Non-neutrality of economic policy: An application of the Tinbergen-Theil’s approach to a strategic context

Issues of policy effectiveness and neutrality are widespread in the economic literature. They have been increasingly raised in specific contexts within the class of LQ (linear-quadratic) policy games in the last 20 years, notably with reference to monetary policy. The more general conditions ensuring nonneutrality in a strategic environment remain however to be inquired. We fill this gap by applying the classical theory of economic policy to a strategic context. This is also useful to highlight some existence conditions for policy game solutions. We restrict ourselves to the common LQ-games in a static perfect information framework, but our simple logic can be extended to other more general situations.
