This paper investigates a central part of the argument that agricultural assistance by the United States to developing nations leads to diminished export markets for U.S. farmers. A sizeable cross section of low-income and lower-middle-income nations is used to provide statistical analyses of: (1) the link between agricultural productivity and economic performance, and (2) the link between economic performance and agricultural imports. The results show that a reasonably strong case can be made for the idea that advances in agricultural productivity are associated with long-run increases in imports of cereals and other agricultural products by less wealthy nations. The connection comes via the positive income effect of general economic development. For these countries, investments in agricultural development through successful assistance are not detrimental to U.S. farm export interests in the long run. They are generally beneficial. For middle-income nations, the case is less clear and more controversial. However, nothing in the cross-section data used suggests that farm productivity improvements in these nations is systematically threatening to U.S. agricultural trade in the long run.  相似文献

In order for farmers to accept improved soil and water management practices, new technologies must be appropriate to the specific site conditions found in the farm setting and be consistent with farmers' objectives and available resources. A whole-farm modeling analysis of this problem is described. Preliminary estimates of the benefits of increased soil moisture conservation for representative low-resource farmers in Mali are presented. If farmers could improve rainfall infiltration from currently low rates of about 40% up to 60%, and use small amounts of chemical fertilizers, disposable income could increase two to four times depending on rainfall. Income could be increased another 50% if the infiltration rate was raised to 80%. Food grain production could increase 60 to 90% with improved moisture conservation and fertilizer use.  相似文献

We analyze the role of firm‐level corporate governance in determining the precommitment payout policy of emerging market firms and investigate whether there is a precommitment life‐cycle effect. Unlike previous studies of U.S. firms, we find evidence of precommitment only among relatively well‐governed firms, which combine good governance with large dividend payouts to shareholders and large debt‐related repayments to creditors. We also document a strong precommitment life‐cycle effect. Firms in the growth and mature stages of their life cycle tend to use both debt and dividends to precommit to investors, with an increasing proportion of dividends in total payout measures. Our results are robust to an array of control variables, alternate payout proxies, market setting, and firm‐level corporate governance, and it addresses potential endogeneity concerns in the sample.  相似文献

This paper reports the results of a scientific survey of the equity valuation practices of CFA Institute members with equity analysis job responsibilities. Using an instrument designed to minimize biases in prior valuation surveys and sampling a larger group than in previous studies (13,500 investment professionals, resulting in 1,980 valid completed questionnaires), this paper documents professional practices in the selection of equity valuation approaches, including specific model variations and key input preferences. Important differences in practice were observed across geographies and employer firm types.  相似文献

As developing countries search for ways to promote capital formation through the establishment of organized exchanges, they will need to pay more attention to the role of risk management in the securities settlement process. The delivery-versus-payment (DVP) agents that facilitate the process of exchanging securities for funds in most world markets have both the incentive and comparative informational advantage to monitor, measure, and manage risks inherent in the securities settlement system.
Unfortunately, most DVP agents have accomplished this task to date through the cumbersome use of position and net debit limits, capital requirements, and collateral requirements. Such limits and requirements are almost everywhere based on relatively arbitrary criteria that may have no relation to the actual replacement cost, principal, or liquidity risk of the transaction, portfolio, or participant on which they are imposed.
To remedy this shortcoming in the current state of risk management at DVP agents, this article holds out the possibility of integrated, comprehensive risk management processes that emphasize and rely on forward-looking measures of risk for individual brokers and across brokers. Many risk measures could serve the settlement agent's purposes, including "value at risk" (or "VaR"), "below target risk,""below-target probability," and "downside semi-variance." The actual summary risk measure used for risk monitoring and control is not as important as the methodology used to generate that risk measure. "The goal of such a process," as the authors put it, "is to ensure that the risks to which a settlement agent and its residual claimants are exposed are those risks to which the agent's shareholders think they are and want to be exposed."  相似文献
