Ordinally single-peaked preferences are distinguished from cardinally single-peaked preferences, in which all players have a similar perception of distances in some one-dimensional ordering. While ordinal single-peakedness can lead to disconnected coalitions that have a "hole" in the ordering,...

The paper puts forward the hypothesis that transitory effects of trade liberalization on wage inequality can differ from the long-run outcome based on the HOS theory. In cases where HOS theory predicts a decline in wage inequality in the long run, a temporary rise can occur due to (i)...

Ordinally single-peaked preferences are distinguished from cardinally single-peaked preferences, in which all players have a similar perception of distances in some one-dimensional ordering. While ordinal single-peakedness can lead to disconnected coalitions that have a "hole" in the ordering,...

For the economic sciences, mainly for the planning and organization disciplines, the models display a range of varieties. For the last decades, though, the mathematics-based models seem to be the trend, partly because of their ability to rigorously concentrate the essentials and also to be...

The standard economic model for analyzing traffic congestion, due to A.A. Walters, incorporates a relationship between speed and traffic flow. Empirical measurements indicate a region, known as hypercongestion, in which speed increases with flow. We argue that this relationship is unsuitable as...

Fruit production and consumption have increased considerably in the past few decades in Taiwan. Market prices of fruits fluctuate in response to seasonality, changes in production costs, imports and exports, and demand. Some factors are more influential to fruit price changes. This research...
