International Welfare Spillovers Of National Pension Schemes, James Staveley-O'Carroll, Olena Staveley-O'Carroll
International Welfare Spillovers Of National Pension Schemes, James Staveley-O'Carroll, Olena Staveley-O'Carroll
Economics Department Working Papers
We employ a two-country overlapping-generations model to explore the international dimension of household portfolio choices induced by the asymmetric provision of government-run pensions. We study the resulting patterns of risk-sharing and the corresponding welfare effects on both home and foreign agents. Introducing the defined benefits pay-as-you-go system at home increases the welfare of all other agents at the expense of the home workers and improves the degree of intergenerational risk sharing abroad. Conversely, a defined contributions system leads to welfare losses of both home cohorts accompanied by gains abroad, but does increase the extent of intergenerational risk sharing at home.

International Risk Sharing In Overlapping Generations Models, James Staveley-O'Carroll, Olena M. Staveley-O'Carroll
Economics Department Working Papers
We present a solution to the Backus-Smith puzzle that, instead of relying on extreme parameter values or complex modeling assumptions, simply switches the framework from infinitely lived agents to overlapping generations. Young agents face non-diversifiable wage risk that leads to a low degree of risk sharing within each country. Subsequently, international price movements are not sufficient to achieve the high consumption-real exchange rate correlation produced in standard infinitely lived agent DSGE models.
Nonlinearities In The Real Exchange Rates: New Evidence From Developed And Developing Countries, Yamin S. Ahmad, Ming Chien Lo, Olena M. Staveley-O'Carroll
Nonlinearities In The Real Exchange Rates: New Evidence From Developed And Developing Countries, Yamin S. Ahmad, Ming Chien Lo, Olena M. Staveley-O'Carroll
Economics Department Working Papers
This paper investigates nonlinearities in the dynamics of real exchange rates. We use Monte Carlo simulations to establish the size properties of the Teräsvirta-Anderson (1992) and the Teräsvirta (1994) test, when the dynamics of the real exchange rate is influenced by an exogenous process. In addition, we examine the modification proposed by Ahmad, Lo and Mykhaylova (2013; Journal of International Economics) to show that the modified nonlinearity test performs much better than the original in both Monte Carlo exercises and in the actual data on 1431 bilateral real exchange rate series. Finally, we investigate the dynamics of the real exchange …
Exchange Rate Targeting In The Presence Of Foreign Debt Obligations, James Staveley-O'Carroll, Olena M. Staveley-O'Carroll
Exchange Rate Targeting In The Presence Of Foreign Debt Obligations, James Staveley-O'Carroll, Olena M. Staveley-O'Carroll
Economics Department Working Papers
We study the impact of foreign debt on the trade-off between the three open economy objectives of a central bank - international risk sharing, the need to facilitate expenditure-switching, and the incentive to tilt international prices to lower the labor effort of domestic households - in a two-country DSGE model with incomplete asset markets and deviations from the purchasing power parity. We find that at low debt levels, a Taylor rule outperforms simple targeting rules. However, the central bank can improve welfare by up to 0.25 percent of consumption via an exchange rate peg when debt-to-GDP ratio reaches 100 percent.
