It is shown that, in pure exchange economies, the individual demand functions can be recovered from the equilibrium set regardless of the way we evaluate wealth. Following Balasco (2004), the demand functions do not have to be differentiable, not even continuous nor utility maximizing. Thus, the...

This paper utilizes the baseline Real Business Cycle (RBC) model in order to construct a time recursive approximate optimal decision rule as a linear function of the model's state variables and an exogenous surprise shock that hits the economy. The constructed rule is subsequently used in order...

The authors consider a multivariable system comprising a set of macroeconomic variables as inputs, states and outputs. In this setting the authors assess the control potential of fiscal policy versus a large negative business cycle shock that affects the output of the system. The inputs...

A linear control system in the form of a vector autoregressive (VAR) model with an input is considered. The system comprises a set of macroeconomic variables as inputs, states and outputs. The state variables included are the cyclical components of gross domestic product (GDP) and the rate of...

In a simple model based on political support approach, we show that poor and less egalitarian societies may impose a lower tax rate contrary to the prediction of the median voter approach. This is consistent with the available empirical findings. In the framework developed in this paper, the...
