Abstract We study price posting with undirected search in a search-theoretic monetary model with divisible money and divisible goods. Ex ante homogeneous buyers experience match specific preference shocks in bilateral trades. The shocks follow a continuous distribution and the realization of the shocks is private information. We show that generically there exists a unique price posting monetary equilibrium. In equilibrium, each seller posts a continuous pricing schedule that exhibits quantity discounts. Buyers spend only when they have high enough preferences. As their preferences are higher, they spend more till they become cash constrained. Since inflation reduces the future purchasing power of money and the value of retaining money, buyers tend to spend their money faster in response to higher inflation. In particular, more buyers choose to spend money and buyers spend on average a higher fraction of their money. The model naturally captures the hot potato effect of inflation along both the intensive margin and the extensive margin. Résumé Les auteures étudient le comportement d'acheteurs qui ne peuvent observer les prix affichés qu'après leur appariement à un vendeur, dans le cadre d'un modèle théorique de prospection monétaire caractérisé par la divisibilité de la monnaie et des biens. Les préférences des acheteurs, considérés a priori comme homogènes, font l'objet de chocs durant les rencontres bilatérales avec le vendeur. Ces chocs suivent une loi de distribution continue et leur réalisation constitue une information connue des seuls acheteurs. Les auteures montrent qu'il existe de façon générale un équilibre monétaire unique pour les prix affichés. À l'équilibre, chaque vendeur affiche une série continue de prix assortis de rabais sur les quantités. Les acheteurs ne dépensent que si leurs préférences sont suffisamment fortes, et plus leurs préférences s'élèvent, plus ils consomment, jusqu'à épuisement de leurs fonds. Puisque l'inflation diminue le pouvoir d'achat futur ainsi que l'intérêt qu'il y a à conserver de l'argent, les acheteurs sont portés à dépenser plus rapidement lorsque l'inflation augmente. En particulier, un plus grand nombre d'acheteurs décident de dépenser et ils dépensent en moyenne une part accrue de la monnaie en leur possession. Le modèle parvient à recréer l'effet de délestage causé par la hausse de l'inflation, tant dans sa dimension …

Price dispersion, information and learning
We consider an economy where trade is decentralized and agents have incomplete information with respect to the value of money. Agents’ learning evolves from private experiences and we explore how the formation of prices interacts with learning. We show that multiple equilibria arise, and equilibria with price dispersion entail more learning than equilibria with one price. Price dispersion incre...
متن کاملCrypto Currencies and the Blockchain Technology: An Evolutionary Review of Money and the Payment Systems
In this paper we utilize the main findings from the recent literature to set the economic foundation for the existence of money, its modern interpretation as “memory” (Chokerlakota 1998) and how the Blockchain technology has empowered crypto currencies to perform this role in the information age. To locate the issue in a historical perspective and in line with this strand of thought, we consid...
متن کاملInflation and Welfare in Models with Trading Frictions∗
We study the effects of inflation in models with various trading frictions. The framework is related to recent search-based monetary theory, in that trade takes place periodically in centralized and decentralized markets, but we consider three alternative mechanisms for price formation: bargaining, price taking, and posting. Both the value of money per transaction and market composition are end...
متن کاملPricing and signaling with frictions
We study a large market with directed search and signaling. Each seller chooses an investment that determines the quality of the good which is the seller’s private information. A seller also chooses the price of the good and the number of selling sites. After observing sellers’ choices of prices and sites, but not quality, buyers choose which site to visit. The sites posting the same price and ...
متن کاملMoney in Search Equilibrium, in Competitive Equilibrium, and in Competitive Search Equilibrium∗
We compare three pricing mechanisms for monetary economies: bargaining (search equilibrium); price taking (competitive equilibrium); and price posting (competitive search equilibrium). We do this in a framework that, in addition to considering different mechanisms, extends existing work on the microfoundations of money by allowing a general matching technology and endogenous entry. We study how...
