This paper studies the signalling effect of the consumption-wealth ratio (cay) on German stock returns via vector error correction models (VECMs). The effect of cay on U.S. stock returns has been recently confirmed by Lettau and Ludvigson with a two-stage method. In this paper, performance of...

As energy heating is one of the main production costs, many efforts have been made to reduce the energy consumption of agricultural greenhouses. Herein, a novel control method of greenhouse heating using computational fluid dynamics (CFD) and energy prediction model (EPM) is proposed for energy...

Access to health care in the United States remains greatly disproportionate across socioeconomic groups. It is not known, however, whether the disparities between the socioeconomic categories are increasing or decreasing. This analysis used a well-established non-parametric technique, employing...

Purpose The purpose of this study is to explore mitigation measures for cash flow interruption during the epidemic and provide decision support to ensure the regular operation and robustness of the supply chain (SC). Design/methodology/approach Considering the scenarios of production capacity...

Purpose The sensorless external force estimation of robot manipulator can be helpful for reducing the cost and complexity of the robot system. However, the complex friction phenomenon of the robot joint and uncertainty of robot model and signal noise significantly decrease the estimation...

Purpose The purpose of this study is to explore the information needs and behaviors of Chinese first-time mothers from the perspective of information journey theory. Design/methodology/approach This study uses the popular coding language Python to write a program to extract 366 posts published...

Two of the most discussed issues triggered by the so called Feldstein-Horioka puzzle in international macroeconomics are: What does the saving-investment (SI) relation really measure and how should the SI relation be measured? The first contribution of this study is to develop a new variant of...
