be able to explain the fairness of the outcomes to the average participant. If you had had those communication experts at the table from the start, the product would certainly have been different. So, the Future of Pensions Act is indeed not yet complete, and that also applies to this.”
