On Bending in the As‐Rigid‐As‐Possible Deformation Energy

Computer Graphics Forum, EarlyView.
Abstract The well‐established As‐Rigid‐As‐Possible (ARAP) energy has various forms. For surface deformation, commonly used energies contain an implicit bending penalty. We present a natural, continuous generalization that incorporates multiple ARAP versions with an implicit, user‐controllable bending penalty.

Tangent Blow‐Ups for Processing Non‐Manifold Geometry

Computer Graphics Forum, EarlyView.
Abstract Many geometry processing pipelines implicitly assume their input data is a manifold, or is sampled from one, with a unique tangent plane at every point. Geometric data, however, routinely contains sharp features like edges, corners, self‐intersections, branching junctions, and other singularities, rendering standard methods ill‐defined at ...

Ethnic Groups' Access to State Power and Group Size

Economics &Politics, EarlyView.
ABSTRACT Ethnic‐based political inequality is widespread, yet its underlying drivers remain poorly understood. This paper shows that an ethnic group's relative size is a key correlate of its access to central executive power. Using data on 575 groups across 181 countries from 1946 to 2021, and restricting attention to non‐dominant groups, I document a ...

Kant's Solution to the Trilemma of Concept Formation

European Journal of Philosophy, EarlyView.
Abstract According to a widespread assumption, Kant's logical account of concept formation starts with comparison, where the latter involves concepts. On this assumption, the formation of a concept presupposes other concepts, so that the argument is threatened either by circularity, regress, or break‐off.

Measuring Bubbles via Put‐Call Disparity: A Model‐Free Approach

Financial Management, EarlyView.
ABSTRACT This paper uses violations of put‐call parity to provide simple lower and upper bounds for measuring the size of asset price bubbles. Assuming only no‐arbitrage, this bubble detection approach avoids restrictive parametric model assumptions. We show that put‐call disparity provides a bubble's lower bound, and the lowest price of an out‐of‐the ...

When in Doubt, Tax More Progressively? Uncertainty and Progressive Income Taxation

International Economic Review, EarlyView.
ABSTRACT We study the optimal income tax problem under parameter uncertainty about household preferences and wage dynamics. We derive conditions characterizing how such uncertainty affects optimal tax policy. To quantify the effect, we estimate a life‐cycle model using US data and a Bayesian approach.
