Welfare, Production & Economic Choice

← Back to Domain-Specific Families

Abstractions about economic allocation, production, preferences, uncertainty, and welfare evaluation. They include equilibrium and convergence, capacity and productivity, inequality measures, utility and willingness to pay, trade distortions, discrimination, and development outcomes.

45 abstractions in this family — domain-specific abstractions that sit near one another in structural-signature space (k-means over structural-signature embeddings). Each is shown with its short description.

• Allocative efficiency — An economic state in which resources and output mix cannot be reallocated to make someone better off without making another worse off, often characterized under competitive assumptions by price equaling marginal cost.
• Applied general equilibrium — Numerical economy-wide modeling that calibrates interdependent markets, agents, technologies and policy constraints to compute counterfactual equilibrium prices, production, income and welfare.
• Atkinson index — An inequality measure equal to the proportional mean income society could forgo while retaining the same equally distributed equivalent welfare at a chosen inequality-aversion parameter.
• Breusch–Godfrey test — A regression diagnostic testing residual serial correlation through an auxiliary regression that permits higher-order autocorrelation and lagged dependent regressors.
• Burstable billing — A network-capacity charging method that bills a high percentile of sampled traffic, allowing short bursts above commitment without pricing every peak as sustained demand.
• Capacity utilization — The ratio of actual output during a period to the potential output achievable from a defined stock of productive capacity under a stated engineering or economic convention.
• Capital intensity — The amount of fixed or real capital used relative to labor or another production input at a process, firm, industry or economy level.
• Commuting zone — A county-based geographic aggregation approximating a self-contained local labor market from observed home-to-work commuting flows.
• Compensation principle — A welfare-economic decision rule favoring a change when its gainers could hypothetically compensate its losers and still retain a gain.
• Contract curve — The locus of Pareto-efficient allocations in an Edgeworth box where the two consumers’ indifference curves are tangent or a boundary constraint binds.
• Convergence (economics) — The hypothesis or observed tendency for initially poorer economies to grow faster than richer ones and thereby narrow differences in per-capita income or productivity.
• Demerit good — A good judged to be overconsumed because consumers undervalue harms to themselves, motivating paternalistic taxation, regulation, or information policy.
• Economic opportunism — Self-interested economic conduct that exploits incomplete rules, information asymmetry or bargaining vulnerability through deception, strategic withholding or norm evasion.
• Expenditure cascades — A consumption spillover in which higher spending by top-income households raises local comparison standards and induces successive spending increases down the income distribution.
• Expenditure function — The minimum spending needed at given prices to attain a specified utility level.
• Feldman–Mahalanobis model — A two-sector development model prioritizing investment in capital-goods capacity to raise the long-run ability to produce both capital and consumer goods.
• Friedman–Savage utility function — A wealth-dependent expected-utility curve with alternating concave and convex regions intended to explain simultaneous insurance purchase and lottery play.
• Full employment — A macroeconomic condition in which employment is as high as sustainably attainable, allowing frictional and structural unemployment but no material deficient-demand unemployment.
• Human Development Index — A composite national index combining normalized longevity, education, and income dimensions.
• Immiserizing growth — A trade-theoretic case in which output growth worsens a large exporting country’s terms of trade enough to reduce national welfare.
• Knightian uncertainty — Uncertainty about outcomes for which no well-grounded probability distribution is available, contrasted with measurable risk.
• Leontief utilities — A fixed-proportions utility model in which bundle value is the minimum of each good’s quantity divided by its required coefficient.
• Lerner symmetry theorem — The trade-theory result that an ad valorem import tariff has equivalent real effects to an equal export tax under specified general-equilibrium assumptions.
• Marginal revenue productivity theory of wages — A labor-demand theory in which a profit-maximizing firm hires workers until the wage equals labor's marginal product multiplied by the marginal revenue from additional output.
• Market distortion — A departure from a declared competitive benchmark that changes prices, quantities or incentives so decentralized choices no longer produce the benchmark allocation.
• Monotone preferences — Preferences under which having weakly more of every good and strictly more of a qualifying good is never worse or is strictly better.
• Multi-attribute utility — A utility representation assigning values to outcomes described by several attributes while encoding tradeoffs, interactions and uncertainty preferences.
• Net (economics) — A value remaining after specified additions and deductions are applied to a corresponding gross amount, with the modifier meaningful only when the adjustment boundary is named.
• New trade theory — A family of international-trade models explaining intra-industry trade and specialization through increasing returns, product differentiation, imperfect competition and market size.
• Non-convexity (economics) — An economic setting in which preferences, technologies or feasible sets violate convexity, allowing indivisibilities, increasing returns and multiple or unsupported competitive outcomes.
• Pareto index — The shape parameter of a Pareto income or wealth distribution, often interpreted as a tail-inequality or concentration exponent.
• Polytomous choice — A discrete-choice setting in which a decision maker selects among more than two mutually distinguished alternatives.
• Privileged group — A collective-action group containing at least one member whose private benefit from a public good exceeds the full cost of supplying it.
• Production (economics) — The organized transformation of material and immaterial inputs into goods or services, represented by feasible production sets, technologies, costs, and output relations.
• Productive capacity — The maximum sustainable output an economy, organization, asset or resource base can produce with its available capabilities and linkages.
• Ragnar Nurkse's balanced growth theory — A development theory advocating coordinated simultaneous investment across complementary sectors to enlarge markets and escape low-income demand constraints.
• Real net output ratio — The share of a firm’s total production value created internally rather than purchased as externally produced goods and services.
• Signalling (economics) — The strategic use of observable actions or attributes to convey credible information about otherwise hidden qualities in a market or game.
• Simple commodity production — A mode of commodity exchange in which independent producers own their means of production and sell their own products to obtain other use values.
• Simulations and games in economics education — Instructional activities that combine rule-governed play with an economic model so learners experience incentives, interaction and aggregate outcomes.
• Subjective theory of value — The economic theory that goods derive exchange-relevant value from agents’ marginal evaluations rather than inherent substance or embodied labor alone.
• Taste-based discrimination — An economic model in which decision makers accept a material cost to avoid interaction with a disliked group, producing unequal market outcomes unrelated to productivity.
• Transformation in economics — A sustained shift in the dominant composition of economic activity, employment, production, institutions, and capabilities across sectors or modes of organization.
• Uncertainty effect — A choice anomaly in which a known lottery is valued below its least valuable possible outcome.
• Willingness to pay — The maximum amount of money or other numeraire an actor would exchange for one unit of a good, service, outcome, or risk change under a declared decision context.
