THE ECONOMICS OF THE GOVERNMENT BUDGET CONSTRAINT

This article summarizes the simple analytics of the macroeconomiceffects of government budget deficits. The presentation is organizedaround three key relationships: the national income accountsbudget deficit identity, the deficit financing identity, andthe dynamic equation for the evolution of the ratio of publicdebt to gross national product. The national income accountsidentity highlights the effect of the deficit on domestic savingand investment and the current account. Examining the financingof the deficit brings to light the different kinds of macroeconomicimbalance the deficit can cause—as a first approximation,printing money excessively shows up as inflation, excessiveuse of foreign reserves leads to crises in the balance of payments,high foreign borrowing leads to a debt crisis, and too muchdomestic borrowing leads to high real interest rates and crowdingout of private investment. The debt dynamics equation is usedto show the long-run constraints on fiscal policy.      

Lessons from Experiences with High Inflation

In economies where price control has been the rule, the mostserious concern may be recognition of the inflation problem.Beyond the initial correction of subsidies there is the broaderissue of the risk of a serious inflation. This article looksat the problem of high inflation in developing countries inEurope and Latin America and draws lessons from historical experience.It analyzes the dynamics of the interaction among deficit finance,institutional innovation in financial markets, dollarization,and the shortening of wage contracts in high-inflation situations.When stabilization is undertaken, there is neither immediate,spontaneous resumption of longer adjustment periods for wagesand prices nor instant increase of real money demand to noninflationarylevels. Incomes policy—freezing exchange rates, wages,and prices—is advocated as an effective supplement tothe inevitable budget cut to make up for institutional inertiaand facilitate the start of the stabilization process.     

Inflation and the Financing of Government Expenditure: an Introductory Analysis with an Application to Turkey

This article presents a simple framework to assess the consistencyof appropriately defined fiscal deficits with other macroeconomictargets, such as inflation. It also considers the relation offiscal deficits to output growth, real exchange rate developments,and management of internal and external debt. Finally, it considersthe implications of relying on interest-bearing government debtto postpone the adjustment necessary to restore consistencywith inflation targets. It demonstrates how the intertemporalbudget constraint of the government creates a tradeoff betweencurrent and future adjustment. Real interest rates and outputgrowth rates are shown to determine the terms at which thistradeoff takes place. The usefulness of this framework is demonstratedthrough an analysis of fiscal policy options in Turkey in 1985.     

INCOMPLETE MARKETS AND COMMODITY-LINKED FINANCE IN DEVELOPING COUNTRIES

This article provides a framework for appraising new financialinstruments and evaluating the extent to which they can helpalleviate problems of incomplete credit markets and contingentclaims markets in developing countries. Although the issuesinvolved apply to any new financial instrument, we give particularattention to commodity-linked securities because many developingcountries specialize in producing a handful of primary commoditiesand are therefore exposed to substantial commodity price risks.The article looks at the supply of, demand for, and pricingof commodity-linked securities and discusses some issues thataffect their use by developing countries: their special legalstatus as sovereign debt; their feasibility (since to becometruly effective they will require liquid secondary markets);and the construction of an optimal portfolio of external debtobligations. It also discusses the potential for new financialinstruments—particularly commodity-linked securities—asa tool for risk management in developing countries.      

PRIVATE INVESTMENT AND MACROECONOMIC ADJUSTMENT:A Survey

This article reviews theories of investment behavior and examinesempirical studies of investment in developing countries. Theemphasis is on understanding the interactions among macroeconomicpolicies, structural adjustment, and private investment. Thearticle deals with the effect of exchange rate policy on investment,the relationship between public and private investment, theimportance of market imperfections and financial constraintson capital formation, and the effect of economic instabilityon irreversible investment decisions.      

ALTERNATIVE FORMS OF EXTERNAL FINANCE: A SURVEY

For many developing countries, alternative forms of externalfinance—all forms of finance that are not guaranteed byor mediated through the public sector—have become increasinglyimportant as traditional financing to the public sector hasebbed. Yet a survey of the literature reveals few recent analyticalinsights about alternative financing, which includes foreigndirect investment, project lending, portfolio investment, closed-endequity funds, private nonguaranteed debt, licensing, joint ventures,quasi-equity contracts, and other forms of private, nonrecourselending to private borrowers. The literature offers little solidguidance for distinguishing between alternative and traditionalfinancing with respect to country risk, for establishing themost appropriate and efficient incentive structures and restrictionsin the host country, or for identifying the optimal financingmodes for international firms investing in developing countries.This gap in the analytical literature has important implicationsfor policy formulation. It is not always clear whether a countryis developing incentives and establishing safeguards (for ensuringadherence to project performance requirements) that are mosteffective in attracting alternative forms of finance.      

Determinants of Consumption and Savings Behavior in Developing Countries

The determinants of savings generally and the specific effectsof government policies on savings and consumption are pivotalforces in investment and economic growth. The Hall hypothesisstates that consumption is a function of lifetime ("permanent")income, rather than income in each period independently. Changesin interest and tax rates, money supply, or government expenditurewill affect permanent income and hence consumption and savingsonly if they are unexpected and thus not already incorporatedin the estimation of permanent income. We are unable to rejectthe Hall hypothesis in tests for developing countries when weallow for varying interest rates. We do find evidence of a negativeeffect of inflation on consumption, and a positive relationshipbetween the real interest rate and consumption. The evidencefor the Hall hypothesis also suggests that Ricardian equivalencemay be valid—this is Barro's hypothesis that the effecton savings is the same whether government deficits are financedthrough taxation or debt. Our preliminary testing, however,does not support Ricardian equivalence.     

Money Market Pressure and the Determinants of Banking Crises

This article develops an index of money market pressure to identify banking crises. We define banking crises as periods in which there is excessive demand for liquidity in the money market. We begin with the theoretical foundation of this new method. With the newly defined crisis episodes, we examine the determinants of banking crises using data complied from 47 countries. We find that slowdown of real GDP, lower real interest rates, extremely high inflation, large fiscal deficits, and over-valued exchange rates tend to precede banking crises. The effects of monetary base growth on the probability of banking crises are negligible.     

Sovereign debt markets in turbulent times: Creditor discrimination and crowding-out effects

In 2007, countries in the euro zone periphery were enjoying stable growth, low deficits, and low spreads. Then the financial crisis erupted and pushed them into deep recessions, raising their deficits and debt levels. By 2010, they were facing severe debt problems. Spreads increased and, surprisingly, so did the share of the debt held by domestic creditors. Credit was reallocated from the private sector to the public sector, reducing investment and deepening the recessions even further. To account for these facts, we propose a simple model of sovereign risk in which debt can be traded in secondary markets. The model has two key ingredients: creditor discrimination and crowding-out effects. Creditor discrimination arises because, in turbulent times, sovereign debt offers a higher expected return to domestic creditors than to foreign ones. This provides incentives for domestic purchases of debt. Crowding-out effects arise because private borrowing is limited by financial frictions. This implies that domestic debt purchases displace productive investment. The model shows that these purchases reduce growth and welfare, and may lead to self-fulfilling crises. It also shows how crowding-out effects can be transmitted to other countries in the euro zone, and how they may be addressed by policies at the European level.     

2011年全球经济与市场回顾和2012年展望

2011年,受欧洲主权债务危机不断蔓延的影响,发达国家经济复苏缓慢并呈现逐步分化趋势,新兴市场国家作为全球经济复苏主引擎的作用仍然突出,但也面临着经济增长趋缓的困扰。2012年,由于欧债危机隐患未除、全球金融系统依然脆弱以及发达国家自身结构性问题远未解决,全球经济方向将面临较大不确定性。未来新兴市场经济体有望继续充当全球经济复苏的主要动力,但增速将趋于放缓。发达经济体将维持宽松的货币政策,并将迫于财政赤字压力采取财政紧缩措施,而新兴经济体预计将实施相对稳健的货币政策与较为宽松的财政政策,以应对通货膨胀和经济增速趋缓的双重压力。     

Internal capital networks as a source of MNC competitive advantage: Evidence from foreign subsidiary capital structure decisions

This paper documents multinational company (MNC) strategic advantages arising from its internal financial network. Using data from US multinational company affiliates in 62 countries, we show that MNC affiliates in countries with low credit availability, poor creditor protections, high political risks, and high inflation are found to bear high interest costs and multinational affiliate debt ratios are high in high tax countries. In addition, affiliates in countries with high (low) credit availability, a high (low) corruption index, low (high) political risks and high (low) currency depreciation are found to carry high external (parent) debt ratios. We also find that currency depreciation, credit availability, and location in common law countries are negatively associated with the use of parent (relative to external) debt. Thus, our findings suggest that affiliates substitute external debt with parent debt using internal capital markets to overcome weak external financial markets and institutional environments. This is important evidence of the strategic competitive advantage based on financial networks enjoyed by MNCs.     

MACROECONOMIC ADJUSTMENT IN DEVELOPING COUNTRIES

The short-run adjustment problem in developing countries involvesboth the improvement of the current account and the reductionof inflation. In both cases, the usual reason for adjustmentis shown to be the fiscal deficit. The article distinguishesprimary adjustment costs, which are inevitable, from secondarycosts, which result, for example, from failure to devalue orfrom real wage rigidity. The article then analyzes the effectsof expenditure reduction and currency devaluation on varioussectors of the economy. Reducing inflation involves both aninflation tax replacement and a price adjustment problem, and"heterodox" policies designed to deal with the latter are discussed.If the fiscal deficit cannot be reduced, the article argues,improving the current account may be at the cost of increasinginflation and likewise reducing inflation may be at the costof worsening the current account.

Fiscal Requirements for Dynamic and Real Determinacies in Economies with Private Provision of Liquidity: A Monetarist Assessment

We study the impact of fiscal policies on the inherent links between inflation, unemployment, and asset prices in an environment where firms provide liquidity and the central bank follows a constant money growth rate rule. Firms, other than hiring workers, also supply private assets that are not only useful as a store of value but also as collateral. When firms are not taxed and public debt is scarce, the economy is non-Ricardian so that real indeterminacies can be observed. Moreover, labor market characteristics do not affect the demand for government liabilities. However, when agents face public and private asset scarcity, labor market conditions then impact asset prices and inflation. We further show that irrespective of the type of asset scarcity agents face, when firms are taxed non-ad valorem, not only the level of tax revenues but also its composition matter for real allocations. Moreover, we show that labor market conditions directly affect the dynamics of all government liabilities and inflation.     

Return and Maturity Relationships for Treasury Auctions: Evidence from Turkey

The relationship between the interest rate and the maturity of newly issued bonds provides information on the debt dynamics of an economy as well as on the sustainability of its debt. Such information is crucial especially for countries that have debt‐rollover concerns due to financial stress and/or macroeconomic instability. This study investigates the relationship between treasury auction maturity, which also dictates the debt maturity, and auction interest rates. When the Turkish treasury auction data from 1988 to 2004 are analysed, a reciprocal linkage between auction interest rates and maturities can be observed, especially for the 1995–2000 period, when there were chronic high inflation, high political uncertainty, high public deficits and unsuccessful attempts at stabilisation. This suggests that under an adverse shock, the Treasury decreases the auction maturity in order not to increase interest rates too much. A change in this reciprocal relationship is also reported for the post‐2001 era, which is characterised by decreasing inflation, higher political stability, lower public deficits and successful stabilisation attempts.     

The Strange and Futile World of Trade Wars

U.S. President Donald Trump has a misguided, mercantilist view of international trade. He believes that an external (or “trade”) deficit is a “problem,” and that this deficit is caused by foreigners engaging in unfair trade practices. Accordingly, the president and his followers feel that the U.S. is being—and has long been—victimized by foreigners. The reality, however, is that the negative external balance in the U.S. is neither a “problem” nor is it attributable to foreigners engaging in nefarious activities. The U.S.'s negative external balance, which the country has registered every year since 1975, is “made in the USA.” External balances are always and everywhere homegrown; they are the reflection and the result of the relationship between domestic savings and domestic investment. And it is the gap between a country's savings and domestic investment that is the fundamental driver and determinant of its external balance. Specifically, the current account balance, or “trade deficit,” is the sum of the private savings‐investment gap and the public savings‐investment gap, or what is known as the “fiscal balance.” From 1972 until the end of 2018, for example, the cumulative private sector savings‐investment gap in the U.S. was a positive $12.8 trillion; that is, U.S. companies and individuals collectively saved—that is, earned and retained—some $12.8 trillion more than they consumed and invested domestically. But this positive balance was completely overshadowed by the cumulative negative government gap—or cumulative fiscal deficits—of $24.2 trillion during this 47‐year period. And thus the U.S. as a whole experienced a savings‐investment gap of negative $11.4 trillion that is entirely attributable to the country's fiscal deficits. What's more, the fact that the U.S. recorded a cumulative current account deficit of $11.5 trillion during this period confirms that the U.S. external deficits simply mirror what is happening in the U.S. domestic economy, just as the savings‐investment identity suggests. And, of course, the savings‐investment identity holds true for all countries, even those with significant external surpluses. Japan and China have both long experienced savings surpluses, and both have run current account surpluses that have mirrored their positive savings‐investment gaps. If the U.S. mercantilists understood what causes trade and current account deficits, they would direct their ire at profligate government spending rather than at foreigners. But they don't understand. And the leader of the mercantilists, President Trump, is flying blind and presiding over ever‐expanding fiscal deficits—which will only ensure that the current account deficits not just continue, but get bigger.     

Public sector layoffs, severance pay, and inflation in the small open economy

Because severance pay is worth 2–5 years of wages in many LDCs, public sector layoffs increase the fiscal deficit in the short run. Nevertheless, generous severance pay is not as serious a macroeconomic problem as generally thought. In the case where the fiscal deficit is financed by printing money, inflation is continuously lower under plausible conditions. When the government can borrow in world capital markets and layoffs reduce the present-value wage bill, there exists a sequence of bond sales and subsequent redemptions that guarantees continuously lower inflation. This result does not hold, however, if the reform lacks credibility.     

Special Exchange Rates for Capital Account Transactions

The governments of developing countries are constrained in theeffective implementation of domestic policy by the interlinkagesof national and international financial markets. Domestic macroeconomicconditions are influenced by the interaction of national andworld interest rates and prices, and through the impact of realexchange rates on employment. The domestic responses to changesin these factors are often strong and rapid. In an attempt tosever these ties, governments have adopted dual exchange ratesystems in which capital account transactions are conductedat a depreciated exchange rate while an otherwise overvaluedrate is maintained for commercial trade. This article suggeststhat dual rates can indeed be used successfully as a strictlytransitory policy to offset sudden shocks in capital markets.The article develops models which indicate why these dual systemsare able to prevent inflationary or recessionary pressures causedby a misaligned exchange rate in the short term. While freecapital account rates can cut the flow of capital flight, however,a dual rate system cannot prevent a possibly equivalent lossof foreign reserves that will ultimately result because of theimpact of the overvaluation of the commercial rate on the tradebalance. In the longer term, a dual rate system with a misalignedcommercial rate exacerbates the government's deficit; ultimately,real wages must be cut and real interest rates raised to generatesufficient foreign exchange to finance the external debt. Thusa dual rate works well if the commercial rate is maintainedclose to the equilibrium level.     

COMMODITY EXPORT BOOMS IN DEVELOPING COUNTRIES

This article surveys the experiences of commodity-exportingcountries faced with resource discoveries and widely fluctuatingworld prices. Favorable developments of the commodity exportmarket often prove to be a mixed blessing, as poor boom managementleads to major internal and external economic imbalances. Manydeveloping countries overconsume during boom periods. More oftenthan not, the unsustainable increases in spending are initiatedby the public sector. When the boom ends, tardiness in decreasinggovernment spending and in increasing revenues from nonboomingsectors creates fiscal deficits and monetary control problems. In the 1970s many booming economies allowed regulated pricestructures, and particularly exchange rates, to deviate substantiallyfrom free market levels, discouraging efficient resource allocationand greatly compounding the problems of adjustment to subsequentdrops in export prices. Countries that managed booms well weretypically those that (a) did not allow fiscal variables, exchangerates, agricultural producer prices, and wages to get badlyout of line, (b) avoided indulging in wasteful and inefficientinvestment or investment that involved burdensome recurrentcosts, (c) limited increases in government spending to levelsconsistent with long–term trends in revenue collection,and (d) maintained prudent external borrowing and foreign exchangereserve policies.
