The section provides a detailed numerical and analytical discussion of the model, including how to construct balance sheet and transaction flow matrices, and a simple recipe for building SFC models. (5/5)

It shows how changes in aggregate demand drive credit and money creation, and how shifts in liquidity preference can impact bond markets. (4/5)

The model illuminates the process by which economic production is financed, incorporating the ideas of endogenous money creation and price determination in financial markets. (3/5)

The section shows how to simulate in R / Python a stock-flow consistent model that captures key ideas of Augusto Graziani’s monetary circuit. The model is an extended version of Wynne Godley’s 2004 paper:

Weaving Cloth from Graziani’s Thread: Endogenous Money in a Simple (but Complete) Keynesian Model
One of Graziani’s main themes runs as follows. In order to finance production, the entrepreneur must obtain the funds necessary to pay his workforce in advance of sales taking place. Starting fr...

Despite its simplicity, the model captures key empirical patterns related to superstar firms and declining labour shares. (7/7)

These dynamics lead to right-skewed distributions, producing a divergence between the average profit share across firms and the aggregate profit share, which is driven up by the biggest firms. The fall in the labour share reduces consumption and slows down growth. (6/7)

At the same time, customers seek lower prices, creating competitive pressure. These mechanisms drive endogenous changes in the firm size distribution. More profitable firms temporarily grow faster, leading to concentration of capital, market shares, and markups. (5/7)
July 29, 2025 at 1:55 PM
The model captures how pricing, investment, and market concentration evolve at the micro level and affect macro-level outcomes. Firms differ in capital size and market share. Larger firms benefit from lower unit costs due to economies of scale, gain larger market shares, and charge higher markups. 4

... an ABM with bilateral firm-customer matching, and a simplified HAM without direct agent interaction. The HAM replicates key ABM results while allowing for analytical solutions. (3/7)

The paper presents a small-scale analytical heterogeneous agent model (HAM) to explore firm concentration dynamics and the aggregate effects on distribution and growth. It contributes to recent work on tractable macroeconomic agent-based models (ABMs) by comparing two versions of the model: ... (2)

We find that low capital gains taxes and strong
landlord-protection policies that may push households onto the property ladder are linked to more
intense house price booms and busts. (6/6)

In an empirical analysis for 23 OECD countries, the paper
explores the role of speculation-encouraging institutions, credit permissiveness, welfare state regimes
and macroeconomic policy as potential factors. (5/6)

Bringing Minskyan and behavioural theories of endogenous financial cycles
to CPE, this paper argues that the intensity of house price booms and busts is shaped by institutions
that encourage speculative behaviour. (4/6)
July 23, 2025 at 2:19 PM
This matters as cycles in house prices are large relative to their trend and the intensity of house price cycles
differs across countries. (3/6)

Since the Global Financial Crisis, there is a growing literature on the Comparative Political Economy
(CPE) of housing, but it has not systematically incorporated boom-bust cycles in house prices. (2/6)
