Critical import supply elasticities and the ‘imports-as-market-discipline’ hypothesis

Elasticities of supply for the US natural gas market

In this paper we investigate natural gas producer’s reactions to changes in market prices. We estimate price elasticities of aggregated supply in the most competitive market for natural gas: the United States. Using monthly time series data form 1987 to 2012 our analysis is based on an Autoregressive Distributed Lag (ARDL) Bound Cointegration approach to obtain short and long-run elasticities o...

the differential effects of debate and media analysis as relate to enhancing efl learners critical thinking ability and writing performances

critical thinking ability has an important role in education. accordingly, scholars around the world are searching for new ways for teaching and improving students critical thinking ability. in line with the studies in efl contexts supporting the positive relationship between critical thinking and writing performances, this study investigated the differential effects of halverson’s critical thi...

Import Price - Elasticities : Reconsidering the Evidence

Recent economic geography and trade empirical studies based on monopolistic competition [Hanson, 1998; Head and Ries, 1999; Hummels, 1999], suggest high levels of trade price elasticities (between 3 and 11). However, direct estimations of price-elasticities in trade equations, using price indexes at aggregate or industry levels, usually lead to much lower values (around unity). In this paper, w...

Alternative Techniques of Estimating Import Demand Elasticities

T H E desirability as wel l as the difficulty o f obtaining reliable estimates o f import demand elasticities is clearly demonstrated by the extensive literature on the subject during the last few decades. Interest i n price elasticities o f import demand originated in Marshall's [14] discussion o f the possibility o f a devaluation causing a deterioration rather than an improvement in the bala...
