The article examines strategies for making financial investments by using a decomposition of the non-central tracking error variance to indicate how actively assets are managed. This method examines how much risk the asset manager takes in investments by analyzing positive and negative returns. Two mathematical models are presented to analyze the active management of investments. The…

Optimal insurance contracts without the non-negativity constraint on indemnities: revisited

In the literature on optimal indemnity schedules, indemnities are usually restricted to be non-negative. Keeler [1974] and Gollier [1987] show that this constraint might well bind: insured could get higher expected utility if insurance contracts would allow payments from the insured to the insurer at some losses. This paper extends Collier’s findings by allowing for negative…

Income distribution and demand-induced innovation

We introduce non-homothetic preferences into an innovation-based growth model and study how income and wealth inequality affect economic growth. We identify a (positive) price effect -- where increasing inequality allows innovators to charge higher prices and (negative) market-size effects -- with higher inequality implying smaller markets for new goods and/or a slower transition of…

Evaluations: Hidden Costs, Questionable Benefits, and Superior Alternatives

Research evaluation is praised as the symbol of modern quality management. We claim firstly, performance evaluations in research have higher costs than normally assumed, because the evaluated persons and institutions systematically change their behavior andndevelop counter strategies. Moreover, intrinsic work motivation is crowded out and undesired lock-in effects take place.…

Bias Reducing Estimation of Treatment Effects in the Presence of Partially Mismeasured Data

Labor market policy evaluation studies often rely on a merged database from different administrative entities, where part of the information might be archived with varying quality in different sources. Suppose that one observes inter alia a variable of dubious quality for the entire population and the same variable for a subgroup, say the treated, with good quality from an extra…

Financial performance of privately held family firms

The present text examines how the organizational input variable "family" and the financial output variable "return" are interrelated. This question is crucial since there are serious doubts brought forward by Schulze et al. (2003) whether family firms really exhibit the ideal precondition of low agency costs as hypothesized by Fama and Jensen (1983a and 1983b).…

The Effect of Market Regimes on Style Allocation

We analyse time-varying risk premia and the implications for portfolio choice. Using Markov Chain Monte Carlo (MCMC) methods, we estimate a multivariate regime-switching model for the Carhart (1997) four factor model. We find two clearly separable Regimes with different mean returns, volatilities and correlations. In the High-Variance Regime, only value stocks deliver a good…

Making prospect theory fit for finance

The prospect theory of Kahneman and Tversky (in Econometrica 47(2), 263–291, 1979) and the cumulative prospect theory of Tversky and Kahneman (in J. Risk uncertainty 5, 297–323, 1992) are descriptive models for decision making that summarize several violations of the expected utility theory. This paper gives a survey of applications of prospect theory to the portfolio choice problem…

Learning in and about Games

We study finitely repeated 2 / 2 normal form games, where playersnhave incomplete information about their opponents’ payoffs. In a laboratory experiment we investigate whether players (a) learn the game they are playing, (b) learn to predict the behavior of their opponent, and (c)nlearn to play according to a Nash equilibrium of the repeated game. Ournresults show that the success in…

Entrepreneurship as a non-profit-seeking activity

It is typically assumed that people engage in entrepreneurship because there are profits to be made. In contrast to this view, this paper argues that entrepreneurship is more adequately characterized as a non-profit-seeking activity. Evidence from a broad range of authors and academic fields is discussed showing that entrepreneurship does quite generally not pay in monetary terms.…

The Simple Analytics of U.S. Antidumping Orders: Bureaucratic Discretion, Anti-Importer Bias, and The Byrd Amendment

Using a standard linear version of the Bertrand duopoly model of competition, I analyse the effect on firm pricing behaviour of three prominent features of the U.S. antidumping system. I identify the circumstances under which these features eliminate dumping entirely as well as their effects on the profitability of the import-competing and foreign firms. The Byrd Amendment, which has…

System Dynamics and the Evolution of the Systems Movement

The purpose of this contribution is to give an overview of the role of System Dynamics (SD) in the context of the evolution of the systems movement. This is necessary because SD is often erroneously taken as the systems approach as such, not as part of it. It is also requisite to show that the processes of evolution of both SD in particular and the Systems Movement as a whole are…
