A retail market in which customers repeat purchase is modelled. When customer movement between firms is sluggish, price overshooting characterizes firms' optimal response to demand or cost shocks. Thus retail prices would be predicted to be more variable than wholesale prices, a prediction at variance with empirical evidence. Uncertainty in demand and customer imperfect information are introduced into the model to attempt to reconcile this inconsistency between theory and evidence. The introduction of demand uncertainty actually increases the magnitude of price overshooting. By contrast, the introduction of imperfect customer information reduces the variability in retail prices. 相似文献

A model of food provision through growing, hunting or raising food was developed. Food supply was less of a problem for those who grew, raised or hunted their food than for others. Non-market food provision was a viable alternative for consumers regardless of educational levels, income levels and employment status. Home food production varied by other characteristics. There was not a significant difference between urban and rural households in some types of food provided. Results of this study can be helpful to professionals assisting households with resource use and to policy makers concerning policies to assist low-income consumers. 相似文献

Most EU-15 countries have kept restrictions to migration from the new member countries but committed to removing them within seven years from the 2004 enlargement. This article predicts the sectoral trade and real wage impact on high-income, mid-income, and low-income members of removing those restrictions, given two extreme scenarios: either all migrants are skilled or all are unskilled. The main effect of skilled migration is the relocation of high-scale economy, skill-intensive industries from mid-income into high-income countries. The main effect of unskilled migration is the relocation of low-scale economy, low skill-intensive industries from low-income into mid-income countries. Both high-income and low-income members would be better off with skilled migration, but those with mid-income would benefit from unskilled migration. ( JEL F1, F15, F22, J31, L6) 相似文献

Despite theoretical arguments matching type of diversification strategy with mode of entry, the exact form of relationships between strategy, mode of entry, and performance remains enigmatic. Our analysis, based on two samples, demonstrates that matches between strategy and mode did improve performance in one time period, but not a second. In addition, the results show that exclusive reliance on a single mode (internal development or acquisition) can restrict performance. © 1997 by John Wiley & Sons, Ltd. 相似文献
