This paper investigates the performance of the IMF WEO growth forecast revisions across different horizons and country groups. We find that: (i) growth revisions in horizons closer to the actual are generally larger, more volatile, and more negative; (ii) on average, growth revisions are in the right direction, becoming progressively more responsive to the forecast error gap as horizons get closer to the actual year; (iii) growth revisions in systemic economies are relevant for growth revisions in all country groups; (iv) WEO and Consensus Forecast growth revisions are highly correlated; (v) fall-to-spring WEO revisions are more correlated with Consensus Forecasts revisions compared to spring-to-fall revisions; and (vi) across vintages, revisions for a given time horizon are not autocorrelated; within vintages, revisions tend to be positively correlated, suggesting perception of persistent short-term shocks.

Do governments in Latin America tend to be optimistic when preparing budgetary projections? We address this question by constructing a novel dataset of the authorities’ fiscal forecasts in six Latin American economies using data from annual budget documents over the period 2000-2018. In turn, we compare such forecasts with the outturns reported in the corresponding budget documents of the following years to understand the evolution of fiscal forecast errors. Our findings suggest that: (i) for most countries, there is no general optimistic bias in the forecasts for the fiscal balance-to-GDP ratio (though there may be for the components); (ii) fiscal forecasts have improved for some countries over time, albeit they have worsened for others; (iii) in terms of drivers, we show that forecast errors for the fiscal balance-to-GDP ratio are positively correlated with GDP growth and terms of trade changes and negatively with GDP deflator surprises; (iv) forecast errors for public debt-to-GDP ratios are negatively associated with surprises to GDP growth; (v) lastly, budget balance rules seem to help contain the size of the fiscal forecast errors.
