Drop-the-loser design in the presence of covariates

In the present work we develop a randomized two-treatment adaptive allocation design with covariates ensuring smaller variability of treatment allocations. We study, both numerically and theoretically, several exact and limiting properties of the design and consider an inferential problem following the allocation design. We compare the design with some of the existing allocation designs by computing its various performance measures.     

Ethical Leadership,Organic Organizational Cultures and Corporate Social Responsibility: An Empirical Study in Social Enterprises

While recent studies have increasingly suggested leadership as a major precursor to corporate social responsibility (CSR), empirical studies that examine the impact of various leader aspects such as style and ethics on CSR and unravel the mechanism through which leadership exerts its influence on CSR are scant. Ironically, paucity of research on this theme is more prevalent in the sphere of social enterprises where it is of utmost importance. With the aim of addressing these gaps, this research empirically examines the interaction between ethical leadership and CSR and, in addition, investigates organic organizational cultures (clan culture and adhocracy culture) as mediators in the above interaction. To this end, a model was developed and tested on the sample of 350 middle- and top-level managers associated with 28 Indian healthcare social enterprises, using Structural Equation Modeling Analysis, Bootstrapping and PROCESS. Results reveal that ethical leadership both directly and indirectly influences CSR practices. The indirect influence of ethical leadership involves nurturing clan and adhocracy cultures, which in turn influence CSR. These findings are significant for social enterprise leaders seeking to encourage their organizations’ socially responsible behavior.     

Developments in Consumer Protection in India

This paper surveys the major developments in the field of consumer protection in India since 1984, when the statutory provisions for regulating unfair trade practices were incorporated for the first time.Among the developments described in the paper is the strengthening of provisions for consumer protection through amendments to the Act regulating restrictive and monopolistic trade practices (the MTRP Act). Public-sector undertakings and co-operative societies have been brought within the purview of the Act, and consumers have obtained the right to participate in inquiry proceedings before the MRTP Commission.Consumers and their associations have been given the right to seek redress of grievances arising out of the violation of certain pieces of legislation, including the Drugs and Cosmetics Act. The Consumer Protection Act, 1986, was enacted in order to provide speedy and inexpensive redress of consumers' grievances. Redress can now be sought before any consumer court also for negligence or deficiency in medical services.The Bureau of Indian Standards Act, 1986, has strengthened the measures for the standardisation and quality control of manufactured goods.A Consumer Welfare Fund has been set up to provide financial assistance to voluntary consumer organisations and for the general development of consumer movement in the country. A spurt in voluntary consumer organisations in different parts of the country can also be observed.Other developments include the establishment of a separate Department of Consumer Affairs in the Union Government and the setting up of a Consumer Product Testing Laboratory.     

Singapore and the New Regionalism: Bilateral Trade Linkages with Japan and the US

Free Trade Areas (FTAs) have recently become an integral part of Singapore trade policy. This paper discusses the reasons behind Singapore's recent embracement of ‘new regionalism’ with particular reference to the proposals to form FTAs with Japan and the US. The paper goes on to examine various aspects of Singapore's trade linkages with the two economic superpowers in some detail. Popular discussion of FTAs gives one the appearance that such a trade policy is entirely benign. The paper sounds a cautionary note, highlighting some reasons to be concerned with Singapore's recent embracement of the ‘new regionalism’.     

Social media,an emerging platform for relationship building: A study of engagement with nongovernment organizations in India

The purpose of this study is to explore the major determinants of nongovernment organizations (NGOs) engagement and relationship building on social media in India. Netnography with a metaphoric grounded analysis is used for the data analysis to identify these determinants, and a conceptual framework is proposed to inform the strategic direction of NGOs. The findings suggest that supporters engage with NGOs largely for personal and organizational reasons. Emotions, trust, and information needs emerge as the primary personal drivers for engagement, whereas organizational accountability, performance, brand image, and transparency emerge as organizational drivers. Behavioural intention mediates the relationship between the drivers of engagement and supporter contributions. The study suggests that as the number of supporters on social media platforms is rapidly increasing, NGOs should recognize the importance of the supporter experience while designing their marketing strategies. Given the peculiarity of supporter behaviour in relationship building by NGOs, the inclusion of more supporters may improve the welfare of society.     

Can total factor productivity explain value added growth in services?

This paper examines the factors responsible for generating the services led growth witnessed in the Indian economy during 1980–2005. A sectoral growth accounting exercise shows that total factor productivity (TFP) growth was the fastest for services; moreover this TFP increase was significant in accounting for service sector value added growth. A growth model with agriculture, industry and services as three principal sectors is calibrated to Indian data using sectoral TFP growth rates. The baseline model performs well in accounting for the evolution of value added shares and their growth rates, but is unable to capture sectoral employment share trends. The performance of the model with respect to value added shares improves when the post 1991 increase in service sector TFP growth following the inception of market-based liberalization reforms is accounted for. A modified version of the model with public capital can better track trends in sectoral employment shares.     

Board structure and role of monitoring committees

Regulators and researchers alike have focused significant attention on the structure of the corporate board. In general, the results of prior empirical studies suggest that larger boards are costly to firms because of communication and co-ordination problems. How firms use committees to mitigate these costs, however, has not received as much attention. Since boards delegate authority for specific tasks to monitoring committees with independent directors, we re-examine the impact of board structure on firm performance by specifically focusing on the number of monitoring committees. Using ROA and EVA, we find that board size is positively associated with firm performance when firms use more than three monitoring committees. We also find that the previously documented negative association between board size and Tobin's Q disappears when a firm uses more than three monitoring committees. Overall, the results suggest that firms use monitoring committees to mitigate the costs associated with larger boards.     

Development of Research in Experimental Design in India

Cet article présente un panorama de la recherche indienne des 70 dernières années dans le domaine des plans d’expériences. Le travail accompli dans ce cadre est considérable, tant par le volume que par l'importance des contributions, et nous nous sommes attachés à en présenter un historique cohérent. Les sujets traités incluent les carrés latins mutuellement orthogonaux, les plans en blocs incomplets, les plans factoriels, les plans factoriels fractionnaires, les surfaces de réponse, les plans mixtes, les plans ligne‐colonne et les études croisées.     

A multi-criteria approach to local tax planning

A city tax model based on the analytic hierarchy process is developed. This model allows city officials to explicitly take into account the existence of multiple decision criteria in selecting new tax options. Opinions from tax experts are used to relate tax plans to decision criteria. The paper explores the feasibility of applying commonly available decision tools to facilitate and improve decision making in local government.
