This paper examines if (and how) continuous-time trading renders dynamically-complete a financial market in which the underlying risk process is a Brownian motion and the securities pay dividends that are proportional to geometric Brownian motions. A sufficient condition, that the instantaneous...

In post-Unification Italy the cyclical movements of the economy largely reflected those in the production of durable goods. The engineering industry has been seen as one that transformed metal into machines: its metal consumption suggests that investment in machinery followed the Kuznets-cycle...

In Italy two censuses were taken in 1911: the usual demographic census, that contains labor-force data, and the first industrial census, that contains employment data. The two yield aggregate figures that are very far apart. The literature directly concerned with estimating industrial employment...

This paper presents the second-generation estimates for the Italian engineering industry in 1911, a year documented both by the customary demographic census, and the first industrial census. The first part of this paper uses the census data to estimate the industry’s value added, sector...

In the literature the (Italian) engineering industry is seen as one that transformed metal into machines; its time path is inferred from that of its consumption of metal. Newly recovered evidence indicates that far more metal was turned into (traditional) hardware than into (modern) machines....

This paper studies the pricing implications of the sole ambiguity aversion, in a Lucas’ tree economy where asset returns are ambiguous. Abstracting from a specific functional form, we disentangle the model-specific effect from the effect of ambiguity aversion. In addition, we allow the...

We show that the introduction in a power utility function of a confidence index to sig- nal the state of the world allows for an otherwise standard asset pricing model to match the observed consumption growth volatility and excess returns with a reasonable level of relative risk aversion. Our...
