In this paper, we attempt to study quantitatively the effects on macroeconomics due to different shocks. The interactions between different shocks are the major subjects. Furthermore, the dynamics of shocks, i.e, the time evolutions of shocks, and the propagation of shocks are studied in detail...

An impulse response is the dynamic average effect of an intervention across horizons. We use the well-known Kitagawa-Blinder-Oaxaca decomposition to explore a response's heterogeneity over time and over states of the economy. This can be implemented with a simple extension to the usual local...

The question of how climate change affects the economy through temperature fluctuations is high on the economic research agenda, as the identification of exogenous weather shocks is still an open issue. Using daily county-level data since 1970, we construct a series of temperature shocks for the...

We find that deep contractions have highly persistent scarring effects, depressing the level of GDP at least a decade hence. Drawing on a panel of 24 advanced and emerging economies from 1970 to the present, we show that these effects are nonlinear and asymmetric: there is no such persistence...

The question of how climate change and weather fluctuations affect the economy is high on the economic research agenda, but the quantification of the effects of temperatures at infra-annual frequencies still remains an open issue. Using daily county-level data since 1970, I construct quarterly...

I provide evidence that portfolio equity inflows can have expansionary effects on GDP and inflation if not offset by monetary policy. I use a shift-share instrument to estimate equity inflows based on plausibly exogenous timing of inflows into mutual funds with heterogeneous country portfolios....

Firms’ market power, measured by markups, has risen substantially and unequally across sectors. To evaluate the implications of these trends for monetary non-neutrality, we develop a quantitative menu cost model that covers multiple sectors with heterogeneous degrees of market competition. Two...

A Real Business Cycle model of the UK is developed to account for the behaviour of UK nonstationary macro data. The model, when tested by the method of indirect inference, can explain the behaviour of main variables (GDP, real exchange rate, real interest rate). We use it to explain how 'crisis'...
