There is growing interest in Nova Scotia's Environmental Farm Plan (NS EFP) program among farmers and policy makers because of several reasons. First, effectiveness of standardized or uniform beneficial management practices in mitigating the negative environmental impacts from agriculture is limited by inherent heterogeneities in agricultural production systems. In addition, there is heightened interest in farmers generating ecological goods and services to society. This study investigates the determinants of participation in the NS EFP program. A discrete choice model of NS EFP participation was applied to a sample of 83 farmers (representing a 31% response rate). To increase relevance of the study to program administrators, the study also examined farmers’ use of various channels and sources of information on farm conservation practices. The most used sources of information on farm conservation practices include a mix of interpersonal sources and government agencies. Although online information (especially those available for free) appears to be gaining popularity in usage, overall, electronic and computer channels of information (especially radio and television) were used less compared with traditional channels of communicating farm conservation information (such as newsletters and agricultural magazines). Regression analysis suggests that farm characteristics (i.e., farm type, farm size, farm income) and farmer capacity variables (i.e., specialized training and knowledge from EFP program information sessions and workshops, and on-farm stewardship demonstrations) were significant determinants of environmental farm planning. 相似文献

In this paper we investigate the macroeconomic impact of natural disasters in developing countries by examining hurricane strikes in the Central American and Caribbean regions. Our innovation in this regard is to employ a wind field model on hurricane track data to arrive at a more scientifically based index of potential local destruction. This index allows us to identify damages at a detailed geographical level, compare hurricanes' destructiveness, as well as identify the countries that are most affected, without having to rely on potentially questionable monetary loss estimates. Combining our destruction index with macroeconomic data we show that the average hurricane strike caused output to fall by at least 0.83 percentage points in the region, although this depends on controlling for local economic characteristics of the country affected and what time of the year the storm strikes. 相似文献

Sufficient conditions for a unique price equilibrium, in terms of the uncertainty distribution and the state contingent consumer distributions, are given for spatial duopoly. Also considered are efficiency and endogenous locations for the symmetric case and comparative statics on price flexibility. 相似文献

This paper examines empirically whether the expected and unexpected components of monetary policy have nonlinear impacts on the dynamics of REIT returns. Empirical results find the nonlinear response of REIT returns to expected and unexpected components of monetary policy. The unexpected component of monetary policy plays a more prominent role in influencing REIT returns than does the expected component of monetary policy. Specifically, unexpected contractionary monetary policy has a significantly adverse impact on REIT returns, and the adverse effect in a bust market is stronger than in a boom market. In addition, the unexpected monetary policy will also affect the boom-bust dynamics of REIT returns through its effect on the time-varying transition probability matrix. The tightening of the expected and unexpected components of monetary policy will enhance the probability that the REIT market will stay in the bust regime. 相似文献

In many situations the individuals who can generate some output must enter a contest for appropriating this output. This paper analyses the investment incentives of such agents and the role of incumbency advantages in the contest. Depending on the advantages, an increase in the productivity of the investment can decrease or increase the amount of investment. The results are applied to autocrats’ investment behavior and job specific investment in organizations. 相似文献

This paper compares the deterrence provided by a competitive media sector towards government induced corruption with that of a media monopoly in a setting where the media might raise both true as well as false allegations of corruption. It finds that competition’s impact on corruption deterrence is not necessarily better than a monopoly but rather hinges on a delicate balance between government’s kickback from corruption and the media’s potential benefit from exposure. While the paper does identify conditions in which a competitive media sector would improve upon the deterrence provided by a monopoly, it also find conditions under which it would do no better than a monopoly and in some situations its strategic response could be even worse especially when it intensifies effort towards justifying false allegations. 相似文献

The trend in crop yields and yield variability affects food security and impact agricultural and food policies. Recent studies in this area have either focused only on one country or performed global analysis on a handful of crops. We provide the first worldwide analysis of trend and variability for 8088 country-crop yield series taken from the FAO database, employing a robust estimator to cope with the adverse statistical effects of outliers. More than half of the series display a slowdown in yield growth due to a closing of the gap between realised and attainable yields as well as to agricultural policies promoting more sustainable agricultural practices. Around one fourth of the series show also an increase in yield variability as a consequence of climate change and changes in farm management practices. Yield variability is highest in Eastern Europe, Central Asia and Middle East and North Africa, where food security may be threatened. 相似文献

采用Super-SBM方法将环境因素作为非期望产出纳入旅游经济效率测算框架,结合空间计量经济方法分析2005—2016年我国省域旅游经济效率空间关联性及影响因素溢出效应,结果显示:环境约束下,我国省域旅游经济具有一定的空间集聚趋势,呈现出"东南热、西北冷"的分布特征,尚未实现网状结构均衡发展;我国省际旅游经济效率间存在显著的空间溢出作用。对于环境约束下旅游经济效率发展来说,人均GDP、技术创新、市场化、环境规制均有显著的正向作用,路网密度作用不显著,外国直接投资(FDI)有显著的负向作用。影响因素的溢出效应来看,市场化、经济增长、技术创新具有显著的积极间接溢出效应,但环境规制带来了显著的负向间接溢出效应,FDI与路网密度的间接溢出效应不显著。 相似文献
