We explain a counterintuitive empirical finding: Firms facing more import competition do more innovation. In our model, factors are trapped inside a firm. An increase in import competition encourages a firm to innovate by reducing the opportunity cost of inputs. Without trapped factors, trade...

Sunk costs for R&D are an important determinant of the level of innovation in the economy. In this paper I recover them using a Markov equilibrium framework. The contribution is twofold. First, a model of industry dynamics which accounts for selection into R&D, capital accumulation and...

In the Former Soviet Union, the early 1990s were characterized by large falls in GDP and small changes to already low unemployment. The slow adjustment to unemployment was a result of employers using various means to maintain employment levels, including; extended periods of unpaid leave,...

In the wake of the financial crisis output fell dramatically while inflation remained above its target and productivity collapsed relative to its previous trend. The fall in productivity relative to trend was particularly pronounced within the service sector, and then most particularly in...

We examine how cheap talk communication between managers within the same firm depends on the type of decisions that the firm makes. A firm consists of a headquarters and two operating divisions. Headquarters is unbiased but does not know the demand conditions in the divisions' markets. Each...

We estimate the impact of a carbon tax on manufacturing plants using panel data from the UK production census. Our identification strategy builds on the comparison of outcomes between plants subject to the full tax and plants that paid only 20% of the tax. Exploiting exogenous variation in...

This paper develops a model of endogenous product selection by firms. The theory is motivated by new evidence we present on the importance of product switching by U.S. manufacturers. Two-thirds of continuing firms change their product mix every five years, and product switches involve more than...

We estimate the impacts of an energy tax – the Climate Change Levy (CCL) – on the manufacturing sector using panel data from the UK production census. Our identification strategy builds on the comparison of trends in outcomes between plants subject to the CCL and plants that were granted an...

Individuals and business owners engage in an increasingly complex array of financial decisions that are critical for their success and well-being. Yet a growing literature documents that in both developed and developing countries, a large fraction of the population is unprepared to make these...

This paper shows that increasing product market competition can have a direct impact on the employment relationship and on wage inequality. I develop a simple model in which an increase in product market competition increases returns to skill through the effect of competition on the sensitivity...
