This paper deals with the German apprenticeship training system. We first set the scene by describing the operation of the system, including the statistical picture in terms of supply and demand and costs; the relationship between the vocational training and the educational systems; the complex...

Verschiedene Verbindungen zwischen lokalen Kapitaleinheiten können Komplementaritäten in den Standortentscheidungen begründen: Skalenerträge und Spillovereffekte, Input- Output-Beziehungen bei Transportkosten und EinkommenskreislaufefTekte. In einem stilisierten Modell wird ihr simultaner...

In this paper we examine the asymptotic properties of the estimator of the long-run coefficient (LRC) in a dynamic regression model with integrated regressors and serially correlated errors. We show that the OLS estimators of the regression coefficients are inconsistent but the OLS-based...

Host country governments often grant investment incentives to foreign firms locating in their territories. We show that such preferential treatment of foreign firms can facilitate transfer of foreign technology, induce entry by the local firm, and increase host country welfare. However, this...

This paper examines the optimal entry policy towards oligopoly in a globalized world. In an open economy free entry is socially suboptimal, but corrective tax policy to curb entry proves insufficient unless internationally harmonized. Thus, while conferring the gains from trade, globalization...

This paper studies the possibility of strategy-proof rules yielding satisfactory solutions to matching problems. Alcalde and Barberá (1994) show that effcient and individually rational matching rules are manipulable in the one-to-one matching model. We pursue the possibility of strategy-proof...

This paper provides a review of some recent theoretical results for time series models with GARCH errors, and is directed towards practitioners. Starting with the simple ARCH model and proceeding to the GARCH model, some results for stationary and nonstationary ARMA-GARCH are summarized. Various...
