Experimental Data: Price Perceptions After Euro Adoption

We present data on whether inviduals can discern conversion-driven price hikes in the situation of simulteneously using two currencies. A sample of 296 subjects are presented with a shopping receipt with prices of individual items in both Euro and Bulgarian leva, as well as the fixed exchange rate between the two currencies; and then asked to state their preference in paying the original or the euro-converted price. However, conversion is imperfect, with the price in Euro being slightly higher (3-8% in different conditions). We also measure their trust in the merchant as well as various demographic and behavioral factors such as age, gender, usage of online media, trust in institutions and others. The dataset can be used to study how populations will react to conversion-induced inflation in countries that change their currency to a new one, such as the prospective Eurozone members. Data was collected in early 2023 among a sample of Sofia University students and amid public discussion and planning about the adoption of the Euro. Key findings indicate that small conversion errors on the upside go unnoticed by individuals, which is a mechanism for generating inflation pressures at the macroeconomic level.

本研究所呈现的数据集涉及个体在同时使用两种货币的情况下，能否辨别由转换引起的价格涨幅。该数据集包含296名受试者，他们被呈现一份包含单个商品价格同时以欧元和保加利亚列弗标价的购物收据，以及两种货币之间的固定汇率；随后，研究者要求他们表明是愿意支付原始价格还是欧元转换后的价格。然而，由于转换存在细微误差，欧元价格在不同条件下略高（3-8%不等）。此外，我们还测量了他们对商家的信任度，以及诸如年龄、性别、在线媒体使用情况、对机构的信任度等其他人口统计学和行为因素。该数据集可用于研究人口在货币更替至新货币（如潜在欧元区成员国）时，对由转换引起的通货膨胀的反应。数据收集于2023年初，对象为索非亚大学的学生，当时正值关于欧元采纳的公共讨论和规划。关键发现表明，个体对向上微小的转换误差未予察觉，这是在宏观经济层面产生通货膨胀压力的机制。
