About me
Hi, my name is Dieter and welcome to my personal website!
I'm an economist by training and am working at the World Bank to find policy-relevant insights into sustainable finance, sovereign ESG, natural capital and government bonds. I explore these topics by applying econometrics and machine learning to various datasets, ranging from financial Bloomberg data to geospatial satellite data. I'm passionate about getting the key insights across with visualizations that tell a story. During my time, I've collaborated with central banks, tech companies, reinsurances, investment banks and even a space agency. I held visiting positions at Columbia Business School and the Dutch Central Bank.
What I do at the World Bank
I first joined the Bank in 2018 during my doctoral studies and am now part of the Long-Term Finance team, under the Finance, Competitiveness and Innovation Global Practice. You can read up on my latest work on World Bank blogs.
Sustainability-linked Bonds
"Issuances of green bonds, social bonds and other use of proceeds bonds continue to break new records and are projected to make up more than 40% of new issuances in Europe. Voices criticizing greenwashing, reporting standards and questioning whether green financing instruments are really adding to sustainable finance have become louder as well." (from Part 1)
Sustainability-linked bonds (SLBs) are promising alternatives. "At the end of the day, issuers want to be sure that their efforts are adequately rewarded, and investors want to know that they are having a real impact. Otherwise, SLBs will face the same questions about greenwashing and additionality. A KPI based on a transparent, scientific model addresses these concerns by construction." (from Part 2)

Sovereign ESG
Environmental, Social and Governance (ESG) investing has finally struck a chord with mainstream finance. With billions of dollars under sustainable management, ESG is no longer a niche topic but is becoming ordre du jour in the investment world. The scores, however, are not a one-fit-all solution for sustainability, especially on the country level. As part of the long-term finance team, I look at the ESG scores and use statistical methods to examine how they relate to national income, natural wealth or credit ratings.

Food Insecurity
As a modeling consultant for the Fragility, Conflict and Violence unit, I collaborated with leading insurance companies and global tech companies on the Famine Action Mechanism. In this project, I developed a stochastic model to understand and predict the population dynamics in food insecurity. See here (World Bank) and here (Washington Post) for press coverage of our project.

Visualizations
Dutch financial sector dependence on biodiversity
Biodiversity and nature are not distinct from the financial sector. In case of the Dutch pension funds, how dependency is there for each Euro invested?. The pension funds are coupled to business processes, which in turn are linked to the ecosystems. The dependency is based on two factors: how production processes are disrupted and the financial losses if a ecosystem service is lost. Open on DNB.nl website
Network stress testing: Rippling network
Banking systems can be represented as networks, where each node is a bank and each link could be a lending relationship, a common asset holding, a similar business model, etc. A central question is, how would a shock to a single bank ripple through the system? This visualization shows just that with a simulated network. Open in new window
BIS - international banking statistics
In an globalised world, countries are more connected than ever before. This relates to trade, business, travel but also to lending. This visualization shows how countries are linked to each other through their banks. Who lends to whom and how did the relationships evolve over time? Use this tool with data from the Bank of International Settlements to explore how banking changed over time. Open in new window
Chain of contagion
Financial contagion is the idea that if a bank goes into distress, it will also affect other banks connected to it. These in turn affect their peers etc. However, depending on the network structure, this effect can be amplified or dampened as it propagates through the network. This tool here explores this relationship for different network types and shock parameters. Open in new window
