We investigate how banking relationships that combine lending and underwriting services affect the terms of lending, through both loan supply- and loan demand-side effects, and the underwriting costs of debt and equity issues. We capture and control for firm characteristics, including...

A binding interest rate cap on household savings is a common form of financial repression in developing economies and typically benefits banks. Using proprietary data from a leading Chinese FinTech company, we study Fintech's role in ending financial repression in China through the introduction...

Product redesigns happen across virtually all types of products. While there is substantial evidence that new varieties of goods increase welfare, there is little evidence on the effect of product redesigns. We develop a model of redesign and exit decisions in a dynamic oligopoly model (a la...

We analyze entry, pricing and product design in a model with differentiated products. Under plausible conditions, entry into an initially monopolized market leads to higher prices for some, possibly all, consumers. Entry can induce a misallocation of goods to consumers, segment the market in a...

We develop a model of repeated product improvements in a continuum of sectors. Each product follows a stochastic progression up a quality ladder. Progress is not uniform across sectors, so an equilibrium distribution of qualities evolves over time. But the rate of aggregate growth is constant....

Thereare three points made in this paper. The first is that the question concerning choice of a product line by a monopolist is similar in structure to other adverse selection problems -- and can be analyzed in an elementary way by adapting techniques recently developed for such problems. Such...

This paper shows that product design shapes search frictions and that intermediaries leverage this channel to increase their rents in the context of the U.S. municipal bond market. The majority of bonds are designed via negotiations between a local government and its underwriter. They are then...

Digital finance in agriculture is a nascent technology which could help improve rural financial inclusion. In an experimental evaluation of a digital lending product for farmers in Southern Ghana, credit increases farm investments but has few statistically significant average effects on...

A growing body of rigorous research shows that financial services innovations can have important positive impacts on wellbeing, but also that many do not. We first describe the latest evidence on what works in financial inclusion. Second, we summarize research on key financial market failures...
