We propose a quantum-like description of markets and economics. The approach has roots in the recently developed quantum game theory. Quantum Zeno paradoxes and noncomutative quantum mecanics are also discussed.

This paper builds on Kočenda (2001) and extends it in two ways. First, two new intervals of the proximity parameter ε (over which the correlation integral is calculated) are specified. For these ε- ranges new critical values for various lengths of the data sets are introduced and through...

This cumulative working paper contains the unified joint research completed so far on monetary aggregation under risk, including the extension of index number theory needed to incorporate adjustments for risk into the rate structure, experiments on tracking ability of the unadjusted index, and...

This paper presents theoretical models and their empirical results for the return and variance dynamics of German stocks. A factor structure is used in order to allow for a parsimonious modeling of the first two moments of returns. Dynamic factor models with GARCH dynamics (GARCH(1,1)-M,...

Uncovered interest rate parity (UIP) is one of three key theoretical relations used in analytical work in both international finance and international monetary economics. The problem, however, is that UIP does not seem to hold up well empirically. In this paper, we argue that the failures of UIP...

This paper analyzes the dynamics and determinants of the relative benefits of geographical and industry diversification over the last 30 years. First, we develop a new structural regime-switching volatility spillover model to decompose total risk into a systematic and a country (industry)...

Researchers who have examined markets populated by "robot traders" have claimed that the high level of allocative efficiency observed in experimental markets is driven largely by the "intelligence" implicit in the rules of the market. Furthermore, they view the ability of agents (artificial or...

Recent empirical results about the US term structure are difficult to reconcile with the classical hypothesis of rational expectations even if time-varying but stationary term premia are allowed for. A hypothesis of rational learning about the conditional variance of the log pricing kernel is...

Modern aggregation theory and index number theory were introduced into monetary economics by Barnett (1980). The widely used Divisia monetary aggregates were based upon that paper. A key result upon which the rest of the theory depended was Barnett’s derivation of the user-cost price of...

We measure the United States capital stock of money implied by the Divisia monetary aggregate service flow, in a manner consistent with the present-value model of economic capital stock. We permit non-martingale expectations and time varying discount rates. Based on Barnett’s (1991) definition...
