Title: Adopting Alternatives
1Adopting Alternatives
- A methodology for
- improved economic decision-making
- in enterprise management
2- Situation
- Agronomic research considers various production
methods and provides data and information about
how effective these alternative methods are. - Farm managers must decide, based on the
information available to them and their personal
preferences, whether or not to adopt a
recommended alternative practice. - Taking a rational, methodical approach to problem
solving leads to better economic decisions and
reduces the chance of an undesirable outcome.
3- The purpose of this presentation is to outline
the eight step process that better farm managers
use to make good economic decisions about whether
or not to modify an existing production practice
(the base plan) by adopting a proposed new
practice (an alternative plan). - This is an iterative process, comparing the base
plan to one alternative at a time.

5- Step 1
- Monitor the base plan
-
- identify a problem
-
6 Step 2 Consider all alternative solutions
(brain-storming)
7- Step 3
- Is the alternative compatible with this familys
values this farms goals? - Farmers will have different goals objectives,
even when their resources are similar, because
they have different values and/or feel more or
less strongly about each value.
8- Step 4
- Is a particular alternative technically
feasible? - Is the alternative practice or crop compatible
with local agronomic, climatic and other
physical growing conditions? - Does the managerial capacity exist on the farm to
implement the alternative? - Is the necessary labor and/or machinery available
to produce the product effectively?
9- Step 5
- Is the alternative economically feasible (more
profitable )? - For example, consider a farmer trying to decide
between his current practice of hand weeding and
the alternative of applying herbicide. His
current practice results in average yields of
2,000 kg/ha. However, researchers using
herbicides in on-farm trials obtained an average
yield of 2,400 kg/ha. Would it be more profitable
to adopt herbicide weed control? - To answer this question, we need a method to
organize experimental data about the costs and
benefits of various alternative treatments and to
enable us to compare the net benefits.
10- A complete budget or enterprise budget
calculates the profitability for a single
enterprise, such as maize or coffee production. - Unfortunately a complete budget requires that
one know all of the production costs for an
enterprise. Most farmers have never bothered to
collect the data and figure out how profitable
the enterprise actually is. - Fortunately, in order to compare the relative
profitability of two production practices, the
current base plan and the proposed alternative
plan, one need only compare those costs that
actually vary between the two methods of
production.
11- Marginal analysis
- A partial budget, as its name suggests, consists
only of those parts of two enterprise budgets
that are immediately relevant to the comparison
of the current base plan and an alternative. It
only considers - 1. the marginal revenue (i.e., extra revenue
any new revenue minus any revenue foregone)
and/or - 2. marginal costs (any new costs minus any
costs saved.) - The partial budget is therefore much easier to
work with than two complete budgets, and for the
purposes of evaluating a proposed alternative, a
partial budget is all we need.
12- Calculation of costs that vary
- Price for herbicide (/l.) 250
- Application rate (l./ha) 2 liters
- Cost of herbicide (/ha) 500
- Labor wage rate (/day) 50/day
- Time to apply herbicide (days/ha) 2 days
- Cost of labor apply herbicide (/ha) 100
-
- Labor wage rate (/day) 50/day
- Time for hand weeding 8 days
- Cost of labor for hand weeding 400
-

14- The partial budget is the most basic farm
management tool. - The partial budget can be used for a wide
variety of comparisons and should always be the
first tool to use in any comparative analysis. If
this tool is not up to the task at hand, one will
have to go on to a more complex tool, such as the
complete enterprise budget, or even to a
whole-farm budget, to solve the problem.
15- Marginal analysis (continued)
- The marginal (or extra) benefit from herbicide
use is clearly higher than for hand weeding.
There is a positive economic benefit from the
alternative, but it would be useful to have some
way to measure the relative profitability of the
alternative. -
- We could consider the rate of return to the
extra cash used to implement the alternative and
compare this rate to that available from other
uses of the money. We can calculate a marginal
rate of return using the alternatives marginal
cost (MC) and the resulting marginal benefit (MB).
16- In the weed control example the marginal revenue
(MR) is 720, the marginal cost (MC) is 200/ha.
(600 - 400) and the marginal benefit (MR-MC) is
520/ha. So for a cost of 200, one will receive
a marginal benefit of 520, or a net benefit of
320 (520 - initial 200). - A good way to assess the alternative is to
calculate the marginal rate of return (MRR) by
dividing the net benefit by the marginal cost, in
this case 320/200 1.60 . For every 1
invested the farmer will earn a 1.60 profit,
that is, a MRR of 160. -
- Farmers will not usually adopt a significant
change unless the marginal rate of return is
greater than 100. This rate of return must cover
the cost of money (interest) and all the
perceived risks of implementing the alternative.
17- Step 6
- Is the alternative financially feasible?
- Does this farmer have access to the extra cash
required to implement the alternative plan? - A cash flow budget is more useful than a partial
budget to determine financial feasibility. - Is the opportunity cost of the alternative too
high for this farmer?
18- Is the opportunity cost of implementation
personally too high for this farmer to adopt the
recommendation? -
- What is an opportunity cost?
-
- If you do one thing, you cannot do the other
thing. An opportunity cost is simply the value
of what one has to give up in order to adopt the
better alternative.
19Example B - Opportunity cost All coffee is
produced on new growth. Pruning coffee will
double the yield of unpruned coffee. In the
first year after pruning, there will be no crop.
In year 2 there will be half a crop Coffee
growing on new shoots (the same as before the
pruning). In year 3 and thereafter the crop will
be at least twice as much as before pruning.
20So, should a farmer prune or not? It is clearly
economic to adopt pruning. However, most Timor
Leste farmers do not prune because their cash
flow will not allow them to go for a whole year
without coffee income. The opportunity cost of
pruning is the lost coffee income of the first
post-pruning year. Government policy and banks
can be especially useful in making an
economically feasible alternative financially
feasible. Growers could implement the pruning
recommendation over a longer period of time to
reduce the impact on their cash flow.
21- Step 7
- Is the perceived risk of the alternative
acceptable to this farmer? - Risk refers to a situation in which more than
one possible outcome exists, - some of which may be unfavorable.
- Risk is the possibility of adversity or loss
risk refers to uncertainty that matters.
- Marginal analysis gave us some idea of the size
of the cushion that is available to absorb the
risk. - Break-even analysis is another way to calculate
the ability to absorb the inherent risk of the
alternative.
22- To determine the break-even point
- 1. Determine which one or two variables in the
partial budget are most likely to vary and cause
the plan to fail? -
- 2. For each of these variables calculate
how much short of the projection the alternative
can be and still have the farmer be no worse off
than he was with his base plan. In short, how
much extra benefit is necessary to cover the
extra costs incurred by implementing the
alternative.
23- In the earlier weed control example the
increased yield from using an herbicide and the
price for the crop may not turn out to be as high
as the farmer had hoped. But one way or another
the alternatives marginal cost (200) must be
covered. - Example C - Break-even yield
- The projected net market price of the product is
2.00, so the farmer will need to obtain at least
100 extra kg. (200/2) to cover his extra costs.
The break-even extra yield is 100 kg. Therefore,
the total break-even yield is 1900 kg. (1800
100), assuming the projected 2 price proves to
be correct.
24- Or lets assume the farmer does achieve the
2,160 kg. yield he had hoped for, but the price
drops. How far could it drop and still provide
enough revenue to cover the extra costs, that is,
what is his break-even price? - Example D - Break-even price
- We know he needs to make at least 3,800 (3,600
200) and we know his yield will be 2,160 kg.
Therefore, the break-even price is 3,800 2,160
kg. 1.76. - This means that the price could drop from 2.00
to 1.76 and the alternative would at least
break-even. (However, if the alternative were not
implemented and the net price dropped to 1.76,
the farmer would be substantially worse off. And
the alternative would then become that much more
attractive.)
25Sensitivity analysis
A simple, interactive Excel spreadsheet offers a
more sophisticated means of assessing risk
dynamically. It involves selecting the two
variables of most concern (often price and
yield) as the vertical and horizontal axis of a
five by five matrix. In each cell the marginal
benefit is displayed for the higher and lower
values of the selected variables. It is easy to
see how sensitive the alternatives benefits are
to variations in price and yield (or which ever
variables are selected.)
26Example E - Sensitivity analysis (using the
earlier herbicide alternative)
27-
- Other considerations How sensitive would the
success of this plan be to external variables not
considered in the partial budget? - E.g., drought or timing of rainfall, excess
rain at planting causing need to replant
28- Step 8
- Implement the alternative
- and monitor performance
- (esp. in comparison to original base plan).
