The paper shows how aggregate AS-AD can be derived within the standard neoclassical dynamic setting known as the Ramsey-Cass- Koopmans (RCK) model. AS-AD is the stationary equilibrium of the deterministic dynamic general equilibrium framework. The derivation builds a permanent income type...

We extend upon Reeves (2020), who attempts to demonstrate that classical violations of the Law of Demand are in actuality the result of a violation of the ‘ceteris paribus’ assumption. For example, price changes in Giffen goods create a chain reaction from the Giffen good through a...

Diminishing marginal utility is neither necessary nor sufficient for downward sloping demand, and it is not necessary for convex indifference curves. We illustrate these facts with two simple counter examples, using valid and easy to understand utility functions. The examples are accompanied...

Purpose The purpose of this paper is to contribute to the teaching of undergraduate macroeconomics. Design/methodology/approach To suggest a roadmap, based on a consumption function, to be used by instructors willing to teach the Lucas Critique subject. Findings Therefore, this paper proposes a...

Collective consumption decisions taken by the members of a household may prove inefficient. The impact of such inefficient household decisions on market performance is investigated. At one extreme, market efficiency can occur even when household decisions are inefficient, namely when household...

Risk may induce precautionary saving but it can also reduce saving. The theoretical literature recognizes both possibilities, but favors a positive effect (both for developed and developing countries); the empirical literature is divided, reporting (small) positive effects for developed...

This paper investigates empirically why Japan's household savings rate fell in the 1990s. We constructed an economic model consisting of two types of household: unconstrained life-cycle households and liquidity-constrained households. Unconstrained households generally save, but...

In an overlapping generations maximization framework with consumers, whose information on uncertain future income realizations is front loaded, a closed form aggregate consumption function with CRRA preferences is derived. To have a closed form solution we assume that consumers solve their...
