It derives from the Pennsylvania Dutch superstition that if a groundhog emerging from its burrow on this day sees its shadow due to clear weather, it will retreat to its den and winter will persist for six more weeks; if it does not see its shadow because of cloudiness, spring will arrive early. While the tradition remains popular in modern times, studies have found no consistent correlation between a groundhog seeing its shadow and the subsequent arrival time of spring-like weather.

We first estimate the effect of the minimum wage increase on employment changes by wage bins throughout the hourly wage distribution.

We find that the overall number of low-wage jobs remained essentially unchanged over the five years following the increase.
