Libéralisation des Services publics de réseau et jeux croisés de la régulation: le cas de l'électricité

This article analyses the liberalization of public services with a special focus on the (re)regulation process that is induced. Firstly, a conceptual framework is developed in order to identify the constitutive elements of the public regulation related to market competition, public service obligations, operators and public property, as well as the tension between them. Secondly, a comparative study describes the liberalization and the regulatory design of the electricity sector in England, France, Germany, Norway and Switzerland. As a conclusion, we note the necessity to further analyse the introduction of market mechanisms into formerly monopolistic network industries and its effects.     

POLITICAL ECONOMY OF SERVICE TRADE LIBERALIZATION AND THE DOHA ROUND*

Abstract.   In this paper we examine political economic issues of service trade liberalization of a developing country in the context of the Doha Round negotiations. We first discuss the various unique characteristics of the service industries. Then we incorporate these features in a Grossman-Helpman style political economy model and solve for the politically-determined service sector protection. We then examine how various factors such as increased cross-cutting lobbying, the reduction of state-owned service providers and linking negotiation on agricultural protection with negotiation on service sector liberalization can help reduce the political constraints on liberalizing the service sectors.     

The impact of regulatory change on EU energy utility returns: the three liberalization packages

The European Union’s (EU) energy sector is changing due to major policy reforms. In this article, we examine the impact of major legislative changes which were designed to induce competition in the energy sector: the three liberalization packages. Competition was expected to benefit the industry by phasing out inefficient firms. EU citizens were also expected to benefit as competition was likely to promote a more efficient energy sector and more consumer choice of energy products and services. However, this legislative change occurred during a period of extreme market turmoil. We examine the impact of all these changes on the risk profile of the sector. Our results show that the liberalization legislation significantly increased systematic risk exposure of the sector, reducing its role as a defensive investment asset. We also show that commodities had relatively little impact on sector returns, but this was expected as utilities can offset commodity risk in hedging markets. We compare our results to those obtained in neighbouring EU sectors and find the impacts are isolated to the energy sector. This article makes a major contribution to energy policy by empirically showing the change in risk as a result of sector liberalization.     

Wage bargaining,trade and growth

We construct a North-South product-cycle model of trade with fully-endogenous growth and union wage bargaining. Economic growth is driven by Northern entrepreneurs who conduct R&D to innovate higher quality products. Northern production technologies can leak to the South upon successful imitation. The North has two sectors: a tradable industrial goods sector (manufacturing) where wages are determined via a bargaining process and a non-tradable sector (services) where wages are flexible. The South has only a tradable industrial goods sector where wages are flexible.We find that unilateral Northern trade liberalization, in the form of lower Northern tariffs on industrial goods, increases the rate of innovation but decreases both the bargained wage in the industrial sector and the flexible wage in the service sector. The wage effects are relative to the Southern wage rate. We also consider a variant of the model with Northern unemployment, driven by a binding minimum wage in the non-tradable service sector. In this case, Northern tariff cuts decrease the innovation rate and the bargained wage rate. In addition, the Northern unemployment rate increases. The model thus highlights the role of labor market institutions in determining the growth and labor market effects of tariff reductions. We also study the effects of unilateral Southern trade liberalization.     

The sequencing of reform policies in China's agricultural transition*

This paper provides evidence regarding gains due to agricultural market liberalization in China. We empirically identify the different effects that incentive and farm restructuring reforms and gradual market liberalization have on China's agricultural economy during its transition period. We find that average gains within the agricultural sector due to reforms that improved incentives and increased decision‐making authority of producers exceed gains due to market liberalization by a large margin. Our method of analyzing the effects of transition policies on economic performance can be generalized to other reform paths in other transition economies.     

Modeling services liberalization: The case of Kenya

This paper employs a 55 sector small open economy computable general equilibrium model of the Kenyan economy to assess the impact of the liberalization of regulatory barriers against foreign and domestic business service providers in Kenya. The model incorporates foreign direct investment in business services and productivity effects in imperfectly competitive goods and services markets endogenously, through a Dixit–Stiglitz framework. The ad valorem equivalent of barriers to foreign direct investment have been estimated based on detailed questionnaires completed by specialists in Kenya. We estimate very substantial gains to Kenya from regulatory liberalization in business services, and additional gains from uniform tariffs. The estimated gains increase to 50% of consumption in the long run steady state model, where the impact on the accumulation of capital from an improvement in the productivity of capital is taken into account. Decomposition exercises reveal that the largest gains to Kenya will derive from liberalization of costly regulatory barriers that are non-discriminatory in their impacts between Kenyan and multinational service providers.     

CREATION OF A SEPARATE TELECOM REGULATORY AGENCY: A DURATION ANALYSIS OF ITS TIME PATTERN

At the center of the issues set out in the 1997 WTO Agreement on Basic Telecommunication Services was the creation of separate telecom regulatory agencies. Using the Cox proportional hazards model, this study examines how a country's socioeconomic factors affect the country's incentive to reorganize its regulatory structure and create a separate telecom regulatory agency. The main empirical findings suggest that a country's incentive to institute a separate telecom regulatory body is greater when its telecom sector performance is relatively poor and its political environment is more competitive with few institutional barriers.

Regulatory reform in telecommunications in Central and Eastern Europe

In this paper we discuss public policy towards the telecommunications sector in Central and Eastern Europe (CEE), focusing primarily on the need to ensure adequate capital investment. The analysis falls into two main parts: the regulation of monopoly, and policy on liberalization. Concerning regulation, we discuss how policy credibility is likely to be a problem in the region, and how reputational considerations, the design of regulatory institutions, and methods of price control can help to ameliorate this problem. Concerning liberalization, we consider the effects of potential competition on investment incentives, and construct a simple model to analyse the different effects of liberalization and regulatory risk on investment. Some preliminary policy conclusions are drawn, and we argue that in the CEE region – in contrast to more well developed countries – a reasonable case can be made for allowing a temporary period of monopoly for basic services.     

The Effect of Foreign Entry Regulation on Downstream Productivity: Microeconomic Evidence from China*

We examine the cross‐industry influence of foreign entry regulation (based on a novel measure) on the productivity outcomes of downstream firms through input–output linkages in China. In contrast to the significant liberalization of the manufacturing sector, restrictions on the service sector remained stringent over the period 1997–2007. We find a powerful depressant effect of foreign entry barriers imposed on the upstream manufacturing and service industries on the productivity of downstream manufacturers, and this effect depends on a number of industry‐ and firm‐specific features. Our research calls for further investment liberalization (particularly in the service sector) in China.     

Impact of Market‐based Policies and External Fiscal Discipline on Ghana's Inflation

This study investigates the impact of liberalization of the forex exchange and financial sectors and external prudent fiscal management in Côte d'Ivoire on Ghana's inflation. We find that, in the financial sector, there is a case for liberalization, in terms of lowering inflation. However, a quasi‐liberalized system in the sector proves to have a greater potential to reduce inflation in Ghana. In the exchange market, non‐liberalization has the edge over liberalization in reducing inflation in Ghana. However, a quasi‐liberalized system in the sector has a greater potential to lower inflation. There is evidence of a strong intra‐continental transfer of inflation from Côte d'Ivoire to Ghana, but this transmission has been significantly moderated downwards by the implementation of prudent fiscal management in Côte d'Ivoire. We also find that monetary targeting and inflation targeting have deflationary effects, but we cannot claim that this has significantly reduced inflation. The implication of the result is that; a system that achieves the correct balance between the market mechanism and command system in the exchange and financial sectors has a greater potential to lower inflation in Ghana. Also, domestic monetary policies should not only be anchored on internal factors.     

A duration analysis of privatization in the telecom sector

The paper attempts to identify the telecom-sector performance indicators, relevant economic variables, and institutional characteristics of a country that effect the process of privatization of state-owned telecom enterprises. Using standard duration analysis of a panel data, we demonstrate that the privatization incentives are not only shaped by the mobility of financial capital in a country but are also influenced by the degree of competitiveness of private sector participation in policy-making process. The empirical results also reveal the significant impact of productive efficiency in telecom service provision on its course to privatization. We thank an anonymous referee for helpful comments and suggestions. We are solely responsible for all mistakes.     

Telecommunications Reforms In Malaysia

The article examines the range and scope of physical and structural changes that have taken place in the telecommunications sector in Malaysia in the past 15 years. It reviews the main policy reforms that have shaped the sector, including corporatization and privatization, and liberalization in fixed line and cellular services. The article documents the increase in competition, particularly in the cellular phone service market. Major regulatory reforms were introduced in the 1990s with the passage of the Communications and Multimedia Act and the establishment of the Malaysia Communications and Multimedia Commission. The key principles for regulating the sector are reviewed, including those directed towards economic regulation and consumer protection. With the absence of a formal competition law in Malaysia, the onus for addressing competition issues in the telecommunications sector rests with the sectoral regulator.     

Reassessing the productivity gains from trade liberalization

This paper reassesses the impact of trade liberalization on productivity. We build a new, unique database of effective tariff rates at the country‐industry level for a broad range of countries over the past two decades. We then explore both the direct effect of liberalization in the sector considered, as well as its indirect impact in downstream industries via input linkages. Our findings point to a dominant role of the indirect input market channel in fostering productivity gains. A 1 percentage point decline in input tariffs is estimated to increase total factor productivity by about 2 percent in the sector considered. For advanced economies, the implied potential productivity gains from fully eliminating remaining tariffs are estimated at around 1 percent, on average, which do not factor in the presumably larger gains from removing existing non‐tariff barriers. Finally, we find suggestive evidence of complementarities between trade and FDI liberalization in boosting productivity. This calls for a broad liberalization agenda that cuts across different areas.     

The effect of financial liberalization on banking sector stability

Several studies indicate that financial liberalization increases likelihood of a financial crisis without distinguishing between a normal period, unstable period preceding the onset of banking panics and crisis/post period. We explain in this paper the relationship between financial liberalization and banking sector vulnerability. Then, we argue that banking sector turmoil is most likely to occur after an intermediate degree of liberalization. Using a recently updated dataset for financial reforms, we find an inverted U-shaped relationship between liberalization and the likelihood of banking crisis for a sample of 49 countries between 1980 and 2010. We used a multinomial logit model in order to take into account what is called the ‘post crisis bias’. We ask whether the relationship remains when institutional characteristics of countries and dynamic effects of liberalization are considered. The empirical results indicate that the relationship between liberalization and banking sector stability depends strongly on the strength of capital regulation and supervision. With very weak regulation and supervision, the probability of banking crises is increasing with liberalization but this relationship is reversed as regulation and supervision become significant. The most important type of liberalization in relation to banking crises seems to be operational. A policy implication is that positive growth effects of liberalization can be achieved without increasing the risk of a banking fragility if appropriate institutions are developed.

Structure and performance of the service sector in transition economies1

This paper examines the performance of the service sector in the Eastern European transition economies during the 1997–2004 period. The performance of the service sector as a whole and of its sub‐sectors is very heterogeneous within the region. Service sub‐sectors that are information and communications technology producers or users and those using skilled labour more intensively exhibit the highest labour productivity growth. Our estimates show a positive and significant effect of liberalization on service labour productivity growth that is stronger for sub‐sectors that are more distant from the technological frontier. Service liberalization is also shown to have a positive effect on labour productivity levels and growth of downstream manufacturing industries.     

Multi-product firms,heterogeneous quality and exporting behaviour: product-level evidence from the movie industry

This article examines how quality affects heterogeneous multiple-product firms’ exporting behaviours. We develop a structural model of the global movie market, including both consumers’ movie demand choices and firms’ exporting decisions. A movie studio is a multi-product firm that releases many movies within a year. We model movie quality as a combination of firm-level appeal and product-level attractiveness. We find that both studio-level and movie-level heterogeneity affect demand for movie, and movie-level heterogeneity is relatively more important. We also explore the counterfactual effects of quality improvement and trade liberalization on trade. Our results show that improvement of quality increases both intensive margin and extensive margin of trade. By elimination of quota, we find that trade liberalization increases movie exports to a foreign market by 19%. The results of our study can also help improve understanding of trade in the service industry. For instance, we do not find a positive correlation between the foreign entry costs and the geographic distance, as in the case of manufacture goods.     

Quantifying the impact of services liberalization in a developing country

We compare goods versus services liberalization in terms of welfare, outputs, and factor prices in Tunisia using a CGE model with multiple products, services and trading partners. Restraints on services trade involve both cross-border supply (tariff-equivalent price wedges) and on foreign ownership (monopoly-rent distortions and inefficiency costs). Goods-trade liberalization yields a modest gain in aggregate welfare. Reducing service barriers generate relatively large welfare gains and low adjustment costs. Services liberalization increases economic activity in all sectors and raise the real returns to both capital and labor. The results point to the potential importance of deregulating services provision for economic development.
