Última INTERNATIONAL VARIATION IN RETURN ON EQUITY IN THE FOOD AND BEVERAGE INDUSTRIES AgEcon Acheampong, Yvonne J.. The objective is to analyze the effects of country- and firm-specific factors on the return on equity in the beverage and tobacco and food and consumer-products industries for 11industrialized nations. The results indicate that country- and firm-specific factors are important in explaining variation in return on equity within countries but not generally across countries or time.

Ano: 2000 URL: http://purl.umn.edu/15493 Tests for unbalanced error-components models under local misspecification AgEcon Sosa-Escudero, Walter; Bera, Anil K.. This paper derives unbalanced versions of the test statistics for firstorder serial correlation and random individual effects summarized in Sosa-Escudero and Bera (2001, Stata Technical Bulletin Reprints, vol. 10, pp. 307–311), and updates their xttest1 routine. The derived test statistics should be useful for applied researchers faced with the increasing availability of panel information where not every individual or country is observed for the full time span. The test statistics proposed here are based on ordinary least-squares residuals and hence are computationally very simple.

Ano: 2008 URL: http://purl.umn.edu/120929 Effects on milk supply of different systems of livestock feeding AgEcon Casasnovas, Valero L.; Aldanondo, Ana Maria. Determining the competitive position of dairy farms depends on several technological, economic and institutional variables. Among them, are remarkable those related to animal feeding in the current context of high variability on prices. In this context, the aim of this study is to analyze the effects on milk supply and the competitiveness of dairy farms with different models of land intensification, with greater reliance on market purchases or self-production of livestock feed. This study is based on an econometric approach to a variable cost function, in a fixed effects model for unbalanced panel data of specialized dairy farms in Navarre (Spain). From this region, we use 3 geographical areas in relation to the availability of grazing land. It has been...
