This paper presents tests for the null hypothesis of no regime switching in Hamilton’s (Econometrica 57:357–384, 1989) regime
switching model. The test procedures exploit similarities between regime switching models, autoregressions with measurement
errors, and finite mixture models. The proposed tests are computationally simple and, contrary to likelihood based tests,
have a standard distribution under the null. When the methodology is applied to US GDP growth rates, no strong evidence of
regime switching is found.

The long-run relationship between nominal interest rates and inflation is examined, allowing for structural breaks and asymmetric mean reversion. From a Threshold AutoRegressive (TAR) test applied to the residuals of the cointegration relationship (while allowing for both a break in the mean of the long-run equation and a smooth regime-transition), there is strong evidence for non-linear mean reversion properties for the real interest rates of the US Treasury Bill market. This suggests asymmetric changes to inflation shocks in the Central Bank's reaction function. The existence of different regimes is consistent with some interpretations of the monetary policies run by the Fed, such as credibility and opportunism. 相似文献

Previous studies on PPP have tested either the null hypothesis of non-stationary or the null of a stationary real exchange rate and used the US as the base country and focused on industrialized countries. It has been argued that testing either null is insufficient to confirm the presence of PPP. It has also been noticed that the results are sensitive to the choices of the base country; for instance, the US versus Germany. In contrast to previous studies, this paper uses different unit root tests, confirmatory analysis, and different base countries to test PPP for a sample of developing countries in Asia during the current float. Overall, the results do not seem to be sensitive to the choice of the base country, and joint rejections are not present but joint non-rejections are far more common. Using Perron's test, which allows for a one-time break in the series, the results indicate evidence of stationarity for Indonesia, Korea, Malaysia and Thailand when the US is the base country. When Japan is the base country, evidence of stationarity is detected only for Indonesia. 相似文献

This article considers bidirectional nonlinear cointegration relation between FDI and industrial output in Turkey. The data cover the monthly period 2005:1–2013:10 for the time series of total industrial production, 36 sub-industrial sectors’ production and FDI. Following nonlinear threshold cointegration and VECMs, the article yields that (i) total industrial production and nine sub-industrial productions have positive long-run impact on FDI with significant error corrections, (ii) six sub-industrial productions have short-term influence on FDI, (iii) FDI has long-run positive impulse on total industrial production and nine sub-industrial productions with some significant error corrections and (iv) FDI affects four sub-industrial productions in the short run as well as in the long run. The results of VECMs from (i) also reveal that the all short-term adjustment parameters are found significant and powerful in 10 typical regimes (Regime-1s) and in 5 extreme regimes (Regime-2s). Finally, the outcome of VECMs from (iii) yields that short-term adjustment parameters are found significant and powerful in two typical regimes and in four extreme regimes. Eventually, considering FDI’s positive impact in the short and long run, this article suggests that policymakers promote specifically the FDI inflows to the sectors of intermediate goods, manufacture of beverages, manufacture of rubber and plastic and manufacture of other nonmetallic mineral products. 相似文献

The article brings new evidence that intra Euro Area trade imbalances should be thought of as the outcome of the interaction of opposing growth strategies between northern/surplus countries (Austria, Belgium, Germany, Netherlands) and southern/deficit countries (France, Italy, Portugal, Spain). By using a vector autoregression model, econometric evidence clarifies that the demand regime in the southern region is wage-led, while profit-led in the northern region. Moreover, a downward-wage adjustment in the northern region (negative wage shock) contributed to increasing the intra-EA trade surplus vis-à-vis the southern region by far more than an upward-wage adjustment in the southern region (positive wage shock). 相似文献

We investigate the long run relationship between private consumption and disposable income for a sample of EU countries using recently developed panel cointegration techniques. For the ordinary consumption-income model the evidence on cointegration is ambiguous. In addition, the cointegration vector obtained by efficient estimation methods is not consistent with theoretical reasoning, as it reflects a decline in the savings rate over time. Extending the analysis by financial wealth improves the model fit markedly. In particular, the income elasticity is not different from 1 and therefore in line with the life cycle permanent income hypothesis. The marginal propensity to consume out of financial wealth is in a range of 3–5%, thereby confirming recent time series results. 相似文献

In this paper we propose a number of nonlinear panel unit root tests that are robust to cross-sectional dependency. These tests may be used to test the null hypothesis of non-stationarity against the alternative that some or all of the time series in the system of equations follow a stationary exponential smooth transition autoregressive (ESTAR) process. In contrast to previous research we relax the assumption that the cross-correlation structure is driven by a common-factor and consider an endogenous correlation structure. Based on the size and power results from the Monte Carlo simulations we recommend using the Wald version of our cross-sectional dependent robust nonlinear panel unit root (CDR-NPU) method.Finally, in an empirical application we demonstrate that our more powerful nonlinear method, in contrast to previous methods, can provide support for PPP even in smaller samples. In consistency with the univariate tests in Bahmani-Oskooee et al. (2008) our CDR-NPU tests support the theory that less industrialized economies exhibit stronger and more distinct nonlinear adjustment patterns towards PPP. 相似文献

This article outlines a panel data approach to modelling the term structure of interest rates in the short and in the long run. We find robust evidence supporting the expectations hypothesis of the term structure (EHTS) for a small sample of Asian emerging markets. Furthermore, we detect some relevant differences in the transmission mechanism of monetary policy, and the existence of a McCallum (2005) rule (no exogeneity of monetary policy to the yield curve) in some countries. Finally, we document the influence of an international global factor (i.e. a time-varying global risk premium) on the yield curve, while local country-specific factors are not statistically significant. 相似文献

This study examines the purchasing power parity theory for 14 African countries by applying a recent composite time series method that incorporates the Fourier approximation. The structural breaks are modelled as a gradual smooth process by means of a Fourier component. The Fourier unit root test failed to find any evidence showing that real exchange rates for these 14 countries have mean-reverting tendencies. However, both cointegration and Fourier cointegration tests detect a stable long-term relation between the nominal exchange rate and relative price levels for 8 out of 14 countries; moreover, for five countries Fourier component in cointegration analysis is found to suit quite well. 相似文献

Tests for cointegration with two unknown regime shifts with an application to financial market integration 总被引:1,自引:0,他引:1
Abdulnasser Hatemi-J 《Empirical Economics》2008,35(3):497-505
It is widely agreed in empirical studies that allowing for potential structural change in economic processes is an important
issue. In existing literature, tests for cointegration between time series data allow for one regime shift. This paper extends
three residual-based test statistics for cointegration to the cases that take into account two possible regime shifts. The
timing of each shift is unknown a priori and it is determined endogenously. The distributions of the tests are non-standard.
We generate new critical values via simulation methods. The size and power properties of these test statistics are evaluated
through Monte Carlo simulations, which show the tests have small size distortions and very good power properties. The test
methods introduced in this paper are applied to determine whether the financial markets in the US and the UK are integrated.

This study applies a simple and powerful nonlinear rank test, proposed by Breitung (2001) to test the validity of long-run Purchasing Power Parity (PPP) in a sample of East Asian countries over the period March 1985–September 2008. The empirical results indicate that PPP holds for all of East Asian countries studied and the nominal exchange rate, domestic Consumer Price Index (CPI) and the US CPI are all linearly interrelated with the exception of China. Our results have important policy implications for these East Asian countries under study. 相似文献

The present paper examines the empirical adequacy of the expectations hypothesis of the term structure of interest rates in the context of the current debt crisis. Using a sample consisted of the five largest EU countries, namely France, Germany, Italy, Spain and the United Kingdom, and accounting for structural breaks in the data, I investigate cointegration, spread stationarity, validity of the cross-equation restrictions implied by the theory, and the possibility of excess returns. Overall, the empirical findings are against the EHTS for the whole maturity spectrum, implying evidence of economically important deviations from the theory. Only for specific spreads of France, Germany, Italy and the United Kingdom there is some evidence in favour of the expectations hypothesis. 相似文献

ABSTRACTAlmost all empirical research that has attempted to assess the validity of the Porter hypothesis (PH) has started from reduced-form models, for example, single-equation models for estimating the contribution of environmental regulation to productivity. This paper follows a structural approach that allows testing what is known in the literature as the ‘weak’ and the ‘strong’ version of the PH. Our ‘Green Innovation’ model includes three types of eco-investments to explain differences in the incidence of two types of eco-innovation, which are allowed to affect labor productivity. We allow for complementarity between the two types of eco-innovations. Using a comprehensive panel of Dutch manufacturing firm-level data we estimate the relative importance of environmental regulations on eco-investment and eco-innovations. The results of our analysis show a strong corroboration of the weak and a nuanced corroboration of the strong version of the PH. 相似文献

Abstract The paper proposes and applies statistical tests for poverty dominance that check for whether poverty comparisons can be made robustly over ranges of poverty lines and classes of poverty indices. This helps provide both normative and statistical confidence in establishing poverty rankings across distributions. The tests, which can take into account the complex sampling procedures that are typically used by statistical agencies to generate household‐level surveys, are implemented using the Canadian Survey of Labour and Income Dynamics (SLID) for 1996, 1999, and 2002. Although the yearly cumulative distribution functions cross at the lower tails of the distributions, the more recent years tend to dominate earlier years for a relatively wide range of poverty lines. Failing to take into account SLID’s sampling variability (as is sometimes done) can inflate significantly one’s confidence in ranking poverty. Taking into account SLID’s complex sampling design (as has not been done before) can also decrease substantially the range of poverty lines over which a poverty ranking can be inferred. 相似文献

Conventionally, the money demand function is estimated using a linear regression of the logarithm of money demand on a number of variables. In this article, we aim to estimate the long-run properties of money demand specification for a number of East Asian economies and within a panel framework with the presence of structural breaks. Various country-specific coefficients are allowed to capture inter-country heterogeneities. Consistent with theoretical postulates, it is found that (a) the demand for money in the long-run positively responds to real income and inversely to the interest rate spread, inflation, the real effective exchange rate and the US real interest rate; (b) the long-run income elasticity is greater than unity; and (c) both the currency substitution and capital mobility hypotheses hold. The empirical findings in this article can provide useful policy guidelines to the East Asian countries’ central banks in their quest for price stability. If one of the primary objectives of these countries is to minimize price instability, they should avoid creating unnecessary disequilibrium in the money market, while the employment of cointegration with the presence of structural breaks clearly recommends to central banks to use the supply of money to attain price and macroeconomic stability. 相似文献

Anti-dumping measures have been increasingly common. When imposed, the measures will always reduce trade with named countries.
Depending on market structure, there can also be price effects and increased imports from non-named countries. In this paper
we investigate relationships between prices to obtain information about the market structure. Using only prices will in many
cases be an advantage because of the greater availability of price data. An empirical example is provided using the US case
against Norwegian salmon.

This article extends the Lagrange multiplier (LM) cointegration test proposed by Westerlund and Edgerton (WE 2007) by allowing for an unknown number of breaks. Monte Carlo simulations provide two main results. First, a loss of power in the LM cointegration tests is detected when potential multiple breaks are ignored. Second, the modified testing procedures do not affect the asymptotic distribution and major properties of the tests of WE under the null, but noticeably increase their testing power in presence of multiple breaks. We also provide empirical applications of the proposed tests for the forward rate unbiasedness hypothesis (FRUH). The results reveal that the FRUH does hold when the effects of the multiple structural breaks are taken into account. 相似文献

Using a macro dynamic model that is specified for the current Chinese economy, we investigate the monetary policy in China
under the assumption that the capital market was “open” under WTO frame-work while the exchange rate was fixed. Our purpose
here is to find whether it is possible for China in this case to keep the effective monetary policy for stabilizing the domestic
economy. For this, we suggest some institutional arrangements (or restrictions). Given these institutional restrictions, we
find that not only the monetary policy can still be effective but also the fixed exchange regime will strengthen the macroeconomic
stability shared by both the domestic economy and the economy of its trade partners. The dynamic analysis of the model further
shows that the under-valued RMB is necessary for the target exchange rate to be sustainable. Finally, due to the import pattern
of the current Chinese economy, RMB appreciation will not help to resolve the trade deficit problem in the Western economy
with respect to China.

随着经济的高速增长.我国已经成为全球名列前茅的能耗大国,而近年来世界能源价格普遍上涨使得长期以来处于粗放型增长阶段的我国工业生产逐渐面临能源瓶颈。以高能耗为代价的产值增长不符合科学发展观的要求,也不利于经济保持长期增长的活力。本文通过建立计量模型研究发现,我国工业企业并没有足够的自主激励进行提高能源利用效率的技术投入,进而应用机制设计理论建立博弈模型分析了政府在激励企业加大能源循环利用的技术投入、实现经济的和谐增长过程中所应进行的制度安排。 相似文献

Externalities caused by human capital accumulation have taken up considerable space in theoretical work on economic growth. However, less attention has been paid to this externality in traditional growth accounting exercises. This paper takes up the issue of growth accounting, suggesting a framework for quantifying human-capital externalities and illustrating it empirically using data from the five Nordic countries. Four sources of growth are identified, i.e. capital accumulation, labor force growth, and total factor productivity growth (TFP), where the traditional TFP measure is split into a part explained by human-capital formation and an unexplained part. By doing this I am able to attribute between 12 per cent and 33 per cent of growth in the Nordic countries to human capital investment. 相似文献
