TL;DR: A large body of empirical research has shown that social relationships and the networks these relationships constitute are influential in explaining the processes of knowledge creation, diffusion, absorption, and use.

TL;DR: The authors found that firms located in counties with higher levels of religiosity display lower degrees of risk exposure, as measured by variances in equity returns or returns on assets, and that chief executive officers are more likely to join a firm with a similar religious environment as in their previous firm when they switch employers.

TL;DR: In this article, the authors present a framework to understand how endogeneity arises and how to control for it with instrumental variables to estimate causal relations with observational data, using the Heckman two-step procedure and the STATA commands of the exposed tests and methods.
Abstract: This article offers a framework to understand how endogeneity arises and how to control for it with instrumental variables to estimate causal relations with observational data. It builds on the state-of-the-art research in applied and theoretical econometrics to highlight the importance of endogeneity and review the methods that can be used to address it with instrumental variables.The article also discusses when the Heckman two-step procedure can be used, as well as the tests, methods and assumptions that researchers should check when using instrumental variables.To ease implementation of the instrumental variables techniques, the author offers the STATA commands of the exposed tests and methods. Further, an empirical example is provided along with the utilized STATA codes. In the end, this article serves as a`toolkit' allowing scholars not only to understand whether endogeneity is present in their empirical setting, but also to assess the empirical validity of their work when using instrumental variables.

TL;DR: In this paper, the authors propose a multi-period model in which competitive arbitrageurs exploit discrepancies between the prices of two identical risky assets, traded in segmented markets, and characterize conditions under which arbitrageur take too much or too little risk.
Abstract: We propose a multi-period model in which competitive arbitrageurs exploit discrepancies between the prices of two identical risky assets, traded in segmented markets. Arbitrageurs need to collateralize separately their positions in each asset, and this implies a financial constraint limiting positions as a function of wealth. In our model, arbitrage activity benefits all investors because arbitrageurs supply liquidity to the market. However, arbitrageurs may fail to take a socially optimal level of risk, in the sense that a change in their positions may make all investors better off. We characterize conditions under which arbitrageurs take too much or too little risk.
