Social conformity can spread social norms and behaviors through a society. This research examines such a process geographically and over time for voting, which is strongly influenced by the norm that citizens should vote. A mathematical model for the spread of voting participation under the influence of social conformity is developed based on the diffusion equation, and predictions are tested with spatial analysis of state-level voter turnout in American presidential elections from 1920 to 2008. Results show that voter turnout has converged to a stable equilibrium in its geographical distribution across the states—but it is an equilibrium that results in persistent differences at the state level. Results are compared to individual-level and agent-based models. The model may be applied to other types of social diffusion that depend on specific geographical location.  相似文献

Overfishing and excess capacity in mostfisheries around the world have generated considerableand increasing concern about their biological and economic performance ramifications. Theseproblems, in part, stem from substantialinvestment in technical improvements to boats andequipment in fishing fleets, which exacerbatesexcess fishing capacity and low returns tofishing effort and investment, given regulatoryand biological constraints. However, little attempt hasbeen made to quantify the extent or effects oftechnical change in fisheries. In this paper, we usedetailed data on innovation patterns for 19vessels in the Sète trawl fleet of southernFrance to evaluate the contributions oftechnical change to catch rates. We find thatembodied technical change enhanced productivity by approximately one percent per year between 1985 and 1999, but that external (disembodied) events counteractedthis trend, causing a net output decline ofabout three percent per year.  相似文献

This article first outlines the dynamics of what appear to be increasingly prevalent cycles of asset price inflation in liberalised financial systems, as well as the difficulties entailed in successful monetary policy responses. The article then analyses the Reserve Bank of Australia's policy responses to recent rises in credit growth and asset price inflation in the property sector. The Bank's responses are characterized in terms of an inflation‐plus targeting framework which has subtly redefined the Bank's approach to inflation targeting to include vaguely defined factors such as mediumterm‘risks’, as well as extending the time frame of such risk assessment. The article explains why, for a variety of reasons, the Bank has been reticent to fully declare its hand.  相似文献

We examine the effect of survey measurement error on the empirical relationship between child mental health and personal and family characteristics, and between child mental health and educational progress. Our contribution is to use unique UK survey data that contain (potentially biased) assessments of each child's mental state from three observers (parent, teacher and child), together with expert (quasi‐)diagnoses, using an assumption of optimal diagnostic behaviour to adjust for reporting bias. We use three alternative restrictions to identify the effect of mental disorders on educational progress. Maternal education and mental health, family income and major adverse life events are all significant in explaining child mental health, and child mental health is found to have a large influence on educational progress. Our preferred estimate is that a one‐standard‐deviation reduction in ‘true’ latent child mental health leads to a 2‐ to 5‐month loss in educational progress. We also find a strong tendency for observers to understate the problems of older children and adolescents compared to expert diagnosis. © 2015 The Authors.

This paper provides new estimates of the distribution of extended income amongst non-elderly, one-family households in the U.K. by combining household money income data and valuations of household production time. Extended income is substantially more equal than money income and extending the income definition changes income relativities significantly between families with and without earners and between married couple families and singles.  相似文献

This paper examines how economic policy-making changed as a result of the Asian crisis of 1997–1998, in the countries affected, in the region, and at the global level. It is perhaps surprising how little change has occurred in the broad approach to economic policy, but there is a much greater awareness of the vulnerabilities posed by large international capital flows. The broad tenets of the Washington Consensus, with its market-based policies, remain in place, but there is a recognition that well-functioning markets require complex institutions, rules, and procedures, and that these take time and effort to develop. Most of this institutional development will have to take place at the national level, but regional arrangements can offer support, and multilateral agencies, such as the International Monetary Fund, have learned from the crisis.  相似文献

This paper presents a simulation-based modelling approach for estimating total visitor numbers and amenity values for prospective non-priced open-access outdoor recreation sites. To begin, the geographic extent of the market for recreation at a policy site is estimated using data from a similar study site. The population residing within this geographic area is simulated using a spatial microsimulation model and GIS techniques and an individual-level ‘visitor arrival function’ is then transferred across this simulated population. This allows the latent demand for visits to the policy site by each simulated individual to be predicted and summed, providing an estimate of the total potential demand for recreation at the site. Combining this with an economic value measure of a visit provides an estimate of the potential amenity value of the policy site. The approach is applied to Moyode Wood, a small-scale forest in the West of Ireland, and estimates the potential total economic value of recreation at €0.4 million for the site. The research represents the first time that spatial microsimulation has been used in environmental benefit transfer and shows how it can be used to control for differences in demographic and spatial factors between study and policy sites. It also demonstrates how individual-level single-site travel cost models estimated using on-site survey data can be used to predict demand at alternative policy sites.  相似文献

A circular metropolitan area consists of a central city surrounded by a suburb. Households sort over the two jurisdictions based on public service levels and their costs of commuting to the metropolitan center. Using numerical simulations, we show that (1) there typically exist two equilibria: one in which the poor form the voting majority in the central city and the other in which the rich form the majority in the central city; (2) there is an efficiency vs. equity trade-off as to which equilibrium is preferred; and (3) if the central city contains only poor households, equity favors expanding the central city to include rich households. The third result arises not because of a fiscal subsidy from rich to poor households induced by a property tax but rather because of a change in house price capitalization.  相似文献

Public Investment, Congestion, and Private Capital Accumulation   总被引:8,自引:0,他引:8  
This paper analyses the impact of public investment on the dynamics of private capital formation in an intertemporal optimising market-clearing framework. The key feature characterising the analysis is that the public good is treated as a durable capital good, subject to congestion. We show how in the presence of congestion the effect of government investment on private capital formation involves a tradeoff between the degree of substitution between private and public capital in production and the degree of congestion. Both lump-sum and distortionary tax financing are considered, with this tradeoff being tightened in the latter case  相似文献
