Not All Price Endings Are Created Equal: Price Points and Asymmetric Price Rigidity

We document an asymmetry in the rigidity of 9-ending prices relative to non-9-ending prices. Consumers have difficulty noticing higher prices if they are 9-ending, or noticing price-increases if the new prices are 9-ending, because 9-endings are used as a signal for low prices. Price setters respond strategically to the consumer-heuristic by setting 9-ending prices more often after price-increases than after price-decreases. 9-ending prices, therefore, remain 9-ending more often after price-increases than after price-decreases, leading to asymmetric rigidity: 9-ending prices are more rigid upward than downward. These findings hold for both transaction-prices and regular-prices, and for both inflation and no-inflation periods.

Popular Perceptions and Political Economy in the Contrived World of Harry Potter

Economic organization of the imaginary worlds depicted in popular literary works may be viewed as a mirror to public opinion on the economic organization of life. If a book becomes a best-seller, it is because the book conveys messages, feelings, and events the readers can relate to. In other words, the book’s readers identify with the set of norms and rules that govern the development of the plot and the actions of its heroes. Therefore, a best seller, as a book that successfully relates to readers of its time, can teach us about the norms and beliefs of its audience. Following this line of thought, we use the method of deconstruction to analyze the highly successful J.K. Rowlings’ Harry Potter series. Studying the books within their social context allows us to learn about people’s norms and attitudes, and their perceptions of issues such as the role of government, the structure of financial markets, poverty and inequality, etc. Thus, by looking at the Potterian economy through magnifying glasses, we obtain a perspective on what people might view as a normal or perhaps as an ideal economic structure. In other words, we argue, that the economic and organizational structure of the imaginary Potterian economy can be viewed as an economic model. By studying the social and the economic structure of the Potterian model and its assumptions, we hope to obtain some insights on people’s attitudes towards various social and economic issues. The Potterian economic model, we conclude, is not a coherent model that fits neatly one of the standard economic models. Instead, it appears to combine ingredients from various economic models.

End of 9-Endings and Price Perceptions

We take advantage of a natural experiment to document an emergence of a new price ending that has the same effects as 9-endings. In January 2014, the Israeli parliament has passed a law prohibiting the use of non 0-ending prices. We find that one year after 9-ending prices have disappeared, 90-ending prices acquired the same status as 9-ending prices had before the law was passed. 90-ending prices became the new psychological price points. The retailers and the shoppers both reacted to the regulatory intervention optimally, which has eliminated the regulation’s intended effect.
