Electoral Cycles in Macroeconomic Forecasts

This paper investigates whether governments release over-optimistic forecasts for GDP growth approaching elections. High-frequency data at the forecaster level from the United States, Sweden, and the United Kingdom document that governments overestimate short-term GDP growth by 0.160.31 percentage points in the months approaching a vote. Consistent with a model of political selection, in which the incumbent government releases optimistic forecasts to signal high ability in order to increase re-election probability, we find that the bias is larger when the incumbent government is not term-limited or constrained by a parliament led by the opposition. Moreover, the bias is allocated across different forecast horizons based on election seasonality. We also show that a reform that outsourced the main forecasting function from the HM Treasury in the United Kingdom to a newly formed government agency reduced the overall bias of forecasts, but not the electoral cyclicality.

Biased Forecasts to Affect Voting Decisions? The Brexit Case

This paper introduces macroeconomic forecasters as political agents and suggests that they use their forecasts to influence voting outcomes. We develop a probabilistic voting model in which voters do not have complete information about the future states of the economy and have to rely on macroeconomic forecasters. The model predicts that it is optimal for forecasters with economic interest (stakes) and influence to publish biased forecasts prior to a referendum. We test our theory using high-frequency data at the forecaster level surrounding the Brexit referendum. The results show that forecasters with stakes and influence released much more pessimistic and incorrect estimates for GDP growth subject to the leave outcome than other forecasters.

Inefficient Use of Competitors’ Forecasts?

This paper assesses to what extent forecasters make efficient use of competitors’ forecasts. Using a panel of forecasters, I find that forecasters underuse information from their competitors in their forecasts for current and next year’s annual GDP growth and inflation. The results also show that forecasters increase the attention to their competitors as the forecast horizon decreases. In a model of noisy information with fixed target forecasts, I confirm the empirical results of underuse of competitors’ information. I also extend the model to include a revision cost and show how this can explain the observed inefficiency and observed horizon dynamics. Using the same model framework, I also rule out overconfidence as the main explanation of the observed behavior.

Withering Cash: Is Sweden ahead of the curve or just special?

There is much in our increasingly digitized economies to suggest that the use of cash should fall. However, in almost all countries, it is constant or rising with a few notable exceptions. Sweden, in particular, displays a divergent development. In this paper, we explore the drivers behind this development. We use a data set consisting of 129 developed and developing countries and an extensive set of possible explanatory variables to estimate panel regressions for cash demand. In line with earlier studies, we find that economic development, demography, and the interest rate are important factors. A new finding is that our estimations point to a negative relationship between cash and corruption, and between cash and trust in government and financial institutions. However, this is not enough to fully explain the divergent development in Sweden. We therefore also discuss some recent events and policy measures in Sweden that seem to have accelerated the decline in cash during the last decade.

Adjusting for Information Content when Comparing Forecast Performance, Journal of Forecasting, 36, 784–794, 2017

Cross‐institutional forecast evaluations may be severely distorted by the fact that forecasts are made at different points in time and therefore with different amounts of information. This paper proposes a method to account for these differences when analyzing an unbalanced panel of forecasts. The method computes the timing effect and the forecaster's ability simultaneously. Monte Carlo simulation demonstrates that evaluations that do not adjust for the differences in information content may be misleading. In addition, the method is applied to a real‐world dataset of 10 Swedish forecasters for the period 1999–2015. The results show that the ranking of the forecasters is affected by the proposed adjustment.
