Hi Ryan,<br /><br />Thanks for the prompt turnaround. And of course for the edits and for your encouragement.&nbsp;<br />I have a question about one sentence. It reads now as:&nbsp;<br /><br /><em>Most existing studies have analyzed fiscal unification in symmetric environments, i.e. under </em>assumption<em> that <strong>this</strong> does not represent reality for fiscal unions with substantial freedom for their members, such as the United States.&nbsp;</em><br /><br />What I tried to convey is that the assumption of&nbsp;symmetric environments in not realistic (for fiscal unions with substantial freedom for their members, such as the United States.)&nbsp;<br /><br />Should that sentence read:<br /><em>Most existing studies have analyzed fiscal unification in symmetric environments, i.e. under an&nbsp;</em>assumption<em>&nbsp;that&nbsp;does not represent reality for fiscal unions with substantial freedom for their members, such as the United States.&nbsp;<br /></em><br />or even<br /><br /><em>Most existing studies have analyzed fiscal unification in symmetric environments, i.e. under a too strong assumption&nbsp;</em><em>for fiscal unions with substantial freedom for their members, such as the United States.&nbsp;<br /><br /></em>Thanks in advance and I will be submitting another documents soon.<br />V<em><br /><br /></em>
