How farmers benefit from plant clinics: an impact study in Bolivia

Between 2000 and 2009, nine plant clinics in three agro-ecological areas of Bolivia (Andes, lowlands and valleys) served about 800 communities in an area roughly 300 × 100km. Over 6000 farmers consulted these clinics with 9000 queries. Many found the advice so useful that they visited the clinics repeatedly. A survey of 238 clinic users found that most adopted the clinics' recommendations. Fruit and vegetable growers who followed the clinic recommendations tended to spend less on pesticides. As for certain crops like potato, citrus and peach palm, a modest increase in pesticides helped improve the quality and quantity of the harvest. Farmers improved their incomes by following the clinics' advice. The poorest farmers enjoyed the greatest increase in income per hectare. This was the first study to explore the impact of plant clinics; future studies need to be improved, for example by obtaining baseline data and by comparing clinic users to their peers who have not used clinics.     

Application of an ecosystem function framework to perceptions of community woodlands

Owners, local residents, government, and conservation organisations can express divergent preferences in the development and management of local woodlands. The perceptions of these four groups were examined, in the context of three community woodlands in Eastern England, using an ecosystem function framework. In a pilot study, residents were able to allocate a relative importance to woodland ecosystem services which were then related to “regulation”, “habitat”, and “production” or “information” functions. However residents also placed importance on negative services or “dis-services” associated with the woodland ecosystem. Therefore a fifth category of “dis-services” was included in the main survey which included 84 local residents, three woodland owners, three government institutions, and six representatives from conservation groups. Each of the four groups placed greatest importance on services associated with habitat (16–39% of the total importance) and information (30–50%) functions suggesting, in this example, mutual interest in the use of woodlands as a habitat or recreational resource. By contrast a potential area of difference was the particularly high importance placed by one owner on dis-services such as fly tipping. In addition the woodland owners placed higher importance (10–20%), than local residents and conservation groups (7–9%), on the productive services of the wood. This suggests a need for communication when production-related operations affect recreation. The ecosystem function framework appears to be a useful approach for highlighting potential tensions and areas of mutual interest in the management of semi-natural ecosystems.     

No Body to Kick,No Soul to Damn: Responsibility and Accountability for the Financial Crisis (2007–2010)

This article takes the 2008–2010 financial crisis as a case study to explore the tension between responsibility and accountability in complex crises. I analyze the patterns of attribution and assumption of responsibility of thirty-three bankers in Wall Street, interviewed from fall 2008 to summer 2010. First, I show that responsibility for complex failures cannot be easily attributed or assumed: responsibility becomes diluted within the collective. Actors can only assume collective responsibility, recognizing that they belong to an institution at fault. Second, I show that blaming is a social process that should be examined contextually, relationally, and dynamically. I build on sociological theories to depart from the normative focus of philosophers, and the cognitive focus of psychologists, who have dominated the study of responsibility so far.     

Gender and Land Rights Revisited: Exploring New Prospects via the State, Family and Market

The question of women's land rights has a relatively young history in India. This paper briefly traces that history before examining why gendering the land question remains critical, and what the new possibilities are for enhancing women's land access. Potentially, women can obtain land through the State, the family and the market. The paper explores the prospects and constraints linked to each, arguing that access through the family and the market deserve particular attention, since most arable land in India is privatized. On market access, the paper makes several departures from existing discussions by focusing on the advantages, especially for poor women, of working in groups to lease in or purchase land; using government credit for land rather than merely for micro–enterprises; and collectively managing purchased or leased in land, the collectivity being constituted with other women, rather than with family members. Such group functioning is shown to have several advantages over individual or family–based farming. This approach could also help revive land reform, community cooperation and joint farming in a radically new form, one centred on poor women.     

Using Engel curves to measure CPI bias for Indonesia

To measure real income growth over time, a price index is needed to adjust for changes in the cost of living. The consumer price index (CPI) is often used for this task; but several country studies show that it is a biased measure of such changes, leading to potentially inaccurate estimates of the rate of real income growth. This paper calculates CPI bias for urban Indonesia by estimating food Engel curves for households with the same level of CPI-deflated incomes at four different points in time between 1993 and 2008. The results suggest that CPI bias was negative during the 1997–98 crisis but has been positive since 2000. From 1993 to 2008, CPI bias averaged 4% annually, equivalent to almost one-third of the measured inflation rate.     

Estimating International Adverse Selection in Annuities

Abstract

It is well known that purchasers of annuities have lower mortality than the general population. Less widely known is the quantitative extent of this adverse selection and how it varies across countries. This paper proposes and applies several methods for comparing alternative mortality tables and illustrates their impact on annuity valuation for men and women in the U.S. and the U.K. Our results indicate that the relatively lower mortality among older Americans who purchase annuities is equivalent to using a discount rate that is 50–100 basis points below the U.K. rate for compulsory annuitants or 10–20 basis points lower than the U.K. rate for voluntary annuitants. We then draw on the mortality experience of over half a billion lives to estimate mortality differentials due to varying degrees of adverse selection controlling for country, gender, and an allowance for mortality improvements. Results show that adverse selection associated with the purchase of individual annuities reduces mortality rates by at least 25% in the international context. We also find that the system of mortality tables used to value Japanese annuities is quite distinct from international norms.?     

The efficiency of sponsor and participant portfolio choices in 401(k) plans

To evaluate the extent of inefficient behavior in 401(k) pensions, now the dominant form of retirement saving in America, we attribute inefficiencies separately to the employer's menu design versus participant portfolio elections. Results from our analysis of over 1000 plans and a million participants demonstrate that most sponsors offer efficient investment menus, but participants undo this by constructing inefficient portfolios thus reducing their potential retirement wealth by one-fifth. Because participants are the main source of inefficient pension investment choices, strategies targeting their behavior may be useful — including improved default investment strategies or educational programs. We also show that the number of options offered is less important than the range of funds provided when designing 401(k) menus.     

Organizational achievement values,high‐involvement work practices,and business unit performance

This study examines the relationships among organizational achievement values, high‐involvement work practices (HIWP), and business unit performance. Specifically, we examine whether HIWP mediate or moderate the effect of achievement values on retail store performance. Using data collected at three points in time from more than 1,000 employees, we found support for the mediation model. The article concludes with directions for future research and implications for management practice. © 2011 Wiley Periodicals, Inc.     

Guaranteeing Defined Contribution Pensions: The Option to Buy Back a Defined Benefit Promise

After a long commitment to defined benefit (DB) pension plans for U.S. public sector employees, many state legislatures have introduced defined contribution (DC) plans for their public employees. In this process, investment risk that was previously borne by state DB plans has now devolved to employees covered by the new DC plans. In light of this trend, some states have introduced a guarantee mechanism to help protect DC plan participants. One such guarantee takes the form of an option permitting DC plan participants to buy back their DB benefit for a price. This article develops a theoretical framework to analyze the option design and illustrate how employee characteristics influence the option's cost. We illustrate the potential impact of a buy‐back option in a pension reform enacted recently by the State of Florida for its public employees. If employees were to exercise the buy‐back option optimally, the market value of this option could represent up to 100 percent of the DC contributions over their work life.
