Purpose– Thepurposeof this paper is to empirically investigate the impact of corruption on foreign direct investment (FDI) and its two major modes of entry: greenfield investment (greenfield) and cross-border mergers andacquisitions (M&As). Design/methodology/approach– Data are collected from 131 countries. Modern econometric techniques, including the generalized method of moments (GMM) estimator, two-stage least square estimator andtwo-step system GMMestimator,areusedtoevaluatetheimpact ofcorruptionon FDI activities. Findings– Theempiricalresults illustrate that corruption is a deterioration factor that significantly hinders FDI inflows. However, this finding turns out to be contradictory when the two major components of FDIgreenfield investment and cross-border M&As– are separately examined. Specifically, while corruption consistently discourages cross-border M&As over time, it appears to exert positive effect on greenfield investments. Originality/value– Thisisamongthefirsttoempirically examine the impact of corruption on FDI andits modes of entry in a number of countries spanning different time windows. In this sense, this paper also captures the changing nature of societies and economic conditions overtime and, therefore, enable academic researchers, policy-makers and business practitioners to draw broad inferences from the empirical results.<p></p>
