与国际通行的增值税制相比,我国增值税制存在着与营业税分立、非全面性、半消费型、税率繁杂、有限出口退税、重复征税等扭曲性,矫正之策是,制定《增值税法》,全面推行营业税改征增值税,全面建立完全消费型增值税,并实行增值税的统一征管。 相似文献

本文分析了广东省外贸出口与进口、FDI、出口对象国的经济增长及人民币名义汇率等影响因素的长期均衡关系,然后分析了短期中广东省外贸出口量对各影响因素波动的反应。得出结论:长期中,广东省出口额与外国收入、进口额、人民币名义汇率之间存在着正相关关系,而短期内进口额和人民币名义汇率对出口影响较大。 相似文献

This paper estimates time specific values for China's long-run equilibrium exchange rate and develops measures of the direction and extent of misalignment based on a reduced-form real effective exchange rate (REER) model. An appropriately specified long-run equilibrium model is estimated and tested following Johansen and Juselius (1990) procedures, which is then used to construct an estimated time path for long-run equilibrium exchange rate values.Unit root tests indicated that each series can be considered as I(1) and that there was one cointegrating relationship linking the RMB series with its “fundamentals” – openness, money supply, productivity and government spending – with long-run elasticities of (0.41), (0.97), (0.51) and (0.75), respectively. The estimated error-correction model of REER determination showed that during China's latest exchange rate regime (from 2005:Q3) the RMB was undervalued by an average of 6.7 percent, which is modest compared to related studies.Estimation of the associated short-run error correction model shows that the error correction term has a statistically significant value of 0.85, implying that the actual real effective exchange rates would converge relatively quickly (just over one quarter, on average) towards their long-run equilibrium level in the absence of central bank intervention. 相似文献

This paper shows the results of an exploratory analysis of the structure of a complex product category: Wine. In complex categories, a usual strategy of consumers is the partitioning of alternatives into homogeneous subsets and the sequential eliminations of subsets until a product/brand is chosen from among few homogeneous alternatives in the last subset. To identify if there is such a kind of strategy and the product attributes involved is of great interest for the retailer. After a discussion of the different modelling alternatives of the choice process, the authors provide an application of the additive trees (ADDTREE) model to explore the hierarchical structure. The ADDTREE results provide a first overview of the competitive market structure of the wine category: competition becomes more intense as the wine category is partitioned by, first, the type of wine criteria and, second, the designation of origin (DO) criteria. 相似文献

The aim of this chapter is to run through the history of marketing research applied to measuring the effectiveness of advertising and deepen in all those theories that have shed light on this aspect and have influenced subsequent theories and models. This historical review offers the opportunity of knowing the past and understanding better the present of market research applied to advertising. It is a chronological analysis to present day, which introduces the development of the explanatory models for the functioning of advertising and the theoretical and empirical contributions in this area. 相似文献

We construct a disaggregated rural economywide model with a focus on gender and immigration as well as on the allocation of time to wage work, household production activities, and housework (reproduction). We use this model to simulate the impacts of the Dominican Republic-Central American Free Trade Agreement (DR-CAFTA) on rural incomes and welfare in the Dominican Republic. We find that elimination of agricultural import tariffs hurts both agricultural and non-agricultural households, via adverse factor-market effects, but impacts vary substantially by workers’ gender and country of origin. Females and Haitian immigrants tend to fare better than Dominican males, and there are ramifications for both market and non-market activities. 相似文献

Constant proportion portfolio insurance (CPPI) allows an investor to limit downside risk while retaining some upside potential by maintaining an exposure to risky assets equal to a constant multiple of the cushion , the difference between the current portfolio value and the guaranteed amount. Whereas in diffusion models with continuous trading, this strategy has no downside risk, in real markets this risk is nonnegligible and grows with the multiplier value. We study the behavior of CPPI strategies in models where the price of the underlying portfolio may experience downward jumps. Our framework leads to analytically tractable expressions for the probability of hitting the floor, the expected loss, and the distribution of losses. This allows to measure the gap risk but also leads to a criterion for adjusting the multiplier based on the investor's risk aversion. Finally, we study the problem of hedging the downside risk of a CPPI strategy using options. The results are applied to a jump-diffusion model with parameters estimated from returns series of various assets and indices. 相似文献

Medieval bishops condemned and restricted the sale of corrodies (a type of annuity), partly on the grounds of their perceived unprofitability. The available data on the profitability of corrodies is limited and little analysed, and the episcopal condemnation of corrodies has been adopted by modern researchers. After recognising the difficulties, this paper applies an annuity pricing model to study corrody pricing. Given various assumptions, contrary to the established view, it is argued that the sale of corrodies was financially profitable for institutions. Finally, some reasons are considered for the negative attitude of contemporary and historical opinion towards the sale of corrodies. 相似文献
