The demand for Toll Free Numbers (TFNs) languished from 2000 to 2008; however recent growth in demand caused the FCC to open a new toll-free code (855) with the possibility of new code openings in the next three years. The analysis here indicates the demand for TFNs is highly inelastic (the coefficient for own price elasticity for TFNs is approximately −0.04). This has implications for concerns regarding future exhaust of toll-free codes and the price structure for recovery of SMS/800's costs. This article considers the effects of the limited property rights for TFN, and welfare implications of gray markets for vanity TFNs. The FCC's allocation mechanism for new 855 codes is considered and whether other allocation mechanisms, such as auctions, could be welfare superior. 相似文献

This paper explores whether expert judgements can be taken as a proxy for citizen preferences for determining investment strategies for public goods. As an illustration, we focus on the provision of Public Rights Of Way (PROW) by Local Government Authorities in England. These provide rights of passage over property to those other than the owners, and little information is available on the welfare effects of changes in the provision and use of PROW. Given limited funds, reliance on expert judgement could be a cost effective alternative for decision-making compared with stated preference surveys of citizens. Two methods are compared. The Analytic Hierarchy Process (AHP) is used to elicit expert judgement to proxy citizen preferences for different attributes of PROW. The Choice Experiment (CE) technique is then used to derive preferences directly through personal interviews with citizens. Overall it was found that judicious use of AHP by experts can, in this instance, be used to represent citizen views. However, this result may not be easily generalisable to other settings. 相似文献

The European Treaty supports the application of the polluter pays principle in all environmental policies including the Water
Framework Directive. This paper assesses the efficiency of water-charging systems in two European regions. The regions examined
are the South west region of Ireland and the Navarre region in Spain which were selected because they are similar in terms
of economic indicators but different in terms of water pricing structures. The paper describes the development and application
of a simple model to analyse data on water-charging systems from these two regions. We present the results of a detailed scenario-based
investigation illustrating the differences between experience, composition and basis, impact and constraints on the application
of water charges for both regions. The key findings are that existing water charges do not provide incentives for users to
use water efficiently and thereby do not contribute effectively to the environmental objectives of the Water Framework Directive. 相似文献

This survey provides an updated review of the empirical literature on the regional effects of monetary policy in economic activity by means of undertaking a threefold perspective. First, the main methodological dimensions of this literature are examined while pinpointing those modelling or methodological traits that constitute a source of diverging estimates and thereby produce inconclusive evidence. Secondly, the estimates yielded by the literature are summarized by carrying out a cross‐study analysis of the results for each monetary union. By drawing on empirical regularities that are robust across studies, the conclusiveness of the results is assessed, while those monetary unions for which conclusive evidence is still lacking are also identified. Lastly, the sources of regional heterogeneity identified by these studies are reviewed in order to shed some light on the linkage between monetary policy and territorial heterogeneity. As a result of this threefold perspective, this survey delivers overall structured conclusions and updated policy‐relevant lessons. Moreover, various research gaps and emerging topics in the literature are also identified. 相似文献

This study explores how farmers' managerial behavior in their production planning processes influences the economic performance of their farms, measured through input‐oriented and output‐oriented technical efficiency. A conceptual framework in which differences in managerial behavior were assumed to be due to bounded rationality was developed. The 3‐year means (2006–2008) from a panel data set on grape‐producing family farms in FYR Macedonia were analyzed. Technical efficiency was estimated with the nonparametric data envelopment analysis approach. The impact of farmers' managerial behavior was assessed in a second‐stage regression. The results suggest that bounded rationality in farmers' production planning decisions causes inefficiency. Copyright © 2011 John Wiley & Sons, Ltd. 相似文献

Fishing in the Tsitsikamma National Park has officially been halted since 2001. However, the desire to fish in the Marine Protected Area remains high among the local communities in Tsitsikamma. This has led to illegal fishing practices in the park. Consequently, the reaction of the local communities was measured using semi-structured questionnaires, informal interactions, personal observations, and through a key informant workshop that was organized in the Tsitsikamma National Park. It was found that responses from local communities to fishing within the park were defined by their residence status, ethnicity, gender, income, and educational level. There is a general understanding by local communities that the purpose of the Tsitsikamma National Park is to conserve nature within its boundaries. However, there is a mismatch in the understanding of the term ‘conservation’ between the local communities and conservation officials of the South African National Parks (SANParks). Local communities consider conservation to include sustainable utilization while conservation officials from the practice pursue absolute protection of the marine fisheries resources. The majority of local communities in Tsitsikamma resent this SANParks ‘no-take’ policy on fishing. They would like access to the fisheries resources in the Tsitsikamma National Park for both subsistence and recreational purposes. 相似文献

We investigate the determinants of wages in Zambia and based on the quantile regression approach, we analyze how their effects
differ at different points in the wage distribution and over time. We use three cross-sections of Zambian household data from
the early nineties, which was a period of economic transition, because items as privatization and deregulation were on the
political agenda. The focus is placed on the public-private sector wage gap, and the results show that this gap was relatively
favorable for the low-skilled and less favorable for the high-skilled. This picture was further strengthened during the period
1991–1996. 相似文献

We examine natural disasters and long‐run climatic factors as potential determinants of international migration, implementing a panel dataset of bilateral migration flows from 1960 to 2000. We find no direct effect of long‐run climatic factors on international migration across our entire sample. These results are robust when conditioning on origin‐country characteristics, when considering migrants returning home, and when accounting for the potential endogeneity of migrant networks. Rather, we find evidence of indirect effects of environmental factors operating through wages. We find that epidemics and miscellaneous incidents spur international migration, and there is strong evidence that natural disasters beget greater flows of migrants to urban environs. 相似文献

We analyze normalized productivity differences for 15 developing Latin American countries and four firm types: National Domestic, National Exporter, Foreign Domestic, and Foreign Exporter. There are no productivity thresholds for viability, export activity, or multinational activity, but we do find a clear size productivity premium and development productivity premium in the manufacturing sectors. We also find a clear foreign-ownership productivity premium, both for domestic firms and for exporting firms and both for manufacturing sectors and services sectors. In contrast, we only find an export productivity premium for national firms in the manufacturing sectors. 相似文献

We document that immigrants in the United States differ from natives in several aspects relevant for their financial decision making. Based on these differences, we designed novel financial education materials targeted at US immigrants and their children and evaluated their effectiveness using a randomized control trial. To the best of our knowledge, this is the first rigorous evaluation of financial education programs targeted at this population. Compared to a control group, the groups that received the one‐time educational intervention were more likely to correctly answer financial knowledge questions immediately after the intervention. The estimated effects of this one‐time intervention on knowledge were large, but most of them faded away after six months. Moreover, we find little effect of the treatments on intended financial behavior measures, both immediately and six months later. Our results point to the efficacy of this type of educational material in informing immigrants and their children about important financial information that they are unfamiliar with, including information related to their immigrant status. However, they also suggest that a priority for future research should be to test whether repeated opportunities for learning can increase financial knowledge retention and lead to behavior change. 相似文献
