INFRASTRUCTURE PROVISION,POLITICS AND RELIGION: INSIGHTS FROM TUNISIA'S NEW DEMOCRACY

This paper analyzes the relationship between access to infrastructure services and support for religious parties based on the evidence produced by a recent democratic experience in Tunisia in which a religious political party, Ennahdha, governed from 2011 to 2014. The experience points to a complex relationship. In the 2011 election, areas with higher access are associated with higher support for Ennahdha than areas with lower access. In the 2014 election, however, infrastructure access is positively correlated with support for the party in areas where access had improved but negatively correlated with support for the party in areas that already had high access. A possible pragmatic general implication is that, to be politically competitive, religious parties, cannot bet solely on their religious commitment to provide basic services, including infrastructure, to the poor. They need to recognize the multiplicity of voter's concerns and their evolving agenda.     

Rate of Return Regulation: The Case of Spanish Ports

An original model is put forward in this article to explain and consider the behavior of some of the most important public services in Spain. The cost function approach and the input distance function approach are used to estimate the existence of overcapitalization as a result of rate of return regulation. The results show that overcapitalization generated by this regulation is too significant not to be taken into account.     

The significance of employee skill in flexible work organizations

Pressures for flexibility among enterprise employees have been explained in previous studies to be largely the result of exogenous factors driven by market pressures for improved product variety, quality and service. This paper derives new insights into the concept of flexibility based on the premise that manufacturing systems based on traditional hierarchical control have significantly given way to enterprise practices that stress a direct connection between employee skill enhancement, market outcomes and rewards. Through an analysis of the 1998 Workplace Employee Relations Survey (WER98) the study provides a more substantive explanation of the variables associated with flexibility, which have become significant in the transition process towards modern enterprise practices. Flexibility is demonstrated to be not only market driven but also dependent on endogenous factors directly promoted by management that stress workforce participation, collaborative working and multifaceted skills development. We provide empirical support for these arguments from an analysis of WERS98.

The determinants and impact of telecommunications reforms in developing countries

This paper has two related objectives. First, it seeks to identify the key determinants of some policies that have been at the heart of the reforms of the telecommunications industry in developing countries, namely, liberalization, privatization, and the (re)structuring of regulation. Second, it attempts to estimate the extent to which these policies have translated into actual deployment of telecommunications infrastructure. This simultaneous investigation is conducted by means of an econometric analysis of a 1985-1999 time-series-cross-sectional database on 86 developing countries. Sectoral as well as institutional and financial factors are found to be important determinants of the actual reforms implemented. We uncover a positive relationship between the decision to introduce competition in the digital cellular segment and the growth of the fixed-line segment, suggesting that these two segments have benefited from each other. We also find that countries facing increasing institutional risk and financial constraints are more likely to introduce competition in the digital cellular segment and to privatize the fixed-line incumbent, these policies being economically attractive to both investors and governments. In turn, these policies are those that enhance the deployment of fixed-line infrastructure. In contrast, competition in the analogue cellular segment and the creation of a separate regulator seem to be relatively less attractive policies as they are found to be less likely to be introduced in countries facing increasing institutional risk and budget constraints. Their impact on fixed network deployment is found to be negative or non significant.     

AN ANALYSIS OF ECONOMIC INFRASTRUCTURE INVESTMENT IN SOUTH AFRICA

This paper analyses long‐term trends in the development of South Africa's economic infrastructure and discusses their relationship with the country's long‐term economic growth. A database covering national accounts data, railways, roads, ports, air travel, phone lines and electricity was established for this purpose, and may facilitate further quantitative research. PSS (Pesaran, Shin and Smith, 1996, 2001) F‐tests are used to identify directions of association between economic infrastructure and economic growth. These indicate long‐run forcing relationships from public‐sector economic infrastructure investment and fixed capital stock to gross domestic product (GDP), from roads to GDP, and from GDP to a range of other types of infrastructure. There is also evidence of potential simultaneity between specific types of infrastructure and GDP. The evidence suggests three main findings. Firstly, the relationship between economic infrastructure and economic growth appears to run in both directions. Inadequate investment in infrastructure could create bottlenecks, and opportunities for promoting economic growth could be missed. Secondly, South Africa's stock of economic infrastructure has developed in phases. Policymakers should focus on choosing or encouraging the right type of infrastructure at the right time. Thirdly, the need for investment in economic infrastructure never goes away. The maintenance and expansion of infrastructure are important dimensions of supporting economic activity in a growing economy, provided that individual projects are chosen on the basis of appropriate cost‐benefit analyses.

Affordability of Household Water and Sewerage Services in Great Britain*

This paper analyses the problem of water affordability in Great Britain. The use and meaning of the term ‘affordability’ are discussed in relation to the domestic or household customers of the British water industry. Using microeconomic data from the Family Resources Survey, affordability is calibrated by income group and household composition for Scotland, England and Wales. Whilst measurement or calibration is the primary focus of the paper, the related question of the way in which an affordability threshold or benchmark might be established is considered. A critique of the various financial support mechanisms currently available to households encountering difficulties in paying water and sewerage charges is followed by a discussion of the policy implications of the research and the way in which it relates to the wider social inclusion agenda of central government.     

Competition and countervailing power: Evidence from the China Eastern and Shanghai Airlines merger

This paper examines the motives and effects behind the horizontal merger between China Eastern and Shanghai Airlines in 2009. We develop testable hypotheses, incorporating into a unified framework the two merging airlines, their domestic and international competitors, and relevant airports along the supply chain. We employ an event study methodology and show that domestic competitors gain whereas international competitors lose. Our results suggest that the sources of gain for the merging firms are market power in domestic markets and efficiency improvement in international markets. Further, as a hub for the merged airline, Shanghai Airport experienced positive abnormal returns. Our results do not support the hypothesis that the merged airline gains countervailing power towards airports. Our event study findings are robust to alternative estimation periods and samples, and are consistent with analyst forecasts and long-run operating performances.     

ECONOMIC INFRASTRUCTURE: A REVIEW OF DEFINITIONS, THEORY AND EMPIRICS

Infrastructure investment, especially in South Africa, is currently at the forefront of policy and public debate. But the term ‘infrastructure’ has a variety of definitions and interpretations; the reason for the various definitions is related to infrastructure's various impacts and incidence. Three levels of infrastructure are identified: local, national and transnational. Infrastructure at all three levels are subject to certain market failures which require some form of government intervention. Furthermore, theory postulates a number of benefits from infrastructure, both on economic growth and equity. Both the quantity (access to infrastructure) and quality (reliability of infrastructure or accompanying services) are important. Finally, empirical analysis tests whether these theoretical benefits are indeed realised. However, it seems as though infrastructure empirics are subject to a number of serious limitations.
