Revisiting purchasing power parity for East Asian countries using the rank test for nonlinear cointegration

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.     

Deviations and mean reversion to purchasing power parity in the Asian currency crisis of 1997

This study analyses the process of mean reversion towards purchasing power parity (PPP) for a sample of Asian countries around the 1997 crisis. It is found that appreciation relative to PPP is evident prior to the 1997 crash period. Correction occurs from 1997 onwards, a period marked by extreme movements in exchange rates with both appreciation and depreciation relative to the PPP rate over relatively short periods. The key result of this paper is that although reversion towards PPP is apparent for mean, though not statistically significant, it is clear that there is a substantial, statistically significant change in variance from 1997 onwards. This result has implications both for economic modelling of crash periods and for appropriate choice of statistical tests.     

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.     

Flexible Fourier stationary test in purchasing power parity for African countries

This study applies stationary test with a Fourier function proposed by Enders and Lee (2004 Enders, W and Lee, J. 2004. Testing for a unit root with a nonlinear Fourier function, Tuscaloosa, AL, , USA: Working Paper, Department of Economics, Finance and Legal Studies, University of Alabama.  [Google Scholar], 2009 Enders, W and Lee, J. 2009. The flexible Fourier form and testing for unit roots: an example of the term structure of interest rates, Tuscaloosa, AL, , USA: Working Paper, Department of Economics, Finance and Legal Studies, University of Alabama.  [Google Scholar]) to test the validity of long run Purchasing Power Parity (PPP) to assess the nonstationary properties of the real exchange rate for 20 African countries. We find that our approximation has higher power to detect U shaped breaks and smooth breaks than linear method if the true data generating process of exchange rate is in fact a stationary nonlinear process. We examine the validity of PPP from the nonlinear point of view and provide robust evidence clearly indicate that PPP holds true for almost African countries. Our findings point out their exchange rate adjustment is mean reversion towards PPP equilibrium values in a nonlinear way.     

Cointegration,dynamic structure,and the validity of purchasing power parity in African countries

The purpose of this paper is to test the validity of the purchasing power parity (PPP) in Africa in the context of a multivariate error-correction model. This approach allows for the consideration of long-run elasticities as well as the dynamics of the short-run adjustment of exchange rates to changes in domestic and foreign prices. Monthly data for fourteen African countries are used, and the period examined is 1973:4 through 2007:7 (i.e., 412 observations). Results from long-run cointegration analysis, short-run error correction models, persistence profile analysis and variance decomposition all confirm the validity of PPP in these moderate-to-high inflation countries, where estimates of half-life deviations from PPP are found to be outside the range suggested by Rogoff (1996).     

Market efficiency,purchasing power parity,and the official and parallel markets for foreign currency in Latin America

This paper examines the purchasing power parity (PPP) theory from a long-run perspective in the presence of a parallel or ‘black’ market for U.S. dollars in four Latin American countries, namely Argentina, Brazil, Chile, and Mexico, using monthly data for the recent float. Johansen's full information maximum likelihood multivariate cointegration technique is applied. Recent developments associated with this procedure are considered. First, a formal test developed by Johansen [Econometric Theory 8 (1992) 188, Econometric Theory 11 (1995) 25, Scand. J. Stat. 24 (1997) 433] for the presence of I(2) and I(1) components in a multivariate context is applied along with the estimation of the roots of the companion matrix for the correct determination of the cointegration rank. Second, given that two significant cointegration vectors were found for any country, structural restrictions identifying the long-run relations of interest are specified as proposed by Johansen and Juselius [J. Econometrics 63 (1994) 7] and Johansen [J. Econometrics 69 (1995) 111]. Thus, the joint structure of PPP and long-run informational market efficiency could not be rejected for all countries. Furthermore, estimation of the error correction terms shows that the black market rate adjusts to eliminate any deviation from long-run PPP. Finally, stability tests proposed by Hansen and Johansen [Hansen, H., & Johansen, S. (1993). Recursive estimation in cointegrated VAR-models. Working Paper, University of Copenhagen, Institute of Mathematical Statistics; Econometrics J. 2 (1999) 306] are applied and it is shown that the dimension of the cointegration space is sample dependent while the estimated coefficients do not exhibit instability in recursive estimations.     

An empirical test of purchasing power parity in selected developing countries: a panel data approach

Abstract

This paper examines the empirical validity of Purchasing Power Parity (PPP) for certain large developing economies by using a panel unit root methodology. The test results show that a long run real exchange rate depreciation trend exists in certain developing countries. Without considering this depreciation trend, it is hard to verify the stationarity and to explain the existence of the extremely long half-lives of the real exchange rates. When a linear time trend is included in the tests, the results tend to support the stationarity of the underlying real exchange rate processes, and the half-lives are significantly shorter and their range can be explained by transitory disturbances.     

Regime changes and the sustainability of fiscal imbalance in East Asian countries

The main purpose of this paper is to assess empirically the fiscal policy regimes in five Asian countries using a formal framework based on the government's intertemporal budget constraints (GIBC). To this end, we relied on an array of time-series methods and quarterly data of nearly three decades. Our conclusions are; first, the evidence indicates that the fiscal stance in Thailand and South Korea are on their sustainable path while the Philippines and Malaysia demonstrate only ‘weak sustainability’. Second, revenues are growing at a rate faster than government spending for Singapore, a country that has recorded large surpluses for most of the sample period. Third, the results show a one-way causation from expenditure to revenue for Korea, Singapore and Thailand. This finding indicates that reducing the size of government spending may improve fiscal budget deficits without having to undergo changes in the overall strategy. Fourth, we observed a long-run feedback causality in the revenue–expenditure nexus for the case of Malaysia and the Philippines, which may require fiscal synchronization instrument policies to moderate the post-crisis fiscal imbalances. Together, the results demonstrate diverse fiscal patterns but they should be useful to understand the complexities of economic integration in the region.     

A wavelet-based panel unit-root test in the presence of an unknown structural break and cross-sectional dependency,with an application of purchasing power parity theory in developing countries

This article introduces two different non-parametric wavelet-based panel unit-root tests in the presence of unknown structural breaks and cross-sectional dependencies in the data. These tests are compared with a previously suggested non-parametric wavelet test, the parameteric Im-Pesaran and Shin (IPS) test and a Wald type of test. The results from the Monte Carlo simulations clearly show that the new wavelet-ratio tests are superior to the traditional tests both in terms of size and power in panel unit-root tests because of its robustness to cross-section dependency and structural breaks. Based on an empirical Central American panel application, we can, in contrast to previous research (where bias due to structural breaks is simply disregarded), find strong, clear-cut support for purchasing power parity (PPP) in this developing region.     

Information technology and firm performance: mediation role of absorptive capacity and corporate entrepreneurship in manufacturing SMEs

ABSTRACT

The success of small and medium-sized enterprises (SMEs) depends on dynamic capabilities, as it provides opportunities to remain competitive and perform well in the dynamic business environment. Although several studies show the significant positive impacts of dynamic capabilities on firm performance, our knowledge of the underlying mechanism through which IT capabilities affect the firm performance is not yet clear. Applying the dynamic capability view, this study investigates the intervening role of absorptive capacity and corporate entrepreneurship. The data of 417 respondents is collected from medium-sized manufacturing sector SMEs in Punjab, Pakistan. The research hypotheses have been analysed through the structural equation modelling method by using the Smart-PLS software. The research findings show that absorptive capacity and corporate entrepreneurship partially mediates the relationship between IT capabilities and firm performance. Furthermore, the sequential path of IT technical skills, absorptive capacity, corporate entrepreneurship, and firm performance is highly significant as compared to other paths.     

The role of corporate governance strength in crisis and non-crisis times

This study evaluates corporate governance practices of listed firms in the United Arab Emirates and investigates whether corporate governance mitigates/exacerbates the impact of leverage and risk on firm performance during crisis and non-crisis times. The study constructs a corporate governance index not only to examine the dispute of the role of corporate governance during the crisis but also its influence on other factors that fuelled the crisis. A firm-level panel data is used that spans the period 2008–2012 of all listed firms on Abu Dhabi Securities Exchange (ADX) and Dubai Financial Market (DFM). The study finds a positive influence of corporate governance strength on the accounting performance, but a negative influence on the firms’ economic performance. In normal times, corporate governance mitigates the negative influence of leverage and risk on the accounting and economic firm performance. However, this synergy effect varies across performance indicators during crisis.     

Ownership dynamics and firm performance in an emerging economy: a meta-analysis of the Russian literature

This paper provides a meta-analysis of studies on the effect of ownership on the performance of Russian firms over 20 years of rapid institutional and economic changes. We review 29 studies extracted from the EconLit and Web of Science databases with a total of 877 relevant estimates. We find that the government negatively affects company performance regardless of its administrative level. In contrast, private ownership is positively associated with firm performance. However, the effect size and statistical significance are notably varied among different types of private ownership. While the effect of insider (employee and management) ownership is comparable to that of foreign investors, the effect of domestic outsider investors is considerably smaller. Our assessment of publication selection bias reveals that the existing literature does not contain genuine evidence for a series of ownership types and, therefore, some of the findings have certain limitations.     

Patterns of technological specialisation in Latin American and East Asian countries: an analysis of patents and trade flows

This article provides an extensive analysis of the technological specialisation of three Latin American countries (Argentina, Brazil and Mexico) and two East Asian countries (South Korea and Taiwan). Technological specialisation is measured both with respect to patents and trade flows. This article provides different measures of technological specialisation: Ricardian and Smithian specialisation indexes and the contribution to trade balance. These indicators provide a new picture of the evolution of the patterns of technological specialisation. Latin American countries show a divergent technological specialisation from East Asian countries, since the 1970s. In particular, Latin American countries display weaknesses in computers and communications and electrical and electronic sectors and their specialisation in fast growing technological classes is declining, in contrast to East Asian countries. While East Asian countries have shifted to specialised supplier or science-based sectors, Latin American countries have increased their trade specialisation in supplier-dominated or scale-intensive sectors.     

A neglected contribution to monetary theory in the eighteenth century: Anders Wappengren on paper money,floating exchange rates,and purchasing power parity

Abstract

Between 1789 and 1803 the National Debt Office issued unbacked interest bearing notes whereas the Bank of Sweden issued silver backed notes. The massive note issuance by the National Debt Office led to different exchange rates and two units of account. The situation gave rise to an early paper standard theory formulated by Anders Wappengren, a well-read merchant who was strongly influenced by Adam Smith and the French physiocrats. Wappengren had a firm understanding of monetary systems and the adjustment mechanism under floating exchange rates, including such concepts as purchasing power parity and price stickiness.     

上市方式、大股东持股与民营上市公司的绩效

企业上市可以采取直接上市（IPO）和间接上市（买壳上市等）两种方式。本文考察了民营上市公司的不同上市方式下大股东持股与公司绩效间的关系。研究发现,间接上市的民营企业的大股东持股对公司绩效没有影响,而直接上市的民营企业的第一大股东持股与公司绩效存在正的线性关系,前5大股东持股与公司绩效呈非线性的U形关系。当考虑大股东持股的内生性时,发现间接上市的大股东持股与公司绩效互不影响,而直接上市的大股东持股与公司绩效互为正相关。     

INVESTMENT BEHAVIOUR,CORPORATE CONTROL,AND PRIVATE BENEFITS OF CONTROL: EVIDENCE FROM A SURVEY OF UKRAINIAN FIRMS

We analyse the impact of ownership and corporate control on firms’ investment using the 2001 survey of Yacoub et al. on Ukrainian firms. The model explains investment by output, financial and soft budget constraints, and corporate control (and ownership) categories potentially enjoying private benefits of control. We find that the corporate control model fits better than the ownership model, a negative relationship between state and employee control and firms’ investment, and evidence for the presence of soft budget constraints. A negative relationship between firms’ investment and the relative size of non‐monetary transactions strengthens the conclusion of private benefits of control impacting investment.
