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.     

The payoff and implied pricing kernel in REITs

This article explores the hybrid character (i.e. the resemblance of both stock and bond) of Real Estate Investment Trust (REIT) through the implied pricing kernel behind REITs prices. We use the Empirical Pricing kernel method (Rosenberg and Engle, 2002 Rosenberg, J and Engle, RF. 2002. Empirical pricing kernels. Journal of Financial Economics, 64: 341–72. [Crossref], [Web of Science ®] , [Google Scholar]) to explore their Payoff probability density and extract the implied pricing kernel. To estimate payoff probability density, we use asymmetric GARCH model. Results indicate that implied pricing kernels flatten in all ranges of low rate of returns and decrease exponentially in ranges of high rate of returns. This means the REIT pricing kernel resembles a bond when rate of return is low, and a stock when it is high. The pattern is consistent between 1970 and 2000.     

Modelling the dynamics of EU economic sentiment indicators: an interaction-based approach

This article estimates a simple univariate model of expectation or opinion formation in continuous time adapting a ‘canonical’ stochastic model of collective opinion dynamics (Weidlich and Haag, 1983 Weidlich, W, and Haag, G, 1983. Concepts and Models of a Quantitative Sociology. Berlin: Springer; 1983.[Crossref] , [Google Scholar]; Lux, 1995 Lux, T, 1995. Herd behavior, bubbles and crashes, The Economic Journal 105 (1995), pp. 881–96.[Crossref], [Web of Science ®] , [Google Scholar], 2009a Lux, T, 2009a. Rational forecasts or social opinion dynamics? Identification of interaction effects in a business climate survey, Journal of Economic Behavior and Organization 72 (2009a), pp. 638–55.[Crossref], [Web of Science ®] , [Google Scholar]). This framework is applied to a selected data set on survey-based expectations from the rich EU business and consumer survey database for 12 European countries. The model parameters are estimated through Maximum Likelihood (ML) and numerical solution of the transient probability density functions for the resulting stochastic process. The model's success is assessed with respect to its out-of-sample forecasting performance relative to univariate Time Series (TS) models of the Autoregressive Moving Average model, ARMA(p,?q) and Autoregressive Fractionally Integrated Moving Average, ARFIMA(p,?d,?q) varieties. These tests speak for a slight superiority of the canonical opinion dynamics model over the alternatives in the majority of cases.     

Empirical relevance of the Hillman condition for revealed comparative advantage: 10 stylized facts

The theoretically necessary and sufficient condition for the correspondence between ‘revealed’ comparative advantage and pre-trade relative prices derived by Hillman (1980 Hillman, AL. 1980. Observations on the relation between ‘revealed comparative advantage’ and comparative advantage as indicated by pre-trade relative prices. Weltwirtschaftliches Archiv, 116: 315–21. [Crossref] , [Google Scholar]) is analysed empirically for virtually all countries of the world over an extended period of time. This yields 10 stylized facts, including that (i) violations of the Hillman condition are small as a share of the number of observations, but substantial as a share of the value of world exports, (ii) violations occur relatively frequently in the period 1970–1984 and more rarely in the period 1985–1997 and (iii) violations occur foremost in primary product and natural resource intensive sectors and for countries in Africa, the Middle East, Latin America and Central and Eastern Europe. An additional bonus of verifying the Hillman condition in empirical research is its ability to identify erroneously classified trade flows.     

Testing for threshold cointegration and error correction: evidence in the petroleum futures market

This article examines the existence of threshold cointegration between futures and spot prices for the Brent petroleum market. We then estimate the asymmetric error-correction specification utilizing the Momentum Threshold Autoregressive Consistent (M-TAR-C) approach particularly proposed by Enders and Siklos (2001 Enders, W and Siklos, PL. 2001. Cointegration and threshold adjustment. Journal of Business and Economic Statistics, 19: 166–76. [Taylor & Francis Online], [Web of Science ®] , [Google Scholar]). We find that, for the daily data over 2 January 2001 through 15 October 2006, the petroleum futures prices are cointegrated with the spot prices. This effectively confirms the expectations hypothesis and that asymmetric adjustments for the futures basis towards the long-run value display a negative basis from the long-run equilibrium level more persistently than a positive basis from that level. The empirical result suggests that short-run arbitrages manipulating buy-long (sell-short) futures contracts be profitable when a positive basis is weakening (a negative basis is strengthening).     

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.     

The endogeneity of the natural rate of growth in the regions of Italy

Following León‐Ledesma and Thirlwall (2002a León‐Ledesma, M.A. and Thirlwall, A.P. 2002a. The endogeneity of the natural rate of growth. Cambridge Journal of Economics, 26: 441–59. [Crossref], [Web of Science ®] [Google Scholar]), this paper examines the hypothesis that the natural rate of growth of the Italian regions is endogenous to and positively affected by the actual growth rate. Relying on fixed‐effects and SUR estimation techniques and using annual data for the 20 Italian regions over the period 1977–2003, we find strong support for the endogeneity hypothesis suggesting that faster actual growth raises the natural rate of growth of the average Italian region by about 3–3.7 percentage points. Furthermore, in line with recent findings in the literature, our analysis provides evidence of asymmetries in Okun’s Law. In particular, the asymmetric Okun coefficient in the high‐growth regime turns out to be positive in several cases, implying the unemployment rate may become pro‐cyclical when actual growth rises above a certain threshold rate.     

Confidence and alternative Keynesian methods of asset choice

Abstract

This article elaborates the analysis of asset choice proposed by Keynes and later adopted by Post Keynesians such as Paul Davidson and Hyman Minsky. The article incorporates the essential aspects of the theory of confidence presented in Dequech (1999) Dequech, D. 1999. Expectations and confidence under uncertainty. Journal of Post Keynesian Economics, 21: 415–430. [Taylor & Francis Online], [Web of Science ®] , [Google Scholar], first into an investigation of the relation between confidence and the liquidity premium and then into the broader theory of asset choice. Keynes considered two methods of determining planned investment expenditures: one method is based on the comparison between the marginal efficiency of capital and the interest rate; the other is based on the comparison between the demand price and the supply price of a particular capital good. Both methods can be generalized for asset choice, with investment as a particular case. The article refines and develops these two methods so as to specify more precisely the influence of confidence and speculation on the determination of liquidity premia and hence on the several assets' profitability.     

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.     

Long-run purchasing power parity and asymmetric adjustment in BRICs

The primary aim of this study is an attempt to determine whether the Purchasing Power Parity (PPP) hypothesis holds for those countries that have collectively come to be known as ‘BRICs’, namely, Brazil, Russia, India and China. We use the momentum threshold cointegration tests (advanced by Enders and Siklos, 2001 Enders, W. and Siklos, P. L. 2001. Cointegration and threshold adjustment. Journal of Business Economics and Statistics, 19: 166–76. [Taylor & Francis Online], [Web of Science ®] , [Google Scholar]) to investigate whether any asymmetric adjustment is discernible for BRICs, and show that whilst the Engle–Granger test (which assumes only symmetric adjustment) fails to reveal any cointegrational relationship for BRICs, the threshold cointegration test (with asymmetric adjustment) provides clear evidence of long-run PPP for BRICs, with the notable exception of China. We conclude that asymmetric adjustment of nominal exchange rates plays an important role in eliminating deviations from long-run PPP.     

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%.     

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.     

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.     

A nonparametric revealed preference test of optimal intra-firm resource allocation

The collective rationality hypothesis initiated by Chiappori (1988a Chiappori, PA. 1988a. Rational household labor supply. Econometrica, 56: 63–89. [Crossref], [Web of Science ®] , [Google Scholar]) and applied by Seaton (1997 Seaton, JS. 1997. Neoclassical and collective rationality in household labour supply. Applied Economics Letters, 4: 529–33. [Taylor & Francis Online], [Web of Science ®] , [Google Scholar], 2001) for a two-person household is used to distinguish the organizational behaviour of firms. Firms produce satisfaction to groups as traditional managerial and early behavioural theories of the firm of Williamson, Baumol and Marris suggest, as well as more modern principle agent models. Under certain conditions, intra-firm bargaining leads to a Pareto optimal outcome. What makes this work an important contribution is that it identifies a set of nonvacuous testable restrictions to empirically detect if firm-level data satisfy Pareto optimal behaviour for the main decision makers in the organization.     

Linear and nonlinear Granger-causality between short-term and long-term interest rates during business cycles

This paper is about the causal relationship between short-term and long-term interest rates in the US and Canada. To that end, we apply a linear Granger causality test introduced by Toda and Yamamoto (1995 Toda, H. Y., and T. Yamamoto. 1995. “Statistical Inference in Vector Autoregressions with Possibly Integrated Processes.” Journal of Econometrics 66 (1–2): 225–250. doi:10.1016/0304-4076(94)01616-8.[Crossref], [Web of Science ®] , [Google Scholar]) and the nonlinear Granger causality test of Diks and Panchenko (2006 Diks, C., and V. Panchenko. 2006. “A New Statistic and Practical Guidelines for Nonparametric Granger Causality Testing.” Journal of Economic Dynamics and Control 30 (9–10): 1647–1669. doi:10.1016/j.jedc.2005.08.008.[Crossref], [Web of Science ®] , [Google Scholar]). By combining linear causality effects with the nonlinear ones, it is seen that the most common Granger causality direction between short-term and long-term interest rates is a bidirectional one. We also find that nonlinear Granger causality can be found where no linear causality had been uncovered. Moreover, our findings show that during recent business cycles, the federal funds rate (in the US) and the overnight rate (in Canada) still Granger-cause long-term interest rates significantly.     

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.     

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.     

Long-run validity of purchasing power parity and rank tests for cointegration for Central Asian countries

This study finds that Purchasing Power Parity (PPP) holds in the long-run for Azerbaijan, Kazakhstan and Kyrgyzstan, based on Breitung's (2001 Breitung, J. 2001. Rank tests for nonlinear cointegration. Journal of Business and Economic Statistics, 19: 331–40. [Taylor & Francis Online], [Web of Science ®] , [Google Scholar]) rank tests for cointegration. Results from further analysis indicates that nominal exchange rates and relative prices are nonlinearly interrelated. Trade barriers, transportation costs and government intervention in the pricing system in these countries may have resulted in the establishment of the above-mentioned nonlinear relationship.     

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.     

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.
