A state‐level analysis of the economic impacts of medical tourism in Malaysia

In Malaysia, a country that ranks among the world's most recognised medical tourism destinations, medical tourism is identified as a potential economic growth engine for both medical and non‐medical sectors. A state‐level analysis of economic impacts is important, given differences between states in economic profiles and numbers, origins, and expenditure of medical tourists. We applied input–output (I–O) analysis, based on state‐specific I–O data and disaggregated foreign patient data. The analysis includes nine of Malaysia's states. In 2007, these states were visited by 341,288 foreign patients, who generated MYR1,313.4 m ($372.3 m) output, MYR468.6 m ($132.8 m) in value added, and over 19,000 jobs. Impacts related to non‐medical expenditure are more substantial than impacts related to medical expenditure, and indirect impacts are a substantial part of total impacts. We discuss management and policy responses and formulate recommendations for data collection.     

An application of finite elements to option pricing

This study applied the finite element method (FEM) to pricing options. The FEM estimates the function that satisfies a governing differential equation through the assembly of piecewise continuous functions over the domain of the problem. Two common representations, a variational functional representation, and a weighted residual representation are used in the application of the method. The FEM is a versatile alternative to other popular lattice methods used in option pricing. Advantages include the abilities to directly estimate the Greeks of the option and allow nonuniform mesh construction. As an illustration of the advantages that the FEM offers, the method was used to price European put options and discrete barrier knock‐out put options. © 2001 John Wiley & Sons, Inc.

An analysis of the liquidity benefits provided by secondary markets

Listing shares in liquid secondary markets either to facilitate acquisitions or to diversify owner’s personal wealth are among the most important reasons for firms to go public [Brau, J.C., Fawcett, S.E., 2006. Initial public offerings: An analysis of theory and practice. Journal of Finance 61, 399–436]. We contend that the expected benefits derived from the liquidity provided by secondary markets are relevant for understanding important decisions made in preparation for an IPO. We hypothesize that the potential losses caused by an IPO failure induce firms that benefit more from going public to hire more reputable underwriters and to adopt more conservative pricing policies. We use several proxies for the benefits firms derive from post-IPO liquidity. The results indicate that firms that benefited more from liquidity were taken public by more prestigious underwriters and exhibited substantially larger levels of price revisions and underpricing. Post-IPO liquidity is also important for understanding the decision to retain the lead underwriter in subsequent SEOs.     

External Economies in Procyclical Productivity: How Important Are They?

Using the method of Caballero and Lyons (1990,1992), I examined detailed Swedish manufacturing firm-level dataon output and factor inputs from 1979 through 1994. Panel regressionsshow that an increase in aggregate output and inputs appearsto raise individual firms' production beyond private marginalreturns, a result consistent with positive external effects fromaggregate activity. However, while considering potential specificationdifficulties, this analysis shows that a model in which high-frequencyexogenous shifts in technology drive the business cycle statisticallyoutperforms the Caballero-Lyons model. This finding suggeststhat economywide fluctuations in technology are more importantfor movements in firms' productivity than are external economies.     

Market orientation, employee development practices, and performance in logistics service provider firms

Although the utilization of logistics service provider firms is growing exponentially in business-to-business markets, little is known about what enables some of these firms to perform better than others. Building on the resource-based view of the firm, this research proposes that market orientation and certain employee development practices (service-related training, coaching, and empowerment) influence both employee and organizational performance. The hypotheses are tested using data from 123 large logistics service provider organizations. A multi-survey design was utilized wherein managers as well as the frontline service employees who interact directly with customers represented each organization. The findings suggest that (a) market orientation influences organizational and employee performance, (b) coaching moderates both links, (c) service-related training moderates the link with employee performance only, and (d) empowerment does not moderate either link.     

Cross-national research and international business: An interdisciplinary path

Comparative cross-national research is among the oldest approaches of scientific inquiry in the social sciences. We investigate the foundations of published works in cross-national research (CNR) in international business (IB), sociology, and psychology with an eye on leveraging their rich traditions for future IB research. Our approach aims to contribute and address repeated calls for taking an interdisciplinary approach in IB. We examined published CNR in 106 scholarly journals and identified 817 articles with 51,738 citations in IB, 477 works with 30,017 citations in sociology, and 835 articles with 54,519 citations in psychology. We use metric multidimensional scaling to examine the co-citation data for each field and identify knowledge and approaches commonplace in sociology and psychology to propose future research paths in IB. In particular multilevel analysis, which is scarcely used in IB, offers the potential of unfolding new dimensions within the field. Based on the emergent results from our MDS solutions, we recommend multiple future paths for CNR, particularly with respect to IB relationships, market entry, and related domains.     

Structural reforms and growth in transition

The present fiscal difficulties of many countries amplify the call for structural reforms. To provide stylized facts on how reforms worked in the past, we quantitatively review 60 studies estimating the relationship between reforms and growth. These studies examine structural reforms carried out in 26 transition countries around the world. Our results show that an average reform caused substantial costs in the short run, but had strong positive effects on long‐run growth. Reforms focused on external liberalization proved to be more beneficial than others in both the short and long run. The findings hold even after correction for publication bias and misspecifications present in some primary studies.     

MEAN–VARIANCE PORTFOLIO OPTIMIZATION WITH STATE‐DEPENDENT RISK AVERSION

The objective of this paper is to study the mean–variance portfolio optimization in continuous time. Since this problem is time inconsistent we attack it by placing the problem within a game theoretic framework and look for subgame perfect Nash equilibrium strategies. This particular problem has already been studied in Basak and Chabakauri where the authors assumed a constant risk aversion parameter. This assumption leads to an equilibrium control where the dollar amount invested in the risky asset is independent of current wealth, and we argue that this result is unrealistic from an economic point of view. In order to have a more realistic model we instead study the case when the risk aversion depends dynamically on current wealth. This is a substantially more complicated problem than the one with constant risk aversion but, using the general theory of time‐inconsistent control developed in Björk and Murgoci, we provide a fairly detailed analysis on the general case. In particular, when the risk aversion is inversely proportional to wealth, we provide an analytical solution where the equilibrium dollar amount invested in the risky asset is proportional to current wealth. The equilibrium for this model thus appears more reasonable than the one for the model with constant risk aversion.     

Toward a theory of the boundary-spanning marketing organization and insights from 31 organization theories

Now more than ever, marketing is assuming a key boundary-spanning role—a role that has also redefined the composition of the marketing organization. In this paper, the marketing organization’s integrative and mutually reinforcing components of marketing activities, customer value–creating processes, networks, and stakeholders are delineated within their boundary-spanning roles as a particular emphasis (labeled MOR theory). Thematic marketing insights from a collection of 31 organization theories are used to advance knowledge on the boundary-spanning marketing organization within four areas—strategic marketing resources, marketing leadership and decision making, network alliances and collaborations, and the domestic and global marketplace.
