Book Description
The New Keynesian Phillips Curve is at the center of two raging empirical debates. First, how can purely forward looking pricing account for the observed persistence in aggregate inflation. Second, price-setting responds to movements in marginal costs, which should therefore be the driving force to observed inflation dynamics. This is not always the case in typical estimations. In this paper, we show how heterogeneity in pricing behavior is relevant to both questions. We detail the conditions under which imposing homogeneity results in overestimating a backward-looking component in (aggregate) inflation, and under estimating the importance of (aggregate) marginal costs for (aggregate) inflation. We provide intuition for the direction of these biases, and verify them in French data with information on prices and marginal costs at the industry level. We show that the apparent discrepancy in the estimated duration of nominal rigidities, as implied from aggregate or microeconomic data, can be fully attributable to a heterogeneity bias.

Book Description
Empirical tests of the New Keynesian Phillips Curve have provided results often inconsistent with microeconomic evidence. To overcome the pitfalls of standard estimations on aggregate data, a Full Information Partial Equilibrium approach is developed to exploit sectoral level data. A model featuring sectoral NKPCs subject to a rich set of shocks is constructed. Necessary and sufficient conditions on the structural parameters are provided to allow sectoral idiosyncratic components to be linearly extracted. Estimation biases are corrected using the model's restrictions on the partial equilibrium propagation of idiosyncratic shocks. An application to the US, Japan and the UK rejects the purely forward looking, labor cost-based NKPC.

Book Description
Most empirical work on the U.S. Phillips curve has had a strong tendency to impose global linearity on the data. The basic objective of this paper is to reconsider the issue of nonlinearity and to underscore its importance for policymaking. After briefly reviewing the history of the Phillips curve and the basis for convexity, we derive it explicitly using standard models of wage and price determination. We provide some empirical estimates of Phillips curves and Phillips lines for the United States and use some illustrative simulations to contrast the policy implications of the two models.

Book Description
Seminar paper from the year 2007 in the subject Economics - Economic Cycle and Growth, grade: 1,0, University of applied sciences Frankfurt a. M., course: Inflation and the Phillips Curve, language: English, abstract: In this paper the author will discuss the relation of inflation and the Phillips curve. First, the concept and the different forms of inflation and their economical reasons will be explained. Afterwards the three prevalent models of the Phillips curve in literature are introduced and explained. The author will look into the theory of the NRU and NAIRU and how they relate to the concept of the Phillips curve. In the last part of the paper, the applicability and validity of the Phillips curve for Germany is investigated more closely and the characteristics of the Phillips curve for Germany will be described. The Phillips curve originates of an empirical study of Arthur W. Phillips in 1958. There he describes the existence of a negative relationship between the rate of unemployment and the nominal wage growth in the UK between the years 1861-1957. The curve shows, that the higher the rate of unemployment, the lower the rate of wage inflation. His work represented a milestone in the development of macroeconomics. Especially in the sixties and seventies, politicians in the USA and Europe thought they can interpret the relation of inflation and unemployment as a menu card of fiscal and monetary policy. A well-known quote by Helmut Schmidt, former chancellor of Germany in the 1970s, supports this thinking, when he said that an inflation rate of five percent is better than a five percent rate of unemployment. In the following years, a lot of different economist (Keynes, Samuelson, Friedman, Phelps, Lipsey et al.) modified the original curve and supported it with their customized theories. In this paper the author will discuss the relation of inflation and the Phillips curve. First, the concept and the different forms of inflation and their economical reasons will be explained. Afterwards the three prevalent models of the Phillips curve in literature are introduced and explained. The author will look into the theory of the NRU and NAIRU and how they relate to the concept of the Phillips curve. In the last part of the paper, the applicability and validity of the Phillips curve for Germany is investigated more closely and the characteristics of the Phillips curve for Germany will be described.

Book Description
This book reconsiders the role of the Phillips curve in macroeconomic analysis in the first twenty years following the famous work by A. W. H. Phillips, after whom it is named. It argues that the story conventionally told is entirely misleading. In that story, Phillips made a great breakthrough but his work led to a view that inflationary policy could be used systematically to maintain low unemployment, and that it was only after the work of Milton Friedman and Edmund Phelps about a decade after Phillips' that this view was rejected. On the contrary, a detailed analysis of the literature of the times shows that the idea of a negative relation between wage change and unemployment - supposedly Phillips' discovery - was commonplace in the 1950s, as were the arguments attributed to Friedman and Phelps by the conventional story. And, perhaps most importantly, there is scarcely any sign of the idea of the inflation-unemployment tradeoff promoting inflationary policy, either in the theoretical literature or in actual policymaking. The book demonstrates and identifies a number of main strands of the actual thinking of the 1950s, 1960s, and 1970s on the question of the determination of inflation and its relation to other variables. The result is not only a rejection of the Phillips curve story as it has been told, and a reassessment of the understanding of the economists of those years of macroeconomics, but also the construction of an alternative, and historically more authentic account, of the economic theory of those times. A notable outcome is that the economic theory of the time was not nearly so naive as it has been portrayed.

Book Description
We study the global inflation surge during the pandemic recovery and the implications for aggregate and sectoral Phillips curves. We provide evidence that Phillips curves shifted up and steepened across advanced economies, and that differences in the inflation response across sectors imply the relative price of goods has been pro-cyclical this time around rather than a-cyclical as during previous cycles. We show analytically that these three features emerge endogenously in a two-sector new-Keynesian model when we introduce unbalanced recoveries that run against a supply constraint in the goods sector. A calibrated exercise shows that the resulting changes to the output-inflation relation are quantitatively important and improve the model's ability to replicate the inflation surge during this period.
