An integrated monetary growth model of Keynes–Metzler–Goodwin type with a portfolio approach to its three asset markets (money, bonds, equities) is introduced to study the interaction between the real and the financial part of market economies. Beneath expectations and governmental behavior, profits and their implied dividend payments influence the behavior of asset markets, which determine int...

It is well known that increasing returns to scale and firms’ market power are two potential sources of sunspot expectations in Neoclassical models. In this paper we show that both the degree of returns to scale and market power can have fundamentally different implications for self-fulfilling expectations in New Keynesian models depending on the nature of price rigidity. As a result, the design...

In this paper we study the existence of bubbles for pricing equilibria in a pure exchange economy à la Lucas, with infinitely lived homogeneous agents. The model is analyzed under fairly general assumptions: no restrictions either on the stochastic process governing dividends’distribution or on the utilities (possibly unbounded) are required. We prove that the pricing equilibrium is unique as l...

The paper examines the economic role of modelling information on the decision problem of an exporting firm under exchange rate risk and hedging. Information is described in terms of market transparency, i.e., a publicly observable signal conveys more information about the random foreign exchange rate. We analyze the interaction between market transparency and the ex ante expected utility of the...

We show that high R&D input share must be reflected by high market share, and R&D investment increases with the success probability. Not consistently with the prevailing viewpoint, we also find firms’ R&...
