We characterize a class of dynamic stochastic games that we call separable dynamic games with noisy transitions and establish that these widely used models are protocol invariant provided that periods are sufficiently short. Protocol invariance means that the set of Markov perfect equilibria is...

In Tversky's (1969) model of a lexicographic semiorder, preference is generated by the sequential application of numerical criteria, by declaring an alternative x better than an alternative y if the first criterion that distinguishes between x and y ranks x higher than y by an amount exceeding a...

We generalize the standard revealed preference exercise in economics, and prove a sufficient condition under which the revealed preference formulation of an economic theory has universal implications and when these implications can be recursively enumerated. We apply our theorem to two theories...

This paper offers a resolution to an extensively studied question in theoretical economics: which measure spaces are suitable for modeling many economic agents? We propose the condition of “nowhere equivalence” to characterize those measure spaces that can be effectively used to model the...

A Hobbesian society is modeled to study how the market emerges from violence. From a Cournot military contest for wealth, primitive markets emerge when Rousseau's Garden of Eden or an arms race is the equilibrium rather than war. Politically-dominated (e.g., socialist) or Smithian markets with a...

In today’s technology-driven world-economy, banking-services have been modernized where customers compete for comparative time-saving-options. Bangladesh, a developing country, is no exception. Besides traditional banking, Agent-banking, bKash, Western-Union etc. serve new-way...

We examine the connection between discrete-time models of financial markets and the celebrated Black--Scholes--Merton (BSM) continuous-time model in which ''markets are complete." Suppose that (a) the probability law of a sequence of discrete-time models converges to the law of the BSM model and...

We analyze the structure of a society driven by power relations. Our model has an exogenous power relation over the set of coalitions of agents. Agents determine the social order by forming coalitions. The power relations determine the ranking of agents in society for any social order. We study...

Innerhalb der ersten Förderphase ist von den Forschungsdatenzentren der Statistischen Ämter des Bundes und der Länder eine Dateninfrastruktur geschaffen worden, die umfangreiche wissenschaftliche Analysen amtlicher Mikrodaten aus allen Bereichen zulässt. In diesem Aufsatz wird insbesondere...
