Returns to scale with a Cobb-Douglas production function for four small Northern Italian firms

Osti, Davide - 2022

With this piece of evidence, I try to shed light upon the effects of fixed and variable costs on revenues for four firms operating in the sectors of lathing and milling, packaging machine construction, mechanical component production and shoe parts building, all four in the vicinity of Bologna,...

Pricing Better

Ray, Sourav; Wang, Li; Levy, Daniel; Bergen, Mark - 2019

Electronic shelf label (ESL) is an emerging price display technology around the world. While these new technologies require non-trivial investments by the retailer, they also promise significant operational efficiencies in the form of savings in material, labor and managerial costs. The presumed...

Not all price endings are created equal: Price points and asymmetric price rigidity

Levy, Daniel; Snir, Avichai; Gotler, Alex; Chen, Haipeng - 2019

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...

If You Think 9-Ending Prices Are Low, Think Again

Snir, Avichai; Levy, Daniel - 2019

9-ending prices are a dominant feature of many retail settings, which according to the existing literature, is because consumers perceive them as being relatively low. Are 9-ending prices really lower than comparable non 9-ending prices? Surprisingly, the empirical evidence on this question is...

If You Think 9-Ending Prices Are Low, Think Again

Snir, Avichai; Levy, Daniel - 2019

9-ending prices, which comprise between 40%–95% of retail prices, are popular because shoppers perceive them as being low. We study whether this belief is justified using scanner price-data with over 98-million observations from a large US grocery-chain. We find that 9-ending prices are higher...

Some Identification Issues in Nonparametric Linear Models with Endogenous Regressors

Severini, Thomas A.; Tripathi, Gautam - 2005

, such as a regression function, and treating it as a conditional expectation is central to its identification and estimation … identification related properties of this model when the unknown function mu* belongs to a linear space. We also investigate … underidentification of mu* along with the identification of its linear functionals. Several examples are provided in order to develop …

Sparse Linear Models and l1−Regularized 2SLS with High-Dimensional Endogenous Regressors and Instruments

Zhu, Ying - 2015

We explore the validity of the 2-stage least squares estimator with l_{1}-regularization in both stages, for linear regression models where the numbers of endogenous regressors in the main equation and instruments in the first-stage equations can exceed the sample size, and the regression...
