Impact of Geography on Institutions in Agricultural and Nomadic Societies

International Studies of Economics, EarlyView.
ABSTRACT How geography affects the choice of institutions is studied in a theoretical model. In this model, nations are located around a circle. Rulers compete through choosing tax rates, the level of military spending, and the degree of formality of institutions. Geographic condition is captured by population density.

A Local Projections Approach to Difference‐in‐Differences

Journal of Applied Econometrics, EarlyView.
ABSTRACT We propose a local projections (LPs)‐based difference‐in‐differences (DiD) approach that subsumes many of the recent solutions proposed in the literature to address possible biases arising from negative weighting. We combine LPs with a flexible “clean control” condition to define appropriate sets of treated and control units.

The PCDID Approach to Treatment Effects Estimation: A Further Investigation

Journal of Applied Econometrics, EarlyView.
ABSTRACT In the present paper, we study the so‐called “PCDID” approach to treatment effects estimation in panels with interactive effects where the factors represent trends whose effect need not be parallel across the cross‐sectional units. Our interest in this step‐wise approach originates with the observation that the interactive effects are ignored ...

Last‐minute coordination: Adapting to demand to support last‐mile operations

Journal of Operations Management, Volume 71, Issue 2, Page 176-194, March 2025.
Abstract In the highly competitive e‐commerce industry, customer‐facing warehouses are crucial as the “order penetration points” for e‐commerce last‐mile operations. This research examines how warehouses use last‐minute coordination, an unstructured mechanism, to ensure sufficient inventory at the order penetration points. Previous research has focused

Identity‐Enabled CDMA LiDAR for Massively Parallel Ranging with a Single‐Element Receiver

Laser &Photonics Reviews, EarlyView.
A novel LiDAR system integrates CDMA modulation with a single‐element detector to achieve massive channel parallel 3D imaging. By using a user identification code and a correlation‐based feedback loop, it overcomes signal collisions and the near‐far problem.

Customized Scattering‐Robust 3D Speckle Correlation for Improved Resolution and Imaging Depth in Scattering Tissue

Laser &Photonics Reviews, EarlyView.
A scattering‐robust 3D speckle customization method is proposed to enhance both resolution and imaging depth in scattering tissue. Applied to light‐field microscopy (LFM), it improves 3D resolution by over twofold under strong optical scattering. In wide‐field fluorescence imaging, it enables a substantial improvement in imaging depth, allowing imaging
