The Expected Stock Returns of Malaysian Firms: A Panel Data Analysis

Pandey I M

We used panel data set of 1729 observations (247 Malaysian companies listed on the Kuala Lumpur Stock Exchange for 1993-2000) to identify variables that could explain expected returns of Malaysian stocks. Our results are based on the fixed effects regression model as it performed better than the random effects model and OLS model without the firm effects. Results of the fixed-effect univariate regressions indicated that beta, size, book-to-market value (B/M) ratio, earnings-price (E/P) ratio and dividend yield individually played a significant role in explaining stock returns and payout and leverage had no effect. The explanatory power of size (natural log of market capitalisation) was the highest. The fixed-effect multivariate regression results showed that size was persistently a significant dominant variable together with other variables in explaining stock returns. Beta was found to have consistently a positive relation with stock returns by itself and together with other variables. But its explanatory power was less than size and other variables. Contrary to the results of Fama and French (1992), B/M ratio was not persistently a significant variable; its significance disappeared when we incorporated size and E/P ratio in regression.

An Empirical Examination of the Characteristics of the Integration Responsiveness Pressures

Devinney Timothy M, Midgley David F, and Venaik Sunil

Although the integration-responsiveness framework has been used extensively in the international business and strategy literature, empirical validation of the framework has largely focussed on the strategy and structure of MNCs in response to the environmental pressures confronted by the firm. There have been few attempts to directly investigate the characteristics of the diverse environmental pressures confronted by multinational firms as they conduct their value creating activities worldwide. In this study, we propose five factors to examine in detail the characteristics of the integration-responsiveness pressures. These are depth, dimensionality, direction, distinctiveness and dynamic. Using data from MNC subsidiaries, we empirically test the nature of the environmental pressures that impact on MNC strategy and organisation. Based on our findings, we propose an alternative representation of the integration responsiveness framework that is more meaningful, useful and consistent with the contemporary behavior of MNCs than the current framework. In particular, the alternative representation isolates the issues of strategy and structure from that of the business environment and overcomes the recurrent problem of confounding among these concepts in the literature. Second, the proposed IR framework better captures the trade-off between integration and responsiveness that needs to be managed to operate global businesses. Finally, in contrast with the current IR framework wherein the environmental pressures are a priori classified as GI or LR thus making the framework static and rigid, the alternative framework is dynamic and flexible as it allows the pressures to be classified as GI, LR or both contingent upon the nature of the business, firm, function, task, country and customer segments, and over time.

Analysis of Claims and Reimbursements made under Mediclaim Policy of the General Insurance Corporation of India

Reuben Elan and Bhat Ramesh

Mediclaim insurance run by government owned insurance company General Insurance Corporation of India (GIC) is the only private voluntary health insurance scheme available in India currently. This scheme has been in operation since 1986 and from time to time a number of revisions have been carried out to address the needs of their clients. The documentation on claims and reimbursement of this scheme is scanty. This paper analyses 621 claims and reimbursements data pertaining to policy initiation years 1997-98 and 1998-99 of Ahmedabad branch of one of the subsidiary companies of the General Insurance Corporation of India. The analysis suggests that the number of policies and premiums collected have grown at significant rates, more than 30 per cent during 1998-99 and 50 per cent during the year 1999-00. The growth had implications for the management of scheme in terms of problems of adverse selection or provider induced demand and falling premiums per insured person. It was found that the number of claims increased by about 93 per cent during the year 1998-99 when polices sold grew at 32 per cent. The study estimates that about 1/3rd of claim amount increase is because of the problems of adverse selection or provider induced demand. The analysis of break-up of reimbursements suggests that about 40 per cent of reimbursements are made towards doctors fees. This is followed by diagnostic charges, which accounts for about 30 per cent. This makes the insurance claims highly vulnerable to provider-induced use of resources. The findings also suggest that the insurance company took on an average 121 days to settle the claim. It is pointed out given the demand side and supply side imperfections in the healthcare markets and absence of appropriate regulatory mechanisms in place, the Insurance and Development Regulatory Authoritys proposal to ensure payment settlement within 7 days is highly ambitious. The study also analyses reasons for the delay and cases where reimbursements have been less than claims submitted.

Experiences of Various Forms of Commercial Partnerships in Indian Railways

G. Raghuram

This paper brings out issues of governance between the Ministry of Railways and various service delivering commercial entities under the Ministry. Some of this is accentuated by both the ministerial and administrative powers vested in the same body, namely the Railway Board. We examine a set of eight case situations, wherein there has been an attempt to focus on a commercial approach. However, the extent of success/failure is varied. A study of these cases brings out the potential of improving railway infrastructure under a governance framework of (i) distancing the ministerial role from the commercial activity, (ii) increased private participation, (iii) improving transparency, contestability and competition, and (iv) appropriate regulations We describe salient features of each of the cases, with comments from the perspective of commercial viability. A concluding section brings out some of the key concepts which would be relevant for such commercial partnerships in the future. At a broader level, given the budgetary constraints, under exploited potential of the IRs assets and service possibilities, lack of commercially oriented professional and accountable management, such commercial partnerships have implicitly been accepted (by both the central government and the top management of IR) as the way forward.

Hospital Efficiency: An Empirical Analysis of District and Grant-in-Aid Hospitals in Gujarat

Reuben Elan, Verma Bharat Bhushan, and Bhat Ramesh

This study focuses on analysing the hospital efficiency of district level government hospitals and grant-in-aid hospitals in Gujarat. The study makes an attempt to provide an overview of the general status of the health care services provided by hospitals in the state of Gujarat in terms of their technical and allocative efficiency. One of the two thrusts behind addressing the issue of efficiency was to take stock of the state of healthcare services (in terms of efficiency) provided by grant-in-aid hospitals and district hospitals in Gujarat. The motivation behind addressing the efficiency issue is to provide empirical analysis of governments policy to provide grants to not-for-profit making institutions which in turn provide hospital care in the state. The study addresses the issue whether grant-in-aid hospitals are relatively more efficient than public hospitals. This comparison between grant-in-aid hospitals and district hospitals in terms of their efficiency has been of interest to many researchers in countries other than India, and no consensus has been reached so far as to which category is more efficient. The relative efficiency of government and not-for-profit sector has been reviewed in this paper. It is expected that the findings of the study would be useful to evaluate this policy and help policy makers to develop benchmarks in providing the grants to such institutions.
