This study examines the impact of stock split and stock dividend announcements made by closed end mutual funds. We argue that the asymmetric information / signaling hypothesis does not apply to mutual funds. Therefore, any announcement effects must be attributed to other factors such as the optimal trading range hypothesis. We find that closed end funds react no differently than other firms to stock distribution announcements; also, trading volume and turnover remain unchanged after closed end funds' ex-stock distribution days, while liquidity declines for other firms that distribute shares. 相似文献

Improving agricultural productivity has received a greater attention in recent years amid concerns about rising food insecurity, population pressures, and climate change. Many believe that better access to institutional credit, spanning microcredit as well as commercial and agricultural banks, can help rural households smooth risks, and access inputs and other technology to modernize agriculture and improve farm/nonfarm linkages. We use recently augmented household panel data spanning over 20 years in Bangladesh to examine the effects of rural credit expansion (both microcredit and formal bank channels) on outcomes for agricultural households. We find that microcredit has benefited households with lower landownings, raising agricultural income from activities such as livestock rearing that require less land, as well as nonfarm income diversification for all households, but with the strongest effect for landless or near‐landless households. We do not find effects of microcredit on crop income, but do, however, find that reported supply‐side credit constraints significantly lower crop income. Borrowing by both men and women has contributed to nonfarm income growth for marginal farmers, but only men's borrowing has contributed to nonfarm income growth among higher landowning groups. 相似文献

Several studies in finance and accounting literature have measured security returns subsequent to some economic events over long horizons by cumulating the returns over time. It is well known that when single period returns are cumulated over long horizons, the bid–ask error in the measured returns could be very high. One way of estimating the bid–ask error is by simulation. This paper offers an alternative to the simulation approach and provides a closed form expression for the bid–ask error in cumulated returns. Our analytical approach has two main advantages over the traditional simulation method; first it quantifies the bias precisely and second, it is computationally simpler by several orders of magnitude. 相似文献

This article values the groundwater recharge function performed by the Hadejia–Jama'are floodplain which is threatened by planned upstream water utilization schemes. Domestic consumption of groundwater resources for households dependent on groundwater resources is analyzed. Three types of households are identified as ( i ) those which collect all their water, ( ii ) those which purchase all their water, and ( iii ) those which both collect and purchase water. A behavioral model using a household production function approach is developed to model water demand and a panel formed by pooling contingent behavior and observed data is used to estimate demand. Welfare changes are calculated based on these estimates and on hypothetical reductions in the groundwater recharge rate. 相似文献

This paper analyses the effect of a set of irrigation rehabilitation projects conducted over the last 10 years in Peru. The projects were conducted without the aim or the tools for a full‐fledged impact evaluation. Nevertheless, this paper attempts an evaluation through the use of alternative data sources such as household surveys and geographic information, a strategy of identification of beneficiaries and control households based on spatial proximity to the projects’ sites, and an econometric approach consisting of a double‐differencing technique. The empirical analysis is guided and interpreted with the help of a theoretical model that considers the effects of an irrigation project on the distribution of production, employment and income for different types of landowners. The paper concludes that the irrigation projects implemented in Peru had a positive impact on intended beneficiary households, but not in the way it could have been simplistically expected. The project did benefit the poor but not by increasing production in their own small plots but by providing them with better employment opportunities in larger farms. 相似文献

This article presents the results of a hedonic property value analysis for an urban watershed in New Haven County, Connecticut. We use spatially referenced housing and land-use data to capture the effect of environmental variables around the house location. We calculate and incorporate data on open space, land-use diversity, and other environmental variables to capture spatial variation in environmental quality around each house location. We are ultimately interested in determining whether variables that are reflective of spatial diversity do a better job of describing human preferences for housing choice than broad categories of rural versus urban areas. Using a rich data set of over 4,000 houses, we study these effects within a watershed that includes areas of high environmental quality and low environmental quality as well as varying patterns of socioeconomic conditions. Our results suggest that, in addition to structural characteristics, variables describing neighborhood socioeconomic characteristics and variables describing land use and environmental quality are influential in determining human values. We also find that the scale at which we measure these spatially defined environmental variables is important. 相似文献

New Product Development Structures: The Effect of Customer Overload on Post-Concept Time to Market 总被引:1,自引:0,他引:1

In corporate policy statements, seminars, journal articles—even in television commercials—the message comes through loud and clear: To remain competitive, we must do a better job of listening to our customers. Through close contact with customers, designers can more accurately identify market requirements, quickly refine product specifications, and thus reduce time to market. However, too much customer input can create confusion and duplication of effort, which ultimately increases time to market. In other words, some firms run the risk of over-listening to their customers. In a study of three global players in the electronic component industry, Srikant Datar, Clark Jordan, Sunder Kekre, Surendra Rajiv, and Kannan Srinivasan explore the effects of having too much input from customers. Specifically, they examine the relationship between a company's new product development structure and the volume of customer input, which in turn can affect time to market. The high-tech, fast-cycle firms examined in this study employ two distinct new product development structures: concentrated and distributed. A concentrated structure locates all product designers in one facility. This facilitates cross-product learning among designers, but limits designers' contact with customers and process engineers. A distributed structure disperses new product development among numerous manufacturing sites, giving designers close contact with customers and process engineers. However, a distributed structure limits designers' opportunities for cross-product learning. Analysis of 220 new product efforts reveals that the distributed structure offered a time-to-market advantage as long as these firms efficiently managed the level of customer interaction. When designers received input on the product design from no more than 25 customers, the distributed structure provided shorter time to market than the concentrated structure. Beyond the 25-customer level, time-to-market performance of the distributed structure degraded quickly and at an increasing rate. In such cases, more effective management of customer interaction might allow firms employing a distributed structure to enjoy the benefits not only of customer input, but also of improved coordination between product designers and process engineers. 相似文献

Valuing groundwater recharge through agricultural production in the Hadejia-Nguru wetlands in northern Nigeria 总被引:2,自引:0,他引:2
This study applies a production function approach to value the groundwater recharge function of the Hadejia‐Nguru wetlands in northern Nigeria. The groundwater recharge function supports dry season agricultural production which is dependent on groundwater abstraction for irrigation. Using survey data this paper first carries out an economic valuation of agricultural production, per hectare of irrigated land. We then value the recharge function as an environmental input into the dry season agricultural production and derive appropriate welfare change measures. Welfare change is calculated using the estimated production functions and hypothetical changes in groundwater recharge and hence, groundwater levels. By focusing on agricultural production dependent solely on groundwater resources from the shallow aquifer, this study establishes that the groundwater recharge function of the wetlands is of significant importance for the floodplain. 相似文献

Balancing Performance Measures 总被引:8,自引:0,他引:8

This paper uses an agency theory model in which the agent's actions are multi-dimensional to analyze the optimal weights to apply to performance measures in a compensation contract. We show how the optimal contract trades off the congruity of the overall performance measure with the desire to minimize the risk imposed upon the agent. In contrast to the single action case, we find that an increase in the sensitivity of a performance measure to an agent's action does not necessarily increase the weight placed on that performance measure, even if that measure is perfectly congruent with the firm's outcome. 相似文献
