Laboratory measure of cheating predicts school misconduct
Laboratory experiments provide insights into the drivers of cheating behaviour, but it is unclear to what extent cheating in the lab generalizes to the field. We conducted an experiment with middle and high school students to test whether a common laboratory measure of cheating predicts three types of school misconduct: (i) disruptiveness in class, (ii) homework non-completion, and (...

Optimal search from multiple distributions with infinite horizon
With infinite horizon, optimal rules for sequential search from a known distribution feature a constant reservation value that is independent of whether recall of past options is possible. We extend this result to the the case when there are multiple distributions to choose from: it is optimal to sample from the same distribution in every period and to continue searching until a...

A note on the analysis of two-stage task results: how changes in task structure affect what model-free and model-based strategies predict about the effects of reward and transition on the stay probability
Many studies that aim to detect model-free and model-based influences on behavior employ two-stage behavioral tasks of the type pioneered by Daw and colleagues in 2011. Such studies commonly modify existing two-stage decision paradigms in order to better address a given hypothesis, which is an important means of scientific progress. It is, however, critical to fully appreciate the...

This paper studies whether the use of a competitive pricing mechanism reduces such wasteful activities. We report data from a laboratory experiment where a powerful buyer can trade with one of two sellers—an environment that can lead to very low prices for the sellers. We find...

Expectation and experience: : passenger acceptance of autonomous public transportation vehicles
Passenger acceptance is a key factor for the successful integration, uptake and use of autonomous vehicles (AVs) in the domain of public transpor-tation. Especially knowing opinions and attitudes around safety, comfort and convenience. We discuss a pilot study conducted as part of a larger research project where AVs are being tested to transport members of the general public on a...

Multi-scale and multi-directional biomedical texture analysis: : finding the needle in the haystack
This chapter clarifies the important aspects of biomedical texture analysis under the general framework introduced in Chapter 1. It was proposed that any approach can be character-ized as the combination of local texture operators and regional aggregation functions. The type of scale and directional information that can or cannot be modeled by categories of texture processing methods...

The paper analyzes, within the context of a DSGE model, the hedging properties of foreign bond and foreign equity holdings during a crisis, when the degree...

Numerical implementation of the QuEST function
Certain estimation problems involving the covariance matrix in large dimensions are considered. Due to the breakdown of finite-dimensional asymptotic theory when the dimension is not negligible with respect to the sample size, it is necessary to resort to an alternative framework known as large-dimensional asymptotics. Recently, an estimator of the eigenvalues of the population...

The welfare effects of vertical integration in multichannel television markets
We investigate the welfare effects of vertical integration of regional sports networks (RSNs) with programming distributors in U.S. multichannel television markets. Vertical integration can enhance efficiency by reducing double marginalization and increasing carriage of channels, but can also harm welfare due to foreclosure and incentives to raise rivals' costs. We estimate a...
