TL;DR: In this paper, a general equilibrium model of both sovereign default and business cycles is proposed, which explains several features of cyclical dynamics around deraults, countercyclical spreads, high debt ratios and key business cycle moments.
Abstract: Emerging markets business cycle models treat default risk as part of an exogenous interest rate on working capital, while sovereign default models treat income fluctuations as an exogenous endowment process with ad-noc default costs. We propose instead a general equilibrium model of both sovereign default and business cycles. In the model, some imported inputs require working capital financing; default on public and private obligations occurs simultaneously. The model explains several features of cyclical dynamics around default triggers an efficiency loss as these inputs are replaced by imperfect substitutes; and default on public and private obligations occurs simultaneously. The model explains several features of cyclical dynamics around deraults, countercyclical spreads, high debt ratios, and key business cycle moments.

TL;DR: In this article, the authors build a dataset on tax rates for 62 countries for the period 1960-2013 that comprises corporate income, personal income, and value-added tax rates and find that tax policy is a cyclical in industrial countries but mostly procyclical in developing countries.
Abstract: It is well known by now that government spending has typically been procyclical in developing economies but a cyclical or countercyclical in industrial countries. Little, if any, is known, however, about the cyclical behavior of tax rates (as opposed to tax revenues, which are endogenous to the business cycle and hence cannot shed light on the cyclicality of tax policy). The authors build a novel dataset on tax rates for 62 countries for the period 1960-2013 that comprises corporate income, personal income, and value-added tax rates. The authors find that, by and large, tax policy is a cyclical in industrial countries but mostly procyclical in developing countries. Further, tax policy in countries with better institutions and or more integrated with world capital markets tends to be less procyclical or more countercyclical.

TL;DR: In this article, the authors extend the model used in recent quantitative studies of sovereign default, allowing policymakers of different types to stochastically alternate in power, and show that a default episode may be triggered by a change in the type of policymaker in office, and that such a default is likely to occur only if there is enough political stability and if policymakers encounter poor economic conditions.
Abstract: We extend the model used in recent quantitative studies of sovereign default, allowing policymakers of different types to stochastically alternate in power. We show that a default episode may be triggered by a change in the type of policymaker in office, and that such a default is likely to occur only if there is enough political stability and if policymakers encounter poor economic conditions. Under high political stability, political turnover enables the model to generate a weaker correlation between economic conditions and default decisions, a higher and more volatile spread, and lower borrowing levels after a default episode.

TL;DR: In this article, the authors identify critical flaws in the traditional approach to evaluate debt sustainability, and examine three alternative approaches that provide useful econometric and model-simulation tools to analyze debt sustainability.
Abstract: The question of what is a sustainable public debt is paramount in the macroeconomic analysis of fiscal policy. This question is usually formulated as asking whether the outstanding public debt and its projected path are consistent with those of the government's revenues and expenditures (ie, whether fiscal solvency conditions hold). We identify critical flaws in the traditional approach to evaluate debt sustainability, and examine three alternative approaches that provide useful econometric and model-simulation tools to analyze debt sustainability. The first approach is Bohn's nonstructural empirical framework based on a fiscal reaction function that characterizes the dynamics of sustainable debt and primary balances. The second is a structural approach based on a calibrated dynamic general equilibrium framework with a fully specified fiscal sector, which we use to quantify the positive and normative effects of fiscal policies aimed at restoring fiscal solvency in response to changes in debt. The third approach deviates from the others in assuming that governments cannot commit to repay their domestic debt and can thus optimally decide to default even if debt is sustainable in terms of fiscal solvency. We use these three approaches to analyze debt sustainability in the United States and Europe after the sharp increases in public debt following the 2008 crisis, and find that all three raise serious questions about the prospects of fiscal adjustment and its consequences.

TL;DR: In this paper, the authors study the sovereign default model that has been used to account for the cyclical behavior of interest rates in emerging market economies and show that this method necessitates a large number of grid points to avoid generating spurious interestrate movements.
Abstract: We study the sovereign default model that has been used to account for the cyclical behavior of interest rates in emerging market economies. This model is often solved using the discrete state space technique with evenly spaced grid points. We show that this method necessitates a large number of grid points to avoid generating spurious interestrate movements. This makes the discrete state technique significantly more inefficient than using Chebyshev polynomials or cubic spline interpolation to approximate the value functions. We show that the inefficiency of the discrete state space technique is more severe for parameterizations that feature a high sensitivity of the bond price to the borrowing level for the borrowing levels that are observed more frequently in the simulations. In addition, we find that the efficiency of the discrete state space technique can be greatly improved by (i) finding the equilibrium as the limit of the equilibrium of the finite-horizon version of the model, instead of iterating separately on the value and bond price functions and (ii) concentrating grid points in asset levels at which the bond price is more sensitive to the borrowing level and in levels that are observed more often in the model simulations. Our analysis is also relevant for the study of other credit markets.

TL;DR: In this article, the interaction between fiscal commitment and sovereign default risk in a model with optimal taxation and government spending is studied, and it is shown that committing to an inflexible tax plan is counterproductive: the lack of tax contingency hurts the government's debt sustainability and reduces welfare.
Abstract: This paper studies the interaction between fiscal commitment and sovereign default risk in a model with optimal taxation and government spending A time-inconsistency problem arises in our framework as the government cannot credibly commit to its future tax policies As a result, it chooses suboptimally low fiscal adjustments and defaults too frequently Introducing a commitment device to future tax policies can mitigate this time-inconsistency problem and improve the government's borrowing opportunities However, such a commitment device also entails a loss of tax contingency that might be costly Our quantitative analysis shows that committing to an inflexible tax plan is counterproductive: the lack of contingency hurts the government's debt sustainability and reduces welfare In contrast, committing to a flexible tax plan that is contingent on future economic conditions can improve debt sustainability by 533% and result in a significant welfare gain

TL;DR: In this paper, the authors assess the consequences of implementing a joint liability debt system in a two-country small open economy model and find that the welfare consequences of this policy proposal hinge critically on the timing of its introduction.
Abstract: This paper assesses the consequences of implementing a joint liability debt system in a two-country small open economy model. With joint liability a default of one country makes the other participant liable for its debt. The results highlight a trade-off between the contagion risk, in the sense that this instrument may push some member states to default even though they are individually solvent, and cheaper access to credit on average, since lenders are at risk only if no participating sovereign is willing to service the debt. The findings suggest that the welfare consequences of this policy proposal hinge critically on the timing of its introduction: Introducing such instruments at the peak of the Eurozone crisis would have helped the Periphery and harm the Core member states, while its adoption during normal times has the potential to make all participants better-off.

TL;DR: The authors found that the response of emerging governments to output uctuations is similar to that of developed governments, however, emerging governments curtail spending in response to increases in the sovereign borrowing rate, which forces their consumption expenditure to act more procyclically.
Abstract: Fiscal procyclicality, meaning co-movement between government expenditure and macroeconomic fundamentals, is an important feature of business cycle dynamics for emerging and poor economies. I estimate a panel SVAR to investigate if fiscal policy leads to heightened volatility, reinforcing the cycle in emerging economies. The analysis also sheds light on the role of external financial constraints in shaping fiscal policy. My findings suggest that the response of emerging governments to output uctuations is similar to that of developed governments. However, emerging governments curtail spending in response to increases in the sovereign borrowing rate, which forces their consumption expenditure to act more procyclically. While I find evidence of higher fiscal discretion in emerging economies, the government consumption multiplier is substantially smaller for this group. For this reason, fiscal policy is responsible for a lower share of business cycle volatility in emerging economies than in developed ones.
