Method and device for determining heats of combustion of gaseous hydrocarbons

A method and device is provided for a quick, accurate and on-line determination of heats of combustion of gaseous hydrocarbons. First, the amount of oxygen in the carrier air stream is sensed by an oxygen sensing system. Second, three individual volumetric flow rates of oxygen, carrier stream air, and hydrocrabon test gas are introduced into a burner. The hydrocarbon test gas is fed into the burner at a volumetric flow rate, n, measured by a flowmeter. Third, the amount of oxygen in the resulting combustion products is sensed by an oxygen sensing system. Fourth, the volumetric flow rate of oxygen is adjusted until the amount of oxygen in the combustion product equals the amount of oxygen previously sensed in the carrier air stream. This equalizing volumetric flow rate is m and is measured by a flowmeter. The heat of combustion of the hydrocrabon test gas is then determined from the ratio m/n

Intra-industry trade in Latin America and the Caribbean

An increasingly important component of total world trade is intra-industry trade (IIT). The large volume of literature on IIT is reflective of this importance. However, this extensive literature has focused almost completely on explaining the causes of IIT. This focus has left a puzzling gap in the literature. Specifically, it is almost impossible to determine the level of IIT for a particular country or region. Further, there is almost no information on the level of IIT at the industry level either globally or for a region or country. In this paper we provide estimates of IIT for the world and for the countries of the Western Hemisphere. Further, we provide estimates of IIT for ten different SITC product categories on the same basis. The findings of the paper indicate that in most industries, IIT in Latin America is substantially lower overall than the world average. There are, however, substantial variations observed both by country and by industry. Because the results are the first available for the region as a whole, they should allow researchers to get a better picture of the extent of IIT in Latin America and the Caribbean by country and by industry.Intra-industry trade; Latin America

Functional form for United States-México trade equations

The literature concerning bilateral trade flows between Mexico and the United States is comparatively small. With the growing importance of international commerce between these economies, potential trade flow responses to changes in relative prices and income performance deserves more attention. This paper attempts to partially fill this gap in the literature by estimating bilateral trade flow equations that decompose relative import and relative export prices into foreign prices, domestic prices, and the exchange rate.

The Demand for Imports and Exports in Japan: A Survey

One of the more important issues in applied international economics is the extent to which trade flows adjust to changes in income, relative prices, and exchange rates. In this article, we survey the literature on the empirical estimation of the demand for imports and exports for Japan. More precisely, this article updates earlier surveys by Stern et al. (\u27\u27Price Elasticities in international Trade,\u27\u27 Basingstoke, London, 1976) and Goldstein and Khan (in \u27\u27Handbook of International Economics\u27\u27 (P. B. Kenen and R. W. Jones, Eds.), North Holland, Amsterdam, 1985). J. Japan Int. Econ., June 1997, 11(2), pp. 247-259.

An error correction analysis of U.S.-Mexico trade flows

Estimation of bilateral trade elasticities is less well documented than is the case for aggregate trade flows. This study estimates bilateral trade equations for Mexico and the United States. The empirical analysis is carried out using an error correction approach that allows imports and exports to adjust over time to changes in the independent variables that affect the demand for them. Results obtained indicate that imports and exports between the two neighbors react heterogeneously to variations in domestic prices, foreign prices, and currency values. Lag structures between the two trade equations also differ from each other
