Many of us believe that if some acts wrongly out culpably ignorance, they are morally blameworthy to degree. I offer a defense this view against the powerful "Liberal Challenge" position.

It is a common fear in many countries that ideological parties will come to power through elections but will implement extreme policies. Many countries cope with this problem by overriding the election results when such parties are elected. We demonstrate that the alternative approach of containing these parties within the democratic system is more effective. We show that, as the probability of...

Content moderation systems for social media have had numerous issues of bias, in terms race, gender, and ability among many others. One proposal addressing such automated decision making is by designing contestability, whereby users can shape influence how decisions are made. In this study, we conduct a series participatory design workshops with participants from communities that experienced pr...

CSCL learning environments provide new contexts for discussions and are thought to provide new opportunities for learning. At the same time, such environments often do not provide guidance on how to act during the discussion. The purpose of this paper is to initiate research on moderation in synchronous discussions in a CSCL environment. The first study contrasts teachers' beliefs on good discu...

We study how total factor productivity (TFP), energy prices, and the Great Moderation are linked. First we estimate a joint stochastic process for the energy price and TFP and establish that until the second quarter of 1982, energy prices negatively affected productivity. This spillover has since disappeared. Second, we show that within the framework of a dynamic stochastic general equilibrium ...
