Hot Money Flows,Cycles in Primary Commodity Prices,and Financial Control in Developing Countries

Because the U.S. Federal Reserve’s monetary policy is at the center of the world dollar standard, it has a first-order impact on global financial stability. However, except during international crises, the Fed focuses on domestic American economic indicators and generally ignores collateral damage from its monetary policies on the rest of the world. Currently, ultra-low interest rates on short-term dollar assets ignite waves of hot money into Emerging Markets (EM) with convertible currencies. When each EM central bank intervenes to prevent its individual currency from appreciating, collectively they lose monetary control, inflate, and cause an upsurge in primary commodity prices internationally. These bubbles burst when some accident at the center, such as a banking crisis, causes a return of the hot money to the United States (and to other industrial countries) as commercial banks stop lending to foreign exchange speculators. World prices of primary products then collapse. African countries with exchange controls and less convertible currencies are not so attractive to currency speculators. Thus, they are less vulnerable than EM to the ebb and flow of hot money. However, African countries are more vulnerable to cycles in primary commodity prices because food is a greater proportion of their consumption, and—being less industrialized—they are more vulnerable to fluctuations in prices of their commodity exports. Supply-side shocks, such as a crop failure anywhere in the world, can affect the price of an individual commodity. But joint fluctuations in the prices of all primary products—minerals, energy, cereals, and so on—reflect monetary conditions in the world economy as determined by the ebb and flow of hot money from the United States, and increasingly from other industrial countries with near-zero interest rates.     

Oil shocks and stock volatility: new evidence via a Bayesian,graph-based VAR approach

ABSTRACT

This article examines the temporal dependence between three oil shocks and realized volatility in the stock markets of G20 countries between 1994 and 2019. By applying a novel, graphical, Bayesian VAR (BGVAR) model, we calculate unidirectional linkages of oil and stock volatility with a full and segmented sample. The results suggest an overall causality from stock volatility to oil shocks. For certain short, specific periods, the causal direction reverses. Depending on the country and the source of an oil shock, the magnitude and type of the effect can vary considerably. Specific oil-market shocks occur most often in our full sample. In a time-varying structure, oil supply shocks’ impact on stock volatility is more prominent, and net oil-importing countries’ responses to these shocks are greater than for oil-exporting countries. In addition, we find that relationship dynamics can capture market information, such as global economic growth during the 2008–2009 financial crisis.     

Financialization of food. Modelling the time-varying relation between agricultural prices and stock market dynamics

This article studies the correlation of agricultural prices with stock market dynamics. We discuss the possible role of financial and macroeconomic factors in driving this time-varying relation, with the aim of understanding what caused positive correlation between agricultural commodities and stocks in recent years. While previous works on commodity-equity correlation have focused on broad commodity indices, we study 16 agricultural prices, in order to assess patterns that are specific to agricultural commodities but also differences across markets. We show that an explanation based on a combination of financialization and financial crisis is consistent with the empirical evidence in most markets, while global demand factors don’t appear to play a significant role. The correlation between agricultural prices and stock market returns tends to increase during periods of financial turmoil. The impact of financial turmoil on the correlation gets stronger as the share of financial investors in agricultural derivatives markets rises. Our findings suggest that the influence of financial shocks on agricultural prices should decrease as global financial tensions settle down but also that, as long as agricultural markets are ‘financialized’, it might rise again when it is less needed, i.e. in the presence of new financial turmoil.     

Adding space to the international business cycle

Growth fluctuations exhibit substantial synchronization across countries, which has been viewed as reflecting a global business cycle driven by shocks with worldwide reach, or spillovers resulting from local real and/or financial linkages between countries. This paper brings these two perspectives together by analyzing international growth fluctuations in a setting that allows for both global shocks and spatial dependence. Using annual data for 117 countries over 1970–2016, the paper finds that the cross-country dependence of aggregate growth is the combined result of global shocks summarized by a latent common factor and spatial effects accruing through the growth of nearby countries – with proximity measured by bilateral trade linkages or geographic distance. The latent global factor shows a strong positive correlation with worldwide TFP growth. Countries’ exposure to global shocks is positively related to their openness to trade and the degree of commodity specialization of their economies, and negatively to their financial depth. Despite its simplicity, the empirical model fits the data well. Ignoring the cross-country dependence of growth, by omitting spatial effects or common shocks (or both) from the analysis, leads to a marked deterioration of the empirical model’s in-sample explanatory power and out-of-sample forecasting performance.     

Spillovers to low-income countries: importance of systemic emerging markets

This article documents the expanding economic linkages between low-income countries (LICs) and a narrow group of ‘Emerging Market (EM) leaders’ that have become major players in international trade and financial flows. VAR models show that these linkages have increased the share of growth volatility that can be attributed to foreign shocks in LICs. Dynamic panel models further analyse the impact of LIC trade orientation and production structure on the sensitivity to foreign shocks. The empirical results demonstrate that the elasticity of growth to trading partners’ growth is high for LICs in three out of the five regions: Asia, Latin America and the Caribbean, and Europe and Central Asia. However, for commodity-exporting LICs in Sub-Saharan Africa and the Middle East, terms of trade shocks and demand from the EM leaders are the main channels of transmission of foreign shocks     

Oil currencies in the face of oil shocks: what can be learned from time-varying specifications?

While the oil currency property is clearly established from a theoretical viewpoint, its existence is less clear-cut in the empirical literature. We investigate the reasons for this apparent puzzle by studying the time-varying nature of the relationship between real effective exchange rates of five oil exporters and the real price of oil in the aftermath of the oil price shocks of the last two decades. Accordingly, we rely on a time-varying parameter VAR specification, which allows the responses of real exchange rates to different oil price shocks to evolve over time. We find that the reason of the mixed results obtained in the empirical literature is that oil currencies follow different hybrid models in the sense that oil countries’ real exchange rates may be driven by one or several sources of oil price shocks that furthermore can vary over time. In addition to structural changes affecting oil countries, structural changes arising from the oil market itself through the various, time-varying sources of oil price shocks are found to be crucial.     

Financialization and commodity prices – an empirical analysis for coffee,cotton, wheat and oil

Commodity prices have crucial implications for developing countries. The question whether the financialization of commodity derivative markets has contributed to high and volatile commodity prices has been controversially debated. Building on limitations in the empirical literature, we estimate a multivariate Vector Autoregressive (VAR) model to assess the effect of different groups of financial investors (index investors and money managers) as well as fundamental and macroeconomic variables on the prices of coffee, cotton, wheat and oil. We find that, in contrast to index investors, money managers’ net long positions have a large statistically significant effect on commodity prices. This calls for policy interventions as commodity derivative markets may cease to perform their fundamental developmental roles.     

Trade shocks from BRIC to South Africa: A global VAR analysis

This paper studies the trade linkages between South Africa and the BRIC (Brazil, Russia, India and China) countries. We apply a global vector autoregressive model (global VAR) to investigate the degree of trade linkages and shock transmission between South Africa and the BRIC countries over the period 1995Q1–2009Q4. The model contains 32 countries and has two different estimations: the first one consists of 24 countries and one region, with the 8 countries in the euro area treated as a single economy; and the second estimation contains 20 countries and two regions, with the BRIC and the euro area countries respectively treated as a single economy. The results suggest that trade linkages exist between our focus economies; however the magnitude differs between countries. Shocks from each BRIC country are shown to have considerable impact on South African real imports and output.     

International timber markets and tropical deforestation: the evidence from prices

Some scholars suggest that global timber markets, especially those involving high value species, are a leading cause of tropical deforestation. Despite limited empirical evidence, this hypothesis rests on the assumption that global timber markets respond to a common equilibrating mechanism that provides strong enough incentives for loggers in the tropical regions of the world. This article develops a simple model and taps into a unique data set on timber prices of hardwood and softwood in leading markets to test the global timber markets hypothesis. While we find evidence of a global equilibrating mechanism with potentially significant economic incentives to affect tropical deforestation, our results do not endorse the common conjecture in the literature that timber price shocks in developed countries lead to a homogeneous response in terms of deforestation everywhere in the tropical world. Instead, they invite further development of structural global timber market models to assess the linkages between markets and the consequences of such linkages to deforestation.     

Trade Linkages and Output‐Multiplier Effects: a Structural VAR Approach with a Focus on Asia*

This paper develops a structural VAR model to measure how a shock to one country affects other countries’ GDP. It uses trade linkages to estimate the multiplier effects as a shock is transmitted through output fluctuations and introduces a new specification strategy that reduces the number of unknowns and allows cross‐country relationships to vary over time. This model is used to examine the impact of shocks to 11 Asian countries, the US, and the rest of the OECD. Impulse‐response matrices suggest that these multiplier effects are large and can transmit shocks in very different patterns than predicted from a bilateral‐trade matrix.     

Commodity prices and growth: An empirical investigation

Whereas empirical evidence on the effect of higher commodity prices on the long-run growth of commodity exporters is ambiguous, time series analyses using vector autoregressive (VAR) models have found that commodity booms raise income in the short run. In this paper we adopt panel error correction methodology to analyze global data for 1963 to 2008 to disentangle the short and long run effects of international commodity prices on output per capita. Our results show that commodity booms have unconditional positive short-term effects on output, but non-agricultural booms in countries with poor governance have adverse long-term effects which dominate the short-run gains. Our findings have important implications for non-agricultural commodity exporters with poor governance, especially in light of the recent wave of resource discoveries in low-income countries.     

LABOUR MOBILITY AND TRANS‐TASMAN CURRENCY UNION*

The prospect of a common currency for Australia and New Zealand has been canvassed by senior poli‐ticians and bureaucrats, and has been the subject of academic debate. According to Mundell (1961 ), a high degree of internal labour mobility is a desirable feature of currency unions. This study looks at the extent to which long‐term migration between Australia and New Zealand responds to output shocks. Estimated VAR models and panel Granger‐causality tests demonstrate that shocks to relative per capita output have a significant and symmetrical impact on migration flows between Australia and New Zealand, and most of the impact is felt after about one year. Separating the shocks to Australia and New Zealand shows that ‘pull’ effects are more important than ‘push’ effects. Additionally, the trajectory of the Australian economy proves particularly influential for the choice of New Zealand emigrants. Although permanent migration responds intuitively to the state of the economy in Australia and New Zealand, the level of these migration flows is low in comparison to Australian inter‐state migration; yet it is high in relation to any third country.     

Asset prices, exchange rates and the current account

This paper analyses the role of asset prices in comparison to other factors, in particular exchange rates, as a driver of the US trade balance. It employs a Bayesian structural VAR model that requires imposing only a minimum of economically meaningful sign restrictions. We find that equity market shocks and housing price shocks have been major determinants of the US current account in the past, accounting for up to 30% of the movements of the US trade balance at a horizon of 20 quarters. By contrast, shocks to the real exchange rate have been less relevant, explaining about 9% and exerting a more temporary effect on the US trade balance. Our findings suggest that large exchange rate movements may not necessarily be the key element of an adjustment of today's large current account imbalances, and that in particular relative global asset price changes could be a potent source of adjustment.     

Return and volatility transmission between oil prices and oil-exporting and oil-importing countries

This paper provides further evidence of the comovements and dynamic volatility spillovers between stock markets and oil prices for a sample of five oil-importing countries (USA, Italy, Germany, Netherland and France) and four oil-exporting countries (United Arab Emirates, Kuwait, Saudi Arabia and Venezuela). We make use of a multivariate GJR-DCC-GARCH approach developed by Glosten et al. (1993). The results show that: i) dynamic correlations do not differ for oil-importing and oil-exporting economies; ii) cross-market comovements as measured by conditional correlation coefficients increase positively in response to significant aggregate demand (precautionary demand) and oil price shocks due to global business cycle fluctuations or world turmoil; iii) oil prices exhibit positive correlation with stock markets; and iv) oil assets are not a good ‘safe haven’ for protection against stock market losses during periods of turmoil.     

ECB monetary policy and commodity prices

We assess the impact of ECB monetary policy on global aggregate and sectoral commodity prices over 2001–2019. We employ an SVAR model and separately assess periods before and after the global financial crisis. Our key results indicate that contractionary monetary policy shocks have positive effects on commodity prices during both conventional and unconventional monetary policy periods, indicating the effectiveness of unconventional monetary policy tools. The largest impact is documented on energy (fuel) and food commodities. Our results also suggest that the effect of ECB monetary policy on commodity prices transmits through the exchange rate channel, which influences European market demand.     

Do credit shocks matter? A global perspective

This paper examines the importance of credit market shocks in driving global business cycles over the period 1988:1–2009:4. We first estimate common components in various macroeconomic and financial variables of the G-7 countries. We then evaluate the role played by credit market shocks using a series of VAR models. Our findings suggest that these shocks have been influential in driving global activity during the latest global recession. Credit shocks originating in the United States also have a significant impact on the evolution of world growth during global recessions.     

Theorising the Korean State beyond Institutionalism: Class Content and Form of ‘National’ Development

Although the Korean developmental state has been heavily discussed in various disciplines and across diverse political spectrums, the statist notion that the developmental state is autonomous from and disciplines society, and is therefore effective in achieving ‘national development’, has more often been taken for granted than problematised. Statism is also pervasive in institutionalism that emphasises the linkages rather than dichotomies between state and market and in the recent discussions on the transformation of the developmental state. This article proposes an alternative conceptual framework by reformulating ‘the form critique of the state’ pioneered by Evgeny Pashukanis and further developed in the ‘German state derivation debate’ on the one hand, and ‘world system analysis’ on the other. Extending the Marxist critique of ‘commodity fetishism’ to the theorisation of the developmental state, it inquires into the origins of statism and argues that it is the uneven dynamics of capitalism as a global system that give rise to statism in the first place.     

OPTIMUM CURRENCY AREAS AND EUROPEAN MONETARY UNIFICATION

This paper examines the European experience from optimum currency areas perspective with a focus on the correlation of underlying aggregate shocks within a structural vector autoregression (VAR) framework. Appropriately identifying supply shocks, real fiscal shocks, and nominal shocks, the paper investigates the correlations of shocks and tries to evaluate the likely adjustment and other problems that may take place with the introduction of a single currency in Europe. Using data for 20 European market economies, the paper compares original members of the European Community to new members and non-members. Shocks are mostly country-specific, particularly for newer members and non-members, suggesting the importance of alternative adjustment mechanisms other than national monetary policies after the introduction of a single currency.     

Capital Mobility—Resource Gains or Losses? How,When, and for Whom?

This paper investigates which of the two types of countries—resource‐rich or resource‐poor—gains from capital market integration and capital tax competition. We develop a framework involving vertical linkages through resource‐based inputs as well as international fiscal linkages between the two types of countries. Our analysis shows that capital market integration causes capital flows from resource‐poor to resource‐rich countries and improves global production efficiency. However, such gains accrue only to resource‐poor countries, and capital mobility might even negatively affect resource‐rich countries. Furthermore, we show that resource‐rich countries can exploit the gains when taxes on capital are available.     

Withstanding financial crises: would trade partners help or hurt?

This article provides new empirical evidence on the losses of real activity caused by various financial shocks. Spillover effects due to foreign trade linkages deserve special attention. To this end, we estimate a modify auto-regressive process and a Seemingly Unrelated Regression Equations estimator is used to account for the dependency of one’s country growth on its trade-weighted partners growth. We run estimations on a set of currency collapses, banking crises and sovereign defaults in 49 advanced and developing countries from 1978 to 2011. The trade-weighted foreign demand effect mitigated the economic downturn following a banking or a sovereign debt crisis in all countries, while only the advanced ones benefited from it after a currency collapse. Trade-based spillover effects make banking crises more costly in the developing countries, in those that liberalize their financial account. It contrasts with what is observed during currency or sovereign debt crises.
