Investment depends on subjective factors, such as expectations, conventions,
and confident animal spirits. In a context of economic instability and
crises, economic policy is the main source to support entrepreneurs?
expectations and investment. In this sense, macroeconomic policies are
capable of affecting effective demand and building a good institutional
environment, which is essential to keep the entrepreneurs? expectations
confident and promote their animal spirits. Given these propositions, this
contribution has two objectives. The first is to develop a Keynesian type of
macroeconomic policy able to stimulate investment and effective demand, and,
as a result, mitigate unemployment. The idea is to offer alternative
macroeconomic policy prescriptions in relation to the New Consensus
Macroeconomics one. This proposal aims to establish the role, according to
the Post Keynesian view, the logic of operation of each policy, and the
proper coordination among these Keynesian macroeconomic policies. The second
objective is to present, briefly, relevant empirical evidence of the Post
Keynesian macroeconomic policies.
