宪政视野下我国税收立法权制度之完善

税收立法权问题是税法基础理论中的一个重要问题。税收是政府存在的根据,税收立法权的出现是民主宪政的根据,税收立法权的配置与协调是税收宪政的核心和主题。本文从宪政的视角深入剖析了当前我国税收立法权(横向立法和纵向立法)存在的主要问题,从完善税收立法权体系、提高税收立法权民主化水平的角度提出完善我国税收立法的系列建议。     

Fashion retail forecasting by evolutionary neural networks

Recent literature on nonlinear models has shown that neural networks are versatile tools for forecasting. However, the search for an ideal network structure is a complex task. Evolutionary computation is a promising global search approach for feature and model selection. In this paper, an evolutionary computation approach is proposed in searching for the ideal network structure for a forecasting system. Two years’ apparel sales data are used in the analysis. The optimized neural networks structure for the forecasting of apparel sales is developed. The performances of the models are compared with the basic fully connected neural networks and the traditional forecasting models. We find that the proposed algorithms are useful for fashion retail forecasting, and the performance of it is better than the traditional SARIMA model for products with features of low demand uncertainty and weak seasonal trends. It is applicable for fashion retailers to produce short-term retail forecasting for apparels, which share these features.     

Do converters facilitate the transition to a new incompatible technology? A dynamic analysis of converters

This paper analyzes the process of transition in standards between incompatible technologies when converters are available. Contrary to a common presumption that converters facilitate the transition from an old technology to an otherwise incompatible new technology, I find circumstances in which the possibility of transition is blockaded by the existence of converters. In the welfare analysis of converters, a distinction is made between ex ante and ex post efficiency effects. Finally, I also analyze the equilibrium behavior in the provision of converters and compare it to the socially optimal outcome.     

Differences in Factor Structures between U.S. Multinational and Domestic Corporations: Evidence from Bilinear Paradigm Tests

This research investigates the differences in factor structure between U.S. multinational and domestic corporations. We use a multifactor return generating process and investigate whether the constraints imposed by the arbitrage pricing theory are upheld. Our results indicate and domestic corporations are not significantly different. It does appear, however, that there are different prices attached to the risk of U.S. multinational and domestic firms.     

It's Not All Relative: The Effects of Mental and Physical Positioning of Comparative Prices on Absolute versus Relative Discount Assessment

In the context of three experiments, the authors examine the manner in which consumers compare a sale price to an explicit reference value. They find that a comparison of sale price to regular price may be more likely to involve an absolute (dollar amount) assessment, whereas a comparison of sale price to a competitor's price may be more likely to involve a relative (percent) assessment. The authors also find that vertical (i.e., columnar) placement of prices may result in a greater tendency to estimate discounts in relative terms. Conversely, horizontal (i.e., side-by-side) placement may result in a greater tendency to compute absolute numerical difference. The results provide important implications for retail managers in terms of framing and communicating price discounts.
