Limits to government debt sustainability in OECD countries

The recent euro area sovereign debt crisis has shown the importance of market reactions for the sustainability of debt in advanced economies. This paper calculates endogenous government debt limits given the markets assessment of the probability to default. The estimated primary balance reaction function to growing debt has the “fiscal fatigue” property (a loosening fiscal effort makes the primary balance insufficient to support rising debt) at high debt levels. The combination of this feature of the primary balance reaction function with the market interest rate reaction to growing debt determines the government debt limit beyond which debt cannot be rolled over. An application to OECD countries over the period 1985 – 2013 with a model-based risk-premium shows that current debt limits are high for most of the OECD thanks to particularly low risk-free interest rates. It also shows for some countries that current debt levels are not sustainable without a change in government behaviour. Most importantly, the framework illustrates the state contingent nature of debt limits and therefore the vulnerability of governments to a change in macroeconomic conditions and to market reactions. Last, computations with an estimated interest rate reaction to public debt illustrate that debt limits are lower in the euro area than in other countries because of a sharper market interest rate reaction to rising debt.     

Public consumption composition in a growing economy

This paper explores the role of the composition of public consumption within a three sector R&D growth model. A competitive industry supplies a homogeneous good and a monopolistic sector manufactures a composite commodity differentiated in many varieties, whose size can be increased through investment in R&D. We investigate the effects of changes in the level and in the composition of public consumption on the steady state and on the economy’s transitional dynamics. By varying the aggregate composition of demand, the government can effectively move resources away from the traditional industry to foster innovation. Welfare effects are also evaluated. We show that the composition of government consumption affects the entire time path of utility.     

Fiscal financing and the efficacy of fiscal policy in Korea: An empirical assessment with comparison to the U.S. evidence

This paper aims to assess the empirical implications of fiscal financing in Korea and study how they differ from those of the U.S. We estimate two versions of the dynamic stochastic general equilibrium (DSGE) model—a small open economy (SOE) model for Korea and its closed economy counterpart for the U.S.—in which the former nests the latter as a special case. The fiscal policy specification posits that government spending, lump-sum transfers, and distortionary taxation on labor income, capital income and consumption expenditures respond to the level of government debt and the state of economic activity. Analysis of the data from 2000 to 2015 shows that distortionary capital taxes play a critical role in stabilizing government debt in the U.S., whereas non-distorting fiscal instruments are the primary means of fiscal adjustment in Korea. Regarding the magnitude of debt-financed fiscal stimuli, the substantial trade openness of Korea is significant in that it produces relatively smaller government spending and transfer multipliers compared to the U.S.     

Fluctuations in convex models of endogenous growth, I: Growth effects

Is there a trade-off between fluctuations and growth? The empirical evidence is mixed, with some studies finding a positive relationship, while others find a negative one. Our objectives are to understand how fundamental uncertainty affects the long run growth rate and to identify important factors determining this relationship in a convex endogenous growth model. Qualitatively, we show that the relationship between volatility in fundamentals (or policies) and mean growth can be either positive or negative. The curvature of the utility function is a key parameter that determines the sign of the relationship. Quantitatively, an increase in uncertainty always increases the growth rate in our calibrated models. Though the changes we find are nontrivial, they are not large enough by themselves to account for the large differences in growth rates observed in the data. We also find that differences in the curvature of preferences have very substantial effects on the estimated variability of stationary objects like the consumption–output ratio and hours worked. For this reason, we expect that the models considered in this paper will provide the basis of sharp estimates of the curvature parameter.     

Human capital aggregation and relative wages across countries

Most of the growth accounting literature relies on an aggregate production function to determine the contribution of factors of production relative to that of total factor productivity (TFP) in explaining differences in incomes across countries. I show that the importance of TFP in accounting for cross-country income differences depends crucially on how skilled and unskilled labor are aggregated. Further, cross-country evidence on the relationship between relative wages and relative endowments of skilled and unskilled labor suggests that the two types of labor should not be aggregated into a single factor of production. Growth accounting decomposition using a commonly used nested-CES aggregate production function that allows skilled and unskilled labor to be used as separate factors of production results in a significantly greater role for TFP in accounting for income differences across countries than that found by past studies. The finding that different aggregate production functions lead to significantly different conclusions about the role of TFP in accounting for cross-country income differences calls for a more general approach to understanding such differences.     

This time truly is different: The cyclical behaviour of fiscal policy during the Covid-19 crisis

Fiscal policy was more countercyclical during the Covid-19 crisis than in previous (crisis) episodes. This paper presents empirical evidence in favour of a “this time truly is different” moment based on analysing the cyclical behaviour of fiscal policy for 28 advanced economies over 1995–2021. Discretionary fiscal policy during the Covid-19 crisis (2020–2021) did more to counteract the downturn – especially in the Eurozone –, as we do not find comparable evidence for countercyclicality during the financial crisis or Euro crisis. Automatic fiscal stabilisers, the non-discretionary domain of fiscal policy, significantly contributed to countercyclical stabilisation during the pandemic.     

Asymmetric effects of fiscal policy in EU and OECD countries

In this article, we take account of an evaluation of the short- and medium-term effects of the transmission mechanism of fiscal policy in EU and OECD countries and their dependence on the state of the economy and fiscal behaviour. Our findings indicate that (i) across EU member states the impact of government spending on economic performance is larger in the accession than in core member states, (ii) since the onset of the economic/financial crisis the government spending multipliers have become larger in both core and accession EU member states, and (iii) a comparison with fiscal responses in the OECD countries shows robustness of our estimates. The conclusion implies that the austerity measures present a substantial drag for economic activity in accession EU countries. Thus, we may state that not considering the fiscal behaviour and state of the economy gives misleading fiscal multiplier effects, which in turn lead to the adoption of inappropriate fiscal measures that even worsen a country's economic situation.     

Sugar daddy u: human capital investment and the university-based supply of ‘romantic arrangements’

To deal with the financial hardships associated with rising college tuition, many female college students in the U.S. are turning to risqué forms of financing human capital investments, such as agreeing to potentially lucrative ‘romantic arrangements’ with older males, referred to as ‘sugar daddies,’ through the largest Internet-based club in the industry. Yet despite this recent trend, there is a relative paucity of published academic research on the economics of such behaviour. Using data from the more than 220 nationally ranked (by U.S. News & World Report’s America’s Best Colleges) colleges and universities in the U.S., presents results from both Poisson and scaled Poisson estimation suggesting that large, high-cost universities that are located in larger cities or where unemployment rates are higher lead the nation in the number of female students choosing such romantic arrangements in order to fund higher education. Moreover, those institutions that are chosen by more physically attractive female students, and those that enrol a higher percentage of female students, are also generating greater numbers of female student entrants into the sugar daddy industry. Each of these findings has implications for the human capital literature and the growing body of academic literature on the economics of beauty.     

Debt,seigniorage, and the Growth Laffer Curve in developing countries

The endogenous growth literature established the existence of an inverted-U curve between taxes and economic growth, namely a Growth Laffer Curve, but empirical evidence on this relationship in developing countries is rather limited. Given that seigniorage and public debt are also important means of financing public spending in these countries, we take into account in this paper their respective impacts on growth, as they might deform the existing relationship between taxes and growth. To this end, we develop a growth model with public investment as the engine of perpetual growth, and look for the effect of debt, tax and money financing on economic growth. We study in particular the way fiscal and monetary policies deform the Growth Laffer Curve in developing countries. An empirical section based on a panel of 100 developing countries over the period 1980–2010 provides both OLS-Fixed Effects and GMM-system estimations that support our theoretical conclusions, namely the existence of Growth Laffer Curves indexed by the levels of debt and of seigniorage.     

Public spending, voracity, and Wagner's law in developing countries

An examination of the short- and long-term relation between government spending and output in 51 developing countries reveals evidence consistent with cyclical ratcheting and voracity reflected in a tendency for government spending to increase over time. The main components of government spending are procyclical in some 40% of countries. Output and government spending are cointegrated for at least one of the spending aggregates in 70% of countries, implying a long-term relationship between government spending and output consistent with Wagner's law. In contrast, prior studies have found only weak support for Wagner's law for developing countries, although somewhat stronger support for industrial countries.     

中国城镇贫困的变化趋势和模式:1988—2002

本文利用中国家庭收入项目(CHIP)调查数据,估计了1988—2002年中国城镇绝对贫困的变化趋势。根据CHIP调查数据所绘制的贫困发生曲线表明,不论把绝对贫困线确定在哪里,在该时期内中国城镇贫困都在显著减少。1988—1995年,收入分配不平等加剧,但此后基本保持稳定。分析收入和贫困决定因素的多元回归模型显示,教育、性别和中共党员等特征扩大了收入差异。来自政府反贫困措施的生活困难救助对减少城镇贫困影响很小。城镇贫困的缓解几乎完全归因于经济增长而非收入再分配。     

Public debt and welfare in a quantitative Schumpeterian growth model with incomplete markets

This paper quantifies the welfare effects of counterfactual public debt policies using an endogenous growth model with incomplete markets. The economy features public debt, Schumpeterian growth, infinitely-lived agents, uninsurable income risk, and discount factor heterogeneity. Two versions of the model are specified, one with households holding equity in the group of innovating firms. The model is calibrated to the U.S. economy to match the degree of wealth inequality, the share of R&D expenditure in GDP, the firms’ exit rate, the average growth rate, and other standard long-run targets. When comparing balanced growth paths, I find large welfare gains in equilibria characterized by governments accumulating public wealth. The result is robust to the mechanism used to generate a highly concentrated wealth (i.e., preference heterogeneity or “superstar” income shocks). Welfare effects decompositions show that level effects and growth effects reinforce each other. The responses of both the intermediate goods and their market conditions are key in explaining the large level effects. The version of the model without equity is computationally easier to solve, allowing to consider transitional dynamics. Taking into account the dynamic adjustment to the new long-run equilibrium, I show that the transitional welfare costs are not large enough to change the sign of the welfare effects stemming from a change in public debt. I find that eliminating public debt would lead to a 0.8% increase in welfare, while moving to a debt/GDP ratio of 100% would entail a welfare loss of 0.5%. A decomposition analysis shows that growth accounts for approximately 50% of the overall welfare effects.     

Growth and inequality in an endogenous fiscal policy model with taxes on labor and capital

I study an economy where individuals have different initial endowments and fiscal policy is decided by majority voting. Public investment is financed by two flat rate taxes, one on labor income and the other one on capital income. The model shows a positive (negative) correlation between growth and the tax rate on labor (capital) income and a negative (positive) correlation between the tax rate on labor (capital) income and inequality. The results reconcile the theory with empirical evidence.     

Cash-in-advance constraint,optimal monetary policy,and human capital accumulation

This paper investigates optimal monetary policy in an overlapping-generations model with endogenous growth fueled by the accumulation of human capital and under a cash-in-advance constraint. We consider the case where the government finances public education fully by seigniorage. Three main results are obtained. First, there exists an optimal money growth rate that maximizes the economic growth rate along the steady growth path. Second, on this path, the Laffer curve of seigniorage takes the maximum. Finally, the money growth rate for maximizing seigniorage along the steady growth path, which also leads to maximization of the economic growth rate, is lower than that for maximizing seigniorage in the present period.     

Labor force growth and the environment in Costa Rica

The introduction to this report of a study that examines the potential environmental impacts of labor force growth (LFG) in Costa Rica under LFG scenarios notes that LFG is an economically critical aspect of population growth that can affect the environment by expanding the economy's production possibilities frontier and/or by increasing consumption. The introduction also explains why Costa Rica is ideal for this study and identifies the study as unique because it constructs a computable general equilibrium (CGE) model using 10 environmental indicators and because it models uncertainty regarding the values of the economic parameters. The report continues by reviewing the literature linking population and environmental issues; detailing the CGE model; discussing the 10 environmental indicators (deforestation, erosion, pesticide use, overfishing, hazardous wastes, inorganic wastes, organic wastes, greenhouse gas emissions, air pollution, and water/sewer usage) used in the model; and explaining the method used to simulate the impacts of LFG. The major conclusions that emerged from the results of this study are that 1) the economy-wide impacts of LFG (and, thus, population growth) on the environment are important and vary significantly according to the amounts of physical and human capital present in the labor force and 2) the impacts of LFG vary substantially among environmental indicators.     

Fiscal policy and private consumption in industrial and developing countries

This paper empirically studies the effects of fiscal policy shocks on private consumption. Further, it investigates if the initial financing needs of the government or previous fiscal deficits affect that relationship. We use yearly data between 1970 and 2000 for 40 countries, of which 19 are industrialized and 21 are developing countries. In general, the estimation results seem to indicate that government consumption shocks have Keynesian effects for both industrial and developing countries. In the case of tax shocks, the evidence is mixed. Furthermore, there is no evidence that favors the hypothesis of expansionary fiscal consolidations.     

Current account dynamics and capital mobility in the newly industrialized countries

This paper examines the current account dynamics in a group of ten newly industrialized countries (NICs) during the period 1980–2012 using a panel error-correction model. The model is also used to empirically test whether the degree of capital mobility is positively related to financial openness. The Chin-Ito (2006, 2008) financial openness index is used to classify the countries into different groups, and we place the countries in one group that are similar to each other in terms of their financial openness. Furthermore, to evaluate the extent of capital mobility over the different period from 1980 to 2012, the total period under study is divided into three sub-periods. The estimation results indicate that there exist long-run equilibrium relationships between domestic saving, investment, and current account in all groups regardless of their degree of financial openness. We find that more openness in terms of the capital account is associated with a higher degree of capital mobility in the case of NICs. The empirical result also indicates that the degree of capital mobility is higher in the first and third sub-period.

欧债危机爆发后,有一种观点认为危机的原因是高福利。通过分析希腊债务危机与本国福利制度的关系,对比南北欧在危机中的不同表现,可以看出高福利制度只是债务危机的直接推手,欧债危机的发生还有其他原因。本文通过对北欧福利国家改革的历史考察以及这次债务危机中各国财政紧缩和福利改革措施的分析,探讨福利国家改革的走向和趋势。     

Human capital accumulation and output growth in a stochastic environment

We study the relationship between growth and volatility in a simple analytical model, where human capital accumulation depends on both deliberate and non-deliberate learning, and where stochastic fluctuations arise from both preference and technology shocks. We derive a number of new results which challenge some of the results in the existing literature. First, we show that the optimal allocations of time to working and learning are both pro-cyclical. Second, we identify a preference parameter (other than the coefficient of relative risk aversion) that is potentially crucial for governing the effect of volatility on growth. Third, we demonstrate how this effect can be either positive or negative under each type of learning, the relative importance of which is irrelevant to the outcome. Fourth, we reveal how the effect may also be different for the two types of shock. Our results may be seen as providing further explanation for the lack of robust evidence on the issue.      

The role of human and social capital in growth: extending our understanding

Human capital, institutions and social capital are now all recognisedas significant factors of growth. They have largely been studiedseparately, and although they present sufficient common characteristicsto be conceptualised as one main category distinct from physicalcapital, it may still be more important to focus on the linksbetween their specific sub-categories. Direct links with incomemay be spurious, as there appears to be a ‘web of associations’between the sub-categories, which would benefit from furtherempirical investigation. This paper reviews the literature onhuman capital, institutions and social capital, extracting threesub-categories of human capital (human skills capital, stock-of-knowledgeand entrepreneurship) and two of social capital (low- and high-rationalisation).Specific areas are then suggested for further empirical study.
