Artificial Intelligence, Labour Income and Effective Demand: A Theoretical Framework for the Distributional Absorption Threshold of AI-Induced Productivity

Artificial intelligence (AI) may raise productivity by automating tasks, augmenting human work and reducing information-processing costs. Yet productivity gains are not necessarily converted into broadly shared purchasing capacity or fully absorbed output. This conceptual review develops the notion of the Distributional Absorption Threshold of AI-Induced Productivity, defined as the point at which AI-related productivity growth outpaces the growth of broadly distributed real purchasing power and household consumption. The framework links AI-induced productivity to labour income, income distribution, prices, investment, fiscal redistribution, external demand and effective demand. It distinguishes a favourable transmission path, in which productivity gains support wages, disposable income, consumption and output absorption, from a critical path, in which weak distributive transmission may generate absorption tension. The review formulates conceptual propositions and preliminary operational indicators for future empirical research while treating the threshold as an analytical construct rather than a fixed empirical constant. Its contribution is theoretical: it reframes the AI productivity debate beyond both technological optimism and automation anxiety by connecting technological change, distribution and demand-side realisation.

Artificial intelligence has become one of the central technologies through which contemporary economies seek to increase productivity, reorganise work and strengthen competitiveness. Recent advances in machine learning and generative AI have intensified this debate because AI systems are no longer confined to narrowly defined routine processes. They increasingly affect prediction, language, coding, design, customer interaction, professional services and knowledge-intensive tasks. For this reason, AI is often discussed as a potentially general-purpose technology whose economic effects depend on complementary innovation, organisational adaptation, skills, data infrastructure and institutional conditions [1][2][3].
The productivity potential of AI is increasingly documented at the level of specific tasks, workers and firms. Experimental and field evidence suggests that generative AI can reduce task completion time, improve output quality and support productivity in activities such as writing, customer support and professional consulting [4][5][6]. At the same time, these effects appear to be heterogeneous. They depend on task characteristics, worker experience, organisational context, capability boundaries and the ability of firms to redesign workflows around AI tools. AI should therefore be approached as a technology with significant productivity potential, but not as a mechanical source of immediate and uniform macroeconomic productivity growth.
A large part of the public debate on AI has focused on the possibility of job displacement. This concern is legitimate, but it is not sufficient for understanding the macroeconomic implications of AI-induced productivity growth. The task-based literature has shown that technological change may substitute some tasks, complement others and create or reinstate new forms of work [7][8][9][10]. AI should therefore not be interpreted only through the lens of technological unemployment. Employment displacement is one possible channel, but productivity gains may also affect labour income through slower wage growth, reduced hours worked, changing bargaining power, labour-market polarisation, declining labour share or the concentration of gains in profits and capital income.
This article starts from a broader macroeconomic question: even if AI increases productivity, under what conditions are the resulting gains transformed into broadly distributed real purchasing power and effective demand?
The question matters because productivity growth expands the capacity to produce, but it does not automatically ensure that additional output will be absorbed by the market. The economic realisation of productivity gains depends on demand channels, including household consumption, investment, public expenditure and external demand. It also depends on the distribution of income between labour and capital, the extent of redistribution, price dynamics and the marginal propensity to consume across household groups.
To capture this problem, this conceptual review develops the notion of the Distributional Absorption Threshold of AI-Induced Productivity. The concept refers to the point beyond which productivity gains associated with the adoption or use of AI are no longer accompanied by proportionate increases in broadly distributed real purchasing power and household consumption. In simplified terms, the threshold becomes relevant when the rate of AI-induced productivity growth persistently exceeds the rate of growth in broadly distributed real purchasing power. The concept was initially formulated as a definitional contribution [11], and the present review develops it into a wider theoretical framework.
The contribution of the review is threefold. First, it reframes the debate on AI and productivity by shifting attention from technological efficiency alone to the distributive and demand-side realisation of productivity gains. This contribution does not replace existing theories of effective demand, underconsumption, wage-led growth or distribution-sensitive growth. Rather, it applies and extends their central insight to the specific case of AI-induced productivity by asking how technology-related productivity gains are transmitted into labour income, household purchasing capacity and demand-generating expenditure. In this sense, the novelty of the framework lies not in proposing a new standalone productivity-pay indicator, but in specifying an AI-specific absorption mechanism that links productivity gains, distributive transmission and demand-side realisation. Second, the review distinguishes between a favourable transmission path, in which AI-induced productivity gains support wages, purchasing power, consumption and output absorption, and a critical transmission path, in which productivity gains are weakly transmitted to household income and effective demand. Third, it proposes a conceptual basis for future empirical operationalisation through indicators such as the productivity-real labour income gap and the absorption tension indicator, while recognising that such indicators are preliminary and require further empirical validation.
This review is theoretical and conceptual in nature. It follows a conceptual review approach rather than a systematic review protocol. The literature is used to develop, position and delimit a theoretical framework, not to provide an exhaustive mapping, bibliometric analysis or quantitative synthesis of all studies on AI, productivity and labour-market outcomes. The review draws selectively on bodies of literature directly relevant to the proposed construct, including research on general-purpose technologies and AI-related productivity, task-based approaches to technological change, labour income and functional income distribution, and Keynesian and Kaleckian perspectives on effective demand and distribution-sensitive growth. Empirical studies are considered where they clarify mechanisms relevant to the framework, including task-level productivity effects, occupational exposure to AI, wage and employment channels, and possible indicators for future empirical operationalisation.
The literature was selected purposively according to its conceptual relevance to the framework, rather than through an exhaustive database-screening procedure. Sources were included when they contributed directly to one or more of the following analytical components: AI as a productivity-enhancing technology, task-based technological change and AI exposure, labour income and functional income distribution, household consumption and effective demand, or the possible operationalisation of AI adoption, productivity, income and demand indicators. Priority was given to peer-reviewed academic contributions, established theoretical works and institutional sources that provide comparable indicators or policy-relevant evidence. Studies were not included merely because they addressed AI in general, but because they clarified mechanisms linking AI-related productivity to labour income, purchasing power, consumption or demand-side absorption. The literature was analysed interpretively and synthetically in order to define concepts, identify transmission channels, formulate propositions and delimit possible empirical indicators, rather than to produce a bibliometric mapping, frequency count or meta-analytic estimate.
Accordingly, the manuscript does not claim to offer a systematic literature review, a meta-analysis or an empirical test of the proposed threshold. For this reason, no PRISMA flow diagram, formal search protocol or inclusion-exclusion procedure is reported. This is a limitation of scope rather than a claim of exhaustive coverage. The article does not claim that a distributional absorption threshold has already been reached in any specific economy, nor does it assume that AI necessarily produces mass unemployment or demand weakness. Its purpose is to clarify concepts, integrate mechanisms and formulate propositions that future empirical research may examine.
The review is structured as follows. Section 2 discusses AI as a productivity-enhancing technology and distinguishes between productive capacity and economic realisation. Section 3 examines AI, labour tasks and income distribution. Section 4 develops the link between labour income, household consumption and effective demand. Section 5 defines the Distributional Absorption Threshold of AI-Induced Productivity and presents the favourable and critical transmission paths. Section 6 formulates the conceptual propositions of the article. Section 7 discusses possible indicators and research designs for future empirical operationalisation. Section 8 presents the theoretical and policy implications of the framework, and Section 9 concludes by identifying future research directions.
