Determinants of the Frequency of Price Changes in Vietnam

The paper aims to study the determinants of price stickiness proxied by the frequency of price changes in Vietnam by using the Poisson regression model with survey data. We find that the frequency of price changes is positively and negatively related with firms’ choice of time dependence and rule of thumb, respectively. Importantly, we also reveal that the coordination failure, the existence of contracts and temporary shocks are the three most important reasons for price rigidity. Finally, we find the degree of competition, firm size, the share of state ownership, quantity discount practice, sales destination and market share all matter for how often firms adjust their prices.
