Three cheers for industry: Is manufacturing linked to R&D, exports, and productivity growth?
No full textMany industrialized countries in Europe and North America have experienced a steady decline in the manufacturing sector over the last few decades. Amid growing concerns that outsourcing and offshoring have destabilized European economies, policymakers have suggested that a large manufacturing sector can: i) boost R&D, ii) encourage exporting, and iii) raise productivity. We examine these claims. Non-parametric plots and regressions show a robust positive association between the manufacturing sector and Business Expenditures on R&D (BERD), while the relationship between manufacturing and exports or productivity is more elusive. Our results suggest that increasing the manufacturing value added share may lead to an overall higher R&D intensity, because the manufacturing sector generally has a higher R&D intensity than the non-manufacturing business sector, although manufacturing sector R&D does not seem to create externalities leading to higher non-manufacturing R&D
Does exporting cause productivity growth? Evidence from Chilean firms
No full textDoes exporting increase firm productivity, or are increased export sales caused by the firm's ability to increase its productivity? This paper provides new empirical evidence on the causal relation between trade and productivity, adopting a structural vector autoregressive analysis combined with identification algorithms from the machine learning literature. We focus on a well-studied country (Chile) and on already-exporting firms (intensive margin). We identify the contemporaneous and lagged causal structure between firm productivity and export growth using two different machine learning algorithms based on independent components analysis (ICA), which exploit the non-Gaussian distribution of the data to recover the independent structural shocks that drive the observed variables. Our findings show that, for Chilean firms, productivity growth causes export growth in the same year, but that the reverse does not apply. Export growth also has no causal effect on TFP growth in subsequent years. To increase sales in the foreign market, firms should first also increase productivity. The increased presence in the foreign market does not contribute to such productivity growth
Firm growth and barriers to growth among small firms in India
No full textEmpirical work on micro and small firms focuses on developed countries, while existing work on developing countries is all too often based on small samples taken from ad hoc questionnaires. The census data we analyze here are fairly representative of small business structure in India. Consistent with findings from prior research on developed countries, size and age have a negative impact on firm growth in the majority of specifications. Enterprises managed by women have lower expected growth rates. Proprietary firms face lower growth on the whole, especially if they are young firms. Exporting has a positive effect on firm growth, especially for young firms and for female-owned firms. Although some small firms are able to convert know-how into commercial success, we find that many others are unable to translate it into superior growth
Growth processes of Italian manufacturing firms
Full text linkThis paper presents a multidimensional empirical analysis of firm growth. Exploiting census data on Italian manufacturing firms, 1989-1997, we estimate a reduced-form VAR to analyze the co-evolution of employment growth, sales growth, growth of profits and labour productivity growth. Our main findings suggest that (i) employment growth precedes sales growth; (ii) productivity growth lacks any strong association with subsequent growth of the other indicators; (iii) profits growth represents the 'absorbing dimension' of the growth processes. This picture contrasts with 'accelerator models', predicting sales are the driver of the growth process, and is also at odds with theories of firm-industry evolution assuming productivity or profits advantages to be the driver of strong market selection/reallocation mechanisms. Instead, the findings reveal the existence of (weak) Penrose and (strong) Kaldor-Verdoorn effects, and more generally convey the view that employment growth is the key driver of firm expansion, while profits, once made, are not reinvested
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
Barriers to innovation and firm productivity
No full textThe paper analyzes the effect of financial, knowledge, demand, market structure and regulation barriers to innovation on firms’ economic performance. It contributes to the literature on barriers to innovation by accounting for the heterogeneous effects that each barrier has on firms across the productivity distribution. We do so by employing both quantile regression techniques and matching estimators on this UK CIS panel 2002–2010 merged with the Business Structure Database. While we find evidence that both the cost and also the availability of finance negatively affect productivity across the whole distribution, the lack of qualified personnel mostly hinders high productivity firms. Moreover, quantile regression reveals some interesting variation in effect sizes across the (conditional) productivity distribution.</p
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
