The study looked at how prices are set in Slovakia, an emerging economy, using a large dataset. They found that market structure plays a big role in how prices change over time. More competition can lead to prices changing more often, but it can also make prices stick around longer. In Slovakia, higher competition actually made prices more spread out and less persistent in certain sectors. The frequency of price changes was influenced by how different prices were from each other and how much inflation affected specific products. These findings match up with a well-known model of how prices change over time.
