Over the past dozen years, policymakers have largely abandonedlong-standing popular approaches for addressing risk in agriculturewithout fully resolving the question of how best to manage thenegative consequences of volatile agricultural markets. Thearticle reviews the transition from past policies and describescurrent approaches that distinguish between the trade-relatedfiscal consequences of commodity market volatility and the consequencesof price and production risks for vulnerable rural householdsand communities. Current policies rely more heavily on markets,even though markets for risk are incomplete in numerous ways.The benefits and limitations of market-based instruments areexamined in the context of risk management strategies, and innovativeapproaches to extend the reach of risk markets are discussed.   相似文献

This study attempts to measure with a two-region model some of the key economic relationships for Canadian wheat in the world market. The excess demand function facing Canadian wheat exports was found to be price elastic. Dynamic policy multipliers were derived to calculate the effects on wheat exports and the world price of changes in policy instruments including the initial payment for wheat.
Cette étude a pour but de mesurer, au moyen d'un modèle portant sur deux régions, quelques-uns des principaux rapports économiques entre l'économie canadienne du blé et les marchés mondiaux. La fonction de demande excédentaire des exportations canadiennes de blé s'est vérifiée élastique par rapport au prix. Les effets de changements dans les instruments de la politique agricole, tels que le paiement initial du blé, sur les exportation canadiennes et sur le prix mondial du ble ont eté calcule au moyen de multiplicateurs dynamiques.  相似文献

The Saskatchewan short-term hog loan program of 2002 provided a nonmarket credit-line to participating hog producers. The repayment conditions for cash advances committed to by the provincial government depend on later hog prices, and so the program has derivative contract attributes. We model the contracts and use an estimated spot price stochastic process to establish summary statistics for producer benefits from the program .
Le programme de prêt à court terme que la Saskatchewan a offert à ses producteurs de porcs en 2002 comprenait une ligne de crédit non marchande. Comme les modalités de remboursement des avances de fonds engagées par le gouvernement provincial dépendent du prix futur du porc, ce programme possède les caractéristiques d'un instrument dérivé. Nous avons modélisé les contrats et nous avons utilisé un processus stochastique pour estimer le prix au comptant en vue d'établir des statistiques sommaires sur les avantages que les producteurs retirent de ce programme.  相似文献

A key rationale offered by the Federal Reserve for the payment of interest on reserves was to remove the incentive for banks to operate sweep accounts. Sweeping shifts funds from transactions deposits subject to reserve requirements to non-reservable deposits. This paper extends a conventional banking model to analyze sweeping behavior. Sweeping responds positively to increases in bank loan rates and reserve ratios and negatively to increases in the interest rate on reserves or exogenous increases in bank equity. Sweeping generates greater responsiveness in lending to changes in loan rates or the interest rate on reserves and lower responsiveness to changes in reserve ratios or equity than in its absence. Empirical analysis of an explicit condition that we derive suggests that, with an unchanged reserve requirement, the Fed could eliminate sweeping by setting the interest rate on reserves to no less than approximately 4% points below the market loan rate.  相似文献

We show that small firms using syndicated loans for their mid- and long-term financial needs have significantly higher leverage than firms that do not borrow in this market. This difference cannot be attributed to firm characteristics like the availability of growth opportunities, asset tangibility, R&D spending, profitability and net sales that are known to influence capital structure. We also find that the capital structure of other firms that borrow in the syndicated loan market is not different from those that do not. We show that already highly leveraged small firms are more likely to borrow in the syndicated loan market than other firms. The higher debt in the capital structure of small firms that rely on syndicated loans consequently can be attributed to the availability of capital rather than demand for capital, as shown more generally by Faulkender and Petersen (Rev Financ Stud 19(1):45?C79, 2006).  相似文献

Intermediaries play a crucial role in the functioning of agricultural and food markets in developing countries through linking production, imports and storage with consumption. We analyse how competition in the intermediary sector and alternative forms of intermediaries determine the incentives for storage and market outcomes more generally. We apply this framework to the Egyptian wheat sector as an illustrative case study, a country where food security is a priority, where both forms of intermediaries co-exist and undertake storage but where issues of reforms to the role of intermediaries have been raised. Through stochastic simulation, we analyse two changes in government policy: first, the effects of changing the policy instruments with both types of intermediaries undertaking storage; second, relating to market reforms where the private sector replaces the storage function of the parastatal. These issues have wider significance for addressing the interaction between food security and a wide range of policy reforms including de-regulation of parastatals in developing countries.  相似文献

This article investigates the consumption patterns of black Americans for five different commodity groups: food, housing, clothing, health care, and transportation. The black consumer’s demand for these products is hypothesized as describable by the linear expenditure system. The system allows the investigation of changing relative commodity prices and income. The system also establishes a basic consumption bundle as an estimable parameter of the system. The basic bundle allows for changes in composition due to increased product familiarity, habit formation, and emulation by black consumers. Product familiarity and habit-formation play a role in determining the black consumer’s demand for the commodities food, housing, and clothing. This demand is also partially determined by the consumer’s “emulation” of consumption standards established by society in general. The article is not a comparison study of black-white differences in consumer behavior; however, the possible existence of an emulation effect in black consumer behavior suggests an interrelation of black-white consumer welfare which might fruitfully be studied by future researchers.  相似文献

Despite the intensifying debate over the taxation of Internet commerce, the relevant issues have not been given a systematic treatment in the context of the literature on optimal taxation. This article presents such an analysis and investigates separately the taxation of business purchases of intermediate goods, the taxation of consumer purchases of final goods and services, and the various issues of administration and compliance costs as they apply to the development of E-commerce. The authors conclude that generally the optimal tax literature cannot be used in support of a blanket tax exemption for Internet purchases. Certain conditions could lead to the optimality of an exemption, but those conditions are not likely to be met in practice.  相似文献

We use contingency theory to examine, for the first time, the incidence and effectiveness of CEO/COO duos. We argue that industry dynamism, extraordinary organizational task demands, and the CEO's own professional limitations will influence the decision to have a COO, as well as its effect on performance. Based on a large 10‐year sample, we find some support for the contingency view in explaining the presence of COOs; we particularly find that CEOs who lack experience in operational activities and in managing the focal firm are relatively likely to have COOs. We find, however, essentially no support for the contingency view in explaining when COOs are most beneficial. Instead, we find strong evidence of a very substantial negative main effect: CEOs who have COOs deliver lower organizational performance than those who do not.
