Using consistent agent-based techniques, this research explores the welfare consequences of product differentiation on congested networks. The economic analysis focuses on the source, evolution, measurement, and impact of product differentiation with heterogeneous users on a mixed ownership...

We examine the role of commercial banks in monetary transmission in a factor-augmented vector autoregression (FAVAR). A FAVAR exploits a large number of macroeconomic indicators to identify monetary policy shocks, and we add commonly used lending aggregates and lending data at the bank level....

The promising prospect of a ‘New Economy’ in the US attracted substantial equity inflows in the late 1990s, helping to finance the country’s burgeoning current account deficit. After peaking in 2000, however, US stocks fell by some 8 trillion dollars in value. To assess the welfare effects...

Using Krugman's (1991) target zone model, we find an explicit, sub-game perfect solution for a central bank wishing to stabilize the exchange rate given proportional costs of intervention. We demonstrate, however, that precommitment to narrower bands would yield a welfare gain - which provides a...

Recent empirical research by Mark Taylor and co-authors has found evidence of hybrid dynamics for real exchange rates. While there is a random walk near equilibrium, for real exchange rates some distance from equilibrium there is mean-reversion which increases with the degree of misalignment. An...

The stylised facts of currency crises in emerging markets include output contraction coming hard on the heels of devaluation, with a prominent role for the adverse balance-sheet effects of liability dollarisation. In the light of the South East Asian experience, we propose an eclectic blend of...

The Argentine convertibility regime, where the peso was fixed at parity with the US dollar, ended with a ‘twin crisis’ – a tripling in the price of a dollar and a protracted closure of the entire banking system – accompanied by an economic contraction so severe that it is often referred...

Two key issues are examined in an integrated framework: the emergence of global imbalances and the precautionary motive for accumulating reserves. Standard models of general equilibrium would predict modest current account surpluses in the emerging markets if they face higher risk than the US...

The risk premium in the US stock market has fallen far below its historic level, which Shiller (2000) attributes to a bubble driven by psychological factors. As an alternative explanation, we point out that the observed risk premium may be reduced by one-sided intervention policy on the part of...

When the risk premium in the US stock market fell substantially, Shiller (2000) attributed this to a bubble driven by psychological factors. An alternative explanation is that the observed risk premium may be reduced by one-sided intervention policy on the part of the Federal Reserve which leads...
