The Mixture Of Distribution Hypothesis And The Russian Stock Market

According to the mixture of distributions hypothesis (MDH), a serially correlated mixture of variables measuring the rate at which information arrives to the market explains the GARCH effects in stock returns. While reasonable amount of empirical evidence supports this hypothesis for developed, highly liquid stock markets in industrial countries, the current literature does not provide much findings for stock markets in countries that have recently experienced the transition from economic planning to capitalism. Hence, the purpose of this paper is to provide a first piece of evidence for one of the newly created stock market, the Russian stock market. Examination of the relationship between risk, returns, volatility and volume existing in the Russian stock market provides evidence in support of the MDH and suggests that even in emerging and turbulent markets risk and returns are jointly integrated to the flow of information arriving to the market

The Augmented SOLOW Model And The OECD Sample

In their influential work on the augmented Solow model, Mankiw, Romer and Weil (1992) showed that cross-section evidence was reasonably consistent with the Solow growth model augmented to include human capital for a wide range of countries.  However, for the sample of OECD countries, they found that the model had low explanatory power and underestimated the output elasticity of physical capital. We revisit their seminal work using data from the recently released version 6.1 of the Penn World Table. We find that the ability of the augmented Solow model to explain the cross-country variation in income per capita in the OECD sample improves significantly. Our results highlight the importance of taking into account changes that take place over time in the collection and measurement of national accounts data in estimating and testing the augmented Solow model

Globalization, Long Memory, and Real Interest Rate Convergence: A Historical Perspective.

Globalization, a complex phenomenon, reflects the interaction of many technological, cultural, economic, social, and environmental trends. This paper investigates a narrow aspect of three waves of globalizations that occurred in the last 150 years, which refers to the stochastic properties of real interest rates and real interest rate differentials using fractional integration methods. The empirical results provide evidence that in all three globalization waves rejects the hypothesis that a unit root exists in the real interest rate series and supports the hypothesis of real interest rates converge across countries. We fail to find evidence, however, that the results are uniformly consistent across the three waves, suggesting that each globalization involves its own distinct stochastic dynamics.pre-print674 K

Persistence and cyclical dynamics of US and UK house prices: Evidence from over 150 years of data.

This paper provides a new and unique look at the dynamics and persistence of historical house prices in the USA and the UK using fractional integration techniques not previously applied to housing markets. Unlike previous research, we consider two components of persistence of house prices: the component associated with the long-run trend and the component associated with the cycle. We find evidence of cyclical and long-run persistence in the UK housing markets. In contrast, we fail to find evidence of cyclical persistence for the USA. For the sub-samples, which account for a structural break in each series, an important difference is the asynchronous pattern of the breaks, an indication of heterogeneity in the house price dynamics of the two countries and a sign that national rather than global events have played an important role. Although the house price movements of the last decade are dramatic, the greatest structural changes in the overall nominal and real price dynamics of the UK and the USA appear to have taken place much earlier, in the late 1970s and early 1980s in the UK and in the mid-1950s and early 1970s in the USA. An important result, common to the whole and sub-samples, is that long-run persistence plays a greater role than cyclical persistence in explaining the dynamics of house prices in both countries. These findings have substantial implications for policy decisions.pre-print776 K

Time-varying persistence of inflation : evidence from a wavelet-based approach

We propose a new long-memory model with a time-varying fractional integration parameter, evolving non-linearly according to a Logistic Smooth Transition Autoregressive (LSTAR) specification. To estimate the time-varying fractional integration parameter, we implement a method based on the wavelet approach, using the instantaneous least squares estimator (ILSE). The empirical results show the relevance of the modeling approach and provide evidence of regime change in inflation persistence that contributes to a better understanding of the inflationary process in the US. Most importantly, these empirical findings remind us that a "one-size-fits-all" monetary policy is unlikely to work in all circumstances.http://www.degruyter.com/view/j/snde2018-09-30am2017Economic

Does real U.K. GDP have a unit root? Evidence from a multi-century perspective

We employ linear and nonlinear unit-root tests to examine the stationarity of five multi-century historical U.K. series of real output compiled by the Bank of England. Three series span 1270 to 2016 and two series span 1700 to 2016. These datasets represent the longest span of historical real output data available and, thus, provide the environment for which unit-root tests are most powerful. A key feature of our test is its simultaneous allowance for two types of nonlinearity: time-dependent (structural breaks) nonlinearity and state-dependent (asymmetric adjustment) nonlinearity. The key finding of the test, contrary to what other more popular nonlinear unit-root tests suggest, provides strong evidence that the main structure of the five series is a stationary process characterized by an asymmetric nonlinear adjustment and a permanent break affecting both the intercept and the trend. A major policy implication of this finding is fiscal and/or monetary stabilization policies have only temporary effects on the output levels of the United Kingdom.http://www.tandfonline.com/loi/raec202021-03-03hj2019Economic

The behavior of real interest rates: new evidence from a “suprasecular” perspective

We examine the temporal dynamics of the historical series of real interest rates for France, Germany, Italy, Japan, the Netherlands, Spain pre-1730 and post-1800, the United Kingdom, and the United States stretching back to the 14th century. We use the Robinson approach to determine the fractional order of integration and examine both linear deterministic trends and multiple smooth breaks. In the latter case we make use of the Chebyshev polynomials in time. With the exception of two countries (Italy and France), where the linear model appears more appropriate, our results reveal evidence that real interest rates are driven by the interaction between nonlinearities in the deterministic trends and fractional integration processes. They suggest that real interest rates are mean-reverting but not as persistent as suggested in the literature. In particular, the nonlinear model with autocorrelated errors provides no evidence of long memory, which questions most of the literature on real interest rates. The implications of these results are relevant to evaluate the effectiveness of policy interventions and the theoretical implications of different macroeconomic models as shocks affecting real interest rates will dissipate by themselves.Data are available at: https://www.bankofengland.co.uk/working-paper/2020/eight-centuries-of-global-real-interest-rates-r-g-and-the-suprasecular-decline-1311-2018Http://wileyonlinelibrary.com/journal/infihj2022Economic

Globalization, long memory, and real interest rate convergence : a historical perspective

This paper investigates whether the real interest rate parity (RIRP) is valid during the three waves of globalizations that occurred in the last 150 years (1870–1914, 1944–1971, 1989 to the present). If any, these periods should favor RIRP, since globalization is a process where economies and financial markets become increasingly integrated into a global economic system. In contrast to the existing literature, we model the departures from RIRP as a long-term memory process and apply fractional integration methods on a sample of real interest rate differentials of seven developed countries: France, Germany, Holland, Italy, Japan, Spain, and the UK across the three globalization waves paired against the USA. We compute impulse response functions (IRF) to gain further insight into the memory characteristics of the RIRP differential processes and provide half-life estimates. We find that deviations from RIRP are mean reverting, providing robust evidence of real interest rate convergence during the three globalization waves. We shed further light on financial and commodity market integration during the three globalization waves by assessing the memory properties of uncovered interest rate parity (UIP) and relative purchasing power parity (PPP) differential processes. We find that deviations from relative PPP and UIP are not always mean-reverting processes. RIRP, relative PPP, and UIP hold simultaneously only in 7 out of 21 cases; RIRP and UIP hold in 11 out of 21 cases; RIRP hold without the support of relative PPP and UIP in 3 out of 21 cases. Thus, the evidence in favor of real interest rate convergence appears to be driven more by UIP than relative PPP. All these results are, to the authors knowledge, new to the literature.http://link.springer.com/journal/181hj2022Economic

Modeling US historical time-series prices and inflation using alternative long-memory approaches

We consider two important features of the historical US price data (1774–2015), namely the data’s persistence and cyclical structure. We first consider the persistence of the series and focus on standard long-memory models that incorporate a peak at the zero frequency. We examine different models with respect to the deterministic terms, including nonlinear deterministic trends of the Chebyshev form. Then, we investigate a more general model that includes both persistence and cyclicality of the series and, thus, includes two fractional integration parameters, one at the zero (long-run) frequency and the other at the nonzero (cyclical) frequency. We model the cyclical structure as a Gegenbauer process. This specification outperforms the standard long-memory specifications. We find that the order of integration at the zero frequency is about 0.5, and the one at the cyclical frequency is about 0.2 with cycles repeating approximately every 6 years, producing mean-reverting long-memory effects at both the zero and cyclical frequencies. Fitting the values to this model, however, we discover the presence of a break that, according to the methods employed, takes place at around 1940–1941. The results indicate the prevalence of the long-run or zero component with a much higher degree of persistence during the second post-1940–1941 subsample, suggesting important implications for monetary policy.Luis A.
