The major countries of the former Soviet Union—specifically Russia, Ukraine, and Kazakhstan—are becoming increasingly important in world agricultural markets. The two main developments are that this region has become a large grain exporter, especially of wheat and barley, and Russia a big agricultural importer, especially of meat. These trends should continue for the next decade. However, policies to expand the livestock sector could mitigate these developments, as increased domestic meat production would reduce both meat imports and surplus feed grain for export. Also, further growth in the region's grain exports will require improvement in the infrastructure for storing and transporting grain. 相似文献

This study uses panel data to demonstrate two dimensions of land ownership: the distribution between households at a given time and changes within a household over time. We note that recognizing the latter dimension is only possible when analyzing rare long‐term panel data. We estimate a model for land ownership using a version of the correlated random effects estimator to uniquely identify the determinants of both dimensions amongst Kenyan smallholders. We find life cycle effects are a key determinant of both distributions, and identify important ways in which initial conditions such as inheritance and off‐farm income relate to the dynamics of ownership. We find that population density is a key determinant of differences between households, but also that a given household's land ownership is not affected in the short term as population density increases around them. Controlling for population density, households own more land when they are closer to road networks where the economic value of land is higher. We find important vulnerabilities for the land security of widows, but this vulnerability is geographically heterogeneous. 相似文献

Replacement brood cows are among the most significant investments for cow-calf operations, thus crucial to profitability. Many cow-calf producers find it cost effective to purchase replacements from a reliable replacement heifer seller, though by doing so they increase risk of reproductive inefficiency due to unknown characteristics of the heifers. When important information about a product is missing to buyers, a seller can build a reputation over time that acts as signal for quality. Previous work has explored reputation effects in feeder cattle markets, but to our knowledge we are the first to explore reputation effects in bred replacement cattle markets. Using data from an annual replacement heifer sale, we analyze the values of heifer characteristics and test for premiums from reputation development. After controlling for reproductive practices, breed, and other characteristics, we find reputation does not play the role that Shapiro theorized. In this sale, the lot order is strategically chosen and may indicate bred heifer quality to buyers, replacing the need for reputation as a signal. This study highlights the importance of quality signals and regional preferences in bred replacement cattle marketing and lays the empirical groundwork for future studies to test Shapiro's theory. 相似文献

Using a generalized error correction model, this article measures and compares market integration for export cash crops versus imported food crops for Mali and Nicaragua, and computes transmission elasticities between changes in the goods’ border and domestic prices. Both Mali and Nicaragua obtain the bulk of their export revenue from a particular agricultural commodity—cotton for Mali and coffee for Nicaragua—and both import the same key staple food of rice. To reap the economic gains from this trade specialization, the two countries’ agriculture must be well‐integrated into world markets. The two countries present an important policy contrast that affects their degree of world market integration and price transmission. In Mali, a parastatal enterprise controls its cotton industry, while Nicaragua has less state direction over agriculture. Reflecting this difference, the results show that for both its main export and import commodity, Nicaragua is more integrated into world markets and has higher price transmission than Mali. The results for Nicaragua also show much higher integration and price transmission for its main agricultural export (coffee) than its major import (rice). 相似文献

Behavioral economics (BE) examines the implications for decision-making when actors suffer from biases documented in the psychological
literature. This article considers how such biases affect regulatory decisions. The article posits a simple model of a regulator
who serves as an agent to a political overseer. The regulator chooses a policy that accounts for the rewards she receives
from the political overseer—whose optimal policy is assumed to maximize short-run outputs that garner political support, rather
than long-term welfare outcomes—and the weight the regulator puts on the optimal long run policy. Flawed heuristics and myopia
are likely to lead regulators to adopt policies closer to the preferences of political overseers than they would otherwise.
The incentive structure for regulators is likely to reward those who adopt politically expedient policies, either intentionally
(due to a desire to please the political overseer) or accidentally (due to bounded rationality). The article urges that careful
thought be given to calls for greater state intervention, especially when those calls seek to correct firm biases. The article
proposes measures that focus rewards to regulators on outcomes rather than outputs as a way to help ameliorate regulatory
biases. 相似文献

For economies with a large number of small firms, price induced changes in supply are decomposed into substitution and entry effects. Marginal firms (those earning zero profit) play a significant role in the determination of the slope of aggregate supply. 相似文献

Past field validity tests of contingent valuation have relied on voluntary contribution mechanisms to elicit actual willingness to pay, and may overestimate hypothetical bias because of free riding in the actual contributions. This paper argues that provision point mechanisms are a preferred alternative for field validity tests of contingent valuation because they increase the proportion of demand revealed in cases in which public goods can be provided in a step function. The results of a contingent valuation validity study of participation in a green electricity pricing program that uses a provision point mechanism are reported, and hypothetical open-ended and dichotomous choice responses are compared to actual participation. Calibration of hypothetical responses is also explored. 相似文献
