Abstract
The main goal of this work is to propose a general methodology to create a coincident index for the economy of a given country or region based on linear combinations of dynamic common factors, and to validate it on simulated scenarios and on a case study for Colombia. The methodology proposed can effectively handle both stationary and nonstationary macroeconomic variables as input and provides tools to obtain point estimates and confidence regions, and to test hypotheses for the linear-combination coefficients. This work highlights how promising this new proposal is in terms of its contribution with respect to its antecedents in the literature, by showcasing situations in which a linear combination of dynamic factors can enhance the accuracy of the nowcast and address potential problems and limitations of considering only one dynamic factor as index. The application of this work to the Colombian economy is based on the macroeconomic analysis conducted by previous researchers. This work, however, considers and analyzes a much larger set of candidate indices via linear combinations of factors, providing consistent results; which strengthens and validates their previous findings.
