Colombia is one of the most unequal countries in Latin America. The high level of informality in the labour market and many characteristics of the pension system leave many elderly in poverty. Only formal-sector employees earning more than the relatively high minimum wage are covered. Linking...

Employment is pivotal to strengthening Greece’s economic recovery, increasing social welfare and redressing poverty. Jobs are returning, making inroads into high unemployment, but their wages and skill levels are lower than many that were lost during the crisis. Greece’s hiring is benefiting...

The recent economic crisis has provided a stress test for the vulnerability of social institutions. This paper assesses the vulnerability of social institutions in light of the current crisis, and surveys past episodes, when social institutions faced similar challenges. Public pay-as-you-go...

When markets are incomplete, social security can partially insure against idiosyncratic and aggregate risks. We incorporate both risks into an analytically tractable model with two overlapping generations. We derive the equilibrium dynamics in closed form and show that joint presence of both...

When markets are incomplete, social security can partially insure against idiosyncratic and aggregate risks. We incorporate both risks into an analytically tractable model with two overlapping generations and demonstrate that they interact over the life-cycle. The interactions appear even though...

We propose a unified framework to measure the effects of different reforms of the pension system on retirement ages and macroeconomic indicators in the face of demographic change. A rich overlapping generations (OLG) model is built and endogenous retirement decisions are explicitly modeled...

This paper investigates whether exchanging the Social Security delayed retirement credit, currently paid as an increase in lifetime annuity benefits, for a lump sum would induce later claiming and additional work. We show that people would voluntarily claim about half a year later if the lump...

We ask whether a PAYG-financed social security system is welfare improving in an economy with idiosyncratic and aggregate risk. We argue that interactions between the two risks are important for this question. One is a direct interaction in the form of a countercyclical variance of idiosyncratic...

Many nations incentivize retirement saving by letting workers defer taxes on pension contributions, imposing them when retirees withdraw their funds. Using a dynamic life cycle model, we show how 'Rothification' - that is, taxing 401(k) contributions rather than payouts - alters saving,...

Urbanisation will continue in China, with the government planning to grant urban residential status to an additional 100 million rural workers by 2020. While this process is transforming the urban economy, the rural economy is also undergoing substantial structural change. Government policy...
