There was a time when we economists steered clear of politics. We viewed our job as describing how market economies work, when they fail, and how well-designed policies can enhance efficiency. We analyzed trade-offs between competing objectives (say, equity versus efficiency), and prescribed policies to meet desired economic outcomes, including redistribution. It was up to politicians to take our advice (or not), and to bureaucrats to implement it.

Then some of us became more ambitious. Frustrated by the reality that much of our advice went unheeded (so many free-market solutions still waiting to be taken up!), we turned our analytical toolkit on the behavior of politicians and bureaucrats themselves. We began to examine political behavior using the same conceptual framework that we use for consumer and producer decisions in a market economy. Politicians became income-maximizing suppliers of policy favors; citizens became rent-seeking lobbies and special interests; and political systems became marketplaces in which votes and political influence are traded for economic benefits.

…

But there was a deep paradox in all of this. The more we claimed to be explaining, the less room was left for improving matters. If politicians’ behavior is determined by the vested interests to which they are beholden, economists’ advocacy of policy reforms is bound to fall on deaf ears. The more complete our social science, the more irrelevant our policy analysis.

…

Political economy undoubtedly remains important. Without a clear understanding of who gains and who loses from the status quo, it is difficult to make sense of our existing policies. But an excessive focus on vested interests can easily divert us from the critical contribution that policy analysis and political entrepreneurship can make. The possibilities of economic change are limited not just by the realities of political power, but also by the poverty of our ideas.
