There is evidence that 9-ending prices are more common and more rigid than other prices. We use data from three sources: a laboratory experiment, a field study, and a large U.S. supermarket chain, to study the cognitive underpinning and the ensuing asymmetry in rigidity associated with 9-ending...

We study the link between price points and price rigidity, using two datasets containing over 100 million observations. We find that (i) 9 is the most frequently used price-ending for the penny, dime, dollar and ten-dollar digits, (ii) 9-ending prices are between 24%-73% less likely to change in...

In this paper, we analyze the economic structure of the world of wizards as depicted in the Harry Potter books, which we term Potterian economy, and offer an economist's perspective on it. We look at the economic structure of the life of Harry Potter and his co-actors as an economic model that...

If producers have more information than consumers about goods' attributes, then they may use non-price (rather than price) adjustment mechanisms and, consequently, the market may reach a new equilibrium even if prices remain sticky. We study a situation where producers adjust the quantity (per...

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 bestseller, it is because the book conveys messages, feelings, and events the readers can relate to. In other...

This note outlines: 1) Why sigma-convergence may not accompany beta-convergence; 2) Cites evidence of beta-convergence in the U.S.; 3) Demonstrates that sigma-convergence does not hold across the U.S. or within most U.S. states; and 4) Demonstrates the robustness of this finding to increases in...

We use U.S. county-level data (3,058 observations) from 1970 to 1998 to explore the relationship between economic growth and the size of government at three levels: federal, state, and local. Using 3SLS-IV estimation we find that the size of federal, state, and local government all either...

The marketplace, along with its price system, is the single most important institution in a western-style free enterprise economy. The ability of prices to adjust to changes in supply and demand conditions enables the market to function efficiently and lies behind the magical invisible hand...

We use U.S. county-level data consisting of 3,058 observations, to study growth determination and measure the speed of income convergence. County-level data are particularly valuable for studying convergence because they allow us to study a sample with substantial homogeneity and exceptional...
