4 2 Introduction Commissioned by Dr. Syngjoo Choi and Prof. dr. Wieland Müller, in the weekend of week 20 in 2009 a questionnaire was presented to the CentERPanel. Respondents had to allocate points to 'accounts'. The questionnaire was presented to 1960 panel members, of which 1182 respondents completely filled out the questionnaire (response percentage 60.3%).

5 3 Codebook This codebook contains the questionnaire as presented to the CentERPanel. The variable names are in bold and correspond to the names in the dataset. The routing of the questionnaire is shown in italic at the variable of interest. nohhold number (id) of the household nomem number (id) of the member in the household weeknr (weekno) year and week number when survey was conducted arandom random number from 1 to 25 brandom random number 1 or 2 blauw (blue) amount on blue (x-axis) at round arandom rood (red) amount on red (y-axis) at round arandom ronde (round) round number arandom kleur (color) brandom 1 = red, 2 = blue payoff payment in euro = amount on [color brandom] in round [arandom] * 0.25 [intro1] Deze vragenlijst bestaat uit een experiment op het gebied van individuele besluitvorming. Onderzoeksinstellingen in Groot-Brittannië en Nederland hebben geld beschikbaar gesteld om dit onderzoek uit te voeren. In dit experiment kunt u echt geld verdienen dat zal worden betaald in de vorm van CentERpunten. Wat u verdient is voor een deel afhankelijk van uw beslissingen en voor een deel van toeval. Leest u alstublieft de instructies zorgvuldig door omdat het om een aanzienlijk geldbedrag gaat. Gedurende het experiment spreken we over punten in plaats van euro's. Uw verdiensten worden berekend in punten en later aan u in geld uitbetaald. LET OP: U zult pas over een aantal weken het aantal punten aan uw tegoed toegevoegd zien. U zult dit niet meteen zien. 4 punten = 1 euro

6 [intro2] Dit experiment bestaat uit 25 ronden. Iedere ronde staat op zichzelf, maar de taak die u hebt, is steeds dezelfde. In iedere ronde hebt u de taak om punten te verdelen tussen twee rekeningen, die BLAUW en ROOD heten. Bij het begin van iedere ronde krijgt u een aantal mogelijke puntenverdelingen, waaruit u er één mag kiezen. Nadat u uw beslissing hebt gemaakt, kiest de computer op basis van toeval een rekening; elk van de rekeningen BLAUW en ROOD hebben een gelijke kans om gekozen te worden. Uw verdiensten in een ronde zijn de punten die u op de rekening hebt gezet die door de computer is gekozen, de punten die u op de andere rekening hebt gezet tellen niet mee. [test1] Om uw beslissing in iedere ronde te maken, maakt u gebruik van een grafiek. Hieronder ziet u hoe dat er uit ziet. De BLAUWE rekening komt overeen met de horizontale as en de RODE rekening komt overeen met de verticale as. Ieder punt in de grafiek stelt een verdeling voor tussen de BLAUWE en de RODE rekening. Bij het begin van iedere beslissingsronde ziet u een lijn die de mogelijke puntenverdelingen tussen de BLAUWE en RODE rekening voorstelt. In iedere beslissingsronde kunt u alleen een punt kiezen, dat op de lijn ligt. Voorbeelden van lijnen die u te zien kunt krijgen ziet u hieronder. In elke ronde selecteert de computer een lijn die de beide assen snijdt tussen de 10 en 100 punten en ten minste één van de assen op 50 of meer punten. De lijnen die voor u in de verschillende beslisronden worden geselecteerd zijn onafhankelijk van elkaar. [test2] In iedere ronde krijgt u van de computer een nieuwe lijn. Bij iedere keuze, mag u elke toewijzing van punten kiezen tussen de BLAUWE en de RODE rekening die op de lijn ligt. U mag er één punt kiezen. Hieronder ziet u een voorbeeld van zo'n lijn. Een mogelijke keuze is A, waarbij u 20.0 punten toewijst aan de BLAUWE rekening en 41.0 punten aan de RODE rekening. Een andere mogelijke keuze is B, waarbij u 55.4 punten toewijst aan de BLAUWE rekening en 17.6 punten aan de RODE rekening. Er zijn nog veel meer punten op deze lijn die u kunt kiezen dan alleen punt A of B. U mag ieder punt op de lijn kiezen. Alleen, u kunt maar één punt kiezen in iedere ronde. [test3] Op dit scherm kunt u even twee ronden oefenen. Om te beginnen klikt u op START. Dan krijgt u een lijn te zien met mogelijke puntenverdelingen in deze oefenronde. Om een toewijzing te kiezen gebruikt u de muis om de cursor op het computerscherm langs de lijn te bewegen naar de toewijzing die u wenst. (Om dit de doen, breng de cursor eerst in de buurt van het punt op de lijn.) U ziet dat u alleen toewijzingen kunt kiezen die op de lijn liggen. Als u weet welke beslissing u wilt nemen, klikt u op de linker muisknop om uw keuze te maken. Om de beslissing te bevestigen, klikt u op de OK knop. U wordt dan automatisch doorgestuurd naar de volgende ronde. Om een ander punt op deze lijn te kiezen, moet u op annuleren klikken. Nadat u twee keer een oefenronde hebt gedaan, zal de 'verder' knop verschijnen waarmee u naar de volgende informatiepagina kunt gaan. Dit is een oefenscherm. De keuze die u maakt, wordt niet opgeslagen. [intro3] Nadat u uw keuze hebt bevestigd, kiest de computer op basis van toeval één rekening; elk van de rekeningen BLAUW en ROOD hebben een gelijke kans om gekozen te worden. Als de BLAUWE rekening is gekozen, zijn uw verdiensten in de ronde het aantal punten op de BLAUWE rekening. De punten op de andere rekening worden niet meegerekend. Als de RODE rekening is gekozen, zijn uw verdiensten in de ronde het aantal punten op de RODE rekening. De punten op de andere rekening worden niet meegerekend. Vervolgens begint een nieuwe beslissingsronde. U krijgt van de computer een grafiek met een nieuwe lijn. U maakt dan weer een nieuwe keuze voor het aantal punten dat u op de BLAUWE en op de RODE rekening zet. De computer kiest dan weer tussen de BLAUWE en de RODE rekening. Dit proces herhaalt zich, totdat er 25 ronden geweest

7 zijn. Na de laatste ronde krijgt u een scherm met de mededeling dat het experiment beëindigd is. [intro4] Verdiensten Dit is de manier waarop bepaald wordt hoeveel u verdient in dit experiment. Na afloop van het experiment (na de 25e ronde), kiest de computer op basis van toeval één ronde uit de 25 ronden. Om dat te doen trekt de computer een getal van 1 tot en met 25. Dus de geselecteerde ronde is uitsluitend afhankelijk van toeval: alle ronden hebben een gelijke kans om gekozen te worden. Omdat slechts één ronde (van de 25 ronden totaal) op basis van toeval wordt geselecteerd en uitbetaald, is er geen terugkoppeling bij iedere ronde over de uitkomst (welke ronde is geselecteerd door de computer en de verdienste in die ronde). De geselecteerde ronde, uw eigen keuze in die ronde en het bedrag dat u krijgt uitbetaald worden op het scherm getoond. De punten worden omgerekend naar geld. Vier punten zijn 1 euro waard. U krijgt de punten bijgeschreven bij uw CentERpunten, waarbij 1 punt in dit experiment dus 25 CentERpunten waard is. [intro5] Het experiment gaat nu beginnen. U krijgt vanaf nu 25 schermen te zien met de grafiek en 25 verschillende lijnen. De computer kiest de lijnen op basis van toeval. Zoals uitgelegd in de eerdere instructies, is het uw taak om een punt te selecteren uit de mogelijke puntenverdelingen. Om de punt op de lijn te kunnen bewegen, breng de cursor eerst in de buurt van het punt op de lijn. Het kan even duren voordat het volgende scherm verschijnt. Om te beginnen klikt u op het volgende scherm op START. pointx01 to pointx25 intersection of the line and the x-axis pointy01 to pointy25 intersection of the line and the y-axis xc1 to xc25 respondents choice of point x-coordinate yc1 to yc25 respondents choice of point y-coordinate xs1 to xs25 starting point of the cursor on the screen x-coordinate ys1 to ys25 starting point of the cursor on the screen y-coordinate

In the second case panel members should mention that they do not know the income (-13) or do not want to tell (-14).

17 This questionnaire consists of an experiment in the area of individual decision making. Research institutions in Great Britain and the Netherlands have made money available to conduct this research. In this experiment you can earn real money that will be paid in the form of CentERpoints. What you earn, partly depends on your decisions and partly on chance. Please read the instructions carefully because it concerns a considerable amount [of money]. During the experiment we speak in terms of Points instead of euro. Your earnings will be calculated in points and later paid to you in money. 4 points = 1 euro Deze vragenlijst bestaat uit een experiment op het gebied van individuele besluitvorming. Onderzoeksinstellingen in Groot-Brittannië en Nederland hebben geld beschikbaar gesteld om dit onderzoek uit te voeren. In dit experiment kunt u echt geld verdienen dat zal worden betaald in de vorm van CentERpunten. Wat u verdient is voor een deel afhankelijk van uw beslissingen en voor een deel van toeval. Leest u alstublieft de instructies zorgvuldig door omdat het om een aanzienlijk bedrag gaat. Gedurende het experiment spreken we over punten in plaats van euro's. Uw verdiensten worden berekend in punten en later aan u in geld uitbetaald. 4 punten = 1 euro Verder

18 In this experiment you take part in 25 independent decision rounds which are very similar to each other. In every round you have the task to divide points between two accounts, which are called BLUE and ROOD. At the beginning of every round, you get a number of points, which you can put into the accounts. 1 After you have made your decision, the computer randomly chooses an account; each of the accounts BLUE and ROOD has an equal chance to be chosen. Your earnings in a round are the points which you have put in the account that has been chosen by the computer, the points which are in the other account do not count. In dit experiment neemt u deel aan 25 onafhankelijke beslissingsronden die sterk op elkaar lijken. In iedere ronde hebt u de taak om punten te verdelen tussen twee rekeningen, die BLAUW en ROOD heten. Bij het begin van iedere ronde krijgt u een groep van aantallen punten, die u op de rekeningen kunt zetten. Nadat u uw beslissing hebt gemaakt, kiest de computer op basis van toeval een rekening; elk van de rekeningen BLAUW en ROOD hebben een gelijke kans om gekozen te worden. Uw verdiensten in een ronde zijn de punten die u op de rekening hebt gezet die door de computer is gekozen, de punten die op de andere rekening staan tellen niet mee. Verder Vorige 1 Wieland: This is of course not the case and we need to tell the programmers to change this.

19 To make your decision in every round, you use a graph. Below you see how this looks like. The BLUE account corresponds to horizontal axis and the RED account corresponds to the vertical axis. Every point in the graph presents a distribution between the BLUE and the RED account. For example, the point in the graph below represents a division of 47.7 points to the BLUE account and 22.5 points to the RED account. Om uw beslissing in iedere ronde te maken, maakt u gebruik van een grafiek. Hieronder ziet u hoe dat er uit ziet. De BLAUWE rekening komt overeen met de horizontale as en de RODE rekening komt overeen met de verticale as. Ieder punt in de grafiek stelt een verdeling voor tussen de BLAUWE en de RODE rekening. Bijvoorbeeld, het punt in de onderstaande grafiek stelt voor de verdeling van 47.7 punten aan de BLAUWE rekening en 22.5 punten aan de RODE rekening. Verder Vorige

20 At the beginning of every decision round you see a line which presents a collection of possible point assignments, from which you can choose. Examples of lines which you might get to see can be seen below. In each round the computer selects a line which intersects the two axes between 10 and 100 points and at least one of the axes at 50 or more points. The lines which in the different decision rounds will be chosen for you are independent of each other. Bij het begin van iedere beslissingsronde ziet u een lijn die een verzameling van mogelijke puntentoewijzingen voorstelt, waaruit u mag kiezen. Voorbeelden van lijnen die u te zien kunt krijgen ziet u hieronder. In elke ronde selecteert de computer een lijn die de beide assen snijdt tussen de 10 en 100 punten en tenminste één van de assen op 50 of meer punten. De lijnen die voor u in de verschillende beslisronden worden gekozen zijn onafhankelijk van elkaar. Verder Vorige

21 In every choice, you can choose any division of points in the BLUE and the RED account which lies on the line. For example, below can you see that choice A on the line presents a decision that assigns 20.0 points to the BLUE account and 41.0 points to the RED account. Another possible choice is B, which assigns 55.4 points to the BLUE account and 17.6 points to the RED account. Bij iedere keuze, mag u elke toewijzing van punten kiezen tussen de BLAUWE en de RODE rekening die op de lijn ligt. Bijvoorbeeld, hieronder kunt u zien dat keuze A op de lijn een beslissing voorstelt die 20.0 punten toewijst aan de BLAUWE rekeningen en 41.0 punten aan de RODE rekening. Een andere mogelijke keuze is B, waarbij u 55.4 punten toewijst aan de BLAUWE rekening en 17.6 punten aan de RODE rekening. Verder Vorige

22 Click on START. To choose an assignment, you use the mouse to move the cursor on the computer screen to an assignment that you wish. You see that you can only choose assignments which lie on the line. If you know which decision you want to make, you click on the left mouse button to make your choice. To go to the next round you click on the OKAY button. You can practise the choice for an assignment on the line in the graph below. Klik op START. Om een toewijzing te kiezen gebruikt u de muis om de cursor op het computerscherm te bewegen naar de toewijzing die u wenst. U ziet dat u alleen toewijzingen kunt kiezen die op de lijn liggen. Als u weet welke beslissing u wilt nemen, klikt u op de linker muisknop om uw keuze te maken. Om naar de volgende ronde te gaan klikt u op de OK knop. U kunt de keuze voor een toewijzing even oefenen op de lijn in onderstaande grafiek.

23 After you have confirmed your choice, the computer randomly chooses one account; each of the accounts BLUE and ROOD has an equal chance to be chosen. If the BLUE account is chosen, your earnings of the round are the number of points in the BLUE account. If the RED account is chosen, your earnings of the round are the number of points in the BLUE account. The points in the other account will not be counted in. Then you are asked to make an assignment in another independent decision. This process is repeated until all 25 rounds are done. At the end of the last round you get to see on the screen that the experiment is over. Nadat u uw keuze hebt bevestigd kiest de computer op basis van toeval één rekening; elk van de rekeningen BLAUW en ROOD hebben een gelijke kans om gekozen te worden. Als de BLAUWE rekening is gekozen, zijn uw verdiensten in de ronde het aantal punten op de BLAUWE rekening. Als de RODE rekening is gekozen, zijn uw verdiensten in de ronde het aantal punten op de RODE rekening. De punten op de andere rekening worden niet meegerekend. Vervolgens wordt u gevraagd om een toewijzing te maken in een ander onafhankelijke beslissing. Dit proces wordt herhaald tot alle 25 ronden gedaan zijn. Aan het einde van de laatste ronde krijgt u op het beeldscherm te zien dat het experiment is geeindigd. Verder Vorige

24 Earnings Your earnings in the experiment will be determined as follows. At the end of experiment, the computer randomly chooses one of the 25 decision rounds. To do this, the computer draws a number between 1 and 25. The selected round depends exclusively on chance: all rounds have an equal chance to be chosen. The selected round, your own choice in this round, and the amount which you will be paid will be shown on the screen. The points are converted into money. Four points are worth 1 euro. You get the points added to your CentERpoints, where 1 point in this experimenting is worth 25 CentERpoints. Verdiensten Uw verdiensten in het experiment worden als volgt bepaald. Aan het einde van het experiment, kiest de computer op basis van toeval één beslissingsronde uit de 25. Om dat te doen trekt de computer een getal van 1 tot en met 25. Dus de geselecteerde ronde is uitsluitend afhankelijk van toeval: alle ronden hebben een gelijke kans om gekozen te worden. De geselecteerde ronde, uw eigen keuze in die ronde en het bedrag dat u krijgt uitbetaald worden op het scherm getoond. De punten worden omgerekend naar geld. Vier punten zijn 1 euro waard. U krijgt de punten bijgeschreven bij uw CentERpunten, waarbij 1 punt in dit experiment dus 25 CentERpunten waard is. Verder Vorige

25 On each of the following 25 screens you get to see a graph with randomly chosen budget lines. As explained in the earlier instructions, it is your task to select a point on the budget line. Since only one randomly chosen round (of the in total 25 round) will be paid out, there is no feedback about a round. It can take a moment before the next screen appears. To start you click on START. Op elk van de volgende 25 schermen krijgt u de grafiek te zien met de op basis van toeval gekozen budgetlijnen. Zoals uitgelegd in de eerdere instructies, is het uw taak om een punt te selecteren op de budgetlijn. Omdat slechts één ronde (van de 25 ronden totaal) op basis van toeval wordt geselecteerd en uitbetaald, is er geen terugkoppeling bij iedere ronde. Het kan even duren voordat het volgende scherm verschijnt. Om te beginnen klikt u op START. Verder Vorige

Measuring Time Preferences -Wave 1 3/32

31 {intro1} This questionnaire is about taking decisions. Research organisations in Great-Brittain and The Netherlands have supplied money for this study. During the first part of the questionnaire we ask you to distribute money between two points in time when you would receive the money. Then, questions about your household and some multiple choice questions will be asked. The money you earn in this questionnaire is real. Therefore, please read the instructions carefully. Thank you very much in advance for participating in this study! {intro2} In the first part of the study, you will choose 40 times between two dates to receive money, where the choice is always between sooner or later. After you have made all decisions, the computer will randomly select one of these decisions. You will receive the money based on this decision. Each of the 40 decisions has the same probability of being selected by the computer. Therefore, you should consider each of the 40 decisions as one that matters. At the end of the questionnaire, the selection of the computer will be shown, including the amount of money you will receive. Note: only if you completely fill out the questionnaire and if you provide an account number where we can transfer the money to, you will be able to receive money. {intro3} Before we describe an example of the choice situation, we will explain to you how the payment of money works. At the end of the questionnaire you will get the oppurtunity to provide an account number where you would like to receive the money. If an account number for your household is already known at CentERdata, you can choose to receive the money at this account. A different account number is also possible, but in that case, you will have to provide the account number at the end of the questionnaire. CentERdata will arrange with your bank that you will receive the money at the exact date or dates that you have chosen. We will make sure that with absolute certainty you will receive the amount at the date or dates that you have chosen. In case of problems with a payment, you can contact the CentERdata helpdesk, through phone number Measuring Time Preferences -Wave 1 4/32

32 {intro4} Now we will explain how you can make the choices. In this study we will talk about tokens instead of euro s. The tokens are exchanged for real money in the following way: four tokens are worth 1 euro. At every choice situation we will ask you to distribute tokens between two different points in time. During the first 20 rounds, you will choose between Thursday [June 23rd/September 15th] 2011 versus Thursday [September 15th/December 8th] The second date is exactly 12 weeks later than the first date. In the next screen you can see an example. {intro5a-d} To make your decision in each round, you will use a graph. You can see below what the graph looks like. The BLUE text describes the [vertical/horizontal] axis of the white square. This resembles the number of tokens at [June 23rd/September 15th]. The RED text describes the [horizontal/vertical] axis. This resembles the number of coins at [September 15th/December 8th]. Please look at the sloping black line cutting through the big white square. Each point on this line shows a possible distribution between the number of tokens at [June 23rd/September 15th] and [September 15th/December 8th]. In each of the first 20 rounds, the computer randomly selects a new line. The axes run from 0 to 100 tokens. In each round the computer selects a line that crosses the [vertical/horizontal] axis between 10 and 50 tokens and crosses the [horizontal/vertical] axis above the intersection with the [vertical/horizontal] axis and below 100 tokens. It is always possible to make the choice in such a way that you will receive more money at [September 15th/December 8th] than at [June 23rd/September 15th]. In each round you can choose one point at the line. The timeline at the top of the screen shows the different payment dates that are used in the choices. The current round number is shown at the right side of the screen. Below that number you can see the amount of tokens that are currently assigned to [June 23rd/September 15th] and [September 15th/December 8th]. Measuring Time Preferences -Wave 1 5/32

35 {intro6a-d} Below you can see two examples of choices. A potential choice is A, where you assign 35.1 tokens to [June 23rd/September 15th] and 20.1 tokens to [September 15th/December 8th]. B is another possible choice, where 5.7 tokens are assigned to [June 23rd/September 15th] and 60.5 tokens to [September 15th/December 8th]. In this example, if you shift your choice from point A to point B, then you can earn 40.4 tokens more at [September 15th/December 8th] by giving up 29.4 tokens at [23 juni/15 september]. Or vice versa, if your choice shifts from point B to point A, then you receive 29.4 tokens more at [June 23rd/September 15th] by giving up 40.4 tokens at [September 15th/December 8th]. There are many more points at this line for you to choose, other than point A or point B. You are allowed to choose any point on the line. Note however: only a single point can be chosen in each round. if arandom=1 and brandom=1: Intro6a Measuring Time Preferences -Wave 1 8/32

Then a line with possible token assignments will be shown for this practice round. To choose an assignment, use your mouse to move the cursor on the computer screen along the line, in the direction of the assignment that you would like to use. To accomplish this, first move the cursor near the point on the line. You will see that only assignments on top of the line are allowed. If you know which assignment you would like to choose, click on the left button of the mouse to choose the assignment. To record your choice, click on the OK button in the lower left corner. You will then be transferred automatically to the next round. To choose a different point on the line, please click the Cancel button. After playing two practice rounds, you will be automatically transferred to the next information screen. This is a practice screen. The choice you make, will not be recorded.

38 {Example screen:} {intro7} The experiment starts now. You will be shown two times 20 rounds. During the first 20 rounds, we ask you to assign tokens between the following dates: Thursday [June 23rd/September 15th] 2011 versus Thursday [September 15th/December 8th] The difference between these two dates is exactly 12 weeks. After you filled out the first 20 rounds, you will receive information about the second set of 20 rounds. First move the cursor near the the point on the line, in order to move the point on the line. It can take some time before the next screen appears. To start, click the START button in the next screen. {eerste 20 ronden} This is the real experiment.

Again, the axes run from 0 to 100 tokens. At the start of each round the computer selects a line that crosses the [vertical/horizontal] axis between 10 and 50 tokens and crosses the [horizontal/vertical] axis above the intersection with the [vertical/horizontal] axis and below 100 tokens. It can take some time before the next screen appears. To start, click the START button in the next screen. {tweede 20 ronden} This is the real experiment.
