Centralization Vs. Decentralization: First Evidence From The Laboratory, Gabriele Camera, Gary Charness, Nir Chemaya

ESI Working Papers

The future architecture of financial systems is a subject of contention, with centralized and decentralized governance proponents. Here we ask: would the architecture affect the quality of decision-making? We propose a game where financial network participants demarcate the ownership of claims to income. This governance task can be decentralized (shared authority), centralized (single authority), or hybrid (alternating authority). Without communication all architectures supported poor outcomes. With communication, decentralization ensured good governance and maximum profits, while centralization did not—lowering communication’s potency in promoting socially optimal decisions. This indicates there is scope for decentralization in innovating financial institutions.

Money And Social Exclusion In Networks, Maria Bigoni, Gabriele Camera, Edoardo Gallo

ESI Working Papers

Globalization offers unparalleled opportunities to expand welfare through cooperation across large networks of unrelated individuals. Social exclusion – permanent or temporary – and monetary exchange are institutions that in theory can incentivize cooperation. In an experiment, we evaluate their relative performance and interaction in anonymous networks of different sizes. Permanent social exclusion (ostracism) reduces long-run economic potential by leading to sparse networks. Monetary exchange and temporary social exclusion perform similarly well in small networks. In large networks, however, monetary exchange is the only institution that promotes full cooperation by crowding out ostracism and keeping the network complete. An insight is …

Nyc’S Boom: More Jobs And Housing, No Affordability, Lacandis Brown

Capstones

Although the number of NYC jobs is steadily growing faster than housing units are being created. Housing units are still being made in abundance, but residents say these new jobs just don't provide an adequate wage necessary to live within them.

Endogenous Market Formation And Monetary Trade: An Experiment, Gabriele Camera, Dror Goldberg, Avi Weiss

ESI Working Papers

The theory of money assumes decentralized bilateral exchange and excludes centralized multilateral exchange. However, endogenizing the exchange process is critical for understanding the conditions that support the use of money. We develop a “travelling game” to study the emergence of decentralized and centralized exchange, theoretically and experimentally. Players located on separate islands can either trade locally, or pay a cost to trade elsewhere, so decentralized and centralized markets can both emerge in equilibrium. The former minimize trade costs through monetary exchange; the latter maximizes overall surplus through non-monetary exchange. Monetary trade emerges when coordination is problematic, while centralized trade emerges …

Cryptocurrencies As An Alternative To Fiat Monetary Systems, David A. Georgeson

Applied Economics Theses

The recent popularity of cryptocurrencies is largely associated with a particular application referred to as Bitcoin. Cryptocurrency has a mix of properties that make it difficult to examine. These properties consist of being infinitely divisible, durable, transferable, fungible and can be controlled to be artificially scarce. Further, cryptocurrencies can act as a means of payment, a medium of exchange, a store of value, and a unit of account. This thesis will analyze the technical features underlying cryptocurrencies and find out whether or not they can function as an alternative to fiat money. Since Bitcoin is the most commonly understood application …

Endogenous Market Formation And Monetary Trade: An Experiment, Gabriele Camera, Dror Goldberg, Avi Weiss

ESI Working Papers

The theory of money assumes decentralized bilateral exchange and excludes centralized multilateral exchange. However, endogenizing the exchange process is critical for understanding the conditions that support the use of money. We develop a “travelling game” to study the spontaneous emergence of decentralized and centralized exchange, theoretically and experimentally. Players located on separate “islands” can either trade locally, or pay a cost to trade elsewhere, so decentralized and centralized markets can both emerge in equilibrium. The latter maximize trade meetings and are socially efficient; the former minimize trade costs through the use of money. In the laboratory, centralized exchange more frequently …

An Experiment On Retail Payments Systems, Gabriele Camera, Marco Casari, Stefania Bortolotti

ESI Working Papers

We develop a novel theoretical and experimental framework to study adoption and use of cash versus electronic payments in retail transactions. The design allows us to assess the behavioral impact of sellers’ service fees and buyers’ rewards from using electronic payments. In the experiment, buyers and sellers faced a coordination problem, independently choosing a payment method before trading. Sellers readily adopted electronic payments but buyers did not. Eliminating service fees or introducing rewards significantly increased adoption and use of electronic payments. Buyers’ economic incentives played a pivotal role in the diffusion of electronic payments but cannot fully explain their adoption …

Understanding The Distributional Impact Of Long-Run Inflation, Gabriele Camera, Yili Chen

Economics Faculty Articles and Research

The impact of fully anticipated inflation is systematically studied in heterogeneous agent economies with an endogenous labor supply and portfolio choices. In stationary equilibrium, inflation nonlinearly alters the endogenous distributions of income, wealth, and consumption. Small departures from zero inflation have the strongest impact. Three features determine how inflation impacts distributions and welfare: financial structure, shock persistence, and labor supply elasticity. When agents can self-insure only with money, inflation reduces wealth inequality but may raise consumption inequality. Otherwise, inflation reduces consumption inequality but may raise wealth inequality. Given persistent shocks and an inelastic labor supply, inflation may raise average welfare. …

Money Is Time: The Monetary Expression Of Value In Marx's Theory Of Value, David Kristjanson-Gural

Faculty Journal Articles

In this article, I derive the monetary expression of value based upon commodity money and use it to translate values and exchange values from units of labor into units of money. While this analysis has been done at the initial stage of Marx’s analysis where he assumes that commodities exchange in proportion to their values, I derive the monetary expression of value at the more developed stage of Marx’s 10 analysis where commodities exchange according to prices of production. I then develop a macroeconomic measure of the monetary expression of value and link the micro- and macroeconomic determination of the …

Another Example Of A Credit System That Coexists With Money, Gabriele Camera, Yiting Li

Economics Faculty Articles and Research

We study an economy in which exchange occurs pairwise, there is no commitment, and anonymous agents choose between random monetary trade or deterministic credit trade. To accomplish the latter, agents can exploit a costly technology that allows limited recordkeeping and enforcement. An equilibrium with money and credit is shown to exist if the cost of using the technology is sufficiently small. Anonymity, record-keeping and enforcement limitations also permit some incidence of default, in equilibrium.

The Distribution Of Money And Prices In An Equilibrium With Lotteries, Aleksander Berentsen, Gabriele Camera, Christopher Waller

Economics Faculty Articles and Research

We construct a tractable ‘fundamental’ model of money with equilibrium heterogeneity in money balances and prices. We do so by considering randomized monetary trades in a standard search-theoretic model of money where agents can hold multiple units of indivisible ‘tokens’ and can offer lotteries on monetary transfers. By studying a simple trading pattern, we can analytically characterize the monetary distribution. Interestingly, such distributions match those observed in numerically simulated economies with fully divisible money and price heterogeneity.
