- We analyze household-level changes in alcohol consumption in response to pregnancy. Using scanner data, we identify households with a pregnant household member. Within an event study and a dynamic difference-in-differences estimation, we find that during a first pregnancy, households reduce their alcohol purchases by 36%. After pregnancy, purchases of alcohol are 34% lower than before pregnancy. We do not find any effect during the second pregnancy. One possible explanation for our result is that lower consumption during pregnancy changes habits and reduces consumption in the long term. We discuss other explanations and comment on policy implications.

Empirical essays on choices under stress, preferences and consumption
- 2019
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This doctoral thesis consists of four self-contained chapters on different topics in Behavioural Economics.“The Impact of Stress on Risky Choice: Preference Shifts or Noise” examines whether risk preferences shift under stress, taking into account the possibility that more mistakes are made in decision-making under stress.“The Effect of Stress on Consumers’ Estimation of Food Consumption Levels: Evidence from a Lab Experiment” examines if consumers overestimate their food consumption levels under stress, which could lead to food waste.“The digit ratio (2D:4D) and economic preferences: no robust associations in a sample of 330 women” examines the effect of the digit ratio on economic preferences with an aim to replicate previous studies.“Pregnancy and Alcohol Purchases: Evidence from Scanner Data” examines how households adjust their alcohol purchases and fruit and vegetable purchases from before, to during and after pregnancy.

Tidskriftsartikel (refereegranskat)abstract
- We analyze the impact of acute stress on risky choice in a pre-registered laboratory experiment with 194 participants. We test the causal impact of stress on the stability of risk preferences by separating noise in decision-making from an actual shift in preferences. We find no significant differences in risk attitudes across conditions on the aggregate, using both descriptive analyses as well as structural estimations for risk aversion and different noise structures. Additionally, in line with the previous literature, we find statistically significant evidence for lower cognitive abilities being correlated with more noise in decision-making in general. We do not find a significant interaction effect between cognitive abilities and stress on noise levels. © 2022. The authors.

The digit ratio (2D:4D) and economic preferences: no robust associations in a sample of 330 women

Tidskriftsartikel (refereegranskat)abstract
- Many studies report on the association between 2D:4D, a putative marker for prenatal testosterone exposure, and economic preferences. However, most of these studies have limited sample sizes and test multiple hypotheses (without preregistration). In this study we mainly replicate the common specifications found in the literature for the association between the 2D:4D ratio and risk taking, the willingness to compete, and dictator game giving separately. In a sample of 330 women we find no robust associations between any of these economic preferences and 2D:4D. We find no evidence of an effect for sixteen of the eighteen total regressions we run. The two regression specifications which are significant have not previously been reported and the associations are not in the expected direction, and therefore they are unlikely to represent a real effect.
