Research contributions

A major theme of Orphanides’ research on monetary economics has been the evaluation and design of monetary policy in real time. He argued that since the data available to policy makers at the time policy decisions are made are imperfect and subject to substantial revisions, the historical analysis of monetary policy decisions as well as the evaluation of alternative policy strategies must be based on the information available in real time (Orphanides, 2001, Orphanides, 2003). His work has documented significant problems arising from policy decisions drawing on unobservable concepts such as the output gap. Orphanides has argued against output-gap-based policy rules, such as the Taylor rule
Taylor rule
In economics, a Taylor rule is a monetary-policy rule that stipulates how much the central bank should change the nominal interest rate in response to changes in inflation, output, or other economic conditions. In particular, the rule stipulates that for each one-percent increase in inflation, the...

 or optimal control policy, is counterproductive for stabilizing the macroeconomy. He has also provided an explanation of the high inflation experience in the United States during the late 1960s and 1970s as resulting from policy focused too closely at stabilizing the real economy, by aiming to close the perceived output and unemployment gaps. According to this analysis, the high inflation resulted from the fact these gaps were badly mismeasured due to overoptimistic real time estimates of potential output and the natural rate of unemployment (Orphanides, 2003).

In related work, Orphanides and Simon van Norden, have explained that the unreliability of output gap measures in real time is of a more general nature than previously thought. They documented the unreliability of various statistical techniques for measuring the output gap

estimates for forecasting inflation, thus calling into question policy approaches that rely on the output for stabilization policy (Orphanides and Norden, 2002).

The role of imperfect knowledge and the formation of expectations in a learning environment has been a theme in the work by Orphanides and John C. Williams. They have argued that the central bank must ensure that inflation expectations must remain well-anchored, in line with the central bank’s price stability objective, in order to improve the stability of the macroeconomy. Their work documented the benefits associated with a central bank’s numerical price stability objective and the pitfalls of optimal control policy design (Orphanides and Williams, 2008).

Working with Volker Wieland and others, Orphanides also contributed to research on the conduct of monetary policy near to zero lower bound for nominal interest rates. This work was motivated by the Japanese experience with near-zero rates in the late 1990s but became of immediate policy relevance during the 2008 global financial crisis (Orphanides and Wieland, 2000).
