In this contribution I address the type of emergency that threatens a state’s monopoly of violence, meaning that the state’s competence to provide citizens with elementary security is challenged. The question is, whether actions taken by the state to ward off these threats (should) fall within the ambit of the criminal law. A central problem is the indeterminacy that is inherent in the state of...

This paper studies the dynamics of fundamental research. We develop a simple model where researchers allocate their effort between improving existing fields and inventing new ones. A key assumption is that scientists derive utility from recognition from other scientists. We show that the economy can be either in a regime where new fields are constantly invented, and then converges to a steady s...

The Type Indeterminacy model is a theoretical framework that uses some elements of quantum formalism to model the constructive preference perspective suggested by Kahneman and Tversky. In a dynamic decision context, type indeterminacy induces a game with multiple selves associated with a state transition process. We define a Markov perfect equilibrium among the selves with individual identity (...

The state function of a quantum object is undetermined with respect to its phase. This indeterminacy does not matter if it is global, but what if the components of the state have unknown relative phases? Can useful computations be performed in spite of this local indeterminacy? We consider this question in relation to the problem of the rotation of a qubit and examine its broader implications f...

Martin and fieifer (1986) have claimed “that the most typical characterizations of intentionality . . . all fail to distinguish . . . mental states from . . . dispositional physical states.” The evidence they present in support of this thesis is examined in the light of the possibility that what it shows is that intentionality is the mark, not of the mental, but of the dispositional. Of the fiv...

It is well known that in dynamic general equilibrium economic models equilibrium may be indeterminate. Indeterminacy means that there is a continuum of equilibrium trajectories converging to the same steady state. Very often, the same mechanisms that are responsible for indeterminacy, like increasing returns to scale or market imperfections, lead to existence of multiple steady states, and deve...

This paper distinguishes two kinds of endogenous business cycle models: EBC1 models, which display dynamic indeterminacy, and EBC2 models, which display steady-state indeterminacy. Both strands of the literature have their origins in the sunspot literature that developed at the University of Pennsylvania in the 1980s. I argue that EBC1 models are part of the evolution of modern macroeconomics t...

We study the joint dynamics of labor reallocation and environmental change when workers have rational expectations and incur migration costs. We emphasize the relation between parameter values and the area of state space in which indeterminacy of equilibria can occur. Unlike the one-dimensional model in which the wage differential adjusts instantaneously, here the measure of the region of indet...

Based on fuzzy language field and fuzzy language value structure, a new knowledge representation frame is presented. A generalized cell automation and the corresponding generalized induction logic causal model are also proposed, which can synthetically process random and fuzzy indeterminacy. Thus, a new indeterminacy causal induction auto-reasoning mechanism is presented on the basis of fuzzy s...
