Produce or speculate? : asset bubbles, occupational choice and efficiency
Cahuc, Pierre; Challe, Edouard - 2009
We study the macroeconomic effects of rational asset bubbles in an overlapping-generations economy where asset trading … are large, the private gains associated with trading asset bubbles may lead too many workers to become speculators …, thereby causing rational bubbles to lose their efficiency properties. Moreover, if speculation can be carried out by skilled …

Inequality in an OLG economy with heterogeneous cohorts and pension systems
Tyrowicz, Joanna; Makarski, Krzysztof; Bielecki, Marcin - 2018
We analyze the consumption and wealth inequality in an OLG model with mandatory pension systems. Our framework features within cohort heterogeneity of endowments and heterogeneity of preferences. We allow for population aging and gradual decline in TFP growth. We show four main results. First,...

Evaluating welfare and economic effects of raised fertility
Makarski, Krzysztof; Tyrowicz, Joanna; Malec, Magda - 2019
Many countries consider rising fertility through pro-family policies as a solution to the fiscal pressure stemming from longevity. However, an increased number of births implies immediate private costs and only delayed public benefits of younger and larger population. We propose using an...

Unions, increasing returns and endogenous fluctuations
Modesto, Leonor; Lloyd-Braga, Teresa; Coimbra, Rui - 2000
We analyse the implications of unions (efficient bargaining) for multiplicity of stationary states and welfare, local indeterminacy, bifurcations and endogenous fluctuations (deterministic and stochastic). We use an overlapping generations model with external increasing returns to scale, where...

Secular satiation
Saint-Paul, Gilles - 2017

Labor income share dynamics with variable elasticity of substitution
Paul, Saumik - 2019
The accumulation principle suggests that complementarity between capital and labor forces the labor income share to rise in the presence of capital accumulation. The CES model estimates using data from 20 Japanese industries between 1970 and 2012 explain the same outcome but with substitutable...

A decline in labor's share with capital accumulation and complementary factor inputs : an application of the Morishima elasticity of substitution
Paul, Saumik - 2019
The role of capital accumulation as a driver of the labor income share requires capital and labor to be substitutes, which appears paradoxical in a world predominantly characterized by complementarity between capital and labor. This paper argues that the composition of skills in the labor force...

Interest rate hysteresis in macroeconomic investment under uncertainty
Belke, Ansgar; Göcke, Matthias - 2019
The interest rate is generally considered as an important driver of macroeconomic investment. As an innovation, this paper derives the exact shape of the "hysteretic" impact of changes in the interest rate on macroeconomic investment under the scenarios of both certainty and uncertainty. We...

Short-time work and precautionary savings
Dengler, Thomas; Gehrke, Britta - 2021
In the Covid-19 crisis, most OECD countries use short-time work schemes (subsidized working time reductions) to preserve employment relationships. This paper studies whether short-time work can save jobs through stabilizing aggregate demand in recessions. We build a New Keynesian model with...

Business cycle effects of credit and technology shocks in a DSGE model with firm defaults
Pesaran, M. Hashem; Xu, TengTeng - 2011
This paper proposes a theoretical framework to analyze the impacts of credit and technology shocks on business cycle dynamics, where firms rely on banks and households for capital financing. Firms are identical ex ante but differ ex post due to different realizations of firm specific technology...
