List as many types of cost as you can think of that might affect the cost (or cost-based price) of milk

Session 5: Cost Standards and their Application
Examples of cost categories
6
Production costs: Land, cows, feed,
fertilisers, labour
Distribution costs: Transport, packaging,
refrigeration, logistics
Retail costs: Shops, staffing,
marketing, branding, billing
Processing costs: Equipment and
labour for milking, pasteurising, skimming

HIPSSA Cost model training workshop:
Session 5: Cost Standards and their Application
Four key types of cost
•Cost which must be incurred if any non-zero quantity is supplied
Fixed costs
• Cost whose magnitude changes when output changes
Variable costs
• Assets purchased for use in more than one year
Capital costs
• Costs consumed entirely within the current year
Operating expenditure

Possible categorisation of the costs of milk supply
The extent to which costs are fixed or variable depends on the time horizon. Economists define the long run as the shortest period of time necessary for all the fixed costs to become variable.

HIPSSA Cost model training workshop:
Session 5: Cost Standards and their Application
How each cost type is treated in cost models
Fixed costs
Excluded from marginal and incremental cost calculations
Variable costs
Part of all cost standards, but may be treated differently
Capital costs
Need to be annualised for pricing: different approaches apply
Operating expenditure
May be direct or joint/common. The latter may be excluded depending on the mark-up regime.

HIPSSA Cost model training workshop:
Session 5: Cost Standards and their Application
Four key cost standards
Fully Allocated Costs (FAC)
An accounting method to distribute all costs among a firm's various products and services
Long Run Incremental Costs (LRIC)
An accounting method to calculate the cost caused by the provisioning additional units (the “increment”) or by an extension of the service portfolio
Stand Alone Costs
The costs of supply assuming a firm only provides one service
Marginal Costs
Cost caused by the provisioning of one additional unit of service

HIPSSA Cost model training workshop:
Session 5: Cost Standards and their Application
13
Fully Allocated Costs (FAC)
All costs have to be taken into account and allocated to the products and services of a company
The concept is neutral with regard to valuation principles, depreciation and cost of capital calculation methods
The art of fully allocated costs is to identify direct cost, joint (service family) cost and common cost and to find ways to properly allocate the latter two categories to services.
Can be used with either historic costs (actual costs incurred) or current costs (revalue assets at their replacement costs)
![Page 14: International Telecommunication Union HIPSSA Cost model training workshop: Session 5: Cost Standards and their Application EXPERT LEVEL TRAINING ON TELECOM.](https://reader035.fdocuments.us/reader035/viewer/2022062619/5518ae46550346a61f8b4dc0/html5/thumbnails/14.jpg)
HIPSSA Cost model training workshop:
Session 5: Cost Standards and their Application
14
Long Run Incremental Costs (LRIC)
Estimates the incremental cost of providing the service under consideration
Defined as the total cost when the service is provided less the cost when the service is not provided
By measuring over the long run, infrastructure investment is variable rather than fixed and can be matched to capacity
If common costs are to be recovered, then a mark-up is required
LRIC typically uses current or forward looking costs (cost of an efficient firm using new infrastructure)

Direct cost or directly attributable cost costs are incurred as a direct result of the provision of a particular
service. can be fixed or variable.
Joint or shared cost (indirectly attributable cost) The cost of inputs that contribute to the production of two (or more)
different increments. For example the costs of mobile towers contribute to 2G and 3G
services (and maybe others) Costs can be allocated on the basis of identifiable cost drivers (e.g.
tower space)
Common cost inputs necessary to produce several services, which cannot be directly
assigned to specific services.

HIPSSA Cost model training workshop:
Session 5: Cost Standards and their Application
29
Emerging best practice
Constant mark-up same percentage to all services
Efficient Component Pricing Rule (ECPR) based on opportunity cost - considers retail prices only works well if retail prices already competitively priced
Ramsey Pricing sets mark-ups inversely proportional to the price elasticity of
demand theoretically works well, but very difficult to implement
Floors and Ceilings allows the operator flexibility of assigning mark-ups within
limits (generally defined as between MC and SAC)

The aim of cost based regulation
Aim is to encourage economically efficient investment to promote the long term interests of end users
Balance between: efficient use of existing infrastructure investment in new infrastructure by incumbents and new
entrants
Regulation of interconnect services is required where there is potential market failure
Without infrastructure based competition - ongoing regulation will be necessary
![Page 31: International Telecommunication Union HIPSSA Cost model training workshop: Session 5: Cost Standards and their Application EXPERT LEVEL TRAINING ON TELECOM.](https://reader035.fdocuments.us/reader035/viewer/2022062619/5518ae46550346a61f8b4dc0/html5/thumbnails/31.jpg)
