In a labour market characterised by linear turnover costs in employment, the hold-up issue may arise and firms may invest inefficiently. This paper introduces hiring and firing costs in a dynamic general equilibrium, and analyses the effects of two different contractual arrangements, employment...

Jenovian trade theory was the original species of neoclassical trade theory. It treats countries as trading bodies with utility functions for consumption and disutility functions for labour. Edgeworth derived offer curves from tastes and technology; Jevon's model resembles the modern specific...

Models with externalities have become increasingly popular for studying both long-term growth and business cycle fluctuations. Externalities can lead to indeterminacy, allowing self-fulfilling expectations to determine the equilibrium. This paper argues that the importance of indeterminacy might...

Kohlberg and Mertens argued that a solution concept to a game should be invariant under the addition of deletion of an equivalent strategy and not require the use of weakly dominated strategies. In this paper we study which of these requirements are satisfied by Kalai and Samet's concepts of...

This paper analyses competition between firms who sell multiple products in the presence of negative externalities. The model involves two networks who each may offer several service classes. Service classes are generated by forming sub-networks differentiated by their congestion levels. The...

In examining China's exchange rate policy in the reforming years, the paper finds empirical evidence of its long-run inflationary consequences, but the effects appear to be not sizable. In the short-run, while changes in the devaluation rate are positively correlated with the increase in the...

Intergovernmental grants are not available to all federations. In this paper, optimal federal tax policies in a multileveled government framework are studied, when the federal authority has no access to intergovernmental grants, and the state governments implement the residence principle. A...

Following Blinder's (1997) suggestion, we examine the implications for the optimal interest rate rule following the relaxation of the assumption that the policymaker's loss function is quadratic. We investigate deviations from quadratics for both symmetric and asymmetric preferences for a single...

This chapter reviews recent developments in the study of individual employment contracts. It discusses three reasons for an employer and an employee to have a contract: (i) to allocate risk in a way different from a spot market; (2) to enhance the efficiency of investment decisions by protecting...

Despite the fact that it is not correct to speak of Bartlett corrections in the case of non-stationary time series, this paper shows that a Bartlett-type correction to the likelihood ratio test for a unit root can be an effective tool in order to control size distortions. Using well-known...
