This essay considers the relation between two aims of economics: prediction and explanation. It presents an argument for the covariance thesis, the intuitive claim that predictive and explanatory performances of economic model covary under certain circumstances. The covariance thesis captures the intuition that prediction and explanation are inherently connected: If the relevant independent variables in the model allow for prediction and explanation and the inclusion of more independent relevant variables increases both performances of the model, the performances will covary. A central question of the essay is what constitutes an explanation in economics and different approaches are presented. Finally it is argued that the intuition behind the covariance thesis is in line with Hempel's symmetry thesis.
