| The “Nouveau recueil de planches coloriées” of Temminck & Laugier (1820-1839) contains many descriptions of new birds and is of fundamental importance to the history of ornithology. A new detailed review of the evidence presented by the book itself has brought clarity to the relationships between the plates and the livraisons2 of which they were a part. The opportunity has been taken to provide a fresh list of dates for the livraisons, this contains minor changes to that of Zimmer (1926) and the earlier, more widely known one of Sherborn (1898). After this study reached its conclusions important new information has come to light, which confirms the main findings. The second part of this paper reviews specific cases investigated. These relate to Asian... |

| To quantify price responsiveness and economic substitutability among wheat classes, derived demand functions were specified from a normalized quadratic profit function. Own-price and cross-price elasticities were estimated for hard red winter, hard red spring, soft wheat (combined red and white), and durum wheat. In general, soft wheat varieties were less responsive to their own price than were hard wheat varieties. Cross-price elasticities indicate that hard red winter wheat, hard red spring wheat, and soft wheat varieties are economic substitutes. Cross-price elasticities are different from those previously reported, which can have important policy implications. |

| Interfuel substitutability has been of longstanding interest to energy economists and policy makers. However, there has been no quantitative meta-analysis of this literature. This research report fills this gap by analysing a broad sample of studies of interfuel substitution in the industrial sector, manufacturing industry or sub-industries, and macro-economy of a variety of developed and developing economies. The primary study sample size has been included in the meta-regression to control for publication bias. At the industrial level, results for the shadow elasticities of substitution between coal, oil, gas, and electricity for forty-six primary studies show that, except for gas-electricity and coal-electricity, there are easy substitution... |
