Why are some households so poorly insured?

Why are some proteins structures so common?

Many biological proteins are observed to fold into one of a limited number of structural motifs. By considering the requirements imposed on proteins by their need to fold rapidly, and the ease with which such requirements can be fulfilled as a function of the native structure, we can explain why certain structures are repeatedly observed among proteins with negligible sequence similarity. This ...

Why is gout so poorly managed?

G out has been recognised since ancient times, and we currently have a deep understanding of its pathophysiology. The disease results from a deposit of monosodium urate (MSU) crystals in joint structures and in other, generally periarticular, sites in the form of tophi. High serum uric acid (SUA) is required for the formation of these crystals. The most characteristic features of gout are acute...

Why Do Chinese Households Save So Much?

Using a dataset that covers 5 decades (1960–2009), we show that the main determinants of China's household savings rate are disposable income (measured by its reciprocal) and the old-age dependency rate. The income growth rate and young age dependency rate have a limited role. Our findings support the Keynesian saving hypothesis instead of Modigliani’s life cycle hypothesis, although precaution...

Investigating determinants of catastrophic health spending among poorly insured elderly households in urban Nigeria

BACKGROUND In the absence of functional social security mechanisms for elderly people in Nigeria, elderly households are solely responsible for geriatric healthcare costs, which can lead to catastrophic health expenditures (CHE) - particularly among the poor. This study investigates the key determinants of CHE among poorly insured elderly households in Nigeria. We also offer some policy options...
