Exclusionary migration policies are gaining traction internationally. In the UK, the US, Germany, and most other regions of the Global North, we see stronger shifts towards immigration policy characterised by borders and exclusion. Foundational to this are our understandings of nationals’ and non-nationals’ right to inclusion within a nation’s borders. Economic migrants are increasingly met with hostility and suspicion (Tendayi Achiume, 2019). This hostility is supported by ideology and violent structures of international labour migration. To critically engage with these structures, we must expose the prejudice of eurocentrism underlying economic theories of migration. This prejudice distorts the social science and distracts from historical contexts (Amin, 1988). Eurocentric justification relying on colonial logic of the states’ ethical right to the exclusion of migrants must be challenged (Tendayi Achiume, 2019).
It is not yet well known that popular understanding of international economic migration is based on the eurocentric discipline of migration theory in mainstream economics. In these theories, migration is seen primarily through the lens of economic utility and growth. In true economics fashion, labour is a resource most efficiently allocated by the market. As such, there is an (eurocentric) assumption in the discipline that wage disparities and better labour conditions in the Global North are an endogenous result of economic development, without recognizing historical contexts. Economists’ bias undermines any holistic understandings of why people from the Global South immigrate to the Global North. Why do migration patterns replicate colonial ties so closely? And why is internal anti-immigrant policy ineffective at reducing labour migration?
Mainstream Migration Theory
Neoclassical Migration Theory (NMT), foundational to theory and policy, consists of a macro-and micro-economic level. The macro level outlines elements of the labour market equilibrium, the balance of labour supply and demand across regions, as the driver for labour migration. Labour is scarce in some regions, therefore wages are high; labour is abundant in others, therefore wages are low. Labour moves from low wage to high wage until wage disparities are minimised, achieving the new equilibrium. Labour migration takes place because of wage disparities and without them, there would be no migration (Massey, 1993). On the micro-level, the theory outlines individuals’ labour decisions. Workers migrate wherever labour is scarce, so they can secure higher wages in return for their skills. This behavioural prediction is in line with neoclassical economics, based on rational decisions of individuals to maximise income and utility.
Although NMT has evolved from these basic neoclassical foundations, it remains the baseline of how migration is more generally understood. Changes to the theoretical framework have been incrementally adapted through the expansion of the concept of utility. In the face of criticism to mainstream migration theory, the conceptualisation of the migrants’ personal cost-benefit analysis has changed. NMT focuses on the individual, while the succeeding theories – New Economics of Labour Migration and the Livelihoods Approach – expand decision making to households and families. The object of decision-making evolves from wage maximisation, to wage maximisation and risk minimisation, all the way to diversification of risk to maximise resources. Mainstream migration theory, which is an expansion of NMT, frames international labour migration as the economic and social decision of individuals based on opportunity differentials, rooted in a labour market equilibrium, and abstracting from historical and social context (Massey, 1993). The dimensions arguably expand to a more holistic understanding of utility, but the individualistic premise remains. At no point do such theories address global power structures underpinning the ability of people to migrate. Social and political phenomena are removed from their historical context and understood purely through concepts of expanded utility (Fine, 2000). Revised approaches patch up shortcomings of economic theories and fail to address the power relations and historical legacies of migration (Cross, 2020). All categories of social and geographical motivations are sooner or later encompassed by utility, feeding into the ultimate cost-benefit analysis that underpins contemporary mainstream.
This economic individualism constructs not only a limited but profoundly Eurocentric theoretical framework of migration theory that justifies exclusion. The individual decision of a migrant and their effort to maximise utility is set up against the right of a country to deny that decision and exclude the individual. It facilitates an international structure that constructs exclusion as the default and only deviates from this in cases that prove high utility to benefit receiving countries. The theoretical foundation of methodological individualism and the justification of exclusion is thus fundamentally linked. A nation’s right to exclude an individual is constructed or justified through the economic premise of rational decision making. Scholar Tendayi Achiume (2019) emphasises a key reason why individualism shapes migration policy and allows exclusion. Nationals and non-nationals are not seen as political equals and therefore states have different obligations to them. This creates a hierarchy of second-class citizens in which migrants become valuable through their economic contribution.
The World Bank’s Match and Motive Matrix, published in 2023, acts as a framework for receiving countries to navigate costs, benefits and obligations of international migration. Receiving countries can classify whether migrants are of benefit to them through the alignment of migrants’ skills and attributes with the needs of destination countries (Do and Özden, 2023). This Matrix is a perfect illustration of the uneven power structure between an individual migrant and a receiving country. Costs of integration along with social and economic costs are measured against benefits of skills. ‘A strong match occurs, for example, when the labour market benefits of the migrant exceed the costs of integration, while a weak match arises when the costs outweigh the benefits.’ (ibid, p.26). Underlying this analysis, is the benefit an individual migrant can contribute to a receiving country in their production structure.

Figure 1. Match and Motive Matrix (Do and Özden, 2023)
The report claims that labour migration is necessary for all countries to meet their labour shortages (Do and Özden, 2023). It legitimises the North’s way to assess the utility value of migrants from the Global South, and abstracts countries and individuals from their historical and political context (Blaney, 2020) to misleadingly neutralise the matrix. This methodological abstraction is not only insufficient but also harmful, as it holds significant policy implications. It prioritises economic utility and frames migrants as workers in a cost-benefit analysis, positioning them as second-class citizens that are by default excluded and exposed to exploitation and criminalisation. The assertion of receiving countries’ rights to exclusion are based on this framing of encounters between Global South peoples and Global North nation-states (Tendayi Achiume, 2019). This speaks to individualism through economic ideologies’ impact on international migration.
Colonizers like the UK have long relied on internal and foreign cheap labour to fill certain positions in the value chain. Frameworks such as the Match and Motive Matrix support this need as they clear paths for countries to evaluate what migration incentives would be needed to meet their labour needs, while there is little recognition of the systemic reproduction of the underlying neo-colonial structures. What is missing in this framework is the fact that labour migration is deeply embedded in the capitalist mode of production and plays an important role in managing labour supply (Cross, 2020). Cheap labour is the engine of neoliberal capitalism, especially via outsourcing and dismantling of labour protection since the 1980s (Delgado Wise, 2014).
The Expansion of Irregularity
Through the presented framework, migrants’ decision to move is individualised, yet their labour is systematically exploited. The same logic that justifies exclusion, also facilitates exploitation. ‘Illegal’ or ‘irregular’ immigrants are particularly treated as excludable political strangers (Tendayi Achiume, 2019). Yet irregularity is not a self-producing phenomenon but is rather facilitated by states. Countries like the USA and the UK continue to expand the boundaries of irregularity. Eurocentric and exploitative views on labour migration facilitate large levels of irregularity under which cheap labour can be endlessly exploited. The state does not only allow labour exploitation through lack of regulation but also actively facilitates it by expanding irregularity. In the UK, restriction of labour mobility is directly shaped by ties between Britain and its former colonies. Åhlberg’s work (2022) on migration illustrates the growing parameters of irregularity, encompassing several migrants, even those whose status was previously secure. She emphasizes how irregularity works in favour of capitalist accumulation. Irregular migrants are subject to major labour exploitation due to a lack of social protection and the power imbalance between employer and employee. Employers can capitalise on vulnerabilities of migrant workers and keep their labour costs low (Åhlberg, 2022). Risk of labour exploitation is particularly prevalent when under an insecure migration status and working in low-paid jobs (Boelman, 2023). In addition, there is a serious risk of falling into a ‘hostile environment’, a series of measures that aim at making it difficult or even unbearable for undocumented migrants to live in the UK. This includes barriers to accessing housing, healthcare, and bank accounts (Boelman, 2023). Significant increases in the number of people classified as irregular, have led to heightened labour exploitation (Åhlberg, 2022). Cross (2020) suggests that the rise of labour exploitation is a function of capitalist accumulation. The making of irregularity facilitates and justifies exploitation under the colonial logic of excluding migrants.
Decolonising Labour Migration
Economic migration theory needs to decolonise and shift towards alternative understandings of labour mobility. The discipline must reorganise focus from economic utility towards balancing power structures based on historical legacies (Cross, 2020). Addressing eurocentric bias brings us closer to recognising the underlying logic that justifies global exploitation. The labour exploitation that continues between Global North and Global South countries must be acknowledged. Labour conditions including wages of the Global North are not endogenous to these countries. To recognise Global South countries’ contribution to prosperity in the Global North would mean to recognise the countries’ people as equally deserving of its benefits and therefore to migrate with the right to inclusion (Tendayi Achiume, 2019). This challenges the role of methodological individualism by explicating the historical enduring of hierachical and exploitative structures. Interdisciplinary insights from sociology and political economy that incorporate perspectives that allow for an understanding of historical legacies of exploitation should be spotlit. Theoretical frameworks must be reframed.
More attention should be focused on radical reimaginings of migration following framings such as those proposed by Zolberg (1989) and Tendayi Achiume (2019). They are historically embedded in power relations and initiate a radical reordering of priorities. Such critical scholars play a crucial role in challenging mainstream migration theory that sustain the unjust systems of exclusion dominating current political narratives. Zolberg (1989) proposes migration as a global system of equal liberties where disparities exist, yet everyone holds equal liberties to mobility. There is a collective obligation to provide entry and enable the right to exist. (Zolberg, 1989) Tendayi Achiume’s understanding of neo-colonial structures leads her to reject frameworks of economic migration that insist on exclusion and instead positions people as co-sovereign with equal right to inclusion and self-determination.
