Henry George:     
ABSTRACT While generally known today for his famous proposal for a Single Tax, Henry George has not been widely recognized as one of the first economists to write about the possibility of political market failure. Based on his appreciation for the allocational efficiency of markets and his suspicion of government intervention, George was an early advocate of public choice ideas who repeatedly warned of the dangers of rent seeking.  相似文献

The supply chains for agri-food products in Canada are being shaped by a number of forces including the globalization of markets, technological change and the increased focus by consumers — both domestically and internationally — on issues such as food safety, quality assurance and environmental sensitivity. This paper explores these changes, offering an explanation of why they are occurring, discussing the driving forces for change and providing examples from alternative supply chain structures in the Canadian agri-food sector.  相似文献

Analyzing Real Estate Data Problems Using the Gibbs Sampler   总被引:2,自引:0,他引:2  
Real estate data are often characterized by data irregularities: missing data, censoring or truncation, measurement error, etc. Practitioners often discard missing- or censored-data cases and ignore measurement error. We argue here that an attractive remedy for these irregularity problems is simulation-based model fitting using the Gibbs sampler. The style of the paper is primarily pedagogic, employing a simple illustration to convey the essential ideas, unobscured by implementation complications. Focusing on the missing-data problem, we show dramatic improvement in inference by retaining rather than deleting cases of partially observed data. We also detail Gibbs-sampler usage for other data problems.  相似文献

The debt-to-the-future issue is discussed taking into account that it is not simply a poetic or innocent statement but a present complex problem. An analytical approach through the issue of risk and uncertainty might allow us to delimit our reflection. At the same time, it might become the main axis in the reality we face today, since risk, reliability, and uncertainty appear as characteristic features of modern society. Participatory processes, as manifestations of post-normal science, are proposed as a way to cope with uncertainty.  相似文献

We present a tractable, dynamic general equilibrium model of state‐dependent pricing and study the response of output and prices to monetary policy shocks. We find important nonlinearities in these responses. For empirically relevant shocks, this generates substantially different predictions from time‐dependent pricing. We also find a distinct asymmetry with state‐dependent pricing: Prices respond more to positive shocks than they do to negative shocks. This is due to a strategic linkage between firms in the incentive for price adjustment. Our state‐dependent model can account for business cycle asymmetries in output of the magnitude found in empirical studies.  相似文献

Bruce E. Tonn 《Futures》2007,39(9):1097-1116
This article presents a strategic framework to guide public policy with respect to very long-term futures. The framework is based upon three fundamental principles. Threats to meeting the principles are assessed. Integrated planning responses to overcoming the threats are proposed. Significant changes in economic, political and social theory and organization required to support the strategic responses are discussed. It is argued that human civilization would need to pass through the mythic ‘singularity’ on the path to futures sustainability.  相似文献
