An identity links the rate of economic growth, the speed of poverty reduction and changes in the distribution of income during some time period in a given country. A few authors used that identity to understand the causes for observed changes in poverty and to identify the exact role of economic growth in poverty reduction. Yet, many empirical cross-country studies of the relationship between g...

We propose a theoretical model based on the bank lending channel to assess the ability of lending facilities and swap programmes to a¤ect the credit interest rate. The model predicts the success of both unconventional monetary measures in reducing the credit interest rate under very general conditions. The comparison between measures reveals the outperformance of lending facilities over swap pr...

We consider an economy where people have the needs for liquidity because of the unanticipated consumption opportunity, yet banks may not provide su¢ cient liquidity due to imperfect technology in commitment, enforcement and record-keeping. We show a link between the liquidity generated by bank lending, the value of the asset used as collateral and aggregate economic activity. When the record-ke...

I study a DSGE model incorporating a monetary transactions technology in which a representative household invests time to improve its skill (human capital) in making transactions. The model is designed to reconcile salient shortand long-run features of the relationship between money, income, and the opportunity cost of holding money. An econometric reduced form, derived analytically, is reveali...

This article adds technology choice to a free-entry Cournot model with linear demand and constant marginal costs. Firms can choose from a discrete set of technologies. This simple framework yields non-existence of equilibrium, existence of multiple equilibria and equilibria in which ex-ante identical ̄rms choose di®erent technologies as possible outcomes. I provide a full characterization of th...

We present a dynamic cash-management model where agents choose whether to pay with cash or credit at every point in time. In the model credit usage depends on the current stock of cash, a novel result that matches recent micro evidence on household’s payment choices. The optimality of such decision rule is novel and cannot be obtained by models where cash-credit decisions are made at the “begin...

We derive fundamental new theory for measuring monetary service flows aggregated over countries within a multicountry economic union. We develop three increasingly restrictive approaches: (1) the heterogeneous agents approach, (2) the multilateral representative agent approach, and (3) the unilateral representative agent approach. Our heterogeneous agents approach contains our multilateral repr...
