Developing countries pay substantially higher transportation costs than developed nations, which leads to less trade and perhaps lower incomes. This paper investigates price discrimination in the shipping industry and the role it plays in determining transportation costs. In the presence of market power, shipping prices depend on the demand characteristics of goods being traded. We show theoretically and estimate empirically that ocean cargo carriers charge higher prices when transporting goods with higher product prices, lower import demand elasticities, and higher tariffs, and when facing fewer competitors on a trade route. These characteristics explain more variation in shipping prices than do conventional proxies such as distance, and significantly contribute to the higher shipping prices facing the developing world. A simple back of the envelope calculation suggests that eliminating market power in shipping would boost trade volumes by 5.9% (for the US) to 15.2% (for Latin America). Our findings are also important for evaluating the impact of tariff liberalization. Cargo carriers decrease shipping prices by 1–2% for every 1% reduction in tariffs. 相似文献

The impact of scale effects on the prevailing internet-based banking model in the US 总被引:1,自引:1,他引:0
Internet-based banks use a technology-intensive production process that may benefit from scale effects as they grow larger.
This article analyzes whether the predominant Internet-primary bank in the USA generates technology-based economies of scale
in the period 2002–2010. There is evidence of both favorable and adverse technology-based scale effects. As the leading Internet-primary
bank gets larger, the financial performance gap with traditional banks shrinks while some of its critical competitive advantages
wear down. The results suggest that unless the prevailing Internet-primary bank preserves the distinctive advantages of the
Internet-based business model as it improves financial performance, it might end up converging with its branching competitors. 相似文献

Financial institutions suffered large trading losses during the 2007–2009 global financial crisis. These losses cast doubt on the effectiveness of regulations and risk management systems based on a single Value-at-Risk (VaR) constraint. While some researchers have recommended using Conditional Value-at-Risk (CVaR) to control tail risk, VaR remains popular among practitioners and regulators. Accordingly, our paper examines the effectiveness of multiple VaR constraints in controlling CVaR. Under certain conditions, we theoretically show that they are more effective than a single VaR constraint. Furthermore, we numerically find that the maximum CVaR permitted by the constraints is notably smaller than with a single constraint. These results suggest that regulations and risk management systems based on multiple VaR constraints are more effective in reducing tail risk than those based on a single VaR constraint. 相似文献

Das et al. (2010) develop a model where an investor divides his or her wealth among mental accounts with motives such as retirement and bequest. Nevertheless, the investor ends up selecting portfolios within mental accounts and an aggregate portfolio that lie on the mean–variance frontier. Importantly, they assume that the investor only faces portfolio risk. In practice, however, many individuals also face background risk. Accordingly, our paper expands upon theirs by considering the case where the investor faces background risk. Our contribution is threefold. First, we provide an analytical characterization of the existence and composition of the optimal portfolios within accounts and the aggregate portfolio. Second, we show that these portfolios lie away from the mean–variance frontier under fairly general conditions. Third, we find that the composition and location of such portfolios can differ notably from those of portfolios on the mean–variance frontier. 相似文献

The paper investigates the efficient frontier and capital market line for the Portuguese stock market before and after the Global Financial Crisis. The efficient frontier and capital market line shift to positions that offer investors better opportunities as we move from 2000‐2008 to 2009–2015. 相似文献

The theory of constraints (TOC) proposes that, when production is bounded by a single bottleneck, the best product mix heuristic is to select products based on their ratio of throughput per constraint use. This, however, is not true for cases when production is limited to integer quantities of final products. Four facts that go against current thought in the TOC literature are demonstrated in this paper. For example, there are cases in which the optimum product mix includes products with the lowest product margin and the lowest ratio of throughput per constraint time, simultaneously violating the margin heuristic and the TOC-derived heuristic. Such failures are due to the non-polynomial completeness (NP-completeness) of the product-mix decision problem, also demonstrated here. 相似文献

This paper looks at the question of whether subsistence level/indigenous people place a value on the preservation of ecosystems independent of direct impacts of environmental change, such as impacts on their production activities. The economics literature generally suggests that non-use values don't exist among the poor and in the informal sector of the economy. We examine this issue through a choice modeling experiment. A survey was conducted of rainforest communities who live on the banks of the Amazon River (Rio Solimões), in the vicinity of proposed oil and gas pipelines. The data were analyzed in the choice modeling framework, revealing relatively high amounts of compensation that were necessary in order to accept the potential ecosystem damages associated with oil transport, even if the people were completely compensated for direct damages such as loss of access to productive resources. These results suggest that environmental quality is important for its own sake, a result that is very different from the implicit assumption among many economists. 相似文献
