The celebrated ecological economist Herman Daly asked: "Is there not a negl
ected connection between the environment and the macroeonomics we teach? If
there is no such thing as environmental macroeconomics in our textbooks, s
hould there be? If so, what would it look like?" [Daly, H., 1991. Towards a
n environmental macroeconomics. Land Econ. 67(2), 255-259]. Emphasising the
need to breach widely-used undergraduate texts - such as Abel and Bernanke
[Abel, A., Bernanke, B.S., 1998. Macroeconomics, 3rd edition. Addison-Wesl
ey, New York], Begg et al. [Begg, D., Fischer, S., Dornbusch: R., 1998. Eco
nomics 5th edition. McGraw-Hill, London] and Sloman [Sloman, J., 1997. Econ
omics, 3rd edition, Prentice-Hall, London] - we show that an 'environmental
equilibrium' (EE) line can be added to the standard IS-LM diagram which re
mains the workhorse of undergraduate macro teaching and is widely used for
applied policy analysis. The familiar comparative static analysis of fiscal
and monetary policy are reworked. It is argued that chapter sections detai
ling the environmental extension should be incorporated into all IS-LM-usin
g texts. (C) 2000 Elsevier Science B.V. All rights reserved.
