He has four brothers and two sisters. One of his brothers, Chris Romeris a former Colorado state senator. He was named one of America's 25 most influential people by Time magazine in and he was awarded the Horst Claus Recktenwald Prize in Economics in Academia[ edit ] Romer's research on economic growth followed extensive studies of long-run growth during the s and s.
Emerging in its place is the Taylor—Romer TR model of macroeconomic stabilisation, in which the central bank adopts an interest rate rule. This article argues that the goals of realism and simplicity can be further advanced with some refinement of the TR model. Several minor modifications are advocated.
One is the explicit recognition that inflation can be too low witness Japan as well as too high. Another is the replacement of output with the growth rate of output. An additional Romer model is proposed to the diagram so as to reflect better the actual adjustment paths that are likely to be observed following demand and supply shocks.
This paper also shows how these adjustment paths can be easily simulated by students using standard spreadsheet software.
A22 Introduction All is not well with the teaching of undergraduate economics. Too many students graduate with a lack of understanding of some basic concepts and have a relatively low opinion of the quality of the teaching that they have received. This is the consistent message from numerous studies over the past 20 years see, for example, Hartman, ; Colander and Klamer, ; Becker, ; Walstad and Allgood, ; Becker and Watts, ; Guest and Duhs, Several pedagogic problems have been identified concerning content, teaching approaches and assessment.
In particular, first-year courses tend to have too much content and are over-concerned with theory at the expense of real-world application Guest and Duhs, ; Colander, ; Heyne, ; Siegfried et al.
The latter criticism arises from the trade-off that often exists between realism and simplicity in presenting economic models to students. It is hard to win — our models are criticised for being unrealistic, but when we add realism the model becomes too complex.
Better pedagogy in economics requires, among other things, more realistic models that are not more complex. There are two main problems with the model as a tool for teaching macroeconomic stabilisation policy.
One is that nowadays almost all central banks of industrialised countries adopt an interest rate target in the short run Romer,p. This renders the LM curve horizontal at the real interest rate target.
As a teaching tool, therefore, the LM curve is redundant. It is not necessary to show how equilibrium between money demand and money supply imply an LM curve if the LM curve is always horizontal.
It is simpler to draw a horizontal line at the real interest rate and call it something else. Taylorcalls it the IA line. The second pedagogic problem with the traditional model is that, in AD-AS space, the price level rather than the inflation rate is on the vertical axis.
This leaves teachers with the tortuous process of explaining to students that a fall in aggregate demand does not really imply a fall in the price level, unless inflation is zero, which it almost never is. It just means a fall in the price level below what it would otherwise have been.
To depict inflation on the diagram, one must draw AD and AS curves disappearing off the top of the page. Then, to capture contractionary AD policy in an inflationary environment requires a ludicrously complicated diagram for such a simple idea.
It is inflation, not the price level, that is a long-run target variable of most central banks.
Hence an improvement in both realism and simplicity is to show the inflation rate on the vertical axis, which both Taylorand Romer do. We will call the alternative model that these authors have developed the Taylor—Romer TR model. The remainder of the paper is organised as follows.
The next section outlines the TR model, while the third section discusses some minor shortcomings of the model, mainly in terms of its diagrammatic representation.Teaching Undergraduate Macroeconomics with the Taylor-Romer Model Paul Turner, * [email protected] * Dr Paul Turner, Department of Economics, Loughborough University, Loughborough, LE11 3TU UK Abstract This paper sets out a version of the Taylor-Romer model of short-run macroeconomic equilibrium which can be used for teaching undergraduate economics principles .
