In the absense of frictionless trade, domestic productivity will be a major determinant of prices. Using repeated cross-sections of absolute prices of individual goods across European countries, I find that products of an industry tend to be cheaper in countries with higher productivity in that industry. Similarly, countries with higher productivity in manufacturing have lower prices for produc...

Environmental policies in the United States and abroad are reducing timber harvests while wood demand is mounting. Reduced harvesting on public lands means that privately owned lands will be managed with greater intensity in the United States and that wood will be imported from other nations lacking strong environmental safeguards. It is imperative, therefore, that both public and private fores...

Based on the panel data of 282 Chinese cities from 2014 to 2022, this paper conducts an empirical analysis impact green finance development urban carbon productivity by constructing a difference-in-differences model. It is found that implementation policy promotes improvement productivity; Green has positive effect promoting technology innovation, improving energy structure and environmental pr...

It is indeed a pleasure to be at this World Food Prize celebration here in Des Moines to participate in honoring this year’s co-laureates, Dr. Monty Jones and Prof. Yuan Longping, two giants in rice research. How appropriate it is that we honor them this year—2004, the International Year of Rice. In Africa and Asia, respectively, they have both made remarkable contributions toward the eradicati...

The stay-green mutation of the nuclear gene sid results in inhibition of chlorophyll degradation during leaf senescence in grasses, reducing N remobilization from senescing leaves. Effects on growth of Lolium perenne L. were investigated during N starvation (over 18 d) and after severe defoliation, when leaf growth depends on the remobilization of internal N. Rates of dry mater production, part...

BACKGROUND The indoor built environment plays a critical role in our overall well-being because of both the amount of time we spend indoors (~90%) and the ability of buildings to positively or negatively influence our health. The advent of sustainable design or green building strategies reinvigorated questions regarding the specific factors in buildings that lead to optimized conditions for hea...

Green cyanobacteria differ from the blue-green cyanobacteria by the possession of a chlorophyll-containing light-harvesting antenna. Three genera of the green cyanobacteria namely Acaryochloris, Prochlorococcus, and Prochloron are unicellular and inhabit marine environments. Prochlorococcus marinus attracts most attention due to its prominent role in marine primary productivity. The fourth genu...
