To protect farmers from health care costs and risks to livelihood, most countries have developed special health and social insurance programmes specifically for farmers. While numerous studies have examined the determinants of participation in these programmes, little is known about how they influence famers' land and labour allocations. Without government‐sponsored health and social insurance, farmers may seek off‐farm employment in order to obtain similar benefits. Conditioning eligibility for social insurance on minimum land holdings and on‐farm work days can lead to delayed retirement and other forms of job lock. We investigate these issues using a unique dataset of 703,287 farms in Taiwan. After controlling for non‐random participation in Taiwan's social insurance programme, we find that the programme increases (decreases) on (off) farm labour supply, and decreases the amount of set‐aside land. This suggests that payments from social insurance substitute for those issued through land set‐aside programmes to some extent, and that failing to account for this substitution increases the cost of achieving both programmes' objectives.  相似文献

After 2008, China dairy industry has experienced a consolidation supported by the government mainly for the reason of food safety. Subsidies are one of the tools to shape a concentrated market with goals of reducing regulation cost and accomplishing quality control. This gives a serious concern that subsidies would generate a less competitive dairy industry. We construct a parametric model and use the firm‐level panel data, specifically the top eight dairy firms, to test if government subsidies strengthen the market power in the dairy industry. Our empirical results indicate government subsidies have a negative impact on the Lerner index for the top privately owned firms, but no significant effect on state‐controlled ones after controlling for advertising, time trend, and proprietorship. It is possible that the subsidies give more room for private firms to increase the scale or suppress the price, which eventually reduces the market power and benefits dairy customers in the downstream.  相似文献

Genuine savings is a conceptually valid one‐sided indicator as to whether Australia is on a weak sustainability path (negative GS would warn that current welfare is unsustainable). The World Bank's adjusted net savings (ANS) data summarise the available evidence, and by this indicator Australia is muddling along, at best. ANS misses some important pieces of the picture – net depletion of water, soil and biodiversity, and most kinds of pollution damage – and thus overstates Australia's genuine savings performance. Weak sustainability can be promoted by getting the prices right, and piecemeal efforts are underway via regulatory approaches and resource/environmental markets of various kinds. Nevertheless, particular resource problems – habitat conservation, biodiversity, climate change and dryland salinity – are likely to also require strong sustainability approaches. A sustainable future involves pushing weak sustainability as far as the body politic permits, invoking precautionary instruments for specific resource crises, and nurturing policy processes that encourage the consensus‐building that will be necessary to get it done.  相似文献

Using China Family Panel Studies (CFPS), this study investigates factors associated with the choice of farmland leasing strategies and the impact of leasing options on farm performance. Particular attention is given to off‐farm employment and farm subsidies. Additionally, the study applies a selectivity‐based approach to assess the relationship between farmland leasing choices and farm businesses’ performance. Off‐farm employment, older and educated operators, large farms and old‐age pension plans increase the likelihood of leasing out farmland. Part‐time off‐farm employment, grain subsidies and mechanised farms increase the likelihood of leasing in farmland. Finally, the selectivity correction terms in the value of crop production are significantly negative in the choices of farmland leasing, indicating the presence of sample selection effects. Accounting for selectivity is essential to ensure unbiased and consistent estimates.  相似文献

All over the world spatial flood risk management policies are on the rise. This paper analyses the planning process for the Overdiepse polder, a so-called “Room for the River” project in the Netherlands. After high water in the 1990s, the Dutch government changed its flood risk management policy. While before 2000 it leaned heavily on dikes to separate water from land, after that year spatial measures to “let the water flow” were introduced. This required the integration of two formerly separated policy domains: flood risk management and land use planning. In the densely populated and economically highly developed Netherlands, returning space to the river unavoidably impacts on the lives and livelihoods of those who live and work along the rivers. Therefore, such spatial measures to decrease flood risk have to be negotiated with various stakeholders. The planning process towards making the Overdiepse polder suitable for temporary water storage deserves more in-depth analysis. We describe and analyze the development of relationships between key actors in the planning process, with a focus on planning practices rather than on assumptions about the existence of certain types and qualities of relationships. We conclude, among others, that citizen involvement can, under specific socio-political and institutional conditions, build trust among stakeholders and increase local legitimacy for interventions by government agencies. However, it should not be idealized as “self-governance” or assumed to be part of a unidirectional change in water interventions towards new relationships between actors.  相似文献

The paper considers the role that the international human rights framework should play in the extension and application of Sen's capability approach. It discusses how emerging international standards in the field of human rights, supported by international human rights law, provide a basis for the specification and justification of lists of central and basic capabilities, and associated lists of duties on governments, international organizations and other international obligation-holders (both at the individual level, and collectively—through international co-operation). The idea of combining the capability framework with a background or supplementary theory of international obligation in the field of human rights is examined in the light of broader theoretical debates about the extension and application of the capability approach. The notion of a “human rights-based capability list” is then introduced. Finally, the paper suggests some possible applications of “human rights-based capability lists” in human rights advocacy and international poverty analysis.  相似文献

Integrated pest management (IPM) potentially reduces pesticide use and costs of agricultural production. However, IPM is knowledge intensive and its spread may dissipate over time due to knowledge required for its effective implementation and to competing messages about pest control. We examine IPM spread and adoption several years after formal intensive IPM outreach efforts ceased in a potato‐producing region in Ecuador. We describe adoption patterns and sources of IPM knowledge in 2012 and compare them with patterns that existed when outreach ceased in 2003. Results show that IPM adoption continues in the area but with a lower proportion of farmers fully adopting all practices and a higher proportion adopting low to moderate levels as compared to 2003. Almost all potato farmers in the area use some IPM practices, reflecting a major increase in IPM use. Farmer‐to‐farmer spread has supplanted formal training and outreach mechanisms. IPM adoption significantly lowers pesticide use and saves production costs for adopters.  相似文献

Agricultural biotechnology (genetic modification) has encountered resistance from many consumers, resulting in disparate regulatory approaches across different jurisdictions. The recent advent of CRISPR-Cas9, or gene editing, offers the potential for significant improvements in plant breeding. However, little is known currently about consumer responses to the technology. A factor often omitted from previous economic analyses of consumer acceptance of new food technologies is underlying human values or worldviews. Drawing upon cultural cognition theory and using data from a survey of Canadian consumers, we examine the influence of cultural values on food choice behaviours. Respondents’ pre-existing cultural values are measured on two dimensions: hierarchy-egalitarianism and individualism-communitarianism. Choice behaviours are captured using a discrete choice experiment featuring a sliced apple product with two consumer-oriented attributes (non-browning and antioxidant-enhanced) and three novel food technologies (gene editing, genetic modification, edible coating). Using a random parameters logit model with error components we find pre-existing cultural values to be significant determinants of choice behaviours. Individuals pre-disposed towards a hierarchical worldview are more accepting of novel food technologies, as are individuals with a communitarian worldview. While the use of gene editing results in negative marginal utilities in a food choice situation, the effect is not as large as with genetic modification, suggesting there is scope to ameliorate potentially negative reactions to the technology with value-compatible messages.  相似文献

This article investigates differences in household production and consumption among small‐ and large‐scale irrigators to assess whether the scale of an irrigation project increases household welfare in Mali. Much of the evidence of the impact of irrigation does not use counterfactual analysis to estimate such impact or distinguish between the scale of the irrigation projects to be evaluated. In the dataset collected by the author, both a large‐scale irrigation project and small‐scale projects are used to construct counterfactual groups. Propensity score matching is used to estimate the average treatment effect on the treated for small and large irrigators relative to non‐irrigators on agricultural production, agricultural income and consumption per capita. Small‐scale irrigation has a larger effect on agricultural production and agricultural income than large‐scale irrigation, but large‐scale irrigation has a larger effect on consumption per capita. This suggests that market integration and non‐farm externalities are important in realising gains in agricultural surplus from irrigation.  相似文献

Cropland abandonment occurring both nationally and globally threatens food security and environmental sustainability. We explore whether agricultural cooperatives help reduce cropland abandonment, using data collected from 5,593 households in 229 villages in China. By estimating a two-stage residual inclusion approach, we provide evidence that the existence of agricultural cooperatives in rural villages reduces the probability of cropland abandonment and the abandonment ratio. Further analysis shows that cooperative effects on cropland abandonment and the abandonment ratio are heterogeneous across geographic locations.  相似文献

In the last 40 years, Tunisia has experienced—as many other developing and emerging countries—a dietary transition, which led to an increase in the consumption of sugar, fats, and animal products. This transition was accompanied by an increase in noncommunicable diseases, particularly cardiovascular diseases. Using mathematical programming, we optimized the Tunisian diet using the French dietary recommendations as constraints. Then, we used the Global Trade Analysis Project's constant elasticities of substitution in order to simulate the impact of fulfilling the nutrient recommendations on international trade and domestic supply. Using this approach, we showed that the Tunisian diet is rich in carbohydrates and sugar but lacks fibers, some minerals, and vitamins. The adherence to all recommendations would induce an imperative shift to less sugar and cereal-based products by reducing the import dependence on these products, but would result a dramatic increase in the domestic supply of products from animal origin, fruits, vegetables, and legumes.  相似文献

This article is devoted to common yet quite specific approaches to valuation practice tasks that are involved in determining the market value of real properties in areas of possible land use changes. An intrinsic element of market value in such areas is the hope value, for which an option pricing model is used quite frequently.The authors propose a specially adapted Samuelson-McKean model for this task, which allows market value indication to be determined not only with the built-in development option, but also the dynamics of its components value in the current highest and best use and hope value – depending on the location of the given property. The greatest advantage of the Samuelson-McKean model is that it can be treated as universal for analyzing the range of possible indications of market value seeing as how its main task is to find a compromise between the interests of the buyer and the seller, which is the goal of any fair transactions and decisions.  相似文献

We analyse the growth of family farms in Israeli cooperative villages during a period of economic turmoil. We use instrumental variables to account for the endogeneity of initial farm size, and correct for selectivity as a result of farm survival. We also include a technical efficiency index, derived from the estimation of a stochastic frontier production model, as an explanatory variable. Our aim is to check whether ignoring efficiency could have been the reason for convergence results obtained elsewhere in the literature. We found that technical efficiency is an important determinant of farm growth, and that not controlling for technical efficiency could seriously bias the results. In particular, larger farms are found to grow faster over time, while without controlling for technical efficiency the farm growth process seemed to be independent of initial farm size. The increasing polarisation of farm sizes in Israel has ramifications for the inefficiencies induced by the historical quota system, for the political power of the farm sector and for the social stability of farm communities.  相似文献

This study revisits the issue of mean reversion in the import rice prices of six Asian countries over the period between 1995 and 2015. Augmented Dickey Fuller tests with a conventional linear regression model support the presence of a unit root in the levels of the price data. However, when regressions allow for Markov switching in coefficients and variances to capture periodic shifts in levels and volatilities, there is strong evidence against the unit‐root null hypothesis in favor of stationarity over much of the observation period.  相似文献

Although meat demand is one of the most studied issues in agricultural economics, our understanding of this phenomenon has been hampered by valid concerns about model specification uncertainty. This article revisits the need for more general theories of aggregate U.S. meat demand. Using a Bayesian averaging of classical estimates approach, we draw comprehensive inferences over 1,048,576 demand systems. We find very little evidence supporting the need for more general theories that include demand determinants beyond prices and expenditures. We find strong evidence in support of symmetry and negativity, but strong evidence against homogeneity, which is consistent with other research.  相似文献

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.  相似文献

Are commercial real estate prices in metropolitan New York affected by the type or nationality of the investors involved in a transaction? Previous research has highlighted differences in pricing between in-state and out-of-state investors and between different types of investors, but there are few extant studies that consider the influence of nationality on pricing at a micro-level. Foreign investors might pay more than domestic investors for commercial real estate assets because of a lack of information or experience in the market concerned. However, they might use local partners or brokers to mitigate such problems. To explore these issues, we use data provided by Real Capital Analytics on over 3000 office transactions in the New York metro area from 2001 to 2015. We use hedonic regression techniques and propensity score matching to examine whether pricing differs across investor groups after controlling for asset attributes. We find that foreign investors pay more than domestic investors at acquisition, but receive more when selling assets. Tests suggest that it is unmeasured aspects of quality that explain any apparent overpayment for offices in this location, not information issues.  相似文献

Based on government statistics and interviews with villagers across Malawi this article argues that customary matrilineal and patrilineal land tenure systems serve to weaken security of land tenure for some family members as well as obstructing the creation of gender-neutral inheritance of lands. Data from the National Census of Agriculture and Livestock 2007and the 2008 Population and Housing Census are used to characterize marriage systems and landholding patterns of local communities. Marriage systems correspond to customary land-tenure patterns of matrilineal or patrilineal cultures. The differences between the two ways of land holding represent a challenge for land reforms aimed at unifying rules for land tenure and land devolution. Drawing on an analogy of the resilience of the patrilineal land holding system in Norway, we argue that it will be difficult to remove the preferential rights of lineage members directly. We recommend that, instead of creating a unified national system, existing land rights should be formally recognized and circumscribed by fair procedures. A well-designed landholding system should aim to ease the transitions of diverse customary tenure systems towards the requirements of a modern large-scale society.  相似文献
