Corporate Risk Management under Information Asymmetry

This paper examines the financial and operational hedging activities of US pharmaceutical and biotech firms that are subject to a high level of information asymmetry stemming from R&D investments during 2001–2006. We find evidence in support of the information asymmetry hypothesis à la Froot, Scharfstein and Stein (1993) that hedging helps mitigate the under‐investment problem. Specifically, we find that the use of financial derivatives is associated with greater firm value and that the value enhancement is larger for firms subject to greater information asymmetry and better growth opportunities. There is a synergy between financial hedging and operational hedging where the latter is used to counter product development risk. The results are robust with respect to alternative performance measures, industry‐specific growth measures, and the endogeneity problem. Our work is differentiated from existing studies that examined commodity‐based industries without addressing information asymmetry.     

The Economics of Director Heterogeneity

We investigate the potential costs and benefits of firms constituting a heterogeneous pool of directors relative to more homogeneous boards. We measure director heterogeneity along six separate dimensions and divide board heterogeneity into occupational and social components. Our empirical analysis indicates that corporate complexity and managerial control exhibit significant influence on board heterogeneity. Using the heterogeneity of the county population of the firm's headquarters as an instrument, we also find that investors place valuation premiums on heterogeneous boards in complex firms but discount heterogeneity in less complex firms. Overall, our analysis indicates greater heterogeneity may not necessarily improve board efficacy.     

Land-use changes, forest/soil conditions and carbon sequestration dynamics: A bio-economic model at watershed level in Nepal

A dynamic bio-economic model has been used at watershed level in Nepal to analyze the land-use changes, forest and soil conditions and their resultant impacts on carbon (C) sequestration. Planning horizon of the model extends over a period of 25 years. The objective function is maximization of the sum of discounted net income flows from agriculture, livestock and forestry productions; imputed value of leisure and labour hiring out activities subject to annual constraints on land, labour and capital availability along with the fulfilment of minimum cash and consumption requirements. The seven scenarios analyzed by the model are: business as usual (BAU), reduction in population growth rate from 2 to 1.5% p.a., increased prices of major crops by 10 and 20%, reduction in emigration of active labour force from the watershed from the current rate of 20–15 and 10%, and increase in discount rate from 5 to 10%. The results indicate that reduced labour emigration rates and increase in the prices of major crops lead to expansion of cultivated area and shift from one land use to the others. Land clearing becomes more severe with decline in labour emigration rate. Up to 10% increase in the prices of agricultural crops does not have noticeable effect on total land clearing. Increase in discount rate leads to less land clearing, more biomass harvesting and higher net C sequestration as compared to the BAU scenario. Assuming a C price of 10 USD per MgC and 5% discount rate, the net present value of C sequestration for the first 25 years is estimated at 1.83 mill USD in the BAU scenario, varying from 0.16 mill USD to 2.26 mill USD, as respectively the lowest and highest values for the seven scenarios analysed. A reduction in population growth and maintenance of current rate of off-farm employment are suggested for slowing down the expansion of cultivated land area, and thereby reducing the forest/soil degradation and C emissions. This in turn would enhance the income potential from C sequestration.     

India's New Economic Policy of 1991 and its Impact on Women's Poverty and AIDS

This paper examines the effects of current policies intended to liberalize the Indian economy and facilitate globalization on women close to poverty. The New Economic Policy of 1991 included standard structural adjustment measures including the devaluation of the rupee, increase in interest rates, reduction in public investment and expenditure, reduction in public sector food and fertilizer subsidies, increase in imports and foreign investment in capital-intensive and high-tech activities, and abolition of the cash compensatory support for exports. These policies have resulted in increased urbanization, and fewer job opportunities for women in the formal sector. Such conditions increase poverty for women in particular. As a result, many women flow into cities looking for work in the informal sector. This may have increased numbers of women in sex work, for lack of better economic opportunity. Sufficient data are not available to confirm whether HIV infection rates have risen as a result; however, the evidence suggests there may be a relationship between macroeconomic policies and health outcomes.     

Agricultural Productivity and Poverty Reduction in Nepal

This paper provides for the first time a clear quantitative link between agricultural productivity and poverty among rural households in Nepal. Using data from a nationwide Nepal Living Standard Survey 2004, we first estimate household‐specific productivity per worker under both Cobb–Douglas and translog production functions. Second, the paper identifies the determinants of productivity. Third, we explore a theoretical link between productivity and poverty using Sen's poverty index and find empirically that productivity growth substantially helps poverty reduction. Finally, the integrated effects of changes in productivity determinants are found to be stronger than the outcomes of sectoral policies taken in isolation.     

Subordinate board structures

The board of directors is a flat governance structure where each director has an equal vote in determining the collective actions taken by the group. Yet, some boards choose to delegate authority for specific tasks to numerous committees, while others choose to create relatively few subcommittees of the board. We investigate the determinants of subordinate board structures, exploring both their benefits and costs. Using a sample of the S&P 1500 we find that subordinate board structures are positively related to board size and the proportion of outside directors, even after controlling firm characteristics such as complexity and ownership structure. Further tests indicate that these board structures can offset the negative associations that board size and the proportion of outsiders can have with firm performance. Yet, in firms with relatively small or insider oriented boards, where co-ordination problems among directors or social loafing may be less pronounced, we find that subordinate board structures are negatively related to firm performance. Categorizing committees as either monitoring or advisory, we find that both types of committees appear related to firm performance. Taken as whole, these results are consistent with the idea that subordinate board structures can be a costly remedy to alleviate problems that arise with larger, more outsider dominated boards.     

A novel business strategies framework of do-it-yourself practices in logistics to minimise environmental waste and improve performance

The transportation sector is consuming a high quantity of oil and producing air pollution, CO₂ and allergies, as well as promoting the storage of goods in traditional warehouses. It is not only creating waste and environmental pollution but also increasing temperature, air pollution and low rainfall. The present study intends to uncover and understand the challenges of logistic infrastructure as well as how the adoption of do-it-yourself (DIY) business strategies is useful to encourage those practices and technology which are useful in transforming the logistic infrastructure into an eco-friendly environment. The DIY focuses on purposely utilising digital technologies to increase the engagement and involvement of customers in businesses. Moreover, DIY enables organisations to produce products and services that are highly demanded and have high acceptability. After doing an extensive literature review, the enablers of DIY are identified, and empirical investigation has been conducted. The analysis of the study provides a business strategies framework of DIY which would help the logistics managers in the proper implementation of the DIY practices to minimise negative environmental impact and improve business performance.     

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.     

Gender and ethnic diversity on boards and corporate information environment

Prior studies argue that demographic diversity on a firm's board impacts its information environment, yet there is limited empirical evidence regarding the relation between board diversity and corporate opacity. We extend this line of research by examining whether gender and ethnic diversity of directors impacts corporate opacity. Using a Herfindahl Index based on directors' gender and ethnicities to measure board diversity, and an opacity index based on analyst following, analyst forecast error, bid–ask spread, and share turnover to measure corporate opacity, we find that board diversity is negatively associated with corporate opacity. Our results are robust to alternative measures of board diversity and the various tests we employ to address potential endogeneity concerns.
