Foreign currency borrowing by small firms in emerging markets: When domestic banks intermediate dollars
No full textThis paper investigates what induces small firms in an emerging market economy to borrow dollar credit from domestic banks. Our data are from a unique survey of firms in Lebanon. The findings complement studies of large firms with foreign currency loans from foreign lenders. Exporters, naturally hedged against currency risk, are more likely to incur dollar debt. Firms also partly hedge themselves by passing currency risk to customers and suppliers. Less opaque firms with easily verifiable collateral and higher net worth are more likely to access dollar credit. Firms reliant on formal financing (banks and supplier credit) are more likely to contract dollar debt than firms reliant on informal financing (family, friends and moneylenders). Bank relationships, however, do not increase the dollar debt likelihood. And finally, profitable firms are less likely to have dollar debt. Information frictions and limited collateral, therefore, constrain dollar credit even when it is intermediated domestically. © 2012 Elsevier B.V.Aghion P, 2000, EUR ECON REV, V44, P728, DOI 10.1016-S0014-2921(99)00053-7; Aguiar M, 2005, J DEV ECON, V78, P95, DOI 10.1016-j.jdeveco.2004.06.012; Allayannis G, 2003, J FINANC, V58, P2667, DOI 10.1046-j.1540-6261.2003.00619.x; Ayyagari M, 2011, J FINANC QUANT ANAL, V46, P1545, DOI 10.1017-S0022109011000378; Bernanke B.S., 2010, COMMUNICATION 0712; Bleakley H, 2008, REV ECON STAT, V90, P612, DOI 10.1162-rest.90.4.612; Bordo MD, 2010, J INT MONEY FINANC, V29, P642, DOI 10.1016-j.jimonfin.2010.01.002; Broda C, 2006, J MONEY CREDIT BANK, V38, P963, DOI 10.1353-mcb.2006.0050; Brown M, 2011, J FINANC INTERMED, V20, P285, DOI 10.1016-j.jfi.2010.12.001; Burnside C, 2001, EUR ECON REV, V45, P1151, DOI 10.1016-S0014-2921(01)00090-3; Caballero RJ, 2003, J FINANC, V58, P867, DOI 10.1111-1540-6261.00549; Caballero RJ, 2002, AM ECON REV, V92, P33, DOI 10.1257-000282802320188952; Calvo G., 1990, CAPITAL MARKETS DEBT; Calvo GA, 2002, ECON TRANSIT, V10, P393, DOI 10.1111-1468-0351.00117; De Nicolo G, 2005, J BANK FINANC, V29, P1697, DOI 10.1016-j.jbankfin.2004.06.033; Eichengreen B, 2005, OTHER PEOPLES MONEY; Gelos RG, 2003, ECON LETT, V78, P323; Grais Wafik, 2003, 3050 WORLD BANK; Hamdan K., 2004, 0417 EC RES FOR; Hausmann R., 2011, J GLOBALIZATION DEV, V2, P1; Hubbard RG, 1998, J ECON LIT, V36, P193; Jeanne O, 2000, EUR ECON REV, V44, P719, DOI 10.1016-S0014-2921(99)00052-5; Kiyotaki N, 1997, J POLIT ECON, V105, P211, DOI 10.1086-262072; Luca A, 2008, J BANK FINANC, V32, P858, DOI 10.1016-j.jbankfin.2007.06.003; Martinez L, 2002, J DEV ECON, V69, P315, DOI 10.1016-S0304-3878(02)00091-3; Rappoport V, 2009, J MONETARY ECON, V56, P979, DOI 10.1016-j.jmoneco.2009.09.002; Schimmelpfennig Axel, 2008, 0817 IMF; Schneider M, 2004, REV ECON STUD, V71, P883, DOI 10.1111-j.1467-937X.2004.00308.x; Tornell A, 2002, IMF STAFF PAPERS, V49, P1110
The demand elasticity of mobile telephones in the Middle East and North Africa
No full textThis study investigates the components of the mobile telephone demand in several countries in the Middle East and North Africa (MENA) between 1995 and 2007. We find that the magnitude of demand elasticities do not entice collusive behavior between service providers because the effect of price reductions is neutral on total revenues. We also find that the cost of service and administrative corruption have a strong negative effect on mobile penetration, which, surprisingly, is higher in countries with more unequal income distribution. The study discusses how market reforms in developed countries fail to translate to developing countries because several negative externalities are often overlooked. © 2014 Published by Elsevier B.V
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 shocks and international cost of equity destabilization. Evidence from the MENA region
No full textThis paper investigates whether foreign financial shocks can destabilize the cost of equity in emerging markets. After a theoretical discussion, we develop annual metrics for the international cost of equity, financial integration, spillovers and shift-contagion vulnerability in a sample of 535 Middle East and North African firms from Egypt, Tunisia, Morocco and Jordan over the 1998-2011 period. We then analyze the impact of foreign shocks on the international cost of equity, using a set of SGMM and PVAR models. Our results indicate that external shocks can increase the cost of equity in mature emerging markets. © 2014.Adelman I., 2000, Structural Change and Economic Dynamics, V11, DOI 10.1016-S0954-349X(99)00019-3; ARELLANO M, 1995, J ECONOMETRICS, V68, P29, DOI 10.1016-0304-4076(94)01642-D; Barclay R, 2010, EMERG MARK REV, V11, P49, DOI 10.1016-j.ememar.2009.11.002; Baur Dirk G, 2009, Journal of Asian Economics, V20, DOI 10.1016-j.asieco.2009.04.008; Beirne J., 2008, 08286 IMF; BIKHCHANDANI S, 1992, J POLIT ECON, V100, P992, DOI 10.1086-261849; Blundell R, 1998, J ECONOMETRICS, V87, P115, DOI 10.1016-S0304-4076(98)00009-8; Calvo GA, 2000, AM ECON REV, V90, P59, DOI 10.1257-aer.90.2.59; Calvo GA, 2000, J INT ECON, V51, P79, DOI 10.1016-S0022-1996(99)00038-0; Collins D., 2006, EMERG MARK REV, V7, P67, DOI 10.1016-j.ememar.2005.06.003; Damodaran A., 2012, EQUITY RISK PREMIUM; Edison NJ., 2003, IMF WORKING PAPERS; ERRUNZA V, 1985, J FINANC, V40, P105, DOI 10.2307-2328050; Forbes K., 2000, NBER WORKING PAPERS; Frank N., 2008, 08200 IMF; Harris RDF, 1999, J ECONOMETRICS, V91, P201, DOI 10.1016-S0304-4076(98)00076-1; Henry PB, 2000, J FINANC, V55, P529, DOI 10.1111-0022-1082.00219; Hirshleifer D, 2006, J FINANC ECON, V81, P311, DOI 10.1016-j.jfineco.2005.05.006; Kaminsky G., 2003, NBER WORKING PAPERS; Khallouli Wajih, 2012, Journal of Economic Integration, V27, P134; Kodres LE, 2002, J FINANC, V57, P769, DOI 10.1111-1540-6261.00441; Lagoarde-Segot T., 2013, RES INT BUS FINAN, V27, P183; Lagoarde-Segot T., 2010, WORLD ECON, V32, P1478; Lagoarde-Segot Thomas, 2008, J INT FINANC MARK I, V18, P94, DOI 10.1016-j.intfin.2006.06.003; Meza F, 2011, J INT ECON, V85, P317, DOI 10.1016-j.jinteco.2011.06.001; Neumann RM, 2009, INT REV ECON FINANC, V18, P488, DOI 10.1016-j.iref.2008.04.005; Patro DK, 2005, J BANK FINANC, V29, P1671, DOI 10.1016-j.jbankfin.2004.06.032; Roodman D, 2009, OXFORD B ECON STAT, V71, P135, DOI 10.1111-j.1468-0084.2008.00542.x; Sims CA, 1999, ECONOMETRICA, V67, P1113, DOI 10.1111-1468-0262.00071; Stulz R.

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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
