Introduction to Agent-Based Stock-Flow Consistent Modelling

How countries achieve long-term GDP growth is up there with the most important topics in economics. As Nobel Laureate Robert Lucas put it “the consequences for human welfare involved in questions like these are simply staggering: once one starts to think about them, it is hard to think about anything else.” Ricardo Hausmann et al take a refreshing approach to this question in their Atlas of Economic Complexity. They argue a country’s growth depends on the complexity of its economy: it must have a diverse economy which produces a wide variety of products, including ones that cannot be produced much elsewhere. The Atlas goes into detail on exactly what complexity means, how it fits the data, and what this implies for development. Below I will offer a summary of their arguments, including some cool data visualisations.

This short video by the Khan Academy presents a classic introduction to economic teaching. Starting with the quote by Adam Smith in "The Wealth of Nations" on the invisible hand, it shows how economics deals with the question of the allocation of scarce resources and shortly presents different questions addressed by microeconomics and macroeconomics. It further makes reference to questions of simplification in mathematical models.

Ziel dieser kritischen Einführung in die Volkswirtschaft ist es, auf knappem Raum unterschiedliche Sichtweisen auf wirtschaftliche Zusammenhänge darzulegen und damit die Basis für ein differenziertes Verständnis von Ökonomie und wirtschaftspolitischen Debatten zu liefern. In Zeiten einer integrierten Weltwirtschaft, rascher Veränderungen und internationaler Krisen liegt es nahe, Wirtschaft in ihrer internationalen Dimension in den Mittelpunkt zu stellen, anstatt wie gehabt meist nationale Ökonomien isoliert zu betrachten. Miteinander asymmetrisch verbundene Entwicklungen und Veränderungen in Nord und Süd, die auf globaler sowie zwischen nationaler und regionaler Ebene stattfinden, stellen somit einen zentralen Bezugspunkt dar. Daher der Titel des Buches: Ökonomie und internationale Entwicklung.

In this blog article Steve Keen elaborates on flawed climate change modelling and mainstream economics forecasts. In specific, he stresses the climate change forecasts of the DICE model (“Dynamic Integrated model of Climate and the Economy”) by Nobel Memorial Prize in Economic Sciences winner William Nordhaus.
