Does capital flow from rich to poor countries? We revisit the Lucas paradox and explore the role of capital account restrictions in shaping capital flows at various stages of economic development. We find that, when accounting for the degree of capital account openness, the prediction of the...

This paper develops a model of the circumstances under which it is beneficial to participate in a currency area. The proposed two-country monetary model of trade with nominal rigidities encompasses the real and monetary arguments suggested by the optimum currency area literature: correlation of...

This paper investigates the relation between agglomeration of economic activity and the pattern of specialization of countries. We develop a model encompassing a Ricardian comparative advantage, increasing returns to scale, product differentiation, monopolistic competition, trade costs, and...

This paper investigates the effects of fixed versus flexible exchange rate regimes on location choices of firms and on the degree of specialization of countries. In a two-country two-differentiated-good monetary model, demand, supply, and monetary shocks arise after wages are set and prices are...

This paper provides a new model of firm's location choices. It integrates a Ricardian model of comparative advantage with the location effects deriving from trade costs, increasing returns to scale, product differentiation, and monopolistic competition. In a two-region, two-differentiated-good,...

This paper develops a two-country model to investigate the circumstances under which it is beneficial to participate in a currency area. It captures both the real and monetary arguments suggested by the optimum currency area literature in a simple monetary model of trade with nominal rigidities....

We propose a new framework for monetary policy analysis to study monetary policy normalization when exiting a liquidity trap. The optimal combination of reserves and interest rate policy requires an increase in liquidity (reserves) a few quarters after the policy rate is set at the effective...

Can currency competition affect central banksícontrol of interest rates and prices? Yes, it can. In a two-currency world with competing cash (material or digital), the growth rate of the cryptocurrency sets an upper bound on the nominal interest rate and the attainable inflation rate, if the...

This paper provides insights into the historical inefficiencies and instabilities of the international monetary system. These inefficiencies are primarily linked to the limited supply of international liquidity and wedges in various money-market rates. The instabilities encompass both...
