Uncertain Productivity Growth
3 THE OPTIMAL MARKET ENTRY MODE
level ^Fc will be always equal to or below r∂*Ec. Consequently, for such cost constellations FDI
represents the only and optimal market entry strategy conditional on positive net present values.
It is possible to derive a concise condition which describes the ordinal rank between the two
productivity cut-offs. It can be shown that

Within the assumed relative cost structure, relation (21) states that the export mode’s produc-
tivity cut-off ^Ec is smaller (equal, bigger) than the FDI productivity cut-off tf*Fc if its fixed cost
advantage is bigger (equal, smaller) than the FDI mode’s variable cost advantage. Since within

ative cost box. The diagonal curve in Figure 4 represents all relative cost constellations for the
FDI and export mode which exhibit a comparative fixed cost advantage equal to the compara-
tive variable cost advantage, given the technology concavity θ and the country specific degree of
competition ν . Therefore, any relative cost structure on or above the diagonal line leads to a
FDI productivity cut-off ∣)iFc being equal to or bigger than ∣)iEc. In both cases the FDI mode’s
