Time–frequency relationship between US output with commodity and asset prices

Commodity and asset prices have a well-documented effect on economic growth as manifested through various channels. At the same time, the business cycle influences the commodity and asset prices. Whereas empirical evidence on the effect of commodity and asset prices on the long-run economic growth is ambiguous, most of the previous researches highlight a positive correlation in the short run. The aim of this article is to disentangle the short- and long-run co-movements between US historical business cycles and commodity and asset prices over the period 1859–2013. For this purpose, we use a time–frequency approach and we test the historical influence of oil, gold, housing and stock prices over the output growth. In contrast to other studies, we control for the effect of other prices and monetary conditions, using the wavelet partial coherency. In line with the previous works, we discover that co-movements between economic growth and commodity and assets prices manifest especially in the short run. We also find that stock returns and housing prices have a more powerful effect on the US economic growth rate than the oil and gold prices. The long-run co-movements are documented especially around the World War II. Finally, when controlling for the influence of the interest rate, inflation and other commodity and asset prices, co-movements become weaker in the short run. In general, the oil and housing prices lead the GDP growth, the US output leads the gold prices, while there is no clear causality direction between business cycle and stock prices.     

Natural Resource Booms and Inequality: Theory and Evidence*

We develop a theory, in the context of a two‐sector growth model in which learning‐by‐doing drives growth, to explain the time path of income inequality following natural resource booms in resource‐rich countries. Under the condition of a relatively unskilled labor intensive non‐traded sector, inequality falls immediately after a boom, and then increases steadily over time until the initial impact of the boom disappears. Using data for 90 countries between 1965 and 1999, we find evidence in support of the theory, especially for oil and mineral booms. We also find that uncertainty about future commodity prices increases long‐run inequality.     

Distributional Consequences of Commodity Price Shocks: Australia Over A Century

This paper studies the distributional impact of commodity price shocks over the short and the very long run. Using a GARCH model, we find that Australia experienced more volatility than many commodity exporting developing countries over the periods 1865–1940 and 1960–2008. We conduct cointegration tests to assess the commodity price shock inequality nexus. A single equation error correction model suggests that commodity price shocks increase the income share of the top 1, 0.05, and 0.01 percent in the short run. The very top end of the income distribution benefits from commodity booms disproportionately more than the rest of the society. The short run effect is mainly driven by wool and mining and not agricultural commodities. A sustained increase in the price of renewables (wool) reduces inequality whereas the same for non‐renewable resources (minerals) increases inequality. We expect that the initial distribution of land and mineral resources explains the asymmetric result.     

The Economic Effects of North Sea Oil on the Manufacturing Sector

This paper analyses the economic effects of the oil and gas sector (energy booms) on manufacturing output in two energy producing countries: Norway and the UK. In particular, I investigate whether there is evidence of a 'Dutch disease', that is whether energy booms have had adverse effects on manufactures. In addition to energy booms, three other types of structural disturbances are identified; demand, supply and oil price shocks. The different disturbances are identified by imposing dynamic restrictions on a vector autoregressive model. Overall, there is only weak evidence of a Dutch disease in the UK, whereas manufacturing output in Norway has actually benefited from energy discoveries and higher oil prices     

Macroeconomic volatility and anti-refugee violence in developing countries: Evidence from commodity price shocks

I investigate the effect of macroeconomic (output) volatility on anti-refugee violence in developing countries. Opportunity cost, rapacity, and state capacity theories predict ambiguous effects. For causal inference I leverage output volatility caused by plausibly exogenous commodity price shocks. I find that adverse commodity price shocks increase both violence of natives against refugees and violence between refugees. My results suggest that anti-refugee violence increases during recessions and decreases during economic booms.     

Cyclical fiscal rules for oil-exporting countries

Budget-balance tax-gap rules are preferred to other fiscal policy rules to stabilize the macroeconomic volatility and welfare in oil-exporting countries. The output-inflation trade-off is of particular concern for oil exporters relative to non-oil commodity exporters due to the pass through of oil prices into headline inflation which warrants fiscal reaction to crude oil revenue. This result is robust to several instruments satisfying the rule but with reduced efficiency for those instruments that impact potential output such as government investment and capital taxes. These rules are desirable for fixed exchange rate regimes but are unable to achieve the same degree of stability as when coordinated with inflation-targeting monetary policy. Even under optimal inflation-targeting regimes, the adoption of budget-balance tax-gap rules can produce reductions in macroeconomic volatility and welfare gains.     

China’s competition and the export price strategies of developed countries

This paper analyzes the impact of Chinese competition on developed countries’ export prices. The empirical application is on Italy, one of the main European manufacturing exporters with exports at high risk of competition from China. Our results show that, following China’s entry into the WTO, the price strategies of Italian firms has been affected. While in general the increasing Chinese export competition resulted in an upgrading of products exported, the impact has been different according to the sector and technological level. The incentives to upgrade have been stronger for low technology sectors, where competition is tougher and varieties of products sold lower. To highlight quality differentials, and isolate the effects on the different segments of the distribution of Italy’s export prices, we run quantile regressions. We find that are mainly those products sold at low prices to face a strong pressure to upgrade.     

Economic Uncertainty,Monetary Uncertainty,and the Demand for Money: Evidence From Asian Countries

In 1984 Nobel Lauriat Milton Friedman claimed that the decline in velocity of money or an increase in the demand for money was due to volatility of money supply. Another study argued that if monetary volatility could impact the demand for money, so can output volatility (as a measure of economic uncertainty). Both measures of uncertainty can cause people to reallocate their assets between cash and real assets that are less risky. If public become more cautious about the future, they will hold more cash today. However, if they chose to hedge against uncertain prices, they may hold more real assets and less cash. These two hypotheses are tested for Asian countries using bounds testing approach. While both measures are found to have short‐run significant effects on the demand for money in almost all countries, the short‐run effects last into the long run in half of the countries. Furthermore, we find positive and negative effects of both measures which are in line with previous research related to a few developed countries.     

New trade theory,non-price competitiveness and export performance

This paper develops a demand function for Greece's exports of manufactures according to New Trade Theory. Non-price competitiveness plays a vital role in explaining export performance and failure to include it in the export equation may lead to mis-specification error. Foreign income has a moderately high effect on exports in the long run and no effect in the short run. Exports are also sensitive to domestic and competitors' prices in the long run, but cost and price competitiveness elasticities are close to one, indicating that Greek exporters have some ability to compete on the basis of prices.     

Global Liquidity and Commodity Prices

While monetary easing and increasing participation of financial institutions in commodity trading have enhanced the financialization of commodity markets, this paper investigates empirically whether the impact of global liquidity on commodity prices has grown since the crisis. For each commodity group, this paper uses a structural vector autoregression (SVAR) model to address the short‐run relationship between global liquidity and commodity prices. The key finding is that the effect of global liquidity on commodity prices becomes more salient since the global financial crisis. This paper also suggests a price‐based liquidity indicator has a greater explanatory power for the commodity price dynamics than monetary aggregates.     

A model of commodity prices after Sir Arthur Lewis

We develop an idea from Arthur Lewis' paper on unlimited supplies of labor to model the long-run behavior of the prices of primary commodity produced by poor countries. Commodity supply is assumed infinitely elastic in the long run, and the rate of growth of supply responds to the excess of the current price over the long-run supply price. Demand is linked to the level of world income and to the price of the commodity, so that price is stationary around its supply price, and commodity supply and world income are cointegrated. The model is fitted to long-run historical data.     

中国改革历程中的产出和价格波动:货币所扮演的角色

中国经济正在其改革历程中经历着经济增长和通货膨胀的周期性波动.关于货币在这些波动中所起的作用,经济学家有着不同的观点.该文运用基于交易方程式的结构化 VEC 模型,对这些观点进行了探讨.我们发现,在长期,货币对产出和价格的变化做出适应性调整,而并非这些变化的原因.而在短期,价格变动要归因于那些对货币和价格有持久影响而对真实产出没有持久影响的冲击.这些冲击对多数的货币波动负责,并且强烈地影响产出.     

ESTIMATING IMPORT AND EXPORT DEMAND ELASTICITIES FOR MAURITIUS AND SOUTH AFRICA

In this paper, we re‐estimate the import and the export demand functions for Mauritius and South Africa using time series data. We use the bounds tests for cointegration and find evidence of a long‐run relationship between import demand, income and prices for both countries. Our long run elasticities reveal that domestic income and relative prices have significant effects on the import demand for both countries, with income being the most important determinant. Furthermore, we find that while South Africa's export demand is not responsive to relative prices or income; for Mauritius income is statistically significant.     

Global Determinants of the Gold Price: A Multivariate Cointegration Analysis

The present paper follows publications which have investigated the influence of global liquidity developments on commodity prices and asset price indices. It contributes to the literature by analyzing how global developments in money, output, and inflation can be related to developments in gold prices in a long‐run perspective. Applying a multivariate cointegration (CVAR) analysis, this study investigates long‐run relationships between these variables. The results suggest a significant influence of excess global liquidity on real gold prices and a co‐movement of real gold prices and global inflation.

Cointegration relationships and hedonic pricing of differentiated commodities: an application to price dynamics in the US dairy sector

This study investigates the implications of hedonic pricing for price dynamics of differentiated commodities. A conceptual model of hedonic pricing is developed under a Leontief technology, showing how commodity prices reflect the underlying value of their components. Implications for the existence of cointegration relationships among commodity prices are derived. An application to the pricing and dynamics of selected US dairy commodities is presented. It provides evidence on the role of component valuation in the dynamics of dairy commodity prices in the short run as well as in the long run. Distinguishing between market regime and government regime (when the government price support is active), the analysis finds significant differences in dairy price dynamics between the two regimes.     

Resource Price,Macroeconomic Distortions,and Public Outlay: Evidence from Oil-Exporting Countries

This study examines the repercussions of oil price and macroeconomic distortions on government expenditure in 15 oil-exporting countries. Adapting the Pooled Mean Group analytical approach, the long-run findings are indicative of a blend of the Dutch disease and rent-seeking hypothesis of the resource curse theory in oil-exporting countries. These effects crucially impact on the poor growth of the real sector in these countries, needed for diversification of their revenue base. Furthermore, both resource curses account for one of the reasons why fiscal deficits in oil-exporting countries have been on the rise. The country short-run coefficient for the balance of payment, economic growth, and exchange rate also supports the Dutch disease and rent-seeking hypothesis mix found in the long run. Also, the significant negative impact of oil rents in most countries shows that oil-exporting countries have been making attempts at diversifying their income sources; this is because proceeds from oil cannot be relied upon to adequately finance growing government expenditure, due to the volatile nature of oil prices, thus suggesting also that the volatility hypothesis is valid for most oil-exporting countries in the short run.     

Foreign investments in real estate,economic growth and property prices: evidence from OECD countries

The last two decades have witnessed a growth in foreign direct investments (FDI) in the real estate sector in most of the Organization for Economic Co-Operation and Development (OECD) countries. It is argued that FDI in the real estate sector may improve economic growth in recipient economies. On the other hand, property prices have increased considerably in OECD countries in recent years and some argue that FDI in real estate is one of the driving forces of high property prices in these countries. The purpose of this study is to analyze the interrelationship between FDI in the real estate sector, economic growth, and property prices while controlling for interest rate and inflation. We use observations from a set of OECD countries for the period between 1995 and 2008. The dynamic interrelationship is analyzed by applying a panel cointegration technique. Our empirical results show that FDI in real estate do not cause property price appreciations and also do not contribute to economic growth in OECD countries in the short run and the long run.     

Financial Development and Economic Activity in Advanced and Developing Open Economies: Evidence from Panel Cointegration

This study considers the effects of financial development on output in a panel cointegration framework, focusing on the implications of trade and financial openness. Our analysis indicates that after controlling for cross‐sectional dependence, the typical relationship between finance and output does not hold in the long run. This relationship, however, is re‐established once we account for economic openness. While trade openness emerges as more important for developing countries, financial openness is more important for advanced economies. In the long run, causality runs from financial development to output in the advanced economies, while in developing economies causality is bidirectional. There is no short‐run causality between financial development and output, however.     

Chinese resource demand and the natural resource supplier

This article provides empirical evidence on the effects of Chinese resource demand on the resource-rich natural resource supplier using the example of Australia. A structural VAR model is used to examine the effects of Chinese resource demand, commodity prices and foreign output on the macroeconomy with a formally specified mining and resource export sector. The key findings of the article are that shocks to Chinese demand and commodity prices result in a sustained increase in commodity prices and mining investment and a positive impact on the resource sector. However, these shocks eventually lead to lower real domestic output with factors of production moving out of the nonresource sectors and into the resource sector, resulting in a fall in nonresource sector output which is not fully offset by the rise in resource sector output. The results also indicate some market power by the natural resource supplier.
