CD | R Documentation |

This function returns the awards vector assigned by the concede-and-divide (CD) rule to a two-claimant problem.

CD(E, d, name = FALSE)

`E` |
The endowment. |

`d` |
The vector of two claims. |

`name` |
A logical value. |

Let *E≥ 0* be the endowment to be divided and *
d=(d1,d2)* the vector of claims
with *d≥ 0* and such that the sum of the two claims exceeds the endowment *d1+d2≥ E*.

The concede-and-divide rule first assigns to each of the two claimants the difference between the endowment and the other agent’s claim (or 0 if this difference is negative), and divides the remainder equally.

*CD1(E,d) = max{E-d2,0} + 1/2(E-max{E-d1,0}-max{E-d2,0})*

*CD2(E,d) = max{E-d1,0} + 1/2(E-max{E-d1,0}-max{E-d2,0})*

Several rules are extensions of the concede-and-divide rule to general populations: AA, APRO, MO, RA, and Talmud.

The awards vector selected by the CD rule. If name = TRUE, the name of the function (CD) as a character string.
