This paper utilizes a general equilibrium approach to investigate the factor returns and output effects on a regulated and unregulated sector from imposition of a rate of return on investment regulatory constraint. The results differ from those of the ‘traditional’ partial equilibrium model of the regulated firm as originally developed by Averch and Johnson (AJ). The differences are explained by the fact that the general equilibrium approach assumes the existence of efficient capital markets whereas the AJ approach does not. Introduction of the competitive capital market framework in the study of financial regulation through the general equilibrium methodology is this paper's major contribution.  相似文献

Although multiregional input–output (MRIO) databases use data from national statistical offices, the reconciliation of various data sources results in significantly altered country data. This makes it problematic to use MRIO-based footprints for national policy-making. This paper develops a potential solution using the Netherlands as case study. The method ensures that the footprint is derived from an MRIO dataset (in our case the World Input–Output Database (WIOD)) that is made consistent with Dutch National accounts data. Furthermore, usage of microdata allows us to separate re-exports at the company level. The adjustment results in a foreign footprint in 2009 that is 22% lower than the original WIOD estimates and a significantly altered country allocation. We demonstrate that already in the data preparation phase due to the treatment of re-exports and margins, large differences arise with Dutch national statistics, which may help explain the variation in footprint estimates across MRIO databases.  相似文献

The literature has not reached a consensus yet regarding the existence of sovereign creditor moral hazard. Exploiting an exceptional historical example, this paper proposes an original method to address this issue. As the corona which is observable only during a total eclipse of the sun, market-specific prices of repudiated bonds are observable only when extreme conditions segment the markets. Such very rare events allow for isolating pure country-specific bailout expectations. The paper shows that bailouts do create creditor moral hazard. Based on an impulse response analysis, the econometric results further emphasize the influence of bailout expectations in sovereign bonds valuation.  相似文献

Between 2000 and 2009, nine plant clinics in three agro-ecological areas of Bolivia (Andes, lowlands and valleys) served about 800 communities in an area roughly 300 × 100km. Over 6000 farmers consulted these clinics with 9000 queries. Many found the advice so useful that they visited the clinics repeatedly. A survey of 238 clinic users found that most adopted the clinics' recommendations. Fruit and vegetable growers who followed the clinic recommendations tended to spend less on pesticides. As for certain crops like potato, citrus and peach palm, a modest increase in pesticides helped improve the quality and quantity of the harvest. Farmers improved their incomes by following the clinics' advice. The poorest farmers enjoyed the greatest increase in income per hectare. This was the first study to explore the impact of plant clinics; future studies need to be improved, for example by obtaining baseline data and by comparing clinic users to their peers who have not used clinics.  相似文献

This study aims to answer whether and how returnee entrepreneurs’ international experience and returnee entrepreneurial firms’ international market knowledge influence these firms’ internationalization. Anchored in a framework combining an entrepreneurial and knowledge-based view, we develop a model and four hypotheses on the relations between returnee entrepreneurs’ international experience, international market knowledge, international market commitment, and level of internationalization of the returnee entrepreneurial firm. Empirical evidence of the proposed model is derived from a recent sample of Chinese returnee SMEs in knowledge-intensive and high-technology industries. The main finding is that returnee entrepreneurs’ international experience nurtures international market knowledge of returnee entrepreneurial firms, which in turn has a positive effect on these firms’ international market commitment and level of internationalization. In terms of theory, the study extends our understanding of returnee entrepreneurial firms by uncovering the role of returnee entrepreneurs’ international experience and returnee firms’ international market knowledge during their initial and early international expansion.  相似文献

This article examines the relation between 15-, 30-, 45-, and 60-day gold, silver, and copper futures, and their realized cash or delivery settle prices, for deliveries on the first, middle, and last business day (FD, MD, and LD, respectively) of the delivery month. Samples of futures prices for gold, silver, and copper, and the realized cash or delivery settle prices, based on fixed maturities for a cross-section of contracts are used, because time-series over fixed maturities are unfeasible owing to the restrictive maturity periods in these contracts. This study contrasts with similar studies for forwards, which are not hampered by this problem (e.g., Baillie and Bollerslev in 1989), studies that use contemporaneous time-series of futures and cash prices to obtain optimal hedge ratios (e.g., Ghosh and Clayton in 1996), and studies that examine for parity between different futures prices (e.g., Franses and Kofman in 1991). Near-term gold, closest to delivery silver and all copper futures (the latter only with settle prices at delivery) are good predictors of the future cash price, except for silver and copper deliveries on the last day of delivery months. These results are consistent with previous studies on short-term cash (Ma in 1985) and futures (Ma and Soenen in 1988) parity between gold and silver, and with Gross's (1988) results for copper. The longer-term gold (45- and 60-day) and silver (30-, 45-, and 60-day) futures reject an unbiased expectations hypothesis. This result is consistent with Leistikow (1990) because cash prices respond less than futures prices in these instances.  相似文献

This study is about the influence of integration and coordination of organisational mechanisms on the effectiveness of the process of product development by cross-functional teams. The sample consists of 50 cross-national Concurrent Engineering (CE) project teams, from companies in Australia, Canada, Denmark, Finland, UK, and USA, in the technology intensive industries of aerospace, automobile, chemical, computer, electronics, shipbuilding, and telecommunications. The study offers a diagnostic tool which measures the effectiveness of the Concurrent Engineering team's process in terms of the behaviours and attitudes of the engineering/R&D and manufacturing representatives on the product development team: (a) two-way communication, (b) overlapping problems-solving, (c) readiness to use uncertain and ambiguous information released by team counterparts for decision-making, and (d) readiness to release uncertain and ambiguous information to team counterparts. The findings of the study are that integration mechanisms, such as team-based rewards and job rotation, and coordination mechanisms, such as project structure and information technology, and project leader's management style, support an effective team process, and overcome the negative effect of geographic distance and time-difference in cross-national teams. In addition, there are interesting implications for organisational learning in the practice of Concurrent Engineering for product development, and of the implications of these findings for practice and future research.  相似文献

En numerosos estudios se han investigado los efectos de las remesas sobre los resultados laborales, generalmente con datos de nivel microeconómico. Los pocos estudios en que se han utilizado datos de nivel macroeconómico adolecen de un sesgo de endogeneidad por la inclusión de las remesas en sus estimaciones. En la presente investigación tratamos de colmar esta laguna analizando el sesgo de endogeneidad mediante un estimador del sistema MGM (método generalizado de momentos) con datos de panel de los Estados mexicanos. Las principales conclusiones son que las remesas aumentan las tasas de actividad y reducen la mediana de horas trabajadas, el empleo crítico y la duración del desempleo.  相似文献
