Increasing demand for cereals produced from limited natural resources stimulated the Green Revolution in grain crops like wheat and rice. But the gap between potential and actual production continues. Concerns about sustainability, and the social and technical shortcomings of the Green Revolution, have triggered a number of alternative crop production strategies. One, in particular, the so-called System of Rice Intensification (SRI), is attracting attention by governments, civil society organizations and farmers in Asia and elsewhere. 相似文献

This paper asks whether rating agencies played a passive role or were an active driving force during Europe??s sovereign debt crisis. We address this by estimating relationships between sovereign debt ratings and macroeconomic and structural variables. We then use these equations to decompose actual ratings into systematic and arbitrary components that are not explained by previously observed procedures of rating agencies. Finally, we check whether systematic, as well as arbitrary, parts of credit ratings affect credit spreads. We find that both do affect credit spreads, which opens the possibility that arbitrary rating downgrades trigger processes of self-fulfilling prophecies that may drive even relatively healthy countries towards default. 相似文献

The origin of the world credit crisis has four stages: (1) too much credit – an international perspective; (2) too much risk – reaction to low real interest rate; (3) the fatal flaw – the new complex financial instruments; and (4) the panic – bank lending dries up. The paper also discusses how the crisis spread around the world from the US, whether the high credit expansion was the fault of Alan Greenspan, whether China is to blame, and how this crisis related to the often expected crisis of global imbalances. Some implications for long‐term reform are discussed. 相似文献

Abstract In this paper asymptotic properties for the risk process will be studied when the number of risk units tends to infinity. The paper extends asymptotic properties for the classical risk process to more general processes. In the classical risk process the claim amounts are assumed independent and identically distributed, and the claim number process is a homogeneous Poisson process. The key tool is point process theory with associated martingale theory. The results are illustrated by examples. 相似文献

Using data from the UK Census of Production, including foreign ownership data, and information from UK industry input-output tables, this paper examines whether the intensity of transactions linkages between foreign and domestic firms affects productivity growth in domestic manufacturing industries. The implications of the findings for policies promoting linkages between multinational and domestic firms in the UK economy are outlined. 相似文献
