This paper seeks to analyse from a comparative point of view the efficiency of the use of manual labour as well as the mechanized works in the cultivation of oil plants in order to obtain profit and the profitability of this activity from the point of view of conventional and ecological crops....

This paper provides new indices of global macroeconomic uncertainty and investigates the cross-country transmission of uncertainty using a global vector autoregressive (GVAR) model. The indices measure the dispersion of forecasts that results from parameter uncertainty in the GVAR. Relying on...

We propose an approach for jointly measuring global macroeconomic uncertainty and bilateral spillovers of uncertainty between countries using a global vector autoregressive (GVAR) model. Over the period 2000Q1-2020Q4, our global index is able to summarize a variety of uncertainty measures, such...

In this paper we perform a meta-analysis on empirical estimates of the impact between investment and uncertainty. Since the outcomes of primary studies are largely incomparable with respect to the magnitude of the effect, our analysis focuses on the direction and statistical significance of the...

We find that shocks to aggregate geopolitical uncertainty are associated with an average decline in firm-level capital investment. The decline in investments increases in the degree of external financial constraints faced by firms, with the effect being stronger for more irreversible...
