Expanding the 2x2: Beyond Public and Private image

Talking about how the dichotomy in the public goods debate is actually a false dichotomy with no clear boundaries

The classic 2x2 classification of goods, pioneered by Paul Samuelson and extended by Vincent and Elinor Ostrom … It assumes two classifications: excludability (can an individual be prevented from consuming it) and competitiveness (does consumption by one individual reduce the opportunities available to other individuals). … Most resources go from private to public. Even private goods may be shared with family and friends or have small positive externalities (e.g., furniture in a communal house). Most public goods (i.e. goods or services such as parks or highways) are semi-excludable due to geographic conditions or access (e.g. lighthouses, fire stations, parks). These, along with most club goods, are also semi-competitive through depletion, congestion, and exhaustion (e.g., roads, trails, library books, golf courses). A more realistic concept would be to imagine contestability and excludability not as discrete measures, but as continuous measures.
