This paper uses a "trendy" approach to understand UK inflation dynamics. It focuses on the time series to isolate a low-frequency and slow-moving component of inflation (the trend) from deviations around this trend. We find that this slow-moving trend explains a substantial share of UK inflation...

We show that exchange rate pass-through to consumer prices varies not only across countries, but also over time. Previous literature has highlighted the role of an economy's "structure" - such as its inflation volatility, inflation rate, use of foreign currency invoicing, and openness - in...

We present a sticky-price model incorporating heterogeneous firms and systematic firm-level productivity trends. Aggregating the model in closed form, we show that it delivers radically different predictions for the optimal inflation rate than canonical sticky price models featuring homogenous...
