Can a country grow faster by saving more? We address this question both theoretically and empirically. In our theoretical model, growth results from innovations that allow local sectors to catch up with frontier technology. In poor countries, catching up requires the cooperation of a foreign...

Can a country grow faster by saving more? We address this question both theoretically and empirically. In our model, growth results from innovations that allow local sectors to catch up with the frontier technology. In relatively poor countries, catching up with the frontier requires the...

This paper investigates the relationship between product market competition and innovation. We find strong evidence of an inverted-U relationship using panel data. We develop a model where competition discourages laggard firms from innovating but encourages neck-and-neck firms to innovate....

This paper investigates the relationship between product market competition (PMC) and innovation. A growth model is developed in which competition may increase the incremental profit from innovating; on the other hand, competition may also reduce innovation incentives for laggards. There are...

This paper focuses on how growth theory can guide growth policy design. It first argues that policy matters for growth, in particular when policy variables are interacted with country?specific variables (financial development, institutional environment, technological development, and so forth)....

Does education matter for growth? Which type of education investment (primary, secondary, or tertiary) matters most? Is there a relationship between growth or innovation and the governance of higher education? This paper surveys recent attempts at answering these questions. It first contrasts...

We develop a multi-tasking model in which a firm can devote its efforts either to increasing sales growth, or to improving per-unit profit margins by, e.g., cutting costs. If the firm's manager is concerned with the current stock price, she will tend to favor the growth strategy at those times...
