-<h3>General Instructions</h3>
-<p>Welcome. You have already earned 5 dollars by showing up for this exercise.
-You can earn more, up to an extra 25 dollars, by participating in the exercise
-which will last for about one hour. You will participate in this exercise as a
-part of a group. Each group has five participants. Your group has been formed
-by randomly assigning you to FOUR other participants in the room. The amount
-of money you earn will depend on the decisions made by you and the rest of the
-group. That is, your earnings will depend on your decisions as well as the

-This exercise mimics decisions people make in irrigation systems. In each round you
-will receive 10 tokens which you can choose to keep or invest in the irrigation
-infrastructure (for example canals and water diversion structures). Depending on the
-state of repair of the irrigation infrastructure, it will be capable of directing
-water to your field when you use your water diversion structure (called an
-irrigation gate). Depending on the amount of water you can get to your field, you
-can grow crops. Depending on the number of crops you grow you earn tokens. Each
-token is worth 5 cents and you will be paid cash in private at the end of the
-experiment based on the number of tokens you earned.
+We will now start a practice round to help illustrate the experiment. Before each
+round in this experiment you will have a chat period of %d seconds where you can

-The experiment consists of a number of rounds. In each round you will first make a
-decision as to how much to invest in the irrigation infrastructure. Without periodic
-investment, the irrigation infrastructure will break down over time. Based on the
-combined contributions of all 5 participants in your group in each round, as
-explained below, your group can maintain the performance of the irrigation
-infrastructure. The condition of the irrigation infrastructure determines
-its capacity to deliver water which you can use to grow crops.

-<h3>Creating Irrigation Infrastructure</h3>
+<h3>Facilitator Instructions</h3>
<p>
-After the chat period ends you and each other participant will be given 10 tokens.
-You must then decide what to do with these tokens. You may decide to invest in the
-irrigation infrastructure or to keep the tokens. If you keep the tokens you will
-earn at a minimum 10 tokens X 5 cents = $0.50 for each round. If you do this every
-round after twenty rounds you will end up with at least $10 (plus any crops that you
-may be able to grow as we will discuss later). Your total earnings for
-participating in the experiment would then be at least $10 plus your show-up payment
-of $5, for a grand total of at least $15.
+Welcome to the facilitator interface. This interface allows you to control
+the experiment. You may only modify configuration parameters <b>before</b>
+you start the experiment by selecting the Configuration menu. When all the
+participants are ready to begin the experiment, you can start the experiment
+by selecting Experiment -> Start. After a round has been completed you
+will be able to view the statistics for all of the participants. You can
+begin the next round by selecting Round -> Start.
</p>
-<p>
-On the other hand, if you invest some of your tokens in the irrigation
-infrastructure, you may be able to earn more than this amount by growing crops. If
-the irrigation infrastructure is operating at near maximum capacity you can earn
-close to $1.50 each round. Thus if you grow crops you can roughly triple your
-earnings compared to doing nothing. The actual earnings depend on the decisions you
-and the other participants in your group make in terms of investment and when to
-grow crops.
-</p>
-<p>
-In each round the condition of the irrigation system declines such that its water
-delivery efficiency drops by 25%. Investment is necessary to keep the irrigation
-infrastructure from deteriorating. If you decide to invest in irrigation
-infrastructure you must decide on the amount to invest out of your initial 10
-tokens. Keep in mind that the irrigation infrastructure must exceed a certain level
-before you can grow crops. The tokens invested by all participants in your group
-are added together and will total up to an amount 0 and 50 tokens. Each token
-invested increases the irrigation infrastructure efficiency by one percentage point,
-up to a <b>maximum of 100%</b>. This means that if the irrigation infrastructure
-efficiency is at 80% it would not make sense for your group to invest a total of 50
-tokens, as any investment beyond 20 tokens would be wasted. In the table below you
-can see the water delivery capacity measured in water units per second as a function
-of the condition of the irrigation infrastructure. When the infrastructure is at
-100% efficiency, 40 cubic feet of water per second (cfps) will be available. When the
-irrigation infrastructure efficiency falls below 45%, there is no capacity left for
-transporting water and thus there is no water available for anyone.
-</p>
-<p>
-Your initial irrigation infrastructure will start at 75% efficiency but <b>will
-carry over from round to round</b>. As an example, let's say that no one in a
-group invests any tokens in the first round. The irrigation infrastructure
-efficiency will be set at 75% for that first round. The table below lists the water
-delivery in cubic feet per second (cfps) corresponding to the irrigation infrastructure
-efficiency. If you look at the second to last row you can see that at 75%
-efficiency the irrigation infrastructure will deliver 35 cfps. So in the first
-round the group will have 35 cfps of water available to them.
-</p>
-<p>
-Recall that each round the irrigation infrastructure efficiency deteriorates by 25%,
-so at the start of the second round the infrastructure efficiency decreases to 50%.
-At this point all five members of the group decide to invest 7 tokens each. This
-increases the infrastructure efficiency by 35%, resulting in a total infrastructure
-efficiency of 85%. If you look at the table again you can see that an
-infrastructure efficiency of 85% will deliver 40 cfps.
-</p>
-<p>
-The actual amount of water that is available for the group depends on the amount of
-water available. Your group might have created an irrigation infrastructure with a
-capacity of 40 cfps, but due to lack of rainfall only 30 cfps is available. On the
-other hand, if the infrastructure capacity allows 30 cfps and 40 cfps of water is available
-to the system, only 30 cfps can be delivered.
-</p>
+]]>
+</entry>
-<p>
-To recap, at the beginning of each round you will be informed of the current
-irrigation infrastructure efficiency. You will then decide how many tokens (between
-0 and 10) to invest in the irrigation infrastructure. After everybody has made
-their decision, you will be notified of the condition of the irrigation
-infrastructure and the corresponding water delivery capacity.

-The animation above illustrates how water flows to each player when their gates are

-Access to water depends on your position as shown in the window. Water originates

-You can only get water to your field if you have water available to your position.
-Suppose that the total irrigation capacity available is 40 cfps and 40 cfps of water

-As another example, suppose that the canal system has been allowed to deteriorate

-<h3>How to grow crops</h3>
-<p>
-To start growing crops, click on the yellow button labeled "open gate".
-This will open your irrigation gate and allow water to flow to your field if it is
-available. The text on the button will change to "close gate" - if
-you would like to close the gate and stop extracting water from the canal, just
-click on the yellow button again. Your gate will close and the text on the button
-will change back to "open gate".
-</p>
-<p>
-The amount of water units (cubic feet) your field has received is shown on the
-screen, as well as the resulting amount of tokens earned from growing a crop.
-The number of tokens earned in each round depends on how much water you have
-diverted to your field. If you receive less than 150 cubic feet (cf) the crop has
-not received enough water to grow a crop and you will thus not receive any tokens.
-The maximum earnings are received when between 500 cf and 549 cf are diverted to
-your field. If more than 549 cf water is diverted to your field, this will
-negatively affect the growth of the crop (i.e. overwatering) and less tokens will be
-earned. In the table below you can see the amount of tokens earned for amount of
-water applied to your field.

-Your earnings at the end of the round depend on your investment and the number of
-tokens received for the crop. For example, suppose you invest 6 out of the 10
-tokens you are endowed with at the start of the round and you receive 333 cubic feet
-of water. Your total earnings will be the amount of tokens leftover from your
-initial endowment (10 - 6) plus the tokens you earned from your crop (15 tokens for
-333 cubic feet of water, see Table 2). The total number of tokens earned is 19
-($0.85 since each token is $0.05).

-We will now start with two practice rounds. This practice round will not
-contribute to your earnings – it is intended to acquaint you with the
-functioning of the exercise environment.
+<h3>Chat Instructions</h3>
+You may now chat for %d seconds with the other members of your group. You may
+discuss any aspect of the exercise with two important exceptions:
</p>
+<ol>
+<li>You are <b>not allowed</b> to promise the other participants
+side-payments or threaten them with any consequence after the experiment is
+finished.
+</li>
+<li>You are <b>not allowed to reveal your real identity</b>.</li>
+</ol>
<p>
-You will first chat via text with other participants in your group and then
-decide how much you wish to invest in irrigation infrastructure maintenance.
-After all investment decisions have been made you will begin the actual round
-and make real-time decisions on when to open your gates and irrigate your
-fields.
+We will be monitoring the chat traffic. If we detect any violation of these rules,
+we will have to remove <b>all members of the group where the violation occurred</b>
+from the experiment. That group will have to wait until the entire experiment is
+finished to receive payment.
</p>
<p>
-If you have any questions feel free to raise your hand and to ask your question.
-<b>Do you have any questions so far?</b>
+You can send messages by typing in the text field at the bottom of the screen
+and then pressing the return key or clicking the send button. The time left
+for the discussion is displayed with a progress bar above the text field at
+the bottom of the screen.
