The sealed bidk-double auction is a mechanism used to structure bilateral bargaining under two-sided incomplete information. This mechanism is tested in two experiments in which subjects are asked to bargain repeatedly for 50 rounds with the same partner under conditions of information disparity favoring either the buyer (Condition BA) or seller (Condition SA). Qualitatively, the observed bid and offer functions are in agreement with the Bayesian linear equilibrium solution (LES) constructed by Chatterjee and Samuelson (1983). A trader favored by the information disparity, whether buyer or seller, receives a larger share of the realized gain from trade than the other trader. Comparison with previous results reported by Daniel, Seale, and Rapoport (1998), who used randomly matched rather than fixed pairs, shows that when reputation effects are present this advantage is significantly enhanced. A reinforcement-based learning model captures the major features of the offer and bid functions, accounting for most of the variability in the round-to-round individual decisions. 相似文献

Two “laws” are used to describe the budget shares of staple food, other food, and non-food in 28 regions in China: Working's model, which describes the budget share of (total) food as a declining linear function of the logarithm of total consumption expenditure, and a second model that describes the ratio of the budget shares of staple and other food as a double-log function of total consumption expenditure. Staple food appears to be an inferior good in the richest regions but not in the other regions. 相似文献

Food security concern in China is also the world’s concern. Studies on food consumption in the past, however, often neglected the increasing food consumed away from home (FAFH). Drawn on a survey data recently conducted in nine cities by a week-long diary method, we found that FAFH in urban China accounts for a significant proportion of total food consumption, although its share varies by food category. With substantial expected income growth, overall FAFH consumption will likely continue to rise, but would be negatively affected by the rapid societal aging process, both in dining out probability and per capita consumption level. The main findings of this study have implications for food processing and service industries as well as for studies in food-related environmental issues. 相似文献

MODELING INTERNATIONAL CONSUMPTION PATTERNS 总被引:1,自引:0,他引:1
This article addresses a number of key problems commonly confronted in the literature on international demand analysis. These include data issues and requirements, multistage budgeting, outliers, group heteroskedasticity, and model selection. A two-stage demand system is fit to International Comparison Programme data for 114 countries for nine aggregate categories and eight food sub-categories of goods. Outliers are identified and omitted from the sample. Parameter estimates for the two stages are obtained with a maximum-likelihood procedure that corrects for group heteroskedasticity. Country-specific income and own-price elasticities are calculated and indicate that poor countries are more responsive to changes in income and prices than rich countries. We also find evidence for the strong version of Engel's law; when income doubles, the budget share of food declines by approximately 0.10. 相似文献

The U.S. wine market experienced rapid growth in all facets—production, consumption, exports, and imports—over the past decade. Red wine imports more than tripled while consumption of domestically produced red wines doubled. This research estimates demand elasticities of U.S. red wine imports from five countries accounting for over 90% of imports—Italy, France, Spain, Australia, and Chile—using the first-difference version of the almost ideal demand system (AIDS). These elasticities are compared with those for domestically produced red wine. Results for conditional expenditure elasticities indicate that the U.S. red wine industry gains over imports when U.S. consumers' total expenditures on red wine increase. However, comparing own- and cross-price elasticities reveals an increase in the price of U.S. red wine results in a decline in quantity demanded six times greater than for French and Italian red wines and over 20 times greater than other import countries, thus harming the U.S. red wine industry. Empirical results suggest that U.S. red-wine producers could increase their total revenue by decreasing prices, while Italian and French producers can increase total revenues by increasing them. 相似文献

Both Samuelson's maturity hypothesis and the Anderson-Danthine state variable hypothesis are tested in this study of the variance of Treasury-bond futures prices. Both maturity and the quarterly refunding of Treasury debt have statistically and economically significant effects on futures price variance. The evidence for a monotonic maturity effect is highly statistically significant and robust to changes in model specification. The quarterly refunding is less statistically significant, and it is not clear whether the greatest effect is in the auction week or two weeks thereafter. Economically, these two predictable effects are of greater importance than a change in the discount rate. 相似文献

This study examines meat consumption in China, the world's largest meat consumer and producer, by considering both meat consumed at home and away from home based upon a diary‐based household survey. The results indicate that income growth leads to beef, poultry, other meat and pork away from home consumption to grow more than proportionally to total meat consumption. We also find that meats consumed away from home grow faster than at home counterparts due to higher income elasticities, suggesting that ignoring meat away from home could significantly underestimate current and future meat consumption. 相似文献
