Last week, I recorded a live podcast in Munich (yes, with real humans, not AI) about our research on giving behaviour, using a Dutch TV show where people donate to those in financial need. 🎙️

Presenting our work using Dutch TV show data to study altruistic motives all the way in Beijing at Peking University. A great group to visit.

Nottingham as I see it. It remains my favourite city, and it was great to be able to be back for a brief visit @uoncedex.bsky.social

Plus, the department ranks among the top economic departments in the UK.

And Colchester itself is also a great place to live.

The university is near to London, but also near the coast. Hence, you could select the lifestyle that best fits you.

I will be working in Munich for four weeks in July! Let me know if you are in the area and want to meet up.

Thanks to @valeriaburdea.bsky.social and @econmunich.bsky.social for the hospitality!

ResearchGate is recommending me my own research.

To be fair, it is the research I am generally most interested in 😅

Highly recommend Jesse Eisenberg’s “A Real Pain”. A very beautiful and layered movie

To sum up, we examined giving behavior using a Dutch TV show and find that while both utilitarian and equity & desert considerations are important drivers of donation decisions, utilitarian considerations are considerably more important.
September 11, 2024 at 8:21 PM
These conclusions are highly robust across a wide range of different specifications.
September 11, 2024 at 8:21 PM
Interestingly, both the regression and the dominance analysis show no indication that people discriminate on age, gender, or attractiveness in their giving decisions.
September 11, 2024 at 8:21 PM
Impact thus matters more than responsibility. This is backed up by a dominance analysis that decomposes the overall fit into the additively separate contributions of each variable. Impact is approximately 2.4 times as important as responsibility for understanding giving behavior.
September 11, 2024 at 8:20 PM
Donations increase strongly with impact and decrease moderately with responsibility. A one-standard-deviation increase in impact leads to a 6.2 percentage point rise in the share received, while a similar increase in responsibility lowers it by 2.7 percentage points.
September 11, 2024 at 8:20 PM
These were simple univariate analyses. However, impact and responsibility judgments are strongly negatively correlated. To separate their effects on donation decisions, we use Dirichlet-multinomial regression
September 11, 2024 at 8:20 PM
Responsibility perceptions matter too. This figure shows the shares given when candidates are ranked by their control over their situation. More money went to those with less control: the most control received 24%, intermediate 36%, and least control 40% on average.
September 11, 2024 at 8:20 PM
We study how these ratings relate to giving behavior. This ternary plot shows the shares received by candidates who ranked highest, middle, or lowest on impact in an episode. Impact matters: on average, top-ranked candidates received 44%, middle 34%, and lowest 22% of the total.
September 11, 2024 at 8:19 PM
We have data on giving in 55 episodes. But how do we measure the perceived impact of giving, or the perceived responsibility of the candidate? We conduct laboratory sessions at Maastricht University where we ask Dutch participants to rate candidates on these dimensions!
September 11, 2024 at 8:19 PM
The show offers a unique opportunity to study giving: audience members donate under controlled conditions, choosing between three cases without personal connection. This setup resembles the impartial spectator design used in lab studies on moral preferences.
September 11, 2024 at 8:19 PM
In total, 10.000 euros is thus divided in each episode. Below is the outcome for the three candidates just introduced.
September 11, 2024 at 8:19 PM
Each audience member is endowed with €100 and must donate this amount to one of the three candidates at the end of the episode.
