A stochastic volatility model where volatility was driven solely by a latent variable called news was estimated for three stock indices. A Markov chain Monte Carlo algorithm was used for estimating Bayesian parameters and filtering volatilities. Volatility persistence being close to one was...

Following a brief review of the recent history of GDP-linked instruments, this paper proposes a set of tools to examine the quantitative properties of GDP-linked warrants. It argues that trigger conditions should be clearly identifiable and payment amounts easily calculable. Based on a design...

Fiscal rules are being increasingly used by both emerging and developed economies. This paper analyzes two alternative fiscal policy rules in terms of their impact on debt sustainability: a rule that fixes the ratio of primary surplus to GDP (""fixed surplus rule"") and one that sets the primary...

In a recent paper, Bai and Perron (2006) demonstrate that their approach for testing for multiple structural breaks in time series works well in large samples, but they found substantial deviations in both the size and power of their tests in smaller samples. We propose modifying their...

VAR methods suggest that the monetary transmission mechanism may be weak and unreliable in low-income countries (LICs). But are structural VARs identified via short-run restrictions capable of detecting a transmission mechanism when one exists, under research conditions typical of these...

This paper documents the specification of a model that was constructed to assess debt sustainability in emerging market economies. Key features of the model include external and fiscal sectors, which allow assessment of external and public debt in a unified framework; public and external debt,...

We investigate the properties of Johansen''s (1988, 1991) maximum eigenvalue and trace tests for cointegration under the empirically relevant situation of near-integrated variables. Using Monte Carlo techniques, we show that in a system with near-integrated variables, the probability of reaching...

Growth-indexed bonds have been suggested as a way of reducing the procyclicality of emerging-market countries'' fiscal policies and the likelihood of costly debt crises. Investor attitude surveys suggest that pricing difficulties are seen as a considerable obstacle. In an effort to reduce such...

In oil-dependent countries, a major issue is how to stabilize fiscal spending when government revenue fluctuates along with the international price of oil. A stabilization fund would allow the government to pull through an oil price trough and absorb windfall revenue when prices are high. This...

This paper analyzes the effects of including collective action clauses (CACs) and enhanced CACs in international (nondomestic law-governed) sovereign bonds on sovereigns' borrowing costs, using secondary-market bond yield spreads. Our findings indicate that inclusion of enhanced CACs, introduced...
