我国投资率与消费率之间变动规律分析

投资率与消费率之间变动关系在工业化进程中会呈现出一般规律性。基于此,本文首先提出经济发展进程中投资率与消费率之间存在什么样的变化规律;接着以实际数据检验改革开发以来我国投资率和消费率之变动现象是否服从投资率与消费率变动的一般规律。结果发现二者基本吻合。但是我国投资率和消费率变化规律又具有自身特点：偏高的投资率和过低的消费率。事实证明,这种现象对我国经济长期健康发展不利,必须采取一定措施,完善投资和消费的比例关系。     

内外资企业所得税分设存在的主要问题及改革选择

近年来,统一内外资企业所得税的呼声越来越高,这一问题解决得好坏关系到内资企业的生存与发展。我国现行内外资企业所得税分设的税制模式是在特定的历史条件下形成的,经过10多年的运行,曾经促进了我国经济的快速发展。但是这种企业所得税制度也有其不足,尤其是我国加入世界贸易组织后,随着经济环境的变化,这种税制暴露的问题日益突出。因此,必须对我国现行的企业所得税制度进行改革,以适应经济的发展。     

Development Regimes in the City Fringe: The Case of Discover Islington,London

There is a growing recognition of the importance of inter-organisational collaborations, or partnerships, for tourism development at various geographical and sectoral levels. Academic studies of the phenomenon are, in part, a reflection of the increasing number and forms of partnership arrangements being established in a range of settings to develop tourism. This paper examines a particular case of inter-organisational collaboration for local tourism development for the London inner city fringe. Established in 1991, Discover Islington provides an illustration of an agency involving representation from diverse stakeholders with an interest in tourism within a single administrative district. The agency has been innovative in its approach to local tourism development in the inner city fringe, but it is confronted by issues that may affect its longer-term viability. The perspectives and experiences of the partners represented on the Board of Discover Islington are pertinent to the study of comparable collaborative arrangements for local tourism development in other urban fringe contexts. The analysis is based on interviews with Board members and their policy and strategy documents within a theoretical framework that draws on regime theory. Implications for other inner city fringe tourism development partnerships are offered in the conclusion of this paper.     

Trust or not: Heuristics for making trust-based choices in HR management

The present two studies examine how the participants (i.e., 150 managers) make trust-based employee selection in hypothetical situations, based on five cues of trustworthiness derived from previous surveys. In Study 1, each executive participant is presented with a pair of candidates with different cue profiles so that the choice would favor one of them based upon each of the four following heuristics: Franklin's rule, likelihood expectancy, take-the-best (TTB), and minimum requirement (MR). Study 2 adopting a within-subject design jointly compares the four heuristics. The results show that simple heuristics (MR and TTB) outperform the more complex strategies (Franklin's rule and likelihood expectancy) in their predictive accuracy. The MR heuristic, a heuristic tallying the frequency of passes against a set of minimal rather than optimal or satisfactory requirements, performs even better than the TTB heuristic, particularly when the number of the cues identified as MRs is small.     

Credit Crunch and Target Capital Structure: Empirical Studies Based on Natural Experimentin China

Abstract:

Data from China’s credit crunch, which started in 2007, is utilized to establish a natural experiment to investigate the impact of the credit crunch on target capital structures. The sample consists of 1,128 listed companies in China during the period 2000–2011. The interest-bearing debt to total assets ratio is used as a representative indicator for capital structures. The results indicate that the credit crunch was associated with a decrease in the target debt ratios for all listed companies. Small firms, privately owned enterprises, and firms with weak mortgage capabilities responded more sensitively to the credit crunch by showing a substantial decrease in target debt ratios.     

“I just like the stock”: The role of Reddit sentiment in the GameStop share rally

This paper investigates the role played by the social media platform Reddit in the events around the GameStop (GME) share rally in early 2021. In particular, we analyze the impact of discussions on the r/WallStreetBets subreddit on the price dynamics of the American online retailer GameStop. We customize a sentiment analysis dictionary for Reddit platform users based on the Valence Aware Dictionary and Sentiment Reasoner (VADER) sentiment analysis package and perform textual analysis on 10.8 million comments. The analysis of the relationships between Reddit sentiments and 1-, 5-, 10-, and 30-min GameStop returns contribute to the growing body of literature on “meme stocks” and the impact of discussions on investment forums on intraday stock price movements.

Liquidity,default, taxes,and yields on municipal bonds

We examine the effects of liquidity, default and personal taxes on the relative yields of Treasuries and municipals using a generalized model with liquidity risk. The municipal yield model includes liquidity as a state factor. Using a unique transaction dataset, we estimate the liquidity risk of municipals and its effect on bond yields. Empirical evidence shows that municipal bond yields are strongly affected by all three factors. The effects of default and liquidity risk on municipal yields increase with maturity and credit risk. Liquidity premium accounts for about 9–13% of municipal yields for AAA bonds, 9–15% for AA/A bonds and 8–19% for BBB bonds. A substantial portion of the maturity spread between long- and short-maturity municipal bonds is attributed to the liquidity premium. Ignoring the liquidity risk effect thus results in a severe underestimation of municipal bond yields. Conditional on the effects of default and liquidity risk, we obtain implicit tax rates very close to the statutory tax rates of high-income individuals and institutional investors. Furthermore, these implicit income tax rates are quite stable across bonds of different maturities. Results show that including liquidity risk in the municipal bond pricing model helps explain the muni puzzle.
