Monopsony – Chasing Tales

NB: Hello! This essay argues that the distribution of bargaining power within relationships can follow the same structure as those seen in labour markets. That doesn’t mean there is no love in the relationships, and the latter is not the argument: there can be love, and also coercion, dependency, and obligation at the same time.

NB 2: I use ‘externality’ here somewhat more broadly than its strict textbook meaning, to describe costs displaced onto people whose constrained position prevents them from refusing them. Basically I want to understand WHY this issue persists.

A monopsony¹ (from the Greek for “single buyer”)² is a market where there is only one buyer, or so few buyers that sellers have almost nowhere else to go. The result of a monopsony is that the employer can pay as little as they can get away with. The wage is no longer determined by what the work is worth. It is determined by what the worker can be made to accept.³

In a competitive labour market, the mechanism that prevents this is called the exit option⁴: the credible threat a worker can leave and sell their labour elsewhere. The existence of this threat disciplines employers into treating workers reasonably. Rational employers therefore pay enough to retain people. The exit option is, in a very precise sense, the source of a worker’s bargaining power. It is the economic foundation of their dignity in a transaction.

The labour economist Alan Manning spent much of his career documenting that monopsony is not a rare edge case.⁵ ⁶ It is the normal condition of low-wage labour markets. Most workers who are paid badly have far fewer real alternatives than textbooks assume.⁷ They do not leave because leaving is costly: in time, in income disruption, in social upheaval, in the loss of benefits or seniority.⁸ The exit threat is technically available but practically weak, and employers know it.

However, Manning’s framework still treats monopsony as a matter of degree- workers have some options, just not enough.⁹ The more interesting question is what happens when the exit option is effectively nonexistent.

While workers in most of these situations are formally free, because no law prevents them from quitting, formal freedom to exit and the ability to actually leave are different things.¹⁰ A worker who is free to quit but will lose their housing, their immigration status, their children’s stability, or their community’s acceptance has both, a formal exit option and a non-credible one.¹¹ ¹² ¹³ That is, a formal right to leave is meaningless, because exercising it is catastrophically costly.

No practical exit
Economists Carl Shapiro and Joseph Stiglitz formalised in 1984 why wages tend not to fall to the absolute minimum even in imperfect markets.¹⁴ Their argument: because employers cannot perfectly monitor workers, they must pay a wage high enough that losing the job is a genuine punishment- which means, workers perform because they have something real to lose. This is called the efficiency wage.¹⁵ In their model, the punishment for shirking is unemployment: if you are fired, you expect a spell without work before getting another job, so you value your wage enough to exert effort. If there is nowhere else to go, there is no need to pay that efficiency premium; the only constraint becomes how little can be paid without provoking refusal or collapse. Compensation trends downward toward what is called the reservation wage.¹⁶

The reservation wage is the minimum wage at which a person will remain in the arrangement rather than exit.¹⁷ In a free market, the reservation wage is set by the worker’s next best alternative, such as another job.¹⁸ In a captive supply market, the next best alternative is often poverty, homelessness, violence, or social exclusion.¹⁹ So, what the worker can be made to accept (the wage or non monetary compensation offered) is no longer determined by what their work is worth, but by how bad things would have to get before leaving becomes preferable to staying.²⁰

This is what I now think of as “captive” supply markets, which are situations where exit costs are high enough to eliminate the exit option as a real constraint on the buyer’s behaviour. The worker is not just poorly positioned in a negotiation: they are structurally trapped, and the compensation they receive reflects the entrapment more than it reflects anything about the work itself.

So, a captive supply market exists when all three conditions hold simultaneously:

The worker supplies economically valuable labour;
Exit is formally available but practically non-credible; and
The beneficiary captures value while offloading substantial costs onto the worker.

Clearly, coercion does not require chains. A captive supply market can be created purely by making exit expensive. While the barriers may vary (debt, legal precarity, social stigma, the threat of violence, the absence of financial independence, moral obligation to a dependent person), their economic function is identical: they all raise the cost of leaving until leaving is no longer a credible option, and the wage, in whatever form it takes, falls accordingly.

The externality²¹
An externality is an unintended cost or benefit that affects a third party who is not involved in the original transaction.²² Pollution is the textbook case²³: when a factory dumps waste into a river, and the cost of cleaning it falls on communities downstream who were never party to the factory’s transactions. The factory’s product appears cheaper than it really is because the true cost, which includes the cost of river cleanup, the loss of river-based life, healthcare cost of land-based life forms that depend on that river among others, was not included in the retail price.

The product appears artificially cheap because part of the real cost has been transferred to people outside the transaction.²⁴ In captive labour markets, the externality is not only financial but intertemporal and social: the costs are borne by future selves, children, public health systems, kinship networks, or subordinated dependents while remaining invisible to the immediate transaction.²⁵ ²⁶

Captive labour pricing works identically. The buyer captures the value of the work at a discounted price. The true cost of producing that work, such as the physical toll, the foreclosed opportunities, the psychological erosion, is transferred to whoever has the least power to refuse it. They absorb it in their bodies, in their shortened lives, in the disadvantages their children inherit.

Contemporary captive labour markets include unpaid care work²⁷ ²⁸ ²⁹, caste-assigned sanitation labour³⁰, undocumented labour³¹ ³², and migrant domestic work under systems like kafala³³ ³⁴. Their surface forms differ, but their economic structure is similar: exit is formally available yet practically catastrophic, allowing labour to be priced according to the worker’s vulnerability rather than the value of the work performed.

What is work?
The standard definition of work in economics is human labour or purposeful activity that contributes to the production of goods and services.³⁵ ³⁶

Yet this definition becomes unstable once labour occurs outside ordinary market transactions. Many forms of economically necessary work, especially domestic, emotional, and care labour, are excluded from formal accounting not because they lack productive value, but because they are organised through obligation, intimacy, and social expectation rather than wages.³⁷ The fact that some work happens in offices and is invoiced, while some happens in homes and is treated as duty, changes its visibility and compensation, not its economic function.

My argument is that the cost of producing this work is the externality.

Here’s the flow: remove credible exit → bargaining power collapses → compensation disconnects from value → costs are externalised (that is, someone not part of the transaction bears it).

Gendered labour as the case study
Women’s unpaid and underpaid labour is perhaps the largest and most normalised instance of captive supply pricing in the world economy.³⁸ ³⁹ ⁴⁰ ⁴¹ ⁴² ⁴³ ⁴⁴

Within households, the informal negotiation over who does what is structured by expectations about gender roles that precede any individual relationship and constrain choice long before any specific argument about doing dishes is had.⁴⁵ ⁴⁶ ⁴⁷
Occupational segregation channels women into lower-paid sectors such as care, cleaning, administration, teaching.⁴⁸ ⁴⁹ ⁵⁰
Women’s financial dependence on male partners in many parts of the world limits their exit options independent of any legal restriction.⁵¹ ⁵²

The result is a global pattern in which women produce an enormous share of economically essential work and are compensated for only a small fraction of it.

The undervaluation of girls and women is not irrational within the terms of the societies producing it. Four simultaneous mechanisms work to produce it, compounding each other across a lifetime and across generations. These are:

Underinvestment in Human Capital: Across societies where captive female labour is most entrenched, families invest less in daughters than in sons across nutrition, schooling, and access to mobility and opportunity outside the home.⁵³ ⁵⁴ ⁵⁵ The economic logic of this, however brutal, is not irrational within the terms of the system producing it: the parents bear the cost of the investment; the returns flow elsewhere.⁵⁶ ⁵⁷
Employment Exclusion: Even a well-educated woman in many societies faces restrictions on where she can go, which jobs are culturally permissible for her, and whether her family and community will tolerate her working outside the home at all.⁵⁸ ⁵⁹ Harassment in public spaces, transportation that is unsafe or unavailable, workplaces that require mobility, long hours, or physical presence in male-dominated environments, all of these function as barriers not to her skills but to her ability to convert those skills into independent income.⁶⁰ ⁶¹ ⁶²
Cultural Conditioning: The third mechanism is the most durable: cultural conditioning. Girls are taught from early childhood to perform domestic and care work.⁶³ ⁶⁴ ⁶⁵ They are praised for doing it well, incorporated into household routines as junior labour, and given care responsibilities for younger siblings and elderly relatives as a matter of course. Over generations this becomes culture, meaning it no longer requires active enforcement because it has been internalised.⁶⁶ ⁶⁷ A woman who has internalised that care work is her duty and identity is less likely to name it as labour, less likely to expect compensation, and less likely to experience its absence as deprivation.⁶⁸ The externality becomes invisible even to the person absorbing it. Culture is how the captive supply market reproduces itself without requiring chains or contracts in every generation.
Penalty for Remaining Unmarried: The fourth mechanism enforces the system when the others are insufficient: the social penalty for being an unmarried woman. Unmarried women are a source of anxiety for their families, a subject of social judgment.⁶⁹ ⁷⁰ ⁷¹ ⁷² ⁷³ It functions as a threat that disciplines women into accepting whatever marriage terms are available rather than holding out for better ones or refusing marriage altogether because a woman who knows that the alternative to this marriage is social exclusion and family shame will accept conditions she might otherwise refuse.⁷⁴ ⁷⁵ ⁷⁶

None of these four mechanisms requires any individual act of malice. Each is self-reinforcing. Together they ensure that a woman arrives at marriage already holding a weak bargaining position, with few realistic outside options, in a body and mind that has been taught to expect limited compensation for substantial work, in a society that will punish her severely for leaving.

The full scale of what this produces is documented here.

Sealing the exit
A worker’s reservation wage (the minimum at which they will accept an arrangement rather than exit) is set by their next best alternative. For most people, the practical floor of that alternative is determined by assets: property, savings, collateral, a claim on family wealth that can be converted into housing, income, or the ability to start over. Assets are what make exit materially possible, as distinct from legally available.⁷⁷ ⁷⁸

In much of India, and across many societies, inheritance flows primarily through sons.⁷⁹ ⁸⁰ ⁸¹ This has a precise economic consequence: a son who inherits land, property, or a family business acquires fallback income, housing security, collateral against which to borrow, and an independent economic base that raises his reservation wage in any subsequent negotiation.⁸² ⁸³ He can afford to refuse bad terms because he has something to fall back on.

A daughter in the same family, whose notional share of family wealth is instead directed into her wedding, her jewellery, and her dowry^{(money and assets paid to a man to marry a woman)}, receives something categorically different: consumption expenditure rather than productive assets.⁸⁴ ⁸⁵ Jewellery transferred to the marital household is typically controlled by her in-laws, not by her.⁸⁶ ⁸⁷ ⁸⁸ Wedding expenditure is gone the day after the wedding. Dowry is transferred to the woman’s husband and his family, not to the woman marrying.

The distinction matters because productive assets generate future bargaining power: they make exit materially survivable, even if not socially so.

Expenditure on marriage ceremonies does not create future bargaining power for either the woman or her family. A family that spends equivalent sums on a son’s inheritance and a daughter’s wedding has not treated them equally in any economically meaningful sense.⁸⁹ ⁹⁰ It has given one child the material foundation to survive exit from any future arrangement, and the other child a one-time transfer that strengthens the household receiving her while doing nothing to strengthen her position within it.⁹¹

Son preference is often treated as the root cause, or the cultural attitude from which everything else follows. But the evidence suggests the causal chain runs in the other direction. Families prefer sons not primarily because of irrational prejudice but because, under systems where sons inherit property, stay with aging parents, and provide old-age support while daughters leave and their income accrues to another household, sons are the genuinely better economic investment within the terms of that system.⁹² Son preference is the output of an incentive structure, not its origin.⁹³ Which matters because it means changing the attitude without changing the incentive structure will not work, as Duflo’s research makes explicit.⁹⁴ ⁹⁵ The attitude reproduces itself as long as the incentives that produced it remain intact.

To be noted, India’s Hindu Succession Act was amended in 2005 to give daughters equal inheritance rights to agricultural land.⁹⁶ ⁹⁷ Studies find significant gaps between legal entitlement and actual inheritance, particularly in rural areas, driven by social pressure on daughters to waive their claims in favour of brothers in exchange for ongoing family support.⁹⁸ ⁹⁹ ¹⁰⁰ ¹⁰¹

Dowry
In a normal labour market, even a severely monopsonistic one, the employer pays the worker something.¹⁰² The power asymmetry means the wage is suppressed below what the work is worth, but payment flows toward the worker.¹⁰³ In the dowry system, payment flows in the opposite direction.¹⁰⁴ ¹⁰⁵ ¹⁰⁶

In many environments where dowry remains prevalent, marriage functions not only as a personal relationship but also as a system of economic allocation and social risk management.¹⁰⁷ ¹⁰⁸ Transfers often scale with the groom’s education, earning potential, caste position, migration prospects, or family status, revealing that these arrangements are not treated purely as romantic unions. The groom’s household receives capital upfront, while the bride is expected to provide long-term domestic labour, reproductive labour, care work, and social continuity within the household.₁₀₉ ₁₁₀ ₁₁₁ ₁₁₂ Where exit for women is difficult, these arrangements can become structurally extractive even when they are socially normalised.

The sunk cost of the dowry becomes a trap with a second direction of force. The bride’s family, having transferred substantial wealth to make this marriage happen, has their own financial and reputational reasons not to help her leave.¹¹³ ¹¹⁴ Admitting the marriage has failed means admitting the investment has failed, potentially losing the access and social position the transferred wealth created, publicly acknowledging a failed arrangement, and in families with unmarried daughters, damaging those sisters’ own marriage prospects.¹¹⁵ ¹¹⁶ ¹¹⁷ The people the woman might have turned to have been financially and reputationally conscripted into keeping her in place.

This is the structure that enables dowry harassment, including demands for additional transfers after the marriage, backed by the implicit threat that refusal will be punished through the woman.¹¹⁸ The demands follow a precise economic logic. The groom’s household has identified that the woman cannot leave and that her natal family cannot afford to let her.¹¹⁹ They extract accordingly.¹²⁰ The bride’s family faces a choice between paying more and conceding total loss.¹²¹ ¹²² At the extreme end of this chain of constrained choices are the deaths the National Crime Records Bureau records annually.¹²³ ¹²⁴

Markets are often described as self-correcting: if a transaction is unfair, one party walks away, and competition disciplines the other into offering better terms. This is how the exit option is supposed to work. And in markets where exit is genuinely available, it does work, imperfectly but directionally.

But captive supply markets do not self-correct, and the reason is the externality. The cost of the arrangement falls on the worker, not on the household extracting the labour. The household captures the benefit without paying the true cost. There is no transaction between the person who captures the benefit and the person who pays the cost. There is no price signal connecting them. The market cannot correct what it cannot see. And what it cannot see is everything absorbed by the person who cannot leave.

None of this means every household, or even most households, consciously behave this way, nor that affection and mutuality are absent from intimate life. The claim is narrower: where exit is materially difficult, bargaining power shifts accordingly, and social systems organised around constrained exit will tend to undervalue the labour of the less mobile party even when the individuals involved experience genuine attachment to one another.

That is why captive supply markets persist. And it is why we keep hearing about dowry deaths, followed by inconsolable natal families demanding justice for daughters they had earlier urged to “adjust” to the very conditions that eventually led to their deaths.
