I study the effects of long-run inflation and income taxation in an economy where households face uninsurable idiosyncratic risks. I construct a tractable competitive search framework that generates dispersion of prices, income and wealth. I analytically characterize the stationary equilibrium...

We develop a Shumpeterian theory of business cycles that relates job creation, job destruction and wages over the cycle to the processes of firm restructuring, innovation and implementation that drive long-run growth. Due to incentive problems, production workers are employed via relational...

We develop a dynamic general equilibrium model of economics development with altruism in which the evolution of the extent of entrepreneurship, the rate of rural-urban migration, the scale and structure of production and the degree of income and wealth inequality are endogenously determined. The...

We use a Schumpeterian model in which both the economy's growth rate and its volatility are endogenously determined to assess some welfare and policy implications associated with business cycle fluctuations. Because it features a higher average growth rate than its acyclical counterpart,...

We develop a model of "intrinsic" business cycles, driven by the decentralized behaviour of entrepreneurs and firms making continuous, divisible improvements in their productivity. We show how equilibrium cycles, associated with strategic delays in implementation and endogenous innovation, arise...

Dispersion of money balances among individuals is the basis for a range of policies but it has been abstracted from in monetary theory for tractability reasons. In this paper, we fill in this gap by constructing a tractable search model of money with a non-degenerate distribution of money...

This paper presents an integrated theory of money and banking. I address the following question: when both individuals and banks have private information, what is the optimal way to settle debts? I develop a dynamic model with micro-founded roles for banks and a medium of exchange. I establish...

This paper studies bank runs in a model with coexistence of fiat money and private money. When fiat money is the only medium of exchange, there exist a bank run equilibrium and an equilibrium that achieves the optimal risk sharing. In contrast, when private money is also a medium of exchange,...

This paper derives a key monotonicity property common to dividend signalling models: the greater the rate that dividend income is taxed relative to capital gains income, the greater the value of information revealed by a given dividend yield, and hence the greater the associated excess return....

We study the trading dynamics in an asset market where the quality of assets is private information of the owner and finding a counterparty takes time. When trading of a financial asset ceases in equilibrium as a response to an adverse shock to asset quality, a large player can resurrect the...
