A robust game is a distribution-free model to handle ambiguity generated by a bounded set of possible realizations of the values of players' payoff functions. The players are worst-case optimizers and a solution, called robust-optimization equilibrium, is guaranteed by standard regularity conditions. The paper investigates the sensitivity to the level of uncertainty of this equilibrium. Specifically, we prove that it is an epsilon-Nash equilibrium of the nominal counterpart game, where the epsilon-approximation measures the extra profit that a player would obtain by reducing his level of uncertainty. Moreover, given an epsilon-Nash equilibrium of a nominal game, we prove that it is always possible to introduce uncertainty such that the epsilon-Nash equilibrium is a robust-optimization equilibrium. An example shows that a robust Cournot duopoly model can admit multiple and asymmetric robust-optimization equilibria despite only a symmetric Nash equilibrium exists for the nominal counterpart game.
This study surveys theoretical models providing alternative rationales for corporate hedging.
The rise of “born global” companies, i.e. companies that internationalize their activities from inception or shortly thereafter led researchers to explore the various aspects related to early internationalization. Nevertheless, authors argue that further evidence and analysis on these firms is required. Based on a multiple case study research the paper aims at providing further evidence on this phenomenon. An in-depth qualitative analysis has been performed based on eight startups founded by Italian entrepreneurs that showed an early internationalization towards the US and the Silicon Valley in particular. They have been interviewed with the goal of validating the major drivers of internationalization the literature attributes to born global companies. The cross case study analysis carried out highlights that not all the drivers seem to be equally relevant. The major findings of the study are twofold. First, the importance of professional networks built by entrpreneurs before establishing the company. Secondly, how the entrepreneur’s prior experience abroad (either as entrepreneur or as employee or for studying reasons) triggers and orients the internationalization path of a company
The paper shows that cardinal utility entered economic analysis during the Ordinal Revolution initiated by Pareto and not, as many popular histories of utility theory assume, before it. Cardinal utility was the outcome of a discussion begun by Pareto about the capacity of ranking transitions among different combinations of goods. The discussion simmered away during the 1920s and early 1930s, underwent a decisive rise in temperature between 1934 and 1938, and continued with some final sparks until 1944. The paper illustrates the methodological and analytical issues and the measurement-theoretic problems, as well as the personal and institutional aspects that characterized this debate. Many eminent economists of the period contributed to it, with Samuelson in particular playing a pivotal role in defining and popularizing cardinal utility. Based on archival research in Samuelson’s papers at Duke University, the paper also addresses an issue of priority associated with the mathematical characterization of cardinal utility.
This study explores the characteristics of Italian foreign direct investment (FDI) in India and aims at filling the gap identified in the literature by providing a comprehensive empirical analysis on this issue. More specifically, we try to understand the reasons behind internationalization decisions in India, the strategic goals associated with them (i.e. manufacturing vs. commercial), the role played by the Indian subsidiary and its value chain configuration. In order to investigate the research questions, a unique database of Italian firms that invested in India was created. The first empirical confirmation we collected was about the low number of Italian companies with subsidiaries in India. In terms of internationalization goals it emerges clearly from the research that the main target is market seeking. In order to acquire that market share Italian companies have organized their subsidiaries as partially independent companies, adopting a typical “Multidomestic” approach customizing products and services to the local needs and demands.Moreover, the industry fragmentation suggests that so far only the best in each class hav approached India. This is indirectly confirmed by the fact that it is indeed almost impossible to find two Italian competitors present at the same in India.
