On The Principles of Political Economy, and Taxation

Establishes labor as the foundation of exchangeable value, distinguishing value from utility and examining how capital accumulation and rent affect relative commodity prices.

Explains rent as the difference between productive lands of varying fertility, determined by demand for increasing population rather than absolute fertility.

Applies rent principles to mineral extraction, showing metals' values depend on production difficulty and mines pay rent analogous to agricultural land.

Distinguishes natural prices determined by production costs from temporary market price fluctuations caused by supply and demand variations.

Analyzes natural and market wages as regulated by subsistence costs, showing population growth ties wages to food prices and agricultural productivity.

Demonstrates profits fall with rising wages as capital accumulates and food production becomes more difficult, establishing inverse relationship between wages and profits.

Shows foreign trade cannot permanently raise profit rates and benefits derive from comparative advantage, not from increased national wealth in value terms.

Establishes fundamental tax principles distinguishing taxes on capital from income, and examines which classes ultimately bear different tax burdens.

Analyzes how taxes on agricultural products raise food prices and wages while lowering profits, falling ultimately on consumers rather than landlords.

Shows taxes specifically on rent fall entirely on landlords and cannot be shifted to consumers or affect agricultural production incentives.

Examines tithes as agricultural taxes that raise grain prices and act as bounties on importation, benefiting foreign producers at landlords' expense.

Analyzes fixed land-taxes as either taxes on rent or on produce depending on application, examining their effects on cultivation and revenue.

Examines how taxes on precious metals reduce mining output and raise their value, with effects differing from taxes on other commodities.

Analyzes how house taxes divide between occupier, building landlord, and ground landlord, ultimately shifting burdens based on land values.

Shows taxes on business profits raise commodity prices when money value unchanged, affecting different trades unequally based on capital composition.

Demonstrates wage taxes ultimately reduce profits despite raising money wages, as they increase production costs while commodity prices remain stable.

Examines how taxes on various manufactured goods and luxuries affect prices and distribution, with analysis of national debt and sinking fund effects.

Analyzes poor rates as taxes on land values that raise raw produce prices unequally, affecting landlords, farmers, and consumers differently.

Examines economic distress from trade disruptions and capital reallocation, arguing temporary suffering follows necessary economic adjustments.

Distinguishes value in exchange from wealth in necessities, showing abundance of commodities increases riches without necessarily increasing value.

Analyzes how capital accumulation lowers profit rates when food production costs rise, examining relationship between profits and interest rates.

Critiques export bounties and import prohibitions as inefficient, showing they divert capital unprofitably and ultimately benefit consumers abroad.

Examines bounties subsidizing domestic production as economically wasteful, raising commodity prices for consumers without permanent profit gains.

Critiques Smith's rent doctrine for confusing taxes on land with transfers to landlords, arguing taxes fall on consumers through price increases.

Analyzes colonial trade regulations showing they can benefit colonizing nations unfairly while restricting colonial commerce benefits.

Distinguishes gross production from net income available for distribution, showing taxation effects depend on net rather than gross revenue.

Examines paper currency, banking systems, and the role of precious metals as standards, arguing quantity must regulate value and stability.

Investigates why precious metals and necessities have different relative values in rich versus poor countries based on production costs.

Examines claims that taxes accumulate through middlemen, showing ultimate burden depends on production costs and market prices.

Establishes cost of production as ultimate price regulator rather than supply-demand ratios, which affect only temporary market prices.

Critiques Malthus's rent theory, arguing rent is value creation not wealth creation, and examining effects of falling corn prices on taxes.
