Time-Varying Risk, Interest Rates, and Exchange Rates in General Equilibrium

Under mild assumptions, the data indicate that fluctuations in nominal interest rate differentials across currencies are primarily fluctuations in time-varying risk. This finding is an immediate implication of the fact that exchange rates are roughly random walks. If most fluctuations in interest differentials are thought to be driven by monetary policy, then the data call for a theory which explains how changes in monetary policy change risk. Here, we propose such a theory based on a general equilibrium monetary model with an endogenous source of risk variation—a variable degree of asset market segmentation.     

The ‘compensation’ thesis,as exemplified by the case of the Chinese central bank

This paper extends the theory of demand-led money supply endogeneity to the case of an open economy with a fixed exchange rate. This theory is contrasted to the standard Mundell-Fleming view. In the compensation approach advocated here, central banks are able to set interest rates, even in a fixed exchange rate regime, either because there are automatic market mechanisms that will induce the private sector to act in such a way that changes in foreign reserves will be compensated by opposite changes in central bank claims over the domestic economy, or because the central bank will engage in endogenous sterilization operations in its efforts to enforce its benchmark interest rate. Analyzing the balance sheet of the Chinese central bank, we find that the large rise in foreign reserves on the asset side is compensated by large positive changes in items of the liability side, mainly bonds issued by the central bank. Foreign reserves are not cointegrated with the monetary base, meaning that there is no long-run relationship between foreign exchange reserves and the supply of base money. We also find no long-run relation between foreign exchange reserves and the consumer price index.     

How is β related to asset returns?

Existing empirical evidence for the relevance of the β in modelling asset returns is mixed. Drawing on conditional tests of β first proposed by Pettengill, Sundaram and Mathur (1995) and extended by Bollen (2010), empirical evidence employing monthly data is presented that indicates that β is highly related to variability of asset returns but not to the level of asset returns. This result is consistent with the predictions of the market model but not with the predictions of the CAPM. It is concluded that β remains a useful construct in financial economics but may have a differing role in financial economics than the conventional wisdom asserts.     

An investigation of regime shifts in UK commercial property returns: a time series analysis

The random-walk hypothesis, vis-à-vis asset price, suggests that prices traded in a market cannot be predicted based on historical information. Employing unsecuritized UK commercial property returns, we analyse this hypothesis by investigating regime shifts or multiple changes in persistence in the series. Our results uncover regime shifts in both the aggregate and sector-specific data. Specifically, the shifts are less frequent in the Industrial sector, compared to the Office, Retail and Aggregate returns data. We highlight some implications for academics, practitioners and regulators.     

Exchange Rates and Long‐Term Bonds*

There is tentative evidence to suggest that the well‐documented empirical failure of uncovered interest parity (UIP) is confined to short‐term interest rates. However, tests of UIP for long‐term bonds are thwarted by various data problems. These data problems can be avoided by focusing on short investments in long‐term bonds. This paper concerns the relationship between changes in the US dollar–Deutsche Mark exchange rate and returns to short investments in US and German long‐term government bonds. The hypothesis that expected returns to investments in bonds denominated in the two currencies are equal is not rejected, and the estimated slope coefficients are positive. For corresponding short‐term interest rates, the typical finding of negative and large Fama coefficients is confirmed. We conclude that it is the maturity of the asset, rather than the investment horizon, that matters for the results.     

Informational efficiency: ranking markets

Summary. The paper studies informational properties of three types of imperfectly competitive markets: a one-signal speculative market (OSS market) in which agents have only private information about the fundamental value (v) of the risky asset traded, a two-signal speculative market (TSS market) in which agents have private information about both v and the asset supply, and a market in which agents are endowed with both information about v and shares of the risky asset traded. In this last market (JA market), agents have joint activities: they trade for both speculative and hedging purposes. It is shown that (i) the JA market and the OSS market are the most and the least efficient, respectively, and (ii) the levels of informational efficiency in the three markets are inversely correlated with the intensities with which traders use their private information about the fundamental value of the asset.

Price‐level versus inflation targeting with financial market imperfections

Abstract Price‐level targeting (PT) is compared with inflation targeting (IT) in a DSGE model augmented with imperfections in both debt and equity markets. The PT regime outperforms the IT regime, and the gain depends on the degree of financial market frictions. This is because inflation is better anchored under PT, owing to the expectation channel, and therefore the monetary authority has more leverage to deal with the financial market distortions. We also find that the gain is higher if the optimal rule reacts to asset prices instead of the output gap, and the rule requires a positive response to asset prices.     

Stochastic and structural fiscal policy in a monetary stationary economy

In the framework of a monetary asset pricing model which is simple enough to generate closed form formulae for equilibrium price functions the interactions between output, fiscal policy, and asset markets is investigated. With money yielding liquidity services in the exchange process real stock prices are negatively correlated with anticipated (stochastic) fiscal policy changes, while the impact of unanticipated (structural) fiscal policy on the stock market depends qualitatively on the ‘business cycle’ of the economy. It is shown that the monetary character of the economy, more precisely the role of money in the exchange process, is critical for the relationship between fiscal policy and real share prices. Moreover, while contingent fiscal policy measures may be successful in stabilizing the real interest rate on money they are incapable of achieving a stable term structure of the real rate on stocks. In contrast, uncontingently higher public expenditures generally promote the volatility of the real rates on financial assets.     

Do Aussie markets smile? Implied volatility functions and determinants

If options are correctly priced, the interpretation of volatility in the Black–Scholes model (as identifying the volatility of the underlying asset) is violated. The empirical relation between the model ‘implied volatility’ and the degree to which the option is in-the-money (moneyness) has been reported as resembling a U-shape (or ‘smile’) for options on currencies (and more of a ‘smirk’ for options on equities). In this article, using multivariate time-series analysis and employing an impulse response function, we investigate the structural relationships and dynamics of the volatility smile in relation to the option liquidity, key features of the underlying asset and market momentum. Our findings confirm evidence of a number of biases in the Black–Scholes model consistent with Chou et al. (2011) in regard to liquidity in both the underlying and the option itself, and with Peña et al. (1999) as to the importance of the option time to maturity. As well as delineating such biases as they co-relate both with each other and with the underlying asset volatility and momentum, we find that the pronounced smile is related to the differential sensitivities of in-the-money and out-of-the-money options, which itself suggests an explanation for the characteristic smile shape.     

The High‐Frequency Responses of Australian Financial Futures to Unexpected Cash Rate Announcements*

This study examines the high‐frequency responses of Australian financial futures to monetary surprises using intra‐day futures data. Using the event window method with tick data to control for the endogeneity between market interest rates and the cash rate, our empirical findings support the following. First, monetary policy announcements significantly impact not only short‐term interest rate futures but also longer‐term treasury security future markets. Second, the most significant responses of these markets occur in the event window that contains the policy announcement. Third, we also find that the monetary policy is not well anticipated by market participants until the Reserve Bank of Australia’s policy release.     

Profit persistence and stock returns

This article attempts to assemble further empirical evidence on the relationship between the product and the financial market. Drawing back on work in industrial organization, we analyse the relationship between profit persistence and factor-adjusted stock returns looking at about 2000 listed US firms over the last 34 years. While the relationship between (current, lagged and unexpected) profits/earnings and returns has been extensively analysed before, to our knowledge this is the first study to look at the relationship between stock returns and profit persistence. We interpret profit persistence as a result of market competition and innovation of the firm. It is shown that firm-specific long-run profit persistence after correction for other additional economic fundamentals of the firm has a positive impact on four-factor adjusted returns and a negative impact on their volatility.     

The Effect of Changes in Real Exchange Rates on Employment: Evidence from Manufacturing Industries in China, 1980–2002

This paper analyzes the effect of changes in real exchange rate on manufacturing employment. Our theoretical model predicts the positive effect of depreciation of real exchange rate on employment through a firm’s expectation on changes in real exchange rate and the interaction between real exchange rate and a firm’s import and domestic input. Using China’s manufacturing data during the 1980–2003 period, we find that depreciation of real exchange rate promotes employment growth in manufacturing industries, while change in real exchange rate is not a significant factor in promoting wage growth. We also find that an increase in export share offsets partially the effects of real exchange rate on employment and real wages. Translated from Journal of World Economy, 2005, (4): (in Chinese)     

The behaviour of unemployment and unfilled vacancies in Great Britain: a search-turnover View

Previous empirical estimates of the relationship between unemployment and unfilled vacancies in Great Britain have been obtained from a mis-specified model. In particular, past studies have attempted to estimate an equilibrium relation directly from observations which have in general been generated from disequilibrium states of the labour market. This paper presents and estimates a disequilibrium, job search-labour turnover model of the labour market, using quarterly British data, from which a static equilibrium ‘UV’ relationship can be derived. The empirical results suggest that there is no statistically significant equilibrium relationship between unemployment and vacancies in Great Britain. Consquently, the recent controversy over explanations for alleged for alleged shifts in this relationship may have been ‘much ado about nothing’.     

Portfolio allocation and international risk sharing

Abstract We show that recent explanations of the consumption‐real exchange rate anomaly that rely on goods and financial market frictions are not robust to introducing just one additional international asset. When portfolios are selected optimally, international trade in two nominal bonds implies a consumption‐real exchange rate correlation that is too high compared with the data even when there are many shocks. Monetary policy specification plays a potentially important role for the degree of risk sharing provided by nominal bonds, both in the benchmark model with only tradable and non‐tradable sector supply shocks and also in the model that allows for news.     

REGULATORY FORBEARANCE AND DEPOSITOR MARKET DISCIPLINE: EVIDENCE FROM SAVINGS BANKS IN KOREA

This paper investigates whether regulatory forbearance for savings banks in Korea affects the market discipline of depositors using data from 2000 to 2010, which are characterized by a series of exits of savings banks. We find that depositors' sensitivity to the savings banks' asset quality decreases when there is regulatory forbearance for failing savings banks. This forbearance effect is also observed in the behavior of the depositors of the neighboring savings banks in the same business area. These results suggest that regulatory forbearance may cause depositors to misjudge bank risks, increasing the expected costs of bank failure. (JEL G21, G28)     

“Expiration hour effect of futures and options markets on stock market” — A case study on NSE (National Stock Exchange of India)

This paper studies the effect of expiration day of the Index futures and Options on the trading volume, variance and price of the underlying shares. The impact of derivatives trading on the underlying stock market has been widely documented in the Finance literature. In particular, significant differences in the statistical properties of asset returns (for instance, mean and variance) during expiration and non-expiration days have been advanced as an evidence for the destabilization effect (or lack there of) of derivative instruments. The earlier studies have, however, drawn their conclusions without rigorously modelling the underlying stochastic data generation process. Given that the statistical properties mentioned before are merely traits of the asset returns, this approach can lead to spurious results if analyzed in isolation of the underlying process. We propose to address this crucial shortcoming by examining the expiration day effect from a GARCH (Generalized Auto Regressive Conditional Heteroskedastic) framework. We use both daily and high frequency (5 min and 10 min) data on S&P CNX Nifty Index. Our central finding using intra-day data is that while there is no pressure – downward or upward – on index returns, the volatility is indeed significantly affected by the expiration of contracts. This effect, however, doesn’t show up in daily data.     

Designing the optimal public pension system

This paper uses a two‐period overlapping generations model in order to provide a theoretical design for the optimal public pension system based on a partial equilibrium analysis. Household preferences depend on two periods' consumption and leisure and are positively homogeneous of degree m with respect to consumption in the working and retired periods. We present characteristic features of the optimal public pension system in this paper. First, differences in the population growth rate do not affect the large/small relation between the optimal net lifetime burden rates of generations. Second, we present the optimal public pension system explicitly if m < 1 and m ≠ 0. Third, the difference between the market time‐preference rate and the social time‐preference rate provides a crucial insight into the optimal burden rate of each generation.     

The Impact of Fixed Exchange Rates on Fiscal Discipline

In this paper, it is shown that contrary to standard arguments, fiscal discipline is not substantially enhanced by a fixed exchange rate regime. This study is based on data from 116 countries collected from 1975 to 2004, and uses various estimation techniques for dynamic panel data, in particular a generalized method of moments estimation in the tradition of Arellano and Bover [Journal of Econometrics (1995), 68 , 29] and Blundell and Bond [Journal of Econometrics (1998), 87 , 115]. Contrary to previous papers on this topic, the present paper takes into account that the consequences of a new exchange rate regime do not necessarily fully manifest immediately.     

Investigation of institutional changes in the UK housing market using structural break tests and time-varying parameter models

This paper investigates the effects of institutional changes within the UK housing market in recent decades using structural break tests and time-varying parameter models. This approach is motivated by models of institutional change drawn from the political science literature which focus on the existence of both fast-moving and slow-moving institutional changes and the interactions between them as drivers of the dynamics of asset prices. As a methodological contribution, we use several time-varying parameter models for the first time in investigations of institutional change. Our findings support the existence of both structural breaks and continuous variance in parameters. This contributes to our understanding of the housing market in two respects. Firstly, the dates of structural breaks appear to better match unexpected market shocks rather than remarkable political events, and this supports prior institutional theory. Secondly, assessment of the effect of slow-moving institutional changes shows that people’s biased expectations rather than the economic fundamentals have increasingly played an important role in driving housing prices in the short run although fundamentals continue to drive house prices to converge to their long-run equilibrium.     

Global Investment Environment of the Post‐Quantitative Easing World: The ‘new‐old’ and ‘new‐new’ Normal

Global markets since late 2007 are not ‘normal’, where normal means market conditions we would expect to observe going forward in the absence of any new economic shocks. Financial markets have been dominated by extraordinary central bank policies that were created to deal with challenging market conditions reflecting heightened risk aversion and illiquidity. Markets in the future will have some characteristics that look more like the market conditions observed in the pre‐crisis period, which I call the ‘new‐old normal’ and other conditions that differ from the past, which I call the ‘new‐new normal’. I first review what happened during the financial crisis in terms of developments in three asset classes, equities, fixed income and currencies, to place the forward‐looking view in proper context. Then the transition period from the quantitative easing (QE) era of exceptional monetary policy to post‐QE markets is discussed. Post‐transition, we will see some features of the post‐QE world that will resemble pre‐crisis market conditions, the ‘new‐old normal’ with higher policy interest rates, wider cross‐country interest differentials, lower cross‐asset return correlations and a resurgence of the importance of cross‐country differences in fundamentals in international investing. However, some features of the post‐QE investment environment will be unlike anything observed in the past: the ‘new‐new normal’ with reduced liquidity and more days of exceptionally large volatility and asset price moves due to regulatory effects resulting in a reduced ability of market‐makers to provide inventory buffers for counterparties and electronic trading venues that shut down trading in high volatility periods; low inflation; flatter yield curves; and emerging markets providing less opportunity for diversification gains as they converge to developed financial market characteristics.
