This paper applies the mean-variance portfolio optimization (PO) approach and the stochastic dominance (SD) test to examine preferences for international diversification versus domestic diversification from American investors’ viewpoints. Our PO results imply that the domestic diversification strategy dominates the international diversification strategy at a lower risk level and the reverse is ...

We provide an analysis of frontier market equities with respect to world market integration and diversification. Principal component results reveal that frontier markets exhibit low levels of integration. In contrast with developed and emerging markets, frontier markets offer no indication of increasing integration through time. Furthermore, individual frontier market countries do not exhibit c...

In order to prioritise interventions for micronutrient deficiencies in China, the populations affected by iron and zinc deficiencies were assessed based on data from the 2002 China National Nutrition and Health Survey. The costs and cost-effectiveness of supplementation, food diversification and food fortification were estimated using the standard World Health Organization ingredients approach....

This study aimed at examining the merit of crop diversification as a strategy for agricultural growth in Bangladesh. Specifically, the existence of economies of diversification, scale economies and diversification efficiencies at the farm level were examined using a stochastic input-distance function approach. Results reveal strong evidence of diversification economies amongst most crop enterpr...

This paper investigates the impact of constraints of short-sale and over-weight to international diversification benefits. We find that the short-sale restriction alone does not influence the diversifying benefit while the addition of over-weighting constraint significantly worsens mean-variance of optimal portfolio. This finding holds for the analyses of regional and cross-regional portfolios....

During the last decades, the financial markets volatility concept attracted the attention of the theorists and the experts in the field of finance, especially for the internationally diversified wallets. In this article, we used an asymmetric dynamic conditional correlation (DCC-GARCH (1.1)) model following the approach of Engle (2002), to test if the volatility of individual market or their re...

This paper investigates the valuation effects of corporate international diversification by examining cross-border mergers and acquisitions of U.S. acquirers over the period 1990-1999. We find that, on average, acquisitions of “fairly valued” foreign business units do not lead to value discounts. Consistent with the industrial diversification discount literature, unrelated cross-border acquisit...
