This paper provides the first empirical attempt of linking firms' profits and investment in R&D revisiting Knight's (1921) distinction between uncertainty and risk. Along with the risky profit-maximizing scenario, identifying a second, off-setting, unpredictable bias that leads to heterogeneous...

This paper provides the first empirical attempt of linking firms' profits and investment in R&D revisiting Knight's (1921) distinction between uncertainty and risk. Along with the risky profit-maximizing scenario, identifying a second, off-setting, unpredictable bias that leads to heterogeneous...

In this paper we focus on robust linear optimization problems with uncertainty regions defined by ø-divergences (for example, chi-squared, Hellinger, Kullback-Leibler). We show how uncertainty regions based on ø-divergences arise in a natural way as confidence sets if the uncertain parameters...
