The purpose of this paper is to focus on labor movement in the agricultural sector of Taiwan to clarify the relationship between agricultural policy and the agricultural adjustment problem by estimating the labor movement function.

The relationship between agricultural policy and the adjustment process of agricultural labor in Taiwan was analyzed by modeling labor movement between the agricultural sector and other sectors. Through empirical analysis of labor migration function, it is clear that the following policy factors, affect the incentive for labor migration, and obstruct off‐farm labor migration: the price support policy; the incomplete farmland conversion regulations, which increase farmers' farmland possession motive; and government agricultural expenditure, which includes direct transfers to the agricultural sector.

The study confirms that after the late 1980s the factors that obstruct agricultural adjustment much more than the price support policy are the incomplete farmland conversion regulations and increasing government agricultural payments, from the result of the simulation with the influence of the policy eliminated.

The implication of this paper is that even though Taiwan has been participating in World Trade Organization from 2002 and consented to cut the tariff on agricultural products and reduce agriculture support policies not linked to production, a delay in labor adjustment between the agricultural sector and other sectors may not necessarily be eliminated if there are other policy factors that affect the incentive for off‐farm migration by farmers.

Many studies use the labor migration function for empirical analysis, but most of them estimated the function by a simple single regression which shows that the labor movement from the agricultural sector to the other sectors increases as a result of an expanding wage gap. However, off‐farm labor movement reduces the wage gap between sectors adversely. Therefore, a reverse causal relation exists between labor movement and the wage gap between sectors. The endogeneity problem was considered as analyzing the measurement of the labor migration function.

The emergence of the systolic paradigm in 1978 inspired the first 2D‐array parallelization of the sequential matrix multiplication algorithm. Since then, and due to its attractive and appealing features, systolic approach has been gaining great momentum to the point where all 2D‐array parallelization attempts were exclusively systolic. As good result, latency has been successively reduced a number of times (5N, 3N, 2N, 3N/2), where N is the matrix size. But as latency was getting lower, further irregularities were introduced into the array, making the implementation severely compromised either at VLSI level or at system level. The best illustrative case of such irregularities are the two designs proposed by Tsay and Chang in 1995 and considered as the fastest designs (3N/2) that have been developed so far. The purpose of this paper is twofold: we first demonstrate that N+√N/2 is the minimal latency that can be achieved using the systolic approach. Afterwards, we introduce a full‐parallel 2D‐array algorithm with N latency and 2N I/O‐bandwidth. This novel algorithm is not only the fastest algorithm, but is also the most regular one too. A 3D parallel version with O(log N) latency is also presented.
