Forecasting near-term developments within the labour market – Financial institution Underground

Harvey Daniell and Andre Moreira

The most recent developments within the labour market are sometimes central to financial coverage selections. We define a framework for mapping labour market indicators to near-term employment and pay progress, drawing on established insights from the ‘nowcasting’ literature. The important thing advantages of our strategy are: the power to map a variety of ‘tender’ and ‘laborious’ indicators of various frequencies to quarterly official knowledge; the empirical dedication of how a lot weight to position on every indicator; and the power to shift these weights flexibly as extra knowledge change into obtainable. This framework beats easy benchmark fashions in our labour market utility.

Understanding the newest developments within the labour market is commonly key for financial coverage selections. In Might, for instance, the Financial Coverage Committee linked additional tightening in financial coverage to, amongst different issues, the tightness of labour market situations and the behaviour of wage progress.

Nonetheless, official knowledge on the labour market are printed with a lag. To enhance understanding of present situations when setting coverage, it’s essential to extract the sign from extra contemporaneous indicators to ‘nowcast’ – ie to foretell present and near-term developments in – the labour market.  

What are the important thing insights of our strategy?

1: Arduous and tender indicators, of various frequencies, could be mapped individually and on to the goal labour market variable.

The expansion of high-frequency knowledge over the previous decade or so means now we have indicators of the labour market at quarterly, month-to-month, and even weekly frequency. These indicators could be mapped individually to a goal variable, resembling quarterly employment progress, utilizing ‘mixed-data sampling’ (or ‘MIDAS’) strategies. MIDAS strategies are ‘primarily tightly parameterised, diminished type regressions that contain processes sampled at completely different frequencies‘.

These strategies have the benefit of having the ability to deal with knowledge of various frequency, avoiding the necessity to convert variables to the identical frequency, resembling lowering weekly knowledge to quarterly. This implies we keep away from any lack of data (or use of further assumptions) that reworking variables to the identical frequency entails.

An additional good thing about our explicit strategy is the power to map every indicator individually to the variable of curiosity, earlier than combining these into an total mannequin nowcast. In different phrases, we begin by acquiring a unique nowcast from every indicator, which is commonly of curiosity to policymakers, because it permits us to debate options such because the dispersion throughout particular person indicators.

For instance, Chart 1 illustrates the nowcasts for quarterly employment progress from MIDAS regressions utilizing a variety of labour market indicators. The gray traces illustrate the person nowcasts, which observe the goal variable, within the blue line, pretty nicely, regardless of the volatility within the latter.

Chart 1: Indicator-based nowcasts for quarter on quarter employment progress (per cent) (a)

(a) Indicator-based nowcasts are based mostly on Financial institution of England Brokers’ scores, the Lloyds Enterprise Barometer, ONS/HMRC PAYE payrolls progress, S&P International/CIPS Buying Managers Index and KPMG/REC Report on Jobs.

2: The steer from completely different indicators could be mixed into one total view, the place the weights are knowledgeable by the data content material of the related indicator.

Totally different indicators usually level to completely different nowcasts for a similar variable, so it’s important to know the way a lot weight to position on every indicator. In our strategy, we weight the steer from every indicator based on its relative forecast efficiency within the latest previous – a standard strategy within the forecasting literature, which we discover additionally works nicely on this utility to the UK labour market. In different phrases, extra correct indicators obtain the next weight.

Chart 2 and Chart 3 plot a measure of forecast efficiency for a variety of indicators of quarter-ahead employment and pay progress. They present that ‘tender’ indicators just like the month-to-month employment steadiness of the S&P International/CIPS Buying Managers Index and the month-to-month KPMG/REC Report on Jobs carry out the most effective at predicting quarterly employment and pay progress, two quarters forward. Crucially, although, the mixed steer from all indicators outperforms counting on any particular person indicator alone.

Chart 2: Forecast efficiency of indicators of employment progress, two-quarters forward (a)

Chart 3: Forecast efficiency of indicators of pay progress, two-quarters forward (a)

(a) ‘RMSE’ is root imply squared error, a regular measure of historic forecast efficiency. ‘BCC’ is British Chambers of Commerce quarterly financial survey. ‘Vacancies’ are ONS three-month vacancies progress. ‘Lloyds’ is Lloyds Enterprise Barometer. ‘GDP’ is ONS three-month GDP progress. ‘Payrolls’ are ONS/HMRC PAYE payrolls and median pay progress. ‘REC’ is KPMG/REC Report on Jobs. ‘PMI’ is S&P International/CIPS Buying Managers Index. ‘Brokers’ are Financial institution of England Brokers’ scores for employment and pay progress. ‘Job-to-job strikes’ are ONS quarterly flows knowledge. ‘Cycle’ indicator is sum of CPI inflation and the (inverse) unemployment hole from Financial institution of England Financial Coverage Studies.

It’s attention-grabbing to notice that, inside the vary of particular person nowcasts, tender indicators are likely to carry out significantly better than previous observations of the ‘laborious’ knowledge – ie obtainable month-to-month observations of the goal ONS variable. Basically, it’s because the laborious knowledge are risky, and are subsequently not essentially very informative even about their very own trajectory. 

3: The weights positioned on every indicator change over the info cycle, which is especially essential for the relative weights positioned on ‘laborious’ versus ‘tender’ indicators of the labour market.

When new knowledge change into obtainable, the mapping between a given indicator and the goal variable can even change, generally in fairly an essential method. So it’s essential to re-specify and re-estimate the underlying relationships every time the data set modifications. Acknowledging this, the mannequin can also be arrange in a method that permits it to optimally shift the burden placed on ‘laborious’ data (resembling ONS knowledge) versus ‘tender’ data (resembling enterprise surveys) over the info cycle. This optimum weighing takes place in a easy second-stage OLS regression.

Taking a step again, updating the near-term outlook for an increasing data set is a crucial supply of lowering forecast error, not least as a result of month-to-month observations of the laborious knowledge, which the ONS additionally publishes, are a direct enter to the calculation of the quarterly outturn.

Early within the knowledge cycle, when no intra-quarter official knowledge can be found, the mannequin tells us to position extra weight on the timelier tender indicators such because the month-to-month enterprise surveys. As soon as intra-quarter month-to-month laborious knowledge change into obtainable, nonetheless, these start to obtain a a lot increased weight.

Beneath this strategy, the total mannequin’s common forecast error progressively declines every time new knowledge change into obtainable however, unsurprisingly, the development is especially putting on the juncture the place the laborious indicators are available to complement the steer from tender indicators. Chart 4 illustrates this level for a nowcast of employment progress.

Chart 4: Common forecast error for quarterly employment progress declines as extra knowledge change into obtainable

Seen on this method, the framework can inform us each the marginal impression of recent knowledge on some extent estimate of the nowcast, in addition to the extent to which the brand new knowledge additionally cut back uncertainty round that nowcast.

4: The strategy considerably outperforms easy benchmark fashions for forecasting the labour market.

The important thing insights outlined above are essential sources of lowering forecast error. For instance, in a forecast for employment and pay progress two quarters forward, the mixed forecast wherein a collective steer is taken from a variety of indicators typically outperforms counting on any single indicator alone.

Furthermore, the mixed nowcast from the total mannequin outperforms a easy autoregressive benchmark mannequin – ie a easy mannequin of quarterly employment/pay progress based mostly on lagged employment/pay progress. That is typically true in any respect states of the info cycle, with the discount in root-mean-squared errors rising to round 65% previous to the discharge of the outturn.

Certainly, the mannequin’s forecast efficiency on the quarter-ahead horizon is much like the one-quarter forward forecasts from successive Financial Coverage Studies. This displays the truth that the strategy outlined right here formalises most of the present heuristics that forecasters on the Financial institution make use of, resembling putting extra weight on softer indicators early within the knowledge cycle, and counting on a variety of information.

Curiously, efficiency on the one-year-ahead horizon of the mixed mannequin truly barely outperforms successive Financial Coverage Studies. That is prone to replicate two components: data-driven approaches to forecasting could outperform extra structural fashions like these supporting the Financial Coverage Report on the one-year horizon; and Financial Coverage Report forecasts are conditional forecasts, whose forecast accuracy is just one requirement of the mannequin amongst many different necessities.
