FED CATTLE PRICE DISCOVERY: DIRECTED ACYCLIC GRAPH AND TIME SERIES MODELING AgEcon
Lee, Andrew C.; Kim, Man-Keun.
Locating fed cattle price discovery center is revisited using the framework that combines recent progress in causal research with time series analysis. The Bernanke factorization in innovation accounting is obtained by a graphical method called directed acyclic graph which uses data to identify the contemporaneous causal structure among the innovations. This may represent an improvement over the conventional methods which use human judgment and/or theory to supply such information. Results indicate that Kansas market is a dominant price leader where new information is discovered. Contrary to the previous studies, Nebraska market does not appear to be a price discovery location.

MEASURING TECHNICAL EFFICIENCY IN A SMALL-SCALE FISHERY: A causality analysis AgEcon
Sergio, Colin-Castillo.
The analysis of technical efficiency (TE) on the small-scale fishery is relevant for several reasons. While this type of fishery is highly common in developing countries like Mexico, there are a very limited number of analyses assessing their efficiency. Indeed, there is no precise information on the contribution of the small-scale fisheries to livelihoods and economies in developing nations. Exploring this gap in the research would be relevant for the decision making policy. On the one hand, small-scale fisheries can generate significant profits and be more resilient to shocks and crises; two important elements to poverty alleviation and food security. But on the other hand, small-scale fisheries may overexploit stocks, harming the environment and...
