Is Asian per capita GDP panel stationary?

The goal of this paper is to examine whether per capita GDP for 15 Asian countries is panel stationary. We apply a panel test for stationarity that allows for multiple structural breaks developed by Carrion-i-Silvestre et al. (Econ J 8: 159–179, 2005). Our main findings are: (1) when we apply conventional tests, such as the ADF and KPSS univariate tests without structural breaks, we find little evidence for stationarity; (2) when we apply the KPSS univariate test with multiple structural breaks, we find evidence of stationarity for 10 out of 15 countries; and (3) when we apply the KPSS panel test with multiple structural breaks, we find overwhelming evidence of panel stationarity of per capita real GDP for different panels of Asian countries.      

Forecasting output gaps in the G-7 countries: the role of correlated innovations and structural breaks

Trend GDP and output gaps play an important role in fiscal and monetary policy formulation, often including the need for forecasts. In this article, we focus on forecasting trend GDP and output gaps with Beveridge-Nelson trend-cycle decompositions trend-cycle decompositions and investigate how these are affected by assumptions concerning correlated innovations and structural breaks. We evaluate expanding window, one-step-ahead forecasts indirectly for the G-7 countries on the basis of real GDP growth rate forecasts. We find that correlated innovations affect real GDP growth rate forecasts positively, while allowing for structural breaks works for some countries but not for all. In the face of uncertainty, the evidence supports that in making forecasts of trends and output gap policy-makers should focus on allowing for the correlation of shocks as an order of priority higher than unknown structural breaks.     

Okun's Law Does the Austrian unemployment–GDP relationship exhibit structural breaks?

Okun's Law postulates an inverse relationship between movements of the unemployment rate and the real gross domestic product (GDP). Initial empirical estimates for US data indicate that a two to three percent GDP growth rate above the natural or average GDP growth rate causes unemployment to decrease by one percentage point and vice versa. In this investigation we check whether this postulated relationship exhibits structural breaks by means of Markov-Chain Monte Carlo methods. We estimate a regression model, where the parameters are allowed to switch between different states and the switching process is Markov. As a by-product we derive an estimate of the current state within the periods considered. Using quarterly Austrian data on unemployment and real GDP from 1977 to 1995 we infer only one state, i.e. there are no structural breaks. The estimated parameters demand for an excess GDP growth rate of 4.16% to decrease unemployment by 1 percentage point. Since only one state is inferred, we conclude that the Austrian economy exhibits a stable relationship between unemployment and GDP growth.

Testing for structural breaks in factor loadings: An application to international business cycle

This paper proposes the implementation of the SupWald test of Andrews (1993) to detect structural breaks in the loadings of a static factor model. The procedure is illustrated by testing for structural breaks in the common factors of GDP growth series for a sample of advanced countries from 1950 until 2006.     

OUTPUT GROWTH AND STRUCTURAL REFORM IN LATIN AMERICA: HAVE BUSINESS CYCLES CHANGED?

This paper documents important changes in real gross domestic product (GDP) growth of six large Latin American countries. The main results can be summarized as follows. First, there is evidence of a structural break in real GDP toward stronger mean growth and a substantial reduction in volatility. Second, the timing of the breaks suggests that the important changes in economic policies of the 1980s and 1990s have been effective in permanently improving economic growth in the region. These changes in the growth processes imply recessions that are shorter in duration and milder in amplitude. The sustained increase in commodity prices observed in recent years explains an important share of growth in the region since 2003. But after accounting for the effect of commodity prices, there is even stronger evidence of a structural break in real GDP growth. (JEL E32)     

Modelling inbound international tourism demand in small Pacific Island countries

ABSTRACT

In this study, we estimate inbound international tourism demand models at the individual source market-destination and overall destination levels for Fiji, Cook Islands, Tonga and Vanuatu from 2002Q1 to 2016Q2 and Samoa from 2002Q4 to 2015Q3. Tourism demand is measured by visitor arrivals, tourism prices, the source country’s real GDP, tourism prices in substitute destinations, seasonality and structural breaks, all of which are considered plausible determinants. The models are estimated using the ARDL-bounds approach, structural breaks are identified using the Bai and Perron break test, and seasonality is tested using the US Census Bureau’s X-13 ARIMA-SEATS methodology. The study is important because it presents new evidence on price, income, and substitute price sensitivity, word of mouth, seasonality, and structural-breaks effects in Pacific island destinations.     

Fourier ADL cointegration test to approximate smooth breaks with new evidence from Crude Oil Market

Economic data is typically subject to a number of different forms of structural breaks. Ignoring structural breaks in a model can lead to misspecification issues and false conclusions. This paper proposes a new Autoregressive Distributive Lag (ADL) cointegration test in the presence of nonlinear breaks approximated by a Fourier function. The test offers a simple way to capture smooth structural change in time series data. Exact break dates are not required, and the suggested methodology can accommodate unknown number and form of gradual structural change. The testing procedure circumvents the potential power loss which can result from adding more dummy variables in the testing equation. Simulation results show that our procedure has good size and power properties. We demonstrate our test on the empirical example of real oil prices, oil production, and real economic activity, which are subject to structural breaks. The new test suggests that variables are cointegrated, while a conventional ADL test ignores structural breaks and concludes the opposite. This result casts some doubt on conventional oil price models.     

Structural change and foreign direct investment: globalization and regional economic integration

This paper investigates flows of inward and outward foreign direct investment (FDI) and FDI-to-GDP ratios in a sample of 62 countries over a 30 year time span. Using several endogenous structural break procedures (allowing for one and two break points), we find that: (1) the great majority of the series have structural breaks in the last 15 years, (2) post-break FDI and FDI/GDP ratios are substantially higher than the pre-break values, and (3) most breaks seem to be related to globalization, regional economic integration, economic growth, or political instability. Static and dynamic panel-data analyses accounting for and/or addressing endogeneity, simultaneity, nonstationarity, heterogeneity and cross-sectional dependence show that FDI is negatively related to exchange rate volatility and GDP per capita, but positively related to some regional integration agreements, trade openness, GDP, and GDP growth. Most notably, the European Union is the only regional economic integration unit found to consistently have significant and positive effects on FDI.     

A New Test of the Real Interest Rate Parity Hypothesis: Bounds Approach and Structural Breaks

The real interest rate parity hypothesis is tested using data for the group of seven industrialized countries (G7) over the period 1970–2008. The contribution is two‐fold. First, the paper utilizes the bounds approach in order to overcome uncertainty about the order of integration of real interest rates. Second, a test is made for structural breaks in the underlying relationship using a multiple structural breaks test. The results indicate significant parameter instability and suggest that, despite the advances in economic and financial integration, real interest rate parity has not fully recovered from a breakdown in the 1980s.     

Is fiscal policy stationary in China? A regional study by local government

In this study, we apply a stationarity test with a flexible Fourier function proposed by Enders and Lee (2012) to test the stationarity of the deficit–GDP ratio in China. We find that our approximation has a higher power to detect U-shaped breaks and to smooth breaks than the linear method if the true data-generating process of the deficit–GDP ratio convergence is, in fact, a stationary non-linear process. The results show that the stationarity for fiscal policy varies across different regions and that the deficit–GDP ratio of half of the regions is stationary. The results related to the budget structural balance and the fiscal deficit indicate no expansion in the Eastern and Central regions. We find that China's provinces in these two regions meet the stability theory of fiscal policy in the current stage of development. The deficit–GDP ratio is not stationary in the Western and Northeastern regions. These results indicate that the fiscal deficits in these regions are expanding and cannot be controlled by automatic market adjustment, and the government should therefore avoid deficit expansion in favor of a balanced budget policy.

Testing for structural breaks in panel varying coefficient models: with an application to OECD health expenditure

In this article, we propose a model selection approach for testing structural breaks in a semiparametric panel varying coefficient model. Monte Carlo evidence shows that the proposed model selection approach performs well in finite sample settings. Applying the method to an empirical data, we find evidence of structural breaks in Organisation for Economic Co-operation and Development (OECD) health expenditure data by allowing for income elasticity to be state (income)-dependent. The relationship between health expenditure and income is subject to two types of structural changes: smooth changes over income and structural breaks in the time dimension. The findings hold for both foreign exchange rate-converted and Purchasing Power Parity-converted expenditure and GDP.     

DOES DISAGGREGATION AFFECT THE RELATIONSHIP BETWEEN HEALTH CARE EXPENDITURE AND GDP? AN ANALYSIS USING REGIME SHIFTS*

This paper investigates the impact of policy shifts on disaggregated health expenditure‐GDP relationship in Australia. In contrast to previous studies the disaggregation is at the level of type of service delivered and not at the level of source of expenditure. Our results show that the subcomponents of health expenditure exhibit different patterns of behaviour at both cointegration and unit root stages once policy shifts or structural breaks are allowed in the empirical analysis. When the possibility of structural break is allowed we find a significant long‐run relationship between subcomponents of aggregate health expenditure and GDP that is not observed when break is not allowed. The underlying reasons for the occurrence of breaks and policy lessons are discussed subsequently.     

Are business cycles stationary fluctuations around a deterministic trend? Empirical evidence from 79 developing countries

There is a large literature that tests the univariate time series properties of the real output series following the seminal work of Nelson and Plosser (1982). Whether or not real output is characterized by a unit root process has important implications. A unit root in real output, for instance, is inconsistent with the notion that business cycles are stationary fluctuations around a deterministic trend. In this paper, we investigate the univariate time series properties of real output for 79 developing countries using the conventional augmented Dickey and Fuller (1979) unit root test, the Zivot and Andrews’ (1992) one structural break unit root test, and the Lumsdaine and Papell (1997) two structural breaks unit root test. Our main finding is that, for 40 countries, real output is stationary around a trend. This indicates that business cycles are stationary fluctuations around a deterministic trend for only 51% of the developing countries in our sample.     

Housing and the Great Depression

This article considers the structural stability of the relationship between the real housing price and real GDP per capita for an annual sample that includes the Great Depression. We test for structural change in parameter values using a sample of annual US data from 1890 to 1952. The article examines the long-run and short-run dynamic relationships between the real housing price and real GDP per capita to determine whether these relationships experienced structural change over the sample period. We find that temporal Granger causality exists between these two variables only for subsamples that include the Great Depression. For the other subsample periods as well as for the entire sample period, no relationship exists between these variables.     

Remittances and GDP in Jamaica: An ARDL Bounds Testing Approach to Cointegration

Similar to other developing nations, Jamaica’s remittances, specifically inflows, are an important source of income support and foreign exchange earnings. Anecdotally, much has been said about the relationship between remittances and GDP in this country. Yet, less has been established using rigorous statistical inference. We test for unit roots with structural breaks and use the autoregressive distributed lag (ARDL) approach to cointegration to help fill this lacuna in the literature on Jamaica. Using annual data for the 1976–2014 period, we examine the relationship between GDP and remittances, both measured in constant 2010 US dollar terms, as we control for the common determinants of economic growth. The main finding is that GDP and remittances are cointegrated relationship wherein they both reinforce each other positively. This finding is statistically robust as the ARDL models have well-behaved errors and parameters that are generally stable over the period. We discuss policy implications of this finding.     

Revisiting the environmental kuznets curve hypothesis: evidence from the ASEAN-5 countries with structural breaks

This paper tests if the Environmental Kuznets Curve (EKC) hypothesis exists for ASEAN-5 countries in an annual sample data that covers 1971–2013, by utilizing Auto Regressive Distributed Lag (ARDL) methodology. The empirical findings give support for the EKC hypothesis for Thailand only, after considering the structural breaks. Furthermore, the paper tests the EKC hypothesis for a panel data of the ASEAN-5 by adopting the Pooled Mean Group (PMG) methodology. The results show that the long-run estimates provide no evidence for the EKC hypothesis. Finally, the paper examines the causality between the CO₂ emissions and GDP. For individual countries, bidirectional causality was found in the case of Thailand and Malaysia, plus unidirectional causality running from GDP and squared GDP to CO₂ emissions was found for Indonesia, but a unidirectional causality running from CO₂ emissions to GDP and squared GDP was found for the Philippines, however, no causality effect was found for Singapore. Furthermore, the pairwise Dumitrescu and Hurlin Panel Causality test show a bidirectional effect between CO₂ emissions and both GDP in addition to squared GDP.     

Trend Breaks and the Unit-Root Hypothesis For Newly Industrializing and Newly Exporting Countries*

We examine trend breaks and unit roots in aggregate and per capita real GDP for mine newly industrializing (NIC) and newly exporting (NEC) countries in east and southeast Asia. In 15 of the 18 cases, we reject the unit-root hypothesis in favor of trend stationarity with breaks. Our findings allow us to trace the growth paths of these NICs and NECs. While the shifts are due to both external and internal factors, most of the breaks are country specific and can be partly attributed to changes in government policies.     

THE BEHAVIOR OF U.S. PUBLIC DEBT AND DEFICITS DURING THE GLOBAL FINANCIAL CRISIS

In this paper we test the sustainability of U.S. public debt for the period 1916–2012 by analyzing how the primary surplus to gross domestic product (GDP) responds to changes in the debt to GDP ratio in a time‐varying parameter model. Further, we determine the stationarity property of the debt/GDP ratio while accommodating possible breaks in the data caused by wars and economic crisis under both the null and alternative hypotheses of an endogenous unit root test. The results show that the U.S. public debt was sustainable until 2005 when the primary surplus to GDP reacted negatively to the debt/income ratio. This is further exacerbated during the global financial crisis when primary surpluses continued to fall with increased debt, thus jeopardizing the sustainability of fiscal policy. While the stationarity test shows that the U.S. fiscal debt/GDP ratio is sustainable, it fails to highlight the risk that its debt policy has been becoming unsustainable in recent years.
