In this article we reply to C. J. Ferguson and J. Kilburn’s (2010) critique of our meta-analysis on violent video game effects (C. A. Anderson et al., 2010). We rely on well-established methodological and statistical theory and on empirical data to show that claims of bias and misinterpretation on our part are simply wrong. One should not systematically exclude unpublished studies from meta-ana...

Hypothetical estimates of willingness to pay tend to overstate real willingness to pay. Several methods to mitigate this so called hypothetical bias have been developed. This paper contributes by presenting the first simultaneous comparison of three common hypothetical bias mitigation methods as well as their interactions. In addition, the study represents the first use of the contingent valuat...

Here we study polysemy as a potential learning bias in vocabulary learning in children. We employ a massive set of transcriptions of conversations between children and adults in English, to analyze the evolution of mean polysemy in the words produced by children whose ages range between 10 and 60 months. Our results show that mean polysemy in children increases over time in two phases, i.e. a f...

Regulators, investors, consumers, and insurance brokers use insurer financial strength ratings to evaluate the insolvency risk of insurers. This article investigates the factors influencing the decision to obtain a rating or multiple ratings, the determinants of ratings for the three major insurer rating agencies, and reasons for differences in ratings across agencies. This study indicates that...

A long standing question in radio astronomy has been why some elliptical galaxies host strong radio sources and others not. The reason may have something to do with the physical conditions near the (active) nucleus from which the radio source emanates. The resolution of HST images is such that dust features close to the nucleus can be detected, and these may often be in the form of circumnuclea...

Data on over 7,000 offenders were collected to evaluate the impact of industrial work experience and vocational and apprenticeship training on in-prison and post-release outcomes. Prior research on prison training outcomes failed to find any significant training effects. Related research on the economic conditions faced by ex-offenders has demonstrated the difficult conditions under which these...

Significant difference between response to real and hypothetical valuation questions is often referred to as hypothetical bias. Some economists have had success with using “cheap talk” (which entails reading a script that explicitly highlights the hypothetical bias problem before participants make any decisions) as a means of generating unbiased responses in a referendum format. In this article...

Reforms and Productivity Dynamics in Chinese State-Owned Enterprises Institutional change has taken place gradually since 1978 for State-Owned Enterprises (SOEs) in the Industrial Sector of China. In this paper we estimate the effect of deep reform (the right to hire and fire labour, buy and sell capital and operate on international markets) on the productivity dynamics of enterprises. Using a ...
