چکیده انگلیسی

This paper explores empirically how the adoption of IMF programs affects sovereign risk over the medium term. We find that IMF programs significantly increase the probability of subsequent sovereign defaults by approximately 1.5–2 percentage points. These results cannot be attributed to endogeneity bias as they are supported by specifications that explain sovereign defaults and program participation simultaneously. Furthermore, IMF programs turn out to be especially detrimental to fiscal solvency when the Fund distributes its resources to countries whose economic fundamentals are already weak. Our evidence is therefore consistent with the hypothesis that debtor moral hazard is most likely to occur in these circumstances. Other explanations that point to the effects of debt dilution and the possibility of IMF triggered debt runs, however, are also possible.

مقدمه انگلیسی

When the banking panic of the years 2007/2008 endangered the stability of the world-wide financial system governments stepped in by providing a mixture of generous public guarantees and fiscal stimulus. Since then, the resulting large primary deficits and swollen debt burdens of many countries have brought sovereign risk back on the agenda of investors, policy makers and economists alike. Even among developed economies some countries - most notably Greece - experienced a dramatic loss of market confidence and saw the interest rates on their debt skyrocketing. In the search for a solution to the problem of looming debt crises politicians of the European Union (EU) turned toward the International Monetary Fund (IMF or Fund). Albeit its Articles of Agreement do not provide the IMF with an explicitly stated mandate to fight sovereign debt crises1 the Fund’s Executive Board answered the calls by approving a € 30 billion Stand-By Arrangement for Greece on May 09, 2010 which was supplemented by further EU loans. Spreads on Greece’s ten year government bonds relative to Germany’s, however, did not return to pre-crisis levels, a mere 0.5 percentage points in the average, measured from the introduction of the Euro in 2001 to the end of 2009. Instead, in August 2010 the spread averaged 8.5 percentage points, not far below its maximum of 10.4 recorded on the last trading day before the announcement of the rescue package.2 What has gone wrong? Surely, markets did not fail to realize that the exceptional large lending amount covers Greece’s estimated liquidity needs for an extended period. Are there therefore other reasons to expect that IMF program participation is detrimental to fiscal solvency over a longer horizon? Have previous IMF programs exerted a positive or a negative influence on sovereign risk? Only few authors have addressed these important questions explicitly, which is surprising in face of the vast literature on the economic effects of IMF interventions.3 Consequently, our paper aims to fill this gap by providing a first empirical study that relates program participation to actual default incidences. Before turning to our empirical analysis it is useful to review the theoretical literature on the relationship between IMF interventions and sovereign risk. This literature identifies four channels through which the IMF’s presence alters the probability of subsequent sovereign defaults. These channels focus on the direct effects of liquidity provision, its influence on the governments’ adjustment effort and on the role of conditionality and seniority respectively. Our analysis, however, does not provide us with a clear-cut answer to the question whether we should expect default probabilities to rise or to decrease in the aftermath of IMF programs. Rather, the sign of the effect is disputed even at the level of the individual channels. Liquidity provisions for example may as well prevent (Fischer, 1999) as trigger a run on sovereign debt (Zettelmeyer, 2000). Furthermore, even if emergency lending successfully fends off looming liquidity crises, it will also change the incentives of local policy makers regarding their own adjustment effort. The strength of economic fundamentals partly determines whether this results in a more prudent or a laxer macroeconomic policy with corresponding consequences for long run sovereign risk (Corsetti et al., 2006 and Morris and Shin, 2006). The IMF therefore typically links the disbursement of money to conditions which are designed to guarantee a sustainable policy path, their impact, however, is often impaired by a lack of compliance. Finally, its role as a de facto senior creditor enables the IMF to lend at lower interest rates which clearly benefits the sovereign debtor and private creditors alike (Saravia, 2010). Large additional amounts of official lending, however, also increase the risk of future solvency crises in the same way private lending does. A default on more junior private debt may therefore become more and not less likely (Boz, 2011). While the specific characteristics of IMF lending programs affect sovereign risk in several ambiguous ways even less is known on the aggregate effect of program participation on the likelihood of sovereign debt crises. We therefore investigate the IMF-default relationship empirically using univariate and bivariate probit methods. Summarizing our main results, we find that IMF programs significantly increase the risk of subsequent sovereign defaults by approximately 1.5–2 percentage points. This finding can not be attributed to endogeneity bias since the results for a specification that explains sovereign defaults and program participation simultaneously strengthen our conclusions. Neither can the results be explained by a lack of compliance with IMF conditionality. Further empirical exercises show that the magnitude of the effect depends on economic fundamentals in a way consistent with economic theory. However, we do not find a default-risk reducing effect of IMF interventions in any of our specifications. Hence, we conclude that the adoption of an IMF program seems to be no good news at all for private long-term creditors. The present paper is organized as follows: Section 2 reviews the theoretical and empirical literature on the relationship between IMF programs and sovereign debt crises. Our empirical framework and our data basis are laid out in Section 3. Section 4 presents the results. Section 5 concludes this paper.

نتیجه گیری انگلیسی

Although the IMF features prominently both in the history of sovereign debt crises and in recent policy proposals aimed at the prevention of such crises, surprisingly little is known on the effects of IMF program participation on the likelihood of subsequent defaults. In light of the inconclusive findings in the theoretical literature this paper attempts to investigate this issue empirically. Using univariate and bivariate probit specifications our results indicate that the adoption of an IMF program increases sovereign risk over the medium term. More concretely, we estimate that the probability of a sovereign default increases by approximately 1.5–2 percentage points in the aftermath of IMF programs. These findings cannot be contributed to a lack of compliance with conditionality but seem to reflect the effects of IMF interventions per se. Financial markets’ cautious reaction to Greece’s rescue package described in the introduction of this paper thus seems legitimate in the light of these results. Further analyses additionally show that IMF programs are especially detrimental to fiscal solvency when Fund resources are targeted to countries with already weak fundamentals. Overall, our evidence is therefore consistent with the idea that debtor moral hazard is most likely to occur in these situations as predicted by the theoretical work on the catalytic finance hypothesis. Other explanations that point to the effects of debt dilution and the possibility of IMF triggered debt runs, however, are also possible. The separation of the effects in terms of these different explanations surely constitutes an interesting area for future research. Regarding the policy implications of our findings, one important qualification has to be kept in mind before concluding that debt crises would become less likely in a world without IMF interventions. Since the pure existence of the IMF as a potential international lender of last resort may deter short-run creditors from running it is possible that the Fund has prevented several debt crises without being active. This possibility, however, should not preclude the IMF from a thorough analysis of the question whether too many resources have been devoted to countries which view IMF lending as a substitute for, rather than a complement to policy reform.
