In this study, we apply nonlinear panel unit-root test to assess the nonstationary properties of the real exchange rate for seven major Organization of the Petroleum Exporting Countries (OPEC). We find that nonlinear panel unit-root test has higher power than linear method suggested by Breuer et al. (2001) if the true data generating process of exchange rate is in fact a stationary nonlinear process. We re-examine the validity of Purchasing Power Parity (PPP) from the panel nonlinear point of view and provide robust evidence clearly indicating that PPP holds true for four countries, namely Angola, Indonesia, Iran and Saudi Arabia. Our findings point out their exchange rate adjustment is mean reversion towards PPP equilibrium values in a nonlinear way. 相似文献

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) at the 5% (10%) significance level. This result differs greatly from those of Juvenal and Taylor (2008), Imbs et al. (2003), Sarno et al. (2004) and Berka (2009), who report ample evidence for nonlinearity for the same or similarly disaggregated real exchange rate datasets. 相似文献

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) and Cerrato et al. (2009) 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. 相似文献

This article takes as its point of departure the herding model of Bikhchandani et al. (1992). We extend earlier experimental evidence to distinguish between informational herding, as in the model, and ownership herding, an alternative explanation for observed behaviour. 相似文献

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). 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) type model for Germany. The paper builds on the estimation strategy of Stockhammer, Onaran, and Ederer (2009) and Hein and Vogel (2008, 2009). 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. 相似文献

Economic theory is paying increasing attention to a non-observed economy (NOE) and its causes. Recently, a couple of works (Rosser et al., 2000, 2003) have claimed that there is a positive relationship between income inequality and the size of NOE. This supposed relationship is not so clear and deserves in-depth analysis. There is a crucial aspect that has been completely avoided in these studies: income inequality is mainly measured using ‘regular’ incomes and this fact could lead to some bias. The existence of a certain size of NOE implies some income evasion that can affect the inequality indexes used in the study of the relationship between NOE and inequality. Including the regional share of NOE in a wage equation, I find that, in the specific case of the Italian private sector employees, the income evasion attached to NOE tends to reduce inequality measured by regular wages statistics. 相似文献

The study re-examined the time series properties and regional disparities in Chinese inflation by extending the work of Chong, Zhang, and Feng (2011). 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, 2004) and a recently developed ADF type unit root test with two structural breaks of Narayan and Popp (2010). 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. 相似文献

Lopez et al. (2005) 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). 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. 相似文献

This paper introduces service innovation in the proximity-concentration trade-off model of trade and foreign direct investments (FDI) [Helpman, E., M. Melitz, and S. R. Yeaple 2004. “Export Versus FDI with Heterogeneous Firms.” American Economic Review 94 (1): 300–316]. The idea is that innovation will have two main effects on service firms’ choice between exports and FDI. First, innovative firms will on average have higher productivity levels than non-innovative enterprises. Secondly, innovators will have to pay a higher relational distance cost for undertaking export activities, and they will, therefore, prefer to avoid (or reduce) these costs by choosing an FDI strategy instead. We test the empirical relevance of this idea on a new survey data set for a representative sample of firms in all business service sectors in Norway. The results show that firms are more likely to choose FDI rather than export the greater their productivity level and the higher the relational distance costs they face. 相似文献

Based on the approach advanced by Elliott, Komunjer, and Timmermann (2005), we analyzed whether the loss function of a sample of exchange-rate forecasters is asymmetric in the forecast error. Using forecasts of the dollar/euro exchange rate, we found that the shape of the loss function varies across forecasters. Some forecasters appear to make forecasts under an asymmetric loss function, while a symmetric loss function seems to describe well the loss function of other forecasters. Accounting for an asymmetric loss function does not necessarily make forecasts ‘look’ rational. 相似文献

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) and Metzler (1949a, b). It is shown that the simultaneous occurrence of both paradoxical results is possible for some parameter values. 相似文献

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), 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%. 相似文献

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) test, we provide relatively more support for the theory, getting closer and closer towards solving the PPP puzzle. 相似文献

AbstractThe purpose of the study is twofold: first, it presents an extensive review of empirical studies that have examined the relationship between higher education and economic growth. Second, it estimates the effect of higher education on economic growth in Greece over the period 1960–2009. It applies the model introduced by Mankiw, Romer, and Weil (1992) by using the higher enrolment rates as a proxy of human capital. The paper employs cointegration and an error-correction model to test the causal relationship between higher education, physical capital investments and economic growth. The empirical analysis reveals that there is a long-run cointegrating relationship between higher education, physical capital investments and economic growth. The elasticity of economic growth with respect to higher education is 0.52%. The results also suggest that there is evidence of unidirectional long-run and short-run Granger causality running from higher education and physical capital investments to economic growth. 相似文献

Using DATASTREAM and LexisNexis databases, we examine the experience from 1995 to 2005 for eight European countries and 21 sectors, and compute the frequency of merger transactions at sectoral level, controlling for the roles of country variables and focusing on distinct technological patterns of innovation. We found that, even in market‐based countries, where transfer of control is a frequent phenomenon, mergers are less frequent in those sectors where innovation follows cumulative processes and where takeovers represent a ‘breach of knowledge.’ This study provides empirical support to the fruitful line of research of varieties of capitalism (Hall and Soskice 2001) and shows that sectoral differences in M&A (mergers and acquisitions) may be seen in their complementarities with differences by country and their institutional frameworks. Results confirm that acquisitions may occur even in those economies where block‐holders are present, but where the good quality of institutions leaves no space for defence against takeovers. It also highlights the significant role played by takeover regulation, and suggests that the recent reforms in European harmonization should be implemented, so that the obstacles impeding takeovers can be removed. However, policy‐makers should also try to identify for which economies and sectoral fields of specialization, merger activities produce more beneficial effects and which turn out to be detrimental. 相似文献

Although the attention of innovation studies has traditionally been focused on manufacturing, the differential features of innovation activities carried out by services are gaining more and more relevance in innovation research. The aim of this paper is to thoroughly analyse the data from the Spanish Innovation Survey 2000, the first large-scale innovation survey that included service activities in Spain, in order to identify the main patterns of innovation in Spanish services. The results of our investigations confirm that a high degree of heterogeneity, in relation to innovation patterns, exists among service firms and among service industries as well. Nevertheless, important similarities are found between pioneer classifications, such as the theoretical taxonomy of service industries by Soete and Miozzo (1989) or the classification of service firms elaborated by Hollenstein (2003), and the taxonomy we obtained by applying multivariate analysis. 相似文献

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) 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. 相似文献

There has been a recent resurgence of interest in debates about the power of business (Culpepper 2011; Bell 2012) and Bell and Hindmoor (2013) make an important, theoretically informed, but empirically rooted, contribution to that debate. In this response, we address both aspects of their contribution, arguing that their treatment of Lindblom is partial and, consequently, so is their explanation of the case. As such, we largely rely on their narrative of the evolution of the Australian mining tax, focusing first on critically examining Bell and Hindmoor's theoretical position, before turning to their analysis of the case. 相似文献

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) and Newey and West (1987) 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. 相似文献

Abstract Quetelet's contribution to statistics has received adequate attention in Stigler (1986, 1999) and Porter's (1986) seminal works on the history of that scientific discipline. 24 Our contribution investigates Quetelet's influence on economic methodology. Other scholars have already investigated his influence on econometrics and empirical economics (Morgan 1990, Stigler 1999), but we argue that his influence on theoretical economics should be considered significant as well. We devote attention to Quetelet's concept of the ‘average man’. For this purpose we briefly summarize Quetelet's methodology and examine the evolution of his ideas as expressed in his published works. We then investigate his influence on Jevons's ‘calculus of pleasures and pains’ and on the statistical investigations of the German historical school. We argue that the history of statistics, and especially Quetelet's contribution, should not be neglected by historians of economic thought as it provides important insights into the development of economic methodology. 相似文献
