1. An apparatus comprising: an early warning system; an electronic processing device; and a memory device storing computer readable instructions that, when executed by the electronic processing device, cause the apparatus to: receive economic data for a plurality of time series, wherein each member of the plurality of time series corresponds to a different geographical entity; determine auto regressive model coefficients for the economic data of the plurality of time series; determine, for a first member of the plurality, a first scaled lag-1 auto-correlation of the coefficients; determine, for the first member, a first scaled smoothed derivative from the first scaled lag-1 auto-correlation of the coefficients; output, for the first member, a first indicator based on the first scaled smoothed derivative; generate, by the early warning system based on at least the first indicator for a first member of the plurality of time series, an early warning signal, wherein the first member corresponds only to a first geographical entity and wherein the early warning signal comprises an early warning notification and detailed information about a potential instability of the economic data; determine a set of registered computing devices associated with the first geographical entity, wherein the set includes a first device and a second device; send the early warning notification about the first geographical entity to the first device and second device; when an acknowledgment of the early warning notification is received from the first device, initiate launching of an early warning application at the first device; and send the detailed information about the potential instability to the first device via the early warning application.
