We ask how far the choice of which moments to match can push estimates in misspecified structural models. The answer is: very far. Under regularity conditions, an adversarial researcher informed about ...

Abstract: In this article we introduce an approach for modeling and analyzing collective behavior of a group of agents using moments. We represent the group of agents via their distribution and derive ...

When Mr Ryan Vernados first began volunteering at an orphanage in his home town in Indonesia as part of a class activity, the experience was more like an obligation than a calling. It felt like a ...

The Riemann hypothesis is the most important open question in number theory—if not all of mathematics. It has occupied experts for more than 160 years. And the problem appeared both in mathematician ...

Lent is a 46-day period (40 regular days plus six Sundays) in the Christian liturgical calendar meant to commemorate Jesus’s 40-day fast in the wilderness. It spans from Ash Wednesday until Easter ...

SINGAPORE - Very few countries in the world are well placed to seize the opportunities that come from longer lifespans of their population. Among the biggest barriers are ageism and lack of good ...

Solving or attempting to solve problems is the typical and, hence, general function of thought. A theory of problem solving must first explain how the problem is constituted, and then how the solution ...

Abstract: In this paper, a discontinuous Galerkin time-domain (DGTD) method is developed to simulate high-power microwave air breakdown phenomena, which is modeled by a coupled electromagnetic-plasma ...

Partial differential equations (PDEs) are among the most ubiquitous tools used in modeling problems in nature. However, solving high-dimensional PDEs has been notoriously difficult due to the “curse ...

When we first meet Ron Swanson on Parks and Recreation he’s explaining his distaste for government work (Chuck E. Cheese has a better business model, in his opinion). His office is decorated with a ...
