Product Market Competition and the Ownership Choice of Business Groups: Evidence from Korean Chaebols

This study investigates the effect of product market competition on the ownership choice of controlling shareholders in the Korean business groups known as chaebols. We find that member firms in more competitive markets have less disparity between the control and cash flow rights of controlling shareholders. The adjustment in ownership due to product market competition is implemented mainly through an adjustment in the ownership of affiliates rather than in the direct ownership of controlling shareholders. The disciplinary effect of product market competition is observed only in member firms with lower market power in their own industries. The result implies that product market competition works as a disciplinary mechanism that reduces the incentive of chaebols’ controlling shareholders to pursue the private benefits of control.     

国有资本对养老保险基金的最优划转率研究 ——基于OLG模型的比较静态分析

利用世代交叠模型（OLG模型）探讨划转国有资本与养老保险制度改革及人口结构演化的关系。假设社保基金持股不变现、从国有资本净收入中获取分红,结果显示：中、高生育率方案下,如果做实个人账户,划转率在55%~65%,就能够实现社会福利最大化和目标替代率,并兼顾年轻消费的转折点;10%的政策划转率与此仍有较大差距。为保障社会福利和替代率目标,应增加国有资本划转比例,优化制度参数,并辅以改善制度运行环境的其他措施。     

Pricing behavior of exchange traded funds

We attempt to determine whether characteristics found to be effective indicators of individual stock price performance are effective indicators of exchange traded fund (ETF) price performance. Specifically, we test the performance of investing strategies based on separately categorizing ETFs into deciles according to size, trading volume, and momentum. When analyzing the entire sample, we find that the indicators can effectively signal differences in future performance. However, the indicators appear to be indirect proxies for the types of ETFs (broad-based, sector, or international). When we isolate each type of ETF, the indicators are not as effective. The indicators are not as useful for signaling unusual stock price performance of ETFs as they have been for individual stocks. We attribute the distinctly different results found here for ETFs to the unusual characteristics of ETFs that distinguish them from individual stocks. Investing strategies that rely on these indicators for selecting individual stocks may be indirectly driven by stock-specific fundamentals. However, fundamentals are not as meaningful for stock indexes (represented by ETFs) as for individual stocks.

中国封闭式基金财富效应的实证分析——基于协整理论的分析

本文基于生命周期-持久收入假说（LC—PIH）的理论框架建立了封闭式基金财富效应估计的简约化模型,并运用上海证券交易所和深圳证券交易所的样本数据进行了实证检验。结果表明我国封闭式基金市值与社会消费品零售总额之间不仅存在长期的协整关系,而且短期内也存在弱的财富效应。因而建议稳定基金市场发展,规范基金市场秩序,以充分发挥基金市场对我国消费的引导和调控作用。     

Mutual fund flows and investors’ expectations in BRICS economies: Implications for international diversification

This paper empirically examines the relationship between different classes of mutual funds, measures of investors’ expectations and business cycle movements in the BRICS markets over the 1996Q1-2017Q3 period. Applying the Panel Vector Autoregressive (PVAR) model in a Generalized Method of Moments (GMM) setting, the results suggest a strong causal relationship between mutual fund flows and measures of investors’ future expectations. In particular, fund flows are forward-looking and assist in forecasting real economic conditions. Moreover, investors choose to invest in riskier funds when economic conditions are good, while they prefer safer options in poor economic situations. These findings have important implications for international diversification.     

Gender matters most. The impact on short‐term risk aversion following a financial crash

This paper examines how investors in an emerging market react to a domestic financial crisis. We conjecture that risk aversion increases following such events and that the effect is more pronounced among specific groups of investors. Our study makes use of a unique dataset of mutual fund investors from one of Colombia's largest stock brokers. Our results reveal that women and self‐employed individuals make the largest withdrawals from risky funds after financial crises.
