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....

The paper explores the fit properties of a class of multivariate Lévy processes, which are characterized as time-changed correlated Brownian motions. The time-change has a common and an idiosyncratic component, to re ect the properties of trade, which it represents. The resulting process may...

This paper constructs a class of multivariate Gaussian marked Poisson processes to model asset returns. The model proposed accommodates the cross section properties of trades, allows for returns to be correlated conditional on trading activity, and preserves the economic intuition of normality...

The traditional multivariate Lévy process constructed by subordinating a Brownian motion through a univariate subordinator presents a number of drawbacks, including the lack of independence and a limited range of dependence. In order to face these, we investigate multivariate subordination,...

Time-changed Brownian motions are extensively applied as mathematical models for asset returns in Finance. Time change is interpreted as a switch to trade-related business time, different from calendar time. Time-changed Brownian motions can be generated by infinite divisible normal mixtures....
