International Econometric Review (IER), sponsored by the Econometric Research Association (ERA), is an independent international journal which publishes quarterly. It is an open access journal. IER is indexed and abstracted in EconLit, DOAJ, EBSCOhost, RePEc, Sobiad and Ulrich. The journal applies double bilind peer review process for papers. IER has recently modified and expanded its scope, as indicated by the subtitle "21st Century Economics". We seek to publish high quality papers in new fields of research in all areas of economics. The article "New Directions in Macroeconomics" lists the many areas of Macro which are of interest. In Microeconomics, we are interested in behavioral, experimental and heuristics of decision making. We are also interested in the large scale experiments pioneered by Duflo and Banerjee. In Econometrics, we would like to see papers in Causality, Data Visualization, Big Data Techniques, especially Machine Learning, as well as many other emerging fields. Briefly, we would like to see research in new areas, outside the scope of traditional Micro, Macro and Econometrics of the 20th Century.
