Taxonomic study of Hoplias microlepis (Günther, 1864), a trans-Andean species of trahiras (Ostariophysi: Characiformes: Erythrinidae) Neotropical Ichthyology
Mattox,George M. T.; Bifi,Alessandro G.; Oyakawa,Osvaldo T..
The Hoplias malabaricus species group represents one of the most complexes taxonomical problems in the systematics of Neotropical fishes, including specimens widely distributed in most drainages of South America and part of Central America with great variation or overlap of putative diagnostic characters. The large number of nominal species, many of which without known type material, renders the problem more complicated. Currently, at least three nominal species can be included in the Hopliasmalabaricusspecies group based on the form of the medial margins of dentaries and presence of tooth plates on the tongue: Hoplias malabaricus, H. teres, and H. microlepis, the latter representing the only exclusively trans-Andean known species of the genus. We present...

Technical Efficiency and Adoption of Soil Conservation in El Salvador and Honduras AgEcon
Solis, Daniel; Bravo-Ureta, Boris E.; Quiroga, Ricardo E..
A household-level switching regression model is implemented to examine potential selectivity bias for rural households under high and low levels of investments in soil conservation in El Salvador and Honduras. In the presence of selectivity bias, separate stochastic production frontiers are estimated for low and high adopters. The main results indicate that households with higher levels of investments in soil conservation show higher average TE than those with a lower level of investments. Constrains in the rural land and credit markets are likely explanations for these differences. The results also indicate that for farms with lower levels of investments in soil conservation access to credit is a significant factor explaining the sources of inefficiency....

The Impact of the Central America Free Trade Agreement on the Central American Textile Maquila Industry AgEcon
Jansen, Hans G.P.; Morley, Samuel A.; Kessler, Gloria; Pineiro, Valeria; Sanchez, Marco V.; Torero, Maximo.
While the Central America Free Trade Agreement (CAFTA) remains a hotly debated issue in all five Central American countries that are part of the treaty, most discussions are based on preconceived opinions rather than grounded in research-based results. The point of departure of the paper is that the provisions in the agreement concerning the textile maquila industry are likely to have a significant impact on household welfare, despite the already existing preferential access of textile maquila exports to the U.S. market under the rules of origin set by the Caribbean Basin Initiative (CBI) and the U.S.–Caribbean Basin Trade Partnership Act (CBTPA). What CAFTA does for maquila production in Central America is to make permanent and expand the liberalized...
