Policy myopia arises when rational voters set performance standards that allow elected politicians to distort the portfolio of public investments towards short-term investments. We show that the fact that voters cannot observe immediately how much politicians invested in certain types of public goods is not in itself sufficient to generate policy myopia. Policy myopia, then, arises in societies where electoral control is imperfect or in society where tax revenues cannot be committed in advance. The analysis is motivated by a number of stylized facts about public spending patterns across time and space.

We show that the tax smoothing approach, augmented by fiscal habit considerations, provides a surprisingly accurate description of US budget surplus movements. In order to investigate the robustness of the policy implications of the rule, we construct a real-time US fiscal data set, complementing the data documented by Croushore and Stark (2001). For each variable we record the different vintages, reflecting the remeasurements that occur over time. We demonstrate that the easily constructed rule provided a useful benchmark for policy analysis that is robust to real-time remeasurements.

Stress testing can be seen as a first order test of the level of potential negative outcomes in response to tail shocks. However, the results of stress testing can be misleading in the presence of model error and the uncertainty attending parameters and their estimation. The heuristic can be seen as a second order stress test to detect nonlinearities in the tails that can lead to fragility, i.e., provide additional information on the robustness of stress tests. It also shows how the measure can be used to assess the robustness of public debt forecasts, an important issue in many countries. The heuristic measure outlined here can be used in a variety of situations to ascertain an ordinal ranking of fragility to tail risks. JEL Classification Numbers: G10, G20, G21

Working Papers describe research in progress by the author(s) and are published to elicit comments and to further debate. This paper proposes a new framework for the analysis of public sector debt sustainability. The framework uses concepts and methods from modern practice of contingent claims to develop a quantitative risk-based model of sovereign credit risk. The motivation in developing this framework is to provide a clear and workable complement to traditional debt sustainability analysis which-although it has many useful applications-suffers from the inability to measure risk exposures, default probabilities and credit spreads. Importantly, this new framework can be adapted for policy analysis, including debt and reserve management. JEL Classification Numbers: E61, G13, G15, H63

These measures differ from "banking crisis" (BC) indicators employed in many empirical studies, which are constructed using primarily information on government actions undertaken in response to bank distress. Using both country-level and firm-level samples, we show that SBS indicators consistently predict BC indicators, indicating that BC indicators actually measure lagged policy responses to systemic bank shocks. We then re-examine the impact of macroeconomic factors, bank market structure, deposit insurance, and external shocks on the probability of systemic bank shocks (SBS) and on "banking crisis" (BC) indicators. We find that the impact of these variables on the likelihood of a policy response to banking distress (as represented by BC indicators) is frequently quite different from that on the likelihood of a systemic bank shock (SBS). We argue that disentangling the effects of systemic bank shocks and policy responses is crucial in understanding the roots of banking crises. We believe that many findings of a large empirical literature need to be re-assessed.
