Economics is not only a social science, it is a genuine science. Like the physical sciences, economics uses a methodology that produces refutable implications and tests these implications using solid statistical techniques. In particular, economics stresses three factors that distinguish it from...

The analysis of historical natural experiments has profoundly impacted economics research across fields. We trace the development and increasing application of the methodology, both from the perspective of economic historians and from the perspective of economists in other subdisciplines. We...

The past half-century has seen economic research become increasingly empirical, while the nature of empirical economic research has also changed. In the 1960s and 1970s, an empirical economist's typical mission was to “explain” economic variables like wages or GDP growth. Applied...

Does academic economic research produce material of scientific value, or are academic economists writing only for clients and peers? Is economics scholarship uniquely insular? We address these questions by quantifying interactions between economics and other disciplines. Changes in the impact of...

Replication is a critical component of scientific credibility as it increases our confidence in the reliability of the knowledge generated by original research. Yet, replication is the exception rather than the rule in economics. In this paper, we examine why replication is so rare and propose...

In the United States today the academic field of economic history is much closer to economics than it is to history in terms of professional behavior, a stylized fact that I call the “integration of economic history into economics”. I document this using two types of evidence – use of...

Over the last six decades articles published in leading economic history journals have been less likely to be co-authored than articles published in leading general economics journals. However, in both economic history and general economics journals there have been strong, monotonic increases in...

Over the last three decades there has been a dramatic increase in the length of time necessary to publish a paper in a top economics journal. This paper documents the slowdown and notes that a substantial part is due to an increasing tendency of journals to require that papers be extensively...

We study how citation patterns differ between journal tiers in economics. Concretely, we analyze citations patterns of more than 6,000 economics research articles published in top five, second tier, and top field economics journals between 1992 and 1996. In line with previous literature, we find...

This paper examines the relationship between placement of publications in Top Five (T5) journals and receipt of tenure in academic economics departments. Analyzing the job histories of tenure-track economists hired by the top 35 U.S. economics departments, we find that T5 publications have a...
