The effects of exchange rate pass-through and cost channel on price level: The case of fragile five countries

ABSTRACT

In this study, we investigated whether the exchange rate and the interest rate had an effect on the inflation rate in the fragile five countries between the years of 1996Q4 and 2015Q4. In this context, a model was created to estimate the effect of interest rate and exchange rate on the inflation rate. The methods used in the study take into account cross-section dependence and heterogeneity. As a result of the analysis, it was determined that there was an exchange-rate and interest-rate pass-through effect in the fragile five countries. Moreover, it was found out that the cost channel and price puzzle were effective in Indonesia and South Africa but were not effective in Turkey, Brasil and India.     

The heterogeneity of beauty premium in China: Evidence from CFPS

Using a nationwide representative sample of the Chinese population, we examine the effect of physical appearance on the hourly wage. Our theoretical framework that connects physical appearance and the hourly wage has two predictions. First, the beauty premium is larger for high-skilled workers than for low-skilled workers. Second, this statistical-based discrimination arises from the hiring manager’s belief that beauty contributes to productivity through non-cognitive skills. Empirical results confirm both predictions. Good-looking individuals earn roughly 5.4% more than the rest, and bad-looking individuals earn roughly 3.3% less than the rest. Moreover, quantile estimates show that the effect of physical appearance at the 0.75 quantile is more than twice as the one at the 0.25 quantile. Finally, social skills, communication skills, and self-confidence are three transmission channels through which physical appearance can positively affect one’s hourly wage in our sample. Our findings imply that the beauty premium is widespread in the labor market and relevant anti-discrimination regulations are needed.     

On the role of Islamic and conventional banks in the monetary policy transmission in Malaysia: Do size and liquidity matter?

This paper empirically investigates the impact of monetary policy on the credit supply of Islamic versus conventional banks of Malaysia using an unbalanced panel dataset over the period 2005-2016. While estimating the effects of three alternative measures of monetary policy on banks' credit supply, we include several bank-specific and macroeconomic variables in the specification as control variables. We provide strong evidence on the existence of the credit channel of monetary policy transmission mechanism in Malaysia. Yet, we show that Islamic banks respond considerably less to changes in monetary policy instruments as compared to their conventional counterparts. We also find that the monetary policy measures affect small-sized banks and less-liquid banks more as compared to large-sized and more-liquid banks. Our findings suggest that for an effective monetary policy, there is a vital need to consider the nature of Islamic banking while devising any monetary policy instruments to manage credit supply in the economy.

Bridge,Focus, Attack,or Stimulate: Retail Category Management Strategies with a Store Brand

We investigate a monopolist retailer's category management strategy where the main strategic decisions are how to horizontally position a store brand relative to the incumbent national brands and how to price the store and national brands for retail category profit maximization. We analyze a market composed of two consumer segments with differing tastes and heterogeneity with respect to willingness to pay and a product category consisting of two competing national brands and one store brand. We find that contrary to the existing literature, it is not always optimal for a retailer to position its store brand against the leading national brand; instead there are many situations where it is best to position the store brand close to the weaker national brand or to position it in the “middle” so it appeals to both national brands' target segments. In the process we identify four distinct category management strategies that a retailer can use with a store brand. In three of these the optimal store brand price is the brand's monopoly price, while in the remaining one strategy the price is lower. We also suggest an easy to implement means for a retailer to determine which strategy is best to use, depending on the particular competitive environment present before the introduction of the store brand and the relative quality of the store brand. We find that the store brand entry is most beneficial to the retailer when the national brands are moderately differentiated. Finally we show that introducing a store brand not only allows the retailer to garner a higher share of the channel profits through higher retail margins, but also often provides the retailer the benefit of increases in national brand unit sales as well as incremental sales from the store brand.

货币政策的国际溢出效应与国际协调研究进展

随着世界各国经济活动关联程度的不断增强,一国货币政策变动对其他国家经济社会发展的影响越来越显著,国家间的货币政策协调也愈加重要。在此背景下,有关货币政策国际溢出效应的研究日益丰富,货币政策的国际协调也逐渐受到关注。本文对货币政策国际溢出效应及国际协调领域的现有文献进行回顾和展望。从货币政策国际溢出效应研究的发展历程来看,1990年以前相关研究主要基于开放条件下的宏观经济模型及博弈论等进行理论探讨,1990年至2000年多数研究开始借助动态随机一般均衡模型和经济计量模型探究货币政策国际溢出效应的传导机制和渠道,2000年以后越来越多的研究将理论应用于对现实经济问题的解释,其中以探讨中心国家货币政策的国际溢出效应为主。从货币政策国际溢出效应的研究方法来看,相关研究大多通过控制货币政策的内生变化来获取货币政策的外生冲击,主流研究方法也逐渐从基于MFD模型的纯理论分析转向基于VAR系列模型的实证分析和具有一致性框架的DSGE模型分析。从货币政策国际溢出效应的传导渠道来看,早期文献大多认为汇率和贸易是主要渠道,随着全球经济金融一体化的推进,金融渠道的作用日益凸显,且比汇率渠道和贸易渠道传导更加迅速、后果更为严重,并逐渐成为近些年研究的重点。由于货币政策的国际协调在实践中存在一定难度以及经济下行压力较大下的货币政策调整空间较小,目前关于货币政策国际协调的研究相对较少,而且相关研究的观点并不统一。大部分学者认为随着世界经济联动趋势的不断增强,货币政策国际协调是必然趋势并有利于各国经济发展,而部分学者认为政策协调需要花费大量的时间和政治成本,货币政策的国际协调应慎重。现有研究已经取得丰硕成果,但仍需进一步深化和拓展：一是大多数文献仅考察中心国家货币政策对外围国家（新兴经济体）的单向溢出效应,有必要进一步考察货币政策的双向国际溢出效应;二是关于金融渠道的研究还不够完善,尤其是对货币政策不确定性冲击、全球金融风险传递等的研究较少,相关研究需要深化;三是关于货币政策国际协调的研究较少且观点不统一,尤其是对政策协调的有效路径缺乏系统研究,相关研究有待加强。中国学者应加强该领域的研究,尤其要在中国货币政策的国际溢出效应及其传导渠道、应对国外货币政策溢出效应的有效政策工具、促进货币政策的国际协调等方面取得突破。

Brand Loyalty Versus Store Loyalty: Consumers’ Role in Determining Dependence Structure of Supplier–Retailer Dyads

Purpose: This article aims to integrate consumers into a channel dependence framework and explores the influence of consumers’ brand loyalty and store loyalty on the dependence structure within the supplier–retailer relationship. It also examines effects of the dependence structure on perceived conflict.

Methodology/approach: The authors test the proposed triadic relationship model among department store, supplier, and consumer by collecting matched data from both retailers and consumers in a Chinese retailing channel of sports and leisure apparel. Polynomial regression in conjunction with a response surface analysis (RSA) approach is used to test the hypotheses.

Findings: The results indicate that consumers’ brand loyalty positively affects retailer’s dependence on supplier, while consumers’ store loyalty positively affects supplier’s dependence on retailer. In addition, the retailer’s dependence is higher when consumers’ brand loyalty is higher than store loyalty; the supplier’s dependence is higher when consumers’ store loyalty is higher than brand loyalty; and the retailer’s dependence increases with the increase of both consumers’ brand and store loyalty when consumers’ brand and store loyalty are equal. Moreover, supplier’s dependence has a negative linear effect on retailer’s perceived conflict, whereas retailer’s dependence has an inverted U-shape effect on perceived conflict. A retailer would perceive more conflict when the retailer is relatively more dependent on the supplier; but the symmetrical interdependence has no significant effect on retailer perceived conflict.

Research implications: Researchers are encouraged to explore channel behaviors from a network perspective. Consumers, in particular, should be included in research frameworks related to channel dependence and behaviors. Suggestions for further research on the effects of dependence on the conflict are also proposed.

Originality/value/contribution: This study goes beyond the dyadic paradigm by integrating consumers into the framework of the channel dependence structure. It develops and tests a mechanism of consumers’ brand and store loyalty influencing dependence structure within a supplier–retailer dyad. It also enriches the literature of channel conflict by exploring the effects of retailer and supplier unilateral dependence on retailer perceived conflict with RSA methods.

Practical implications: The article provides several insightful implications for managers in understanding and managing interdependence structure in business-to-business marketing, especially in supplier–retailer relationships.
