This study attempts to determine the causal relationship between budget and current account deficits as well as the direction
of such causality. A selected sample of some developed and developing countries with annual time series data is used and cointegration
techniques are applied to bring evidence regarding this important issue. Our results do not support any long-run relationship
between the two deficits for developed countries while the data for developing countries do not reject such a relationship.
However, our results suggest a causal relationship between the two deficits for most of the sample countries.

Unlike standard auctions, we show that competitive procurement may optimally limit competition or use inefficient allocation rules that award the project to a less efficient firm with positive probability. Procurement projects often involve ex post moral hazard after the competitive process is over. A procurement mechanism must combine an incentive scheme with the auction to guard against firms bidding low to win the contract and then cutting back on effort. While competition helps reduce the rent of efficient firms, it exacerbates the problem due to moral hazard. If allocative efficiency is a requirement, limiting the number of participants may be optimal. Alternatively, the same incentives can be optimally provided using inefficient allocation rules. 相似文献

A sizable proportion of United States Hispanics live in segregated communities. The rising Hispanic population in the United States and the negative association of enclave-residence with earnings have given rise to the concern that a large part of the current and future labor force, native and immigrant Hispanics, may struggle to improve social mobility and integration into the mainstream United States population. However, the causal effect of enclave-residence on earnings of Hispanics in the United States remains an open question given that previous studies have not addressed the non-random distribution of individuals into and out of enclaves. Using a longitudinal data set I address the non-random location decision of individuals to identify a causal link between enclave-residence and earnings of Hispanics. I find a much larger negative impact of enclave-residence on earnings than previous studies. However, the results also show that enclave-residence is associated with longer durations of employment. Second generation immigrant Hispanics appear to be immune from the wage penalty that is associated with enclaves. 相似文献

The objective of the study is to examine the impact of technical progress in agriculture on changes in rural poverty in Pakistan by using annual data from 1975–2011. Data is analyzed by the set of sophisticated econometric techniques i.e., cointegration theory, Granger causality test and variance decomposition, etc. The results reveal that agricultural technology indicators act as an important driver to alleviate rural poverty in Pakistan. Granger causality test indicate that causality runs from technological indicators to rural poverty but not vice versa. However, agricultural irrigated land and industry value added, both does not Granger cause rural poverty, which holds neutrality hypothesis between the variables. Variance decomposition analysis shows that among all the technological indicators, agricultural machinery in form of tractors have exerts the largest contribution to changes in rural poverty in Pakistan. The study concludes that agricultural technology indicators are closely associated with economic growth and rural poverty in Pakistan. Technology in Pakistan has a low pace but still old technology continuously contributed towards poverty reduction. The question whether idea machine is broken down or not? Still need further exploration. 相似文献

Group discussions are probably one of the most frequently used research techniques in social science. However, this popularity has still not managed to reduce the misconceptions expressed in the general literature about its use. This article is an attempt to reduce some of these misconceptions. To achieve this, the underlying characteristics of the technique are discussed, followed by an examination of the many reasons, cited by researchers, for its use. This is then followed by a discussion of its advantages and disadvantages as well as the variants to be found in practice. Finally, the article examines a number of considerations that are based on the collective experience of various researchers and which, if followed, are said to provide a better chance of success. The article concludes that, contrary to the general perception that the technique is governed largely by subjectivity, it requires its user to give careful thought and planning to the dynamic process. 相似文献

The paper investigates future exchange rate policy of the Middle East and North African (MENA) countries vis‐à‐vis the euro aimed at fostering their manufactured exports towards Euroland. The exchange rate policy is captured through three different indicators: the real effective exchange rate changes, volatility, and misalignment. The investigation is conducted for 11 sectors over the period 1970–1997. The sample includes four North African countries (Algeria, Morocco, Tunisia, Egypt) and Turkey. The results show that exchange rate management plays a crucial role in providing incentives for manufactured exports toward Euroland. The food sector is weakly responsive to real exchange rate changes while the textile sector is highly responsive. Four growing sectors (electronic, electrical, mechanical, and vehicles) were also found to be highly sensitive to exchange rate changes. The results suggest that policymakers should be more concerned with misalignment than with volatility. 相似文献

Nanotechnologies are often presented as breakthrough innovations, where technology transfer and knowledge-bridging will play a pivotal role in the industrial dynamics. This article investigates the model of knowledge transfer in the nanotechnologies in depth, by comparing it with the models of two recently emerged technologies: biotech and microelectronics. Our results show that the nanotechnology transfer model is very different from that involved in biotechnology evolution: while small–medium firms play a valuable technology-bringing role, the central function of “translating” new knowledge between public research and industry is carried by the larger firms, just as it was in the early stages of the microelectronics sector. These results suggest that specific policy initiatives to facilitate biotech's transfer are inappropriate to boost the diffusion of nanotechnology. 相似文献

Recent research has underlined the importance of external linkages for industrial clusters. Suppliers and buyers within a global value chain offer important external ties for cluster-based producers not only in terms of the distribution of physical goods, but also for knowledge flows and innovation. Globalization has intensified such value chain links, connecting geographically dispersed producers to global markets. Yet, there is limited research on how local clusters enter global chains or on ties between clusters in the developed and developing world. This study addresses this gap. It uses the case of the global surgical instrument industry to analyse connections and differences between the industry's leading production clusters in Germany and Pakistan. Global standards, low-cost competition, and advances in medical technology raise challenges for both clusters. The paper explores the responses to these challenges. It distinguishes between knowledge and production links to illustrate differentiation in each cluster, diverging trajectories and continuing ties. 相似文献
