The financial statement (FS) fraud detection framework proposed in this paper, PeerMeta, makes improvements in all three aspects of learning processes: the selection of research samples, feature set, and detection model. For the research samples, prior studies are based on FS fraud events that...

Why and when do legislators vote together on policy? Do legislators decide to vote similarly mainly because of social influence or similarity? I contribute to the literature by offering a social network theory of voting. It is argued that close social ties help to establish reputations and aid...

Various empirical papers have shown that peers affect productivity and behavior in the workplace. However, the mechanisms through which peers influence each other are still largely unknown. In this laboratory experiment we study a situation in which individuals might look at their peers'...

The credible identification of endogenous peer group effects - i.e., social multiplier or feedback effects - has long eluded social scientists. We argue that such effects are most credibly identified by a randomly assigned social program which operates at differing intensities within and between...

We use idiosyncratic variation in gender composition across cohorts within Norwegian lower-secondary schools to analyze the impact of female peers on students’ grades and choices of typical masculine subjects (STEM subjects). We find that girls’ performance in mathematics and science...

This paper studies the educational consequences of language proficiency by investigating the relationship between dialect-speaking and academic performance of 5-6 year old children in the Netherlands. We find that dialect-speaking has a modestly negative effect on boys' language test scores. In...

Culture shapes economic behavior and colors economic outcomes. Although we may choose to avoid explicitly discussing culture within the social sciences, it will be implicit in our assumptions. The question, then, becomes how to incorporate culture into economic analysis. Some economists have...

Social interactions are widely recognized to play an important role in smoking initiation among adolescents. In this paper we hypothesize that individual with `stronger' personalities (i.e. emotionally stable, conscientious individuals) are better able to resist peer pressure in the uptake of...

The influence of peer effects on the diffusion of innovations has been extensively studied. However, the underlying mechanisms of peer effects are generally understudied. Gaps in this knowledge could lead to misestimation of peer effects and inefficient interventions. This study examined the...

We examine how adoption of a high-value crop diffuses through social networks, using detailed demographic, social network, and adoption data from ten villages in Central China. We develop a model of diffusion through a multiplex network that distinguishes the influence of sharing experiential...
