Investment in Next Generation Networks and the Role of Regulation: A Real Option Approach



4.2 - Model outcome and the role of regulation

As already said, we follow the Cox et al. (1979) model to investigate the impact of
different regulatory regimes onto NGN investment decisions. Its outcomes include
expected optimal investment timing and optimal investment policy (i.e. critical values)26.
Since the timing of the investment is of particular interest to policy makers and to national
sectors regulators, we will focus on the interval between when the investment opportunity
arises and when the investment is expected to be undertaken, named
fugit. The central
results of the simulations for the input data shown in Tables 1 and 2 are represented in
Figure 10.

For the sake of simplicity we divide the project lifespan into three phases. The first
phase includes the first six years of the project lifespan, which we define as the “volatile”
phase. The second phase (the “steady” phase) embraces years from the seven to the twelve,
while the third phase (the “terminal” one) includes the remaining years of the project
lifespan (from the thirteen to infinity). Differently from the steady and the terminal phases,
to refrain from the irreversible decision entails an insurance value in the volatile one.

26 Critical values can be used to determine the optimal subsidy i.e. the artificial increase of the NPV (either in
absolute term or expressed as a percentage) enabling a change of the today optimal policy outcome from
“delay the investment” to “invest now”.
