Fiscal sustainability in the wake of the economic crisis in Korea

The total amount of government debt was expected to rise sharply over the following several years in the wake of the Korean financial and economic crisis in 1997, raising concern about the sustainability of government deficits and fiscal consolidation. This paper provides an overview of Korea’s fiscal stance after the financial crisis and the policy implications for fiscal consolidation by assessing fiscal sustainability. Sustainability tests are carried out and show that Korean fiscal policy for the period 1970–1999 should be regarded as sustainable. Indicators of sustainability are also measured to that Korean fiscal policy for the period 1970–1996 is sustainable. However, both the primary and tax gap indicators with a sharp rise in the debt ratios are shown to be worsening since 1997 indicating increasingly possible unsustainable fiscal policies. It implies that the current primary deficit is too large and current taxes are too low to stabilize the debt ratio.     

Credible Carbon Policy

The paper sets out the credibility problem in carbon policy,provides a number of examples of non-credibility in recent energypolicy, and identifies the costs of failing to address it. Thetime inconsistency of carbon policy—arising because ofmultiple objectives, the irreversibility of energy investments,and the scope for ex-post reneging on ex-ante commitments toset policy instruments, such as carbon taxes or emission permits,at appropriate levels—is set in a conceptual framework.Analogies with monetary policy are drawn, and a solution tothe time-inconsistency problem is proposed through the establishmentof an energy/carbon agency.     

LABOUR SKILLS AND HUMAN CAPITAL IN THE EXPLANATION OF TRADE PATTERNS

In the discussion of the qualitative inferences to be drawnfrom the signs of _s and c₃ [OEP 43.2 p. 448], possibilities(ii), (iii) and (iv) and the beginning of the immediately followingparagraph should read:

1. if both _s and c₃ are positive and ß₃₁> ß₃₂
2. if _s is positive and c₃ is negative theneither ß₃₁and ß₃₂ are both positive andß₃₁ > ß₃₂,or they are both negativeand |ß₃₂|>|ß₃₁|,or ß₃₁ ispositive and ß₃₂ is negative.
3. if _sis negative andc₃ is positive then either ß₃₁and ß₃₂ areboth positive and ß₃₂ < ß₃₁,or theyare both negative and |ß₃₁| > |ß₃₂|,or ß₃₁ is negative and ß₃₂ is positive.

Notice that without first confirming that _s = 0 when c³ 0 nothingmuch can be said about the factor content of trade by lookingat c₃ alone; for, in terms of signs of ß₃₁ and ß₃₂,c₃ < 0 precludes only the combination (ß₃₁ <0 & ß₃₂ > 0); and c₃ > 0 precludes onlythe combination (ß₃₁ > 0 & ß₃₂ <0). Similarly...     

ANNOUNCEMENTS AND CREDIBILITY OF MONETARY POLICY

An infinitely repeated monetary policy game à la Barroand Gordon is considered. Before the game starts the governmentannounces a policy rule. If there is a slight probability thatgovernment is honest and a slight probability that the governmentmakes mistakes, then a sufficiently patient government willhave average loss close to its commitment loss in all sequentiallyrational equilibria of the infinitely repeated game.     

Devaluation,Debt, and Default in Emerging Economies

We explore the interactions between exchange rate and fiscal policy, and default on external debt. Exchange rate policy affects the supply of short-term debt facing the government. Under a conventional soft peg, it can be optimal for the government to set the exchange rate at a level in which partial default occurs. In this case multiple equilibria exist, with one featuring high interest rate, overvalued exchange rate, low level of output, and default. Default is also an equilibrium under a hard peg, precisely because devaluation is not an option. Under a hard peg, however, there is a unique equilibrium.

The Assessment: Climate-Change Policy

The paper provides a guide to climate-change policy, and, inparticular, the three core components: targets, instruments,and institutional structures. First, the optimal path for reducingcarbon-dioxide (CO₂) emissions, and the role of the social costof carbon in the estimation and revision of the path are setout. Second, the policy instruments, or combination of instruments—taxes,permits, and command-and-control—which are likely to bemost efficient within the political constraints are reviewed.Finally, the design of institutional structures most conduciveto the facilitation of international agreements (such as theKyoto Protocol) and the establishment of credible global climate-changepolicies is discussed. The paper identifies the considerableinefficiencies in existing policies, and the scope for policyimprovements.     

Fiscal Stabilization Policy and Fiscal Institutions

In this paper we analyse counter-cyclical fiscal policy withinthe context of a microfounded analysis of business-cycle stabilization.We show that tax and spending instruments can have a usefulcounter-cyclical role, even after allowing for the distortionarynature of the instruments and the need for debt sustainability.A critical barrier to the use of fiscal instruments may be politicaleconomy concerns, and we survey recent suggestions involvingalternative fiscal policy institutions.

FISCAL SUSTAINABILITY AND THE FISCAL REACTION FUNCTION FOR SOUTH AFRICA: ASSESSMENT OF THE PAST AND FUTURE POLICY APPLICATIONS

How does the South African government react to changes in its debt position? In investigating this question, this paper estimates fiscal reaction functions using various methods (ordinary least squares, threshold autoregressive, state‐space modelling and vector error‐correction model). This paper finds that since 1946, the South African government has run sustainable fiscal policy by reducing the primary deficit or increasing the surplus in response to rising debt. Looking ahead, this paper considers the use of fiscal reaction functions to forecast the debt/gross domestic product (GDP) ratio and gauging the likelihood of achieving policy goals with the aid of probabilistic simulations and fan charts.     

Beggar thy Neighbor? The Transmission of Fiscal Shocks from the US to Canada

This paper investigates how innovations in income taxes and government expenditures originating in the US affect the US economy, and how these effects are transmitted to the Canadian economy. Using a semi-structural VAR model and data for both countries for the 1961:1–2004:3 period, we find that fiscal policy innovations originating in the US are transmitted to the Canadian economy by international trade and capital flows through interest rate and exchange rate channels. Unanticipated shocks to US government expenditures have beggar thy neighbor effects on Canada. US output increases and Canadian output decreases in response to a positive shock to US government expenditures. In response to an unanticipated increase in US income taxes, US output declines while US and Canadian real interest rates rise. The response of Canadian output, however, is not significantly different from zero.

Impacts of macroeconomic policies on the Mexican output

This paper examines the potential effects of macroeconomic policies, stock market performance, exchange rate fluctuations, and other related variables on real GDP in Mexico. Extending the works by Arango and Nadiri (1981) and Bahmani‐Oskooee and Ng (2002), and applying comparative‐static analysis, possible effects of a change in the exchange rate or government debt on the equilibrium output are examined. All the variables have unit roots and are stationary in first difference. There is a long‐run stable relationship between real GDP and the right‐hand‐side variables. The GARCH(p,q) (Engle 2001) model is applied to estimate regression parameters. Real GDP is positively associated with real M2, government deficit spending, stock prices, U.S. output, and world oil prices, and negatively affected by the government debt ratio, peso depreciation, and the expected inflation rate. Therefore, fiscal policy to incur more debt needs to be pursued with caution, and both net exports and money demand need to be considered in studying the impact of exchange rate fluctuations on output.     

Will Social Welfare Expenditures Survive Tax Competition?

Increasing economic openness creates demands for social welfareprogrammes designed to cushion the impact of economic changes,but may also encourage governments to reduce tax rates to attractmobile economic resources. Competitive tax reductions couldthen prevent governments from being able to finance significantwelfare spending. Alternatively, economic globalization mightimprove the ability of governments to afford social welfareprogrammes—and several considerations point in this direction.First, taxes on internationally mobile activity represent onlysmall fractions of total revenue collections; personal incometaxes, value-added taxes, and social insurance contributionsfinance most social welfare spending. Second, internationalcompetition need not reduce taxes, and indeed, over the past25 years, corporate tax collections have remained high as fractionsof GDP and total taxes. Third, the vitality of a country's economylargely determines its level of social spending. To the extentthat incomes rise as a result, greater economic openness shouldstrengthen provision of social welfare. Footnotes ¹ E-mail address: jrhines{at}umich.edu     

Asset stocks and flows in macroeconomic theory: Resolving the ambiguities in the general IS-LM model

Summary In this paper we have critically examined the macroeconomic model developed by Benavie as a generalization of the beginning-of-period model of Tobin and of Patinkin's end-of-period approach. We have focused our attention on the ambiguous effects on income of government spending changes and tax changes that result from this model. Our conclusions are twofold. First, with respect to the effects of government spending on equilibrium income, we find that, if the demand function for money is decreasing in the interest rate, then the effect of government spending onY is unambiguously positive for any value of. The ambiguity discovered by Benavie is a result of his implicit assumption that money has the characteristics of a Giffen good. Second, in the case of the tax ambiguity, we find the source of the problem to be in the particular formulation of Benavie's asset demand functions. Benavie specifies his asset demand functions in such a way that tax changes impinge directly on these demands. If both stock and flow demands depend upon gross income and not taxes, then there isno ambiguity with respect to tax changes regardless of the value of. However, if both stock and flow demands depend upon disposable income, and hence taxes, the effect of tax changes on equilibrium income becomes ambiguous, but again independently of the value of.     

Regulatory Policy: OECD Experience and Evidence

In the past 20 years a key topic of public-sector reform inOECD countries has been the emergence of regulatory policy.During this period, the nature of regulation has undergone profoundand rapid change. This paper reviews the development of regulatorypolicy in OECD countries over the last quarter-century. It identifiesa range of tools and institutions that have been used by OECDcountries to develop high-quality regulation. The analysis attemptsto show that while there is considerable commonality on broadobjectives of regulatory policy, considerably diversity remainsin the implementation of regulatory policy across OECD countries.

Government budget,public-sector wages and capital taxes in a small open economy: A Hong Kong case

This paper examines the welfare implications of adjustments in public-sector wages and capital tax rates for a small open economy in a general equilibrium setting. The individually and jointly optimal wage and tax policies are derived and interpreted. Facing reductions in land sales and falls in foreign interest rates, a cut in public workers' pay is needed to make their wage comparable to the private sector and a hike in capital taxes is recommended for a budgetary consideration. Using a computable general equilibrium model for Hong Kong, we numerically evaluate the various optimal policies which not only confirm the theoretical results but also provide quantitative estimates of the optimal policy variables.     

The Assessment: Gender and the Life Cycle

This assessment is an introduction to the Oxford Review of EconomicPolicy's issue on gender and the life cycle. It sets the stageby providing background information on various dimensions ofgender differences, pointing out differences across countriesas well as over time, and relates this evidence to the papersthat follow. It further briefly reviews the articles in theissue and puts them into context. Footnotes ¹ E-mail address: c.dustmann{at}ucl.ac.uk     

Export Currency Pricing and Fiscal Multipliers

This paper develops a small open economy dynamic stochastic general equilibrium model to study the implications of the use of foreign currency in export pricing for fiscal policy in East Asian economies. The result shows that external currency pricing amplifies the effect of an exogenous government spending shock on output. The impact and cumulative multipliers are larger under external currency pricing. However, the result depends on the government policy regime. When the government allows for a systematic response of government spending to public debt, the multipliers in the medium-term are smaller under external currency pricing.     

Regional impact of commuter wage taxes

This paper presents a model of interurban and intraurban location that is used to consider the impact of wage taxes on housing and labor markets in a metropolitan area. The focus of the paper is to examine the differences in the regional impact of commuter wage taxes (source-based wage taxes) and residents-only wage taxes (residence-based wage taxes). The model illustrates that suburban land rent and wages can be affected in equilibrium by central city policies and that the mix of public goods (that is, whether they benefit households or firms) as well as those who bear the burden of financing them has implications regarding land values and shifts in relative population and production. Understanding such linkages is important in the creation and analysis of regional economic policy.
