The effect of labor quality on labor's factor share

Assessing productivity, cost, and delays are essential to manage any construction operation, particularly the concrete batch plant (CBP) operation. This paper focuses on assessing the above-mentioned items for the CBP using stochastic mathematical models. It aims at (i) identifying the potential sources of delay in the CBP operation; (ii) assessing their influence on production, efficiency, time, and cost; and (iii) determining each factor share in inflating the CBP concrete unit expense. Stochastic mathematical models were designed to accomplish the aforementioned objectives. Data were collected from five CBP sites in Indiana, USA, to implement and verify the designed models. Results show that delays due to management conditions have the highest probability of occurrence (0.43), expected value of delay percent (62.54% out of total delays), and relative delay percent. The expected value of efficiency for all plants is 86.53%; however, the average total expense is US$15.56/m3 (all currency are in US$). In addition, the expected value of effective expenses (EE) is $18.03/m3, resulting in extra expenses (XE) of $2.47/m3. This research is relevant to both industry practitioners and researchers. It develops models to determine the effect of delays on concrete unit cost. They are also beneficial to the CBP management.Key words: concrete batch plant, delays, management conditions, cost models, cost management, stochastic mathematical models.

Enhance Efficiency

By estimating stochastic frontiers we investigate the determinants and dynamics of firm efficiency. We use a representative sample of Estonian firms for the period 1993-1999 – and are able to address problems that plague much previous work, such as the endogeneity of ownership. Our main findings are that: (i) foreign ownership increases technical efficiency; (ii) firm size and higher labor quality enhance efficiency, while soft budget constraints adversely affect efficiency; (iv) Estonian firms operate under constants returns to scale; (v) the percentage of firms operating at high levels of efficiency increases over time. As such our findings provide support for hypotheses that a firm’s ownership structure and its characteristics such as firm size, labor quality, soft budget constraints and time of privatization are important for its technical efficiency.

In this article, I report results of an exploratory data analysis that challenge the conventional wisdom on the relation between computer use and gender wage. Using the micro-economic data of 1984, 1993, and 2001, I find 1) the wage premium for females using computers at work is about 19-26 per cent higher than males within the high bluecollar sector, and 2) college-educated females who use computers at work earn a substantially higher wage than college-educated males. These results indicate that computers have re-structured work by deemphasizing physical skill that benefits women, and that college- educated women in the white-collar sector have unobserved female labor quality that could positively correlate with computer skill.

There are 3 phenomens of most economic which undivided that openess and international trade and economic growth. Openess is the first frame for most country to do consolidation for its capability and weakness. International trade have able support high economic growthsignificantly. This paper would like to inform us about development of international economic from Classical Economic era to Modern International Economic (integration of endogenous growth and trade). The analyzis is not only comparative static approach but alsointertemporal approach. Scientificly the country’s advantage of modern international trade is not only analyzed for technology and specialization but also countries’s factor share. Generally, all countries tend to the long term equilibrium in the balance growth path.Therefore, each country and rest of the world will able to meet welfare economy not only individually but also international.Keywords: Technology, International Trade, Economic Growth, Balance Growth Path, Factor Share, Total Productivity, Bang-Bang Control.
