An Exponential Neighborhood Local Search Algorithm for the Single Row Facility Location Problem

Diptesh Ghosh

In this work we present a local search algorithm for the single row facility location problem. In contrast to other local search algorithms for the problem, our algorithm uses an exponential neighborhood structure. Our computations indicate that our local search algorithm generates solutions to benchmark instances of the problem whose costs are on average within 2% of costs of optimal solutions within reasonable execution time.

High-Value Agriculture in India:
Past Trends and Future Prospects

Vijay Paul Sharma and Dinesh Jain

Given the declining share of traditional agricultural commodities in production, consumption and trade, horticulture and other non-traditional high-value agriculture represent an important area of potential income growth in rural areas. The high-value agriculture-led-growth strategy also provides significant scope for achieving greater commercialization of smallholder agriculture. Despite the potential, the contribution of high-value agricultural exports is still small but increasing. This paper examines the past and existing performance and identifies likely challenges and opportunities for high-value-agriculture in the country.
The findings of the study reveal a structural shift in consumption pattern away from cereals to high-value agricultural commodities, both in rural and urban areas, in the last two decades. This shift in dietary patterns across states and income classes is also observed. The results reveal a relatively strong and growing demand for livestock products and fruits and vegetables in both rural and urban areas. The average expenditure as well as share of beverages has increased by about six times in both rural and urban areas. Due to shift in demand pattern towards high-value crops, the farmers have also responded to market signals and gradually shifting production-mix to meet the growing demand for high-value commodities. This is reflected in the changing share of high value crops in total value of output from agriculture. The share of high-value commodities/products (fruits and vegetables, livestock products, fisheries) increased from 37.3 percent in Triennium Ending (TE) 1983-84 to 41.3 percent in TE 1993.94 and reached a level of 47.4 percent in TE 2007-08. The trade in high-value products has also increased during the last decade. Overall, fresh fruits and vegetables exports represent a very small share of domestic production and agricultural exports but have increased significantly. During the 2000s, the growth rate in value of exports of rice, sugar, marine products, tea, etc. declined, while high-value exports (fruits and vegetables, floriculture, meat, processed fruit juices) grew by about 18 percent annually. However, Indian exports face many constraints in major importing countries on account of quality and food safety issues. The rising demand for high-value commodities, particularly fruits and vegetables and livestock products has led to an increase in imports of many commodities like fresh fruits. While there is an opportunity for increasing exports of high-value products but there is a huge and increasing domestic demand which needs to be tapped.
The study suggests that a future road map for high-value agriculture development should focus on investment in technology development and dissemination, basic infrastructure, improvement of technical capacity of producers and other players in the value chain, institutional support in core functions of production, logistics and marketing through concerted public sector support and active public-private partnerships, and provision of quality inputs, in particular planting materials for fruits and seeds for vegetables.

Speed of Adjustment and Inflation – Unemployment Tradeoff in Developing Countries – Case of India

Ravindra H. Dholakia and Amey Sapre

This paper estimates the short-run aggregate supply curve for the Indian economy over the period 1950-51 to 2008-09. Methodological improvements in this paper include the technique of estimating adaptive expectations, constrained estimation consistent with long run equilibrium, and introduction of the extended Phillips curve. The study also attempts to investigate the question of speed of recovery and the choice of adjustment paths available to policymakers in face of adverse supply shocks. In order to estimate the inflation-unemployment tradeoff we estimate the regular Phillips curve which lies at the root of the aggregate supply curve. The estimation is based on using adaptive inflationary expectations and supply shocks. We further introduce the extended part of the Phillips curve to analyze the question of speed of recovery and the choice of adjustment path. Contrary to previous studies, the present study finds a regular tradeoff between inflation and output or unemployment with inflationary expectations based on the experience of past three to four years. We also find that the subtle tradeoff between the rate of output recovery and inflation is negative in India thereby implying that a strategy of fast recovery is not likely to result in high inflationary pressures. These findings have important implications for policy choices on growth and strategy for recovery. The current fiscal and monetary policy stance has been strictly anti-inflationary and recognizes that some short-run deceleration in growth is unavoidable for controlling inflation. These policies without any empirical support presuppose the existence of a tradeoff between inflation and output and the choice of strategy for recovery. Our findings show that a strategy of slow recovery and following demand contraction policies to control inflation during the recovery phase could be counterproductive.

Board Interlocks and Their Impact on Corporate Governance: The Indian Experience - Coping with Corporate Cholesterol

Bala N. Balasubramanian, Samir K. Barua, Suresh Bhagavatula, and Rejie George

Board interlocks occur when a director of one organization sits on the board of directors of another organization. The causes and consequences of these interlocks have been much debated in the western literature but comparatively little is known about interlocks in Indian corporate boards. Board interlocks are essentially analogous to cholesterol. Both are facts of life. Like good cholesterol, there are aspects of interlocking directorates that are beneficial and there are others that are detrimental to the corporation and its stakeholders and their respective interests.

In this study, we find that board interlocks are quite widespread in India. Taking a (numerically) small but nevertheless (in terms of market capitalization) an important slice of available corporate data, we observed that in 2010, 'highly boarded' directors (defined as those on the board of 5 or more listed NSE companies) who constitute just 6 percent of the overall pool of directors among NSE100 companies are associated with 486 NSE listed companies which account for a whopping 66 percent of the total market capitalization of all NSE listed companies. Interestingly, there appears to be a marked increase in market capitalization of these 'highly boarded' companies, which these 'highly boarded' directors are linked to over the last several years. For instance, for the 3 years from 2001 to 2003, the market capitalization of 'highly boarded' companies ranged between 33 percent to 43 percent; it moved up to peak of 70 percent in 2007 and was at 66 percent in 2010 (the latest year in the study period). The substantive rise in market capitalization of these 'highly boarded' companies has coincided with only a marginal increase (from 5% to 6%) in the proportion of 'highly boarded' directorships.

These trends suggest that despite the well-intentioned regulatory reforms (a) the extent of over-boarding/interlocking among directors has not come down (there is actually a marginal increase) and (b) there appears to be increasing concentration of power among key individuals. Given the general view that concentration of power in a few individuals or entities is not desirable in the larger interests of society, it would appear that the observed trends in the concentration of power among a handful of the country's corporate elite is a matter for substantive public policy concern. Finally, the regression analysis indicates a positive impact on Return on Assets (ROA) for 'highly boarded' directors signifying a negation of the agency centric conceptualization on the role of multiple directors. Instead, connectedness variables (Eigen vector) which proxy for the Resource dependency hypothesis are quite strongly supported. In a nutshell, from public policy perspective, the analysis potentially reflects the 'bad cholesterol' elements of multiple directorships in terms of a tiny segment of 'highly boarded' directors controlling a significant portion of the country's economic prowess, whereas the positive influences on company performance provide some evidence of the 'good cholesterol'.

The Impact of Feminine Identity and Soft Influence
Tactics on Leadership Style

Asha Kaul and Jithesh K. Kumar

Using sex identity theory, the paper studies the impact of feminine identity and soft influence tactics on leadership styles, specifically task oriented and participative. Earlier researchers have documented difference in the working and leadership styles of men and women and tactics used for securing compliance from team members. Yet there are few studies which have proceeded beyond an understanding of leadership styles which are based on the "psychosocial" behavior of men and women stemming from their sex identity, defined in terms of "masculinity" and "femininity". The results from 379 subjects from four different sectors show that there is a significant correlation between feminine identity and soft influence tactics which directly impact the leadership styles of men and women. We posit that these leadership styles are not gender specific but defined by the identity of the leader and the situational requirements.

Access of the Rural Poor to Primary Healthcare in India

Shreekant Iyengar and Ravindra H. Dholakia

The 11th Five-Year Plan of India emphasizes the wider and better coverage of services, such as primary healthcare for the majority of population. For this purpose, various healthcare related programmes have aimed at the vulnerable sections of the society traditionally using social criteria like SC and ST populations. Although they are found to have marginally worse health outcomes than the national average, they are far better than the one's for the poor on economic criteria. The present paper examines the coverage of basic primary healthcare services among the BPL population in rural areas of six states in India to provide a direct empirical evidence. The results of the survey showed that the coverage of primary healthcare services, such as antenatal care, institutional deliveries, and immunization was very low among the BPL population. The focus of the programme for improving coverage of primary healthcare services should be on the BPL population. If it is done, it would result also in the improvement of coverage among the SC/ST population. Merely focusing on the SC/ST population will, however, leave the poorest of the poor ignored and unattended.

A Voice for the Voiceless: Peer-to-peer Mobile Phone Networks
for a Community Radio Service

Kavitha Ranganathan and Ankur Sarin

We propose a new application for mobile ad-hoc networks (MANETs)-community radio. We argue how MANETS help overcome important limitations in how community radio is currently operationalized. We identify critical design elements for a MANET based community radio service and propose a broad architecture for the same. We then investigate a most critical issue- the choice of the network wide broadcast protocol for the audio content. We identify desired characteristics of a community radio broadcasting service. We choose and evaluate eight popular broadcasting protocols on these characteristics, to find the protocols most suited for our application.

Estimating the Contribution of Infrastructure in Regional
Productivity Growth in India

Astha Agarwalla

There does not seem to be a consensus on the importance of infrastructure investments in the process of economic development. With persistent regional disparities, and increasing regional identities, there is a need to determine the drivers of regional growth. Contribution of infrastructure to regional productivity growth is analyzed in this paper. Empirical analysis using data from 25 states in India for the past two decades suggests that composition of infrastructure investment is important in facilitating economic growth. Empirical results also highlight that investments in economic infrastructure have the closest linkage with regional productivity growth.

Institutional Innovations and Models in the Development of
Agro-Food Industries in India: Strengths, Weaknesses and Lessons

Vasant P. Gandhi and Dinesh Jain

Agro-industries are given high priority in India particularly because of their great potential for contributing to development. The emphasis on village-based agro-industries was introduced almost a century ago in India by Mahatma Gandhi as an important ideology and corner-stone of the independence movement. The approach has undergone substantial transformation since then, but major challenges to its success in development remain: how to organize sustained production and procurement from large numbers of small farmers, how to ensure adoption of the right technology and practices to generate quantity and quality output at a reasonable cost, how to obtain capital for ensuring good processing technology and meeting the high working capital requirements in a fluctuating business, how to deliver strong marketing efforts to compete and open nascent markets, and how to ensure effective ownership, management and control to ensure performance for its main stakeholders of producers, consumers and investors. To address these challenges, effective institutional frameworks are a must, and a number of innovations and institutional models have emerged in India. These include the HPMC model, the AMUL model, the Pepsi model, the E-choupal model, the Nestle model, the Heritage model, the Suguna model, the Reliance model and more. The paper uses available literature and data to examine the performance of several of these models with respect to the above mentioned challenges. Many findings and lessons emerge which would be useful for business and for guiding supportive policies and practices in developing countries.

Equity Markets with Controlling Shareholders

Sidharth Sinha

In early 2008 the Finance Ministry issued a consultation paper on "Requirement of Public Holding for Listing". The Finance Minister also declared in his 2009-10 budget speech that the threshold for non-promoter public shareholding for all listed companies would be raised in a phased manner. This paper discusses the cross-country research on concentrated share ownership and household participation in equity markets. The paper argues that instead of 'forcing' controlling shareholders to dilute their positions the government can achieve its objective more effectively by enhancing minority investor protection in the short run and creating more owners by improving the "Ease of doing business" in the long run.
