Energy market projections and differentiated carbon abatement in the European Union
Full text linkWe analyze the economic effects of the differentiated targets for carbon abatement in six European Union member states. Our recursively-dynamic model includes a detailed representation of trade and energy consumption and incorporates optimistic projections for future energy markets provided by the European Commission as the Business-as-Usual scenario. In the base case we find that the EU implementation of the Kyoto Protocol implies low overall costs and a relatively even cost distribution across member states. We also show that a less optimistic development in energy efficiency implies higher costs in all countries, especially in those with high abatement costs. Finally, we find that uniform abatement targets increase overall costs marginally but changes the cost distribution significantly, holding total EU emissions constant. --
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Foreign direct investment in services and the domestic market for expertise
Full text linkA growing body of evidence suggests that the close availability of diverse business services is important for economic growth. Producer services such as managerial and engineering consulting can provide specialized knowledge to help domestic firms develop at lower unit cost. But these intermediate services are often nontraded, or costly to trade, which may be one reason that cities and industrial complexes form and economic performance differs across regions. Because services are costly to trade, foreign services are best transferred through foreign direct investment. This has important implications for public policy. Policies that affect foreign direct investment differ considerably from those that affect trade in goods. The authors develop a model of services, results from which show that: A) Liberalizing restraints on inward foreign direct investment has a powerful positive impact on the income and welfare of the importing country. The impact is much stronger than in traditional competitive models of trade in goods. B) Policies to protect domestic skilled labor against competition from imported services can have the perverse effect of lowering returns to domestic skilled labor-because while imported services economize on the use of domestic skilled labor (compared with domestic service industries), the positive effects on scale and productivity in the downstream industry can be powerful enough that the real wages of domestic skilled labor rise after the liberalization of foreign direct investment in service industries. In other words, domestic skilled labor and foreign direct investment are partial-equilibrium substitutes in the model but are typically general-equilibrium complements. C)The increase in the variety of imported services leads to increased total factor productivity in downstream industries, but the relative impact on downstream industries depends on how intensively they use intermediate services. The differential in effects on productivity in the production of final goods can be strong enough that permitting foreign direct investment can actually affect whether a good is exported rather than being imported. Policymakers should be aware that protection of a domestic service industry affects different constituencies differently. Although domestic capital owners may be adversely affected by foreign direct investment, domestic skilled workers in the industry are likely to see demand for their skills-and their real wages-rise. Moreover, downstream industries that use the service unambiguously benefit from foreign direct investment and their expansion can be surprisingly strong.Payment Systems&Infrastructure,Environmental Economics&Policies,Economic Theory&Research,Banks&Banking Reform,Health Economics&Finance,Environmental Economics&Policies,Economic Theory&Research,Health Economics&Finance,Banks&Banking Reform,Municipal Financial Management
Variations on the Author
Full text link“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
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe 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
Chile's regional arrangements and the Free Trade Agreement of the Americas : the importance of market access
Full text linkUsing a multisector, computable general equilibrium model, the authors examine Chile's strategy of negotiating bilateral free trade agreements with all of its significant trading partners (referring to this policy as additive regionalism). They also evaluate the Free Trade Agreement of the Americas (FTAA) and global free trade. Among Chile's bilateral regional agreements, only Chile's agreements with"Northern"partners provide enough market access to offset the costs to Chile of trade diversion. Because of preferential market access, however, additive regionalism is likely to provide Chile with many times as many gains as the static welfare gains from unilateral free trade. The authors find that at least one partner country loses from each of the regional trade agreements they consider, and excluded countries as a group they always lose. They estimate that the FTAA produces large welfare gains for the members, with the European Union being the big loser. Gains to the world from global free trade are estimated to be at least 36 times greater than gains from the FTAA. Even countries of the Americas in aggregate gain more from global free trade than from the FTAA.Rules of Origin,Economic Theory&Research,Environmental Economics&Policies,Trade Policy,Payment Systems&Infrastructure,TF054105-DONOR FUNDED OPERATION ADMINISTRATION FEE INCOME AND EXPENSE ACCOUNT,Trade and Regional Integration,Economic Theory&Research,Environmental Economics&Policies,Rules of Origin
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
Trade liberalization and endogenous growth in a small open economy : a quantitative assessment
Full text linkThe authors develop a numerical endogenous growth model approximating an infinite horizon, which allows them to investigate the relationship between trade liberalization and economic growth. Economic theory generally implies that trade liberalization will improve economic growth, and the two phenomena are positively correlated in empirical tests, but the connection is not well-substantiated in numerical general equilibrium models. In the authors'model, an intermediate input affects aggregate output through a Dixit-Stiglitz function. Additional varieties provide the engine of growth in this framework and the existence of this mechanism magnifies the welfare costs. In this model with lump sum revenue replacement, reducing a tariff from 20 percent to 10 percent produces a welfare increase (in terms of Hicksian equivalent variation over the infinite horizon) of 10.7 percent of the present value of consumption in their central model, where the economy is assumed to be unable to borrow on international financial markets. If macroeconomic and financial reforms are in place that would allow international borrowing, however, the same tariff cut is estimated to result in a 37 percent increase in Hicksian equivalent variation. On the other hand, if inefficient replacement taxes must be used in an economy without the capacity to borrow internationally, the gains would be reduced to 4.7 percent. Larger tariff cuts--typical of those in many developing countries over the past 30 years--produce larger estimated welfare gains at least proportionate to the size of the cut. The authors apply the model to five developing countries and estimate the impact of the tariff changes those countries plan to undertake as part of Uruguay Round commitments. Because of the dynamic effects, estimated gains are considerably larger than those found in the literature on the impact of the Uruguay Round.International Terrorism&Counterterrorism,Economic Theory&Research,Environmental Economics&Policies,Banks&Banking Reform,Labor Policies,Inequality,Economic Theory&Research,Environmental Economics&Policies,TF054105-DONOR FUNDED OPERATION ADMINISTRATION FEE INCOME AND EXPENSE ACCOUNT,Trade and Regional Integration
