The Hall-Roeger methodology for the testing of market power is applied to Irish manufacturing industries for the period 1991-1999. The paper adapts their methodology to permit discrimination between input and output-price-based sources of market power. The empirical results do not indicate much evidence of significant imperfect competition in output markets but the results do point to evidence ...

Heat exchangers are one of the most important devices of mechanical systems in modernsociety. Most industrial processes involve the transfer of heat and more often they requirethe heat transfer process to be controlled. A heat exchanger is the heat exchanged betweentwo media, one being cold and the other being hot. There are different types of heatexchanger, but the type which is widely used in...

Rapid population growth, worsening of the climate, and severity of freshwater scarcity are global challenges. In Arab world countries, where water resources are becoming increasingly scarce, the recycling of industrial wastewater could improve the efficiency of freshwater use. The benchmarking of scientific output of industrial wastewater research in the Arab world is an initiative that could s...

ToToday’s market place is increasingly dynamic and volatile. In this area supply network issues recently have attracted a lot of attention from industrial practitioners and academics worldwide. Chaos theory is the study of complex, nonlinear, dynamic systems. For chaotic systems, a tiny change in conditions may result in an enormous change in system output, whereas substantial changes in condit...

Induction motors (IMs) are widely used in many industrial applications due to their robustness, low cost, simplicity and relative good efficiency. One of the major considerations for IMs is their speed control. PI (proportional-integrator) controllers are usually used as speed controller. Adjusting the gain of PI controller is time-consuming which needs thorough considerations. Hence, fuzzy con...

a r t i c l e i n f o This paper studies how financial development affects the volatility of GDP growth through the channel of sectoral reallocation. For 28 OECD countries over the period 1970–2007, we construct a benchmark industrial portfolio that minimizes the economy's long-term volatility for a given level of long-term labor productivity growth. We find that financial development substanti...

Utilization efficiency has been defined as the ratio of the amount of industrial roundwood (or wood pulp) consumed in a country and year to the amount that would have been consumed to produce the same output with a reference technology. The reference technology was described by the average input-output relationships in . countries of the Organization for Economic Cooperation and Development (OE...

In this paper, I present strong statistical evidence of the pervasiveness of official diversion in China’s industrial planning bureaucracy under the dual-track system. The underpricing of in-plan goods and the ensuing shortage in the plan led to gains from trade between officials who controlled the allocation of in-plan goods and customers willing to pay more than the plan prices. By diverting ...
