In recent years, the U.S.A. natural gas market has seen enormous changes. The expectations of abundant supply of shale gas and the slow U.S.A. economic recovery have pushed gas prices below US$ 4 MMBtu. Although shale gas is a new promising source of unconventional energy, investors face uncertain investment plans. In this study, we investigate the risk premium by comparing behaviour before and after the change point in agents risk perception. Unlike traditional empirical research on risk premium, we use the parametric, two-factor model of Schwartz and Smith (2000) to evaluate the implied risk premium term structure from futures prices traded on the New York Mercantile Exchange (NYMEX). We compare our findings with other empirical results and find that the change point lies at the beginning of the low-price regime. When we compare periods before and after the change point, we observe that the risk premium changed, not only in sign, but also in magnitude.  相似文献

The empirical results of the risk-return relationship are mixed for both mature and merging markets. In this paper, we develop a new volatility model to revisit the risk-return relation of the aggregate stock market index by extending the Realized GARCH model of Hansen et al. (2012) with the Wang and Yang (2013) framework, in which the overall risk-return relation is decomposed into a risk premium and a volatility feedback effect. An empirical analysis of three major Chinese stock indices reveals positive risk premium and negative volatility feedback effect, and those findings are stable across different markets and sub-samples. However, their relative magnitudes differ between markets and varies through time.  相似文献

This paper studies the relationships between foreign currency debt, macroeconomic volatility, and risk premia in a model of a small open emerging market economy. The external value of the local currency is counter-cyclical, so that foreign currency debt requires larger repayments than local currency debt in bad states of nature. The level of foreign currency-denominated debts, therefore, affects the volatility of aggregate demand and by extension of the exchange rate. Exchange rate volatility is in turn an important determinant of the risk premium on local currency debt. Finally, this risk premium is a major factor in the choice of local versus foreign currency for emerging market borrowers. The mutual endogeneity of foreign currency debt, risk premia, and macroeconomic volatility creates important feedback effects in the economy: small increases in international risk aversion may entail large amplification effects on macroeconomic volatility since domestic borrowers substitute towards cheaper but riskier foreign currency debt finance.  相似文献

In an incomplete market setting, we show that a pricing kernel exists, which reconciles the observed smooth real exchange rates with high domestic equity premium and low international risk sharing. The estimation results based on the US–Japanese data provide plausible estimates of the deep parameters.  相似文献

This study examines the relationship between equity market valuation and risk indicators that portend economic downswings. The indicators are implied options volatility, Treasury-Eurodollar (TED) spread and exchange rate. While implied volatility captures market risk in that it reflects the fear factor embedded in the price of an option, TED spread reflects the default risk premium that is priced into a key short-term credit instrument. Equity markets often show a tendency to reflect the incidence of these risk factors. And because they provide valuable information about the health of the economy, many have argued that equity market valuation be taken into account in the formulation of monetary policy. Results of this study not only show a statistically significant inverse relationship between the stock market and these risk factors, but also evidence of a cointegration. In a variance decomposition of the series, we find that equity valuation is a major contributor to the forecast error variances of each of the risk indicators, a finding that lends tacit support to the argument that risk indicators associated with the equity market be considered in monetary policy decisions.  相似文献

This paper shows that state-uncertainty preferences help to explain the observed exchange rate risk premium. In the framework of Lucas (1982) economy, state-uncertainty preferences amount to assuming that a given level of consumption will yield a higher level of utility the lower is the level of uncertainty perceived by consumers. Under these preferences we can distinguish between two factors driving the exchange rate risk premium: “macroeconomic risk” and “the risk associated with variation in the private agents' perception on the level of uncertainty”. Empirical evidence from three main European economies in the transition period to the euro provides empirical support for the model. The model is more successful in accounting for the observed currency risk premium than models with more standard preferences, and the general perception of risk by private agents is shown to be a more important determinant of risk premium than macroeconomic uncertainty.  相似文献

The hypothesis that the forward rate is an unbiased predictor of the future spot rate has been rejected in many empirical studies. The rejection of this hypothesis could occur because market behavior is inconsistent with rational–expectations or because there exists a risk premium. Equations describing the forward premium and the change in the exchange rate are estimated jointly, and tests of both the rational–expectations and no–risk–premium hypotheses are conducted. Empirical estimates, obtained using quarterly data for the yen–dollar exchange rate, reject the rational–expectations hypothesis and suggest that there exists a time–varying risk premium.  相似文献

In this article, we contribute to the current literature on market disciplining of the sovereign governments of the developing countries by distinguishing both sides of the market discipline hypothesis by adopting three‐stage least square estimation to incorporate the contemporaneous feedback effects between primary structural budget balances and the country's default‐risk premiums. We provide empirical evidence of a unidirectional causal relationship between a country's default‐risk premium and primary structural budget balances with the direction flowing from primary structural budget balances to country's risk premium in 40 developing countries over the period 1975–2008. We also employ the Arellano‐Bond dynamic panel generalized methods of moments estimation to control for this joint determination of primary structural budget balances and the country's default‐risk premium, and find supportive evidence of undisciplined sovereign governments and of nonlinearly behaving well‐functioning financial markets in the sample countries.

我国股权分置中对价水平的“群聚”现象分析   总被引:16,自引:3,他引:16  
从2005年4月29日到2006年3月19日止,上海证券市场共有25批次346家(含29家试点公司)上市公司公布股权分置改革的详细方案。其中高达87.6%股权分置公司的对价水平都集中在10送2至4股区间,平均对价水平为10送3股,对价水平出现显著的10送3股“群聚”现象。本文以不完全竞争市场理论为基础,对上海证券市场346家股权分置公司样本进行实证检验,结果表明,上海证券交易所前25批股权分置公司的保荐市场上,Herfindahl-Hirschman指数(HH指数)平均高达1411,保荐行业的市场准入难度较大,股权分置公司的对价水平与保荐机构所占市场份额显著负相关。证据表明,上海证券市场的保荐行业一定程度上属于寡头垄断,而10送3股的现象可能是寡头垄断的结果,而不是完全市场竞争的结果。  相似文献

Why do risk premia vary over time? We examine this problem theoretically and empirically by studying the effect of market belief on risk premia. Individual belief is taken as a fundamental primitive state variable. Market belief is observable; it is central to the empirical evaluation and we show how to measure it. Our asset pricing model is familiar from the noisy REE literature but we adapt it to an economy with diverse beliefs. We derive equilibrium asset prices and implied risk premium. Our approach permits a closed form solution of prices; hence we trace the exact effect of market belief on the time variability of asset prices and risk premia. We test empirically the theoretical conclusions. Our main result is that, above the effect of business cycles on risk premia, fluctuations in market belief have significant independent effect on the time variability of risk premia. We study the premia on long positions in Federal Funds Futures, 3- and 6-month Treasury Bills (T-Bills). The annual mean risk premium on holding such assets for 1?C12?months is about 40?C60 basis points and we find that, on average, the component of market belief in the risk premium exceeds 50% of the mean. Since time variability of market belief is large, this component frequently exceeds 50% of the mean premium. This component is larger the shorter is the holding period of an asset and it dominates the premium for very short holding returns of less than 2?months. As to the structure of the premium we show that when the market holds abnormally favorable belief about the future payoff of an asset the market views the long position as less risky hence the risk premium on that asset declines. More generally, periods of market optimism (i.e. ??bull?? markets) are shown to be periods when the market risk premium is low while in periods of pessimism (i.e. ??bear?? markets) the market??s risk premium is high. Fluctuations in risk premia are thus inversely related to the degree of market optimism about future prospects of asset payoffs. This effect is strong and economically very significant.  相似文献

This paper aims to extend the existing literature on foreign exchange rate risk pricing. Unlike the existing studies on Canada, we use six alternative bilateral and one multilateral exchange rate proxies. Furthermore, using both a two-factor and a three-factor capital asset pricing model (CAPM), we test for the presence of a long-run relationship among exchange rate risk pricing, herding behavior, term structure and the interest rate. The estimated results based on both the ordinary least squares (OLS) and generalized least squares (GLS) estimation techniques confirm that exchange rate risk in the Canadian equity market is priced and that the pricing of this risk is time-varying. This result holds for all seven exchange rate proxies. Our empirical analysis also suggests the presence of a long-run relationship among exchange rate risk pricing, herding behavior, term structure and the interest rate. This relationship is found to be insensitive to variations in the world market return.  相似文献

This note presents a simple joint test of existence of a risk premium in exchange rates and the rationality of expectations. It is shown that major currency prices studied in this note are subject to a risk premium.  相似文献

This study investigates whether U.S. investors, in pursuing of international diversification, are exposed to foreign exchange risk through the ownership of American depository receipts (ADRs) and if so, whether such risk is systematic. We find that returns of ADRs from countries such as the United Kingdom, Japan, and South Africa are sensitive to their corresponding foreign exchange rate fluctuations. Using a technique developed by Sweeney and Warga (1986), we estimate the risk premium associated with foreign exchange risk. The results suggest that the total foreign exchange risk is priced at equilibrium. However, the incremental foreign exchange risk that is not imbedded in the market returns does not command a risk premium. The evidence indicates that the incremental foreign exchange risk is diversifiable or can be effectively hedged.  相似文献

The Effect of Exchange Rate Volatility on Trade in Durables   总被引:1,自引:0,他引:1  
Because durable goods have the quality of an asset, risk-averse consumers wan to pay a lower price for durable than for nondurable goods so that they are compensated for the risk of price changes; they require risk premium. Since the exchange rate is a strong source of uncertainty in import prices, exchange rate volatility has a negative effect on the demand for imported durables. In an imperfectly competitive market, the volatility of the exchange rate is predicted to reduce the relative price of imported durables. The prediction is supported by an empirical investigation of US imports.  相似文献

This paper investigates the behavior of the risk premium on the Swiss stock market. The risk premium consists of two components, which are estimated separately: the amount of volatility and the unit price of risk. By estimating a bivariate GARCH-M model the volatility of the Swiss market is found to be strongly exposed to spillovers from the other major financial markets. To estimate the unit price of risk a Kalman filter procedure is employed, which allows for variability in this variable. Investors place a high price on risk, when the market is considered `expensive'. First version received: March 1998/final version received: July 1998  相似文献

EMS exchange rate expectations and time-varying risk premia   总被引:1,自引:0,他引:1  
In this paper we examine exchange risk premia employing a survey dataset of EMS exchange rates. We are able to test a risk premium model directly, i.e. without having to rely on the rational expectations assumption. Our results indicate that time-varying risk premia are present in almost all cases and that a GARCH-in-mean specification for the premium is often appropriate.  相似文献

Using a disaggregate survey database, this paper reexamines the issue of the existence of a time-varying risk premia in three foreign exchange markets. Previous research on this topic has utilised a consensus measure of the risk premium, based on the rational expectations assumption, and is not supportive of the existence of such a premium. In contrast, this paper reports compelling evidence in favour of time-varying risk premia for the British pound (BP), German mark (DM), and Japanese yen (JY) exchange rates. In particular, we demonstrate that consensus measures of the risk premium mask the existence of risk because of the importance of heterogeneous expectations.  相似文献

The major aim of this paper is to determine the appropriate estimation technique for testing the market efficiency hypothesis. The weak and semi-strong forms of the market efficiency hypothesis have been tested for five actively traded futures currency markets for the period 1974-86. The test has been carried out under the assumption of a constant risk premium.  相似文献

This paper provides a theory and evidence that the risk premium puzzle is viewed as a phenomenon pertaining to the unstable foreign exchange market. In an unstable market, revision error uncompensated by an initial risk premium accrues due to consumer expectation revision about the ex ante uncertainty of the exchange rate. The risk premium widely deviates from its initial level, depending on the frequency of the consumer expectation revision and the degree of risk aversion. Subsequent evidence shows the existence of the revision errors for the risk premium during the Asian currency crisis and the recent financial crisis periods.  相似文献
