Corporate Tax System Complexity and Investment Sensitivity to Tax Policy Changes
Journal of Accounting Research, EarlyView.ABSTRACT Effective policymakers must balance the demands of formulating a corporate tax system that raises revenue and spurs economic activity (e.g., investment) while promoting a “level playing field” across firms. Balancing these tradeoffs has likely caused tax systems to become more complex over time, increasing firms’ difficulty in understanding ...

Preemptive Entry and Technology Diffusion: The Market for Drive‐In Theaters
The RAND Journal of Economics, EarlyView.ABSTRACT This article studies entry preemption in new industries. We first test a key prediction of dynamic entry games: Entry preemption is most relevant in intermediate‐sized markets, where firms face highest uncertainty about future entry. Using US drive‐in theater market (1945–1957) data, we find robust evidence for this non‐monotonic relationship ...

Methods in Ecology and Evolution, EarlyView.Abstract Ecologists are adapting structural causal modelling for spatial, phylogenetic and time‐series analysis. However, ecological extensions of path analysis and structural equation models (SEM) typically assume that interactions among variables are stationary, linear and additive, while ecological and evolutionary dynamics are often nonstationary ...

SDFs from Unoriented Point Clouds using Neural Variational Heat Distances
Computer Graphics Forum, EarlyView.We propose a novel variational approach for computing neural Signed Distance Fields (SDF) from unoriented point clouds. We first compute a small time step of heat flow (middle) and then use its gradient directions to solve for a neural SDF (right). Abstract We propose a novel variational approach for computing neural Signed Distance Fields (SDF) from ...
