O presente trabalho tem por objetivo utilizar a abordagem dos modelos lineares generalizados e os modelos de dispersão no contexto do seguro agrícola. Os modelos lineares generalizados (MLG's) constituem uma extensão dos modelos lineares de regressão múltipla introduzida por Nelder e Wedderburn (1972), que inclui modelos cuja variável resposta pertence à família exponencial de distribuições. O MLG é formado por um componente aleatório, que possui distribuição pertencente à família exponencial, um componente sistemático, conectados por uma função de ligação. Jorgensen (1997) estende a utilização dos MLG para uma classe mais ampla de modelos probabilísticos, denominados modelos de dispersão. A estimação dos parâmetros foi baseada no método da máxima verossimilhança, e também, em função da amostra ser relativamente pequena, optou-se pelo método de bootstrap não-paramétrico. As duas abordagens foram aplicadas a dois conjuntos de dados de sinistros de 15 municípios do estado do Rio Grande do Sul. Os resultados mostraram que a precipitação acumulada tem influência na ocorrência de sinistros. Entretanto, na modelagem do montante do sinistro não foi encontrada nenhuma variável significativa. Usando o método de bootstrap...

Designing and rating insurance products requires both science and judgment. In developing and emerging economies, actuarial procedures must be robust and implementable, as well as offering a sufficient degree of transparency and flexibility so as to allow expert judgment to be incorporated. This paper outlines an approach to designing and rating a portfolio of index insurance products that uses both temporal and spatial aspects of the data to increase the efficiency of statistical estimates. The approach has formed the basis for the design and ratemaking methodology implemented by the Agriculture Insurance Company of India for the modified National Agricultural Insurance Scheme, which was initiated by the Government of India in late 2010.

The authors identify the key issues and concerns that arise in the design and rating of crop yield insurance plans, with a particular emphasis on production risk modeling. The authors show how the availability of data shapes the insurance scheme and the ratemaking procedures. Relying on the U.S. experience and recent developments in statistics and econometrics, they review risk modeling concepts and provide technical guidelines in the development of crop insurance plans. Finally, they show how these risk modeling techniques can be extended to price risk in order to develop crop revenue insurance schemes.

Agricultural insurance is a tool to manage agricultural production risks and help producers reduce the effects of negative shocks and improve the allocation of resources. It provides a mechanism to transfer a variety of risks faced by crop, livestock, forestry, or aquaculture production. The small island nations of the Caribbean are highly exposed to tropical cyclones, hurricanes, and other weather hazards-and are particularly vulnerable to drastic losses from natural disasters. A single catastrophic event can affect a large proportion of clients, and this is often reflected in the insurance premiums charged by local insurance companies, especially if they only underwrite risk in one or a few neighboring islands (as is common in the Caribbean). To be able to pay many claims all at once, insurers must either purchase their own insurance (re-insurance), which is expensive, due to the high exposure to extreme weather events, or hold a large amount of cash reserves. The development of market-based agricultural insurance options in the Caribbean can range from regional and macro-level applications (sector...

Agriculture is a very important socioeconomic sector in Kazakhstan. The Government of the Republic of Kazakhstan (GRK) introduced a national compulsory crop insurance scheme in 2005 in order to provide grain producers and other farmers with a minimum level of protection against catastrophic climatic events. The overall objective of the current study is to assist the GRK in improving the existing mandatory crop insurance program. The study aims to identify sustainable market-based alternatives to the current crop insurance system in Kazakhstan. In this regard, all of the options for improving the current system that were developed under this study are market based and take into account global experience and the best insurance and reinsurance industry practices for agricultural insurance. The study follows the principles established in the agriculture risk management framework developed by the World Bank. The study focuses mainly on spring wheat crop production in the principal growing regions of Kazakhstan. The study is set out in six chapters. Chapter one gives introduction and objectives of the study. Chapter two presents an overview of agricultural production systems and markets in Kazakhstan...

Although there is fast-growing policy interest in offering financial products to help rural households manage risk, the literature is still scant as to which products are the most effective. This paper uses a randomized field experiment in Senegal and Burkina Faso to compare male and female farmers who are offered index-based agricultural insurance with those who are offered a variety of savings instruments. The paper finds that female farm managers were less likely to purchase agricultural insurance and more likely to invest in savings for emergencies, even controlling for access to informal insurance and differences in crop choice. It is hypothesized that this finding results from the fact that, although men and women are equally exposed to yield risk, women face additional sources of lifecycle risk -- particularly health risks associated with fertility and childcare -- that men do not. In essence, the basis risk associated with agricultural insurance products is higher for women. Purchasing insurance increased input spending and use more than savings. Those who purchased more insurance realized higher average yields and were better able to manage food insecurity and shocks. This finding suggests that gender differences in demand for financial products can have an impact on productivity...

Bangladesh is ranked as the world's fifth most exposed country to natural disasters, including floods, cyclones, and droughts. The purpose of this study is to investigate the viability of agricultural insurance in Bangladesh, particularly for small and marginal farmers and to present the Government of Bangladesh (GoB) with a set of options for the future development of agricultural insurance in the country. The current study aims to identify an overall framework for the development of sustainable market-based agricultural insurance in Bangladesh. It also reviews the technical, operational, financial, and institutional issues and options for the introduction of traditional crop and livestock insurance products and for new crop-index products that are suitable to Bangladeshi farmers. This report present a series of practical guidelines and options for GoB and other interested parties to consider for the future development and implementation of crop, livestock and aquaculture insurance in Bangladesh. This study benefits from this international experience (for example...

The broad structure of Modified National Agricultural Insurance Scheme (mNAIS), the main crop insurance program in India, is technically sound and appropriate in the context of India. The NAIS is based on an indexed approach, where average crop yield of an insurance unit, or IU, (i.e., block) is the index used. The insurance is mandatory for all farmers that borrow from financial institutions, though insurance cover is also available to non-borrowers. The actual yield of the insured crop (as measured by crop cutting experiments) in the IU is compared to the threshold yield. If the former is lower than the latter, all insured farmers in the IU are eligible for the same rate of indemnity payout. Individual crop insurance will have been prohibitively expensive, or even impossible, in a country such as India with so many small and marginal farms. Further, the method of using an 'area based approach' has several other merits and, most importantly, it mitigates moral hazard and adverse selection. This report offers detailed analysis of a number of technical and operational issues which should be addressed if mNAIS is to be implemented. GOI is to be complemented on its bold vision of the future of agriculture insurance through modifying NAIS...

Farming is a mainstay of the Kenyan economy, representing three quarters of employment in the country. Nearly half of all farming output in the country is for subsistence purposes. Therefore, many farmers livelihoods are entirely dependent on their harvests, both for the income generated by selling crops and for feeding their families. Unfortunately, there is little certainty in subsistence farming since the size of the harvest is largely determined by the timing and amount of rainfall. The objective of this case study is to describe the design and implementation of an index-based agricultural insurance product targeting rural farmers in Kenya. The Kilimo Salama (Safe Agriculture in Kiswahili) product has been successful in protecting farmers against risks from drought or excessive rainfall, both of which can have disastrous effects on the harvest. The following sections present weather-related risks affecting farmers, the steps taken to address these problems by designing a new insurance product, the product development and implementation process...

Governments in developing countries have been increasingly involved in the support of commercial agricultural (crop and livestock) insurance programs in recent years. A striking example is China, where, with support (and premium subsidies) from the central and provincial governments, the agricultural insurance market grew dramatically to become the second largest market in the world (after the United States) in 2008. In India and Mexico, weather-based crop insurance has been developed on a large scale to protect farmers against the vagaries of the weather. Many other countries have investigated the feasibility of agricultural insurance, and some have implemented pilot programs. This book aims to inform and update public and private decision makers involved in promoting agricultural insurance about recent developments in agriculture insurance. The literature is heavily biased toward the practice and experience of a few very large public-private programs in Northern America and Europe, which are driven by large public financial subsidies. This book provides decision makers with a framework for developing agricultural insurance. It is based on an analytical review of the rationale for public intervention in agricultural insurance and a detailed comparative analysis of crop and livestock insurance programs provided with and without government support in more than 65 developed and developing countries. The comparative analysis is based on a survey conducted by the World Bank's agricultural insurance team in 2008. Drawing on the survey results...
