Absolute and Conditional Convergence: Its Speed for Selected Countries for 1961--2001
No full textThe study gives the theoretical justification for the per capita growth equations using Solovian model(1956) and its factor accumulation assumptions. The different forms of the per capita growth equation is used to test for 'absolute convergence' and 'conditional convergence' hypotheses and also work out the speed of absolute and conditional convergence for selected countries from 1961-2001.We use cross sectional data of GDP per capita levels and growth rates of European countries EU16(EU15 +United Kingdom), South Asian Countries (5), some East Asian (8) and CIS Countries (15) to test for 'absolute convergence' hypothesis for four different periods 1961-2001,1970-2001,1980-2001,1990-2001.Only EU and East Asian countries together have shown uniform evidence of absolute convergence in all periods. While EU as a region has shown significant evidence of absolute convergence in two periods, 1961-2001 and 1970-2001, there is no convincing statistical evidence in favor of absolute convergence in the last two periods: 1980-2001 and 1990- 2001.This latter evidence with declining rate of economic growth for EU since 1961 points to a challenge for designing EUs regional policies which also have to cope up with many East European and Baltic nations who joined EU recently. The speed of absolute convergence in the four periods range between 0.99-2.56 % p.a. (2% for the EU was worked out by Barro and Xavier Sala-i-Martin, 1995, for European regions) for EU while it ranges between 0.57-1.16 % p.a. for the countries in East Asia and EU regions together. However, there is no evidence of convergence among the South Asian countries in all periods and some major CIS republics since 1966.There is however tendency for absolute convergence among countries of South Asia, East Asia and European Union together particularly after the 1980s. Conditional convergence is prevalent among almost all pairs of regions in our sample except East Asian and South Asian nations together.Speed of conditional convergence ranges from 0.2 % in an year to 22%.In the European nations, the speed of conditional convergence works out be nearly 20 % unlike the speed of absolute convergence which hovered around 2 %.Such results would mean that countries in Europe are converging very quickly to their own potential level of incomes per capita but not so quickly to a common potential level of income per capita.The elasticity of output which is also estimated ranges from 0.54 to 0.91 implying that capital is to be interpreted as broad capital inclusive of human capital stock.It seems that human capital not only affects technological progress but affects output levels directly by increasing capital stock levels implying that the assumption of including human capital stock in the production function were appropriate in Mankiw,Romer and Weil(1992). The results for the speed of conditional convergence favors use of an extended Solovian model inclusive of human capital.Conditional beta convergence seems to be a better empirical exercise(as evident from our theoretical model and empirical results ) because it reflects the convergence of countries after we control for differences in steady states .Conditional convergence is simply a confirmation of a result predicted by the neoclassical growth model:that countries with similar steady states exhibit convergence.It does not mean that all countries in the world are converging to the same steady state,only that they are converging to their own steady statesGrowth equation, absolute convergence, conditional convergence, speed of absolute and conditional convergence, elasticity of output with respect to capital, half life of convergence
Growth Accounting for Some Selected Developing, Newly Industrialized and Developed Nations from 1966-2000: A Data Envelopment Analysis
Full text linkWe work out technical efficiency levels of 29 countries consisting of some selected South Asian, East Asian and EU countries using data envelopment analysis. Luxembourg has an efficiency score of one(most efficient) in all the years .Netherlands also has an efficiency score of one in 1966,1971,1976 and 1981.Japan,UK,Belgium,Ireland,Indonesia,Spain and Germany has an efficiency score of one in at least one of the years from 1966 to 2000.In the year 2000 though mean efficiency levels(without including life expectancy as input) of South Asian countries is higher than the European Union Countries and East Asian countries. Japan has the highest average efficiency followed by Hong Kong in the East Asian region in the period 1966-2000. We also decompose labor productivity growth into components attributable to technological changes (shifts in the overall production frontier), technological catch up or efficiency changes(movement towards or away from the frontier),capital accumulation(movement along the frontier) and human capital accumulation( proxied by life expectancy).The overall production frontier is constructed using deterministic methods requiring no specification of functional form for the technology nor any assumption about market structure or the absence of market imperfections. Growth accounting results tend to convey that for the East Asian and the South Asian countries efficiency changes(technological catch up) have contributed the most, while for the European countries it is the technical changes which has contributed more to labour productivity changes between 1966-2000. We also analyze the evolution of cross country distribution for the 29 countries included in our sample using Kernel densities. It seems that there are other factors like trade openness,quality of governments,population rate of growth, savings rate, corruption perception indices, rule of law index, social capital and trust variables, formal and informal rules governing the society, among others, rather than the ones that are included below for the growth accounting exercise which may be responsible for productivity accounting on point to point basis. For all the seven periods(point to point basis) we see a major role played by technological changes and efficiency changes together to account for the current period counterfactual distributions and for the bimodal distribution in year 2000, and for the period 1966-2000(not point to point basis –an excercise done similar to Kumar and Russell(2002)) we find technical changes and its combination with other tripartite and quadripartite changes jointly account for the bimodal distribution in year 2000.However, from this growth accounting exercise, we do find that there is convergence in statistical terms of efficiency changes and human capital accumulation across countries of the EU, South Asian and East Asian regions.: Data envelopment analysis, growth accounting, technical efficiency, efficiency change, technological change, capital accumulation, human capital accumulation, kernel smoothing, cross country labor productivity distribution and counterfactual distributions

Industrial Sector Growth Accounting of Some Indian States and Union Territories: A Data Envelopment Analysis
No full textWe work out technical efficiency levels of the Indian States and Union Territories using Data Envelopment Analysis from 1980-81 to 1997-98. We decompose net value added per worker growth into components attributable to technological changes (shifts in the overall production frontier),technological catch up(movement towards or away from the frontier) and capital accumulation(movement along the frontier).The overall production frontier is constructed using data envelopment analysis, requiring no specification of functional form for the technology nor any assumption about market structure or the absence of market imperfections. We analyze the evolution of cross states net value added distribution for the 22 Indian states and union territories from 1980-81 to 1997-98 using Kernel densities. The efficiency factor accounted for 5.07 % only,technological change accounted for 11.66 % while the contribution of capital deepening is relatively higher at 17.82% while the point to point productivity change is of 11.66%. The overall averages provide evidence of productivity improvements of 173.29 over 1980-81(base) to 1997-98(current year) period.The efficiency factor accounted for -10.63% % only,technological change accounted for 173.20 while the contribution of capital deepening is 42.52% TO ACCOUNT for 173.20% overall PRODUCTIVITY CHANGE(not point to point). The results seems to suggest that there are other factors suggested in the literature like barriers to exit, a maze of rules and regulations, government import policies, high concentration, among others, rather than the ones that are included below for the growth accounting exercise which can totally account for point to point and overall productivity changes from 1980-81 to 1997-98..Also, we do find that the efficiency levels for the Indian states have gone down from what it was in 1980s to what it were in 1997-98.However,the smaller states have out performed the larger states in terms of their efficiency levels. Also, States which had relatively lower efficiency levels and net value added per worker in 1980-81 are the ones which have grown faster than other states. We see tendency of catching up among the Indian states in terms of net value added per worker..growth accounting, data envelopment analysis, technical efficiency, efficiency change, technological change, capital deepening,, kernel smoothing, cross country labor productivity distribution
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
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
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
