The standard way in which disaster damages are measured involves examining separately the number of fatalities, of injuries, of people otherwise affected, and the financial damage that natural disasters cause. Here, we propose a novel way to aggregate measures of disaster impact, which aims to...

Why do people save? A strand of the literature has emphasized the role of ‘precautionary’ motives; i.e., private agents save in order to mitigate unexpected future income shocks. An implication is that in countries faced with more macroeconomic volatility and risk, private saving should be...

We quantify the ‘permanent’ socio-economic impacts of the Great Hanshin-Awaji (Kobe) earthquake in 1995 by employing a large-scale panel data set of 1,719 wards from Japan over three decades. In order to overcome a fundamental difficulty of identifying the counterfactual, i.e., the Kobe...

We tabulate and measure the burden of disasters on the Pacific Island Countries (PICs) by aggregating and comparing the data found in the two global datasets on disaster impacts. We show that the most commonly used dataset greatly underestimates the burden of disasters for the Pacific islands....

The variance of New Zealand's real GDP has declined since the mid-1980s. To investigate why, this paper decomposes the variance of chain-weighted estimates of production-based real GDP growth into sector shares, sector growth rate variances and co-variances. The principal explanation for the...

This paper fits hidden Markov switching models to New Zealand GDP data. A primary objective is to better understand the utility of these methods for modelling growth and volatility regimes present in the New Zealand data and their interaction. Properties of the models are developed together with...
