We develop a New Monetarist model with expenditure and unemployment risks that generates equilibria with non-degenerate distribution of money holdings. Distributional effects can overturn key insights of the model with degenerate distributions, e.g., the value of money depends on the income...

We construct a tractable model of monetary exchange with search and bargaining that features a non- degenerate distribution of money holdings in which one can study the short-run and long-run effects of changes in the money supply. While money is neutral in the long run, a one-time money...

We construct a continuous-time, pure currency economy with the following three key features. First, our modelled economy incorporates idiosyncratic uncertainty--households receive infrequent and random opportunities of lumpy consumption--and displays an endogenous, non-degenerate distribution of...

Income disparity across countries has been large and widening over time. We develop a tractable model where factor requirements in production technology do not necessarily match a country's factor input profile. Appropriate assimilation of frontier technologies balances such multi-dimensional...

How large is the impact of artificial intelligence (AI) on labor productivity and unemployment? This paper introduces a labor-search model of technological unemployment, conceptualizing the generative aspect of AI as a learning-by-using technology. AI capability improves through machine learning...

We develop a model of a two-sided asset market in which trades are intermediated by dealers and are bilateral. Dealers compete to attract order flow by posting the terms at which they execute trades-- which can include prices, quantities, and execution speed--and investors direct their orders...

We study an over-the-counter (OTC) market with bilateral meetings and bargaining where the usefulness of assets, as means of payment or collateral, is limited by the threat of fraudulent practices. We assume that agents can produce fraudulent assets at a positive cost, which generates endogenous...

We study the efficiency of dealers' liquidity provision and the desirability of policy intervention in over-the-counter (OTC) markets during crises. Our theory emphasizes two key frictions in OTC markets: finding counterparties takes time, and trade is bilateral, with quantities and prices...

We study the dynamics of liquidity provision by dealers during an asset market crash, described as a temporary negative shock to investors aggregate asset demand. We consider a class of dynamic market settings where dealers can trade continuously with each other, while trading between dealers...
