The sectoral composition of the US economy has changed dramatically in the past six decades. At the same time, knowledge and information assets are becoming increasingly important in the value creation process of a modern economy. This paper aims to explain the recent sectoral structural change...

This paper identifies a new mechanism leading to inefficiency in capital reallocation at theextensive margin when an economy experiences a sectoral boom. I argue that imperfectionsin the financial market and capital barriers to entry in the booming sector create amisallocation of managerial...

By examining two-sector models of endogenous growth with physical and human capital, this paper demonstrates that indeterminacy of equilibrium may emerge even in the absence of social increasing returns. The first model we examine assumes that both final good and new human capital production...

Satiation of need is generally ignored by growth theory. I study a model where consumers may be satiated in any given good but new goods may be introduced. A social planner will never elect a trajectory with long-run satiation. Instead, he will introduce enough new goods to avoid such a...

Using a new dataset on imports of technology and total factor productivity (TFP) over more than a century for the OECD countries, this paper tests for international technological transmission through trade. The empirical estimates suggest that imports of knowledge have been responsible for an...

In standard models wages are too volatile and returns too smooth. We make wages sticky through infrequent resetting, resulting in both (i) smoother wages and (ii) volatile returns. Furthermore, the model produces other puzzling features of financial data: (iii) high Sharpe Ratios, (iv) low and...

It seems to be taken for granted by many commentators that the sharp decline in prices of computers, telecommunications equipment and software resulting from the technological improvements in the information and communications technology (ICT)-producing sector is good for jobs and is a major...

Standard dynamic models of structural transformation, without knife-edge and counterfactual parameter values, preclude balanced growth path (BGP) analysis. This paper develops a dynamic equilibrium concept for a more general class of models | an alternative to a BGP, which we coin a Stable...

This paper revisits the canonical assumption of nonconvex capital adjustment costs in lumpy investment models as in Khan and Thomas (2008), which are assumed to follow a uniform distribution from zero to an upper bound, without distinguishing between the mean and the variance of the...
