Recent Progress on Endogeneity in Choice Modeling

We describe recent progress in several areas related to endogeneity, including: choice set formation and attention to attributes; interactions among decision-makers; respondents' strategic behavior in answering stated preference choices; models of multiple discrete/continuous choice; distributions of willingness-to-pay; and methods for handling traditionally endogenous explanatory variables.     

The relationship between institutional ownership and casino firm performance

This study examined the relationship between institutional ownership and firm performance in the casino industry from 1999–2003. Given the evidence of the endogeneity of institutional ownership in the casino industry, institutional ownership was found to be a significant and positive determinant of casino firm performance as measured by a proxy for Tobin's Q in a simultaneous equations system. This study reveals that investing institutionally in casino firms may help casino industry investors mitigate the agency problem caused by the separation of management from ownership. In addition, financial institutions tend to invest in larger casino firms with lower financial leverage.     

Ethnicity, Endogeneity, and Housing Tenure Choice

Home ownership rates for New Zealanders of European descent aged twenty five to fifty four are 16 percentage points higher than for Maori in the same age group. This article explores the relative attainment of home ownership of the two ethnic groups by estimating a series of tenure choice models and decomposing the difference in rates into endowment and residual effects. Particular attention is given to the endogeneity of current income and wealth relative to the tenure choice decision and to the methods for decomposing group mean differences. The article also applies more appropriate methods for estimating incomes and wealth than have been used in most previous studies of tenure choice. The study concludes that only a small proportion of differences in home ownership rates is explained by household endowments. It is shown that controlling for the endogeneity of income and wealth has a substantial impact on the tenure choice and decomposition results.     

Monetary Union,Trade Integration,and Business Cycles in 19th Century Europe

This paper studies the impact of monetary arrangements on trade integration and business cycle correlation in late 19th century Europe. We estimate a gravity model and show that tighter monetary integration was associated with substantially higher trade, as in recent studies using contemporary data. For instance, the Austro-Hungarian monetary union improved trade between member states by a factor of 3. To explain this, we build and estimate a simple model where greater monetary integration weakens the current account constraint by fostering business cycle co-movements.     

基于动态内生性的董事会结构与公司绩效间的跨时期相互作用

在董事会结构与公司绩效间关系的研究中,动态内生性问题通常被忽略。本文以2002-2011年410家上市公司为样本,在动态内生性的框架下,运用动态面板的System GMM估计方法,研究了董事会结构与公司综合绩效间的关系。结果表明：董事会结构与公司绩效间存在动态内生性问题,当期董事会结构与公司绩效没有显著的相关性,前期的董事会结构与公司绩效间存在显著的正相关关系,且前期公司绩效对当期董事会规模产生了显著的正向的反馈效应,但前期公司绩效并未对当期董事会的独立性产生显著影响。     

The perils of endogeneity and instrumental variables in strategy research: Understanding through simulations

In this paper we use simulations to examine how endogeneity biases the results reported by ordinary least squares (OLS) regression. In addition, we examine how instrumental variable techniques help to alleviate such bias. Our results demonstrate severe bias even at low levels of endogeneity. Our results also illustrate how instrumental variables produce unbiased coefficient estimates, but instrumental variables are associated with extremely low levels of statistical power. Finally, our simulations highlight how stronger instruments improve statistical power and that endogenous instruments can report results that are inferior to those reported by OLS regression. Based on our results, we provide a series of recommendations for scholars dealing with endogeneity. Copyright © 2013 John Wiley & Sons, Ltd.     

人力资本产权实现方式与公司绩效的内生性因素研究

随着人力资本对经济效益和公司绩效的影响越发显著,人们越发重视人力资本对公司绩效的影响。基于内生性因素视角下对人力资本产权实现方式与公司绩效的影响进行的研究表明,人力资本产权实现方式驱动公司绩效的因素主要有雇佣薪酬、股权性收益、参与权、控制权,公司绩效影响人力资本产权实现方式选择的因素则有增长机会、行业竞争程度、公司规模和生命周期等。研究进一步显示:将人力资本产权实现与公司绩效相关关系具体化,可以找出更具经济效益的人力资本产权实现方式,从而促进公司绩效的提升。     

An Empirical Assessment of Endogeneity Issues in Demand Analysis for Differentiated Products

This article explores the issue of price and expenditure endogeneity in empirical demand analysis. The analysis focuses on the U.S. carbonated soft drink market. We test the null hypothesis that price and expenditures are exogenous in the demand for carbonated soft drinks. Using an almost ideal demand system (AIDS) specification, we strongly reject exogeneity for both prices and expenditures. We find that accounting for price/expenditures endogeneity significantly impacts demand elasticity estimates. We also evaluate the implications of endogeneity issues for testing weak separability.     

On Endogeneity Bias: Some General Remarks and Correction of the ROIW Paper by Bourguignon,Ferreira, and Menéndez (2007)

This paper is a short note on the question of correcting for endogeneity bias in a regression. It also points out errors and omissions in the derivation of this bias in Bourguignon, Ferreira, and Menéndez (2007). We show that some assumptions needed for the derivation are not explicit and even under these assumptions, certain simplifications adopted are not valid. We support our points using simulation experiments.
