The literature on foreign direct investment (FDI) has analysed the entry mode choice by multinational enterprises (MNEs) from several theoretical viewpoints. Nevertheless, previous studies have mainly focused on the behaviour of large and established MNEs while little attention has been given to small- and medium-sized firms. The paper aims at providing further empirical evidence on the role of firm size and international experience in influencing the ownership structure of FDI. The main hypothesis is that smaller firms, characterised by financial and managerial constraints, as well as firms lacking experience in managing foreign operations, suffer from a condition of adverse asymmetry in information costs, compared to their competitors. Therefore, they are forced to act prudently, minimising risk and thus preferring a less control arrangement of foreign subsidiaries. A binomial logistic model is developed with reference to manufacturing foreign direct investments undertaken by Italian firms in the period 1986-1993.
