Smithian growth model from Michael Joffe Fig. 3.7 p57 Ch3 Feedback Economics Book

Implementation of the Solow model of economic growth with labor enhancing technology.

parameters: s, alpha, delta, n, gA
variables: Y. K, L, C, A
per capita variables: y, k, c, a
per capita and technology variables: y~, k~, c~
steady state variables: y~*, k~*, c~*
all variables come with relative growth rates g

Features:

+steady state from beginning
+one time labor shock
+permanent savings quote shock
+permanent technological growth rate shock

Decreasing steady state variables when starting in steady state are numeric artifacts.

This Model described the outbreak simulation under government policy and impacts on Economics.

This model demonstrate how the exisitng tested COVID cases effects economic recovery via goverment intervenes.

To develop a model and rating system to be able assess how sustainably responsible the Queensland Government, Local Government, Government Agencies, and Industry are. The rating system is based on the key sustainability factors identified by the United Nations: Social, Environment, and Economic.

Ocean/atmosphere/biosphere model tuned for interactive economics-based simulations from Y2k on.

This model shows the operation of a simple economy. It demonstrates the effect of changes in the fractional rate of consumption (or the converse, the fractional rate of saving.) It also, unlike Models 2 & 3, shows the influence Savings has on the production rate.

In summary, lower rates of consumption (based on production) result in higher rates of both production and consumption in the long-run.

This model shows the operation of a simple economy with two modifications made to Model 2 -- 1) feedback from production rate to consumption rate and 2) the use of a fractional rate input for calculating consumption rate. 

In summary, lower fractional rates of consumption (based on production) result in higher levels of Savings.

The recent moratorium on deep-sea drilling will reduce the supply of oil. But the world-wide trend is an ever increasing demand for it. This simple CLD  tries to illustrate the dampening effect on demand and on economic activity of diminishing oil supplies and of rising prices: oil prices  affect virtually all products and especially agricultural production. As it becomes more and more difficult to extract oil, prices must rise. At the moment the global recession counteracts this effect, but the recession will not last forever. Is it too early to speak of Peak Oil?

A sample model for class discussion modeling COVID-19 outbreaks and responses from government with the effect on the local economy.  Govt policy is dependent on reported COVID-19 cases, which in turn depend on testing rates less those who recover

A simple implementation of a Dynamic ISLM model as proposed by Blanchard (1981), and taken from An introduction to economic Dynamics - Shone (1997) - chapter 5. This model might serve as a framework to evaluate economic policies over GDP growth.

Summary WIP of Thomas Palley's 2012 Book

This high-level simulation model presented by Jay Forrester in his book World Dynamics, simulates socio-economic-environmental world system. The world Model was created in a time where pollution and other negative effects of industrialization and economic growth started to become recognized in 1970. For this exam purpose, we have rebuilt the model to do some experiments and analyze the results.

De Innovadores a Imitadores

New Product Adoption Dynamics models how an innovation spreads through a population via two main drivers:

• Innovator probability, which determines how many people adopt the product independently and autonomously.

• Imitator conversion rate, which measures how many new adopters join due to social contact and word of mouth (WOM).

This approach helps us understand how the total flow of new adopters evolves over time.

📈 Applied example: In the adoption of renewable energy, early users (innovators) install solar panels out of conviction or future-oriented vision. Later, their visible results and testimonials create an imitation effect among neighbors, accelerating broader adoption. This model helps predict how much diffusion can be achieved through different promotional strategies or public policies.
