In this paper, the course-related training of elderly workers in Switzerland isanalysed with data from the Swiss Labour Force Survey. Elderly individuals invest substantialamounts in their human capital via course-related training...

Die Frage nach der richtigen Ausgestaltung marktwirtschaftlichen Wettbewerbsist eine, die Politiker, Wirtschaftswissenschaftler und nicht zuletzt Unternehmerund ihre Interessenverbände seit langer Zeit bewegt. Trotz der langen und intensiven Diskussionen ist es dennoch bis dato nicht gelungen,...

In this paper, we experimentally test the Modigliani-Miller theorem. Applying ageneral equilibrium approach and not allowing for arbitrage among ¯rms with differ-ent capital structure, we are able to address a question fundamental to the valuationof firms: does capital structure affect the...

Die Frage nach der Kausalität fällt in die Methodologie. Methodologie ist in denWirtschaftswissenschaften ein Bereich, der sowohl bei Ökonomen als auch bei Philosophenkaum Beachtung findet. ....

We derive representations for the stock price drift and volatility in theequilibrium of agents with arbitrary, heterogeneous utility functionsand with the aggregate dividend following an arbitrary Markov diffusion.We introduce a new, intrinsic characteristic of the aggregate dividendprocess that...

We consider a simple continuous-time economy, populated by a largenumber of agents, more risk averse than the log agent, with heterogeneousrisk aversion densely covering an interval. Even though thedividend is a geometric Brownian motion, the equilibrium investmentopportunity set is stochastic...

In all the existing literature on survival in heterogeneous economies,the rate at which an agent vanishes in the long run relative to anotheragent can be characterized by the difference of the so-called survivalindices, where each survival index only depends on the preferencesof the...

We perform a detailed asymptotic analysis of the equilibrium behavior of the assetprices, wealth size and portfolio weights in complete markets equilibria, with long-livedfunds. In equilibrium, the fund with the (closest to) log preference will dominate theother funds in size, in the long-run,...

This article shows that, as long as agents are required to maintain positivewealth, the presence of portfolio constraints may give rise to asset pricingbubbles in equilibrium even if there are unconstrained agents in the economywho can benefit from the induced arbitrage opportunity. Furthermore,...

We build a model of the financial sector to explain why adverse asset shocks in good economic timeslead to a sudden drying up of liquidity. Financial firms raise short-term debt in order to finance assetpurchases. When asset fundamentals worsen, debt induces firms to risk-shift; this limits...
