Long-term consequences of short-term precipitation shocks: evidence from Brazilian migrant households 总被引:1,自引:0,他引:1
We find that large short-term precipitation shocks damage the long-term income of households that have permanently migrated from rural to urban areas. This outcome is consistent with the behavior of credit-constrained rural households who are willing to accept lower long-term income in urban areas following the depletion of their productive assets during an adverse shock. Our empirical evidence suggests that there may be a link between large precipitation shocks in rural areas and urban poverty. Further exploration is warranted on the mechanisms by which natural disasters cause these long-term losses. 相似文献

Exploring perceptions and attitudes towards teaching and learning manual technical drawing in a digital age 总被引:1,自引:0,他引:1
This paper examines the place of manual technical drawing in the 21st century by discussing the perceived value and relevance of teaching school students how to draw using traditional instruments, in a world of computer aided drafting (CAD). Views were obtained through an e-survey, questionnaires and structured interviews. The sample groups represent professional CAD users (e.g., engineers, architects); university lecturers; Technology Education teachers and student teachers; and school students taking Scottish Qualification Authority (SQA) Graphic Communication courses. An analysis of these personal views and attitudes indicates some common values between the various groups canvassed of what instruction in traditional manual technical drafting contributes towards learning. Themes emerge such as problem solving, visualisation, accuracy, co-ordination, use of standard conventions, personal discipline and artistry. In contrast to the assumptions of Prensky’s thesis [(2001a) Digital natives, digital immigrants. On the Horizon 9, 5. NCB University Press Retrieved Oct 2006 from http://www.marcprensky.com/writing/Prensky%20-%20Digital%20Natives,%20Digital%20Immigrants%20-%20Part1.pdf; (2001b) Digital natives digital immigrants, Part 2: Do they really think differently? On the Horizon 9, 6. NCB University Press retrieved Oct 2006 from http://www.marcprensky.com/writing/Prensky%20%20Digital%20Natives,%20Digital%20Immigrants%20-%20Part2.pdf] of digital natives, the study reported in this paper indicates that the school students apparently appreciate the experience of traditional drafting. In conclusion, the paper illustrates the perceived value of such learning in terms of transferable skills, personal achievement and enjoyment. 相似文献

Animal companions play an increasingly important role in consumers' lives, and therefore many pets receive acceptance and treatment as members of the family. As the human-animal bond increases, so does consumer spending on pets, including that on high-dollar veterinary care. Unlike human health care, however, consumers must directly pay for the majority of high-dollar veterinary care. When an animal companion is ill, the consumer faces a stressful decision of whether even to engage in the treatment, along with the hardship of paying for it. Despite a rudimentary understanding of the factors relevant in the decision-making process regarding high-dollar veterinary care, knowledge is lacking about this often heart-wrenching choice. Using a depth-interview method, this study examines the decision-making process consumers go through when facing expensive medical treatment for their pets. The research results in an expansion of three a priori themes and the discovery and discussion of three factors that influence consumer decisions about veterinary care across all three themes. 相似文献

This study examines the effects of the Canada–U.S. exchange rate on bilateral trade of agricultural goods between the two countries and on U.S. farm income. Special attention is given to agricultural trade between the two countries under the Canada–U.S. Free Trade Agreement (CUSTA). This study utilizes two time series models: the vector error correction model (VECM) and the vector moving average model (VMA) with quarterly time series data from 1983 to 2000. It is found that the exchange rate has a significant impact on U.S. agricultural trade with Canada, but the impact on U.S. agricultural price and income is insignificant. The exchange rate between the two currencies is found to be weakly exogenous in the U.S. agricultural sector, which answers a fundamental question about the role of the exchange rate in Canada–U.S. bilateral trade for agricultural products. In addition, the results point to a significant, though minimal, effect on bilateral trade due to CUSTA. 相似文献

This study analyzes the impacts of alternative trade liberalization policies in the United States and the European Union (EU) on the U.S. sugar industry. A global sugar policy simulation model was used for this analysis. The study results indicate that the U.S. sugar industry may be able to survive if both the United States and the EU liberalize their sugar trade. However, if only the United States eliminates its sugar programs, all U.S. sugar-producing regions would be threatened. 相似文献

This article reports findings that suggest that trade union representation both protects worker interest and also facilitates the informal resolution of disciplinary disputes. However, this is dependent on robust representative structures and high‐trust relationships with employers. Conversely, non‐union companions were found to have no substantive impact on disciplinary processes and outcomes. 相似文献

Poorly developed equity markets inhibit the transfer of capitalownership. Moreover, the costs of transacting in equity marketsaffect not just the level of investment, but the kinds of investmentsthat are undertaken. Once equity markets allow the ownershipof capital to be transferred economically, reductions in coststend to favor the use of longer-maturity investments. When thereis a relationship between the maturity of an investment andits productivity, transactions cost reductions are conduciveto observing certain kinds of increases in productive efficiency.This article analyzes savings, investment, and consumption decisionsby using an overlapping generations model with two-period-livedagents. The analysis allows for several technologies for convertingcurrent output into future capital that vary by productivityand maturity, and it makes ownership of capital costly to transfer.A reduction in transactions costs will typically alter the compositionof savings and investment, and have potentially complicatedconsequences for capital accumulation and steady-state output. 相似文献
