Globally, food systems have become heavily industrialized and are currently threatening both environmental sustainability and human health. Feeding a growing world while remaining within safe social-ecological planetary boundaries, as dictated by the UN Social Development Goals and the Paris...

Recently, there has been considerable work on stochastic time-varying coefficient models as vehicles for modelling structural change in the macroeconomy with a focus on the estimation of the unobserved paths of random coefficient processes. The dominant estimation methods, in this context, are...

Over time, economic statistics are refined. This means that newer data is typically less well measured than old data. Time variation in measurement error like this influences how forecasts should be made. We show how modelling the behaviour of the statistics agency generates both an estimate of...

This paper reports results from a survey by the Bank of England in 1995 to assess the extent of price-stickiness in 654 UK companies. In the year before the survey, firms on average reviewed prices monthly but changed them only twice. Time-dependent pricing was far more prevalent than...

This paper looks at disaggregated price data in the UK to see if there is evidence of downward nominal rigidity: are prices less likely to fall after a downward shock than they are to rise after an upward shock? The test is to see if, as the mean inflation rate falls, the skewness, or the...
