We analyze how expropriation risk reduces incentives for innovation and reallocates resources from the innovative sector, building on Romer's(1990) model. Our framework predicts the R&D expenditure, the share of human capital in R&D, the number of patents, technical progress, and economic growth...

The nonrivalry of ideas gives rise to increasing returns, a fact celebrated in Paul Romer's recent Nobel Prize. An implication is that the long-run rate of economic growth is the product of the degree of increasing returns and the growth rate of research effort; this is the essence of...

This paper investigates a unique policy designed to maintain employment during the privatization of East German firms after the fall of the Iron Curtain. The policy required new owners of the firms to commit to employment targets, with penalties for non-compliance. Using a dynamic model, we...

This paper evaluates the impact of slowing economic growth on labor market dynamism and misallocation. It provides a model of endogenous growth via imitation in a frictional labor market. The framework accounts for rich data on worker job-to-job transitions as well as stochastic and lifecycle...

We quantify the real implications of trade-offs between firm information disclosure and long-term investment efficiency. We estimate a dynamic equilibrium model in which firm managers confront realistic incentives to misreport earnings and distort their real investment choices. The model implies...

Technological advance is often embodied in capital inputs. This paper develops a model where capital innovations occur on two margins: (1) vertically, where a capital input becomes more productive at a given task; and (2) horizontally, where a capital input replaces labor at a given task. These...

Does capital accumulation increase labor demand and wages? Neoclassical production functions, where capital and labor are q-complements, ensure that the answer is yes, so long as labor markets are competitive. This result critically depends on the assumption that capital accumulation does not...

Foresightful workers can take actions to reduce their exposure to risk in labor markets, but existing evidence on narrow bracketing suggests that individuals might not optimally integrate risk reduction decisions with subsequent labor decisions. In an online labor market, we vary the level of...
