Your Right Arm for a Publica3on in AER?

Abstract: The Wme tradeoff (TTO) method is popular in medical decision making for valuing health states. We use it to elicit economists’ preferences for publishing in top economic journals and living without limbs. The economists value the journals highly, and have a clear preference between them, with American Economic Review (AER) the most preferred. Their responses imply they would sacrifice more than half a thumb for publishing in AER. The TTO results are consistent with ranking and willingness to pay results, and indicate that preferences for journals are neither guided by influence factors, nor by expectaWons of a resulWng salary rise. Number of Pages in PDF File: 22 Keywords: UWlity Measurement, Time Tradeoff, Willingness to pay, PublicaWons JEL ClassificaWons: A10, B41, I10 h7p://ssrn.com/abstract=997122

InsWtuWonal Repository Good And Bad
GOOD Excellent for institutions with the vision, commitment, and resources for the long-haul Possibly the only alternative for smaller subject areas without a DR Provide institutional control and the “possibility” to change scholarly publishing in the future
BAD Costs are almost always underestimated Potential for archival loss
To a7ain knowledge, add things every day. To a7ain wisdom, subtract things every day.

The Effect of Free Access on the Diffusion of Scholarly Ideas
Heekyung Hellen Kim MIT Sloan School of Management
Abstract: This study examines a relaWonship between free access to research arWcles and the diffusion of their ideas as measured by citaWon counts. While free access should, in theory, help the diffusion of ideas, many researchers have debated the existence of the benefit of free access: reported empirical findings range from zero or negaWve effect to an over 300% increase of citaWons of non-‐free arWcles. By using a dataset from the Social Science Research Network (SSRN), an open repository of research arWcles, and employing a natural experiment that allows the esWmaWon of the value of free access separate from confounding factors such as early viewership and quality differenWal, this study idenWfies the causal effect of free access on the citaWon counts. The natural experiment in this study is that a select group of published arWcles is posted on SSRN at a Wme chosen by their authors’ affiliated organizaWons or SSRN, not by their authors. Using a difference-‐in-‐difference method and comparing the citaWon profiles of the arWcles before and aner the posWng Wme on SSRN against a group of control arWcles with similar characterisWcs, I esWmated the effect of the SSRN posWng on citaWon counts. The arWcles posted on SSRN receive more citaWons even prior to being posted on SSRN, suggesWng that they are of higher quality. Their citaWon counts further increase aner being posted, gaining an addiWonal 10-‐20% of citaWons. This gain is likely to be caused by the free access that SSRN provides.
