The Impact on Structural Reforms on Employment Growth and Labour Productivity: Evidence from Bulgaria and Romania
Get PDFUsing firm-level data from Bulgaria and Romania, this paper addresses a lacuna in the transition literature, namely, the link of firm-level employment turnover with firm-level growth in labour productivity. The results suggest that while net job creation at the firm level was affected by privatization in Bulgaria, privatization in Romania did not have any effect on firm-level employment growth. Further, Olley-Pakes (1996) decomposition indicates that in Bulgaria, over time, resources moved from less productive firms to more productive firms in almost all industries, but that in Romania such a phenomenon was observed in less than half of the industries. At the same time, the Grilliches-Regev (1995) decomposition indicates that in both these countries mobility of labour across firms, i.e., the process of job creation and job destruction at the firm level, contributed more to productivity changes than did other firm-level characteristics and industry-level factors affecting productivity. Finally, we find that the rate of employment changes in Bulgarian firms has a significant impact on the country’s firm-level productivity changes. Regressions using Romania data, however, do not provide any support for this observation.job flows, employment growth, labour productivity, Bulgaria, Romania

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Is household income diversification a means of survival or a means of accumulation? Panel data evidence from Tanzania
No full textWhat drives income diversification among rural households in developing countries? A large literature has examined whether household income diversification is a means of survival or a means of accumulation, which has so far remained inconclusive. This paper attempts to evaluate which explanation of household income diversification – diversification as survival or diversification as accumulation – stands up to empirical scrutiny. We use household panel data from Tanzania of approximately 800 households for four years and use fixed and random effects models to sweep out unobserved households’ attitudes to risk that may be correlated with household income diversification behaviour. We also use instrumental variable methods to address the possibility of reverse causality and that the household’s income status may be endogenous to its diversification behaviour. Our results suggest that the ‘diversification as accumulation’ motive of household income diversification seems to have stronger empirical validity in the Tanzanian context.
Monopolistic wages or efficient contracts?
No full textUsing a representative sample of medium and large firms, this paper explores the process of employment and wage bill determination in the Bulgarian manufacturing sector. The results suggest that, during 1997-2001, the labour market behaviour of these firms was consistent with weakly efficient contracting and employment elasticity with respect to both sales and wages similar to that of the fastest-reforming Central and Eastern Europe economies. Although a case study using data on sell-off deals by the Privatization Agency suggests that the largest firms selected for cash privatization may have exhibited higher preference for wage enhancement than employment protection, the results do not bring into question the efficient performance of the post-crisis labour market in Bulgaria. Importantly, the study rejects the hypothesis that either persistent government stakes or mass privatization may have led to efficiency deterioration.
