In April 2009, we introduced a model representing the evolution of motor fuel price (a subcategory of the consumer price index of transportation) relative to the overall CPI as a linear function of time. Under our framework, all price deviations from the linear trend are transient and the price...

Previously, linear trends were revealed in the differences between the headline CPI and the price indices for various subcategories of the CPI in the United States. These trends can be continuous, as observed with the price index for medical care, or piecewise with turning points between trends...

It was demonstrated that the difference between the PPI of durable and nondurable goods can be predicted at a several year horizon. The prediction consists of three steps. First, we show that the difference between producer price index for durable and nondurable goods is characterized by the...

It was demonstrated that gold ores price can be predicted at a several year horizon. The prediction consists of three steps. First, we show that the difference between producer price index and the index for gold ores is characterized by the presence of sustainable mid-term trends. Second, the...

It was demonstrated that jewelry and jewelry products price can be predicted at a several year horizon. The prediction consists of three steps. First, we show that the difference between producer price index and the index for jewelry and jewelry products is characterized by the presence of...

We present a five-year revision of an empirical study started in 2007. Seven years ago, we found two three distinct periods characterized by sustainable linear trends in the difference between the headline consumer price index (CPI) and the core CPI in the USA. Then we revealed similar behavior...
