From Policy Concepts in 1000 Words: Policy Transfer and Learning

‘Policy learning’ describes the use of knowledge to inform policy decisions. That knowledge can be based on information regarding the current problem, lessons from the past or lessons from the experience of others. This is a political, not technical or objective, process (for example, see the ACF post). ‘Policy transfer’ describes the transfer of policy solutions or ideas from one place to another, such as by one government importing the policy in another country (note related terms such as ‘lesson-drawing’, ‘policy diffusion’ and ‘policy convergence’ – transfer is a catch-all, umbrella, term). Although these terms can be very closely related (one would hope that a government learns from the experiences of another before transferring policy) they can also operate relatively independently. For example, a government may decide not to transfer policy after learning from the experience of another, or it may transfer (or ‘emulate’) without really understanding why the exporting country had a successful experience (see the post on bounded rationality).

The descriptive/ empirical side asks these sorts of questions:

From where are lessons drawn? In the US, the diffusion literature examines which states tend to innovate or emulate. Some countries are also known as innovators in certain fields – such as Sweden and the social democratic state, Germany on inflation control and the UK on privatization. The US (or its states) tends to be a major exporter of ideas. Some countries often learn consistently from the same source (such as the UK from the US). Studies tend to highlight the reasons for borrowing from certain countries – for example, they share an ideology, common problems or policy conditions. ‘Globalization’ has also reduced practical barriers to learning between countries.

Who is involved? Apart from the usual suspects (elected officials, civil servants, interest groups), we can identify the role of federal governments (for states), international organizations (for countries), ‘policy entrepreneurs’ (who use their experience in one country to sell that policy to another – such as the Harvard Business School professor travelling the world selling ‘new public management’), international networks of experts (who feed up ideas to their national governments), multinational corporations (who encourage the ‘race to the bottom’, or the reduction of taxes and regulations in many countries), and other countries (such as the US).
