Moving discontinuity plots
The graphs plot moving discontinuity estimates for the 10, 5 and 1 percent significance level for k = 15 years time windows. Each dot is the result of a single discontinuity estimation. The x-axis marks the end point of the respective intervals. For example, the first dot reports the estimate for the interval 1959–1973, the second dot reports the estimate for the interval 1960–1974, and so forth. The outer lines denote the 95% confidence interval. The estimates are reported in Table 2.

While publication bias has been widely documented in the social sciences, it is unclear whether the problem aggravated over the last decades due to an increasing pressure to publish. We provide an in-depth analysis of publication bias over time by creating a unique data set, consisting of 12340 test statistics extracted from 571 papers published in...
