I had a pre-programmed blog post on the issue of the minimum wage and poverty which was preempted by Mark Koyama (a blogger here at Notes on Liberty). The tweet is below and it has forced me to adjust the post.
An important & often neglected point. Minimum wage is s bad anti-poverty tool even if employment effects are zero https://t.co/lVEqwEhglz

Mark is absolutely right! Let me explain why with my own spin on it.
First of all, the demand curve slopes downwards – always. However, the method of adjusting to price changes (wages are a price and the minimum wage is a price control) is not an empirical constant. I am unlikely to fire workers for a 1% in the inflation-adjusted minimum wage. Firing workers implies transaction costs that are dependent of context (for example, if I am friend with my employee, this is a transaction cost in the form of a lost friendship), firm size (I won’t fire my only employee which represents 50% of my output for a 1% hike in MW) laws (firing and hiring regulations), institutions (social institutions, reputation, norms), my clientele (how elastic is their demand) and technological alternatives. For a 1% increase, I am likely to reduce work hours or cut marginal benefits (no free soup for you). For a 10% increase, I am more likely to consider the option of firing a worker or I may shift to a new technological set that reduces my demand for labor. It may happen rapidly or take some time, but there will eventually be an adjustment.
In any case, the minimum wage will imply some losses with a deadweight loss. Only the method by which it materializes is debatable. By definition, some people will be hurt and generally and even if supply is super-elastic (doubtful), some suppliers (workers) will be ejected from the market (or the quantity of labor they can supply will be ulitmately reduced). Since the minimum wage generally tends to fall on unskilled workers, this must be correlated with workers close to the poverty line.
Ideally, we’d need a measure of the minimum wage to be compared with the “at-risk” population over a long period of time in order to encapsulate all the effects of the minimum wage. The perfect measure is the “length of poverty spell” variable which has been emerging progressively from the BLS. The problem is that it is not broken down by state. Fortunately, Canada has that variable (well, a low-income variable which is a relatie poverty measure) for provinces. Inside the Survey of Labor and Income Dynamics (affectionally known as the SLID), this longitudinal variable has a span of eight years. Basically, we can know if a person has been below the low-income threshold for up to eight years. Let’s take that extreme measure and plot it against the minimum wage divided by the average wage.
As one can see from the scatter plot below, there is a more or less clear relationship between the minimum wage as a share of the average wage and the length of poverty spells. What is more impressive is that this graph is not a regression. More precisely, the provinces with the highest minimum wages (like my own province of Quebec and the province of Nova Scotia) also have the most extensive social welfare nets. Alberta, a province with the lowest minimum wage ratio and one of the least “generous” social welfare net in Canada, is at the very bottom of the pack in terms of the persistence of poverty.
I had a troubling encounter in the past few days. It was on Facebook and it was with a stranger. Here is how it went: I patronize several organizations’ and people’s Facebook pages, to stay informed and also to learn from them. There is a man, X, who is my Facebook “friend” and whose page I like because he is a libertarian, or a libertarian conservative like me, who knows useful things I don’t know. X has a talent for firing up debates on Facebook. In one debate a propos of I don’t remember what, one person, followed by several others, kept referring to the de-industrialization of America, its putative loss of manufacturing industries specifically.
I intervened calmly and politely to point out that there was no such thing. I remarked that the height of American industrial production was either 2008 or 2007, or maybe even 2006, not 1950 as they seemed to believe. I directed the debate participants to a couple of government sources. One woman responded almost insultingly, alleging that I was trying to send her on a wild goose chase. She appeared to think that I was referring her to the whole Census with its thousands of pages of documents. I took the trouble – obligingly, if I say so myself – to direct her through Facebook to a source I though was easy to read, NationMaster. In addition I summarized what NationMaster had to say on the topic.
Here is the summary: Continue reading
