5.2. Endogeneity test and robustness tests 5.2.1. Endogeneity test We first employ the instrumental variable method. To ensure that the instrumental variable is correlated with the endogenous explanatory variables and independent of the random disturbance term, we reference the method proposed by Sun ...
To address potential endogeneity and self-selection bias, we employ double-robust inverse probability weighting (IPW) estimators.Footnote 5 IPW uses the propensity score to compute weights based on the inverse probability of treatment. The procedure assigns high weights to observations in the control ...
More and more companies are turning to emerging markets as sources of global innovation to help transform business and society. However, building innovation capabilities in emerging markets is still elusive for most companies. To understand how some companies are successfully building these capabilities, ...
This study investigates the effect of selectivity bias by comparing the sequential approach—with and without explicitly controlling for endogeneity bias—to the unifying utility function approach. Based on household panel data from three categories, we illustrate the extent to which managerial implications...
Search engine marketing has several circularity issues. Lewis et al. [86] argue that there is an identification problem here due to the endogeneity of advertising. “First, many models assume that if you do not click on the ad, then the ad has no effect on your behavior…Online ads can ...
Consequently, the DM has to internalize the consequences of both actions and motivations. A DM with imperfect reflection will not anticipate that her conformist motivation might play a role, whereas a perfectly reflective DM will know how to handle the endogeneity. Hence, given the objections to ...
There are still some potential endogeneity issues remaining in this regression model. First, the public income may have positive effects on public service investment. Second, it is difficult to control the impact of some potential missing variables except the existing control variables. Therefore, we...
In addition, we also tested covariate continuity to ensure that the assumption of covariates being continuous was accurate, thereby avoiding endogeneity, which could affect our estimation. 4.2.1. Multinomial Kernel Test Triangular kernel test A default triangle-kernel test was used to judge the ...
