How bad is human trafficking?

Adam pointed me to this review in the New Statesman by Brendan O’Neil of “Sex at the Margins: Migration, Labour Markets and the Rescue Industry” (Foyles, Amazon) by Laura María Agustín. Here is the core of the review:

Agustín points out that some anti-trafficking activists depend on numbers produced by the CIA (not normally considered a reliable or neutral font of information when it comes to international issues), even though the CIA refuses to “divulge its research methods”. The reason why the “new slavery” statistics are so high is, in part, that the category of trafficking is promiscuously defined, sometimes disingenuously so. Some researchers automatically label migrant women who work as prostitutes “trafficked persons”, basing their rationale on the notion that no woman could seriously want to work in the sex industry. The Coalition Against Trafficking in Women argues that “all children and the majority of women in the sex trade” should be considered “victims of trafficking”. As Agustín says, such an approach “infantilises” migrant women, “eliminating any notion that women who sell sex can consent”. Ironically, it objectifies them, treating them as unthinking things that are moved around the world against their will.

The reality is very different, the author says. Most migrant women, including those who end up in the sex industry, have made a clear decision to leave home and take their chances overseas. They are not “passive victims” who must be “saved” by anti-trafficking campaigners and returned to their country of origin. Rather, frequently, they are headstrong and ambitious women who migrate in order to escape “small-town prejudices, dead-end jobs, dangerous streets and suffocating families”. Shocking as it might seem to the feminist social workers, caring police people and campaigning journalists who make up what Agustín refers to as the “rescue industry”, she has discovered that some poor migrant women “like the idea of being found beautiful or exotic abroad, exciting desire in others”. I told you it was controversial.

One of Agustín’s chief concerns is that the anti-trafficking crusade is restricting international freedom of movement. What presents itself as a campaign to protect migrants from harm is actually making their efforts to flee home, to find work, to make the most of their lives in often difficult and unforgiving circumstances, that much harder. She writes about the “rescue raids” carried out by police and non-governmental organisations, in which even women who vociferously deny having been trafficked may be arrested, imprisoned in detention centres and sent back home - for the benefit of their own mental stability, of course. It used to be called repatriation; now, dolled up in therapeutic lingo, it is called “rescue”.

For all its poisonous prejudices, the old racist view of migrants as portents of crime and social instability at least treated them as autonomous, sentient, albeit “morally depraved”, adults. By contrast, as the author illustrates, the anti-trafficking lobby robs migrants of agency and their individual differences, and views them as a helpless, swaying mass of thousands who must be saved by the more savvy and intelligent women of the west and by western authorities.

It’s fascinating stuff and goes along with what I’ve previously said about prostitution:

[Slavery] aside (and that’s what people trafficking is - slave trading), you cannot simply save or rescue a prostitute. It is not a problem, if you consider it one, to be tackled. It is not something that you solve, once and for all. Prostitutes are people like everyone else and like everyone else, they think on the margin and respond to incentives.

In that entry I labelled human trafficking as slavery and I stand by that. Nevertheless, it would appear from Agustín’s work that the scale of the trafficking problem may be smaller than we commonly believe.

Thinking on the margin: prostitution (UPDATED)

One of the most important ideas in economics is that people think and act on the margin. By that I mean that we make our decisions as if we were looking at the costs and benefits of just one more. Just one more slice of pizza. Just one more minute on the bike in the gym. Just one more share of some stock bought. If we reckon the benefits of that one more to be greater than the cost of it, irrespective of what has come before and what may come after, we’ll typically do it. The point is that we optimise, or at least act as though we optimise. We may only optimise locally instead of globally (that last slice of pizza may have seemed like a good idea at the time, but it’s not much good for my health in general), but it’s still what we do.

The idea is by no means unique to economics. There is, at the least, an entire branch of mathematics devoted to it. But economists just love to point out that optimisation - and, therefore, thinking on the margin - applies to human behaviour just as well as it does to equations on a blackboard, and that realisation can sometimes lead to surprising, even counter-intuitive observations with serious consequences for public policy.

As I’ve mentioned before (here and here), Steven Levitt and Sudhir Venkatesh are currently finishing a paper on street prostitution in Chicago. They were able to study the provision of prostitution services during a predictable demand shock and discovered that the supply of prostitution services is rather elastic: a 63% increase in quantity was associated with only a 30% increase in price. More importantly, that increase came on three margins: an increase in supply from existing prostitutes (who, on average, only work 13 hours a week), a temporary in-migration of prostitutes from other areas and the temporary entry into the market of women who are not ordinarily willing to perform sex acts for money. Levitt and Venkatesh estimate that 43 of the 63% increase in the number of tricks came from existing prostitutes in the area and the remaining 20 from the in-migrating prostitutes and the temporary market entrants.

That third margin bears highlighting. Typical thinking about the topic holds that the choice to become a prostitute, if it is a choice at all, is a discrete [update:  I originally had "discreet".  It's certainly that :-) ] one; that women and a very few men first choose - or are compelled - to be a prostitute and only then consider what money they might make. The idea that some women might choose to start or stop being a prostitute in the face of a ten, five or even one dollar an hour change in the money available doesn’t make sense in this thinking. I believe that the reason for this is founded in a moral abhorrence at the very idea of prostitution - that in addition to any social or economic conditions faced by prostitutes, the act of prostitution itself is immoral. Since it has become au fait, among Western intelligentsia at least, to never accuse people of direct moral failure, it has also become the norm to conclude that all prostitutes were misled or forced into their position and thus need to be rescued. The terrible issue of people trafficking naturally lends support to this idea.

I do not want to belittle the tragedy and travesty that is people trafficking. It is a truly awful phenomenon and the fact that it exists at all, let alone in countries that are supposed to be based on freedom of the individual as a founding tenet, is abhorrent. It needs to be stamped out.

My concern is to highlight that not all prostitutes are forced into their profession. There really are women who, faced with an outside option of $7/hour, are not willing to be a prostitute for $25/hour, but are willing to do so for $35/hour. I have no doubt at all that - and this is important - the same statement would be true if you multiplied all of those figures by 10.

The upshot of this is that, slaves aside (and that’s what people trafficking is - slave trading), you cannot simply save or rescue a prostitute. It is not a problem, if you consider it one, to be tackled. It is not something that you solve, once and for all. Prostitutes are people like everyone else and like everyone else, they think on the margin and respond to incentives. If your concern is that prostitutes live in poverty, that they are compelled into their work by economic hardship, then you must work to improve their outside options. But at the same time, you should recognise that you will not be stopping prostitution from happening; you will simply be raising the minimum asking price. That will lower the quantity demanded, but it will never remove it altogether.

Update (5 April 2008):

See my new entry here. It would appear that maybe even the figures for human trafficking are overblown.
