This paper revisits the no-attachment assumption in job search models with random productivity fluctuations and Nash-bargaining. Both workers and firms value the option to remain in attachment: firms profit from a reduced hiring cost, while workers gain from a higher reservation wage when...

This paper considers job separations in a search model with labour market matching and moral hazard. Both workers and firms value productive matches and take actions to increase match stability: firms offer a share of match surplus to provide workers with correct incentives and workers take...

As the positive impact of trust on business success is widely undisputed, the question of how to measure trust naturally arises. Both expectations of trustworthy behavior and possible gains and losses from a trusting relationship influence the level of trust between two parties or individuals....

Using the POLITY IV and Freedom House indices, Rowley and Smith (2009) found that countries with Muslim majorities enjoy less freedom and are less democratic than countries in which Muslims are a minority. Because the POLITY IV and Freedom House indices have been criticized on several grounds, I...

In the continuous time-Merton-model the instantaneous stock proportions are inversely proportional to the investor’s local relative risk aversion γ. This paper analyses the conditions under which a HARA-investor can use this 1/γ-rule to approximate her optimal portfolio in a finite time...

We document that S&P 500 futures finish in the proximity of the closest strike price more often on days when serial options on S&P 500 futures expire than on other days. The effect is driven by the interplay of market makers' rebalancing of delta hedges due to the time-decay of the hedges as...

The optimal reporting frequency is an important issue in accounting. In many production settings, substitution effects across periods occur. This paper shows that the optimal reporting frequency depends on the strength of the substitution effect and on the information content of performance...

We examine the use of second-order stochastic dominance as both a way to measure performance and also as a technique for constructing portfolios. Using in-sample data, we construct portfolios such that their second-order stochastic dominance over a typical pension fund benchmark is most...

We empirically analyze Taylor-type equations for short-term interest rates in the United Kingdom using quarterly data from 1970Q1 to 2006Q2. Starting from strong evidence against a simple linear Taylor rule, we model nonlinearities using logistic smooth transition regression (LSTR) models. The...

This paper examines whether government ideology has influenced the allocation of public expenditures in OECD countries. I analyze two datasets that report different expenditure categories and cover the time periods 1970-1997 and 1990-2006, respectively. The results suggest that government...
