Acemoglu’s (2003) paper “Labor- and Capital-augmenting Technical Change” is a pioneering work that introduces a growth model with an endogenous direction of technical progress including microfoundations. At the steady-state equilibrium, the model indicates that there is only net...

Based on a general growth model, this paper finds that the steady-state direction of technological progress is determined by the scale return of the production function and the relative factor supply elasticities. A specific version of that model extends Acemoglu (2002) to provide the underlying...

In a classic paper, Acemoglu (2003) developed a growth model where firms can undertake both labor- and capital-augmenting technological improvements. According to that paper the balanced growth path with purely labor-augmenting technical change is the unique asymptotic (noncycling) equilibrium,...

The history of modern economic growth indicates that technical change is not only purely labor-augmenting, but also skill biased the 20th century. Although there are papers that have separately analyzed why technical change be purely labor-augmenting or skill biased, there is no paper analyzing...

The neoclassical Euler equation provides the necessary conditions for households to maximize lifetime utility by allocating income between consumption and investment, and is the core equation for solving the steady-state of the neoclassical growth model. The existing textbooks (Barro and...

Technological progress relates not only to its rate but also to its direction and bias. The rate has been analyzed by the endogenous technical change models and the bias has been analyzed by the directed technical change model, but the determinants of the direction has not been uncovered yet....

The celebrated Uzawa(1961) theorem holds that，on the steady-growth path of neoclassical growth model，technological progress must be purely labor-augmenting rather than capital-augmenting，except the special case where the production function takes the form of Cobb-Douglas. With an augmented...

Since the publication of Uzawa(1961), it has been widely accepted that technical change must be purely labor-augmenting for a growth model to exhibit steady-state path. But in this paper, we argue that such a constraint is unnecessary. Further, our model shows that, as long as the sum of the...

Taking into account the adjustment costs of investment, this paper proves that it is not the neoclassical growth model itself but the specific form of capital accumulation function that requires technical change to exclusively be Harrod neutral in steady state. Uzawa’s(1961)steady-state growth...

This paper proves that there is a similar Uzawa (1961) steady-state growth theorem in a Malthusian model: If that model possesses steady-state growth, then technical change must be purely land-augmenting and cannot include labor augmentation.
