and where the first inequality follows from the definition (2) of the weak-learning condition. Let λ∗ be a minimizer of the min-max expression. Unless the first entry of each-row of (Hλ∗ −B) is the largest, the right hand side of the min-max expression can be made arbitrarily large by choosing C ∈ Ceor appropriately. For example, if in some row i, the j0th element is strictly larger than the fi...

In this paper, we present the Black blogosphere’s discussion of the Jena 6 case to uncover how ethnic identity is performed discursively to promote social activism. Historically, African Americans have used radio for communication about critical issues, such as political elections, health care, education, economic development and civil rights. More recently with the growing popularity of blogs ...

This paper examines the implications of human capital risk for the relationship between inequality and economic development. It argues that due to missing insurance markets for human capital risk, the initial distribution of family wealth may play an important role for an economy’s process of development fueled by human capital accumulation. The analysis suggests that, in the absence of credit ...

In the standard Simon task, participants carry out spatially defined responses to non-spatial stimulus attributes. Responses are typically faster when stimulus location and response location correspond. This effect disappears when a participant responds to only one of the two stimuli and reappears when another person carries out the other response. This social Simon effect (SSE) has been consid...

Observers often judge agents who miss a desired outcome by a small, compared to a large, margin to be less happy. This nearmiss effect has typically been examined in situations where the agents have control over outcomes (e.g., missing a flight). Here, we extend this work in three ways. First, we show that near-miss effects play into observers’ intuitive theories of emotion even for randomly-de...

Meta-analytic methods have been widely applied to education, medicine, and the social sciences. Much of meta-analytic data are hierarchically structured because effect size estimates are nested within studies, and in turn, studies can be nested within level-3 units such as laboratories or investigators, and so forth. Thus, multilevel models are a natural framework for analyzing meta-analytic da...

This research suggests that the distribution of land within and across countries affected the nature of the transition from an agrarian to an industrial economy generating diverging growth patterns across countries. Land abundance, which was beneficial in early stages of development, generated in later stages a hurdle for human capital accumulation and economic growth among countries in which l...

We examine how aggregate output and income distribution interact with accumulation of intangible capital over time and across individuals. We consider an overlapping generations economy in which managerial skill (intangible capital) is essential for production, and it is acquired by young workers through on-the-job training by old managers. We show that, when young trainees are not committed to...

This paper explores the world of social media as a tool for interactive narrative in video games. From the perspective of fan fiction, this paper looks at ways games can be transformed through Twitter as a narrative tool. We perform a textual analysis on selected characters’ Twitter accounts drawn from the Mass Effect series. We show a number of findings having to do with how authors balance th...

We estimate the effect of pension reforms on households’ expectations of retirement outcomes and wealth accumulation decisions exploiting a decade of pension reforms as a source of exogenous variation in expected pension wealth. Two parameters are crucial to estimate pension wealth: the age at which workers expect to retire and the expected ratio of pension benefits to pre-retirement income. Th...
