Determinants of spreads on sovereign bank loans: the role of credit history

This paper is an empirical investigation into the role of credit history in determining the spread on sovereign bank loans. It employs an error-in-variables approach used in rationalexpectations-macro-econometrics to set up a structural model that links sovereign loan spreads to realized repayment behavior. Unlike the existing empirical literature, its instrumental variables method allows for distinguishing a direct influence of past repayment problems (a “pure reputation ” effect) from one that goes through increased default probabilities. Using developing country data from the period 1973-1981 and constructing continuous variables for credit history, we find that past default is a significant determinant of the spread, even after including country fixed effects. Moreover, its reduced-form effect is very similar to its structural form effect, indicating that most of the influence of past repayment problems is through the reputation channel. Overall, reserves to imports, past and predicted future default are substantial determinants of sovereign bank loan spreads

Monetary Policy and Stock Market Booms

Historical data and model simulations support the following conclusion. Inflation is low during stock market booms, so that an interest rate rule that is too narrowly focused on inflation destabilizes asset markets and the broader economy. Adjustments to the interest rate rule can remove this source of welfare-reducing instability. For example, allowing an independent role for credit growth (beyond its role in constructing the inflation forecast) would reduce the volatility of output and asset prices.inflation targeting, sticky prices, sticky wages, stock price boom, DSGE model, New Keynesian model, news, interest rate rule

Monetary policy and stock market boom-bust cycles

We explore the dynamic effects of news about a future technology improvement which turns out ex post to be overoptimistic. We find that it is difficult to generate a boom-bust cycle (a period in which stock prices, consumption, investment and employment all rise and then crash) in response to such a news shock, in a standard real business cycle model. However, a monetized version of the model which stresses sticky wages and a Taylorrule based monetary policy naturally generates a welfare-reducing boom-bust cycle in response to a news shock. We explore the possibility that integrating credit growth into monetary policy may result in improved performance. We discuss the robustness of our analysis to alternative specifications of the labor market, in which wage-setting frictions do not distort on going firm/worker relations.

Ambiguity Aversion: Implications for the Uncovered Interest Rate Parity Puzzle

High-interest-rate currencies tend to appreciate in the future relative to low-interest-rate currencies instead of depreciating as uncovered-interest-parity (UIP) predicts. I construct a model of exchange-rate determination in which ambiguity-averse agents face a dynamic filtering problem featuring signals of uncertain precision. Solving a max-min problem, agents act upon a worst-case signal precision and systematically underestimate the hidden state that controls payoffs. Thus, on average, agents next periods perceive positive innovations, which generates an upward re-evaluation of the strategy's profitability and implies ex-post departures from UIP. The model also produces predictable expectational errors, ex-post profitability and negative skewness of currency speculation payoffs.uncovered interest rate parity, carry trade, ambiguity aversion, robust filtering
