International trade can affect the environment in different ways. This may justify the introduction of border measures by the importing countries. In addition to various dispositions in the GATT, GATS, TRIPs agreements, as well as in the Agreement on Agriculture, this issue is regulated by the agreements on Technical Barriers to Trade (TBT) and on the application of Sanitary and Phyto‐sanitary standards (SPS). Despite these rules, abuse of environmental arguments for protectionist reasons remains an open issue. In order to disentangle protectionism from dispositions justified on the grounds of true environmental concerns, we systematically review notifications of SPS and TBTs by importing countries at the tariff line level. Trade is considered as being potentially affected when an environmental SPS/TBT is notified on grounds of environmental concerns. Affected trade is defined as imports by countries notifying such barriers. Protectionist use of environmental barriers is likely when only a limited number of countries impose an environmental obstacle on the imports of a given product. Considering data for 2001, we find that 88 per cent of the value of world trade is in products potentially affected by such measures, while 39 per cent of the value of world imports is potentially subject to a protectionist use of such measures. Agriculture, the automobile industry, the pharmaceutical industry and many other sectors are concerned. 相似文献

According to World Trade Organization rules, countries may adopt regulations under the Agreements on Sanitary and Phyto-Sanitary (SPS) and Technical Barriers to Trade (TBT). We analyze the structure of these measures in agricultural trade. The inventory approach suggests that European countries have among the lowest coverage ratios of all OECD countries. Using a gravity equation, we also estimate their stringency. Our results suggest that they significantly reduce developing countries' exports to OECD countries, but do not affect trade between OECD members. Furthermore, European imports are more negatively influenced by SPS and TBTs than imports of other OECD countries. 相似文献

Despite the growing importance of foreign direct investment (FDI) in tourism for developing countries and its perceived developmental importance, there are few empirical impact studies. This paper explores tourism FDI and poverty alleviation through both the literature and a detailed review in The Gambia of the relative contribution of foreign versus locally owned hotels to development and poverty alleviation. Data was collected via an in-depth questionnaire with senior hotel management and through key informant interviews with tourism officials and stakeholders. The study provides empirical evidence of the relative characteristics, performance, and benefits of foreign investments, suggesting that different forms of hotel ownership have complex advantages and disadvantages for poverty alleviation. FDI was concentrated in larger, upmarket hotels, which tended to employ more staff, pay higher wages, and provide more training. However, they had a lower proportion of women employees and employment was more likely seasonal. They have more high-skilled positions, potentially offer staff mobility, but have more expatriates in management roles. Local food purchases were similar across hotel ownership types, as were local philanthropic initiatives, although there were differences of approach. Some resident foreign owners were involved in successful best practice community-linked businesses, driven by social service and environmental ethics. 相似文献

Despite its importance to economic growth, the investment behavior of firms remains poorly understood. Existing models ignore irreversibility and the opportunity to wait for new information. Even if some recent literature accounts for these two characteristics, these models ignore information costs. This paper presents a framework for the valuation of investment opportunities accounting for information costs regarding the project cash‐flows.
We develop some basic models of irreversible investment to illustrate the option‐like characteristics of investment opportunities under incomplete information. We show how optimal investment rules can be obtained using option pricing theory under incomplete information. It is possible to value real options and investment decisions using our approach in a context of incomplete information. Simulations are provided to illustrate our main results. 相似文献

Abstract Real-world evidence (RWE) provides external validity, supplementing and enhancing the randomized controlled trial data with valuable information on patient behaviors and outcomes, turning efficacy and safety results into real-world effectiveness and risks, but the use of RWE is associated with challenges. The objectives of this communication were to (1) summarize all guidance on how to conduct an RWE meta-analysis (MA) and how to develop an RWE cost-effectiveness model, (2) to describe our experience, challenges faced and solutions identified, (3) to provide recommendations on how to conduct such analyses. No formal guidelines on how to conduct an RWE MA or to develop an RWE cost-effectiveness model were identified. Using the context of non-vitamin K antagonist oral anticoagulants in stroke prevention in atrial fibrillation, we conducted an RWE MA, after having identified sources of uncertainty. We then implemented the results in an RWE cost-effectiveness model, defined as a model where all inputs come from RWE, including all parameters related to treatment effect. Based on challenges faced, our first recommendation relates to the necessity of conducting sensitivity analyses, either based on clinical or methodological considerations. Our second recommendation is the need for extensive collaboration with a wide range of experts, during the development of the analyses protocols, the implementation of the analyses and the interpretation of the results. RWE may address a number of gaps related to the treatment effect, and RWE economic evaluations for the treatment effect can provide extremely valuable insights into real-world economic value of interventions. As the increased recognition of the value of RWE could influence health technology assessment decision, and current practices, this communication supports the urgent need of more formal guidelines. 相似文献

TOURISM, TRADE AND DOMESTIC WELFARE 总被引:1,自引:0,他引:1
Abstract. Tourism has been regarded as a major source of economic growth and a source of foreign exchange. It has also been viewed as an activity that imposes costs on the host country. Such costs include increased pollution, congestion and despoliation of fragile environments, and intra-generational inequity aggravation. One aspect that has been ignored is the general equilibrium effects of tourism on other sectors in the economy. This paper presents a model that captures the interdependence between tourism and the rest of the economy, in particular agriculture and manufacturing. An important result obtained is that the tourist boom may 'immiserize' the residents. 相似文献

Developed and well regulated financial markets are usually seen as a precondition for an efficient allocation of resources and can foster long term economic growth. This paper explores the institutional determinants for financial development in the countries of the Middle East and North African (MENA) region. Institutional conditions are from the International Country Risk Guide. Panel‐econometric techniques are applied to assess the development in the banking sector and the stock market. As a main finding, institutional conditions are important in both financial segments, even after controlling for standard macroeconomic determinants and fixed effects. For the banking sector, corruption seems to be most decisive. For the stock market, the impact of corruption and law and order appear to be relevant. While per capita income and inflation do not seem to play a vital role, openness to foreign trade is quite important for all areas of financial development. Hence, overall, faster real economic integration is of key policy priority to improve financial development as a condition for higher GDP growth. Better law and enforcement practices and anti‐corruption policies are strategies to accompany this process. 相似文献
