House prices,collateral constraint,and the asymmetric effect on consumption

This paper investigates the asymmetric effect of house prices on various categories of consumption under constrained and unconstrained regimes. We first present a simple theoretical model based on Iacoviello (2004) and Luengo-Prado (2006), explicitly considering the dual role of housing and linking credit constraints to the behavior of consumption in a pair of aggregate Euler equations. We then estimate a threshold regression model and find that LC-PIH holds only under the unconstrained regime. More importantly, durable consumption exhibit a very strong asymmetric effect in response to changes in house prices, while other categories of consumption do not exhibit this asymmetry.

Critical creativity criteria for students in higher education: taking the interrelationship effect among dimensions into account

It is known that the overall competitive advantages enjoyed by the Taiwanese higher education system have been decreasing in recent years relative to the educational systems of other countries. In light of aiming to become a kingdom of innovation, how to regain its competitive advantages over the very short term has become a critical issue requiring immediate attention. Based on previous research indicating that improving innovation is among the primary ways of enhancing an education system’s competitive advantages, that creativity is the foundation of innovation, that organizations that truly understand human creativity and are committed to nurturing it and living with the consequences of doing so are those that are most likely to succeed, and that students are a major group to be regarded as the backbone of a nation’s future development, the aim of this study is to explore critical criteria for creativity, which could significantly improve the creativity of college students. Although related studies can be found today, these studies seem to ignore the different effects of different dimensions of creativity evaluation, leading to results that are irrational and not completely suitable for real practice. In this regard, a perception of interrelationships among these dimensions is thus taken into account while calculating weights of evaluation creativity dimensions and criteria. In accordance with the result, the top six explored critical creativity criteria are shown to help enhance today’s college students’ creativity.

Implementing market segmentation using full-refund and no-refund customer returns policies in a dual-channel supply chain structure

Products returned by customers are common in the retail industry and result in costs to both the supplier and the retailer. In practice, retailers implement returns policies that may give customers a full, partial, or no refund for returned products. In this paper, we examine how a firm that faces customer returns can enhance profit by using different customer returns policies, full-refund and no-returns, as a device to segment its market into a dual-channel structure. We also show the impact of customer returns on the firm's pricing and ordering decisions, as well as on the firm's profit in such a dual-channel structure.
