This paper investigates which properties money-demand functions have to satisfy to be consistent with multidimensional extensions of Lucas (2000) versions of the Sidrauski (1967) and the shopping-time models. We also investigate how such classes of models relate to each other regarding the...

This paper contributes to the micro-foundation of money in centralized markets with idiosyncratic uncertainty. It shows existence of stationary monetary equilibria and ensures that there is an optimum quantity of money. The rational solution of our model is compared with actual behavior in a...

We develop a dynamic general equilibrium model to analyze the effects of central bank purchases of government bonds by investigating the following three questions: Under what conditions are these purchases socially desirable, what incentive problems do they mitigate, and how large are these...

We develop a microfounded model, where agents have the possibility to trade money for government bonds in an over-the-counter market. It allows us to address important open questions about the effects of central bank purchases of government bonds, these being: under what conditions these...

We suggest the use of a particular Divisia index for measuring welfare losses due to interest rate wedges and inflation. Compared to the existing options in the literature: i) when the demands for the monetary assets are known, closed-form solutions for the welfare measures can be obtained at a...

This paper studies the welfare costs and the redistributive effects of inflation in the presence of idiosyncratic liquidity risk, in a micro-founded search-theoretical monetary model. We calibrate the model to match the empirical aggregate money demand and the distribution of money holdings...

I examine the robustness of monetary equilibria in a random matching model where a more efficient mechanism for trade is available. Agents choose between two trading sectors: the search and the intermediated sector. In the former, trade partners arrive randomly and there is a trading...
