Multicollinearity is a serious problem in applied regression analysis. Q. Paris (2001) introduced the MEL estimator to resolve the multicollinearity problem. This paper improves the MEL estimator to the Modular MEL (MMEL) estimator and shows by Monte Carlo experiments that MMEL estimator...

We study the nature of market competition in relation to stability of collusion in the infinitely repeated play of a two-stage game of product innovation and market competition, and show that cooperation in giving R&D efforts is more easily sustained when firms compete in quantity than in price.

The spatial voting approach is extended to account for the existence of a loyalty effect driving the choice of parties' platforms during elections. There emerges a non-linear relationship between these variable, whereby a party sticking to its historical heritage may lose to a rival more keen to...

I investigate R&D efforts for process innovation in a monopoly with uncertain demand. Two different models are proposed, where either (i) the reservation price is affected by an additive shock and the marginal production cost is increasing, or (ii) a multiplicative shock on the slope of demand...
