We examine equilibration in a market where Marshallian path adjustment can be enforced, or not, as a treatment: a posted offer market either with buyer queueing via value order, or random order, respectively. We derive equilibrium predictions, and run experiments crossing queueing rules with...

The paper discusses the utilization of social complexity studies to enhance our understanding on many social phenomena. The discussions brings the concept of uncertainty in almost everything of social realms and makes some points related to the empirical findings of the power-law distributions...

The present study constructs a decision support system to determine the best seeding rate out of a group of seeding rates applied in the field. The DSS has been built receives the field data as inputs, and then apply split plot algorithms of (Gomez & Gomez, 1984) to find the results. These...

In countries where tools of economic control are immature and disabled due to totalitarian systems, macroeconomic analyses for aggregate quantities and relationships, such as total consumption, investment, and government expenditures represents a difficult task. The practice of aggregation...

In the first meta-study on the finance-growth nexus, we bridge the gap between Schumpeterian authors and sympathizers of Andersen & Tarp (2003). Over 20 fundamental characteristics that have influenced the debate over the last decades are examined. The empirical evidence is based on 196 outcomes...

Resource misallocation can lower aggregate total factor productivity (TFP).We use microdata on manufacturing establishments to quantify the potential extent of misallocation in China and India versus the United States. We measure sizable gaps in marginal products of labor and capital across...

The present study reviews the determination of the crop yield issues. Data analysis and utilization in the determination is essential for better production and economic performance. We follow the method of Williamson (1988) in discussing those issue and briefly compare them to application in Sudan.

The present study constructs a decision support system to determine the best seeding rate out of a group of seeding rates applied in the field. The DSS has been built receives the field data as inputs, and then apply split plot algorithms of (Gomez & Gomez, 1984) to find the results. These...

In recent years, the government, of African Countries has assumed major responsibilities for economic reforms and growth. In attempting to describe their economies, economists (policymakers) in many African Countries have applied certain models that are by now widely known: Linear programming...
