Using panel data for the years 2006–2015, this study empirically investigates the effect of rule of law as an institution on Bangladesh's exports to 28 European Union countries (EU28) based on gravity model analysis. Two-step econometric results suggest that institutional rule of law is strongly associated with Bangladesh's exports, and institutional quality provides evidence of this significant effect. Furthermore, exports of Bangladesh are driven by economic size, market size, and the real exchange rate as well as rule of law. These results are suggestive of an important joint role for both trade and institutions in the long run.  相似文献

This paper aims to investigate the impacts of different sources of innovation funding on company performances in the context of an emerging economy. Brazilian software companies are selected as a case for this investigation. Data – related to the types of funding support received and eight types of company performances measured in binary scales – was collected through an online survey from 188 companies located across Brazil. A multivariate probit model was estimated to assess the impacts of different funding schemes on company performances – controlling for other confounding effects. The findings confirmed the critical importance of public innovation funding, and revealed that companies that: (1) Used public funds were more likely to become nationally competitive; (2) Used loans from commercial banks were less likely to become nationally and internationally competitive; (3) Reinvested revenues were more likely to gain market share, and help in increasing the number of employees; (4) Not aware of public funding schemes were less likely to invest on research, development, and innovation. The overall findings suggest the positive impacts of innovation funds on company performance. They can serve as a policy guide to develop targeted performance strategy to determine which funding scheme would be effective to foster what outcomes.  相似文献

Bangladesh has been suffering from rampant food adulteration for the last few decades. Dishonest businessmen use formalin illegally as preservative to prevent spoilage and increase shelf‐life of fish. Prolonged consumption of formalin adulterated fish may cause serious health hazards (i.e. cancers) which lead to increased morbidity and mortality. The aim of the review was to examine the extent and magnitude of illegal formalin treatment in fish sold in domestic markets of Bangladesh. A systematic review was conducted using conventional databases and non‐conventional approaches to identify the relevant studies. Out of nine studies, eight confirmed the presence of formalin in fish collected from the markets of four main cities. Large and imported fishes were found to be mainly affected. Formalin adulterated fish was reported in seven studies. The fish were tested using a locally developed kit, and the amount of formalin treated fish ranged between 0.5 and 50%. Two other studies used the spectrophotometric method and reported specific formalin levels. The study conducted in Dhaka found mean levels of formalin to be 402.35 mg/kg in imported fishes and 118.60 mg/kg in local fishes which were much higher than the WHO recommended levels. In another study conducted in Mymensingh, formalin levels ranged between 1.4 and 7.3 mg/kg in both marketed and freshly caught pond fishes. The use of accurate, simple, specific and sensitive techniques is therefore highly recommended. The government and other agencies should address the issue as a priority basis by formulating effective policies and programs to safeguard the health of the public.  相似文献

We use newly constructed data to model and measure agricultural productivity growth and the returns to public agricultural research conducted in Uruguay over the period 1961–2010. We pay attention specifically to the role of levy‐based funding under INIA, which was established in 1990. Our results indicate that the creation of INIA was associated with a revitalization of funding for agricultural R&D in Uruguay, which spurred sustained growth in agricultural productivity during the past two decades when productivity growth was stagnating in many other countries. The econometric results were somewhat sensitive to specification choices. The preferred model includes two other variables with common trends, a time‐trend variable and a proxy for private research impacts, as well as a variable representing the stock of public agricultural knowledge that entailed a lag distribution with a peak impact at year 24 of the 25‐year lag. It implies a marginal benefit‐cost ratio of 48.2, using a real discount rate of 5 per cent per annum and a modified internal rate of return of 24 per cent per annum. The benefit‐cost ratio varied significantly across models with different lag structures or that omitted the trend or the private research variable, but across the same models, the modified internal rate of return was very stable, ranging from 23 per cent per annum to 27 per cent per annum. These results suggest that the revitalized investment in research spending under INIA has been very profitable for Uruguay and that a greater rate of investment would have been justified.  相似文献

Environmental and Resource Economics is one of the premier journals in the field of environmental economics. It was established with an aspiration to focus more on applied and policy relevant research compared to other established journals, and to establish better channels of communication and collaboration between researchers from Europe and other parts of the world. We present a text based exploratory analysis of 1630 articles published in the Journal from 1991 to 2015 that suggests the Journal has been somewhat successful in meeting both these aims. Perhaps more importantly, it shows the Journal continues to progress toward these goals. The European authors are the largest contributors to the Journal, which is in contrast to other prominent journals (such as Journal of Environmental Economics and Management and Ecological Economics). And while most of the collaboration has occurred within this geographic region (e.g., European authors collaborated with other European authors more frequently), this trend appears to be changing as the proportion of articles written by international collaborators is gradually increasing. Topic analysis reveals that almost all of the articles could be grouped under applied and/or policy relevant topics, and almost two-thirds of the articles are empirical in nature, which suggest that the journal has been able to fulfil both of its commitments. We also investigate trends in research foci over the last 25 years and what kind of research gaps can be discerned.  相似文献

This study investigates how the additional capital and liquidity requirements of Basel III would increase the resilience of banks. In particular, using panel data from 2007 to 2014, we examine the resilience of banks in the BRICS economies. Our results suggest that a 10% increase in capital adequacy ratio (CAR), Tier 1 capital ratio (TRA), and leverage ratio (LEV), the resilience (as measured by Z-Score of banks) increases by about 2.18, 0.89 and 1.31%, respectively. Similarly, for a 100% increase in liquidity coverage ratio (LCR), the resilience of banks increases by 0.51%, 1.10% and 1.19%, respectively, in the models associated with CAR, TRA, and LEV. Hence, our findings suggest that the CAR is robust to increase the resilience of banks. Our study also reveals that the LCR and LEV are the most effective to increase the resilience of banks if implemented simultaneously. We also find that the stage of economic development does not matter in formulating policies for the BRICS economies, and finally, we provide empirical evidence that economy-wide risk, such as a financial crisis, does not affect the resilience of banks and it influences the resilience of banks in the BRICS economies in the same way before and after the crisis.  相似文献

Natural gas is the key non-renewable source of energy for a low-carbon economy. The research applies heterogeneous panel techniques to investigate the impact of natural gas consumption on economic growth across a panel of top 15 natural gas consumers of the developing world. We establish long-run dynamics with cross-sectional dependence and heterogeneity across the sample countries. The long-run output elasticities suggest that the natural gas consumption and trade variables have significant positive effect on the output in a panel of developing economies. Further, we establish feedback relationship among gas consumption, output and trade in the short-run. Given the significance of natural gas as the low-emission source of energy, we suggest governments and policy advisers of these major natural gas consumers to focus on developing pipeline infrastructure for adequate supply, reforming natural gas sector with a competitive price structure to combat excess demand in individual natural gas market. With trade integration, majority of these countries need to incorporate these initiatives to improve the technologies such as combined cycle power plant technology and value-added chemical production technology to achieve sustainable economic growth.  相似文献

This paper estimates values for a few important parameters related to the Atlantic salmon market in Canada. Included among the estimated parameters are income and price elasticities of demand. Many economists are currently engaged in the study of economic feasibility of farmed Atlantic salmon in Canada. In these studies forecasts of demand for Atlantic salmon play a crucial role. Since there are no serious studies on relevant elasticity estimates, the researchers have so far relied on extrapolations of historical time series data on demand (see, for example, Marine Science Research Laboratory (198O), Ridler (1983)). In this study we have formulated and estimated demand equations for Atlantic salmon using Canadian data covering the period between 1955 and 1981. We have found a very high value for both price and income elasticities of demand. High elasticity values have interesting implications for salmon farming. The domestic market can absorb additional supplies for Atlantic salmon. A high price elasticity guarantees that there is scope for salmon fishermen to increase their revenue by selling a higher volume in the Canadian market. The value of income elasticity suggests that Atlantic salmon is a strongly superior good. Various pressure groups in Canada and elsewhere have been claiming that Atlantic salmon is an endangered species and restrictions on catches must be imposed to save the species from total extinction. Implications of such controls have been analyzed in the light of the calculated value of the elasticities. Cet article fait une estimation de valeurs pour quelques paramètres importants reiatifs à la vente du saumon de l'Atlantique au Canada. Re-venus et élasticité des prix à la demands sont inclus parmi les paramétres étudiés. Un certain nombre d'économistes étudient en ce moment l'-aspect économique de I'implantation d'élevages de saumon de l'Atlantique au Canada. Dans ces études les previsions portant sur la demande jop-uent un rolê-clé. Etant donné qu'il n'y a pas d'études sérieuses sur les estimations d'élasticité, les chercheurs se sont appuyésA jusqu'ici sur des extrapolations à partir de séries de données historiques sur la demande. Dans cette étude nous avons formulé et estimé des équations de demande pour 1e saumon de l'Atlantique qui utilisent des données canadi-ennes entre 1955 et 1981, Nous avons trouvé une très naute valeur pour l'éasticitéà la fois des pris et des revenus. La haute élasticité des valeurs a des implications intáressantes pour l'élevage du saumon. Le marché domestique peut aisément absorber une quantité supplémentalre de saumons. Une élasticité dans la gamine élevée des prix permet de garan-tir aux éleveurs de saumon une augmentation de leurs revenus par la vente d'un volume accru sur le marché canadien. La valeur de l'élasticité du revenu suggère que le saumon de l'Atlantique est une denrée su-périeure et qu'avec une augmentation du revenu réél per capita, la demande domestique augmentera à un rythme plus rapide. Plusieurs groupes de pression au Canada et ailleurs soutiennent que le saumon atlantique est une espèce en danger et que des restrictions sur les prises doivent Ctre imposées pour sauver ces espèces d'une extinction totale. Les implications de ce genre de contrôle ont áté ana-lysées à la lumière de la valeur calculée ces élasticités.  相似文献

This study examines the impact of improvements in institutional oversight specifically for compliance with International Financial Reporting Standards on accrual quality in Europe. The sample comprises 9339 firm‐year observations from a treatment sample of three European countries that had either non‐existent or relatively weak institutional oversight systems at the start of the sample period 2006–2010 but improved oversight systems thereafter, and a benchmark sample of six other European countries that had institutional oversight systems from the start of this sample period. After controlling for legal system, rule of law and other variables, we find incremental improvement in accrual quality in the treatment sample relative to the benchmark sample from the pre‐enforcement period 2006–2007 to the enforcement period 2008–2010. The results suggest that institutional oversight has an incrementally positive impact on accrual quality over and above that attributable to legal system, rule of law and other variables. The results are robust to different measures of accrual quality, alternative enforcement proxy and alternative samples.  相似文献
