Preferred Tax Rate

<p style="margin-bottom: 40px;">
  In order to determine the final bonus payment of you and the 7 others in your group, everyone in your group can now
  state his/her preferred tax.
  <br>
  <br>
  The tax is redistributive and has an efficiency cost. This means that a higher tax brings final boni closer together,
  but it also reduces final boni overall. The efficiency cost is low for small tax rates and increases with the value of
  the tax rate.
  <br>
  <br>
  Please note: Everyone in the your group is stating his/her preferred tax rate, like you do now. To be fair, we will
  choose among all the proposed tax rates at random, so your chosen tax rate has a 12.5% (1 out of 8) chance of being
  the applied tax rate for everyone in your group.
