If somebody want to know what happens with austerity policies, then this is the book to read.
The term “austerity” indicates a policy of sizeable reduction of government
deficits and stabilization of government debt achieved by means
of spending cuts or tax increases, or both. This book examines the costs
of austerity in terms of lost output, what types of austerity policies can
achieve the stated goals at the lowest costs, and the electoral effects for
governments implementing these policies.
Why Austerity?
If governments followed adequate fiscal policies most of the time, we
would almost never need austerity. Economic theory and good practice
suggest that a government should run deficits during recessions—when
tax revenues are low and government spending is high as a result of
the working of fiscal stabilizers such as unemployment subsidies—and
during periods of temporarily high spending needs, say because of a natural
calamity or a war.
