Capital Accumulation, the Organic Composition of Capital, the Rate of Profit and the Rate of Exploitation in a Provisional Marxian Model

Marglin's neo-Marxian one sector model with continuous substitution is amplified by adding land as a factor of production and technical progress and specialized by using a specific production function and the most simple of saving functions. It is then shown that, under a simple condition on the production function, the accumulation of capital eventually causes the organic composition of capital to rise, the rate of profit to fall and the rate of exploitation to rise.
