A number of studies have been conducted to determine the extent to which large firms utilize sophisticated techniques in capital expenditure decision making. This research effort focuses on financial decision making procedures of small firms, exploring the techniques utilized to evaluate investment opportunities, methods employed to adjust for risk, purposes of expenditures and concern for profitability, and the source and cost of funds. In light of the recent debate on the capital shortage issue, small firms were also asked what type of tax reform they deemed most desirable to stimulate capital investments.  相似文献

Vector autoregression (VAR) methods are used to analyse the contribution of supply, demand and policy shocks to unpredictable fluctuations in the market for Australian wool. VAR procedures are compared with conventional structural econometric models as methods for decomposing sources of instability. While each has advantages and disadvantages, VAR procedures might be viewed as preferable when the underlying market structure is complex and uncertain, as it is in the case of wool. Based on the results obtained, demand shocks are the dominant source of uncertainty in the wool market in the absence of Australian Wool Corporation intervention, but intervention has blunted their effects, reducing market uncertainty and increasing the average level of prices and revenues.  相似文献

The common presumption that food-importing developing countries would be harmed by a liberalization of world food trade is questioned in this paper. Both theory and new empirical modelling evidence suggest the possibility of the opposite conclusion. Even if just advanced industrial countries were to liberalize their food trade, the present empirical analysis (using a model of world food markets) suggests that economic welfare and net foreign exchange earnings from food trade could improve for the vast majority of developing countries. The extent to which that gain would be greater if developing countries also were to liberalize their policies affecting food markets is shown as well. The analysis helps to reconcile differences between previous results using partial-equilibrium models and those derived from computable general equilibrium models.  相似文献

The North American Waterfowl Management Plan seeks to improve wildlife habitat and increase waterfowl numbers through voluntary transactions with farmers to modify their land management practices. The impact of modified land use practices on the incomes of participating farmers and the regional economy are estimated. The compensation offered under the Plan for modification of land use is determined to adequately offset any loss in participants' income. Income losses to the community due to reduced farm input sales were more than offset by the increase in NAWMP direct expenditures (excluding compensation payments). Distributional effects and externalities must be recognized and monitored to ensure success of the program  相似文献

I study a horizontal differentiation model in which one of two attributes of a product, product fit and price, is more salient for a consumer than the other and different consumers can find a different attribute salient. The attribute that is more salient is determined by relative differences between the two products and is determined endogenously as a result of firms' pricing strategies. High (low) marginal costs soften (toughen) price competition between firms. Pass-through rates are greater than 1 for some parameter values. Both industry- and firm-level cost increases may be beneficial for firms.  相似文献
