Revisiting Purchasing Power Parity in OECD

This study revisits Purchasing Power Parity theory (PPP) in the 34 OECD countries during January 1994–August 2013. We use a new panel stationary test with both sharp breaks and smooth shifts, a novel approach to panel unit-root testing, proposed by Bahmani–Oskooee et al. (2014). The results indicate that the PPP holds in half of the 34 OECD countries. These results indicate the importance of proper modelling of both sharp breaks and smooth shifts in real effective exchange rate series of OECD countries.     

Is there a unit root in the inflation rate? New evidence from panel data models with multiple structural breaks

In this article, we examine whether or not the inflation rate for 17 OECD countries can be modelled as a stationary process. We find that (1) conventional univariate unit root tests without any structural breaks generally reveal that the inflation rate contains a unit root; (2) the KPSS univariate test with multiple structural breaks reveals that for 10 out of 17 countries inflation is stationary; and (3) the KPSS panel unit root test reveals strong evidence for stationarity of the inflation rate for panels consisting of countries which were declared nonstationary by univariate tests.     

International migration,foreign direct investment,and development stage in developing economies

The existing empirical results on the relationship between FDI and migration are rather mixed. This study reevaluates, both theoretically and empirically, how inward FDI relates to emigration in developing countries. Our model illustrates that the relationship between inward FDI and emigration flows depends on the development stage of a developing country, that is, there is a positive association between inward FDI and emigration flows for relatively less‐developed countries but a negative association between these two variables for relatively developed countries. We confirm the empirical validity of our model prediction using the panel data of 21 OECD and 51 non‐OECD countries during the period from 2003 to 2012. Our results argue that as economic development proceeds in a developing country, the home effect of inward FDI associated with intensified labor demand would dominate the linkage effect that induces the brain drain problem through enhancing the socioeconomic ties with migrant networks.     

Foreign Direct Investment Determinants in OECD and Developing Countries

In this paper we examine the foreign direct investment (FDI) inflow determinants in 24 Organisation for Economic Co‐operation and Development (OECD) and 22 developing (non‐OECD) countries over 1980–2012, using the standard fixed effects as well as a dynamic panel approach. The most robust finding is that lagged FDI, market size, gross capital formation and corporate taxation significantly affect FDI inflows in OECD countries. We also examine a group of developing countries, taking into consideration the increased share of world FDI inflows that developing countries have attracted, and compare the results. In this case, lagged FDI, market size, labor cost and institutional variables provide the most robust results. The empirical results have important policy implications indicating the factors that host economies should emphasize in order to attract FDI inflows.     

Foreign investments in real estate,economic growth and property prices: evidence from OECD countries

The last two decades have witnessed a growth in foreign direct investments (FDI) in the real estate sector in most of the Organization for Economic Co-Operation and Development (OECD) countries. It is argued that FDI in the real estate sector may improve economic growth in recipient economies. On the other hand, property prices have increased considerably in OECD countries in recent years and some argue that FDI in real estate is one of the driving forces of high property prices in these countries. The purpose of this study is to analyze the interrelationship between FDI in the real estate sector, economic growth, and property prices while controlling for interest rate and inflation. We use observations from a set of OECD countries for the period between 1995 and 2008. The dynamic interrelationship is analyzed by applying a panel cointegration technique. Our empirical results show that FDI in real estate do not cause property price appreciations and also do not contribute to economic growth in OECD countries in the short run and the long run.     

Are OECD consumption–income ratios stationary after all?

This paper investigates the stochastic properties of the consumption–income ratio for a sample of 23 OECD countries over the period 1960–2005. For that purpose, we employ a battery of recently developed panel unit root and stationarity tests. Our findings from panel unit root tests which do not control for structural breaks appear in line with those from previous studies since they are clearly supportive of the unit root hypothesis. In stark contrast stand the results obtained from the application of a panel stationarity test with multiple breaks, which support the existence of regime-wise stationarity in OECD consumption–income ratios once we control for cross-sectional dependence through bootstrap methods. These findings are reinforced by the median-unbiased estimates of half-lives obtained from impulse-response functions which are found to be finite for the 23 OECD countries.     

Determinants of foreign direct investment of OECD countries 1991–2001

It is the objective of this paper to identify the determinants that led to the increase in worldwide foreign direct investment during the 1990s. The paper also addresses the question of whether these factors influenced exports differently. Therefore, using data from 22 countries reporting to the OECD, gravity models for bilateral FDI stocks/flows and exports are estimated, first in a cross-section setting for 1999 and then as a panel data set for the period 1991–2001. In order to control for EU-specific effects, a distinction is made between intra-EU25 observations and observations outside the EU25 area. Regressions are repeated with exports as a dependent variable in order to elaborate how far determinants of trade flows are identical or how far they differ. In the panel context, the results show that a change in total market size is an important aspect that leads both FDI and exports in the same direction. Only exports are significantly influenced by relative market size. Stock market booms boost FDI but not exports. Political indicators and exchange rate changes suggest that exports are demand-driven while FDI is supply-driven. Overall, FDI and exports tended to flow relatively less abundantly to distant countries than to nearby countries over the period under consideration. This supports the idea of a complementary relationship between investment and trade. However, this trend is reversed for exports within the EU25 area.     

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.      

Response of inflation to shocks: New evidence from Sub-Saharan African countries

In this paper, we investigate whether or not the inflation rate of 17 Sub-Saharan African countries can be modelled as a stationary process. We achieve this goal through using univariate and panel stationarity tests for data over the period 1966 to 2002. We use the Kwiatkowski, Phillips, Schmidt and Shin (KPSS, 1992) univariate test and allow for multiple structural breaks. We find that except for Burkina Faso, Burundi and Gambia, the inflation rate is stationary for the rest of the 14 countries. We then apply the panel version of the KPSS test, developed by Carrion-i-Silvestre et al. (2005), which accounts for multiple structural breaks. We find strong evidence of panel stationarity of the inflation rate. However, for a panel consisting of Burkina Faso, Burundi and Gambia, we could not find evidence that the inflation rate is stationary.     

HYSTERESIS IN UNEMPLOYMENT REVISITED: EVIDENCE FROM PANEL LM UNIT ROOT TESTS WITH HETEROGENEOUS STRUCTURAL BREAKS

This paper applies the panel LM unit root tests with heterogeneous structural breaks in level by Im  et al. ( Oxford Bulletin of Economics and Statistics , 67 (2005), pp. 393–419) to re-examine the validity of hysteresis in the unemployment rates of 19 OECD countries. Our empirical findings are favourable to the stationarity of the unemployment rates, i.e., the unemployment hysteresis hypothesis is strongly rejected. Our results suggest that shocks to unemployment rates are temporary and soon converge when we control for breaks. A major policy implication of the study is that a fiscal or monetary stabilization policy would not have permanent effects on the unemployment rates of the 19 OECD countries.     

Foreign direct investment in OECD countries: a special focus in the case of Greece

Foreign Direct Investment (FDI) is considered as an important instrument for economic development all over the world. The aim of this paper is to examine the FDI inflows determinants for 24 OECD countries. To this end we employ annual data from 1980 to 2012 for a series of potential FDI determinants that have been identified as the most important by the relevant literature. Our empirical strategy employs both the standard fixed effects panel as well as a dynamic panel approach. The empirical findings highlight the importance of market size, trade openness, unit labor cost, schooling, taxation, gross capital formation, institutional variables, and ROA/ROE as significant FDI determinants. In the case of the dynamic panel model those FDI inflows determinants are not uniform for all country groups. Additionally, the results indicate that corporate tax rates clearly affect FDI attractiveness. This finding is robust when testing different countries subgroups. The present study has important policy implications indicating the factors that host economies should place emphasis on in order to attract FDI inflows. Policy makers should not only pay attention to the corporate tax rate level but they should also design a simple, stable and transparent taxation system that minimizes the relevant business risk.     

International trade,economic growth and intellectual property rights: A panel data study of developed and developing countries

This paper examines the role of high-technology trade, IPRs and FDI in determining a country's rate of innovation and economic growth. The empirical analysis is conducted using a unique panel data set of 47 developed and developing countries from 1970 to 1990. The results suggest that: (1) high-technology imports are relevant in explaining domestic innovation both in developed and developing countries; (2) foreign technology has a stronger impact on per capita GDP growth than domestic technology; (3) IPRs affect the innovation rate, but this impact is more significant for developed countries; (4) the results regarding FDI are inconclusive.     

Long-run homogeneity of labour demand. Panel evidence from OECD countries

This study makes an attempt to examine the long-run relationship between the key labour market parameters of employment, aggregate output, real product wages and labour-augmenting technical progress for a sample of 21?OECD countries covering the period from 1970 to 2000. A new panel error correction technique is applied, which allows one to constrain the long-run coefficients to be identical across the countries while letting the short-run coefficients which govern the dynamics and the error variances differ freely, respectively. Thus, this estimation approach assumes that institutional and cultural differences, albeit causing short-term deviations of labour demand behaviour across countries, leave the long-run structure of the labour markets unaffected. That is to say, the long-run equilibrium relationship between the key labour market variables is taken to be similar across the OECD economies. The empirical analysis shows that the long-run relationship between the key labour market parameters is equal across the OECD countries. However, adjustment speed of actual employment to the equilibrium is much higher in countries with flexible labour markets, such as the USA and UK, than in countries with rigid labour markets, such as Germany and Austria.     

The pattern of international patenting and technology diffusion

The article focuses on the impact of R&D expenditure on labour productivity using international patent applications as a technology diffusion indicator. Considering the relationship between research and productivity, the pattern of international patenting reflects the channel between the source and the destination of transferred technology. Accounting for nonstationarity and cointegration, I find that patent-related foreign R&D spillovers are present for a panel of 18 OECD countries. Moreover, nonG7 OECD countries benefit more from foreign rather than domestic R&D activities. Estimates also show that there is no significant spillover effect from bilateral trade, but confirm the impact of FDI on domestic labour productivity.     

Stochastic convergence of per capita carbon dioxide emissions and multiple structural breaks in OECD countries

This research applies an innovative panel data stationarity testing procedure developed by Carrion-i-Silvestre et al. [Carrion-i-Silvestre, J.L., Barrio-Castro, T.D. and Lopez-Bazo, E., 2005. Breaking the panels: An application to the GDP per capita, Econometrics Journal 8, 159–175.], which has the advantage of recognizing multiple structural breaks and the presence of cross-section dependence in order to re-investigate the hypothesis that per capita carbon dioxide (CO₂) emissions stochastically converge for 21 OECD countries from 1950 to 2002. Remarkably, the evidence clearly indicates that the panel dataset of relative per capita CO₂ emissions is stationary after the structural breaks and cross-sectional dependence are introduced into the model. These findings offer strong policy implications for governments, regardless of whether they are in “convergent group” or “divergent group” countries. We also find that the structural breaks in the 1960s and over the 1970–1982 period are associated with time periods of fossil fuel becoming the main source of productivity, higher oil prices, and the development of nuclear power.

Foreign Direct Investment Outflows and Business‐cycle Fluctuations*

This paper investigates business‐cycle effects for a country’s foreign direct investment (FDI) outflows. Ordinary least squares and panel regressions show that volatility in economic growth has a negative and significant impact on FDI outflows. Furthermore, we find different types of shocks have asymmetric impacts on FDI outflows. In other words, fluctuations of the same magnitude in a boom and a recession have different effects on FDI outflows. This relationship is more evident in OECD countries. We also include exchange rate volatility, lagged business‐cycle measure, and control for potential endogeneity problems as robustness checks. Our findings are robust across different specifications.     

Social security expenditure and GDP in OECD countries: A cointegrated panel analysis

Abstract

Using panel data unit root tests and panel cointegration tests, as well as estimation techniques appropriate for heterogeneous panels such as the full modified OLS, this paper re-examines the long-run co-movement and the causal relationship between GDP and social security expenditure in a bivariate model, employing data on 25 OECD countries from 1980 to 2001. Our cointegration test results show strong evidence in favour of the existence of a long-run equilibrium cointegrating relationship between GDP and social security expenditure after allowing for a heterogeneous country effect. Regarding the panel-based error correction model, we find that GDP and social security expenditure lack short-run causality, but reveal the existence of long-run bidirectional causality. This shows that, in the long run, economic growth must be based on a social welfare policy that should be carried out, and economic growth can facilitate contiguous development in a social welfare policy. Lastly, we also provide evidence to support that social security expenditure can affect growth through the savings and human capital accumulation in OECD countries.     

The impact of endogenous tax treaties on foreign direct investment: theory and evidence

Abstract .  This paper investigates the effect of tax treaties on bilateral stocks of outward FDI. For this purpose we employ a numerically solvable general equilibrium model of trade and multinational firms to study the impact of tax treaties on both welfare and outward FDI. The model indicates under which factor endowment configurations countries gain in welfare when implementing a tax treaty. This motivates an empirical specification of the endogenous selection into implementing new tax treaties. Using data of bilateral OECD outward FDI between 1985 and 2000, we find a significant negative impact of newly implemented tax treaties on outward FDI stocks.     

Testing for unemployment hysteresis in nonlinear heterogeneous panels: International evidence

Nonlinear behavior of unemployment is well documented in the literature, and thus linear unit root tests may not be appropriate in this case. This paper tests for hysteresis of unemployment for 29 OECD countries through the use of a new nonlinear panel unit root test developed by Ucar and Omay (2009). The test examines the joint null hypothesis of linearity and a unit root against the alternative hypothesis of nonlinear stationarity. Large power gains are achieved by both combining cross-sectional information with nonlinearities in the data. In addition, after the unit root null being rejected, we use a sequential panel selection method suggested by Chortareas and Kapetanios (2009) to classify the whole panel into a group of stationary countries and a group of non-stationary countries. The empirical findings show that the nonlinear panel test gives strong evidence in favor of the natural rate hypothesis of unemployment for 23 of 29 OECD countries, in contrast to those obtained by Chang's (2002) linear panel test that 17 countries display evidence of stationary unemployment.
