We provide an explanation why centralisation of political decision makingresults in overspending in some policy domains, whereas too low spending persists in others.We study a model in which delegates from jurisdictions bargain over local public goods provision.If all of the costs of public...

This paper provides an empirical description of the relationshipbetween the trading system operated by a stockexchange and the transaction costs faced by heterogeneous investors who use the exchange. Therecent introduction ofSETS in the London Stock Exchange provides an excellent opportunity...

This paper offers an explanation for why policy makers stick to inefficient policy decisions. I argue that repealing a policy is a bad signal to voters about the policy maker's competence if voters do not have complete knowledge about the effects of implemented policies. I derive the optimal...

Uncertainty about the future preferences of the government may induce policy makers to run excessive budget deficits. As a solution to this problem, economists have proposed to impose a binding debt rule. In this paper we argue that a binding debt rule does not eliminate the distortions due to...

In this paper we test for (Generalized) AutoRegressive Conditional Heteroskedasticity [(G)ARCH] in daily data on 22 exchange rates and 13 stock market indices using the standard Lagrange Multiplier [LM] test for GARCH and a LM test that is resistant to patches of additive outliers. The data span...

A key application of long memory time series models concerns inflation. Long memory implies that shocks have a long-lasting effect. It may however be that empirical evidence for long memory is caused by neglecting one or more level shifts. Since such level shifts are not unlikely for inflation,...

If distortions in the labour market lead to inefficiently highunemployment, and policy makers cannot enter into a binding policy commitment before nominal wages are set, excessive inflation may result due to a credibility problem. This is the famous Kydland&Prescott - Barro&Gordon inflationary...

After decades of government growth, Western countries have witnessed major policy reversals. Prominent examples include the far-reaching policy reversals implemented by Thatcher, Reagan, and Douglas. This paper offers an explanation for these policy reversals. Our key argument rests on the...

This paper develops a model in which workers are heterogeneous in their intrinsic motivation to work at a firm. We characterise optimal incentive schemes and examine how the firm can attract and select highly motivated workers to fill a vacancy when workers’ motivation is private information....

It is conceivable that the whether to buy and how much tobuy decisions in the purchasing process of households areinfluenced by the inventory process. In this paper we thereforeput forward a model for consumption, where we rely on establishedeconomic theory. We incorporate this model in a model...
