TFP, News, and "Sentiments:" the International Transmission of Business Cycles
Journal of the European Economic Association, 2015 We propose a novel identification scheme for a nontechnology business cycle shock, which we label “sentiment”. This is a shock orthogonal to identified surprise and news TFP shocks that maximize the short-run forecast error variance of an expectational

Real business cycles are recurrent fluctuations in an economy's incomes, products, and factor inputs - especially labor - that are due to nonmonetary sources.

Advanced Science, EarlyView.The graphical abstract illustrates the photocatalytic mechanism of Sn‐doped ZnGa2O4 with in situ loaded SnO2 (SZGO), highlighting directional electron migration and selective adsorption/activation. ZnGa2O4 domains facilitate H2O activation to generate ·OH radicals, while SnO2 domains enriched with electrons promote O2 activation to form ·O2− and 1O2 ...

Classical Business Cycles in America: Are National Business Cycles Synchronised? [PDF]
This paper provides further evidence on the synchronization between business cycle regimes in seven American countries by using a classical business cycles approach. Despite recent increasing international economic transactions within this continent, our

Advanced Science, EarlyView.Based on rational feature selection, an integrated‐feature dataset is constructed encompassing macro‐ and micro‐feature parameters. Screening and optimization across ten algorithmic models enhanced predictive accuracy and robustness for power conversion efficiency (PCE), yielding an R2 of 0.9464 and RMSE of 1.27%.

Advanced Science, EarlyView.Herein, a new catalyst, protonated layered perovskite HPrNb2O7, is presented, which exhibits exceptional photocatalytic activity for solar‐driven ammonia decomposition. Its unique structure facilitates the generation of active sites while extending charge carrier lifetime with input thermal energy. Abstract Photocatalytic ammonia decomposition offers a
