The Rationality of Contribution
A small town is considering building a public park. The project requires voluntary donations from its 100 residents. The park will be built if at least $10,000 is collected, and once built, all residents can use it for free, regardless of whether they donated. An individual resident is deciding whether to donate $100. From the perspective of a purely rational and self-interested individual focused only on their own personal gain, explain the most logical course of action and the reasoning behind it.

The Adequacy of the Homo Economicus Assumption
Edgeworth on Self-Interest as the First Principle of Economics
Two competing businesses, A and B, are located on the same river, which is their only source of water for production. Each business must decide independently whether to install an expensive water filtration system that recycles water, reducing their draw from the river. If both businesses install the system, the river remains healthy, and both can operate indefinitely. If only one installs it, the river's water level drops, but both can still operate, though the one who didn't install the system has a significant cost advantage. If neither installs the system, the river will be depleted within a year, forcing both businesses to shut down. Assuming both business owners behave as perfectly rational, calculating, and self-interested agents focused solely on maximizing their own individual profit, what is the most likely outcome?

Evaluating the 'Economic Man' Assumption
In a one-time interaction, Person A is given $100 and must offer a portion of it to Person B. Person B can either accept the offer, in which case they both keep the proposed amounts, or reject it, in which case neither person receives any money. Assuming both individuals behave as perfectly rational, calculating agents focused solely on maximizing their own personal gain, which of the following outcomes is most likely?
Evaluating the 'Economic Man' Assumption
The model of 'economic man' (homo economicus) assumes that an individual's decisions are primarily driven by a desire for personal gain, but can also be influenced by feelings of fairness or a sense of duty to their community.
