Rat foetuses from intra-uterine days E14 through E22 (day before parturition) and adults were used for a quantitative scanning electron-microscopic examination of ciliogenesis in olfactory receptor cells and microvillogenesis in olfactory supporting cells. Four developmental stages in olfactory ciliogenesis can be discerned. Two of these are characterized by the presence of primary cilia only, ...

In this paper, employing VAR and factor analytic models with quarterly U.K. sectoral business investment data, we show that both common and sector–specific shocks play important roles in explaining business investment fluctuations. JEL: C32, E22, E32.

We study how total factor productivity (TFP), energy prices, and the Great Moderation are linked. First we estimate a joint stochastic process for the energy price and TFP and establish that until the second quarter of 1982, energy prices negatively affected productivity. This spillover has since disappeared. Second, we show that within the framework of a dynamic stochastic general equilibrium ...

This paper estimates the effects of exogenous changes in income and consumption taxes. The tax shocks are proxied with a narrative account liability United Kingdom. Income cuts have large on GDP, private consumption, investment. modest not statistically significant GDP its components. Shifting burden taxation from to is expansionary. Consistent conventional public finance theories, these result...

The measured optical transition energies Eii of single-wall carbon nanotubes are compared with bright exciton energy calculations. The Eii differences between experiment and theory are minimized by considering a diameter-dependent dielectric constant kappa, which comprises the screening from the tube and from the environment. Different kappa dependencies are obtained for (E11(S), E22(S), E11(M)...

We estimate the development effects of electrification across Brazil over the period 1960–2000. We simulate a time series of hypothetical electricity grids for Brazil for the period 1960–2000 that show how the grid would have evolved had infrastructure investments been made based solely on geography-based cost considerations. Using the model as an instrument, we document large positive effects ...

This paper provides a simple dynamic optimization model of durable goods inventories. Closed-form solutions are derived in a general equilibrium environment with imperfect information and serially correlated shocks. The model is then applied to scrutinize some popular conjectures regarding the causes of the volatility reduction of GDP since 1984. JEL Classification: E22, E23, E32.

We construct a time-series model of investment in Israel that incorporates both traditional economic factors derived from a theoretical model of a profit-maximising representative firm and indicators of political instability and unrest. This is used to estimate the extent to which the Intifada has depressed Israeli investment and the size of the corresponding "peace dividend". JEL Classificatio...

In this paper we use the frequency domain Granger causality test of Breitung/Candelon (2006) to analyse short and long-run causality between energy prices and prices of food commodities. We find that the oil price Granger causes all the considered food prices. However, when controlling for business cycle fluctuations this link exists especially at low frequencies. Thus, short-run phenomena like...

We conduct a benefit-cost analysis of a relicensing agreement for two hydroelectric dams in Michigan. The agreement changed daily conditions from peaking to run-of-river flows. We consider three categories of costs and benefits: producer costs of adapting electricity production to the new time profile of hydroelectric output; benefits of reductions in air pollution and greenhouse gas emissions;...
