Production is a firm’s activity of converting a set of some objects (i.e., inputs) into different kinds of objects (i.e., outputs). In general, inputs are classified into two categories: intermediate goods and primary factors of production (production factors or, simply, factors). Intermediate goods are inputs to a production activity that themselves are the outputs of other production activities. On the other hand, primary factors are productive services provided by such things as labor, capital, and land that are not (considered to be) the outputs of other production activities (at least) within a certain period of time. We have to distinguish the productive services provided by a primary factor from the factor itself as a physical object that generates productive services. For example, when we refer to “capital” as a physical object, it means a stock variable such as machine tools, equipments, and factories, which are indeed the outputs of some production activities completed before the period of time we are concerned. On the other hand, when we refer to “capital” as a production factor, it means the workings or services generated by the physical capital and is considered as a flow variable defined for a certain period of time. ${ }^3$

Production function: Technology of producing a good is the entirety of firm’s knowledge of how to use and process inputs and how to organize and manage an appropriate system of production in order to obtain outputs efficiently. We can think of production technology as a certain relationship between possible combinations of inputs and the corresponding maximum outputs of the good. For simplicity, we often assume that inputs consist only of primary factors.

Suppose that there are $m$ primary factors indexed by $i=1,2, \ldots, m$. Let $v_i \in \mathbb{R}{+}$be the quantity of the ith primary factor (i.e., factor $i$ ). A combination of factor inputs, $v=\left(v_1, v_2, \ldots, v_m\right) \in \mathbb{R}{+}^m$, is called an input vector. Production technology of producing a certain good can be represented by a non-negative, real-valued function $F: \mathbb{R}{+}^m \rightarrow \mathbb{R}{+}$, which we call a production function:
$$F(v) \equiv F\left(v_1, v_2, \ldots, v_m\right),$$
which represents the maximum amount of the good obtained from putting an input vector $v$ into the production process under the current technology. We say that factor $i$ is indispensable in production if the good cannot be produced without factor $i$, that is, if $v_i=0$ implies $F\left(v_1, \ldots, v_i, \ldots, v_m\right)=0$
