Services trade and growth
The competitiveness of firms in open economies is increasingly determined by access to low-cost and high-quality producer services - telecommunications, transport and distribution services, financial intermediation, etc. This paper discusses the role of services in economic growth, focusing in particular on channels through which openness to trade in services may increase productivity at the level of the economy as a whole, industries and the firm. The authors explore what recent empirical work suggests could be done to enhance comparative advantage in the production and export of services and how to design policy reforms to open services markets to greater foreign participation in a way that ensures not just greater efficiency but also greater equity in terms of access to services.Economic Theory&Research,Banks&Banking Reform,Transport Economics Policy&Planning,ICT Policy and Strategies,Emerging Markets
Landlocked or policy locked ? how services trade protection deepens economic isolation
A new cross-country database on services policy reveals a perverse pattern: many landlocked countries restrict trade in the very services that connect them with the rest of the world. On average, telecommunications and air-transport policies are significantly more restrictive in landlocked countries than elsewhere. The phenomenon is most starkly visible in Sub-Saharan Africa and is associated with lower levels of political accountability. This paper finds evidence that these policies lead to more concentrated market structures and more limited access to services than these countries would otherwise have, even after taking into account the influence of geography and incomes, and the possibility that policy is endogenous. Even moderate liberalization in these sectors could lead to an increase of cellular subscriptions by 7 percentage points and a 20-percent increase in the number of flights. Policies in other countries, industrial and developing alike, also limit competition in international transport services. Hence,"trade-facilitating"investments under various"aid-for-trade"initiatives are likely to earn a low return unless they are accompanied by meaningful reform in these services sectors.Transport Economics Policy&Planning,Markets and Market Access,Public Sector Corruption&Anticorruption Measures,Economic Theory&Research,ICT Policy and Strategies
Consequences of Vertical Separation and Monopoly: Evidence from the Telecom Privatizations
Two common policy instruments used by governments around the world to increase the availability of basic telephony (i.e., local, long distance, and international service) have been: (1) award monopoly rights on basic services to cross-subsidize residential local telephony; and (2) separate vertically (i.e., structural separation) the owner of the local fixed network from the provider of long distance or international telephone services. I use data from a panel of 67 countries during the seven years following the privatization of the telephone monopoly and find that contrary to wide spread beliefs: (1) monopoly on basic services is not associated with lower residential telephony prices; quite the opposite, monopoly increases residential local prices; (2) monopoly does not help universal service provision and lowers the use of international telephony; and (3) mandatory vertical separation reduces international telephony usage and the number of fixed lines in service. In summary, monopoly and vertical separation harm those consumers that were precisely designed to help: the downstream (business) users of international telephony and the upstream users of residential local telephony.
Services reform and manufacturing performance : evidence from India
The growth of India's manufacturing sector since 1991 has been attributed mostly to trade liberalization and more permissive industrial licensing. This paper demonstrates the significant impact of a neglected factor: India's policy reforms in services. The authors examine the link between those reforms and the productivity of manufacturing firms using panel data for about 4,000 Indian firms from1993 to 2005. They find that banking, telecommunications, insurance and transport reforms all had significant, positive effects on the productivity of manufacturing firms. Services reforms benefited both foreign and locally-owned manufacturing firms, but the effects on foreign firms tended to be stronger. A one-standard-deviation increase in the aggregate index of services liberalization resulted in a productivity increase of 11.7 percent for domestic firms and 13.2 percent for foreign enterprises.Transport Economics Policy&Planning,Banks&Banking Reform,Emerging Markets,E-Business,Economic Theory&Research
Going Beyond Counting First Authors in Author Co-citation Analysis
The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
An Assessment of Telecommunications Reform in Developing Countries’, World Bank Policy Research Working Paper 2909
Fink, Mattoo, and Rathindran analyze the effect of The authors find that both privatization and policy reform in basic telecommunications on sectoral competition lead to significant improvements in performance using a new panel data set for 86 performance. But a comprehensive reform program, developing countries across Africa, Asia, the Middle East, involving both policies and the support of an and Latin America and the Caribbean over the period independent regulator, produced the largest gains-an 1985 to 1999. The authors address three questions: 8 percent higher level of mainlines and a 21 percent o What impact do specific policy changes-relating to higher level of productivity compared to years of partial ownership and competition-have on sectoral and no reform.

Appropriate Similarity Measures for Author Cocitation Analysis
We provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
