Recent studies in psychology and neuroscience offer systematic evidence that fictional works exert a surprisingly strong influence on readers and have the power to shape their opinions and worldviews. Building on these findings, we study "Potterian economics", the economic ideas, insights and...

Recent studies in psychology and neuroscience find that fictional works exert strong influence on readers and shape their opinions and worldviews. We study the Potterian economy, which we compare to economic models, to assess how Harry Potter books affect economic literacy. We find that some...

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,...

Contractual restrictions on mobility of workers across units within a franchise – “no-poaching” clauses – have recently attracted attention. The restrictions are claimed to concentrate labor markets to the detriment of employees. Previous research has found that they do. However,...

Prices that end with 9, also known as psychological price points, are common, comprising about 70% of the retail prices. They are also more rigid than other prices. 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...

The price system, the adjustment of prices to changes in market conditions, is the primary mechanism by which markets function and by which the three most basic questions get answered: what to produce, how much to produce and for whom to produce. To the behaviour of price and price system,...

Analyzing a large weekly retail transaction price dataset, we uncover a surprising regularity - small price increases occur more frequently than small price decreases for price changes of up to about 10 cents, while there is no such asymmetry for larger price changes. The asymmetry holds for the...

Item pricing laws (IPLs) require a price tag on every item sold by a retailer. We study IPLs and assess their efficiency by examining and quantifying their costs and comparing them to their measurable benefits. On the cost side, we posit that IPLs should lead to higher prices because they...

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...

The literature on costs of price adjustment has long argued that changing prices is a complex and costly process. In fact, some authors have suggested that we should think of firms' price-setting activities as "producing" prices, similar to the way firms use production processes to produce goods...
