This paper investigates budgetary rules for an economy characterized by inflation and volatile relative prices. We view the budgetary process as a limited contingencies contract between the treasury and the ministers. The budgetary process allows a minister, whose realized real budget falls short of a threshold, to ask for a treasury, the minister obtains the extra funds needed to meet the expenditure threshold level. The contract sets both the projected budget and the threshold real expenditure that justifies budget revisions. We identify the efficient contract and show that for significant state verification costs and for low volatility, the contract is non contingent (i.e., a nominal contract). For volatility significant enough the contract becomes state contingent -- it reduces the initial allocation [i.e., the projected budget,] and reduces the threshold associated with budgetary revisions. Both adjustments imply that in volatile economies the projected revenue understates the realized budget hence the average budget error is positive. As volatility increases, the contract converges to a full ex-post indexation. Hence, one of the costs of inflation is that nominal contracts lose their disciplining role in determining the real allocation. Instead, the economy shifts towards more costly arrangements like ex-post indexation, where discipline is accomplished by constant monitoring The last part of the paper uses the data from 12 Latin American countries to test the model's predictions. Our tests confirm that in an inflationary environment the planned budget is under-predicting the realized one -- higher inflation increases the budget error and the average budget error is positive.

This paper documents the evidence for a productivity based model of the dollar/euro real exchange rate over the 1985-2001 period. Authors estimate cointegrating relationships between the real exchange rate, productivity, and the real price of oil using the Johansen (1988) and Stock-Watson (1993) procedures. They find that each percentage point in the US-Euro area productivity differential results in a five percentage point real appreciation of the dollar. This finding is robust to the estimation methodology, the variables included in the regression, and the sample period. Authors conjecture that productivity-based models cannot explain the observed patterns with the standard set of assumptions, and describe a case in which the model can be reconciled with the observed data.

This paper explores optimal fiscal policy in an overlapping-generations general-equilibrium model under uncertainty and the impact on optimal policy of the introduction of a type of policy stickiness intended to account for the stylized fact that major reforms happen infrequently. In general, our analysis suggests not only that action should not be delayed, but further that action should actually be accelerated. The added realism of restrictions on the frequency of policy changes alters this result in two ways. The prospect of being unable to set policy in the future occasions even more precautionary saving today, if the government acts. However, the government may also choose not to set policy, and its inaction range is very asymmetric. Because the impact of its policies on the current elderly cannot be reversed in the future, the government is much more likely to choose inaction when fiscal tightening is called for. Thus, the optimal policy response over time might best be characterized by great caution in general, but punctuated by occasional periods of apparent irresponsibility.
