1. The production function(x = sacks sown in year 1, E(x) = expectedexpected sacks of wheat to be harvested in year 2):
2. Farmer 1 has 4040 sacks of seed available.
3. Due to the bad harvest Farmer 2 has only 2020 sacks at his disposal.
Can bothboth farmers be made better off by entering a (sort of) “financing contract”?

Year 2: Finding the optimum reallocation

Reason behind this recommendation:The 60th sack’ marginal productmarginal product is much highermuch higher when sown on field 2field 2. Thus, the sack should be reallocated to field 2.

In analogyanalogy to the reasoning forthe 60th sack, the 59th and the58th should be sown on field 2.

400A possible misunderstanding?
In the constellation here investigated, the two farmers should divide up the total amount of sacks available into equal shares.Reason: By assumption they share the same production function.
In contrast, when one of the farmers is more productive, the optimal allocation should then favor him accordingly with a higher share.

Farmer 1 has 4040 sacks of seed available.
Farmer 2 has 2020 sacks only at his disposal.
How can bothboth of them be made better off?
In order to maximize total output, Farmer 1 should transfer some 10 sacks10 sacks of seed to Farmer 2.

Year 2: Determining the conditions of reallocation
If Farmer 1Farmer 1 keeps all 40 sacksall 40 sacks to himself, he can expect to harvest:
If Farmer 1 transfers 10 sacks10 sacks to Farmer 2Farmer 2, he is still able to harvest by sowing the remaining 30 sacks (on average):
Thus, in order to make the transfer attractiveattractive to Farmer 1, he must at leastat least be compensated by:

Year 2: Determining the conditions of reallocation
If Farmer 2 only sows his ownown 2020 sacks, he can expect to harvest in year 2:
By receiving 10 additional sacksreceiving 10 additional sacks from Farmer 1 in year 1, for Farmer 2 the total output in year 2 is expected to increase to:
Thus, in comparison to a situation without support by Farmer 1, Farmer 2 increasesincreases his expected output by:
After paying at least 25.42 sacks to farmer 1 in year 2 (as a compensation for receiving 10 sacks in year 1), Farmer 2 expects to keep hold of an additional yieldadditional yield of:

Conclusion
Thus, we have shown how – when external sources are employed to “support” investment projects – bothboth sides …
Because financiers could always use their assets in their own projects instead of supporting external projects, they must be compensated for providing resources (opportunity costopportunity cost).
• Farmer 1 = party A: “The external source” = FinancierFinancier
• Farmer 2 = party B: “The original investorinvestor”… can be made better off.

Conclusion
Two basic typesbasic types of compensation:
Contract version A: The financier becomes a “partner in investment”. By this she / he acquires a claim on the project’s surplus proportional
to his / her share of investment. Equity CapitalEquity Capital
Contract version B: The financier is compensated by an ex ante determined fixed amount (exception: case of bankruptcy). No further
claims beyond this level of compensation do exist. Debt CapitalDebt Capital
