We investigate optimal consumption, asset accumulation and portfolio decisions in a realistically calibrated life-cycle model with flexible labor supply. Our framework allows for wage rate uncertainly, variable labor supply, social security benefits and portfolio choice over safe bonds and risky...

We study how the use of judgement or “add-factors” in macroeconomic forecasting may disturb the set of equilibrium outcomes when agents learn using recursive methods. We isolate conditions under which new phenomena, which we call exuberance equilibria, can exist in standard macroeconomic...

The economics workings of the corporate income tax remain controversial. Harberger's seminal 1962 article viewed the tax as raising the cost of capital used to produce corporate goods. But corporate goods can be and generally are made by non-corporate firms, suggesting that the corporate tax...

Are smarter machines our children's friends? Or can they bring about a transfer from our relatively unskilled children to ourselves that leaves our children and, indeed, all our descendants - worse off? This, indeed, is the dire message of the model presented here in which smart machines...

This paper surveys major issues in the theory of tax incidence. These include the incidence of taxes in dynamic as well as static economies and open as well as closed economies. The survey does not represent a comprehensive review of the literature, rather it is offered to the reader as a...

We examine global dynamics under infinite-horizon learning in New Keynesian models where the interest-rate rule is subject to the zero lower bound. As in Evans, Guse and Honkapohja (2008), the intended steady state is locally but not globally stable. Unstable deflationary paths emerge after...

Determining how to value net government obligations is a long-standing and fundamental question in public finance. Its answer is critical to cost-benefit analysis, the assessment of fiscal sustainability, generational accounting, and other economic issues. This paper posits and simulates a...

In this paper, our aim is to develop an alternative approach to analyzing a macroeconomic model where markets do not clear. Earlier approaches have had difficulties in interpreting effective demand, a key concept in disequilibrium macroeconomics. We propose a new definition of effective demand...

This paper presents a new solution to the time-consistency problem that appears capable of enforcing ex ante policy in a variety of settings in which other enforcement mechanisms do not work. The solution involves formulating a law, institution, or agreement that specifies the optimal ex ante...
