The prices accepted by consumers in the market are influenced by the characteristics of the goods, based on consumer behavior. Each of these features contributes to the price agreed upon by both consumers and suppliers. The packaging of a product plays a crucial role in attracting consumers and protecting the product from damage. High-quality and visually appealing packaging can create a positive perception among consumers, potentially resulting in a higher price point. Additionally, specialized packaging techniques designed to preserve freshness and extend the shelf life of oil can also impact the price. This study investigates the impact of quality and packaging on the price of sunflower oil in Iran. The primary objective was accomplished using the hedonic pricing method. Given the qualitative and ordinal nature of the dependent variable, the ordinal logit model was employed. The sample size was determined through a two-stage cluster sampling approach, which involved collecting 350 questionnaires from consumers in Tehran city. Statistical analysis was conducted using Shazam and Stata software. Numerous factors influence the consumption of sunflower oil at various levels. However, in general, factors such as increasing age, higher income levels, the presence of diseases, and dietary considerations contribute to a decrease in its consumption. On the other hand, factors like improving product quality, enhancing the quality of oil packaging, increasing consumer loyalty towards edible oil, and rising online sales of this product contribute to an increase in its demand.

This paper investigates the responses of Iran’s macroeconomic variables to the oil embargo against Iran. The article applies a Bayesian time-varying parameter SVAR model along the quarterly data of oil export, real exchange rate, inflation, real GDP and money supply of Iran over the period of 1991:Q2-2020:Q2. Applying time varying parameters in this study helps us to consider the economic structural changes and transition mechanism in analyzing the response of macroeconomic variables to oil embargo. The oil embargo against Iran has been intensified since 2012. To consider the effect of the oil embargo on Iranian macro variables, the model has been estimated in two different periods of time, before and after 2012. The results indicate that the escalation of the oil embargo from 2012 has caused a stagflation period and ends in a decline in real GDP and national currency depreciation. In addition, it has intensified money supply and triggers existing inflation. These results have some policy implications to overcome difficulties raises when the economy faces sanction.
