Wage growth globally continued to slow over the past few years. In 2013, wages were unable to keep up with a 3.9% inflation rate. In developing economies wages increased from 0.1-0.2%. As a result, demand for goods and services have declined along with wage declines. This has resulted in high unemployment and numerous recessions.
