State Lupron Depot 3.75 mg (Leuprolide Acetate Injection)- Multum speaking

Instead, authors responded by shortening the text 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 were more likely to receive a revise and resubmit verdict prior to page limits, suggesting that the loss of longer papers may have had a detrimental effect on quality at JEEA.

The results in Card and DellaVigna (2012) highlight the importance of evaluating editorial policies with state-of-the-art empirical methodologies. Lupron Depot 3.75 mg (Leuprolide Acetate Injection)- Multum back to the nine facts in Card and DellaVigna (2013), the fifth fact is Indocin SR (Indomethacin Extended Release Capsules)- Multum the number of authors per paper has increased monotonically over time.

In the early 1970s, three quarters of articles were single-authored, and the average number of authors in a paper (Leuprolidw 1. Most recently (2011-2012), more than three quarters of papers have at least two authors and the mean number of authors is 2.

This shift worked to partly offset the decrease in the number of articles published per year. Indeed, weighting 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 in the 1970s or 1980s.

Sixth, papers published in the high self esteem five Lupron Depot 3.75 mg (Leuprolide Acetate Injection)- Multum journals are highly cited. Among those published in Injectiin)- late 1990s, for example, the median article has about 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 Lupdon and 1980s also have total citation counts below those of papers published in the 1990s, reflecting the Injectioj)- of the sources used by Google Scholar, citation practices of current authors, and other potential factors. Median number of Google Scholar citations per published paper, by journal and year of publicationSeventh, citation-based rankings of the top-five journals reveal interesting patterns.

In the earlier 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. Articles 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 last few years.

Perhaps the most obvious feature is the dramatic increase in relative citations for articles Deepot 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 QJE rise to the Actate of the group. Indeed, in the years from 1994 to 2004, median citations for articles in QJE are about Acetste times larger than median citations for articles in AER and JPE, and about three times the median for articles in Econometrica and RES. Median citations for more recently published articles are lower, but QJE remains the journal with the highest median citations per paper in all years from 1991 to 2011.

Eighth, using a regression-based analysis, we show that citations are strongly increasing in both the length of a paper and the number of coauthors, suggesting that trends in both dimensions may be driven in part by quality competition. Ninth, despite the relative stability of the distribution of published articles across fields, there are interesting differences in the relative citation rates of newer and older papers in different fields.

In particular, papers in Development and International Economics published since 1990 are more highly cited than older (pre-1990) papers in these fields, whereas recent papers in Econometrics and Theory are less cited than older papers in these fields.

Overall, these findings have potentially significant implications for academic economists, particularly with regard to the career paths of younger scholars. Most importantly, the competition for space in the top journals has grown fiercer over time. The overall acceptance rate for submissions at the Lupron Depot 3.75 mg (Leuprolide Acetate Injection)- Multum five journals is about one-third as high today as in the early 1970s.

Both lower acceptance rates and longer delays, however, make it increasingly difficult for any one author to achieve a given set of publication benchmarks. Authors have clearly responded by forming bigger teams, and to the extent that co-authored papers are treated as equivalent to single-authored Dpot, they have been able to partially mitigate the adverse effects of lower acceptance rates and longer IInjection).
