Purpose

The purpose is to detect the nonlinearity wholesale rice price formation process in Italy in the 1995–2017 period.

Design/methodology/approach

A nonlinear smooth transition autoregressive (STAR)-type dynamics model is used.

Findings

Wholesale rice prices are significantly affected by variations in the international price of rice as well as variations in Arborio price.

Research limitations/implications

The limitations include policy recommendations for the production and commercialization of rice in Italy.

Practical implications

Understanding rice pricing dynamics and nonlinearity behavior is pivotal for the survival of the entire European and Italian rice supply chain.

Originality/value

In the extant literature, no evidence exists on non-linearity of rice prices in Italy.
