Using panel data on IT investment choices and outcomes, we perform the first empirical test of the existence of peer effects and social learning in Jordanian banks’ IT investment decisions. We fit a linear in means model of social interaction and find evidence of peer effects in banks’ choice of IT investment, consistent with the presence of contextual or endogenous effects. Further, a bank’s IT investment increases significantly with other banks’ lagged IT investments, consistent with the presence of social learning. However, a bank’s IT investment does not respond to other banks’ lagged profitability, consistent with the presence of the IT productivity paradox.

我们使用有关IT投资选择和结果的面板数据，对约旦银行IT投资决策中同伴效应和社会学习的存在进行了首次实证检验。我们拟合了一种线性的社会互动均值模型，并发现了银行在选择IT投资方面的同伴效应的证据，与环境或内在效应的存在相一致。此外，与社会学习的存在相一致，银行的IT投资与其他银行的滞后IT投资相比也显着增加。但是，与IT生产率悖论的存在相一致，一家银行的IT投资不能对其他银行的落后盈利能力做出反应。
