We propose a model of economic growth in which technological progress is modelled as an expanding random network of ideas. New ideas are created by combining successful old ideas. Old ideas are chosen according to their visibility as ideas, success as generators of innovations and age but the...

The main contribution of this paper is to place smooth infinite economies in the setting of the equilibrium manifold and the natural projection map à la Balasko. We show that smooth infinite economies have an equilibrium set that has the structure of a Banach manifold and that the natural...

We study global properties of the equilibrium set of economies with a continuous consumption space. This framework is important in intertemporal allocation problems (continuous or infinite time), financial markets with uncertainty (continuous states of nature) and commodity differentiation. We...

We present a general equilibrium model of the new neoclassical synthesis that has the same level of generality as the Arrow-Debreu model. This involves a stochastic multi-period economy with a monetary sector and sticky commodity prices. We formulate the notion of a sticky price equilibrium...

In a simple single commodity certainty setting with changing tastes, a consumer's consumption plan can be obtained using naive or sophisticated choice. Although in general these solutions diverge, they agree in the special case where the changing tastes are represented by discounted logarithmic...

The present paper examines impacts of foreign exchange rates against the Sudanese currency on savings. The increasing rates of foreign currencies in the domestic Sudanese Black markets have simultaneously resulted in the continuous depreciated Sudanese currency values over the past year...

In this paper, we introduce our GDSGE framework and MATLAB toolbox for solving dynamic stochastic general equilibrium models with a novel global solution method. The framework encompasses many well-known incomplete markets models with highly nonlinear dynamics such as models on financial crises,...

We elicit individual measures of patience by applying the new Preference for Earlier versus Later Income (PELI) scale for more than 50,000 individuals from 65 countries who took the Gallup End of Year Survey. This simple to apply measure is highly correlated with alternative measures that are...

We construct an index theorem for smooth infinite economies that shows that generically the number of equilibria is odd. As a corollary, this gives a new proof of existence and gives conditions that guarantee global uniqueness of equilibria. -- Uniqueness ; determinacy ; equilibria ; infinite...

This dissertation was written by Johannes Pfeiffer while he was working with the ifo Institute for Economic Research. It was completed in November 2016 and accepted as a doctoral thesis by the department of economics of the University Regensburg in December 2016. The thesis studies unintended...
