Some of the opportunity costs, such as wages a firm pays its workers, are explicit. Other opportunity costs, such as the wages the firm owner gives up by working in the firm rather than taking another job are implicit. Economic profit takes both explicit and implicit costs into account, whereas accounting profits considers only explicit costs.A firms costs reflect its production process. A typical firms production function gets flatter as the quantity of an input increases, displaying the property of diminishing marginal product.
