Does corporate diversification create value in emerging markets? New evidence from Chile

Using a sample of 85 Chilean firms listed in the Santiago Stock Exchange from 2005 to 2013, we analyze the impact of corporate diversification on firm value. We consider voting rights of the main shareholder and institutional investors’ influence on firm value. We report firm‐value destruction for diversified firms. Regarding ownership concentration, we report a negative relation between the largest shareholder ownership and firm value. Separation between voting rights and cash flows rights of this shareholder is negatively related to firm value. While Pension Fund Administrators (AFP) mitigate firm value destruction in diversified firms, other institutional investors do not play an active role in controlling value destruction. Finally, if the largest owner is a family, we report firm‐value creation in diversified firms. Copyright © 2016 ASAC. Published by John Wiley & Sons, Ltd.     

Concentration behavior of the penalized least squares estimator

Consider the standard nonparametric regression model and take as estimator the penalized least squares function. In this article, we study the trade‐off between closeness to the true function and complexity penalization of the estimator, where complexity is described by a seminorm on a class of functions. First, we present an exponential concentration inequality revealing the concentration behavior of the trade‐off of the penalized least squares estimator around a nonrandom quantity, where such quantity depends on the problem under consideration. Then, under some conditions and for the proper choice of the tuning parameter, we obtain bounds for this nonrandom quantity. We illustrate our results with some examples that include the smoothing splines estimator.     

The effect of place attachment of geographical indication agricultural products on repurchase intention

[Objective] This study aims to investigate how place attachment and the quality of experience affect consumers' intention to repurchase Geographical Indication (GI) agricultural products. [Methodology] Based on the special functional value and symbolic meaning of GI agricultural products, we constructed a five-dimensional model of place attachment for GI agricultural products consumers. Expanding on the original two-dimensional place attachment model, we introduced three connection concepts: nature, society, and emotion. We also combined this model with the quality of experience model and consumer purchase intention model to form a research model of repurchase intention for GI agricultural products. A questionnaire survey was used to collect data (n = 340), and a partial least squares structural equation model was used to test the empirical evidence. [Research results] (1) Place attachment to Geographical Indication agricultural products significantly affects the quality of experience. (2) Quality of experience significantly affects consumer trust and repurchase intention. (3) Consumer trust significantly affects repurchase intention. (4) There is a mediating effect of experience quality between place attachment and repurchase intention; there is a mediating effect of trust in the relationship between quality of experience and repurchase intention. (5) There is a chain mediating effect of “place attachment→quality of experience→consumer trust→repurchase intention” in the model.     

Market structure and profitability in the international tourist hotel industry

This paper adopts Hsiao (1986) panel data techniques, with metropolitan-level panel data from Taiwan, to examine how the market structures of various related service markets and hotels’ locations affect hotels’ profitability. The empirical results indicate that: (1) market concentration in rooms could significantly improve international tourist hotels’ profitability, while concentration in the food and beverage markets have positive but insignificant effects, and (2) the locations of the international tourist hotels significantly affect their profitability.

论LLSV法律来源论的缺陷性

拉普特等人用数据来表明,法律来源于普通法系国家比法律来源于大陆法系国家特别是法国大陆法系国家能更好地保护投资者,而德国大陆法系国家和斯堪的纳维亚国家则介于这二者之间。公司所有权的集中程度在他们的研究中被认为是对投资者保护差的一种适应性反映。在本文,我们用中国和其他国家的证据来说明政治经济因素比法律来源论能更好地解释在中国的转型经济中对小股东保护差的原因。我们认为中国上市公司所有权非常集中的原因是政府决策的直接结果,也认为政府控制绝大部分上市公司在某种程度上减弱了对小股东的保护。

外资进入对本土企业风险承担的影响：资本逐利还是风险规避

外资自由化作为我国资本市场开放的重要内容,在促进境内外资本要素互联互通的同时,也深刻影响着微观企业行为。以我国2007—2017年A股上市公司作为研究样本,实证检验外资进入对我国本土企业风险承担的影响。研究发现：外资进入能够显著提升企业的风险承担水平。进一步地,外资进入对企业风险承担的促进效应在融资约束严重、股权集中度更高和市场化进程缓慢地区的企业中更加显著。此外,在不同资本市场开放水平,外资进入对企业风险承担的作用存在明显差异。
