Fiscal Competition in Space and Time [PDF]

open access: yes
This paper analyzes fiscal competition among numerous spatially- separated jurisdictions in an explicitly dynamic framework. The degree of factor mobility between jurisdictions is imperfect because it is costly and time-consuming to adjust factor stocks.

Formation of Stable Amorphous Calcium Phosphate and Collagen Assemblies by a Versatile Spray‐Drying Approach

open access: yesAdvanced Functional Materials, EarlyView.
Amorphous calcium phosphate (ACP) microparticles with long‐term and thermal stability are prepared with or without collagen using a scalable one‐pot spray‐drying process. Under simulated physiological conditions, they crystallize into biomimetic bone mineral and, when combined with collagen, form extrudable, fibrillar bone‐like 3D constructs.

Office Space Supply Restrictions in Britain: The Political Economy of Market Revenge [PDF]

open access: yes
Office space in Britain is the most expensive in the world and regulatory constraints are the obvious explanation. We estimate the ‘regulatory tax’ for 14 British office locations from 1961 to 2005.

Slight Truncation Changes in Iron Oxide Nanocubes Strongly Affect Their Magnetic Properties

open access: yesAdvanced Functional Materials, EarlyView.
Subtle variations in nanoparticle morphology can lead to significant changes in functional properties. An automated shape‐fitting method captures minor differences in corner truncation between iron oxide nanocubes of similar sizes synthesized under identical conditions, revealing pronounced disparities in their magnetic and hyperthermia behavior ...

Managing subnational credit and default risks [PDF]

open access: yes
As a result of worldwide decentralization, subnational debt is rising. Subnational debt crises in major developing countries in the 1990s have led to strengthened regulatory frameworks for subnational borrowing and insolvency.

Control of Polarization and Polar Helicity in BiFeO3 by Epitaxial Strain and Interfacial Chemistry

open access: yesAdvanced Functional Materials, EarlyView.
In BiFeO3 thin films, the interplay of interfacial chemistry, electrostatics, and epitaxial strain is engineered to stabilize homohelicity in polarization textures at the domain scale. The synergistic use of a Bi2O2‐terminated Aurivillius buffer layer and a highly anisotropic compressive epitaxial strain offers new routes to control the polar‐texture ...

A NEW APPROACH OF THE BUDGET DEFICIT: AN EMPIRICAL ANALYSIS [PDF]

open access: yes
Economic policies and, particularly, fiscal policies are not designed and implemented in an “empty space”: the structural characteristics of the economic systems, the institutional architecture of societies, the cultural paradigm and the power relations ...

Tuning the Selectivity of the CO2 Reduction Reaction by Means of Synergistic Interactions in the Cu, Ag, Ce System

open access: yesAdvanced Functional Materials, EarlyView.
Multi‐metal Cu─Ce─Ag nanoparticles harness synergistic interactions to drive efficient electrochemical CO2 reduction reaction toward C2+ products at high current densities. Ag enhances CO production, Ce modulates Cu oxidation states, and together they boost *CO coverage and local pH to enhance C─C coupling, enabling record C2+ yields with suppressed ...
