Abstract This paper presents a model where misallocation in the agricultural factors of production is caused by transportation costs to and from local markets, which result an inefficiently large share inputs operated less productive subsistence farmers.

This paper documents that a significant portion of trade for Taiwan and Korea follows the trend of world trade in moving toward a pattern of vertical specialization (VS). Noteworthy is the manufacturing sector, whose VS shares of exports has been steadily increasing and has accounted for more than 90% of the total VS shares of manufactured exports. For Taiwan, nearly 57% of the growth in export...

In this paper, we consider both theoretical and practical aspects of robust NI-PE (noninteractive polynomial evaluation with detection of cheaters). First, we give a necessary condition of adversary structures for which perfectly robust NI-PE with small communication complexity exists. More precisely, we show that for any positive integers n, m and d > 1, an n-player access structure U , and an...
