We study the effects of technological change on financial intermediation, distinguishing between innovations in information (data collection and processing) and communication (relationships and distribution). Both follow historic trends towards an increased use of hard information and less...

The interaction between credit frictions, financial innovation, and a switch from optimistic to pessimistic beliefs played a central role in the 2008 financial crisis. This paper develops a quantitative general equilibrium framework in which this interaction drives the financial amplification...

Financial innovation has increased diversification opportunities and lowered investment costs, but has not reduced the relative cost of active (informed) investment strategies relative to passive (less informed) strategies. What are the consequences? I study an economy with linear production...

This paper examines the welfare effects of mitigating the costs of inflation. In a simple model where money reduces transaction costs, a fall in the costs of inflation is equivalent to financial innovation. This can be caused by paying interest on deposits, indexing money, or “dollarizing.”...

This paper presents a cash-in-advance framework, with variable income velocity, where the domestic effects, as well as the international transmission, of financial innovation can be analyzed. In particular, the discussion emphasizes the role of currency substitution and of cross-border transfers...

In short, yes. I use a multi-region integrated assessment model with fuel-specific endogenous technical change to examine the impact of Europe and China reducing emissions to zero by mid-century. Without international technological diffusion this is insufficient to avoid catastrophic climate...

Intangible investment is growing as a share of economic activity. We present a simple framework incorporating its distinguishing characteristic of generally greater scalability and lower marginal costs than tangible investment. We show evidence that this may have contributed to more elastic...

It takes many years for more efficient electronic payments to be widely used, and the fees that merchants (consumers) pay for using those services are increasing (decreasing) over time. We address these puzzles by studying payments system evolution with a dynamic model in a twosided market...

Based on stylized evidence showing variation of the Gini coefficient of income inequality across skill cohorts and on the rapid rise in trade in technology-intensive goods, the ripple effects of technology transmission and income inequality are explored in a global Computable General Equilibrium...
