This article presents new estimates for investment and new growth accounts for three socialist economies between 1950 and 1989. Government statistics reported distorted measures for both the rate and the trajectory of productivity growth in Czechoslovakia, Hungary, and Poland. Researchers have benefited from revised output data, but have continued to use official statistics on capital input, or estimated capital stock from official investment data. Investment levels and rates of capital accumulation were much lower than officially claimed and over‐reporting worsened over time. A setback in factor accumulation—both investment in equipment and labour input—contributed very significantly to the socialist growth failure of the 1980s. 相似文献

Since 2002, the Institute for Peace Promotion and Injury/Violence Prevention (CISALVA) at the Universidad del Valle, Cali, Colombia and the Colombia Program at Georgetown University have developed and implemented 21 epidemiologically based municipal crime observatories in intermediate-sized municipalities in Colombia. These crime observatories serve as monitoring centres that provide low cost, geo-referenced methods of data collection and analysis, which allow cities to develop more responsive policies and prevention programmes and enhance governance. This article focuses on the methodology employed and lessons learned that may be applicable to similar settings. Worth noting within the results was a significant decrease in homicides after the first year of the programme. Whether or not such results could be attributed to the method or to the nature of the interventions and policy initiatives stemming from it remains open to conjecture. 相似文献

Production risk,risk aversion and the determination of risk attitudes among Spanish rice producers 总被引:1,自引:0,他引:1
Agricultural production is subject to risk and the attitudes of producers toward risk will influence input choices insofar as these affect production risk. Risk attitudes in turn may be affected by certain socioeconomic characteristics of producers. Using 2004 survey data from a cross‐section of 130 Spanish rice farms, we estimate risk‐aversion coefficients of farmers and investigate the influence of a series of socioeconomic variables on their risk attitudes. Our results show that farmers exhibit risk‐averse behavior and that risk attitudes are related to a series of socioeconomic characteristics. In particular, the belief that the farm will continue after the producer retires is found to increase the degree of risk aversion, while age is found to have nonlinear effects on risk aversion. Off‐farm income, especially from nonagricultural activities, is found to reduce risk aversion. Neither the educational level of the producer nor the presence of dependents on the household is found to have an effect on risk preferences. Regarding the production technology, we find that land, labor, and fitosanitary products are risk‐reducing inputs, whereas capital, seeds, and fertilizer all increase risk. 相似文献

One third of food destined for human consumption is wasted globally, and much of the food waste that comes from high-income or developed countries is caused by poor marketing practices, consumer behavior, and consumption patterns. The present study focuses on developed countries to propose some marketing actions that could help in reducing food waste. A comprehensive analysis was carried out for each marketing variable, to provide a snapshot of actions and proposals that are being developed. Our study highlights the relevance of marketing in contributing to reduce food waste, through the removal of “Buy one, get one free” sales promotions, clarifying date labeling, or raising food waste awareness campaigns. The main contribution of this study is the proposal of marketing actions that help in tacking food waste. 相似文献
