Titel: Evidence-Based Economics. Issues and Some Preliminary Answers
Autor: Julian Reiss
Abstract: This paper presents an outline of a methodology of ?evidence-based economics?. The question whether an economic statement is evidence-based must be answered on three different levels. The first level concerns measurement: it asks whether claims made about economic quantities such as inflation, unemployment, growth or poverty are justified by the data and measurement procedures. The second level concerns induction: it asks whether claims made about the relations between economic quantities (such as ?number of babies born predicts growth?, ?change in money causes change in monetary income?, ?non-borrowed reserves can be used to control the interest rate?), are justified by the inference procedures. The third level concerns idealisation: it asks whether the quantities and relations selected are justified by the stated aim of the inquiry. The paper provides a discussion of these three types of investigation and of some solutions that have been offered.

Many feel that precision and mathematisation are bought at a price too high, namely unrealistic assumptions, empty models with little or no explanatory power, unreliable predictions and a general state of...
