overall_score: 4.2
scores:
- name: definition_precision
  value: 4.0
  max_value: 5.0
  rationale: The definition clearly identifies coal price as a market price influenced
    by specific factors (abundance, transportation costs, alternative fuels availability).
    It avoids circularity and captures a distinct economic concept with measurable
    characteristics.
- name: source_grounding
  value: 5.0
  max_value: 5.0
  rationale: This entity is well-grounded in Smith's actual analysis from Book I,
    Chapter 11, where he specifically examines coal prices as an example of how natural
    resource abundance affects rent components in commodity pricing. The context accurately
    reflects Smith's comparative analysis of coal versus agricultural land rents.
- name: domain_placement
  value: 5.0
  max_value: 5.0
  rationale: The "Production" domain assignment is correct, as coal price directly
    relates to the costs and economics of productive processes. Coal serves as both
    an input to production and a commodity whose pricing Smith analyzes within his
    broader production theory.
- name: vsm_relevance
  value: 3.0
  max_value: 5.0
  rationale: Coal price has moderate VSM relevance, primarily mapping to S1 (operational
    costs affecting primary production activities) and potentially S4 (environmental
    intelligence about resource markets). However, it's more of an operational parameter
    than a core VSM structural element.
- name: explanatory_value
  value: 4.0
  max_value: 5.0
  rationale: This entity provides good explanatory value by illustrating Smith's mechanism
    of how natural resource abundance affects rent structures and commodity pricing.
    It demonstrates a concrete application of his theoretical framework about the
    relationship between scarcity, location, and economic rent.

# Evaluation: Coal Price

## definition_precision — 4.0 / 5.0

The definition clearly identifies coal price as a market price influenced by specific factors (abundance, transportation costs, alternative fuels availability). It avoids circularity and captures a distinct economic concept with measurable characteristics.

## source_grounding — 5.0 / 5.0

This entity is well-grounded in Smith's actual analysis from Book I, Chapter 11, where he specifically examines coal prices as an example of how natural resource abundance affects rent components in commodity pricing. The context accurately reflects Smith's comparative analysis of coal versus agricultural land rents.

## domain_placement — 5.0 / 5.0

The "Production" domain assignment is correct, as coal price directly relates to the costs and economics of productive processes. Coal serves as both an input to production and a commodity whose pricing Smith analyzes within his broader production theory.

## vsm_relevance — 3.0 / 5.0

Coal price has moderate VSM relevance, primarily mapping to S1 (operational costs affecting primary production activities) and potentially S4 (environmental intelligence about resource markets). However, it's more of an operational parameter than a core VSM structural element.

## explanatory_value — 4.0 / 5.0

This entity provides good explanatory value by illustrating Smith's mechanism of how natural resource abundance affects rent structures and commodity pricing. It demonstrates a concrete application of his theoretical framework about the relationship between scarcity, location, and economic rent.
