Free Online Library: Is the natural unemployment rate hypothesis valid for the United States


There is always unemployment, it is natural, and thus dubbed the Natural Rate of Unemployment, and is normally 3%-5% of the labor force, due to frictionally unemployed workers with skills readily available and are either between jobs or fresh out of the education system.

My initial forays into European unemployment were aimed at explaining the dynamic effects of shocks on the natural rate, and the role of institutions in shaping these effects. In work with Lawrence H. Summers, I focused on how, when wages were set in collective bargaining, shocks could have long lasting effects on the natural rate (the "hysteresis" hypothesis). In work with Peter A. Diamond, I explored the effects of shocks in models with explicit flows and individual bargaining. In work with Lawrence F. Katz, I developed simple models of the determination of the natural rate and the Phillips curve. This research was summarized in an NBER Reporter article in 1995.

It is consistent with the natural rate hypothesis for ..

Previous studies use a variety of increasingly advanced unit root tests to determine whether Blanchard and Summers (1986) hysteresis theory of unemployment or the classical 'natural' rate theory of Friedman (1968) and Phelps (1967, 1968) is most relevant for a given country. However these tests all specify a unit root under the null hypothesis against a stationary alternative, such as in the paper by Lee and Chang (2008), making the two theories of unemployment mutually exclusive over the sample period. This paper moves away from this dichotomy by allowing for switches between hysteresis and the natural rate theory using the recently developed test of Leybourne, Kim and Taylor (2007). We find that in countries like the United Kingdom, the natural rate theory is detected in the post-World War Two period of stabilisation: the time leading up to the seminal works of Friedman and Phelps. Hysteresis is found over the First World War and Great Depression periods, and in the period from the 1970s; a time characterised by rising trade union power. We also compute numerical measures of persistence using grid-bootstrap estimates of the autoregressive parameter, following Hansen (1999). (C) 2010 Elsevier B.V. All rights reserved.

The book would have been further enriched by a complementary retrospectiveby Milton Friedman, who named this enduring concept in acknowledgment ofits kinship to Knut Wicksell's natural rate of interest and whose seminaldefinition of the natural rate ("the level [of unemployment] that wouldbe ground out by the Walrasian system of general equilibrium equations...")is quoted in full no fewer than a half-dozen times.

The other three contributorsto Part 1 (James Tobin, Frank Hahn, and Huw Dixon) are decidedly unsympatheticto Friedman and Phelp's fundamentally classical slice of reality.
In addition to editing thebook and supplying the introductory chapter, Rod Cross asks, "Is the naturalrate hypothesis consistent with hysteresis?" His answer: "No." Hysteresis,a termed coined by nineteenth-century physicist James Ewing in the contextof electromagnetism, derives from systemic non-linearities and path dependencies.
