We illustrate two differential oligopoly games with capital accumulation where, alternatively, the accumulation dynamics of productive capacity is modelled either `a la Solow—Swan or `a la Ramsey. We show that in the first case the open-loop Nash equilibrium is only weakly time consistent,...

We analyze a two-stage game in a vertically differentiated duopoly with two regions which can differ for the willingness to pay of their consumers or for the market size; firms sequentially choose to settle in one region and then simultaneously compete in prices, selling their products both on...

We model the optimal behaviour of a multiproduct monopolist investing both in process and in product innovation in a dynamic setting. Product innovation reduces the degree of substitutability between any two varieties. First, we find that R&D efforts increase in both directions as the number of...

In a closed economy context there is common agreement on price inflation stabilization being one of the objects of monetary policy. Moving to an open economy context gives rise to the coexistence of two measures of inflation: domestic inflation (DI) and consumer price inflation (CPI). Which one...

Traditional tools fail to capture the value of new ventures, such as R&D projects and start-up companies, because of their dependence on future events that are uncertain at the time of the initial decision. In the real options setting the value of these investments is the value of the follow-on...

It is well known that, in a multinomial probit, only the covariance matrix of the location and scale normalized utilities are identified. In this study, we explore the relation between these identifiable parameters and the original elements of the covariance matrix, to find out what can be...

We analyse a model of patient decision-making where anxiety about the future characterizes the patient's utility function. Anxiety corresponds to fear of bad news and results in the patient being averse to information. First, the patient chooses the accuracy of a signal which discloses...

In a two sectors, two regions economy I show that the higher increasing returns to scale of an industry, the easier it will concentrate in response to natural advantage. To this end, one sector is assumed to be perfectly competitive and the other is monopolistically competitive, with a region's...
