The reform of invalid indicators of nuclear power impacts?

This article argues for more open acknowledgement of uncertainties surrounding the assessment of nuclear power impacts. It considers different cases where uncertainties have been of critical importance and draws attention to new ways of recognizing their nature. The idea is not to seek to ‘resolve’ uncertainty—an impossible goal given fundamental gaps and immaturities in the state of scientific knowledge on related matters—but to reveal its complexion, thereby providing for a more ‘truthful’ basis for planning and decision making.     

Reversal of fortune? The long-term effect of conservation-led displacement in Nepal

Building on a panel data-set using two rounds of self-administered surveys, this study assesses the long-term welfare effects of conservation-led displacement in Nepal. Empirical findings indicate that while displaced households suffered from poor land productivity and food insecurity in the first five years after displacement, they appear to be better off today, a decade since displacement, compared to non-displaced households. However, this has come at the expense of loosening social ties, increased strain on human capital and, most importantly, an overall deterioration in people’s socio-cultural wellbeing.

Is It Worth Getting Labeled? The Case of MSC-Certified Seafood

Research has examined consumers’ attitudes toward ecolabels, but there is a lack of research examining whether niche ecolabels give a competitive advantage in consumer markets. The authors aim to fill this gap by exploring the four conditions of market success (evidence of price premiums, market share, access to retailers, and elasticities) established in the literature. Three varieties of MSC-certified fish are studied. Differences are observed across the three varieties that lead to the following conclusions: MSC-labeled products do not systematically sell at a premium; price has an inelastic effect on the demand of certified national brands, but increased distribution has a very elastic effect on demand; and MSC-labeled products do not experience seasonal effects. The consumer market is responding favorably to the label, but ecolabeled fish is in an introductory stage. Price premiums vary; the retailer’s brand is playing a prominent role.     

The present and future use of ‘land’ below ground

The world's subsurface space, including Britain's, is already used in a variety of ways, ranging from occupancy to disposal and the bulk storage of materials and fuels. In the future it is likely that it will be put to further use in response to trends in technology, resource supply and demand, socioeconomics and geopolitics. Here the present and future uses of underground space, and the potential planning and social issues affecting its development, are reviewed. Future uses are likely to be in the area of increasing occupancy (both commercial and residential), the secure storage of documents and data, the storage of carbon dioxide for carbon abatement, natural gas, compressed air stores of energy from traditional and renewable sources, the use of underground heat in buildings and the proposed deep geological disposal of radioactive waste. The article will also explore pressure points and challenges. These will include the regulation of multiple uses of subsurface storage space and, for projects of national importance including natural gas and radioactive waste storage, legislation to lessen the effect of local opposition relative to the ‘national need’. This article does not discuss future mining, hydrocarbon extraction, or water resources.     

Do fertilizer subsidies crowd out organic manures? The case of Malawi

We assess the impacts of the Malawian Farm Input Subsidy Program on manure use at the farm plot level using more than 3,000 farm plot observations from six districts in central and southern Malawi over three years (2006, 2007, and 2009). The probabilities and intensities of manure use were investigated with the correlated random effects (CRE) probit and tobit models. The endogeneity of access to fertilizer subsidies and fertilizer use intensity was controlled for with a control function approach. Both the probability of manure use and intensity of manure use were positively correlated with the intensity of fertilizer use. A 1% increase in fertilizer use intensity is associated with a 1.94%–1.96% increase in the intensity of manure use outside the subsidy program and a 0.62%–1.66% increase in manure use with the subsidy program. A 1% increase in average fertilizer price was associated with a 0.43%–0.76% increase in the probability of manure use and a 3.5%–5.3% increase in the intensity of manure use.     

The Impact of Cosmetic Defects on Japanese Consumers’ Preference for Fresh Grapefruit

An online survey was conducted to investigate Japanese consumer preferences for fresh grapefruit based on prices and external fruit quality. The impact of 4 types of peel disorders (windscar, rust mite, melanose, and greasy spot) was investigated. Results from a discrete-choice model based on consumer responses indicate that willingness to pay for Extra Class fruit (no to little visible damage) is 1.5 times higher than the average willingness to pay for Class II fruit (highest level of visible damage allowed). Additionally, consumers revealed different utility levels depending on the type of peel disorder.     

Do the EU countries import at the same price? The case of coffee

The establishment of the Economic and Monetary Union was expected to determine price convergence in the market of the European Union, leading to the equilibrium theorized by the law of one price. This article investigates prices convergence in the coffee market among European importers. Coffee is not only a tradable and traded good, but also one of the most valuable traded commodities. We account for different qualities of coffee in a hedonic regression model, which isolate and remove the effects of factors that might affect price dispersion. Adjusted import prices result to be significantly different between European Member States, and do not support the hypothesis of a deepening European market integration.     

Safeguarding species richness vs. increasing the use of renewable energy—The effect of stump harvesting on two environmental goals

Deadwood is recognized as one of the most important resources affecting forest biodiversity. Its absence from the forest landscape is, therefore, of concern, such that one official Swedish environmental objective is to increase the volume of deadwood. However, increasing the use of renewable energy sources, another environmental goal, is likely to work against this biodiversity objective. In this study we utilize a regional economic forest sector model, focusing on northern Sweden, in order to estimate the effect of a large scale introduction of stump harvest on the future use of forest fuel. In addition, an ecological model, describing the relationship between the availability of stumps and the abundance of saproxylic beetles, is linked to the economic model.The parameters used in the economic model are derived from a data set spanning 28 years while the ecological model is derived from a survey of ten clear cuts, undertaken seven years after the clear cutting, in order to investigate the abundance of saproxylic beetles in stumps. We simulate the effects of an increased demand for wood fuels in northern Sweden, with or without stump harvest. The two scenarios have different effects on all major round wood markets in the region, as well as on the abundance of saproxylic beetles. More specifically, the harvest of stumps is associated with a 5% reduction in the mean abundance of saproxylic beetles living in deadwood on future clear cuts and a 3% increase in the use of renewable energy recourses in heating plants.     

Do farmer,household and farm characteristics influence the adoption of sustainable practices? The evidence from the Republic of Moldova

Drought represents the main constraint on agricultural production in the Republic of Moldova indicating the need to shift from conventional agricultural practices to more sustainable ones. To provide a more comprehensive understanding of the determinants and barriers influencing the adoption of conservation agriculture practices, an analytic framework combining both binary and ordered probit models addressing the potential endogeneity of variables was applied. A survey was conducted among 234 smallholders in three districts in the Republic of Moldova from July to September 2016. The results indicated that the adoption of sustainable practices by small-scale farmers is influenced predominantly by farmer characteristics and by their perception of risk. The findings of this research confirmed that households with lower access to financial resources are less likely to adopt these practices. Consequently, the provision of alternative financing is needed in the promotion of sustainable agriculture practices.     

The transformation of the Indian agricultural input industry: has it increased agricultural R&D?

Indian agricultural input industries have gone through a major transformation in the last 40 years. State owned firms grew during the Green Revolution and then stagnated or declined. Indian corporations that were protected from foreign competition are now exporters of agricultural tractors and pesticides. Foreign multinational corporations are rapidly increasing their role in the seed, pesticide, and tractor industries. Entry by large Indian firms and multinationals has increased competition in the input industries. Private agribusiness R&D in India grew from $23 million in 1985 to $250 million in 2009 in 2005 US dollars. This is the same time period as a transformation in the agricultural input industry, rapid growth in demand for agricultural inputs, breakthroughs in information technology and biotechnology, and changes in intellectual property rights. An econometric model was used to test whether the transformation of agricultural input industry was a major factor in the growth of R&D expenditure or not. This article analyzes a unique, firm level sales and R&D data set from the seed, pesticide, tractor, and fertilizer industries in 2000–2009. The estimated model indicates that agribusiness firms' R&D expenditures from 2000 to 2009 were positively related to variables associated with industry transformation such as firm size, ownership by multinationals, and declining industry concentration. The model also indicates that strengthening patent policy as well as growth in the size of research‐intensive industries like the seed industry contributed to the growth of agribusiness R&D in India.     

What's driving innovation in small businesses in Australia? The case of the food industry

There is strong evidence that innovation is a primary driver of a nation's economic growth. As Australia continues to compete in the global economy, it is imperative that businesses should be innovative to improve their performance. In this paper, we evaluate the status and main drivers of innovation in small businesses in the food sector in Australia. Discrete choice modelling and bootstrapping procedures are applied to a panel of firm‐level data collected through the ABS Business Characteristics Survey (2006–2007 to 2010–2011 for the Australian Bureau of Statistics’ Business Longitudinal Database Confidential Unit Record File) to investigate the factors affecting the likelihood of small food businesses to innovate. Results show that businesses are more likely to innovate if they collaborate, have higher information and communication technology intensity, and use science, technology, engineering and mathematics skills. We also found that small food businesses, even at the subsector level, do combine different types of innovation when innovating. The propensity to innovate also increases for small businesses that have flexible working arrangements, face moderate‐to‐strong market competition, operate overseas and seek finance through debt and equity. The relative importance of these factors was found to vary between agricultural and nonagricultural food subsectors.     

Physical infrastructure as a constraint on agricultural growth: The case of sub‐Saharan Africa

Abstract

The importance of agriculture in sub‐Saharan Africa, and the somewhat lagging development in other activities, suggests that particular significance attaches to the arrest of the drawn out crisis of agricultural production. Two opposing suggestions which are often made are that this is a matter either of price incentives, or of fundamental change designed to remove many infrastructural constraints and the lack of provision of other essential services. The issues are pursued, first, by an appraisal of the evidence relating to agricultural supply response. The long‐run response to price incentives is probably rather low, but it is suggested that it is very often constrained by non‐price factors. The paper then assesses the importance of infrastructural constraints, particularly in transport and communications. It is argued that the choices between improving price incentives and the need for infrastructure and other provision are not absolute since complementarities are important. Both, in effect, can also compete for public funds. The dilemma is particularly acute in sub‐Saharan Africa since low population densities and long distances result in the costs of transport and other essential services being comparatively high. It is therefore all the more necessary to seek cost‐effective ways of improving provision in order to maximize the impact on farm output. The paper suggests a number of ways in which this can be done, notably by better utilization of existing infrastructure.     

The End of a Romance? A Note on the Quantitative Impacts of a ‘Brexit’ from the EU

This study suggests UK equivalent variation (EV) gains of €8.9 billion on withdrawal from the EU budget. Factoring in associated trade facilitation costs from the loss of UK access to the single market, annual UK EV losses could be as high as €14.0 billion, with the EU‐28 facing a corresponding loss of €40.4 billion. Interestingly, the extrapolated UK gain arising from withdrawal from the ‘CAP’ component of the EU budget exceeds estimated lower and upper bound trade facilitation costs exclusively on EU agrofood trade. Accordingly, the UK should realistically remain as an EU member, although continue to lobby for reductions in the CAP budget.     

Is late really better than never? The farmer welfare effects of pineapple adoption in Ghana

Export agriculture offers potentially high returns to smallholder farmers in developing countries, but also carries substantial market risk. In this article we examine the intertemporal welfare impact of the timing of a farmer's entry into the export pineapple market in southern Ghana. We examine whether farmers who never cultivated pineapple are better or worse off than farmers who decided to adopt pineapple earlier or later relative to their peers and experienced a significant adverse market shock several years prior to our endline survey. We use a two‐stage least squares model to estimate the causal effect of duration of pineapple farming on farmer welfare. Consistent with economic theory, we find that earlier adoption of the new crop brings greater welfare gains than does later uptake. But we find that the gains to later uptake of pineapple—just before the market shock—are small in magnitude, just 0.1 standard deviations of a comprehensive asset index, indicating that the gains to adoption may be precarious and depend on the context, in particular on the severity of prospective market shocks.
