Try using the trigger property for this: doc

$(document).ready(function () {
  $("#Year").select2({ width: '75px' });
  $("#Year").children("option:last-child").attr("selected", true).trigger('change');
})
<link href="https://cdnjs.cloudflare.com/ajax/libs/select2/4.0.4/css/select2.min.css" rel="stylesheet" />
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.0.0/jquery.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/select2/4.0.4/js/select2.min.js"></script>

<select id="Year">
  <option value="2017">2017</option>
  <option value="2018">2018</option>
  <option value="2019">2019</option>
</select>
