Crises and collective socio-economic phenomena: simple models and challenges

, 2012
Financial and economic history is strewn with bubbles and crashes, booms and busts, crises and upheavals of all sorts. Understanding the origin of these events is arguably one of the most important problems in economic theory.

Chemical Doping Engineering of Polarization and Topological Textures in van der Waals Ferroelectric CuInP2S6

Advanced Science, EarlyView.
Our work reports that Li⁺ doping in CuInP2S₆ induces coexistence of high‐ and low‐polarization states, which fosters a rich spectrum of topological polar textures, such as bubbles and labyrinth domains. An unconventional flexoelectric effect is also discovered, where strain gradients can mechanically manipulate these polarization states and their ...

Ideological Polarization, Sticky Information, and Policy Reforms [PDF]

We develop a dynamic two-party political economy framework, in which parties seek to maximize vote share and face the trade-off between catering to their respective core constituencies on the one hand and ‘middle of the road’ voters with no partisan ...

Robust Smart Superhydrophobic Cilia

Advanced Science, EarlyView.
To date, ciliated surfaces cannot withstand mechanical damage because cilia/wires are inherently fragile. By aligning magneto‐responsive, flexible, superhydrophobic microwires on the sidewall of vertical frames, the frames act as armors to protect microwires from mechanical damage; when needed, the microwires re‐align uprightly under a magnet field to ...

The Fox News Effect: Media Bias and Voting [PDF]

Does media bias affect voting? We address this question by looking at the entry of Fox News in cable markets and its impact on voting. Between October 1996 and November 2000, the conservative Fox News Channel was introduced in the cable programming of 20

Polymorphic Superparaelectric Engineering Boosting Energy Storage Capacity in BaTiO3‐Based Ceramics

Advanced Science, EarlyView.
Herein, Ca2+ incorporation promotes the coexistence of CaTiO3‐/BaTiO3‐derived paraferroelectric states, stabilizing cubic‐orthorhombic‐tetragonal polymorphic superparaelectric phases. This minimizes polarization energy barriers, facilitating full polarization saturation without compromising efficiency.

Reversible and Controllable Transition Between Filamentary and Interfacial Resistive Switching in HfO2‐Based Memristors

Advanced Electronic Materials, EarlyView.
5 nm HfO2 memristors exhibit a fully reversible, voltage‐controlled transition between filamentary and interfacial switching within the same device. At high voltages, a filament forms and dominates the conduction, whereas at lower voltages the device reversibly returns to interfacial mode without defect accumulation, implying a new reversible ...

Demographic Change, Intergenerational Altruism, and Fiscal Policy : A Political Economy Approach [PDF]

Our study employs an OLG model under which political strengths of different generations (the working and retirees with and without children) determine the distribution of the fiscal burden between the generations, including the future generation.
