This paper shows that aggregation over heterogeneous firms, which are subject to temporary technology shocks, will lead to long memory and nonlinearities. We start from microfoundations, using standard RBC model of monopolistic competition. We then derive the fundamental intertemporal...

Suppose we have observations ranging over t = 0; 1;... T on real net investment, {In;t} , and on real gross investment, {Ig;t}. We derive a method of calculating the depreciation rate for each of the periods {delta t} , and estimating `the' implied net capital stock {Kt}. We then provide empirical...

This paper examines choice of occupation between productive activities and rent-seeking in an oil-dominated economy where oil rent is the major source of public revenue. Three regimes can occur: no rent-seeking, coexistence of rent-seeking and of productive activity and full rent-seeking. The...

This paper studies the implications of state pension plan reform on fertility and on growth. It extends the Grossman and Yanagawa (1993) endogenous growth framework by incorporating altruism, making fertility endogenous. We investigate the effect on long-run growth of a switch from a...

We study the optimal choice of quasi-likelihoods for nearly integrated, possibly non-normal, autoregressive models. It turns out that the two most natural candidate criteria, minimum Mean Squared Error (MSE) and maximum power against the unit root null, give rise to different optimal...
