This paper discusses desirable exchange rate regimes and how countries can shift from their current regimes to these regimes over the medium term. We demonstrate the superiority of a basket-peg regime with the basket weight rule over a floating regime with the interest rate rule or the money...

This paper analyzes the optimal transition of the exchange rate regime in the People’s Republic of China (PRC). How the PRC can successfully reach the desired regime—whether a basket peg or floating regime—from the current dollar-peg regime remains a major question. To...

This paper offers empirical evidence that real exchange rate volatility can have a significant impact on long-term rate of productivity growth, but the effect depends critically on a country's level of financial development. For countries with relatively low levels of financial development,...

I analyze how lack of commitment affects the maturity structure of sovereign debt. Governments balance benefits of default induced redistribution and costs due to income losses in the wake of a default. Their choice of short- versus long- term debt affects default and rollover decisions by...

We analyze economic rationales for, and possible alternatives to, the Stability and Growth Pact (SGP). We identify various cross-country spillover effects and domestic policy failures as potential rationales. The two sets of problems suggest different corrective measures, and different measures...

We extend "economic equivalence" results, like the Ricardian equivalence proposition, to the political sphere where policy is chosen sequentially. We derive conditions under which a policy regime (summarizing admissible policy choices in every period) and a state are "politico-economically...

We analyze the short and long run effects of demographic ageing—increased longevity and reduced fertility—on per-capita growth. The OLG model captures direct effects, working through adjustments in the savings rate, labor supply, and capital deepening, and indirect effects, working through...

We develop a sovereign debt model with official and private creditors where default risk depends on both the level and the composition of liabilities. Higher exposure to official lenders improves incentives to repay but carries extra costs, such as reduced ex-post flexibility. The model implies...

We shed light on the function, properties and optimal size of austerity using the standard sovereign debt model augmented to include incomplete information about credit risk. Austerity is defined as the shortfall of consumption from the level desired by a country and supported by its repayment...
