Assortment selection is one of the most important decisions faced by retailers. Most existing papers in the literature assume that customers select at most one item out of the offered assortment. While this is valid in some cases, it contradicts practical observations in many shopping...

Strategic management has been widely recognised as very potent tools for enhancing organizational performance, productivity and competitive advantage of organizations’. Therefore, this study explores the use of one of the multivariate analysis (Principal Component Analysis) to determine...

Agents are generally uncertain about multiple, and possibly time-varying, structural parameters that drive consumption and financial payoffs but learn through noisy correlated signals, such as aggregate or macroeconomic news. We find that dynamic learning of multivariate time-varying parameters...

The multivariate test of means, using the Hotelling’s T2 distribution, has vast applications in many real-life situations; education inclusive. Prominent amongst them is the test of means between two groups; say treatment and control groups in tests scores given an intervention. The objective...

Multivariate analysis can help to focus on economic phenomena, including trend and cyclical movements. To allow for potential correlation with seasonality, the present paper studies a three component multivariate unobserved component model, focusing on the case of quarterly data and showing that...

The importance for the accurate forecast of carbon emissions affected by many factors is gradually emerging. Carbon emissions usually lag behind the related factors, which cannot be dynamically reflected in the existing grey forecasting models. Therefore, investigating the dynamic lag...

Agents who pursue optimal portfolio choice by optimizing a univariate objective (e.g., an expected utility) obtain optimal payoffs that are increasing with each other (comonotonic). This situation may lead to an undesirable level of systemic risk for society. A regulator may therefore aim to...

The existence of time-varying risk premia in deviations from uncovered interest parity (UIP) is investigated based on a conditional capital asset pricing model (CAPM) using data from four Asia-Pacific foreign exchange markets. A parsimonious multivariate generalized autoregressive conditional...
