Estimation of SEs for heteroscedastic and cross-sectionally correlated data

This study develops SE estimators for heteroscedastic and cross-sectionally correlated data. The new estimators are a cross-sectional version of the White and Domowitz (1984 White, H and Domowitz, I. 1984. Nonlinear regression with dependent observations. Econometrica, 52: 143–61. [Crossref], [Web of Science ®] , [Google Scholar]) and Newey and West (1987 Newey, W and West, K. 1987. A simple positive semi-definite, heteroscedasticity and autocorrelation consistent covariance matrix. Econometrica, 55: 703–8. [Crossref], [Web of Science ®] , [Google Scholar]) estimators, and therefore, consistent in the presence of heteroscedasticity and cross correlation of unknown form. Unlike the estimators in the literature, these estimators can control for cross correlation even for single-period cross-sectional data.     

Nonlinearity in real exchange rates: an approach with disaggregated data and a new linearity test

Employing disaggregated real exchange rates from nine European counties in 16 goods categories, we assess in this study the nonlinearity in the real exchange rates. Surprisingly, we find evidence for nonlinearity in only four (10) out of 143 series with the linearity test proposed by Harvey et al. (2008 Harvey, D. I., Leybourne, S. J. and Xiao, B. 2008. A powerful test for linearity when the order of integration is unknown. Studies in Nonlinear Dynamics and Econometrics, 12 Art 8[Web of Science ®] , [Google Scholar]) at the 5% (10%) significance level. This result differs greatly from those of Juvenal and Taylor (2008 Juvenal, L. and Taylor, M. P. 2008. Threshold adjustment of deviations from the law of one price. Studies in Nonlinear Dynamics and Econometrics, 12 Art 8[Web of Science ®] , [Google Scholar]), Imbs et al. (2003 Imbs, J., Mumtaz, H., Raven, M. O. and Rey, H. 2003. Nonlinearities and real exchange rate dynamics. Journal of the European Economic Association, 1: 639–49. [Crossref] , [Google Scholar]), Sarno et al. (2004 Sarno, L., Taylor, M. P. and Chowdhury, I. 2004. Nonlinear dynamics in deviations from the law of one price: a broad-based empirical study. Journal of International Money and Finance, 23: 1–25. [Crossref], [Web of Science ®] , [Google Scholar]) and Berka (2009 Berka, M. 2009. “Non-linear adjustment in law of one price deviations and physical characteristic of good”. In Review of International Economics Vol. 17, 51–73.  [Google Scholar]), who report ample evidence for nonlinearity for the same or similarly disaggregated real exchange rate datasets.     

What (if any) are the returns to computer use?

Using North American data, we revisit the question first broached by Krueger (1993 Krueger, AB. 1993. How computers have changed the wage structure: evidence from microdata. Quarterly Journal of Economics, 108: 33–60. [Crossref], [Web of Science ®] , [Google Scholar]) and re-examined by DiNardo and Pischke (1997 DiNardo, JE and Pischke, J-S. 1997. The returns to computer use revisited: have pencils changed the wage structure too?. Quarterly Journal of Economics, 112: 291–303. [Crossref], [Web of Science ®] , [Google Scholar]) of whether there exists a real wage differential associated with computer use. Employing a mixed effects model with matched employer–employee data to correct for the fact that workers and workplaces that use computers are self-selected, we find that computer users enjoy an almost 4% wage premium over nonusers. Failure to correct for worker and workplace selection effect leads to a more than twofold overestimate of this premium.     

Ownership herding and informational herding

This article takes as its point of departure the herding model of Bikhchandani et al. (1992 Bikhchandani, S., Hirshleifer, D. and Welch, I. 1992. A theory of fads, fashion, custom, and cultural change as informational cascades. Journal of Political Economy, 100: 992–1026. [Crossref], [Web of Science ®] , [Google Scholar]). We extend earlier experimental evidence to distinguish between informational herding, as in the model, and ownership herding, an alternative explanation for observed behaviour.     

Purchasing power parity for G-7 countries: panel SURADF tests

In this study, the panel Seemingly Unrelated Regressions Augmented Dickey–Fuller (SURADF) tests advanced by Breuer et al. (2001 Breuer, J. B., McNown, R. and Wallace, M. S. 2001. Misleading inferences from panel unit-root tests with an illustration from purchasing power parity. Review of International Economics, 9: 482–93. [Crossref] , [Google Scholar]) are used to test the validity of Purchasing Power Parity (PPP) for G-7 countries over the period 1980M1 to 2008M5. The empirical results from several panel-based unit root tests indicate that PPP does not hold for G-7 countries under study; however, Breuer et al.'s (2001 Breuer, J. B., McNown, R. and Wallace, M. S. 2001. Misleading inferences from panel unit-root tests with an illustration from purchasing power parity. Review of International Economics, 9: 482–93. [Crossref] , [Google Scholar]) panel SURADF tests unequivocally indicate that PPP is valid for half of the G-7 countries.     

Globalization and the effects of changes in functional income distribution on aggregate demand in Germany

Germany has experienced a period of extreme nominal and real wage moderation since the mid‐1990s. Contrary to the expectations of liberal economists, this has failed to improve Germany’s mediocre economic performance. However, Germany is now running substantial current account surpluses. One possible explanation for Germany’s disappointing performance is found in Kaleckian theory, which highlights that the domestic demand effect of a decline in the wage share will typically be contractionary, whereas net exports will increase (Blecker 1989 Blecker, R. 1989. International competition, income distribution and economic growth. Cambridge Journal of Economics, 13: 395–412. [Web of Science ®] [Google Scholar]). The size of the foreign demand effect will critically depend on the degree of openness of the economy. This paper aims at estimating empirically the demand side of a Bhaduri and Marglin (1990 Bhaduri, A. and Marglin, S. 1990. Unemployment and the real wage: The economic basis for contesting political ideologies. Cambridge Journal of Economics, 14: 375–93. [Crossref], [Web of Science ®] [Google Scholar]) type model for Germany. The paper builds on the estimation strategy of Stockhammer, Onaran, and Ederer (2009 Stockhammer, E., Onaran, Ö. and Ederer, S. 2009. Functional income distribution and aggregate demand in the Euro area. Cambridge Journal of Economics, 33(1): 139–59. [Crossref], [Web of Science ®] [Google Scholar]) and Hein and Vogel (2008 Hein, E. and Vogel, L. 2008. Distribution and growth reconsidered – empirical results for six OECD countries. Cambridge Journal of Economics, 32: 479–511. [Crossref], [Web of Science ®] [Google Scholar], 2009 Hein, E. and Vogel, L. 2009. Distribution and growth in France and Germany – single equation estimations and model simulations based on the Bhaduri/Marglin‐model. Review of Political Economy, 21(2): 245–72. [Taylor & Francis Online] [Google Scholar]). The main contribution lies in a careful analysis of the effects of globalization. Since Germany is a large open economy by now it is a particularly interesting case study.     

Unit roots and purchasing power parity: another kick at the can

Lopez et al. (2005 Lopez, C, Murray, C and Papell, D. 2005. State of the art unit root tests and purchasing power parity. Journal of Money, Credit and Banking, 37: 361–9. [Crossref], [Web of Science ®] , [Google Scholar]) demonstrated that single-equation unit-root tests cannot provide conclusive evidence of whether real exchange rates are stationary because inference depends critically on the lag-lengths used to construct the test statistics, a result reinforced by a recent work by Sweeney (2006 Sweeney, D. 2006. Mean reversion in nominal G-10 exchange rates. Journal of Financial and Quantitative Analysis, 41: 685–708. [Crossref], [Web of Science ®] , [Google Scholar]). The purpose of this article is to revisit the issue, first demonstrating the necessary conditions under which this approach of testing for Purchasing Power Parity (PPP) is appropriate.     

Nonlinear Mean Reversion across National Stock Markets: Evidence from Emerging Asian Markets

This paper seeks empirical evidence of nonlinear mean-reversion in relative national stock price indices for Emerging Asian countries. It is well known that conventional linear unit root tests suffer from low power against the stationary nonlinear alternative. Implementing the nonlinear unit root tests proposed by Kapetanios et al. (2003 Kapetanios, G., Shin, Y. and Snell, A. 2003. Testing for a unit root in the nonlinear STAR framework. Journal of Econometrics, 112: 359–379. [Crossref], [Web of Science ®] , [Google Scholar]) and Cerrato et al. (2009 Cerrato, M., de Peretti, C., Larsson, R. and Sarantis, N. 2009. “A nonlinear panel unit root test under cross section dependence”. Working Papers 28, Department of Economics, University of Glasgow [Google Scholar]) for the relative stock prices of Emerging Asian markets, we find strong evidence of nonlinear mean reversion, whereas linear tests fail to reject the unit root null for most cases. We also report some evidence that stock markets in China and Taiwan are highly localized.     

Towards solving the PPP puzzle: evidence from 113 countries

Several different approaches have been followed by researchers to test the validity of Purchasing Power Parity (PPP). Since the introduction of the unit-root tests, researchers have applied a battery of these tests to determine whether the real exchange rates are stationary. If the answer is in the affirmative, PPP is validated. While application of the standard augmented Dickey–Fuller test has not provided much support for PPP, a test that incorporates nonlinearity in the rates has. Under both tests, however, the null of nonstationary is tested against the alternative of stationarity. In this article, when we switch the null with the alternative and apply Kwiatkowski et al. (1992 Kwiatkowski, D, Phillips, PCB, Schmidt, P and Shin, Y. 1992. Testing the null hypothesis of stationarity against the alternative of a unit root. Journal of Econometrics, 54: 159–78. [Crossref], [Web of Science ®] , [Google Scholar]) test, we provide relatively more support for the theory, getting closer and closer towards solving the PPP puzzle.     

Structural changes and regional disparity in China's inflation: a revisit

The study re-examined the time series properties and regional disparities in Chinese inflation by extending the work of Chong, Zhang, and Feng (2011 Chong, Tai-Leeung, Terence, Ning Zhang and Feng, Qu. 2011. Structural Changes and Regional Disparity in China's Inflation. Economics Bulletien, 31(1): 572–583.  [Google Scholar]). For this purpose we employed the Lagrange Multiplier (LM) unit root test with one structural break and two structural breaks suggested by Lee and Strazicich (2003 Lee, Junsoo, Mark, C. and Strazicich. 2003. Minimum LM Unit Root Test with Two Structural Breaks. Review of Economics and Statistics, 85(4): 1082–1089. [Crossref], [Web of Science ®] , [Google Scholar], 2004 Lee, J. and Strazicich, M. 2004. Minimum LM unit root test with one structural break. Working Paper 04–17, Boone, North Carolina: Department of Economics, Appalachian State University.  [Google Scholar]) and a recently developed ADF type unit root test with two structural breaks of Narayan and Popp (2010 Narayan, Paresh Kumar and Stephan Popp. 2010. A New Unit root test with Two Structural Breaks in Level and Slope at Unknown Time. Journal of Applied Statistics, 37(9): 1425–1438. [Taylor & Francis Online], [Web of Science ®] , [Google Scholar]). We found that national, urban and rural series of the overall inflation series, clothing, and food, national series of education and residence and the rural series of residence and education are stationary. We also found regional disparity in Chinese inflation, but the disparities existed only in education inflation series.     

Convergence in household credit demand across euro area countries: evidence from panel data

This article contributes to the literature on the convergence of financial systems in the euro area by estimating household credit demand in individual countries. Using the ARDL framework advocated notably by Pesaran et al. (1999 Pesaran, MH, Shin, Y and Smith, RP. 1999. Pooled mean group estimation of dynamic heterogeneous panels. Journal of the American Statistical Association, 94: 621–34. [Taylor & Francis Online], [Web of Science ®] , [Google Scholar]), the article provides evidence on the convergence of long-run credit demand determinants (interest rates, investment and house prices) in the largest euro area countries, while short run-dynamics remain heterogenous across countries. The article also demonstrates that the equation uncovers demand rather than supply behaviour.     

Does debt market timing increase firm value?

Survey evidence indicates that firm managers try to time debt markets when choosing the maturity of new debt issues, but we do not know whether these strategies increase firm value. This research examines differences in value across nontimers and timers, where timers are defined as firms that follow either a naïve strategy of choosing long-term debt when the term premium is low or a strategy from Baker et al. (2003 Baker, M, Greenwood, R and Wurgler, J. 2003. The maturity of debt issues and predictable variation in bond returns. Journal of Financial Economics, 70: 261–91. [Crossref], [Web of Science ®] , [Google Scholar]) based on the predictability of future excess bond returns. After controlling for various determinants of firm value, the research finds no differences in value across timers and nontimers. It also documents that the timing strategies do not increase firm value and do not affect announcement effects of long-term debt offerings. The results suggest that corporate debt markets are efficient and well integrated with equity markets.     

Another look at the spending response to the 2001 income tax rebates

This article revisits the spending response to the 2001 US tax rebates by focussing on two key aspects of how tax policy researchers use the Consumer Expenditure Survey (CEX). These two attributes, which are often overlooked, are as follows: the measures used for consumption and the ‘outlier’ criteria applied to the data. First, I reproduce the results in Johnson et al. (2006 Johnson, DS, Parker, JA and Souleles, NS. 2006. Household expenditure and the income tax rebates of 2001. American Economic Review, 96: 1589–610. [Crossref], [Web of Science ®] , [Google Scholar]), which (using the CEX) concluded that households immediately spent 20–40% of their rebates on nondurable consumption goods. Then, I show how making two changes – both of which are relied upon in the literature – affects their results. These adjustments reduce the estimated magnitude of the rebate's impact by as much as 100%.     

Purchasing power parity for East-Asia countries: further evidence based on panel stationary test with multiple structural breaks

In this article, we re-investigate the validity of Purchasing Power Parity (PPP) for a sample of 10 East-Asia countries over the period of January 1987 to June 2005, using a recently developed econometric technique of the panel stationary test with multiple structural breaks, proposed by Carrion-i-Silvestre et al. (2005 Carrion-i-Silvestre, JL, Del Barrio, T and López-Bazo, E. 2005. Breaking the panels: an application to the GDP per capita. Econometrics Journal, 8: 159–75. [Crossref], [Web of Science ®] , [Google Scholar]). This test considers multiple structural breaks positioned at different unknown dates and a different number of breaks for each individual. Empirical evidence shows that the PPP holds true for half of 10 East-Asia countries during the research period. Our results have important policy implications for these 10 East-Asia countries under study.     

Immiserizing Growth and the Metzler Paradox in the Ricardian Model

Conditions for the occurrence of immiserizing growth and the Metzler paradox are analysed in the Ricardian model when consumers in the foreign country have Leontief preferences while consumers in the home country have Cobb-Douglas preferences. By using specific functional forms, the conditions for the occurrence of the two paradoxes are defined in terms of the exogenous parameters of the model rather than endogenous variables such as the foreign import demand elasticity in the conditions of Bhagwati (1958) Bhagwati, J. N. 1958. Immiserizing growth: a geometrical note. Review of Economic Studies, 25: 201–205. [Crossref], [Web of Science ®] , [Google Scholar] and Metzler (1949a Metzler, L. A. 1949a. Tariffs, the terms of trade and the distribution of national income. Journal of Political Economy, 57: 1–29. [Crossref], [Web of Science ®] , [Google Scholar], b Metzler, L. A. 1949b. Tariffs, international demand, and domestic prices. Journal of Political Economy, 57: 345–351. [Crossref], [Web of Science ®] , [Google Scholar]). It is shown that the simultaneous occurrence of both paradoxical results is possible for some parameter values.     

Deterministic and stochastic trends in the time series models: a guide for the applied economist

Applied economists working with time series data face a dilemma in selecting between models with deterministic and stochastic trends. While models with deterministic trends are widely used, models with stochastic trends are not so well known. In an influential paper Harvey (1997 Harvey, AC. 1997. Trends, cycles and autoregression. Economic Journal, 107: 192–201. [Crossref] , [Google Scholar]) strongly advocates a structural time series approach with stochastic trends in place of the widely used autoregressive models based on unit root tests and cointegration techniques. Therefore, it is important to understand their relative merits. This article suggests that both methodologies are useful and they may perform differently in different models. This article provides a few guidelines to the applied economists to understand these alternative methods.     

Financial development and economic growth nexus: a time-series evidence from India

This study examines the relationship between financial development and economic growth in India for the period 1951–52 to 1995–96. The long-run equilibrium and short-run dynamic models are estimated using financial interrelations ratio and new issue ratio as the measures of financial development, a la Goldsmith (1969 Goldsmith, RW. 1969. Financial Structure and Development, New Haven: Yale University Press.  [Google Scholar]). The Johansen (1991 Johansen, S. 1991. Estimation and hypothesis testing of cointegration vectors in Gaussian vector autoregressive models’. Econometrica, 59: 1551–80. [Crossref], [Web of Science ®] , [Google Scholar]) estimator rejects the null of zero cointegrating vector and shows the presence of long-run equilibrium relationship between financial development and economic growth. The error correction model, impulse response and variance decomposition analyses (Sims, 1980 Sims, CA. 1980. Macroeconomics and reality. Econometrica, 48: 1–48. [Crossref], [Web of Science ®] , [Google Scholar]), and the Toda and Yamamoto (1995 Toda, HY and Yamamoto, T. 1995. Statistical inference in vector autoregressions with possibly integrated processes. Journal of Econometrics, 66: 225–50. [Crossref], [Web of Science ®] , [Google Scholar]) estimator show the presence of bidirectional Granger-causality between financial development and economic growth. The presence of bidirectional Granger-causality suggested by these estimators points towards the possible problem of endogeneity and simultaneity bias in the growth models that examine the contemporaneous effect of financial development on economic growth. The economic reforms that started since July 1991 emphasized on the liberalization and development of financial sector to supplement the efforts aimed at achieving high economic growth in India.     

Price transmission,foreign exchange rate risks and global diversification of ADRs

The purposes of this article are to reinvestigate how returns of major American depository receipts (ADRs) from different countries are related to the underlying stock returns and to identify the determinants of ADR risk premiums. We use different types of error-correcting terms in vector error correction models to examine information flows between ADRs and the underlying foreign stocks. General method of moments estimation of conditional international asset pricing model of Dumas and Solnik (1995 Dumas, B and Solnik, B. 1995. The world price of foreign exchange risk. Journal of Finance, 50: 445–79. [Crossref], [Web of Science ®] , [Google Scholar]) is applied to investigate ADR return premiums. We find that stock returns are more affected by disequilibrium between ADR and stock prices in an inefficient way. For US investors, foreign exchange rate risk premiums and world market risk premium (beyond US index) are priced in ADRs returns ex ante. Surprisingly, it is shown that the exchange rate of New Taiwan dollar and the interest rates of Brazil and Taiwan play important roles in determining ADR risk premiums across countries.     

Comparisons of robust tests for shifts in trend with an application to trend deviations of real exchange rates in the long run

We study the finite sample properties of tests for structural changes in the trend function of a time series that do not require knowledge of the degree of persistence in the noise component. The tests of interest are the quasi-Feasible Generalized Least Squares (FGLS) procedure by Perron and Yabu (2009b Perron, P and Yabu, T. 2009b. Testing for shifts in trend with an integrated or stationary noise component. Journal of Business and Economic Statistics, 27: 369–96. [Taylor &; Francis Online], [Web of Science ®] , [Google Scholar]) and the weighted average of the regression t-statistics by Harvey et al. (2009 Harvey, DI, Leybourne, SJ and Taylor, AMR. 2009. Simple, robust, and powerful tests of the breaking trend hypothesis. Econometric Theory, 25: 995–1029. [Crossref], [Web of Science ®] , [Google Scholar]), both of which have the same limit distribution whether the noise component is stationary or has a unit-root. We analyse the finite sample size and power properties of these tests under a variety of Data-Generating Processes (DGPs). The results show that the Perron–Yabu test has greater power overall. With respect to the size, the Harvey–Leybourne–Taylor test exhibits larger size distortions unless a moving-average component is present. Using the Perron and Yabu procedure to test for structural changes in the trend function of long-run real exchange rates with respect to the US dollar indicates that for 17 out of 19 countries, the series have experienced a shift in trend since the late nineteenth century.     

Spanish stock market sensitivity to real interest and inflation rates: an extension of the Stone two-factor model with factors of the Fama and French three-factor model

This study is focussed on estimating the real interest and inflation sensitivity in Spanish market, proposing an extension of the Stone (1974 Stone, BK. 1974. Systematic interest-rate risk in a two-index model of returns. Journal of Financial and Quantitative Analysis, 9: 709–21. [Crossref], [Web of Science ®] , [Google Scholar]) two-factor model and controlling for size and growth of the companies [Fama and French (1993) three-factor model], because of its importance in the stock sensitivity shown by previous literature. I also study the classical explanatory factors of the stock sensitivity: leverage and liquidity level of the firms. The Spanish stock response is similar to the response in other markets, and the ‘size’ is higher than ‘growth’ effect.
