Sample-Path Stability of Non-Stationary Dynamic Economic Systems (Revised Version)

The goal of this paper is to introduce and illustrate a new approach to the stability analysis of sample-paths of nonlinear stochastic economic models with non-stationary components. We place our study within the mathematical theory of random dynamical systems and apply the concept of a random fixed point which is tailor-made for the study of the long-term behavior of sample-paths in...

A Utopia? Government without Territorial Monopoly

"We normally take it for granted: a government or state has its corresponding territory. This paper shows that government need not have a territorial monopoly. The paper advances a practical, constitutional proposal, based on the notion that there are meaningful government units, whose major characteristic is not the territorial extension but its function. The constitution...

Empirische Analyse des Zeitpunktes schweizerischer Direktinvestitionen in Osteuropa

Die Studie untersucht die Eigenschaften der Unternehmen, die als Erste in einen sich neu oeffnenden Markt investieren. Fuer den ersten Investor bestehen gewisse Vorteile (first-mover-advantages), die einen moeglichst fruehen Eintritt in den Markt nahe legen. Andererseits fuehrt die politische und wirtschaftliche Unsicherheit in Osteuropa zu einem Anreiz, die Investitionsentscheidung...

Tracking Error and Tactical Asset Allocation

The relationship between statistical measures of tracking error and asset allocation restrictions expressed as admissible weight ranges is discussed. Tracking errors are typically calculated as annualized second moments of return differentials between a portfolio and a benchmark. In practice, however, constraints on tactical deviations from benchmark weights are often imposed on the...

Consumption and Nutrition: Age - Intake Profiles for Czechoslovakia

This paper provides non-parametric estimates of the relation between nutrient intake and age for Czechoslovak individuals, as a function of both the characteristics of the individual and of their household, on the basis of household purchases. Results show no significant difference between the age-energy intake profiles of men and women. The decomposition of this intake between...

Measurement and Control of Business Processes

It is widely accepted that any well-designed organizational process includes a control mechanism through which management decides which aspects of the performance of the process are to be measured and how these measurements are to be used to change the level of resources utilized in the process. Little is known, however, about the best ways to design such a control mechanism for...

Intelligent Organizations: An Integrative Framework

The purpose of this paper is to demonstrate how cybernetic theories open new paths towards organizational intelligence. This is illustrated by means of three theoretical models from organizational cybernetics. These models are integrated into a framework for a virtuous design, (self-)control and (self-)transformation of organizations. It is proposed that changes in activities,...

Fairness, Incentives and Contractual Incompleteness

We show that concerns for fairness may have dramatic consequences for the optimal provision of incentives in a moral hazard context. Incentive contracts that are optimal when there are only selfish actors become inferior when some agents are concerned about fairness. Conversely, contracts that are doomed to fail when there are only selfish actors provide powerful incentives and...

Energy Tax Reform with Exemptions for the Energy-Intensive Export Sector (Revised Version wp 29)

The present paper applies a theoretical two-sector three-factor model to analyze a variety of energy tax reforms with the common feature of at least partly exempting the energy-intensive export sector from the tax. As a result, all scenarios with exemptions reduce energy less than the non-discriminating textbook version of the energy tax. Moreover, in the two scenarios that exemplify...

Contracted workdays and absence

We present results of a negative binomial model on the determinants of the number of days of absence in a given year for a sample of 2049 workers drawn from three factories. We find evidence of the terms of the remuneration contract being important and we offer an interpretation of the differential effect of the company sickpay scheme on the behaviour of workers contracted to work...

Markov chain Monte Carlo analysis of correlated count data

This article is concerned with the analysis of correlated count data. A class of models is proposed in which the correlation among the counts is represented by correlated latent effects. Special cases of the model are discussed and a tuned and efficient Markov chain Monte Carlo algorithm is developed to estimate the model under both multivariate normal and multivariate-t assumptions...

Investment and market dominance

We analyze a model of oligopolistic competition with ongoing investment. Special cases include incremental investment, patent races, learning by doing, and network externalities. We investigate circumstances under which a firm with low costs or high quality will extend its initial lead through investments. To this end, we derive a new comparative statics result for general games with...

Skill supply, supervision requirements and unemployment of low-skilled labor

This paper presents a model with flexible wages in which unemployment of low-skilled labor is possible in equilibrium, whereas high-skilled workers are fully employed. Thus, the model can explain why even in countries with flexible labor markets and full employment of skilled labor an employment problem exists at the bottom of the skill spectrum. The model is used to evaluate the...
