Human health and pesticide use in Sub‐Saharan Africa

While pesticides–such as insecticides, fungicides, and herbicides–are often promoted as inputs that increase agricultural productivity by limiting a range of pre‐harvest losses, their use may have negative human health and labor productivity implications. We explore the relationship between pesticide use and the value of crop output at the plot level and a range of human health outcomes at the household level using large‐scale, nationally representative panel survey data from four Sub‐Saharan African countries where more than 10% of main season cultivators use pesticides. We find that pesticide use is strongly correlated with increased value of harvest, but is also correlated with higher costs associated with human illness, including increased health expenditures and time lost from work due to sickness in the recent past. We take these results as suggestive that the findings of more targeted studies are indeed generalizable beyond their original, purposively chosen samples.     

The Effect of Using a Lattice Model to Estimate Reported Option Values

Statement of Financial Accounting Standards 123R suggests that lattice valuation models may improve the estimates of reported employee stock option values relative to the more commonly used Black–Scholes (BS) model. However, lattice model critics have expressed concerns that managers may use lattice models' flexibility to opportunistically understate option values. In this study, we investigate a sample of firms that recently adopted a lattice model to value employee stock options to provide evidence on this issue by identifying the determinants of lattice model adoption and examining the effect of lattice model use on reported option values. We report three main results. First, we find that firms are more likely to adopt a lattice model when it is more likely to produce lower values than the BS model and when managers have incentives to lower stock option expense. Second, we find that firms adopting a lattice model increase understatement of reported option values more than firms that continue to use the BS model and that the incremental understatement is due to use of the lattice model. Third, we conduct several tests to examine whether the valuation effect of lattice model use is consistent with efforts to correct for documented shortcomings in the BS model and find no evidence that this is the case. Taken together, the evidence in this study suggests that firms adopt and implement lattice models primarily to lower reported option values.     

Domesticating Gambling: Gender,Caring and the UK National Lottery

Abstract

The issue of gambling as a form of leisure practice has, to date, received very little attention from sociologists. This is despite the enormous range of consideration recently invested in gambling by policy makers, politicians, journalists, psychologists and economists. In particular, the role that gambling plays as an important part of women’s leisure patterns has been virtually ignored. In this paper, the impact of UK National Lottery play on women’s everyday leisure experiences is examined. A questionnaire was administered to a diverse group of 150 women, and 15 women from this sample volunteered to take part in in‐depth interviews. The questionnaires sought to produce a database of the frequency of lottery play, the types of games played and the amounts of money gambled. The interviews focused on individual experiences, meanings and perceptions of lottery play as a form of leisure. The quantitative and qualitative findings of the research are discussed in terms of the material and ideological constraints shaping women’s everyday experiences of leisure, and also in terms of the ways in which gender and ‘caring’ are reproduced through women’s National Lottery play. It examines the ways in which the lottery addresses a lack of time and space for women’s pursuit of leisure.     

The Efficiency of Categorical Discrimination in Insurance Markets

Crocker and Snow (1986) show that banning categorization based on risk‐related characteristics such as gender or race in pricing insurance policies is inefficient whenever categorization is costless. Their analysis, by contrast, suggests ambiguous welfare effects of banning costly categorization. I show that this latter conclusion is incorrect: categorical pricing bans are inefficient even when categorization is costly. Whenever the ban‐imposing government can instead provide breakeven partial social insurance, it can remove its ban in such a way that the insurance market will choose to employ the categorizing technology only when doing so is Pareto improving.

Perceptions of electricity-use communications: effects of information,format, and individual differences

Electricity bills could be an effective strategy for improving communications about consumers’ electricity use and promoting electricity savings. However, quantitative communications about electricity use may be difficult to understand, especially for consumers with low energy literacy. Here, we build on the health communication and graph comprehension literature to inform electricity bill design, with the goal of improving understanding, preferences for the presented communication, and intentions to save electricity. In a survey-based experiment, each participant saw a hypothetical electricity bill for a family with relatively high electricity use, covering information about (a) historical use, (b) comparisons to neighbors, and (c) historical use with appliance breakdown. Participants saw all information types in one of three formats including (a) tables, (b) bar graphs, and (c) icon graphs. We report on three main findings. First, consumers understood each type of electricity-use information the most when it was presented in a table, perhaps because tables facilitate simple point reading. Second, preferences and intentions to save electricity were the strongest for the historical use information, independent of format. Third, individuals with lower energy literacy understood all information less. We discuss implications for designing utility bills that are understandable, perceived as useful, and motivate consumers to save energy.     

MEDDLING IN OTHER MEN'S AFFAIRS: THE CASE FOR ANARCHY

This paper calls into question the foundational myth of political theory, the myth of the necessity of the state. The anarchic counterposition is briefly sketched before some central anti-anarchic arguments are considered and rejected.     

Redundancy and Early Retirement: The Interaction of Public and Private Policy in Britain, Germany and the USA

Labour force reductions have been a major issue in industrial relations in Western countries since the mid-1970s. Early retirement has enabled employers to structure these reductions better to suit their interests, and to reduce the damage to industrial peace which would otherwise occur. This paper looks at the role and nature of early retirement in cases of redundancy in three countries with different industrial relations and social insurance systems. Attention is given to how compensatory policies undermine protective policies; how the costs of early retirement are shared between the state and enterprises; the adequacy of early retirement benefits and their impact upon post-retirement income; and whether the state can be said to encourage early retirement.     

Liberalising the German model: institutional change,organisational restructuring and workplace effects

Institutional change at supranational, European Union level affects national and firm level institutions in various ways. This article traces effects of liberalisation measures in the airport industry enacted in two airport firms in Germany. The study, based on qualitative empirical research, found that EU liberalisation facilitated company creation of subsidiaries (subsidiarisation) and elevated shareholder interest in corporate governance. These factors affected institutional practices and cultural norms within the German industrial context that in turn influenced significant alterations in employment and workplace relations. Considerable disruption of the German social partnership model of corporate governance and industrial relations was observed. However, in addition to patterns of convergence towards neoliberal practices and outcomes frequently observed in Anglo‐Saxon systems, the study found some elements of effective retention of cultural institutional resources of the German model. Both ‘path departure’ and social embeddedness appear to coexist.
