We build an endogenous growth model with automation (the replacement of low-skill workers machines) and horizontal innovation creation new products). Over time, the share innovations endogenously increases through increase in wages, leading to skill premium a decline labor share. calibrate US economy show that it quantitatively replicates paths premium, share, productivity. Our offers perspecti...

This paper considers a neoclassical optimal growth problem where the shock that perturbs the economy in each time period is potentially unbounded on the state space. Sufficient conditions for existence, uniqueness and stability of equilibria are derived in terms of the primitives of the model using recent techniques from the field of perturbed dynamical systems.

The paper proposes an Euler equation technique for analyzing the stability of differentiable stochastic programs. The main innovation is to use marginal reward directly as a Foster–Lyapunov function. This allows us to extend known stability results for stochastic optimal growth models, both weakening hypotheses and strengthening conclusions. JEL classification: C61; C62; O41

The interaction between income distribution, accumulation, employment and the utilization of capital is central to macroeconomic models in the `heterodox' tradition. This paper examines the stylized pattern of these variables using US data for the period after 1948. We look at the trends and cycles in individual time series and examine the bivariate cycical patterns among the variables. JEL cla...
