We develop a quantitative business cycle model with search complementarities in the inter-firm matching process that entails a multiplicity of equilibria. An active static equilibrium with strong joint venture formation, large output, and low unemployment can coexist with a passive static...

Defensive hiring of researchers by incumbent firms with monopsony power reduces creative destruction. This mechanism helps explain the simultaneous rise in R&D spending and decline in TFP growth in the US economy over recent decades. We develop a simple model highlighting the critical role of...

Education is a fundamental factor to enhance a country’s comprehensive national strength and international competitiveness. Recently, several governments have been attracting investments in educational sectors in contemplation of meliorating a country’s overall strength. This study...

In this study, a metal–organic framework (MOF)-supported Co-doped hollow carbon nitride (ZCCN) catalyst was constructed by etching zeolitic imidazolate framework-67 (ZIF-67). Excellent visible light capture and electron transfer performance of the catalyst were revealed, and 99% tetracycline...

Despite the growing interest, limited studies have been conducted on LID spatial allocation optimization (SAO) at neighborhood scale, and no study has applied modifications to the optimization algorithm to improve its performance. In this study, such a new LID SAO system was proposed, which...

A remnant fertilizer monitoring system utilizing three-dimensional (3D) reconstruction is proposed to detect the amount of remaining fertilizer in the applicator’s tank. Bench tests are carried out to compare the performance of four algorithms to estimate the remnant fertilizer amount:...

In order to investigate the influence of minor Ru on electrochemical behavior and structural characteristics of passive film on the surface of Ti-6Al-4V alloy in various oil & gas exploration conditions, electrochemical techniques, XPS, SEM and corrosion simulation tests were carried out, and...
