This paper studies the effects of heterogeneity in planning propensity on wealth inequality and asset prices. I consider an economy populated by attentive and inattentive agents. Attentive agents plan their consumption period by period, while inattentive agents plan every other period....

Time series subject to parameter shifts of random magnitude and timing are commonly modeled with a change-point approach using Chib's (1998) algorithm to draw the break dates. We outline some advantages of an alternative approach in which breaks come through mixture distributions in state...

How can we explain the observed behavior of aggregate inflation in response to e.g. monetary policy changes? Mankiw and Reis (2002) have proposed sticky information as an alternative to Calvo sticky prices in order to model the conventional view that i) inflation reacts with delay and gradually...

This paper takes a fresh look at two issues in the aid effectiveness debate. We begin by providing theoretical foundations for the various claims made with regard to the effectiveness of aid in stimulating long-run productivity. When foreign aid is modelled as an exogenous transfer of income or...

The paper investigates strategic campaigning in a model of redistributive politics in a society with many groups and two parties. Campaigns are informative, and parties can target campaigns to different groups. Voters are uncertain about whether parties favor special groups. The parties will...

This paper examines the welfare implications of non-discriminatory tariff reforms by a subset of countries, which we term a non-preferential trading club. We show that there exist coordinated tariff reforms, accompanied by appropriate income transfers between these countries, that unambiguously...

In the modern welfare state a substantial part of an individual's tax bill is transferred back to the same individual taxpayer in the form of social transfers. This provides a rationale for financing part of social insurance through mandatory savings accounts. We analyze the behavioral and...

Questions over the role of the IMF in the economic development and adjustment in developing countries have been the topic of intensive research and debate in recent years. Although most studies find that participation in an IMF program helps facilitate balance of payments adjustment, research in...

We study the effects of fiscal policy rules on the determinacy of rational expectations equilibrium in a perfectly competitive monetary model with constant returns. Government spending implies a distortion of the monetary steady state due to the implied taxation. We show that policy rules that...

Fiscal policy is examined in a model of an open economy which is characterised by unemployment caused by efficiency wages. It is shown that the conventional conclusion, according to which mobile capital is untaxed in the presence of wage taxation, is not generally valid. A positive capital tax...
