Preference reversals in willingness-to-pay and choice (link is to older version on SSRN)
O'Donnell, M. & Evers, E. R. K. (2019, Journal of Consumer Research)
We document a robust and consistent difference in expressed preferences depending on whether they are expressed as choices or in willingness to pay.

Van de Calseyde, P., Zeelenberg, M. & Evers, E. R. K. (2018, Organizational Behavior and Human Decision Processes) 
Post-decision doubt increases regret. 

Evers, E. R. K., Inbar, Y., Blanken, I., & Oosterwijk, L. D. (2017, Management Science)
Policies targeting a desirable behavior can be framed as advantaging those who act desirably, or disadvantaging those who do not. We find that people prefer policies framed as disadvantaging those who do not act desirably when targeting obligations, but prefer policies that advantage those who act desirably when targeting voluntary behavior.

Evers, E. R. K., van de Ven, N., & Weeda, D. (2015, International Journal of Internet Science)
Application of social-comparison theory in online gaming environments. Buying status-enhancing items with real money leads to a decrease in status. 

Set-Fit Effects in Choice
Ellen R. K. Evers, Yoel Inbar, & Marcel Zeelenberg (2014, Journal of Experimental Psychology: General)
The organization of a set of items causes preference-shifts

Daniel Lakens, & Ellen R. K. Evers (2014, Perspectives on Psychological Science)
Overview and how-to of new methods that can be used to interpret published studies

Ellen R. K. Evers & Daniel Lakens (2014, Frontiers in Psychology)
We repeat Tversky's (1977) studies on diagnosticity. We find similar data as Tversky, however, when we eliminate a confounding factor, we do not replicate diagnosticity effects.

Working papers

Evers, E. R. K., O'Donnell, M. & Inbar, Y.
People judge fairnes and distribute outcomes based on surface characteristics

Mental Accounting, Similarity, and Preferences Over the Timing of Outcomes
Evers, E. R. K. & Imas, A. O.
The integration and segregation of outcomes in Mental Accounting is constrained by similarity

Inbar, Y. & Evers, E. R. K.

Evers, E. R. K., Inbar, Y, Loewenstein, G., & Zeelenberg, M.
We find that people prefer sets that exhibit high order. This preference leads to violations of normative choice theory.

Don't use Poisson regressions for count data, they are bad.

A pre-registered, multi-lab non-replication of the action-sentence compatibility effect (ACE). (Psyarxiv) 
Morey, R., Kaschak, M. P., .......
One of the most famous embodied cognition effects does not appear to be reliably detectable.

Biased estimations of change
Evers, E. R. K., & Keren, G.
People generally underestimate large quantities more than smaller ones. As a consequence, portrayal of change in relative (i.e., %) or absolute terms leads to systematic under- or over-estimation.
