Tools utilized included descriptive statistics, budgetary and cash flow analyses and profitability ratios. Empirical results revealed that substantial revenue could be realized from both farms. While the upland farms yielded average gross reven...

Conservation agriculture (CA) practices are being widely promoted in many areas in sub-Saharan Africa to recuperate degraded soils and improve ecosystem services. This study examined the effects of three tillage practices [conventional moldboard plowing (CT), hand hoeing (MT) and no-tillage (NT)], and three cropping systems (continuous maize, soybean-maize annual rotation, and soybean/maize int...

A user-friendly computerized decision model has been developed for selecting profitable site-specific herbicide applications in winter wheat. The model is based on six years of field research in southeastern Washington State, USA. The model calibrates herbicide applications to management unit weed densities, soil organic matter, soil moisture, and preceding management, as well as to expected in...

After analyzing retail investors’ stock trades for potential learning behavior, we present evidence that individual investors learn from their trading experience. Initially, we question whether investors’ previous forecasting ability (inferred from prior purchases’ subsequent risk-adjusted performance) affects their future trade profitability and activity. Indeed, as an investor’s inferred abil...

The growth cycle and labour contract length This paper extends the growth cycle model à la Goodwin (1967) by introducing the risk-averse behaviour of the agents and a consequent positive correlation between wages and profitability.
