Conceptual Framework for this Course¶{.anchor-link}
- Information is costly
- Resources are either allocated by central planners (managers) or markets
- Different costs apply for different purposes
- What gets measured gets attention
- Incentives matter
Skills Focus¶{.anchor-link}
I want you to:
- be comfortable processing data to make recommendations and answer questions, and
- be excellent communicators in writing and in person.
So I am going to ask you to do these things often. But always in a friendly environment :) ::: ::: ::: ::: :::

Notes on evaluation:¶{.anchor-link}
- Homework that attempts to answer all parts of the problem will
get full credit.
- We will discuss the assignments in detail during the lecture after they are due.
- I will walk through how to address questions using both Python and Spreadsheets.
- In Class Participation: If you are here you will get full credit. You do not have to answer correctly, or answer at all if you do not want to. We will use iPRS to take attendance, along with spot checks.
- Exams: These will be pen/pencil and paper only. Minimal calculations so a computer will not be needed, but I will ask how you would set up a Jupyter Notebook or spreadsheet to answer the question. ::: ::: ::: ::: ::: :::

Topics in Management Accounting:¶{.anchor-link}
Cost Accounting Determining the cost of providing a service or product, of running a department, etc. This aspect of management accounting has the most overlap with financial accounting, providing the numbers for Inventory on the balance sheet and the Cost of Goods Sold on the income statement. Planning and Control Setting goals and quantifying them with budgets and standards. Comparing actual results to budgeted results and taking actions on the basis of this feedback. Remember that in Managerial Accounting "goals" and "budgets" are concrete plans not aspirations. Motivation Measuring and rewarding effort and innovation. Compensation and promotion often are contingent on performance as measured by management accounting procedures. ———————— —————————————————————————————————————————————————————————————————————————————————————————————– ::: ::: ::: ::: ::: :::

- Accounting is a systematic collection and processing of financial, as well as non-financial, data for decision-making.
- When firm managers are making the decisions this activity is Managerial Accounting
- When external investors making the decisions this activity is
Financial Accounting
- Financial Accounting only occurs when firms are public (or are going public) and required to provide audited financial statements to the public.[^1^](#fn1)
- Everything else is internal and therefore managerial.
- Much of the information is dual use (see Cost Accounting above).

The main difference is timing. Accrual accounting re-arranges cash flows so that revenues match the related expenses. Cost measures cash and non-cash resources sacrificed currently and in the future to achieve an objective. ::: ::: ::: ::: ::: :::

Inventoriable vs. Period Costs¶{.anchor-link}

::: {.jp-RenderedHTMLCommon .jp-RenderedMarkdown .jp-MarkdownOutput mime-type=”text/markdown”} For financial accounting purposes it is helpful to keep the following cost categories in mind:
Inventoriable Cost a cost that is directly associated with purchasing merchandise or manufacturing products that will later be sold. These costs are assigned to inventory as the units are being produced (or purchased) and awaiting sale. They enter the income statement (through the cost of goods sold) only when the units are sold. In this way, the cost of producing the units is matched directly against the revenue that is obtained from the sale of the units. Inventoriable costs are often called product costs. Period Costs a cost that is not directly associated with a product. They are generally viewed as costs of being in business for the period or costs that are too hard to match to the future revenues that they may help to produce. Period costs are expensed in the period with which they are associated. ———————- —————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————- ::: ::: ::: ::: ::: :::

Types of Inventoriable Costs for a Manufacturing Firm¶{.anchor-link}
Direct Material : All material costs that can be traced to a specific cost objective in a cost- effective manner. Direct Labor: All labor costs that can be traced to a specific cost objective in a cost- effective manner. Factory (Manufacturing) Overhead : All costs associated with manufacturing that cannot be traced to a specific objective in a cost-effective manner. Prime Cost : usually refers to direct materials plus direct labor costs Conversion Cost : usually refers to direct labor plus factory overhead costs ————————————– ——————————————————————————————————————- ::: ::: ::: ::: :::

Flow of Costs through the Manufacturing Process¶{.anchor-link}
Cost Object: an activity or item for which a measurement of costs is desired Cost Driver: any factor whose change leads to a change in costs Variable Cost: a cost that varies in direct proportion to changes in an underlying cost driver Fixed Cost: a cost that is not affected by changes in an underlying cost driver Average Cost: total cost divided by some measure of activity of a cost driver —————— ———————————————————————————
The most common measure of activity is units of production. In this case, average cost is also called unit cost. ::: ::: ::: ::: ::: :::

Costs and Decision Making¶{.anchor-link}

::: {.jp-RenderedHTMLCommon .jp-RenderedMarkdown .jp-MarkdownOutput mime-type=”text/markdown”} ———————— ———————————————————————————————————————————————————————————————————————————————————– Irrelevant Cost: A cost that is constant across, or unaffected by, the selection of a decision alternative. Differential Costs : Costs that change in response to a particular course of action. Sunk Cost : A cost item that has already been incurred and which is irreversible. For example, the purchase price of specialized machinery without an alternative use or material disposal value is a sunk cost. Opportunity Cost: The value of an asset in its best alternative use. If you use an asset to fulfill one objective, you forgo the opportunity to use the asset to fulfill other objectives. The opportunity cost is the value of the best of these forgone alternative uses. Controllable Cost: This term is often used in the context of performance evaluation. The idea is that a manager should be evaluated on, among other things, the costs that the manager can control or influence. ———————— ———————————————————————————————————————————————————————————————————————————————————– ::: ::: ::: ::: ::: ::: :::

- Individuals build and manage the systems that collect data and generate information
- Individuals are self interested

Linearity Assumption¶{.anchor-link}
Accountants often model the cost of producing $q$ units of output, $C(q)$ with the linear approximation:
$$ C(q) \approx \alpha + \beta q. $$
The approximation is regarded as sufficiently accurate in $q_1 \leq q \leq q_2$ for some $q_1$ and $q_2$. The interval defined by $q_1$ and $q_2$ is often referred to as the relevant range. The term $\alpha$ is the intercept of this approximation and $\beta$ is its slope. If the approximation is exact, then $\alpha$ is the fixed cost and $\beta$ is the per-unit variable cost (i.e., the marginal cost).
This assumption is powerful, and should be treated with care. ::: ::: ::: ::: ::: ::: ::: :::
