Explaining Italy's economic growth: A balance-of-payments approach with internal and external imbalances and non-neutral relative prices

Thirlwall's Law (Thirlwall, 1979) considers that growth can be constrained by the balance-of-payments when the current account is in permanent deficit. The law focuses on external imbalances as impediments to growth and does not consider the case where internal imbalances emerging from budget deficits or public debt can also constrain growth. The recent European public debt crisis of peripheral countries (including Italy) shows that when internal imbalances are out of control they can constrain growth and domestic demand in a severe way. Recently, Soukiazis et al. (2013) developed a model – henceforth the SCA model – that takes into account both internal and external imbalances and where relative prices are not neutral in the pace of economic growth. The SCA model proved to be accurate in explaining economic growth in Portugal. The aim of the present paper is to apply the SCA model to Italy and check its precision for explaining the growth path in this country. Italy is an interesting case study of a larger economy with a lack of growth in the last decade facing serious internal imbalances caused by high deficit and public debt. Our empirical analysis shows that Italy grew at a slower rate than its potential capacity due to supply constraints. Policies designed at increasing external competitiveness and lowering the costs of financing the economy are shown to be effective strategies to achieve higher growth.     

The Greek economy under the twin-deficit pressure: a demand orientated growth approach

This paper uses an alternative growth approach in line with Thirlwall’s model in order to predict economic growth in Greece taking into account internal and external imbalances caused by public deficit/debt and lack of trade competitiveness. It is shown that the simple Thirlwall’s Law (given by the product of the ratio of the income elasticities of demand for exports and imports, and the growth of foreign demand) over-predicts real growth in Greece while the more complete extended model, makes a closer prediction which is consistent with the high deficit/debt and current account deficit experienced in this country. The simulation approach shows that the most efficient policy to attain higher growth is to reduce external imbalances while policies to reduce internal imbalances are low growth enhancing.     

A 'Generalised' Version of the Balance-of-Payments Growth Model: An application to neighbouring regions

This paper applies a 'generalised' version of Thirlwall's balance-of-payments (BOP) constrained growth model by testing for long-run relationships between the output growth rates of OECD countries and two neighbouring regions; South Africa (SA) and the rest of the Southern African Development Community (RSADC). The empirical results find strong support for the 'generalised' BOP growth model, which stresses the mutual interdependence of the world economy where one country's growth rate depends on others'. Although the policy implications are not mutually exclusive, they may be viewed from the individual perspectives of SA and RSADC. SA is only BOP constrained with respect to OECD. The message to SA's policy makers is that faster growth rates may be the result of an improvement in the structural demand features of its exports to OECD. RSADC is only BOP constrained with respect to SA. Growth-promoting policies in SA may have a high and positive impact on the whole SADC region. Policy-makers in RSADC, however, are advised to reduce their dependence on SA by improving the structural demand features of their exports to OECD.     

‘Thirlwall's Law’ and balance of payments constrained growth: more on the debate

The various criticisms that have levelled against Thirlwall's Law by McGregor and Swales are examined. It is shown that their arguments are untenable. The relationship between the necolassical law of one price and Thirlwall's Law is clarified. Thirlwall's Law is not overwhelmingly rejected by the evidence as McGregor and Swales assert. Their suppression of the influence of the price term on the estimates used in the test proposed by McCombie is inappropriate. Their regression analyis is also mid-specified and a preferable specification provides no support for their conclusions. They repeatedly argue that Thirlwall's modele cannot account for changes in market shares and the that the estimated income elasticities of demand for exports and imports cannot capture the effects of non-price competition. This was shown to be erroneous by McCombie and the reasons advanced are further elaborated. McGregor and Swales provide another interpretation of the relationship between Thirlwll's Law and the Harrod foreign trade multiplier, But their criticism of McCombie is unwarranted. The methodology of McGregor and Swales seems to be one of ‘naive falsificationism’.     

Balance of Payments Constrained Growth and Developing Countries: An examination of Thirlwall's hypothesis

Thirlwall's hypothesis of balance of payments constrained growth has been widely tested for developed countries, but much less for developing countries. Further, previous tests have used dated estimates derived using non-robust econometric techniques. After discussing the conditions under which Thirlwall's hypothesis would be valid and the econometric issues involved, this study reports error correction estimates of import and export demand functions for a large sample of developing countries. Deriving the long run income elasticities of demand from these functions, the study reports tests for different specifications of Thirlwall's hypothesis on this sample and finds some support for it.     

Current Account Imbalances or Too Much Bank Debt as the Main Driver of Gross Capital Inflows? Spain During the Great Financial Crisis

Abstract:

In contrast to the widespread view which posits that large current account deficits and net international debt were at the epicenter of the crisis in the Euro Zone, with diverging competitiveness playing a central role, this article points to the huge volume of bank credit that banks refinanced in international markets.

With a focus on the Spanish economy, we ground our view in an analysis linking gross—not net—capital flows, bank credit, and gross external debt, which provides more adequate information about a country’s international financing patterns and its external exposure.

The main conclusion of this article is that the principle driver of gross external debt in Spain was bank credit, with accumulated current account deficits accounting for less than 50 percent of gross external debt. Other consequences in keeping with this view are: the measures of economic policy required to sort out current account imbalances—particularly wage devaluation to improve competitiveness—may do more harm than good and they do not prevent the problem of too much bank credit from occurring again, and the residence of debt holders in the Euro Zone crisis is relevant for the understanding of the crisis as the result of a power imbalance     

The Euroland crisis and Germany’s euro trilemma

This paper investigates the causes behind the Euroland crisis, particularly Germany’s role in it. It is argued that the crisis is not primarily a ‘sovereign debt crisis’, but rather a (twin) banking and balance of payments crisis. Intra-area competitiveness and current account imbalances, and the corresponding debt flows that such imbalances give rise to, are at the heart of the matter, and they ultimately go back to competitive wage restraint on Germany’s part since the late 1990s. Germany broke the golden rule of a monetary union: commitment to a common inflation rate. As a result, the country faces a trilemma of its own making and must make a critical choice, since it cannot have it all – perpetual export surpluses, a no transfer/no bailout monetary union, and a ‘clean,’ independent central bank. Misdiagnosis and the wrongly prescribed medication of austerity have made the situation worse by adding a growth crisis to the potpourri of internal stresses that threaten the euro’s survival. The crisis in Euroland poses a global ‘too big to fail’ threat, and presents a moral hazard of perhaps unprecedented scale to the global community.     

Estimating the effect of the EMU on current account balances: A synthetic control approach

The European sovereign debt crisis wrought major political and economic damage on the European Monetary Union (EMU). This led to a reassessment of the pre-crisis period of economic growth and stability in the EMU, shifting attention to the macroeconomic imbalances that emerged between member states, especially those in current account balances. This paper uses macroeconomic data on OECD economies and a new statistical approach for causal inference in observational studies—the synthetic control method—to estimate the effect of the EMU on the current account balances of individual member states. This ‘counterfactuals’ approach provides strong evidence that the introduction of the EMU was responsible for the divergence in current account balances among member states in the run-up to the euro crisis. The results suggest that the EMU effect operated through multiple channels and that fundamental changes to the institutional framework of the EMU may be required to safeguard the currency union against a reemergence of dangerous external imbalances in the future.

Endogenous current account balances in a world CGE model with international financial assets

This paper presents an applied computable general equilibrium world model with financial assets and endogenous current account, and capital and financial account balances. The capital and financial account equilibrium conditions, rather than exogenous rules, constrain the current account balance. International capital flows which balance the current account are constrained by supply-and-demand equilibrium conditions on the market for international debt securities, under portfolio managers' optimizing behavior. The asset–liability structure of the financial portfolio is endogenous, and it is possible for a country-agent to have negative net financial assets. In simulations, the interaction of portfolio choices with trade supply and demand behavior leads to endogenous sign reversals in some current account balances, and it results in a different allocation of investment among regions, compared to a model with exogenously determined current account balances. In the reference scenario, this allocation generates growth that is about the same globally, but differently distributed between regions.     

Can interest rate spreads stabilize the euro area?

Since the onset of the financial crisis significant interest rate spreads have arisen between euro area countries, both for public and private debt. We check whether these spreads could be made to work towards the goal of providing more stability to the euro area. In particular, we focus on reducing the imbalances that arose between the core and peripheral members of the euro area in the first decade of its existence. The idea is that stable positive spreads in peripheral countries could have decreased domestic demand, preventing the boom–bust cycles that plagued these economies. They could also prevent such developments in the future. We construct a panel model for euro area countries and estimate the relationship between real interest rates and the current account balance. Next, we use the estimated parameters to perform simulations. We find that spreads on real interest rates of 0.6–5.5 percentage points would have been necessary to stabilize external positions of the four peripheral euro area member countries.     

Exchange Rate Management and the External Debt Burden: The Case of the Philippines

The paper develops a simple macroeconomic model which is then estimated for the Philippines. Econometric evidence shows that Philippines monetary authorities have been reluctant to allow a real devaluation, because of a large public external debt and for the fear of fueling inflation. Simulations show that, while an overvalued exchange rate may bring some benefits in the form of lower inflation and improved budgetary performance, its current account costs may be significant. Brady-like deals can reduce fiscal imbalances, limit the sensitivity of fiscal aggregates to the exchange rate, and increase the benefits of a more aggressive exchange rate policy.     

Balance-of-payments constrained growth model for the Turkish economy

Economists have investigated the relationship between output and export in order to explain economic growth for long years. Numerous studies have found very close correspondence between the growth of output and export. It is commonly known that Thirlwall's papers indicate very tight relationship between the growth of output and the ratio of the growth of exports to the income elasticity of demand for imports. This paper aims to apply Thirlwall's balance-of-payments-constrained (BPC) model for the Turkish economy for 1968–2011 period. This research also evaluates the procedures of testing Thirlwall's principle by estimation of the income elasticity of demand for imports using the test of stationarity and cointegration methods. The findings are in accordance with the Harrod–Thirlwall growth model. The test results of Johansen cointegration procedure and the comments on these results are presented as well.     

Distributive cycles and endogenous technical change in a BoPC growth model

Our purpose in this paper is to expand Goodwin's (1967) distributive cycle model to an open economy framework in a way that incorporates the balance-of-payments constraint on growth. We do so by allowing technical change to be endogenous to the cyclical dynamics of the system and by adopting an independent investment function. We show that a Hopf-Bifurcation analysis establishes the possibility of persistent and bounded cyclical paths both for a 3D and a 4D extension of the model. Some numerical simulations are performed based on the analytical models developed. Motivational empirical evidence is also provided for Thirlwall's law using a sample of 16 OECD countries.     

Euro Crises and Euro Scams: Trade not Debt and Deficits Tell the Tale

The euro crisis has been typically presented as excessive fiscal deficits leading to the accumulation of unsustainable public debts. This debt and deficit diagnosis applied most notably in Greece and Italy, but also in Portugal and Spain (the ‘PIGS’). Implicit in much of the analysis, and occasionally explicit, is the suggestion that these were not only profligate but also lazy PIGS that spent beyond their means and abandoned a commitment to international competitiveness. This article demonstrates that the German export-led growth strategy generated large trade and current account deficits throughout the eurozone in the 2000s. When the global financial crisis struck the continent in 2008, these trade-based deficits proved unsustainable. With the exception of Greece, neither public debts nor fiscal deficits represented a major problem among eurozone countries prior to 2008. The analysis leads to measures that could have avoided the crisis of sovereign debt entirely, as well as corrected the unsustainable trade balances in the euro zone. These policies were not seriously considered, with the result that in the second decade of the 21st century the future of the common currency is in doubt.     

Fundamentals and Sovereign Risk of Emerging Markets

We empirically assess the relative importance of various economic fundamentals in accounting for the sovereign credit default swap (CDS) spreads of emerging markets during 2004–2012, which encompasses the global financial crisis of 2008–2009. Inflation, state fragility, external debt and commodity terms of trade volatility were positively associated, while trade openness and a more favourable fiscal balance/GDP ratio were negatively associated with sovereign CDS spreads. Yet the relative importance of economic fundamentals in the pricing of sovereign risk varies over time. The key factors are trade openness and state fragility in the pre‐crisis period, the external debt/GDP ratio and inflation in the crisis period, and inflation and the public debt/GDP ratio in the post‐crisis period. Asian countries enjoy lower sovereign spreads than Latin American countries, and this gap widened during and after the crisis. Trade openness was the biggest factor behind Asia's lower sovereign spreads before the crisis, and inflation during and after the crisis. The results imply that external factors were paramount in pricing sovereign risk prior to the crisis, but internal factors associated with the capacity to adjust to adverse shocks gained prominence during and after the crisis.     

Financing government investment and its implications for public capital: A small open economy perspective

Expenditure reductions played a key role in many small open economies during fiscal consolidation, with large declines in public investment. This led to a reduction in public capital stock and affected the competitiveness of these economies. After the sovereign debt crisis, the governments that consider increasing investment to replenish the public capital stock have limited fiscal space and have to avoid external imbalances. We show that using budget-neutral investment spending can generate long-term benefits of higher public capital stock while at the same time limiting negative consequences for the public finances and the trade balance. The best way of financing government investment, which preserves fiscal and trade balances, and increases welfare, is by reducing other government spending. The second-best is financing investment with value-added tax. Financing with debt worsens fiscal and trade balances, while using distortionary labour taxes reduces labour supply, increases wage costs and worsens the trade deficit in the short run.     

Rebalancing the Euro Area: The Costs of Internal Devaluation

This paper investigates the economic costs of rebalancing current account positions in the Euro area by means of internal devaluation. Internal devaluation relies on wage suppression in the deficit countries. Based on an old Keynesian model we estimate a current account equation, a wage-Phillips curve and an Okun's Law equation. All estimations are carried out for a panel of twelve Euro area members. From the estimation results we calculate the output costs of reducing current account deficits. Greece, Ireland, Italy, Portugal and Spain (GIIPS) had, on average, current account deficits of 8.4% of GDP in 2007. To eliminate these current account deficits, a reduction of GPD by some 47% would be necessary. Trade imbalances can be resolved in two ways: deflationary adjustment in the deficit countries or inflationary adjustment in the surplus countries. The economic costs of deflationary adjustment to those countries are equivalent to the output loss of the Great Depression. An adjustment of the surplus countries would increase growth and it would come with higher inflation, but it would allow rebalancing without a Great Depression in parts of Europe.     

The political economy of Ecuador’s external debt default

The default of the 2012 and 2030 Global Bonds during the early stages of the Alianza PAIS government in Ecuador is best understood in the context of the social conflicts that characterized the exhaustion of neoliberalism in the country and the struggle between different fractions of capital for the direction of the process of accumulation. The restructuring of external debt and the new wave of public borrowing facilitated a boost in public spending that spurred economic growth and provided a ‘fiscal pacification’ of social unrest and political instability. The movements in public debt have also been a lever for State and geopolitical repositioning that reflects a new moment in the correlation of social forces and hegemony in the world economy. In this new scenario, however, Ecuador has not overcome the structural imbalances and contradictions that underpin its external debt problematic.     

Foreign aid,external debt and governance

This paper investigates the impact of foreign aid, external debt and governance on the economic growth by extending the Ramsey–Cass–Koopman's growth model in an open economy framework. Steady-state and short run analysis shows that external debt and foreign aid do not affect the growth rate of consumption but have level impact on consumption. Foreign aid and governance encourage the economic growth but external debt creates a burden on the economy. Both investment and saving are independent of external debt and thus the current account surplus. Foreign aid does not affect investment directly but it has a direct positive impact on the savings in the economy. Therefore, it is argued that improvements in the quality of governance will stimulate the output and consumption rapidly and it acts like a catalyst.
