风险投资背景异质性与退出时机选择——基于信任视角的实证研究

退出是风险投资获得投资回报、实现投资目标的关键环节,以我国2009—2016年深圳中小板和创业板IPO公司为研究样本,分析风险投资背景异质性对其退出时机的影响,并进一步检验风险投资机构与创业企业之间的信任在其中的调节作用。研究发现：风险投资背景异质性对其退出存在显著影响,与独立风险投资相比,公司风险投资在创业企业IPO后退出企业时间更晚;无论是基于声誉的信任还是基于制度的信任,风险投资机构与创业企业之间双向的信任都会促使公司风险投资更晚退出创业企业;相对于独立风险投资,公司风险投资更晚退出企业是为了追求战略回报。研究表明创业企业可以通过提升风险投资对其信任度来维护其投资管理,而风险投资机构则可以通过提升创业企业对其信任度来加深互惠互信的合作关系。

A multiproduct Symmetric Generalized McFadden cost function

This paper introduces a flexible multiproduct cost function that permits zero values of one or more of the outputs and can impose restrictions quite easily, if not automatically satisfied, to ensure global concavity property. It satisfies linear homogeneity (in prices) property and is flexible in the output space. Thus the function is ideal for estimating, for example, economies of scope, cost complementarity, product-specific returns to scale, etc., without worrying about zero values of output(s) and extrapolations to points far from the point of approximation. As an empirical application, we use panel data (1978–1985) on 12 Finnish foundry plants to estimate technical progress, overall returns to scale, product-specific returns to scale and economies of scope.

The impact of product placement on TV-induced tourism: Korean TV dramas and Taiwanese viewers

This study examines of the ways in which Korean TV dramas affect Taiwanese consumers’ attitudes toward the locations where the dramas are filmed (onscreen locations). Previous studies have incorporated balance theory into product–character association models and have demonstrated that consumers tend to align their attitudes toward products with the valence of a character’s attitudes toward the products. Unlike previous studies, this article attempts to investigate the product–character association model in a cross-cultural setting where the ‘products’ considered are the onscreen locations. To account for the effect of similarity between Taiwanese culture and Korean culture, the concept of perceived cultural proximity is introduced into the balance-theory-based model. The results show that consumers’ parasocial relationships with a character and consumers’ attitudes toward the character are related to their attitudes toward the location. However, this relationship is significant only for those viewers with high perceived cultural proximity between Taiwan and Korea.     

上市公司业绩预告与股票收益率的经验研究

运用上市公司财务与市场数据,对业绩剧变公司的业绩预告的特点、影响因素及业绩预告对股票价格影响的实证研究发现,业绩预告披露的可能性与业绩变动、基金持股比例、公司规模等因素有关,与风险、前十大股东持股比例等因素无关;业绩预告披露、年度财务报告披露期间的异常收益率与ROE变动比率、资产规模、信息披露细致程度等因素有关。在年报披露期间,业绩预告披露与否对异常收益率有显著影响,业绩预告会在一定程度上削弱年度财务报告信息对该公司股票的利空、利好效应.     

Does High Service Quality Reduce Risk or Create Idiosyncratic Returns?

This article explores the impact of service quality on idiosyncratic returns, idiosyncratic risk (nonsystematic risk), and beta (systematic risk). Service quality was derived from the airline quality rating, and three dependent variables were calculated by the Fama–French four-factor model. The data includes 1,512 monthly records from 1997 to 2006, across 21 airlines. Multiple regression and vector autoregressive models were applied to test relationships among all, low-cost, and non-low-cost airlines. The study found that service quality has a positive impact on idiosyncratic returns in non-low-cost airlines; non-low-cost airlines are less affected by changes in the external environment.     

Impacts of short-term interest rates on stock returns and exchange rates: Empirical evidence from EAGLE countries

In this study, we estimate Bayesian vector autoregression (BVAR) and time-varying structural VAR (TVP-VAR) models for Brazil, Indonesia, Mexico and Turkey to analyze the impacts of short-term interest rates on stock prices and exchange rates considering the relationships between these variables. BVAR and TVP-VAR models’ estimations indicate that monetary policy decisions of these countries lead to capital movements as well as capital movements may create a considerable amount of variation in exchange and stock markets both in the periods of economic stability and financial crisis. We also reveal that increases in interest rates intending to prevent capital outflows may lead to decrease in stock returns, which in turn may deteriorate the real economic activity in Indonesia, while changes in short-term interest rates in Brazil, Indonesia and Turkey cannot be used as a tool to stabilize the value of their home currencies against the USD. Our study highlights the importance of formulating an optimal monetary policy framework accompanied by macro-prudential polices, which help to reach inflation target and smooth the possible variations in exchange rates and stock prices during economic crisis conditions in Brazil, Indonesia, Mexico and Turkey.     

Investor Sentiment and Stock Returns: Evidence from Turkey

This paper investigates the relation between investor sentiment and stock returns on the Istanbul Stock Exchange, employing vector autoregressive (VAR) analysis and Granger causality tests. The sample period extends from July 1997 to June 2005. In the VAR models, stock portfolio returns and investor sentiment proxies are used as endogenous variables. Two dummy variables accounting for natural and economic crises are used as exogenous variables. The analysis results suggest that, excepting shares of equity issues in aggregate issues, stock portfolio returns seem to affect all investor sentiment proxies, namely closed-end fund discount, mutual fund flows, odd-lot sales-to-purchases ratio, and repo holdings of mutual funds. Investor sentiment does not appear to forecast future stock returns; only the turnover ratio of the stock market seems to have forecasting potential.
