Harmful Procompetitive Effects of Trade in Presence of Credit Market Frictions

We explore the consequences of international trade in an economy that encompasses technology choice and an endogenous distribution of mark-ups due to credit market frictions. We show that in such an environment a gradual opening of trade may—but not necessarily must—have a negative impact on productivity and overall output. The reason is that the procompetitive effects of trade reduce mark-ups and hence make access to credit more difficult for smaller firms. As a result, smaller firms—while not driven out of the market—may be forced to switch to less productive technologies.     

Income Distribution and Demand-Induced Innovations

We introduce non-homothetic preferences into an innovation-based growth model and study how income and wealth inequality affect economic growth. We identify a (positive) price effect—where increasing inequality allows innovators to charge higher prices and (negative) market-size effects—with higher inequality implying smaller markets for new goods and/or a slower transition of new goods into mass markets. It turns out that price effects dominate market-size effects. We also show that a redistribution from the poor to the rich may be Pareto improving for low levels of inequality.
