The Lucas critique: A Lucas critique. Econometric policy evaluation: A critique. That is, the Lucas critique has had a tremendous impact on macroeconomic theory and policy analysis. To give credit to Lucas (1976), the next section aims partly to give a review of this important contribution, and partly to point out some of the consequences that the Lucas critique had on the development of macroeconomics.

The Lucas critique has been – and continues to be – the cornerstone of modern macroeconomic modelling. Put simply, unless you model the macro economy as a result of ‘deep parameters’ of the human psyche, you will never be sure whether your model will apply in a different regulatory or institutional environment. In the early 1970s, Robert E. Lucas Jr, developed an alternative theory of the Phillips curve and the money-driven business cycle, under the assumption of rational expectations. The critique is fundamental to modern macroeconomics, where statistical relationships across a number of economic variables are analysed and used to make policy-decisions, however the effectiveness and predictability of such methods is notoriously difficult to ascertain.

The classical example of the Lucas critique is inflation expectations. 1. The Lucas Critique, named after economist Robert Lucas, is a theoretical result that blew up the discipline of macroeconomics in the 1970s, and its implications are directly relevant to much of the work that data scientists are doing today—including work that I am doing on the Algorithms team at Wayfair!

What’s at stake: there has been a new round of discussions on the blogosphere about micro foundations in macroeconomics following a recent speech by Charles Plosser – President of the Philadelphia Fed and one of the founders of the Real Business Cycle theory – where he argued that the Lucas critique has become more as […] Thus, a policy that worked under one set of circumstances may not apply under a different set.

Taylor, May 6, 2013. Modern DSGE models are microfounded and have deep parameters that should be invariant to changes in economic policy, so in principle they are not subject to the Lucas critique. This contribution to the history of the economic thought aims at describing how “Econometric Policy Evaluation: A Critique” (Lucas, 1976) has been interpreted through four decades of debates. The critique is fundamental to modern macroeconomics, where statistical relationships across a number of economic variables are analysed and used to make policy-decisions, however the effectiveness and predictability of such methods is notoriously difficult to ascertain. Lucas, of course, received the Nobel prize in economics in 1995 and is, among other distinctions, the originator of the eponymous "Lucas critique," which the Nobel committee described in this way: "The 'Lucas critique' - Lucas's contribution to macroeconometric evaluation of economic policy - has received enormous attention and been completely incorporated in current thought.

Super exogeneity is always potentially refutable, and when both implications are involved, the Lucas critique is also refutable. The costs of re-optimizing every time you face something new don’t always offset the benefits from making what may be only a slightly better choice. Though a great deal of ink has been spilled since the 1970s penning complicated, mathematical treatments of the Lucas Critique, its core claim is elegant in its simplicity: Now let us unpack the five key terms in that core claim: model, policy, policy variable, policy rule, and optimal.

If monetary policy changes to become much harder on inflation, then rational agents will incorporate that into the way they form inflation expectations. Lucas (1976) considers examples where agents’ expectations of policy behavior enter into their optimization problem, and so parameters relating to policymakers’ rules appear in the agents’ first-order conditions.
