The paper “Do regulatory reform dynamics matter for telecom sector performance. Evidence from MENA countries” (Cambini, C., Staropoli, C., Ahmed Ezzat, R.) was awarded as best paper (ex aequo) at the 4th Conference on the Regulation of Infrastructures (12 June 2015).

ABSTRACT

Motivation and Aim

In retrospect (more than two decades), we should be able to have a better view on how to proceed to de- and re-regulate, privatize and liberalize network industries. Notably, what is the appropriate dynamics of regulatory reforms?

No consensus emerges yet. Typically, on one hand, the OECD stated that “one core element in any reform package is the introduction of fair rules of the game in a newly privatized market for public services including the establishment of independent, competent and credible ad hoc institutions”(Goldstein 2002). On the other hand, Wallsten (2003) explained that the privatization of large monopolies prior to the implementation of a regulator has been a key element for the success of the reform since it helps facilitating competition. Indeed, some governments sometimes have given exclusivity periods to the privatized monopolies, so, they can make higher profits through efficiency gains before introducing competition. Traditionally, an independent regulator is seen as a way to increase efficiency of the incumbent monopoly prior (or even simultaneously) to its privatization in order to “avoid opportunistic behavior and to serve as a guarantee for investors against the risk of expropriation” (Spiller, 1993). But, evidences showed that it has not been applied in all countries. For instance, in our sample of MENA countries, introducing privatization before the establishment of IRA took place in: Bahrain, Qatar, Sudan and United Arab Emirates.

From an empirical point of view, almost no paper has addressed this issue of the optimal dynamics of reform and its impact on the industry performances. According to our knowledge, only Wallsten (2003) and Fink et al. (2003) explored those dimensions. Thus, this paper is a first attempt to test the effect of telecom reform sequences on sector performance in MENA countries, as a group of developing countries.

Methodology

To test the effect of reform sequences on telecom performance, we use a panel dataset of 17 MENA developing countries from 1995 to 2010 for the voice market in fixed and mobile segments. We estimate the model by IV-2SLS (Instrumental Variable – Two Stages Least Squares) estimation procedure while accounting for the endogeneity of reform policies. Telecom reform sequences include: Regulation-Privatization and Regulation-Competition sequences[1]. And the telecom performance has four dimensions: access, affordability, productivity and quality. The regression takes the form:

Y_it= β₀+ β₁R_it + β₂X_it+ Z_t + u_it

Where Y_it is one of the performance indicators we have chosen to consider.R_itis the reform variables and the reform sequences variables. X_it is a vector of control variables (GDP per capita and Population density), Z_tare year dummies and u_itis the disturbance term. The equation is estimated for each of the dependent variables we consider here.

In fact, the reform sequences are far from being exogenous. For instance, the level of performance in place could shape the sequence by which different reforms are introduced in the market. Thus, our analysis deals with this problem by endogenizing different reform policies and reform sequences variables by institutional, economic and political determinants. Namely, the instrumental variables we use are: the democracy indicator, the legal origin, natural resources rents as % of GDP and the independence year.

Preliminary results

According to our preliminary findings, the establishment of IRA has higher impact on the performance indicators when the dynamics is taken explicitly into consideration. The pre-existence of an IRA, prior to privatization and competition, matters. Such results are of great importance for policy makers in MENA developing countries, since it confirms that setting the rules for the regulatory framework is a priority; and the main concern for policy makers should be the guarantee of its credibility and effectiveness. Thus, it should be able to encourage new entrants and positively impact the sector performance.

Focusing on the Regulation-Privatization sequence, we find that, although the privatization alone has a negative effect on the fixed access, this sequence helps eliminating the negative effect of privatization on the fixed access. Thus, an IRA provides investors with credibility and confidence before entering the market. Also, it is important since a regulator in place mitigates the harmful effects of exclusivity periods and serves as a guarantee that the privatized incumbent would not restrict output if it not is profitable for him. However, the prior existence of a regulator leads to an increase in fixed prices, which implies that the prices would remain high due to privatizing the incumbent operator. Although this effect has a negative impact on consumers, IRA would give incentives for investors to enter the market by increasing prices.

The sequence between regulation and competition has no significant effect on the access, so, the prior existence of IRA is not efficient in setting the rules that would facilitate the entry of new competitors in the market such as interconnection agreements, licensing conditions… Moreover, the prior existence of a regulator seems to reduce telecom productivity. This negative effect may suggest some regulatory capture phenomena. Thus, these results reflect the importance of institutions to set the market rules since the incumbent can represent a high barrier for new entrants by preventing interconnection, by adopting vertical price squeezing or by capturing the regulator in place. It is obvious that without an IRA, no incumbent operator would allow competition, since it would not be profitable for him; however, IRA efficiency needs to be more improved.

[1] Concerning the third sequence of privatization and competition, no country in our sample introduced competition in the fixed segment before the privatization of its incumbent operator. Thus, the effect of such variable could not be statistically tested.
