This article analyses the effects of action aimed at narrowing the gap between South Africa's ‘two agricultures’, specifically the effects of the Farmer Support Programme (FSP) on structural aspects of maize production under different marketing policies. This is done by assembling a sectoral linear programming model of the South African summer-rainfall grain-producing area. The emphasis is on the inclusion of supply, demand and production risk. Results show that the effects of a successful FSP on specific interest groups, e.g. consumers of a specific product, or producers in a specific region, depend on the marketing policy followed, as well as on the effectiveness of the FSP. The analysis accentuates the interrelationships in South African crop production and illustrates how past policies ignored regional comparative advantages, distorted regional development and affected social welfare.  相似文献

This paper reviews the measurement of equilibrium unemployment in Australia using the Phillips curve. To provide a theoretical framework through which these measurement exercises can be understood, the theory of equilibrium unemployment based on wage bargaining is also described and reviewed. The paper shows how studies have moved from specifying a unique and constant equilibrium rate of unemployment to specifications which emphasise the influence of unemployment benefits, hysteresis and a range of equilibrium rates of unemployment.  相似文献

Economic policy is commonly treated as a vehicle for selecting among possible allocative outcomes within an economy. An economy, however, is a complex network of relationships whose patterns can be understood but whose details can be neither predicted nor controlled. Because of this complexity, allocative outcomes are not direct objects of choice. They are simply emergent consequences of human interaction that takes place within some framework of governing rules and conventions. All economic policy can do is modify some of the rules that govern this interaction. Economic policy is thus constitutive and not allocative in character, being centrally involved in shaping the character of the regime that governs our relationships with each other.  相似文献

At some stage in every household's family life cycle, the household is likely to make certain decisions with regard to its housing environment. Although the household's housing decisions essentially comprise the decision to move, and the selection of a new residence, the process from which these decisions are derived is very complex because varying circumstances could produce a multitude of different housing decisions. Due to the sheer complexity of the household's housing decision–making process, researchers have generally focused on individual decision–making stages rather than on the process as a whole. This paper therefore attempts to conceptualize the entire household housing decision–making process using theoretical concepts from the economic perspective, and then tests the conceptual model with empirical evidence drawn from the moving population within the multi–racial society in Singapore.  相似文献

The dominant form of equity pay in the U.S. will change dramatically when accounting rules are changed (most likely in 2005) to require companies to charge the cost of their stock option plans on their income statements. Many companies are already switching from stock options to other forms of equity pay, especially restricted stock. The most notable switcher was Microsoft, the world's largest user of stock option pay. In July 2003, partnering with J.P. Morgan, Microsoft created a onetime transferable stock option (TSO) program that allowed holders of underwater Microsoft options to sell their options to J.P. Morgan in return for restricted shares.
But the most important consequence of this transaction may not be a widespread shift by corporate America to restricted shares, but rather the creation of a more costeffective kind of stock option. By clearing the potentially messy hurdles involving taxes, accounting, SEC rules, and "transaction mechanics," Microsoft has opened the door for TSOs to be considered as an ongoing equitypay instrument, perhaps replacing standard stock options (which are not transferable). TSOs share the key advantages of restricted stock in terms of providing robust retention and ownership incentives and higher valuecost efficiency, while maintaining the key "leverage" advantage of options. In so doing, they create significant upside (and downside) while largely avoiding the "pay for pulse" problem of restricted stock. They also introduce the discipline of competitive pricing by third-party bidders. The bid prices of investment banks create nearly all of the information required for accurate estimates of option cost, which should foster greater board accountability and improved corporate governance.  相似文献
