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.     

The relationship between agricultural commodity prices,crude oil prices and US dollar exchange rates: a panel VAR approach and causality analysis

This study examines the relationship between crude oil prices, US dollar exchange rates and 30 selected international agricultural prices and five international fertilizer prices in a panel framework. The study uses panel VAR methods and Granger causality tests on panel data sets of agricultural commodity prices (as well as specific agricultural commodity sub-groups) and fertilizer prices with monthly observations of the period from June 1983 to June 2013. The empirical results of the present study indicate that crude oil prices as well as US dollar exchange rates affect international agricultural commodity and fertilizer prices. Furthermore, contrary to the findings of several studies in the literature, the present study supports bidirectional panel causality effects between crude oil prices and international agricultural prices as well as between US exchange rates and international agricultural prices.     

The effect of exchange rates on prices,wages, and profits: A case study of the United Kingdom in the 1990s

Abstract

During the 1990s the United Kingdom experienced large and sudden exchange rate movements that had no apparent impact on overall consumer prices. This paper shows that the stability of UK consumer prices was made possible in part by offsetting movements in the price-cost margins of foreign exporters and in part by offsetting price-cost margins in the UK distribution sector. At the same time, UK manufacturers experienced margin swings in the opposite direction, largely due to their role as exporters. Thus, sterling depreciation boosted the profits of UK manufacturers and squeezed the profits of UK distributors, while sterling appreciation had the opposite effects.     

Petrol prices,oil price rises and oil price falls: some evidence for the UK since 1972

This paper examines the relationship between retail petrol prices, excise duties and crude oil prices in the UK over the period 1973–1988. The existence of a stable relationship between the petrol price, level of excise duty and spot oil price is confirmed through use of the cointegration approach. Although the speed of reaction of petrol prices to changes in the crude price depends on whether crude prices are rising or falling, any asymmetry in the pricing response is virtually absent after an adjustment period of only four months.     

Impact of foreign prices and interest rates on canadian economy under alternative monetary and exchange rate regimes

The main objective of this paper is to analyze the impact of U.S. short- and long-term monetary policy under both flexible and managed floating systems, using the new CANDIDE Model 2.0. We have also examined the role of domestic monetary policy in the Canadian economy under both fixed and flexible exchange rate systems. The following are some of the important findings of our study:

1. Our results support the traditional view that under the fixed exchange rate regime, monetary authorities cannot successfully pursue an independent monetary policy from its trading partners — an effort to increase money supply will be almost offset by increases in the balance of payments deficit. In contrast, in the flexible exchange rate regime, monetary policy is more effective in producing an increased growth in output and employment. However the increased output growth comes at the cost of higher prices induced by increased wages and a depreciation of the Canadian dollar.
2. Our results suggest that the impact of U.S. interest rates on investment, GNE, employment, productivity, and government debt is less severe in a pure floating exchange rate regime, compared to the managed floating system. However, the impact of U.S. interest rate policy on the Canadian inflation rate is worse in the case of flexible exchange rate regime. Even though real income and inflation are less favourable in both cases, our results indicate a trade-off between output growth and inflation.
3. Our results imply that under a pure floating monetary authorities can determine the long-run rate of inflation in Canada independent of others. However, the United States and Canadian economies are interrelated during the adjustment process, even under the flexible exchange rates, through the terms of trade and the wage-price spiral channels.

     

Housing prices,stock prices and the US economy

This paper studies the relationship between housing prices, stock prices, interest rates and aggregate output in the US using monthly data from 1993 to 2014. Evidence from causality tests and a variance decomposition procedure suggest that stock prices have a much larger effect on aggregate output in the US economy than do either housing prices or interest rates. Instead, the wealth effect created by changes in stock prices has a relatively large impact on US aggregate output. Separate estimations and variance decompositions for the sample periods 1993–2001, 2002–2008 and 2009–2014 show that the impact of housing prices relative to stock prices has been waning over time.     

Real exchange rates,asset prices and terms of trade: A theoretical analysis

This paper develops a continuous-time two-country dynamic equilibrium model, in which the real exchange rates, asset prices, and terms of trade are jointly determined in the presence of nontradable goods. The model determines the relation between the financial markets and real goods markets in the world economy and their responses to various shocks under the home bias assumption. A positive domestic supply shock induces a positive return on the domestic asset markets and a deterioration of terms of trade that improves the foreign output and boosts the foreign asset markets. Demand shocks act in the opposite way. This model also analyses the impact of change in the relative price of nontradable to tradable goods on the terms of trade and asset markets. A higher productivity growth in tradable goods than in nontradable goods leads to a higher relative price of nontradable to tradable goods, which appreciates the real exchange rate, deteriorates the terms of trade, and depresses the domestic and foreign asset markets. A lower relative price of nontradable goods depreciates the real exchange rate, improves the terms of trade, and lifts both the domestic and foreign asset markets.     

Production, trade, prices, exchange rates and equilibration in large experimental economies

We study market equilibration in laboratory economies that are larger and more complex than any that have been studied experimentally to date. Complexity is derived from the fact that the economies are “international” in economic structure with multiple input, output, and foreign exchange markets in operation. The economies have twenty-one markets and due to the fact that they have roughly fifty agents, the economies are characterized by several hundred equations. In spite of the complexity and interdependence of the economy, the results demonstrate the substantial power of the general equilibrium model of perfect competition to predict the direction of movement of market-level variables. Empirical patterns in the convergence process are explored and described.     

Trade flows,relative prices,and effective exchange rates: a VAR on Ethiopian data

The dynamic response of trade flows to price and effective exchange rate changes is examined via VAR using quarerly data from Ethiopia for the period 1973(i)–1985(iv). The results show one-way Granger-causality running from prices and exchange rates to imports and exports without significant feedback. Imports and exports exhibit similar response patterns to unexpected changes in relative prices and exchange rates. The responses of imports and exports are larger and the adjustment takes longer when relative prices rather than exchange rates caused a change in international prices. In the long-run, changes in prices account for a larger percentage of the forecast error variances in imports and exports than exchange rate changes. It is shown that devaluation may have an initial adverse effect on the trade balance.     

Energy prices and exchange rates of the U.S. dollar: Further evidence from linear and nonlinear causality analysis

The causality relationships between energy prices and exchange rates have been investigated in many existing studies. Previous investigations ignore the possible nonlinear behaviors which may be caused by asymmetry, persistence or structural breaks. To fill this gap, we apply both linear and nonlinear causality tests to examine the causal relationships between energy prices and exchange rates of the U.S. dollar. Our results show that in the period before recent financial crisis, unidirectional linear causality running from petroleum prices to exchange rates and unidirectional nonlinear causality running from exchange rates to natural gas prices are revealed. In the period after the financial crisis, the bidirectional nonlinear causality relationships between petroleum prices and exchange rates can be found and there are no causality between exchange rates and natural gas prices. Moreover, we examine the source of nonlinear behaviors of causality relationships. Our evidence indicates that both volatility spillover and regime shift contribute to nonlinear causality and the explanation power of the former one is much stronger.     

The long-run convergence of exchange rates and prices in the European Union

This paper provides tests of Purchasing Power Parity (PPP) for members of the EU-27 not in the euro area, using multivariate and panel cointegration techniques, for the period since the introduction of the euro currency in 1999 until the end of 2009. The results indicate that long-run PPP holds in ten cases and that domestic prices or the nominal exchange rate is the main driver of the short-run adjustment to stationarity. These results are discussed in terms of monetary convergence in the long-run.     

US oil consumption,oil prices,and the macroeconomy

Since the oil price shock of 1973–74, researchers have waged an intense debate regarding the connection between the U.S. energy sector and national income. Studies examining the relationship between oil prices, oil consumption, and real output have produced remarkably mixed results. In particular, the two most widely cited investigations by Darby and Hamilton come to dramatically different conclusions concerning the effect of oil shocks on economic activity. To date, however, studies of this issue have been either correlation based and thus void of causality inferences, have used overly restrictive bivariate causality techniques, or covered periods that exclude major oil price disruptions. This paper analyzes a quarterly multivariate VAR model to investigate the existence and direction of causality between oil prices, oil consumption, real output, and several other key macroeconomic policy variables. Among the key findings is that oil price shocks are not a major cause of U.S. business cycles. Moreover, our findings also suggest that both oil prices and real output cause significant changes in oil consumption without feedback. These results support the contention that a systematic U.S. conservation policy would not significantly impair real economic activity.     

Dynamic linkages between exchange rates and stock prices: Evidence from East Asian markets

This study examines dynamic linkages between exchange rates and stock prices for seven East Asian countries, including Hong Kong, Japan, Korea, Malaysia, Singapore, Taiwan, and Thailand, for the period January 1988 to October 1998. Our empirical results show a significant causal relation from exchange rates to stock prices for Hong Kong, Japan, Malaysia, and Thailand before the 1997 Asian financial crisis. We also find a causal relation from the equity market to the foreign exchange market for Hong Kong, Korea, and Singapore. Further, while no country shows a significant causality from stock prices to exchange rates during the Asian crisis, a causal relation from exchange rates to stock prices is found for all countries except Malaysia. Our findings are robust with respect to various testing methods used, including Granger causality tests, a variance decomposition analysis, and an impulse response analysis. Our findings also indicate that the linkages vary across economies with respect to exchange rate regimes, the trade size, the degree of capital control, and the size of equity market.     

The comovement between exchange rates and stock prices in the Asian emerging markets

This study investigates the comovement between exchange rates and stock prices in the Asian emerging markets. The sample covers major institutional changes, such as market liberalization and financial crises, so as to examine how the short-term and long-term relations change after such events. The autoregressive distributed lag (ARDL) model proposed by Pesaran et al. (2001) is adopted, which allows us to deal with structural breaks easily, and to handle data that have integrals of different orders. Interest rates and foreign reserves are also included in the analysis to reduce potential omitted variable bias. My empirical results suggest that the comovement between exchange rates and stock prices becomes stronger during crisis periods, consistent with contagion or spillover between asset prices, when compared with tranquil periods. Furthermore, most of the spillovers during crisis periods can be attributed to the channel running from stock price shocks to the exchange rate, suggesting that governments should stimulate economic growth and stock markets to attract capital inflow, thereby preventing a currency crisis. However, the industry causality analysis shows the comovement is not stronger for export-oriented industries for all periods, such as industrials and technology industries, thus implying that comovement between exchange rates and stock prices in the Asian emerging markets is generally driven by capital account balance rather than that of trade.     

Values, prices of production and market prices: some more evidence from the Greek economy

This paper extends the empirical investigation of the relationbetween labour values and different price forms in the caseof the Greek economy. Subjecting the labour theory of valueto empirical tests with data from various countries helps inthe derivation of general conclusions regarding its empiricalvalidity and practical usefulness. Our results on the closenessof values and prices as measured by their absolute deviationand correlation, the shape of the wage–profit curves,the predictive power of labour values over market prices comparedwith other ‘value bases’, and the comparison offundamental Marxian categories when estimated in value and priceterms provide further support for the empirical strength ofthe labour theory of value.     

On the relationship between oil price and exchange rates: A wavelet analysis

We may find numerous works in the existing literature regarding the cohesion between oil prices and exchange rates, yet an exact shape of the relationship remains undefined. By restoring to wavelet analysis and using a rich database from Japan, this study contributes to the literature by investigating the said relationship within the time–frequency space. Over the time horizon, it is being established that the strength of the relationship between oil price and exchange rate keeps changing. If the Bank of Japan needs to control the exchange rate, it should give proper importance to shocks on oil prices, while formulating exchange rate policy.

Testing the hypothesis of market efficiency in the Taiwan-US forward exchange market since 1990

This article examines the applicability of the hypothesis of market efficiency in Taiwan's foreign exchange market using daily data. Instead of linear regression-based models, we consider the possibility that the true data generating process may come from two different distributions, and we employ the Markov Switching approach to analyse this. From the results of the two-state Markov Switching model, we define State 1 as the efficient state and State 2 as the inefficient one. Only the 30-day forward rate is able to differentiate between the two states. Based on the unconditional probabilities from the Markov switching model, we also find that the 30-day forward rate has a 70% probability in the efficient state, which indicates that 70% of all speculators fully extract information when predicting future spot rates, while 30% of all investors do not.     

Unanticipated money,output, and prices in the small economy

A macroeconomic model for an open economy experiencing both domestic and international monetary disturbances is given. Expectations are assumed to be rational. Particular attention is focused on the reduced form coefficients for unanticipated domestic and foreign monetary disturbances under alternative exchange rate regimes.
