Primary Outcomes (End Points)
|
Before
We consider five different outcomes that are based on voters’ evaluation of MPs. Voters evaluation of MPs whether (1) they represent the interests of their voters, (2) their own or third interests or the (3) values of their party as well as whether they are (4) competent or (5) hard-working. All outcomes are measured on a 1-7 Likert scale. We also plan to run heterogeneity analysis e.g. by self-reported political preference.

Experimental Design (Public)
|
Before
Each respondent is presented with 3-5 MP profiles. Each MP is randomly assigned the following characteristics: gender (male/female), marital status (single/married), party (center-left (SPD), conservative-right (CDU/CSU), liberal (FDP), green (Grüne) or left-wing (Die Linke), tenure in parliament (1,2, 3 or more legislative periods), mandate (directly elected or elected via party list), and published outside activities (no activities, Lawyer, Self-employed/ Entrepreneur, Member of Supervisory or Advisory Board, and speeches/ journalistic work) and respective earnings (no earnings, earnings between 1,000-3,500 EUR, 3,500-7,000 EUR and 7,000 EUR and more). We are primarily interested in the effect of the published outside earnings and activities on voters’ preferences.
|
After
First, we run a standard attention check. Then, each respondent is presented with 3 MP profiles. Each MP is randomly assigned the following characteristics: gender (male/female), marital status (single/married), party (center-left (SPD), conservative-right (CDU/CSU), liberal (FDP), green (Grüne) or left-wing (Die Linke), tenure in parliament (1,2, 3 or more legislative periods), mandate (directly elected or elected via party list), and published outside activities (no activities, lawyer, self-employed/entrepreneur, member of supervisory or advisory board, and speeches/journalistic work) and respective earnings (no earnings, earnings between 1,000-3,500 EUR, 3,500-7,000 EUR and 7,000 EUR and more). The ordering of the characteristics is randomized for each respondent. We are primarily interested in the effect of the published outside earnings and activities on voters’ preferences.

Randomization Method
|
Before
The characteristics of the MPs are randomized by the survey provider by a computer. The characteristics of the MPs are randomized by the survey provider by a computer. We apply the following quotas: (1) gender (65.4% male, 34.6% female), (2) marital status (33.7% single, 66.3% married), (3) party (center-left (SPD) 32%, conservative-right (CDU/CSU) 30%, liberal (FDP) 14%, green (Die Grünen) 18% or left-wing (Die Linke) 6%, (4) tenure in parliament (1 (25%),2 (26%), 3 or more legislative periods) (49%), (5) mandate (directly elected (47%) or elected via party list (53%)), and (6) published outside activities (no activities and no earnings (25%), all remaining combinations of activities (lawyer, self-employed/entrepreneur, member of supervisory or advisory board, and speeches/journalistic work) and respective earnings (earnings between 1,000€ - 3,500€, 3,500€ - 7,000€ and 7,000€ and more) have a probability of 6.25%. The percentages of the demographic characteristics of MPs reflect the composition of the German Bundestag in the legislative period starting from 2021 and the earning categories refer to the offical brackets in which outside earnings are reported.

We apply the following quotas: (1) gender (66% male, 35% female), (2) marital status (34% single, 66% married), (3) party (center-left (SPD) 32%, conservative-right (CDU/CSU) 30%, liberal (FDP) 14%, green (Die Grünen) 18% or left-wing (Die Linke) 6%, (4) tenure in parliament (1 (25%),2 (26%), 3 or more legislative periods) (49%), (5) mandate (directly elected (47%) or elected via party list (53%)), and (6) published outside activities (no activities and no earnings (25%), all remaining combinations of activities (lawyer, self-employed/entrepreneur, member of supervisory or advisory board, and speeches/journalistic work) and respective earnings (earnings between 1,000€ - 3,500€, 3,500€ - 7,000€ and 7,000€ and more) have a probability of 6.25%.

Planned Number of Observations
|
Before
We plan to have 4,000 respondents that are representative of German voters based on the latest federal election in the year 2021 along the following characteristics: age group, gender, East vs. West Germany, and party preference. Each respondent is presented with 3-5 independently randomized profiles of MPs. This gives us between 12,000 – 20,000 observations.
