For Whom is MAI? A theoretical Perspective on Multilateral Agreements on Investments



A Appendix

A.1 Appendix 1. Proof of Lemma 1.

From the definition of ? we have

μ ⅛ ) ? (ɪ - ?)=( p )(? - °χι - ?+°).        (15)

Next, from the partial derivatives of expected countries’ income with respect to
?
h at given z and p

@EZ yh
@?h
@E-Z yh
@?h


0.5 (zp) (ɪ - 2?h + 2°) ;                  (16)

0∙5 (1≡7) (ɪ - 2?h) ;                (17)

we can establish that @E--Z yh@EZ yh if and only if
@Ph        @fih               j

(? - °)- ? + °) (ɪ - 2?h) < ? (ɪ - ?) (ɪ - 2?h + 2°) ;     (18)

where (15) has been used in (16) and (17). Inequality (18) is clearly satisfied,
since ?<0.5 and ?
h < 0.5 for all h. The result of Lemma 1 follows directly
from (15) and (18).

A.2 Appendix 2: Proof of Lemma 2.

Using (8) and developing integrals the difference ¢E = EZ¼ - EZ¼ can be
evaluated as follows:

-5 + 18° + 12°2 + ?(2 - 12° - 4?l) + 12?i - 4?2
¢^ =------------------------------------

;         (19)

where ?l ? 0.5. It is easily checked that the value ?* that equates to zero
¢E is given by

15 - 18° - 12°2 - 12?l + 4?2

(20)


2 ɪ - - 2?l

One can see from (20) that ?* as a function of ° has an asymptote in ° =
0:5-f9l ´ °*. Moreover, ɪ- = 61 3'9l+2'9l+6° +4fl° 2°0 in the admissible
3        °                , @°               (1--l)2         —

range of ?l and °, so that lim ?* = +ι, and lim ?* = -1. Since, when ° = 0,
°!°*-             °!°* +

?* is always higher than 1=2, we necessarily have that ?* > 1=2 for ° < °*.
