This paper investigates how tariff liberalization has affected exporting at the product‐destination level in emerging countries. We use a highly disaggregated (six‐digit level of the harmonized system—HS—classification) bilateral measure of market access to compare tariffs applied in 1996 and 2006, which includes the timing of the Uruguay Round and episodes of bilateral liberalization. Our econometric estimations consider impacts of tariff cuts on three components of the trade margins: extensive margin of entry (new trade relationships at the product‐destination level), extensive margin of exit (disappearance of existing relationships) and intensive margin of trade (deepening existing relationships). Our main estimates indicate that a reduction of bilateral applied tariffs of 1 percentage point increases the extensive margin of entry by 0.1% and the intensive one by 2.09%, while it reduces the extensive margin of exit by 0.25%. 相似文献

Following a growing concern among investors about the quality of hedge fund index return data, this paper addresses the question of whether designing hedge fund indices that fulfil the usual requirements (in particular representative and investable) is or not a feasible task, given a variety of features that are specific to that industry. To test whether or not investability should necessarily come at the cost of representativity, we use a well‐known methodology in the asset pricing literature based on the concept of factor replicating portfolios. Our results suggest that it is actually possible to construct representative indices based on a limited number of funds that are open to new investments, except perhaps in the case of equity market neutral strategies, provided that: i) these funds are suitably selected and ii) a portfolio is constructed with the objective of replicating the common trend in hedge fund returns for a given strategy. A range of robustness tests are performed that show that high correlation of the factor replicating portfolios with the common factor of returns for each strategy is remarkably stable with respect to modifying the number of funds in the replicating portfolio or changing the frequency of rebalancing. 相似文献

Public Social Spending in Africa: Do the Poor Benefit? 总被引:3,自引:0,他引:3

Education and health care are basic services essential in anyeffort to combat poverty and are often subsidized with publicfunds to help achieve that purpose. This paper examines theeffectiveness of public social spending on education and healthcare in several African countries and finds that these programsfavor not the poor, but those who are better-off. It concludesthat this targeting problem cannot be solved simply by adjustingthe subsidy program. The constraints that prevent the poor fromtaking advantage of these services must also be addressed ifthe public subsidies are to be effective. 相似文献

The view that macroeconomic adjustment disproportionately hurtsthe poor in Africa has become commonplace. The popular mediaand the nongovernmental aid community frequently express thisview in critiques of Bankfunded economic reform programs. Yetthe evidence on which the claim has been based is flimsy andanecdotal. The emergence of more convincing data, from detailedhousehold surveys in Africa, provides an opportunity to setthe record straight. The evidence from six African countries reviewed in this articledemonstrates that poverty was more likely to decline in thosethat improved their macroeconomic balances than in those thatdid not. The critical factor is economic growth: the economygrew more rapidly and poverty declined faster in countries thatimproved macroeconomic balances, depreciating the real effectiveexchange rate. Changes in the real exchange rate also immediatelyand favorably affected rural incomes, benefiting the poor bothdirectly and indirectly. But the findings also highlighted threecauses for policy concern. First, many African governments haveyet to display a real commitment to macroeconomic reform; second,the poorest of the poor have not benefited from recent growthin some countries; and, third, the prospects for the poor arenot rosy unless there is more investment in human capital andbetter targeting of social spending. 相似文献

This paper explores a model of group membership formation in which agents decide to join or not multiple social groups. The membership formation process induces a bipartite graph structure with social groups listed on one side and agents listed on the other side. Among members of multiple social groups, we consider two decisive types of agents: the grand star and the mini star. The former type is the unique agent in a society who participates in all social groups. The latter type includes agents who participate in more than one, but not all, social groups such that every social group pair has one and only one common member. We analyze the efficiency and stability conditions of group membership formation, and we establish sufficient conditions under which a connected graph that contains either a grand star or a set of mini stars becomes the unique strongly efficient and stable graph. 相似文献

The modalities of negotiation on market access for agricultural and non‐agricultural products are an important item of the Doha Development Agenda. The dispersion of tariffs remains very large, translating into sizeable economic distortions. In particular, tariff peaks are numerous and highly protective. This is why the choice of a formula of reduction in tariffs is a sensitive issue. Using the MAcMaps database, we apply various formulas excluding or including peaks at the most detailed level of information on tariffs, considering preferential schemes conceded so far. The resulting changes in tariffs are introduced in a CGE exercise using Mirage . We find that trade and welfare gains are halved when excluding peaks from the negotiations. 相似文献
