This study aims to propose risk factor analysis and to estimate how risk factors impact the average production efficiency of Thai sawn rubberwood timber exports to China as this impact could represent an aspect of the market. Data from the Risk in Value Chain concept and in-depth interviews with Thai sawn rubberwood timber exporters were used to identify the variables.

The primary purpose of this study is to compare Capital Asset Pricing Model with Arbitration Pricing Theory by considering the supply chain strategy. Another objective of this study is to determine the effect of Capital Asset Pricing Model (CAPM) and Arbitration Pricing Theory (APT) on excess returns and to determine the best asset pricing model in terms of ability to explain the estimation of excess return. This study examines the effect of variables in asset pricing models and compares the ability of asset pricing models in explaining excess return.

Polygenic risk scores (PRSs) are a summarization of an individual’s genetic risk for a disease or trait. These scores are being generated in research and commercial settings to study how they may be used to guide healthcare decisions. PRSs should be updated as genetic knowledgebases improve; however, no guidelines exist for their generation or updating.

In a study, if a relationship does not take into account the mediating mechanism, then it fails to get complete understanding of the relationship. In addition, failing to consider the effect of a mediator may not have clear explanation of the relationship outcome. Contrarily, a model which considers the mediating mechanism is likely to estimate accurate relationship among variables under study.

Do countries consume more electricity as they become richer? This study uses an instrumental variables approach to investigate the connection between electricity consumption and economic growth. With panel data of 32 countries spanning the period of 1996-2014, two potential instruments, which are an oil price shock as the main focus and past saving rates, are used for estimation.
