A choice-based multi-product diffusion model incorporating replacement demand

This study proposes an integrated forecasting model that incorporates both first purchase diffusion and replacement component of sales in predicting multi-product diffusion patterns. The model consists of a two-stage procedure that customers undertake during purchase occasions according to a diffusion process or replacement process, and at each occasion, they make purchase incidence decisions and product choices according to a choice model. By incorporating various exogenous factors in the choice model, the model can identify the impact of each factor on customers' purchase incidence decisions and choice decisions among various product sub-categories. This approach enables us to understand the overall process of customers' purchasing behavior and to separate total sales amount into sales to three consumer segments: first-time buyers, customers who repurchase the same product category and customers who change their previous product category. We applied the proposed model in the forecasting multi-product framework; forecasting sub-category level automobile sales and brand level mobile terminal sales in the South Korean market. The results of the empirical studies showed that incorporating the replacement components into the multi-product diffusion framework is useful not only in understanding the demand interaction among automobile categories and among mobile handset brands, but also in producing more accurate long-term sales forecasts compared to previous multi-product diffusion models.     

An empirical analysis of the determinants of technology roadmap utilization

For many years now, firms have managed their research and development (R&D) by applying various approaches drawn from the discipline of technology roadmapping (TRM). The underlying rationale of these roadmapping approaches is to align firms' product and technology developments with their business goals. By visually representing firms' technology strategy, roadmaps support intra‐firm communication and facilitate the coordination of strategic decisions and activities within the technology management domain. Most previously published research on TRMs has focused on the design and implementation of roadmapping processes; that is, relatively few empirical or quantitative studies describe the use and evaluation of roadmapping techniques. This paper seeks to address this gap by conducting a survey of 186 different R&D units within stock market‐listed companies in Korea that have implemented TRM. The paper attempts to identify the antecedent factors behind firms' successful use of roadmaps, further identifying correlations between these antecedent factors through an analysis of the R&D units. It also empirically highlights these antecedent factors by empirically analyzing and verifying correlations between roadmap utilization and R&D performance.     

Ethical purchasing perceptions and practices of Oklahoma restaurant managers

This study examined ethical business perceptions and practices in purchasing dealings between junior and senior managers in the U.S. restaurants. This study investigated the managerial style in the context of business ethics relative to employees’ loyalty, ethical working behavior, attitude, and decision‐making process of restaurant's food purchasing personnel. Additionally, organizational business ethics training for employees is a crucial component to enhance adherence to an ethical code of conduct. The findings revealed that the managers’ ethical purchasing perceptions and practices of their employees’ behaviors were not different in terms of gender, age, and years of experiences as a manager. Corporate ethical standards and managerial ethical practices can guide managers and employees as to how to behave when confronted with a dilemma with regard to ethics and personal interest. Consequently, the prime principle of management or purchasing personnel in terms of ethical dealings has tremendous impact on a firm's operational performance and employees’ morale.     

Augmented Reality Smart Glasses (ARSG) visitor adoption in cultural tourism

ABSTRACT

A number of organizations in cultural tourism have started to explore the use of augmented reality (AR) to enhance visitor experience. While many studies have been conducted to identify adoption criteria of mobile AR applications, research exploring the adoption of augmented reality smart glasses (ARSG) is still limited. This paper contributes to the technology adoption literature by investigating attributes of visitor adoption of ARSG in cultural tourism. Twenty-eight interviews were conducted with visitors to a UK art gallery, where they experienced an ARSG application. Findings inform an ARSG adoption framework that integrates societal impact, perceived benefits, perceived attributes of innovation, and visitor resistance as the main themes of ARSG adoption in cultural tourism.     

Dollarization,Seigniorage, and Prices: The Case of North Korea

This study employs a general equilibrium monetary search model to examine the effects of the recent dollarization in North Korea on seigniorage and prices. Maximum seigniorage is generated at a high rate of money growth when dollarization is mild. However, under a high degree of dollarization seigniorage declines sharply when the money growth rate is high. Accordingly, seigniorage can be increased by de-dollarizing the economy through lowering the money growth rate. This finding implies that the post-2013 price stabilization may be a result of the restriction on printing of money with the aim of increasing seigniorage. This finding also recognizes that the North Korean authorities have little room for maneuver on monetary policy under the conditions of widespread dollarization.     

Monetary policy and efficiency in over‐the‐counter financial trade

We develop a monetary model that incorporates over‐the‐counter (OTC) asset trade. After agents have made their money holding decisions, they receive an idiosyncratic shock that affects their valuation for consumption and, hence, for the unique liquid asset, namely money. Subsequently, agents can choose whether they want to enter the OTC market in order to sell assets and thus boost their liquidity or to buy assets and thus provide liquidity to other agents. In our model, inflation affects not only the money holding decisions of agents, as is standard in monetary theory, but also the entry decision of these agents in the financial market. We use our framework to study the effect of inflation on welfare, asset prices and OTC trade volume. In contrast to most monetary models, which predict a negative relationship between inflation and welfare, we find that inflation can be welfare improving within a certain range, because it mitigates a search externality that agents impose on one another when they make their OTC market entry decision. Also, an increase in the holding cost of money will lead to a decrease in asset prices, a regularity that is well documented in the data and often considered anomalous.     

Patent Licensing in the Presence of Trade Barriers

We develop a two‐country duopoly model to explore the optimal licensing contract for an outsider licensor in terms of fixed‐fee and royalty licensing by taking into account trade barriers when firms produce a homogeneous product and engage in Bertrand competition in each market. The present paper focuses on the interaction between licensing and trade barriers in two international markets. We show that both royalty and non‐exclusive fixed‐fee licensing can be optimal. Furthermore, exclusive fixed‐fee licensing can be optimal, which is a result that is not discussed in the existing literature.     

Political Authority and Bureaucratic Resilience

Abstract

Consumerism and choice have become prominent ideas in the design and delivery of public services. Often perceived as a way to improve the quality and value of public services, potential downsides and areas of concern that relate to a consumerist approach are frequently ignored. This review essay takes a critical stance on the application of a consumerist discourse to public service provision and management by exploring four key areas of concern: definitional problems, questions about the concept's transferability from a private to a public sector setting, the problematic nature of ‘choice’, and difficulties associated with implementing consumerist ideas within public service contexts..     

Relationships among leader–member exchange,person–organization fit and work attitudes in Japanese and Korean organizations: testing a cross-cultural moderating effect

This study examines a possible national culture difference in the moderating effect of leader–member exchange (LMX) on the relationship between person–organization (P–O) fit and work attitudes, including job satisfaction and organizational commitment, in Japan and Korea. Specifically, we use trait activation theory as a lens to explain the complementarities between P–O fit and LMX that may exert an influence on employees' work attitudes. We hypothesize that from the cross-cultural management perspective, such complementary effects would work in Japan where organizations encourage more decentralization and empowerment than those in Korea, which may enable supervisors in Japanese organizations to provide unambiguous reward expectancies for their immediate subordinates. Using samples of 138 Japanese and 144 Korean employees working for privately owned firms in Japan and Korea, we demonstrate that a significant three-way interaction of employees' P–O fit, LMX and a national culture difference (i.e. nationality) influences their work attitudes. Specifically, LMX moderated the positive relationships between P–O fit and both job satisfaction and organizational commitment for Japanese employees, tending to weaken them. For Korean employees, however, no such interactions were observed. The findings are used to discuss the applicability and generalizability of trait activation theory in East Asian cultures. In addition, suggestions are made regarding the discussion of HRM practices from a cross-vergence perspective. Limitations and directions for future research are also discussed.     

Debates over labor reforms in Post‐Mao China (1978–1995)

Why was it that, from 1978 to 1995, the central government of the People's Republic of China did not successfully implement labor reforms? The paper explains the outcomes of China's labor reforms in a statist perspective. The hypothesis is that, despite labor reforms of 1978 to 1995, due to the limited autonomy of the central government, China has not successfully formulated and implemented employment reforms. Ideological coherence and organizational unity among the central party‐state elites are the preconditions for the autonomy, or more accurately, relative autonomy of central governments. Conflicts and debates among various factions destroy the cohesion of the central government, weakening the relative autonomy of the central government to act as a coherent entity.
