Drivers of firm growth: Micro-evidence from Indian manufacturing
Full text linkThe paper presents micro evidence on firm dynamics for enterprises in Indian Manufacturing sectors on the grounds of Prowess database provided by the Centre for Monitoring Indian Economy (CMIE) covering the period 1991-2010. The parameterization of the distributions of growth exhibit high level heterogeneity displayed among firms even within the same sector, which widens over time. The transition probabilities matrix reveals the coexistence of firms with very different characteristics and performance within sectors. Given the wide heterogeneities, the paper resorts to quantile regression to identify the differential effect of regressors at different deciles of the conditional distrubution
Pension funds and Stock Market Volatility: An Empirical Analysis of OECD countries
No full textThe paper explores the empirical relationship between the share of pension funds assets invested in stocks and stock market volatility in OECD markets. For this purpose, by using panel data of 34 OECD countries from 2000 to 2010, we estimate both a random-effects panel model and a Prais–Winsten regression with panel-corrected standard errors and autoregressive errors. The estimations document that there is a significant negative relationship between the share of pension funds assets invested in stocks and stock market volatility in OECD markets. The binary probit and logit models further validate the argument that pension funds as institutional investors can dampen stock market volatility
What a firm produces matters: Processes of diversification, coherence and performances of Indian manufacturing firms
No full textEconomic growth and development of a country involves the accumulation of knowledge and dynamic capabilities. Past research has begun to investigate capability accumulation and macro-economic development of countries and sectors, and the role of new products in these processes. In this work, we focus on the firm-level process of capability accumulation and diversification in a developing country, namely, India. First, we explore the drivers of firm diversification strategies, and the effects of diversification upon firm performance in terms of profitability and sales growth. Second, we look at the idiosyncratic characteristics of different products, trying to identify the synergies of a product line with respect to the overall product basket of the firm – i.e. the “coherence” of its diversification patterns. We observe that the future performance of firms crucially depends on the interactions between the products they produce.</p
The role of domestic-firm knowledge in international patent collaborations: evidence from Indian firms
No full textIn this paper, we analyse the role of international patent collaborations in the performance of domestic firms and how the relationship is augmented by the pre-existing capabilities of the domestic firms. Using data on Indian firms, we study patterns of co-invention by Indian firms and foreign partners. The results confirm the crucial role played by the absorptive capacity of domestic firms in enhancing benefits from patent collaborations. Strikingly, we find that the coefficient associated to foreign collaboration has a positive effect on performance only when complemented with previous innovative capabilities. The evidence we present in this work contributes to existing knowledge on the microeconomics behind the process of technological capability accumulation and catching up in developing countries
The cost-quantity relations and the diverse patterns of 'learning by doing': Evidence from India
Full text linkLearning-by-doing is usually identified as a process whereby performance increases with experience in production. Of course such form of learning is complementary to other patterns of capability accumulation. Still, it is fundamental to assess its importance in the process of development. The paper investigates different patterns of learning by doing studying learning curves at product level in a catching-up country, India. Cost-quantity relationships differ a lot across products belonging to sectors with different technological intensities. We find also, puzzlingly, in quite a few cases, that the relation price/cumulative quantities is increasing. We conjecture that this is in fact due to quality improvement and vertical product differentiation. Circumstantial evidence rests on the ways differential learning patterns are affected by firm spending on research and capital investments. Finally, our evidence suggests that learning or performance improvement over time is not just a by-product of the mere repetition of the same production activities, as sometimes reported in previous studies, but rather it seems to be shaped by deliberate firm learning efforts
Making one’s own way: jumping ahead in the capability space and exporting among Indian firms
No full textThis paper provides large scale evidence on the determinants of international competitiveness of Indian manufacturing firms, focusing in particular on the role of technology, costs and imported intermediate inputs. Our evidence suggests that innovation, in particular R&D investment, is positively related to both firms’ probability to export and firms’ export volumes. We also find that imported intermediate inputs, incorporating foreign technology is strongly associated with expanding export activities of firms. Finally, and in contrast to much of previous evidence on developed economies, we find that higher productivity or lower unit labour costs are not systematically associated with the probability to enter export markets, but they are positively related to higher export volumes. Overall our results point to the existence of a pattern of involvement in international trade for firms in developing countries that is not relying as a main driver on cost competitiveness
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
