This paper theoretically studies the consequences of heterogeneity on self-governance, cooperation, and trust in large communities. I consider a game model where players belong to a large population and are randomly matched. Players interact with each other infrequently and, when matched, play a prisoners’ dilemma. There exists an institution that can convey information on play histories. Playe...

Recently, a growing literature, known as the new classical economics, attempts to resurrect the classical economic thoughts on division of labor within an analytical framework inherited from neoclassical economics. The paper inspects the feasibility of this approach and finds that the current analytical framework of the new classical economics is not able to spell out how individuals’ decisions...

We study an ascending auction of an indivisible good in which agents observe multidimensional Gaussian signals about their valuation of the good. The equilibrium is solved using a two-step procedure. The first step is to project the signals into a one-dimensional equilibrium statistic. The second step is to solve for the equilibrium as if agents observed only the equilibrium statistic (and henc...

Racial and Ethnic Discrimination in Local Consumer Markets: Exploiting the Army’s Procedures for Matching Personnel to Duty Locations We use the exogenous assignment of Army personnel to duty locations to analyze the relationship between the characteristics of local markets and the propensity for consumers to be subjected to racial discrimination in their everyday commercial transactions. Overa...

Soil profiles were collected at a depth of 30 cm in ditch wetlands (DWs), riverine wetlands (RiWs) and reclaimed wetlands (ReWs) along a 100-year chronosequence of reclamation in the Pearl River Delta. In total, 16 OCPs were measured to investigate the effects of wetland reclamation and reclamation history on OCP levels. Our results showed that average ∑DDTs, HCB, MXC, and ∑OCPs were higher in ...

It is customary to analyze transport industry structure using two indices: economies of density and economies of scale with variable network size (RTS). The latter has been defined to analyze the behavior of costs when output and network size expand simultaneously. After reviewing in detail what is intended with the calculation of RTS under this definition, we show analytically that, when the s...

When consumers do not know the prices at which different firms sell, they often also do not know production costs. Consumer search models which take asymmetric information about production costs into account continue focusing on reservation price equilibria (RPE) and their properties. We argue that RPE assume specific out-ofequilibrium beliefs that are not consistent with the logic of the D1 re...

PURPOSE Radical radiotherapy for head and neck cancer (HNC) may deliver significant doses to brain structures. There is evidence that this may cause a decline in neurocognitive function (NCF). Radiation dose to the medial temporal lobes, and particularly to the hippocampi, seems to be critical in determining NCF outcomes. We evaluated the feasibility of two alternative intensity-modulated radio...

We present an agent-based computational economics (ACE) model of the wholesale "sh market in Marseille. Two of the stylized facts of that market are high loyalty of buyers to sellers, and persistent price dispersion, although it is every day the same population of sellers and buyers that meets in the same market hall. In our ACE model, sellers decide on quantities to supply, prices to ask, and ...
