--- ENTITY: market extent ---

# Market Extent

## Definition

The geographical and economic reach of a market, determining the potential size of demand for goods and services. The extent of the market directly limits the degree to which division of labour can be developed, as a larger market provides greater opportunity for exchange and specialisation.

## Source Chapter

Book I, Chapter 3

## Context

The central thesis of the chapter, establishing that the division of labour is fundamentally constrained by how far goods can be exchanged. Smith argues that when markets are small, individuals cannot specialise fully because they cannot exchange their surplus production for other goods they need.

--- ENTITY: water-carriage ---

# Water-Carriage

## Definition

Transportation of goods by water using ships and boats, which significantly reduces the cost and increases the speed of moving commodities compared to land-carriage. Water-carriage enables a much broader market extent by making distant trade economically feasible.

## Source Chapter

Book I, Chapter 3

## Context

Smith uses water-carriage as a key example to demonstrate how transportation technology affects market extent. He contrasts the efficiency of ships (two hundred tons carried by six or eight men) with land transport (the same quantity requiring fifty waggons, a hundred men, and four hundred horses), showing how water-carriage opens up extensive markets.

## Economic Domain

---
--- ENTITY: land-carriage ---

# Land-Carriage

## Definition

Transportation of goods by land using waggons, carts, and pack animals. Land-carriage is significantly more expensive than water-carriage due to higher labour costs, animal maintenance, and wear and tear on vehicles, thus limiting market extent and the division of labour.

## Source Chapter

Book I, Chapter 3

## Context

Smith uses land-carriage as a comparative example to illustrate the limitations of market extent. He calculates that land-carriage requires the maintenance of a hundred men for three weeks and four hundred horses to move two hundred tons, making it economically prohibitive for many goods and restricting trade to items with high value relative to weight.

--- ENTITY: navigable rivers ---

# Navigable Rivers

## Definition

Rivers that can be used for the transportation of goods by boat or ship, serving as natural highways that connect inland areas to coastal markets. Navigable rivers extend the reach of water-carriage into the interior of countries, enabling the development of markets and division of labour in inland regions.

## Source Chapter

Book I, Chapter 3

## Context

Smith identifies navigable rivers as crucial infrastructure for economic development, noting that industry naturally begins to subdivide and improve itself along their banks. He uses examples like the Nile in Egypt and various rivers in China to show how inland navigation creates extensive markets that support specialisation.

# Sea-Coast Development

## Definition

The pattern of economic development that occurs first along coastlines where water-carriage provides access to the widest possible markets. Sea-coast regions historically develop industry, trade, and division of labour before inland areas due to their superior access to extensive markets.

## Source Chapter

Book I, Chapter 3

## Context

Smith argues that improvements in art and industry naturally begin where water-carriage opens the whole world as a market, and only later extend to inland parts of the country. He uses examples from North American colonies and Mediterranean civilizations to demonstrate this developmental pattern.

--- ENTITY: inland parts of the country ---

# Inland Parts of the Country

## Definition

The interior regions of a country that are distant from sea-coasts and navigable rivers, having limited market access compared to coastal areas. These regions develop industry and division of labour later than coastal areas due to restricted market extent and higher transportation costs.

## Source Chapter

Book I, Chapter 3

## Context

Smith contrasts inland regions with coastal areas, explaining why industry and improvements in art are "much later in extending themselves into the inland parts of the country." He attributes this to the limited market size and higher transportation costs that restrict the division of labour in these areas.

# Market-Town Economy

## Definition

The economic organisation of small urban centres that provide limited but essential market access for surrounding rural areas. Market towns enable a degree of specialisation beyond what is possible in isolated villages, though they cannot support the full division of labour possible in larger cities.

## Source Chapter

Book I, Chapter 3

## Context

Smith uses the example of a porter who can find employment and subsistence only in a great town, not in a village or even an ordinary market-town. This illustrates how different sizes of markets support different degrees of specialisation and division of labour.

---
--- ENTITY: subsistence agriculture ---

# Subsistence Agriculture

## Definition

The agricultural practice in which farmers produce primarily for their own family's consumption rather than for market exchange. In subsistence agriculture, farmers must perform all necessary tasks themselves, preventing specialisation and limiting the division of labour.

## Source Chapter

Book I, Chapter 3

## Context

Smith describes how in the remote highlands of Scotland, every farmer must be "butcher, baker, and brewer for his own family," illustrating how limited market access forces self-sufficiency and prevents the division of labour even in basic economic activities.

# Economic Opportunity Geography

## Definition

The spatial distribution of economic opportunities based on geographical features, market access, and transportation infrastructure. Economic opportunity geography determines where different types of economic activities can be successfully pursued and at what scale.

## Source Chapter

Book I, Chapter 3

## Context

Smith's analysis shows how economic opportunities are geographically distributed: trading opportunities cluster along coasts, manufacturing opportunities develop along navigable rivers, while subsistence agriculture characterises isolated inland areas with poor market access.

--- ENTITY: market integration timeline ---

# Market Integration Timeline

## Definition

The historical sequence by which different regions become integrated into broader market systems, with coastal and riverine areas integrating first, followed by regions with artificial navigation improvements, and finally isolated inland areas. Market integration timeline explains the temporal patterns of economic development.

## Source Chapter

Book I, Chapter 3

## Context

Smith describes how industry naturally begins where water-carriage opens the whole world as a market, and it is frequently not till a long time after that improvements extend themselves to inland parts of the country, establishing a clear timeline for market integration.

--- ENTITY: economic spatial inequality ---

# Economic Spatial Inequality

## Definition

The persistent differences in economic development, specialisation, and productivity that exist between regions based on their geographical location and market access. Economic spatial inequality creates lasting disparities in wealth and economic opportunity across different areas.

## Source Chapter

Book I, Chapter 3

## Context

Smith's analysis demonstrates economic spatial inequality: coastal regions develop industry and specialisation, river regions achieve moderate development, while isolated inland areas remain at subsistence levels, creating persistent economic disparities based on location.

# Market Access Economic Potential

## Definition

The economic development possibilities available to a region based on its access to markets and trade routes. Market access economic potential determines the maximum level of specialisation, division of labour, and productivity that can be achieved in different locations.

## Source Chapter

Book I, Chapter 3

## Context

Smith shows how market access economic potential varies: coastal areas with water-carriage have high potential for development, river regions have moderate potential, while isolated inland areas have limited potential due to poor market access and high transportation costs.

--- ENTITY: economic development geography theory ---

# Economic Development Geography Theory

## Definition

The theoretical framework explaining how geographical features determine patterns of economic development, market formation, and the division of labour across different regions. Economic development geography theory provides the foundation for understanding why economic development occurs where and when it does.

## Source Chapter

Book I, Chapter 3

## Context

Smith's entire chapter presents economic development geography theory, showing how natural features like coastlines, rivers, and terrain determine market extent, how transportation costs affect specialisation possibilities, and why economic development follows predictable geographical patterns.

--- ENTITY: market-based economic geography ---

# Market-Based Economic Geography

## Definition

The study of how markets and their characteristics shape the geographical distribution of economic activities, specialisation patterns, and development across different regions. Market-based economic geography explains the spatial organisation of economic activities based on market access and transportation costs.

## Source Chapter

Book I, Chapter 3

## Context

Smith's analysis demonstrates market-based economic geography by showing how different market sizes and accessibilities create distinct patterns of economic activity: trading centres along coasts, manufacturing along rivers, and subsistence agriculture in isolated areas.

--- ENTITY: economic accessibility determinants ---

# Economic Accessibility Determinants

## Definition

The factors that determine how easily different regions can access markets and participate in exchange, including geographical features, transportation infrastructure, political arrangements, and population density. Economic accessibility determinants shape patterns of economic development and specialisation.

## Source Chapter

Book I, Chapter 3

## Context

Smith identifies multiple economic accessibility determinants: natural features like coastlines and rivers, artificial infrastructure like canals, political factors like control over waterways, and population density that creates market demand for specialised goods and services.

--- ENTITY: market extent economic impact ---

# Market Extent Economic Impact

## Definition

The effects that the size and reach of markets have on economic development, division of labour, and productivity. Market extent economic impact explains how larger markets enable greater specialisation and higher levels of economic organisation.

## Source Chapter

Book I, Chapter 3

## Context

Smith's central argument demonstrates market extent economic impact: larger markets enable greater division of labour, support full-time specialists, and allow for the development of complex economic activities that are impossible in smaller markets with limited exchange possibilities.

# Economic Development Spatial Patterns

## Definition

The predictable geographical arrangements of economic development that emerge based on market access, transportation costs, and the division of labour. Economic development spatial patterns show how economic activities cluster in certain locations while avoiding others.

## Source Chapter

Book I, Chapter 3

## Context

Smith describes clear economic development spatial patterns: industry clusters along coasts and navigable rivers, specialisation increases with market size, and economic backwardness characterises isolated
