An input whose quantity can be changed in the time period under consideration. The most common example of a variable input is labor. Variable inputs provide the means used by a firm to control short-run production. The alternative to variable input is fixed input. A fixed input, like capital, provides the capacity constraint in production. As larger quantities of a variable input, like labor, are added to a fixed input like capital, the variable input becomes less productive, which is the law of diminishing marginal returns.

The quiet, peaceful town of Shady Valley has always been a great place for a pedestrian to wander through the workings of the economy. I'm afraid, though, that it's about to end. I've been offered another job -- an opportunity to wander around the streets of the distant mecca of Shady Lane to search out the mysteries of plant pathology. In Shady Lane, the sidewalks are smoother, the crosswalks are better, and the pay is much more lucrative. However, in that Shady Lane is in another time zone and several states away, migration would be my last topic of the day. There's a lot to be gained from this potential relocation of my residence, but it's not without cost. While I ponder this decision, perhaps you can help out by considering the topic of migration.
