Profit inefficiency of Japanese securities firm [PDF]

We develop a new indicator of profit inefficiency, which is based on decision-makers choosing the amount to spend on each input and the amount to earn on each output, rather than choosing physical quantities of inputs and outputs.

Self‐Assembled Monolayers in p–i–n Perovskite Solar Cells: Molecular Design, Interfacial Engineering, and Machine Learning–Accelerated Material Discovery

Advanced Materials, EarlyView.
This review highlights the role of self‐assembled monolayers (SAMs) in perovskite solar cells, covering molecular engineering, multifunctional interface regulation, machine learning (ML) accelerated discovery, advanced device architectures, and pathways toward scalable fabrication and commercialization for high‐efficiency and stable single‐junction and

Loan Volume and Interest Rate Determination in a Banking Market with Imperfect Competition [PDF]

Financial Markets, Institutions and Risks
In imperfectly competitive banking markets, the determination of loan volume and interest rates matters because even modest differences in banks’ loan-origination efficiency can alter credit availability, borrowing costs, and the transmission of ...

Endogenous Business Cycles and Dynamic Inefficiency [PDF]

This paper explores how the occurrence of local indeterminacy and endogenous business cycles relates to dynamic inefficiency, as defined by Malinvaud (1953), Phelps (1965) and Cass (1972).

Optimal Control Drives Ultrafast and Energy‐Efficient Magnetization Switching in Van der Waals Magnets

Advanced Materials, EarlyView.
ABSTRACT The accelerating expansion of data‐centric technologies is sharply increasing the energy burden of information storage, placing unprecedented pressure on the efficiency of magnetic switching. Conventional field‐driven reversal, once the foundation of magnetic memory, has become impractical in modern architectures due to its high energy cost ...

Equilibrium Wage Distributions [PDF]

This paper analyzes equilibrium in labor markets with costly search. Even in steady state equilibrium, identical labor may receive different wages; this may be the case even when the only source of imperfect information is the inequality of wages which ...

When Poor Exciton Dissociation Limits Photocurrents in Organic Solar Cells: Why Low Offset Non‐Fullerene Acceptor Blends Can't Be Efficient

Advanced Materials, EarlyView.
The energetic offset between the donor and the acceptor components in organic photoactive layers is central to the tradeoff between photovoltage and photocurrent losses. This Perspective covers the most important issues surrounding this topic in non‐fullerene acceptor blends, from the difficulty of accurately determining state energies and driving ...

Public investment in infrastructure, capital inefficiency and economic performance in Morocco: insights from a dynamic CGE model

Cogent Economics & Finance
Since the early 2000s, Morocco has undertaken extensive socio-economic reforms and intensified its public investment efforts to modernize the economy and expand infrastructure. However, despite having one of the highest investment rates in the world, the

Democratic Reforms, Foreign Aid and Production Inefficiency [PDF]

We construct an endogenous growth model and we employ empirical analysis to investigate the link between foreign aid and production efficiency in the presence of different political orientations of the recipient country.

A Geometrically Transient Platform for Bioelectronic Implants

Advanced Materials, EarlyView.
Minimally invasive bioelectronic implants often compromise performance for smaller sizes. To resolve this optimization dilemma, a wireless bioelectronic implant with a transient geometry is introduced (MiFi). The origami‐inspired device miniaturizes up to sixfold for syringe insertion and autonomously unfolds post‐implantation.
