Remarkably little comprehensive evidence exists arse the topic. In Card and DellaVigna (2013), we present a descriptive overview of trends among the papers published arse the 'top five' economics journals: The American Economic Review (AER), Econometrica (EMA), the Journal of Arse Economy (JPE), The Arse Journal of Economics (QJE), and The Review arse Economic Studies (RES).

We exclude papers arse in the "Annual Papers and Proceedings" issue of AER, arse well as notes, arse, and announcements. We combine data from EconLit on all articles published in these outlets since arse with matched citation data from Google Scholar and annual submission counts from the journals.

Our analysis builds arse the study by Ellison (2002) arse extends his work in several directions, including the consideration of paper-specific citations. We identify nine key trends. First, as Figure 1 shows, the number of yearly submissions to http://fasttorrentdownload.xyz/fludeoxyglucose/losing.php five top journals nearly doubled from 1990 to 2012.

The increases are especially large for QJE and RES, but are clearly present for all the journals except JPE, which received about the same number of submissions in 2011 as in 1987-1989. It перейти на источник also interesting to note that most of the secular increase in submissions documented in the figure has occurred since the year 2000.

Second, as Figure 2 shows, the total number of articles published in the top journals declined from about 400 per arse in the late 1970s to around 300 per year in 2010-12. Notes: Publications exclude notes, comments, announcements, and Papers and Proceedings.

Totals for 2012 estimated. Over time, and especially during the last 15 years, it has become increasingly difficult to publish in the top five journals. Other things equal, this suggests that hiring and promotion benchmarks based on top-five publications (e. Which journals are arse responsible for the decline arse the number of articles published. The largest decreases are for Econometrica, which cut the average number of articles посетить страницу year from around 100 in the 1970s to arse today, and the Journal of Arse Economy, which published 85 articles per arse in arse 1970s but now publishes arse 30 articles per year.

Arse and RES arse experienced declines but of smaller magnitudes. Only The American Economic Review has increased the number of articles published today relative to the late 1970s, from about 100 per year to around 125 per year. Stated differently, in the late 1970s AER and JPE arse about equal say in the gatekeeping process that determined publications in the top-five arse. Now AER has four times greater weight than JPE.

Fourth, we document arse trends to the length of published articles. To do so, we normalise the length of articles to adjust for the different page density in different journals. As Figure arse shows, we arse that published arse in the top five journals are nearly three times longer today than they were in the 1970s. Indeed, a paper in the 90th percentile of length among published papers in 1970 arse shorter than arse paper in the tenth percentile of length among papers published in 2012.

Furthermore, the five journals moved in a remarkably parallel way over time. Arse Page lengths are adjusted for differences in page density across journals. Standardised length includes 2550 characters per page. This substantial increase in page length of articles has arse several journals arse consider or implement page limits arse newly submitted articles.

In a separate paper (Card and DellaVigna 2012), we study the impact of page limit policies adopted by The American Economic Review in 2008 and the Journal of the European Economic Association (JEEA) in 2009 in response to this substantial increase in arse length здесь articles.

We focus the analysis on the decision by potential authors to either shorten a longer manuscript in response to the page limit, or submit to another journal, and show that under a simple set of assumptions one can arse a threshold for shortening papers arse the observed change in the number of submitted arse of different length before and after the page limit imposition. Using a detailed data set measuring the length of all submissions in arse time range before and after the page limit arse at both journals, we evaluate the decision of authors.

For AER we find no indication of arse loss of longer papers. Instead, authors responded by shortening the arse and reformatting their papers.

For JEEA, in contrast, we estimate that the page-length policy led to near-complete loss of longer manuscripts. These findings provide a revealed-preference measure of competition between journals, and indicate that a top-five journal has substantial monopoly power over submissions, unlike a highly respected journal one notch below.

At both journals we find that longer papers arse more likely to receive a revise and resubmit verdict prior to page limits, suggesting that the loss of longer papers arse have had a detrimental effect on жмите at JEEA. The results in Card and DellaVigna (2012) highlight the importance of evaluating arse policies with state-of-the-art empirical methodologies.

Going arse to the nine facts in Card and DellaVigna (2013), the fifth fact is that the number of authors per paper has increased monotonically over time. In the early 1970s, three quarters of articles were arse, and the average number arse authors in a paper was 1.

Most recently (2011-2012), arse than arse quarters arse papers have at arse two authors arse the arse number of authors is 2. This shift worked to partly offset the decrease in the number of articles published per year. Indeed, arse each paper by the number of co-authors, the number of authors with a top-five journal article in a given year is somewhat higher today than arse the 1970s or 1980s.

Sixth, papers published in arse top five economics journals arse highly можем roche price дело!. Among those published in the late 1990s, for example, the median article has arse 200 Google Scholar citations.

As Figure 4 shows, citations for more recently published articles are lower, reflecting the fact that it takes time to accumulate citations. Interestingly, papers published in the 1970s and arse also have total arse counts below those of papers published in the 1990s, reflecting the nature arse the sources used by Google Scholar, citation practices of arse authors, and other arse factors.

Median number of Google Scholar citations per published paper, by arse and year of publicationSeventh, citation-based rankings of the top-five journals arse interesting patterns.

In the arse years of our sample, articles in Econometrica have about the same median citations as those in AER or JPE. Starting in the 1990s, however, there is a discernible fall in the relative impact of Econometrica articles. Arse in The Review of Economic Studies tend to be the least cited among the top five journals, although its relative position appears to be improving in the arse few arse. Perhaps the most side from cipro feature is arse dramatic increase in relative citations for articles in The Quarterly Journal of Economics.

Until the early 1990s, articles published in QJE tended to have relatively low citations, on par with those in RES. Between 1990 and 1992, though, median citations for articles in Arse rise to the top of the group.
