An increasing body of evidence suggests that the behavior of the economy has changed in many fundamental ways over the last decades. In particular, greater financial deregulation, larger wealth accumulation, and better policies might have helped lower uncertainty about future income and lengthen...

This paper examines whether there is a case for temporary but persistent fiscal surpluses in economies heavily endowed with nonrenewable resources. It finds that there generally is a case. Fiscal surpluses permit replacing nonfinancial wealth with financial assets, the return on which increases...

This paper utilizes an open-economy New Keynesian overlapping generations model, the Global Integrated Monetary and Fiscal Model (GIMF), to assess the macroeconomic effects of external shocks and the impact of various monetary and fiscal policy responses. The simulations assess the effect of...

As of 2015, U.S. log output per capita was 12 percent below what its pre-2008 linear trend would predict. To understand why, I develop and estimate a model of the US with demographics, real and monetary shocks, and the occasionally binding ZLB on nominal rates. Demographic changes generate...

This paper analyzes the dynamic interactions between the precision of information, technological development, and welfare within an overlapping generations model. More precise information about idiosyncratic production shocks has ambiguous effects on technological progress and welfare, which...

This paper examines the link between capital stock and unemployment persistence. An overlapping-generations model with endogenous labor supply and imperfect competition is presented. It is used to interpret the unusual persistence of unemployment in Trinidad and Tobago during the last twenty...

I study the implications of productivity shocks in a model where agents observe the aggregate level of productivity but not its permanent and transitory components separately. The model''s predictions under learning differ substantially from those under full information and are in line with...

Migrants, being relatively low earners, are net beneficiaries of the welfare state. However, this paper uses a dynamic model to show that because of migrants’ positive influence on the pension system, which is an important pillar of any welfare state, migration could be beneficial to all...

The paper explicitly models the dynamic strategic aspects of the interaction between the migrant and the remittance-receiving relative(s), with the migrant behaving as a Stackelberg leader. It is also different from other formalizations of remittance behavior in its treatment of the two...
