Relationship between the trading behavior of three institutional investors and Taiwan Stock Index futures returns

The relations between institutional investors' behavior and futures returns are examined in this study. Evidence suggests that net trading volume by foreign investors and investment trust have forecasting power for futures returns. In addition, the study applies a time-varying parameter vector autoregressive (TVP-VAR) approach to estimate the relative effects of trading behavior by institutional investors on futures returns over time. The impact of open interest by three institutional investors is decreasing over the recent years. This implies that the value for open interest information from three major institutional investors is gradually declining in Taiwan.     

Budget deficits,short-term real interest rates and the specification of expected inflation: an empirical investigation

The purpose of this paper is to illustrate whether empirical estimates of the effects of budget deficits on short-term real interest rates are sensitive to the choice of the expected inflation variable. Survey data on expected inflation and the rational expectations method described by Mishkin (1981) are used to construct two measures of the short-term real interest rate. Results for two previous studies on this deficit-interest rate relationship are re-estimated using these measures of expected inflation and the interest rate variables. Additional results reported in this paper further indicate that empirical estimates of the interest rate effects of budget deficits are sensitive to the choice of the expected inflation variable. In addition to the choice of the inflation variable, a number of other robustness tests are included. We are able to conclude that (1) increases in budget deficits do not generally raise short-term real interest rates and (2) short-term real interest rates are not independent of the expected inflation variable.

The rate of interest is always based upon expectation, however little this may be justified by realization. Man makes his guess of the future and stakes his action upon it … Our present acts must be controlled by the future, not as it actually is, but as it appears to us through the veil of chance (Fisher, 1907, p. 213).     

Foreign interest rate shocks and exchange rate regimes in East Asia

Using a theoretical dynamic stochastic general equilibrium model and an empirical panel vector autoregression, we assess the transmission of foreign real interest rate shocks on the volatility of various key macroeconomic variables in nine small open economies in East Asia taking into account the role of exchange rate regimes. Both the theoretical and empirical findings confirm the hypothesis that flexible exchange rate may work as a shock absorber when the economy is hit by foreign real interest rate shocks. The findings suggest a clear trade-off between the volatility of real exchange rate and real output to foreign interest rate shocks, both the US and G7 real interest rates, where the responses of real output are mitigated in countries that have more flexible exchange rate regime.     

Heterogeneous capital and misintermediation

A perennial problem of financial markets is that of maturity mismatch, or misintermediation, a situation in which financial intermediaries fund long-term, illiquid loans with short-term liabilities. A previous theory concludes that misintermediation can be responsible for business cycles and yields procyclical behavior of surprises in real interest rates. This paper proposes a finite horizon structural model with the introduction of heterogeneous capital to formalize and develop that theory. An extended model with labor as well as a “harvesting” technology further investigates the impact of misintermediation on real factor prices. The model implied relationship between unanticipated changes in real interest rates and real outputs over time is examined in a subsequent empirical study, which provides preliminary evidence consistent with the hypothesis of misintermediation.     

The links between international parity conditions and Granger causality: a study of exchange rates and prices

This article provides a simple equilibrium model of a futures market. Since the futures market is a zero sum game, some firms will, in equilibrium, end up being ‘speculators’ who bet against ‘hedgers’. We show it is firms that have high initial capital and/or poor production opportunities that are the most likely candidates to bet against the hedgers. In equilibrium, these groups earn a premium in order to provide this insurance so that speculating increases value. We also provide some results that imply an inverted U shaped relationship between trading volume and the level of futures prices. Empirical evidence from the S&P futures contract provides strong empirical support for this theoretical result.     

Speculation and corn prices

It is commonly asserted that speculative trading activities are largely behind the high and volatile food commodity price behaviour since 2006. In this article, we revisit this hypothesis by investigating how different speculative measures affect our conclusion on the role of speculation. Four speculative measures are considered, including index trading activities, non-commercial net long positions, Working’s speculative index, and an excessive speculative volume index. These four measures imply different underlying hypotheses about the role of speculation on commodity price movements and encompass most of the measures used in the recent literature on the role of speculation in commodity markets. Using a structural vector autoregressive (SVAR) model, we show a mixed impact of speculative trading on corn prices depending on the measure used. While shocks to index trading activities and excess speculation as measured by Working’s T have either zero or negative impact on corn prices, a positive shock to non-commercial net positions or the Tadesse index significantly increases the price of corn. However, the magnitude of the impact is not large, at most about $0.30 per bushel in real terms. Our findings are robust to structural breaks, alternative ordering of variables, and an alternative specification of the model.     

On the relationship between energy returns and trading volume: a multifractal analysis

Forecasting and modelling commodities price movements and the activity of energy markets are of real interest to investors and policymakers, especially during turbulent times. This study investigates the volume–returns relationship for two major energy markets (oil and gas) during the recent global financial crisis. Unlike previous studies, we examine this relationship by applying an original fractal approach to intraday data, which has the advantage of accounting for further non-normality, nonstationarity, and fat-tailedness properties. Our study provides two interesting findings. First, we find a significant multifractal relationship between returns and volume in both markets and across all timescales, suggesting nonlinearity in the cross-correlation between returns and volume and rejecting the efficiency assumption. Second, the measure of multifractality in this relationship shows that the magnitude of the fluctuations during bearish and bullish trends affects the volume–return relationship differently, and that the oil market exhibits higher volatility than does the gas market.     

Utilizing financial market information in forecasting real growth,inflation and real exchange rate

In this paper we build an open economy extension of the Gordon (1962) valuation model that suggests a simple forecasting system for three macroeconomic variables; the real growth, inflation and real exchange rate. All the forecasting equations in our system utilize current financial market information in the form of dividend yields and short-term interest rate. Our empirical results indicate that these simple forms of financial market information are relevant for forecasting the time-varying underlying trends in the macroeconomic data for the U.K., Eurozone and Japan, when treating the U.S. as the world market.     

The role of financial speculation in the energy future markets: A new time-varying coefficient approach

To study whether speculating behavior plays an important role in oil futures markets, this paper proposes a time-varying coefficient version of the model of Llorente, Michaely, Saar, and Wang (2002) and estimates the effect of the speculating behavior using a sieve maximum likelihood estimation method. Using the time-varying coefficient model and the data of crude oil and heating oil futures markets, we find that neither the speculative motive nor the hedging motive dominates the markets over the whole sample period. However, we find that one of the two motives dominates the markets over some subsample periods. More importantly, speculation dominates in both the crude oil and heating oil futures markets around 2008. These empirical findings support the argument that the speculating behavior significantly affected the sharp rise in the price of crude oil in 2008.     

Government‐spending multipliers and the zero lower bound in an open economy

This paper assesses the size of the government‐spending multiplier in an open economy when the zero lower bound (ZLB) on the nominal interest rate is binding. In a theoretical framework, in a closed economy, other authors have shown that when the nominal interest rate is binding the government‐spending multiplier can be very large (close to four). Their theory helps illuminate the government‐spending multiplier in the ZLB, but it is difficult to match that theory with the data. We argue that, in an open economy, another channel exists for the crowding‐out effect via the real exchange rate. For an open economy, the government‐spending multiplier is not large owing to the appreciation of the real exchange rate, induced by the appreciation of aggregate demand that follows the increases in government spending. To test the robustness of our open economic model, we conduct the same analysis in a corresponding closed economy model. The result from our closed economy model confirms the result obtained in the other work. Our theoretical results are consistent with the results obtained in the empirical literature, which uses the vector autoregressive method and the structural vector autoregressive approach to measure the impact of government‐spending shock on the real gross domestic product and revealed that the government‐spending multiplier tends to be lower in open economy.

Fertility choice and economic growth: Empirical evidence from the U.S.

This paper provides empirical evidence to support the proposition of Barro and Becker [1989] that fertility depends positively on the world's long-term real interest rates and negatively on real wages in an economy linked to an international capital market. The empirical evidence suggests that there is no long-run relationship among fertility choice, real wages, long-term real interest rates, and output growth in the U.S. over the period 1960–95. However, when estimating a VAR model and employing the variance decomposition analysis and the impulse response functions, the empirical results support the endogeneity of fertility choice and the proposition that real wages, long-term real interest rates, and output growth is related to changes in fertility choice. The empirical results have important policy implications and provide an explanation for the decline of fertility in Western countries mainly in the last three decades.The views expressed in this paper are those of the authors and not those of the Bank of Greece.     

小厂商与期货市场：基于分割定理的分析

Direct effects of money on aggregate demand: another look at the evidence

Now that a number of central banks are faced with short-term nominal interest rates close to or at the zero lower bound, there is a renewed interest in the long-running debate about whether or not changes in the stock of money have direct effects. In particular, do changes in money have additional effects on aggregate demand outside of those induced by changes in short-term nominal interest rates? This article revisits and reinterprets the empirical evidence based on single equation regressions which is quite mixed, with some results supporting and other results denying the existence of direct effects. We use a structural model with no direct effects of money to show that the finding of positive and statistically significant coefficients on real money growth can be misleading. The model generates data that, when used to estimate analogues of the empirical regressions, produce positive and statistically significant coefficients on real money growth, similar to those often found when using actual data. The problem is that single equation regressions leave out a set of variables, which in turn, give rise to an omitted variables bias in the estimated coefficients on real money growth. Hence, they are an unreliable guide to calibrate monetary policies, in general, including at the zero lower bound.     

Interest differentials and extreme support for uncovered interest rate parity

This paper addresses two findings from the empirical literature testing uncovered interest parity (UIP): (i) more favorable results when interest differentials (IDs) are large and (ii) instability across samples. Simulations demonstrate that explanations of the results using large IDs based on the hypothesis of a “zone of speculative inactivity” are inconsistent with empirical evidence. Furthermore, it is shown that, if agents forecast IDs based on long-run values, coefficient estimates will be unstable if rates of decay in IDs vary significantly and, for ex post UIP to hold, IDs must decay in absolute value. This is consistent with OECD country data.     

Equilibrium real interest rates and the financial cycle: Empirical evidence for Euro area member countries

We estimate the equilibrium real interest rate for nine Euro area member countries and the Euro area as a whole using quarterly data from 1995 to 2015. We expand the standard model of estimating real equilibrium interest rates to incorporate the financial cycle for the private sector. We show that adding the financial cycle indeed alters the equilibrium real interest rate estimates and, in line with previous studies, that there is a fall in the equilibrium real interest rate over time. Our results indicate that in most member countries the real rate is lower than its equilibrium level. Hence, they should not worry about secular stagnation now. This is because secular stagnation is likely to occur when real interest rates are higher than their equilibrium levels. This result can serve as a starting point for further research in this field, e.g. by adding public sector financial cycles or disentangling the roles of households, corporations and the government.     

TRADER TYPE EFFECTS ON THE VOLATILITY‐VOLUME RELATIONSHIP EVIDENCE FROM THE KOSPI 200 INDEX FUTURES MARKET

We investigate whether the trading activity generated by investors with different access to information and trading motives has positive or negative impact on index futures volatility. Surprises in non‐member institutional, individual and foreign investors' trading volume are positively associated with volatility in most of the cases. For member institutional investors, unexpected trading volume is positively related to volatility. Long‐run changes in the trading activity also affect volatility differently across trader types. Finally, allowing for time‐to‐maturity effects, surprises in open interest are associated with more volatility towards contract expiration, contrary to the negative effect we find during normal times.     

Speculative securities

Summary. A speculative security is an asset whose payoff depends in part on a random shock uncorrelated with economic fundamentals (a sunspot) about which some traders have superior information. In this paper we show that agents may find it desirable to trade such a security in spite of the fact that it is a poorer hedge against their endowment risks at the time of trade, and has an associated adverse selection cost. In the specific institutional setting of innovation of futures contracts, we show that a futures exchange may not have an incentive to introduce a speculative security even when all traders favor it.

Deliveries on Commodity Futures Contracts

Deliveries on futures contracts are widely thought to be relatively insignificant in amount; indeed sizeable deliveries are taken to indicate problems in a futures market. In fact, deliveries on five of the largest, physical delivery, futures markets in the US average approximately 10 per cent of the maximum open interest in each delivery month. Analysis also demonstrated the value of the timing and location options often provided by contract specifications. One implication is that measures of market performance like hedging effectiveness are sensitive to the imbedded options' effects on prices
