Labor and Capital

Tonight I visited a local fast food establishment to grab something on my way home from the college. In most respects this is a very typical establishment, but it normally stands out in one notable way. Rather than giving your drive-through order to a voice-box, you give your order to a live person standing by the menu board. And this is no temporary situation - there is almost always a person stationed outside by the menu.

Today the order-taker was, as usual, stationed outside. Additionally there was a second employee outside, running up and down the lane, taking money/credit cards, giving the payment to the teller inside, and returning change/cards to each vehicle. I'm not sure why the manager chose to do this (pay a second employee to collect payments), but let's take a brief look at the economics in play.

Any producer must make a wise choice between investing in capital (equipment, machines, etc...), labor (manpower), or some combination of the two. Both are usually necessary for the production of goods or services. At the local fast-food establishment, the manager made a choice between upgrading his order-processing equipment and paying additional people. The producer (the manager in this case) will typically make the choice based on a comparison of cost and productivity for each additional unit of labor or capital.

From what I observed today, I can only conclude that the local manager believes that it is better (leading to greater net profit) to hire two additional people beyond what similar establishments usually employ than to upgrade the capital. In this case "capital" may include capability of the person working the registrar (who usually handles orders and taking payment as well). Therefore, because most fast-food establishments choose the capital route, I must conclude that either the capital improvements are for some reason unavailable or that labor is particularly cheap for this particular manager.
