Estimation of interregional input–output table using hybrid algorithm of the RAS method and real-coded genetic algorithm

In this paper, we propose a method for improving the accuracy of the estimation of interregional input–output tables, by combining the RAS method and the real-coded Genetic Algorithm (GA); these are simple representative methods for the estimation of an interregional input–output table. By comparing the performance evaluation results obtained using the proposed method, the RAS method, and Simulated Annealing, we verified that the combination of the genetic algorithm and the RAS method can enhance the estimation accuracy of an interregional input–output table. In addition, performance is further enhanced by adjusting GA parameters.     

Optimal transit fare and service frequency of a nonlinear origin-destination based fare structure

This paper proposes a new nonlinear distance-based transit fare structure, which is measured by a function of the Euclidean distance between the origin and destination stations, termed as Origin-Destination (OD)-based fare. The novel fare structure encourages passengers to freely choose the most efficient trip plan. An optimization model is formulated based on a three-party game (involving the transport authority, transit company, and passenger) to determine the optimal fare function and frequency. An artificial bee colony algorithm is adopted to solve the model. Finally, a numerical example is provided to verify the proposed method.     

The emergence of home-based accommodations in Iran: A study of self-organization

This paper examines the Iranian home-based accommodation sector using the theory of self-organization. With the aim of identifying the sector's organizing principles, interviews were conducted with the accommodation operators, providing 117 statements which were linked based on their key ideas and/or words. Using UCINET6, a network diagram of five organizing principles were identified: collective identity, balanced legitimacy, local embeddedness, mindful market, and networked finance. While the combination of these organizing principles is interpreted within the Iranian context, broad assumptions can be inferred. It is speculated that a collective aiming to organize itself needs to be considerate of its interactions with members of the collective, the authoritative body, the local community, the market, and capital. Additionally, each separate organizing principle might have relevance for small businesses in various industries. The study contributes to the commercial home and home-based accommodation literature while also providing insights into tourism development in Iran. Furthermore, the method used to identify organizing principles is considered novel and can be used with other collectives.     

Ethical leadership and its impact on service innovative behavior: The role of LMX and job autonomy

This study examined the effect of ethical leadership on service innovative behavior of employees at small and medium sized tourist hotels in Uttarakhand, India. It has forwarded an integrated model that highlights the relationship between ethical leadership and employees' service innovative behavior while interacting through leader-member exchange and job autonomy. Using a sample of 468 customer contact employees and their 117 supervisors, hierarchical regression was conducted to establish the relationship. Findings of the study revealed that ethical leadership promoted service innovative behavior of the hotel employees mediated through leader-member exchanges. Further, it was also found that the level of service innovative behavior was commensurate to the perception of employee job autonomy. Based on the study findings, implications for theory and practice are discussed.     

The savings multiplier

A theory of macroeconomic development based on the novel concept of savings multiplier is developed. Capital accumulation changes relative prices, amplifying incentives to save as the economy grows. The savings multiplier hinges on two mechanisms. First, accumulation raises wages and leads to redistribution from the consuming old to the saving young. Second, higher wages raise the price of old-age care and, in anticipation of this, the young save more. Our theory captures important aspects of China׳s development and suggests new channels through which the one child policy and the dismantling of social benefits have fueled China׳s savings rates.     

Optimal dynamic reinsurance with dependent risks: variance premium principle

In this paper, we consider the optimal proportional reinsurance strategy in a risk model with two dependent classes of insurance business, where the two claim number processes are correlated through a common shock component. Under the criterion of maximizing the expected exponential utility with the variance premium principle, we adopt a nonstandard approach to examining the existence and uniqueness of the optimal reinsurance strategy. Using the technique of stochastic control theory, closed-form expressions for the optimal strategy and the value function are derived for the compound Poisson risk model as well as for the Brownian motion risk model. From the numerical examples, we see that the optimal results for the compound Poisson risk model are very different from those for the diffusion model. The former depends not only on the safety loading, time, and the interest rate, but also on the claim size distributions and the claim number processes, while the latter depends only on the safety loading, time, and the interest rate.     

Aligning corporate transfer intentions and subsidiary HRM practice implementation in multinational corporations

We study HRM practice implementation in subsidiaries of multinational corporations (MNCs) and diverge from extant research by focusing on alignment, which we conceptualize as the degree to which subsidiary implementation of HRM practices corresponds with the subsidiary-specific transfer intentions of corporate headquarters. In explaining alignment we examine different aspects of the headquarters–subsidiary relationship, namely, the extent of formal control, interpersonal relationships and subsidiary strategic HRM capabilities. Based on a sample of 105 subsidiaries from 12 Nordic MNCs, the results highlight the importance of expatriates, trust and the strategic HRM capabilities of the subsidiary HR function. We conduct post hoc analyses to shed further light on (i) the relationship between our independent variables and the two separate components of alignment – corporate intentions and subsidiary implementation, and (ii) two different types of misalignment – excessive and insufficient.     

Wealth effects and agency costs

We analyze how the agent's initial wealth affects the principal's expected profits in the standard principal–agent model with moral hazard.We show that if the principal prefers a poorer agent for all specifications of action sets, probability distributions, and disutility of effort, then the agent's utility of income must exhibit a coefficient of absolute prudence less than three times the coefficient of absolute risk aversion for all levels of income, thus strengthening the sufficiency result of Thiele and Wambach (1999). Also, we prove that there is no condition on the agent's utility of income alone that will make the principal prefer richer agents. Moreover, we show that, for an interesting class of problems, the principal prefers a relatively poorer agent if agent's wealth is sufficiently large. Finally, we discuss how alternative ways of modeling the agent's outside option affects the principal's preferences for agent's wealth.     

Measuring the economic impacts of major sports events: the case of Formula One Grand Prix (F1)

This study was examined the new money generated from Formula One Grand Prix (F1) and the economic impacts of this new money on the host economy using input–output analysis. We find that the impact of the new money from non-local attendees or international attendees is more pronounced compared to that from local attendees. Also, F1 event appears to influence on sports-related industry as well as other industries such as manufacturing industry. Our findings suggest that the host cities should focus on increasing the non-local and international attendees in order to enhance the economic impacts of a sport event.
