Real option valuation with neural networks

We propose to use neural networks to value options when analytical solutions do not exist. The basic idea of this approach is to approximate the value function of a dynamic program by a neural net, where the selection of the network weights is done via simulated annealing. The main benefits of this method as compared to traditional approximation techniques are that there are no…

Evaluation of Aggressive Competitive Pricing Strategies

The main contribution of this paper is a method that allows one to study the effects of different degrees of competition. We find that optimal prices and profits are more sensitive to cooperative than to aggressive behavior on the part of competitors. With more aggressive policies, the average pricing level decreases and the average difference between high and low prices increases.…

On the asymptotic convergence to mixed equilibria in 2×2 asymmetric games

We analyse the stability properties of mixed equilibria in 2×2 asymmetric games under evolutionary dynamics. With the standard replicator dynamics these equilibria are stable but not asymptotically stable. We modified the replicator dynamics by introducing players of two types: myopies — like in the standard replicator dynamics — and best
responders. The behaviour of the latter…

The impact of income inequality on product diversity and long-run economic growth in a model with hierarchical demand

The paper presents an empirical analysis of a model of endogenous growth and innovation with unequal incomes and hierarchical consumer demand. The theoretical model predicts a positive impact of income inequality on product diversity. The impact of inequality on per-capita growth may be positive or negative depending upon the assumptions about productivity growth, where the standard…

Why are the unemployed so unhappy? Evidence from panel data

This paper tests for the importance of non-pecuniary costs of unemployment using a longitudinal data-set on life-satisfaction of working-age men in Germany. We show that unemployment has a large detrimental effect on satisfaction after individual specific fixed effects are controlled for. The non-pecuniary effect is much larger than the effect that stems from the associated loss of…

How young workers get their training: A survey of Germany versus the United States

The recent economic literature on the incidence of various forms of post-secondary on-the-job and off-the-job training in Germany and the United States, as well as on the effects of training on wages, inequality, and labor mobility is surveyed. Young workers in Germany receive substantially more company-based (apprenticeship) training than United States workers. In the United States…

Embeddedness, power, control and innovation in the telecommunications sector

In the present paper, relationships between embeddedness, power, control and innovation are examined in the context ofthe telecommunications sector. It is contended that in a tightly embedded, technology-intensive sector, technological and economic control are closeb intertwined. Consequently, the ability to appropriate economic rents is large& based on technological control. In…

Adaptive methods in macroeconomic forecasting

Adaptive methods are used to forecast three main Austrian economic indicators. We use a weighted recursive model as well as a neural network approach both with and without adaptive characteristics and compare our results to the forecasts of two Austrian research institutes. It appears that even models which use very limited information can outperform the two Institutes’ forcasts of…

The choice between emission taxes and output taxes under imperfect monitoring

We consider a regulator's choice between environmentally motivated emissions taxes and output taxes. We investigate how the optimal instrument depends on the monitoring cost function, the firm's technology, and on social preferences regarding output and environmental quality. Pure emissions taxes are usually not optimal with monitoring costs. Pure output taxes are optimal…
