In a small open economy fluctuations in the real exchange rate can affect plant turnover, and thus aggregate productivity, by altering the makeup of plants that populate the market. An appreciation of the local currency increases the level of competition in the domestic market as import...

This paper presents a model comparing the optimal degree of asset class diversification abroad by a central bank and a sovereign wealth fund. We show that if the central bank manages its foreign asset holdings in order to meet balance of payments needs, particularly in reducing the probability...

In a duopoly industry with environmentally differentiated products, we examine the effects of introducing a mandatory environmental quality standard on firms' environmental quality choices, profits, and the average environmental quality offered by the industry. We show that at low standard...

Die anhaltend hohe Arbeitslosigkeit hat verstärkt zu Diskussionen geführt, ob das Steuer-Transfer-System hierfür mitverantwortlich sei. Dabei wurde insbesondere auf die sehr hohe implizite Grenzbelastung im untersten Einkommensbereich hingewiesen. Als Alternativen wurden eine negative...

We propose inference procedures for partially identified population features for which the population identification region can be written as a transformation of the Aumann expectation of a properly defined set valued random variable (SVRV). An SVRV is a mapping that associates a set (rather...

A correlated equilibrium for a normal form game is a mediator whose recommendations the players find optimal to follow obediently. A (direct) correlation device or a mediator however may face the multiple equilibrium problem as the obedient strategy profile may be dominated by some other Nash...

Foreign aid donors and recipient governments often have conflicting objectives. Foreign donors may attempt to influence the policies of recipient governments by offering aid or threatening to suspend aid to sovereign states. This paper considers the credibility of such inducements and the...

We propose an equilibrium concept, the Robust Nash equilibrium (RNE), that combines the best-reply rationality and the first mover invariance condition. The single-stage 2x2 symmetric information game G is transformed into sequential two-stage games with two sub-trees: STA has the row player...

This study presents a more general collusive mechanism that is sustainable in an oligopolistic repeated game. In this setup, firms can obtain average payoffs beyond the cooperative profits while at the same time improve consumer welfare through a lower market price offer. In particular, we...

A comparative-static model describes the decline of manufacturing in the face of rising overseas employment through a mechanism other than the Dutch Disease. Instead it is competition for skilled labour and the relative ease in producing skills that affect the size of the manufacturing sector,...
