Inter-industry Wage Differences and Individual Heterogeneity
No full textTwo well-established findings are apparent in the analyses of individual wage determination: cross-section wage equations can account for less than half of the variance in earnings and there are large and persistent inter-industry wage differentials. We explore these two empirical regularities using longitudinal data from the British Household Panel Survey (BHPS). We show that around 90% of the variation in earnings can be explained by observed and unobserved individual characteristics. However, small – but statistically significant – industry wage premia do remain, and there is also a role for a rich set of job and workplace controls
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
Unemployment equilibria and input prices: theory and evidence from the United States
Get PDFThis paper develops an efficiency-wage model where input prices affect the equilibrium rate of unemployment. We show that a simple framework based on only two prices (the real price of oil and the real rate of interest) is able to explain the main post-war movements in the rate of U.S. joblessness. The equations do well in forecasting unemployment many years out-of-sample, and provide evidence that the oil-price spike associated with Iraq’s invasion of Kuwait appears to be a component of the “mystery” recession which followed
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
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
Empirical Studies of Equilibrium-Correction Dynamics and Financial market Linkages in the Macroeconomy.
No full textWe apply a general-to-specific modelling approach to estimate a six-dimensional parsimonious structural vector error-correction model of the US economy. We use graph theory methods to determine the instantaneous causal structure of the system from the data thus, overcoming the common problem of making ad-hoc assumptions about the order of causality. Model reduction procedures allow us to control for the curse-of-dimensionality inhibiting such high-dimensional vector autoregressive systems. The corporate-government bond yield risk premium is identified as one of five cointegration relations characterising the economy. Monetary policy reacts to the risk premium and
the term structure of interest rates long-run relationships. Monetary policy is also neutral in the long-run, with a contractionary shock to the federal funds rate leading to only a temporary increase in bond yields and fall in inflation and capacity utilisation. In addition, corporate bonds react faster and by more than do Treasuries, making the corporate-government bond yield spread a potential target in implementing monetary policy.
Joint modelling of fiscal and monetary policies should elucidate on their interaction. We construct an eight-dimensional parsimonious structural vector equilibrium correction model of the US macroeconomy over the last five decades. The fiscal deficit is found to be one of five cointegration vectors, constraining fiscal policy in the long-run. In contrast, the share of the government sector is found not to be mean reverting. Impulse-response analysis of the parsimonious system facilitates precise measurement of the dynamic Keynesian fiscal multiplier, where we distinguish between deficit-spending and balanced-budget spending shocks (as in the so-called Haavelmo, 1945, theorem). Our estimates of the long-run multiplier are 1.62 for a bond-financed spending shock and 1.77 for a tax-financed spending shock, with both being greater than 1 and significant at a 95% confidence level. Monetary policy is neutral in the long-run except for the level of output on which a permanent effect is observed. Increasing the federal funds rate by a percentage point is followed by falling tax revenues while government spending is largely unchanged, thus inflating the fiscal deficit in the short-run and medium-run.
One aspect of increasing inter-dependence between economies can be seen in the internationalisation of financial markets. We investigate the propagation of domestic and foreign shocks through US and UK financial markets for money, bonds, equities, and the exchange rate. We focus on within-market, cross-market, and cross-border linkages. This study is especially relevant for small, open economies which are most exposed to foreign-originated shocks. US markets dominate cross-border spillover effects and explain about 7.5% of the variation in UK asset markets. This is in contrast to the 0.15% of the variation in US financial markets that is explained by shocks from UK markets. The strongest effects are in equity and money markets. Own idiosyncratic shocks have the
highest explanatory power and account for 54%-94% of the variation in returns
