Which country matters? Institutional development and foreign affiliate performance

This article investigates the effect of the level of institutional development of host countries on the level of and variation in foreign affiliate performance. Institutional development is defined as the extent to which the economic, political, and social institutions in a host country are developed and are favorable for foreign affiliates. A longitudinal analysis of over 30,000 foreign affiliate‐year cases that include 6,985 foreign affiliates in 38 host countries between 1996 and 2001 shows that foreign affiliate performance varies noticeably both across and within host countries. The results suggest that the level of institutional development, as determined by the Institutional Development Index (IDI), a new measurement developed in this study, has a strong negative curvilinear relationship with the variation in foreign affiliate performance and a negative effect on the level of foreign affiliate performance. The implications for future research, practice, and policymaking are discussed. Copyright © 2008 John Wiley & Sons, Ltd.     

Does country matter?

Previous studies have explored the predictors of business unit performance in multiple‐business firms and investigated the extent of the effect of industry, corporate, and business unit on the performance of a business unit. These studies have focused almost exclusively on examining performance differences within a single country, thus treating country effects as external to business unit performance. In contrast, this study focuses on multinational corporations and examines the extent to which country effects explain the variation in the performance of foreign affiliates. Our findings show that country effects are as strong as industry effects, following affiliate effects and corporate effects. Our results also suggest that corporate and affiliate effects tend to be more critical in explaining the variation in foreign affiliate performance in developed countries, whereas country and industry effects are more salient in developing countries.

Duplicating and Pricing Contingent Claims in Incomplete Markets

The paper studies the problem of pricing contingent claims in the situation where the constraints imposed on an investor's portfolios are important. There are two types of rule of constraint: under a rigid rule, an investor must strictly limit his portfolios inside the constraint; under an elastic rule, an investor pays a penalty when the constraint is violated. The central problem of pricing a contingent claim is to determine the initial investment required to duplicate the contingent claim. The following results are obtained: (i) under elastic rules, the cost to duplicate a contingent claim exists and is unique;(ii) this cost depends nonlinearly and convexly on the contingent claim;(iii) the cost under rigid rules resulting from passing the penalty to infinity is also a nonlinear and convex function of the contingent claim. Owing to this nonlinearity, the cost of duplication may be or may not be the nonarbitrage price of the contingent claim; this depends on how the market organizes the production of contingent claims. The conclusion that the cost of duplication is a convex function of the contingent claim provides an explanation for why the service of providing contingent claims is often a highly profitable business. The main mathematical tool in the analysis is backward stochastic differential equations (BSDEs). In fact the cost to duplicate a contingent claim is the solution of a BSDE in which the contingent claim is the terminal value.     

The Timing of International Expansion: Information, Rivalry and Imitation Among Japanese Firms, 1980–2002

abstract    Sociological-based information theory and economics-based competitive rivalry theory operate as the dominant theories of interorganizational mimetic behaviour. Recent work has sought to integrate the ideas in these theories, or determine which has greater explanatory power. In this study, we juxtapose the concepts in these two theories, to illustrate the complementary nature of information-based and rivalry-based theories of mimetic behaviour. Specifically, we consider how the predictions of information-based theories are moderated by the home competitive context of the industry of a firm making an international expansion. Using a 1980 to 2002 sample of 4949 manufacturing plant entries made into 71 foreign countries by 783 publicly-listed Japanese manufacturing firms, we find that the competitive context in the home industry influences the propensity of a focal firm to imitate the actions of rival firms. Our results support our contention that the two theoretical approaches are complementary, with the complementarities extending from the limitations of each approach.     

The characteristics and performance of Japanese FDI in less developed and developed countries

Data on 26,857 Japanese foreign investments in 150 countries and regions over the 1991–1999 period reveal that there are stark differences in the characteristics and performance of Japanese FDI (JFDI) between less developed countries (LDCs) and developed countries (DCs). JFDI in LDCs has been growing more rapidly over the period, and it is concentrated in the Secondary industrial sector, with a lower level of control within a subsidiary, and has been initiated by parent firms with market-seeking and labor-seeking purposes and with relatively weak ownership advantages. In contrast, JFDI in DCs has maintained relatively stable growth over the period, is concentrated in the Tertiary industrial sector, with a higher level of control within a subsidiary, and has been initiated by parent firms with market-seeking and strategic-seeking purposes and with relatively strong ownership advantages. JFDI in LDCs tended to attain a higher financial performance and a lower exit rate, yet with a greater variance, than those in DCs.     

Cost-effectiveness of mechanical thrombectomy for acute ischemic stroke: an Australian payer perspective

Aims: The goal of this study was to assess the cost-effectiveness of mechanical thrombectomy (MT) for acute ischemic stroke (AIS) from an Australian payer perspective.

Methods: This study used a Markov model that employed a life-time time horizon, modeling patients from symptom onset of stroke until end of life. Clinical efficacy and safety data were taken from an individual patient level data (IPD) meta-analysis of clinical studies. The treatment effect of MT compared to usual care was measured by changes in modified Rankin Score (mRS). Post-treatment mRS scores were used to determine short- and long-term stroke care costs. Treatment costs were modeled, with health state utility values determined by literature review. All analyses were conducted using Microsoft Excel.

Results: In comparison to usual care, MT is associated with higher costs ($10,666 per patient) and additional quality-adjusted life years (QALYs) (0.8281 per patient), resulting in an incremental cost per QALY of $12,880. Sensitivity analyses demonstrated the reliability of the base case results across a range of assumptions. The higher cost associated with MT is, to an extent, offset by the cost savings resulting from lower stroke care costs due to improved patient outcomes. The life-time cost savings in terms of stroke care costs are estimated to be more than $8,000 per patient for patients who had received MT in combination with usual care.

Limitations: Stroke care costs based on patient disability/functional level were not available and were derived. As a consequence, long-term care costs for patients with poorer outcomes may be under-estimated. Patient outcomes at 90 days were extrapolated to a lifetime horizon, but this approach was supported by long-term evidence on stroke survival.

Conclusions: Mechanical thrombectomy is a cost-effective treatment option for AIS, with clinical benefits translating to short- and long-term cost benefits. This analysis supports rapid update of stroke care pathways to incorporate this therapy as a treatment option.

Skew and heavy‐tail effects on firm performance

Research summary : Most strategic management studies adopt an average‐centered view that uses the central tendency to explain between‐group variation in performance (i.e., performance differences between business units, firms, industries, and countries). In this study, we explain within‐group variation using a variance‐centered view that focuses on the peripheral characteristics of performance distributions as defined by skew and heavy tails (i.e., variance and kurtosis). Drawing on performance feedback theory, we hypothesize that successful firms tend to develop a positive skew in their performance distributions, which we call a “positive skew effect” in this study, and that heavy tails moderate this effect. Our analysis of the performance of a group of foreign affiliates provides general support for our hypotheses at both the firm and segment (industry and country) levels. Managerial summary : Managers of multi‐business firms use various approaches to improve the aggregate performance of their business units. Some expand the range of upper performance outliers (exploration) or reduce the range of lower outliers (downsizing); others improve the performance of current business units (exploitation). We find that firms with superior performance tend to have a balanced mix of the three approaches. We also find that segments (countries and industries) with higher mean performances provide environments that facilitate the entry of productive firms and the exit of unproductive firms and provide environments in which incumbents can further improve their performance by learning from others. We observe that successful firms and segments have a positive skew in their performance distributions, which we call a “positive skew effect.” Copyright © 2016 John Wiley & Sons, Ltd.
