We re-assess Blanchard-Kiyotaki (1987). We conclude that there are multiple equilibria even under the flexible-price Blanchard-Kiyotaki model, and that the model only obtains equilibrium uniqueness through the symmetry condition that is partially justified only when there are infinitely many...

We argue that the paradox of flexibility - that more flexible price results in worse outcomes when zero lower bound is binding - is ruled out once we consider an implicit equilibrium selection mechanism used when solving a New Keynesian model often not explicitly stated - the symmetric limit...

A common question against macroeconomics of public debts is: why should one think government budget constraint is binding when government, at least technically, can print out money to pay for debts. Out of compatible answers, we explore an answer that is not usually invoked. While in OLG models,...

A theory of the firm based on the idea that firms are problem solvers is developed. A network of firms and hierarchical structure of an individual firm are analyzed in terms of distributed and parallel computing. This framework, based on notions of computer science, allows us a simple answer to...

This paper intends to discuss some problematic properties IS-LM and loanable funds together have when dealing with fiscal deficits. Many others have focused on its assumptions for criticism of IS-LM, but I will mainly focus on its fundamental modelling nature. To say more specifically, I will...

In this paper, several flaws of the basic no-capital/labor-only New Keynesian model are discussed. Some flaws were left undiscovered because mass of varieties n in Dixit-Stiglitz aggregator is often considered as not affecting overall outcomes. Only when n=1 would ordinary results of the basic...

This paper explores dimensional analysis of production and utility functions in economics. As raised by Barnett, dimensional analysis is important in consistency checks of economics functions. However, unlike Barnett's dismissal of CES and Cobb-Douglas production functions, we will demonstrate...

The very fact that utility maximization in real business cycle and New Keynesian models is intertemporal suggests the possibility of a Fisherian intertemporal futures market, which is not state-contingent. Ex-ante speaking, the addition of a futures market does not result in any difference, but...
