The subject of the minimum wage is another perennial issue in politics, and much ink has been spilt on the topic.  One side favors raising the minimum wage as a means of increasing the income (and thereby bettering the livelihood) of the lowest paid workers, while the other opposes on the theory that higher minimum wages will result in higher prices and fewer employment opportunities (thereby worsening the lives of many).  A multitude of studies and calculations have been marshaled to favor each side, and as it is a complicated issue there is room for both sides to claim support for their cause.  Of course, basic economic doctrine teaches that price controls are counterproductive, which would in theory support the side that opposes minimum wage increases (or even the concept of a minimum wage at all), but there are a number of economists who hold that wages are a special case to which the laws of pricing do not apply.  As this series is not dedicated to in-depth dives but only to initial investigations into topics, I do not contend to settle this debate, but merely look at the surface of one aspect of it.

The question of the effect of mandatory wage increases on unemployment seems to me to be the most important facet of this discussion.  In my view, any job (and any salary) is better than no job (and no salary), so if increasing the minimum wage has a negative effect on employment that is enough for me to oppose it.  Of course, there are many variables that affect employment levels besides merely the minimum wage, and as it is impossible to run economic tests in controlled laboratory conditions it is impossible to break down exactly which variables affect it and to what degree.  But still, I feel that general trends can be seen in the data, and since unemployment is relatively low throughout the United States at the present time and there is a great variance in minimum wages among the states it seems like no better time than the present to look at a snapshot of the data.  And so I compared the minimum wage of each state (source) to the unemployment data from each state (source), graphed the data, and added a trend line.

From this simple analysis we find that there is a very weak positive correlation between increasing minimum wages and increasing unemployment.  The correlation is not strong enough to draw any definitive conclusions, but does seem to favor the interpretation that wage controls are akin to price controls, and thereby have a deleterious effect.  The trend line here implies an approximately 0.15% point increase in unemployment for every $1/hr raise in the minimum wage.  Raising the minimum wage from its current federally mandated rate of $7.25/hr to $15/hr, which is the most common current demand of the raise-the-wage faction, would thereby be estimated to increase unemployment by 1.16%.  This is actually in-line with estimates by the Congressional Budget Office (source) which predict that increasing the US minimum wage to $15/hr would reduce employment by 0.9%, putting 1.4 million workers out of a job.  In my view this means raising the minimum wage would do more harm then good.
