Trade Costs, 1870–2000 [PDF]

open access: yesAmerican Economic Review, 2008
What has driven trade booms and trade busts in the past century and a half? Was it changes in global output or in the costs of international trade? To address this question, we derive a micro-founded measure of aggregate bilateral\ud trade costs based on a standard model of trade in differentiated goods.

Over one‐third of cancer cases and two‐fifths of cancer deaths in southern China are preventable: Insights from the latest representative population‐based cancer registry data and risk factor survey

open access: yesInternational Journal of Cancer, EarlyView.
What's New? This study quantified the cancer burden attributable to modifiable risk factors in Guangdong, the most populous and economically advanced province in southern China. By evaluating 15 modifiable risk factors, the study reveals that over one‐third of cancer cases and two‐fifths of cancer deaths in the region could potentially be prevented ...

Noncausal AR‐ARCH Model and Its Applications to Financial Time Series

open access: yesInternational Journal of Finance &Economics, EarlyView.
ABSTRACT We extend the noncausal autoregressive models by introducing noncausality into the variance component, allowing the volatility to depend on future prices as well. We refer to this model as the noncausal AR‐ARCH model, and it enables us to account for shocks arising from market agents who possess more information and engage in forward‐looking ...

Fast Mid‐Infrared Spectral Probe Decisions Match H&E Stain Results for Keratinocytic Carcinoma

open access: yesJournal of Biophotonics, EarlyView.
A handheld and fast mid‐infrared fiber‐optic spectral probe is touched to tissue recording a mid‐infrared spectrum that can distinguish keratinocytic cancer from normal skin. ABSTRACT We designed a handheld and fast mid‐infrared fiber‐optic spectral probe using a quantum cascade laser (QCL) and a reduced range of wavelengths, to see if keratinocytic ...

New age‐estimate data and implications for marine isotope stage 7 and 5e sea levels in Fenland, eastern England

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Only one last interglacial relative sea‐level indicator point (SLIP) has been recognised for Fenland, eastern England, and the nearest penultimate interglacial SLIP is located on the north Norfolk coast. Such limited information restricts the regional input to, and hence the relevance of, global reconstructions of late Middle and Late ...

Elevated carbon dioxide can boost freshwater zooplankton abundance, while warming may shift community composition, weakening phytoplankton control

open access: yesLimnology and Oceanography, EarlyView.
Abstract Zooplankton communities in ponds and lakes control phytoplankton growth and serve as a food source for higher trophic levels such as fish. Recent experiments have shown that several freshwater zooplankton species as well as the phytoplankton communities on which they feed can be variably affected by rising temperatures, reduced pH and higher ...
