THE EFFECT OF INSTITUTIONAL INTEREST ON THE INFORMATION CONTENT OF DIVIDEND-CHANGE ANNOUNCEMENTS

We test the hypothesis that the information content of dividend-change announcements, as reflected in stock prices, is directly related to the degree of pre-announcement information asymmetry in the stock. The dividend-change announcements include initiations, large increases, large decreases, and omissions. Information asymmetry is proxied by the proportion of stock held by institutions. Consistent with the hypothesis, we document a significantly positive relation between the absolute values of the announcement-period excess returns and the degree of pre-announcement information asymmetry in the stock. This finding appears to hold for all types of dividend changes except dividend omissions.     

Fiscal Decentralization and Poverty Alleviation in a Transitional Economy: The Case of Viet Nam

Intergovernmental fiscal arrangements may play an important role in ameliorating poverty in many countries. Successful poverty alleviation generally requires both ‘capacity improving’ and ‘safety net’ policies, and both types of policies may, to some extent, be implemented through, or affected by, intergovernmental transfers. From this perspective, we analyse the efficacy of intergovernmental fiscal arrangements in poverty alleviation in a transitional economy, Viet Nam. We argue that both general and specific transfers are needed for this purpose: the former to enable all provinces to provide a given basket of public services at a given tax-price by offsetting their revenue and cost disabilities and the latter to ensure that minimum levels of those public services provided by lower levels of government are targeted to the poor throughout the country.     

土地登记代理执业风险及防范

所谓土地登记代理执业风险是指土地登记代理人因在执业过程中未能完成代理事项或未能正确履行代理职责所要承担的法律责任。它主要表现为因代理违约而产生的违约风险、因代理失败或代理不当而产生的风险等。虽然典型的土地登记代理纠纷案例并不多见,但其潜在的执业风险业内人士应予以足够的重视。土地登记代理风险的成因产生土地登记代理风险的原因是多方面的,从根本上说,主要来源于委托人、土地登记代理人及其代理机构自身和土地登记代理人的执业环境三个方面。因委托人产生的风险因素1.委托人的委托意向。委托人委托代理人进行土地登记的…     

May’s theorem in an infinite setting

We generalize May’s theorem to an infinite setting, preserving the elementary character of the original theorem. We define voting scenarios and generalized voting scenarios, and prove appropriate versions of May’s theorem. The case of generalized voting scenarios specialized to a countably infinite set of voters and the collections of all coalitions that have asymptotic density, shows that majority rule is the only aggregation rule that satisfies neutrality, irrelevance of null coalitions, anonymity, and positive responsiveness.

PRICE HETEROGENEITY AND "REAL" INEQUALITY: A CASE STUDY OF PRICES AND POVERTY IN RURAL SOUTH INDIA

This paper, based upon a case-study of three Indian villages, studies whether households within the same market pay different prices for identical goods. It is found that not only are unit prices for food heterogeneous, but that the poor pay more for the same goods than the rich. This is because liquidity constraints force poorer households to purchase goods in small quantities and consequently subject them to quantity premiums. Household specific index numbers are used to adjust nominal incomes to real values and it is found that Gini coefficients of real incomes are between 12 percent to 23 percent greater than the Gim for nominal incomes. An econometric analysis of the determinants of prices shows that incomes are negatively correlated with prices, as is family size, but that the amount of land owned shows a positive relationship.     

Agricultural Supply Response: A Survey

This paper surveys the literature on agricultural supply response to prices in developing countries. Empirical estimates of elasticities depend both on the methodology adopted and on country-specific factors relating to technology, economic structure and macro constraints. The paper seeks to establish some general conclusions on supply responsiveness within these limitations. Supply response to output prices at the aggregate and at the crop levels is considered first. Crop-specific acreage elasticities range between zero and 0.8 in the short run while long-run elasticities tend to be higher — between 0.3 and 1.2. Yield elasticities are smaller and less stable than acreage elasticities. Clearly, inter-crop pricing can be relied upon to effect shifts in the commodity composition of agricultural output. Evidence also suggests that supply elasticities vary systematically with such factors as price and yield risks, multiple-cropping, the importance of the crop, farm incomes, farm size, tenancy and literacy. The most controversial and important aspect of supply response is the effect on aggregate agricultural output of agriculture's terms of trade. Conventional time-series estimates range from 0.1 to 0.3. A major cross-country study reports an aggregate elasticity as high as 1.66. It is argued that cross-country estimates are apt to exaggerate aggregate responsiveness while time-series studies underestimate it somewhat. For LDCs, a tentative range of 0.4 to 0.5 seems plausible. Hence, the distributive effects of the terms of trade are likely to be more significant than the allocative effects. Asian evidence shows that only a third of the inter-country differences in fertilizer use can be attributed to fertilizer price policies. Provided new technologies and infrastructure are in place, fertilizer subsidies can help in technology diffusion and in overcoming credit constraints. The choice between price supports and input subsidies will depend on a variety of country- or situation-specific factors. Nevertheless, a significant general factor favoring price supports is that they can more easily be coupled with price stabilization goals than input subsidies. Though sparse, the available evidence on the response of marketed surplus suggests that price policy is not a reliable instrument for regulating inter-sectoral trade.     

Market Segment Response Through Field Experimentation

A key assumption underlying segmentation studies is that marketing efforts have differential effects on market segments. This question was investigated in the context of a field experiment involving enlistment in the armed forces. Approximately 8000 completed questionnaires administered at various stages in the US Navy enlistment recruiting process were collected at two points in time, corresponding to a pre- and post-experimental intervention. Attitudinal data were analysed to identify meaningful segments. Differential responses of market segments to advertising and recruiter changes were found, providing direction for evaluation of, and changes in, the creative component of advertising.     

Linking Order Fulfillment Performance to Referrals in Online Retailing: An Empirical Analysis

Referral management for online retailers is a strategically important activity, as referrals offer a highly cost‐effective method of customer acquisition. In fact, online customers mention referrals as the second‐most common reason for choosing to shop at a particular retailer, second only to search engine suggestions. However, while online retailers are able to improve their visibility on search engines through focused keyword insertions, they are often unable to pinpoint the drivers of referral behavior among their customers. The current research examines the relationship between two key dimensions of online retailing: order fulfillment cycle times and referral behavior. Employing a theory of customer appraisal and empirically testing the ensuing model using structural equation modeling, we find that excellent order fulfillment is instrumental in generating referrals for the online retailer, even after factoring in product quality.     

Sedimentation of reservoirs in India

The sedimentation of Indian reservoirs has become a serious problem due to the synergistic action of population growth, intensity of agricultural operations, poor soil conservation and deforestation. This article examines the reasons for and responses to, sedimentation in three Indian reservoirs — Nizamsagar, Tungabhadra and Sriramsagar. The land management practices adopted in each case are analysed with reference to current and future needs. The article highlights particularly the need to monitor methodically the land use changes in the catchments of reservoirs.
