Why is Economics not a Complex Systems Science?
Foster, John - 2004
Economics is viewed as a discipline that is mainly concerned with 'simplistic' theorizing, centered upon constrained optimization. As such, it is ahistorical and outcome focused, ie, it does not deal with economic processes. It is argued that all parts of the economy are inhabited by complex...

A structural model of coronavirus behaviour for testing on data behaviour
Meenagh, David; Minford, Patrick - 2021
We fit the logistic function, the reduced form of epidemic behaviour, to the data for deaths from Covid-19, for a wide variety of countries, with a view to estimating a causal model of the covid virus' progression. We then set out a structural model of the Covid virus behaviour based on...

Simultaneity of green energy and hydrogen production: Analysing the dispatch of a grid-connected electrolyser
Schlund, David; Theile, Philipp - 2021
Hydrogen is viewed as a promising supplement in future energy systems with high penetration rates of renewable energy (RE) generation. As conversion technology between the two secondary energy carriers, hydrogen and electricity, particularly grid-connected electrolysers, have a role to play....

Striking evidence: The impact of railway strikes on competition from intercity bus services in Germany
Beestermöller, Matthias Gerhard; Jessen-Thiesen, Levke; … - 2023
This paper investigates the impact of the largest rail strikes in German history on intercity buses - a then newly liberalised market. Using unique booking data of bus services, we exploit variation in rail service cancellations across routes to show that the disruption in rail transport...
