This paper evaluates the effect of market integration on prices and welfare, in a model where two Lucas trees grow in separate regions with similar investors. We find equilibrium asset price dynamics and welfare both in segmentation, when each region holds its own asset and consumes its...

We review the international finance literature to assess the extent to which international factors affect financial asset demands and prices. International asset-pricing models with mean-variance investors predict that an asset's risk premium depends on its covariance with the world market...

Evidence suggests that international capital markets are neither fully integrated nor completely segmented. There is, however, currently no general method available for computing the required return on corporate investments with such capital markets. This paper uses a model of partially...

Is asset pricing segmented or integrated in frontier equity markets? To answer this question, we examine the returns on more than 4,500 stocks from 22 frontier countries for the years 1997–2018. We evaluate the performance of a few major asset pricing models. We document strong value and...

The paper examines how a movement from segmented markets to integrated markets affects the volume of trade, consumer prices, profits and welfare in a monopoly model. The monopolist can initially discriminate consumer prices among markets with trade costs but has to take arbitrage into account as...

We develop a model in which financially constrained arbitrageurs exploit price discrepancies across segmented markets. We show that the dynamics of arbitrage capital are self-correcting: following a shock that depletes capital, returns increase, and this allows capital to be gradually...
