Abstract
This paper uses biographical information of executives and directors of REITs in the US to show whether, and through what channels, top executives of REITs are influenced by their social peers when determining capital structure risk control strategies, especially in critical periods. Our focus is on the period of the 2007–2009 Financial Crisis. We find that peer influence through past employment and sharing activities significantly facilitate peer learning in making decisions on debt maturity extension, but does not affect leverage reduction. We find that being educated from the same school carries some effects on leverage reduction, possibly via its influence on managers’ personal traits. However, concurrent employment does not play a role in determining either of the strategies. We further verify the existence of influence of social network in decision making of REITs in 2015 in preparation for a boom at the beginning of the up-market. Hence, our study highlights the strength of peer connections in clarifying possible sources of herding in REITs decisions.

Notes
Note that our data source is different from the SNL Financial used in Pavlov et al. (2018); some data are not available in our study.
As mentioned in the data section, we normalize the actual centrality values by transforming them to the percentile ranks, i.e. ranging from 0 to 1.
We also test the network effects in the “normal” years 2012, 2013, and 2014, which are after the Global Financial Crisis and before year 2015 when the market started rising again. We find that the results of network effects are comparable to that of years 2006 and 2015 but are less economically significant, indicating that network effects tend to be stronger during “abnormal” periods, such as times of preparation for crisis and boom. Due to the substantial volume of results generated, they are available upon request.

A.1 The Bayesian Model
The models in (8) and (9) are also known as the Spatial Autoregressive Model (SAR) in the spatial literature (see LeSage & Pace, 2010). We first express (8) and (9) in the compact matrix form such that
where Y is the n × 1 vector of D.MLevi or D.Mat23i, W is the n × n network matrix such that the (i, j)th element is zero if firms i and j are not socially connected and equals to the centrality of j otherwise, X is the n × 4 matrix of regressors specified in (8) and (9), Ds is the dummy matrix for sector effects, \(U = \left( {u_{1} , \ldots u_{n} } \right)\)’ and ui ∼ N (0,\({\sigma }_{u}^{2}\)). Define S(α1) = In − α1W where In is the identity matrix of size n, and let θ = (α0, β’, η’)’. The likelihood function of Y, conditional upon W, X, α1, θ, is given as,
We specify the priors p(α1) = Uniform[− 1, 1] and p(θ) be conventional non-informative normal prior. The posterior of α1 and θ is thus,
The posterior draws from (14) are obtained from the following MCMC iterations.
-
1.
Sample α1 from \(p\left({\alpha }_{1}|\theta ,Y,W,X\right)\)
-
2.
Sample θ from \(p\left(\theta |{\alpha }_{1},Y,W,X\right)\)
The MCMC sampling iterates through the above two steps until convergence. For each step, the draw is conditioned on the rest of parameters with the most updated values at the current iteration.
