International political economy (IPE) is concerned with the dynamic interconnections between economic and political action at the international level.
In US, analysis is focused on the twin concepts of positivism and empiricism that maintain that knowledge is better obtained by calling for empirical evaluation and rigorous research. Therefore, Modern political economy in US is profoundly rooted in the social sciences' stan-dard approach, which, distilled to its bare bones, literally means making a claim and checking it against empirical facts.
In UK, academics are more open to ties with other academic disciplines beyond the mainstream economics and political science than in the US; they also display a greater interest in normative issues
the US favors liberty—the freedom of expression, which includes financial donations—while the UK favors equality. “Most European elections, and the UK is an example of this, are based on the principle of equality, of trying to ensure that the spending does not unduly advantage one side or another".
The United States has a written constitution as does the vast majority of nation states. The UK does not have a single document called the constitution but instead its constitutional provisions are written in many different places like statues, court judgements and through EU law.
The British political system has no such formal separation of the powers - indeed one person is actually a member of all three arms of government, since the Lord Chancellor is a member of the Cabinet (the executive), a member of the House of Commons of the House of Lords (the legislature) and the head of the legal system (the judiciary).
In the United States, because of the separation of the powers, no Cabinet member is allowed to be a member of the Congress. In Britain, every Government Minister must be a member of one of the two Houses of Parliament and, if he or she is not already in the Parliament, then he or she is made a member of the House of Lords.
