Factors explaining the diffusion of hybrid maize in Latin America and the Caribbean region 总被引:1,自引:0,他引:1
If future demand for maize in Latin America and the Caribbean region (LAC) is to be met from local sources, domestic production must continue to increase. Because further expansion in the area planted to maize is precluded by the limited availability of arable land, future increases in production will have to rely heavily on the spread of productivity‐enhancing hybrid technology. Until now, the diffusion of hybrid maize in LAC has been quite variable. Using data from 18 countries, we investigate factors affecting the hybrid maize diffusion rate. Our findings validate conventional profitability‐based explanations of producer adoption behavior, but they also confirm the importance of supply‐side factors, thereby providing empirical support for the life cycle theory of seed industry development. We conclude that if policy makers in LAC are to accelerate the diffusion of hybrid maize, they will have to ensure an environment in which it is not only profitable for producers to adopt improved germplasm, but also profitable for the seed industry to produce and sell high‐quality seed. 相似文献

Empirical evidence from the 1980s and 1990s indicates that cash use in the U.S. remains high even though there has been a
proliferation of alternatives to cash. This paper examines the dynamics of inflation and asset prices in response to innovations
in the efficiency of processing noncash transactions. The quantitative results suggest that inflation is more sensitive than
nominal interest rates or real equity prices to innovations in the efficiency of non-cash payments processing. Thus, as alternatives
to cash payment become more prominent, the volatility of real interest rates may increase.(JELE31, E41, G12)

This research aims at assessing the environmental impact of the poultry supply chain from cradle to grave using case study research and also life cycle assessment (LCA). While a limited number of generic poultry production LCA studies have been published, fewer yet assess the whole process of a specific organisation, none comparing the increased impact of further processing. Our results show that irrespectively of the impact assessment method utilised, the process of producing portions is considerably higher in total environmental impact due to the extra raw material required to produce the same mass into retail. Our research contributes to the growing number of LCA studies and could be used by practitioners for comparison against national and international averages. From a theoretical point of view, this research provides new insights into the relationship between vertically integrated supply chains and environmental performance which has not been examined in the past. 相似文献

Using a sample of listed French firms in 2005, the year of mandatory IFRS adoption in the European Union (EU), we investigate the determinants of disclosure compliance of stock option expenses under IFRS 2, Share‐based Payment. Stock options are a popular means of executive compensation in France relative to other EU countries. Prior to 2005, French accounting standards and corporate governance regulations did not require recognition of option expense amounts and required minimal supplementary disclosures. There was also a perception that enforcement was imperfect, in particular with respect to IFRS 2. Given this setting, we explore what factors influence the willingness of firms to follow compulsory IFRS requirements in a weak regulatory setting. We find that overall compliance with IFRS 2 disclosure requirements increases with U.S. and U.K. institutional ownership, U.S. cross‐listing, provision of English language statements, and decreases with CEO and family ownership of the firm. We also investigate how stock market prices are affected by the recognition and disclosure of stock option expenses according to IFRS 2 in this regulatory setting and find that investors value option expenses positively, particularly when accompanied by high‐disclosure compliance. Our findings have implications for other jurisdictions in the process of adopting or converging to IFRS. 相似文献

The paper examines a union initiative to recruit among migrant workers through the provision of individual services outside of the workplace. While the initiative is shown to have initially generated new members, questions are raised about the viability of such an approach in the absence of mutually supportive access to workplace representation. 相似文献

We present a meta-analysis of cycle periods in historical socio-economic data found in the K-wave literature. The literature on stochastic and deterministic cycles in variables such as the consumer price index, employment, interest rates, commodity prices, GDP, war and hegemony is huge and scattered. However our meta-analysis reveals various commonalities. Our key finding is that there is a common set of cycle periods that is common across most socio-economic variables. 相似文献

Macroeconomic policy decisions in real-time are based on the assessment of current and future economic conditions. Crucially, these assessments are made difficult by the presence of incomplete and noisy data. The problem is more acute for emerging market economies, where most economic data are released infrequently with a (sometimes substantial) lag. This paper evaluates nowcasts and forecasts of real GDP growth using five models for ten Latin American countries. The results indicate the flow of monthly data helps to improve forecast accuracy, and the dynamic factor model consistently produces more accurate nowcasts and forecasts relative to other model specifications, across most of the countries we consider. 相似文献

This represents one of a series of studies of the Longitudinal Emergency Medical Technician Attributes and Demographics Study (LEADS) being undertaken by the National Registry of Emergency Medical Technicians and the National Highway Traffic Safety Administration (NHTSA). This secondary analysis of the LEADS database, which provides a representative sampling of EMTs throughout the United States, examines the effects of instructor quality on the level of preparedness of emergency medical technicians (EMTs). Results showed significant differences, based on instructor quality, in the ratings on ten dimensions of EMT preparedness for both EMT Basics and EMT Paramedics. Implications for HRD practitioners, adult educators and researchers are discussed. 相似文献
